Abstract

The utility model relates to a fastening device for positioning a magnetic disk unit, which comprises a main body and press fasteners, wherein, the main body is provided with positioning holes, strengthening ribs and two assembling convex posts. The positioning holes are arranged at the middle position of the main body, and the strengthening ribs are arranged on both ends of the outer margins of both sides of the main body. A convex block is convexly arranged below the press fastener, and limited posts, jacks and dummy clubs are correspondingly arranged outside a rack body of the magnetic disk unit rack, and the rack body is used for positioning a magnetic disk. After the limited posts are penetrated and positioned in the positioning holes by the fastening device, the two press fasteners of the fastening device can be simultaneously pressed downwards to cause the convex block to be fastened on a fastening hole of the dummy club and cause the convex posts to be inserted into the jacks so as to achieve a positioning mode without screws and further improve the convenience for disassembling and assembling the magnetic disk unit.

Description

The bayonet unit of disk drive location usefulness

The utility model relates to the bayonet unit of a kind of disk drive location usefulness, is meant especially by easy Elastic buckle structure, and dismounting, assembling and the device of locating that can convenient disk drive.

Along with the rapid progress of electronic industry, Related product quality that circulates on the market or output all are to change with rapid changepl. never-ending changes and improvementsly, and wherein the rapid universalness of computer is exactly an example the most tangible.And the fixed form of traditional disk drive is with screw it is locked on the disk frame, therefore for all comparatively loaded down with trivial details, not only time-consuming in the dismounting of disk drive, the assembling, and the misgivings of being afraid of that the screw loss is dropped is arranged.

Fundamental purpose of the present utility model provides the bayonet unit of a kind of disk drive location usefulness, it is because rather inconvenient in the dismounting of disk drive, assembling, and a kind of bayonet unit that does not have the disk drive location usefulness of screw locator meams of development, with the convenience that improves the disk drive disassembly and assembly is improved emphasis, meets industry demand and value to reach.

The utility model is achieved in that this bayonet unit includes body and clinching part two parts, wherein body has pilot hole, strengthens rib and two assembling projections, pilot hole is located at the body centre position, strengthen rib and be located at body both sides exterior rim, projection is for being convexly set on the inboard both ends of body, the clinching part is located at the two ends of body, locate to convex with projection below this clinching part: the disk frame is provided with limited post, jack and lug relatively for the support body outside of positioning disk machine, and wherein jack is for coincideing corresponding to the jack of disk drive sidepiece; By bayonet unit with pilot hole for after limited post runs through the location, two clinching parts of bayonet unit can be pressed down simultaneously so that projection is snapped on the button hole of lug, and projection is planted in the jack, really disk drive is located.

Bayonet unit of the present utility model includes body and clinching part two parts, and body has pilot hole, strengthens rib and two groups of projections, and wherein pilot hole is located at the body centre position, strengthens rib and is located at body both sides outer rim, and projection is to be convexly equipped with on inboard both ends; The clinching part is located at the two ends of body, locates to convex with projection below this clinching part.In order to achieve the above object, the utility model is provided with limited post, jack and lug relatively in the support body outside that the disk frame has for the positioning disk machine, and wherein jack is for coincideing corresponding to the hole of disk drive sidepiece; By bayonet unit with pilot hole for after limited post runs through the location, two clinching parts of bayonet unit can be pressed down simultaneously so that projection is snapped on the button hole of lug, and projection is planted in the jack, really disk drive is located.

Below in conjunction with embodiment of the present utility model and accompanying drawing, its structure, feature and effect are elaborated:

Fig. 1 is a stereo appearance figure of the present utility model.

Fig. 2 is applied to the enforcement illustration of disk frame for the utility model.

Fig. 3 is applied to the exploded view of disk frame for the utility model.

Fig. 4 is the partial cutaway schematic of the package assembly relation between display card buckle device and the disk frame.

Fig. 5 is the positioning states synoptic diagram between display card buckle device and the disk frame.

Fig. 6 is the synoptic diagram of finishing the location between display card buckle device and the disk frame.

Fig. 7 is the synoptic diagram of the released state between display card buckle device and the disk frame.

At first see also Fig. 1 to shown in Figure 4, the disk frame 2 that the utility model includes bayonet unit 1 and cooperates, wherein bayonet unit 1 is to be made into integration a curved arc shape, it includes body 11 and clinching part 12, this body 11 is provided with a pilot hole 111 in the centre position, the both sides exterior rim of body 11 is provided with and prevents bayonet unit 1 distortion and the reinforcement rib 112 that fractures, and respectively convexes with projection 113 on body 11 inboard both ends; Above-mentioned clinching part 12 is located on the two ends of body 11, and and the reinforcement rib 112 of body 11 between have certain spacing, for clinching part 12 when the interior pressure activity, can have certain elastic reaction space, this clinching part 12 includes projection 121 and pulls splenium 122, and its projection 121 is located at and is pulled splenium 122 lower outer.

One disk frame 2, can supply ccontaining disk drive 3, side frame body is provided with the guide rail 21 of relative position in this disk frame 2, be beneficial to disk drive 3 and slip into setting, side locations after this disk frame 2 is provided with respect to disk drive 3 is provided with limited post 22, jack 23 and lug 24, wherein two lugs 24 of disk frame 2 are corresponding to the position of bayonet unit 1 clinching part 12, two jacks 23 are for being fit to projection 113 positions of bayonet unit 1, the limited post 22 of disk frame 2 evaginations then can be inserted and be made bayonet unit 1 location in the pilot hole 111 of bayonet unit 1, and disk drive 3 is slipping into when being located in the disk frame 2, just can locate after being slipped into certain stroke, the jack 31 of disk drive 3 both sides is communicated with the jack 23 of disk frame 2.

See also Fig. 5 and shown in Figure 6, when bayonet unit 1 is desired to combine disk drive 3 location with disk frame 2, pilot hole 111 on bayonet unit 1 body 11 is to wear earlier as for location on the limited post 22 of disk frame 2, and makes projection 113 aim at the jack 23 of disk frames 2.Because the both sides of bayonet unit 1 are outside curved arc shape, therefore but voltage supply fastener 12 has the space of an elasticity clinching, when bayonet unit 1 two ends clinching part 12 is inwardly pressed, the projection 121 of its D type just can make bayonet unit 1 fixing in the button hole 241 by its cambered surface importing lug 24, in 12 clinchings of clinching part simultaneously, projection 113 also places in the jack 31 of disk frame 2 jacks 23 and disk drive 3, and with disk drive 3 location.

See also shown in Figure 7, when desire assembling dress disk drive 3, owing to be formed with an elastic reaction space between the reinforcement rib 112 of clinching part 12 and bayonet unit 1, make and utilize the splenium 122 of pulling to press work in the work relatively two clinching parts 12, the unlikely rib 112 that is reinforced hinders, and can make the projection 121 of clinching part 12 and the button hole 241 disengaging buckle states of lug 24, get and can easily disk drive 3 be unloaded.

In sum, the utility model not only changes the fixed form of traditional magnetic disk machine with brand-new structural design, and can be by this one " bayonet unit of disk drive location usefulness " reach practical, operation effect easily and easily.
