Description

Technical Field

[0001] The present invention belongs to the technical field of electrical protection equipment, and particularly relates to a cable protection trough that can cross obstacles. Background Art

[0002] A cable protection trough is an electrical protection device that protects cables from being squeezed by vehicles or other sharp objects, and is made of high-strength rubber or PVC. Each cable protection trough has a plug connector and a socket slot. When in use, the plug connector of the latter cable protection trough is connected to the socket slot of the previous cable protection trough.

[0003] However, currently, cable protection troughs can only be used on flat roads. If the laid cables pass over raised obstacles such as curbs or thresholds on the roadside, due to the bending of the cables, the cable protection troughs cannot protect the cables well.

[0004] In the face of this situation, the current solution is to still use the existing cable protection troughs and place the cable protection troughs obliquely on the obstacles to achieve the effect of protecting the cables. However, this method cannot play a good role in protecting the cables because the contact area between the obliquely placed cable protection troughs and the obstacles is very small, and the generated frictional force is also very small. It is very difficult to stably place them on the surface of the obstacles, resulting in the cables being easily displaced and falling out of the cable protection troughs, losing protection, and causing serious safety hazards such as damage to the cable insulation layer. Summary of the Invention

[0005] The purpose of the present invention is to provide a cable protection trough that can cross obstacles. The cable protection trough has a simple structure, stable performance, and is durable. It can cross obstacles to protect cables when passing over raised obstacles, enhancing the safety and reliability of the cables.

[0006] The technical solution for achieving the purpose of the present invention: A cable protection trough that can cross obstacles, which includes: a plug base, a connection base, a socket base, a cylindrical damping rotating shaft, a plug connector, a socket slot, a cover plate, a cylindrical rotating shaft, and a trough body. The plug base, the connection base, and the socket base are sequentially connected. The plug base and the connection base are connected by a cylindrical damping rotating shaft, and the connection base and the socket base are connected by a cylindrical damping rotating shaft. The cover plate is located above the plug base, the connection base, and the socket base, and the cover plate is respectively connected to the plug base, the connection base, and the socket base by a cylindrical rotating shaft. Channels are opened inside the plug base, the connection base, and the socket base to form a trough body, and the trough bodies communicate with each other. Plug connectors are symmetrically arranged at the front of the plug base, and socket slots that cooperate with the plug connectors are symmetrically arranged at the rear of the socket base.

[0007] The cylindrical damping rotating shaft is fixedly connected to the top of the rear of the plug base and the top of the front of the connection base.

[0008] The cylindrical damping rotating shaft is fixedly connected to the top of the rear part of the connection base and the top of the front part of the socket base.

[0009] There are multiple connection bases, and adjacent connection bases are connected by a cylindrical damping rotating shaft.

[0010] The cylindrical damping rotating shaft is fixedly connected to the bottom ends of adjacent connection bases.

[0011] The maximum opening and closing angle of the cylindrical damping rotating shaft is 270°.

[0012] Grooves adapted to the cover plate are provided on the upper parts of the plug base, the connection base, and the socket base, and the inner depth of the groove is the same as the thickness of the cover plate.

[0013] The cylindrical rotating shaft is fixedly connected to one end parallel to the length direction of the cable protection groove on the inner side of the groove and one end of the cover plate corresponding to one end on the inner side of the groove.

[0014] The maximum opening and closing angle of the cylindrical rotating shaft is 180°.

[0015] The plug connector is formed by protruding from the front part of the plug base and forms an integrally molded structure with the plug base.

[0016] The plug socket is formed by recessing from the rear part of the socket base and forms an integrally molded structure with the socket base.

[0017] There are multiple groove bodies, and each groove body is parallel to each other and separated from each other along the length direction of the cable protection groove.

[0018] The beneficial technical effects of the present invention are as follows:

[0019] (1) In the cable protection groove capable of crossing obstacles of the present invention, the bases are connected by a cylindrical damping rotating shaft, and a maximum opening and closing angle of 270° can be achieved and the opening and closing angle can be kept fixed, so that when the cable protection groove encounters an obstacle, it can cross the obstacle and be stably arranged above the obstacle without displacement during use, realizing effective protection of the cable.

[0020] (2) The cable protection groove capable of crossing obstacles of the present invention can realize the connection and disconnection of multiple cable protection grooves through the detachable connection of the plug connector and the plug socket.

Detailed Embodiments

[0029] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0030] As Figures 1-3 shown, a cable protection trough capable of crossing obstacles provided by the present invention includes a plug base 1, a connection base 2, a slot base 3, a cylindrical damping rotating shaft 4, a plug connector 5, a plug slot 6, a cover plate 7, a cylindrical rotating shaft 8, and a trough body 9. The plug base 1, the connection base 2, and the slot base 3 are connected in sequence from left to right. The front part of the plug base 1 protrudes to form two symmetrical plug connectors 5, and the rear part of the slot base 3 is recessed to form two symmetrical plug slots 6. The positions of the plug connectors 5 and the plug slots 6 are arranged in a matching manner, and the plug connectors 5 and the plug slots 6 are connected in a detachable manner, so that the connection and disassembly of multiple cable protection troughs can be realized according to the actual use situation.

