Abstract

The invention provides a draught fan system and a locking device of the draught fan system. The locking device comprises a body, a locking piece and an operating piece, wherein the body is provided with a containing cavity, the side wall of the body is provided with a hole, the locking piece is flexibly arranged in the hole of the body, the operating piece is detachably connected with the body, an axial positioning structure is arranged between the operating piece and the body, one end of the operating piece is inserted into the containing cavity, and the locking piece extrudes from the outside of the body under the function of one end of the operating piece. The locking device has the advantages of being convenient to disassemble and install, is not limited by installation tools, can lock objects easily, and can greatly reduce the difficulty of locking when the objects are locked in a narrow and small space. Moreover, by adoption of the locking device, threads need not processing, so that the process of locking is reduced, the problem that thread holes are difficult to be processed in a narrow space is solved, and the locking efficiency is improved.

Description

technical field [0001] The invention relates to the field of positioning adjustment, and more specifically, to a fan system and a locking device thereof. Background technique [0002] In the prior art, screws are generally used to lock and position objects in a narrow space. However, due to the limitation of space and installation tools, the installation and removal of screws are usually difficult to achieve; in addition, positioning with screws sometimes requires machining It is very difficult to complete this process in a small space to produce threaded holes for screws to pass through. For example, when using screws to lock and position the motor shaft in the hub in the fan system, since the hub is located in a small space in the fan system, it will be difficult to install and remove the screws. At the same time, on the hub It is also difficult to process threaded holes for screws to pass through. Contents of the invention [0003] The present invention aims to provid...
