Description

Technical Field

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

[0002] When assembling two or more components together, there must be a certain tolerance. One is due to the existence of a certain dimensional tolerance during the production of individual components themselves, 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 fastened to each other, there will also inevitably be a positional tolerance. And the existence of tolerance almost runs through the entire product life cycle, affecting the product quality, appearance, processing process route, detection, production and manufacturing cost, and the assembly of the final product, etc.

[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), which increases 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 fix the position of the screw rod and facilitate disassembly is one of the design directions.

A screw rod through hole is provided inside the fixing member. A screw rod is arranged inside the screw rod through hole. One end of the screw rod passes through the screw rod through hole. A positioning gasket is installed on the screw rod. The positioning gasket is respectively provided with a first buckle platform and a second buckle platform. The fixing member is respectively provided with an upper concave position and a lower concave position. The first buckle platform passes through the upper concave position and the first buckle platform is buckled at the edge of the upper concave position. The second buckle platform passes through the lower concave position and the second buckle platform is buckled at the edge of the lower concave position.

[0006] Specifically further, the fixing member is provided with a circular concave position. The upper concave position and the lower concave position are symmetrically distributed on the edge of the circular concave position. The positioning gasket is embedded in the circular concave position.

[0007] Specifically further, the edge of the fixing member is provided with a first convex platform and a second convex platform. The first buckle platform is buckled on the first convex platform. The second buckle platform is buckled on the second convex platform.

[0009] Specifically further, the positioning gasket is provided with convex teeth, and the convex teeth abut against the surface of the screw.

[0010] Specifically further, the positioning gasket is connected to the first snap table through a first bending portion, and the positioning gasket is connected to the second snap table through a second bending portion. The first bending portion is placed in the upper concave position, and the second bending portion is placed in the lower concave position.

[0011] Specifically further, there is a gap between the first bending portion and the inner wall of the upper concave position.

The second buckle 302 passes through the lower concave position 206 and the second buckle 302 is buckled at the edge of the lower concave position 206.

[0024] In this structure, the first buckle 301 passes through the upper concave position 205 and the first buckle 301 is buckled at the edge of the upper concave position 205. The second buckle 302 passes through the lower concave position 206 and the second buckle 302 is buckled at the edge of the lower concave position 206, so that the positioning gasket 3 positions the screw 1, making it not easy to separate from the screw 1, being able to quickly fix the position of the screw 1 and facilitating disassembly. The screw 1 can freely shift inside the screw hole to overcome the tolerance problem.

[0025] The thread 204 on the outer surface of the fixing member 2 can be screwed into the screw hole of the sheet metal part, and the screw 1 is screwed into the screw hole of another sheet metal part to connect between two sheet metal parts. Or, one of the sheet metal parts can be replaced with a handle or a plastic part to overcome the connection with different tolerances between parts.

[0026] In this structure, the fixing member 2 is provided with a circular concave position 201. The upper concave position 205 and the lower concave position 206 are symmetrically distributed on the edge of the circular concave position 201.

The first buckle 301 is buckled on the first protrusion 203, and the second buckle 302 is buckled on the second protrusion 208. The second protrusion 208 and the first protrusion 203 strengthen the rigidity of the edge and help the positioning gasket 3 to be fixed in position. After being buckled, the positioning gasket 3 cannot move forward and backward along the screw 1.

[0028] On the surface of the fixing member 2 of this structure, an upper opening 207 and a lower opening 209 are respectively provided. The lower opening 209 is located at the other side position of the upper opening 207, and the lower opening 209 is shown in the attached drawing. The first fastening platform 301 and the second fastening platform 302 respectively pass through the upper opening 207 and the lower opening 209, facilitating the fastening function. The second convex platform 208 and the first convex platform 203 respectively correspond to the upper opening 207 and the lower opening 209.

[0029] The positioning gasket 3 of this structure is provided with convex teeth 303, and the convex teeth 303 abut against the surface of the screw 1. The convex teeth 303 position the screw 1.

[0030] The positioning gasket 3 of this structure is connected to the first fastening platform 301 through a first bending portion, and the positioning gasket 3 is connected to the second fastening platform 302 through a second bending portion. The first bending portion is placed in the upper concave position 205, and the second bending portion is placed in the lower concave position 206.
