In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The heat dissipation fan installation structure provided by the utility model is preferably implemented as follows Figures 1 to 5 As shown: a heat dissipation fan installation structure, including a chassis plate 1, a ventilation frame 2, the chassis plate 1 is provided with a ventilation hole, the ventilation frame 2 is inserted into the ventilation hole, and a disassembly mechanism 4 is provided between the ventilation frame 2 and the ventilation hole, and a fan 3 is fixedly installed on the inner wall of the ventilation frame 2;

[0025] The disassembly and assembly mechanism 4 includes a block 401, an L-shaped plate 402, and a limit plate 410. The outer side of the chassis plate 1 is connected to the inner wall of the vent and is provided with a slot 406. The block 401 is inserted into the slot 406, and the L-shaped plate 402 is connected to the outer wall of the block 401. A limit rod 403 is fixedly installed on the outer side of the L-shaped plate 402. A groove 405 is provided on the inner wall of the slot 406. The limit rod 403 movably penetrates the inner wall of the groove 405, and a spring 404 is surrounded by the outer wall of the limit rod. The spring 404 is fixedly installed on the L-shaped plate 406. 02 outer side and the inner wall of the groove 405, a contraction groove 407 is provided at the top of the inner wall of the card slot 406, a limit plate 410 is inserted in the contraction groove 407, and the limit plate 410 is clamped on the outside of the clamping block 401, a limit rod 408 is fixedly installed at the top of the inner wall of the contraction groove 407, a rod groove 411 is provided at the top of the limit plate 410, the limit rod 408 is inserted in the rod groove 411, and the outer wall of the limit rod 408 is surrounded by a spring 409, and the spring 409 is fixedly installed between the top of the limit plate 410 and the inner wall of the contraction groove 407.

[0026] Specifically, in the above technical solution, in the initial state, the limit plate 410 shrinks into the shrinkage groove 407, the limit plate 410 compresses the spring 409, and the L-shaped plate 402 blocks the notch of the shrinkage groove 407. When the cooling fan 3 is installed, the ventilation frame 2 is inserted into the ventilation port, so that the card block 401 is inserted into the card slot 406, so that the card block 401 drives the L-shaped plate 402 to move inside the card slot 406, and the L-shaped plate 402 compresses the spring 404. When the card block 401 drives the L-shaped plate 402 to no longer block the notch of the shrinkage groove 407 When the fan 408 is in the closed position, the limit plate 410 is moved out of the contraction groove 407 under the reset force of the spring 2 409, so that the limit plate 410 blocks the block 401, thereby completing the installation of the cooling fan 3. This mechanism can facilitate personnel to disassemble and assemble the cooling fan 3, improve the disassembly and assembly efficiency of personnel, and solve the problem that the cooling fan 3 is installed and fixed by screws in the prior art.

[0030] Among them, by providing the pull rod 412, it is convenient for personnel to pull the limit plate 410 upward through the pull rod 412, thereby facilitating the operation of personnel.
