Description

Technical Field

[0001] This application relates to the technical field of pipe wrenches, and in particular, to a pipe wrench for tightening the inner wall of a pipe. Background Art

[0002] A pipe wrench is a tool for clamping a pipe. Generally, it clamps the outer diameter of the pipe to drive the pipe to rotate for pipe installation and disassembly.

[0003] A pipe wrench generally includes a handle part and a clamping part. The clamping part is slidably connected to the handle part, and the distance between the clamping part and the handle part is adjusted by rotating an adjusting ring with internal threads installed on the handle part. The outer wall of the pipe is clamped by the tooth patterns of the clamping part and the handle part.

[0004] However, since the stress point is mainly located in the tooth pattern part during the process of clamping the outer wall of the pipe by the pipe wrench and driving the pipe to rotate, the protective layer of the outer wall of the pipe will be scratched. In some special usage scenarios, scratches or abrasions are not allowed on the outer wall of the pipe. Therefore, a pipe wrench that does not damage the outer wall of the pipe is needed to achieve pipe installation in the above scenarios. Summary of the Utility Model

[0005] The purpose proposed by the utility model of this application is to improve the problem that the existing pipe wrench will cause wear to the outer wall of the pipe during pipe installation. This application provides a new type of pipe wrench.

[0006] The new type of pipe wrench provided by this application adopts the following technical solutions:

[0007] A new type of pipe wrench includes a handle and a movable jaw. The movable jaw is in an "L" shape and is slidably connected to the side wall of the handle. The handle drives the movable jaw to slide by rotating its own adjusting ring. The movable jaw and the handle can be clamped to each other. Its characteristics are: A first clamping part is installed on the part of the handle that can be clamped to the movable jaw in a direction away from the adjusting ring of the handle, and a second clamping part opposite to the first clamping part is installed on the movable jaw;

[0008] Toothed patterns are distributed on the opposite side walls of the first clamping part and the second clamping part.

[0009] Optionally, a first rib plate is fixedly arranged on the side wall of the handle facing the second clamping part, and a second rib plate that abuts against the first rib plate is fixedly arranged on the first clamping part;

[0010] A third rib plate is fixedly arranged on the side wall of the movable jaw facing the first clamping part, and a fourth rib plate that abuts against the third rib plate is fixedly arranged on the second clamping part.

[0011] Optionally, the positions of the first rib plate and the third rib plate are staggered, and the first rib plate will not abut against the third rib plate.

[0012] Optionally, an installation groove is formed in the side wall of the handle in contact with the first clamping portion, and the installation groove is also formed in the side wall of the movable jaw in contact with the second clamping portion;

[0013] Both the first clamping portion and the second clamping portion are fixedly provided with installation blocks that can extend into the installation groove;

[0014] Both the handle and the movable jaw are provided with installation holes communicating with the installation groove;

[0015] The installation block is provided with a fixing hole facing the installation hole;

[0016] The installation hole is threadedly connected with an installation bolt, and the installation bolt can be located in both the installation hole and the fixing hole at the same time.

[0017] Optionally, when the tooth patterns of the first clamping portion and the second clamping portion face each other, the tooth pattern of the first clamping portion is flush with the first rib plate, and the tooth pattern of the second clamping portion is flush with the third rib plate.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] Through the settings of the first clamping portion and the second clamping portion, the first clamping portion and the second clamping portion can be extended into the pipeline interior, and by rotating the adjusting ring on the handle, the distance between the first clamping portion and the second clamping portion can be increased. The first clamping portion and the second clamping portion are tightened against the inner wall of the pipeline through the tooth patterns, thereby realizing installation without abrasion of the outer wall of the pipeline;

[0020] The positions of the second rib plate and the fourth rib plate can effectively improve the stress intensity of the first clamping portion and the second clamping portion, and the staggered setting of the positions can also effectively increase the range of the inner diameter of the pipeline that can be extended into;

[0021] The detachable installation setting of the first clamping portion and the second clamping portion also realizes the change of the clamping direction, so that the first clamping portion and the second clamping portion can also clamp the outer wall of the pipeline. Description of the Drawings

Detailed implementation mode

[0027] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0028] The embodiment of the present application discloses a new type of pipe wrench.

