Description

Technical Field

[0001] This utility model relates to the field of optical cable trough technology, specifically to a fireproof and protective trough structure for optical cables. Background Technology

[0002] Optical cable protection troughs, also known as cable trays, corrugated pipes, or wire troughs, are infrastructure used to protect and orderly lay optical cables (and other cables such as electrical cables and network cables). They mainly serve the functions of physical protection, organization and management, safety warning, and ease of maintenance. Classified by material, they include: HDPE (high-density polyethylene), PVC (polyvinyl chloride), MPP (modified polypropylene), metals (such as galvanized steel and stainless steel), and composite materials (such as fiberglass).

[0003] Among them, PVC optical cable protection grooves have advantages such as high hardness, good compressive strength, relatively low cost, and fire resistance, and are widely used in indoor wiring.

[0004] In existing PVC optical cable protection troughs, the optical cables are laid flat inside the trough. The width of the trough is limited. If there are many optical cables, after laying a certain number of optical cables, the excess optical cables can only be stacked at the bottom of the laid optical cables, which will lead to vertical stacking of optical cables. This is not conducive to the sorting and management of optical cables. Based on this, a fireproof optical cable protection trough structure is provided. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 In this embodiment of the utility model, a fireproof protection trough structure for optical cables includes an optical cable protection trough 1. The optical cable protection trough 1 includes a concave trough 101 and an additional track 104. The additional track 104 is fixed to the bottom of the inner side of the concave trough 101. A laying auxiliary component 2 is installed on the concave trough 101 through the additional track 104. The laying auxiliary component 2 is used to provide support and limit the vertical arrangement of multiple optical cables.

[0027] Paving auxiliary components 2 include a base plate 201, a vertical plate 202, and an arc-shaped support plate 203;

[0028] The vertical plate 202 is fixed to the top of the base plate 201, and the arc-shaped support plate 203 is fixed to the side of the vertical plate 202;

[0029] The base plate 201 is installed on top of the mounting rail 104, and the arc-shaped support plate 203 is used to provide support for the placement of the optical cable.

[0030] A convex bracket 204 is fixed to the bottom of the base plate 201, and a screw hole 205 is provided in the middle of the top of the base plate 201, which penetrates the bottom of the convex bracket 204.

[0031] The convex bracket 204 is inserted into the inner side of the mounting rail 104 and engaged with the top of the inner wall of the screw hole 205. It is connected to the screw hole 205 by bolt 206 and passes through the screw hole 205 to press against the bottom of the inner wall of the concave groove 101 to realize the installation of the base plate 201.

[0032] Two vertical plates 202 are symmetrically arranged with the screw hole 205 as the center, and multiple vertically distributed arc-shaped support plates 203 are arranged on both sides of the vertical plate 202;

[0033] Multiple tracks 104 are evenly arranged along the transverse width of the concave groove 101;

[0034] Two lower rails 102 are symmetrically fixed at the bottom of the concave groove 101, and docking rails 103 are fixed on both sides of the outer wall of the concave groove 101.

[0035] In this embodiment, it should be noted that when the optical cable protection trough 1 is installed by the bracket, the lower rail 102 contacts the bracket, the lower rail 102 is inserted by the gasket, and the optical cable protection trough 1 is fixed by the bolt passing through the bracket and tightening it with the thread of the gasket. In addition, when two sections of optical cable protection trough 1 are connected by the connector, the optical cable protection trough 1 can be spliced ​​and fixed by the cooperation of the gasket, bolt and connecting rail 103. The lower rail 102 and connecting rail 103 are the existing structures of optical cable channels, so they will not be described in detail here.

[0036] When laying and protecting the optical cable through the optical cable protection trough 1, a small number of optical cables are laid directly on the bottom of the inner side of the concave trough 101 (it should be noted that the area where the track 104 is installed is avoided during laying). At this time, there is no need to install the laying auxiliary component 2.

[0037] When the number of optical cables to be laid exceeds the number of optical cables that can be laid flat at the bottom of the concave groove 101, the laying auxiliary component 2 can be installed on the mounting track 104 to support the excess optical cables.

[0038] By aligning the convex bracket 204 with the opening of the mounting track 104 and inserting it, and then rotating it 90 degrees, the bottom transverse part of the convex bracket 204 is engaged with the top of the inner wall of the mounting track 104. Afterwards, the bolt 206 is threaded into the screw hole 205 and tightened. The bolt 206 passes through the screw hole 205 and fits tightly against the bottom of the concave groove 101 (e.g., Figure 2 This means that a single paving auxiliary component 2 is installed, and then multiple paving auxiliary components 2 are installed along the track 104 according to the paving length of the optical cable.

[0039] Then, the excess optical cable can be inserted into the arc-shaped support plate 203. Multiple arc-shaped support plates 203 set on both sides of the vertical plate 202 can realize the vertical placement of multiple optical cables. In addition, the structure of multiple additional tracks 104 can further increase the number of optical cables that can be laid, realize the orderly arrangement and laying of more optical cables, and facilitate the management and maintenance of optical cables.

[0040] Please refer to this carefully. Figures 1-3 The bottom horizontal portion of the convex card holder 204 is perpendicular to the base plate 201. The horizontal width of the convex card holder 204 matches the width of the large-size slot of the mounting track 104. The longitudinal length of the convex card holder 204 is less than the width of the top opening of the mounting track 104.

[0041] The lateral width of the base plate 201 matches the width of the outer wall of the added track 104;

[0042] The height of the small vertical part of the convex bracket 204 matches the height of the small slot of the added track 104.

[0043] In this embodiment: by setting the longitudinal length of the convex bracket 204 to be less than the width of the top opening of the mounting track 104, the horizontal part of the bottom end of the convex bracket 204 can be inserted into the mounting track 104. After rotating 90 degrees, the horizontal part of the bottom end of the convex bracket 204 can be engaged with the bottom of the inner wall of the mounting track 104 (it should be noted that the inner groove of the mounting track 104 is convex).

[0044] In addition, when the bottom horizontal part of the convex bracket 204 is inserted into the mounting track 104, the base plate 201 fits against the top of the mounting track 104. After the bolts 206 are tightened, the structural stability of the paving auxiliary component 2 can be guaranteed.

[0045] Please refer to this carefully. Figures 1-3 The concave groove 101, lower rail 102, docking rail 103, and mounting rail 104 are integrally formed by extrusion process, while the base plate 201, vertical plate 202, arc support plate 203, and convex bracket 204 are integrally formed by injection molding process.

[0046] In this embodiment, the processing technology of the optical cable protection trough 1 is the same as that of the optical cable troughs on the market, which makes it easy to improve production based on existing equipment. The material of the laying auxiliary component 2 (except for the bolt 206) is the same as that of the optical cable protection trough 1. The laying auxiliary component 2 is integrally molded by injection molding, and its production cost is controllable, which makes it easy to promote production.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
