[0002] During cable laying, cable trays are often used to facilitate cable arrangement and enhance cable protection. Cable trays are divided into trough type, tray type, ladder type, and mesh type structures, and are composed of supports, brackets, and installation accessories. Cable trays inside buildings can be erected independently or laid on various building (structure) and pipe rack supports. They should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also used.

[0003] Inadequacies of existing technology: Existing cable trays are mostly installed by bolting together and fixing the various components, which is time-consuming and labor-intensive. In addition, the brackets and supports take up a lot of space and are inconvenient to transport and store. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an assembled cable tray to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembled cable tray, including a protective plate mechanism, and further including a splicing mechanism and a support structure. The side of the support structure is movably connected to the inner side wall of the protective plate mechanism, and the support structure provides support. The inner side wall of the splicing mechanism is movably connected to the side of the protective plate mechanism, and adjacent protective plate mechanisms and support structures are spliced ​​and fixed by the splicing mechanism. The splicing mechanism includes a frame, and a splicing column is fixedly connected to the side of the frame. The support structure includes a support beam, and splicing grooves are provided at both ends of the support beam. The side of the splicing groove is movably connected to the side of the splicing column. The protective plate mechanism includes a side plate, and an installation groove is provided on the side of the support beam. The side of the installation groove is movably connected to the side of the side plate.

[0006] Furthermore, a second mounting hole is provided on the side of the splicing column, a return spring is fixedly connected to the bottom end of the second mounting hole, a fixing pin is fixedly connected to the top end of the return spring, and a fixing hole is provided on the side of the splicing groove corresponding to the position of the fixing pin.

[0007] Furthermore, the side of the fixing pin is provided with a bevel, and the side of the splicing column is provided with a rounded corner.

[0008] Furthermore, a first mounting hole is provided at the bottom end of the second mounting hole, an electromagnet is fixedly connected to the side of the first mounting hole, a connecting rod is fixedly connected to the bottom end of the fixing pin, and an iron plate is fixedly connected to the bottom end of the connecting rod.

[0009] Furthermore, a fixing block is fixedly connected to the side of the frame, and a through hole is provided at the top of the fixing block.

[0010] Furthermore, the inner side wall of the frame is provided with a placement groove, the bottom end of the placement groove is movably connected to the bottom end of the side plate, and the side of the side plate is provided with a locking groove.

[0011] Furthermore, the inner side wall of the supporting beam is movably connected to the top plate, the side structure of the top plate is the same as that of the side plate, and the top of the top plate is movably connected to an inspection door via a hinge.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. The cable tray in this utility model is assembled through a column-shaped support frame, a plate-shaped protective plate mechanism, and a short splicing mechanism. During assembly, three side plates and one top plate are inserted into the mounting slots on the sides of the four support beams to form a rectangular cable laying frame. The splicing columns on the side of the frame are inserted into the splicing slots on the side of the support beams to fix the support beams, thereby fixing adjacent support beams and assembling the cable tray.

[0014] 2. When assembling the splicing mechanism and support structure of this utility model, the splicing column on the side of the frame is inserted into the splicing groove on the side of the support beam, and the inclined surface contacts the side of the fixing hole, thereby pushing the fixing pin into the second mounting hole. When the fixing pin moves to the position of the fixing hole, the return spring pushes the fixing pin into the fixing hole, thereby fixing the splicing column in the fixing hole, realizing the fixation of the adjacent support beam. When the cable tray needs to be disassembled, the electromagnet is energized to generate magnetic force, thereby generating attraction force on the iron plate, causing the connecting rod to drive the fixing pin to move out of the fixing hole and into the second mounting hole, which facilitates the removal of the splicing column from the fixing hole. The operation is simple and helps to improve work efficiency. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The assembled cable tray involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1 to 6This utility model provides an assembled cable tray, including a protective plate mechanism 1, a splicing mechanism 2, and a support structure 3. The side of the support structure 3 is movably connected to the inner side wall of the protective plate mechanism 1, and the support structure 3 provides support. The inner side wall of the splicing mechanism 2 is movably connected to the side of the protective plate mechanism 1, and adjacent protective plate mechanisms 1 and support structures 3 are spliced ​​and fixed by the splicing mechanism 2. The splicing mechanism 2 includes a frame 201, and splicing columns 202 are fixedly connected to the side of the frame 201. The support structure 3 includes a support beam 301, and splicing grooves 302 are opened at both ends of the support beam 301. The side of the splicing groove 302 is movably connected to the side of the splicing column 202. Component 1 includes side plates 101 and top plates 102. The side of the support beam 301 is provided with a mounting groove 304. The side of the mounting groove 304 is movably connected to the side of the side plate 101. According to the usage requirements, an appropriate number of protective plate mechanisms 1, splicing mechanisms 2 and support structures 3 are selected. During assembly, three side plates 101 and one top plate 102 are inserted into the mounting grooves 304 on the sides of the four support beams 301 respectively to form a rectangular cable laying frame. The splicing columns 202 on the side of the frame 201 are inserted into the splicing grooves 302 on the side of the support beam 301 and the support beam 301 is fixed, thereby fixing the adjacent support beams 301, realizing the assembly of the cable tray and maintaining an appropriate length.

