Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a quick-connect buckle structure for a trackside cable tray. Background Technology

[0002] Cable trays are rigid structural systems used to support, protect, and manage cables and wires. They are widely used in building interiors, industrial facilities, and other places to ensure the safety, aesthetics, and reliability of cable wiring.

[0003] In rail transit, electrified railways, or urban subway systems, cable trays are widely used as key facilities for supporting and protecting cables in trackside cable laying projects.

[0004] Traditional cable tray connections mainly rely on bolt fixing or welding. Bolt connections require tightening each bolt individually, while welding requires specialized equipment and operators, resulting in long construction times and failing to meet the rapid construction needs of the rail transit sector. Furthermore, bolts are prone to rust or loosening, making disassembly difficult during later maintenance. Welding, on the other hand, provides a permanent connection, but requires cutting when adjusting or replacing the cable tray, damaging the original structure. To address these problems and shortcomings, a quick-connect snap-fit ​​structure for trackside cable trays is urgently needed. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a quick-connect buckle structure for cable trays along railway tracks. This addresses the limitations of existing cable tray connection methods, which mainly rely on bolt fixing or welding. Bolt connections require individual tightening, while welding requires specialized equipment and operators, resulting in long construction times and failing to meet the rapid construction needs of the rail transit sector. Furthermore, bolts are prone to corrosion or loosening, making disassembly difficult during later maintenance. Welding, on the other hand, provides a permanent connection, but requires cutting to adjust or replace the cable tray, thus damaging the original structure.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A quick-connect buckle structure for a trackside cable tray includes: a cable tray body, with grooves on both sides of the cable tray body, and a positioning plate rotatably connected to the inner wall of the grooves; a square groove on the outer wall of the positioning plate, a circular groove on the inner wall of the square groove, a spring fixedly mounted on the inner wall of the circular groove, a connecting block fixedly mounted on the end of the spring away from the circular groove, a locking block fixedly mounted on the side of the connecting block away from the spring, a through groove on the outer wall of the positioning plate, a movable plate fixedly mounted on the outer wall of the connecting block, the movable plate penetrating the through groove, and a fixing pin fixedly mounted on the side of the positioning plate away from the square groove.

[0008] Preferably, the top of the cable tray body is provided with a sliding groove, and a cover plate is slidably connected to the inner wall of the sliding groove.

[0009] Preferably, a partition is fixedly installed at the bottom of the inner wall of the cable tray body, and the number of partitions is multiple sets, including at least five sets evenly distributed at the bottom of the inner wall of the cable tray body.

[0010] Preferably, a folded cloth is fixedly fitted to the inner wall of the through groove, and the side of the folded cloth away from the through groove is fixedly connected to the movable plate.

[0011] Preferably, the cross-sectional shape of the card block is a right trapezoid, and the hypotenuse of the card block is located on the side away from the fixing pin.

[0012] Preferably, the number of springs, connecting blocks, locking blocks, moving plates and fixing pins is two sets, and the two sets of springs, connecting blocks, locking blocks, moving plates and fixing pins are symmetrically distributed on both sides of the positioning plate.

[0013] Preferably, the number of positioning plates is four sets, and the four sets of positioning plates are evenly distributed at the four corners of the cable tray body.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] 1. In the above solution, by rotating the positioning plate on one side of the cable tray body 180 degrees, the inner fixing pin is turned out. Then, the fixing pin is aligned with the square groove of the positioning plate on the other cable tray body and inserted. When the locking block is pressed by the fixing pin, the locking block and the connecting block move into the depth of the circular groove. When the fixing pin is fully inserted into the square groove, the locking block loses its pressing force. The connecting block and the locking block are pushed towards the fixing pin by the spring and locked with the fixing pin, thus completing the connection and fixing of the two sets of cable tray bodies. When it is necessary to disassemble the two sets of cable tray bodies, it is only necessary to press the moving plate to push the connecting block and the locking block into the depth of the circular groove, so that the locking block and the fixing pin are separated, and the two sets of cable tray bodies can be separated. This is beneficial to improving the convenience of disassembling and assembling the two sets of cable tray bodies, thereby meeting the needs of rapid construction in the rail transit field.

