Detailed Implementation
[0020] 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.
[0021] like Figure 1-3 As shown, this utility model provides a fan door opening and closing transmission device, which includes a drive mechanism 1, a transmission mechanism 2, and a mounting mechanism 3 for connecting the door body. The drive mechanism 1 is connected to the transmission mechanism 2, and the transmission mechanism 2 is connected to the mounting mechanism 3. The drive mechanism 1 includes an electric push rod 106, a first fixed seat 102, and a mounting frame 104. The first fixed seat 102 is connected to the mounting frame 104, and the mounting frame 104 is provided with a fixed connecting rod 103, which passes through the first fixed seat 102. The transmission mechanism 2 includes a second fixed seat 201 and a connecting frame 202. The second fixed seat 201 is connected to the connecting frame 202 and the electric push rod 106. The mounting mechanism 3 includes a connecting rod 303 and a rotating frame 302 provided on the connecting rod 303. The rotating frame 302 is connected to the connecting frame 202 and the connecting rod 303.
[0022] This embodiment is applicable to new energy storage cabinets, charging cabinets, computer rooms, and sealed workshop exhaust systems. The push rod is connected to a micro motor, which transmits power. When opening or closing is needed, the micro motor is activated, which is faster than manual switching. Using an electrically controlled motor for opening and closing ensures better sealing performance when the fan stops operating, effectively preventing dust and rainwater intrusion. Its maximum opening angle is 70±10 degrees, compared to the traditional 60±10 degrees. This increased opening angle improves ventilation and heat dissipation. The external hexagonal bar design makes the opening and closing more secure, preventing loosening or slippage.
[0023] Furthermore, the first fixing seat 102 is fixedly connected to the mounting bracket 104 via a fixed connection, and the fixing rod 303 is provided with a plurality of external hexagonal nuts 101, and the fixing rod 103 and the mounting bracket 104 are integrally formed.
[0024] The fixed connection between the first fixed base 102 and the mounting bracket 104 ensures the stability of the overall structure, effectively withstanding external forces and vibrations, and reducing the possibility of loosening or displacement during use. The fixed connecting rod 103 is integrally formed with the mounting bracket 104, eliminating weaknesses at the connection point, enhancing the overall structural strength and durability, and reducing the risk of failure due to wear or loosening at the connection point. The design of multiple external hexagonal nuts 101 simplifies the installation and disassembly process, allowing users to operate with common tools (such as wrenches), saving time and effort. The mounting bracket 104 and the fixed base can be quickly assembled and disassembled, facilitating maintenance and replacement, and improving the flexibility of use.
[0025] Furthermore, the mounting bracket 104 is U-shaped, and through holes are provided on both sides of the mounting bracket 104. The mounting bracket 104 is connected to the electric push rod 106. One end of the electric push rod 106 near the mounting bracket 104 is provided with a second through hole. A first fixing pin 105 is also provided at the connection between the mounting bracket 104 and the electric push rod 106.
[0026] The U-shaped mounting bracket 104 provides excellent structural support, effectively distributing the load and enhancing overall stability, making it suitable for bearing significant forces and pressures. A first fixing pin 105 is provided at the connection between the mounting bracket 104 and the electric push rod 106, effectively preventing loosening and ensuring a secure and safe connection during use.
[0027] Furthermore, the connecting frame 202 is disposed on the second fixed base 201, and the connecting frame 202 is connected to the electric push rod 106. A second fixing pin 107 is provided at the connection between the connecting frame 202 and the electric push rod 106. Both the second fixed base 201 and the connecting frame 202 are provided with mounting slots. The second fixing pin 107 passes through the mounting slots of the second fixed base 201 and the connecting frame 202 in sequence and then connects to the electric push rod 106.
[0028] A third fixing pin 203 is provided at the connection between the connecting frame 202 and the rotating frame 302. Both the connecting frame 202 and the rotating frame 302 are provided with through holes three, and the third fixing pin 203 passes through the through holes three.
[0029] The design of the second fixing pin 107 simplifies the connection between the connecting bracket 202 and the electric push rod 106. Users only need to pass the pin through the mounting slot to complete the installation, saving time and labor costs. Similarly, by pulling out the second fixing pin 107, users can quickly disassemble the connecting bracket 202, facilitating maintenance and replacement and improving operational flexibility.
[0030] Furthermore, the connecting rod 303 is also equipped with multiple bearings 301, which are coaxially arranged with the connecting rod 303. The rotation angle of the connecting rod 303 via the rotating frame 302 is greater than 70°, and the connecting rod 303 is hexagonal. Its maximum opening and closing angle is 70±10 degrees, while the traditional opening and closing angle is 60±10 degrees. Increasing its opening and closing angle is more conducive to ventilation and heat dissipation. The hexagonal rod design makes the opening and closing more secure and less prone to loosening or slippage.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
