Description

Technical Field

[0001] This utility model relates to the technical field of fire extinguisher production equipment, specifically a fire extinguisher valve assembly device. Background Technology

[0002] Portable carbon dioxide fire extinguishers are a common type of fire extinguishing equipment, primarily used to extinguish initial fires. They offer advantages such as rapid extinguishing speed, non-conductivity, and no residue, and are widely used in scenarios involving electrical equipment, precision instruments, and oil fires. During the production of portable carbon dioxide fire extinguishers, the valve needs to be assembled onto the extinguisher. However, in current technology, the extinguisher cylinder is typically first placed on a workbench for fixation, and then the valve is manually placed onto the nozzle. Finally, a torque wrench is used to tighten the valve, completing the installation. However, manual valve installation is slow, significantly reducing the production efficiency of portable carbon dioxide fire extinguishers. Utility Model Content

[0044] Example 1

[0045] like Figure 3-6As shown, in this embodiment, the conveying mechanism 200 includes: a C-shaped plate 210, two rotating rollers 220, and a motor 230. The bottom of the C-shaped plate 210 is fixedly connected to the inner bottom surface of the connecting shell 110. A clamping assembly is provided on the C-shaped plate 210.

One end of the rotating rod 250 is fixedly connected to a second bevel gear 251, and the second bevel gear 251 meshes with the first bevel gear 241. The other end of the rotating rod 250 is fixedly connected to a screw 252. The bottom of the four moving plates 260 is screwed to the corresponding screw 252. One side of the moving plate 260 is fixedly connected to a limit plate 261. The limiting plate 261 is slidably inserted into the U-shaped plate 210. Four fixing brackets 270 are respectively fixedly connected to the top of the corresponding moving plate 260. Four clamping plates 280 are respectively fixedly connected to the corresponding fixing brackets 270. A rubber pad 281 is fixedly connected to one inner side wall of the clamping plate 280. The tightening mechanism 300 includes: a rectangular plate 310, two cylinders 320, a motor 340, a double-acting screw 360, a motor 370, two connecting blocks 380, and two connecting plates 390. The bottoms of the two cylinders 320 are fixedly connected to the top of the connecting shell 110. The output end of the cylinders 320 is fixedly connected to the bottom of the rectangular plate 310. The motor 340 is fixed to the top of the rectangular plate 310. The output end of the motor 340 passes through the side wall of the rectangular plate 310 and is fixedly connected to a rotating plate 350. The bottom of the moving plate 350 has a limiting groove 351, and both ends of the top surface of the limiting groove 351 have sliding grooves 352. The bidirectional lead screw 360 is rotatably connected to the rotating plate 350. The two ends of the bidirectional lead screw 360 are respectively located inside the two sliding grooves 352. Both ends of the bidirectional lead screw 360 are screwed to a moving block 361, and the moving block 361 is slidably connected to the interior of the corresponding sliding groove 352. The motor 370 is fixedly connected to one side of the rotating plate 350. The output end of the motor 370 passes through the side wall of the rotating plate 350 and is fixedly connected to one end of the bidirectional lead screw 360. The tops of the two connecting blocks 380 are slidably connected to the limiting grooves 351. The tops of the connecting blocks 380 are fixedly connected to the bottoms of the corresponding moving blocks 361. The bottom of the connecting blocks 380 has multiple circular grooves 381.Two connecting plates 390 are located at the bottom of two connecting blocks 380. Each connecting plate 390 has a connecting notch 391 on an adjacent side. A round tube 392 is fixedly connected to the top of each connecting plate 390, and the round tube 392 is slidably inserted into the corresponding round groove 381. Multiple compression springs 393 are fixedly connected to the top of each connecting plate 390, and the top of each compression spring 393 is fixedly connected to the inner top surface of the corresponding round groove 381.

[0046] In this embodiment, by starting motor 230, the corresponding rotating roller 220 is driven to rotate, thereby causing the conveyor belt 221 to rotate. The rotating conveyor belt 221 facilitates the transport of the fire extinguisher bottle. When the fire extinguisher bottle is transported to the appropriate position, the top of the conveyor belt 221 is supported by the support plate 222 to prevent the top of the conveyor belt 221 from collapsing during the transport of the fire extinguisher bottle, which would affect the transport effect. Then, by starting motor 240... Motor 240 drives bevel gear 241 to rotate, which meshes with four bevel gears 251, causing four rotating rods 250 and screw 252 to rotate. Limiting plate 261 limits the movement of moving plate 260, allowing movement of moving plate 260, fixing frame 270, clamping plate 280, and rubber pad 281. This facilitates clamping and fixing of fire extinguisher cylinders, and can clamp and fix fire extinguisher cylinders of different sizes. Furthermore, by placing the valve... At the top of the fire extinguisher cylinder, the cylinder retracts via cylinder 320, causing rectangular plate 310 and rotating plate 350 to move downwards to an appropriate position. Simultaneously, motor 370 rotates the double-acting screw 360, causing moving block 361, connecting block 380, and connecting plate 390 to move. This causes the inner wall of connecting notch 391 to press against the end of the valve. Then, motor 340 drives rotating plate 350 and the two connecting blocks 361... The two connecting plates 390 and 80 rotate to facilitate tightening of the valve. The circular groove 381 and circular tube 392 allow the connecting plates 390 to move with the downward movement of the valve, ensuring the tightening effect of the tightening mechanism 300 on the valve. This, in turn, ensures the assembly effect of the tightening mechanism 300 on the valve. By adjusting the positions of the two connecting blocks 380 and the two connecting plates 390, the tightening mechanism 300 can assemble and fix valves of different sizes.

[0047] like Figure 4 As shown, in this embodiment, telescopic plates 330 are fixedly connected to the four corners of the bottom of the rectangular plate 310, and the bottom of the telescopic plates 330 is fixedly connected to the top surface of the connecting shell 110.

[0048] In practice, four telescopic plates 330 are used to assist in limiting the rectangular plate 310.

[0049] Example 2

[0050] Based on Embodiment 1, in order to improve the conveying effect of the conveying mechanism 200 on the fire extinguisher bottle and prevent the fire extinguisher bottle from moving during conveying, which would be detrimental to the clamping assembly in clamping and fixing the fire extinguisher bottle.

[0051] like Figure 5 As shown, in this embodiment, the limiting component includes: multiple cylinders 120 and an L-shaped plate 130. One end of each of the multiple cylinders 120 is fixedly connected to the inner sidewall of the connecting shell 110. One inner sidewall of the L-shaped plate 130 is fixedly connected to the output end of the corresponding multiple cylinders 120. The top of the L-shaped plate 130 is in contact with the inner top surface of the connecting shell 110. A connecting hole 131 is provided on one side of the L-shaped plate 130.

[0052] In practice, by activating cylinder 120, the L-shaped plate 130 is moved to the appropriate position, and the two L-shaped plates 130 are used to limit the fire extinguisher bottle conveyed on the conveyor belt 221, preventing the fire extinguisher bottle from moving during conveying. This makes it easier for the clamping assembly to pass through the two connecting holes 131 to clamp and fix the fire extinguisher bottle, ensuring the effectiveness of the conveying mechanism 200.
