Description

Technical Field

[0001] The utility model relates to a self-locking bridge for cable laying, and in particular to a self-locking bridge for cable laying applied in the technical field of cable bridges. Background Art

[0002] Cable trays are commonly used supporting and protecting devices for cable laying in the power supply system of electrical equipment. They protect and guide the cables laid in the cable trays. However, the existing cable trays generally place multiple cables without separating them. When one of them fails, the cables will be in contact and entangled with each other, making it difficult to pull them out, making it inconvenient for inspection and maintenance. Therefore, they need to be protected by cable trays.

[0003] The specification of Chinese patent CN210536195U discloses a new type of adjustable cable tray, including a first bridge frame body and a second bridge frame body, a rotating assembly and a fixing mechanism are provided between the first bridge frame body and the second bridge frame body, and a circular plate is welded to the top of the outer walls on both sides of the first bridge frame body and the second bridge frame body, and a mounting plate is provided through the inside of the circular plate, and the mounting plate is a concave structure, and the side wall of the circular plate is threadedly connected with a locking bolt. The utility model overcomes the shortcomings of the prior art and facilitates different cable laying requirements by providing a first bridge frame body and a second bridge frame body that can be bent freely. When in use, the first bridge frame body forms a rotational connection with the second bridge frame body through the rotating assembly, so that the first bridge frame body and the second bridge frame body can be bent freely in the horizontal direction, and the angle between the two can be changed, so that the laying direction of the cable can be freely adjusted in the horizontal direction.

[0004] The specification of Chinese patent CN220066733U discloses a cable tray, including a cable tray main body, a supporting leg is installed at the bottom of the cable tray main body, a transverse partition is clamped on the inner side wall of the cable tray main body, and vertical partitions are clamped on the bottom of the inner cavity of the transverse partition and the cable tray main body. Several rows of connecting sockets are arranged at equal intervals from top to bottom on the relative inner side walls of the cable tray main body, and each row of connecting sockets is arranged at equal intervals. A card slot is arranged in the connecting socket, and several card plates 2 are arranged at equal intervals on both sides of the bottom of the transverse partition, and the card plates 2 are inserted into the card slots. Several rows of card holes are opened on the bottom of the inner cavity of the cable tray main body and on the top of the transverse partition, and each row of card holes is arranged at equal intervals. Several card plates 1 are arranged at equal intervals on the lower part of the vertical partition, and the card plates 1 are clamped in the card holes. This structure can make full use of the space of the cable tray main body, so that it can adapt to the separated arrangement of various different cables and has better applicability.

[0005] The existing cable tray has a simple internal structure and is not suitable for the separate arrangement of a large number of cables, which results in that a large number of cables are easily mixed together when arranged, resulting in poor applicability. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the existing cable tray has a simple structure and cannot be used to separate and arrange more cables, which results in that more cables are easily mixed together when arranged, resulting in poor applicability.

[0007] In order to solve the above problems, the utility model provides a self-locking bridge for cable laying, including a bridge body, a bending plate fixedly connected to the top of the bridge body, a sliding cover slidably connected to the bending plate, and the bottom of the sliding cover is engaged with the bending plate, a plurality of through holes are equidistantly drilled at the bottom of the bridge body, and two adjacent through holes are mirror-imaged, a flap is connected to the inner wall of the through hole by rotation, grooves are symmetrically drilled on the inner wall of the through hole, rotating shafts corresponding to the grooves are fixedly connected at both ends of the flap, and the rotating shafts are engaged with the grooves, and a support plate is fixedly connected to the side of the bottom of the through hole on one side of the arc facing away from the flap.

[0008] In the above-mentioned cable tray, multiple cables can be effectively laid separately while being protected and dustproof.

[0009] As a further improvement of the present application, when the support rod contacts the support plate, the flip cover and the through hole are in a vertical state.

[0010] As a further improvement of the present application, a plurality of first screw holes are equidistantly drilled on the side walls at both ends of the bridge body, and a dividing line is painted between two adjacent first screw holes.

[0011] As a further improvement of the present application, two connecting pieces are detachably connected to the side ends of the bridge body, a sealing gasket is fixedly connected to the inner wall of the connecting piece, and the connecting piece is sleeved on the bridge body and the sliding cover surface.

[0012] As another improvement of the present application, two connecting members are staggered and fixedly connected with a clamping block near one end thereof, and the two clamping blocks are engaged with each other.

[0013] As another improved supplement of the present application, a second screw hole is symmetrically drilled on the side end of the connecting piece, and the second screw hole is threadedly connected to the first screw hole through a bolt.

[0014] As another improved supplement of the present application, a force-bearing plate is symmetrically fixedly connected to the bottom end of the flip cover, a support rod is rotatably connected between the two force-bearing plates, and the support rod is in conflict with the support plate through rotation.

