Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an oxygen cabin with a cantilevered rotating outward-opening door. Background Art

[0002] With the development of medical technology, hyperbaric oxygen chambers have gradually entered people's horizons. Many wealthy people are scrambling to buy them to experience the benefits of hyperbaric oxygen chambers. Especially after the epidemic, the importance of oxygen inhalation has increased, and home micro-pressure oxygen has also entered people's horizons and begun to enter thousands of households. The user group of home micro-pressure oxygen is often the elderly, whose mobility is relatively limited. The existing oxygen chamber doors are mostly metal doors, with only relatively small observation windows or even no observation windows. It is impossible to directly observe the working status and the user's status in the oxygen chamber in the first time. The small and enclosed space will make the user feel stuffy and hot, and may have some physical and psychological side effects. In addition, the doors of oxygen chambers are mainly inward-opening doors, and most of them are all-metal doors. Generally, there are two forms: hinged and locked doors and sliding doors. They are relatively bulky, laborious to open and close, inconvenient to enter and exit the cabin, and are not conducive to the miniaturization and lightweight of the cabin. It has formed certain obstacles and restrictions on the oxygen chamber going upstairs and entering the house. The inward-opening door occupies a certain space in the cabin, which is not conducive to rapid escape from the cabin. Utility Model Content

[0030] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] Example 1

[0032] See also Figures 1 to 9 This embodiment provides an oxygen cabin with a cantilevered rotating outward-opening door, including a cabin body, a cabin door 1, a hatch frame 2, a cabin door frame 3, a rotating mechanism 4, a cabin door rotation limiting slider 41, a cantilever 42, a cantilever slide 43, an anti-rotation limiting mechanism 5, a limiting plate 51, a limiting spring 52, a buffer spring 6 and an auxiliary protection spring 7. Among them, the rotating mechanism functions to rotate the cabin door, and the anti-rotation limiting mechanism functions to prevent the cabin door from rotating after opening.

[0033] Specifically, the hatch 1 is connected to the cabin body, a toothed door frame 3 is provided on the periphery of the hatch 1, a toothed hatch frame 2 is provided on the cabin body, and the teeth of the hatch frame 2 and the teeth of the hatch frame 3 are engaged and separated, thereby realizing the hatch opening and closing.

[0034] At the same time, the door 1 is provided with a rotating mechanism 4 and an anti-rotation limiting mechanism 5. The rotating mechanism 4 includes a door rotation limiting slider 41, a cantilever 42 and a cantilever slide groove 43. Among them, the door 1 and the cantilever 42 are connected by a swivel (not shown in the figure), and the switch rotation of the door 1 is realized by the swivel. In this embodiment, the swivel is a bearing, and the inner and outer rings of the bearing are fixedly connected to the door 1 and the cantilever 42 respectively, so as to realize the relative rotation of the door 1 and the cantilever 42. A rotating shaft (not shown in the figure) is provided at the far end of the cantilever 42 to be connected to the cabin body, and the axial rotation movement of the cantilever 42 relative to the cabin body is realized by the rotating shaft.

[0035] The door rotation limit slider 41 is arranged on the door frame 3, the cantilever slide slot 43 is arranged on the cantilever, and the size of the cantilever slide slot 43 matches the tooth size of the hatch frame 2. The door rotation limit slider 41 can slide up and down in the cantilever slide slot 43, and when the door 1 rotates to the upper and lower end positions of the cantilever slide slot 43, the door frame 3 can be engaged with the hatch frame 2 or separated freely.

[0036] In addition, the anti-rotation limiting mechanism 5 includes a limiting plate 51, and a limiting spring 52 is installed at the bottom of the limiting plate 51. The limiting spring 52 is in a compressed state and an extended state when the cabin door 1 is opened and closed, respectively, so that the limiting plate 51 leaves or is located at the position of the cabin door frame 3, which is used to limit the rotation of the cabin door 1 relative to the cantilever 42, that is, to prevent the cabin door 1 from rotating relative to the cantilever 42 when it is opened.

[0037] At the same time, the hatch 1 is provided with a buffer spring 6 at the rotating shaft, and an auxiliary protection spring 7 is provided at the rear end of the hatch frame 3. In the present embodiment, the buffer spring 6 and the auxiliary protection spring 7 are both gas springs, and the buffer spring 6 is a damping gas spring. The arrangement of the two springs can better realize the labor-saving opening and closing of the hatch, and reduce the inertial force caused by the closing of the heavy-weight hatch. In other embodiments, air pressure, hydraulic pressure or electric struts can also be used to assist in opening the door, which is not limited by the present invention. Among them, the hatch 1 is a fully transparent outward-opening hatch, and the size and shape of the transparent door panel can be adjusted, which is not limited by the present invention.

