[0029] Combine the following Figure 1 The disassembly tool 10 for the bottle valve according to the embodiment of the utility model is described in detail.

[0030] Reference Figure 1 As shown, according to the disassembly tool 10 of the bottle valve of the embodiment of the utility model, the disassembly tool 10 includes a tool body 1, a plurality of assembly pins 2, a connecting portion 3 and a fastening bolt 4. The plurality of assembly pins 2 are fixedly arranged on the tool body 1, and the plurality of assembly pins 2 are respectively suitable for being inserted into the valve hole of the bottle valve, so that the disassembly tool 10 can be installed on the bottle valve. When the tool body 1 rotates, the assembly pins 2 can drive the bottle valve to rotate in the valve hole, so as to facilitate the disassembly and assembly of the bottle valve. Among them, the assembly pins 2 can be fixedly arranged on the tool body 1 by means of threaded fit, interference fit and other connection methods.

[0031] The connecting portion 3 is fixed to the tool body 1, and the connecting portion 3 is suitable for being assembled with a driving member so that the driving member drives the tool body 1 to rotate. The driving member can be a wrench. It can be understood that when installing or removing the bottle valve, the driving member can cooperate with the connecting portion 3 to limit the position. The driving member can rotate the connecting portion 3 by driving the disassembly tool 10 as a whole. The multiple assembly pins 2 can apply torque to the bottle valve to rotate the bottle valve, thereby realizing the installation or disassembly of the bottle valve. The installation and disassembly operations of the bottle valve are simple. In addition, the multiple assembly pins 2 can limit the bottle valve at multiple positions to improve the stability and reliability of the bottle valve when it rotates. The multiple assembly pins 2 can also reduce the force of a single assembly pin 2, which is conducive to reducing the risk of fracture failure of the assembly pin 2 and increasing the service life of the assembly pin 2. In addition, the disassembly tool 10 is inexpensive.

[0032] The fastening bolt 4 is passed through the tool body 1 and is suitable for connecting with the bottle valve, so as to realize the fixed connection between the disassembly tool 10 and the bottle valve. When the disassembly tool 10 is used to install or disassemble the bottle valve, the disassembly tool 10 can be effectively prevented from being separated from the bottle valve to avoid potential safety hazards.

[0033] According to the disassembly tool 10 for bottle valves in the embodiment of the utility model, a plurality of assembly pins 2 are fixedly arranged on the tool body 1, and the plurality of assembly pins 2 are respectively suitable for being inserted into the valve holes of the bottle valves, and the connecting portion 3 is suitable for being assembled with the driving member so that the driving member drives the tool body 1 to rotate. When the plurality of assembly pins 2 are inserted into the valve holes of the bottle valves and the driving member drives the tool body 1 to rotate, the plurality of assembly pins 2 can apply torque force to the bottle valve to rotate the bottle valve, thereby realizing the installation or disassembly of the bottle valve.

[0034] In some embodiments of the present invention, referring to Figure 1 As shown, the tool body 1 has a first surface 11, and a plurality of assembly pins 2 are arranged on the first surface 11. When the disassembly tool 10 is installed on the bottle valve, the plurality of assembly pins 2 can be simultaneously inserted into the valve hole of the bottle valve, which facilitates the use of the disassembly tool 10. The first surface 11 is the surface of the tool body 1 close to the bottle valve.

[0035] In some embodiments of the present invention, referring to Figure 1 As shown, two adjacent assembly pins 2 are spaced apart to avoid mutual interference between the two adjacent assembly pins 2, ensuring that each assembly pin 2 can be inserted into the valve hole of the corresponding bottle valve. In addition, the spacing between the assembly pins 2 can provide sufficient operating space to facilitate fixing the assembly pins 2 to the tooling body 1.

[0036] In some embodiments of the present invention, a bottle valve having three valve holes is used as an example for explanation. Figure 1 As shown, the first surface 11 of the tool body 1 may be provided with three assembly pins 2 corresponding to the three valve holes one by one, and the three assembly pins 2 are spaced apart in pairs.

[0037] In some embodiments of the utility model, the tooling body 1 has a second surface opposite to the first surface 11, and the connecting part 3 is arranged on the second surface. The driving member can be connected to the connecting part 3 on one side of the second surface of the tooling body 1. When the driving member drives the connecting part 3 to rotate, the driving member can avoid interference with components such as the assembly pin 2 arranged on the first surface 11, so as to facilitate the operation of the driving member.

