Description

Technical Field

[0001] The present application relates to the technical field of distribution boxes, and in particular to a distribution box for automatically powering off a new energy charging pile. Background Art

[0002] A charging pile is a device that provides power replenishment for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on the wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots. It can charge various types of electric vehicles according to the adjusted voltage and current.

[0003] The charging pile controls the circuit through the distribution box. There are many electrical components inside the distribution box. After long-term use, some components may be damaged or short-circuited. When inspecting and replacing components, because the distribution box is fixed on the wall, the staff can only operate at the door of the distribution box. However, since there are many internal lines in the distribution box and the internal operating space is limited, it is inconvenient for the staff to put their hands into the distribution box to operate, which affects the inspection efficiency and is inconvenient.

A pair of box doors 2 are hinged on one side of the distribution box shell 1. Both box doors 2 are provided with observation windows 3. The side opposite to the box door 2 on the distribution box shell 1 is open, and the open side is in contact with the mounting plate 4; a pair of connecting pieces 19 are fixed at the top of the distribution box shell 1, and positioning holes 20 are opened on both connecting pieces 19; a limiting mechanism is also included, which is installed on the mounting plate 4 through the fixing plate 6 in the limiting mechanism, so as to limit and fix the distribution box shell 1 on the mounting plate 4.

[0021] A pair of fixing plates 15 are fixed to the upper end of the mounting plate 4, and a positioning column 16 is fixed to the top surface of the fixing plate 15. The positioning columns 16 are respectively adapted to the positioning holes 20. A pair of fixing angle plates 5 are fixed to the lower end of the mounting plate 4. The two fixing angle plates 5 are symmetrically arranged, and the spacing between the two fixing angle plates 5 is the same as the width of the distribution box housing 1. The distribution box housing 1 is clamped between the two fixing angle plates 5. The limiting mechanism also includes a limiting rod 7 that is slidably sleeved on the fixing plate 6. The first end surface of the limiting rod 7 is provided with a chamfer. Part 14, the limiting rod 7 passes through the fixed angle plate 5 and is slidably connected to the fixed angle plate 5. A pull ring 10 is fixed at the tail end of the limiting rod 7. On the limiting rod 7, a force plate 701 is fixed near the head end, and a thrust spring 9 is sleeved on the outer ring of the limiting rod 7. The thrust spring 9 is respectively connected to the fixed plate 6 and the force plate 701. The limiting rod 7 can be moved by the tension of the thrust spring 9. Fixing holes 17 are provided on both sides of the bottom end of the distribution box shell 1, and the fixing holes 17 are respectively adapted to the limiting rod 7.

[0022] When in use, the mounting plate 4 is provided with a plurality of waist-shaped holes for fixing it to the wall by bolts. After fixing the mounting plate 4, the limiting rods 7 are pulled outwards to keep them away from the fixed angle plate 5. Then, the two connecting pieces 19 at the top of the distribution box housing 1 are respectively sleeved on the positioning columns 16 to achieve initial stability. At this time, the lower end of the distribution box housing 1 is clamped between the two fixed angle plates 5. The limiting rods 7 are respectively passed through the fixed angle plates 5 and inserted into the fixing holes 17 to complete the installation and fixation. The electrical components are installed on the mounting bracket on the distribution box housing 1.

[0023] In this embodiment, if Figure 3As shown, a plurality of wire openings 18 are provided at the bottom of the distribution box housing 1, and the wire openings 18 extend to the bottom edge of the distribution box housing 1, which facilitates the disassembly of the distribution box housing 1 during maintenance and avoids obstruction or entanglement of the wires.

[0024] In this embodiment, if Figure 2 As shown, an extension portion 13 is fixed on the limit rod 7, and a support plate 8 is fixed on the side of the fixing plate 6 away from the fixed angle plate 5. The support plate 8 is provided with a first cutout 11 and a second cutout 12. When the limit rod 7 is inserted into the fixing hole 17, the limit rod 7 is rotated so that the extension portion 13 is in the second cutout 12. At this time, the movement of the limit rod 7 can be restricted, and the installation stability can be improved. When disassembling, after the limit rod 7 is away from the fixing hole 17, the limit rod 7 is rotated so that the extension portion 13 is in the first cutout 11. At this time, the limit rod 7 can be resisted to prevent it from resetting, thereby facilitating the operation of the other limit rod 7 and improving practicality.
