Description

Technical Field

[0001] This utility model belongs to the field of power distribution box installation technology, and more specifically, it relates to a wall-mounted DC power distribution box. Background Technology

[0002] DC power distribution boxes are key equipment in power systems used to distribute DC power, and are widely used in scenarios with high requirements for power supply stability, such as communication base stations and new energy power plants.

[0003] Currently, existing DC power distribution boxes need to be fixed to the wall with bolts without pre-positioning. The lack of an effective pre-positioning structure before installation makes the distribution box prone to displacement or shaking during the initial fixing stage, which greatly reduces installation efficiency. The distribution box is often disassembled and reassembled due to equipment maintenance, function upgrades, or fault replacement. Each disassembly and reassembly requires tightening the bolts one by one, which is a cumbersome and lengthy process. This not only increases time costs, but repeated disassembly and reassembly can also cause cumulative damage to the connection structure between the bolts and the wall, reducing the reliability and stability of subsequent installations.

[0004] To address the aforementioned issues, this application proposes a wall-mounted DC power distribution box. Utility Model Content

[0005] The purpose of this utility model is to provide a wall-mounted DC power distribution box that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a wall-mounted DC power distribution box, including the distribution box and further comprising:

[0008] Two L-shaped fixing brackets are respectively fixed to the upper and lower ends of the fixing back plate fixed on the back of the distribution box, and the L-shaped fixing brackets are provided with slots;

[0009] Two L-shaped support frames are fixedly connected to the upper and lower ends of the vertical plate, respectively. A fixed seat is fixedly provided on the top surface of the L-shaped support frame, and the fixed seat and the L-shaped support frame form a groove that cooperates with the side wall of the L-shaped fixed frame.

[0010] The insert is set in a fixed base, and the fixed base is also provided with a lifting plate that is linked to the insert. The lifting plate is used to drive the insert to be inserted into or separated from the slot.

[0011] Furthermore, the side wall of the fixed base is provided with a receiving groove for accommodating the insert, and the end of the insert is fixed with a slide rod that is slidably connected to the fixed base.

[0012] Furthermore, the lifting plate is disposed in the cavity opened in the fixed seat, and the side wall of the lifting plate is fixedly provided with a fixed shaft that is rotatably connected to one end of the connecting rod, and the slide rod is fixedly provided with a hinge seat that is hinged to the other end of the connecting rod.

[0013] Furthermore, the side wall of the fixed base is provided with a receiving groove for accommodating the insert, and the end of the insert is fixed with a slide rod that is slidably connected to the fixed base.

[0014] Furthermore, a lifting plate is provided in the cavity of the fixed seat, and a fixed shaft is fixedly provided on the side wall of the lifting plate and rotatably connected to one end of the connecting rod. The slide rod is fixedly provided with a hinge seat that is hinged to the other end of the connecting rod.

[0015] Furthermore, a screw rod that is threadedly connected to the lifting plate is rotatably installed inside the cavity, and the two screw rods are fixedly connected by a connecting shaft.

[0020] This utility model has the following beneficial effects:

[0021] This utility model first installs the vertical plate to the wall, and then uses the groove formed by the L-shaped fixing frame, L-shaped support frame and fixing seat to realize the pre-installation of the distribution box and the vertical plate in a hanging form. When fixing the distribution box, there is no need to apply support force to it, which simplifies the installation process. In addition, the distribution box is not directly connected to the wall, and the disassembly and assembly of the distribution box will not affect the connection structure between the wall and the vertical plate.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Please see Figure 1 - Figure 5 As shown, this utility model is a wall-mounted DC power distribution box, including a distribution box 1. It is characterized by further comprising: two L-shaped fixing frames 3, respectively fixed to the upper and lower ends of a fixing back plate 2 fixed to the back of the distribution box 1; the L-shaped fixing frames 3 having slots 301; two L-shaped support frames 4, respectively fixed to the upper and lower ends of a vertical plate 5; a fixing seat 14 fixed to the top surface of the L-shaped support frame 4, and the fixing seat 14 and the L-shaped support frame 4 forming a groove that engages with the side wall of the L-shaped fixing frame 3; and a plug 6 disposed within the fixing seat 14, the fixing seat 14 also having a lifting plate 9 linked to the plug 6, the lifting plate 9 being used to drive the plug 6 to engage or disengage from the slots 301.

