Description

Technical Field

[0001] This utility model relates to the field of indoor gas meter repair technology, and in particular to an auxiliary tool for repairing the elbow of the branch pipe in front of an indoor gas meter. Background Technology

[0002] In existing technologies, the tools commonly used by gas industry workers when replacing or repairing branch pipes before the indoor meter are mainly pipe wrenches and spanners.

[0003] In real-world scenarios, when a gas meter branch pipe malfunctions, traditional repair tools may not be able to perform quick repairs due to the limitations of the on-site working environment (obstructions from cabinets, tiles, etc. in the user's renovation). The main reason is that traditional repair tools are difficult to quickly engage with the branch pipe before the meter and require repeated adjustments. Even if they can engage properly, there is often not enough space to apply force to rotate the tool.

[0004] Because the existing pipe wrench has a relatively thick blade, the blade has a large rotation radius when rotating. Even a slight rotation may be blocked by obstacles such as tiles or cabinets, which greatly reduces the efficiency of maintenance.

[0005] In another case, even if the pipe fittings of the branch pipe elbows in front of the meter do not need to be removed with pipe wrenches, but only need to be clamped on the outer edge of the branch pipe elbows in front of the meter for support, the existing wrenches are too thick and cannot be clamped into the branch pipe elbows in front of the meter.

[0006] The external contour dimensions of the branch pipe elbow before the meter are naturally larger than the corresponding external threaded pipe fitting, which often makes it impossible for tools to fit into the branch pipe elbow before the meter where the clearance between the elbow and the wall and external decoration is insufficient.

[0007] If further clearing operations are carried out, on the one hand, users' willingness will be constrained. Some users will often reduce their enthusiasm for cooperation when they hear that it is necessary to damage part of the decoration, especially when it involves rental properties. On the other hand, clearing operations will also prolong the maintenance cycle and operation time, reduce efficiency, and fail to protect the lives and property of the people in a timely manner.

[0008] The aforementioned deficiencies in existing tools make it impossible to carry out repair and replacement work for faulty branch pipes before the meter without damaging the user's existing decoration. It often requires time to communicate with the user to remove obstacles and other related matters, resulting in the inability to eliminate potential hazards in a timely manner.

[0009] Therefore, how to improve and upgrade existing tools used for repairing indoor gas meter branch pipes so that they can adapt to complex conditions such as close distance between the pipe wall and obstacles and small rotation angle, and can quickly adapt to the outer diameter of different diameters of the branch pipe bends without adjusting the opening, reduce the probability of slippage, and achieve the repair of the branch pipes before the meter without clearing obstacles has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0010] In view of the above-mentioned deficiencies of the prior art, this utility model provides an auxiliary tool for repairing branch pipe elbows before indoor gas meters. The purpose is to not only quickly clamp the branch pipe elbow without adjusting the opening of the pipe wrench, but also to rotate the tool under conditions where the clearance between the pipe wall and the obstacle is insufficient, thus fixing and rotating the elbow. At the same time, by changing the opening part, the opening tool can be adapted to the outer contour size of common elbows, providing practitioners with a new repair method and reducing the probability of needing to remove obstacles.

[0011] To achieve the above objectives, this utility model discloses an auxiliary tool for repairing the elbow of the branch pipe in front of an indoor gas meter, including one or more pliers and handles.

[0012] Each of the pliers heads is detachably connected to one end of the handle, and each includes a connecting part for connecting to the handle, and a C-shaped open ring disposed on the side of the connecting part facing away from the handle for locking the bend of the gas meter front branch pipe.

[0013] Each of the C-shaped open rings has a smooth arc-shaped outer surface, and the inward-facing side has several inward protrusions around the axis, forming an interlocking pattern through the several protrusions;

[0014] The opening width of each of the C-shaped open rings is greater than the outer diameter of the gas meter front branch pipe elbow of different sizes, and the inner diameter satisfies the following: when the axis forms an angle of 30° to 45° with the clamping part of the corresponding gas meter front branch pipe elbow, the protrusions of the corresponding interlocking pattern can clamp the corresponding gas meter front branch pipe elbow by friction.

[0015] Preferably, each of the pliers head and the handle is connected by a tenon joint, and bolts and corresponding nuts are provided to form a detachable connection;

[0016] The connecting portion of each of the aforementioned clamp heads has a groove structure;

[0017] Each of the groove structures is in a transition fit with one end of the handle that connects to any of the pliers heads;

[0018] Each of the groove structures is secured by bolts and corresponding nuts that penetrate both side walls after being inserted into the handle.

[0019] Preferably, the surfaces with the largest area on both sides of the handle are provided with weight-reducing grooves.

[0020] Preferably, the handle length is 300mm.

