Description

Technical Field

[0001] The present invention relates to the technical field of broken wire treatment of threaded pipe fittings, and in particular to a device for removing broken wires from threaded pipe fittings. Background Art

[0002] Threaded pipe fittings are a type of connector used in pipe systems, usually for connecting two pipes or pipelines. This type of connector uses threaded connections, which are designed such that the pipes can be connected and fixed together by threading. Among them, a faucet is a common threaded pipe fitting. During long-term use, the connection end between the threaded pipe fitting and the water pipe may have problems of rust and corrosion. During the process of disassembly and replacement, excessive force may cause partial fracture at the connection between the threaded pipe fitting and the water pipe, making it difficult to remove the broken wire part located inside the water pipe.

[0003] The existing threaded pipe fittings have the following problems when broken wires need to be removed: users mainly use some conventional clamping tools, such as pliers or wrenches, to insert into the broken wire part of the threaded pipe fitting inside the water pipe and turn it to remove the broken wire part. In this way of operation, there is a situation of slipping during the force application due to insufficient clamping, and it is difficult to quickly and efficiently remove the broken wire part of the threaded pipe fitting. Therefore, corresponding technical solutions need to be designed to solve the existing technical problems.

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0027] As Figure 1 and in combination with Figures 2 to 5 shown, a device for removing broken wires from a threaded pipe fitting includes a pair of jaws 1, a pair of handles 2, and a force application mechanism 3. The pair of jaws 1 is connected to the pair of handles 2, and the force application mechanism 3 is arranged on the pair of handles 2.

[0028] Furthermore, the pair of jaws 1 includes a first jaw head 11 and a second jaw head 12. The first jaw head 11 is connected with a disc body 13, the disc body 13 is provided with a socket 14, the second jaw head 12 is connected with a plug rod 15, and the plug rod 15 is rotatably inserted into the socket 14.

[0029] Beneficial effects of the further technical solution: This structure enables the first jaw head 11 and the second jaw head 12 to rotate relative to each other, flexibly changing the opening and closing degree of the pair of jaws 1. Whether it is a threaded pipe fitting with different pipe diameters or a broken wire in a narrow space, the device can handle it with ease, greatly expanding the applicable scenarios.

[0030] Further, a plurality of anti-slip threads 16 are provided on the surface of one end of the jaw 1, and thread patterns 17 are provided outside the anti-slip threads 16.

[0031] Beneficial effects of the further technical solution: When the jaw 1 contacts the broken wire, the anti-slip threads 16 and the thread patterns 17 cooperate to increase the friction force with the broken wire, effectively preventing the broken wire from slipping and loosening during the removal process, ensuring the stability of the clamping state, and greatly improving the success rate of removing the broken wire.

[0032] Further, the anti-slip threads 16 are integrally connected to the surface of the jaw 1.

[0033] Beneficial effects of the further technical solution: The anti-slip threads 16 and the surface of the jaw 1 are of an integral structure, ensuring the firmness of the connection between the two and fundamentally eliminating the possibility of the anti-slip threads 16 falling off. At the same time, the integral design simplifies the production process, reduces the quality hidden dangers caused by the connection part, extends the service life of the device, and improves the overall reliability of the product.

[0034] Further, the pliers handle 2 includes a first pliers rod 21 and a second pliers rod 22. The first pliers rod 21 is threadedly connected to the first pliers head 11, and the second pliers rod 22 is threadedly connected to the second pliers head 12.

[0035] Beneficial effects of the further technical solution: This connection method makes the disassembly and assembly of the device very convenient, reducing the difficulty and cost of maintenance. In addition, the user can flexibly replace the pliers head and pliers rod of different specifications according to the actual operation requirements, further enhancing the practicability of the device.

[0036] Further, a first threaded opening 23 is provided in the middle of the first pliers rod 21, and a second threaded opening 24 is provided at the end of the second pliers rod 22.

[0037] Beneficial effects of the further technical solution: It provides a suitable interface for the installation of the force application mechanism 3. This design ensures the stability of the installation of the force application mechanism 3, ensures the coordinated cooperation of the components of the device during the working process, and creates conditions for successfully removing the broken wire.

[0038] Further, the force application mechanism 3 includes a screw rod 31 and a force application rod 32. The screw rod 31 is threadedly connected to the first threaded opening 23, and the force application rod 32 is threadedly connected to the second threaded opening 24.

