Description
Technical field
The present invention relates to a kind of bolt, belong to bolt technical field.
Background technology
Bolt, as a kind of securing member connected for object, is widely used on various apparatus.Apparatus
Maintenance, in Renewal process, bolt is repeatedly tightened and is unscrewed.So that screw bolt abrasion ratio is more serious,
After the bolt head of some bolt repeatedly clamps, its corner angle can become round, even if wanting the bolt more renewed, this
It is difficult to turn whole bolt at instrument clamping bolt heads such as using spanner time individual.
Summary of the invention
It is an object of the invention to: a kind of bolt is provided, this bolt can in the case of bolt head lost efficacy,
By its screw-threaded counterbore, bolt is unscrewed, and this type bolt need not other pad in use.
Technical scheme: a kind of bolt, includes integrated screw rod and bolt head, far
The screw-threaded counterbore of 1 and screw coaxial it is provided with on the bolt head upper surface of screw rod, this screw-threaded counterbore
Hand of spiral is in opposite direction with screw flight, the bottom surface that bolt head is connected with screw rod is 1 umbellate form
Pad, the bottom surface of umbellate form pad is the arcuate surface concaved, and the bottom surface of umbellate form pad offers 1
Draw-in groove more than bar, after bolt is tightened, enters, in bolt head upper cover, the protective cover that plastics are made.
Above-mentioned bolt, the aperture of described screw-threaded counterbore is 0.5 1 times of screw rod bar footpath.
Above-mentioned bolt, the degree of depth of described screw-threaded counterbore is 0.8 1.2 times of bolt head thickness.
Above-mentioned bolt, described draw-in groove is oblique draw-in groove, and its oblique direction is identical with screw flight rotation direction.
Beneficial effects of the present invention: the present invention sinks by being provided with 1 screw thread on the upper surface of bolt head
Hole, when the bolt head of this type bolt be worn cannot by fall unscrew time, it is possible to use additionally
Bolt is threaded in counterbore, due to rotation direction and screw rod oppositely oriented, firmly by bolt of screw-threaded counterbore
During being threaded into counterbore, the bolt of inefficacy can be unscrewed, consequently facilitating the bolt more renewed；This is new
Bolt in use, bottom surface deforms after contacting with piece surface, produce elastic deformation force,
This elastic deformation force makes bolt head bottom surface together with fitting tightly between piece surface；And at umbellate form
Being provided with oblique draw-in groove on the bottom surface of pad, draw-in groove is oblique identical with screw rod rotation direction, and this screw rod is screwed into
During, draw-in groove can snap on piece surface, and the frictional force between bolt and part becomes big, thus avoids
Bolt is easy when vibration uses than in the case of more serious to come off, and need not volume in installation process
Outer pad, has saved operation, also saves cost；And it is provided with protective cover, one can avoid spiral shell
When bolt head uses in an outdoor environment, after long-term exposure, get rusty easily damage, and two avoid rainwater to enter
In screw-threaded counterbore so that screw-threaded counterbore is got rusty damage, when needs use screw-threaded counterbore to looser a bolt,
Bolt hole cannot use.The bolt of the present invention has done the structural adjustment that some are small on existing structure,
But practicality is stronger, there is good use value.
Accompanying drawing explanation
Accompanying drawing 1 is the main TV structure schematic diagram of the present invention；
Accompanying drawing 2 is the plan structure schematic diagram of the present invention；
Reference: 1-screw rod, 2-bolt head, 3-screw-threaded counterbore, 4-umbellate form pad, 5-draw-in groove, 6-
Protective cover.
Detailed description of the invention
Embodiments of the invention: a kind of bolt, as shown in accompanying drawing 1-2, include integrated screw rod
1 and bolt head 2, away from be provided with on bolt head 2 upper surface of screw rod 11 with screw rod 1 with
The screw-threaded counterbore 3 of axle, the hand of spiral of this screw-threaded counterbore 3 is contrary with the hand of spiral of screw rod 1, bolt
Be 1 umbellate form pad 4 on 2 bottom surfaces being connected with screw rod 1, the bottom surface of umbellate form pad 4 be to
The arcuate surface of indent, the bottom surface of umbellate form pad 4 offers the draw-in groove 5 of more than 1, and bolt is tightened
After, enter, in bolt head 2 upper cover, the protective cover 6 that plastics are made.
When this new bolt uses, the umbellate form pad during screw rod 1 is screwed into, on bolt head 2 bottom surface
4 can contact with piece surface, owing to the bottom surface of umbellate form pad 4 is arcuate surface, in contact process firmly
After being screwed into, its bottom surface is easy for deformation, fits with piece surface, increases between bolt and part
Frictional force, and on the bottom surface of umbellate form pad 4, it is further opened with draw-in groove 5, umbellate form pad 4 connects with part
Touch, in deformation process, draw-in groove 5 can snap onto in piece surface, so that it is more firm to connect effect
Gu, it is to avoid in the case of serious vibration, bolt there will be loosening.After bolt is used for multiple times, its spiral shell
Each corner angle of bolt head 2 can gradually be worn, and when bolt is unscrewed by needs, uses the fixtures such as spanner
Grip bolt head 2 is just difficult to looser a bolt, and a screw can be used this time to be threaded into counterbore
In 3, owing to the thread rotary orientation of screw-threaded counterbore 3 is contrary with the thread rotary orientation of screw rod 1, screw is not
In disconnected rundown process, then bolt can be unscrewed, then replace with new bolt.Owing to bolt is long
Phase is exposed to outside, and when using the most in an outdoor environment, bolt is easily subject to the effect of rainwater, gets rusty
Damaging, therefore enter the protective cover 6 of a plastic support in bolt head 2 upper cover, one can protect bolt
2 will not rainwater effect, two can avoid rainwater to enter in screw-threaded counterbore 3 so that screw thread sinks
Get rusty damage in hole 3.
This bolt is in manufacturing process, and the aperture of its screw-threaded counterbore 3 is 0.5 1 times of screw rod 1 bar footpath,
The degree of depth of screw-threaded counterbore 3 is 0.8 1.2 times of bolt head 2 thickness.One guarantees screw-threaded counterbore 3
Structure does not interferes with the performance of this bolt, and two avoid that the aperture of screw-threaded counterbore 3 is the least, the degree of depth is the most shallow
If, screw is easy failure mode during being screwed into, it is difficult to play a role.
And draw-in groove 5 manufacturing process can be oblique draw-in groove, the thread rotary orientation phase of its oblique direction and screw rod 1
With.Like this, during screw rod 1 screws in, its oblique draw-in groove will constantly snap onto piece surface
In so that contacting between bolt with part is better.
