Description

Technical Field

[0001] The utility model relates to the technical field of cable protection pipe interfaces, in particular to a cable protection pipe interface protection structure. Background Art

[0002] A cable protection tube is a metal protection tube with a certain mechanical strength that is laid on the outer layer of the cable to prevent the cable from being damaged. The cable protection tube is mainly installed in areas where communication cables and power lines intersect. Usually, if the cable protection tube is not long enough and an additional protection tube needs to be installed, an interface protection structure will be used.

[0003] There are many types of cable protection tube interface protection structures currently available. For example, there is a cable protection tube interface protection structure with Chinese patent number CN202321484951.1. This patent is achieved by respectively arranging the upper fixing mechanism and the lower fixing mechanism on the upper and lower ends of the outer wall of the protection tube connection, fixing the connection points on both sides of the outer wall of the upper fixing mechanism and the lower fixing mechanism through the inner cavity of the concave clamping block, and then inserting the screws into the inner cavity of the circular groove and the corresponding groove to fix the upper fixing mechanism and the lower fixing mechanism at the welding point of the protection tube, so as to improve the strength of the connection welding point of the protection tube. However, since this design only relies on two semicircular blocks to wrap the welding point of the protection tube, the protection is somewhat thin. If leakage or burning occurs at the welding point, it is easy to be damaged. In serious cases, it may even damage surrounding objects. Utility Model Content

[0019] The following will be combined with the 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.

[0020] See also Figure 1-4 In this embodiment, a cable protection tube interface protection structure includes a first cable protection tube 1 and a second cable protection tube 2. The connecting ends of the first cable protection tube 1 and the second cable protection tube 2 are sleeved with two parallel sleeves 3, and the two parallel sleeves 3 are both provided with a fastening mechanism 4;

[0021] The fastening mechanism 4 includes a sleeve 401, and the sleeve 401 is fixedly installed on the parallel sleeve 3. The inner wall of the sleeve 401 is threadedly connected to a threaded rod 402, and the bottom outer wall of the threaded rod 402 is fixedly connected to a bearing 403. The outer side of the bearing 403 is fixedly connected to a semi-arc clamping piece 404, wherein the two semi-arc clamping pieces 404 are provided with a flame retardant layer on one side close to the first cable protection tube 1 and the second cable protection tube 2, and the material of the flame retardant layer is ceramic silicone rubber. The ceramic silicone rubber has excellent fireproof, flame retardant, low smoke, non-toxic and other properties, which can effectively prevent the connection ends of the two protection tubes from spontaneous combustion, and then by rotating the threaded rod 402 and utilizing the linkage between the threaded rod 402, the sleeve 401 and the bearing 403, the semi-arc clamping piece 404 can move up and down, and the semi-arc clamping piece 404 is away from Two auxiliary guide rods 405 extending to the outside of the parallel sleeve 3 are fixedly installed at one end of the first cable protection tube 1 and the second cable protection tube 2, and two sliding holes compatible with the auxiliary guide rods 405 are provided on the two parallel sleeves 3, and the inner wall of the sliding hole is slidably connected to the outer wall of the auxiliary guide rod 405, and then through the cooperation of the semi-arc clamping piece 404, the auxiliary guide rod 405 and the parallel sleeve 3, the semi-arc clamping piece 404 will not rotate while moving. By adjusting the moving direction of the two semi-arc clamping pieces 404, the purpose of fixing the protection tube interface can be achieved. Therefore, this design can not only protect the connection position of the two protection tube interfaces, but also has the function of reinforcing the two interface ends, which can effectively prevent the two interface ends from disconnecting or burning, leakage and other dangerous situations.

[0022] In the case implementation, the two parallel sleeves 3 are each provided with an anti-slip layer 301 at one end close to the first cable protection tube 1 and the second cable protection tube 2. The anti-slip layer 301 can effectively pull the two protection tubes to prevent the two protection tubes from detaching.

[0023] In the case implementation, a clamping sleeve 5 is movably installed on the connecting ends of the front and rear sides of the two parallel sleeves 3, wherein two first connecting holes 302 are provided on the connecting ends of the front and rear sides of the two parallel sleeves 3, and two second connecting holes 501 that are compatible with the first connecting holes 302 are provided on the upper and lower ends of the two clamping sleeves 5. The first connecting hole 302 and the second connecting hole 501 can be connected by bolts. This design can effectively fix the two parallel sleeves 3 and thereby improve the strength of the connection of the protective tube.

[0024] In the case implementation, two limit slides 502 are welded to the inner walls of the two ferrules 5, and the connection ends on the front and rear sides of the two parallel sleeves 3 are provided with limit slides that are compatible with the limit slides 502, so that the ferrules 5 can be provided with a guiding function during installation, and it is also easier to bolt on the holes.

[0025] During implementation, follow these steps:

[0026] 1) First connect the cables inside the two protective tubes;

[0027] 2) Then clamp the two parallel sleeves 3 at the connecting ends of the two protection tubes and align them;

[0028] 3) Then clamp the two clamping sleeves 5 on the front and rear ends of the two parallel sleeves 3 respectively, and tighten the threads;

[0029] 4) Finally, by manipulating the two fastening mechanisms 4, the two semi-arc-shaped clamping pieces 404 tightly clamp the connecting ends of the two protective tubes.

[0030] In summary, the cable protection tube interface protection structure, by setting a fastening mechanism 4, first rotates the threaded rod 402, and utilizes the linkage between the threaded rod 402, the sleeve 401 and the bearing 403 to make the semi-arc clamping piece 404 move up and down, and then, through the cooperation of the semi-arc clamping piece 404, the auxiliary guide rod 405 and the parallel sleeve 3, the semi-arc clamping piece 404 will not rotate while moving, and then by adjusting the moving direction of the two semi-arc clamping pieces 404, the purpose of fixing the protection tube interface can be achieved. Therefore, this design can not only protect the position where the two protection tube interfaces are connected, but also has the function of reinforcing the two interface ends, which can effectively prevent the two interface ends from disconnecting or burning and leaking. The problem that the design only relies on two semicircular blocks to wrap the welding part of the protection tube, and the protection is somewhat thin, if leakage or burning occurs at the welding position, it is easy to be damaged, and in serious cases, it may even damage surrounding objects.
