Technical Field

[0001] This utility model relates to a spiked wheel wrench, and more particularly to a multi-functional wrench specifically for pressure regulation in gas systems. Background Technology

[0002] The gas equipment used for gas supply in urban gas systems is large and has many pipelines. The densely distributed gas pipes are connected to numerous small components such as gas meters and pressure regulating pipes. When adjusting the pressure of the gas system or replacing gas meters, it is very inconvenient for workers to operate with ordinary wrenches due to the narrow space between the gas pipes. Moreover, gas meter valves have high precision and usually require two types of wrenches to be used for adjustment or disassembly. Workers need to carry multiple types of wrenches, making the operation difficult and inefficient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a multi-functional wrench for gas system pressure regulation that is simple in structure, small in size, easy to operate, efficient, flexible and highly applicable.

[0004] This utility model discloses a multi-functional wrench for regulating the pressure of a gas system, comprising a ratchet drive head, a first handle, and a second handle. One end of the first handle and the second handle are detachably connected to the side wall of the ratchet drive head, and the other end of the first handle and the second handle are respectively provided with a first open-end wrench head and a second open-end wrench head.

[0005] This utility model discloses a multi-functional wrench specifically for regulating the pressure of a gas system, wherein both the first handle and the second handle are threadedly connected to a ratchet drive head.

[0006] This utility model discloses a multi-functional wrench for regulating the pressure of a gas system, wherein both the first open-end wrench head and the second open-end wrench head have V-shaped openings, and the two V-shaped openings have different angles.

[0007] This utility model relates to a multi-functional wrench specifically for regulating the pressure of a gas system, wherein the inner walls of the V-shaped openings of both the first open-end wrench head and the second open-end wrench head are provided with serrations.

[0008] This utility model discloses a multi-functional wrench for regulating the pressure of a gas system, which also includes an adapter. The ratchet drive head is provided with a ratchet, and the adapter is detachably sleeved on the ratchet.

[0009] This utility model discloses a multi-functional wrench specifically for regulating the pressure of a gas system, wherein the adapter is a universal joint sleeve connector.

[0010] The difference between this utility model and the prior art is that the ratchet drive head of this utility model has a first handle and a second handle that can be flexibly assembled and have an adjustable length. Moreover, both handles are provided with open wrench heads at the ends, so they can be used as independent wrenches. In addition, it is also equipped with a universal joint socket connector that can increase the length of the socket wrench.

[0011] This utility model discloses a multi-functional wrench for regulating pressure in a gas system and its application method, which has at least the following beneficial effects:

[0012] (1) This multi-functional wrench has a simple structure, small size and flexible assembly, and is suitable for use in narrow spaces and in situations where multiple wrenches are used together, reducing the difficulty of operation for workers and improving work efficiency.

[0013] (2) Each handle can be used as an independent wrench. When two wrenches are needed to adjust the pressure of the gas meter or to disassemble it, remove the first handle or the second handle. The removed handle can be used as a separate wrench, and the other handle and ratchet drive head can be used as a ratchet wrench.

[0014] (3) Both open-end wrench heads on the two handles are V-shaped openings. The width of the V-shaped opening gradually increases from the inside to the outside, which can be used for bolts of more sizes.

[0020] like Figure 1As shown, this utility model discloses a multi-functional wrench for regulating the pressure of a gas system, including a ratchet drive head 01, a first handle 02 and a second handle 03. One end of the first handle 02 and the second handle 03 can be detachably connected to the side wall of the ratchet drive head 01. The other end of the first handle 02 and the second handle 03 are respectively provided with a first open wrench head 21 and a second open wrench head 31.

[0021] This multi-functional wrench is mainly used for adjusting gas pressure in gas systems and for disassembling and assembling small components such as gas pressure gauges.

[0022] The ratchet drive head 01 is equipped with a ratchet 11, a reversing component 13, a braking block, and a spring. When in use, the socket wrench is directly inserted into the ratchet 11, and the rotation direction of the ratchet 11 is adjusted by the reversing component 13 to disassemble or adjust the bolts in the gas system.

[0023] Both the first handle 02 and the second handle 03 are connected to the side wall of the ratchet drive head 01 and are detachable, allowing workers to flexibly assemble them as needed and choose between single-handle or double-handle operation. The first handle 02 and the second handle 03 are preferably arranged opposite each other, facilitating force application during double-handle operation.

