[0028] Based on the above-mentioned structure, the high-stability busbar duct plug-in box is composed of a busbar duct body 100, a plug-in box body 300 and two accessories 200, wherein: Figure 2As shown, the top of the bus duct body 100 is provided with an opening for the pins on the back of the plug-in box body 300 to extend and plug in, so as to realize the electrical connection between the plug-in box body 300 and the bus duct body 100. The two accessories 200 are used for positioning and installing the plug-in box body 300 on the bus duct body 100. Specifically, during the installation process, the operator first inserts the pins on the back of the plug-in box body 300 into the opening at the top of the bus duct body 100. After pre-positioning the installation position of the plug-in box body 300 on the bus duct body 100, the operator can The two accessories 200 are installed separately. Taking the installation of one of the accessories 200 as an example, the operator first uses the two nuts 220 to install the two holders 230 in the two strip holes 250 in turn, and installs the first screw rod 240 through the middle of the support rod 210. Then, the operator clamps the entire assembled accessory 200 on one side of the plug-in box body 300 on the bus duct body 100, and adjusts the positions of the two holders 230 in the two strip holes 250, so that the bottoms of the two holders 230 are clamped on the two sides of the top of the bus duct body 100. Then, the operator The operator adjusts the position of the accessory 200 so that the first screw rod 240 is aligned with the limiting groove 320, and screws down the first screw rod 240 so that the bottom end of the first screw rod 240 is pressed against the limiting groove 320. Then, the operator can tighten the two nuts 220 and further screw down the first screw rod 240 to ensure that the accessory 200 is mounted on the bus duct body 100 and the accessory 200 is positioned firmly and firmly on the diagonal iron 310. Finally, the operator can follow the above steps to complete the assembly of the two accessories 200 on the bus duct body 100 in sequence, thereby completing the stability of the plug-in box body 300 on the bus duct body 100. Assembly, the high-stability bus duct plug-in box can realize the assembly of the plug-in box body 300 on the bus duct body 100 through two accessories 200 separately set from the plug-in box body 300, and with the help of the mutually adapted first screw 240 and the limit groove 320, the installation of the accessory 200 on the bus duct body 100 and the positioning and fixing of the plug-in box body 300 can be conveniently realized, and the operation is convenient. In addition, the two strip holes 250 opened on the support rod 210 are used to facilitate the installation and debugging of the operator. At the same time, the plug-in box body 300 can be adapted to the assembly operation on bus duct bodies 100 of various specifications.

[0029] Furthermore, the holder 230 includes a square column 2310 and a clamping joint 2330 fixedly installed at the bottom of the square column 2310 by means of screws 2320. The top of the square column 2310 is provided with a threaded column 2340 threadably matched with the nut 220. A gap is left between one side of the clamping joint 2330 and the square column 2310 for accommodating the top side of the bus duct body 100. The holder 230 can be clamped at the bottom to the top side of the bus duct body 100 by means of a preset gap between one side of the clamping joint 2330 and the square column 2310. Preferably, the middle part of the holder 230 is set as the square column 2310. On the one hand, during the position debugging process, it is convenient for the holder 230 to fit and position with the top side of the bus duct body 100. On the other hand, Figure 3 As shown, both sides of the support rod 210 are arranged as flange structures extending vertically downward. With the help of the two flange structures, a slide groove structure for sliding adaptation of the top of the square column 2310 can be formed, which facilitates the debugging and installation of the base 230 at the bottom of the support rod 210.

[0030] Furthermore, a positioning groove 2350 is provided at the top of the clamping joint 2330 for the bottom end of the square column 2310 to accommodate.

[0031] Furthermore, an anti-slip pattern 2360 is provided on the inner side of one side of the clamping joint 2330 , and a second screw 2370 is passed through the outer thread of the bottom of the square column 2310 .

[0032] Among them, the clearance of the clamping seat 230 used for clamping cooperates with the second screw 2370, so that the inner side of one side of the clamping joint 2330 can fit with the inner side of the top side of the bus duct body 100, and the setting of the anti-slip pattern 2360 further ensures that the clamping seat 230 is firmly and firmly clamped to the top side of the bus duct body 100. Since the anti-slip pattern 2360 is arranged on the inner side of one side of the clamping joint 2330, as a preference, the clamping joint 2330 and the square column 2310 are separated and arranged to facilitate the processing of the anti-slip pattern 2360, and the setting of the positioning groove 2350 helps to position and assemble the clamping joint 2330 at the bottom end of the square column 2310.

[0033] Furthermore, the limiting groove 320 is set as a strip groove structure distributed along the length direction of the angle iron 310, and each accessory 200 is equipped with two first screw rods 240, and the bottom ends of the two first screw rods 240 are respectively pressed and accommodated at the two ends of the strip groove structure. Among them, the first screw rod 240 vertically threads through the support rod 210, and the bottom end of the first screw rod 240 is pressed and accommodated in the limiting groove 320, so as to realize the positioning of the angle iron 310 on one side of the bus duct body 100 by the accessory 200. As a preferred embodiment, by setting the limiting groove 320 as a strip groove structure, and cooperating with the bottom ends of the two first screw rods 240 to be pressed and accommodated at the two ends of the strip groove structure, the reliability of the positioning and fixing of the angle iron 310 by the accessory 200 can be further improved.
