The invention relates to the technical field of fans, in particular to a fan. The fan comprises a shell, an installing frame located in the shell, a first motor installed on the installing frame, a front protective grid installed at the front end of the shell, a back protective grid installed at the back end of the shell, blades, a fixing shaft, a blade frame which is of a hollow structure and a locking mechanism located in the blade frame; the front end of the blade frame is rotatably installed on the front protective grid, and the back end of the blade frame is rotatably installed on the installing frame and connected with an output shaft of the first motor; and the fixing shaft is perpendicularly and rotatably connected to the outer side of the blade frame, one end of the fixing shaft is connected with the blades, and the other end of the fixing shaft penetrates through the interior of the blade frame and is connected with the locking mechanism used for limiting the fixing shaft from rotating. According to the fan, the structure is simple, and the layout is reasonable; and a locking function of the locking mechanism on the fixing shaft only needs to be relieved firstly, then thefixing shaft or the blades are rotated, the angles of the blades can be changed, the fixing shaft is locked through the locking mechanism lastly, and operation is easy and convenient.
Description
technical field [0001] The invention relates to the technical field of fans, in particular to a fan. Background technique [0002] The fan is a device that converts electrical energy into air kinetic energy. It can play the role of cooling, ventilation and exhaust, and is widely used in industry. When the fan is running, the air volume, air pressure and power can be precisely changed by changing the angle of its blades, so it is widely used in the cooling of large equipment. [0003] In the prior art, most of the angles of the fan blades cannot be changed, and only a small part of the fan blades can be adjusted. However, manual disassembly and adjustment are required, which is complicated, time-consuming and labor-intensive. To this end, we propose a fan. Contents of the invention [0004] The main purpose of the present invention is to provide a blower to solve the above-mentioned deficiencies in the background art. [0005] In order to achieve the above object, the pr...
