Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides an embodiment: a fan shell comprises an impeller unit 1 and a shell main body 2, wherein the impeller unit 1 is fixedly arranged inside the shell main body 2, a fixing device 4 is fixedly arranged inside the shell main body 2, a shell 3 is fixedly arranged inside the upper end of the fixing device 4, a pulley groove 5 is formed in the outer surface of the shell 3, a fixing rod 6 is welded inside the shell 3, a fixing support 7 is fixedly arranged on the fixing device 4, a supporting device 8 is connected to the bottom end of the fixing support 7 through threads, a fixing ring 12 is fixedly arranged inside the fixing support 7, a fixing block 11 is welded on the outer surface of the bottom of the fixing ring 12, a threaded sleeve 10 is welded at the bottom end of the fixing block 11, a pulley 9 is fixedly arranged on the inner surface of the fixing ring 12, a threaded rod 16 is fixedly arranged inside the supporting device 8, a handle 13 is welded on, the outer surface of the clamping block 15 is sleeved with a foot pad 14.

First screw hole has been seted up to the side of fixed block 11, and the side of fixed block 11 is rotated and is connected with the screw, and the spacing groove has been seted up on the top of pad foot 14, and the second screw hole has been seted up to the bottom face of threaded sleeve 10, and strutting arrangement 8 passes through threaded rod 16 and threaded sleeve 10 and fixed bolster 7 looks threaded connection, and fixed bolster 7 passes through pulley 9 and pulley groove 5 and casing 3 looks swing joint.

The working principle is as follows: when the machine shell is installed, corresponding adjustment can be correspondingly made according to the installation environment on site, firstly, the height of the supporting device 8 is adjusted according to the height of the machine shell 3 aligned with the installed butt joint port, if the machine shell 3 is lower than the height of the butt joint port, the grip 13 is firstly rotated by external force, the grip 13 is driven by the external force to rotate the threaded rod 16, the threaded rod 16 is rotated to be in threaded rotation with the second threaded hole at the bottom end in the threaded sleeve 10, meanwhile, the fixture block 15 at the bottom end is rotated in the cushion foot 14 when the threaded rod 16 is rotated, so that the interior of the threaded sleeve 10 of the threaded rod 16 extends out, and according to the same operation of the four supporting devices 8, the threaded rod 16 extends downwards, so that the height of the machine shell 3 is increased to the height capable of adapting to the butt joint port, if the height of the machine shell 3 is higher than the height of the butt joint port, the grip 13 is reversely rotated, the length of upper end threaded rod 16, make casing 3 descend to the height of the butt joint mouth of adaptation, thereby be convenient for install, when the inconvenient switch on power supply of turbine unit 1, can rotate the screw of fixed block 11 side, make screw one end keep away from the surface of casing 3, then rotate casing 3 and make the connecting wire of surface rotate the position of conveniently connecting, the pulley 9 of solid fixed ring 12 internal surface can rotate in the inside of pulley groove 5 when casing 3 rotates, thereby improve casing 3 pivoted smoothness nature, pulley 9 also plays the effect of support simultaneously, rotate the screw of fixed block 11 side after the position of casing 3 has been adjusted, make screw one end contact and the extrusion with the surface of casing 3, thereby fix the position of casing 3.
