DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Please refer to Figures 1-6 The utility model provides a kind of technical scheme: a cold fan with upper cover plate body positioning connection structure, including cold fan body 1, the upper surface of cold fan body 1 is equipped with the positioning assembly for realizing quick positioning, the top of cold fan body 1 is equipped with the cover plate assembly for increasing overall stability, the surface of cover plate assembly is equipped with the convenient assembly for improving overhaul cleaning efficiency.

[0024] Positioning assembly includes vertical clamping groove 2, vertical clamping groove 2 is opened in the upper surface of cold fan body 1, the inner wall of vertical clamping groove 2 is equipped with rubber buffer pad 3.

[0025] Horizontal clamping groove 4 is opened in the side of cold fan body 1 upper surface close to vertical clamping groove 2, L-shaped positioning groove 5 is opened in the both ends of horizontal clamping groove 4 inner wall, rotating piece 6 is rotatably installed in the both sides of L-shaped positioning groove 5 inner wall, pressing plate 7 is installed on the surface of rotating piece 6, and the surface of pressing plate 7 is slidably connected with the inner wall of L-shaped positioning groove 5.

[0026] Clamping plate 9 is installed on the side of rotating piece 6 close to pressing plate 7, the surface of clamping plate 9 is slidably connected with the both sides of L-shaped positioning groove 5 inner wall, and elastic rubber pad 10 is installed on the side of the surface of clamping plate 9.

[0027] The cover plate assembly comprises an upper cover plate frame 11, the bottom of the upper cover plate frame 11 is connected with the top of the cooling fan body 1, a first sealing layer 12 is installed at the connecting position of the upper cover plate frame 11 and the cooling fan body 1, an L-shaped connecting piece 13 is installed on the lower surface of the upper cover plate frame 11, the horizontal part of the L-shaped connecting piece 13 is connected with the lower surface of the upper cover plate frame 11, and screws 14 are installed at both ends of the lower surface of the horizontal part of the L-shaped connecting piece 13 and penetrate the L-shaped connecting piece 13 and are connected with the upper cover plate frame 11. The screws 14 penetrate the L-shaped connecting piece 13 and are tightly connected with the upper cover plate frame 11, thereby ensuring the stable connection between the upper cover plate frame 11 and the cooling fan body 1, enhancing the structural strength of the entire upper cover plate and preventing the upper cover plate from shaking or falling off during use.

[0028] Specifically, the vertical part of the L-shaped connecting piece 13 matches the vertical clamping groove 2, and the horizontal part of the L-shaped connecting piece 13 matches the horizontal clamping groove 4. When the upper cover plate frame 11 is installed on the top of the cooling fan body 1, the vertical part of the L-shaped connecting piece 13 enters the vertical clamping groove 2 first and is connected with the rubber buffer pad 3 inside the vertical clamping groove 2. By installing the rubber buffer pad 3, the damage to the components caused by the collision can be reduced, and the friction between the vertical part and the vertical clamping groove 2 can be increased, so that the preliminary positioning is more stable, and the upper cover plate frame 11 is prevented from moving accidentally before being completely fixed. At this time, the upper cover plate frame 11 is pressed downward, so that the L-shaped connecting piece 13 moves downward, and the horizontal part of the L-shaped connecting piece 13 slides into the horizontal clamping groove 4. At this time, the horizontal part of the L-shaped connecting piece 13 presses the pressing plate 7 into the horizontal part of the L-shaped positioning groove 5, thereby driving the rotating piece 6 to rotate by a certain angle, driving the clamping plate 9 and the elastic rubber pad 10 on the surface of the clamping plate 9 to clamp and fix the L-shaped connecting piece 13, thereby optimizing the fixing effect and stability of the upper cover plate and reducing the wear and collision between the components, thereby providing a strong guarantee for the stable operation of the cooling fan.

The bearing groove 15 provides a stable mounting position for the cover plate body 18, so that the cover plate body 18 can be firmly mounted on the inner side of the upper cover plate frame 11 of the cooling fan.

[0030] One end inside the bearing groove 15 is provided with a rotating shaft 17, the surface of the rotating shaft 17 is provided with a cover plate body 18, one side of the lower surface of the cover plate body 18 is provided with a second magnetic attraction piece 19, the upper surface of the cover plate body 18 is provided with a clamping cover 20, the surface of the cover plate body 18 is connected with the inner wall of the bearing groove 15, the surface connection of the cover plate body 18 and the bearing groove 15 is provided with a second sealing layer 21. By pulling the clamping cover 20, the cover plate body 18 can be driven to rotate around the rotating shaft 17, so as to facilitate the maintenance or cleaning of the cooling fan, when the cover plate body 18 is rotated to the closed position, the first magnetic attraction piece 16 and the second magnetic attraction piece 19 will attract each other, this magnetic connection not only ensures that the cover plate body 18 can be tightly attached to the bearing groove 15, prevents it from being opened accidentally, but also provides additional stability, enhances the overall structural strength of the cooling fan; through the cooperation of the first sealing layer 12 and the second sealing layer 21, it can effectively prevent external dust, moisture and other impurities from entering the inside of the cooling fan, protect the internal components from damage, at the same time, it can also ensure that the air flow inside the cooling fan does not leak when running, maintain the cooling and air supply effect of the cooling fan.
