Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a rotatable busbar support structure. Background Technology

[0002] Busbar trunking is an electrical device used for power distribution and management, providing a convenient, safe, and flexible method for transmitting electricity. Its internal conductor bars are typically elongated structures with open tops and sides to accommodate the conductor bars and wires. The shape and size of the conductor bars are determined by the power load requirements and can be flat, round, or other special shapes. Busbar trunking is usually installed in walls, ceilings, or floors, offering flexible installation options; it can be recessed or surface-mounted.

[0003] Traditional busbar trunking is typically installed in a fixed position, lacking flexibility during installation, especially in complex environments where it requires numerous custom-made components, increasing costs and installation time. Furthermore, maintenance is difficult; the inability to adjust angles necessitates the disassembly of more components for maintenance, impacting system availability. There are also issues with thermal expansion and vibration, which traditional structures may not effectively handle, leading to loose connections or damage.

[0004] Chinese Utility Model Patent Publication No. CN 222191778 U discloses a support structure for busbar installation. This support structure stabilizes the busbar on the support structure by setting a busbar support component and a busbar fixing component on an adjusting frame. The height of the overall support system can be adjusted at will, improving the practicality of the overall device. The busbar support component uses springs to bind the upper and lower horizontal fixing blocks. When a busbar is installed, the upper horizontal fixing rod plays a certain role in compression and fixation, preventing the busbar from deviating during installation and facilitating subsequent busbar installation. Furthermore, when fixing the vertical fixing block, the busbar can be fine-tuned, improving the overall fault tolerance of the busbar installation and reducing installation error correction costs. However, this support structure for busbar installation does not have a rotation mechanism, making it difficult to quickly align connection points in narrow or non-standard spaces, thus increasing the installation difficulty and resulting in poor practicality. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a rotatable busbar support structure, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is as follows: a rotatable busbar support structure, including a busbar body, a connecting seat located above the busbar body, and a fixing plate located above the connecting seat. A rotating plate is provided on the side of the connecting seat away from the fixing plate. A through-type rotating groove and rotating hole are opened on the end of the rotating plate away from the connecting seat. A connecting column and rotating shaft are fixedly installed on the end of the connecting seat near the rotating plate. The connecting column and rotating shaft correspond one-to-one with the rotating groove and rotating hole. A support frame is provided on the side of the rotating plate away from the connecting seat. A sliding groove is opened on the inner side of the end of the support frame away from the rotating plate. A bidirectional screw is provided on the inner side of the sliding groove. A handwheel is fixedly installed on one end of the bidirectional screw. A clamping plate is threaded on the outer surface of the bidirectional screw. A slide rail is opened on the top of the inner side of the support frame.

[0007] Preferably, the fixed plate has an adjustment component fixedly installed at one end near the busbar trunking body, protrusions are fixedly installed on both sides of the rotating plate, a positioning column is fixedly installed at the end of the rotating plate away from the connecting seat, a locking nut threadedly connected to the positioning column is provided on the side of the support frame away from the rotating plate, and a rubber pad is adhesively installed on the surface of the clamping plate.

[0008] The above technical solution allows for easy adjustment of the support frame height by setting an adjustment component, and enables quick fixing of the support frame and the rotating plate by setting a locking nut. It also facilitates the disassembly of the support frame by staff later. The rubber pads bonded to the surface of the clamping plate can effectively protect the outer surface of the busbar trunking body and provide shock absorption.

[0009] Preferably, the adjustment assembly includes an adjustment frame, a limiting hole, an extension frame, a fixed base, a return spring, and a limiting post. The adjustment frame is fixedly installed at one end of the fixed plate near the busbar trunking body. Multiple sets of limiting holes are equally spaced on the outer side of the adjustment frame. The extension frame is slidably connected to the inner side of the adjustment frame. A fixed base is fixedly installed on the side of the extension frame near the fixed plate. A return spring is fixedly installed at one end of the fixed base near the limiting hole. A limiting post is fixedly installed at the end of the return spring away from the fixed base.

[0010] The above technical solution incorporates an adjustment component, allowing staff to easily adjust the height of the support frame according to on-site needs, adapting to different installation environments.

