[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 8As shown, the utility model provides an emergency respirator for delivery training, including an emergency respirator 1, wherein a bottom block 2 is fixedly installed inside the emergency respirator 1, a discharging chute 3 and a feeding chute 4 are provided inside the bottom block 2, a feeding mechanism and a base 7 are provided inside the feeding chute 4, an oxygen tank 8 is placed inside the base 7, an inner cavity 9 is provided inside the base 7, a movable clamping block 10 is movably installed inside the inner cavity 9, a second spring 11 is elastically connected between the right end of the movable clamping block 10 and the inner wall of the inner cavity 9, a positioning block 12 is movably installed on the inner wall of the inner cavity 9, a third spring 13 is elastically connected between the front of the positioning block 12 and the inner wall of the inner cavity 9, and the right end of the positioning block 12 is provided with a third spring 13. The end of the moving rod 18 passes through the inner cavity 19 and is fixedly installed with a moving block 14. An inner cavity 15 is opened inside the bottom block 2. A pressure switch 16 is fixedly installed on the back of the inner wall of the inner cavity 15. A movable plate 17 is movably installed inside the inner cavity 15. A moving rod 18 is fixedly installed inside the movable plate 17. One end of the moving rod 18 passes through the movable plate 17. The other end of the moving rod 18 passes through the movable plate 17 and extends to the outer surface of the bottom block 2. The outer surface of the moving rod 18 is movably sleeved with a fourth spring 19 located between the front side of the movable plate 17 and the inner wall of the inner cavity 15. A moving block 20 located inside the feeding chute 4 is fixedly installed on the left end of the movable plate 17. A lifting and retracting rod 21 is arranged inside the bottom block 2.

[0024] When the trainee is running low on oxygen, he / she comes to the emergency respirator 1, lifts up the hatch 29, and then pulls the moving rod 18 outward. When the moving rod 18 moves outward, it will drive the movable plate 17 to move together. At this time, the fourth spring 19 is squeezed and is in a compressed state. When the movable plate 17 moves, it will drive the moving block 20 to move together. When the moving block 20 moves to contact the moving block 1 14, it will drive the positioning block 12 to move together through the moving block 14. Then, as the positioning block 12 moves, it will separate from the movable clamping block 10. At this time, the fastening effect of the oxygen tank 8 in the base 7 will be released. The trainee can take out the oxygen tank 8 and put the discarded oxygen cylinder into the base 7. Then the trainee loosens the moving rod 18. Due to the elastic force of the fourth spring 19, the moving rod 18 is reset and hits the pressure switch 16 forward. After hitting the pressure switch 16, the impact signal is transmitted to the PLC, and the lifting and retracting rod 21 is controlled by the PLC to operate. The lifting and retracting rod 21 pushes the base 7 and the exhaust gas oxygen tank 8, so that it moves inside the discharge chute 3 to the guide block 28 for storage.

[0025] Through training, personnel pull the motion rod 18, utilize the movable plate 17 to drive the movable block 20 to move, utilize the movable block 20 to drive the positioning block 12 to disengage from the movable clamping block 10, and then contact the fixing effect of the movable clamping block 10, so as to facilitate the removal of the oxygen tank 8, and then utilize the elastic force of the fourth spring 19 to trigger the lifting and retracting rod 21, so as to store the waste oxygen tank. Compared with the traditional device, this device can realize stable support of the oxygen tank 8 while facilitating the release of the fixation and automatic storage of the discarded oxygen tank.

[0026] Among them, an inner cavity three 22 is opened inside the bottom block 2, and a driving shaft 23 and a driven shaft 24 are rotatably installed inside the inner cavity three 22. The driving shaft 23 and the driven shaft 24 are connected by a transmission belt 25. A push plate 26 is fixedly installed on the outer surface of the transmission belt 25. A motor 27 is fixedly installed inside the bottom block 2, and the output shaft of the motor 27 is fixedly connected to the driving shaft 23.

