Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a cable bridge which is easy to install and disassemble. Background Art

[0002] Cable tray is a structural device specially used to support, manage and protect cable lines. Its frame is generally made of fire-resistant and corrosion-resistant alloy materials. With the improvement of production technology and considering the actual flexible application, cable trays are currently produced in modular form. During the production process, they are often divided into several assembly frames to achieve modular mass production and facilitate subsequent transportation, and can be assembled later.

[0003] In order to ensure the maintenance, addition or replacement of cables in the later stage, the frame connection needs to ensure that it is easy to dismantle and reinstall. At present, the market mostly adopts welding or bolting between the connection points of the two assembly frames to be connected. Although this assembly method can maintain stability, it is difficult to disassemble and assemble, and there will be welding scars and exposed bolts in the connection area, which affects the overall aesthetics of the appearance. It is now necessary to solve the technical problems of fixed connection, difficult disassembly and assembly of each assembly part, and unsightly connection parts. Utility Model Content

[0004] In order to solve the problems in the above-mentioned background technology, the utility model provides a cable tray that is easy to install and disassemble.

[0005] The solution adopted by the utility model to solve its technical problems is: an easily installed and disassembled cable tray, including a first tray frame, a second tray frame arranged on one side of the first tray frame and a connecting structure, the connecting structure including a number of fixing holes chiseled on the wall surface of the first tray frame and the second tray frame close to the connecting end and a connecting plate attached to the fixing holes, a number of fixing spring buckles adapted to the fixing holes and used for being plugged into the fixing holes to form a fixation are provided on the end surface of the connecting plate, the fixing spring buckle includes a main body, a gap is provided between the main body and the end surface of the connecting plate and the abutment portion is inclined toward the end surface to form abutment for abutting the inner wall of the tray frame.

[0006] By adopting the above technical solution, the fixing buckle on the end face of the connecting plate is inserted into the fixing holes on the wall of the first bridge frame and the second bridge frame for matching and fixing, so that the bridge frames can be assembled simply and quickly, and the assembly efficiency and flexibility can be effectively improved; and the fixing buckle is an elastic structure, which has a gap with the end face of the connecting plate and is inclined to the end face to form an abutment portion, so that after the fixing buckle is inserted into the hole, it can clamp and abut the inner wall of the bridge frame with the abutment portion to effectively prevent the bridge frame from loosening after installation, thereby improving the stability of the structure. And the connecting plate covers the connection, so that the appearance of the bridge frame can be simple and beautiful.

[0007] Furthermore, the bottom of the main body is bent outward to form an inserting portion for facilitating the fixing spring buckle to be inserted into the fixing hole.

[0008] By adopting the above technical solution, the plug-in portion formed by folding outward can guide the fixing spring buckle to be inserted into the fixing hole accurately and quickly, thereby effectively improving the assembly efficiency.

[0009] Furthermore, the connection structure also includes a support plate for preliminarily connecting the first bridge frame body and the second bridge frame body, and a plurality of fixing plugs adapted to the size of the fixing holes are provided on the end surface of the support plate.

[0010] By adopting the above technical solution, after splicing the first bridge frame and the second bridge frame at the connection where the fixing holes are provided, the fixing plugs on the support plate can be easily inserted into the fixing holes for preliminary alignment and connection, which facilitates the subsequent docking and fixing of the connecting plates and speeds up the installation.

[0011] Furthermore, the support plate extends vertically along the bottom to form a bearing portion.

[0012] By adopting the above technical solution, the bottom of the first bridge frame and the second bridge frame can be supported for auxiliary positioning, effectively preventing the frame from loosening during installation and avoiding gaps at the joints. It can also serve as a bearing structure to enhance the overall mechanical properties of the cable bridge, provide additional supporting force, and ensure the stability and durability of the bridge structure.

[0013] Furthermore, the cross-sections of the first bridge frame and the second bridge frame are both U-shaped.

[0014] By adopting the above technical solution, the first bridge frame and the second bridge frame are both set to have a U-shaped cross section, so that the two frames can be well embedded in each other during splicing, and can be tightly docked and fixed through the support plate and the connecting plate. The U-shaped cross-section design helps air flow inside the bridge, protecting the internal cables while facilitating the heat dissipation of the cables.

[0015] Furthermore, a slope is formed in the fixing hole to facilitate the assembly and disassembly of the fixing spring buckle.

[0016] By adopting the above technical solution, the slope can guide the fixing spring buckle during the process of inserting or removing it from the fixing hole, thereby improving the loading and unloading efficiency.

[0017] In summary, the beneficial effects of the utility model are:

[0018] 1.

[0030] like Figures 1 to 4 As shown, a cable bridge that is easy to install and disassemble includes a first bridge frame 1, a second bridge frame 2 arranged on one side of the first bridge frame 1 and a connecting structure 3 for connecting and installing, wherein the connecting structure 3 of this embodiment includes a number of fixing holes 33 chiseled on the wall surface of the first bridge frame 1 and the second bridge frame 2 close to the connection end and a connecting plate 31 attached to the fixing holes 33, and a number of fixing spring buckles 4 adapted to the fixing holes 33 and used for being inserted into the fixing holes 33 to form a fixation are provided on the end surface of the connecting plate 31, and the fixing spring buckle 4 includes a main body 41, a gap is provided between the main body 41 and the end surface of the connecting plate 31, and the abutment portion 43 is inclined toward the end surface to abut against the inner wall of the bridge frame.

