[0029] Figure 1 The cable joint disassembly tool 10 in some embodiments of the present utility model is shown, and the cable joint disassembly tool 10 is used for disassembling the cable joint 3.

[0030] As Figure 1 and Figure 2 shown, the cable joint disassembly tool 10 is used for disassembling the cable joint 3. The cable joint 3 includes a columnar portion 31 and a movable ring 32. The movable ring 32 is movably arranged on the columnar portion 31, and a plurality of tooth bite grooves 33 are formed in the circumferential direction of the movable ring 32.

[0031] It can be understood that the columnar portion 31 is generally cylindrical. One end of it is used for installing the movable ring 32, and the other end is used for inserting and installing the cable. An internal thread is formed on the movable ring 32, and the internal thread is used for corresponding screwing to the corresponding interface, so that the cable can be connected to the corresponding interface.

[0032] The cable joint disassembly tool 10 includes a lever arm assembly 1 and a disassembly assembly 2, and the disassembly assembly 2 is arranged on the lever arm assembly 1. The lever arm assembly 1 is used to transfer torque to the disassembly assembly 2.

[0033] As Figures 1 to 3 shown, the lever arm assembly 1 has a tool end 11.

[0034] Understandably, the tool end 11 is used to fix the disassembly assembly 2.

[0035] The disassembly assembly 2 includes a connecting portion 123, a jaw portion 22 and a plurality of profiling teeth 23. The connecting portion 123 connects the jaw portion 22. One end of the connecting portion 123 is connected to the tool end 11 of the lever arm assembly 1, and the other end of the connecting portion 123 is connected to the jaw portion 22. The jaw portion 22 has a profiling surface 221, and the profiling surface 221 corresponds to the outer diameter of the cable joint 3. Each profiling tooth 23 is arranged on the profiling surface 221, and the profiling teeth 23 are symmetrically distributed. When the jaw portion 22 is positioned and abutted against the columnar portion 31, the profiling surface 221 abuts against the outer side surface of the circumferential edge of the columnar portion 31, and each jaw portion 22 is correspondingly engaged into a tooth biting groove 33, so that the lever arm assembly 1 can drive the movable collar 32 to rotate.

[0036] Understandably, the connecting portion 123 is used to connect the tool end 11 of the lever arm assembly 1 and the jaw portion 22 of the disassembly assembly 2. The jaw portion 22 has a profiling surface 221, and the design of the profiling surface 221 matches the outer diameter of the columnar portion 31 of the cable joint 3 to ensure a tight fit. The profiling teeth 23 are evenly distributed on the profiling surface 221 of the jaw portion 22 and are symmetrically distributed to better cooperate with the tooth biting grooves 33 on the cable joint 3.

[0037] It should be noted that when it is necessary to disassemble the cable joint 3, the jaw portion 22 of the disassembly assembly 2 is aligned with the columnar portion 31 of the cable joint 3, so that the profiling surface 221 abuts against the outer side surface of the circumferential edge of the columnar portion 31. At this time, each profiling tooth 23 will correspondingly engage into a tooth biting groove 33 on the cable joint 3. In this way, when the lever arm assembly 1 rotates, the movable collar 32 of the cable joint 3 can be driven to rotate through the disassembly assembly 2 to achieve the purpose of disassembly.

[0038] It should also be noted that when the jaw portion 22 is correspondingly assembled to the columnar portion 31, the profiling surface 221 is configured not to cover more than half of the contour in the circumferential direction of the columnar portion 31, ensuring that the columnar portion 31 can smoothly fall into the jaw portion 22 and preventing the columnar portion 31 from getting stuck outside the jaw portion 22.

[0039] As Figures 1 to 3As shown, in some embodiments of the cable joint disassembly tool 10, the lever arm assembly 1 includes a lever arm 12. The lever arm 12 includes a gripping portion 121, a folding portion 122, and a connecting portion 123 that are sequentially connected. The tool end 11 is located on the connecting portion 123 at a position away from the folding portion 122.

[0040] Understandably, the gripping portion 121 is used to provide a position for the operator to grip, facilitating the application of torque. The user rotates the lever arm 12 by gripping this portion, and the lever arm 12 then drives the disassembly assembly 2 to rotate. The operator holds the gripping portion 121 and rotates it clockwise or counterclockwise to transmit torque, which plays a role in saving effort.

[0041] The setting of the folding portion 122 enables the lever arm assembly 1 to adapt to different working space requirements. Usage method: Manually adjust the angle of the folding portion 122 according to the limitations of the actual working space, which improves the flexibility of the tool and is applicable to narrow or restricted spaces.

[0042] The connecting portion 123 is used to connect the lever arm assembly 1 and the disassembly assembly 2. It not only plays a connecting role but also is responsible for accurately transmitting the torque transmitted by the lever arm 12 to the disassembly assembly 2.

[0043] Specifically, as Figure 1 shown, the length extension direction of the gripping portion 121 intersects with the length extension direction of the folding portion 122 at an angle of 45° to 65°.

[0044] Specifically, as Figure 1 shown, the length extension direction of the folding portion 122 intersects with the length extension direction of the connecting portion 123 at an angle of 45° to 65°. The gripping portion 121 and the connecting portion 123 are parallel to each other.

[0045] Understandably, the angle data in this embodiment can be flexibly selected and specifically set according to the actual operation space to ensure the convenience of use, etc.

[0046] As Figures 1 to 3 shown, in some embodiments of the cable joint disassembly tool 10, the lever arm assembly 1 further includes a rubberized portion 13, and the rubberized portion 13 is arranged outside the gripping portion 121.

