Preferably, the door is provided with a switch button, and the switch button is provided with an ascending button and a descending button.

Preferably, the air cylinder may be replaced by a hydraulic mechanism or other lifting mechanism, which is not limited herein.

Preferably, the first travel switch can prevent the door from descending when the door is not closed to a position over the step, and prevent the door from colliding with the step.

Preferably, the second travel switch can prevent the door from moving up and down in a state of being tightly closed and clinging to the sealing strip, so that the sealing strip is prevented from being damaged.

The utility model has the advantages that:

1. the door is reasonable in structural design, simple to operate and convenient to use, and the air cylinder is arranged at the position of the hinge, so that the door can move up and down, and step obstacles when the door is opened are avoided;

2. the plane bearings are arranged above and below the hinge shaft, so that the whole door can be in a floating state, when the door is integrally close to the sealing strip, the closer the door 2-compression sealing strip is to the box body, the airtight state can be formed in the box body, the plane bearings can also ensure that the hinges of the door are on the same axis in the opening and closing process, and ensure that the door and the door frame of the box body have accurate parallelism, and the plane bearings have strong practicability.

Description of the drawings:

for ease of illustration, the invention is described in detail by the following detailed description and accompanying drawings.

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a partial cross-sectional view of the present invention;

fig. 3 is a schematic view of the installation structure of the first travel switch and the second travel switch of the present invention.

1-a box body; 2-a door; 2-1-switch button; 3-a hinge sleeve; 4-hinge axis; 5-a planar bearing; 6-copper sheathing; 7-a cylinder; 8-adjusting the support; 9-a fixed seat; 10-a first travel switch; 11-a second travel switch; 12-sealing strip.

The specific implementation mode is as follows:

as shown in fig. 1 to fig. 3, the following technical solutions are adopted in the present embodiment: it contains box 1, door 2, hinge housing 3, hinge pin 4, flat bearing 5, copper sheathing 6, cylinder 7, adjust support 8, fixing base 9, first travel switch 10, second travel switch 11, sealing strip 12, be provided with door 2 on the box 1, hinge housing 3 is installed respectively at both ends about one side of door 2, install hinge pin 4 on the hinge housing 3, flat bearing 5 is all installed at the upper and lower both ends of hinge pin 4, install copper sheathing 6 on the hinge pin 4, install cylinder 7 on the hinge pin 4 of door 2 one side lower extreme, be provided with between one end of cylinder 7 and the hinge pin 4 and adjust support 8, the other end of cylinder 7 passes through fixing base 9 to be fixed on door 2, the below of box 1 is provided with first travel switch 10 and second travel switch 11, be provided with sealing strip 12 between box 1 and the door 2.

Wherein, the door 2 is provided with a switch button 2-1, and the switch button 2-1 is provided with an ascending button and a descending button; the air cylinder 7 can be replaced by a hydraulic mechanism or other lifting mechanisms, and is not limited herein; the first travel switch 10 can prevent the door 2 from descending when the door 2 is not closed to a position of crossing a step, and avoid the door 2 from colliding with the step; the second travel switch 11 can prevent the door 2 from moving up and down in a state of being tightly closed and clinging to the sealing strip 12, and the sealing strip 12 is prevented from being damaged.

The working principle of the specific embodiment is as follows: when the door is opened, the door 2 is opened to a certain opening degree and leaves the second travel switch 11, at this time, the door 2 is not tightly attached to the sealing strip 12, at this time, the ascending button on the switch button 2-1 is pressed, so that compressed air enters the cylinder 7 from the lower part of the piston of the cylinder 7, the hinge sleeve 3 of the door is pushed to ascend under the action of the cylinder shaft, the door 2 is driven to ascend synchronously, the bottom of the door 2 is higher than a step outside the door, and at this time, the door 2 can be completely opened manually; when the door is closed, the door 2 is closed to a certain opening degree, the first travel switch 10 is triggered, but the second travel switch 11 is not triggered, at this time, the door 2 is over the step and is not tightly attached to the sealing strip 12, and can descend, at this time, the descending button on the switch button 2-1 is pressed, so that compressed air enters the air cylinder 7 from the upper part of the piston of the air cylinder 7, the hinge sleeve 3 of the door is pushed to descend under the action of the air cylinder shaft, the door 2 is driven to descend synchronously, until the air cylinder shaft descends to the lowest end of the stroke, the door can be continuously closed until the second travel switch 11 is triggered, and the door 2 is completely closed and tightly attached to the sealing strip 12.

The door can move up and down by arranging the air cylinder at the hinge position, so that step obstacles when the door is opened are avoided; plane bearing all is equipped with from top to bottom of hinge pin, can be so that whole door be in a floating condition, and after the sealing strip was pressed close to the whole door, door compression sealing strip was close more to the box, can become an airtight state in the box, and plane bearing can also ensure that the hinge of door is opening and closing the in-process on same axis to ensure that door and box door frame have an accurate depth of parallelism, had stronger practicality.