[0039] Beneficial effects of the further technical solution: By rotating the screw rod 31 and the force application rod 32, the user can precisely control the clamping force of the jaw 1 and the angle of applying force to the broken wire, significantly improving the accuracy and convenience of the operation, and making the broken wire removal work more efficient.

[0040] Further, a force - applying head 33 is provided at the upper end of the screw rod 31, an anti - slip outer sleeve 34 is provided at the upper end of the force - applying rod 32, and a limit nut 35 is provided on the second pliers handle 22 near the second thread opening 24. A contact head 36 is provided at the lower end of the screw rod 31, and the contact head 36 abuts against the second pliers handle 22.

[0041] Beneficial effects of the further technical solution: The force - applying head 33 at the upper end of the screw rod 31 conforms to the ergonomic design, which is convenient for the user to grip and apply force to rotate the screw rod 31; the anti - slip outer sleeve 34 at the upper end of the force - applying rod 32 increases the friction between the hand and the force - applying rod, avoiding the hand from sliding during operation. The limit nut 35 provided on the second pliers handle 22 near the second thread opening 24 can prevent the force - applying rod 32 from being screwed in or out excessively, ensuring the normal operation of the device and effectively avoiding safety accidents caused by improper operation, thus enhancing the safety during use.

[0042] Compared with the prior art, the beneficial effects of the present invention are as follows: The pliers jaws 1 open and close flexibly, and can easily adapt to broken wires of different sizes and positions, greatly enhancing the applicability of the device; the anti - slip threads 16 and the tooth patterns 17 increase the friction between the pliers jaws 1 and the broken wire, and can firmly grip the broken wire when removing it, effectively avoiding the slipping phenomenon and ensuring the stability and reliability of the operation; the user can flexibly control the magnitude and direction of the applied force by adjusting the screw rod 31 and the force - applying rod 32, so as to precisely remove the broken wire. At the same time, the force - applying head 33 on the screw rod 31, the anti - slip outer sleeve 34 on the force - applying rod 32, and the limit nut 35 on the second pliers handle 22 further improve the convenience and safety of the operation.

[0043] Working principle, as Figure 5 shown:

[0044] Step 1. Device preparation: Check whether the pliers jaws 1, the pliers handles 2 and the force - applying mechanism 3 are intact, and whether the connections of all components are firm. Ensure that the threaded connections between the first pliers rod 21 and the first pliers head 11, and between the second pliers rod 22 and the second pliers head 12 are tight, the cooperation between the screw rod 31 and the first thread opening 23, and between the force - applying rod 32 and the second thread opening 24 is normal, and the position of the limit nut 35 is appropriate.

[0045] Step 2. Adjust the pliers jaws 1: According to the position and size of the broken wire 5 in the water pipe 4, flexibly rotate and adjust the opening and closing angles of the first pliers head 11 and the second pliers head 12 through the socket 14 and the insertion rod 15 on the disc body 13, so that the pliers jaws 1 can accurately align with the broken wire.

[0046] Step 3. Clamp the broken wire: Hold the pliers handle 2 by hand, bring the end of the pliers jaws 1 with the anti - slip threads 16 and the tooth patterns 17 close to the broken wire 5, firmly grip the pliers handle 2, so that the anti - slip threads 16 and the tooth patterns 17 tightly bite the broken wire 5, and use the increased friction between the two to ensure that the broken wire is firmly clamped.

[0047] Step 4. Apply force: Rotate the force - applying head 33 to adjust the position of the screw rod 31 in the first threaded opening 23; at the same time, hold the anti - slip jacket 34 on the force - applying rod 32 and adjust the position of the force - applying rod 32 in the second threaded opening 24, so as to control the magnitude and direction of the force applied to the jaw 1. Gradually increase the force, and with the coordinated transmission among the jaw 1, the pliers handle 2 and the force - applying mechanism 3, smoothly remove the broken wire from the pipe fitting.

[0048] Example 1: Removing a broken wire from an industrial pipeline

[0049] Scene description: During the daily inspection of an industrial cooling pipeline system in a factory, a broken - wire problem was found in a threaded pipe fitting. This pipeline system is used for cooling large equipment, has a relatively large pipe diameter, the position of the broken wire is relatively concealed, and the surrounding environment is complex, with other pipelines and equipment obstructing the operation space.

