Detailed Implementation

[0031] 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.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: a quick connection structure for a cable tray, including a cable tray body 1, with convenient connection components 2 arranged on the left and right sides of the cable tray body 1. The convenient connection components 2 include mating side plates 201 welded to the left and right ends of the cable tray body 1, and a connecting bottom groove 202 is opened at the bottom end of the cable tray body 1. A connecting plate 203 is arranged on the outside of the connecting bottom groove 202.

[0033] Furthermore, the interior of the mating plate 201 is hollow, and a release plate 209 is movably connected to the inner side of the mating plate 201. A connecting pressure plate 210 is welded to the top of the release plate 209. The surface of the release plate 209 has an undulating structure. When it is necessary to separate the two cable tray bodies 1, the connecting pressure plate 210 can be manually pressed. The connecting pressure plate 210 is forced to drive the release plate 209 to descend inside the mating plate 201. During the descent, the release plate 209 squeezes the fixing pin 207, causing the fixing pin 207 to retract into the connecting slot 206. At this time, the mating plate 201 can be pulled out from the connecting slot 206 to complete the disassembly work, which facilitates the quick disassembly of the cable tray body 1 by the staff.

[0034] Furthermore, an anti-detachment pad 211 is installed at the top of the mating edge plate 201. The anti-detachment pad 211 is made of rubber and fits tightly with the connecting pressure plate 210. Through the friction between the connecting pressure plate 210 and the anti-detachment pad 211, the connecting pressure plate 210 can be limited to prevent it from automatically descending when no force is applied, thus ensuring the stability of the cable tray body 1 connection.

[0035] Furthermore, connecting plates 204 are welded to both ends of the connecting plate 203. The connecting plates 204 and the connecting bottom groove 202 are connected by a slot. During installation, the connecting plates 204 are inserted into the connecting plates 204 at the bottom of the cable tray body 1. Then, the cable tray body 1 that needs to be installed is inserted into the other end of the connecting plates 204. Thus, the cable tray body 1 is connected through the connecting plates 204, and the connecting plates 204 can also support the cable tray body 1, improving the stability of the connection of the cable tray body 1.

[0036] Furthermore, a connecting groove 206 is welded to the outer side of the connecting plate 203. The connecting groove 206 and the mating side plate 201 are connected by a groove. The inner width of the connecting groove 206 is the same as the thickness of the mating side plate 201. The mating side plate 201 and the connecting groove 206 fit tightly together. During installation, the mating side plate 201 is inserted into the connecting groove 206 together, so that the mating side plate 201 and the connecting groove 206 fit tightly together, which improves the tightness of the connection of the cable tray body 1 and avoids shaking or falling off during use.

[0037] Furthermore, a fixing pin 207 is installed inside the connecting slot 206, and a compression spring 208 is installed inside the fixing pin 207. The compression spring 208 is fixedly connected to the connecting slot 206. There are four sets of fixing pins 207. The surface of the mating plate 201 has slots corresponding to the fixing pins 207. The edge of the mating plate 201 is beveled. During the connection process between the mating plate 201 and the connecting slot 206, the fixing pin 207 is inserted into the slot on the surface of the mating plate 201, thereby stabilizing the mating plate 201 in the connecting slot 206 and preventing the mating plate 201 from falling off. The compression spring 208 supports the fixing pin 207, ensuring the stability of the connection of the cable tray body 1.

[0038] Furthermore, a fixing bolt 205 is threadedly connected to the bottom end of the connecting plate 204. The fixing bolt 205 passes through the connecting plate 204 and connects to the cable tray body 1. After the cable tray body 1 is connected, the fixing bolt 205 can be screwed on from the bottom end of the connecting plate 204. The fixing bolt 205 securely fixes the connecting plate 204 to the cable tray body 1, preventing the connecting plate 204 from falling off or shaking during use, and ensuring the stability of the cable tray body 1 during long-term use.

[0039] Working principle: In use, insert the connecting plate 204 into the connecting plate 204 at the bottom of the cable tray body 1. Then, insert the cable tray body 1 to be installed into the other end of the connecting plate 204, thereby connecting the cable tray body 1 through the connecting plate 204. At the same time, snap the mating edge plate 201 into the connecting slot 206, so that the mating edge plate 201 and the connecting slot 206 fit tightly. At this time, the fixing pin 207, under the elastic force of the compression spring 208, snaps into the slot on the surface of the mating edge plate 201, limiting the mating edge plate 201, thereby completing the quick connection of the cable tray body 1. After the cable tray body 1 is connected, the fixing bolt 205 can be screwed on from the bottom of the connecting plate 204. The connecting plate 204 is securely fixed to the cable tray body 1 by fixing bolts 205 to prevent it from falling off or shaking during use. When it is necessary to disassemble the cable tray body 1, the fixing bolts 205 are removed from the connecting plate 204, and then the connecting pressure plate 210 is manually pressed. The connecting pressure plate 210 is forced to release the plate 209, which descends inside the mating side plate 201. During the descent, the release plate 209 presses the fixing pin 207, causing the fixing pin 207 to retract into the connecting slot 206. At this time, the mating side plate 201 can be pulled out from the connecting slot 206, completing the disassembly. This completes the use of a quick connection structure for cable trays.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
