Description

Technical Field

[0001] This invention belongs to the field of busbar technology, and in particular relates to an angle-adjustable L-shaped busbar and its assembly method. Background Technology

[0002] Busbar trunking is a power distribution device used for centralized power distribution. It consists of a metal shell, conductive busbars, and insulating materials. It is mainly used to replace traditional cables for high current transmission in low-voltage or medium-voltage power distribution systems. It is usually made of copper or aluminum as the current carrier. The cross-sectional shape is mostly rectangular or groove-shaped. It wraps the conductive busbars and commonly uses polyester film, epoxy resin or fire-resistant materials to ensure insulation and heat resistance.

[0003] To facilitate connection, existing busbar trunking is designed in L-shape or Z-shape. These existing L-shaped and Z-shaped busbar trunking are usually integrated structures, but they cannot be used in some installation environments. The angle of the busbar trunking cannot be adjusted according to usage requirements, which limits its use. In addition, existing busbar trunking is hoisted to the installation site using an assembly frame, but the connection position between the assembly frame and the busbar trunking is fixed, and it is not possible to assemble it according to the installation environment.

[0004] To address these issues, we provide an angle-adjustable L-shaped busbar trunking and its assembly method. Summary of the Invention

[0013] The present invention is further configured such that the assembly structure includes an assembly base, the assembly base is fixedly installed on one side of the first busbar and the second busbar, the surface of the assembly base is provided with a sliding groove, the interior of the assembly base is provided with an adjustment groove, the adjustment groove is connected to the sliding groove, both sides of the upper end of the inner wall of the adjustment groove are provided with limit racks, and a movable plate is movably installed inside the sliding groove.

[0014] The invention is further configured such that a connecting screw is fixedly installed on the upper end of the movable plate, and limit grooves are formed on both sides of the surface of the connecting screw. A lifting rod is movably sleeved on the upper end of the connecting screw, and a rotating screw sleeve is sleeved on the surface of the connecting screw. The upper end of the rotating screw sleeve is rotatably connected to the lifting rod, and the rotating screw sleeve is threadedly connected to the connecting screw. Limit strips are provided on both sides of the inner wall of the lifting rod, and the limit strips are slidably connected to the limit grooves.

[0015] The invention is further configured such that connecting rods are movably inserted into both sides of the surface of the movable plate, the connecting rods are movably inserted into the interior of the adjusting groove, a clamping plate is fixedly installed at the lower end of the connecting rod, and limiting tooth blocks that engage with the limiting toothed rack are provided on both sides of the clamping plate, a connecting ring is fixedly installed at the upper end of the connecting rod, and an adjusting screw sleeve is sleeved on the surface of the connecting screw, the adjusting screw sleeve being rotatably connected to the connecting ring.

[0016] An assembly method for an angle-adjustable L-shaped busbar trunking includes the following steps:

[0017] S1. Rotate the double-threaded sleeve. Under the action of the thread, the support screw moves into the inside of the double-threaded sleeve as it rotates. The support screw drives the connecting frame to move. The connecting frame drives the connecting bar to move through the connecting bolt. The connecting bar drives the first busbar and the second busbar to rotate through the support frame.

[0018] S2. When the first busbar and the second busbar rotate, the first connecting piece, the second connecting piece, the first copper piece and the second copper piece rotate around the connecting rod, which can adjust the angle of the first busbar and the second busbar. During adjustment, the first busbar and the second busbar bend the insulating rubber sleeve.

[0019] S3. Place the main body of the busbar trunking at the installation location, rotate the adjusting screw sleeve, and the adjusting screw sleeve moves along the surface of the connecting screw rod. The adjusting screw sleeve drives the clamping plate to move through the connecting ring and the movable rod. The limiting teeth on both sides of the clamping plate disengage from the limiting rack, and the movable plate and the clamping plate can move inside the assembly base to adjust the position of the lifting rod. After adjustment, reverse the adjusting screw sleeve, and the clamping plate returns to its original position. The limiting teeth engage with the limiting rack to limit the position of the connecting screw rod and the lifting rod.

[0020] S4. Rotate the screw sleeve, and the rotating screw sleeve moves along the surface of the connecting screw rod. The rotating screw sleeve drives the lifting rod to move, adjusting the distance between the lifting plate and the main body of the busbar. The lifting plate fits against the wall at the installation location and is fixed with bolts.

