[0002] An electrical control cabinet is a centralized control device used to control and manage motors, production lines, factory equipment, or other electrical equipment. It is a core component of electrical automation systems and is crucial for ensuring the efficient and safe operation of industrial processes. The electrical control cabinet contains a variety of electrical components and control switches, which are configured according to specific logic and programs to achieve precise control of connected mechanical or electrical systems.

[0003] Because electrical control cabinets contain numerous electrical components and control switches, they have a large amount of internal wiring. To prevent the wiring from becoming tangled and affecting subsequent maintenance, U-shaped cable trays are typically used to organize and store the wires. Additionally, to restrain and protect the wires stored within the cable trays, tray covers are installed at the openings. Currently, the installation of cable trays and covers generally involves a locking mechanism on the outside of the cable tray and a recess on the inside of the cover to achieve the connection. The disadvantage of this method is that disassembly is very inconvenient; excessive force often damages the locking mechanism, rendering the cover unusable and causing significant inconvenience for the maintenance of the electrical control cabinet. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a wire storage box for electrical control cabinets that is easy to repeatedly disassemble and reassemble, thus facilitating the maintenance of electrical control cabinets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable storage box for an electrical control cabinet includes a U-shaped cable trough whose bottom is fixedly connected to the inner wall of the electrical control cabinet, an inverted U-shaped cover that snaps onto the opening of the cable trough, and a connecting mechanism disposed on the cover. The connecting mechanism includes a connecting box, two locking rods, two mounting rods, and a locking rod drive assembly. The connecting box is fixed to the top of the cover. The lower ends of the two mounting rods are respectively connected to the top of the two side walls of the cable trough, and the upper ends pass through the vertical fixing holes in the two side walls of the cover and are provided with locking holes.

The outer ends of the two locking rods are respectively opposite to the locking holes at the upper ends of the two mounting rods, and the inner ends are connected to the locking rod drive assembly.

[0007] The aforementioned electrical control cabinet cable storage box includes a locking rod drive assembly comprising a lifting plate, two rotating arms, and a threaded rod disposed inside the connection box. One end of each of the two rotating arms is rotatably connected to the inner end of one of the two locking rods, and the other end is rotatably connected to both ends of the lifting plate. The threaded rod passes through the central hole of the lifting plate and is threadedly connected to the lifting plate. The lower end of the threaded rod is rotatably connected to the bottom plate of the connection box, and the upper end passes through the top plate of the connection box and is provided with a rotating handle.

[0008] The aforementioned electrical control cabinet cable storage box, the locking rod drive assembly further includes two guide rods, which are symmetrically arranged on both sides of the threaded rod and parallel to the threaded rod. The two guide rods slide through the guide holes on the lifting plate, and the two ends of each guide rod are fixedly connected to the inner wall of the connecting box.

[0009] The above-mentioned electrical control cabinet cable storage box has two side walls with slots at the lower ends that match the top of the two side walls of the U-shaped cable groove.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0020] Please see Figures 1-4 The electrical control cabinet 101 houses multiple electrical components 102 mounted on mounting brackets. The inner wall of the electrical control cabinet 101 is equipped with a wire storage box for organizing and storing the wires of each electrical component 102. This utility model includes a U-shaped wire trough 103 whose bottom is fixedly connected to the inner wall of the electrical control cabinet 101, an inverted U-shaped cover 104 that snaps onto the opening of the wire trough 103, and a connecting mechanism on the cover 104 for connecting to the wire trough 103. The lower ends of the two side walls of the inverted U-shaped cover 104 are provided with slots 204 that match the tops of the two side walls of the U-shaped wire trough 103. The width of the two slots 204 is slightly larger than the width of the side walls of the wire trough 103, thus facilitating insertion into the side walls of the wire trough 103.

[0021] The connecting mechanism includes a connecting box 201, two locking rods 203, two mounting rods 205, and a locking rod drive assembly. The connecting box 201 is fixedly connected to the top of the slot cover 104 (on the side away from the wire slot 103). The lower ends of the two mounting rods 205 are fixedly connected to the top of the two side walls of the wire slot 103, respectively, and the upper ends pass through the vertical fixing holes in the two side walls of the slot cover 104 and are provided with locking holes 206. Through holes 202 are provided on both side walls of the connecting box 201. The two locking rods 203... The two locking rods 203 are coaxial with each other and slide through the two through holes 202 respectively. The outer ends of the two locking rods 203 are opposite to the locking holes 206 at the upper ends of the two mounting rods 205 respectively, and the inner ends are connected to the locking rod drive assembly. When the two locking rods 203 are inserted into the locking holes 206 under the drive of the locking rod drive assembly, the slot cover 104 and the wire groove 103 can be fixedly connected together. When the two locking rods 203 are pulled out of the locking holes 206 under the drive of the locking rod drive assembly, the slot cover 104 and the wire groove 103 can be separated.

[0022] It should be noted that this utility model achieves the connection and separation between the slot cover 104 and the wire trough 103 through a connecting mechanism. Compared with the conventional snap-fit ​​connection method, this reduces the probability of damage to the slot cover 104 and facilitates the repeated installation and use of the slot cover 104 and the wire trough 103.

[0023] Please see Figure 4 The side wall of the locking rod 203 is provided with a sliding groove 301, and a sliding plate 302 is slidably connected in the sliding groove 301. One end of the sliding plate 302 is connected to the inner wall of the through hole 202. The sliding groove 301 and the sliding plate 302 play a guiding and limiting role for the movement of the locking rod 203.

[0024] Please see Figure 3 The locking rod drive assembly includes a lifting plate 501, two rotating arms 502, two guide rods 7, and a threaded rod 601 disposed inside the connecting box 201. One end of each of the two rotating arms 502 is rotatably connected to the inner end of each of the two locking rods 203, and the other end is rotatably connected to both ends of the lifting plate 501. The threaded rod 601 passes through the central hole of the lifting plate 501 and is threadedly connected to the lifting plate 501. The lower end of the threaded rod 601 is rotatably connected to the bottom plate of the connecting box 201, and the upper end passes through the top plate of the connecting box 201 and is provided with a rotating handle 602. The two guide rods 7 are symmetrically disposed on both sides of the threaded rod 601 and are parallel to the threaded rod 601. The two guide rods 7 slide through the guide holes on the lifting plate 501, and both ends of each guide rod 7 are fixedly connected to the inner wall of the connecting box 201.

[0025] Two guide rods 7 guide the lifting plate 501. Multiple connecting mechanisms are provided, and these mechanisms are arranged at equal intervals along the length of the groove cover 104.

[0026] Working principle: In use, excess or exposed wires in the electrical control cabinet 101 are placed in the wire trough 103. Then, the trough cover 104 is fastened onto the wire trough 103, and the side wall of the wire trough 103 is inserted into the slot 204. The upper end of the mounting rod 205 passes through the vertical fixing hole in the side wall of the trough cover 104. Then, by rotating the handle 602, the threaded rod 601 is rotated, which drives the lifting plate 501 to move downward. The lifting plate 501 pushes the two locking rods 203 to move to both sides through the two rotating arms 502. When the two locking rods 203 are inserted into the locking holes 206 on the mounting rod 205, the rotation of the handle 602 is stopped. At this time, the connection limit between the trough cover 104 and the wire trough 103 is realized by the limiting action of the two locking rods 203 and the mounting rod 205. When it is necessary to remove the slot cover 104, simply rotate the handle 602 in the opposite direction to move the lifting plate 501 upward, so that the two locking rods 203 can be pulled out from the locking holes 206 on the mounting rod 205, and the slot cover 104 can be removed.
