Description

Lock box buffer sheet

Technical Field

The utility model relates to the technical field of lock boxes, in particular to a lock box buffer plate.

Background

At present, when a door is opened and closed, a conventional lock body has the action of extending and retracting a lock tongue, and the lock tongue extends under the drive of a spring or a torsion spring to impact a lock body guide plate so as to generate noise.

Disclosure of Invention

In order to solve the technical problems, the utility model aims to provide a lock box buffer sheet so as to solve the technical problems in the prior art.

The utility model provides a lock box buffer piece, includes lock body guide piece, spring bolt, spring and buffer spring leaf, the spring is installed in spring bolt one end, buffer spring leaf is installed on the spring bolt, be equipped with spring leaf body, buffer piece and spring bolt hole on the buffer spring leaf, the spring leaf body is the lamellar, the spring bolt hole is seted up at spring leaf body geometric center, buffer piece one end and spring leaf body coupling.

Still further, the buffer piece is lamellar, buffer piece connection spring leaf body one end protrusion, buffer piece one end is equipped with the buffer with the spring leaf body, and this buffer is spring leaf body and buffer piece for in-service use in-process, produces deformation easily at spring bolt and lock body guide piece striking in-process, sets up the buffer and can effectively reduce deformation.

Compared with the prior art, the utility model has the beneficial effects that; the buffer spring piece is arranged between the lock tongue and the lock body guide piece, so that the impact sound between the lock tongue and the lock body guide piece is effectively reduced.

The foregoing description is only an overview of the present utility model, and is intended to provide a better understanding of the present utility model, as it is embodied in the following description, with reference to the preferred embodiments of the present utility model and the accompanying drawings.

Detailed Description

The following describes in further detail the embodiments of the present utility model with reference to the drawings and examples. The following examples are illustrative of the utility model and are not intended to limit the scope of the utility model.

As shown in fig. 1 to 3, a lock box buffer sheet comprises a lock body guide sheet 1, a lock tongue 2, a spring 3 and a buffer spring piece 4, wherein the spring 3 is arranged at one end of the lock tongue 2, the buffer spring piece 4 is arranged on the lock tongue 2, a spring piece body 41, a buffer sheet 42 and a spring tongue hole 43 are arranged on the buffer spring piece 4, the spring piece body 41 is in a sheet shape, the spring tongue hole 43 is formed in the geometric center of the spring piece body 41, one end of the buffer sheet 42 is connected with the spring piece body 41, as shown in fig. 1, the lock tongue 2 passes through the spring tongue hole 43 of the buffer sheet 4 and the lock body guide sheet 1, the spring 4 arranged on the lock tongue 2 applies pretightening force to the shown side, the hole on the lock body guide sheet 1 is opposite to the lock tongue 2, the spring 4 force passes through the lock body guide sheet 1, and the impact force is reduced and unlocking noise is reduced due to the fact that the lock tongue 2 passes through the buffer spring piece 4.

Preferably, as shown in fig. 2, the buffer sheet 42 is in a sheet shape, one end of the buffer sheet 42 connected with the spring leaf body 41 is protruded, one end of the buffer sheet 42 and the spring leaf body 41 are provided with a buffer area 44, the buffer area 44 is formed by the spring leaf body 41 and the buffer sheet 42 in the actual use process, two ends of the buffer sheet are bent as shown in fig. 3, the elasticity of the buffer sheet 42 is increased, deformation is easily generated in the impact process of the lock tongue 2 and the lock body guide sheet 1, and the buffer area is arranged to effectively reduce the deformation.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and it should be noted that it is possible for those skilled in the art to make several improvements and modifications without departing from the technical principle of the present utility model, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
