[0002] In the healthcare field, for equipment with circular structures such as hyperbaric oxygen chambers, sterilizers, and some imaging equipment cabins, doors are key components connecting different spaces, and their functionality and convenience have a significant impact on user experience and space utilization efficiency.

[0003] In the current healthcare field, hyperbaric oxygen chambers consist of a chamber body and doors, most of which use sliding or hinged doors. Hinged doors require outward expansion when opened, but hyperbaric oxygen chambers often need to accommodate multiple patients (e.g., multi-patient chambers), making it difficult to meet layout requirements when ward space is limited. Sliding doors require a large space for rotation when opening, which is extremely inconvenient in space-constrained locations. Therefore, there is an urgent need to design a ring-shaped sliding door structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a ring-shaped movable door structure to overcome the aforementioned shortcomings in the prior art.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown in the figure, the present invention provides a circular movable door structure, including an arc-shaped door 1 and a circular track 2. A plurality of roller assemblies 4 are provided on the back of the arc-shaped door 1. The circular track 2 is inserted into the roller assembly 4. The roller assembly 4 includes a roller frame 41 provided on the arc-shaped door 1. Two fixed rollers 42 are provided in the roller frame 41. An adjusting roller 43 is provided on one side of the fixed roller 42. The circular track 2 is located between the fixed roller 42 and the adjusting roller 43. A plurality of power components 6 are provided on the inner surface of the arc-shaped door 1. A plurality of damping components 3 are provided on the circular track 2.

[0026] In this embodiment, a number of roller assemblies 4 are provided on the back of the arc-shaped door 1. The roller assembly 4 adopts a three-roller clamping structure of "double fixed and one adjustable". The annular track 2 is inserted into the roller assembly 4. The roller assembly 4 includes a roller frame 41 set on the arc-shaped door 1. The roller frame 41 is integrally formed from high-strength aluminum alloy 6061-T6. Two fixed rollers 42 are set in the roller frame 41. The fixed rollers 42 are made of bearing steel GCr15 and are matched with deep groove ball bearings to ensure long-term stable operation. An adjustable roller 43 is set on one side of the fixed roller 42. The two fixed rollers 42 and the adjustable roller 43 are distributed at 120° to form a stable three-point clamping system. The annular track 2 is located between the fixed rollers 42 and the adjustable roller 43.

[0027] Specifically, the roller frame 41 is provided with an adjustment groove 44, and the adjustment roller 43 achieves a certain radial displacement through the adjustment groove 44. The adjustment roller 43 slides in the adjustment groove 44 to fix the annular track 2. A fixing screw 45 is provided at the center of the adjustment roller 43, and the adjustment roller 43 is fixed in the adjustment groove 44 by the fixing screw 45.

[0028] In this embodiment, a plurality of power components 6 are provided on the inner surface of the arc-shaped door 1. The power components 6 include a motor base 63 welded to the surface of the arc-shaped door 1. The motor base 63 is welded from steel plate. An output motor 61 is provided on the upper surface of the motor base 63. The output motor 61 is a DC brushless servo motor. A rotating roller 62 is provided on the lower surface of the motor base 63. The outer surface of the rotating roller 62 is covered with a polyurethane elastic layer and the surface is designed with cross-shaped anti-slip grooves to ensure no sliding transmission with the annular track 2. The rotating roller 62 is tightly fitted with the annular track 2. The output shaft of the output motor 61 is connected to the rotating roller 62. The output shaft of the output motor 61 and the rotating roller 62 are connected by an expansion sleeve.

[0029] In this embodiment, a plurality of damping components 3 are provided on the annular track 2. The damping components 3 include mounting rods 31 provided on the annular track 2, and a plurality of sleeves 32 provided on the mounting rods 31. The sleeves 32 have a stepped hole design inside, with the upper part accommodating the push rod 33 and the lower part housing the compression spring 34. The mounting rod 31 contains 3 buffer units, and the sleeves 32 are provided with springs 34. The springs 34 are made of 65Mn spring steel. The push rod 33 is slidably inserted into the sleeves 32, and the springs 34 are located below the push rods 33. When the arc-shaped door 1 is closed, the push rod 33 first contacts the damping baffle 7, and the springs 34 are gradually compressed to form a damping buffer so that the door stops smoothly. This design can reduce the impact force of closing the door, protect the track and door structure, and avoid the risk of pinching.

[0030] In this embodiment, the roller frame 41 is welded with fixing parts 5 on both sides. The fixing parts 5 are made of steel forging and are fixed to the arc-shaped door 1 by M12 high-strength fixing bolts 51. Several fixing bolts 51 are provided on the fixing parts 5. The roller frame 41 is fixed to the arc-shaped door 1 by the fixing bolts 51 on the fixing parts 5.

[0031] In this embodiment, there are two annular tracks 2, and the two annular tracks 2 are located on the back sides of the arc-shaped door 1 respectively. The double annular tracks 2 are formed by cold bending of Q235B hot-dip galvanized steel pipes.

[0032] In this embodiment, the front of the curved door 1 is provided with a handle 11, which makes it convenient for users to manually control the curved door 1. Both sides of the back of the curved door 1 are provided with reinforcing ribs 12 to enhance the structural strength of the curved door 1. The annular track 2 is located on one side of the reinforcing ribs 12 to reduce motion interference. Both ends of the back of the curved door 1 are provided with damping baffles 7, and the surface of the damping baffles 7 is provided with a shock-absorbing rubber layer to further improve the damping and shock absorption effect.

[0033] Working steps: 1. Initial installation: Fix the roller frame 41 to the back of the arc-shaped door 1 with the fixing bolts 51 on the fixing part 5, insert the annular track 2 into the roller assembly 4, adjust the roller 43 to slide in the adjusting groove 44, and adjust its position by fixing screw 45 so that the annular track 2 is tightly located between the fixed roller 42 and the adjusting roller 43 to ensure the stability of the arc-shaped door 1 and the annular track 2. Then, make the rotating roller 62 in the power assembly 6 on the arc-shaped door 1 fit tightly with the annular track 2, and set the mounting rod 31 of the damping assembly 3 on the annular track 2.

[0034] 2. When it is necessary to open or close the arc-shaped door 1, start the output motor 61. The output shaft of the output motor 61 drives the rotating roller 62 to rotate. The rotating roller 62 is in close contact with the circular track 2. Under the action of friction, the rotation of the rotating roller 62 is converted into the circular movement of the arc-shaped door 1 along the circular track 2. At this time, the roller assembly 4 plays a role, rolling along the circular track 2 to assist the arc-shaped door 1 to move smoothly.

[0035] Third, if the curved door 1 encounters an external impact or speed change during its movement, the damping component 3 on the circular track 2 will start to work, slowing down the movement speed and impact force of the curved door 1, so that the curved door 1 can maintain stable operation and avoid affecting the safety and lifespan due to violent shaking.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
