[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the assembly and disassembly of the device are relatively cumbersome, and the overall idea is as follows: a DC screen with a busbar insulation function, comprising a DC screen frame body 1, a side end portion of the DC screen frame body 1 is provided with a sliding inlay groove 11, and the upper and lower inner walls of the sliding inlay groove 11 are provided with limiting grooves 12; wherein, a busbar connection box 13 is slidably installed inside the sliding inlay groove 11, and a fixed top cover 14 is slidably installed on the upper and lower sides of the busbar connection box 13; wherein, two fixed limiting rods 15 are fixedly installed on the upper and lower sides of the busbar connection box 13, and a rotating blocking block 16 is rotatably installed on the side end portion of each fixed limiting rod 15, and the fixed top cover 14 installed on the upper and lower sides of the busbar connection box 13 can achieve the effect of protecting the rotating blocking block 16 and other parts.

[0024] In view of the problems existing in the prior art, the utility model provides a DC screen with busbar insulation function, wherein the side end of each rotating blocking block 16 is rotatably installed with a linkage rod 17; wherein two sliding pull rods 18 are slidably installed on the side end of the busbar connection box 13, and the side end of each sliding pull rod 18 is fixedly installed with a reverse thrust hub 19; wherein, the side end of each reverse thrust hub 19 is connected to a linkage rod 17, and the side end of the reverse thrust hub 19 is installed with a spring, and the other side of the spring is connected to the inner wall of the busbar connection box 13, and by pulling the sliding pull rod 18, the reverse thrust hub 19 is driven to partially move so as to install the side end spring of the reverse thrust hub 19, so that after the device is used, the device itself can return to its original position by its own rebound.

[0025] A snap-in groove 2 is provided at the side end portion of the busbar connection box 13 on the same side as the side where the sliding pull rod 18 is installed; wherein, the linkage rod 17 parts are all installed between the fixed top cover 14 and the busbar connection box 13, and a busbar connection block 21 is slidably installed inside the snap-in groove 2, and a docking hole 22 is provided at the side end portion of the busbar connection block 21; wherein, a limit frame 23 is slidably installed inside the snap-in groove 2, and an insulating side plate 24 is fixedly installed inside the limit frame 23, and a pulling handle 25 installed on the side end of the limit frame 23 facilitates the subsequent disassembly and replacement of part of the limit frame 23.

[0026] A pulling handle 25 is fixedly installed on the side end of the limiting frame 23; wherein, the busbar connecting block 21 and the limiting frame 23 are installed in sequence in the card slot 2, there are six busbar connecting blocks 21, and there are seven limiting frames 23. By staggering the busbar connecting blocks 21 and the limiting frame 23, the device can protect the busbar and insulate it at the same time when in use.

[0027] Working principle:

[0028] The first step is that when the user is in use, the device is placed on a horizontal surface, the user picks up the busbar connection box 13, and installs two fixed limit rods 15 on the upper and lower sides of the busbar connection box 13, and then installs a rotating block 16 on the side end of each fixed limit rod 15, and then installs a linkage rod 17 on the side end of each rotating block 16, and then the user picks up two sliding rods 18, and slides the sliding rods 18 along the holes opened on the side ends of the busbar connection box 13 to the upper and lower sides, and then the user installs a reverse thrust hub 19 on the side end of each sliding rod 18 installed in the busbar connection box 13, and then connects the spring installed on the side end of the reverse thrust hub 19 to the inner wall of the busbar connection box 13, and then the user connects the side ends of each linkage rod 17 to the reverse thrust hub 19 The user then picks up the two fixed top covers 14 and installs them to the upper and lower sides of the busbar connection box 13 along the two holes above the busbar connection box 13. The user then places the DC screen frame body 1 to the specified position. The user then picks up the busbar connection box 13 and slides it into the sliding inlay groove 11 opened at the side end of the DC screen frame body 1. The user then installs the extending part of the rotating blocking block 16 into the limiting groove 12 opened inside the sliding inlay groove 11. The user then picks up the limiting frame 23 and installs the insulating side plate 24 inside the limiting frame 23. The user then installs the pulling handle 25 on the side end of the limiting frame 23. The user then alternately places the limiting frame 23 and the busbar connection block 21 in the clamping groove 2 opened at the side end of the busbar connection box 13.

[0029] In the second step, when the user needs to use the device, the user picks up the connecting busbar and inserts the busbar into the docking hole 22 opened at the side end of the busbar connecting block 21. At this time, the busbar is connected to the DC screen frame body 1 in conjunction with the busbar connecting box 13. Then, when the device is working, because each busbar connecting block 21 is installed with a limit frame 23 on both sides, and the insulating side plate 24 inside the limit frame 23 will insulate the busbars, the insulation strength of the device interface is improved to ensure the safety of the equipment. When the interface part needs to be repaired, the user pulls the sliding rod 18 , the sliding rod 18 drives the reverse thrust hub 19, thereby driving the linkage rod 17, and the linkage rod 17 then pulls the rotation blocking block 16 part, and the rotation blocking block 16 part rotates around the fixed limit rod 15 position, thereby rotating toward the inside of the busbar connection box 13, so as to slide the busbar connection box 13 part out of the sliding embedding groove 11. After the busbar connection box 13 part is separated, the user releases the sliding rod 18 part, and the sliding rod 18 will return to its original position with the cooperation of the spring installed on the side end of the reverse thrust hub 19, and the rotation blocking block 16 will be rotated out of the busbar connection box 13 again.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
