Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher inflation technology, and in particular to a fire extinguisher inflation device. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool containing chemicals used to extinguish fires. Fire extinguishers are a common fire prevention facility. After a fire extinguisher is used up, it needs to be refilled with nitrogen for reuse to improve the utilization rate of the fire extinguisher bottle.

[0003] Most existing inflation devices involve placing the fire extinguisher directly on one side of the device, and then manually connecting the inflation head of the nitrogen delivery pipe to the extinguisher's connector. This manual connection method increases the workload of the workers. Furthermore, the fire extinguisher lacks protective features during inflation, which can easily lead to explosions of substandard fire extinguishers, posing a safety hazard. Therefore, these devices are not convenient for inflation and use, and thus fail to meet customer needs.

[0004] Therefore, those skilled in the art have provided a fire extinguisher inflation device to solve the problems mentioned in the background art. Utility Model Content

A guide plate 13 is fixedly connected to the right side of the rectangular plate 6. A guide groove 14 that works with the guide plate 13 is opened on the right side of the inner cavity of the drive box 3. The outer surface of the guide plate 13 is slidably connected to the inner surface of the guide groove 14. Slide rails 15 are fixedly connected to the front and rear positions on the left side of the vertical plate 2. The outer surface of the slide rails 15 is slidably connected to the inner surface of the lifting plate 8. A pressure gauge 16 is connected to the left side of the inflation tube 12. The pressure gauge 16 is located above the explosion-proof frame 10. A valve 17 is provided on the outer surface of the inflation tube 12. The valve 17 is located above the pressure gauge 16. An anti-slip pad is fixedly connected to the bottom of the counterweight base plate 1. An inspection plate 18 is fixedly installed on the front of the drive box 3 by screws.

[0033] In this embodiment: the present invention, by setting up a counterweight base plate 1, a vertical plate 2, a drive box 3, a servo motor 4, a screw 5, a rectangular plate 6, a drive plate 7, a lifting plate 8, an inflation head 11, and an inflation pipe 12, can facilitate the lifting, docking, and inflation of the fire extinguisher. By setting up an explosion-proof frame 10, the fire extinguisher can be protected against explosions. By setting up the above structure, it is easy to use for inflation protection, thereby meeting the user needs of customers, avoiding potential safety hazards, and effectively reducing the labor intensity of workers.

[0034] Example 2:

[0035] Reference Figure 2 and Figure 4 The limiting component 9 includes a limiting cylinder 901, the bottom of which is fixedly connected to the connection of the lifting plate 8, and a rubber gasket 902 is fixedly connected to the inner surface of the limiting cylinder 901.

[0036] In this embodiment: By setting a limiting cylinder 901 and a rubber gasket 902, the present invention can facilitate the insertion and positioning of the fire extinguisher.

[0037] The implementation principle of this utility model is as follows: During use, the operator connects the inflation tube 12 to the external gas cylinder. Then, the operator electrically connects the device to the mains power. When the fire extinguisher needs to be inflated, the operator inserts the fire extinguisher into the inner cavity of the rubber gasket 902 inside the limiting cylinder 901, thus achieving insertion and positioning of the fire extinguisher. Next, the operator activates the external controller of the servo motor 4, causing the output end of the servo motor 4 to drive the screw 5 to rotate threadedly on the inner surface of the rectangular plate 6. This causes the rectangular plate 6 to drive the drive plate 7 to move upwards. Simultaneously, the drive plate 7 drives the lifting plate 8 to slide upwards on the outer surface of the slide rail 15. This causes the lifting plate 8 to drive the limiting cylinder 901 and the rubber gasket 902 to move upwards, thereby... The limiting cylinder 901 causes the fire extinguisher to move upward and connect with the inflation head 11, thus achieving the docking of the fire extinguisher and the inflation head 11. At the same time, the explosion-proof frame 10 can shield and protect the fire extinguisher in the event of an explosion during inflation, preventing injury. Next, the operator turns the valve 17 to open the inflation pipe 12, allowing the gas in the external gas cylinder to enter the fire extinguisher's inner cavity through the inflation pipe 12 and the inflation head 11. Meanwhile, the pressure gauge 16 displays the pressure in the fire extinguisher's inner cavity. When the pressure in the fire extinguisher's inner cavity reaches the specified inflation value range, the operator turns the valve 17 in the opposite direction to close the inflation pipe 12, stopping the inflation of the fire extinguisher.

[0038] Next, the staff restarted the external controller of the servo motor 4, causing the output end of the servo motor 4 to drive the screw 5 to rotate in the reverse thread on the inner surface of the rectangular plate 6. This caused the rectangular plate 6 to drive the drive plate 7 to move downward. At the same time, the drive plate 7 drove the lifting plate 8 to slide downward on the outer surface of the slide rail 15. This caused the lifting plate 8 to drive the limiting cylinder 901 and the rubber gasket 902 to move downward. As a result, the limiting cylinder 901 drove the fire extinguisher downward away from the explosion-proof frame 10, making it easier for the staff to remove and unload it. This device is simple to operate and easy to inflate for protective use, thus meeting the needs of customers, avoiding potential safety hazards, and effectively reducing the labor intensity of the staff.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
