[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] To address the problems existing in the prior art, this embodiment provides the following technical solution: an insulating pull rod comprising an insulator 1, a first insert 4, and a second insert 5. The first insert 4 is located at the left end of the insulator 1, and a first disassembly mechanism 2 is provided between the left end of the insulator 1 and the first insert 4, allowing for easy disassembly of the first insert 4 from the left end of the insulator 1. Simultaneously, a second insert 5 is located at the right end of the insulator 1, and a second disassembly mechanism 3 is provided between the right end of the insulator 1 and the second insert 5, allowing for easy disassembly of the second insert 5 from the right end of the insulator 1. The ease of assembly and disassembly of the first insert 4 and the second insert 5 facilitates their replacement and effectively avoids resource waste.
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a first insert 4 is provided on the left side of the insulator 1 and a second insert 5 is provided on the right side. The insulator 1 is made of insulating material, which can effectively isolate current and prevent electric shock. The insulator 1, the first insert 4 and the second insert 5 together constitute an insulating pull rod.
[0026] A first disassembly mechanism 2 is provided between the left end of the insulator 1 and the first insert 4, which facilitates the disassembly of the first insert 4. The first disassembly mechanism 2 includes a plug block 22, which is fixedly installed on the right end of the first insert 4 and plugged into the left end of the insulator 1. After the plug block 22 is plugged into the left end of the insulator 1, its right end is tightly fitted with the spring body 21 provided on the left side of the insulator 1. At this time, the spring body 21 is in a compressed state.
[0027] Meanwhile, the plug-in block 22 has symmetrically opened plug holes 23 inside. The plug holes 23 are engaged with the plug pins 24 on the front and back sides inside. The plug pins 24 are fixedly installed on the front and back sides inside the fixing ring 26 and slide in the sliding grooves symmetrically opened on the left side inside the insulator 1. In addition, a first spring 25 is provided on the outside of the plug pin 24. The inner end of the first spring 25 is fixedly connected to the inner side wall of the sliding grooves symmetrically opened on the left side inside the insulator 1. The outer end of the first spring 25 is fixedly connected to the front and back sides of the middle inner side of the fixing ring 26. At the same time, the interior of the fixing ring 26 is symmetrically and tightly fitted to the outer side of the left end of the insulator 1.
[0028] When the inner end of the plug pin 24 is inserted into the symmetrically opened plug holes 23 inside the plug block 22, the first spring 25 is in a compressed state, and at this time the fixing ring 26 will be tightly fitted to the front and rear sides of the left end of the insulator 1. The upper and lower sides of the fixing ring 26 have slots, and the first bolt 27 can be inserted into the slots. Then, the nut is put on the thread on the outside of one end of the first bolt 27. The internal thread of the nut can be threaded to the external thread of the first bolt 27, so that the fixing ring 26, which is similar to a clamp, is elastic and is firmly installed on the outside of the left end of the insulator 1.
[0029] Next, first unscrew the nut connected to the thread of the first bolt 27 and remove it. Then, pull the first bolt 27 out of the internal slots on the upper and lower sides of the fixing ring 26. Next, grasp the front and back sides of the fixing ring 26 and pull it outward. At this time, the first spring 25 will be stretched. At the same time, the plug pin 24 installed on the inner side of the fixing ring 26 will slide outward in the sliding groove set on the left end of the insulator 1. That is, when the plug pin 24 is pulled outward, its inner end will disengage from the plug hole 23 that is engaged. At this time, the first insert 4 can be pulled outward, and the first insert 4 can be removed from the inner left end of the insulator 1 for easy replacement. The setting of the first spring 25 ensures that the fixing ring 26 will not completely disengage from the outer left end of the insulator 1 after it is moved outward, which facilitates quick installation after the first insert 4 is replaced.
[0030] like Figure 1 , Figure 4 and Figure 5As shown, a second disassembly mechanism 3 is provided between the right end of the insulator 1 and the second insert 5, which facilitates the disassembly of the second insert 5.
[0031] The second disassembly mechanism 3 includes a plug sleeve 32, which is fixedly installed on the left end of the second insert 5 and plugged into the inside right side of the insulator 1.
