[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The embodiment of the present application provides a cooling fan splicing structure to solve the problem that the traditional cooling fan splicing structure usually combines the outer frames and fixes them at multiple points with screws. During actual use, this splicing method requires the use of external tools such as screwdrivers, which is cumbersome to operate. In addition, the fans are connected by wires, which are easily messy when exposed, and the interface positions are not stored and protected, resulting in poor stability.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model embodiment discloses a heat dissipation fan splicing structure, according to the attached Figure 1-6 As shown, it includes more than two groups of cooling fan bodies 1, and adjacent cooling fan bodies 1 are connected by splicing clamps 2. Clamping grooves 101 are provided on opposite sides of the cooling fan bodies 1. Both ends of the splicing clamps 2 are respectively clamped with the clamping grooves 101 of two adjacent cooling fans. When one end of the splicing clamp 2 is clamped with one of the clamping grooves 101, the other end can rotate with the clamping point as the axis and clamp with the other clamping groove 101.

[0026] Furthermore, the inner wall of the snap-in groove 101 is provided with a circular locking groove 1011, and the splicing card 2 is provided with a snap-in ear extending to one side of the snap-in groove 101, and the end of the snap-in ear is provided with a snap block 201 corresponding to the locking groove 1011. When the snap block 201 at one end of the splicing card 2 is snapped in the locking groove 1011, the other end can rotate around the snap-in point as the axis. With the circular snap block 201 design, when the splicing card 2 is snapped in the locking groove 1011 of the cooling fan body 1, the splicing card 2 itself can rotate, which is convenient for snapping the second group of cooling fan bodies 1.

[0027] Furthermore, a wiring groove 104 for wiring is provided between the clamping grooves 101 on opposite sides of the heat dissipation fan body 1 , and two adjacent heat dissipation fan bodies 1 are electrically connected via wires, and the connection terminals of the wires are placed at the clamping grooves 101 .

[0028] Furthermore, a positioning column 102 is fixedly connected to the inside of the snap-in groove 101, and an arc-shaped positioning notch 202 is provided on the splicing card 2. When the cooling fan body 1 and the splicing card 2 are snapped together, the positioning column 102 and the arc-shaped positioning notch 202 are engaged. The positioning column 102 and the arc-shaped positioning notch 202 cooperate with each other, so that the connection position between the cooling fan body 1 and the splicing card 2 is positioned during the snap-in process, thereby ensuring that the snap-in position is accurate and the splicing structure is stable.

[0029] Furthermore, a terminal slot 103 for routing wires and connection terminals is provided on the cooling fan body 1, and the wiring slot 104 and the terminal slot 103 are designed to facilitate routing of wires and connection terminals.

[0030] The space formed between the snap-in slot 101 and the splicing card 2 is used to store the wiring terminals. The wiring terminal snap-in slot 103 is connected to the snap-in slot 101. Through the space design formed between the wiring terminal snap-in slot 103, the snap-in slot 101 and the splicing card 2, the wiring terminals are easy to store, the terminals and cables are protected, and the stability is good.

[0031] The heat dissipation fan splicing structure facilitates the rapid splicing of multiple groups of heat dissipation fan bodies 1. When splicing, the two groups of heat dissipation fan bodies 1 are aligned, and then the splicing clamp 2 is aligned with the inside of the clamping grooves 101 of the two groups of heat dissipation fan bodies 1 and clamped, so that the clamp block 201 is clamped inside the clamping groove 101 and then clamped in the locking groove 1011 to form a limit, and finally the arc-shaped positioning notch 202 is fitted with the positioning column 102, and the positioning column 102 is used to realize the limit of the splicing clamp 2;

[0032] During the process of using the splicing clamp 2 for connection, the design of the wiring groove 104 and the terminal clamping groove 103 facilitates the lead-out connection of the connecting wires and the connecting terminals inside the cooling fan body 1. After the two sets of cooling fan bodies 1 are electrically connected, the connecting terminals can be conveniently stored inside the clamping groove 101, making the cooling fan body 1 beautiful and convenient for subsequent inspection and maintenance.

[0033] The cooling fan splicing structure adopts the design of the snap-in groove 101, the locking groove 1011 and the splicing clamp 2, which facilitates the rapid snap-in connection of multiple cooling fan bodies 1 without the use of external tools such as screwdrivers. Combined with the design of the terminal slot 103, multiple cooling fan bodies 1 can be easily connected through wires and terminal blocks. After the connection, the terminals can be easily stored, making the spliced ​​cooling fan bodies 1 beautiful and easy to inspect and maintain later.
