[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example

[0024] This embodiment provides a hidden assembled wire trough light bridge, including a bridge body 1, a connecting plate 3, a plurality of connecting pieces with different structures, and a line dividing mechanism 16 installed in the inner cavity 5 of the bridge. Figure 1 As shown, the wire trough light bridge is assembled together by fixing the above-mentioned structures with bolts, and is fixedly installed by the hanger 12 and the positioning line popped out from the ceiling, and the lamps and their related wires are installed inside the above-mentioned structure, thereby forming a hidden and traceless assembled wire trough light bridge decorative structure.

[0025] Specifically, Figure 1 and Figure 2 As shown, the cross section of the bridge main body 1 is a horizontal C-shaped structure, with a lamp hole 2 at the bottom. The size of the lamp hole is adaptively opened according to the width of the actual lamp, and the position of the lamp hole opened on the bridge main body is adaptively arranged according to the actual construction site. The upper edge of the bridge main body is bent inward to form a bending portion 14, and a series of mounting holes 6 are symmetrically opened on both sides near the end of the bending portion. In this embodiment, a total of three pairs of mounting holes are opened as bolt mounting holes. Figure 2As shown, the bridge frame body in this embodiment includes two structures in total, wherein Figure 2 (a) shows the main structure of the bridge with lamp holes, that is, the lamp hole positions are determined according to the size of the lamp holes to be installed during modeling, and the lamp holes are arranged in the center or offset according to the length of the bridge body; Figure 2 (b) shows the main structure of the bridge without light holes. That is, because the indoor lamps are evenly spaced, the parts where lamps are not needed can be Figure 2 (b) The main structure of the bridge is assembled and connected. The two structures have the same size and can be matched and connected accordingly.

[0026] The configuration of the bridge main body 1 of the utility model provides two structural options. This modular design makes the bridge more flexible and changeable in application. When assembling the light bridge with lamp hole type wire trough, lamps can be installed at the same time. The luminous part of the lamp is fixed at the position of the lamp hole and faces the outside, and the non-luminous part is hidden in the bridge, which not only realizes the integrated installation of the lamp and the bridge, but also achieves the purpose of hiding the lamp. And because the lamp and the bridge main body are installed in an integrated manner, only one installation cost is involved, and there is no cost for fixing the lamp twice in the later stage, which reduces the construction cost; and the appearance is simple and generous, which can be integrated with various interior decoration styles and will not destroy the overall aesthetic effect.

[0027] like Figure 1 and Figure 3 As shown, the bridge bodies of different structures or the bridge bodies and the connecting parts of different structures are assembled and connected through the connecting plate 3. The connecting plate is U-shaped. The width of the U-shaped connecting plate 8 is 2-3mm smaller than the inner width of the bridge body, which makes it convenient for the U-shaped connecting plate 8 to be buckled and pass through the inner flange of the upper opening of the bridge, thereby ensuring the processing accuracy of the wire trough lamp bridge and ensuring that the installation accuracy error is controlled within the minimum range during on-site assembly.

[0028] The top surface of the connecting plate is evenly distributed with a series of mounting holes 6. When installing, it is matched with the inner cavity of the bridge frame body, and the series of mounting holes on the top surface correspond to the mounting holes on the bridge frame body, and the two can be fixedly connected by bolts. Figure 3 As shown, a single hanger hole 7 is opened at the center of the connecting plate, and the hanger 12 can be fixedly installed by bolts and nuts; in this embodiment, the hanger 12 adopts Φ12 galvanized round steel with threaded ends to ensure that the bridge frame is installed stably and firmly, while abandoning the traditional double hanger + cross arm fixing method and realizing a single hanger + no cross arm fixing method, which reduces material costs and improves construction efficiency, while taking into account the quality concept of seamless assembly of the bridge frame.

[0029] And because the U-shaped connecting plate is hidden inside the bridge body 1, the grounding jumper is installed together with the U-shaped connecting plate 8 in actual application. The jumper is arranged on the ventral surface of the connecting plate, so the grounding jumper is also installed in a hidden manner, avoiding the problem of naked installation without increasing any cost, thereby ensuring the purpose of seamless assembly of the bridge.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, connectors of different shapes are fixedly connected at the corners or the middle intersection of the wire trough light bridge, including a straight three-way connector 4, an L-shaped elbow connector 8, a four-way connector 9, a Y-shaped connector 10, and a bridge 11 with a trapezoidal structure after butt connection, as shown in FIG. Figure 5 As shown, each connecting member has a plurality of flat holes on its upper flange which are the same size and center distance as the mounting holes on the bridge frame body and the connecting plate 3, serving as mounting holes for bolt connection.

[0031] By setting the above-mentioned multiple types of connectors, the present invention makes the assembly of the main body of the cable trough light bridge more flexible and efficient, and fully considers the adaptability of the bridge under different installation environments and space requirements. Whether it is a straight section, a corner or a multi-directional intersection, a suitable connection solution can be found, so that after the bridge is assembled, the transition between the components is natural and the lines are smooth, which not only meets the functional requirements of electrical wiring, but also improves the stability and aesthetics of the bridge structure; and each mechanism is also convenient for later disassembly and maintenance, reducing the difficulty and cost of maintenance. Example

