Description

Technical Field

[0001] This utility model relates to the field of maintenance tool technology, specifically a tool for removing broken wires. Background Technology

[0002] During pipeline inspection and maintenance, it is common to encounter situations where pipe ends break off inside the pipeline. These broken ends (broken wires) are usually difficult to remove, posing significant challenges to maintenance work. While some tools exist for removing broken wires, most of these tools have limitations.

[0003] For example, Chinese utility model patent application No. 202421665299.8 discloses a faucet and angle valve broken wire extractor. This tool, by setting two specifications of locking parts, can adapt to broken wires of different sizes, and achieves tight contact between the locking parts and the inner surface of the broken wire through a spacing drive component, thereby successfully removing the broken wire. However, in actual use, this tool cannot rotate the balance bolt and the adjusting bolt simultaneously, causing the two extractor bodies to be unable to effectively approach or move away, and failing to effectively lock and fix the wire end when clamping and fixing it. In addition, during actual use, due to the limited contact area between the locking parts and the broken wire, this tool may not provide sufficient friction for some larger broken wires, resulting in a low success rate of extraction. Furthermore, this tool is limited to removing cylindrical wire ends and is not suitable for removing tubular wire ends.

[0004] Therefore, there is an urgent need in the existing technology for a tool that is simple in structure, has high material utilization, is easy to produce and process, and can effectively improve the success rate of broken wire removal. Utility Model Content

The removal component includes two parallel wire-clamping rods, each consisting of a rod body and a taper. The taper is axially shaped as a semi-conical structure, and both the curved outer wall and the planar outer wall of the taper are engraved with progressively or spirally arranged raised patterns. After the drive component and the removal component are installed together, the drive component is connected to the two wire-clamping rods in the removal component, and the drive component drives the two wire-clamping rods to move synchronously towards each other or away from each other.

The adjusting bolts are threadedly connected to the locking rods. The adjusting bolts are divided by the middle of the two locking rods, and the external threads at both ends of the adjusting bolts are either positive or negative. After the two adjusting bolts rotate synchronously, they drive the two locking rods to move towards each other or away from each other synchronously.

[0012] Optionally, the driving component is connected to two adjusting bolts respectively, and the driving component drives the two adjusting bolts to rotate synchronously.

[0013] Optionally, the driving component includes a mounting housing, a drive gear, and a rocker arm. The drive gear is rotatably mounted inside the mounting housing.

The ends of the two adjusting bolts are detachably inserted into the mounting housing. The drive gear is connected to the two adjusting bolts in a transmission manner, and the drive gear drives the two adjusting bolts to rotate synchronously.

[0017] Optionally, threads are engraved on both the curved outer wall and the planar outer wall of the tap portion.

[0018] (III) Beneficial Effects

[0019] This utility model provides a tool for removing broken wires, which has the following beneficial effects:

[0020] 1. This utility model's broken wire removal tool features two parallel wire-clamping rods. The special structure of their taper sections allows for a larger contact area with the inner surface of the broken wire. In particular, the gradually or spirally arranged raised textures significantly increase friction, thereby applying force more effectively to the broken wire, preventing slippage, and improving the success rate of wire removal. Furthermore, a drive mechanism moves the two wire-clamping rods synchronously towards or away from each other, allowing for flexible adjustment of the rod positions according to the size and condition of the broken wire. This further ensures tight contact between the rods and the broken wire, resulting in better force application and smooth wire removal. It is suitable for removing broken wires of various sizes, making it widely applicable.

[0021] 2. The broken wire removal tool of this utility model can effectively remove the wire column or wire tube by simultaneously moving the two wire clamping rods closer together or further apart. When the two wire clamping rods are close together, the taper parts of the two wire clamping rods can clamp and fix the wire column (such as the broken bolt thread) by clamping. When the two wire clamping rods are far apart, the taper parts of the two wire clamping rods can expand outward so that the conical curved surface of the taper part can tightly abut against the inner wall of the wire tube. The two are in a locked state, thereby achieving effective fixation of the wire tube, thus better applying force to the broken wire, effectively preventing slippage, and improving the success rate of broken wire removal.

[0022] 3. The broken wire removal tool of this utility model has a simple structural design. Compared with the existing technology that requires multiple holes to be made in the body of the extractor, this utility model only needs to set two parallel wire-locking rods and corresponding driving components, which greatly reduces the amount of material used and lowers the production cost. At the same time, the manufacturing process of this structure is simpler, the production efficiency is higher, and it is easy to mass-produce and promote its application. Attached Figure Description

[0033] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying anything.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0035] Example 1, please refer to Figures 1 to 6 This utility model provides a technical solution: This technical solution is applicable to the removal of broken threads (referring to threaded tubes with threaded outer walls, such as broken faucet threaded heads; or threaded columns with threaded outer walls, such as bolts) inside pipe 5 (or other carriers used for threaded installation of threaded ends). The broken thread is also known as the broken wire 4.

