Description

Technical Field

[0001] The utility model relates to a sliding sealing device for an oxygen chamber translation door of an oxygen chamber, belonging to the technical field of oxygen chamber door structures. Background Art

[0002] The door of the hyperbaric oxygen chamber mainly serves to seal and isolate the cabin from the outside world. When the door is closed, the door panel slides along the door frame to a predetermined position through the cooperation of the lifting mechanism and the sliding device. In order to enhance the sealing effect of the cabin and prevent the leakage of pressurized gas, the current method of instantaneous pressurization after closing the door is generally adopted. The large flow of gas generated instantly acts on the door panel, so that the door panel is pressed tightly against the door frame by strong pressure sealing.

[0003] The above sliding door mainly has the following technical defects:

[0004] 1. The noise and pressure difference generated by instantaneous pressurization cause serious discomfort to the ears and bodies of people in the cabin, and the experience is very bad.

[0005] 2. When there is a deviation in the contact position between the door panel and the door frame, instantaneous pressure will cause local hard contact, resulting in extrusion damage at local points.

[0006] 3. The rubber strip is worn and has a short service life. Summary of the invention

[0007] The utility model aims to solve the above-mentioned various problems and further provides a sliding sealing device for an oxygen chamber sliding door.

[0008] In order to solve the above problems, the technical solution adopted by the utility model is:

[0009] The sliding sealing device of the oxygen cabin sliding door is adapted to be installed between the door frame and the sliding door panel on the cabin body to achieve the sliding cooperation and sealing relationship between the sliding door panel and the door frame. The special feature of the device is that the device includes:

[0010] The track adopts a segmented variable structure, including a horizontal fixed section, a movable hinged section and a movable slope section;

[0011] The roller is mounted on the top of the sliding door panel through a connecting plate and is adapted to roll on the track;

[0012] A power unit drives the movable slope section connected to the track to achieve a position state change of the movable slope section;

[0013] When the roller is in rolling contact with the horizontal fixed section of the track, the sliding door panel is in an open state, and a predetermined gap distance is maintained between the sliding door panel and the door frame;

[0014] When the roller reaches the movable hinge part of the track, the power unit pulls the movable slope section of the track inward, allowing the roller to enter the movable slope section, thereby releasing the predetermined gap distance between the sliding door panel and the door frame, and sealing the sliding door panel to one side of the door frame.

[0015] The roller adopts a bearing.

[0016] The power unit adopts a cylinder, a hydraulic cylinder or a motor.

[0017] The track, roller and power unit are integrated and assembled in a shell, and the shell is installed on the cabin body through a fixing piece.

[0018] A sealing strip is installed on the door frame.

[0019] The sliding sealing device for the oxygen cabin sliding door of the utility model, by setting the track as a variable and controllable segmented structure and combining the design of the power unit, can more flexibly adjust and adapt the sealing state between the sliding door body and the door frame, which not only optimizes and improves the sealing effect and improves the sealing effect of the cabin door, but also avoids a series of problems such as poor user experience and discomfort caused by instantaneous pressurized sealing.

DETAILED DESCRIPTION

[0025] The utility model is described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] A sliding sealing device for a sliding door of an oxygen cabin comprises a door frame 2 welded to a cabin body 1, and a sliding door panel 3 connected to the cabin body 1 through a hoisting mechanism 4 and forming a sealing relationship with the door frame 2, and a sliding sealing assembly 5, wherein the sliding sealing assembly 5 comprises a plane track 51, a bearing 52 rollingly connected thereto, and a power unit 53, wherein the bearing 52 is connected to the top of the sliding door panel 3 through a bearing fixing plate 53, and the plane track 51 comprises a horizontal fixed section 51a, a movable hinge section 51b, and a movable slope section 51c, wherein the movable hinge section 51b is used to connect the horizontal fixed section 51a and the movable slope section 51c to form a movable hinge relationship between the two. The power unit 53 is installed on the back side of the movable slope section 51c to realize driving control of the position of the movable slope section 51c, and the power unit 53 used in this embodiment is a cylinder. It should be understood that in addition to the cylinder in this embodiment, other power components capable of realizing driving, such as hydraulic cylinders and motors, can also be selected from the prior art. The movable slope section 51c has two movable positions. The first movable position is a horizontal position, that is, it is horizontally connected to the horizontal fixed section 51a to form a plane. At this position, the sliding door panel 3 and the door frame 2 are kept at a predetermined gap through the upper bearing 52 and the horizontal fixed section 51a, that is, the sliding door panel 3 at this position has not reached the closed position. The second movable position is an inclined position, which is used to form a certain slope with the horizontal fixed section 51a, so that the sliding door panel 3 at this position can achieve a sealed contact connection with the door frame 2. When the hoisting mechanism 4 drives the sliding door panel 3 to move to the movable hinge part 51b, the push rod of the power part 53 pulls the movable slope section 51c inward, so that the entire plane track 51 changes from a horizontal straight track to a structure with a straight section in front and a slope in the rear. At this time, when the bearing 52 rolls to this position, it will roll to the movable slope section 51c, thereby driving the sliding door panel 3 to be in sealed contact with the door frame 2.

[0028] Embodiment 2

[0029] The difference between this embodiment and the first embodiment is that the power unit 53 is a motor.

[0030] Embodiment 3

[0031] The difference between this embodiment and the first embodiment is that the power unit 53 is a hydraulic cylinder.

[0032] The sliding sealing device for the oxygen cabin sliding door of the utility model, by setting the track as a variable and controllable segmented structure and combining the design of the power unit, can more flexibly adjust and adapt the sealing state between the sliding door body and the door frame, which not only optimizes and improves the sealing effect and improves the sealing effect of the cabin door, but also avoids a series of problems such as poor user experience and discomfort caused by instantaneous pressurized sealing.