[0047] Understandably, the rubberized portion 13 is used to improve the gripping comfort and anti-slip performance of the gripping portion 121. The rubberized portion 13 is arranged outside the gripping portion 121 and is usually made of soft materials such as rubber or thermoplastic elastomer (TPE), which have good touch and anti-slip characteristics. The operator grips the rubberized portion 13 to rotate the lever arm 12, and the torque is transmitted through the rubberized portion 13. The rubberized portion 13 improves the operator's gripping comfort, reduces hand fatigue, and enhances the gripping stability, especially when working in a wet or greasy environment.

[0048] AsFigures 1 to 3 As shown, in some embodiments of the cable joint disassembly tool 10, the gripping portion 121, the angled portion 122, and the connecting portion 123 are integrally formed structures.

[0049] It can be understood that the integrally formed structure improves the overall strength and rigidity of the lever arm 12, reduces the risk of wear or breakage due to long-term use, and extends the service life of the tool.

[0050] As Figure 2 and Figure 3 shown, in some embodiments of the cable joint disassembly tool 10, the cable joint disassembly tool 10 includes a plurality of disassembly components 2. The surface profiles of at least some of the profiling surfaces 221 are different, and the dimensional specifications of the profiling teeth 23 of any one disassembly component 2 are different from those of the profiling teeth 23 of the remaining disassembly components 2. Each mounting portion 21 is detachably inserted into the tool end 11.

[0051] It can be understood that the cable joint disassembly tool 10 includes a plurality of disassembly components 2. Among these disassembly components 2, the surface profiles of at least some of the profiling surfaces 221 are different, and the dimensional specifications of the profiling teeth 23 on each disassembly component 2 are also different. In this way, the appropriate disassembly component 2 can be selected according to the size of the different cable joints 3 for the disassembly work. The operator can select the appropriate disassembly component 2 according to the size of the cable joint 3 and insert the mounting portion 21 of the disassembly component 2 into the tool end 11 to achieve quick replacement.

[0052] It should be noted that by providing disassembly components 2 with various dimensional specifications, the same tool can be applied to cable joints 3 of different sizes, greatly improving the versatility and applicable range of the cable joint disassembly tool 10.

[0053] As Figure 3 shown, in some embodiments of the cable joint disassembly tool 10, each mounting portion 21 is provided with a plug post 211, and the plug post 211 is detachably inserted into the tool end 11.

[0054] It can be understood that by aligning the mounting portion 21 of the disassembly component 2 with the tool end 11 and then inserting the plug post 211 into the mounting portion 21, the fixation of the disassembly component 2 is achieved, further improving the convenience of tool use.

[0055] Preferably, the cross-section of the plug post 211 is configured as a regular or irregular polygon and is configured to be adapted to the contour of the insertion position, thereby preventing relative rotation between the plug post 211 and the mounting portion 21 and ensuring the stability of the cable joint disassembly tool 10.

[0056] Specifically, in some embodiments of the cable joint disassembly tool 10, connection threads are provided on each mounting portion 21, and the connection threads are screwed onto the mounting portion 21.

[0057] It can be understood that the connection stability between the disassembly component 2 and the force arm component 1 is improved. Connection threads are provided on the mounting portion 21 of each disassembly component 2, and the connection threads cooperate with the corresponding threads on the tool end 11. The disassembly component 2 is connected to the tool end 11 of the force arm component 1 through threaded connection. Through the design of the connection threads, the reliable connection between the disassembly component 2 and the force arm component 1 is ensured, the overall stability of the tool is improved, and it is convenient to quickly replace the disassembly components 2 of different size specifications.

[0058] In other embodiments, the mounting portion 21 and the tool end 11 can be configured to be snap-connected. The snap-connection method has the advantage of quick installation and improves the convenience of use of the cable joint disassembly tool 10.

[0059] Such as Figures 1 to 3 shown, in some embodiments of the cable joint disassembly tool 10, each profiling tooth 23 is provided with a tooth-biting profiling surface 231 at a position away from the tooth mouth portion 22 (the tooth-biting profiling surface 231 is shown in Figure 1 and Figure 3 ), and the tooth-biting profiling surface 231 is adapted to the bottom of the tooth-biting groove 33.

[0060] It can be understood that the tooth-biting profiling surface 231 improves the fitting accuracy between the disassembly component 2 and the cable joint 3. The operator aligns the tooth mouth portion 22 of the disassembly component 2 with the columnar portion 31 of the cable joint 3, aligns and inserts the tooth-biting profiling surface 231 with the bottom of the tooth-biting groove 33. In this way, the precise fitting between the disassembly component 2 and the cable joint 3 is achieved. Through the setting of the tooth-biting profiling surface 231, the high-precision fitting between the disassembly component 2 and the cable joint 3 is ensured, the operation stability and reliability of the tool are improved, and the possibility of damaging the cable joint 3 during the disassembly process is reduced.

[0061] For cable joints 3 of certain specifications, two of the tooth mouth portions 22 can be located at the left and right edges of the tooth mouth portion 22 respectively, so that the cable joint disassembly tool 10 can disassemble the corresponding cable joints 3.

[0062] Implementing the present utility model has the following beneficial effects:

[0063] The utility model relates to a cable joint disassembly tool. On the cable joint disassembly tool, by setting a profiling tooth that matches the tooth bite groove on the cable joint movable ring, it can effectively be inserted into the tooth bite groove to ensure that the movable ring can be accurately driven to rotate when applying torque, avoiding the slipping phenomenon caused by the traditional tool due to insufficient biting, improving the disassembly efficiency and operation safety. By fitting the profiling surface to the columnar part of the cable joint, the damage to the joint itself during the disassembly process is reduced, and the service life of the cable joint is prolonged. Since the tooth part of the disassembly tool can accurately be embedded into the tooth bite groove of the cable joint, it can be more accurately positioned during reinstallation, ensuring the installation accuracy of the cable joint and reducing the failure rate caused by improper installation.
