Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] An adjustable bundled wire clamp includes an upper wire clamp 1 and a lower wire clamp 2. Two first arc-shaped clamping grooves 201 are provided at the top of the lower wire clamp 2, and two second arc-shaped clamping grooves 101 that cooperate with the first arc-shaped clamping grooves 201 are provided at the bottom of the upper wire clamp 1. The radius of the first arc-shaped clamping groove 201 is greater than that of the second arc-shaped clamping groove 101. Serrated anti-slip grooves are provided on the inner walls of the first arc-shaped clamping groove 201 and the second arc-shaped clamping groove 101.

[0029] An inner concave is provided at the top of the upper wire clamp 1, and an upper pressing plate 3 is provided at the inner concave. A fixing bracket 4 is provided at the bottom of the lower wire clamp 2, and a lower pressing plate 5 is provided at the bottom of the fixing bracket 4. A locking bolt 6 is provided on the upper wire clamp 1. The bottom of the locking bolt 6 sequentially penetrates through the upper pressing plate 3, the upper wire clamp 1, the lower wire clamp 2, the fixing bracket 4, and the lower pressing plate 5, and is threadedly connected to a locking nut 7 for fixing the upper pressing plate 3, the upper wire clamp 1, the lower wire clamp 2, the fixing bracket 4, and the lower pressing plate 5 together.

[0030] As Figure 1 、 Figure 2 and Figure 3 and Figure 4 show, the wire to be clamped can pass through between the first arc-shaped clamping groove 201 and the second arc-shaped clamping groove 101. By using the cooperation of the locking bolt 6 and the locking nut 7, the upper pressing plate 3, the upper wire clamp 1, the lower wire clamp 2, the fixing frame 4 and the lower pressing plate 5 are fixed together. At this time, the upper wire clamp 1 and the lower wire clamp 2 fix the wire. Loosen the locking nut 7, and the upper wire clamp 1 and the lower wire clamp 2 can be separated to remove the fixed wire.

[0031] Both sides of the fixing frame 4 are fixedly connected with wedge blocks 8. One side of the fixing frame 4 is provided with a pull rod 9. Both ends of the pull rod 9 pass through the wedge blocks 8 and are threadedly connected with fixing nuts 10.

[0032] As Figure 1 and Figure 2 show, the wedge blocks 8 have openings, so that both ends of the pull rod 9 can pass through the wedge blocks 8 on both sides of the fixing frame 4 respectively.

[0033] The locking bolt 6 includes a bolt body 601 and a bolt cap 602. The bolt body 601 and the bolt cap 602 are fixedly connected. A rectangular limiting portion 603 is fixedly connected to the outer surface of the bolt body 601 and at the bottom of the bolt cap 602.

[0034] As Figure 2 、 Figure 3 、 Figure 4 and Figure 5 show, the bolt body 601 has threads and can be threadedly connected with the locking nut 7. The bolt cap 602 presses the upper pressing plate 3 from above, and the locking nut 7 presses the lower pressing plate 5 from below, so that the upper pressing plate 3 and the lower pressing plate 5 apply pressure to approach each other, and the upper wire clamp 1 and the lower wire clamp 2 are pressed together.

[0035] Round holes 11 for the bolt body 601 to pass through are formed in the lower wire clamp 2. Rectangular positioning notches 12 are formed in the upper pressing plate 3 and the upper wire clamp 1. The rectangular positioning notches 12 are adapted to the rectangular limiting portions 603.

[0036] As Figure 4 and Figure 5 show, the rectangular positioning notches 12 are located above the round holes 11, so that when the bolt body 601 passes through the round holes 11, the rectangular limiting portions 603 are located in the rectangular positioning notches 12 to assist in positioning the locking nut 6 and prevent the locking bolt 6 from rotating.

[0037] An inner concave chamber 13 is formed at the bottom of the lower wire clamp 2, and a plurality of anti-slip convex blocks 14 are fixedly connected in the inner concave chamber 13.

[0038] As Figure 8, the anti-slip bumps 14 are used to increase the friction at the bottom of the lower wire clamp 2, which can improve the anti-slip ability between the bottom of the lower wire clamp 2 and the fixing frame 4.

[0039] A positioning card shaft 15 is fixedly connected to the bottom of the upper wire clamp 1, and a positioning card slot 16 is opened at the top of the lower wire clamp 2. The positioning card shaft 15 and the positioning card slot 16 are adapted to each other.

[0040] Such as Figure 6 and Figure 7 , when the upper wire clamp 1 and the lower wire clamp 2 approach each other, the positioning card shaft 15 can be inserted into the positioning card slot 16. While making the upper wire clamp 1 and the lower wire clamp 2 quickly aligned, it can also prevent relative sliding between the upper wire clamp 1 and the lower wire clamp 2.

[0041] Compared with the related art, a kind of adjustable bundled wire clamp provided by the present utility model has the following beneficial effects:

[0042] The present utility model can clamp the circuit through the upper wire clamp 1 and the lower wire clamp 2 to realize the function of bundling wires. At the same time, since the radius of the first arc-shaped clamping groove 201 is larger than that of the second arc-shaped clamping groove 101, when the upper wire clamp 1 and the lower wire clamp 2 bundle wires, the second arc-shaped clamping groove 101 can move down into the first arc-shaped clamping groove 201, adjusting the distance between the first arc-shaped clamping groove 201 and the second arc-shaped clamping groove 101, so as to clamp circuits of different specifications. At the same time, the serrated anti-slip grooves can better clamp the circuit and prevent the clamped circuit from loosening.

[0043] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