[0032] On the basis of Example 1, in order to make the lines in the bridge body more neatly arranged, facilitate the later line maintenance, and avoid the lines in the bridge body being entangled with each other, thereby causing the internal lines to be chaotic, this embodiment provides another structure of the bridge body 1, and a branching mechanism 16 can also be installed in the bridge cavity 5 through a connecting rod to realize the storage and arrangement of the lines. The setting of the branching mechanism 16 needs to be combined with the position of the lamp hole to avoid interference with the position of the lamp hole, such as Figure 6-8 As shown, the line-dividing mechanism includes a line-dividing slot 17, which is a U-shaped structure, and the internal width is smaller than the internal width of the bridge body. The two sides of the top of the line-dividing slot are bent inward to form a flange 18, and the top surface of the flange is provided with a snap-fitting column 19 along the extension direction of the length of the line-dividing slot. The bottom surface of the bent portion of the bridge body above the snap-fitting column is correspondingly provided with a snap-fitting seat 15, and the snap-fitting seat 15 extends downward, the end is a spherical structure and the inner cavity is hollow, and the bottom is also provided with an opening for matching the set snap-fitting column 19. The snap-fitting seat can be made of the common PVC plastic material in the existing market, has a certain elasticity, and can realize the meshing and fixing of the snap-fitting column according to its own ductility.

[0033] like Figure 7 As shown, there are multiple holes evenly formed on the side wall of the wire dividing slot, and mounting holes evenly formed on the two side walls of the bridge body. Connecting rods 20 are provided at the corresponding positions of the holes. One end of each connecting rod is rotatably mounted with the holes on the wire dividing slot through a pin, and the other end is also rotatably connected to the side wall of the bridge body through a pin, so that the wire dividing mechanism can be offset up and down in the bridge body. In the inner cavity of the wire dividing slot, axial holes are spaced apart in a direction perpendicular to the length extension of the engaging column, and a wire dividing column 21 is movably inserted in the axial hole, that is, the wire dividing column can flexibly move up and down in the corresponding axial hole, as shown in FIG. Figure 7 As shown, the evenly distributed branching posts 21 have a comb-tooth structure in appearance, and the top gap of the branching posts is smaller than the bottom gap. The top is designed in a spherical structure and has a certain flexibility, so as to facilitate the separation of the wires.

[0034] Furthermore, if Figure 8 As shown, in the initial state, the bottom surface of the branching trough is in contact with the bottom of the inner cavity of the bridge frame body, and the bottom of each branching column is supported by the bridge frame body and extends upward, and the wires are separated by the branching columns; or when the wiring through the inside of the bridge frame increases, the branching trough 17 can be pushed upward, and the connecting rod can be rotated to make it move upward in an inclined direction until the snap-fit ​​column 19 matches the snap-fit ​​seat 15 at the upper position, so that the branching trough is fixed to the middle position of the inner cavity of the bridge frame, so that the inner cavity of the bridge frame body is divided into two upper and lower chambers, and both chambers can be used for the lines to pass through; at the same time, after each branching column 21 in the branching trough is separated from the support of the inner bottom surface of the bridge frame body, it freely falls from the bottom to extend the corresponding axial hole, so that the upper and lower parts of each branching column are respectively located in the upper and lower chambers, so that the lines located in the two chambers can use the branching columns to separate the wires, thereby effectively and reasonably realizing the allocation and use of the space in the bridge frame body, and ensuring that the wires are separated, stored and arranged, which is convenient for the classification and management of the wires.

[0035] In addition, a micro-protrusion structure can be set in the middle of the column body of each branch column, such as Figure 8 In the shaded part, the raised structure can be a ring made of rubber material or other flexible materials, which is fixedly mounted on the branching column to limit the branching column. It should be noted that in actual application, the branching mechanism can be adaptively installed in the bridge body according to the line distribution in advance, and the height of the bridge body can be appropriately increased to accommodate the branching mechanism during modeling, and the length of the branching mechanism can also be adjusted according to the actual application to avoid affecting the installation of the lamps.

[0036] The hidden assembled wire trough light bridge provided by the present invention is assembled on site. First, according to the indoor space and electrical wiring requirements, the layout of the bridge is measured and planned to determine the position of the lamps and the direction of the bridge; according to the planned layout, the bridge body 1 with or without lamp holes is placed in place, and the U-shaped connecting plate 3 is placed between adjacent bridge bodies or between the bridge body and the connecting piece, and fixed by bolts; the lamp is installed on the bridge body with lamp holes, ensuring that the luminous part of the lamp faces the outside and the non-luminous part is hidden in the bridge; the hanger is installed to ensure that the position of the hanger corresponds to the hanger hole 7 of the bridge body. According to the number and arrangement of lines, the branching mechanism is adaptively selected to install, and the bridge body is divided into two chambers by the branching mechanism, and the wires are passed through the bridge body and the branching trough, and the wires are separated and fixed by the branching column. Finally, check whether all connections are firm, whether the wires are arranged correctly, and whether the lamps are installed in place; after the assembly is completed, necessary debugging can also be carried out to ensure the normal operation of the electrical system.

[0037] This new model realizes the assembly of the wire trough light bridge, and the modular design allows the user to choose the bridge body with different structures according to actual needs to adapt to different installation environments and lamp layouts, with strong flexibility; the lamps and wires are hidden inside the bridge, reducing the exposed messy wires, making the indoor space look more tidy and beautiful; providing connectors of various shapes to meet the installation needs of straight sections, corners or multi-directional intersections, improving the applicability of the bridge; through the flexible adjustment of the branching mechanism, the space in the bridge is effectively allocated, and the space utilization rate is improved; this new model comprehensively considers various factors such as beauty, practicality, economy and safety, and provides users with an efficient, flexible and durable indoor electrical wiring solution.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
