Description

Technical Field

[0001] This utility model belongs to the field of oxygen chamber technology, specifically an oxygen chamber door including an automatic opening and closing locking mechanism. Background Technology

[0002] Single-person oxygen chambers are relatively low, requiring users to bend their heads when entering for treatment, which is very inconvenient for elderly patients or those with cervical spine problems. Inward-opening doors are difficult to implement due to limited internal space, so outward-opening doors are often used. However, outward-opening doors need to withstand internal pressure when closed, requiring them to be securely locked. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an oxygen chamber door including an automatic opening and locking mechanism. The door is an outward-opening door that can automatically open, close, lock and unlock. Moreover, users can enter the chamber without having to bend down. The door can withstand internal pressure after it is locked.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an oxygen chamber door including an automatic opening and closing locking mechanism, comprising a door body, an electric push rod, and a locking mechanism; the door body is rotatably connected to the oxygen chamber body at the door hinge hole, and slots are arranged on both sides of the door body; the electric push rod can drive the door body to rotate around its door hinge hole; the locking mechanism includes a reduction motor, a synchronous pulley, a synchronous belt, and a locking assembly, the locking assembly including a drive shaft, a torsion spring, an eccentric wheel, a plug rod, a return spring, and a guide seat, the locking motor drives the drive shaft of the locking assembly to rotate through the synchronous pulley and the synchronous belt, the eccentric wheel is coaxially connected to the drive shaft but does not transmit torque, the two ends of the torsion spring are fixed to the drive shaft and the eccentric wheel respectively, the guide seat is fixed on the chamber body, the return spring is located between the plug rod and the guide seat to ensure that the eccentric wheel and one end of the plug rod are always tangent, the drive shaft drives the eccentric wheel to rotate through the torsion spring, thereby causing the eccentric wheel to drive the plug rod to move axially along the guide seat, after the door body is closed, the plug rod can be inserted into the slot to complete the locking.

[0005] The door has an inverted L-shaped structure, and there is ample height space when the door is opened.

[0006] The locking mechanism can be arranged with multiple sets of locking components. The locking components can achieve multi-point linkage locking by correspondingly arranging multiple sets of synchronous pulleys and synchronous belts. The drive shaft of the locking component rotates, causing the torsion spring to elastically drive the eccentric wheel to rotate, and finally drive all the plugs of the plug rods to be inserted into the slots of the door body and fit into the slots, ensuring the effectiveness of multi-point locking.

[0007] The beneficial effects of this utility model are:

[0008] 1) The door adopts an inverted L-shaped structure, so that users can enter the cabin directly without bending down after the door is opened;

[0009] 2) The locking mechanism can use multiple sets of locking components. By arranging corresponding synchronous pulleys and synchronous belts, multi-point synchronous locking can be achieved. The elastic drive of the torsion spring can ensure that the plug of each set of locking components can fit into the slot of the door body, ensuring the effectiveness of locking.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0020] The technical solution adopted by this utility model to solve its technical problem is:

[0021] An oxygen chamber door including an automatic locking mechanism includes a door body 1, an electric push rod 2, and a locking mechanism 3. The door body 1 is rotatably connected to the oxygen chamber body at a door hinge hole, and slots 101 are arranged on both sides of the door body. The electric push rod 2 can drive the door body 1 to rotate around its door hinge hole. The locking mechanism 3 includes a reduction motor 301, a synchronous pulley 302, a synchronous belt 303, and a locking assembly 304. The locking assembly 304 includes a drive shaft 3041, a torsion spring 3042, an eccentric wheel 3043, a plug rod 3044, a return spring 3045, and a guide seat 3046. The reduction motor 301 drives the locking assembly 304 through the synchronous pulley 302 and the synchronous belt 303. When the drive shaft 3041 rotates, the eccentric wheel 3043 is coaxially connected to the drive shaft 3041 without transmitting torque. The two ends of the torsion spring 3042 are fixed to the drive shaft 3041 and the eccentric wheel 3043 respectively. The guide seat 3046 is fixed on the cabin body. The return spring 3045 is located between the insertion rod 3044 and the guide seat 3046 to ensure that the eccentric wheel 3043 and one end of the insertion rod 3044 are always tangent. The drive shaft 3041 drives the eccentric wheel 3043 to rotate through the torsion spring 3045, thereby causing the eccentric wheel 3043 to drive the insertion rod 3044 to move axially along the guide seat 3046. After the door 1 is closed, the plug of the insertion rod 3044 can be inserted into the slot 101 to complete the locking.

[0022] The door 1 has an inverted L-shaped structure, and there is ample height space when the door 1 is opened.

[0023] The locking mechanism 3 can be arranged with multiple sets of locking components 304. The locking components 304 can achieve multi-point linkage locking by correspondingly arranging multiple sets of synchronous pulleys 302 and synchronous belts 303. The drive shaft 3041 of the locking components 304 rotates, causing the torsion spring 3042 to elastically drive the eccentric wheel 3043 to rotate, and finally drive all the plugs of the plug rods 3044 to be inserted into the slot 101 of the door body 1 and fit against the slot 101, ensuring the effectiveness of multi-point locking.
