Under the meshing connection between the worm gear 512 and the worm gear 513, the rotation of the worm gear 512 can cause the worm wheel ring 513 to drive the rotating ring 3 to rotate.
[0033] Reference Figure 3 - Figure 5The circular block 2 is equipped with a feeding mechanism 6 and a lubrication mechanism 7 at its top. The feeding mechanism 6 includes a slide 611 and a spring A612. The slide 611 is formed on the outer wall of the circular block 2 and provides a reciprocating pressing position for the extrusion block 613. One end of the spring A612 is fixedly connected to the inner wall of the slide 611. After the extrusion block 613 has been pressed, the spring A612 can reset the extrusion block 613. The other end of the spring A612 is fixedly connected to the extrusion block 613. Under the action of the rebound force of the spring A612, the extrusion block 613 can expel the fire extinguisher can. The outer wall of the extrusion block 613 is slidably connected to the inner wall of the slide groove 611. The top of the circular block 2 is provided with an installation groove and a moving groove. The lubrication mechanism 7 includes a lubricating oil tank 711, which is fixedly connected to the inner wall of the installation groove. The lubricating oil tank 711 stores lubricating oil to ensure subsequent oil spraying. A protrusion 712 is slidably connected to the inner wall of the moving groove. The outer wall of the protrusion 712 is connected to the lubricating oil tank 711 through a sealing piston rod 714. The protrusion 712 is squeezed by the rotating ring 3, which can push the sealing piston rod 714 to move. The outer wall of the sealing piston rod 714... Both ends are fixedly connected to sealing balls 715, which can seal the oil outlet. An oil guide pipe 716 is fixedly connected to the side of the lubricating oil tank 711 near the protrusion 712. When the sealing balls 715 are no longer sealing the oil outlet, the lubricating oil inside the lubricating oil tank 711 can flow into the oil guide pipe 716 through the oil outlet. An oil outlet is opened on the inner wall of the lubricating oil tank 711 near the protrusion 712, serving as the path for oil to exit the lubricating oil tank 711. One end of the oil guide pipe 716 is fixedly connected to an oil nozzle 717, which can spray oil through the oil guide pipe 716. A small amount of oil is sprayed out from inside, and the oil outlet is connected to the other end of the oil guide pipe 716.

[0034] Reference Figure 1 - Figure 2The pushing mechanism 8 also includes a hydraulic rod A812, which is fixedly connected to the front of a conveyor 811 via a positioning plate. The positioning plate can position and install the hydraulic rod A812 on the conveyor 811. The hydraulic inner rod of the hydraulic rod A812 is fixedly connected to a pushing block 813, which can push the material tray 912 to move. A feeding mechanism 9 is provided on the rotating ring 3, which includes a feeding port 911. The feeding port 911 is opened at the top of the rotating ring 3. The material tray 912 can be pushed to the inner wall of the feeding port 911 by the pushing mechanism 8. The material tray 912 is inserted into the feeding port 911, and fire extinguishers that need to be pressure tested can be placed into the inner wall of the material tray 912 for feeding. The inner wall of the inlet 911 is provided with a roller groove, and a ball bearing 913 is rotatably connected to the inner wall of the roller groove. The ball bearing 913 can easily transport the material tray 912 to the inner wall of the inlet 911. The base 1 is also provided with a pressure detection mechanism 10. The pressure detection mechanism 10 includes a support frame 1011, which is fixedly connected to the top right side of the base 1. The support frame 1011 can provide the main support for the pressure detection mechanism 10. A hydraulic rod B1012 is fixedly connected to the top of the support frame 1011. The hydraulic rod B1012 can push the pressure detection machine 1013 to move up and down. The bottom end of the hydraulic inner rod of the hydraulic rod B1012 is fixedly connected to the pressure detection machine 1013. The pressure detection machine 1013 can perform pressure detection on the fire extinguisher.
[0035] Working principle: When pressure testing the fire extinguisher, the loading pallet 912 containing the fire extinguisher canister is placed on the front conveyor 811 with the handle of the loading pallet 912 facing the hydraulic rod A812. The conveyor 811 transports the loading pallet 912. By activating the hydraulic rod A812, the hydraulic inner rod of the hydraulic rod A812 pushes the pusher block 813 to move linearly. The pusher block 813 pushes the loading pallet 912 to the upper loading port 911. The ball bearings 913 rotate on the inner wall of the groove, facilitating the transport to the loading port 911. By activating the motor 511, the output end of the motor 511 drives the fixedly connected worm gear 512 to rotate, thereby driving the outer wall of the worm gear 512 to rotate. The meshing worm gear ring 513 rotates, driving the rotating ring 3 fixedly sleeved on the inner wall to rotate. The rotating ring 3 performs circumferential motion, allowing the material tray 912 to be moved directly below the pressure testing mechanism 10. By activating the hydraulic rod B1012, the inner rod of the hydraulic rod B1012 pushes the pressure testing machine 1013 to descend. The pressure testing machine 1013 can perform pressure testing on the fire extinguisher canisters. Unqualified fire extinguisher canisters can have their material tray 912 pulled out at the pressure testing mechanism 10 using the handle. Qualified fire extinguisher canisters can be rotated again by the rotating mechanism 5 to move the material tray 912 to the rear conveyor 811, thus completing the pressure test.
[0036] When the rotating ring 3 rotates, the extrusion block 613 is located on the inner wall of the chute 611 and is in a compressed state, while the spring A612 is in a compressed state. When the material tray 912 is located at the back loading port 911, the rebound force of the spring A612 will push the extrusion block 613. The extrusion block 613 can push qualified fire extinguisher canisters onto the back conveyor 811, thereby facilitating the collection of qualified fire extinguisher canisters and improving overall work efficiency. When the rotating ring 3 rotates, it will also extrude the protrusion 712 and the spring B713. 2. The sealing ball 715 can be pushed by the sealing piston rod 714, and the sealing ball 715 no longer seals the oil outlet. The lubricating oil inside the lubricating oil tank 711 can flow out through the oil outlet and the oil guide pipe 716, and finally be sprayed out in a small amount through the oil nozzle 717, so as to lubricate the connection between the rotating ring 3 and the extrusion block 613, thereby reducing the wear of the extrusion block 613 and helping to extend the service life of the extrusion block 613. When the rotating ring 3 is in a stationary state, the rebound force of the spring B713 can reset the protrusion 712 to facilitate the next lubrication.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
