Description

Technical Field

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

[0002] Busbar trunking is a high-efficiency conductive device used in power system distribution and transmission. It uses metal as the conductor, encapsulated in a closed shell made of metal or insulating material, and achieves safe and stable power transmission through a rationally arranged busbar structure. Compared to traditional cables, busbar trunking has advantages such as high current carrying capacity, low voltage loss, convenient installation, and strong protective performance. It can adapt to the needs of large-capacity, high-density power distribution and is widely used in power supply systems of industrial plants, commercial buildings, data centers, and other places. It is an important power distribution device in modern electrical engineering.

[0003] Chinese patent CN214506473U discloses a variable busbar trunking. This variable busbar trunking allows for the adjustment of the busbar trunking body's position by sequentially pulling several tie rods outwards and rotating them 90 degrees to engage them with a locking block. This allows the insertion rods to disengage from the slots and remain disengaged. After adjusting the position of the busbar trunking body, the tie rods are rotated 90 degrees in sequence to insert them into the slots. Simultaneously, by pulling the busbar trunking body outwards and installing locking bolts through locking holes on the locking rods onto the inner wall of the support rods, the axial distance of the busbar trunking body can be adjusted.

[0004] Although the aforementioned variable busbar trunking can adjust the position and axial distance of the busbar trunking body, its angle is fixed and cannot be flexibly adjusted according to actual conditions. It is not suitable for connecting other conductive plates in different positions and has insufficient applicability. Utility Model Content

[0005] The purpose of this invention is to provide a variable busbar trunking system that effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A variable busbar trunking system includes mounting rods and a collar on their surface. The outer surface of the collar has an annular groove, and multiple slides are disposed inside the annular groove. Support rods are rotatably mounted on the outer surfaces of the slides. A first adjustment mechanism for locking the angle of the support rods is provided between the support rods and the slides. The busbar trunking body is mounted at the end of the support rods. A second adjustment mechanism for fixing the position of the slides is provided between the slides and the annular groove.

[0008] Therefore, by setting the first adjustment mechanism and the second adjustment mechanism, the horizontal angle of the main body of the busbar trunking and the angle relative to the mounting rod can be adjusted respectively, and the included angle between two adjacent main bodies of the busbar trunking can also be adjusted. Thus, the angle can be flexibly adjusted according to the actual situation, which is suitable for connecting other conductive sheets in different positions and has strong applicability.

[0009] Furthermore, the first adjustment mechanism includes an annular plate mounted on the surface of the slide block. The annular plate is coaxially positioned on the outer side of the support rod, and multiple insertion holes are arranged in a circular array on its surface. A U-shaped groove is formed inside the support rod, and a U-shaped rod is disposed inside the U-shaped groove. Both ends of the U-shaped rod extend to the outer side of the support rod, and the lower end of the U-shaped rod engages with the insertion holes. By inserting the lower end of the U-shaped rod into different insertion holes, the horizontal angle of the busbar trunking can be adjusted.

[0010] Furthermore, the second adjustment mechanism includes a plurality of first screw holes arranged in a ring array on the inner wall of the annular groove. A first fixing block is mounted on the outer surface of the slide, and a first bolt adapted to the first screw hole is mounted on the first fixing block. By screwing the first bolt into different first screw holes, the angle of the busbar trunking body relative to the mounting rod can be adjusted.

[0011] Furthermore, a spring is installed inside the U-shaped groove, with both ends of the spring connected to the inner wall of the U-shaped groove and the U-shaped rod, respectively. This ensures that the lower end of the U-shaped rod is stably inserted into the insertion hole and fixed in place, preventing it from easily coming loose.

[0012] Furthermore, a sliding rod is installed inside the U-shaped groove, and the U-shaped rod is slidably mounted on the sliding rod, with a spring sleeved on the outer surface of the sliding rod. This prevents the spring from deforming or twisting during use.

[0013] Furthermore, a pressure block is installed at the upper end of the U-shaped rod, and the surface of the pressure block is covered with a rubber pad. This reduces discomfort when pressing with the thumb and improves the user experience.

[0014] Furthermore, the surface of the mounting member is provided with multiple guide grooves along its length, and multiple second screw holes are arrayed inside the guide grooves. A second fixing block is provided on the inner wall of the collar at the guide groove, and a second bolt that matches the second screw hole is installed on the second fixing block. The front and rear positions of the busbar trunking body can be adjusted.

[0015] Furthermore, the inner walls on both sides of the annular groove are provided with sliding grooves, and the outer surfaces on both sides of the slide block are provided with sliders, which are disposed within the sliding grooves. This allows the slide block to slide in a ring within the annular groove, facilitating arbitrary adjustment of its position.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] This invention rotatably mounts the support rod on the slide block and locks its angle through the first adjustment mechanism, thereby adjusting the horizontal angle of the busbar trunking body. Furthermore, the second adjustment mechanism fixes the slide block in different positions within the annular groove, thereby adjusting the angle of the busbar trunking body relative to the mounting rod. The included angle between two adjacent busbar trunking bodies can also be adjusted. Therefore, the angle can be flexibly adjusted according to actual conditions, making it suitable for connecting other conductive sheets in different orientations and highly applicable.