[0011] Preferably, the cross-section of the limiting post is the same as the cross-section of the limiting hole, and the limiting post can be inserted into the limiting hole.

[0012] With the above technical solution, when adjusting the support frame, the operator can squeeze the limiting post to make the limiting post retract into the inside of the adjusting frame. At this time, the return spring is squeezed inward, and the extension frame can slide in the adjusting frame through the sliding connection between the adjusting frame and the extension frame. When the appropriate position is reached, the limiting post is inserted into the corresponding limiting hole, and the return spring returns outward, thus realizing the quick adjustment and fixation of the support frame.

[0013] Preferably, the support frame has a groove for inserting and installing with a protrusion on the side near the rotating plate, and a positioning hole for positioning and installing with a positioning post on the side near the rotating plate.

[0014] The above technical solution, through the insertion and installation of protrusions and grooves and the positioning and installation of positioning posts and positioning holes, enables the rapid connection between the support frame and the rotating plate, avoids misalignment during installation, improves installation efficiency, and reduces installation difficulty.

[0015] Preferably, the side of the rotating plate away from the connecting seat is provided with an adjusting nut and a mounting nut that are threadedly connected to the connecting column and the rotating shaft, and the rotating hole and the rotating shaft are rotatably connected.

[0016] With the above technical solution, when the staff rotates the support frame, they only need to loosen the fixing of the adjusting nut and the connecting column. At this time, the rotating plate rotates along the rotating shaft. When adjusted to the position required by the staff, the adjusting nut and the connecting column are tightened to quickly fix the rotating plate. The rotatable design allows the device to flexibly adjust the angle and orientation to adapt to different installation environments or equipment layout requirements. At the same time, the rotating parts make the device easier to maintain, making it convenient for staff to quickly locate and repair faulty sections, while reducing interference with the overall structure during maintenance.

[0017] Preferably, the clamping plates are provided in two identical sets, and the two sets of clamping plates are symmetrically distributed on the support frame, with the bottom of the clamping plates slidably connected to the slide rail.

[0018] With the above technical solution, when installing the busbar trunking body, the busbar trunking body is installed on the support frame. Then, the operator manually rotates the handwheel to rotate the bidirectional screw. Through the threaded connection between the two sets of clamping plates and the bidirectional screw, the two sets of clamping plates can move in opposite directions. The bottom of the clamping plates is slidably connected to the slide rail, which can ensure the stability of the clamping plates in the support frame. The adjustable width design of the clamping plates can flexibly adjust the clamping width of the support frame to meet the size requirements of different busbar trunking bodies and reduce the customization and modification costs caused by specification differences.

[0019] Compared with the prior art, this utility model provides a rotatable busbar support structure, which has the following advantages:

[0020] 1. This rotatable busbar support structure, through the one-to-one correspondence between the rotating shaft and connecting column and the rotating groove and rotating hole, facilitates the quick connection between the rotating plate and the connecting seat. The adjusting nut is threadedly connected to the connecting column. When adjusting the angle of the rotating plate, simply loosening the adjusting nut and connecting column allows the rotating groove on the rotating plate to rotate under the guidance of the connecting column. When adjusted to the desired position, simply tightening the adjusting nut and connecting column quickly fixes the rotating plate. The rotatable design allows the device to flexibly adjust its angle and orientation. Simultaneously, the rotating components make the device easier to maintain, facilitating quick location and repair of faulty sections by staff, while reducing interference with the overall structure during maintenance.

[0021] 2. In this rotatable busbar support structure, when the operator adjusts the height of the support frame, the limit post can be squeezed to retract into the inner side of the adjustment frame. At this time, the return spring is squeezed inward, and the extension frame can slide in the adjustment frame through the sliding connection between the adjustment frame and the extension frame. When the appropriate position is reached, the limit post is inserted into the corresponding limit hole, and the return spring returns outward, thus realizing the quick adjustment and fixation of the support frame.

