[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figures 1-5 As shown, this utility model provides a clamping device for disassembling and assembling valves of small-capacity gas cylinders, including a base 1. The base 1 has two mounting slots 103, the inner contour of which is straight. The base 1 is provided with a clamping backplate structure 2 and a clamping retractable strap 3 for clamping the gas cylinder; the clamping backplate structure 2 is provided with a strap tightening drive structure 5 for tightening and loosening the clamping retractable strap 3; and the clamping backplate structure 2 is provided with a spacing adjustment structure 6 for adjusting the tension of the clamping retractable strap 3.

[0031] See instruction manual attached Figure 1 and Figure 2 As shown, a vertical plate 101 is fixedly welded onto the base 1. Two support rods 102 are provided on the upper side of the vertical plate 101 for fixing and supporting the clamping back plate structure 2. A bottom limiting support structure 4 is provided on the vertical plate 101 for limiting and supporting the bottom of the gas cylinder. In actual application, the outer contour of the support rod 102 is L-shaped. The support rod 102 is fixedly connected to the vertical plate 101 by bolts.

[0032] See instruction manual attached Figure 1 , Figure 3 and Figure 4 As shown, the clamping back plate structure 2 includes a back plate 201, and the two sides of the back plate 201 are fixedly connected to two support rods 102 by bolts. The back plate 201 has a V-shaped cross-section, and a strap 202 is provided in the V-shaped groove of the back plate 201. Opening slots 203 for passing through the clamping and gathering strap 3 are provided on both sides of the back plate 201 and the strap 202.

[0033] In this embodiment, the clamping backplate structure 2, through the coordinated cooperation of the backplate 201, the adhesive strip 202, and the opening slot 203, achieves the initial precise positioning of the gas cylinder with the help of the V-shaped backplate 201. The adhesive strip 202 protects the small container thin-walled gas cylinder and enhances the anti-slip effect, preventing damage, deformation, and slippage of the gas cylinder. On the other hand, the opening slots 203 on both sides of the backplate 201 and the adhesive strip 202 provide a stable channel for clamping the gathering strap 3, ensuring that the clamping gathering strap 3 can form a circumferential clamping with the backplate 201, providing basic support for the tightening operation of the belt tightening drive structure 5 and the spacing adjustment of the spacing adjustment structure 6.

[0034] See instruction manual attached Figure 2 , Figure 3and Figure 4 As shown, the tightening drive structure 5 includes a first electric push rod 501 fixedly mounted on a back plate 201. A drive plate 502 is fixedly connected to the push rod head of the first electric push rod 501. The drive plate 502 is fixedly connected to both ends of the clamping and tightening strap 3. Two guide shafts 503 are symmetrically distributed on both sides of the first electric push rod 501, with one end of each guide shaft 503 fixedly connected to the back plate 201. The other ends of each guide shaft 503 are slidably connected to guide holes opened at corresponding positions on the drive plate 502. When the tightening drive structure 5 is working, the push rod of the first electric push rod 501 extends and retracts to transmit power to both ends of the clamping and tightening strap 3 through the drive plate 502, causing the clamping and tightening strap 3 to tighten or loosen. Simultaneously, the guide shafts 503 on both sides cooperate with the guide holes of the drive plate to ensure that the drive plate 502 and the tightening strap move along a preset trajectory, avoiding deviation.

[0035] See instruction manual attached Figure 5 As shown, the spacing adjustment structure 6 includes a second electric push rod 602, which is fixedly mounted on the back plate 201 via a fixing seat 601. The second electric push rod 602 is a dual-axis electric push rod, and wheel frames 603 are fixedly connected to the two push rod ends of the second electric push rod 602. Each wheel frame 603 has two rotatable adjusting pulleys 604, and a threading gap is formed between the two adjusting pulleys 604 for the clamping and gathering strap 3 to pass through. In practical applications, the spacing adjustment structure 6 is used to adjust the gathering distance of the clamping and gathering strap 3 to achieve adaptive clamping of small-volume gas cylinders of different diameters. During operation, after the second electric push rod 602 is started, the dual axes synchronously drive the two wheel frames 603 to move closer or further away. The wheel frames 603 drive the internal adjusting pulleys 604 to move synchronously, so that the clamping and gathering strap 3 passing through the gap of the adjusting pulleys 604 adjusts its position accordingly, changing the size of the space enclosed by it and the V-shaped groove on the back plate 201, until it adapts to the diameter of the gas cylinder to be clamped. Meanwhile, by adjusting the rolling friction design of pulley 604, wear on the clamping and winding belt 3 is reduced, ensuring long-term stable operation of the equipment.

