[0002] In complex and potentially dangerous work scenarios such as mining, underground tunnel excavation, and underground utility tunnel construction, sudden disasters such as gas explosions, fires, and collapses may occur at any time, causing a sharp decrease in oxygen content and a rapid increase in the concentration of harmful gases in the work environment. Under such extremely harsh conditions, compressed oxygen self-rescue devices have become the last solid line of defense to protect the lives of workers. They can provide users with clean and sufficient oxygen in a timely manner and effectively isolate harmful gases from the outside world. Compressed oxygen self-rescue device testers are equipment used to test their reliability and stability.
[0003] When using a compressed oxygen self-rescue device detector, it is usually necessary to test multiple compressed oxygen self-rescue devices in succession. Because it is connected to multiple air tubes, and these air tubes need to be inserted and removed multiple times, the air tubes are prone to tangling and bending, resulting in poor gas flow inside the tubes, affecting the accuracy of the test results, and making it inconvenient to store them. Summary of the Invention
[0004] The purpose of this utility model is to provide a portable compressed oxygen self-rescue device detector. By setting a storage slot and a rotatable hose reel on the door, it solves the problem of inconvenient storage and easy tangling of the air hose in existing detectors during use.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023]
[0024] Please refer to Figures 1-4. This utility model is a portable compressed oxygen self-rescue device detector, including a housing 1. An operation panel 2 is fixedly installed inside the housing 1. A door 3 is rotatably fitted to the front end of the housing 1. Several through slots 4 are formed through the outer wall of the door 3. A connecting plate 5 is rotatably fitted between the through slots 4 and their corresponding inner side walls. A hose reel 6 is rotatably fitted to the adjacent side of the connecting plate 5, allowing the air hose to be wound onto the hose reel 6. When it is necessary to use the device to test the compressed oxygen self-rescue device, open the door 3 and then rotate the connecting plate 5 towards the inner wall of the door 3 until it is in place. Then, pull out one end of the air tube and insert it into the corresponding air hole in the operation panel 2. Then rotate the connecting plate 5 in the opposite direction. After it is in place, pull out the other end of the air tube and insert it into the compressed oxygen self-rescue device. In this way, multiple air tubes are separated by various through slots 4 to avoid the air tubes from getting tangled together and to avoid the air tubes from being bent and affecting the gas flow. Several storage slots 7 are opened on the inner wall of the box door 3. The storage slots 7 are fixedly installed between the two inner side walls. Various air tube connectors are placed in the storage slots 7, and the slot plates 8 are used to help fix these connectors.
[0025] Specifically, the door 3 has a sliding insert rod 9 that communicates with the through groove 4. The connecting plate 5 has a fixing hole 10 on its adjacent side that engages with the insert rod 9. One end of the insert rod 9 is fixedly connected to a steering plate 11. A guide groove 12 is formed on the upper surface of the steering plate 11. A connecting rod 13 slides within the guide groove 12. One end of the connecting rod 13 is fixedly connected to a pressure rod 14 that slides with the door 3. A first spring 15 is fixedly installed on the side of the steering plate 11 away from the insert rod 9, located inside the door 3. A second spring 16 is fixedly installed on one end of the pressure rod 14, also located inside the door 3. When the door 3 is closed, the front end of the operating panel 2 presses against each pressure rod 14, causing the pressure rod 14 to retract into the door 3 and compress the second spring 16. Simultaneously, the connecting rod 13 moves along with the pressure rod. 14 moves, so that the connecting rod 13 is in the guide groove 12, thereby applying an oblique thrust to the steering plate 11, causing the steering plate 11 to move to one side. The first spring 15 is stretched, and drives the insertion rod 9 to move in the same direction, thereby inserting the insertion rod 9 into the fixing hole 10, thereby fixing the connecting plate 5. When the box door 3 is opened, the first spring 15 and the second spring 16 begin to rebound, and the pressure rod 14 and the steering plate 11 both begin to move in opposite directions, so that the insertion rod 9 gradually disengages from the fixing hole 10. However, the end of the insertion rod 9 will not completely disengage from the fixing hole 10, so as to avoid the connecting plate 5 and the hose reel 6 from swinging when the box door 3 is turned. Subsequently, when the connecting plate 5 is pulled, the connecting plate 5 can squeeze the arc-shaped end of the insertion rod 9, causing the insertion rod 9 to retract to one side until the insertion rod 9 completely disengages from the fixing hole 10, so as to ensure the safety of the equipment.
[0026] Furthermore, a mounting base 17 is fixedly connected to the bottom of the box body 1. A connecting plate 18 is rotatably fitted to the top of the mounting base 17. A connecting pin 19 is rotatably fitted to the end of the connecting plate 18 away from the mounting base 17. An L-shaped plate 20 is fixedly connected to the inner wall of the box door 3. A sliding groove 21 is opened through one side wall of the L-shaped plate 20, which slides with the connecting pin 19. When the box door 3 is opened, the L-shaped plate 20 will rotate with the box door 3. During this process, the connecting pin 19 slides along the sliding groove 21 and drives the connecting plate 18 to rotate relative to the mounting base 17. When the connecting pin 19 moves to the circular end of the sliding groove 21, the box door 3 is also opened to the maximum angle. The circular end can prevent jamming when closing the box door 3.
[0027] The operation process of this embodiment is as follows: When using this device for testing, first open the box door 3 to cause the first spring 15 and the second spring 16 to rebound, thereby driving the insertion rod 9 to disengage from the fixing hole 10. Then rotate the connecting plate 5 towards the inner wall of the box door 3. After rotating to the correct position, pull out one end of the air tube and insert it into the corresponding air hole in the operation panel 2. Then rotate the connecting plate 5 in the opposite direction. After it is in the correct position, pull out the other end of the air tube and insert it into the compressed oxygen self-rescuer. Then you can press the detection switch on the operation panel 2 to perform the test. After completing the test, remove each air tube from the operation panel 2 and the compressed oxygen self-rescuer, rewrap it on the hose reel 6, and store the connector in the storage slot 7.
