Abstract

The utility model relates to an assembly configuration of a door lock handle and a square key, which comprises a handle and a square key which are inlaid with each other for position. A blind hole is arranged at the axes of of both ends of the square key. An end of the blind hole is ringent, which is inlaid with an abnormity spring. The flexibility surface of the abnormity spring is convex, which is matched with a fixed screw bolt jointed on the handle. The utility model can solve the problem on current assembly configuration between door lock handle and a square key, which is easily loose and fallen and also bad on the connection reliability. In addition, the utility model can also solve the tolerance and abrasion problem on the match between the handle and square key, increase the connection compactness, reduce the joggled spacing and enhance the position steadiness and freedom, which has the advantages of simple structure, convenient assembly and strong reliability.

Description

Door lock handle and square key assembly structure

The utility model relates to a kind of Door lock handle and square key assembly structure.

In traditional hand holding lock, handle was realized with locating slot such as cooperating of groove, fluting or translot on the square key by the addendum cone screw that is screwed onto on the handle with being connected generally of square key, because the long-term cumulative limit that uses wearing and tearing to produce, loosening and the obscission of handle and square key happen occasionally, simultaneously, also can cause the shakiness that cooperates of handle and square key because the correspondence position of technological reason addendum cone screw and locating slot is difficult to accurately definitely.

The purpose of this utility model is the relatively poor problem of easy loose or dislocation, connection reliability that solves existing Door lock handle and the existence of square key assembly structure.The utility model comprises the handle and the square key of mutual grafting location, is provided with blind hole at the two ends of square key along axis, a side opening of blind hole and setting-in deformed spring, and the elastic surface of deformed spring matches with trip bolt on being screwed onto handle.

The elastic surface of deformed spring is a convex surface.

The utility model is by above-mentioned specific design, tolerance and wear problem in having solved handle and square key cooperating, increased the tight ness rating that connects, reduced the swing space, and the randomness and the steadiness of location be enhanced, have simple in structure, assembling is easy, the advantage of good reliability.

Below in conjunction with drawings and Examples detailed content of the present utility model is described.

Accompanying drawing is a structural representation of the present utility model;

As shown in the figure, the utility model comprises the handle 1 and the square key 2 of mutual grafting location, two ends at square key 2 are provided with blind hole 3 along axis, one side opening of blind hole 3 and setting-in deformed spring 4, the elastic surface of deformed spring 4 is convex surfaces, and the elastic surface of deformed spring 4 matches with trip bolt 5 on being screwed onto handle 1.Trip bolt 5 roof pressures have on the elastic surface of larger area deformed spring 4 under confined state, have improved the randomness and the steadiness of location greatly.

Claims

1, a kind of Door lock handle and square key assembly structure, the handle and the square key that comprise mutual grafting location, it is characterized in that being provided with blind hole (3) along axis at the two ends of square key (2), one side opening of blind hole (3) and setting-in deformed spring (4), the elastic surface of deformed spring (4) matches with trip bolt (5) on being screwed onto handle (1).

2, Door lock handle according to claim 1 and square key assembly structure is characterized in that the elastic surface of deformed spring (4) is a convex surface.