[0035] The vertical plate 5 has mounting holes for connection to the wall. The fixed back plate 2 is fixed to the distribution box 1 by welding or bolts. The horizontal side wall of the L-shaped fixing frame 3 is fixed to the fixed back plate 2. The horizontal side wall of the L-shaped support frame 4 is fixed to the vertical plate 5. The vertical side wall of the L-shaped support frame 4 and the fixing seat 14 form a groove that is inserted into the vertical side wall of the L-shaped fixing frame 3. The plug 6 can move horizontally and be inserted into the slot 301 to fix the L-shaped fixing frame 3, thus realizing the mounting of the distribution box 1.

[0036] The fixed base 14 has a receiving groove 1402 on its side wall for accommodating the insert 6. The end of the insert 6 is fixed with a slide rod 7 that is slidably connected to the fixed base 14. The lifting plate 9 is set in the cavity 1401 opened in the fixed base 14. The side wall of the lifting plate 9 is fixed with a fixed shaft 901 that is rotatably connected to one end of the connecting rod 8. The slide rod 7 is fixed with a hinge seat 701 that is hinged to the other end of the connecting rod 8. When the lifting plate 9 moves vertically, it can drive the connecting rod 8 to move, thereby driving the insert 6 to move laterally through the slide rod 7, so as to realize the insertion or separation of the insert 6 from the slot 301.

[0037] The cavity 1401 contains a screw 10 that is threadedly connected to the lifting plate 9. The two screws 10 are fixedly connected by a connecting shaft 13. Both fixed seats 14 contain screws 10. The screws 10 are set perpendicular to the horizontal plane. The connecting shaft 13 is used to link the two screws 10 together, ensuring that the two screws 10 rotate synchronously, so that the inserts 6 at different horizontal heights move synchronously, and lock and unlock the L-shaped fixing frame 3 synchronously.

[0038] The cavity 1401 is fixed with a guide rod 11 that is slidably connected to the lifting plate 9. The guide rod 11 is parallel to the screw 10 and passes through the lifting plate 9. The guide rod 11 restricts the rotational freedom of the lifting plate 9 so that it can only move along the axial direction of the screw 10.

[0039] One end of a screw 10 away from the connecting shaft 13 is fixed to a handwheel 12 via a rotating shaft. The handwheel 12 drives the screw 10 to rotate, thereby controlling the lifting plate 9 to rise and fall.

[0040] The L-shaped fixing frame 3 is fixedly connected to multiple reinforcing plates 302. The L-shaped support frame 4 and the positioning groove 401 of the reinforcing plate 302 are used to strengthen the connection between the horizontal and vertical side walls of the L-shaped fixing frame 3. The reinforcing plates 302 are evenly distributed along the length of the L-shaped fixing frame 3. When the L-shaped fixing frame 3 is inserted into the groove formed by the L-shaped support frame 4 and the fixing seat 14, the reinforcing plate 302 is embedded in the positioning groove 401, which plays a positioning role for the L-shaped fixing frame 3. The auxiliary slot 301 is aligned with the insert block 6, which can also prevent the L-shaped fixing frame 3 from sliding in the horizontal direction.

[0041] The slide rod 7 has a limiting ring 702 fixed on its outer wall and is located in the cavity 1401. The limiting ring 702 is used to limit the movement of the slide rod 7 and prevent the slide rod 7 from moving outward too much and separating from the fixed seat 14.

[0042] It is understandable that after the vertical plate 5 is fixed to the wall, the present invention uses an L-shaped fixing bracket 3 and an L-shaped support bracket to hang the distribution box 1 quickly. The distribution box 1 is not directly connected to the wall, and disassembly and assembly do not affect the connection between the wall and the vertical plate 5. The plug 6 slot 301 locks the L-shaped fixing bracket 3 to prevent it from falling off, while improving the fixing efficiency and shortening the hanging time.

[0043] A specific application of the operation process of this embodiment is as follows: During installation, the vertical section of the L-shaped fixing frame 3 is inserted into the groove formed by the vertical section of the L-shaped support frame 4 and the fixing seat 14. At this time, the slot 301 is embedded in the positioning slot 401, and the slot 301 is aligned with the plug 6. The handwheel 12 is rotated to drive the two screws 10 to rotate, which further drives the lifting plate 9 to descend along the guide rod 11. The lifting plate 9 drives the slide rod 7 and the plug 6 to move towards the distribution box 1 through the connecting rod 8. The plug 6 is inserted into the slot 301, and the installation of the distribution box 1 is completed.

[0044] During disassembly, rotate the handwheel 12 in the opposite direction to drive the screw 10 to rotate, causing the lifting plate 9 to rise. The lifting plate 9, through the connecting rod 8, drives the sliding rod 7 and the plug 6 away from the distribution box 1. The plug 6 is fully retracted into the receiving groove 1402, releasing the fixation of the L-shaped fixing bracket 3, and the distribution box 1 can be lowered.
