Description

Technical Field

[0001] This utility model relates to the field of tool technology, and in particular to a pipe wire remover. Background Technology

[0002] Pipe fitting thread breakage refers to the breakage of the threaded portion of a pipe fitting used for connection. A broken thread compromises the seal at the pipe connection, leading to leaks of fluids (such as water, gas, or oil) in the pipeline. This not only wastes resources but can also affect the normal operation of the pipeline system and even cause safety accidents. If a pipe fitting has a broken thread, replacing or repairing it increases the difficulty and complexity of the operation. The broken thread may become stuck inside the pipe or other connected fittings, making it difficult to remove and causing significant problems for maintenance work.

[0003] Currently, the main way to deal with broken pipe fittings is to chisel or cut the fitting, which can easily damage the fitting or joint. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe wire remover, which addresses the problem that existing pipe wire breakage is mainly caused by chiseling or cutting the pipe, which can easily damage the pipe or joint.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pipe wire breakage extractor, comprising:

[0007] The rod has an bulging head at one end;

[0009] The pipe fitting broken wire extractor of this utility model utilizes the principle of expansion and the principle of friction to remove the pipe fitting broken wire. The rod moves axially within the sleeve, causing the expanding head to compress and deform the deformable part. The outer edge of the deformable part can then be clamped at the broken wire location. By lifting the sleeve, the broken wire pipe fitting is removed through the friction between the deformable part and the broken wire location. This application utilizes the principles of expansion and friction, avoiding the damage caused by chiseling or cutting the broken wire pipe fitting. The extractor has a simple structure, is easy to use, and has good performance.

[0010] As a preferred technical solution of this utility model, the deformable part includes a plurality of slits arranged along the axial direction of the sleeve, the slits dividing the end of the sleeve into a plurality of tube segments, and after the bulging head is embedded in the deformable part, the tube segments spread radially along the sleeve.

[0011] As a preferred technical solution of this utility model, the outer surface of the deformable part is provided with a plurality of protrusions.

[0012] As a further preferred technical solution of this utility model, the protrusion is an external thread.

[0013] As a preferred technical solution of this utility model, the rod is an externally threaded rod, the sleeve is an internally threaded sleeve, and the rod and the sleeve are threadedly connected.

[0014] As a further preferred technical solution of this utility model, the rod is provided with a pin hole at the other end relative to the bulging head, and a pin is inserted into the pin hole.

[0015] As a preferred technical solution of this utility model, the pipe broken wire extractor further includes a driving component, which connects the rod and the sleeve, and is used to drive the rod to move axially relative to the sleeve.

[0016] As a further preferred technical solution of this utility model, the driving component adopts a portable pull rod puller or a magnetic puller.

[0017] As a preferred technical solution of this utility model, the sleeve is externally connected to a handle.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] This utility model discloses a pipe fitting broken wire extractor. The rod moves axially within the sleeve, causing the expanding head to compress and deform the deformable portion. The outer edge of the deformable portion clamps onto the broken wire location of the pipe fitting. Then, by lifting the sleeve, the broken wire is extracted through the friction between the deformable portion and the broken wire location. This application utilizes the principles of expansion and friction, avoiding damage caused by chiseling or cutting the broken wire. The extractor has a simple structure, is easy to use, and provides good results. Attached Figure Description

However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0024] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0029] In related technologies, pipe fitting thread breakage refers to the breakage of the threaded portion used for connection on a pipe fitting. Thread breakage compromises the seal at the pipe fitting connection, leading to leakage of fluids (such as water, gas, oil, etc.) in the pipeline. This not only wastes resources but may also affect the normal operation of the pipeline system and even cause safety accidents. If a pipe fitting has a broken thread, replacing or repairing it increases the difficulty and complexity of the operation. The broken thread may become stuck inside the pipe or other connected fittings, making it difficult to remove and causing significant trouble for maintenance work. Currently, the main method for dealing with broken pipe fitting threads is to chisel or cut the fitting, which easily damages the fitting or joint. Therefore, the technical solution of this application was developed, which is described below in conjunction with… Figures 1 to 2 To elaborate.

[0030] Example 1

[0031] like Figure 1 and Figure 2 As shown, the pipe wire breakage extractor of this utility model includes a rod 1 and a sleeve 2.