[0021] The present invention has the following beneficial effects:

[0022] 1. In this invention, rotating the double-threaded sleeve causes the supporting screw to move inwards under the action of the thread. The supporting screw drives the connecting frame to move, and the connecting frame drives the connecting strip to move through the connecting bolt. The connecting strip drives the first busbar and the second busbar to rotate through the supporting frame. When the first busbar and the second busbar rotate, the first connecting piece, the second connecting piece, the first copper piece, and the second copper piece rotate around the connecting rod, which allows for angle adjustment of the first busbar and the second busbar. During adjustment, the first busbar and the second busbar bend the insulating rubber sleeve. At the same time, the threaded connection between the double-threaded sleeve and the supporting screw allows for pulling of the first busbar and the second busbar, preventing them from springing back after bending and affecting their use.

[0023] 2. In this invention, when the insulating rubber sleeve is bent, the clamping rod on one side is squeezed. The clamping rod moves along the guide rod through the moving block and compresses the clamping spring. The clamping rod on the other side moves with the bending of the insulating rubber sleeve under the action of the clamping spring and squeezes the surface of the insulating rubber sleeve, so that the insulating rubber sleeve can fit in close contact with the surface of the first busbar and the second busbar, thereby strengthening the protection of the connection between the first busbar and the second busbar.

[0024] 3. In this invention, when the user places the busbar trunking body at the installation location, they rotate the adjusting sleeve. The adjusting sleeve moves along the surface of the connecting screw rod. The adjusting sleeve drives the clamping plate to move through the connecting ring and connecting rod. The limiting teeth on both sides of the clamping plate disengage from the limiting rack. The moving plate and the clamping plate can move inside the assembly base to adjust the position of the lifting rod. After adjustment, the adjusting sleeve is reversed, and the clamping plate returns to its original position. The limiting teeth engage with the limiting rack, limiting the position of the connecting screw rod and the lifting rod. This facilitates adjusting the position of the lifting plate according to the installation location requirements. The user rotates the adjusting sleeve, which moves along the surface of the connecting screw rod. The rotating sleeve drives the lifting rod to move, adjusting the distance between the lifting plate and the busbar trunking body, facilitating the assembly of the busbar trunking body.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figures 1 to 4As shown, this embodiment provides an angle-adjustable L-shaped busbar trunking, including a busbar trunking body 100. The busbar trunking body 100 is composed of a first busbar 200, a second busbar 300, and an insulating rubber sleeve 400. The first busbar 200 has multiple first copper plates 210 inside, and the second busbar 300 has multiple second copper plates 310 inside. A connecting structure is provided between the first busbar 200 and the second busbar 300. The insulating rubber sleeve 400 is installed on the outside of the connecting structure. The connecting structure includes a first connecting piece 201 and a second connecting piece 301. The first connecting piece 201 is fixedly installed on both sides of one end of the first busbar 200, and the second connecting piece 301 is fixedly installed on both sides of one end of the second busbar trunking. The connecting piece 301 is rotatably connected. The first copper piece 210 and the second copper piece 310 are staggered. The connecting rod 120 is movably inserted on the surface of the first connecting piece 201, the second connecting piece 301, the first copper piece 210 and the second copper piece 310. Both ends of the connecting rod 120 are fitted with nuts 121. The first copper piece 210 and the second copper piece 310 are in contact with each other. An insulating gasket 122 is fitted on the surface of the connecting rod 120. The insulating gasket 122 is located between the two separate first copper pieces 210 and the second copper piece 310. The first copper piece 210, the second copper piece 310, the first connecting piece 201 and the second connecting piece 301 are located inside the insulating rubber sleeve 400. The two ends of the insulating rubber sleeve 400 are respectively fixedly fitted on one end of the first busbar 200 and the second busbar 300.

