[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention facilitates rapid assembly through the combination of movable plates, combination plates, and connecting ropes. No tools are required during installation, effectively reducing installation and disassembly time. A support saddle provides support for the top cable tray frame. During installation, the movable block is pulled downwards using a handle. During this downward movement, two sets of adjusting ropes pull the movable plate along the guide wheels, causing it to retract towards the center of the support saddle. The combination plate is then assembled with the fixed plate. After assembly, releasing the handle causes the support spring to push the movable plate outwards along the limiting guide rod. This outward extension pushes the positioning cone into the inner side of the cone groove, which restricts the assembled cable tray frame. This method enables rapid assembly and disassembly without the need for tools, effectively reducing the difficulty of installation and disassembly.

[0019] This invention, through the combination of movable columns, a combination turntable, and a combination frame, facilitates easy assembly and allows for adjustment to seal the side gaps of the cable tray. During assembly, the movable column is inserted into the movable groove of the combination turntable. After assembly, the movable plate is pushed outward under the action of the support spring. During this outward expansion, the movable column expands synchronously. Since the movable column is embedded in the inner side of the movable groove, it slides along the inner side of the groove during expansion, guiding the combination turntable to rotate along the inner side of the groove. Simultaneously, the rotation, through the cooperation of the push plate and the limiting shaft, pushes the combination frame to slide along the inner side of the cable tray frame. During this sliding process, the gap in the middle of the two parts is sealed, thereby increasing the stability of the assembly and reducing the presence of gaps, thus reducing the probability of dust entering.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1 to 7As shown, the present invention provides a cable tray that is easy to assemble, including a cable tray frame 1. Several sets of support saddles 3 are provided at the bottom of the cable tray frame 1, and four sets of fixing plates 303 are fixedly installed on the top of the upper end of the support saddles 3. Three sets of limiting guide rods 304 are fixedly installed between two sets of fixing plates 303. A support spring 305 is provided on the outer side of the middle limiting guide rod 304. Movable plates 6 are movably installed at both ends of the support spring 305. An adjusting rope 601 is installed in the middle of the side of the movable plate 6 near the support spring 305, and a movable block 403 is installed at the end of the adjusting rope 601. Three sets of positioning cones 603 are installed on the side of the movable plate 6 away from the adjusting rope 601. A combination plate 105 is installed at the bottom of both ends of the cable tray frame 1, and three sets of conical grooves 106 are respectively opened on the side of the combination plate 105 away from the middle. The conical grooves 106 and the positioning cones 603 are movably combined.

[0030] The above solution provides support for the top cable tray frame 1 by using the support saddle 3. During installation, the movable block 403 needs to be pulled down using the handle, and then the combination plate 105 and the fixed plate 303 are combined. After the combination, the pull handle 4 is released, and the support spring 305 will push the movable plate 6 outward along the limit guide rod 304. After outward, it will push the positioning cone 603 to be embedded in the inner side of the cone groove 106. The cone groove 106 can restrict the spliced ​​cable tray frame 1. This method can achieve rapid assembly and splicing, and the installation and disassembly difficulty can be effectively reduced without the use of tools.

[0031] like Figures 1-4 As shown, two sets of combination grooves 101 are respectively opened on the inner side of both ends of the cable tray frame 1, and six sets of positioning columns 102 are fixedly installed on the top of the cable tray frame 1.

[0032] The top of the cable tray frame 1 is movably spliced ​​with a dust cover 103, and the inner side of the dust cover 103 is provided with six sets of positioning holes 104, which are movably spliced ​​with the positioning posts 102.

[0033] The inner side of the combination groove 101 is movably spliced ​​with a limiting plate 201, and a combination turntable 2 is fixedly installed in the middle of the limiting plate 201. A strip-shaped movable groove 202 is opened on the combination turntable 2.

[0034] A limiting shaft 203 is fixedly installed on the combination turntable 2, and a push plate 204 is movably arranged on the outer side of the limiting shaft 203. Another set of limiting shafts 203 is movably arranged on the inner side of the end of the push plate 204, and a combination frame 205 is movably installed on the outer side of the other set of limiting shafts 203. The combination frame 205 is movably arranged on the inner side of the cable tray frame 1 near the end of the combination turntable 2.

[0035] Using the above solution: the cable tray frame 1 needs to be fixed to the wall with bolts. The combination groove 101 is a circular groove that allows the limiting plate 201 to rotate, assisting the combination turntable 2 in rotational adjustment. The positioning column 102 can restrict the dust cover 103 that is spliced ​​and installed. When the dust cover 103 and the positioning column 102 are spliced, a certain amount of pressure needs to be applied. When the combination turntable 2 rotates, it can facilitate the rotation and adjustment of the installed limiting shaft 203. At the same time, the movable splicing push plate 204 can rotate and adjust the angle on the limiting shaft 203, and can push the combination frame 205 along the bridge. The inner side of the frame 1 is slidably adjustable. A limiting guide rod 304 with a support spring 305 is installed in the middle area of ​​the fixed plate 303 and the support saddle 3. The limiting guide rod 304 is lower than the other two sets of limiting guide rods 304. Several sets of bolt holes are opened through the side of the cable tray frame 1. The bolt holes are used to fix the support saddle 3 to the wall through the bolt structure. The combined frame 205 has a slot on the side facing the push plate 204. The push plate 204 is movably set inside the slot of the combined frame 205 through the limiting shaft 203. When adjusting, the push plate 204 can rotate along the limiting shaft 203 inside the slot.

