Description

Technical Field

[0001] The utility model belongs to the field of oxygen cabin doors, and in particular relates to a sealing structure for an oxygen cabin door. Background Art

[0002] Hyperbaric oxygen chamber is a special medical equipment for high-pressure oxygen therapy. According to the different pressurized media, it is divided into air pressurized chamber and pure oxygen pressurized chamber. The application range of hyperbaric oxygen chamber is very wide. It is mainly used clinically for the treatment of anaerobic infection, CO poisoning, gas embolism, decompression sickness, ischemic-hypoxic encephalopathy, brain trauma, cerebrovascular disease, etc.

[0003] Since the hyperbaric oxygen chamber needs a relatively large entrance and exit for entry and exit, a relatively large sealing structure is required for sealing. Since the door and the body of some hyperbaric oxygen chambers are opened and closed by a hinged connection structure and sealed by a rubber ring, the sealing effect is average, which affects the sealing of the hyperbaric oxygen chamber. Moreover, during treatment, since there is no locking assembly, the door of the hyperbaric oxygen chamber can be opened from the outside, thereby affecting the treatment. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an oxygen chamber door sealing structure which can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: an oxygen cabin door sealing structure, including a fixed cylinder, the fixed cylinder is fixedly connected to the door body, the door body is rotatably connected to the cabin body, the cabin body is provided with a placement groove around the door body, an airbag is fixedly connected in the placement groove, the airbag is equidistantly arranged in a circle facing the door body, the door body is provided with a groove matching the protrusion, a latch is slidably connected in the fixed cylinder, an extrusion box is fixedly connected to the side of the cabin body located at the door body, part of the airbag is located in the extrusion box, a movable plate is slidably connected in the extrusion box, the movable plate is abutted against the airbag, the latch extends into the extrusion box and abuts against the movable plate, an opening is provided at the end of the latch away from the extrusion box, and a fixing rod used in conjunction with the opening of the latch is fixedly connected to the door body.

[0006] In order to prevent the airbag from being damaged, further, the airbag is a wear-resistant rubber bag.

[0007] In order to facilitate better opening of the door body, further, one end of the movable plate away from the airbag is connected to the squeeze box through a contraction spring.

[0008] In order to facilitate more stable movement of the movable plate, further, T-shaped slots are symmetrically opened in the extrusion box, and T-shaped blocks are slidably connected in the T-shaped slots, and the T-shaped blocks are fixedly connected to the movable plate.

[0009] In order to lock and fix the hyperbaric oxygen chamber when it is not in use, the fixing cylinder is further arranged symmetrically, a fixing block is fixedly connected to the side of the chamber body away from the inside of the chamber, the fixing block is symmetrically arranged with the extrusion box, a groove for cooperating with an adjacent pin is provided on the fixing block, and an opening is provided on the end of the fixing rod away from the chamber body.

[0010] In order to increase the friction force and prevent the latch from slipping out of the extrusion box and the limit block, further, a friction layer is arranged in the fixing cylinder.

[0011] After adopting the above technical scheme, compared with the existing sealing structure, the utility model moves the pin in the fixed cylinder so that the pin enters the extrusion box for fixing, thereby preventing the door body from being opened by people outside during treatment and affecting the treatment effect. The pin is used to push the moving plate in the extrusion box to squeeze the airbag, so that the protrusion of the airbag is saturated, and the airbag is abutted against the door body and the cabin body for sealing, which effectively improves the practicality.

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] Embodiment 1:

[0022] Reference Figure 1-Figure 5 A sealing structure for an oxygen cabin door includes a fixed cylinder 6, which is fixedly connected to a door body 2, which is rotatably connected to a cabin body 1, a placement groove is provided around the door body 2, an air bag 3 is fixedly connected in the placement groove, a plurality of protrusions are equidistantly arranged on a circle of the air bag 3 facing the door body 2, a groove matching the protrusion is provided on the door body 2, a latch 7 is slidably connected in the fixed cylinder 6, an extrusion box 8 is fixedly connected to the cabin body 1 on one side of the door body 2, part of the air bag 3 is located in the extrusion box 8, a movable plate 5 is slidably connected in the extrusion box 8, the movable plate 5 is abutted against the air bag 3, the latch 7 extends into the extrusion box 8 and abuts against the movable plate 5, an end of the latch 7 away from the extrusion box 8 is provided with an opening, and a fixing rod 4 used in conjunction with the opening of the latch 7 is fixedly connected to the door body 2.

[0023] The gas in the airbag 3 is unsaturated. When treatment is needed in the hyperbaric oxygen chamber, the door body 2 is rotated to be parallel to the cabin body 1, and then the latch 7 is moved in the fixed cylinder 6, so that the latch 7 enters the extrusion box 8 for fixation. The latch 7 enters the extrusion box 8 to push the movable plate 5 to move, squeeze the airbag 3, and make the extruded airbag 3 saturated, and then the bulge of the airbag 3 is inflated to saturation, and the airbag 3 is abutted against the door body 2 and the cabin body 1 for sealing. When the treatment is over, the movable latch 7 leaves the extrusion box 8, and the airbag 3 loses the pressure of the movable plate 5. When the door body 2 is rotated, the protrusion of the airbag 3 is squeezed, pushing the movable plate 5 back, and the door body 2 is opened, and the hyperbaric oxygen chamber can be left. Compared with the existing sealing structure, the latch 7 is moved in the fixed tube 6 to make the latch 7 enter the squeezing box 8 for fixation, thereby preventing the door body 2 from being opened by outsiders during treatment and affecting the treatment effect. The latch 7 is used to push the movable plate 5 in the squeezing box 8 to squeeze the airbag 3, so that the protrusion of the airbag 3 is saturated, and the airbag 3 is abutted against the door body 2 and the chamber body 1 for sealing, which effectively improves the practicality.

[0024] Embodiment 2:

[0025] Reference Figure 1-Figure 5, an oxygen cabin door sealing structure, which is basically the same as Example 1, and further, the airbag 3 is a wear-resistant rubber bag to prevent the airbag 3 from being damaged during the squeezing process.

[0026] The end of the movable plate 5 away from the airbag 3 is connected to the squeeze box 8 through the contraction spring 9. After the first latch 7 is removed from the squeeze box 8, the contraction spring 9 can move the movable plate 5 back, thereby causing the airbag 3 to lose pressure and restore the unsaturated state, which helps the door body 2 to open better.

[0027] The extrusion box 8 is symmetrically provided with T-slots, in which T-blocks 11 are slidably connected. The T-blocks 11 are fixedly connected to the movable plate 5. By moving the T-blocks 11 in the T-slots, the movable plate 5 can be effectively moved more stably.

[0028] The fixing cylinder 6 is symmetrically arranged, and a fixing block 10 is fixedly connected to the side of the cabin body 1 away from the cabin. The fixing block 10 is symmetrically arranged with the extrusion box 8. A groove used in conjunction with the adjacent latch 7 is opened on the fixing block 10. An opening is opened at the end of the fixing rod 4 away from the cabin body 1. When the hyperbaric oxygen chamber is not needed, the sliding latch 7 enters the fixing block 10, and then the latch 7 is turned down to make the fixing rod 4 enter the opening of the latch 7. When the fixing rod 4 enters the opening of the latch 7, the cabin door is locked to prevent someone from entering when the hyperbaric oxygen chamber is not needed and causing damage to the hyperbaric oxygen chamber.

[0029] A friction layer is provided inside the fixed tube 6 to increase the friction force, so that the latch 7 can move more smoothly inside the fixed tube 6 .

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
