[0020] As Figure 1 shown, the present disclosure provides a fan test fixture including a bracket 10 and a fan base 20 disposed on the bracket 10. Above the fan base 20, there is a cover plate assembly 30 for fixing the fan;

[0021] Among them, a through groove matching the fan base 20 is provided on the bracket 10, and a braking component 40 is provided at the bottom of the bracket 10. The braking component 40 can pass through the through groove and act on the fan on the fan base 20, so that the fan stops rotating, simulating the scenario where the fan fails and stops.

[0022] The technical solution of this application is to set a braking component on the bracket in cooperation with the fan base. When testing a fan with a fault feedback signal, the fan can be quickly braked through the braking component, with simple operation, high efficiency and safety and reliability.

[0023] In some embodiments, the braking component 40 includes a braking paddle 41, a braking shaft 42 and a braking rod 43; one end of the braking paddle 41 is rotatably installed on the bracket 10, and the other end is sleeved on the braking shaft 42, and the braking rod 43 is fixed to the braking paddle 41; when the braking paddle 41 is toggled upward, when the braking paddle 41 moves along the braking shaft 42, it drives the braking rod 43 to move towards the fan, so that the braking rod 43 is placed between the fan blades, thereby braking the fan. Preferably, as Figure 2 shown, a limiting rod can be provided on one side of the braking shaft 42 to prevent the braking paddle 41 from being toggled too much and the braking rod 43 from damaging the fan.

[0024] In this embodiment, as Figure 2 shown, at least two braking rods 43 are provided, an adjustment groove 411 is provided on the braking paddle 41, and the braking rod 43 is detachably fixed in the adjustment groove 411. Specifically, the braking rod 43 can be detachably fixed in the adjustment groove 411 by means of threaded cooperation.

[0025] Preferably, a soft silicone is provided at the top of the braking rod 43. The top of the braking rod 43 is made of wear-resistant soft silicone material to quickly brake the center point of the fan without damaging the fan.

[0026] In some embodiments, as Figure 1 and Figure 3 shown, the cover plate assembly 30 includes an upper cover 31 and a fixing rod 32 provided on the upper cover 31. One end of the upper cover 31 is rotatably installed on the bracket 10, and the other end is connected to the bracket 10 through a snap self-locking device 50. The fixing rod 32 is used to fix the fan in the fan base 20.