[0036] like Figure 5 and Figure 6 As shown, two sets of diagonal bracing rods 301 are welded and installed on the inner side of the supporting saddle 3, and two sets of stop blocks 302 are fixedly installed on the top of both ends of the supporting saddle 3. The stop blocks 302 are located between the two sets of movable plates 6, and a fixed bracket 501 is installed on the inner side of the upper end of the supporting saddle 3.

[0037] A limiting frame 401 is movably installed on the outer side of the movable block 403, and the limiting frame 401 is fixedly installed on the inner side of the supporting saddle 3. Two sets of sliding column grooves 402 are opened on the inner side of the limiting frame 401, and the sliding column grooves 402 match the columnar structure on the side of the movable block 403.

[0038] A connecting rope 404 is installed at the bottom of the movable block 403, and a pull handle 4 is fixedly installed at the end of the connecting rope 404 away from the movable block 403.

[0039] Using the above scheme: the diagonal brace 301 can increase the stability of the supporting saddle 3 by welding; the stop block 302 can block the movable plate 6 to avoid excessive compression of the supporting spring 305; the connecting rope 404 can connect the movable block 403 and the pull handle 4. After connection, the pull handle 4 can be used to control the movable block 403 and the structure connected to the movable block 403 to move along the preset movement direction; the fixed bracket 501 can be fixed to the supporting saddle 3 by welding to keep the guide structure on one side restricted.

[0040] like Figure 7As shown, a reinforcing corner seat 502 is welded to the inner corner of the fixed bracket 501, and two sets of fixed rods 503 are welded to the upper end of the fixed bracket 501 near the adjusting rope 601. Two sets of curved brackets 504 are installed at the ends of the fixed rods 503, and a guide wheel 5 is movably connected to the middle of the curved bracket 504 through a rotating shaft. A connecting rod 505 is fixedly installed at the middle of the lower end of the two sets of curved brackets 504, and the end of the connecting rod 505 is welded to the lower end of the fixed bracket 501.

[0041] The bottom of the movable plate 6 has two sets of protrusions, and the inner side of the movable plate 6 has six sets of through holes 602. The through holes 602 are movably installed with the limiting guide rod 304. Two sets of movable columns 604 are fixedly installed on the top of the movable plate 6 near the combined turntable 2, and the movable columns 604 are movably set inside the movable groove 202.

[0042] The above solution is adopted: the reinforcement of the corner bracket 502 is increased by welding to increase the strength of the fixed bracket 501. The fixed rod 503 and the connecting rod 505 can restrict the curved bracket 504 and keep the curved bracket 504 stable in limiting the guide wheel 5. The guide wheel 5 can guide the adjusting rope 601. The through hole 602 can be combined with the limiting guide rod 304 to make the movable plate 6 slide and adjust stably along the limiting guide rod 304. The movable column 604 can drive the combined turntable 2 to rotate and adjust. The guide wheel 5 at the upper end of the curved bracket 504 is horizontal and the guide wheel 5 at the lower end of the curved bracket 504 is vertical. The adjusting rope 601 is movably set in the gap inside the guide wheel 5.

[0043] The working principle and usage process of this invention are as follows: First, the support saddles 3 need to be installed equidistantly on the wall surface according to requirements. After approaching the wall, the support saddles 3 are fixed using bolts. Then, the operator needs to grip and pull the handle 4 and provide downward force. Under the action of the pulling force, the connecting rope 404 will drive the movable block 403 to slide downward along the inner side of the limiting frame 401. During the sliding process, the adjusting rope 601 on the right side will move downward synchronously. Since the length of the adjusting rope is fixed, during the pulling process, the adjusting rope 601 will move along the inner side of the guide wheel 5. The end will pull the movable plate 6 to move along the limiting guide rod 304 towards the middle area of ​​the support saddle 3 until the movable plate 6 contacts the stop block 302 structure. Then, the operator places the ends of the two sets of cable tray frames 1 on top of the support saddle 3. During the placement process, it is necessary to ensure that the bottom combination plate 105 is spliced ​​in the middle area of ​​the fixed plate 303. During the splicing process, it is necessary to ensure that the movable column 60 4 is embedded in the inner side of the movable groove 202. Then, the staff can directly release the pull handle 4. Without the tension, the support spring 305 will push the movable plate 6 to slide outward along the limit guide rod 304. During the outward extension, the positioning cone 603 installed on the outer side will be embedded in the inner side of the cone groove 106. The middle cable tray frame 1 can be locked by the two sets of support saddles 3. During the outward extension of the movable plate 6, the top movable column 604 will extend outward simultaneously. During the movement, the combined turntable 2 will be pushed to rotate along the inner side of the combined groove 101. During the rotation, the limit shaft 203 on the other side will be pushed to move. Using the limit shaft 203 and the push plate 204, the combined frame 205 will be pushed to slide along the inner side of the cable tray frame 1. The sliding will be limited to the gap between the cable tray frames 1. Finally, the cables that need to be connected are set inside the cable tray frame 1. Finally, the positioning hole 104 of the dust cover 103 and the positioning column 102 are combined and spliced.
