Hand wheel lock with in-place prompt function

Abstract

The invention discloses a hand wheel lock with an in-place prompt function, and belongs to the field of lock body structures. A driving assembly, a rack assembly and a hand wheel assembly are arranged, wherein lock body units are arranged on two racks in the rack assembly correspondingly, limiting assemblies are correspondingly arranged on the lock body units, the driving assembly can work throughthe rotation of the hand wheel assembly, so that a speed reducing gear can correspondingly drive the two lock body units to get close to each other or far away from each other, then a hand wheel lockcan be opened or locked, the limiting assemblies can enable locking rods to be locked in place or be opened in place, and then corresponding springs drive the racks to impact the speed reducing gear,a mechanical prompt sound is generated for prompting the in place information, and locking or opening of the hand wheel lock is completed. The hand wheel lock is simple in structure and convenient tooperate, forward and reverse torque does not need to be changed in the process of rotating the hand wheel, the opening / locking accuracy, convenience and application comfort of the hand wheel lock areeffectively improved, and good popularization and application values are achieved.

Description

technical field [0001] The invention belongs to the field of lock body structures, in particular to a handwheel lock with a function of prompting in place. Background technique [0002] The handwheel lock is a lock structure that realizes the locking or unlocking of the lock body by rotating the handwheel. It usually controls the movement of the lock tongue by rotating the handwheel in the forward / reverse direction to realize the closing or opening of the lock. Based on the control of the handwheel lock Simple and reliable locking features, widely used in many fields. [0003] In the prior art, it is usually determined whether the handwheel lock is in the open or closed state by manually feeling the rotation resistance of the handwheel lock during the rotation of the handwheel. The judgment basis of human feeling is often whether the handwheel can still be rotated , that is, rotate until the handwheel does not turn; however, the above judgment method often leads to misjudgm...

Problems solved by technology

[0003] In the prior art, it is usually judged whether the handwheel lock has reached the open or closed state by artificially feeling the rotation resistance of the handwheel lock during the rotation of the handwheel. The judgment basis of artificial feeling is often to see whether the handwheel can still rotate , that is, turn until the handwheel does not move; however, the above-mentioned judgment method often leads to misjudgment in some abnormal situations, such as the case of the handwheel lock being locked, so in the actual application of the handwheel lock, in order to ensure that the handwheel To reliably close or open the lock, a large force is usually used in the final stage of rotating the handwheel, which will not only require a large starting force when the handwheel is rotated in the opposite direction next time, causing operation inconvenience, but also to a certain extent It may cause damage to the handwheel lock, affect the normal use of the handwheel lock, and shorten the service life of the handwheel lock
