A continuous locking force device

Abstract

A continuous locking force device comprises a worm gear box, the worm gear is placed in the worm gear box, the worm wheel is sleeved outside the worm gear shaft located in the worm gear box, the two ends of the worm gear shaft protrude from the worm gear box, and a worm gear shaft end located outside the worm gear box There is a rotary lock at the part, and the rotary lock has a locking surface matched with the locked body. Both ends of the worm stick out of the worm gear box. The worm gear includes a worm gear body, a torsion spring, and a limit pin. A combined rotary structure with a cavity is formed. The axis of the limit pin is parallel to the shaft of the worm wheel. The lower end of the limit pin is fixed on the main worm wheel, and the upper end of the limit pin is placed in the long circular arc hole on the auxiliary worm wheel. The torsion spring located in the cavity G There are one torsion arm and two torsion arms, the first torsion arm of the torsion spring is inserted on the auxiliary worm gear, and the second torsion arm of the torsion spring is inserted into the main worm gear. The invention does not increase the space of the locking mechanism, uses the torque generated by the torsion spring to act on the locked box, eliminates the vibration of the locked box during transportation, and protects the locking mechanism from damage.

Description

technical field [0001] The invention belongs to the technical field of box body locking, and relates to a device that can provide a continuous locking force for a locked box body without increasing the space size of the mechanism. Background technique [0002] During transportation, especially in the complex terrain of mountainous and hilly environments, vibration occurs due to uneven roads. On the one hand, there is a certain machining error in the machined structure of the locking mechanism itself. Therefore, in the locked state, the components of the locking mechanism are in the locked state. There is a certain gap, and vibration will be generated during transportation. This vibration will have a certain impact on the locking mechanism, cause damage to the locking mechanism, and affect the service life of the locking mechanism. The existence of gaps between the locking bodies can also result in failure to lock, which in turn causes the locking mechanism to use a consumabl...

Problems solved by technology

[0002] In the process of transportation, especially in the complex terrain of mountainous and hilly environments, vibrations are generated due to uneven roads. On the one hand, there are certain processing errors in the mechanical structure of the locking mechanism itself. There is a certain gap, and vibration will be generated during transportation. This vibration will have a certain impact on the locking mechanism, and will cause damage to the locking mechanism, which will affect the service life of the locking mechanism; The presence of gaps between the locking bodies can also prevent locking, which in turn makes the locking mechanism use a fragile ring in a vibrating environment

How to design a locking device to solve the problem of vibration of the locked body and avoid damage to the locking mechanism has become an urgent problem to be solved