[0024] In addition, the ends of the first handle 02 and the second handle 03 away from the ratchet drive head 01 are respectively welded with a first open wrench head 21 and a second open wrench head 31. With this configuration, each handle can be used as an independent wrench. When it is necessary to adjust the pressure or disassemble / assemble the gas meter with two wrenches, the first handle 02 or the second handle 03 is removed. The removed handle is used as a separate wrench, and the other handle and the ratchet drive head 01 are used as a ratchet 11 wrench. By removing the open wrench head on the handle to hold the bolt at the connection between the component to be disassembled or adjusted and the gas pipeline, the bolt on the component to be disassembled or adjusted is turned by the ratchet 11 wrench, so as to realize the disassembly and assembly of components such as the gas meter and the adjustment of the gas pressure.

[0025] This multi-functional wrench has a simple structure, small size, and can be flexibly assembled. It is suitable for use in confined spaces and in situations where multiple wrenches are used together, reducing the difficulty of operation for workers and improving work efficiency. It has certain promotional value.

[0026] like Figure 1 As shown, both the first handle 02 and the second handle 03 are threadedly connected to the ratchet drive head 01.

[0027] Both the first handle 02 and the second handle 03 have external threads at the ends away from the open-end wrench head. The ratchet drive head 01 has two threaded holes on its side wall that match the first handle 02 and the second handle 03. The two handles are detachably connected to the ratchet drive head 01 through threads. The threaded connection is not only easy to disassemble and secure, but also allows the handle length to be adjusted by rotating the handle as needed, enhancing the flexibility and adaptability of the multi-functional wrench.

[0028] like Figure 1 As shown, both the first open-end wrench head 21 and the second open-end wrench head 31 have V-shaped openings, and the angles of the two V-shaped openings are different. The inner walls of the V-shaped openings of both the first open-end wrench head 21 and the second open-end wrench head 31 are provided with serrations 22.

[0029] Due to the complex environment of the gas system, there are not only a large number of bolts, but also bolts of different sizes. If the first open-end wrench head 21 and the second open-end wrench head 31 are made of a specific model of ordinary open-end wrench head, they can only meet the needs of a single type of bolt, which has certain limitations.

[0030] To overcome this limitation, both open-end wrench heads on the handles are V-shaped. The unique feature of the V-shaped opening is that the width gradually increases from the inside to the outside. This design allows the multi-functional wrench to be used for bolts of more sizes. At the same time, the inner wall of the V-shaped opening is provided with serrations 22 for engaging the bolt, which can effectively limit or loosen the bolt rotation.

[0031] To further improve the applicability of the multi-functional wrench, the V-shaped openings of the two open-end wrench heads are set to different opening angles (e.g., the opening angle of the first open-end wrench head 21 is 15 degrees, and the opening angle of the second open-end wrench head 31 is 30 degrees), thereby further expanding the applicability of the multi-functional wrench.

[0032] In addition, multiple first handles 02 and second handles 03 can be set, and the opening angle of the open wrench head on each handle is different. When workers actually operate, they can select the handle that matches the bolt diameter range for disassembly or adjustment, which greatly enhances the flexibility and adaptability of the multi-functional wrench.

[0033] like Figure 1 As shown, the multi-functional wrench also includes an adapter 04. A ratchet 11 is provided inside the ratchet drive head 01, and the adapter 04 is detachably sleeved on the ratchet 11. The adapter 04 is a universal joint sleeve connector 41.

[0034] The ratchet 11 is provided with a connecting part 12 for connecting with the adapter 04 or a socket wrench. The adapter 04 has grooves at its upper and lower ends that match the connecting part 12 of the ratchet 11, and a protrusion 42 for insertion onto the socket wrench. When working in narrow and winding environments, it is often encountered that the socket wrench is too short to be fitted onto the bolt after being inserted into the ratchet 11. By connecting the adapter 04, the problem of the socket wrench being unable to be fitted onto the bolt due to its limited length can be solved. During operation, the adapter 04 is first fitted onto the connecting part 12 of the ratchet 11, then the socket wrench is fitted onto the protrusion 42 of the adapter 04, indirectly increasing the length of the socket wrench. Finally, the socket wrench is fitted onto the bolt, realizing the installation, removal, and adjustment of bolt tightness, thus improving work efficiency.

[0035] To further improve the flexibility of the multi-functional wrench in confined spaces, the adapter 04 adopts a universal joint socket connector 41. This design not only increases the connection length of the socket wrench, but also allows for flexible adjustment of the bending angle of the universal joint socket connector 41 in narrow and tortuous spaces, enabling variable angle operation. This enhances the flexibility and applicability of the multi-functional wrench, thereby improving work efficiency.

[0036] This multi-functional wrench can be used not only in gas systems but also in other fields. It can be connected to various types of socket wrenches (such as hexagonal sockets, universal socket wrenches, etc.) to disassemble and assemble bolts of corresponding models, making it of great significance for promotion.