[0027] When the moving rod 18 hits the pressure switch 16, the PLC will also control the motor 27 to run, and then drive the driving shaft 23, which will drive the push plate 26 to run through the transmission belt 25, and use the push plate 26 to drive the subsequent base 7 to move forward one grid, thereby replacing the position of the previous base 7.

[0028] Through the programming control of PLC, the motor 27 will operate according to the predetermined instructions, and use the power transmission of the push plate 26 to accurately drive the subsequent base 7 to move forward one grid, thereby automatically moving the subsequent material carrying unit to the original position of the previous material carrying unit, realizing automatic loading and replacement of materials. The whole process is efficient and stable, which greatly improves the replacement efficiency of the oxygen tank 8.

[0029] The feeding mechanism includes a vertical plate 5 movably installed inside the feeding chute 4 , and a first spring 6 is fixedly connected between the vertical plate 5 and the inner side surface of the feeding chute 4 .

[0030] At this time, the first spring 6 is in a state of elastic compression. When the current base 7 is replaced, the elastic recovery effect of the first spring 6 drives the subsequent base 7 to be replenished forward, thereby facilitating continuous replacement of the base 7 and improving replacement efficiency.

[0031] A guide block 28 is fixedly mounted on the left end of the bottom block 2 , the top of the guide block 28 is an inclined surface, and a hatch 29 is hinged on the outer surface of the emergency respirator 1 .

[0032] Due to the design of the guide block 28, when the telescopic rod 21 pushes the base 7, the waste oxygen tank 8 is pushed and slides inside the discharge chute 3 to the top of the guide block 28 for collection.

[0033] The outer surface of the movable plate 17 is smooth, and the fourth spring 19 is in a non-tension and non-compression state.

[0034] Due to the design of the movable plate 17, the moving rod 18 can be effectively limited, ensuring that the moving rod 18 and the pressure switch 16 are on the same horizontal line, ensuring that the moving rod 18 and the pressure switch 16 collide smoothly.

[0035] There are six push plates 26 , which are evenly distributed on the outer surface of the transmission belt 25 , and a distance between two adjacent push plates 26 is equal to a length of the base 7 .

[0036] Since the distance between two adjacent push plates 26 is equal to the length of the base 7 , the base 7 can be accurately driven to automatically move forward, while changing the movement direction of the base 7 in the feeding chute 4 .

[0037] The working principle and use process of this utility model:

[0038] When the trainee is running low on oxygen, he / she comes to the emergency respirator 1, lifts up the hatch 29, and then pulls the moving rod 18 outward. When the moving rod 18 moves outward, it will drive the movable plate 17 to move together. At this time, the fourth spring 19 is squeezed and is in a compressed state. When the movable plate 17 moves, it will drive the moving block 20 to move together. When the moving block 20 moves to contact the moving block 1 14, it will drive the positioning block 12 to move together through the moving block 14. Then, as the positioning block 12 moves, it will separate from the movable clamping block 10. At this time, the tightening effect of the oxygen tank 8 in the base 7 will be released. At this time, the trainer can take out the oxygen tank 8 and put the discarded oxygen cylinder into the base 7, and then the trainer loosens the motion rod 18. At this time, due to the elastic force of the fourth spring 19, the motion rod 18 is reset and hits the pressure switch 16 forward. After hitting the pressure switch 16, the impact signal is transmitted to the PLC, and the lifting and retracting rod 21 is controlled by the PLC to operate. The lifting and retracting rod 21 pushes the base 7 and the exhaust gas oxygen tank 8, so that it moves inside the discharge chute 3 to the guide block 28 for storage;

[0039] When the moving rod 18 hits the pressure switch 16, the PLC will also control the motor 27 to run, and then drive the driving shaft 23, which will drive the push plate 26 to run through the transmission belt 25, and use the push plate 26 to drive the subsequent base 7 to move forward one grid, thereby replacing the position of the previous base 7.
