Description

Technical Field

[0001] The utility model specifically relates to a tolerance adjuster. 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 inevitably be positional tolerances. And the existence of tolerances almost runs through the entire product life cycle, affecting product quality, aesthetics, processing process routes, inspection, production manufacturing costs, and the assembly of the final product, etc.

[0003] The existing tolerance adjusters do not have lock nuts. The lock nuts need to be welded to components (such as sheet metal parts), increasing the processing cost of the components. For example, in a manual three-way tolerance adjuster disclosed in CN211598134U in the field of tolerance adjusters, how to implement the locking screw 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 propose a tolerance adjuster that can be easily disassembled and can overcome tolerance problems to achieve quick fixation.

The fixing member is provided with a concave position. A main through hole is provided in the middle position of the concave position. A screw rod is installed in the through cavity of the main through hole. One end of the screw rod passes through the main through hole and a positioning gasket is sleeved on one end of the screw rod. The positioning gasket is located on the concave position. The diameter of the main through hole is larger than the diameter of the screw rod.

[0006] Specifically further, the positioning gasket is provided with a middle hole. The inner wall of the middle hole is provided with convex teeth, and the convex teeth abut against the surface of the screw rod.

[0007] Specifically further, the surface of the fixing member is provided with a side opening, and an elastic block is provided on the inner wall of the side opening.

[0008] Specifically further, there is a gap between both sides of the elastic block and the side opening.

[0009] Specifically further, the distance between the inner wall of the main through hole and the outer wall of the screw rod is at least 5 mm.

[0010] Specifically further, the diameter of the positioning gasket is smaller than the diameter of the concave position.

[0011] Specifically further, there is a spacing of at least 5 mm between the outer surface of the positioning gasket and the inner wall of the concave position.

[0012] The beneficial effect of the present utility model is that: in this structure, a positioning gasket is sleeved on one end of the screw rod, so that the screw rod is fixed on the fixing member, facilitating the disassembly of the locking nut. And the positioning gasket is located on the concave position, the diameter of the main through hole is larger than the diameter of the screw rod, enabling the screw rod to move freely in the main through hole, overcoming the tolerance problem of the connection position and achieving quick fixation.

[0019] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0020] The following refers to Figures 1 to 3 Describe a tolerance adjuster according to an embodiment of the present utility model, including a fixing member 2. The surface of the fixing member 2 is provided with a thread 201. The fixing member 2 is provided with a concave position 202. A main through hole 204 is provided at the middle position of the concave position 202. A screw rod 1 is installed in the through cavity 203 of the main through hole 204. One end of the screw rod 1 passes through the main through hole 204 and a positioning gasket 3 is sleeved on one end of the screw rod 1. The positioning gasket 3 is located on the concave position 202, and the diameter of the main through hole 204 is larger than the diameter of the screw rod 1.

[0021] In this structure, a positioning gasket 3 is sleeved on one end of the screw 1, so that the screw 1 is fixed on the fixing part 2. When the positioning gasket 3 is separated from the screw 1, the screw 1 is easy to disassemble. And the positioning gasket 3 is located on the concave position 202, and the diameter of the main through hole 204 is larger than that of the screw 1, enabling the screw 1 to move freely in the main through hole 204, and quickly fixing to overcome the tolerance problem of the connection position.
