Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a novel quickly detachable fan. Background Art

[0002] A fan is a machine that relies on input electrical energy to increase gas pressure and discharge gas. It is a driven fluid machine.

[0003] Currently available fans generally include a fan body and a protective cover arranged on the front side of the fan body. The protective cover and the fan body are fixed by multiple bolts. When the fan needs to be disassembled and installed, the multiple bolts need to be removed one by one, and when installing, the multiple bolts also need to be installed one by one. The overall installation and disassembly process is relatively cumbersome. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the utility model provides a novel quickly detachable fan, which solves the problems raised by the background technology.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of quickly detachable fan, comprising a fan body, a protective device is arranged at the front end of the fan body, the protective device comprises an annular frame and a protective net arranged in the annular frame, a through hole is opened on the annular frame, a connecting component is connected to the bolt hole, and the protective device is connected to the fan body through the connecting component.

[0008] Preferably, the connecting assembly includes a bolt body, a clearance groove is opened at the upper end of the bolt body, a rotating rod is arranged in the clearance groove, a rotating shaft is passed through the rotating rod, and both ends of the rotating shaft are fixedly connected to the two side walls of the clearance groove respectively.

[0009] Preferably, the surface of the upper rod section of the bolt body is smooth, and the surface of the lower rod section of the bolt body is threaded.

[0010] Preferably, a bolt hole is provided on the fan body at a position corresponding to the through hole, and the bolt hole matches the threaded body.

[0011] Preferably, the length of the rotating rod is greater than the diameter of the through hole.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. For this new type of quickly detachable fan, by setting up a connection component, when disassembling, when the connection component is rotated to a certain extent, rotate the rotating rod so that the rotating rod is parallel to the bolt body. At this time, pulling the protection device can achieve the separation between the protection device and the fan main body without completely removing the bolts. At the same time, since the connection component is small in volume, it will not be lost. During installation, insert the through hole on the protection device corresponding to the connection component again, then rotate the rotating rod so that the rotating rod is perpendicular to the bolt body, and then rotate the rotating rod so that the rotating rod is tightly pressed against the surface of the protection device to achieve the quick installation between the protection device and the fan main body.
