[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a cooling fan for ultra-thin laptops, comprising: a bottom shell 1; a top shell 2 mounted on the top of the bottom shell 1; a metal spring 15 fixedly connected to the bottom of the top shell 2, with a beveled locking block 16 fixedly connected to the inner side of the metal spring 15; a side groove 19 opened on one side of the bottom shell 1, with a limiting groove 18 inside the side groove 19 that cooperates with the beveled locking block 16; a fixing screw 8 fixedly connected to the top of the bottom shell 1; and an internally threaded cylinder 10 rotatably disposed inside the top shell 2, the internally threaded cylinder 10 cooperating with the fixing screw 8.

[0025] It is understood that, in this utility model, during the splicing and installation between the top shell 2 and the bottom shell 1, the sealing frame 6 and the sealing groove 7 are positioned and installed. The fixing screw 8 enters the inner side of the internal threaded cylinder 10 and rotates by the external rotating sleeve 12. When the external rotating sleeve 12 rotates, it drives the inner internal threaded cylinder 10 to rotate. The inner side of the internal threaded cylinder 10 is threadedly installed with the outer thread of the fixing screw 8. The internal threaded cylinder 10 drives the outer limiting ring 11 to rotate within the top shell 2. When the internal threaded cylinder 10 moves and adjusts outside the fixing screw 8, the positioning strip 13 is simultaneously positioned and installed with the positioning groove 14. On the other side... The metal spring 15 and the inclined plate 16 enter the side groove 19. The inclined plate of the inclined plate 16 presses against the side groove 19, and the side groove 19 pushes the inclined plate 16, causing the metal spring 15 to deform. When the inclined plate 16 reaches one side of the limiting groove 18, the metal spring 15 resets and drives the inclined plate 16 to reset. The reset of the inclined plate 16 drives the inclined plate 16 to enter the limiting groove 18. At this time, the internal threaded cylinder 10 is also fixed in place on the outside of the fixing screw 8. The sealing frame 6 at the bottom of the top shell 2 enters the sealing groove 7 at the top of the bottom shell 1, which stably fixes the top shell 2 and the bottom shell 1, improving the stability of the fixation after splicing.

[0026] Please see Figures 1 to 5 It also includes a support base 4, which is fixed to the inside of the bottom shell 1. A fan 5 is installed on the top of the support base 4, and a connecting wire 9 is provided on one side of the fan 5.

[0027] It is understood that this utility model supports the fan 5 through the support base 4 and uses the fan 5 for heat dissipation.

[0028] Please see Figures 2 to 4The bottom of the top shell 2 is symmetrically fixed with positioning strips 13, and the top of the bottom shell 1 is symmetrically provided with positioning grooves 14 that cooperate with the positioning strips 13.

[0029] It is understood that this utility model uses the positioning strip 13 at the bottom of the top shell 2 and the positioning groove 14 at the top of the bottom shell 1 to limit the splicing and installation between the bottom shell 1 and the top shell 2.

[0030] Please see Figure 2 and Figure 5 An outer limiting ring 11 is fixedly connected to the outer side of the internal threaded cylinder 10. The outer limiting ring 11 is rotatably connected to the top shell 2. An outer rotating screw sleeve 12 is fixedly connected to the outer side of the internal threaded cylinder 10.

[0031] It is understood that the present invention drives the internal threaded cylinder 10 to rotate through the outer rotating sleeve 12 fixed on the outside of the internal threaded cylinder 10, which facilitates the installation of the internal threaded cylinder 10 on the outer thread of the fixed screw 8. When the internal threaded cylinder 10 rotates, it drives the outer limiting ring 11 to rotate within the top shell 2 to limit the rotation of the internal threaded cylinder 10.

[0032] Please see Figure 4 A pull block 17 is fixed to the side of the metal spring 15 away from the inclined block 16.

[0033] It is understood that in this utility model, the metal spring 15 is pulled by the pull block 17, and the deformation of the metal spring 15 causes the pull block 17 to move away from the limiting fixation between it and the limiting slot 18.

[0034] Please see Figures 1 to 5 The bottom of the top shell 2 is fixedly connected to a sealing frame 6, and the top of the bottom shell 1 is provided with a sealing groove 7 that matches the sealing frame 6. Both the bottom shell 1 and the top shell 2 are provided with an air outlet 3 on one side.

[0035] It is understood that this utility model improves the connection stability between the bottom shell 1 and the top shell 2 by cooperating and sealing the sealing frame 6 at the bottom of the top shell 2 with the sealing groove 7 at the top of the bottom shell 1.

[0036] In the description of this utility model, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "other end", "upper", "side", "top", "inner", "front", "center", "both ends", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.