[0024] The splicing column 202 has a second mounting hole 213 on its side. A return spring 205 is fixedly connected to the bottom of the second mounting hole 213, and a fixing pin 203 is fixedly connected to the top of the return spring 205. A fixing hole 303 is provided on the side of the splicing groove 302 corresponding to the position of the fixing pin 203. When the splicing column 202 is inserted into the splicing groove 302, the return spring 205 pushes the fixing pin 203 into the fixing hole 303, thereby fixing the splicing column 202 inside the fixing hole 303.

[0025] The fixing pin 203 has a bevel 209 on its side and the splicing post 202 has a rounded corner 208 on its side, which facilitates the insertion of the splicing post 202 into the fixing hole 303. When the splicing post 202 is inserted into the fixing hole 303, the bevel 209 contacts the side of the fixing hole 303, thereby pushing the fixing pin 203 into the second mounting hole 213.

[0026] The bottom end of the second mounting hole 213 is provided with a first mounting hole 212. An electromagnet 204 is fixedly connected to the side of the first mounting hole 212. A connecting rod 206 is fixedly connected to the bottom end of the fixing pin 203. An iron plate 207 is fixedly connected to the bottom end of the connecting rod 206. When the cable tray needs to be disassembled, the electromagnet 204 is energized to generate magnetic force, which in turn generates attraction force on the iron plate 207, causing the connecting rod 206 to drive the fixing pin 203 to move out of the fixing hole 303 and into the second mounting hole 213, so that the splicing column 202 can be moved out of the fixing hole 303.

[0027] Among them, the side of the frame 201 is fixedly connected to the fixing block 211, and the top of the fixing block 211 has a through hole, so that the bolt can pass through the through hole of the fixing block 211 to fix the cable tray to other objects.

[0028] The inner side wall of the frame 201 is provided with a placement groove 210. The bottom end of the placement groove 210 is movably connected to the bottom end of the side plate 101. The side plate 101 is provided with a slot 104. The length of the side plate 101 is greater than the length of the support beam 301. The slot 104 is located at the four corners of the side plate 101 and the slot 104 locks the side of the frame 201. When the splicing mechanism 2 fixes the support structure 3, the two ends of the side plate 101 and the top plate 102 are placed inside the placement groove 210, so that the joints of the protective plate mechanism 1 and the splicing mechanism 2 are staggered, reducing the entry of external debris into the cable tray.

[0029] The inner side wall of the support beam 301 is movably connected to the top plate 102. The side structure of the top plate 102 is the same as that of the side plate 101. The top of the top plate 102 is movably connected to the inspection door 103 through a hinge. The inspection door 103 facilitates the operator to inspect the internal cables of the assembled cable tray.

[0030] The working principle of this utility model is as follows: Based on usage requirements, select an appropriate number of protective plate mechanisms 1, splicing mechanisms 2, and support frames 3. During assembly, insert three side plates 101 and one top plate 102 into the mounting grooves 304 on the sides of the four support beams 301, forming a rectangular cable laying frame. The splicing columns 202 on the side of the frame 201 are inserted into the splicing grooves 302 on the side of the support beams 301. The inclined surface 209 contacts the side of the fixing hole 303, thereby pushing the fixing pin 203 into the second mounting hole 213. When the fixing pin 203 moves to the position of the fixing hole 303, it resets. Spring 205 pushes fixing pin 203 into fixing hole 303, thereby fixing splicing column 202 inside fixing hole 303, fixing adjacent support beam 301, assembling cable tray and maintaining appropriate length; during use, operators can inspect the internal cables of the assembled cable tray through inspection door 103. When the cable tray needs to be disassembled, electromagnet 204 is energized to generate magnetic force, thereby generating attraction force on iron plate 207, causing connecting rod 206 to drive fixing pin 203 out of fixing hole 303 and into second mounting hole 213, facilitating splicing column 202 to be moved out of fixing hole 303.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