[0031] As Figure 1As shown in the figure, the cylindrical damping rotating shaft 4 is made of stainless steel and includes a cylinder and two hinges. The two hinges are rotatably connected to the cylinder to enable manual opening and closing. The plug base 1 and the connection base 2 are connected by the cylindrical damping rotating shaft 4. One hinge of the cylindrical damping rotating shaft 4 is fixed to the top of the rear part of the plug base 1 by screws, and the other hinge is fixed to the top of the front part of the connection base 2 by screws. The connection base 2 and the slot base 3 are connected by the cylindrical damping rotating shaft 4. One hinge of the cylindrical damping rotating shaft 4 is fixed to the top of the rear part of the connection base 2 by screws, and the other hinge is fixed to the top of the front part of the slot base 3 by screws. There are 3 connection bases 2, and adjacent connection bases 2 are connected by the cylindrical damping rotating shaft 4. The two hinges of the cylindrical damping rotating shaft 4 are respectively fixed to the bottom ends of the adjacent connection bases 2 by screws.

[0032] Between the plug base 1 and the connection base 2, between the connection base 2 and the slot base 3, and between adjacent connection bases 2, the cylindrical damping rotating shaft 4 can achieve a maximum opening and closing angle of 270°. According to the shape and size of the obstacle, the opening and closing angle between the bases can be correspondingly adjusted through the cylindrical damping rotating shaft 4 and the opening and closing angle can be kept fixed, finally realizing that the cable protection groove is stably placed on the surface of the obstacle.

[0033] As Figure 2 shown in the figure, multiple covers 7 are respectively located on the upper parts of the plug base 1, the connection base 2 and the slot base 3. The cover 7 and the plug base 1 are connected by a cylindrical rotating shaft 8. The cover 7 and the connection base 2 are connected by a cylindrical rotating shaft 8. The cover 7 and the slot base 3 are connected by a cylindrical rotating shaft 8. The cover 7 can be opened and closed by 180° through the cylindrical rotating shaft 8. After being opened, the groove body 9 is exposed. Cables can be placed in the groove body 9. Then the cover 7 is covered, and the cover 7 will be fastened due to its own gravity and the friction with the base groove, thus realizing the protection of the cables. The surface of the cover 7 is painted with yellow and black warning colors to make it have a good warning effect.

[0034] As Figure 3As shown in the figure, the longitudinal sections of the plug base 1, the connection base 2, and the slot base 3 are isosceles trapezoids with the same dimensions. Grooves are provided on the upper parts of the plug base 1, the connection base 2, and the slot base 3. The grooves are adapted to the cover plate 7, and the inner depth of the grooves is the same as the thickness of the cover plate 7. The cover plate 7 is fixed in the groove of the plug base 1 through a cylindrical rotating shaft 9. The cylindrical rotating shaft 8 is made of stainless steel and includes a cylinder body and two hinge leaves. The two hinge leaves are rotatably connected to the cylinder body, enabling manual opening and closing. One hinge leaf of the cylindrical rotating shaft 8 is fixedly connected to one end of the inner side of the groove parallel to the length direction of the cable protection groove through a screw, and the other hinge leaf is fixedly connected to one end of the cover plate 7 corresponding to the one end of the inner side of the groove through a screw. Thus, after the cover plate 7 is closed, the upper surface of the cover plate 7 is flush with the upper surfaces of the plug base 1, the connection base 2, and the slot base 3 except for the grooves. Three channels parallel to each other and separated from each other along the length direction of the cable protection groove are provided inside the plug base 1, the connection base 2, and the slot base 3, forming a groove body 9. And the groove bodies 9 inside each base communicate with each other for passing cables and placing multiple cables separately to prevent cable entanglement.

[0035] As Figure 4 shown, the usage process of a cable protection groove capable of crossing obstacles provided by the present invention is as follows: Place the plug base 1 and the slot base 3 on a flat road surface, lift the connection base 2, and place the connection base 2 on the obstacle 11. Between the plug base 1 and the connection base 2, between the connection base 2 and the slot base 3, and between adjacent connection bases 2, according to the shape and size of the obstacle 11, adjust the opening and closing angles between the bases through the cylindrical damping rotating shaft 4 and keep the opening and closing angles fixed, so that the cable protection groove is stably placed on the surface of the obstacle. Then open the cover plate 7 on the upper parts of the plug base 1, the connection base 2, and the slot base 3 to 180°, expose the groove body 9, place the cable 10 into the groove body 9, and then cover the cover plate 7 to keep the upper surface of the cover plate 7 flush with the upper surfaces of the plug base 1, the connection base 2, and the slot base 3. Because the contact area between the connection base 2 and the obstacle is large, and the plug base 1 and the slot base 3 are placed flat on the ground, the friction generated is also very large. During use, the cable protection groove will not displace, and the cable will not displace either, effectively protecting the cable and eliminating serious safety hazards such as damage to the cable insulation layer.
