[0001] The present invention relates to the technical field of cable bridges, and in particular to a plug-in cable bridge and a use method thereof. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supports and installation accessories. The cable trays in buildings can be erected independently or attached to various buildings and pipe gallery brackets. They should have the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance. All parts of the cable trays installed in the open air outside the building must be galvanized.

At the same time, different types of cables are not effectively separated during the wiring process, but a mixed wiring method is adopted, which greatly increases the risk of leakage. Once leakage occurs, it will not only directly cause equipment damage, but also cause fire and other problems. In addition, mixed wiring also makes the subsequent maintenance and troubleshooting work extremely complicated, wasting manpower and increasing maintenance costs. Summary of the invention

[0011] As a preferred solution of a plug-in cable tray described in the present invention, the movable structure includes movable cavities symmetrically opened on the inner wall of the tray body, the inner cavities of two groups of the movable cavities are fixedly installed with guide rods, and the outer surfaces of the guide rods are slidably connected with T-shaped blocks, the opposite surfaces of the two groups of T-shaped blocks are fixedly connected to the two sides of the tray body, the outer surface of the guide rod is sleeved with a telescopic spring, and the two ends of the telescopic spring are respectively fixedly connected to the bottom end of the T-shaped block and the bottom end of the inner cavity of the movable cavity.

[0012] As a preferred solution of the plug-in cable tray described in the present invention, the placement groove includes a first storage groove a, a second storage groove b and a third storage groove c, which are separated by multiple groups of partition plates.

[0013] As a preferred solution of the plug-in cable tray described in the present invention, a through slot is opened in the middle of the bottom end of the placement rack, the through slot is communicated with the installation cavity, and the through slot is slidably connected to the movable plate.

[0017] As a preferred solution of the plug-in cable tray described in the present invention, when the two groups of guide plates are gradually rotated by 30° and 60°, the cables guided by the guide plates enter the second receiving groove b and the third receiving groove c respectively.

[0018] The present invention additionally provides a method for using a plug-in cable tray, which is applicable to the above-mentioned cable tray and specifically comprises the following steps:

[0019] S1: First, assemble multiple groups of bridge bodies through a plug-in structure, and pass the cables through the assembled bridge bodies;

[0020] S2: After laying, put the cable down, and the cable enters the transit cavity through the entrance groove opened by the placement rack. In the process of the cable falling, it first contacts the side wall of the shunt block, and it rotates clockwise as the cable is further pressed down, thereby expanding the space between the tail end of the shunt block and the inner wall of the regional transit cavity, ensuring that the cable slides smoothly into the placement groove. After the shunt block rotates a certain angle, it will fit with the inner wall of the entrance groove, and the shunt block is limited. When the second cable needs to be laid, the whole process will be repeated again, but this time the cable will fall into another placement groove. Through such repeated operations, not only can the cable position be centrally managed, which is convenient for subsequent cable bundling, but also the purpose of cable classification and wiring can be achieved;

[0021] S3: The cables that fall into the placement slot will first enter the first storage slot a. As the number of cables in the first storage slot a increases, the weight of the placement rack increases, and the placement rack moves downward through the moving structure. During the movement of the placement rack, the movable plate contacts the bottom end of the inner cavity of the bridge frame body and continuously moves upward, squeezing the connecting plates on both sides to rotate. The rotation process of the two sets of connecting plates will squeeze the guide plate to rotate. In this process, the newly fallen cables will slide along the surface of the guide plate and eventually be guided into different partitions of the placement slot space. As the angle of rotation of the guide plate changes, the cables can enter the second storage slot b and the third storage slot c respectively to further classify and route the cables.

[0022] Beneficial effects of the present invention:

[0023] 1. After the cable is passed through the entrance slot, it slides into the transfer cavity. The shunt block rotates clockwise as the cable is pressed down to widen the tail end space and ensure that the cable slides smoothly into the placement slot. At the same time, the shunt block rotates a certain angle and fits with the inner wall of the entrance slot. The limit shunt block rotates to guide the next cable to another slot. Repeat this process to achieve orderly classification and centralized management of cables, facilitate subsequent bundling and wiring, and improve work efficiency and neatness.

[0024] 2. As the number of cables in the first storage slot increases, the weight of the rack increases, and the movable structure moves downward to move the movable plate upward, squeezing the two sets of connecting plates to rotate, thereby driving the two sets of guide plates to turn. Subsequent cables slide along the guide plates and enter the second and third storage slots according to the rotation angle of the guide plates, thereby achieving fine classification of cables, simplifying maintenance, and saving labor costs.

[0041] Example 1

[0042] Reference Figure 1-Figure 10 , which is an embodiment of the present invention, provides a plug-in cable tray, including a main unit 100, a limiting unit 200 and a classification unit 300.

[0043] The main unit 100 includes a bridge frame body 101 and a cover plate 103 matched with the bridge frame body 101. The top of the bridge frame body 101 is symmetrically provided with a slide groove 102, and the slide groove 102 and the cover plate 103 are slidably connected. Both sides of the bridge frame body 101 are provided with a plurality of heat dissipation holes 104. The outer wall of the bridge frame body 101 is provided with a plug-in structure. First, multiple groups of bridge frame bodies 101 are assembled through the plug-in structure, and the cables are passed through the assembled bridge frame body 101.

