DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In this application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0039] The embodiment of the present invention provides a sealed sliding door. Figures 1 to 5 , Figure 1 Schematic diagram of the structure of a sealed sliding door, which includes: a door body 1, a first torsion spring assembly, a second torsion spring assembly, a first guide assembly 4 and a second guide assembly;

[0040] The first guide assembly 4 and the second guide assembly are arranged on the same side of the door opening, and the first guide assembly 4 is located below the second guide assembly;

[0041] The lower end of the door body 1 is slidably arranged on the first guide assembly 4 through the first torsion spring assembly;

[0042] The upper end of the door body 1 is slidably arranged on the second guide assembly through the second torsion spring assembly;

[0043] The first torsion spring assembly and the second torsion spring assembly are used to provide elastic restoring force to the door body 1 so that when the door body 1 slides to a preset position, the door body 1 is pushed to seal against the four sides of the door opening.

[0044] It should be noted that the first torsion spring assembly and the second torsion spring assembly can provide elastic restoring force for the door body 1 in real time. The elastic restoring force can make the door body 1 close to the door opening, and then after the door body 1 is closed, the door body 1 can continue to be sealed in contact with the four sides of the door opening to avoid the pressure in the cabin 8 from decreasing.

[0045] In the embodiment of the present invention, the first guide assembly 4 and the second guide assembly are arranged on the same side of the door opening, so that the first guide assembly 4 is located below the second guide assembly, the lower end of the door body 1 is slidably arranged on the first guide assembly 4 through the first torsion spring assembly, and the upper end of the door body 1 is slidably arranged on the second guide assembly through the second torsion spring assembly. The first torsion spring assembly and the second torsion spring assembly provide elastic restoring force to the door body 1, so that when the door body 1 slides to a preset position, it pushes the door body 1 to seal with the four sides of the door opening. Through the sealed sliding door disclosed above, the first guide assembly 4 and the second guide assembly can be arranged on one side of the door opening, and the door body 1 can be slidably arranged on the first torsion spring assembly and the second torsion spring assembly The torsion spring assembly slide is arranged on the first guide assembly 4 and the second guide assembly, so that the door body 1 can be pushed and pulled along the first guide assembly 4 and the second guide assembly. Since the first torsion spring assembly and the second torsion spring assembly can provide elastic restoring force for the door body 1, when the door body 1 moves to the preset position, the first torsion spring assembly and the second torsion spring assembly can push the door body 1 to seal in contact with the four sides of the door opening, and then achieve sealing after the door body 1 is closed. Compared with the existing casement method, the present application can effectively reduce the range of movement of the door body 1, so that more equipment can be placed in the cabin 8, thereby improving the utilization rate of the space in the cabin 8 and avoiding wasting space in the cabin 8.

[0046] Specifically, the first guide assembly 4 is identical to the second guide assembly, and the first torsion spring assembly is identical to the second torsion spring assembly;

[0047] A first bearing column 25 and a second bearing column 26 are vertically provided on the lower end surface of the door body 1;

[0048] The first torsion spring assembly includes: a first torsion spring arm 21, a second torsion spring arm 22, a first torsion spring 23 and a second torsion spring 24;

[0049] The first guide assembly 4 includes: a guide member 41, a guide rail and a slider 43;

[0050] The guide rail is set on one side of the door opening;

[0051] The guide member 41 is provided between the guide rail and the door opening;

[0052] The slider 43 is slidably arranged on the guide rail;

[0053] One end of the first torsion spring arm 21 is rotatably connected to the first bearing column 25 , and the other end is rotatably connected to the slider 43 ;

[0054] One end of the second torsion spring arm 22 is rotatably connected to the second bearing column 26 , and the other end is rotatably connected to the slider 43 ;

[0055] The guide member 41 is provided with a first slot 411 and a second slot 412 on one side close to the guide rail;

[0056] One end of the first torsion spring 23 is fixed to the slider 43 , and the other end is fixed to the first torsion spring arm 21 ;

[0057] One end of the second torsion spring 24 is fixed to the slider 43 , and the other end is fixed to the second torsion spring arm 22 ;

[0058] The door body 1 moves to a preset position, and the first torsion spring 23 and the second torsion spring 24 provide elastic restoring force to the door body 1 , so that the first bearing column 25 is snapped into the first slot 411 , and the second bearing column 26 is snapped into the second slot 412 .

