DETAILED DESCRIPTION

[0024] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0025] The embodiment of the present application provides a quick-install post insulator, comprising an insulating portion 10, wherein a lower post 11 and an upper post 12 are respectively disposed at the bottom and the top of the insulating portion 10, and an installation assembly 20 for installing a cable is disposed at the top of the upper post 12;

[0026] The mounting assembly 20 includes a mounting seat 21 fixed to the upper support 12, a pressing member 22 and a clamping member 23;

[0027] A groove for placing cables is provided at the top of the mounting seat 21, and a hinged portion 211 and a clamping portion 212 are respectively provided at both ends of the mounting seat 21. The clamping piece 22 is hinged on the hinged portion 211 of the mounting seat 21, and the clamping piece 22 is hinged on the hinged portion 211. The clamping piece 23 is movably connected to the end of the clamping piece 22 away from the hinged portion 211, and the end of the clamping piece 23 away from the clamping piece 22 can be clamped with the clamping portion 212 of the mounting seat 21. A groove is also provided on the side of the clamping piece 22 close to the mounting seat 21. When the clamping piece 23 is clamped with the clamping portion 212, the cable is in the groove of the mounting seat 21 and the groove of the clamping piece 22.

[0028] The following is a further introduction based on specific usage scenarios.

[0029] During use, the operator inserts the lower support 11 into the transmission tower to be installed and fixes it with bolts. Then the operator places the fixed cable in the groove of the mounting seat 21. After the cable is placed, the operator does not need to tie and fix the cable. The operator only needs to rotate the clamping piece 22 to rotate the clamping piece 22 toward the mounting seat 21 until the inner wall of the groove of the clamping piece 22 clamps the cable. At this time, the operator uses the clamping piece 23 to form a clamping connection with the clamping part 212 of the mounting seat 21, completing the relative fixation of the positions of the components of the entire installation assembly 20, and also completing the installation and fixation of the cable.

[0030] It can be seen that during the entire cable installation process, the operator only needs to place the cable into the groove, and then press the clamping piece 22 onto the mounting seat 21 through the clamping piece 23 to achieve fixed installation of the cable. The operator does not need to bundle the cables, which significantly reduces the time for the operator to install the cables and significantly improves the overall work efficiency of the operator in installing the cables.

[0031] It can be noted that in the prior art, the cables are fixed by bundling. In fact, the force used to fix the cables is the combination of the friction between the bundling rope and the cables and the friction between the bundling rope and the insulators. In the embodiment of the present application, the mounting assembly 20 is fixed to the insulating part 10 by the upper support 12. The force used to fix the cables is actually the contact friction between the outer layer of the cables and the inner side of the groove of the mounting seat 21 and the inner side of the groove of the clamping piece 22. This force is the same as the force used to fix the cables by bundling in the prior art, and under the action of the clamping piece 23, the clamping piece 22 and the mounting seat 21 form a relatively fixed whole, and there is no phenomenon of the bundling rope getting loose when bundling.

[0032] In general, the embodiment of the present application is achieved by the cooperation of the mounting seat 21, the clamping piece 22 and the clamping piece 23. The operator only needs to place the cable in the groove of the mounting seat 21, and then use the clamping piece 23 to fix the cable in shape and position with the mounting seat 21, thereby significantly improving the stability of the cable fixation and the overall installation efficiency of the operator in fixing the cable.

[0033] As a feasible specific implementation method of the embodiment of the present application, an insulating half ring 214 is arranged in the groove of the mounting seat 21. The insulating half ring 214 is open at one end away from the mounting seat 21, and the cable can enter the inner side of the insulating half ring 214 through the opening of the insulating half ring 214. In the installed state, the setting of the insulating half ring 214 can reduce the gap between the cable and the inner wall of the groove of the mounting seat 21. In this way, after the clamping piece 22 and the mounting seat 21 form a card, the insulating half ring 214 actually presses the insulating outer layer of the cable, so that the insulating outer layer of the cable is forced to deform, so that the stability of the cable when fixed can be improved.

[0034] In a possible implementation of the embodiment of the present application, an insulating half ring 214 is also provided in the groove of the clamping member 22. In this way, after the clamping member 22 and the mounting seat 21 are clamped, the insulating half ring 214 substantially compresses the insulating outer layer of the cable, causing the insulating outer layer of the cable to be forced to deform, thereby improving the stability of the cable when it is fixed.

[0035] In the embodiment of the present application, the insulating half ring 214 may be elastic or inelastic.