[0016] 2. In the above scheme, by setting up partitions and limiting the number of partitions, it is beneficial to classify and store cables when placing them in the cable tray body, thereby preventing the cables from getting tangled together and affecting their use. Attached Figure Description

Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0029] like Figure 1 , Figure 4 and Figure 5As shown, an embodiment of this utility model provides a quick-connect buckle structure for a trackside cable tray, comprising: a cable tray body 1, with grooves 11 on both sides of the cable tray body 1, and a positioning plate 12 rotatably connected to the inner wall of the grooves 11; a square groove 1201 is formed on the outer wall of the positioning plate 12, and a circular groove 1202 is formed on the inner wall of the square groove 1201; a spring 1203 providing elastic force is fixedly installed on the inner wall of the circular groove 1202; a connecting block 1204 is fixedly installed on the end of the spring 1203 away from the circular groove 1202; a locking block 1205 is fixedly installed on the side of the connecting block 1204 away from the spring 1203; a through groove 1206 is formed on the outer wall of the positioning plate 12; and a through groove 1205 is formed on the outer side of the connecting block 1204. A movable plate 1207 is fixedly mounted on the wall, and the movable plate 1207 passes through the through groove 1206. A fixing pin 1208 is fixedly mounted on the side of the positioning plate 12 away from the square groove 1201. There are two sets of springs 1203, connecting blocks 1204, locking blocks 1205, movable plates 1207 and fixing pins 1208. The two sets of springs 1203, connecting blocks 1204, locking blocks 1205, movable plates 1207 and fixing pins 1208 are symmetrically distributed on both sides of the positioning plate 12. By limiting the number and position of springs 1203, connecting blocks 1204, locking blocks 1205, movable plates 1207 and fixing pins 1208, it is beneficial to improve the firmness of the connection between the two sets of cable tray bodies 1.

[0030] like Figure 3 and Figure 5 As shown, a groove 13 is provided on the top of the cable tray body 1, and a cover plate 14 is slidably connected to the inner wall of the groove 13. By setting the groove 13 and the cover plate 14, it is beneficial to cover the top of the cable tray body 1, thereby improving the protection effect on the cable.

[0031] like Figure 2 and Figure 3 As shown, a partition 15 is fixedly installed at the bottom of the inner wall of the cable tray body 1. The number of partitions 15 is multiple, including at least five groups evenly distributed at the bottom of the inner wall of the cable tray body 1. By setting the partitions 15 and limiting the number of partitions 15, it is beneficial to classify and store the cables when placing them in the cable tray body 1, thereby preventing the cables from getting tangled together and affecting the use of the cables.

[0032] like Figure 3 and Figure 5 As shown, a folded cloth 1209 is fixedly fitted on the inner wall of the through groove 1206. The side of the folded cloth 1209 away from the through groove 1206 is fixedly connected to the movable plate 1207. By setting the folded cloth 1209, it is beneficial to seal the through groove 1206 through the folded cloth 1209, thereby preventing external dust and impurities from clogging the through groove 1206, and thus ensuring the normal use of the movable plate 1207.

[0033] like Figure 2 and Figure 4 As shown, the cross-sectional shape of the locking block 1205 is a right trapezoid, and the hypotenuse of the locking block 1205 is located on the side away from the fixing pin 1208. By limiting the locking block 1205, it is beneficial to improve the smoothness of the locking pin 1208 and the locking block 1205 when they are engaged.

[0034] like Figure 2 and Figure 3 As shown, there are four sets of positioning plates 12, and the four sets of positioning plates 12 are evenly distributed at the four corners of the cable tray body 1. By limiting the number and position of the positioning plates 12, it is beneficial to improve the stability of the connection and fixation between the cable tray body 1 and the cable tray body 1, and ensure the protection effect of the cable.

[0035] The technical solution provided by this utility model, during operation, involves rotating the positioning plate 12 on one side of the cable tray body 1 by 180 degrees to turn out the inner fixing pin 1208. Then, the fixing pin 1208 is aligned with and inserted into the square groove 1201 of the positioning plate 12 on the other cable tray body 1. When the locking block 1205 is pressed by the fixing pin 1208, the locking block 1205 and the connecting block 1204 move deeper into the circular groove 1202. When the fixing pin 1208 is fully inserted into the square groove 1201, the locking block 1205 loses its pressing force and springs back to its original position. Spring 1203 pushes connecting block 1204 and locking block 1205 toward fixing pin 1208 and engages with fixing pin 1208 to complete the connection and fixation of the two sets of cable tray bodies 1. When it is necessary to disassemble the two sets of cable tray bodies 1, simply press moving plate 1207 to push connecting block 1204 and locking block 1205 into the depth of circular groove 1202, so that locking block 1205 separates from fixing pin 1208, and the two sets of cable tray bodies 1 can be separated, which helps to improve the convenience of disassembling and assembling the two sets of cable tray bodies 1.

[0036] By setting up partitions 15 and limiting the number of partitions 15, it is beneficial to classify and store cables when placing them in the cable tray body 1, thereby preventing the cables from getting tangled together and affecting their use.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
