Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, and particularly relates to a cable laying tray. Background Art

[0002] A cable tray is a structure used to support and protect cables. According to the structural form, cable trays can be divided into trough type, tray type, ladder type, grid type, etc. Cable trays can not only improve the space utilization rate and the overall aesthetic degree of buildings, but also facilitate the laying, maintenance and later maintenance management of cables. Existing cables are generally stacked in cable trays. When it is necessary to lead down one or several cables, due to the friction between cables and the friction between cables and cable trays, it is difficult to lead down the cables, and the cables at the leading end will continuously rub against the trays, resulting in damage to the cable skin, thereby affecting the subsequent signal transmission quality of the cables. Content of the Utility Model

[0003] The purpose of the utility model is to design a cable laying tray, which can prevent cables from being stacked in the cable tray and the cables at the leading end from rubbing against the tray too much, so as to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A cable laying tray is provided, which includes a tray body. At least one cable auxiliary component is installed in the tray body. The cable auxiliary component includes a fixing plate, an auxiliary seat, a rotating rod and a plurality of guide wheels. The fixing plate is installed on the tray body. The auxiliary seat is installed on the fixing plate. Two ends of the rotating rod respectively pass through two sides of the auxiliary seat and are rotatably connected with the auxiliary seat. A plurality of the guide wheels are installed on the rotating rod, and the guide wheels cooperate with the cables.

[0005] Further, through holes are respectively formed in two sides of the auxiliary seat, and the through holes cooperate with the guide wheels.

[0006] Further, mounting frames are installed on two sides inside the tray body. A plurality of notches are formed in the mounting frames, and two ends of the fixing plate of the cable auxiliary component can be clamped into the notches.

[0007] Further, the notches are T-shaped notches.

[0008] Further, a concave groove is formed at the bottom end of the fixing plate, and a T-shaped fixing column is arranged in the concave groove. The lower part of the T-shaped fixing column can extend outwards to cooperate with the notch.

[0009] Further, a protective cover is movably connected to the top end of the tray body.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] By providing a cable auxiliary component in the present utility model, each cable corresponds to a guiding wheel, separating the cables so that the cables will not accumulate in the cable tray. When it is necessary to lead one or several cables downward, due to the function of the guiding wheel, the cables are easy to be led downward, and the cables at the leading end will not have excessive friction with the cable tray, and the cable skin will not be damaged, ensuring the subsequent signal transmission quality of the cables.

[0019] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific implementation manners, structures, features and their effects of the present invention as follows.

[0020] Embodiment: Refer to Figures 1-4, A cable laying bridge, including a bridge body 1, with a protective cover 12 movably connected to the top of the bridge body 1. The movable connection method can be hinged, plug-in type or push-pull type, which is convenient for operating inside the bridge body 1. At least one cable auxiliary component 2 is installed inside the bridge body 1. The cable auxiliary component 2 includes a fixing plate 3, an auxiliary seat 4, a rotating rod 5 and a plurality of guide wheels 6. The fixing plate 3 is installed on the bridge body 1, the auxiliary seat 4 is installed on the fixing plate 3. Both ends of the rotating rod 5 pass through both sides of the auxiliary seat 4 and are rotatably connected to the auxiliary seat 4. A plurality of guide wheels 6 are installed on the rotating rod 5, and the guide wheels 6 cooperate with the cables. Each cable corresponds to one guide wheel 6, separating the cables so that the cables will not accumulate in the cable bridge. When it is necessary to lead down one or several cables, due to the function of the guide wheels 6, the cables are easy to lead down, and the cable at the leading end will not have too much friction with the bridge, and the cable skin will not be damaged, ensuring the subsequent signal transmission quality of the cable. Through holes 7 are respectively opened on both sides of the auxiliary seat 4. The through holes 7 cooperate with the guide wheels 6, and the through holes 7 can allow the cables to pass through, which can limit the positions of the cables so that the cables will not be staggered.

[0021] Installation frames 8 are installed on both sides inside the bridge body 1. A plurality of notches 9 are opened on the installation frames 8. Both ends of the fixing plate 3 of the cable auxiliary component 2 can be clamped into the notches 9, so that multiple layers of cable auxiliary components 2 can be placed, and as many cables as possible can be laid in a limited space. The notch 9 is a T-shaped notch 9. Concave grooves 10 are opened on both sides of the bottom end of the fixing plate 3. T-shaped fixing columns 11 are provided in the concave grooves 10. The lower part of the T-shaped fixing column 11 can extend outwards to cooperate with the lower part of the T-shaped notch 9; at the same time, there is a certain distance between the upper end of the T-shaped fixing column 11 and the top end of the concave groove 10, so that the T-shaped fixing column 11 can expand and contract in the concave groove 10. When the T-shaped fixing column 11 retracts into the concave groove 10, both ends of the fixing plate 3 of the cable auxiliary component 2 can be clamped into the notch 9 until the lower part of the T-shaped fixing column 11 is directly below the lower part of the T-shaped notch 9. The T-shaped fixing column 11 extends out of the concave groove 10 and extends into the lower part of the T-shaped notch 9 to limit the position of the cable auxiliary component 2.

[0022] The working principle of this embodiment: According to the installation requirements of the cables, both sides of the cable auxiliary component 2 are installed in the notches 9 on the brackets and fixed through the cooperation of the T-shaped fixing columns 11 and the notches 9. The cables are laid through the through holes 7 and the guide wheels 6; when it is necessary to lead down one or several cables, due to the function of the guide wheels 6, the cables are easy to lead down, and work like this.