[0038] The working principle of the oxygen cabin with a cantilevered rotating outward-opening door provided by the utility model is as follows.

[0039] During the assembly stage, the hatch 1 adopts a cantilever handle, and the center of the hatch itself rotates based on the cantilever 42. The hatch opening and closing is realized by the rotation of the hatch 1 itself around the center and the rotation of the cantilever handle around the rotation axis. When the hatch 1 rotates to the cantilever slide slot 43 to open the door (lower limit), the toothed structure of the hatch frame 3 can smoothly enter and exit the toothed structure of the hatch frame 2; when the hatch 1 rotates to the cantilever slide slot 43 to close the door (upper limit), the teeth of the hatch frame 2 and the teeth of the hatch frame 3 are engaged and closed.

[0040] The utility model is provided with an anti-rotation limit mechanism 5 which prevents the cabin door from rotating after it is opened. When the cabin door 1 is closed, the cabin body presses the anti-rotation limit mechanism 5 to leave the cabin door frame 3, loosening the restriction on the rotation of the cabin door 1. At this time, the cabin door 1 can rotate, and the tooth-shaped engagement completes the closing of the cabin door; when the cabin door 1 is opened, the anti-rotation limit mechanism 5 leaves the cabin body and is free from the cabin body pressure. Under the action of the limit spring 52 at the bottom of the limit plate 51, the limit plate 51 rebounds to the position of the cabin door frame 3, restricting the cabin door 1 from rotating at will, thereby avoiding door closing failure and tooth-shaped collision.

[0041] In addition, the hatch 1 is provided with a buffer spring 6 for assisting rotation at the rotating shaft. When the handle of the operating arm 42 is used to open the hatch 1, the buffer spring 6 is compressed. When it is compressed to the shortest designed stroke position, the hatch 1 continues to be opened, the buffer spring 6 releases the compression force, and the hatch 1 is assisted to continue to open to the maximum opening angle. At this time, the hatch 1 is completely opened, and the hatch 1 will not close automatically under the support of the buffer spring 6 unless the hatch 1 is manually controlled to be closed; when the handle of the operating arm 42 is used to close the hatch 1, the buffer spring 6 is compressed. When it is compressed to the shortest designed stroke position, the hatch 1 continues to be closed, the buffer spring 6 releases the compression force, and the hatch 1 is assisted to continue to close. When it is about to be closed, the buffer spring 6 plays a damping role, so that the hatch 1 slowly completes the closing.

[0042] The rear end of the door frame 3 is also provided with an auxiliary protection spring 7 for assisting rotation. When the door 1 rotates to open, the auxiliary protection spring 7 is compressed. When the door 1 rotates past the horizontal state and continues to rotate, the auxiliary protection spring 7 releases the compression force to assist the door frame 3 to rotate and open to the end of the cantilever slot 43 in the cantilever 42. When the door 1 rotates to close, the auxiliary protection spring 7 rotates past the horizontal state and continues to rotate, the auxiliary protection spring 7 releases the compression force to assist the door 1 to lock to the end of the cantilever slot 43 in the cantilever 42. When the door 1 is rotated to open or closed, the auxiliary protection spring 7 will support the door 1 and prevent it from rotating and moving.

[0043] The buffer spring 6 utilizes the elasticity of the gas spring to assist the opening and closing of the hatch 1 during the process of opening and closing the hatch. When the buffer spring 6 is insufficiently elastic or its elasticity disappears, since the buffer spring 6 is a damping gas spring, its damping effect can prevent the hatch from opening and closing suddenly when closing.

[0044] During the use stage, when the hatch door 1 is opened, the hatch door 1 is rotated (clockwise) to the limit position, the tooth shape of the hatch frame 3 and the tooth shape of the hatch frame 2 change from engagement to separation, the handle of the hatch cantilever 42 is rotated around the axis, the hatch door 1 is disengaged from the hatch frame 2, the anti-rotation limit mechanism 5 rebounds to the hatch frame 3, and the hatch door 1 is opened. At this time, the hatch door 1 cannot rotate around itself, and the user can enter and exit the cabin.

[0045] When closing the hatch 1, the handle of the cantilever 42 on the hatch 1 is rotated around the axis, the teeth of the hatch frame 3 are buckled into the teeth of the hatch frame 2, the hatch 1 rotates the anti-rotation limit mechanism 5 to leave the hatch frame 3, the hatch 1 rotates around its own center (counterclockwise) to the limit, the teeth of the hatch frame 3 and the teeth of the hatch frame 2 bite into each other to form a barb, thereby locking the hatch 1 to prevent the hatch 1 from opening when the high pressure in the cabin is high.

[0046] In summary, the above-mentioned implementation modes are not limitative implementation modes of the present invention, and any modification or equivalent deformation made by technicians in this field on the basis of the essential content of the present invention is within the technical scope of the present invention.