[0038] In some embodiments of the present invention, at least one of the plurality of assembly pins 2 is detachably connected to the tool body 1, which facilitates the maintenance and replacement of the assembly pin 2, thereby facilitating the maintenance and replacement of the disassembly tool 10. Preferably, the plurality of assembly pins 2 are detachably connected to the tool body 1.

[0039] It can be understood that when at least one of the multiple assembly pins 2 is damaged, the corresponding damaged assembly pin 2 can be removed from the tooling body 1 to separate the assembly pin 2 from the tooling body 1, and the assembly pin 2 can be maintained or replaced individually without maintaining or replacing the entire disassembly tool 10, thereby saving operating time and labor and facilitating the maintenance and replacement of the disassembly tool 10.

[0040] In some embodiments of the present invention, the tool body 1 has a plurality of first mounting holes, and an assembly pin 2 is selectively installed in each first mounting hole to improve the versatility of the disassembly tool 10 .

[0041] It can be understood that when using the disassembly tool 10 to install or disassemble bottle valves of different models and specifications, the assembly pin 2 can be selectively installed in the corresponding first installation hole according to the position of the valve hole of the bottle valve, so that multiple assembly pins 2 can correspond to the positions of the valve holes of bottle valves of different models and specifications one by one. The disassembly tool 10 can be smoothly installed on the bottle valve through the assembly pin 2, thereby improving the versatility of the disassembly tool 10, and the disassembly tool 10 can be applicable to bottle valves of different models and specifications.

[0042] In the related art, bottle valves are disassembled and assembled using special tools prepared by the original factory, which need to be purchased separately and are expensive. However, the disassembly tool 10 according to the embodiment of the utility model has a simple structure, low cost, and high versatility. Bottle valves of different models and specifications can be disassembled and assembled using a set of disassembly tools 10 without using the special tools prepared by the original factory, which is conducive to reducing the disassembly and assembly cost of the bottle valve.

[0043] In some embodiments of the present invention, the connecting portion 3 has a second mounting hole for mounting a driving member, and the driving member can be inserted into the second mounting hole to achieve limited cooperation between the driving member and the connecting portion 3, so that the driving member can drive the connecting portion 3 to rotate.

[0044] In some embodiments of the utility model, the inner wall of the second mounting hole has multiple limiting surfaces, and the multiple limiting surfaces are connected in sequence end to end along the circumference of the second mounting hole, and an angle is formed between two adjacent limiting surfaces. The driving member can be inserted into the second mounting hole and form a limiting fit with the multiple limiting surfaces. When the driving member rotates, it can drive the disassembly tool 10 to rotate. The multiple limiting surfaces can limit the driving member in multiple directions, which is beneficial to improving the stability and reliability of the limitation of the driving member and the connecting part 3, so as to improve the stability and reliability of the driving member when driving the disassembly tool 10 to rotate.

[0045] In other embodiments of the utility model, the outer wall of the connecting part 3 has a plurality of limiting surfaces, and the plurality of limiting surfaces are connected in sequence end to end along the circumference of the connecting part 3, and an angle is formed between two adjacent limiting surfaces. The driving member can be sleeved on the outer wall of the connecting part 3 and form a limiting fit with the plurality of limiting surfaces. When the driving member rotates, the disassembly tool 10 can be driven to rotate. The plurality of limiting surfaces can limit the driving member in multiple directions, which is beneficial to improving the stability and reliability of the limiting of the driving member and the connecting part 3, so as to improve the stability and reliability of the driving member when driving the disassembly tool 10 to rotate.

[0046] In a specific embodiment of the present invention, the outer peripheral wall of the connecting portion 3 has six limiting surfaces connected end to end in sequence, the angle between two adjacent limiting surfaces may be 120°, and the driving member may be an external hexagonal socket wrench.

