[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: during use of the existing cable pulley, since the cable needs to be placed inside the pulley, and the existing cable pulley cannot quickly disassemble and close the bracket, the cable cannot be conveniently placed inside the pulley, reducing the convenience of the cable pulley. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the prior art has the disadvantage that the bracket cannot be quickly disassembled and closed, so we propose a rolling cable pulley.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a rolling cable pulley, comprising a first bracket, the right end of the first bracket is rotatably connected to the second bracket through a hinge, the top ends of the first bracket and the second bracket are fixedly connected to a support column, the surface of the support column is fixedly connected to an arc block, the front end of the first bracket is installed with a hollow block, the interior of the hollow block is rotatably connected to a threaded rod, the top end of the threaded rod is fixedly connected to a knob, and the surface of the threaded rod is threadedly connected to a threaded block.

[0007] Preferably, notches are provided on both sides of the hollow block, and a sliding rod is slidably connected to the inner diameter of the notch, and one end of the sliding rod close to the threaded block is fixedly connected to the threaded block.

[0008] Preferably, the top ends of the first bracket and the second bracket are both provided with a circular groove, the inner diameter of the circular groove is slidably connected to a limiting column, and the bottom end of the limiting column is fixedly connected to the sliding rod.

[0009] Preferably, the arc block is internally slidably connected to a connecting oblique block, the rear end of the connecting oblique block is fixedly connected to a fixed plate, the rear end of the fixed plate is fixedly connected to a fixed block, the interior of the fixed block is fixedly connected to a separate main shaft, and the surface of the separate main shaft is rotatably connected to a separate roller.

[0010] Preferably, a slide groove is provided inside the arc block, and a slider is slidably connected to the inner diameter of the slide groove, and one end of the slider close to the connecting oblique block is fixedly connected to the connecting oblique block.

[0011] Preferably, a pressure spring is fixedly connected to the inner cavity of the arc block, and a rear end of the pressure spring is fixedly connected to the connecting oblique block.

[0012] Technical effects and advantages of the utility model:

[0013] In the utility model, a worker turns the knob to rotate the threaded rod, thereby driving the threaded block to move horizontally downward in the hollow block, and at the same time driving the limit column to move, so that the limit column gradually separates from the inner diameter of the circular groove. Through the arrangement of the above-mentioned structure, it is convenient for the worker to quickly disassemble and open the first bracket and the second bracket, so that the worker can quickly put in the cable, thereby improving the convenience of the cable pulley.

[0014] In the utility model, after the staff puts the cable in, due to the different lengths, thicknesses and thicknesses of the cables, the rebound force of the pressure spring continuously pushes the connecting bevel block to move outward, and at the same time pushes the fixed plate and the fixed block to move outward, so that the rolling surface of the separate roller fits the cable more closely. Through the arrangement of the above structure, the cable pulley is suitable for cables of different sizes, thereby improving the overall applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 3 As shown, the utility model provides a technical solution: a rolling cable pulley comprises a first bracket 1, the right end of the first bracket 1 is rotatably connected to the second bracket 2 by a hinge, the tops of the first bracket 1 and the second bracket 2 are fixedly connected to the supporting column 3, the surface of the supporting column 3 is fixedly connected to the arc block 4, the front end of the first bracket 1 is installed with a hollow block 5, the interior of the hollow block 5 is rotatably connected to a threaded rod 6, the top of the threaded rod 6 is fixedly connected to a knob 7, and the surface of the threaded rod 6 is threadedly connected to a threaded block 8. When the staff needs to put in the cable, the staff turns the knob 7 to rotate the threaded rod 6, and at the same time drives the surface of the threaded block 8 to move horizontally downward in the inner cavity of the hollow block 5, and at the same time drives the limiting column 12 to displace, so that the surface of the limiting column 12 gradually separates from the inner diameter of the circular groove 11. Through the arrangement of the above structure, it is convenient for the staff to quickly disassemble and open the first bracket 1 and the second bracket 2, so that it is convenient for the staff to quickly put in the cable, thereby improving the convenience of the cable pulley.

