Description

Technical Field

[0001] The utility model relates to the technical field of gas repair tools, in particular to a gas repair tool. Background Art

[0002] As the length of gas pipelines continues to grow, gas companies' safety inspections have become increasingly critical. To ensure the smooth and safe operation of gas pipelines, companies need to regularly dispatch professional inspection teams for on-site visits and inspections. However, this task is fraught with challenges. Because gas pipeline systems incorporate a wide variety of pipes and connectors, inspectors must carry a variety of tools, such as pipe wrenches and needle-nose pliers, during routine inspections to handle a variety of possible repairs and inspections.

[0003] However, the reality is that each home inspection requires inspectors to spend a considerable amount of time and effort selecting the right tools from a heavy tool kit, which is cumbersome to store and easily lost. This not only significantly increases the inspection workload but also results in unnecessary waste of time and human resources. Therefore, optimizing this workflow, reducing unnecessary costs, and improving inspection efficiency have become major challenges for gas companies. Utility Model Content

[0020] The following is further described in detail through specific implementation methods:

[0021] Example 1

[0022] like Figure 1-4 As shown, this embodiment shows a gas inspection tool, including a needle-nose pliers part 1; the needle-nose pliers part 1 includes a clamping part 11, a first U-shaped handle 12 and a second U-shaped handle 13 respectively hinged to the clamping part 11, and the hinged connection facilitates the folding and storage of the handles; the clamping part 11 includes a group of hinged clamping nozzles.

[0023] One end of the first U-shaped handle 12 is hinged to the clamping portion 11, and the other end is hinged to a flashlight 2; the flashlight 2 can be completely hidden in the U-shaped handle after being folded through the hinged connection; the flashlight 2 is used to meet the needs of working environments with insufficient light, and at the same time, the flashlight 2 can be folded and stored inside the first U-shaped handle 12 when walking. One end of the second U-shaped handle 13 is hinged to the clamping portion 11, and the other end is fixed with a pipe clamp portion 3;

[0024] The pipe wrench portion 3 includes a curved pipe wrench body 31, one end of which is fixedly connected to the second U-shaped handle 13; a movable jaw 32 that is linearly slidably connected to the curved pipe wrench body 31; a fixed jaw 34 that is fixedly connected to the curved pipe wrench body 31 via a pin 33; and an adjustment nut 35 for adjusting the linear displacement of the movable jaw 32. The opening between the movable jaw 32 and the fixed jaw 34 is used to clamp the pipe. The movable jaw 32 is used to adjust the opening size to accommodate different gas pipes and connectors. The movable jaw 32 includes a screw portion 321 that matches the adjustment nut 35. During operation, the adjustment nut 35 is rotated, and the threaded connection between the adjustment nut 35 and the screw portion 321 enables the movable jaw 32 to move linearly relative to the curved pipe wrench body 31. The linear movement direction of the movable jaw 32 is not parallel to the length of the second U-shaped handle 13, which facilitates the application of force by the handle. Specifically, the needle-nose pliers 1 and the pipe wrench are two tools that are frequently used during gas maintenance. They need to be used extensively to clamp and rotate gas pipes and interfaces. If you frequently search for replacements in the tool kit during use, it will be laborious and time-consuming, and it will also be extremely inconvenient to store them and they are easy to lose. Therefore, they are designed as foldable integrated tools, which can greatly improve work efficiency, improve storage and portability, and prevent tool loss.

[0025] Further explanation, in further implementation of this embodiment, as Figure 3-4 As shown, the clamping portion 11 includes an arc-shaped hinge seat 111 and a limiting step 112 fixedly arranged below the hinge seat 111; both the first U-shaped handle 12 and the second U-shaped handle 13 are provided with a U-shaped limiting block 131 that can contact and abut the limiting step 112 and a folding groove 132 that matches the arc-shaped hinge seat 111; in actual operation, when the first U-shaped handle 12 and the second U-shaped handle 13 move toward each other, the limiting step 112 abuts against the U-shaped limiting block 131 to achieve the clamping action of the clamping portion 11; conversely, when the first U-shaped handle 12 and the second U-shaped handle 13 move away from each other, the arc-shaped hinge seat 111 is hingedly connected to achieve the folding of the clamping portion 11 into the folding groove 132. The foldable, accumulative and deployable needle-nose pliers 1 is portable, has a reliable structure, is easy to accumulate, is easy to carry, is not easy to lose, and has strong practicality.

[0026] Example 2

[0027] like Figure 1-4As shown, another embodiment shows a gas repair tool, including a needle-nose pliers portion 1; the needle-nose pliers portion 1 includes a clamp portion 11, a first U-shaped handle 12 and a second U-shaped handle 13 respectively hinged to the clamp portion 11; one end of the first U-shaped handle 12 is hinged to the clamp portion 11, and the other end is hinged to a flashlight 2; the flashlight 2 can be completely hidden in the U-shaped handle after being folded through the hinge connection; one end of the second U-shaped handle 13 is hinged to the clamp portion 11, and the other end is fixed with a pipe wrench portion 3;

[0028] The pipe clamp portion 3 includes an arc-shaped pipe clamp body 31 fixedly connected to the second U-shaped handle 13 at one end, a movable jaw 32 linearly slidably connected to the arc-shaped pipe clamp body 31, a fixed jaw 34 fixedly connected to the arc-shaped pipe clamp body 31 via a pin 33, and an adjusting nut 35 for adjusting the linear displacement of the movable jaw 32; the movable jaw 32 includes a screw portion 321 matching the adjusting nut 35. During actual operation, the adjusting nut 35 is rotated, and the threaded connection between the adjusting nut 35 and the screw portion 321 enables the movable jaw 32 to move linearly relative to the arc-shaped pipe clamp body 31, wherein the linear movement direction of the movable jaw 32 is not parallel to the length direction of the second U-shaped handle 13.

[0029] Further explanation, in further implementation of this embodiment, as Figure 3 As shown, the flashlight 2 includes a cylindrical lamp body 21; one end of the lamp body 21 is threadedly connected to a detachable LED lamp head 22, which is convenient for later maintenance and replacement of the lamp head, and the other end is hinged to the first U-shaped handle 12 through a hinge rod 23, which facilitates the flashlight 2 to be folded and stored inside the first U-shaped handle 12.

[0030] Furthermore, in these embodiments, the flashlight 2 is powered by a built-in dry cell battery, which is easy to replace. Of course, commonly used cylindrical batteries on the market, such as lithium batteries, can also be used.

[0031] Furthermore, in some other embodiments, the lamp body 21 includes an aluminum alloy shell, which has good protection and is lightweight; the outer wall of the aluminum alloy shell is covered with an anodized layer, which has good rust prevention effect and beautiful appearance.

[0032] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
