It cannot provide a good fastening effect when facing wires and cables of different diameters, thus having poor adaptability. Utility Model Content

[0004] The purpose of this utility model is to provide a U-shaped clamp for power installation with adjustable enclosure. A bolt is set at the rear end of the clamp, and the clamp can be replaced by the cooperation of the bolt and the bolt hole.

[0005] To achieve the above objectives, a U-shaped clamp for power installation with adjustable enclosure is provided, comprising: a vertical rod, a sliding groove provided at the left front end of the vertical rod, a screw rod rotatably connected to the inner side of the sliding groove, and a rotating ring fixedly connected to the front end of the screw rod through the vertical rod;

[0006] A slider is slidably connected to the inner side of the groove, and the inner side of the slider is threadedly connected to the screw. A movable crossbar is fixedly connected to the left side of the slider, and the movable crossbar is slidably connected to the vertical rod.

[0007] According to the aforementioned U-shaped clamp for adjustable electrical installation, a friction ring is fixedly connected to the outer side of the rotating ring.

[0008] According to the aforementioned U-shaped clamp for adjustable power installation, a horizontal bar is fixedly connected to the rear end of the vertical bar, and square grooves are provided on the inner sides of both the horizontal bar and the movable horizontal bar.

[0009] According to the aforementioned U-shaped clamp for adjustable electrical installation, both the crossbar and the movable crossbar are slidably connected to limit rods on their inner sides, and the front end of the limit rod is fixedly connected to a lever.

[0010] According to the aforementioned U-shaped clamp for adjustable power installation, a round rod is fixedly connected to the left end of the limiting rod, and a spring is provided around the periphery of the round rod, with the front end of the spring fixedly connected to the limiting rod.

[0011] According to the aforementioned U-shaped clamp for adjustable power installation, both the crossbar and the movable crossbar have screw holes on their inner sides, and bolts are threaded into the inner sides of the screw holes.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model provides an adjustable U-shaped clamp for electrical installation, which includes: a vertical rod 3, a sliding groove 8 at the left front end of the vertical rod 3, a screw 6 rotatably connected to the inner side of the sliding groove 8, and a rotating ring 10 fixedly connected to the front end of the screw 6 through the vertical rod 3;

[0027] A slider 7 is slidably connected to the inner side of the slide groove 8. The inner side of the slider 7 is threadedly connected to the screw 6. A movable crossbar 18 is fixedly connected to the left side of the slider 7. The movable crossbar 18 is slidably connected to the vertical rod 3.

[0028] A friction ring 9 is fixedly connected to the outside of the rotating ring 10. The friction ring 9 is distributed around the periphery of the rotating ring 10. The friction ring 9 can provide good friction when the rotating ring 10 is rotated, and play an anti-slip role.

[0029] The rear end of the vertical rod 3 is fixedly connected to the horizontal rod 1. Both the horizontal rod 1 and the movable horizontal rod 18 have square grooves 2 on their inner sides. The front and rear ends of the square grooves 2 have circular holes.

[0030] Both the horizontal bar 1 and the movable horizontal bar 18 are slidably connected to a limiting rod 14. The front end of the limiting rod 14 is fixedly connected to a lever 13. Moving the lever 13 can drive the limiting rod 14 to move backward.

[0031] A round rod 11 is fixedly connected to the left end of the limiting rod 14. A spring 12 is provided around the round rod 11. The front end of the spring 12 is fixedly connected to the limiting rod 14. When the limiting rod 14 moves backward, it will compress the spring 12 and cause the round rod 11 to slide along the circular hole at the front end. When the lever 13 is stopped, the spring 12 will reset, thereby pushing the limiting rod 14 forward.

[0032] Both the crossbar 1 and the movable crossbar 18 have screw holes 15 on their inner sides. Bolts 5 are threadedly connected to the inner side of the screw holes 15. The number of threads on the inner side of the screw holes 15 is such that the angle of the bolt 5 is the same before it is turned and after it is fully turned.

[0033] A limiting hole 17 is provided on the inner side of the bolt 5. The limiting hole 17 cooperates with the limiting rod 14. When the limiting rod 14 is inserted into the inner side of the limiting hole 17, it can prevent the bolt 5 from rotating.

[0034] A clamp 4 is fixedly connected to the front end of the bolt 5. A buffer plate 16 is fixedly connected to the inner side of the clamp 4. The buffer plate 16 can provide cushioning for the wires and cables when in contact with them and can provide better friction during the tightening of the clamp 4.

[0035] Working principle: During use, select a suitable size clamp 4 according to the actual installation needs. Align the bolt 5 at the rear end of the clamp 4 with the screw hole 15 inside the crossbar 1 and movable crossbar 18. After placing the clamp 4 horizontally, align the bolt 5 at the rear end of the clamp 4 with the screw hole 15. At this time, move the lever 13 to move the rear limit rod 14 backward along the circular hole inside the square groove 2. The movement of the limit rod 14 compresses the rear spring 12 and causes the round rod 11 to move backward along the circular hole at the left end inside the square groove 2. Then, tighten the bolt 5 until it is fully in contact with the screw hole 15. Loosen the lever 13, and under the reset of the spring 12, push the limit rod 14 forward, thereby making the limit rod 14 contact the bolt 5. The limiting hole 17 at the end fits tightly, thus preventing the bolt 5 from rotating during use. After the clamp 4 wraps around the wire and cable, the rotating ring 10 is rotated. The outer side of the rotating ring 10 is provided with a friction ring 9, which can provide good friction when rotating the rotating ring 10, thus playing an anti-slip role. The rotation of the rotating ring 10 drives the screw 6 to rotate synchronously. Under the action of the threaded connection, the slider 7 slides along the inner side of the slide groove 8. The sliding of the slider 7 drives the movable crossbar 18 to move, thereby driving the clamp 4 at the front end to move. The clamp 4 is provided with a buffer plate 16 on the inner side. The buffer plate 16 can play a good buffering effect, and the buffer plate 16 can provide good friction when in close contact with the wire and cable.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
