Description

Technical Field

[0001] The utility model specifically relates to a tolerance adjuster with quick positioning. Background Art

[0002] When there are two or more holes on a workpiece, there must be a certain tolerance between the two holes or multiple holes. One is due to certain dimensional tolerances during production itself, that is, during the manufacturing process of parts, due to the influence of factors such as processing or measurement, there is always a certain error in the actual size after completion; the other is that when two components are connected by multiple bolts, there will also inevitably be positional tolerances. And the existence of tolerances almost runs through the entire product life cycle, affecting the quality, aesthetics, processing process route, inspection, production manufacturing cost, and final product assembly of the product.

[0003] The existing tolerance adjuster with a fixed positioning gasket position does not have a lock nut. The lock nut needs to be welded to the component (such as a sheet metal part), increasing the processing cost of the component. For example, a manual three-way tolerance adjuster with a fixed positioning gasket position disclosed in the publication number CN211598134U. In the field of tolerance adjusters with a fixed positioning gasket position, how to implement the fixation of the screw position and facilitate disassembly is one of the design directions. Summary of the Invention

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the utility model is to provide a tolerance adjuster with a fixed positioning gasket position, which can quickly fix the screw position and facilitate disassembly, and overcome the tolerance problem.

[0005] According to a tolerance adjuster with quick positioning of the utility model, it includes a fixing member. The outer surface of the fixing member is provided with screw threads. A screw through hole is provided at the bottom position of the fixing member. A screw is inserted into the screw through hole. First support bars and second support bars are provided on the inner wall of the fixing member. The first support bars and the second support bars respectively abut against the edges of the screw. The diameter of the screw through hole is larger than the diameter of the screw.

[0006] Specifically further, an opening is provided on the surface of the fixing member. The first support bars are located on the inner wall of the opening.

[0007] Specifically further, two auxiliary holes are provided on the side of the screw through hole.

[0008] Specifically further, the two auxiliary holes are symmetrically distributed.

[0009] Specifically further, the first support bars are obliquely arranged.

[0010] Specifically further, the second support bars are obliquely arranged.

[0011] The beneficial effects of the present utility model are as follows: In this structure, the first support bar and the second support bar respectively abut against the edges of the screw rod, enabling the screw rod to be quickly positioned. In combination with the fact that the diameter of the screw rod through - hole is larger than the diameter of the screw rod, the position of the screw rod can be adjusted to solve the problem of tolerance. Additionally, by squeezing the first support bar and the second support bar, the tops of the first support bar and the second support bar can be made to leave the edges of the screw rod, and the screw rod can be disengaged from the screw rod through - hole, implementing the advantage of quick disassembly.

[0018] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0019] Next, refer to Figures 1 to 3 Describe a tolerance adjuster with quick positioning according to an embodiment of the present utility model, which includes a fixing part 2. The outer surface of the fixing part 2 is provided with a thread 201. A screw rod through - hole 204 is provided at the bottom position of the fixing part 2. A screw rod 1 is inserted into the screw rod through - hole 204. A first support bar 203 and a second support bar 206 are provided on the inner wall of the fixing part 2. The first support bar 203 and the second support bar 206 respectively abut against the edges of the screw rod 1, and the diameter of the screw rod through - hole 204 is larger than the diameter of the screw rod 1.

[0020] This structure positions the screw 1 quickly by means of the first support bar 203 and the second support bar 206 respectively against the edges of the screw 1. The diameter of the screw through-hole 204 is larger than that of the screw 1, which is used to adjust the position of the screw 1 to solve the tolerance problem. In addition, by squeezing the first support bar 203 and the second support bar 206, the tops of the first support bar 203 and the second support bar 206 are made to leave the edges of the screw 1, and the screw 1 can be disengaged from the screw through-hole 204, which realizes the advantage of quick disassembly.

[0021] When this structure is used in combination, such as when two or more are used in cooperation, the screw 1 can be screwed onto the screw holes of a plastic plate or a sheet metal part to play a positioning role, which helps to overcome the tolerance problem existing between the corresponding center distances during the production of the plastic plate or the sheet metal part. By pushing the position of the fixing part 2, the screw 1 can move to the corresponding position in the main through-hole 204, which plays a role in fixing the center distance tolerance of the mating parts. In addition, the fixing part 2 is screwed onto another plastic plate or sheet metal part or handle through the screw thread 201 to play a fixing role.

[0022] An opening 202 is provided on the surface of the fixing part 2 of this structure. The first support bar 203 is located on the inner wall of the opening 202. By squeezing the first support bar 203, the first support bar 203 deforms outward from the opening 202, and the top of the first support bar 203 leaves the edge of the screw 1. Similarly, the second support bar 206 also deforms outward under extrusion and also disengages from the edge of the screw 1. At this time, the screw 1 can also be disassembled.

[0023] Two auxiliary openings 205 are provided on the side of the screw through-hole 204 of this structure, through which the state of the screw 1 can be observed. The two auxiliary openings 205 of this structure are symmetrically distributed. A finger or a tool passes through the auxiliary opening 205 to push the screw 1.

[0024] The first support bar 203 of this structure is obliquely arranged; the second support bar 206 of this structure is obliquely arranged, which enables the screw 1 to slide on the inclined surface of the first support bar 203, facilitating the quick installation of the screw 1 onto the screw through-hole 204.

[0025] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
