[0019] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only some, not all, of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0020] Figure 1 This is a front view of a tightening device for a high-pressure gas cylinder 2 provided by an embodiment of the present invention; Figure 2 This is a left side view of a tightening device for a high-pressure gas cylinder 2 provided by an embodiment of the present invention; Figure 3 2 is a right side view of a tightening device for a high-pressure gas cylinder 2 provided in an embodiment of the present invention; Figures 1 to 3 As shown,

[0021] A tightening device for a high-pressure gas cylinder 2 comprises:

[0022] 1. Bracket 1, used to fix the body of high-pressure gas cylinder 2;

[0023] Bracket 1 is a crucial component of the present invention, primarily used to secure high-pressure gas cylinder 2 and prevent displacement during operation. Specifically, bracket 1 comprises two U-shaped clips, one positioned above and one below high-pressure gas cylinder 2, and two bolts, one of which passes through one side of the two U-shaped clips and is tightened with a nut, while the other passes through the other side of the two U-shaped clips and is tightened with a nut to secure the body of high-pressure gas cylinder 2.

[0024] The bolts and nuts are used to fix the high-pressure gas cylinder 2 through the U-shaped clip to ensure that the high-pressure gas cylinder 2 does not move when the joint 4 is tightened, avoiding dangers caused by inaccurate positioning.

[0025] Furthermore, the U-shaped card includes: a first connecting plate, a second connecting plate and a third connecting plate connected in sequence;

[0026] The first connecting plate and the third connecting plate are both straight plate structures; the second connecting plate is an arc-shaped plate structure; the inner surface of the second connecting plate is in contact with the outer surface of the high-pressure gas cylinder 2; the bolts are used to pass through the first connecting plate and the third connecting plate.

[0027] Specifically, one of the bolts passes through the two first connecting plates in sequence to connect one side of the two U-shaped clips and fix them through nuts; the other bolt passes through the two third connecting plates in sequence to connect the other side of the two U-shaped clips and fix them through nuts.

[0028] The inner surface of the curved plate mates with the outer surface of the high-pressure gas cylinder 2, providing better fit and stability. The two straight plates are connected by bolts, ensuring that the U-shaped clamp firmly secures the high-pressure gas cylinder 2. This design improves the fit and stability of the high-pressure gas cylinder 2 and the bracket 1, ensuring that the high-pressure gas cylinder 2 does not shift during operation.

[0029] Furthermore, a plurality of the brackets 1 are provided; all the brackets 1 are arranged at intervals along the body of the high-pressure gas cylinder 2 .

[0030] In a preferred embodiment, multiple brackets 1 are evenly spaced along the body of the high-pressure gas cylinder 2 to enhance the stability of the brackets 1 in securing the cylinder. If the high-pressure gas cylinder 2 is long or heavy, the use of multiple brackets 1 can better distribute the weight and external forces of the high-pressure gas cylinder 2, ensuring that the joint 4 of the high-pressure gas cylinder 2 remains stable during the tightening process, and avoiding improper operation due to changes in the position of the high-pressure gas cylinder 2.

[0031] 2. Wrenches: Two wrenches 3 are provided, each used to clamp the connectors 4 at both ends of the high-pressure gas cylinder 2;

[0032] The wrench 3 is a key component of the present invention, used to tighten the connector 4 of the high-pressure gas cylinder 2 using torque. Each wrench 3 is designed to match the size of the connector 4 of the high-pressure gas cylinder 2 and can provide sufficient force to tighten the connector 4 during operation. Two wrenches 3 are used to secure the connector 4 at each end of the high-pressure gas cylinder 2.

[0033] 3. A shaft sleeve 5, one end of which is connected to one of the wrenches 3;

[0034] In an optional embodiment, a shaft handle is provided on one side of the wrench 3 ; one end of the shaft sleeve 5 is sleeved on the shaft handle of one of the wrenches 3 .

