Description

Technical Field

[0001] This utility model relates to the field of cable technology, and specifically to a cable mounting bracket. Background Technology

[0002] A cable is an electrical or signal transmission device, typically composed of several or more conductors, and characterized by internal current conduction and external insulation. Cables can be used to transmit electrical (magnetic) energy and information, realizing the conversion of electromagnetic energy. They are widely used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater power transmission lines across rivers and seas. There are many types of cables, including power cables, control cables, compensating cables, shielded cables, and high-temperature cables, which consist of single or multiple conductors and insulation layers, used to connect circuits and electrical appliances.

[0003] For example, Chinese utility model patent CN210326962U discloses a cable installation and fixing bracket for tunnels, including a tunnel and a support frame. Several support frames are evenly and symmetrically distributed on both sides of the tunnel. Installation components are fixedly connected to the upper and lower end faces of the support frames, and these components are bolted to the side walls of the tunnel. An installation frame body is vertically fixed to the end of the support frame. Several bases are evenly distributed on the outer wall side of the installation frame body away from the support frame. The upper end face of each base has a fixing groove for placing cables. A clamping component is provided on one side of the fixing groove, and an annular limiting block is provided on the inner wall of the clamping component. A reciprocating screw is horizontally provided on the side wall of the annular limiting block, extending outward through the side wall of the base. A limiting movable support rod is symmetrically provided on the outer wall of the clamping component and on both sides of the reciprocating screw, extending towards the side wall of the base. The side wall of the base has a movable groove corresponding to the limiting movable support rod, and a spring is sleeved on the outer wall of the limiting movable support rod. Although this utility model can achieve the beneficial effects of supporting and fixing the cable, making it less likely to fall off and allowing for flexible positioning of the cable, it also has certain drawbacks: the clamping component and the fixing groove in this utility model are not suitable for clamping cables of different diameters, and the inner wall shape of the fixing groove is different from the cable shape, which can easily cause local compression of the cable during the clamping process, affecting the cable's service life. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a cable installation fixing bracket that can solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cable mounting bracket includes a base plate, with lead screws at both ends of the top surface of the base plate. A threaded cylinder is threadedly connected to the outer side of each lead screw, and the threaded cylinder is fixedly connected to the bottom of a movable plate. A top plate is connected to the upper end of each lead screw, and a power mechanism is located on the top of the top plate. An upper clamping block is located at the bottom of the top plate, and a lower clamping block is located on the top of the movable plate. Both the upper and lower clamping blocks have steps of different curvatures. The steps on the upper and lower clamping blocks cooperate to clamp cables of different diameters.

[0007] Preferably, the curvature of the upper and lower clamping blocks and the steps gradually increases from one end to the other.

[0008] Preferably, the upper and lower ends of the lead screw are connected to the top plate and the bottom plate through bearings, and the upper end of the lead screw passes through the top plate and is connected to the power mechanism.

[0009] Preferably, the power mechanism includes a motor, a rotating shaft is connected to the output shaft of the motor, a bevel gear one is connected to the rotating shaft, the bevel gear one meshes with a bevel gear two, and the bevel gear two is fixed to the top of the lead screw.

[0010] Preferably, a support column is provided between the top plate and the bottom plate, and the support column penetrates the movable plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses an upper clamping block and a lower clamping block to clamp and fix the cable end. The multiple steps with different curvatures on the upper and lower clamping blocks are conducive to clamping cables of different diameters, while avoiding local compression of the cable, making it highly practical.

[0013] 2. This utility model uses a power mechanism to drive the lead screw to rotate. The lead screw is threadedly connected to the threaded cylinder, which is fixedly connected to the bottom of the movable plate. This allows the movable plate to move up and down, which facilitates the upper and lower clamping blocks to cooperate and clamp the cable. Attached Figure Description

[0019] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Example

[0020] like Figures 1 to 2 As shown, this utility model discloses a cable installation fixing bracket, including a base plate 1. Both ends of the top surface of the base plate 1 are provided with lead screws 2. A threaded cylinder 3 is threadedly connected to the outer side of each lead screw 2, and the threaded cylinder 3 is fixedly connected to the bottom of a movable plate 4. A top plate 5 is connected to the upper end of each lead screw 2. A support column 14 is provided between the top plate 5 and the base plate 1, and the support column 14 penetrates the movable plate 4. The upper and lower ends of the lead screw 2 are connected to the top plate 5 and the base plate 1 via bearings 9. The upper end of the lead screw 2, after penetrating the top plate 5, is connected to a power mechanism.

[0021] The top plate 5 is equipped with a power mechanism, which includes a motor 10. A rotating shaft 11 is connected to the output shaft of the motor 10, and a bevel gear 12 is connected to the rotating shaft 11. The bevel gear 12 meshes with a bevel gear 13, which is fixed to the top of the lead screw 2. The motor 10 drives the rotating shaft 11 to rotate, which in turn drives the bevel gear 12 to rotate the bevel gear 13, thereby realizing the up-and-down movement of the movable plate 4, which facilitates the upper clamping block 6 and the lower clamping block 7 to clamp the cable.

[0022] Furthermore, in this embodiment, the top plate 5 is provided with an upper clamping block 6 at its bottom and the movable plate 4 is provided with a lower clamping block 7 at its top. Both the upper clamping block 6 and the lower clamping block 7 are provided with steps 8 of different curvatures. The curvature of the steps 8 on the upper clamping block 6 and the lower clamping block 7 gradually increases from one end to the other end. The steps 8 on the upper clamping block 6 and the steps 8 on the lower clamping block 7 cooperate to clamp the ends of cables of different diameters.

[0023] Working principle: In use, the upper clamping block 6 and the lower clamping block 7 separate. The cable end is placed on the appropriate step 8 on the lower clamping block 7. The motor 10 drives the lead screw 2 to rotate, which in turn moves the movable plate 4 upward until the lower clamping block 7 on the movable plate 4 engages with the upper clamping block 6 on the top plate 5 to clamp the cable. At this point, the motor 10 stops. By setting the upper clamping block 6 and the lower clamping block 7 to clamp and fix the cable end, the cable is less likely to fall off. At the same time, the shape of the step 8 on the upper clamping block 6 and the lower clamping block 7 conforms to the shape of the cable, preventing compression of the cable and extending the cable's service life.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and application concept of the present utility model, should be included within the protection scope of the present utility model.