[0047] In some embodiments of the present invention, referring to Figure 1 As shown, there is at least one fastening bolt 4, which can be passed through the tool body 1 and connected to the bottle valve, so that the disassembly tool 10 is fixed to the bottle valve. When the disassembly tool 10 is used to install or disassemble the bottle valve, the disassembly tool 10 can be effectively prevented from being separated from the bottle valve to avoid potential safety hazards. Preferably, there are multiple fastening bolts 4, which can be passed through the tool body 1 and connected to the bottle valve to improve the stability and reliability of the connection between the disassembly tool 10 and the bottle valve.

[0048] The connection part 3 and the tool body 1 are integrally formed, and the connection between the connection part 3 and the tool body 1 does not need to be connected by fasteners or welding, which is conducive to reducing the assembly difficulty of the disassembly tool 10, shortening the production cycle of the disassembly tool 10, improving the production efficiency of the disassembly tool 10, and reducing the number of parts of the disassembly tool 10, which is conducive to the lightweight design of the disassembly tool 10 and facilitates the processing and manufacturing of the disassembly tool 10. Among them, the connection part 3 and the tool body 1 can be integrally formed by forging.

[0049] In some embodiments of the utility model, the tool body 1 has at least one third mounting hole, the third mounting hole can be constructed as a through hole, the bottle valve has a threaded hole threadedly matched with the fastening bolt 4, the fastening bolt 4 can pass through the third mounting hole and threadedly match with the threaded hole of the bottle valve, so that the disassembly tool 10 is fixedly connected to the bottle valve.

[0050] In some embodiments of the utility model, the bottle valve is a hydrogen bottle valve, which is installed on a hydrogen storage bottle. When replacing the hydrogen bottle valve, it is necessary to ensure that the gas in the hydrogen storage bottle is completely discharged. The original hydrogen bottle valve can be disassembled from the hydrogen storage bottle by disassembly tool 10, and then the new hydrogen bottle valve can be installed on the hydrogen storage bottle by disassembly tool 10, thereby completing the replacement of the hydrogen bottle valve.

[0051] It can be understood that when the original hydrogen cylinder valve is disassembled from the hydrogen storage bottle, the position of the assembly pin 2 of the disassembly tool 10 can be adjusted according to the position of the valve hole of the original hydrogen cylinder valve, and the assembly pin 2 can be inserted into the valve hole, and then the fastening bolt 4 is passed through the tool body 1 and screwed into the threaded groove of the original hydrogen cylinder valve with a torque of 10±2N*m to prevent the disassembly tool 10 from being separated from the original hydrogen cylinder valve, and then the driving part is connected to the connecting part 3, and the driving part drives the disassembly tool 10 to rotate counterclockwise to disassemble the original hydrogen cylinder valve from the hydrogen storage bottle. Finally, the fastening bolt 4 is loosened and the assembly pin 2 is pulled out of the valve hole to separate the disassembly tool 10 from the original hydrogen cylinder valve.

[0052] When installing the new hydrogen cylinder valve on the hydrogen storage bottle, the position of the assembly pin 2 of the disassembly tool 10 can be adjusted according to the position of the valve hole of the new hydrogen cylinder valve, and the assembly pin 2 can be inserted into the valve hole. Then, the fastening bolt 4 is passed through the tool body 1 and screwed into the threaded groove of the new hydrogen cylinder valve with a torque of 10±2N*m to prevent the disassembly tool 10 from separating from the new hydrogen cylinder valve. Then, the driving part is connected to the connecting part 3, and the driving part drives the disassembly tool 10 to rotate clockwise to install the new hydrogen cylinder valve on the hydrogen storage bottle. Finally, the fastening bolt 4 is loosened and the assembly pin 2 is pulled out of the valve hole to separate the disassembly tool 10 from the new hydrogen cylinder valve, completing the replacement operation of the hydrogen cylinder valve.

[0053] According to the disassembly tool 10 of the embodiment of the utility model, the disassembly tool 10 can be combined with the appearance and structural characteristics of the bottle valve and be forged with high-strength steel. The high-strength assembly pin 2 is used as a way to apply torque force, and the fastening bolt 4 can be used to fix the disassembly tool 10 to the bottle valve. When using a large torque to disassemble or install the bottle valve, the risk of separation of the disassembly tool 10 and the bottle valve can be effectively reduced to avoid safety hazards. The disassembly tool 10 as a whole has the advantages of small size, light weight, low cost, high versatility and high efficiency. The disassembly tool 10 can meet the operational requirements of on-site installation and replacement of bottle valves.
