Description

Technical Field

[0001] The utility model relates to the technical field of oxygen chambers, in particular to a sealing device for a door of an oxygen chamber. Background Art

[0002] An oxygen chamber is a device that can provide high-concentration oxygen. It can increase the environmental pressure so that the human body can inhale more oxygen in the chamber. Oxygen chambers are widely used in the medical field, such as for the treatment of carbon monoxide poisoning, brain damage, burns and other diseases. In addition, oxygen chambers are also used in sports rehabilitation, beauty and body care and other fields.

[0003] The door of the oxygen chamber needs to be sealed to prevent oxygen leakage. In order to ensure the sealing of the oxygen chamber, the door body is usually sliding. In the prior art, when the traditional sliding door body slides, the sealing ring on the door body cannot fit tightly with the door frame. After long-term use, the sealing ring ages, which can easily affect the sealing effect of the oxygen chamber. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a sealing device for the door of an oxygen cabin is proposed. By arranging a slider, a rotating rod and a door body, when the door is closed, the door body is made to be close to the door frame, squeezing the sealing ring to improve the sealing effect. When the door is opened, the door body is pulled to shrink, which can avoid friction between the sealing ring and the inner wall of the cabin during sliding, causing wear of the sealing ring and reducing the service life of the sealing ring.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sealing device for an oxygen cabin door comprises a cabin body, a door frame is arranged on the cabin body, a movable plate is arranged inside the cabin body, a slide groove is provided on the side wall of one end of the movable plate close to the door frame, two symmetrically arranged sliders are slidably connected in the slide groove, two sliders are rotatably connected to a rotating rod, two ends of the rotating rods away from the sliders are rotatably connected to a connecting block, a door body matching the door frame is fixedly connected between the two connecting blocks, a movable mechanism for moving the door body is arranged in the cabin body, and a telescopic mechanism for telescoping the door body is arranged in the slide groove.

[0007] Preferably, the moving mechanism comprises an electric push rod fixedly connected to the inner wall of the cabin, the telescopic ends of the electric push rod are commonly fixedly connected to a fixing block, and the fixing block is fixedly connected to the rear wall of the moving plate.

[0008] Preferably, the telescopic mechanism comprises a double-headed threaded rod rotatably connected between the inner walls at both ends of the slide groove, and the double-headed threaded rod passes through the two sliding blocks and is threadedly connected thereto.

[0009] Preferably, the upper end of the double-threaded rod passes through the inner wall of the slide groove, and a gear is fixedly sleeved on the upper end of the double-threaded rod.

[0010] Preferably, a rack is fixedly connected between the inner walls at both ends of the cabin body, and the rack is meshed with the gear.

[0011] Preferably, a sealing ring is provided on a side wall of one end of the door body close to the door frame, and the sealing ring is made of rubber.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting a slider, a rotating rod and a door body, when closing the door, the moving plate moves toward the door frame, driving the door body to move toward the door frame. Under the action of the rack, the gear rotates, driving the double-headed threaded rod to rotate. The rotation of the double-headed threaded rod drives the sliders meshing with it on both sides to move closer to the middle, pushing the door body to move. When the door body reaches the door frame, the slider moves into place and pushes the door body into the door frame, so that the door body is close to the door frame, squeezing the sealing ring to improve the sealing effect.

[0014] 2. By setting up a telescopic mechanism, when the door is opened, the moving plate drives the door body away from the door frame. Under the action of the rack, the gear rotates, driving the double-headed threaded rod to reverse, thereby driving the sliders on both sides to move to both sides, pulling the rotating rods on both sides to rotate, thereby pulling the door body to retract, which can avoid friction between the sealing ring and the inner wall of the cabin during sliding, causing wear of the sealing ring and reducing the service life of the sealing ring.