[0029] Referring to Figure 1 , the new type of pipe wrench includes a handle 1 and a movable jaw 2. The movable jaw 2 is in an "L" shape and is slidably connected to the side wall of the handle 1. The part of the movable jaw 2 slidably connected to the handle 1 has tooth patterns, and the handle 1 meshes with the tooth patterns of the movable jaw 2 through the rotation of its own adjusting ring, thereby driving the movable jaw 2 to slide, so that the movable jaw 2 and the handle 1 can clamp each other. A first clamping portion 3 is installed on the part of the handle 1 that can clamp with the movable jaw 2 in a direction away from the adjusting ring of the handle 1, and a second clamping portion 4 is installed on the movable jaw 2, and the second clamping portion 4 is opposite to the first clamping portion 3 in position. Tooth patterns are distributed on the opposite side walls of the first clamping portion 3 and the second clamping portion 4.

[0030] By rotating the adjusting ring of the handle 1, the first clamping portion 3 and the second clamping portion 4 are brought closer to each other, and then the first clamping portion 3 and the second clamping portion 4 are inserted into the pipeline together. Then rotate the adjusting ring of the handle 1 to make the first clamping portion 3 and the second clamping portion 4 move away from each other. The first clamping portion 3 and the second clamping portion 4 are pressed against the inner wall of the pipeline through the tooth patterns, and then the handle 1 is rotated to install the pipeline. Installing the pipeline in this way can effectively reduce the damage to the outer wall of the pipeline.

[0031] Referring to Figure 2 and Figure 3 , a mounting groove 12 is opened on the side wall of the handle 1 in contact with the first clamping portion 3, and the mounting groove 12 is also opened on the side wall of the movable jaw 2 in contact with the second clamping portion 4. The first clamping portion 3 and the second clamping portion 4 are both fixedly provided with mounting blocks 32 that can extend into the mounting groove 12. The mounting blocks 32 are cuboids and fit with the inner wall of the mounting groove 12. The handle 1 and the movable jaw 2 are both provided with mounting holes 13 communicating with the mounting groove 12, and the mounting blocks 32 are provided with fixing holes 321 facing the mounting holes 13. A mounting bolt 5 is threadedly connected to the mounting hole 13, and the mounting bolt 5 can be located in both the mounting hole 13 and the fixing hole 321 at the same time.

[0032] A first rib plate 11 is fixedly provided on the side wall of the handle 1 facing the second clamping part 4, and a second rib plate 31 that abuts against the first rib plate 11 is fixedly provided on the first clamping part 3. A third rib plate 21 is fixedly provided on the side wall of the movable jaw 2 facing the first clamping part 3, and a fourth rib plate 41 that abuts against the third rib plate 21 is fixedly provided on the second clamping part 4. The positions of the first rib plate 11 and the third rib plate 21 are staggered, and the first rib plate 11 will not abut against the third rib plate 21.

[0033] Reference Figure 4 , when the tooth patterns of the first clamping part 3 and the second clamping part 4 face each other, the tooth pattern of the first clamping part 3 is flush with the first rib plate 11, and the tooth pattern of the second clamping part 4 is flush with the third rib plate 21.

[0034] The first rib plate 11 and the second rib plate 31 abut against each other, and the third rib plate 21 and the fourth rib plate 41 are butt-jointed, which can provide structural support when the first clamping part 3 and the second clamping part 4 tighten against the inner wall of the pipeline, thereby improving the structural strength of the first clamping part 3 and the second clamping part 4. At the same time, the staggered arrangement of the first rib plate 11 and the third rib plate 21 enables the first clamping part 3 and the second clamping part 4 to be closer to each other, expanding the range of the inner diameter of the pipeline that can be installed. The detachable setting of the first clamping part 3 and the second clamping part 4 realized by the mounting bolts 5 can also change the orientation of the tooth patterns of the first clamping part 3 and the second clamping part 4, and can clamp the outer wall of the pipeline through the first clamping part 3 and the second clamping part 4, improving the functionality of the pipe wrench.

[0035] The implementation principle of a new type of pipe wrench in the embodiment of the present application is as follows: By rotating the adjusting ring of the handle 1, the position of the interactive jaw is adjusted, so that the first clamping part 3 and the second clamping part 4 approach each other, and the first clamping part 3 and the second clamping part 4 are inserted into the pipeline. Subsequently, the first clamping part 3 and the second clamping part 4 are separated from each other, and the tooth patterns of the first clamping part 3 and the second clamping part 4 are tightened against the inner wall of the pipeline. Then, the handle 1 is rotated to drive the pipeline to rotate, thereby realizing the installation and disassembly of the pipeline. Since there is no contact with the outer wall of the pipeline, the quality of the outer wall of the pipeline after installation is improved.

[0036] The embodiments of the specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