[0023] Reference Figure 3 As shown, in this embodiment: slots 9 are provided on both sides of the hollow block 5, and the inner diameter of the slot 9 is slidably connected with a slide rod 10, and the end of the slide rod 10 close to the threaded block 8 is fixedly connected to the threaded block 8. With the horizontal displacement of the threaded block 8, the threaded block 8 drives the surface of the slide rod 10 to slide in the inner diameter of the slot 9. Through the setting of the above structure, the threaded block 8 is prevented from rotating with the threaded rod 6 during the movement.

[0024] Reference Figure 3 As shown, in this embodiment: a circular groove 11 is provided at the top of the first bracket 1 and the second bracket 2, the inner diameter of the circular groove 11 is slidably connected to a limiting column 12, and the bottom end of the limiting column 12 is fixedly connected to the sliding rod 10. As the sliding rod 10 moves, the sliding rod 10 drives the surface of the limiting column 12 to gradually separate from the inner diameter of the circular groove 11. At this time, the first bracket 1 and the second bracket 2 will not be constrained by the circular groove 11 and can be opened.

[0025] Reference Figure 1 , Figure 4 and Figure 5As shown, in the present embodiment: the arc block 4 is internally slidably connected with a connecting bevel block 13, the rear end of the connecting bevel block 13 is fixedly connected with a fixing plate 14, the rear end of the fixing plate 14 is fixedly connected with a fixing block 15, the interior of the fixing block 15 is fixedly connected with a separate main shaft 16, the surface of the separate main shaft 16 is rotatably connected with a separate roller 17, when the staff puts the cable in, due to the different lengths and thicknesses of the cables, the rebound force of the pressure spring 20 continuously pushes the connecting bevel block 13 to move outward, and at the same time pushes the fixing plate 14 and the fixing block 15 to move outward, so that the rolling surface of the separate roller 17 is more closely fitted to the cable, through the arrangement of the above structure, the cable pulley is suitable for cables of different sizes, so that the overall applicability is improved.

[0026] Reference Figure 5 As shown, in this embodiment: a slide groove 18 is opened inside the arc block 4, and a slider 19 is slidably connected to the inner diameter of the slide groove 18, and the end of the slider 19 close to the connecting bevel block 13 is fixedly connected to the connecting bevel block 13. As the rebound force of the pressure spring 20 continues to push the connecting bevel block 13 to move outward, the connection bevel block 13 remains stable and does not shake during the movement through the setting of structures such as the slide groove 18 and the slider 19.

[0027] Reference Figure 5 As shown, in this embodiment: the inner cavity of the arc block 4 is fixedly connected with a pressure spring 20, and the rear end of the pressure spring 20 is fixedly connected to the connecting bevel block 13. Through the setting of the pressure spring 20, the rebound force of the pressure spring 20 continuously pushes the connecting bevel block 13 to move outward, and at the same time drives the rolling surface of the separate roller 17 to fit more closely to the cable surface.

[0028] The practical working principle of the present invention is as follows: when the staff needs to put in the cable, the staff turns the knob 7 to rotate the threaded rod 6, and at the same time drives the surface of the threaded block 8 to move horizontally downward in the inner cavity of the hollow block 5, and at the same time drives the limit column 12 to move, so that the surface of the limit column 12 gradually separates from the inner diameter of the circular groove 11. Through the setting of the above structure, it is convenient for the staff to quickly disassemble and open the first bracket 1 and the second bracket 2, so that the staff can quickly put in the cable, which improves the convenience of the cable pulley. When the staff puts in the cable, due to the different lengths and thicknesses of the cables, the rebound force of the pressure spring 20 continuously pushes the connecting inclined block 13 to move outward, and at the same time pushes the fixed plate 14 and the fixed block 15 to move outward, so that the rolling surface of the separate roller 17 is more in line with the cable. Through the setting of the above structure, the cable pulley is suitable for cables of different sizes, so that the overall applicability is improved.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