[0050] Device preparation: Use a device for removing broken wires from threaded pipe fittings equipped specifically for industrial scenarios. Conduct a comprehensive inspection of the device, with a focus on confirming whether there are any damages or looseness of each component in the industrial environment. Ensure that the threaded connections between the first pliers rod 21 and the first jaw 11, and between the second pliers rod 22 and the second jaw 12 are tight, because the operation of industrial pipelines requires bearing greater forces. At the same time, check whether the cooperation between the screw rod 31 and the first threaded opening 23, and between the force - applying rod 32 and the second threaded opening 24 is smooth, and whether the state of the limit nut 35 is normal.

[0051] Adjust the jaw: Since the industrial pipeline has a relatively large diameter and the position of the broken wire is concealed. Through the socket 14 and the insertion rod 15 on the disc body 13, greatly open the opening and closing angle of the first jaw 11 and the second jaw 12 to adapt to the broken wire in the large - diameter pipe. At the same time, utilize the flexibility of the device to adjust the jaw 1 to be able to bypass the surrounding obstacles and accurately align with the position of the broken wire.

[0052] Clamp the broken wire: In the complex industrial environment, the worker holds the pliers handle 2 and brings the end of the jaw 1 with the anti - slip wire 16 and the thread pattern 17 close to the broken wire. Despite the inconvenient surrounding operation, with the synergistically increased friction of the anti - slip wire 16 and the thread pattern 17, after firmly gripping the pliers handle 2, the broken wire is firmly clamped and remains stable during subsequent operations.

[0053] Apply force: The worker holds the force - applying head 33 and the anti - slip jacket 34 on the force - applying rod 32 with both hands. According to the actual situation of the broken wire, precisely rotate the force - applying head 33 and the force - applying rod 32 to adjust the positions of the screw rod 31 and the force - applying rod 32, thereby accurately controlling the magnitude and direction of the force applied to the jaw 1. Under the complex conditions of the industrial environment, through the coordinated action of the jaw 1, the pliers handle 2 and the force - applying mechanism 3, successfully overcome the greater resistance and smoothly remove the broken wire from the industrial pipeline fitting, ensuring the normal operation of the industrial cooling pipeline system.

[0054] Example Two: Removing Broken Threads from Household Water Pipes

[0055] Scenario Description: During daily household repairs, it was found that there was a water leakage at the connection of the household water pipe under the washbasin in the bathroom. After inspection, it was found that the threaded pipe fitting was broken, and the broken thread part remained inside the fitting, and it was necessary to remove it in order to replace the new fitting.

[0056] Device Preparation: Take out the device for removing broken threads from the threaded pipe fitting and carefully check each component of the jaw 1, the handle 2, and the force application mechanism 3. Ensure that the threaded connections between the first jaw rod 21 and the first jaw head 11, and between the second jaw rod 22 and the second jaw head 12 are firm without any signs of looseness. At the same time, check the mating situation between the screw rod 31 and the first threaded port 23, and between the force application rod 32 and the second threaded port 24. Rotate the screw rod 31 and the force application rod 32 to feel their smoothness, and confirm that the position of the limit nut 35 is correct and will not affect subsequent operations.

[0057] Adjust the Jaws: Observe the position of the broken thread. Since it is in a narrow space under the washbasin and the diameter of the broken thread is small. Through the socket 14 and the insertion rod 15 on the disc body 13, adjust the opening and closing angle of the first jaw head 11 and the second jaw head 12 to an appropriate size so that the jaw 1 can smoothly enter the narrow space and align with the broken thread.

[0058] Clamp the Broken Thread: Carefully hold the handle 2 by hand, and bring the end of the jaw 1 with the anti-slip thread 16 and the thread pattern 17 close to the broken thread. In the limited operating space, firmly hold the handle 2 to make the anti-slip thread 16 and the thread pattern 17 tightly bite the broken thread. Despite the narrow space, due to the increased friction of the anti-slip thread 16 and the thread pattern 17, the broken thread is firmly clamped without any slipping phenomenon.

[0059] Apply Force: Hold the force application head 33 with one hand and slowly rotate it to adjust the position of the screw rod 31 in the first threaded port 23. At the same time, hold the anti-slip sleeve 34 on the force application rod 32 with the other hand and adjust the position of the force application rod 32 in the second threaded port 24. In the narrow space, precisely control the magnitude and direction of the force applied to the jaw 1. As the applied force gradually increases, the jaw 1, the handle 2, and the force application mechanism 3 cooperate to conduct the force, and the broken thread is successfully removed from the fitting, successfully completing the repair task.