[0022] 3. This rotatable busbar support structure allows operators to manually rotate a handwheel to turn a bidirectional screw. Two sets of clamping plates are threadedly connected to the bidirectional screw, enabling the two sets of clamping plates to move in opposite directions. The bottom of the clamping plates is slidably connected to a slide rail, ensuring stability during movement within the support frame. Furthermore, the adjustable width of the clamping plates allows for flexible adjustment of the support frame's clamping width, meeting the size requirements of different busbar trunking bodies and reducing customization costs due to specification differences.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1: As Figure 1-8 As shown, the present invention provides a rotatable busbar support structure, including a busbar body 1, a connecting seat 4 located above the busbar body 1, and a fixing plate 3 located above the connecting seat 4. A rotating plate 5 is provided on the side of the connecting seat 4 away from the fixing plate 3. A through-type rotating groove 6 and a rotating hole 9 are opened on the end of the rotating plate 5 away from the connecting seat 4. A connecting column 10 and a rotating shaft 11 are fixedly installed on the end of the connecting seat 4 near the rotating plate 5. The connecting column 10 and the rotating shaft 11 correspond one-to-one with the rotating groove 6 and the rotating hole 9. A support frame 14 is provided on the side of the rotating plate 5 away from the connecting seat 4. A sliding groove 18 is opened on the inner side of the end of the support frame 14 away from the rotating plate 5. A bidirectional screw 19 is provided on the inner side of the sliding groove 18. A handwheel 20 is fixedly installed on one end of the bidirectional screw 19. A clamping plate 21 is threaded on the outer surface of the bidirectional screw 19. A slide rail 23 is opened on the top of the inner side of the support frame 14.

[0034] Specifically, an adjustment component 2 is fixedly installed at one end of the fixed plate 3 near the busbar trunking body 1. Protrusions 7 are fixedly installed on both sides of the rotating plate 5. A positioning post 8 is fixedly installed at the end of the rotating plate 5 away from the connecting seat 4. A locking nut 17, threadedly connected to the positioning post 8, is provided on the side of the support frame 14 away from the rotating plate 5. A rubber pad 22 is adhesively installed on the surface of the clamping plate 21. The advantages are that the adjustment component 2 facilitates the adjustment of the height of the support frame 14, the locking nut 17 enables quick fixing of the support frame 14 to the rotating plate 5, and also facilitates the disassembly of the support frame 14 by later personnel. The rubber pad 22 adhesively installed on the surface of the clamping plate 21 effectively protects the outer surface of the busbar trunking body 1 and provides shock absorption.

[0035] Specifically, the adjustment assembly 2 includes an adjustment frame 201, limiting holes 202, an extension frame 203, a fixed base 204, a return spring 205, and a limiting post 206. The adjustment frame 201 is fixedly installed on one end of the fixed plate 3 near the busbar trunking body 1. Multiple sets of limiting holes 202 are evenly spaced on the outer side of the adjustment frame 201. The extension frame 203 is slidably connected to the inner side of the adjustment frame 201. A fixed base 204 is fixedly installed on the side of the extension frame 203 near the fixed plate 3. A return spring 205 is fixedly installed on one end of the fixed base 204 near the limiting holes 202, and a limiting post 206 is fixedly installed on the end of the return spring 205 away from the fixed base 204. The advantage is that the adjustment assembly 2 allows workers to easily adjust the height of the support frame 14 according to on-site needs, adapting to different installation environments.

[0036] Specifically, the cross-section of the limiting post 206 is the same as that of the limiting hole 202, and the limiting post 206 can be inserted into the limiting hole 202. The advantage is that when adjusting the height of the support frame 14, the operator can squeeze the limiting post 206, causing it to retract into the inner side of the adjusting frame 201. At this time, the return spring 205 is pressed inward, and through the sliding connection between the adjusting frame 201 and the extension frame 203, the extension frame 203 can slide within the adjusting frame 201. When adjusted to the appropriate position, by inserting the limiting post 206 into the corresponding limiting hole 202, the return spring 205 returns outward, thus achieving rapid adjustment and fixation of the support frame 14.

[0037] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0038] Specifically, the support frame 14 has a groove 15 on the side near the rotating plate 5 for inserting and installing the protrusion 7, and a positioning hole 16 on the side near the rotating plate 5 for positioning and installing the positioning post 8. The advantage is that by setting the insertion and installation of the protrusion 7 and the groove 15, and the positioning and installation of the positioning post 8 and the positioning hole 16, a quick connection between the support frame 14 and the rotating plate 5 can be achieved, avoiding misalignment during installation, improving installation efficiency while reducing installation difficulty.