[0036] See instruction manual attached Figure 2 and Figure 3As shown, the bottom limiting support structure 4 includes an adjusting groove 401 formed on the upright plate 101. Two parallel guide rods 406 are fixedly installed in the adjusting groove 401. An adjusting slider 402 slides on the guide rods 406. A lifting plate 403 is provided on one side of the adjusting slider 402. A pad 404 is provided on the upper side of the lifting plate 403. A locking bolt 405 is threadedly connected to one side of the adjusting slider 402 to achieve a tight abutment against the guide rods 406. The bottom limiting support structure 4 is used to ensure the stability of the bottom of the gas cylinder and prevent movement during the disassembly and assembly of the cylinder valve. In operation, the locking bolt 405 is loosened first, and the adjusting slider 402 is pushed to slide up and down along the guide rods 406 in the adjusting groove 401, which drives the lifting plate 403 and the pad 404 to adjust their height synchronously until the pad 404 adapts to the bottom support requirements of the current gas cylinder. Then, the locking bolt 405 is tightened to lock the slider position, so that the bottom of the gas cylinder is placed stably on the pad 404, forming the bottom limiting.

[0037] Working principle:

[0038] The base 1 connects to an external workbench or fixed surface through mounting holes 103 to determine the overall position of the equipment and prevent the equipment from shifting during the disassembly and assembly of the gas cylinder. At the same time, the upright plate 101 and the two side support rods 102 on the base 1 provide fixed support for the clamping back plate structure 2. In the bottom limiting support structure 4, the adjusting slider 402 can slide along the guide rod 406 in the adjusting groove 401, driving the lifting plate 403 on one side to adjust up and down. Tightening the set bolt 405 on one side of the adjusting slider 402 makes it tightly abut against the guide rod 406, locking the position of the bottom support structure and preventing the gas cylinder from moving up and down. Thus, when the clamping back plate structure 2 and the clamping strap 3 clamp the gas cylinder, the bottom support of the gas cylinder can be limited, which facilitates the positioning and disassembly of the cylinder valve.

[0039] The spacing adjustment structure 6 is driven by the second electric push rod 602 to adjust the spacing of the clamping strap 3. Specifically, the second electric push rod 602 is fixed to the back plate 201 by the fixing seat 601, and its two push rod ends are respectively connected to the wheel frame 603. According to the diameter of the gas cylinder, the second electric push rod 602 pushes or pulls the wheel frame 603 to adjust the spacing of the two wheel frames 603. The clamping strap 3 passes through the belt-passing gap formed by the two adjusting pulleys 604 in each wheel frame 603. When the wheel frame 603 moves, the adjusting pulleys 604 move synchronously with it, thereby changing the size of the enclosed space between the clamping strap 3 and the back plate 201 to adapt to gas cylinders of different diameters. The tightening drive structure 5 drives the clamping strap 3 to tighten, completing the gas cylinder clamping. Specifically, the first electric push rod 501 is fixed on the back plate 201, and its push rod head is connected to the drive plate 502. Both ends of the clamping strap 3 are fixed to the drive plate 502. When the first electric push rod 501 is activated, its push rod retracts, pulling the drive plate 502 to move closer to the back plate 201. When the drive plate 502 moves, the guide shafts 503 on both sides ensure that the drive plate 502 moves smoothly and avoids deviation. The clamping strap 3 retracts with the drive plate 502, and cooperates with the V-shaped groove of the back plate 201 to tightly clamp the gas cylinder between the back plate 201 and the clamping strap 3, completing the clamping and fixing. At this time, the cylinder valve can be disassembled and assembled.

[0040] After the cylinder valve is disassembled and reassembled, the first electric push rod 501 is activated in reverse to extend its push rod, which drives the drive plate 502 away from the back plate 201, loosens the clamping strap 3, and the gas cylinder can be removed.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
