Description

Tolerance compensator

Technical Field

The present invention relates to a tolerance compensator, in particular for use between components connected to each other.

Background

The invention patent application with application publication number CN103994131A discloses a tolerance compensation device comprising a hollow cylindrical basic element and a hollow cylindrical compensation element, which is in threaded engagement with the basic element and can be moved from a starting position into a compensation position by rotation relative to the basic element. The device is characterized in that a fixing member is provided, by means of which the compensating element can be fixed in the compensating position relative to the base element.

However, since the above tolerance compensation device is threadedly engaged with the base element and can be moved from the initial position to the compensation position by rotation relative to the base element, but the compensation element is not positioned in the factory state (i.e. in the initial position) relative to the base element, during transportation after factory shipment, due to vibrations and the like, the compensation element may move axially relative to the base element and even be released from the base element rather than being maintained in the factory state, which may cause inconvenience in installation. In addition, the tolerance compensation equipment is fastened on the first component by means of the snap-in nut which is large in size and complex in structure, can only be clamped at the edge of the first component, and is limited in use position.

the basic assembly 01 is composed of a cylindrical bracket 14 and a nut 15 embedded in the cylindrical bracket, wherein the nut 15 is provided with a threaded hole 11, the cylindrical bracket 14 is provided with a fixing structure 12 used for fixing the cylindrical bracket on a member, and the fixing structure is two hooks 17 respectively arranged at the end parts of two legs 16;

the compensating assembly 02 is composed of a compensating element 25 and a driving element 26 shown in fig. 13-14, the compensating element 25 is provided with a through hole 27, the driving element 26 is in a sleeve shape and is tightly matched in the through hole 27, the driving element 26 is provided with an external convex rib 28 used for being tightly matched with the compensating element and an internal convex rib 29 used for being matched with a screw rod, the driving element 26 is made into a closed sleeve shape by plastic, and the driving element has elastic deformation capacity by virtue of the property of the plastic material; the assembly of the compensating assembly with the basic assembly is achieved by the compensating element 25 by means of its external thread 21 cooperating with the threaded hole 11, so that the compensating assembly can be moved in rotation relative to the basic assembly from a starting position, in which the compensating assembly is retracted into the basic assembly so that the axial dimension of the entire tolerance compensator is relatively short in order to leave a large space for placing another component to be connected, to a compensating position, in which the compensating assembly projects a longer length out of the basic assembly so that the axial dimension of the entire tolerance compensator is increased for support between the two components to be connected.

The external thread 21 and the threaded hole 11 are threaded in the opposite direction to the bolt for connecting the two components, and when the bolt is to be connected from one component to the other component through the driving element, the compensating assembly is rotated together with the bolt by screwing the bolt and friction between the bolt and the driving element, so that the compensating assembly is rotated relative to the base assembly to move from the initial position to the compensating position, and then the bolt is rotated relative to the driving element, so that the two components are fastened.

The end of the cylindrical support 14 of the basic module 01 has two teeth 13 as a first positioning structure, the compensating element 25 of the compensating module 02 has a disc 23 facing the end of the cylindrical support, the surface of the disc 23 facing the teeth is provided with splines 22 as a second positioning structure, the teeth 13, splines 22 are distributed in the direction of rotation of the compensating module relative to the basic module, i.e. along the circumference of the disc, the teeth or/and splines are elastic so as to be elastically deformable, the cylindrical support is preferably made of a plastic material, so as to give the teeth elasticity by the elasticity of the plastic. The teeth are positioned in the gullets to interlock when the compensation assembly is in the home position, preventing rotation of the compensation assembly relative to the base assembly. It is easy to think that the tooth and the disc can be transposed to realize the transposition of the tooth and the tooth groove.

One side of the tooth has a steep slope and the other side of the tooth has a gentle slope, the tooth space is shaped to match the shape of the tooth, the tooth space is formed by a spur 24 on both sides of the tooth, the shape of the tooth space is the same as the shape of the tooth, and the gentle slope of the tooth slides over the spur and out of the tooth space when the compensating assembly is moved relative to the base assembly from the starting position to the compensating position.