[0039] Specifically, the rotating plate 5, on the side away from the connecting seat 4, is provided with an adjusting nut 12 and a mounting nut 13 that are threadedly connected to the connecting column 10 and the rotating shaft 11. The rotating hole 9 is rotatably connected to the rotating shaft 11. The advantage is that when the operator rotates the support frame 14, they only need to loosen the fixing of the adjusting nut 12 to the connecting column 10. At this time, the rotating groove 6 on the rotating plate 5 rotates along the connecting column 10. When adjusted to the desired position, the adjusting nut 12 is tightened to the connecting column 10 to quickly fix the rotating plate 5. The rotatable design allows the device to flexibly adjust its angle and orientation to adapt to different installation environments or equipment layout requirements. At the same time, the rotating components make the device easier to maintain, facilitating quick location and repair of faulty sections, while reducing interference with the overall structure during maintenance.

[0040] Specifically, two identical sets of clamping plates 21 are provided, symmetrically distributed on the support frame 14. The bottom of the clamping plates 21 is slidably connected to the slide rail 23. The advantage is that when installing the busbar trunking body 1, it is mounted on the support frame 14, and then the operator manually rotates the handwheel 20 to rotate the bidirectional screw 19. Through the threaded connection between the two sets of clamping plates 21 and the bidirectional screw 19, the two sets of clamping plates 21 can move in opposite directions. The slidable connection between the bottom of the clamping plates 21 and the slide rail 23 ensures the stability of the clamping plates 21's movement on the support frame 14. Furthermore, the adjustable width design of the clamping plates 21 allows for flexible adjustment of the clamping width of the support frame 14, meeting the size requirements of different busbar trunking bodies 1 and reducing the cost of customized modifications due to specification differences.

[0041] Working Principle: In use, the support frame 14 and the rotating plate 5 are quickly connected by inserting the protrusion 7 into the groove 15 and positioning the positioning column 8 into the positioning hole 16. Then, the support frame 14 and the rotating plate 5 are quickly fixed by tightening the locking nut 17, facilitating later disassembly of the support frame 14. Before installing the busbar trunking body 1, workers can rotate the rotating plate 5 to adapt the busbar trunking body 1 to different installation environments or equipment layout requirements, depending on the site conditions. At this time, workers only need to loosen the fixing of the adjusting nut 12 and the connecting column 10. The rotating groove 6 on the rotating plate 5 then rotates along the connecting column 10. When adjusted to the desired position, simply tighten the adjusting nut 12 and the connecting column 10 to quickly fix the rotating plate 5. The rotatable design allows for flexible adjustment of angle and orientation, while the rotating components make the device easier to maintain, facilitating quick location and repair of faulty sections, and reducing interference with the overall structure during maintenance. Workers can adjust the height of the support frame 14... When adjusting the position, the limiting post 206 can be squeezed to retract into the inner side of the adjusting frame 201. At this time, the return spring 205 is pressed inward. Then, through the sliding connection between the adjusting frame 201 and the extension frame 203, the extension frame 203 can slide within the adjusting frame 201. When the position is adjusted to the appropriate position, the limiting post 206 is inserted into the corresponding limiting hole 202, and the return spring 205 returns outward, thus achieving quick adjustment and fixation of the support frame 14. Subsequently, the busbar trunking body 1 is installed on the support frame 14. Subsequently, the staff manually rotated the handwheel 20 to rotate the bidirectional screw 19. Through the threaded connection between the two sets of clamping plates 21 and the bidirectional screw 19, the two sets of clamping plates 21 can move in opposite directions. The bottom of the clamping plates 21 is slidably connected to the slide rail 23, which can ensure the stability of the clamping plates 21 in the movement of the support frame 14. Through the adjustable width design of the clamping plates 21, the clamping width of the support frame 14 can be flexibly adjusted to meet the size requirements of different busbar trunking bodies 1, and reduce the cost of customized modification due to specification differences.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
