Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a bend-resistant cable. Background Technology

[0002] A cable is an electronic device used to transmit electrical energy, data, or signals. It typically consists of multiple conductors or optical fibers and is protected by a sheath. In practical engineering, cable laying paths often need to bypass obstacles such as buildings, equipment, and pipes, thus requiring bends at turns. For example, cables may be laid in complex paths such as tunnels, trenches, and under supports.

[0003] In existing technologies, the bending process of cables relies entirely on their own rigidity and external laying tension to maintain their shape, making it difficult to control the bending angle and radius. Especially at large angles, the outer side of the cable is prone to excessive stretching, while the inner side is subjected to excessive compression, resulting in uneven stress on the conductor, insulation layer, and sheath of the cable. Therefore, we propose a bend-resistant cable to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bend-resistant cable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bend-resistant cable includes an open sheath, with two semi-circular sleeves fixedly connected to each end of the open sheath. The four semi-circular sleeves are hinged together in pairs. The cable body is placed inside the open sheath. Ear plates are fixedly connected to the outer walls of the four semi-circular sleeves. Through holes are formed on the outer walls of the four ear plates. Bolts are slidably connected to the four through holes in pairs. Ball sleeves are fixedly connected to the outer walls of the two semi-circular sleeves. A ball is rotatably connected inside the two ball sleeves. A concave hole is formed on the outer wall of the two ball sleeves. A support component is provided on the outer wall of the ball.

[0007] Preferably, the support assembly includes two sleeves, the outer walls of the two spheres are fixedly connected to one end of the two sleeves respectively, the inner walls of the two sleeves are threaded with threaded rods, and one end of the two threaded rods is fixedly connected with a pad. The support assembly supports the support bar and the four semi-circular sleeves.

[0008] Preferably, a support bar is fixedly connected to the outer wall of the open rubber sleeve, and an end cap is threaded onto the outer wall of the sleeve. The support bar is made of high-strength metal and has an overall arc-shaped structure. After the sleeve is rotated and adjusted, the end cap rotates and presses against the outer wall of the sphere to fix the position of the sleeve.

[0009] Preferably, the outer wall of the bolt is threaded with a nut, and the nut is pressed against the ear plate. By setting the nut, the four semicircular sleeves are fixed in position in pairs.

[0010] Preferably, the inner wall of the recess is slidably connected to the outer wall of the support sleeve.

[0011] Preferably, each of the two pads has two foot holes on its outer wall, and the inner walls of the four foot holes are slidably connected with foot nails, which fix the pads to the mounting surface.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution provides stable arc support for the cable body through the cooperation of four semi-circular sleeves and support bars, avoiding excessive bending. The support bars can disperse the stress when the cable is bent, preventing excessive stretching on the outside and excessive compression on the inside. With the angle adjustment of the sleeves, balls and ball sleeves and the telescopic function of the threaded rod, it can adapt to the angle and shape of different bends or corners, allowing the pad to fit tightly against the fixing point, enhancing the support stability. In addition, this structure does not require the whole cable body to be inserted and then moved to the installation point. It can be assembled and fixed directly at the installation position during operation, which greatly simplifies the operation process and improves the applicability during installation.

[0021] Depend on Figures 1-3 As shown, a bend-resistant cable is disclosed, including an open rubber sleeve 1. A support strip 2 is fixedly connected to the outer wall of the open rubber sleeve 1. During the bending process of the cable, the support strip 2 can play the role of arc support, effectively resisting bending force and preventing the cable from bending excessively. Two semi-circular sleeves 3 are fixedly connected to both ends of the open rubber sleeve 1. The four semi-circular sleeves 3 are hinged together in pairs to facilitate wrapping the cable body 4. When they are combined, they can form a stable clamp on the cable body 4 and restrict the movement of the cable body 4 in the radial direction.

[0022] The cable body 4 is placed inside the open rubber sleeve 1. The outer walls of the four semi-circular sleeves 3 are all fixedly connected with ear plates 5. The outer walls of the four ear plates 5 are all provided with through holes. The four through holes are slidably connected to bolts 6 in pairs. The outer walls of the bolts 6 are threaded with nuts 7. The nuts 7 and the ear plates 5 are pressed together. The through holes on the ear plates 5 cooperate with the bolts 6 and nuts 7 to firmly fix the pairs of semi-circular sleeves 3.

[0023] The outer walls of the two semicircular sleeves 3 are fixedly connected to ball sleeves 8, and the inside of the two ball sleeves 8 is rotatably connected to a ball 9. The outer walls of the two ball sleeves 8 are provided with recesses 10, and the inner walls of the recesses 10 are slidably connected to the outer walls of the support sleeve 11. The ball 9 rotates inside the ball sleeves 8, so that the support sleeve 11 can achieve multi-angle rotation.

[0024] The outer wall of the sphere 9 is provided with a support assembly, which includes two sleeves 11. The outer wall of the sleeve 11 is threaded with an end cap 16, which can limit the position of the sleeve 11. The outer walls of the two spheres 9 are respectively fixedly connected to one end of the two sleeves 11. The inner walls of the two sleeves 11 are threaded with threaded rods 12. One end of the two threaded rods 12 is fixedly connected with a pad 13. The outer walls of the two pads 13 are provided with two foot holes 14. The inner walls of the four foot holes 14 are slidably connected with foot nails 15. The foot holes 14 on the pad 13 cooperate with the foot nails 15 to firmly fix the pad 13 at the bend or corner.

[0025] Working principle: When the cable body 4 is laid, at bends or corners, to prevent excessive bending of the cable body 4 during this process, two pads 13 are fixed at the bends or corners through four foot holes 14 and four foot nails 15. Depending on the position and angle of the fixing point, the threaded rod 12 is rotated through the support sleeve 11 to cause the pads 13 to extend or retract. The support sleeve 11 can rotate with the ball 9 within the ball sleeve 8 to allow for angle adjustment, enabling the pads 13 to fit snugly against the outer wall of the fixing point for better adhesion. The four semicircular sleeves 3, the support bar 2, and the cable body 4 are supported. The cable body 4 is placed between the four semicircular sleeves 3 and inside the open rubber sleeve 1. The four semicircular sleeves 3 are rotated and merged in pairs through the hinge position, so that the four ear plates 5 are brought close to each other in pairs. Then, two bolts 6 are inserted into the two sets of ear plates 5, and two nuts 7 are screwed into the two bolts 6 to fix the two sets of semicircular sleeves 3. When the cable body 4 is supported in an arc shape, it is supported by the support bar 2.