[0041] In this embodiment, when the first busbar 200 and the second busbar 300 rotate, the first connecting piece 201, the second connecting piece 301, the first copper piece 210, and the second copper piece 310 rotate around the connecting rod 120, allowing for angle adjustment of the first busbar 200 and the second busbar 300. The insulating rubber sleeve 400 facilitates protection of the connection between the first busbar 200 and the second busbar 300. The insulating gasket 122 prevents the first copper piece 210 and the second copper piece 310 from being connected in series, thus affecting the performance. The connecting rod 120 is limited by nuts 121 at both ends, which can be pulled out from the surface of the connecting rod 120. The connecting rod 120 can also be pulled out from inside the first copper piece 210, the second copper piece 310, the first connecting piece 201, and the second connecting piece 301, thereby facilitating the maintenance of the first busbar 200 and the second busbar 300.

[0042] like Figure 5 and Figure 6As shown, this embodiment provides an angle-adjustable L-shaped busbar trunking. An insulating rubber sleeve 400 has a clamping structure on its outer side. The clamping structure includes a fixing block 701, which is fixedly installed in the middle of both sides of the insulating rubber sleeve 400. A fixing strip 700 is fixedly installed on one side of the fixing block 701. Two clamping rods 710 are movably installed between the two fixing strips 700. The clamping rods 710 are located in the middle of both sides of the insulating rubber sleeve 400 and are slidably connected to the fixing strips 700. Moving grooves 702 are provided at both ends of one side of the fixing strips 700. A guide rod 720 is fixedly installed inside the moving groove 702. A moving block 721 is slidably installed inside the moving groove 702. The moving block 721 is movably sleeved on the surface of the guide rod 720. The moving block 721 is fixedly connected to both ends of the clamping rod 710. A clamping spring 722 connected to the moving block 721 is sleeved on the surface of the moving block 721.

[0043] In this embodiment, when the insulating rubber sleeve 400 bends, it compresses one side of the clamping rod 710. The clamping rod 710 moves along the guide rod 720 via the moving block 721, compressing the clamping spring 722. Under the action of the clamping spring 722, the clamping rod 710 on the other side moves with the bending of the insulating rubber sleeve 400, compressing the surface of the insulating rubber sleeve 400. This allows the insulating rubber sleeve 400 to fit against the surfaces of the first busbar 200 and the second busbar 300, strengthening the protection of the connection between the first busbar 200 and the second busbar 300.

[0044] like Figure 1 and Figure 2 As shown, this embodiment provides an angle-adjustable L-shaped busbar trunking. A support structure is provided between the first busbar 200 and the second busbar 300. The support structure includes a support frame 531, which is fixedly installed in the middle of one side of the first busbar 200 and the second busbar 300. A connecting strip 530 is movably installed on one side of the support frame 531. A connecting groove 532 is opened on the surface of the connecting strip 530. A connecting frame 520 is movably installed at one end of the connecting groove 532. A connecting bolt 521 is provided inside one end of the connecting frame 520. The connecting bolt 521 is movably inserted into the inside of the connecting groove 532. A support screw 510 is fixedly installed between the two connecting frames 520. A double-threaded sleeve 500 is rotatably installed between the two support screws 510. Anti-slip textures 501 are evenly provided on the outer side of the double-threaded sleeve 500.

[0045] In this embodiment, rotating the double-threaded sleeve 500 causes the support screw 510 to move inwards under the action of the thread. The support screw 510 drives the connecting frame 520 to move, and the connecting frame 520 drives the connecting bar 530 to move through the connecting bolt 521. The connecting bar 530 drives the first busbar 200 and the second busbar 300 to rotate through the support frame 531. At the same time, the threaded connection between the double-threaded sleeve 500 and the support screw 510 allows for the pulling of the first busbar 200 and the second busbar 300, preventing them from bending and springing back, which would affect their use.

