At the same time, cables also have the function of power distribution. Moreover, when working, cables are also reliable and efficient. Cables can be installed in multiple locations such as buildings and tunnels.

[0003] When cables are to be pre-buried in a tunnel, cable installation brackets need to be set up in advance. During the installation process, workers need to carry a large number of disassembly and assembly tools to disassemble and assemble the brackets, which slows down the operation process and reduces work efficiency.

[0004] In order to overcome the above-mentioned defects, prior art 1 (Chinese patent application number CN201810080063.0, application date 2018-01-27) is a combined cable bracket, which has the advantages of being detachable, easy to transport and having a wide range of uses;

[0005] Prior art 2 (Chinese patent application number CN201710866927.7, application date September 22, 2017) is a cable bracket fixing structure that can conveniently fix, install, and remove the cable bracket and its connected parts, and has accurate installation positioning and reliable fixing, thereby reducing the labor intensity of the operator;

[0006] However, during long-term use, the support arm may adhere to the mainboard, and the device in the above application does not have the function of assisting disassembly when in use. Therefore, when the support arm needs to be removed, there is great resistance, which increases the difficulty of disassembly.

[0007] In view of the above problems, it is urgent to carry out innovative design based on the original cable installation bracket. Utility Model Content

[0008] The purpose of the present utility model is to provide a pre-buried tunnel cable installation bracket to solve the problem proposed in the above background technology that it has no auxiliary disassembly function during use, and further when the support arm needs to be removed, there is large resistance, which increases the difficulty of disassembly.

[0009] To achieve the above-mentioned object, the present invention provides the following technical solution: a pre-buried tunnel cable installation bracket, comprising a main board, the surface of which is concave, and a connecting plate is snap-connected to the inside of the main board, and the end of the connecting plate is fixedly connected to the frame;

[0010] A pre-buried tunnel cable installation bracket further comprising:

[0011] a card block, the card block being slidably disposed inside the connecting plate and symmetrically distributed about the center of the connecting plate;

[0012] A traction chain is slidably arranged inside the connecting plate, and one side of the traction chain is fixedly connected to the surface of the clamping block.

[0013] Preferably, a card slot is provided on the surface of the mainboard, and the card slot corresponds to the card block one by one.

[0014] Preferably, a deep groove is provided on the surface of the connecting plate, and the surface of the clamping block fits with the inner wall of the deep groove.

[0015] Preferably, a reset spring that performs elastic reset is fixedly connected to the surface of the block, and the other side of the reset spring is fixedly connected to the inner wall of the connecting plate. The end of the traction chain is located on the outside of the connecting plate, and the end of the traction chain is fixedly connected to a handle.

[0016] Preferably, positioning rods are fixedly connected to the surface of the connecting plate, and the positioning rods are symmetrically distributed about the center of the connecting plate, and positioning grooves corresponding to the positioning rods are opened inside the main board.

[0017] Preferably, a first magnet is fixedly connected to the end of the connecting plate, and a second magnet is embedded in the interior of the main board.

[0018] Preferably, the connecting plates are distributed at equal intervals on the inner wall of the main board, the first magnets and the second magnets correspond one to one, and the magnetic poles at the ends of the first magnets are the same as the magnetic poles at the ends of the second magnets.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the pre-buried tunnel cable installation bracket adopts a new structural design, the specific contents of which are as follows:

[0020] (1) When the pre-buried tunnel cable installation bracket is connected to the frame, the connecting plate is inserted into the main board. At this time, the card block will be squeezed by the inner wall of the main board, and then the card block moves in the direction of the extrusion reset spring. When the card block and the card slot are in the same horizontal direction, the card block enters the inside of the card slot under the action of the reset spring, that is, the frame has been connected to the main board. The operation process is fast and convenient. After that, the remaining frames and connecting plates can be connected through the same operation. The work efficiency is high and the staff does not need to carry a large number of disassembly and assembly tools, which facilitates the work of the staff.

[0021] Furthermore, in the process of docking the connecting plate and the frame, the positioning rod and the positioning slot play an auxiliary positioning role, which is convenient for the workers to quickly put the card block and the card slot in the same horizontal direction during installation, thereby improving work efficiency;

[0022] (2) When the pre-buried tunnel cable installation bracket needs to disassemble the connecting plate and the frame, the staff can pull the handle, and the handle drives the clamping block to move to the inner position of the deep groove through the traction chain. After the end of the clamping block moves out of the slot, the connecting plate and the main board are no longer in the engaged state, and the staff can then remove the connecting plate;

[0023] Furthermore, the ends of the traction rope are connected to the clamping blocks on both sides at the same time, that is, the staff can release the clamping state of the left and right sides at the same time through the handle, which improves the work efficiency;

[0024] (3) When the pre-buried tunnel cable installation bracket is docked with the connecting plate, the first magnet will be close to the second magnet, that is, the connecting plate is always subjected to the repulsive magnetic force when it is working. When the staff disassembles the connecting plate, when the connecting plate and the main board are not in a locked state, the connecting plate will tend to move outward under the action of the repulsive magnetic force, that is, the first magnet and the second magnet play the role of auxiliary disassembly, which makes it easier for the staff to disassemble the connecting plate and the frame.
