Description

Technical Field

[0001] This utility model relates to the field of socket wrench technology, and in particular to a socket wrench for replacing the valve before a gas meter. Background Technology

[0002] In existing technology, the tools commonly used by gas industry workers when replacing gas meter valves are mainly adjustable wrenches and fixed wrenches (open-end wrenches).

[0003] When replacing a gas meter valve that malfunctions (leakage, failure, aging, etc.), the process is often hampered by factors such as customer cabinets, partitions, other obstacles, and limited space. Specifically, existing adjustable wrenches require considerable operating space when used with standard DN20 / PN16 ball valves, and force must be applied directly to the valve's tightening point. This requires precise adjustment of the adjusting screw to fit the jaws to the valve's octagonal protrusions. In situations with customer cabinets, partitions, piles of items, limited working space, and insufficient lighting, the adjustable wrench often needs multiple adjustments to accurately engage and prevent slippage, ensuring the force is applied to the valve's octagonal protrusions.

[0004] The open-end wrench jaws also only have two sides for applying force. If there is grease, dust, dirt or other adverse factors on the pipe fittings or valves being replaced, and the old pipe connections have rusted over time, the wrench will often slip and fall off when force is applied, which is time-consuming and laborious.

[0005] The aforementioned defects in the prior art mean that the replacement of gas meter valves is often limited by space, location, and environment, making it impossible to efficiently handle gas meter valve malfunctions. This also greatly reduces the user's work efficiency and increases the risk of injury due to fatigue.

[0006] Therefore, it is necessary to improve and upgrade existing tools used for replacing gas meter valves to reduce the labor intensity of users and improve work efficiency, which has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of the above-mentioned defects of the prior art, the present invention provides a socket wrench for replacing the valve before the gas meter, the purpose of which is to improve the work efficiency of replacing the valve before the gas meter, quickly eliminate safety hazards, and reduce the workload of the user.

[0008] To achieve the above technical objectives, this utility model provides a socket wrench for replacing the valve before a gas meter, including jaws and a handle. The jaws are located at one end of the handle and have a semi-open octagonal structure.

[0009] The inner contour of the jaws can accommodate the octagonal protrusion of the front valve of the gas meter.

[0010] Preferably, the inner surface of the jaws is provided with anti-slip teeth.

[0011] Preferably, the anti-slip teeth are provided on the two inner sides of the jaws near the opening.

[0012] Preferably, the outer contour of the anti-slip teeth is trapezoidal.

[0013] Preferably, the opening direction of the jaws is perpendicular to the length direction of the handle.

[0014] The beneficial effects of this utility model are:

[0015] Due to the above-mentioned structural design, this utility model can fit well with the outer octagon of the gas meter valve, avoiding the drawback of traditional tools that require adjusting the size of the jaw opening, thus saving time and reducing manual labor during the replacement of the gas meter valve; at the same time, it can adapt to the needs of different gas usage locations, and can work well in different conditions such as rusted, dirty, greasy, and dusty pipes, reducing the operational risks caused by slippage and tool drop.

[0020] In the picture: 1 jaws, 2 handles. Detailed Implementation

[0021] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.

[0022] Example:

[0023] like Figures 1-3 As shown, a specific embodiment of a socket wrench for replacing the gas meter valve includes jaws 1 and a handle 2. Jaws 1 are located at one end of the handle 2 and are semi-open octagonal structures. The inner contour of jaws 1 can accommodate the outer octagonal protrusion of the gas meter valve.

[0024] The main innovation of this utility model is as follows:

[0025] The semi-open inner octagon jaw 1 can fit well with the outer octagon of the gas meter valve, avoiding the drawback of traditional tools that require adjusting the size of the jaw opening, thus saving time.

[0026] In one specific embodiment, the handle 2 is 230mm long, and the total length including the jaws 1 and the handle 2 is approximately 275mm.

[0027] The internal configuration of jaw 1 is a semi-regular octagon. The distance between the parallel sides of the regular octagon is 31mm, that is, the diameter of the inscribed circle of the regular octagon is 31mm, which is consistent with the outer octagonal dimension of the valve in front of the instrument.

[0028] Furthermore, the inner surface of the jaw 1 is provided with anti-slip teeth to increase friction and prevent slippage.

[0029] Furthermore, the two inner sides of the jaws 1 near the opening are provided with anti-slip teeth, the outer contour of which is trapezoidal, to further prevent slippage.

[0030] In some embodiments, the opening direction of the jaws 1 is perpendicular to the length direction of the handle 2, and the direction of force application during use is perpendicular to the length direction of the clamp handle 2, which facilitates the application of force.

[0031] like Figure 4 As shown, when replacing the valve before the gas meter, the open jaw 1 is clamped onto the outer octagon of the failed and leaking main valve, and the handle 2 is turned in the direction of loosening. During installation, the same method is used to turn the handle 2 in the direction of tightening, so as to achieve the effect of quickly adapting the corresponding parts without adjusting the opening size.

[0032] In summary, the application of this utility model can reduce the labor intensity of replacing the gas meter valve and reduce the amount of manual work required during the replacement process.

[0033] This invention fits well with the outer octagon of the valve in front of the instrument, avoiding the drawback of traditional tools that require adjustment of the jaw opening size, thus saving time.

[0034] This invention can adapt to the needs of different gas usage locations and can work well in various conditions such as rusted, dirty, greasy, and dusty pipes, reducing the operational risks caused by slippage and tool drop.

[0035] This utility model has a simple structure and moderate size, and can be used to replace most of the manual labor in valve replacement in various confined spaces.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
