Description

Technical Field

[0001] The utility model relates to the field of cable brackets, in particular to a telescopic cable bracket. Background Art

[0002] In order to standardize the electricity use at the construction site and improve the electricity use safety, cable brackets are often required to install cables at the construction site. A telescopic tunnel cable bracket is disclosed in the Chinese utility model patent with the publication number of CN206742768U. The support structure of the tunnel cable bracket is reasonable and stable, which can bear large-volume and heavy cables, and avoid the disadvantage that the traditional bracket causes the cables to be frequently moved, saving working hours to a certain extent; the upper support arm is self-locked reliably, reducing the cable wear and consumption and improving the construction safety.

[0003] In view of the above related technologies, the inventor believes that there are the following defects: the above-mentioned bracket can only hang one cable. Generally speaking, multiple cables will be set at the construction site. The bracket limits the number of cables that can be hung, and multiple hanging brackets need to be installed, which easily leads to chaos in the construction site installation. In addition, no corresponding support structure is provided on the movable upper support arm, and the strength of the rightmost end is lower when it extends farther. Therefore, we designed a telescopic cable bracket. Summary of the Utility Model

[0004] To solve the technical problems of limited cable hanging quantity and low support strength, the utility model provides a telescopic cable bracket.

[0005] The utility model is realized by adopting the following technical solutions: a telescopic cable bracket includes a fixing plate. A support arm is welded on the right surface of the fixing plate. Two symmetrically distributed support blocks are welded between the support arm and the fixing plate. A telescopic arm is slidably installed on the support arm in the left-right direction. The right end of the lower part of the telescopic arm is rotatably installed with a support rod through a pin. A socket rod is integrally formed at one end of the support rod away from the telescopic arm. The lower part of the right surface of the fixing plate is rotatably installed with a support sleeve through a pin. The lower end of the socket rod is slidably sleeved in the support sleeve. Cable clamping seats are installed above both the telescopic arm and the support arm.

[0006] As a further improvement of the above solution, a plugging cavity is formed by the upper end of the support sleeve being recessed downward. A communication port is formed through the front and rear surfaces of the outer circle of the support sleeve, and the communication port is communicated with the plugging cavity. The socket rod is slidably placed in the plugging cavity. A locking screw is inserted through the front and rear of the bottom end of the socket rod. Nuts are arranged at both the front and rear ends of the locking screw. Circular holes are formed through the front and rear of the socket rod. After the socket rod is inserted into the interior of the plugging cavity, the locking screw is inserted into the circular hole and nuts are screwed on both its front and rear sides, so that it can be fixed, thereby supporting the telescopic arm and improving the support strength.

[0007] As a further improvement of the above solution, a telescopic chute is formed on the left side of the right surface of the support arm, the telescopic arm slides left and right in the telescopic chute, and the cross-sections of the telescopic chute and the telescopic arm are of a convex structure. The upper surface of the support arm is flush with the upper surface of the telescopic arm. The telescopic arm can only slide left and right, and the cable clamping seats installed on the telescopic arm and the support arm are the same, ensuring that the heights of the cables fixed above them are the same.

[0008] As a further improvement of the above solution, a through hole is formed at the bottom of the telescopic chute and penetrates downward. A fixing bolt is threadedly connected to the lower end of the telescopic arm. The head of the fixing bolt is tightly pressed against the lower surface of the support arm. A threaded hole is formed below the telescopic arm. The fixing bolt passes through the through hole from bottom to top and is screwed into the threaded hole. The telescopic arm can be fixed after moving to the required position and can be limited during the movement.

[0009] As a further improvement of the above solution, a compensation notch is formed by removing a part of the right side of the lower surface of the support arm, and the compensation notch communicates with the telescopic chute. After the telescopic arm is completely retracted into the telescopic chute, the support rod can be placed in the position compensation notch without interfering with its normal movement.

[0010] As a further improvement of the above solution, a plurality of equally spaced screw holes I and screw holes II are respectively formed on the upper surfaces of the support arm and the telescopic arm. A threaded rod is provided at the bottom end of the cable clamping seat. The cable clamping seat is threadedly connected in the screw holes I and screw holes II through the threaded rod. The appropriate number of cable clamping seats can be installed at the appropriate positions according to needs. Each cable clamping seat corresponds to a cable of a certain size. The cable clamping seats have a variety of different sizes, they are applicable to a variety of different sizes of cables, and their installation methods are the same.

[0011] As a further improvement of the above solution, the bottom end of the cable clamping seat is thickened to form a horizontal part. The design of the horizontal part enables the bottom end of the cable clamping seat to be in full contact with the upper surfaces of the support arm and the telescopic arm, improving the connection firmness. A part of the right side of the cable clamping seat is removed to form an opening, and the upper and lower ends of the opening are bent outward to form arc-shaped parts. The design of the arc-shaped parts makes the outer dimension of the opening larger and its inner dimension smaller. It is convenient for the cable to be clamped into the cable clamping seat through the opening without scratching the outer surface of the cable.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, a telescopic arm that slides left and right is provided on the support arm. Multiple cable clamping seats can be installed on their upper surfaces according to needs. Multiple cables can be installed and laid according to the actual situation, and the positions of the cables can be adjusted;

[0014] By arranging a socket rod and a support sleeve under the telescopic arm, the length between the two can be adjusted as needed. It can move along with the telescopic arm and effectively support the lower part of the telescopic arm, improving its connection strength. Description of the Drawings
