DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0028] See also Figure 1-4The utility model provides a technical solution: a combined double-top clamp for a high-voltage cable, comprising an upper clamp 1 and a lower clamp 2, wherein the upper clamp 1 and the lower clamp 2 are internally slidably connected with bolts 7, and nuts 6 are threadedly connected on the surface of the bolts 7, and a lower mounting seat 4 is fixedly installed on the side of the lower clamp 2 away from the upper clamp 1, and an upper mounting seat 18 is fixedly installed on the side of the upper clamp 1 away from the lower clamp 2, and the upper mounting seat 18 has the same internal structure as the lower mounting seat 4, and two mounting pieces 5 are internally slidably connected with the lower mounting seat 4, and racks 12 are fixedly installed on the opposite sides of the two mounting pieces 5, and two grooves 13 are provided on the two mounting pieces 5, and the two racks 12 are respectively slidably connected inside the two grooves 13, and a rotating shaft 11 is internally rotatably connected with the lower mounting seat 4, and a gear 10 is fixedly sleeved on the surface of the rotating shaft 11, and the two sides of the gear 10 are respectively meshed with the two racks 12.

[0029] Pulling one of the mounting plates 5 will move the rack 12, which will drive the gear 10 and the rotating shaft 11 to rotate, thereby driving the other rack 12 and the mounting plate 5 to move, and then the two mounting plates 5 move away from each other, so as to facilitate the adjustment of the position between the two mounting plates 5, and then facilitate the adjustment of the position of the mounting holes on the two mounting plates 5 according to the spacing between the two mounting holes on the mounting frame in the later stage, so as to facilitate the installation of the entire device, and prevent the position of the mounting holes on the two mounting plates 5 from not corresponding to the position of the mounting holes on the mounting frame, causing installation inconvenience, etc.

[0030] Two guide rods 15 are fixedly installed inside the lower mounting seat 4, and the two guide rods 15 are slidably connected with a connecting frame 14, and the two connecting frames 14 are respectively fixedly connected to the two mounting plates 5. Reset springs 16 are movably sleeved on the surfaces of the two guide rods 15, and the opposite ends of the two reset springs 16 are respectively fixedly connected to the two connecting frames 14, and the opposite ends of the two reset springs 16 are fixedly connected to the inside of the lower mounting seat 4, and the opposite ends of the two guide rods 15 are fixedly installed with limit plates 17.

[0031] By providing the limiting piece 17 , it is convenient to block the moving distance of the connecting frame 14 , thereby preventing the connecting frame 14 from excessively moving.

[0032] When the two mounting pieces 5 move, the two connecting frames 14 will follow the two mounting pieces 5 to move, and then the two connecting frames 14 will slide on the surfaces of the two guide rods 15, thereby squeezing the two return springs 16. When the two mounting pieces 5 are no longer pulled, the two mounting pieces 5 will be reset by the elastic force of the two return springs 16, thereby facilitating the retraction of the mounting pieces 5.

[0033] Rubber pads 3 are fixedly installed inside the upper clamp 1 and the lower clamp 2.

[0034] The rubber pad 3 is provided to prevent the cable from being excessively squeezed between the upper clamp 1 and the lower clamp 2 when the cable is fixed, thereby preventing the cable from being damaged.

[0036] When the docking block 8 is docked with the docking groove 9, the upper clamp 1 and the lower clamp 2 will form a closed loop. Then, through the setting of the docking block 8 and the docking groove 9, the upper clamp 1 and the lower clamp 2 can only move in one direction, thereby minimizing the separation of the upper clamp 1 and the lower clamp 2 and ensuring the stability of the device.

[0037] Working principle:

[0038] Pulling one of the mounting pieces 5 will move the rack 12, and at the same time, the rack 12 will drive the gear 10 and the rotating shaft 11 to rotate, thereby driving the other rack 12 and the mounting piece 5 to move, so that the two mounting pieces 5 move away from each other, which is convenient for adjusting the position between the two mounting pieces 5, and thus it is convenient to adjust the position of the mounting holes on the two mounting pieces 5 according to the spacing between the two mounting holes on the mounting frame in the later stage. When the two mounting pieces 5 move, the two connecting frames 14 will follow the two mounting pieces 5 to move, so that the two connecting frames 14 will slide on the surfaces of the two guide rods 15, thereby squeezing the two return springs 16. When the two mounting pieces 5 are no longer pulled, the two mounting pieces 5 will be reset by the elastic force of the two return springs 16.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