[0036] A tool for removing broken wires includes a power rod 3, a drive component 2, and a removal component 1. The drive component 2 and the removal component 1 are detachably installed together, and the power rod 3 and the removal component 1 are detachably installed or fixedly installed together.

[0037] The removal component 1 includes two parallel-arranged wire-locking rods 11. Each wire-locking rod 11 consists of a rod body 111 and a tap portion 112. The tap portion 112 is a semi-conical structure cut along the axial direction, and both the curved outer wall and the flat outer wall of the tap portion 112 are engraved with progressively arranged or spirally arranged raised patterns. The wire-locking rods 11 are made of metal or alloy materials, which are relatively hard. This structural design further increases the friction between the tap portion 112 and the inner surface of the broken wire, improving the success rate of wire removal.

[0038] After the drive component 2 is installed in conjunction with the removal component 1, the drive component 2 is connected to the two locking screws 11 in the removal component 1. The drive component 2 drives the two locking screws 11 to move closer to each other or move away from each other synchronously.

[0039] The drive component 2 adjusts the distance between the two clamping rods 11 to accommodate broken wires 4 of different sizes. The removal component 1 directly contacts the broken wire 4 and applies force to remove it. The special design of the clamping rods 11 allows for a larger contact area with the broken wire 4, increasing friction and preventing slippage. The tap portion 112 of the clamping rod 11 is designed as a semi-conical structure, with gradually arranged or spirally arranged raised patterns on its outer wall significantly increasing friction with the broken wire 4. The rotation of the adjusting bolt 12 drives the clamping rods 11 closer to or further away, adjusting the contact tightness between the clamping rods 11 and the broken wire 4. Once the clamping rods 11 are in close contact with the broken wire 4, the power rod 3 applies force, causing the clamping rods 11 to rotate, thereby removing the broken wire 4 from the pipe 5. By adjusting the rotation of the adjusting bolt 12, the distance between the two clamping rods 11 can be precisely controlled, ensuring tight contact between the clamping rods 11 and the broken wire 4.

[0040] Specifically, the power rod 3 is fixedly or detachably installed with the rod body portion 111 of at least one locking rod 11. The power rod 3 extends laterally through the rod body portion 111 of at least one locking rod 11 and the two are inserted into each other.

[0041] This structural design allows the power rod 3 to effectively transmit power to the clamping rod 11, causing the clamping rod 11 to rotate and thus removing the broken wire. The power rod 3 provides power for removing the broken wire, driving the clamping rod 11 to rotate. Through the rotation of the power rod 3, the broken wire 4 can be effectively removed from the pipe 5. The power rod 3 is fixedly or detachably connected to the rod body 111 of the clamping rod 11, ensuring effective power transmission through a plug-in connection; at the same time, it facilitates practical operation.

[0042] Specifically, the disassembly component 1 also includes two adjusting bolts 12, which are arranged in parallel and extend laterally through the two locking rods 11. The adjusting bolts 12 are threadedly connected to the locking rods 11. The adjusting bolts 12 have opposite threads on their outer ends, with the middle of the two locking rods as the boundary. When the two adjusting bolts 12 rotate synchronously, they drive the two locking rods 11 to move towards each other or away from each other synchronously.

[0043] This structural design allows for precise control of the distance between the two wire clamping rods 11 by adjusting the rotation of the bolt 12, thereby enabling the adaptation and clamping of broken wires of different sizes.

[0044] More specifically, the drive component 2 is connected to the two adjusting bolts 12 respectively, and the drive component 2 drives the two adjusting bolts 12 to rotate synchronously.

[0045] More specifically, the drive component 2 includes a mounting housing, a drive gear 24, and a rocker handle 23. The drive gear 24 is rotatably mounted inside the mounting housing, and one end of the rocker handle 23 penetrates through the mounting housing, with the penetrating end of the rocker handle 23 coaxially fixedly mounted with the drive gear 24. The ends of the two adjusting bolts 12 are detachably inserted into the mounting housing, and the drive gear 24 is connected to the two adjusting bolts 12 in a transmission manner, driving the two adjusting bolts 12 to rotate synchronously.

[0046] This structural design allows the rotation of the crank handle 23 to easily drive the drive gear 24 to rotate, thereby causing the two adjusting bolts 12 to rotate synchronously and adjust the spacing of the locking screw 11.

