Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

With reference to fig. 1 to 11, the embodiment of a locking device is schematically shown in a structural diagram, and includes a housing 1 for receiving and mounting, a lock wheel 2 is rotatably disposed in the housing 1, a lock sleeve 3 is fixedly connected to the lock wheel 2, a lock clip 4 capable of locking the lock sleeve 3 is disposed on the lock sleeve 3, one end of the lock clip 4 is movably mounted on a lock column 8 through an elastic body 7, the other end of the lock clip is movably connected to a rail groove of a lock rail 5, the lock rail 5 can linearly slide and passes through the lock groove 6 to be connected to an external traction device, the lock groove 6 is fixedly connected to the housing 1, the lock rail 5 linearly slides in the lock groove 6 through pulling and pushing actions of the traction device, and the rail groove of the lock rail 5 drives the lock clip 4 to move the lock clip 3 inward; the lock clips 4 are a pair and symmetrically arranged at two sides of the periphery of the lock sleeve 3; a meshing pair is arranged between the lock clamp 4 and the lock sleeve 3; the elastic body 7 is a torsion spring, one end of the torsion spring leans against the stop column 9 which is connected with the shell 1 into a whole, and the other end of the torsion spring is hung against the locking clamp 4; the rail groove of the lock rail 5 is provided with a dead point position, when the rail groove at the position is completely meshed with the other end of the lock clamp 4, the lock clamp 4 is locked, and the lock clamp 4 is locked with the lock sleeve 3.
