DETAILED DESCRIPTION

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] It should be noted that all components in the technical solution of this application require the necessary additional facilities of water supply, oil supply, electricity supply and gas supply to be driven and / or controlled. If there is no further explanation, it is assumed that the existing technology is used and equipped without special explanation.

[0023] It should be noted that, in order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Depend on Figure 1-2A cable clip that is easy to disassemble as shown includes a number of clamping heads. Each clamping head includes a fixing rod 1. At the top end of the fixing rod 1, a driving head 2 is fixedly connected. A sleeve column 4 is sleeved outside the driving head 2. A threaded groove is provided on the outer side surface of the sleeve column 4, and the threaded groove is clamped with a cable 5. At the top and bottom ends of the sleeve column 4, a first top block 6 and a second top block 7 are respectively provided. A number of screw rods 8 penetrate through and are screwed to the bottom end of the second top block 7. The top ends of the screw rods 8 respectively penetrate through the sleeve column 4 and the first top block 6 and are screwed with nuts 9. There is a gap between the nut 9 and the top surface of the first top block 6, which facilitates the first top block 6 and the second top block 7 to be driven to lift through the side pushing assembly. A number of fixing strips 10 are fixedly connected between the side surface of the first top block 6 and the side surface of the second top block 7 by screws. The fixing strips 10 are elastic steel plates or resin plates, and the middle part thereof is an arc-shaped structure, which is convenient for cooperating with the threaded groove to clamp the cable 5 and can also realize the extrusion of the cable 5 through the expansion and contraction of both ends. The fixing strips 10 are detachably connected to the cable 5. A number of side pushing assemblies are respectively provided on the bottom surface of the first top block 6 and the top surface of the second top block 7. The side pushing assemblies are detachably connected to the driving head 2. The bottom end of the fixing rod 1 is fixedly connected with a cross beam 19. The cross beam 19 is fixedly connected to the erection truss of the cable 5, which is an existing technology and will not be elaborated here.

[0025] Further, the cable 5 is sleeved on the threaded groove, and there is a gap between the upper and lower layers of the cable 5 to prevent the cables 5 from rubbing against each other and causing wear.

[0026] In a further optimized solution, the driving head 2 is of a spindle-shaped structure, which can drive the side pushing assemblies on one side of the first top block 6 and the second top block 7. The sleeve column 4 is made of flexible rubber or polyurethane material; a sliding hole 11 is provided in the middle of the sleeve column 4, and the sliding hole 11 is adapted to the driving head 2.

[0027] In a further optimized solution, a wear-resistant sleeve 12 is sleeved on the outer side surface of the sleeve column 4. The wear-resistant sleeve 12 is made of polyurethane resin or polystyrene resin or polyethylene resin or epoxy resin; the side surface of the wear-resistant sleeve 12 is adapted to the side surface of the sleeve column 4 and is clamped with the cable 5. The wear-resistant sleeve 12 is arranged between the sleeve column 4 and the cable 5 to protect the sleeve column 4 from excessive wear.

[0028] In a further optimized solution, as Figure 3 shown, a number of first sliding grooves 13 and a number of second sliding grooves 14 are respectively provided on the bottom surface of the first top block 6 and the top surface of the second top block 7. The first sliding grooves 13 are communicated with the second sliding grooves 14. The side pushing assembly includes a wedge block 15. One end of the wedge block 15 is detachably connected to the side surface of the driving head 2. The wedge block 15 is adapted to and slidably connected with the first sliding groove 13. The bottom surface of the wedge block 15 is in sliding contact with the top surface or the bottom surface of the sleeve column 4 (specifically depending on whether the wedge block 15 is above or below the sleeve column 4). A push plate 16 is fixedly connected to the top surface of the wedge block 15. The push plate 16 is arranged in the second sliding groove 14, and a first spring 17 is fixedly connected between the push plate 16 and one end surface of the second sliding groove 14.

[0029] In a further optimized solution, relief holes 18 for facilitating the movement of the driving head 2 are respectively formed on the top surfaces of the first top block 6 and the second top block 7.

[0030] In a further optimized solution, a second spring 3 is sleeved on the outer side surface of the fixed rod 1. The top end and the bottom end of the second spring 3 are respectively fixedly connected to the second top block 7 and the cross beam 19, which can balance the weight of a certain amount of the cable 5 and reduce the pressure on the cross beam 19.

[0031] The working process of this embodiment is as follows:

[0032] In this utility model, the cable 5 is sleeved on the outer side surface of the sleeve column 4 along the thread groove, and the wear-resistant sleeve 12 adapted to the sleeve column 4 is used for separation to prevent the swaying cable 5 from excessively wearing the sleeve column 4, resulting in the failure of this utility model.

[0033] After the cable 5 is sleeved on the sleeve column 4, the cables 5 on both sides of the sleeve column 4 will press the sleeve column 4 downward by a certain distance due to their own weight. After the sleeve column 4 moves downward, the sliding hole 11 in the middle of the sleeve column 4 will slide along the driving head 2. Furthermore, the driving head 2 will expand the top end of the sliding hole 11, thereby expanding the diameter of the top end of the sleeve column 4, realizing the extrusion of the surrounding cable 5. And when the cable 5 sways, the second spring 3 can reduce the pressure on the cross beam 19 by offsetting a part of the force.

[0034] When the cable 5 on one side of the sleeve column 4 breaks, the pressure on the second spring 3 decreases, and the second spring 3 rebounds, jacking up the sleeve column 4 by a certain distance. At this time, the driving head 2 starts to drive a plurality of wedge blocks 15 on the top surface of the second top block 7. The wedge blocks 15 move towards the fixed strip 10 to drive the sleeve column 4 to move upward, thereby increasing the distance between the first top block 6 and the second top block 7, so that the length of the fixed strip 10 increases. The increase in the length of the fixed strip 10 causes the middle arc thereof to push towards the cable 5, thereby firmly fixing the cable 5 on the sleeve column 4 and reducing the harm of the broken end of the cable 5 to the environment.

[0035] The above is only the preferred specific embodiment of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in this application should be covered by the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