[0031] In this embodiment, multiple rows and columns of equally spaced fixing holes 33 are formed by drilling through the wall surfaces of the first bridge frame 1 and the second bridge frame 2 to be assembled, and the connecting plate 31 fits and covers these fixing holes 33, and the fixing spring buckles 4 on the connecting plate 31 cooperate with the preset fixing holes 33 on the wall surfaces of the first bridge frame 1 and the second bridge frame 2, and the fixing spring buckles 4, by virtue of their elastic properties, realize the simple, efficient and rapid assembly between the first bridge frame 1 and the second bridge frame 2. The fixing spring buckle 4 is designed to leave a gap approximately equal to the thickness of the frame between its main body 41 and the end surface of the connecting plate 31, and the whole body is inclined to the end surface to form an abutment portion 43 at the bottom. After the fixing spring buckle 4 is inserted into the fixing hole 33, the fixing spring buckle 4 of elastic material can cooperate with the connecting plate 31 fitted on the outer wall of the first bridge frame 1 and the second bridge frame 2 to clamp the side wall of the frame, and use the abutment portion 43 to abut against the inner wall of the frame to prevent loosening. The external connecting plate 31 can cover the connection, and the color and pattern of the connecting plate 31 can be customized to maintain the aesthetics.

[0032] like Figure 2 and Figure 4 As shown, the bottom of the main body 41 of this embodiment is bent outward to form an inserting portion 42. The inserting portion 42 formed by the folded outward can guide the fixing spring buckle 4 to be inserted into the fixing hole 33 accurately and quickly, effectively improving the assembly efficiency. A slope 331 is formed in the fixing hole 33 to facilitate the disassembly of the fixing spring buckle 4. The slope 331 can guide the fixing spring buckle 4 in the process of inserting or pulling out of the fixing hole 33, thereby improving the loading and unloading efficiency.

[0033] like Figure 2 As shown, the connection structure 3 of this embodiment also includes a support plate 32 for preliminarily connecting the first bridge frame 1 and the second bridge frame 2. The end surface of the support plate 32 is provided with a plurality of fixed plugs 321 adapted to the size of the fixing holes 33. A vertically bent bearing portion 322 is provided at the corner of the support plate 32 corresponding to the first bridge frame 1 and the second bridge frame 2 to wrap the bottom surface of the bridge frame. The fixed plugs 321 on the support plate 32 that can be easily inserted into the fixing holes 33 can be used for preliminary alignment and connection, which is convenient for the subsequent docking and fixing of the connecting plate 31 and speeding up the installation speed; and the lower half of the connecting plate 31 is folded corresponding to the upper half to cover the gap on the wall of the mounting plate, and a hole is also chiseled at the mounting plate corresponding to the fixed spring buckle 4 to facilitate the fixed spring buckle 4 to pass through the support plate 32 and be installed and fixed with the bridge frame. In this embodiment, the assembly process of the first bridge frame 1 and the second bridge frame 2 is as follows: after splicing the connecting ends of the first bridge frame 1 and the second bridge frame 2, first use the fixing plug block 321 on the support plate 32 to be inserted into the fixing hole 33 to preliminarily assemble the first bridge frame 1 and the second bridge frame 2; then align the plug-in portion 42 of the fixing spring buckle 4 of the connecting plate 31 with the fixing hole 33 and insert it. After the plug-in portion 42 is inserted, slide the connecting plate 31 down so that the fixing spring buckle 4 completely enters the fixing hole 33 and abuts against the inner wall of the frame to fix it.

[0034] like Figure 1 and Figure 3 As shown, the cross-sections of the first bridge frame 1 and the second bridge frame 2 of this embodiment are both in the shape of a U-shape. By setting the cross-sections of the first bridge frame 1 and the second bridge frame 2 to be U-shaped, the two frames can be well fitted with each other during splicing, and can be tightly docked and fixed through the support plate 32 and the connecting plate 31. The U-shaped cross-section design is conducive to the circulation of air inside the bridge, which effectively shields and protects the internal cables while greatly enhancing the heat dissipation performance of the cables.

[0035] In summary, the beneficial effects of this embodiment are as follows: in this embodiment, the fixing spring buckles 4 on the connecting plate 31 are respectively inserted into the corresponding fixing holes 33 on the side walls of the U-shaped bridge frame, so that the first bridge frame 1 and the second bridge frame 2 to be assembled can be quickly installed and fixed. The operation is simple and the disassembly and assembly process does not damage the bridge frame, and the bridge frame can be repeatedly disassembled and installed. Then, the main body 41 of the fixing spring buckle 4 is tilted to form an abutment portion 43, which can ensure the firmness of the installation, and the bottom of the main body 41 is bent outward to form an insertion portion 42, which can guide the fixing spring buckle 4 to be accurately and quickly inserted into the fixing hole 33, effectively improving the assembly efficiency. In addition, a support plate 32 is provided, which can be used for preliminary alignment and connection of the bridge frame, and can provide stable support and positioning for the bridge frame during the installation process.
