Description

Technical Field

[0001] The utility model relates to the technical field of wire troughs, in particular to a wire trough component for hydropower engineering construction. Background Art

[0002] Wire ducts, also known as wiring ducts, wiring ducts, and line ducts (depending on the location), are electrical tools used to organize power lines, data lines, and other wires in a standardized manner and fix them on the wall or ceiling. Wire ducts come in a variety of types, and can be divided into insulated wiring ducts, split wiring ducts, mini wiring ducts, partitioned wiring ducts, interior decoration wiring ducts, integrated insulated wiring ducts, telephone wiring ducts, Japanese telephone wiring ducts, open wire wiring ducts, circular wiring tubes, exhibition partition wiring ducts, circular floor wiring ducts, soft circular floor wiring ducts, and covered wiring ducts.

[0003] At present, the buckling structure of the wire trough is mostly concave and convex, that is, the top edge of the wire trough frame is a notch, and the bottom edge of the cover plate is convex, and it is buckled and fixed by the concave and convex structure. Such a structure is convenient for covering the cover plate, but after installation, if the cover plate needs to be removed, it is necessary to press the top edge of the wire trough frame inward to stagger the concave and convex structure. If the pressing force is too large, it will cause deformation of the wire trough frame. If the wire trough frame is made of plastic, it may even cause it to break. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figure 1-5 A cable trough assembly for hydropower engineering construction includes a support frame 1, the top surface of the support frame 1 is open, a cover plate 2 is installed at the opening position, and a plurality of equally spaced clamping columns 3 are integrally formed and installed on the left and right outer sides of the support frame 1 near the top position, the clamping columns 3 protrude from the outer surface of the support frame 1, the length of the clamping columns 3 is greater than the thickness of the cover plate 2, and the left and right sides of the cover plate 2 are reserved with clamping openings 6 corresponding to the positions of the clamping columns 3, and the clamping columns 3 are pressed into the clamping openings 6 to form a sliding limit between the cover plate 2 and the support frame 1;

[0024] A snap ring 4 is provided on the outer periphery of the clamping column 3 at the position of the bayonet 6, and the snap ring 4 is set as a half ring. The bayonet 6 and the snap ring 4 press against the outer surface of the clamping column 3 up and down to form a limit fixation between the cover plate 2 and the support frame 1. A plurality of limit balls 5 are welded and installed on the outer surface of the cover plate 2 at the outer periphery of the bayonet 6 at equal intervals. A sliding ball groove 7 is opened on the side of the snap ring 4 facing the cover plate 2, and the limit ball 5 presses into the sliding ball groove 7 to form a rotational and movable fixation of the snap ring 4 on the cover plate 2.

[0025] When in use, fix the support frame 1, and then route the cables through the support frame 1. After the routing is completed, cover the cover 2 so that the card column 3 is against the bayonet 6, and then rotate the clamping ring 4 to align it with the card column 3 at the position below the bayonet 6. The card column 3 is blocked and limited by the bayonet 6 and the clamping ring 4 above and below to form a fixation. For subsequent disassembly, reverse the clamping ring 4 to the top of the bayonet 6, and then lift the cover 2 to make the card column 3 detach from the bottom of the bayonet 6 to complete the disassembly.

[0026] In this embodiment, a plurality of internal fixing holes 16 with equal spacing are opened in the middle of the support frame 1 , and a plurality of external fixing ears 15 with equal spacing are integrally formed and installed on the left and right sides of the bottom surface of the support frame 1 .

[0027] When fixing the support frame 1, the position of the external fixing ear 15 or the position of the internal fixing hole 16 can be selected for fixing according to the fixing position. After the position of the external fixing ear 15 is fixed, when it is subsequently offset by a small distance, it is not necessary to pull the wire inside the support frame 1 to find the bolt at the position of the internal fixing hole 16, so as to facilitate disassembly. The position of the internal fixing hole 16 is fixed, and the fixing points are relatively few, so it can be fixed more quickly.

[0028] In this embodiment, a plurality of equally spaced wire openings 14 are reserved on the left and right sides of the support frame 1 , and a reserved plate 12 is provided at the position of the wire opening 14 . The outer peripheral wall of the reserved plate 12 and the inner peripheral wall of the wire opening 14 are integrally fixed by a plurality of connecting strips 13 .

[0029] When routing cables, if a cable needs to be moved out midway, the reserved plate 12 at the corresponding position can be directly chiseled open, and then the cable can be moved out from the outlet opening 14 at the position, which facilitates the routing of the cables.

[0030] In this embodiment, a plurality of equally spaced fixing seats 8 are welded and installed on the inner top surface of the support frame 1. An elliptical card slot 9 is preset on the top surface of the fixing seat 8. A card block 10 made of rubber material is plugged in the card slot 9. A spacer bar 11 is hot-melt installed on the top surface of the card block 10. The length of the spacer bar 11 is two-thirds of the height of the support frame 1.

[0031] When the cables are routed through the support frame 1, if there is a need to classify the cables, the partition bars 11 can be used to separate them into different areas to form a clear distinction and facilitate subsequent management or maintenance. When in use, hold the partition bar 11, align the card block 10 with the card slot 9 and press it to squeeze and deform the rubber card block 10 into the card slot 9 to fix it. Multiple fixing seats 8 can be used for separation using the required number of partition bars 11 according to the on-site conditions.

[0032] The components and structures not described in detail in this embodiment are well-known components and common structures or common means in the industry and are not described one by one here.
