[0025] Furthermore, multiple sets of fastening screws 4 are provided, and the multiple sets of fastening screws 4 are evenly distributed at both sides of the bottom end of the protection frame 2 in a linear array manner. The bottom ends of the fastening screws 4 pass through the bottom end of the protection frame 2 and are threadedly connected to the base bin 1. Figure 1 and attached Figure 2 As shown, it is convenient to disassemble and install the base bin 1 and the protective frame 2.

[0026] Further, one side of the top of the closed door 5 is slidably connected to one side of the top of the protective frame 2, and the bottom end of the closed door 5 is slidably connected to the top of the base bin 1. Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the closed door 5 slides more smoothly.

[0027] Further, a positive plate 16 is fixed to one side of the interior of the square groove 9, a negative plate 17 is fixed to the other side of the interior of the square groove 9, a conductive spring 18 is fixed to one side of the positive plate 16 and the negative plate 17, a conductive plate 19 is fixed to one end of the conductive spring 18, and the conductive plate 19 slides inside the square groove 9, and two groups of conductive plates 19 are provided, and there is an obvious gap between the two groups of conductive plates 19, and the other side of the negative plate 17 is connected to the wire 20, and the wire 20 is located inside the base compartment 1, according to the attached Figure 4 As shown, the interruption and connection of the series circuit of the external device becomes controllable.

[0028] Furthermore, a fixed plate 8 is fixed to one end of the front side of the closed door 5, and a movable plate 11 is slidably inserted through one end of the closed door 5, and an electrified iron plate 12 is fixed to the bottom of one end of the movable plate 11, and the electrified iron plate 12 is slidably inserted in the middle of the two groups of conductive plates 19, and the width of the electrified iron plate 12 is greater than the gap distance between the two groups of conductive plates 19, and a movable rod 13 is slidably inserted through the other end of the movable plate 11, and a limiting nut 14 is slidably sleeved on the outer surface of the movable rod 13, and the limiting nut 14 is located in the middle of the fixed plate 8 and the other end of the movable plate 11, and the top end of the movable rod 13 is slidably inserted in the middle of the fixed plate 8, and a clamping column 15 is fixed to the bottom of the other end of the movable plate 11. Figure 1 , Attachment Figure 3 and attached Figure 4As shown, preparations are made for plugging and unplugging the energized iron plate 12 inside the two sets of conductive plates 19.

[0029] Furthermore, a slide groove is provided at one end of the closed door 5, and the middle of the movable plate 11 slides inside the slide groove. The outer surface of the movable plate 11 is wrapped with a rubber insulating sheet. Figure 1 and attached Figure 3 As shown, conditions are provided for the smooth up and down movement of the moving plate 11, while preventing leakage events from occurring.

[0030] Further, the top of the moving rod 13 is set as a thick cylinder, and the outer surface of the bottom end of the thick cylinder is provided with a threaded ring, the threaded ring is adapted to the limit nut 14, the limit nut 14 is threadedly sleeved on the outer surface of the bottom end of the thick cylinder, and the bottom end of the moving rod 13 is set as a thin cylinder. Figure 1 and attached Figure 3 As shown, it is convenient to limit the height position of the energized iron plate 12 when the energized iron plate 12 is inserted between the two sets of conductive plates 19, so as to prevent the energized iron plate 12 from being separated and causing circuit interruption.

[0031] Furthermore, the card column 15 is adapted to the card slot 10, and the bottom end of the card column 15 is slidably inserted into the inside of the card slot 10, and a ball is rolled on the bottom end of the card column 15. Figure 1 and attached Figure 3 As shown, the closed door 5 will not slide open easily due to external interference, ensuring the safety of the device. At the same time, the ball bearing can reduce the influence of excessive friction resistance of the base bin 1 on the clamping column 15 when the closed door 5 slides.

[0032] Working principle: When using, first place the base bin 1 in a suitable position. The base bin 1 is made of FRP reinforced plastic material, which has the advantages of high hardness, good corrosion resistance and good insulation performance. Then place the external working equipment on the top of the base bin 1. The user can make slots and holes in the base bin 1 or the protective frame 2 according to their own needs so that the lines of the external equipment can pass through normally. At the same time, one end of the wire 20 should be connected to the external battery or other power source equipment in advance, and the other end of the wire 20 should be connected to the external working equipment so that they are in series. This is a prior art and will not be elaborated on here. Then cover the protective frame 2 on the outer surface of the external equipment, and rotate the fastening screws 4 and insert them into the bottom sides of the protective frame 2 and the top of the base bin 1 at the same time, so that the base bin 1 and the protective frame 2 are fixed in position.

[0033] Finally, pull the handle 6 to slide the closed door 5 along the front of the protection frame 2 to seal the front of the protection frame 2. As the closed door 5 slides, the ball at the bottom end of the clamping column 15 rolls on the upper surface of the base bin 1. After the closed door 5 completely seals the front of the protection frame 2, the clamping column 15 is located directly above the clamping slot 10. Then move the movable plate 11 downward to make the energized iron plate 12 move downward with the movable plate 11. The energized iron plate 12 is inserted between the two groups of conductive plates 19. As the energized iron plate 12 is inserted, the conductive plate 19 is forced to move in the opposite direction and squeeze the conductive spring 18. At the same time, under the rebound action of the conductive spring 18, the two groups of conductive plates 19 tightly clamp the energized iron plate 12. After the energized iron plate 12 is inserted, the circuit is in a closed state. After that, the external working equipment can work normally. This is an existing physical technology and will not be elaborated here. At the same time, the clamping column 15 and the moving rod 13 will also move down with the moving plate 11. The bottom end of the clamping column 15 slides into the clamping slot 10, so that the closed door 5 will not slide easily. Finally, the limiting nut 14 is threadedly rotated and sleeved on the outer surface of the threaded ring at the top of the moving rod 13. The limiting nut 14 is blocked by the fixed plate 8 so that the moving plate 11 will not move up easily, ensuring that the energized iron plate 12 will not be separated from the middle of the two sets of conductive plates 19. According to the above steps, the reverse operation can be performed to pull out the energized iron plate 12, interrupt the circuit, and slide the closed door 5 to open. This is so that the staff can observe the working status of the internal equipment of the base compartment 1 at any time through the perspective window 7. The above is the entire working principle of the utility model.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