[0059] It should be noted that, by providing the guide member 41, when the slider 43 slides along the guide rail, the door body 1 moves close to the guide member 41, thereby realizing the pushing and pulling of the door body 1, and one end of the first torsion spring arm 21 is rotatably connected to the first bearing column 25, and the other end is rotatably connected to the slider 43, one end of the second torsion spring arm 22 is rotatably connected to the second bearing column 26, and the other end is rotatably connected to the slider 43, and one end of the first torsion spring 23 is fixed to the slider 43, and the other end is fixed to the first torsion spring arm 21, One end of the second torsion spring 24 is fixed to the slider 43, and the other end is fixed to the second torsion spring arm 22, so that the first torsion spring 23 and the second torsion spring 24 can provide elastic restoring force for the door body 1 in real time, and open a first slot 411 and a second slot 412 on the side of the guide member 41 close to the guide rail. When the door body 1 moves to the preset position, the first torsion spring 23 and the second torsion spring 24 cause the first bearing column 25 to be clamped into the first slot 411, and the second bearing column 26 to be clamped into the second slot 412, so that the door body 1 is close to the door opening.

[0060] It should also be noted that the distance between the first bearing column 25 and the second bearing column 26 can be selected by those skilled in the art according to the width of the door body 1 .

[0061] Preferably, Figure 4 The torsion spring can be fixed by providing a limiting column on the slider 43 and a fixing column fixed to one end of the torsion spring on the first torsion spring arm 21.

[0062] Preferably, Figure 4 One end of the first torsion spring arm 21 is rotatably connected to the first bearing column 25 , and the other end of the first torsion spring arm 21 can be rotatably connected to the slider 43 through the bearing 29 .

[0063] Specifically, the guide member 41 is a nylon guide rail.

[0064] It should be noted that setting the guide member 41 as a nylon guide rail can effectively reduce the friction between the first bearing column 25 and the second bearing column 26 and the guide member 41, making it easier to push and pull the door body 1 and effectively reducing noise.

[0065] Specifically, the first card slot 411 is parallel to the second card slot 412 , and the angle between the first card slot 411 and the closing direction of the door body 1 is less than 90 degrees.

[0066] It should be noted that the first slot 411 and the second slot 412 are arranged in parallel, and the angle between the first slot 411 and the closing direction of the door body 1 is less than 90 degrees. Therefore, when the door body 1 moves to the preset position, the first bearing column 25 is more easily inserted into the first slot 411, and the second bearing column 26 is more easily inserted into the second slot 412. When the door body 1 needs to be opened, the first bearing column 25 can be easily disengaged from the first slot 411 and the second bearing column 26 can be disengaged from the second slot 412 under the action of thrust.

[0067] Furthermore, the first guide assembly 4 and the second guide assembly are both arranged in the door opening.

[0068] It should be noted that since the pressure inside the micro-hyperbaric chamber 8 is greater than the external pressure, the first guide assembly 4 and the second guide assembly are arranged in the door opening. Under the action of the internal and external pressure difference, the door body 1 can be further made to stick to the four sides of the door opening, thereby improving the sealing effect.

[0069] Furthermore, the sealed sliding door further includes: foam strips arranged around the door body 1.

[0070] It should be noted that by providing foam strips around the door body 1, the sealing effect between the door body 1 and the four sides of the door opening can be improved.

[0071] It should also be noted that foam strips or sealing rubber can be provided around the door body 1, and those skilled in the art can replace them according to needs.

[0072] Furthermore, the sealed sliding door further comprises: a sealing strip 6 arranged around the door opening.

[0073] It should be noted that by providing sealing strips 6 around the door opening, the sealing effect between the door body 1 and the door opening can be further improved.

[0074] Furthermore, the door body 1 is provided with a handle 7 .

[0075] It should be noted that, by providing a handle 7 on the door body 1 , it is convenient for staff to open and close the door body 1 .

[0076] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
