Description

Centrifugal fan of convenient dismouting protection network Technical Field The utility model belongs to the technical field of fans, relates to a centrifugal fan, and particularly relates to a centrifugal fan with a protective net convenient to assemble and disassemble. Background The fan is a machine which increases the pressure of gas and discharges the gas by means of input mechanical energy, is a driven fluid machine, and is widely applied to various fields at present. Because the protection network of fan air intake uses in-process very easily deposition, needs frequent washing, if damage takes place, still needs to change, current fan air intake protection network all is through a plurality of fixing bolt connection on the casing, leads to dismantling time and energy, leads to later maintenance inconvenient, delays work efficiency, has not satisfied the production demand of enterprise. Disclosure of Invention The utility model aims to solve the problems in the prior art and provides a centrifugal fan with a protective net convenient to assemble and disassemble, and convenient to maintain. The centrifugal fan is characterized in that the protection net is arranged at the air inlet, a first connecting part is arranged at the air inlet, a second connecting part matched with the first connecting part is arranged on the protection net, a clamping mechanism is arranged on the inner wall of the first connecting part, a movable space for the clamping mechanism to move is formed in the first connecting part, the clamping mechanism comprises a clamping spring and a clamping block, a clamping part matched with the clamping block is arranged at the upper end of the second connecting part, and an unlocking piece is movably arranged between the first connecting part and the second connecting part. In the centrifugal fan with the protective net convenient to assemble and disassemble, the limiting part for limiting the second connecting part is arranged on the inner wall of the first connecting part. In the centrifugal fan with the protective net convenient to assemble and disassemble, the clamping block is provided with the guide part for conveniently unlocking the extrusion of the piece. Compared with the prior art, the fan and the protective net can be connected quickly through the matching of the clamping mechanism and the clamping part, the process of slowly installing bolts one by one is reduced, the fan and the protective net can be separated quickly through the unlocking piece, the time of later disassembly, assembly and maintenance is reduced, and the use experience of a customer is improved.

Fig. 3 is a schematic view of a partial enlarged structure at a of the present utility model. In the figure, 1, an air outlet, 2, an air inlet, 3, a fan main body, 4, a protective net, 5, a first connecting part, 6, a second connecting part, 7, a clamping mechanism, 8, a movable space, 9, a clamping spring, 10, a clamping block, 11, a clamping part, 12, an unlocking piece, 13, a limiting part, 14, a guiding part and 15, and a driving motor. Detailed Description The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments. As shown in fig. 1, the centrifugal fan with the protection net 4 convenient to disassemble and assemble comprises a fan main body 3 with an air outlet 1 and an air inlet 2 and a driving motor 15, the protection net 4 is arranged at the air inlet 2, a first connecting part 5 is arranged at the air inlet 2, a second connecting part 6 matched with the first connecting part 5 is arranged on the protection net 4, a clamping mechanism 7 is arranged on the inner wall of the first connecting part 5, a movable space 8 for the clamping mechanism 7 to move is formed in the first connecting part 5, the clamping mechanism 7 comprises a clamping spring 9 and a clamping block 10, a clamping part 11 matched with the clamping block 10 is arranged at the upper end of the second connecting part 6, and an unlocking part 12 is movably arranged between the first connecting part 5 and the second connecting part 6.
