When the closed door 16 is closed, when the movable door frame 10 is positioned at the highest position, the movable door frame 10 is farthest away from the fixed door frame 21, the pressure spring 11, the arc-shaped block 55 and the retaining spring 56 are in a compressed state, the limit spring 14, the fixed spring 26, the pushing spring 27, the disconnecting spring 49, the free spring 60, the reciprocating spring 43, the balance spring 37, the fixed position spring 57, the manual return spring 58 and the pulling spring 29 are in a relaxed state, the push block 18 is positioned at the lowest position, the transformation sliding block 59 is positioned at the uppermost position, the stabilizing block 39 is positioned at the highest position, and the driving connecting rod 64, the moving connecting rod 63 and the long connecting rod 40 are superposed on one plane, the closing plate 54 has extrusion force on the ground, so that two closed environments are formed on two sides of the closing plate 54, the driven gear 50 and the power gear 51 are not meshed at the moment, the downward push rod 48 is positioned at the highest position, and the starting wheel 45 is not contacted with the ground.

When the door is normally installed, firstly, the fixed position required by the door frame 21 is found, the motor 23 in the airtight door 16 is started to drive the driving connecting rod 64 to rotate, the moving connecting rod 63 is driven to move, the rotating loop bar 62 is driven to rotate, the long connecting rod 40 is driven to keep moving vertical to the ground, the moving loop bar 38 is driven to translate along the chute of the chute fixing plate 22, the stabilizing block 39 is driven to move, the rotating frequency of the motors 23 at the diagonal angles is the same, the rotating frequency of the adjacent motors 23 is opposite, so that the whole airtight door 16 is driven to move, specifically, when the driving connecting rod 64 rotates to the position shown in figure 11, the stabilizing block 39 is in contact with the ground, when the driving connecting rod 64 rotates clockwise, the airtight door 16 is driven to move upwards, when the driving connecting rod 64 rotates to the position of the driving connecting rod 64 which is in a mirror image of the vertical rod 24, the stabilizing block 39 just begins to be separated from the ground, and the circularly reciprocating driving connecting rod 64 always rotates, driving the closed door 16 to move to the position where the fixed door frame 21 is installed, wherein the angle between the closed door 16 and the fixed door frame 21 is formed, a pair of driving connecting rods 64 at opposite corners is located at the lowest position, the door plate is lifted to the highest position, then the motor 23 rotates slowly, the hinge shaft on the closed door 16 is inserted into the hinge hole on the fixed door frame 21 in an arc form, after the completion, the motor 23 returns to the original state, a hole for moving the door frame 10 is chiseled on the wall opposite to the fixed door frame 21, the pressure spring 11 and the sealing rubber 12 are installed on four surfaces in the wall hole, the moving door frame 10 is directly placed in the chiseled hole in the wall, then the manual extrusion 80 is carried out, and the transformation sliding block 59 is placed in a groove in the closed door 16;

after the door frame is installed, if the door frame is in a sealed state, a door frame starting switch is pressed, at the moment, a suction relay 52 is started to suck a closing plate 54, the closing plate 54 leaves the ground, a downward push rod 48 is pressed to drive an opening rod 20 to rotate, when an automatic locking block 47 passes through a baffle hole which is protruded on a movable door frame 10 and is compressed through an inclined plane, the automatic locking block is locked in the hole under the thrust of a free spring 60, a starting wheel 45 is in contact with the ground, the starting wheel 45 moves to drive a driven shaft 46 to move, a driven gear 50 moves and can be meshed with a power gear 51, the power gear 51 provides power to drive the starting wheel 45 to rotate, so that the movable door frame 10 is driven to move to the lowest position, the power gear 51 stops rotating, the opening relay 42 is pushed to start to push a small push block 44 to move, so that the automatic locking block 47 is pushed away from the hole, and then the opening rod 20 is reset under the tension of a disconnecting spring 49, the opening relay 42 and the suction relay 52 are pushed away and the starting is stopped at the same time, so that under the action of the positioning spring 53 and the retaining spring 56, the closing plate 54 stops moving the doorframe 10 by the friction force with the ground after being reset, the closing button of the door is pressed, the rotating motor 32 is started, the limit push rod 33 rotates around the rotating motor 32, so that the driving motor 34 rotates around the rotating motor 32, the transformation slide block 59 slides in the groove of the closed door 16 and drives the closed door 16 to rotate, at the moment, the inclined plane of the one-way limit block 13 is extruded and retracted by the moving doorframe 10, the door is popped up and clamped in the moving doorframe 10 under the action of the limit spring 14 after passing through the hole in the moving doorframe 10, meanwhile, the push block 18 is driven to press the doorframe by the push rod 19 manually, the push block 18 is driven to press the doorframe, the push block 25 is compressed by the push block 18, so that the spring 27 drives the anti-off block 41 to move, so that the spring 27 pushes the sealing plate 28 to move backwards, the trigger rod 30 firstly touches the ground, so that the belt piston 31 moves downwards, the pulling spring 29 is stretched, the piston 31 pushes the sealing plate 28 to move upwards, and the sealing plate 28 extrudes the back closed space upwards and backwards;

if the closed door needs to be opened, the push rod 19 is manually rotated, the sealing plate 28 is reset, the limiting relay 15 is started to suck the one-way limiting block 13, the rotating motor 32 rotates reversely, the closed door 16 is opened, the limiting relay 15 stops working, if goods with large feeding amount are needed, after the closed door 16 is opened, the switch of the movable door frame 10 is started, the suction relay 52 is started, the downward push rod 48 pushes backwards, the power gear 51 rotates reversely, the movement of the movable door frame 10 is completed, in addition, the wall body is aged and collapsed or the hinge part cracks, or when violent vibration is encountered, the balancing block 35 slides to touch the contact 36, the motor 23 is started, and at the moment, all the stabilizing blocks 39 grab and fix the closed door 16.

The invention has the beneficial effects that: according to the invention, the carrying cavity is arranged, so that the sealed door can be automatically installed on the fixed door frame, and then the sealed door can be stably held by the carrying cavity after receiving an inclination force, so that the sealed door is prevented from being damaged by toppling over, and the sealed door can be automatically installed through the carrying cavity of the sealed door under the condition that the sealed door is inconvenient to carry by using a forklift, so that manpower is saved, the condition that the sealed door is too heavy to cause damage to manual carrying is ensured, and the safety is improved;

the invention is also provided with the starting wheel, thereby facilitating the movement and the stop of the movable door frame according to the requirements, increasing the volume of the goods entering the door and facilitating the transportation of the goods by people.
