Description

Technical Field

[0001] This utility model relates to the field of cable supports, and in particular to a lead clamp for power installation. Background Technology

[0002] Multiple power transmission cables require cable supports during installation, and are clamped and fixed to cable clamps on these supports. To accommodate different cable spacings, the position of the cable clamps on the cable supports can be adjusted. Typically, multiple through holes are set side by side on the cable supports. After adjusting the cable clamps to the appropriate position, bolts are used to pass through the through holes to fix the cable clamps. However, to ensure the stability of the fixation, each cable clamp is fixed with at least two bolts, and there are at least three cable clamps on a single cable support. There are also many cable supports on a single column from top to bottom. Therefore, during the entire installation process, the bolts need to be frequently rotated to install all the cable clamps, making the entire operation very cumbersome and greatly reducing installation efficiency. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a wire clamp for power installation, which simplifies the installation steps of cable clamps on cable supports and improves installation efficiency.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] A wire clamp for power installation includes a column, on one side of which multiple cable supports are arranged sequentially from top to bottom. Several n-shaped frames are arranged side by side on the cable supports. The n-shaped frames are slidably connected to the cable supports. A linear adjustment component is installed in the inner cavity of the cable support. The linear adjustment component is used to drive the n-shaped frames to move linearly along the length direction of the cable support. A cable clamp is fixed on the top surface of the n-shaped frames.

[0006] Optionally, the upper ends of the two side walls along the length of the cable bracket are fixed with side sliding strips, and the n-shaped frame includes side connecting plates symmetrically fixed on the outer walls of both sides. The lower ends of the opposite side of the two side connecting plates are fixed with hook strips, and the top surface of the hook strips and the bottom surface of the n-shaped frame form a sliding groove, which cooperates with the side sliding strips.

[0007] Optionally, the end of the side slide bar facing away from the column is at a certain distance from the end of the cable bracket facing away from the column, and the end of the side slide bar does not protrude from the end of the cable bracket. The upper edge of the end of the side slide bar facing away from the column is chamfered.

[0008] Optionally, the linear adjustment assembly includes a screw rotatably installed in the inner cavity of the cable bracket, one end of the screw extending through the cable bracket to the outside of the cable bracket and fixed with a knob, a drive shaft fixed on the top surface of the inner wall of the n-type frame, the drive shaft being inserted into the thread pitch of the screw, and the outer wall of the knob having anti-slip texture.

[0009] Compared with the prior art, the advantages of this utility model are as follows:

[0010] 1. This utility model utilizes a structure consisting of a screw, a drive shaft, and a side slide bar. During cable clamp installation, simply ensure the n-shaped bracket is flush with the cable support and the side slide bar is aligned with the groove. Rotating the screw drives the drive shaft, moving the cable clamp on the cable support to complete the installation. The position of the cable clamp on the cable support can be adjusted by rotating the screw. Once one cable clamp is in the correct position, the next cable clamp is placed, and so on, until all required cable clamps are installed. The entire installation process eliminates the need for frequent bolt tightening, significantly reducing operational steps and improving installation and disassembly efficiency.

[0011] 2. In contrast to the traditional method of opening multiple through holes side by side on the cable bracket to achieve adjustable installation of the cable clamp, the position of the cable clamp in this utility model is not limited to the position of the corresponding through hole, but can be placed at any position on the cable bracket, which greatly improves the adaptability of the entire bracket and can adapt to various cable spacing arrangements.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 4 This embodiment provides a lead wire clamp for power installation, including a column 1. Several cable brackets 2 are fixed at equal intervals from top to bottom on one side of the column 1. Side slides 3 are fixed to the upper ends of both sides of the cable brackets 2. There is a certain distance between the end of the side slide 3 away from the column 1 and the end of the cable bracket 2 away from the column 1. The end of the side slide 3 does not protrude from the end of the cable bracket 2, and the upper edge of the end of the side slide 3 away from the column 1 is chamfered.

[0019] The cable bracket 2 is hollow, with the open end of the inner cavity facing upwards. A screw 4 is rotatably connected to the inner cavity of the cable bracket 2 via a bearing. The length direction of the screw 4 coincides with the length direction of the cable bracket 2. One end of the screw 4 passes through the cable bracket 2 and extends to the side of the cable bracket 2 away from the column 1, where a knob 5 is fixed. The outer wall of the knob 5 has anti-slip textures 6 at equal angle intervals. The column 1 is installed on a wall or utility pole during installation, and its height should meet the cable installation height. The cable bracket 2 has multiple layers, and multiple cables can be installed on each layer.

[0020] Multiple n-shaped frames 7 are mounted side by side on the top of the cable bracket 2. Cable clamps 8 are fixed on the top surface of the n-shaped frames 7. The two ends of the n-shaped frames 7 are respectively mounted on the top surfaces of the two sides along the length of the cable bracket 2. Side connecting plates 9 are symmetrically fixed on the two sides of the n-shaped frames 7 away from the column 1. The n-shaped frames 7 are located between the two side connecting plates 9. Hooks 10 are fixed to the lower ends of the opposite sides of the two side connecting plates 9. A groove 11 is formed between the top surface of the hook 10 and the bottom surface of the n-shaped frame 7, which is just enough to accommodate the side sliding strip 3. A drive shaft 12 is fixed on the top plate of the n-shaped frame 7. The axis of the drive shaft 12 is perpendicular to the axis of the screw 4, and the lower end of the drive shaft 12 is inserted into the thread pitch of the screw 4.

[0021] During installation, the n-type bracket 7 is placed on the top surface of the cable bracket 2, and positioned at the end of the top surface of the cable bracket 2 near the knob 5. This allows the two hook bars 10 to pass under the hook bars 10 from the ends of the side slide bars 3 and the cable bracket 2. Both hook bars 10 are attached to the longitudinal side wall of the cable bracket 2, while the side slide bar 3 is directly opposite the slide groove 11, and the drive shaft 12 is directly opposite the thread pitch of the insertion screw 4. Then, rotating the knob 5 causes the screw 4 to rotate, thereby actuating the drive shaft 12 and pushing the cable bracket. The movable n-shaped frame 7 slides to one side of the column 1, while the side slide bar 3 is inserted into the slide groove 11. The hook bar 10 and the n-shaped frame 7 are locked on the outside of the side slide bar 3. The drive column limits the position of the n-shaped frame 7 in the length direction of the cable bracket 2. The screw 4 does not rotate and the position of the n-shaped frame 7 remains unchanged. By rotating the knob 5, the next n-shaped frame 7 is installed after the n-shaped frame 7 reaches the appropriate position. This continues until all the required n-shaped frames 7 are installed. Then, the cable is fixed in the cable clamp 8 to complete the cable positioning and installation work.

[0022] In summary, during installation, the present invention first fixes the column 1 in the installation position. Then, an n-shaped frame 7 is placed at the end of the cable bracket 2, so that the slide groove 11 is directly opposite the end of the side slide bar 3. Then, the knob 5 is rotated to force the drive shaft 12 and the n-shaped frame 7 to move. The drive screw 4 is rotated until one n-shaped frame 7 reaches the appropriate position. Then, a second n-shaped frame is placed at the end until all n-shaped frames 7 are installed in place. Finally, the cable is passed through the cable clamp 8 and held by the cable clamp 8. Compared with the prior art, the installation process greatly reduces the number of steps for adjusting the position of the cable clamp 8, eliminating the need to rotate multiple bolts and greatly improving installation efficiency. Furthermore, since the cable clamp 8 can be adjusted to any position on the cable bracket 2, the adaptability of the entire fixture is greatly improved.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