[0035] Sleeve 5 is designed to increase the torque applied to joint 4 by extending the lever arm. One end of sleeve 5 is connected to the handle of one of the wrenches 3. This increases the torque applied by extending the lever arm, ensuring the tightening operation is complete. The length of sleeve 5 is adjusted based on the required torque.

[0036] Furthermore, the shaft sleeve 5 is made of a seamless steel pipe, and the inner diameter of the steel pipe matches the shaft handle of the wrench 3.

[0037] 4. Anti-rotation fixture 6, used to fix the other wrench 3;

[0038] The anti-rotation clamp 6 is provided with a clamping groove for clamping and fixing the shaft handle of another wrench 3.

[0039] The anti-rotation clamp 6 is used to fix the other wrench 3 to ensure that the high-pressure gas cylinder 2 does not rotate or move during the tightening process. It firmly clamps the shaft of the wrench 3 through the clamping groove, ensuring that when the connector 4 at one end of the high-pressure gas cylinder 2 is tightened, the other wrench 3 always remains in a fixed state, preventing operational errors or rotation of the high-pressure gas cylinder 2.

[0040] 5. A wire lock buckle 7, one end of which is connected to the other end of the shaft sleeve 5;

[0041] The wire lock buckle 7 is a connecting component used to connect the shaft sleeve 5 to the crane scale 8.

[0042] 6. A hanging scale 8, connected to the other end of the wire lock 7, for displaying the force applied to the shaft sleeve 5;

[0043] The crane scale 8 is a key component of the present invention, used to measure the traction force applied to the shaft sleeve 5 in real time. The connection between the crane scale 8 and the wire lock 7 can provide a direct value of the applied force, which the operator can use to adjust the traction force of the lifting device to ensure that the desired torsional moment is achieved.

[0044] 7. A lifting device 9 connected to the hanging scale 8 and used for applying traction to the shaft sleeve 5.

[0045] Lifting equipment 9 is used to apply the actual traction force, controlling the force's magnitude based on feedback from the crane scale 8 to ensure the desired torque is accurately achieved. This traction force is typically applied using equipment such as cranes and jacks, with the magnitude of the traction force adjusted based on the data from the crane scale 8 to ensure the desired effect is achieved.

[0046] Furthermore, the traction force applied by the lifting device 9 to the shaft sleeve 5 is determined according to the torsional moment required by the joint 4 of the high-pressure gas cylinder 2 and the length of the shaft sleeve 5 .

[0047] The specific formula is: Torsional moment = force × lever arm

[0048] Among them, the lever arm is the length of the sleeve 5, the force is the traction force applied by the lifting equipment 9 to the sleeve 5, and the specific value is displayed by the hanging scale 8. The torsional torque is the torsional torque required to tighten the connector 4 of the high-pressure gas cylinder 2.

[0049] Beneficial effects of the present invention:

[0050] The present invention provides a simple and efficient tightening device for the connector 4 of a high-pressure gas cylinder 2. Through a rational design, multiple device components are effectively combined, allowing operators to easily complete the tightening operation of the connector 4 of a high-pressure gas cylinder 2. The device of the present invention provides operators with a simple and safe tightening solution, especially in emergency or on-site work environments. Tightening the connector 4 of a high-pressure gas cylinder 2 requires applying a large torque, and traditional manual or simple equipment often cannot guarantee accuracy and stability, thus posing a safety hazard. With the device of the present invention, operators can precisely control the applied torque to ensure that the connector 4 is tightened within the specified torque, avoiding leakage or cylinder damage caused by overtightening or undertightening, thereby significantly improving the safety of the cylinder. Furthermore, the design of the present invention can automatically adjust the applied traction force according to the required torque of the connector 4 of the high-pressure gas cylinder 2. With the real-time data displayed by the crane scale 8, operators can quickly determine whether the required torque has been achieved, thus avoiding the trouble of manual testing and repeated adjustments, greatly improving work efficiency and operation time. This device not only quickly completes the tightening operation, but also accurately controls the torque, saving the time and labor costs associated with traditional methods.
