[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This cable laying bending protection structure, through the inclusion of a first fixing ring seat, a second fixing ring seat, a tightening cover, a threaded seat, a rotating rubber ring, a sealing ring, a tightening ring cover, a tightening ring, a threaded groove, a top connecting ring, a shrinkage airbag, and a shrinkage top strip, allows the equipment to perform more secure protection operations at cable laying bending points. In actual use, the operator first adjusts the first and second fixing ring seats according to the bending angle, then inserts the cable through the first fixing ring seat, along the protective cover, and exits through the second fixing ring seat. At this point, the first and second fixing ring seats can be securely connected. Tightening the cap at one end of the two fixed ring seats causes the threaded seat of the cap to be tightened in accordance with the threaded groove of the first fixed ring seat. This tightening compresses the top ring and the shrinking airbag into the first and second fixed ring seats, causing the shrinking airbag to contract. This causes the shrinking top bars on the four sides of the inner walls of the first and second fixed ring seats to be pushed towards the center, thus quickly and firmly pushing the side of the cable inserted into the first and second fixed ring seats. This provides a firm limit on the bending ends of the cable, offering reliable bending protection and demonstrating the practicality of the equipment design.

[0015] This cable laying bend protection structure, through the inclusion of a first fixing ring, a second fixing ring, a protective cover, a limiting rubber strip, a movable curtain, a sealing strip, and a detection groove, further enhances the overall effectiveness of the equipment. During daily use, when the cable bends along the protective cover, the protective cover, in conjunction with the movable curtain and sealing strip at the center of the limiting rubber strip, provides proper protection at the cable bend. Subsequent maintenance and inspection of the cable bend can be performed by simply opening the movable curtain and sealing strip, and then directly inspecting the internal cable bend through the detection groove between the protective cover and the limiting rubber strip, without requiring complete disassembly and assembly, demonstrating the comprehensiveness of the equipment design.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 One embodiment provided by this utility model:

[0023] A protective structure for cable laying bends includes a first fixing ring seat 1 and a second fixing ring seat 2. The first fixing ring seat 1 and the second fixing ring seat 2 have the same structure. A tightening cover 3 is movably connected to one end of the first fixing ring seat 1 and the second fixing ring seat 2. A threaded seat 4 is fixedly connected to the back of the tightening cover 3. A threaded groove 14 is formed on one end of the inner wall of the first fixing ring seat 1. A top connecting ring 15 is movably connected inside the first fixing ring seat 1. A contraction airbag 16 is provided on the back of the top connecting ring 15. The four sides of the wall are provided with shrinking top strips 17 through the shrinking airbag 16. The tightening cover 3 at one end of the first fixing ring seat 1 and the second fixing ring seat 2 can be turned. The threaded seat 4 of the tightening cover 3 is turned in a matching way at the threaded groove 14 of the first fixing ring seat 1, and the top connecting ring 15 and the shrinking airbag 16 are squeezed into the interior of the first fixing ring seat 1 and the second fixing ring seat 2, so that the shrinking airbag 16 shrinks and the shrinking top strips 17 on the four sides of the inner wall of the first fixing ring seat 1 and the second fixing ring seat 2 are pushed towards the center.

[0024] A protective cover 5 is provided between the first fixing ring seat 1 and the second fixing ring seat 2. The inner wall of the protective cover 5 is provided with a limiting rubber strip 6. A movable curtain 7 is provided between the upper and lower limiting rubber strips 6. A sealing rubber strip 8 is provided between the two sets of movable curtains 7. A detection groove 9 is opened between the upper and lower limiting rubber strips 6. A rotating rubber ring 10 is provided at one end of the threaded seat 4. A sealing ring 11 is provided at one end of the tightening cover 3. A tightening ring cover 12 is provided on the inner wall of the tightening cover 3. A tightening ring 13 is provided on the inner wall of the tightening ring cover 12. When the cable is protected at the bending part along the protective cover 5, the protective cover 5, together with the movable curtain 7 and the sealing rubber strip 8 in the center of the limiting rubber strip 6, can properly cover and protect the cable bending position. When the cable bending position needs to be maintained and inspected later, the movable curtain 7 and the sealing rubber strip 8 can be directly opened.

[0025] Working principle: In use, the user first fixes the first fixing ring seat 1 and the second fixing ring seat 2 according to the bending angle. Then, the cable is inserted from the first fixing ring seat 1, passes through the protective cover 5, and exits from the second fixing ring seat 2. At this time, the tightening cap 3 at one end of the first fixing ring seat 1 and the second fixing ring seat 2 can be turned. The threaded seat 4 of the tightening cap 3 is turned in accordance with the threaded groove 14 of the first fixing ring seat 1, and the top connecting ring 15 and the shrinking air bag 16 are squeezed into the inside of the first fixing ring seat 1 and the second fixing ring seat 2, thereby causing the shrinking air bag 16 to contract. This causes the shrinking top strips 17 on the four sides of the inner wall of the first fixing ring seat 1 and the second fixing ring seat 2 to push towards the center, thereby quickly connecting the cable to the first fixing ring seat 1. The cable sides inside the fixing ring seat 1 and the second fixing ring seat 2 are firmly connected to each other, providing a firm limit at both ends of the cable bend and providing reliable bending protection for the cable. During daily use, when the cable bends along the protective cover 5, the protective cover 5, together with the movable curtain 7 and sealing strip 8 in the center of the limiting rubber strip 6, can properly cover and protect the cable bending position. When the cable bending position needs to be maintained and inspected later, the movable curtain 7 and sealing strip 8 can be directly opened, and the internal cable bending position can be inspected directly from the inspection groove 9 between the protective cover 5 and the limiting rubber strip 6 without the need for overall disassembly and assembly. The above is the complete working principle of this utility model.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
