Stepless locking mechanism

Abstract

The invention provides a stepless locking mechanism which comprises locking blocks, locking roller wheels, a locking mechanism body and springs, wherein taper angles are arranged in inner cavities at the two ends of the locking mechanism body; the locking blocks and the locking roller wheels are arranged in the inner cavities at the two ends of the locking mechanism body; and the springs are arranged between the locking blocks at the two ends of the locking mechanism body. According to the stepless locking mechanism provided by the invention, through the return principle of the springs, the locking blocks are pushed to move towards the two ends of the locking mechanism body along with the locking roller wheels; the taper angles are arranged in the inner cavities at the two ends of the locking mechanism body, and therefore, center distance between the locking roller wheels at the two sides is reduced to implement locking after the locking blocks and the locking roller wheels move towards the two ends of the locking mechanism body. The stepless locking mechanism realizes simple and convenient stepless locking, saves space resources, is small in size, is simple and effective to operate, does not need a special control part, is low in cost, and can be directly operated by maintenance personnel and operating personnel who do not need to be trained.

Description

technical field [0001] The invention relates to a locking mechanism, in particular to a stepless locking mechanism. Background technique [0002] The stepless locking mechanism is a part of general equipment. It is mainly used for frequent linear movement, but is not limited by the moving distance, and the movement is frequent and the installation location is narrow. Therefore, it is generally used for easy operation and variable locking force. On the equipment; this stepless locking mechanism can be widely used in various mechanical equipment in the current market, such as in 3C, shipbuilding, aviation, automobile, railway, mobile crane, upgrading machine and cables, etc., and can be used to lock the guide rail Or guide shaft, the application is basically not affected by the environment, which is convenient for automation, improves reliability, can greatly improve production efficiency, shorten machine adjustment time, and reduce production costs. [0003] However, the ste...

[0003] However, the stepless locking mechanisms in the prior art generally rely on external forces to lock the guide rods and slide rails that need to be moved. The strength of the lock is directly related to the magnitude of the external force, and the structure itself must Reset, if the reset force is too large, it will offset the general locking force, and then the parts that need to be locked may not be firm; if the reset force is small, there will be the disadvantage of being easily stuck, causing it to be unable to move when it needs to be moved

Although the existing stepless locking mechanism can also be automated, the disadvantage is that the mechanism is large and costly, and cannot be adjusted arbitrarily due to the influence of scale or size. It is also necessary to select a suitable motor and corresponding structure according to the required locking force. Therefore, its locking strength and operating environment have a certain limit; and it needs a special control part, so it will further increase the structure, cost, operation difficulty and maintenance cost of the whole machine, and the training requirements for maintenance personnel and operators will increase accordingly