[0047] More specifically, the ends of the two adjusting bolts 12 are fixedly connected with driven gears 13, which penetrate one side wall of the mounting housing. After the driven gears 13 penetrate and are inserted into the interior of the mounting housing, they mesh with the driving gears 24.

[0048] This structural design allows the driving gear 24 to drive the two driven gears 13 to rotate synchronously through meshing, thereby achieving synchronous driving of the two adjusting bolts 12. The driving component 2 drives the adjusting bolts 12 to rotate synchronously through the meshing of the driving gear 24 and the driven gears 13, thereby adjusting the spacing of the locking screw 11.

[0049] More specifically, the mounting housing includes a first channel steel 21, a second channel steel 25, and multiple fixing bolts 22. The first channel steel 21 is fixedly installed to the second channel steel 25 by the multiple fixing bolts 22. After the first channel steel 21 and the second channel steel 25 are fixedly installed, they form an internal mounting cavity for installing the drive gear 24 and the driven gear 13.

[0050] This structural design provides the mounting housing with excellent stability and strength, effectively supporting and protecting internal transmission components such as gears. The first channel steel 21 and the second channel steel 25 are easily disassembled for convenient maintenance.

[0051] Specifically, threads are engraved on both the curved outer wall and the flat outer wall of the tap portion 112.

[0052] This structural design further increases the friction between the tap 112 and the inner surface of the broken wire 4, thereby improving the success rate of removing the broken wire 4.

[0053] In actual implementation, the thread direction of the two adjusting bolts 12 in this technical solution needs to be matched with the rotation direction of the two driven gears 13. That is, when the two adjusting bolts 12 rotate synchronously, they can only drive the two locking rods 11 to move closer or further away synchronously.

[0054] In use, first insert the retaining rod 11 of the removal component 1 into the broken wire 4 inside the pipe 5. By rotating the crank 23 of the drive component 2, the driving gear 24 is driven to rotate, thereby driving the two driven gears 13 to rotate synchronously, which in turn causes the two adjusting bolts 12 to rotate synchronously. The rotation of the adjusting bolts 12 will drive the two retaining rods 11 to move closer or further away from each other synchronously, thereby adjusting the contact tightness between the retaining rods 11 and the broken wire 4. When the retaining rods 11 are in tight contact with the broken wire 4, the force is applied by the power rod 3 to drive the retaining rods 11 to rotate, thereby smoothly removing the broken wire 4 from the pipe 5.

[0055] Example 2, please refer to Figures 1 to 6 This second embodiment is a replacement implementation of certain technical means in the first embodiment. The main difference between this embodiment and the first embodiment is that two driven gears 13 are rotatably mounted inside the mounting housing, and the driving gear 24 meshes with the two driven gears 13 respectively. A rectangular slot is provided at the axis of the driven gear 13, and two through holes are provided on one side wall of the mounting housing, with the through holes corresponding to the rectangular slots. The end of the adjusting bolt 12 has a rectangular structure. After the adjusting bolt 12 passes through the through hole on the mounting housing, the rectangular structure of the end of the adjusting bolt 12 is inserted into the rectangular slot of the driven gear 13, and the rectangular structure of the end of the adjusting bolt 12 engages with the driven gear 13.

[0056] This structural design makes the connection between the adjusting bolt 12 and the driven gear 13 more stable and the transmission more reliable. It avoids repeated disassembly of the driven gear 13 and prevents meshing errors between the driven gear 13 and the driving gear 24. This improves the convenience of actual operation and the continuity of transmission. The rotation of the crank handle 23 drives the driving gear 24 to rotate, and the driving gear 24, through meshing, drives the two driven gears 13 to rotate synchronously. The driven gears 13 drive the adjusting bolt 12 to rotate through the rectangular slot, and the rotation of the adjusting bolt 12 drives the locking screw 11 to move closer to or away from the locking screw 11.

[0057] In use, the drive gear 24 is driven to rotate by rotating the crank 23 of the drive component 2. The drive gear 24 meshes with the two driven gears 13, causing the two driven gears 13 to rotate synchronously. Since the end of the adjusting bolt 12 is engaged with the driven gear 13 through a rectangular slot, the rotation of the driven gear 13 will cause the adjusting bolt 12 to rotate synchronously. The rotation of the adjusting bolt 12 will drive the two locking rods 11 to move closer or further away from each other synchronously, thereby adjusting the contact tightness between the locking rods 11 and the broken wire 4. When the locking rods 11 are in close contact with the broken wire 4, the force is applied by the power rod 3 to drive the locking rods 11 to rotate, thereby smoothly removing the broken wire 4 from the pipe 5.

[0058] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