[0021] Preferably, each of the pliers heads is made of CRV chrome vanadium steel.

[0022] The beneficial effects of this utility model are:

[0023] The application of this utility model can quickly eliminate safety hazards in the maintenance of branch pipes before indoor gas meters, ensure the gas safety of customers, reduce the risk of slippage and detachment, improve work efficiency, and is more friendly to the non-dominant hand of the operator.

[0024] This invention can be well and efficiently matched with and clamped by elbows of various diameters. By replacing the pliers head with one of the corresponding size to the elbow, the drawback of traditional tools that require frequent adjustment of the jaw opening size is avoided, thus saving time.

[0025] This invention can reduce the need for operators to use their non-dominant hand for fine operations.

[0026] This invention can adapt to situations where the clearance between pipes and obstacles is insufficient in confined spaces, and reduces the probability of interference with obstacles when force is applied to rotate the pipe wrench.

[0027] 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. Attached Figure Description

[0036] Example: Figures 1 to 8 As shown, the auxiliary tool for repairing the elbow of the branch pipe in front of the indoor gas meter includes one or more pliers 1 and handles 2.

[0037] Each pliers head 1 has a smooth arc-shaped outer surface and is detachably connected to one end of the handle 2. Each pliers head 1 includes a connecting part 12 for connecting to the handle 2, and a C-shaped open ring 11 on the side of the connecting part 12 facing away from the handle 2 for locking the bend of the gas meter front branch pipe.

[0038] Each C-shaped open ring 11 has a smooth arc-shaped outer surface, and the inward-facing side has several inward protrusions around the axis, forming interlocking patterns through the protrusions.

[0039] The opening width of each C-shaped open ring 11 is greater than the outer diameter of the gas meter front branch pipe elbow of different sizes. The inner diameter satisfies the following: when the axis forms an angle of 30° to 45° with the clamping part of the corresponding gas meter front branch pipe elbow, several protrusions of the corresponding interlocking pattern can clamp the corresponding gas meter front branch pipe elbow through friction.

[0040] The pliers head 1 of this utility model abandons the drawbacks of traditional pipe wrenches having a large size and large rotation radius. It adopts a circular design, and the outer surface of each C-shaped opening ring 11 is a smooth arc shape, which can better adapt to the situation where the net distance between the pipe and the wall is limited.

[0041] In practical applications, the detachable clamp head 1 can be matched with various pipe diameters of gas meter front branch pipe elbows, such as... Figure 6 As shown, clamp head 13 corresponds to a DN20 pipe diameter elbow, clamp head 14 corresponds to a DN25 pipe diameter elbow, and clamp head 15 corresponds to a DN32 pipe diameter elbow.

[0042] In some embodiments, each pliers head 1 and handle 2 are connected by a tenon joint, and a bolt 21 and a corresponding nut are provided to form a detachable connection;

[0043] The connecting part 12 of each clamp head 1 has a groove structure;

[0044] Each groove structure is in a transition fit with one end of the handle 2 that connects to any of the pliers heads 1;

[0045] Each groove structure is fitted with bolts 21 that penetrate both side walls and corresponding nuts to achieve fastening after being inserted into the handle 2.

[0046] In practical applications, this utility model is connected to the handle 2 in a detachable manner via bolts 20 and nuts. By removing bolts 20 and nuts, different corresponding pliers heads 1 can be replaced, and by tightening bolts 20 and nuts, it can be used normally.

[0047] In some embodiments, the largest surfaces on both sides of the handle 2 are provided with weight-reducing grooves 22.

[0048] In some embodiments, the handle 2 is 300 mm long.

[0049] In some embodiments, each clamp head 1 is made of CRV chrome vanadium steel.

[0050] In practical use, such as Figure 8 As shown, when a leak is found in a certain set of pipe fittings in front of the indoor gas meter branch pipe or valve, maintenance work is required. After applying this utility model, the operator can use one hand to fix the corresponding gas meter branch pipe elbow to prevent it from rotating, while the operator uses the other hand to operate pipe wrenches, wrenches and other corresponding tools to repair the corresponding pipe fittings, valves, etc.

[0051] Especially when the external threaded pipe fitting is too short or is blocked by obstacles, making it impossible for conventional tools to properly clamp it, this utility model can clamp the exposed elbow for fixing operations, avoiding demolition and other obstacle clearing operations, and reducing construction costs and difficulties.

[0052] Through the aforementioned technical means, the application of this utility model can replace traditional tools without requiring adjustment of the opening size. Whether disassembling or tightening pipe fittings, this utility model can adapt to corresponding pulling or pushing forces, fixing pipe fittings that do not require maintenance and preventing rotation of the branch pipe elbow before the gas meter.

[0053] 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.
