Embodiment one:

Embodiment 1 of the present invention, as shown in Figure 1, is a fan that can be quickly replaced without tools, including a fan blade 101 and a fan frame 102. On the supporting frame 20 outside the fan blade 101 , the outer walls of the left and right sides of the supporting frame 20 are provided with elastic handles 201 correspondingly near the top wall, and the outer walls of the elastic handle 201 are provided with engaging mechanisms 202 .

The elastic portable device 201 plays the role of pressing the engaging mechanism 202 to disengage, and also plays the role of the operator holding the fan tightly. The engaging mechanism 202 plays the role of directly clamping the fan to the box where the fan is installed in the server. Function, in general, the structure used to install the fan, such as the box for installing the fan in the server, such as the fan cover, needs to be provided with an engaging hole for the engaging mechanism 202, as shown in Figure 3 and Figure 4, when When the fan needs to be replaced, one only needs to hold the elastic portable device 201 by hand and apply a certain pressure to disengage the engaging mechanism 202, lift the fan, and then the fan can be taken out from the box where the fan is installed in the server, which is convenient for electronic equipment. The fan is taken and installed during operation, the operation is convenient and fast, and the fan is not easy to be damaged, and has a good use effect.

It should be noted that, in Embodiment 1 of the present invention, as shown in FIG. The device 201 and the support frame 20 can also be arranged in a detachable structure, such as connecting the elastic hand-held device 201 and the support frame 20 through threaded connection, clamping, etc., which is not specifically limited here.

Further, as shown in FIG. 1 in Embodiment 1 of the present invention, the engaging mechanism 202 is arranged on the outer wall of the elastic handle device 201 on the right side wall of the support frame 20; in other embodiments, the engaging mechanism 202 can also be provided with On the outer wall of the elastic portable device 201 on the right side wall of the support frame 20, and on the outer wall of the elastic portable device 201 on the left side wall of the support frame 20, it can be selected according to the equipment space and installation requirements during actual use, here Not specifically limited.

Further, as shown in Figure 1 and Figure 2 in Embodiment 1 of the present invention, the elastic carrying device 201 is set as a handle extending upward from the side wall of the support frame 20 and bent toward the top wall of the support frame 20, specifically, the handle It can be set in an L shape, and the long side and the short side of the L-shaped handle are connected to each other to form an angled opening facing the direction where the fan blade 101 is located. As shown in Figures 1 and 2, the left side wall of the support frame 20 and the The direction of the opening of the handle of the elastic handle device 201 on the right side wall is corresponding.

Further, as shown in Figure 1 and Figure 2 in Embodiment 1 of the present invention, the shape of the support frame 20 is a rectangle, and the diagonal position between the side wall and the top wall connected to the support frame 20 is correspondingly opened for accommodating the elastic handle. The device 201 elastically deforms the first card slot, the bottom of the first card slot extends from the side wall of the support frame 20 to the top wall of the support frame 20 to form an outwardly protruding arc, therefore, the long side of the L-shaped handle is far away from the One end of the short side can be arranged at the position where the first draw-in groove is positioned at the side wall of the support frame 20, so that the long side of the L-shaped carrying handle and the side wall of the support frame 20 are on the same horizontal line; meanwhile, the short side of the L-shaped carrying handle It is also located on the same level as the top wall of the support frame 20, providing a larger deformable range for the L-shaped carrying handle.

In this embodiment, the L-shaped handle has elastic deformation reset capability. When the operator holds the upper end of the L-shaped handle and moves it to the side close to the fan blade 101, the L-shaped handle will be deformed and slightly bent. , when the hand is released, the L-shaped handle will return to the original non-deformed state.

Therefore, when the operator presses the upper end of the L-shaped handle and moves to the side close to the fan blade 101, the engaging mechanism 202 moves synchronously and disengages from the clamping place, so that the fan box can be conveniently installed in a server such as Take off the fan; when it is necessary to install the fan, directly snap the engaging mechanism 202 into the engaging hole for installing the fan on the box where the fan is installed, such as in the server.

Further, as shown in Figure 1 and Figure 2 in the first embodiment of the present invention, hollow holes are also provided at the bends of the hand handle, which can facilitate the operator's hands to be inserted into the hollow holes to hold the hand handle, which is helpful for operation. Personnel use a more stable grip when handling the fan.

Further, as shown in Figure 1 in Embodiment 1 of the present invention, the engaging mechanism 202 is arranged on the handle near the lower end of the hollow hole. Specifically, the engaging mechanism 202 can be set as a triangular bump, which can more conveniently Make the operator hold the hand handle and press it. When pressing, the engaging mechanism 202 can be forcefully released from the engaging hole for installing the fan on the box such as the server where the fan is installed, and the disassembly and assembly are faster. .

Further, as shown in FIG. 1 and FIG. 2 in Embodiment 1 of the present invention, the diagonal position between the side wall and the bottom wall connected to the support frame 20 is correspondingly provided with a second card slot corresponding to the first card slot, The bottom of the second slot extends along the side wall of the support frame to the bottom wall of the support frame in an outwardly protruding arc.

Further, as shown in FIG. 2 in Embodiment 1 of the present invention, a terminal holder 203 is provided on the left side wall of the support frame 20 close to the bottom wall of the support frame 20, and a terminal holder 204 is provided on the terminal holder 203. The terminal The fixing seat 203 is used to fix the connecting terminal 204; the downward end of the connecting terminal 204 is used for plugging with the main board terminal, and the upward end is plugged with a terminal with a plurality of connecting wires, which plays the role of transmitting power and signals .

Further, as shown in FIG. 2 in Embodiment 1 of the present invention, a wire passage 103 connected to the fan frame 102 is also provided on the left side wall of the support frame 20 close to the terminal fixing seat 203. The wire passage 103 is used for Place the wires 104 connecting the fan frame 102 and the terminal 204, so that too many wires 104 will not be entangled in a disorderly way, or too scattered to affect the wiring; the wires 104 play the role of transmitting power and signals, and the wires 104 pass through the wires. The slot 103 is connected with the connection terminal 204, and when the fan is disassembled, the wires on the fan can also be disassembled conveniently.

Further, the support frame 20 is also provided with anti-vibration elastic arms 205, as shown in Figure 1 and Figure 2, a plurality of anti-vibration elastic arms 205 are overlapped with respect to the side wall and the top wall and the side wall and the bottom wall of the support frame The edges are parallel to each other; specifically, the anti-vibration elastic arm 205 can be set as an elastic protrusion, which can provide the fan with an elastic anti-vibration effect and avoid hard vibration of the fan.

Further, as shown in Fig. 1 and Fig. 2 in Embodiment 1 of the present invention, screw fixing holes 206 are provided at the opposite corners of the upper and lower ends of the support frame 20, which can be fixed or reinforced with screws when necessary.
