Abstract
Description
Technical Field
[0001] The utility model belongs to the field of door locks and relates to a positioning device for an anti-locking plate. Technical Background
[0002] Door locks on the market now generally have a lock tongue mechanism and an anti-lock mechanism. The anti-lock mechanism of a general door lock has a relatively simple structure, generally consisting of an anti-lock tongue, an anti-lock plate, and an anti-lock lock cylinder. The shift block of the anti-lock lock cylinder drives the anti-lock plate to move horizontally and pushes the anti-lock tongue out. This anti-lock mechanism achieves positioning through a spring positioning bead, but the spring positioning bead has a high failure rate, and the damping feel is poor, lacking a sense of luxury. Summary of the invention
[0003] In view of the above problems, the utility model provides a positioning device for an anti-locking plate, which has the advantages of good damping feel and low failure rate.
[0004] The purpose of the utility model is achieved in this way:
[0005] A positioning device for an anti-lock plate comprises a door lock body, wherein an anti-lock lock tongue, an anti-lock plate and an anti-lock lock core are arranged in the door lock body, an anti-lock dial block is extended from the anti-lock lock core toward the anti-lock plate, an anti-lock groove matching the anti-lock dial block is formed on the anti-lock plate, an upwardly protruding positioning protrusion is provided on the anti-lock plate, a torsion spring is arranged in the door lock body, a downwardly protruding damping protrusion is formed on the first pressure edge of the torsion spring, the damping protrusion is arranged on the side of the positioning protrusion, and a positioning groove is also formed on the side of the damping protrusion close to the torsion spring.
[0006] The utility model is further configured as follows: the damping protrusion and the positioning groove are connected to form an "N" shape.
[0007] The utility model is further configured as follows: a torsion spring fixing column is formed on the lock shell, the torsion spring is sleeved on the torsion spring fixing column, the second pressing edge of the torsion spring abuts against the lock shell, the first pressing edge of the torsion spring abuts against the anti-locking plate, and the first pressing edge always gives the anti-locking plate a downward pre-tightening force.
[0008] The utility model is further configured as follows: a slide groove is formed on the upper end surface of the anti-locking plate, and the positioning protrusion is arranged in the slide groove.
[0009] The arrangement of the slide groove can prevent the torsion spring and the anti-locking plate from lateral displacement and separation of the torsion spring and the anti-locking plate, thereby reducing the failure rate.
[0010] The utility model is further configured as follows: limiting blocks are formed on the front and rear sides of the anti-locking plate, and limiting grooves matching the limiting blocks are formed on the lock housing.
[0011] By setting the limit block and the limit groove, the lateral movement of the anti-locking plate can be limited, thereby restricting the moving range of the anti-locking plate.
[0012] The utility model is further configured as follows: a restraining end is provided on one side of the anti-locking plate close to the anti-locking bolt.
[0013] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects: through the arrangement of the positioning protrusion, the damping protrusion and the positioning groove, it can not only play a role in positioning the anti-locking plate, but also produce a better damping feel during the movement of the anti-locking plate, and the failure rate is low.
