[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0033] See also Figure 1-Figure 5 , the utility model provides a technical solution: Example 1:
[0034] A tensile and fracture-resistant MPP cable protection tube comprises a tube body 1, with a plurality of shells 2 fixedly connected to both sides of the tube body 1, and a clamping mechanism provided inside the shells 2 to limit the position of the cable;
[0035] In one embodiment of the present invention, the clamping mechanism includes a driving rod 3 disposed inside the housing 2. One end of the driving rod 3 extends through the interior of the tube 1 and is movably connected to a clamping block 4. The inner wall of the housing 2 is provided with a through hole 5 for use with the driving rod 3.
[0036] The buffer mechanism is fixedly arranged on the driving rod 3 and can provide buffering while the clamping block 4 clamps the cable.
[0037] The clamping mechanism also includes a threaded rod 6 threadedly connected to one side of the housing 2. A bearing 7 is provided at one end of the threaded rod 6, and the threaded rod 6 is rotatably connected to one end of the drive rod 3 through the bearing 7. A threaded hole 8 is provided on one side of the housing 2.
[0038] In this embodiment, it is taken into consideration that the existing MPP cable protection tube fixing method of the cable is too limited and cannot be reasonably adjusted according to the cable diameter, which will affect the stability of the cable and thus affect the tensile strength. Therefore, by setting a clamping mechanism, the cable can be moved between two adjacent clamping blocks 4, and then the twisting block 15 is rotated, while driving the threaded rod 6 to rotate inside the threaded hole 8. The threaded rod 6 will move to the side close to the cable, while driving the bearing 7, the driving rod 3 and the limit block 12 to move along the trajectory of the sliding block 13 and the sliding groove 14, and at the same time drive the clamping block 4 and the protective pad 18 to move, clamping the cable, thereby achieving the effect of clamping and fixing, which can effectively prevent the cable from being stretched by external force and causing breakage. At the same time, the clamping size can be appropriately adjusted according to cables of different sizes, further improving the stability of the cable.
[0039] The invention solves the problem that the existing MPP cable protection tube fixing method of the cable is too limited and cannot be reasonably adjusted according to the cable diameter, which will affect the stability of the cable and further affect the anti-tensile effect.
[0040] Preferably, the surface of the driving rod 3 is fixedly connected to a limit block 12 , both sides of the limit block 12 are fixedly connected to sliding blocks 13 , and the inner wall of the housing 2 is provided with a sliding groove 14 used in conjunction with the sliding block 13 .
[0041] In this embodiment, by setting the limit block 12, the sliding block 13 and the sliding groove 14, the movement trajectory of the drive rod 3 and other structures can be limited, so that they can only move along the trajectory of the sliding block 13 and the sliding groove 14 during the movement process, thereby improving the stability during the movement process.
[0042] Preferably, one end of the threaded rod 6 is fixedly connected to a twisting block 15 , and twisting grooves 16 are formed on the top and bottom of the twisting block 15 .
[0043] In this embodiment, the twisting block 15 and the twisting groove 16 are provided to provide a gripping point for twisting the threaded rod 6 so that the user can easily rotate the threaded rod 6 .
[0044] Preferably, a sealing ring 17 is fixedly connected to the inner wall of the through hole 5 , and the inner wall of the sealing ring 17 is in close contact with the surface of the driving rod 3 .
[0045] In this embodiment, the sealing ring 17 is provided to seal the gap between the driving rod 3 and the through hole 5 , thereby preventing liquids such as groundwater and moisture from leaking into the interior of the tube body 1 .
[0046] Preferably, a protective pad 18 is fixedly connected to one side of the clamping block 4 , and the material of the protective pad 18 is rubber.
[0047] In this embodiment, the protective pad 18 is provided to prevent the clamping block 4 from directly contacting the cable and causing cable loss, thereby playing a protective role. Example 2:
[0048] On the basis of Example 1, the clamping mechanism of this embodiment can clamp the cable through the symmetrical clamping block 4 to achieve the effect of fixing the cable. However, considering that the clamping mechanism directly and rigidly clamps the cable, it may cause the cable to bend and be damaged. The buffer mechanism in this application includes a connecting block 9 fixedly connected to one side of the clamping block 4, and a buffer groove 10 is provided on one side of the connecting block 9. The inner wall of the buffer groove 10 is fixedly connected to a spring 11, and one end of the spring 11 is fixedly connected to one end of the driving rod 3.
[0049] In this embodiment, considering that the clamping mechanism directly clamps the cable rigidly, which may cause the cable to bend and be damaged, a buffer mechanism is provided. When the clamping block 4 and the protective pad 18 are in contact with the cable, the spring 11 will slowly compress them, thereby achieving a buffering effect and effectively avoiding the phenomenon of cable bending and damage caused by rigid contact.
[0050] The invention solves the problem that the cable may be bent and damaged due to the rigid clamping of the cable by the clamping mechanism.
[0051] Working principle: by moving the cable between two adjacent clamping blocks 4, then rotating the twisting block 15, and at the same time driving the threaded rod 6 to rotate inside the threaded hole 8, the threaded rod 6 will move to the side close to the cable, and at the same time drive the bearing 7, the driving rod 3 and the limit block 12 to move along the track of the sliding block 13 and the sliding groove 14, and at the same time drive the clamping block 4 and the protective pad 18 to move, clamping the cable, thereby achieving the effect of clamping and fixing, which can effectively prevent the cable from being stretched by external force and causing breakage. At the same time, the clamping size can be appropriately adjusted according to the size of the cable, further improving the stability of the cable;
[0052] When the clamping block 4 and the protective pad 18 are in contact with the cable, the spring 11 will be slowly compressed, thereby achieving a buffering effect, effectively avoiding the phenomenon of cable bending and damage caused by hard contact.
[0053] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
