Description

Technical Field

[0001] This utility model relates to the field of oxygen chamber technology, and in particular to a novel oxygen chamber door. Background Technology

[0002] Currently, there are two main types of hatches on the market: revolving doors with manual closing and sliding doors with pneumatic closing. Sliding doors with pneumatic closing use a cylinder for hard contact pressing, such as... Figures 5 to 7 As shown, the sliding door is slidably connected to the sliding door track via a sliding door slider. A ball bearing is located at the end of the sliding door track, resting on an inclined base. The contact surface between the inclined base and the ball bearing is inclined. When the cylinder presses the door, the cylinder pressing plate clamps the sliding door slider, the sliding door track, and the entire sliding door inwards. The ball bearing, subjected to inward pressure, rolls inwards and upwards on the inclined base, causing the entire sliding door to move inwards and press against the sealing gasket. When the cylinder releases, the cylinder pressing plate opens, and under the weight of the sliding door slider, the sliding door track, and the entire sliding door, the ball bearing rolls downwards to reset, causing the sliding door to return to its original position and disengage from the seal. This pressing process can easily cause some damage to the door body, and the clamping process can generate noise, resulting in a poor user experience. Utility Model Content

[0003] The purpose of this invention is to provide a novel oxygen chamber door that solves the problems of easy damage to the door body, noise generation, and poor user experience associated with the cylinder-pressurized sliding door in the prior art.

Detailed Implementation

[0023] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 4 As shown, this embodiment discloses a novel oxygen chamber door, including a door frame plate 1, an entrance 2 on the door frame plate 1, and a chamber door 4 on one side of the entrance 2. The chamber door 4 is slidably connected to the door frame plate 1 via a guide slide assembly 7. The chamber door 4 is poweredly connected to a drive assembly 3, which is fixedly connected to the door frame plate 1. In this embodiment, the chamber door 4 is provided with a handle 4-1.

[0025] The drive assembly 3 includes a motor 3-1, which is fixedly connected to the door frame plate 1. The output end of the motor 3-1 is fixedly connected to a lead screw 3-2, which is rotatably connected to the door frame plate 1. A connecting block 3-3 is threadedly connected to the lead screw 3-2, and the connecting block 3-3 is fixedly connected to the hatch 4.

[0026] The guide rail assembly 7 includes a guide rail 7-1, which is fixedly connected to the door frame plate 1. There are two guide rails 7-1, located at the upper and lower ends of the hatch 4, respectively. Guide sliders 7-2 are slidably connected to each guide rail 7-1, and the guide sliders 7-2 are fixedly connected to the hatch 4.

[0027] When motor 3-1 rotates, it drives lead screw 3-2 to rotate, which in turn drives connecting block 3-3 to move horizontally. Connecting block 3-3 drives hatch 4, which opens or closes under the action of guide rail 7-1 and guide slider 7-2. Motor 3-1 is electrically connected to an external controller.

[0028] An inflatable sealing ring 5 is provided around the outer periphery of the doorway 2. The inflatable sealing ring 5 is located between the hatch 4 and the door frame plate 1, and it makes a sealing contact with the hatch 4 and the door frame plate 1. In this embodiment, the inflatable sealing ring 5 includes a sealing ring body 5-1, which is a hollow structure. The sealing ring body 5-1 is fixedly connected to the door frame plate 1 by a sealing ring fixing plate 5-3. An inflation port 5-2 is provided on the sealing ring body 5-1, which is connected to an external inflation device. The inflation device is an air pump.

[0029] A position detection sensor 6 is installed on the door frame plate 1, located on both sides of the maximum travel of the hatch 4. In this embodiment, two position detection sensors 6 are provided, one located at the maximum closing travel of the hatch 4 and the other located at the maximum opening travel of the hatch 4. Both position detection sensors 6 are electrically connected to an external controller.

[0030] The position detection sensor 6, located at the maximum closing stroke, transmits the closing information of the hatch 4 to the controller. The controller then sends a command to the inflation device to inflate and seal the hatch. Similarly, the position detection sensor 6, located at the maximum opening stroke, transmits the opening information of the hatch 4 to the controller. The controller then sends a command to motor 3-1 to stop motor 3-1, at which point the door 2 is in the open state.

[0031] The operation process of this utility model is as follows:

[0032] First, a command is sent to the controller via the door-closing button. The controller then starts motor 3-1, which drives the lead screw 3-2 to rotate, thereby closing the hatch 4 via the connecting block 3-3. When the position sensor 6, located at the maximum closing stroke of hatch 4, detects that hatch 4 is closed, it transmits a signal to the controller. The controller then sends a command to the external inflation device to inflate and seal the hatch. When it is necessary to open the hatch, a command is sent to the controller via the door-opening button. The controller then controls the inflation device to deflate the hatch. After deflation is complete, motor 3-1 is restarted in reverse to open the hatch.

[0033] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
