In order to solve the problem that the existing cable protection tubes have poor splicing effect during installation and cannot be accurately combined according to the pre-buried needs, which is not conducive to the subsequent cable installation, the first support plate and the second support plate are cooperated to support and fix one or more cable protection tubes according to the pre-buried needs to ensure the subsequent cable installation. However, if the above technical solution encounters a large number of cable requirements, the first support plate and the second support plate need to be threaded and assembled one by one. The installation steps are relatively cumbersome, and after the assembly is completed, the cable space in the arc-shaped placement port is limited. When the cables are of different thicknesses, the fixing effect is not ideal. Therefore, the applicant proposes a support structure for pre-buried cable protection tubes. Utility Model Content

[0031] like Figures 1 to 4 As shown, an embodiment of the present invention provides a support structure for pre-buried cable protective tubes, including a fixed block 1, a plug rod protruding from the bottom of the fixed block 1, and a pointed angle setting at the bottom of the plug rod; a slide groove 2 is vertically provided on the outer wall on one side of the fixed block 1, and a slider 5 is fixedly installed on the outer wall on the other side opposite to the slide groove 2, and the slider 5 is a protruding structure and is slidably adapted to the slide groove 2; an elastic clip is protruding from the outer wall of the slider 5, and a limiting hole 6 is provided through the fixed block 1 corresponding to the slide groove 2, and the elastic clip is adapted to be engaged with the limiting hole 6.

[0032] like Figure 1-Figure 3As shown, the fixed block 1 has a cable threading hole 3 in the center, and a clamping block 4 is elastically mounted on the inner wall of the cable threading hole 3. The clamping blocks 4 are distributed around the inner wall of the cable threading hole 3. An adjusting head 14 is mounted on the upper surface of the fixed block 1, and the adjusting head 14 is arranged to rotate horizontally. A rotating shaft 16 is fixedly connected to the center of the bottom circle of the adjusting head 14, and a driving screw 9 is fixedly connected to the end of the rotating shaft 16 away from the adjusting head 14. A rotating hole 15 is formed through the fixed block 1 for the rotating shaft 16 to pass through, and the rotating shaft 16 is rotatably mounted in the rotating hole 15. The driving screw 9 is vertically arranged inside the fixed block 1, and the bottom is rotatably connected to the inner wall of the bottom end of the fixed block 1. A moving block 11 is threadedly mounted on the outer wall of the driving screw 9, and the moving block 11 is in contact with the inner wall of the fixed block 1. The end of the moving block 11 away from the inner wall of the fixed block 1 is fixedly connected to the driving block 13, and the end of the driving block 13 away from the moving block 11 is arranged in an arc shape. The end of the clamping block 4 penetrates into the interior of the fixing block 1 and is fixedly connected to the fixing ring 10. The return spring 12 is sleeved on the outside of the clamping block 4, one end of the return spring 12 is connected to the fixing ring 10, and the other end of the return spring 12 is fixedly connected to the inner wall of the fixing block 1.

[0033] The working principle of the technical solution provided by this utility model is as follows:

[0034] When in use, first combine the fixing blocks 1 according to the number of cable arrangements required, fit the slider 5 on the side wall of the fixing block 1 into the slide groove 2 on the side wall of the other fixing block 1, and move the slider 5 vertically downward along the slide groove 2 until the elastic buckle corresponds to the limiting hole 6. The elastic buckle pops out directly, thereby forming a fixing force between the fixing blocks 1, making the assembly convenient.

[0035] Then the cable is installed, the cable is passed through the cable threading hole 3, and then the adjusting head 14 is rotated. The adjusting head 14 drives the driving screw 9 to rotate through the rotating shaft 16. The upper thread and the lower thread of the outer wall of the driving screw 9 are oppositely set. Therefore, when the driving screw 9 rotates, the two moving blocks 11 installed with the external threads move closer to each other, and the moving block 11 drives the driving block 13 to move synchronously. The driving block 13 squeezes the fixing ring 10, and then the clamping block 4 is forced to move toward the inside of the cable threading hole 3. At this time, the spring is compressed until the clamping block 4 fits against the outer wall of the cable. The cable is clamped in four directions in the cable threading hole 3, which can effectively improve the clamping force of the cable and clamp cables of different thicknesses at the same time. It has a wide range of applications and a good clamping effect.

[0036] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