[0044] The limiting unit 200 includes a placement rack 201 installed in the inner cavity of the bridge frame body 101, the top of the placement rack 201 is provided with an entrance groove 202, a transfer cavity 203 is provided on one side of the placement rack 201, and the transfer cavity 203 and the entrance groove 202 are communicated, a column 206 is provided at the bottom end of the transfer cavity 203, and the column 206 is fixedly connected to the placement rack 201, one side of the placement rack 201 is symmetrically provided with placement grooves 205, and two groups of placement grooves 205 are located on both sides of the column 206, and the two groups of placement grooves 205 are communicated with the transfer cavity 203, a mounting seat 207 is fixedly installed on the top of the column 206, one side of the mounting seat 207 is rotatably connected with a diverter block 204, and the top of the side wall of the diverter block 204 contacts the entrance groove 202, after the cable is put down, the cable passes The entrance slot 202 opened by the placement rack 201 enters the transfer chamber 203. During the falling process of the cable, it first contacts the side wall of the diverter block 204. As the cable is further pressed down, it rotates clockwise, thereby expanding the space between the tail end of the diverter block 204 and the inner wall of the regional transfer chamber 203, ensuring that the cable slides smoothly into the placement slot 205. After the diverter block 204 rotates a certain angle, it will fit with the inner wall of the entrance slot 202 to limit the diverter block 204. When the second cable needs to be laid, the whole process will be repeated again, but this time the cable will fall into another placement slot 205. Through such repeated operations, not only the cable position can be centrally managed, which is convenient for subsequent cable bundling, but also the purpose of cable classification and wiring can be achieved, solving the problem of scattered cables and difficult bundling.

[0045] The classification unit 300 includes an installation cavity 304 opened at the lower end of the column 206, the inner cavity of the installation cavity 304 is movably connected to a movable plate 303, the inner cavity of the movable plate 303 is fixedly installed with a rotating rod 306, and is located at the top of the movable plate 303, the two ends of the rotating rod 306 are rotatably connected to connecting plates 305, and two groups of connecting plates 305 are respectively located on both sides of the movable plate 303, movable grooves 307 are symmetrically opened on both sides of the column 206, and the inner cavities of the two groups of movable grooves 307 are rotatably connected to guide plates 301, two groups of partition plates 302 are installed at the top of the inner cavities of the two groups of placement grooves 205, and the inner cavity of the bridge frame body 101 is provided with a moving structure, and the cables dropped into the placement grooves 205 will first enter the first storage grooves 20 In 5a, as the number of cables in the first storage slot 205a increases, the weight of the placement rack 201 increases, and the placement rack 201 moves downward through the moving structure. During the movement of the placement rack 201, the movable plate 303 contacts the bottom end of the inner cavity of the bridge frame body 101 and continuously moves upward, squeezing the connecting plates 305 on both sides to rotate. The rotation process of the two sets of connecting plates 305 will squeeze the guide plate 301 to rotate. In this process, the newly fallen cables will slide along the surface of the guide plate 301. As the rotation angle of the guide plate 301 changes, they will eventually be guided into different partitions of the placement slot 205 space, further classifying and wiring the cables, reducing the difficulty of cable maintenance, and reducing manpower investment and costs.

[0046] The movable structure includes movable cavities 311 symmetrically opened on the inner wall of the bridge frame body 101, the inner cavities of the two groups of movable cavities 311 are fixedly installed with guide rods 314, and the outer surfaces of the guide rods 314 are slidably connected with T-shaped blocks 312, the opposite surfaces of the two groups of T-shaped blocks 312 are fixedly connected to the two sides of the bridge frame body 101, the outer surface of the guide rods 314 is sleeved with telescopic springs 313, and the two ends of the telescopic springs 313 are respectively fixedly connected to the bottom ends of the T-shaped blocks 312 and the bottom ends of the inner cavities of the movable cavities 311. As the weight of the bridge frame body 101 gradually increases, it will directly apply pressure to the T-shaped blocks 312. The T-shaped blocks 312 were originally maintained at the top position by the telescopic springs 313 in the extended state. After being compressed, the telescopic springs 313 began to be compressed. This compression process prompts the T-shaped blocks 312 to move downward along the surface of the guide rods 314. As the T-shaped blocks 312 descend, they correspondingly drive the bridge frame body 101 to move downward together.

[0047] The placement slot 205 includes a first receiving slot 205a, a second receiving slot 205b and a third receiving slot 205c, which are divided by a plurality of partition plates 302 and are used for separating and routing cables.

[0048] A through slot 308 is provided in the middle of the bottom of the placement rack 201 . The through slot 308 is communicated with the installation cavity 304 , and the through slot 308 is slidably connected with the movable plate 303 . The movable plate 303 moves up and down in the inner cavities of the installation cavity 304 and the through slot 308 .

