Abstract

A handle resetting apparatus comprising a handle (1) and a lock body (2), also comprising a spring (3), a limiting cover (4), a first fastener (5), and a second fastener (6). The handle (1) is fitted onto the lock body (2). The spring (3) and the limiting cover (4) are mounted onto the lock body (2) and the handle (1). The first fastener (5) and the second fastener (6) are arranged on the handle (1). Relations of this structural arrangement are utilized to achieve a function for resetting the handle (1).

Description

Handle reset device

Technical field

The utility model relates to a component of a door lock, in particular to a handle reset device.

Background technique

Usually, the door locks and handle reset mechanism parts used by people are numerous and complicated.

technical problem

Technical solution

The purpose of the utility model is to provide a novel handle resetting device, which has the advantages of simple structure, stable and reliable performance, easy production and low cost.

In order to achieve the above object, the technical solution of the present invention is as follows:

A handle resetting device comprising a handle 1 and a lock body 2, characterized in that it further comprises a spring 3, a limit cover 4, and a first fastener 5, the second fastener 6; the handle 1 is fitted on the lock body 2, the spring 3, the limit cover 4 are mounted on the lock body 2 and the handle 1; the first fastener 5, the second fastener 6 Assembled in the handle 1

The handle 1 has a recess 11 , and the limiting cover 4 has a protrusion 41 , and the protrusion 41 of the limiting cover 4 The hook is inserted into the recess 11 of the handle 1 to form a fitting structure of the handle 1 and the limit cover 4;

The spring 3 has a circular shape with an outer end 31 and an inner end 32, and the outer end 31 is disposed on the positioning post 21 of the lock body 2. Upper, inner end 32 is snapped into the recess 11 of the handle 1;

The handle 1 has a card slot 12, and the first fastener 5 is mounted on the card slot 12, and the handle 1 and the spring 3 are The limit cover 4 is fixed on the lock body 2; the second fastener 6 is screwed with the handle 1 to fasten the handle 1 , the spring 3 and the limit cover 4 to the lock body 2 twice.

Handle 1, spring 3, limit cover 4, first fastener 5, second fastener 6 It is a concentric assembly that can be rotated around the same axis.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

As shown in Fig. 1 and Fig. 2, the handle 1 is fitted on the lock body 2, and the outer end 31 of the spring 3 is disposed on the positioning post of the lock body 2 21, the inner end 32 is clamped in the recess 11 of the handle 1, the limit cover 4 is concentrically fitted on the top of the spring 3, and the projection 41 is clamped in the recess 11 of the handle 1, the first retaining wall 42 Abutting the positioning post 21 of the lock body 2, the first retaining wall 42 and the second retaining wall 43 limit the rotation angle of the handle 1, and the handle 1 is rotated by the external force due to the spring 3 and the limit cover 4 There is a fitting structure with a bump and a groove intertwined with the handle 1, so that the rotation of the handle 1 causes the spring 3 to be wound up and stores energy, and the rotation of the handle 1 also drives the following rotation of the limit cover 4, when the handle is 1 When rotated to a certain angle, the second retaining wall 43 of the limit cover 4 will hit the outer end 31 of the spring 3 of the device on the lock body positioning post 21, and the limit cover 4 is blocked and stopped to rotate, the handle 1 Therefore, the rotation is stopped. At this time, the force is released, and the handle 1 is automatically rotated and reset under the resetting force of the spring 3. When the handle 1 is reset, the rotation of the limit cover 4 is reset, and the first block on the limit cover 4 is used. wall 42 When the positioning post 21 on the lock body 2 abuts, the limit cover 4 stops rotating, and the handle 1 is thus stopped, thereby realizing the reset function of the handle 1.

As shown in Fig. 1 and Fig. 2, the first fastener 5 is caught in the slot 12 of the handle 1, and the handle 1 and the spring 3 are attached. The limit cover 4 is fixed on the lock body 2, and the second fastener 6 is fastened on the handle 1 by a secondary fastening handle 1, a spring 3, and a limit cover 4.
