Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a bridge cover fixing structure. Background Art

[0002] Cable trays are widely used in project construction. Existing cable tray covers are fixed with self-tapping screws that are drilled directly from the outside of the cover through the folded edge of the cable tray. However, during long-term use, the self-tapping screws will vibrate due to the cable tray, causing the holes in the cable tray where the self-tapping screws are fixed to deform, making the self-tapping screws unstable. At the same time, the cover needs to be disassembled for cable maintenance. After multiple self-tapping screw fixes, the holes expand, affecting the fixing structure and the strength of the cable tray. Utility Model Content

[0020] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0021] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0022] Example 1

[0023] like Figures 1-2 As shown:

[0024] A bridge frame 1 cover plate 2 fixing structure, comprising

[0025] Bridge 1; the bridge 1 is configured as a U-shaped frame structure;

[0026] Cover plate 2; the cover plate 2 is buckled at the upper opening of the bridge frame 1;

[0027] The bridge frame 1 and the cover plate 2 are fixedly connected via a connecting piece 3;

[0028] The ends of both sides of the bridge frame 1 are bent inwards to form a bent portion 11; the outer sides of the bent portion 11 are rounded;

[0029] The cover plate 2 is provided with a buckling portion 21 extending vertically downward at both ends; the buckling portion 21 is bent inwardly to form a two-layer structure. Specifically, the buckling degree of the interference fit can be increased through the two-layer structure, and the two-layer structure can also increase the wear resistance to avoid failure of the fit due to wear.

[0030] Mounting holes 4 are provided at corresponding positions on both sides of the bridge frame 1 and the cover plate 2. The connector 3 is provided on the mounting hole 4. The connector 3 includes a mounting portion 31, a fixing ring 32 and a bolt 33; the fixing ring 32 is provided at the end of the mounting portion 31; a threaded hole 311 is provided at the center of the mounting portion 31; the bolt 33 cooperates with the threaded hole 311 to fix the bridge frame 1 and the cover plate 2. The outer wall diameter of the mounting portion 31 is arranged from small to large and then from large to small from top to bottom.

[0031] By changing the diameter of the outer wall of the mounting portion 31, the maximum outer diameter can be locked by itself after being pressed into the mounting hole 4. At this time, it is locked by the bolt 33 to prevent the connector 3 from falling due to shaking.

[0032] The inner wall of the bridge frame 1 is also provided with a fixing member 5 for fixing and installing cables.

[0033] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