[0015] To sum up, the present scheme can be realized. When laying cables, the bridge body can be fixed on the mounting frame. At this time, the flap and the through hole are stamped and formed at a 90-degree state. At this time, a partition is formed between each two adjacent flaps, thereby automatically forming three groups of partitions. Subsequently, different cables can be installed in corresponding partitions respectively, thereby avoiding mixing and entanglement of multiple cables. After the cables are laid, the sliding cover can be engaged with the bending plate from the side of the bridge body, and then the top of the bridge body can be covered by sliding the sliding cover to reach a self-locking state, thereby effectively achieving the separation and laying of multiple cables while providing them with protection and dustproof effects.

[0025] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0026] The first implementation method:

[0027] Figure 1-6A self-locking bridge for cable laying is shown, comprising a bridge body 1, a bending plate 2 is fixedly connected to the top of the bridge body 1, a sliding cover 3 is slidably connected to the bending plate 2, and the bottom of the sliding cover 3 is engaged with the bending plate 2, a plurality of through holes 5 are equidistantly opened at the bottom end of the bridge body 1, and two adjacent through holes 5 are mirror-imaged, a flap 11 is fixedly connected to the inner wall of the through hole 5, and the flap 11 and the through hole 5 are of integrated design.

[0028] This solution can be achieved. When laying cables, the bridge body 1 can be fixed on the mounting frame. At this time, the flap 11 and the through hole 5 are stamped and formed at a ninety-degree state. At this time, a partition is formed between each two adjacent flaps 11, thereby automatically forming three groups of partitions. Subsequently, different cables can be installed in corresponding partitions respectively, thereby avoiding multiple cables from being mixed and entangled together. After the cables are laid, the sliding cover 3 can be engaged with the bending plate 2 from the side of the bridge body 1, and then the bridge body 1 can be covered by sliding the sliding cover 3 to reach a self-locking state, thereby effectively achieving the separation and laying of multiple cables while providing them with protection and dustproof effects.

[0029] The second implementation method:

[0030] Figure 1-2 It is shown that a flap 11 is rotatably connected to the inner wall of the through hole 5, and grooves 13 are symmetrically excavated on the inner wall of the through hole 5. Rotating shafts 12 corresponding to the grooves 13 are fixedly connected at both ends of the flap 11, and the rotating shaft 12 is engaged with the grooves 13. A support plate 18 is fixedly connected to the side of the bottom of the through hole 5 on one side of the arc away from the flap 11, and a force plate 16 is symmetrically fixedly connected to the bottom end of the flap 11. A support rod 17 is rotatably connected between the two force plates 16, and the support rod 17 is in conflict with the support plate 18 through rotation. When the support rod 17 is in conflict with the support plate 18, the flap 11 and the through hole 5 are in a vertical state.

[0031] This solution can be achieved when laying outdoor cables. When laying cables, the bridge body 1 can be fixed on the mounting frame, and then the flap 11 can be rotated by the rotating shaft 12 to make it in a ninety-degree state. At this time, the rotating support rod 17 is in conflict with the support plate 18, so as to position the flap 11. Since the flaps 11 are all staggered, when the flaps 11 are opened, the flaps 11 respectively form two partitions with the inner wall of the bridge body 1, and a partition is formed between the two flaps 11, thereby automatically forming three groups of partitions, achieving the effect of dividing and arranging the cable lines, and at the same time, the heat can be dissipated from the inside of the bridge body 1 through the through hole 5.

[0032] The third implementation method:

[0033] Figure 1-3 and Figure 7It is shown that a plurality of first screw holes 4 are equidistantly drilled on the side walls at both ends of the bridge body 1, a dividing line 10 is painted between two adjacent first screw holes 4, two connecting members 6 are detachably connected to the side ends of the bridge body 1, a sealing gasket is fixedly connected to the inner wall of the connecting member 6, and the connecting member 6 is sleeved on the surface of the bridge body 1 and the sliding cover 3, the two connecting members 6 are staggered and fixedly connected with a clamping block 15 close to one end, and the two clamping blocks 15 are engaged with each other, second screw holes 7 are symmetrically drilled on the side ends of the connecting members 6, and the second screw holes 7 are threadedly connected to the first screw holes 4 by bolts 14, and a plurality of connecting blocks 8 are equidistantly fixedly connected to the bottom of both ends of the bridge body 1, and a third screw hole 9 is drilled on the connecting block 8.

[0034] This solution can be realized, when laying outdoor cables, when laying cables, first fit the bridge frame body 1 with the support frame through the third screw hole 9 and then fix it with screws. If the length needs to be fine-tuned, it can be cut according to the position of the dividing line 10, and the splicing is completed in sequence. After the cable is laid inside, the sliding cover 3 is covered, and the two connecting parts 6 are put on the splicing of two adjacent bridge frame bodies 1, so that the two clamping blocks 15 are engaged and positioned. At this time, the second screw hole 7 coincides with the first screw hole 4, and the connecting part 6 and the bridge frame body 1 can be fixed by the bolt 14. After the installation is completed, the sealing gasket fits tightly with the bridge frame body 1, which effectively achieves the effect of shielding and protecting the joints of the bridge frame body 1 to avoid water seepage.

[0035] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
