[0024] A connecting plate 7 is arranged on the outer side of the isolation plate 6, and an arc-shaped slot 701 is opened on the connecting plate 7, and an axial hole 702 is arranged outside the arc-shaped slot 701. A movable shaft 10 is movably arranged in the configuration slot 601. A sealing plate 8 is arranged on the outer surface of the connecting plate 7, and a mounting hole 801 is arranged on the sealing plate 8. A shaft rod 901 is inserted into the middle upper part of the isolation plate 6 and the connecting plate 7, and a tightening V-shaped disk 9 is arranged at the end of the shaft rod 901. A connecting shaft 11 is inserted into both sides of the isolation plate 6 and the connecting plate 7, and a hexagonal nut 12 is arranged at the end of the connecting shaft 11. Two motors 2 are arranged symmetrically with each other. A tightening sleeve 13 is sleeved on the outer surface of the connecting shaft 11.

[0025] During the use of the utility model, the motor 2 is started: when the inflatable cabinet or the environmental protection cabinet needs to be operated, the motors 2 on both sides are started at the same time. The rotation of the motor 2 drives the rotating shaft 3 connected thereto to rotate.

[0026] Operation of the locking piece 4: As the rotating shaft 3 rotates, the locking piece 4 slides on the rotating shaft 3. When the U-shaped groove 401 on the locking piece 4 is aligned with a specific position on the rotating shaft 3, the locking piece 4 can be locked or unlocked by an external operating tool through the U-shaped groove 401.

[0027] Spring 5 and limit rod 501: The spring 5 on the lower side of the main frame 1 plays a role of buffering and resetting. When the locking piece 4 is subjected to external force, it can compress the spring 5 and move. When the external force disappears, the spring 5 returns the locking piece 4 to its original position through the limit rod 501.

[0028] The connecting plate 7 is used to connect the isolation plate 6 and the main frame 1. The shaft 901 and the connecting shaft 11 therebetween provide structural support and rotation functions.

[0029] The shaft rod 901 and the tightening V-shaped plate 9: The shaft rod 901 penetrates into the middle upper part of the isolation plate 6 and the connecting plate 7, and the tightening V-shaped plate 9 is used to fix the shaft rod 901 to ensure the stability of the structure.

[0030] Connecting shaft 11 and hexagonal nut 12: The connecting shaft 11 penetrates both sides of the isolation plate 6 and the connecting plate 7 and is fixed by the hexagonal nut 12, providing additional structural stability.

[0031] Dual motors 2: The motors 2 on both sides are symmetrically arranged to provide better balance and stability, and reduce the unbalanced load problem that may occur when a single motor is working.

[0032] Locking piece 4 and U-shaped groove 401: The locking piece 4 makes the operation more convenient. The U-shaped groove 401 can be used to easily lock or unlock, thereby improving the operation efficiency and safety.

[0033] Spring 5 buffering: The setting of spring 5 can effectively absorb external impact, protect the mechanism from damage, and provide an automatic reset function.

[0034] Modularity: The entire mechanism is modularized, which facilitates repair and replacement of parts and reduces maintenance costs.

[0035] Strong versatility: This dual-motor 2-operating mechanism can be used for both inflatable cabinets and environmental protection cabinets. It has strong versatility and reduces production and operating costs.

[0036] Simple structure: The overall structure is reasonable and the parts fit closely together, making the whole mechanism both sturdy and easy to operate.

[0037] Function of the fastening sleeve 13: The fastening sleeve 13 is sleeved on the outer surface of the connecting shaft 11 to further fix the connecting shaft 11 to prevent it from loosening or falling off. During long-term use, the fastening sleeve 13 can effectively maintain the stability of the connecting shaft 11 and improve the service life and safety of the entire operating mechanism.

[0038] Functions of the fastening sleeve 13:

[0039] Preventing loosening: When the connecting shaft 11 is subjected to external force or vibration caused by long-term operation, the fastening sleeve 13 can provide an additional fixing force to prevent the connecting shaft 11 from loosening or slipping out of the shaft hole 702.

[0040] Increase friction: The fastening sleeve 13 is usually made of rubber or other high-friction materials, which can increase the friction between the connecting shaft 11 and the shaft hole 702, thereby helping to maintain the stability of the connecting shaft 11.

[0041] The fastening sleeve 13 has a certain elasticity, can absorb and buffer the vibration and impact generated during the working process, and protect the connecting shaft 11 and related components from damage. The fastening sleeve 13 is usually a structure that is easy to install and disassemble, which is convenient for maintenance and replacement of components.

[0042] Working principle: Installation: After the connecting shaft 11 passes through the shaft hole 702, the fastening sleeve 13 is put on the outer surface of the connecting shaft 11. Usually, the inner diameter of the fastening sleeve 13 will be slightly larger than the outer diameter of the connecting shaft 11, so that it can be easily inserted. Fixing: When the fastening sleeve 13 is put on the connecting shaft 11, it will form an additional fixing layer between the connecting shaft 11 and the shaft hole 702, and fix the connecting shaft 11 in the shaft hole 702 through its friction and elasticity. Working: During the operation of the inflatable cabinet or the environmental protection cabinet, the connecting shaft 11 may be affected by various external forces and vibrations, but due to the presence of the fastening sleeve 13, it can effectively prevent the connecting shaft 11 from loosening or falling off. Maintenance: When the connecting shaft 11 needs to be replaced or maintained, the fastening sleeve 13 can be easily removed from the connecting shaft 11. After completing the necessary maintenance work, the fastening sleeve 13 can be reinstalled.
