Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] See Figures 1-6 As shown, the present invention provides a self-weight vertical sealing door, including a wall 1, a door 3, and a control panel. The wall 1 has an inlet and outlet 2. Specifically, a door sealing ring 10 is provided along the edge of the opening of the inlet and outlet 2. The door sealing ring 10 is made of rubber material. The wall 1 is provided with a lifting drive assembly 4 for driving the door 3 to rise and fall. The wall 1 is also provided with a guide rail structure 7 for guiding the movement of the door 3. When the lifting drive assembly 4 drives the door 3 to fall to the lowest position, the door 3 achieves sealing of the inlet and outlet 2 under the guidance of the guide rail structure 7 and under its gravity.

[0031] This embodiment provides a specific guide rail structure 7, see the attached instruction manual. Figure 1 , 4As shown in Figure 5, the guide rail structure 7 has two symmetrically distributed around the door body 3. The guide rail structure 7 includes a wheel rail 701. A support rod 702 is fixedly installed on the side of the wheel rail 701 away from the door body 3. The support rod 702 is fixedly installed on the wall 1. Two sets of guide wheels 709 are provided on the left and right sides of the door body 3. Each set includes two guide wheels 709 distributed vertically. The wheel rail 701 is provided with a first inclined wheel rail 703 and a second inclined wheel rail 710 along the vertical direction. The first inclined wheel rail 703 and the second inclined wheel rail 710 are inclined in the same direction. The distance between the first inclined wheel rail 703 and the second inclined wheel rail 710 is the same as the distance between the two guide wheels 709 in the same vertical group. In practical application, as the door body 3 moves downward, due to its own weight and the guiding movement of the two sets of guide wheels 709 within the first inclined wheel rail 703 and the second inclined wheel rail 710 respectively, the door body 3 can achieve a sealed closure of the entrance and exit 2 when it descends to its lowest position.

[0032] Specifically, the first inclined wheel rail 703 has an opening slot 704 on the side near the wheel rail 701. A V-shaped guide rod 708 is provided at the opening slot 704. The tip of the V-shaped guide rod 708 is rotatably positioned in the opening slot 704 via a rotating shaft 705. The V-shaped guide rod 708 is made of iron. Two magnetic blocks 706 and 707 are respectively magnetically connected to the V-shaped guide rod 708. One end of the V-shaped guide rod 708 is magnetically connected to the first magnetic block 706 and the second magnetic block 707, thereby realizing the conversion of the rotation position of the V-shaped guide rod 708. When the end of the V-shaped guide rod 708 is magnetically connected to the first magnetic block 706, it serves to guide the upper guide wheel 709 into the first inclined wheel rail 703. When the end of the V-shaped guide rod 708 is magnetically connected to the second magnetic block 707, it serves to guide the lower guide wheel 709 further downward into the second inclined wheel rail 710.

[0033] See instruction manual attached Figure 1 and 6 As shown, the lifting drive assembly 4 includes two support blocks 401, which are fixedly mounted on the wall 1. A winding shaft 403 is rotatably mounted between the two support blocks 401. One end of the winding shaft 403 is driven to rotate by a motor 402 fixedly mounted on the wall 1. Several evenly distributed rope wheels 404 are fixedly mounted on the winding shaft 403 along its axial direction. One end of a hanging rope 405 is wound and fixedly connected to the outside of each rope wheel 404. The other end of the hanging rope 405 is hinged to the door body 3 through a hinge seat 406. The hanging ropes 405 are arranged parallel to each other. The output end of the control panel is electrically connected to the input end of the motor 402.

[0034] A locking structure 5 is provided on the guide rail structure 7. When the door 3 rises to its highest position, the locking structure 5 locks the door 3 in place. The locking structure 5 includes a first electric telescopic rod 5a, which is fixed to the wall 1 via a first fixed seat 5b. The outer side of the door 3 has an insertion hole 3a that engages with the push rod head of the first electric telescopic rod 5a. The output end of the control panel is electrically connected to the input end of the first electric telescopic rod 5a. Through the above-mentioned structural design, the locking structure 5 can lock the door 3 at its highest position, thus preventing it from falling.

[0035] It should be noted that, in order to cooperate with the aforementioned stopping structure 5 and the insertion hole 3a, a locking structure 6 is provided on the guide rail structure 7. When the door body 3 descends to its lowest position to seal the entrance and exit 2, the locking structure 6 locks and fixes the door body 3. The locking structure 6 includes a second electric telescopic rod 6a, which is fixedly mounted on the wall 1 via a second fixed seat 6b. The push rod head of the second electric telescopic rod 6a is connected to the insertion hole 3a on the outside of the door body 3. The output end of the control panel is electrically connected to the input end of the second electric telescopic rod 6a. Through the above specific structural design, when the door body 3 descends to its lowest position to close the entrance and exit 2, the locking structure 6 can cooperate with the insertion hole 3a to lock the door body 3, thus playing a firm and stable role.

[0036] The control panel includes a first control panel 8 and a second control panel 9, which are respectively located on the front and back sides of the wall 1. This allows for convenient control from both inside and outside the door 3.

[0037] Working principle:

[0038] In use, when the door 3 is closed, the output shaft of the motor 402 of the lifting drive assembly 4 rotates, thereby driving the winding shaft 403 to rotate. The rotation of the winding shaft 403 drives the rope winding wheel 404 on it to rotate. The rotation of the rope winding wheel 404 realizes the winding and unwinding of the hanging rope 405. When the hanging rope 405 is wound up, the door 3 moves upward. When the hanging rope 405 is unwound, the door 3 moves downward. During the downward movement of the door 3, the door 3 is guided along the wheel rail 701 by the guide wheel 709. The guide wheel 709 located at the bottom first passes through the first inclined wheel rail 703 and the V-shaped guide rod 7. 08 guides the lower guide wheel 709 to continue moving downwards and pushes the V-shaped guide rod 708 to rotate around the pivot 705. When the upper guide wheel 709 moves downwards, under the guidance of the V-shaped guide rod 708, the upper guide wheel 709 enters the second inclined wheel rail 710. With the cooperation of the guide wheel 709, the first inclined wheel rail 703 and the second inclined wheel rail 710, the door body 3 moves downwards towards the entrance and exit 2, so that during the descent of the door body 3, it approaches the entrance and exit 2 under its own weight and is tightly sealed with the door sealing ring 10 at the entrance and exit 2.

[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
