However, in actual engineering, the layout and quantity of cable are indefinite, so that the bridge with suitable width cannot be selected due to installation site environment, cable demand and other reasons during installation, and the fixed bridge also cannot meet the flexible demand when needing adjustment due to equipment updating, line expansion or environment change in later period. SUMMARY

[0003] The utility model discloses to the defects and insufficiency of prior art, provide a kind of adjustable cable bridge of reasonable design, it can solve the above-mentioned defects.

[0004] To achieve the above object, the utility model adopts the following technical scheme: it contains the bridge unit of "L" shape consisting of bottom plate and side plate, the number of bridge unit is not less than two, and bridge unit is connected by bolt between each other, the front end of each bridge unit bottom surface is opened with several front screw holes and adjusting holes, and several rear screw holes are opened in the position of bridge unit bottom surface rear end, and bridge unit is connected by bolt between each other in front screw hole and adjusting hole or rear screw hole and adjusting hole.

[0005] Preferably, the distance between adjacent front screw holes and the distance between adjacent adjusting holes are equal, and the front screw holes and the adjusting holes are arranged along a straight line.

[0006] Preferably, the number of front screw holes and adjusting holes is equal, and the distance between front screw holes and adjusting holes located at both ends of bridge unit and the edge of both ends of bridge unit is equal.

[0007] Preferably, the adjusting hole is a round rectangular through hole.

[0008] Preferably, the rear screw hole is located directly behind the adjusting hole.

[0009] After adopting the above structure, the utility model has the beneficial effects that:

[0010] The utility model has simple structure, by designing adjusting hole and front screw hole and rear screw hole, only single bridge unit needs to be produced, and it can be connected to form bridge with different length and width by adjusting the number of bridge unit and the distance between bridge unit. Figures 2-3The components can be assembled relative to each other using unit two and unit three, or they can be added unidirectionally using unit one and unit two. Each cable tray unit can adjust its position and change the width of its internal slot during installation to adapt to different needs, offering high flexibility. The width can also be adjusted later. Attached Figure Description

[0016] 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.

[0017] See Figures 1-2 As shown, it includes an "L"-shaped cable tray unit 1 composed of a base plate and side plates. There are no fewer than two cable tray units 1, and the cable tray units 1 are connected by bolts. Each cable tray unit 1 has several front screw holes 3 and adjustment holes 4 at the front end of its bottom surface, and several rear screw holes 2 at the rear end of its bottom surface. The cable tray units 1 are connected by bolts between the front screw holes 3 and adjustment holes 4 or between the rear screw holes 2 and adjustment holes 4.

[0018] The distance between adjacent front screw holes 3 and the distance between adjacent adjustment holes 4 are equal. The front screw holes 3 and adjustment holes 4 are staggered along a straight line. The number of front screw holes 3 and adjustment holes 4 is equal. The distance between the front screw holes 3 and adjustment holes 4 located at both ends of the cable tray unit 1 and the edges of both ends of the cable tray unit 1 is equal. Therefore, after any adjustment hole 4 is rotated 180° around the centerline of the cable tray unit 1, it will overlap with the position of the front screw hole 3.

[0019] The adjustment hole 4 is a rounded rectangular through hole; the rear screw holes 2 are all located directly behind the adjustment hole 4.

[0020] During assembly, such as Figures 2-3 As shown, unit components A and B are arranged in parallel, while unit components B and C are arranged opposite each other. That is, unit component C can be rotated 180° from the angle of unit component B to the state of unit component C. After flipping, the front screw hole 3 of unit component C is aligned with the adjustment hole 4 of unit component B. Therefore, by placing unit component C above or below unit component B, and aligning the front screw hole 3 of unit component C with the adjustment hole 4 of unit component B, bolts and washers can be installed for connection. At the same time, according to the required size, unit components B and C can be pulled to adjust the distance between them. After changing the size of the internal groove, the bolts can be tightened to achieve fixation.

[0021] When it is necessary to increase the number of horizontal cable trays, simply place unit A on the lower rear side of unit B, align the front screw hole 3 of unit B with the adjustment hole 4 of unit A, insert the bolts, adjust the size slightly, and then tighten the bolts to fix it and complete the assembly.

[0022] According to the size requirements, repeat the above installation method to assemble the required cable tray;

[0023] When subsequent size adjustments are needed, the cables can be suspended using temporary devices, and the bolts can be loosened to adjust the installation position of each cable tray unit, thereby adjusting the overall or partial width of the cable tray.

[0024] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
