DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0027] Embodiment:

[0028] Please refer to Figures 1 to 5 The utility model provides a technical scheme:

[0029] A kind of deflecting-resistant insulator fixture of multi-tower type, comprising:

[0030] The connecting plate 1 has a plurality of mounting holes 5 on it for mounting the connecting block 2 or the supporting plate. The supporting plate is divided into a first supporting plate 3 and a second supporting plate 4. The lower end of the first supporting plate 3 is fixedly connected with a first lead screw 7. The lower end of the second supporting plate 4 is fixedly connected with a second lead screw 9. The bottom of the first lead screw 7 and the second lead screw 9 is installed with an insulator fixture 11. The insulator fixture 11 is provided with two half-moon-shaped anti-skid plates 15. The rear end of the anti-skid plate 15 is connected to the adjusting assembly in the upper fixture 12 and the lower fixture 13 through a sliding sleeve 20.

[0031] In this embodiment, the insulator may be deflected during installation. To prevent this, two symmetrical anti-skid plates 15 are arranged in the fixture. When the insulator is placed in the fixture, the insulator is in contact with the anti-skid plates 15. The sliding sleeve 20 connected to the top end of the anti-skid plate 15 moves in the direction of the adjusting bolt 16 in the circular sliding groove 19 to the top of the circular sliding groove 19 under the force. Since the circular sliding groove 19 and the sliding sleeve 20 are installed with a return spring 21, and the return spring 21 is sleeved outside the adjusting bolt 16, the return spring 21 is compressed when the sliding sleeve 20 moves to the top of the circular sliding groove 19. The return spring 21 thus provides a restoring force to the sliding sleeve 20, which drives the anti-skid plate 15 to firmly contact the anti-skid plate 15, thereby completely fixing the insulator and preventing deflection.

[0032] Meanwhile, there are many types of insulators on the market. Different sizes of fixtures may be needed for different sizes of insulators. To save costs, the adjusting bolt 16 is arranged in the sliding sleeve 20 of the insulator fixture 11. The adjusting bolt 16 is fixed in the fixture by a limiting ring 17. When the adjusting bolt 16 is twisted, the adjusting bolt 16 does not move, so that the nut 18 on the adjusting bolt 16 moves vertically. Since the circular sliding groove 19 is fixedly connected below the nut 18, the position of the anti-skid plate 15 can be changed by twisting the adjusting bolt 16 to adapt to different sizes of insulators.

[0033] Specifically, as shown in Figure 3 The adjusting assembly includes a nut 18, which is sleeved on the adjusting bolt 16. The lower end of the nut 18 is fixedly connected with a circular sliding groove 19. The sliding sleeve 20 is slidably connected in the circular sliding groove 19. The top end of the sliding sleeve 20 is fixedly connected with a return spring 21, which is sleeved outside the bolt. The other end of the return spring 21 is fixedly connected to the lower end face of the top of the circular sliding groove 19.

[0034] Specific, the adjusting bolt 16 passes through the nut 18, the reset spring 21, the circular sliding groove 19 hidden in the upper clamp 12 or the lower clamp 13, and the sliding sleeve 20 fixedly connected to the top of the anti-skid plate 15.

[0035] Specific, the adjusting bolt 16 is limited by the limiting ring 17 below the nut, and the limiting ring 17 cooperates with the nut to limit the adjusting bolt 16 in the upper clamp 12 or the lower clamp 13.

[0036] Specific, the upper clamp 12 and the lower clamp 13 are fixed by the side fixing bolt 14, and the upper clamp 12 and the lower clamp 13 are clamped and hinged on the other side.

[0037] As shown in the embodiment, Figure 4 The connecting plate 1 can be used for installing two groups of insulator clamps 11 at the same time, and the connecting plate 1 can be additionally installed through the connecting block 2, so that more insulator clamps 11 can be used side by side. The design of the multiple-tower type can adjust the installation position of the insulator clamp 11 according to the spacing between the insulator strings. One connecting plate 1 can be used for installing 1-2 insulator clamps 11, or the connecting plate 1 can be used as a connecting plate without installing the clamp.

[0038] Specific, the first supporting plate 3 is installed in the mounting hole 5 in the middle of the connecting plate 1, and the second supporting plate 4 is installed in the mounting hole 5 on both sides of the connecting plate 1.

[0039] Specific, the bottom of the connecting plate 1 is provided with a fixing hole 6 for connecting and fixing an insulator steel cap, and the mounting hole 5 on both sides of the top end of the connecting plate 1 is used for cooperating with the connecting block 2 to complete the additional installation of another connecting plate 1. The surface of the connecting block 2 is provided with a connecting hole 202 consistent in size with the mounting hole 5, and the top plate of the connecting block 2 is provided with a reinforcing plate 201 between the center connecting clamping plate.

[0040] Specific, the middle part of the first lead screw 7 and the second lead screw 9 is sleeved with a ring sleeve 8, and the ring sleeve 8 is provided with an adjusting rod 10 for adjusting the spacing of the insulators.

[0041] In use, according to the spacing and number of the insulator strings at the construction site, the corresponding number of the first supporting clamps 3 and the second supporting plates 4 are installed on the connecting plate 1. The upper clamp 12 of the insulator clamp 11 is opened through the fixing bolt 14, the insulator is put into the clamp, the insulator abuts against the anti-skid plate 15, the sliding sleeve 20 connected to the top end of the anti-skid plate 15 moves in the direction of the adjusting bolt 16 in the circular sliding groove 19 under the action of force, and the reset spring 21 is pressed during the movement. The reset spring 21 provides a reset force for the sliding sleeve 20, drives the anti-skid plate 15 to abut against the anti-skid plate 15, and completely fixes the insulator to prevent deflection.

[0042] If the size of the insulator is not matched with the insulator fixture 11, the adjusting bolt 16 is screwed, the adjusting bolt 16 does not move, the nut 18 on the adjusting bolt 16 moves vertically, the circular sliding groove 19 fixedly connected below the nut 18 drives the reset spring 21 and the sliding sleeve 20 fixedly connected inside to move vertically, thereby changing the position of the anti-skid plate 15 to adapt to different sizes of the insulator.

[0043] The rest of the utility model not described part can be same with prior art, or for well-known technology or can adopt prior art to realize, here no longer detailed.

[0044] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
