Abstract

The invention provides a limiting rotating shaft. The limiting rotating shaft comprises a rotating shaft slide block plate, a limiting support block and a supporting base, the rotating shaft slide block plate is provided with a limiting projection, the limiting support block is used to support the rotating shaft slide block plate, the support base is provided with a guide rail groove for accommodating the rotating shaft slide block plate and a limiting block groove for accommodating the limiting support block, the limiting support block supports the rotating shaft slide block plate so that therotating shaft slide block plate slides in the guide rail groove, and the support base is provided with a block in cooperation with the limiting projection on the rotating shaft slide block plate tolimit a rotating shaft. Via the limiting rotating shaft of the invention, a casing is avoided from fracture due to a too large spring force of a present rotating shaft with a spring, and a limiting and fixing effect is provided.

Description

technical field [0001] The invention belongs to the field of connection structures, in particular to a position-limiting rotating shaft. Background technique [0002] The existing rotating shaft is composed of a box, shaft, cam, spring, guide pin and other structures. It connects the flipping structure with the main body and drives through the internal spring and shaft. The product adjusts the spring force to adapt to different torques. need. This type of rotating shaft needs to rely on the spring force to obtain the torsion force, and when the spring force is too large, it is easy to cause the shell to break; during the assembly process, if the rotating shaft is too tightly matched with the flip center shaft, it is easy to cause the flip center shaft to break. After the flip is opened, the angle can continue to increase with force, and no reasonable gear is set to prevent the flip from continuing. Contents of the invention [0003] The technical problem to be solved by ...