[0049] The inner wall of the through groove 308 is symmetrically provided with moving grooves 309 , and the inner cavities of the two groups of moving grooves 309 are slidably connected with moving blocks 310 , and the opposite surfaces of the two groups of moving blocks 310 are slidably connected to the two sides of the movable plate 303 to ensure the stability of the movable plate 303 during movement.

[0050] The plug-in structure also includes an insert block 105 symmetrically installed on one side of the bridge frame body 101, and a threaded groove is provided on one side of the insert block 105. A slot 107 is symmetrically provided on the side of the bridge frame body 101 away from the insert block 105, and the slot 107 and the insert block 105 are snap-connected. Two groups of slots 107 are provided with threaded holes 106 on the side away from the placement frame 201, and the threaded holes 106 and the threaded grooves are matched. One group of bridge frame bodies 101 is inserted into another group of slots 107 through the insert block 105 to complete the initial fixation, and then connected to the threaded groove box and threaded hole 106 through bolts to complete the final assembly.

[0051] The outer surfaces of the two groups of guide plates 301 are provided with a plurality of groups of rollers 315 to reduce the friction between the cables and the guide plates 301 , so that the cables can slide down the guide plates 301 faster and more smoothly.

[0052] When the two sets of guide plates 301 are gradually rotated by 30° and 60°, the cables guided by the guide plates 301 enter the second receiving groove 205b and the third receiving groove 205c respectively.

[0053] Example 2

[0054] A method for using a plug-in cable tray, using a plug-in cable tray in Example 1, specifically comprising the following steps:

[0055] S1: First, assemble multiple groups of bridge bodies 101 through a plug-in structure, and pass the cables through the assembled bridge bodies 101;

[0056] S2: After laying, put down the cable, and the cable enters the transfer chamber 203 through the entrance groove 202 opened by the placement rack 201. In the process of the cable falling, it first contacts the side wall of the shunt block 204, and it rotates clockwise as the cable is further pressed down, thereby expanding the space between the tail end of the shunt block 204 and the inner wall of the regional transfer chamber 203, ensuring that the cable slides smoothly into the placement groove 205. After the shunt block 204 rotates a certain angle, it will fit with the inner wall of the entrance groove 202, and the shunt block 204 is limited. When it is necessary to lay the second cable, the whole process will be repeated again, but this time the cable will fall into another placement groove 205. Through such repeated operations, not only can the cable position be centrally managed, but also the subsequent cable bundling can be convenient, and the purpose of cable classification and wiring can be achieved at the same time;

[0057] S3: The cables that fall into the placement groove 205 will first enter the first storage groove 205a. As the number of cables in the first storage groove 205a increases, the weight of the placement rack 201 increases, and the placement rack 201 moves downward through the moving structure. During the movement of the placement rack 201, the movable plate 303 contacts the bottom end of the inner cavity of the bridge frame body 101 and continuously moves upward, squeezing the connecting plates 305 on both sides to rotate. The rotation process of the two sets of connecting plates 305 will squeeze the guide plate 301 to rotate. In this process, the newly fallen cables will slide along the surface of the guide plate 301 and are finally guided into different partitions of the placement groove 205 space. As the rotation angle of the guide plate 301 changes, the cables can enter the second storage groove 205b and the third storage groove 205c respectively to further classify and route the cables.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.

A method for using a plug-in cable tray, using the hoisting structure of claim 7, specifically comprising the following steps: S1: firstly assembling a plurality of bridge bodies (101) through a plug-in structure, and threading cables inside the assembled bridge bodies (101); S2: After laying, the cable is lowered, and the cable enters the transfer chamber (203) through the entrance groove (202) opened by the placement rack (201). In the process of the cable falling, it first contacts the side wall of the shunt block (204), and it rotates clockwise as the cable is further pressed down, thereby expanding the space between the tail end of the shunt block (204) and the inner wall of the regional transfer chamber (203), ensuring that the cable slides smoothly into the placement groove (205). After the shunt block (204) rotates a certain angle, it will fit with the inner wall of the entrance groove (202), and the shunt block (204) is limited. When it is necessary to lay the second cable, the whole process will be repeated again, but this time the cable will fall into another placement groove (205). Through such repeated operations, not only can the cable position be centrally managed, but also the subsequent bundling of the cables is convenient, and the purpose of cable classification and wiring can be achieved at the same time; S3: The cables that fall into the placement groove (205) will first enter the first receiving groove (205a). As the number of cables in the first receiving groove (205a) increases, the weight of the placement rack (201) increases, and the placement rack (201) moves downward through the moving structure. During the movement of the placement rack (201), the movable plate (303) contacts the bottom end of the inner cavity of the bridge frame body (101) and continuously moves upward, squeezing the connecting plates (305) on both sides to rotate. The rotation process of the two groups of connecting plates (305) will squeeze the guide plate (301) to rotate. In this process, the newly dropped cables will slide along the surface of the guide plate (301) and will eventually be guided into different partitions of the placement groove (205). As the angle of rotation of the guide plate (301) changes, the cables can enter the second receiving groove (205b) and the third receiving groove (205c) respectively, so as to further classify and route the cables.