[0046] like Figure 2 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, this embodiment provides an angle-adjustable L-shaped busbar trunking. An assembly structure is provided on one side of the busbar trunking body 100. The assembly structure includes an assembly base 110, which is fixedly installed on one side of the first busbar 200 and the second busbar 300. A sliding groove 111 is provided on the surface of the assembly base 110, and an adjustment groove 112 is provided inside the assembly base 110. The adjustment groove 112 is connected to the sliding groove 111. Limiting racks 113 are provided on both sides of the upper end of the inner wall of the adjustment groove 112. A movable plate 621 is movably installed inside the sliding groove 111. A connecting screw 620 is fixedly installed on the upper end of the movable plate 621. Limiting grooves 622 are provided on both sides of the surface of the connecting screw 620. A lifting rod 600 is movably sleeved on the upper end of the connecting screw 620. A rotating screw sleeve 640 is sleeved on the surface of the connecting screw 620. The upper end of 640 is rotatably connected to the lifting rod 600. The rotating sleeve 640 is threadedly connected to the connecting screw 620. Limiting strips 601 are provided on both sides of the inner wall of the lifting rod 600. The limiting strips 601 are slidably connected to the limiting grooves 622. The upper end of the lifting rod 600 is fixedly installed with a lifting plate 610. Lifting holes 611 are opened on both sides of the surface of the lifting plate 610. Connecting rods 120 are movably inserted on both sides of the surface of the moving plate 621. The connecting rods 120 are movably inserted into the interior of the adjusting groove 112. The lower end of the connecting rod 120 is fixedly installed with a clamping plate 633. Limiting tooth blocks 634 that engage with the limiting rack 113 are provided on both sides of the clamping plate 633. The upper end of the connecting rod 120 is fixedly installed with a connecting ring 630. The surface of the connecting screw 620 is fitted with an adjusting sleeve 631. The adjusting sleeve 631 is rotatably connected to the connecting ring 630.

[0047] In this embodiment, when the user places the busbar trunking body 100 at the installation location, rotating the adjusting sleeve 631 causes it to move along the surface of the connecting screw 620. The adjusting sleeve 631, through the connecting ring 630 and the connecting rod 120, drives the clamping plate 633 to move. The limiting teeth 634 on both sides of the clamping plate 633 disengage from the limiting rack 113, allowing the moving plate 621 and the clamping plate 633 to move within the mounting base 110, adjusting the position of the lifting rod 600. After adjustment, the adjusting sleeve 631 is reversed. The clamping plate 633 returns to its original position, and the limiting tooth block 634 engages with the limiting toothed rack 113 to limit the position of the connecting screw 620 and the lifting rod 600, so as to facilitate the adjustment of the position of the lifting plate 610 according to the installation position requirements. The user rotates the rotating sleeve 640, and the rotating sleeve 640 moves along the surface of the connecting screw 620. The rotating sleeve 640 drives the lifting rod 600 to move, adjusting the distance between the lifting plate 610 and the busbar trunking body 100, so as to facilitate the assembly of the busbar trunking body 100.

[0048] An assembly method for an angle-adjustable L-shaped busbar trunking includes the following steps:

[0049] S1. Rotate the double threaded sleeve 500. Under the action of the thread, the support screw 510 moves into the double threaded sleeve 500 as the double threaded sleeve 500 rotates. The support screw 510 drives the connecting frame 520 to move. The connecting frame 520 drives the connecting bar 530 to move through the connecting bolt 521. The connecting bar 530 drives the first busbar 200 and the second busbar 300 to rotate through the support frame 531.

[0050] S2. When the first busbar 200 and the second busbar 300 rotate, the first connecting piece 201, the second connecting piece 301, the first copper piece 210 and the second copper piece 310 rotate around the connecting rod 120, which can adjust the angle of the first busbar 200 and the second busbar 300. During adjustment, the first busbar 200 and the second busbar 300 bend the insulating rubber sleeve 400.

[0051] S3. Place the busbar trunking body 100 at the installation location, rotate the adjusting screw sleeve 631, and the adjusting screw sleeve 631 moves along the surface of the connecting screw rod 620. The adjusting screw sleeve 631 drives the clamping plate 633 to move through the connecting ring 630 and the movable rod 632. The limiting teeth 634 on both sides of the clamping plate 633 disengage from the limiting rack 113. The movable plate 621 and the clamping plate 633 can move inside the assembly base 110 to adjust the position of the lifting rod 600. After adjustment, reverse the adjusting screw sleeve 631, and the clamping plate 633 returns to its original position. The limiting teeth 634 engage with the limiting rack 113 to limit the position of the connecting screw rod 620 and the lifting rod 600.

[0052] S4. Rotate the rotating screw sleeve 640. The rotating screw sleeve 640 moves along the surface of the connecting screw rod 620. The rotating screw sleeve 640 drives the lifting rod 600 to move, adjusting the distance between the lifting plate 610 and the busbar trunking body 100. The lifting plate 610 fits against the wall at the installation location and is fixed with bolts.