[0032] One end of the rod 1 is provided with an expansion head 11; one end of the sleeve 2 is provided with a deformation part 21. The rod 1 is inserted into the sleeve 2 and can move axially relative to the sleeve 2. The expansion head 11 and the deformation part 21 are located at the same end. The expansion head 11 can be embedded in the deformation part 21 to expand the deformation part 21.

[0033] In one optional embodiment, the rod 1 is an externally threaded rod, and the sleeve 2 is an internally threaded sleeve. The rod 1 and the sleeve 2 are threadedly connected, and the rod 1 can be moved axially along the sleeve 2 by turning the rod 1. A pin hole is provided at the other end of the rod 1 opposite to the bulging head 11, and a pin 3 passes through the pin hole. Specifically, the pin hole radially penetrates the end of the rod 1, and the pin 3 passes through the end of the rod 1.

[0034] In an optional embodiment, the deformable portion 21 includes a plurality of slits 211 arranged axially along the sleeve 2, the slits 211 dividing the end of the sleeve 2 into a plurality of tube segments. After the bulging head 11 is inserted into the deformable portion 21, the tube segments spread radially along the sleeve 2. The outer surface of the deformable portion 21 is provided with a plurality of protrusions 212, which can increase the friction between the deformable portion 21 and the mating fitting. Specifically, the protrusions 212 can be external threads.

[0035] The sleeve 2 is externally connected to a handle 4. The handle 4 can be welded to the sleeve 2 or detachably connected to the sleeve 2 via a clamp or other structure.

[0036] During use, do not first install the pin 3 to the rod 1. First, screw one end of the rod 1 with the pin hole into the sleeve 2. After the end of the rod 1 passes through the sleeve 2, then pass the pin 3 through the pin hole (e.g., ...). Figure 1 (as shown); then the deformed part 21 of the sleeve 2 is placed at the broken wire of the pipe fitting, and the rod 1 is continued to be turned through the pin 3, the bulging head 11 is embedded in the deformed part 21, thereby expanding the deformed part 21 (as shown). Figure 2 As shown, the outer edge of the deformable part 21 abuts against and clamps at the broken wire of the pipe fitting, completing the fastening between the sleeve 2 and the pipe fitting with the broken wire; by lifting the sleeve 2 through the handle 4, the pipe fitting is pulled out by the friction between the deformable part 21 and the broken wire of the pipe fitting; by twisting the rod 1 in the opposite direction through the pin 3, the bulging head 11 disengages from the deformable part 21, the deformable part 21 retracts, releasing the fastening between the sleeve 2 and the pipe fitting, and the pipe fitting is removed intact without chiseling or cutting.

[0037] This embodiment describes a pipe wire breakage extractor. The rod 1 moves axially within the sleeve 2, causing the expanding head 11 to compress and deform the deformable portion 21. The outer edge of the deformable portion 21 can clamp onto the broken wire location of the pipe. Then, the sleeve 2 is lifted, and the broken pipe is removed through the friction between the deformable portion 21 and the broken wire location. This application utilizes the principles of expansion and friction, avoiding damage caused by chiseling or cutting the broken pipe. The extractor has a simple structure, is easy to use, and has good performance.

[0038] Example 2

[0039] Not shown, the pipe wire breakage extractor of this utility model differs from Embodiment 1 in that this embodiment also includes a driving component, the rod 1 has a smooth outer wall and the sleeve 2 has a smooth inner wall.

[0040] The driving component connects the rod 1 and the sleeve 2, and the driving component is used to drive the rod 1 to move axially relative to the sleeve 2.

[0041] In some alternative embodiments, the driving component is a portable lever puller or a magnetic puller. The portable lever puller is generally designed using a lever or hydraulic principle, featuring a handle and a pulling head that engages with the sleeve 2 and the rod 1. By operating the handle, a strong pulling force is generated using leverage or hydraulic pressure to pull the rod 1 within the sleeve 2. The magnetic puller utilizes the principle of magnetic attraction, with a small magnetic chuck connected to the handle. The magnetic chuck is attracted to the end of the rod 1, and by applying a pulling force through the handle, the rod 1 is pulled from the sleeve 2 using magnetic force.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