[0032] A movable sleeve 33 is slidably arranged inside the insertion sleeve 32. A central rod 313 is arranged in the middle of the movable sleeve 33. The right side of the central rod 313 is fixedly connected to the middle left side of the second insert 5. A second spring 31 is arranged on the outside of the central rod 313. The left end of the second spring 31 is fixedly connected to the left end of the central rod 313, and the right end of the second spring 31 is fixedly connected to the right end of the middle part of the movable sleeve 33.
[0033] Meanwhile, a threaded hole is provided on the upper right side of the movable sleeve 33. The threaded hole is connected to the fixing pin 34. The upper side of the fixing pin 34 is slidably located inside the sliding groove 37. The sliding groove 37 is opened on the upper right side of the middle of the plug sleeve 32. The right side of the fixing pin 34 is tightly fitted with the fixing block 35. The lower end of the fixing block 35 is fixedly connected to the plug sleeve 32. At the same time, a threaded hole is opened inside the fixing pin 34. A threaded hole is also opened in the middle of the fixing block 35. The threaded hole on the inner side of the fixing pin 34 and the fixing block 35 are horizontally fitted. The threaded holes of the two are connected to the second bolt 36, which can limit the position of the fixing pin 34 and also limit the position of the movable sleeve 33 connected to the thread below. At this time, the second spring 31 between the right end of the middle of the movable sleeve 33 and the center rod 313 is in a compressed state.
[0034] Secondly, a second slot 311 is symmetrically opened on the upper and lower sides of the left middle part of the plug sleeve 32. The interior of the second slot 311 is tightly fitted with the lower outer side of the fixing ball 39. At the same time, the lower end of the fixing ball 39 is fitted with the upper left side of the plug sleeve 32. The upper left side of the plug sleeve 32 limits the position of the fixing ball 39. The upper outer side of the fixing ball 39 is tightly fitted with the third slot 312. The third slot 312 is opened on the upper and lower sides of the right middle part of the insulator 1. By engaging the fixing ball 39 inside the second slot 311 and the third slot 312, the second insert 5 can be firmly limited to the right end of the insulator 1.
[0035] When it is necessary to disassemble the second insert 5, first unscrew the second bolt 36 that is threadedly connected to the fixing pin 34 and the internal threaded hole of the fixing block 35, then pull it out, and then hold the fixing pin 34 so that it can slide to the left inside the sliding groove 37 opened on the upper right side of the middle of the insertion sleeve 32. This will drive the lower threaded movable sleeve 33 to slide to the left inside the insertion sleeve 32. When the movable sleeve 33 moves, its outer side wall will slide against the inner side wall of the insertion sleeve 32.
[0036] The first slot 38 is symmetrically opened on the upper and lower sides of the left middle of the movable sleeve 33. The first slot 38 is the same size as the second slot 311 provided on the left side inside the plug sleeve 32 and the third slot 312 provided on the right side inside the insulator 1.
[0037] When the movable sleeve 33 slides to the left, the upper left end of the movable sleeve 33 will disengage from the lower end of the fixed ball 39, and the first slot 38 inside the left side of the insertion sleeve 32 will move to the lower side of the second slot 311 and be located inside the fixed ball 39. The left end of the third spring 314 is connected to the center right side of the fixed ball 39. The right end of the third spring 314 is fixedly connected to the right side wall of the groove inside the left side of the insertion sleeve 32. When the movable sleeve 33 is not moved, the third spring 314 is in a compressed state. When the movable sleeve 33 moves, the third spring 314 connected to the right side of the fixed ball 39 will rebound from the bent and compressed state. The fixed ball 39 will enter the interior of the first slot 38 along the slope of the first slot 38. At this time, the fixed ball 39 will be located inside the second slot 311 and the first slot 38, disengaging from the third slot 312 inside the right side of the insulator 1. At this time, the second insert 5 can be removed from the right side of the insulator 1.
[0038] The working principle of this insulating tie rod is as follows: A first insert 4 is set on the left side of the insulator 1, and a first disassembly mechanism 2 is set between the insulator 1 and the first insert 4 to facilitate the disassembly of the first insert 4. At the same time, a second insert 5 is set on the right side of the insulator 1, and a second disassembly mechanism 3 is set between the insulator 1 and the second insert 5 to facilitate the disassembly of the second insert 5. The first insert 4 and the second insert 5 can be easily disassembled and replaced, which can avoid the waste of resources.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
