[0021] The magnetic lock body 3 is fixed on the cabin body 1, the magnetic lock suction plate 4 is fixed on the cabin door 2 by bolts, and the sealing strip 5 is installed and fixed on the cabin body 1 to form a closed sealing ring. According to electromagnetic theory, when the magnetic lock body 3 is energized by the outside world, a magnetic force is generated to adsorb the magnetic lock suction plate 4 fixed on the cabin door 2, and the cabin door 2 is closed, and the operation is simple and convenient; then the pressure in the cabin body 1 is increased, and the air pressure in the cabin body 1 increases, under the action of the air pressure difference between the inside and outside of the cabin body 1, the cabin door 2 is pressed onto the cabin body 1, thereby improving the closing effect of the cabin door 2 on the entrance and exit; when the pressure in the cabin reaches a predetermined pressure, the magnetic lock body 3 is powered off, the magnetic force on the magnetic lock body 3 disappears, and it is separated from the magnetic lock suction plate 4, and the cabin door 2 is closed to the entrance and exit under the action of air pressure. In this process, the magnetic lock body 3 is powered off to reduce the consumption of electricity, which is energy-saving and environmentally friendly.

When the cabin door 2 closes the entrance and exit of the cabin body 1, the cabin door 2 is pressed against the sealing strip 5; after the cabin door 2 closes the cabin body 1, the cabin door 2 is pressed against the sealing strip 5, thereby improving the sealing effect of the cabin body 1; when the magnetic lock body 3 is powered off, the magnetic force on the magnetic lock body 3 disappears, and it is separated from the magnetic lock suction plate 4 and the cabin body 1 is depressurized. When the pressure is lower than or equal to the pressure outside the cabin, the cabin door 2 is automatically opened by the elastic force of the sealing strip 5 installed on the cabin body 1, thereby facilitating the opening of the cabin door 2.

A clamping strip 53 is integrally formed on the inner side of the U-shaped strip 51, and a clamping groove for the clamping strip 53 to be clamped is provided on the mounting plate 16, and the clamping groove extends in a direction away from the cabin body 1; under the action of the U-shaped strip 51 and the clamping strip 53, the sealing strip 5 is easily installed on the cabin body 1; and under the action of the cylindrical strip 52, the compression effect of the sealing strip 5 is improved, thereby improving the sealing effect of the cabin body 1.

[0024] Reference Figure 4 , Figure 5 and Figure 6 When an emergency occurs in the cabin 1 and the power is accidentally cut off, although the magnetic lock body 3 and the magnetic lock suction plate 4 are powered off and separated, the cabin door 2 is difficult to open due to the pressure difference between the inside and outside of the cabin 1, which may easily cause panic among the users in the cabin 1. Therefore, in the embodiment of the present application, a separation plate 7 is provided on the outside of the cabin door 2, and the separation plate 7 is movably arranged on the outside of the cabin door 2. The initial position of the separation plate 7 is located on the outside of the sealing strip 5. A driving member 8 is provided on the cabin door 2, and the driving member 8 is used to drive the separation plate 7 to move and pass through the contact surface between the cabin door 2 and the sealing strip 5, so that the inside and outside of the cabin 1 are connected; when the cabin door 2 needs to be opened urgently, the separation plate 7 is driven to move by the driving member 8, and the separation plate 7 enters the sealing surface between the sealing strip 5 and the cabin door 2 and pushes open the sealing strip 5, so that the inside and outside of the cabin 1 are connected, and the cabin 1 is gradually depressurized. When the air pressure inside and outside the cabin 1 is consistent, the cabin door 2 is opened.

The sliding direction of the separation plate 7 is perpendicular to the opposite sealing strip 5. A separation block 9 is arranged at the end of the separation plate 7 facing the sealing strip 5. The cross-section of the separation block 9 is a right triangle. The driving member 8 includes a screw 81 threadedly connected to the outer side of the cabin door 2. The separation plate 7 is rotatably arranged on the screw 81. The rotation of the screw 81 drives the separation plate 7 and the separation block 9 to slide toward the sealing strip 5 and push open the sealing surface of the sealing strip 5 and the cabin door 2; rotate the screw 81, and the rotation of the screw 81 drives the separation plate 7 and the separation block 9 to slide, and the inclined surface of the separation block 9 enters the sealing surface, and pushes open the sealing strip 5 through the inclined surface of the separation block 9. The operation is simple and convenient.

[0026] Reference Figure 4 , Figure 5 and Figure 6 In order to facilitate the user to rotate the screw 81 in the cabin body 1, a driving rod 82 is provided on the inner side of the cabin door 2 and corresponds to the screw 81 and is parallel to the screw 81. A transmission rod 83 is provided between the driving rod 82 and the screw 81 and across the cabin door 2. The transmission rod 83 is rotatably arranged on the cabin door 2.

The rotation of the sleeve rod 811 drives the sliding rod 812 to rotate. The rotation of the sliding rod 812 drives the threaded portion 812 to rotate. The rotation of the threaded portion 812 drives the separation plate 7 to slide. When the separation plate 7 slides, it drives the sliding rod 812 to slide in the sleeve rod 811, thereby making it convenient for the driving rod 82 to drive the separation plate 7 to slide.

[0028] Reference Figure 4 , Figure 5 and Figure 6When the thickness of the separation block 9 and the separation plate 7 is large, it is easy to make it difficult for the material distribution block and the separation plate 7 to enter between the sealing strip 5 and the cabin door 2. Therefore, in the embodiment of the present application, a mounting groove 10 is provided on the surface of the separation plate 7 facing away from the cabin door 2, and a rotating plate 11 is rotatably arranged in the mounting groove 10.

When the separation block 9 enters between the sealing strip 5 and the cabin door 2, the rotating plate 11 is driven to rotate under the action of the separation member. The rotating plate 11 rotates in the direction away from the mounting groove 10, thereby driving the sealing strip 5 to separate from the cabin door 2, thereby facilitating the balance of the air pressure inside and outside the cabin body 1.

In this process, the magnetic lock body 3 is powered off to reduce the consumption of electricity, which is energy-saving and environmentally friendly.

When the air pressure inside and outside the cabin 1 is consistent, the hatch 2 is opened.
