A group of control keys 8 located at the top of the control panel 7 is used to control the forward and reverse operation of the motor 603, and a group of control keys 8 located at the bottom of the control panel 7 is used to control the switches of the two electromagnets 104. When the external power supply is turned on, the user presses a control key 8 marked in reverse in one group of control keys 8 to control the motor 603 to work in the reverse direction. When the motor 603 works in the reverse direction, it drives the worm 602 to rotate in the reverse direction. When the worm 602 rotates in the reverse direction, it drives the worm wheel 601 to rotate in the reverse direction. The worm wheel 601 rotates in the reverse direction. When the second gear 10 rotates, it drives the second round rod 6 and the second gear 10 to rotate in the opposite direction. When the second gear 10 rotates in the opposite direction, it drives the first gear 9 and the first round rod 4 to rotate. When the first round rod 4 rotates on the fixed block 3, it drives the outer door 5 to rotate. When the outer door 5 rotates, it separates from the door opening 101, which is convenient for users to enter, helps to simplify the operation process of users, and is convenient for users to use.

An inner frame 102 is provided at one end, a sealing ring 103 is provided at the end of the inner frame 102 close to the outer door 5, two electromagnets 104 are provided at the end of the door opening 101 close to the outer door 5, an inner door 501 is slidably provided at the end of the outer door 5 close to the electromagnet 104, a plurality of elastic members 502 are provided at the end of the inner door 5 located inside the outer door 5, and the ends of the plurality of elastic members 502 away from the inner door 501 are provided on the inner wall of the outer door 5, the two electromagnets 104 are used in conjunction with the inner door 501, the adsorption force generated by the two electromagnets 104 is greater than the elastic force of the elastic members 502, and another group of control keys 8 is electrically connected to the two electromagnets 104.

[0041] In this embodiment, when the door opening 101 needs to be closed during use, the user presses the control key 8 marked with the positive mark in one group of control keys 8 to control the motor 603 to work in the forward direction, so as to rotate the outer door 5 and close the door opening 101. Then, the user presses the control key 8 marked with the open mark in another group of control keys 8 to control the two electromagnets 104 to work. When the two electromagnets 104 work, they generate magnetic force to attach the inner door 501, thereby driving the inner door 501 to move toward the inner frame 102. When the inner door 501 fits the electromagnet 104, the sealing ring 103 fixed on the inner frame 102 is squeezed, thereby reducing the sealing ring 103 and the inner door 501. The gap of the door 501 enhances the sealing of the cabin 1. When the inner door 501 moves, the elastic member 502 fixed on the inner wall of the outer door 5 is stretched. When the door opening 101 needs to be opened, the user presses the relevant control key 8 in another group of control keys 8 to control the two electromagnets 104 to stop working. The elastic member 502 loses the external force and pulls the inner door 501 back into the outer door 5. Then, the control key 8 with the reverse mark in one group of control keys 8 is pressed to control the motor 603 to work in the reverse direction, and the outer door 5 is separated from the door opening 101, which is convenient for users to enter and exit, and is conducive to avoiding the staff from manually turning the outer door 5, so as to reduce the labor intensity of users.

[0042] Working principle: When in use, the outer surfaces of the multiple control keys 8 on the control panel 7 are marked with switches. A group of control keys 8 located at the top of the control panel 7 are used to control the forward and reverse operation of the motor 603. A group of control keys 8 located at the bottom of the control panel 7 are used to control the switches of the two electromagnets 104. After the external power supply is turned on, the user presses a control key 8 marked in reverse in one group of control keys 8 to control the motor 603 to work in the reverse direction. When the motor 603 works in the reverse direction, it drives the worm 602 to rotate in the reverse direction. When the worm 602 rotates in the reverse direction, it drives the worm wheel 601 to rotate in the reverse direction. When the worm wheel 601 rotates in the reverse direction, it drives the second round rod 6 and the second gear 10 to rotate in the reverse direction. When the second gear 10 rotates in the opposite direction, it drives the first gear 9 and the first round rod 4 to rotate. When the first round rod 4 rotates on the fixed block 3, it drives the outer door 5 to rotate. When the outer door 5 rotates, it separates from the door opening 101, which is convenient for users to enter, which is conducive to simplifying the operation process of users and convenient for users to use. The protective shell 2 and the cabin body 1 are installed and fixed by bolts, which is convenient for disassembly and assembly of the protective shell 2. At the same time, the protective shell 2 is used to protect the motor 603, the worm 602 and the worm wheel 601 and other structures. When in use, when it is necessary to close the door opening 101, the user presses the control key 8 marked with the positive mark in one group of control keys 8 to control the motor The machine 603 works forward, which is convenient for rotating the outer door 5 and closing the door opening 101. Then the user presses the control key 8 marked with "open" in another group of control keys 8 to control the two electromagnets 104 to work. When the two electromagnets 104 work, they generate magnetic force to attach the inner door 501, thereby driving the inner door 501 to move toward the inner frame 102. When the inner door 501 fits the electromagnet 104, the sealing ring 103 fixed on the inner frame 102 is squeezed, thereby reducing the gap between the sealing ring 103 and the inner door 501, and enhancing the sealing of the cabin 1. The adsorption force generated by the electromagnet 104 on the inner door 501 is greater than the elastic force of the elastic member 502. When the inner door 501 moves The elastic member 502 fixed on the inner wall of the outer door 5 is stretched. When the door opening 101 needs to be opened, the user presses the control key 8 marked in the other group of control keys 8 to control the two electromagnets 104 to stop working. The elastic member 502 loses the external force and pulls the inner door 501 back into the outer door 5. Then, the control key 8 marked in the opposite direction in one group of control keys 8 is pressed to control the motor 603 to work in the reverse direction, and separate the outer door 5 from the door opening 101, which is convenient for users to enter and exit, and is beneficial to avoid the staff from manually turning the outer door 5, so as to reduce the labor intensity of users. The model of motor 603 is 130ZFMA1-01D5CQNM-SY.
