Description

Technical Field

[0001] This utility model relates to the field of cable branch box technology, and in particular to an assembled cable branch box. Background Technology

[0002] With the development of cable distribution networks, when small-capacity independent loads are concentrated, cable branch boxes can be used to connect multiple cable branches. Because branch boxes cannot be directly operated on each line, they are only used as cable branches. The main function of cable branch boxes is to split and transfer cables. They are widely used outdoors. Existing cable branch boxes are mainly designed in a rectangular shape. During the manufacturing process, cable branch boxes are generally fixed by welding or bolts, which makes the assembly process of cable branch boxes cumbersome and inconvenient to use. In addition, cable branch boxes generate heat during use, which can damage internal components. Current heat dissipation methods are mostly through openings, which are ineffective.

[0003] Publication number CN219477581U discloses an assembled cable branch box, including a lower housing, an upper housing on the upper surface of the lower housing, connecting grooves at the four corners of the upper surface of the lower housing, and slots on one side of the inner wall of each connecting groove. Connecting blocks are fixedly connected to the four corners of the lower surface of the upper housing, and receiving grooves are provided on the lower part of the outer surface of each connecting block. Spring plates are fixedly connected inside each receiving groove, and locking blocks are fixedly connected to the other side of each spring plate. Installation sleeves are fixedly connected to the upper part of the outer surfaces on both sides of the upper housing. In this invention, by inserting the connecting blocks into the connecting grooves, the spring plates push the locking blocks into the grooves when they slide to the opening, thus fixing the upper and lower housings together. This facilitates the assembly and disassembly of the cable branch box and improves its usability.

[0004] While the above solution facilitates the assembly and disassembly of the cable branch box, the assembly and disassembly of the cable branch box requires multiple simultaneous operations, which is quite troublesome. Furthermore, the mutual limiting effect of the various parts of the cable branch box is generally not good. Therefore, we propose an assembled cable branch box. Utility Model Content

[0005] The main purpose of this utility model is to provide an assembled cable branch box. By setting a limiting unit and an assembly unit, it solves the problems that the disassembly and assembly of the cable branch box requires multiple synchronous operations, which is cumbersome, and the mutual limiting effect of the various parts of the cable branch box is generally not good.

[0006] To solve the above technical problems, this utility model is achieved through the following technical solution: an assembled cable branch box, including an "L"-shaped back plate, a placement groove is provided at the center of the concave surface at the bottom of the back plate, three assembly shells are stacked in the placement groove, and further includes: a limiting unit and an assembly unit disposed between the back plate and the assembly shells;

[0007] The limiting unit includes a lead screw, a support block, an extension frame, a limiting cover plate, and a limiting bolt. A receiving groove is provided on the concave surface of the side of the back plate. A strip-shaped mounting groove is provided on each of the two opposite sides of the receiving groove. The lead screw is movably mounted on one of the strip-shaped mounting grooves. There are two support blocks, which are located on the two strip-shaped mounting grooves respectively. One of the support blocks is threadedly connected to the lead screw. The extension frame is in the shape of an inverted "U" and is fixedly mounted between the two support blocks. A threaded hole is provided at the center of the top surface of the extension frame. The limiting cover plate is placed on the top surface of the extension frame and is located directly above the three assembled housings. A positioning through hole is provided on the top surface of the limiting cover plate. The limiting bolt movably passes through the positioning through hole and is assembled on the threaded hole.

[0008] The assembly unit includes frame-shaped connecting strips, frame-shaped blocks, and plug-in strips. The top surfaces of the two lower assembly housings are provided with frame-shaped grooves, and the bottom surfaces of the two upper assembly housings are fixedly provided with frame-shaped connecting strips. The three assembly housings are assembled together through the frame-shaped grooves and frame-shaped connecting strips. There are a total of six frame-shaped blocks, which are divided into three groups. The three groups of frame-shaped blocks are fixedly provided on opposite sides of the three assembly housings. Two plug-in strips are symmetrically fixedly provided on the bottom surface of the limiting cover plate, and each plug-in strip corresponds to and moves through the three frame-shaped blocks located on the same side of the three assembly housings.

[0009] Preferably, the limiting unit further includes a guide rod, which is fixedly mounted on another strip-shaped mounting groove and movably passes through another support block.

[0010] Preferably, a turntable is fixedly installed on the end face of the lead screw located outside the back plate.

[0011] Preferably, the insertion strip and the lead screw are arranged parallel to each other.

[0012] Preferably, each of the three assembled housings has a door installed on one side surface.

[0013] Preferably, a support leg is fixedly provided at the corner of the bottom surface of the backing plate.

[0014] Compared with the prior art, the assembled cable branch box of this utility model has the following advantages:

[0015] 1. In this utility model, by setting a limiting unit, after the three assembled shells are stacked in the center of the concave surface at the bottom of the back plate through the placement groove, the limiting cover plate can be placed on the top surface of the extension frame which is shaped like an inverted "U". The positioning through hole and the threaded hole are aligned. The limiting bolt is installed on the threaded hole to clamp and fix the limiting cover plate to the extension frame. By rotating the screw in both directions outside the back plate, one of the support blocks connected to the screw threadedly can be driven to move the extension frame up and down on the storage groove under the force. The other support block can slide up and down on the guide rod to cooperate with the adjustment of the extension frame and provide auxiliary support. The limiting cover plate can move down to press against the top of the three assembled shells to complete the positioning. After the limiting cover plate moves up, the three assembled shells can be removed in sequence. The equipment is simple and flexible in disassembling and assembling the assembled shells.

[0016] 2. In this utility model, by setting an assembly unit, three assembly shells can be connected to each other through frame-shaped grooves and frame-shaped connecting strips. When the limiting cover plate moves down, it can press against the top of the three assembly shells. At the same time, the two plug-in strips symmetrically fixed on the bottom surface of the limiting cover plate can move through the three sets of frame-shaped blocks on opposite sides of the three assembly shells in sequence. The three assembly shells can be synchronously positioned on the two plug-in strips through the three sets of frame blocks to further connect and maintain their position. Moreover, the plug-in strips can be synchronously adjusted with the limiting cover plate. The equipment has a tight and stable assembly and positioning of the three assembly shells.
