[0028] The following elaborates on the preferred embodiments of the present utility model in conjunction with the attached drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.
[0029] As Figures 1 - 3 shown, a busbar trunking system for low-voltage power transmission and distribution lines includes a copper bar 100. A plurality of holders 200 are evenly snap-connected to the outer wall of the copper bar 100. Each of the plurality of holders 200 includes a male head 201 and a female head 202, and they are in mutual cooperation. A plurality of card slots 203 are correspondingly provided on the opposite surfaces of the plurality of male heads 201 and female heads 202, and they are respectively snap-connected to the copper bar 100 through the card slots 203. Limit blocks 204 are symmetrically fixedly connected to the end faces of the plurality of male heads 201 and female heads 202. A convex block 205 and a groove 206 are respectively provided on the opposite surfaces of the plurality of male heads 201 and female heads 202. By inserting the convex block 205 on the male head 201 into the groove 206 inside the female head 202, the male head 201 and the female head 202 can be snap-fixed, thereby tightly snap-fixing the copper bar 100 arranged inside.
[0030] As Figures 2 - 4 shown, side frames 300 are symmetrically snap-connected to the end faces of the plurality of holders 200. The end faces of the plurality of holders 200 are respectively embedded inside the sleeves 301 fixedly connected to the opposite surfaces of the two side frames 300. Limit holes 302 are provided in the middle positions of the plurality of sleeves 301. Multiple groups of limit blocks 204 are in embedded snap-connection with the multiple limit holes 302. Multiple groups of ventilation slots 303 are evenly provided on the two side frames 300. By snap-connecting the two side frames 300 to the end faces of the holders 200 through the sleeves 301, the holders 200 can be snap-fixed, and by using the limit holes 302 to snap onto the limit blocks 204, the holders 200 combined by the male heads 201 and the female heads 202 are further snap-fixed.
[0031] As Figure 2 , Figure 4 and Figure 5As shown, end caps 400 are symmetrically clamped and connected to the end faces of two side frames 300. A plurality of discharge holes 401 are evenly formed inside the two end caps 400, and a plurality of copper bars 100 are respectively arranged in a penetrating and sleeved manner through the plurality of discharge holes 401. Positioning blocks 402 are fixedly connected to the opposite walls of the two end caps 400 near the corners. The plurality of positioning blocks 402 are respectively arranged in an embedded manner in the positioning holes 304 formed at the corners of the end faces of the two side frames 300. The plurality of positioning blocks 402 on the end caps 400 are used to engage with the positioning holes 304, so as to connect and fix the two side frames 300, and limit and fix the end faces of the copper bars 100 after installation, facilitating the connection and fixation of the two busbars.
[0032] As Figure 2 and Figure 6 shown, cover plates 500 are clamped and connected to the tops and bottoms of the two side frames 300 and the end caps 400. Connection components 600 are symmetrically sleeved on the side walls of the two cover plates 500 near the end faces. The connection component 600 includes two connection blocks 601 that are relatively slidably connected. Connection ports 602 are formed on the end faces of the two connection blocks 601. The two connection ports 602 are respectively sleeved on the connection shafts 501 fixedly connected to the side walls of the two cover plates 500 near the end faces, facilitating the connection and fixation of the covered cover plates 500 through the connection shafts 501 and the connection components 600. Bending portions 603 are arranged on the opposite faces of the two connection blocks 601. Slide rods 604 penetrate and slide on the opposite faces of the two bending portions 603 away from the middle positions. The end faces of the two slide rods 604 extend to the opposite faces of the two connection blocks 601. The end faces of the two springs 605 are respectively pressed against the two bending portions 603, facilitating the use of the compression and reset elasticity of the springs 605 to tightly tension and fix the cover plates 500 connected to the end faces by the two connection blocks 601. Springs 605 are wrapped around the outer walls of the two slide rods 604. The connection blocks 601 are sleeved and fixed to the connection shafts 501 through the connection ports 602. Thus, by using the reset elasticity of the internal springs 605, the two connection blocks 601 slide on the slide rods 604 through the bending portions 603, and further the two connection blocks 601 tightly tension and fix the cover plates 500 connected to the end faces.
[0033] When the utility model is in use, firstly, the convex block 205 on the male head 201 is inserted into the groove 206 inside the female head 202, so that the male head 201 and the female head 202 can be clamped and fixed, and thus the copper bar 100 arranged inside can be tightly clamped and fixed. Then, the two side frames 300 are clamped and connected to the end face of the clamping frame 200 through the sleeve frame 301, so that the clamping frame 200 can be clamped and fixed. And by using the limiting hole 302 to be clamped on the limiting block 204, the clamping frame 200 combined by the male head 201 and the female head 202 is further clamped and fixed. The multiple positioning blocks 402 on the end cover 400 are clamped with the positioning holes 304, so that the two side frames 300 can be connected and fixed, and the end face of the installed copper bar 100 is limited and fixed, which is convenient for connecting and fixing the two busbars. Then, the two cover plates 500 are respectively covered on the upper and lower parts, and the connecting block 601 is sleeved and fixed with the connecting shaft 501 through the connecting port 602. Thus, by means of the reset elasticity of the spring 605 inside, the two connecting blocks 601 slide on the sliding rod 604 through the bending part 603, and then the two connecting blocks 601 tightly tension and fix the cover plates 500 connected at the end face.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
