[0011] In a possible design, the counterweight mechanism includes a winding wheel, a steel wire and a counterweight, the winding wheel is fixedly sleeved on the output shaft, one end of the shielding cloth winding support is fixedly connected with one side of the winding wheel, one end of the steel wire is fixedly connected with one side of the winding wheel, the first mounting bracket is provided with a moving hole for facilitating the movement of the steel wire, and the bottom end of the steel wire is fixedly connected with the top of the counterweight.

[0012] In a possible design, the crankshaft, the secondary driven shaft and the output shaft are all made of high-strength carbon steel stainless steel material.

[0013] In a possible design, the material of the manual crank is high-strength carbon steel material.

[0014] In one possible design, one end of the electromagnetic shielding cloth is fixedly connected with one side of the shielding cloth winding support.

[0015] In this application, when in use, hold the manual crank and rotate it clockwise or counterclockwise. The manual crank is fixedly connected with the crank driving shaft, so rotating the crank will drive the crank driving shaft to rotate. With the rotation of the crank driving shaft, the driving small gear will be driven to rotate by the driving small gear. Since the driving small gear and the driving large gear are both keyed connected on the secondary driven shaft, the driving large gear will also rotate. The driving large gear is engaged with the output gear, thereby driving the output shaft to rotate (realizing a process of converting low-speed high-torque to high-speed low-torque; assuming that the primary-to-secondary speed ratio is 1:10, the handle will drive the driven wheel to rotate 10 times for one revolution. The large gear on the driven wheel also rotates 10 times. The large gear on the driven shaft rotates 10 times, which will drive the output shaft to rotate 100 times, thereby realizing an acceleration process. The final effect is that the handle rotates 1 revolution, and the output shaft will rotate 100 revolutions, which can realize efficient torque transmission and speed conversion, making the lifting movement of the electromagnetic shielding cloth fast, smooth and smooth).

When the electromagnetic shielding cloth is wound or released, the counterweight will exert a gravity on the winding wheel through the steel wire, which is opposite to the direction of the movement of the electromagnetic shielding cloth, thereby maintaining the overall balance and stability.

[0017] By manually rotating the manual crank, the rotary motion is converted into the linear lifting motion of the shielding door (electromagnetic shielding cloth), thereby realizing the opening and closing operation of the door. Compared with the traditional electric drive or complex mechanical transmission method, this design has significant advantages.

[0018] In terms of operation convenience, the crank design does not need to rely on external power supply and can be manually operated at any time in any environment. It is especially suitable for some equipment usage scenarios in unstable power supply or emergency situations, such as power failure or equipment failure requiring emergency opening of the shielding door for equipment maintenance or cargo handling. The operator only needs to rotate the crank to easily control the state of the shielding door, greatly improving the emergency response capability and use flexibility of the equipment.

[0020] The electromagnetic shielding cloth is used as the radio frequency signal isolation material, the crank handle operation of short distance is used to realize the large stroke opening and closing of the roller shutter door, the gravity of the inner counterweight and the gradually falling of the roller cloth in the opposite direction is neutralized, the manual operation lever is more labor-saving and convenient, the goods entrance and exit of the electromagnetic shielding door and the RFID scanning equipment are completely matched to avoid the radio frequency signal leakage, the function effect is realized, the equipment cost is reduced, and the related enterprises are facilitated to use.

[0021] The beneficial effects in the utility model are as follows:

[0022] In the utility model, the crank handle type RFID scanning equipment shielding door passes through the transmission mechanism, holds the manual crank handle, rotates in the clockwise direction or the counterclockwise direction, the manual crank handle is fixedly connected with the crank handle driving shaft, therefore, rotating the crank handle can drive the crank handle driving shaft to rotate, along with the rotation of the crank handle driving shaft, the crank handle driving gear can drive the driven pinion to rotate, since the driven pinion and the driven gear are all key-connected on the secondary driven shaft, therefore, the driven gear also rotates, the driven gear is engaged with the output gear, thereby driving the output shaft to rotate, the output shaft drives the winding wheel and the shielding cloth winding support to rotate, along with the rotation of the output shaft, the shielding cloth winding support starts to wind or release the electromagnetic shielding cloth.
