[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a fire cabinet type centrifugal fan which is easy to install.

[0025] The utility model provides Figure 1-3 The fire cabinet-type centrifugal fan shown is easy to install, including a base 1 and a body 2. The body 2 is arranged on the top of the base 1. Two clamping components 3 are symmetrically arranged above the base 1. A connecting mechanism is arranged between each clamping component 3 and the base 1, and they are respectively connected to the base 1 through corresponding connecting mechanisms. A synchronous tensioning mechanism is arranged inside the base 1. The synchronous tensioning mechanism includes a rotating rod 4, a winding wheel 5 and two traction ropes 6. The rotating rod 4 is rotatably arranged inside the base 1 and fixedly sleeved with the winding wheel 5. Both ends of each traction rope 6 are fixedly connected to the inner wall of the winding wheel 5 and the corresponding clamping component 3. By utilizing the arranged rotating rod 4 and winding wheel 5, the winding wheel 5 can be driven to realize the winding and releasing of the two traction ropes 6 during the rotation of the rotating rod 4, so that the traction rope 6 can be tightened or loosened during the rotation of the winding wheel 5, which effectively simplifies the disassembly and assembly process of the body 2.

[0026] like Figure 3 As shown, the connecting mechanism includes a slider 7 and two U-shaped rods 8. The slider 7 is fixedly arranged at the bottom of the corresponding clamping assembly 3 and is movably connected with the rod walls of the two U-shaped rods 8. The two U-shaped rods 8 are fixedly arranged on the upper surface of the base 1. By utilizing the set connecting mechanism, the connection between the clamping assembly 3 and the base 1 can be achieved, and the position of the clamping assembly 3 can be adjusted while avoiding the separation of the clamping assembly 3 and the base 1.

[0027] like Figure 2As shown, a worm wheel 9 is fixedly sleeved on the rod wall of the rotating rod 4, and a worm 10 is meshingly connected to the side wall of the worm wheel 9. Both end rod walls of the worm 10 are rotatably connected to mounting plates 11 fixedly connected to the top inner wall of the base 1. By using the two mounting plates 11, the position of the worm 10 can be fixed. Through the meshing connection between the worm 10 and the worm wheel 9, the worm wheel 9 can be driven to rotate during the rotation of the worm 10, thereby realizing the driving of the synchronous tensioning mechanism.

[0028] like Figure 1 As shown, two U-shaped plates 12 are symmetrically fixedly provided on the top inner wall of the base 1, and a rotating shaft 13 is rotatably sleeved inside each U-shaped plate 12. A guide wheel 14 is fixedly sleeved on the rod wall of each rotating shaft 13, and the two traction ropes 6 are respectively matched with the corresponding guide wheels 14. The two guide wheels 14 are provided to guide the corresponding traction ropes 6, so that the two traction ropes 6 can be kept perpendicular to the shaft pin of the winding wheel 5, thereby ensuring the normal winding process of the winding wheel 5.

[0029] like Figure 1 As shown, two strip openings are symmetrically opened on the top of the base 1, and the two traction ropes 6 are movably passed through the corresponding strip openings. The two strip openings can ensure the normal installation of the two traction ropes 6 and the normal use of the two traction ropes 6.

[0030] like Figure 2 As shown, one end of the worm 10 passes through the corresponding mounting plate 11 and is fixedly connected to a crank 15. The crank 15 can be used to drive the worm 10 to rotate, thereby driving the worm wheel 9 and the rotating rod 4.
