Summary of the invention
(1) to solve the technical problem that
The technical problem to be solved in the present invention is to provide a kind of link-type mechanical elevating table, and it can arbitrarily be adjusted Joint height of table top, and Stability Analysis of Structures, intensity is high, easy and simple to handle the most laborsaving.
(2) technical scheme
For solving above-mentioned technical problem, the technical solution adopted in the present invention is:
A kind of link-type mechanical elevating table, including desktop (1), base (2) and lowering or hoisting gear, described Lowering or hoisting gear is two groups, and is located at described base (2) both sides, upper surface;Described lowering or hoisting gear includes pipe Set (3), screw rod (5) and intermeshing first gear of vertical direction (9) and the second gear (10), Described screw rod (5) is installed in described pipe box (3) and top connects described desktop (1), described pipe Set (3) bottom is connected on described base (2), and described first gear (9) passes through female thread and institute State screw rod (5) threaded and be installed on described pipe box (3) top, on described first gear (9) Side is provided with annulus (8), and described annulus (8) is set on described screw rod (5) and and this screw rod (5) Forming matched in clearance, described annulus (8) bridges by connecting post (11) and described pipe box (3); The axostylus axostyle (12) of horizontally set it is fixed with, the upper set of described axostylus axostyle (12) on described pipe box (3) sidewall Equipped with axle sleeve (7), described axle sleeve (7) two ends respectively connect the second gear (10) described in
Described lowering or hoisting gear also includes one and threaded the first nut (6) of described screw rod (5), institute Stating the first nut (6) lateral surface and be provided with second handle (13), described first nut (6) is positioned at described Annulus (8) top;
Described first gear (9) and the second gear (10) are angular wheel.
Described axle sleeve (7) is provided with first handle (4).
As preferably, described connection post (11) two ends are respectively welded at described annulus (8) and pipe box (3) Sidewall on.
(3) beneficial effect
The present invention is compared to prior art, and it has the advantages that by two helical gear Engagement drives screw rod that desktop can be made to be freely lifted;Owing to annulus bridges by connecting post and pipe box, make liter Falling unit stabilized structure, intensity enhancing;Lowering or hoisting gear can be locked by retaining mechanism, makes desk exist During use more firm, will not because of maloperation cause desktop lifting occur potential safety hazard;Due in left and right Side is respectively provided with a lowering or hoisting gear, and is connected by axostylus axostyle axle sleeve structure so that operate more laborsaving, can It is applied to large-scale or heavier desk body.
Accompanying drawing explanation
Fig. 1 is the structure chart of the link-type mechanical elevating table of the present invention.
Fig. 2 is the partial enlarged drawing of the part A of Fig. 1.
Fig. 3 is the structure chart at another visual angle of the link-type mechanical elevating table of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail. Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
A kind of link-type mechanical elevating table as shown in Figure 1, Figure 2 and Figure 3, including desktop 1, base 2 and lowering or hoisting gear, lowering or hoisting gear is two groups, and is located at both sides, base 2 upper surface.
Lowering or hoisting gear includes intermeshing first gear 9 of pipe box 3, screw rod 5 and vertical direction and Two gears 10, screw rod 5 is installed in pipe box 3 and top connects desktop 1, and pipe box 3 bottom is connected to On base 2, the first gear 9 is threaded by female thread and screw rod 5 and is installed on above pipe box 3, First gear 9 is arranged over annulus 8, annulus 8 be set on screw rod 5 and and this screw rod 5 formed between Gap coordinates, and annulus 8 bridges by connecting post 11 and pipe box 3.
It is fixed with the axostylus axostyle 12 of horizontally set on pipe box 3 sidewall, axostylus axostyle 12 is set with axle sleeve 7, axle Overlap 7 two ends and respectively connect one second gear 10.
Connect post 11 two ends to be respectively welded on the sidewall of annulus 8 and pipe box 3.
First gear 9 and the second gear 10 are angular wheel.
Axle sleeve 7 is provided with first handle 4.
Lowering or hoisting gear also includes a retaining mechanism, retaining mechanism include one and screw rod 5 threaded One nut 6, the first nut 6 lateral surface is provided with second handle 13, and the first nut 6 is positioned on annulus 8 Side.
During work, first by retaining mechanism rotate in an anti-clockwise direction, retaining mechanism is made to rise to and annular Becoming certain spacing, shake first handle to drive axle sleeve to rotate, axle sleeve driven gear engaging structure operates, Due to female thread and the screw rod engagement of the first gear, make screw rod lift, reach the lifting effect of desktop. After height required for arriving, by retaining mechanism rotationally clockwise, make the following table of the first nut Face fits tightly the upper surface of annulus, so that it may locked by this lowering or hoisting gear.
The present invention drives screw rod that desktop can be made to be freely lifted by two helical gear engagements;Due to annulus Bridge by connecting post and pipe box, make lifting device structure consolidate, intensity enhancing;Retaining mechanism can be right Lowering or hoisting gear is locked, and makes desk the most firm, will not cause desktop liter because of maloperation There is potential safety hazard in fall;Owing to being respectively provided with a lowering or hoisting gear at left and right sides, and tied by axostylus axostyle axle sleeve Structure connects so that operates more laborsaving, can be applicable to large-scale or heavier desk body.
The above is only the preferred embodiment of the present invention, it is noted that for the art For those of ordinary skill, on the premise of without departing from the technology of the present invention principle, it is also possible to make some Improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