[0036] As a feasible specific implementation of the embodiment of the present application, the clamping member 23 includes a sleeve rod 231 hinged at one end of the pressing member 22 away from the hinged portion 211, the sleeve rod 231 is hinged to the end of the pressing member 22 away from the hinged portion 211 through a pin shaft, the angle between the sleeve rod 231 and the pressing member 22 is adjustable, a movable rod 232 is movably inserted in one end of the sleeve rod 231 away from the clamping member 23, and a clamping joint 234 is fixedly connected to one end of the movable rod 232 away from the sleeve rod 231, and the clamping joint 234 can be clamped with the clamping portion 212 of the pressing member 22;

[0037] A spring 233 is disposed inside the sleeve rod 231 , and the spring 233 allows the movable rod 232 to have a tendency to move toward the sleeve rod 231 .

[0038] In combination with a specific usage scenario, when in use, the operator places the cable in the groove of the mounting seat 21, and then rotates the clamping piece 22 relative to the mounting seat 21, so that the groove of the clamping piece 22 is aligned with the cable, forming a covering and clamping of the cable. At this time, the operator rotates the sleeve rod 231, and pulls out the movable rod 232 in the sleeve rod 231, so that the clamping joint 234 of the movable rod 232 is clamped with the clamping part 212 of the mounting seat 21, so that the relative fixation of the position between the mounting seat 21 and the clamping piece 22 can be achieved. The operation is simple, which can reduce the time required for the operator to install the cable, and significantly improve the work efficiency of the operator in installing the cable.

[0039] In a possible implementation of the embodiment of the present application, the clamping column 213 is fixed at the clamping portion 212 of the mounting seat 21, and the clamping joint 234 on the movable rod 232 is hook-shaped. After the operator pulls out the movable rod 232, the clamping member 23 is rotated to make the hook-shaped clamping joint 234 at the end of the movable rod 232 hook the clamping column 213. Under the action of the spring 233, the clamping joint 234 retreats in the direction of the sleeve rod 231, so that the inner side of the hook-shaped clamping joint 234 hooks the clamping column 213, thereby keeping the positions of the mounting seat 21 and the clamping member 22 relatively fixed.

[0040] A spring 233 is provided inside the sleeve rod 231, and the spring 233 makes the movable rod 232 have a tendency to move in the direction close to the sleeve rod 231. In the embodiment of the present application, the spring 233 in the sleeve rod 231 is a compression spring, and a stopper 235 is provided at one end of the movable rod 232 located in the sleeve rod 231, and the compression spring is located on the side of the stopper 235 close to the clamping joint 234. When the operator pulls out the movable rod 232, the compression spring is compressed and deformed. After the operator completes the cooperation between the clamping joint 234 and the clamping column 213, the force of the operator on the movable rod 232 is unloaded, and the compression spring recovers part of the deformation, causing the movable rod 232 to move in the direction of the sleeve rod 231, thereby driving the clamping joint 234 to form a tight clamping connection with the clamping column 213.

[0041] Of course, in the embodiment of the present application, the spring 233 in the sleeve rod 231 can also be a tension spring, and a stopper 235 is provided at one end of the movable rod 232 located in the sleeve rod 231, one end of the tension spring is fixed at one end of the sleeve rod 231 away from the clamping joint 234, and the other end of the tension spring is fixed to the stopper 235. When the operator pulls out the movable rod 232, the tension spring is stretched and deformed. After the operator completes the coordination between the clamping joint 234 and the clamping column 213, the force of the operator on the movable rod 232 is unloaded, and the tension spring recovers part of the deformation, causing the movable rod 232 to move in the direction of the sleeve rod 231, thereby driving the clamping joint 234 and the clamping column 213 to form a tight clamping connection.

[0042] In the embodiment of the present application, the stop block 235 is cylindrical, and the outer side of the stop block 235 is in contact with the inner wall of the sleeve rod 231. This can improve the stability of the connection between the sleeve rod 231 and the movable rod 232, and improve the flexural strength of the cooperation between the sleeve rod 231 and the movable rod 232. At the same time, it can also reduce the probability of the clamping member 22 and the mounting seat 21 being detached due to the movement of the clamping member 22, thereby improving the overall stability of the device.

[0043] As a feasible specific implementation method of the embodiment of the present application, the center axis of the groove of the mounting seat 21 and the center axis of the upper pillar 12 are in the same plane and intersect vertically. In combination with a specific usage scenario, after the cable is installed on the mounting seat 21, the cable often shakes during actual use. In the embodiment of the present application, when the center axis of the groove of the mounting seat 21 and the center axis of the upper pillar 12 are in the same plane and intersect vertically, the force point of the mounting seat 21 and the disturbed point of the mounting seat 21 are close, which can increase the stability of the entire device.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