[0023] 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.

[0024] Please see Figures 1-4This utility model provides a variable busbar trunking system, comprising a mounting rod 1 and a collar 2 on its surface. The outer surface of the collar 2 has an annular groove 201. Multiple slides 202 are disposed inside the annular groove 201. A support rod 203 is rotatably mounted on the outer surface of the slides 202. A first adjustment mechanism 3 for locking the angle of the support rod 203 is provided between the support rod 203 and the slides 202. A busbar trunking body 204 is mounted at the end of the support rod 203. A second adjustment mechanism 4 for fixing the position of the slides 202 is provided between the slides 202 and the annular groove 201.

[0025] When the horizontal angle of the busbar trunking body 204 needs to be adjusted, firstly, the angle of the support rod 203 is released through the first adjustment mechanism 3. Then, the support rod 203 is rotated to adjust the horizontal angle of the busbar trunking body 204. Finally, the first adjustment mechanism 3 is used to fix it in place. When the angle of the busbar trunking body 204 relative to the mounting rod 1 needs to be adjusted, firstly, the slide block 202 is released through the second adjustment mechanism 4. Then, the position of the slide block 202 in the annular groove 201 is adjusted. Finally, the second adjustment mechanism 4 is used to fix it in place. Thus, the angle of the busbar trunking body 204 relative to the mounting rod 1 can be adjusted, and the included angle between two adjacent busbar trunking bodies 204 can also be adjusted. Therefore, the angle can be flexibly adjusted according to the actual situation, which is suitable for connecting other conductive sheets in different positions and has strong applicability.

[0026] It is worth noting that the structure and usage of the support rod 203 are consistent with the same part in the comparative patent, so it will not be elaborated on here.

[0027] Preferably, the first adjusting mechanism 3 includes an annular plate 301 mounted on the surface of the slide block 202. The annular plate 301 is coaxially disposed on the outer side of the support rod 203, and a plurality of insertion holes 302 are distributed in an annular array on the surface of the annular plate 301. A U-shaped groove 303 is formed inside the support rod 203, and a U-shaped rod 304 is disposed inside the U-shaped groove 303. Both ends of the U-shaped rod 304 extend to the outer side of the support rod 203, and the lower end of the U-shaped rod 304 is inserted into the insertion hole 302.

[0028] When you hold the support rod 203 and press the upper end of the U-shaped rod 304 with your thumb, you can pull its lower end out of the socket 302, thereby releasing the angle fixation of the support rod 203. Then you can hold the support rod 203 and rotate it to adjust the angle of the busbar trunking body 204. After the angle is adjusted, you can reinsert the lower end of the U-shaped rod 304 into the corresponding socket 302 to complete the purpose of adjusting the horizontal angle of the busbar trunking body 204.

[0029] Preferably, the second adjustment mechanism 4 includes a plurality of first screw holes 401 arranged in a ring array on the inner wall of the annular groove 201, a first fixing block 402 is installed on the outer surface of the slide block 202, and a first bolt 403 adapted to the first screw hole 401 is installed on the first fixing block 402.

[0030] After the first bolt 403 is unscrewed, the slide block 202 can be released. At this time, the slide block 202 can be slid in the annular groove 201 to adjust the position of the busbar trunking body 204. Then, the first bolt 403 is screwed back into the corresponding first screw hole 401 to complete the purpose of adjusting the angle of the busbar trunking body 204 relative to the mounting rod 1.

[0031] Preferably, a spring 305 is provided inside the U-shaped groove 303, and the two ends of the spring 305 are respectively connected to the inner wall of the U-shaped groove 303 and the U-shaped rod 304.

[0032] The spring 305 applies an outward pushing force to the U-shaped rod 304, so that both ends of the U-shaped rod 304 are in an outward-pushing state when no external force is applied. Therefore, it can be ensured that the lower end of the U-shaped rod 304 is stably inserted into the insertion hole 302 for fixation and is not easy to come out.

[0033] Preferably, a slide bar 306 is installed inside the U-shaped groove 303, the U-shaped bar 304 is slidably installed on the slide bar 306, and the spring 305 is sleeved on the outer surface of the slide bar 306.

[0034] The slider 306 provides a guide for the spring 305, ensuring that it can only be compressed horizontally and preventing deformation or twisting during use.

[0035] Preferably, a pressure block 307 is installed at the upper end of the U-shaped rod 304, and a rubber pad is provided on the surface of the pressure block 307.

[0036] When the thumb presses on the pressure block 307, the contact area with the finger is increased, and the soft contact with the rubber pad reduces discomfort to the thumb and improves the user experience.

[0037] Preferably, the surface of the mounting rod 1 is provided with a plurality of guide grooves 5 along its length direction, and a plurality of second screw holes 501 are arranged in an array inside the guide grooves 5. A second fixing block 502 is provided on the inner wall of the collar 2 and located at the guide grooves 5. A second bolt 503 adapted to the second screw hole 501 is installed on the second fixing block 502.

[0038] After unscrewing the second bolt 503 from the second screw hole 501, the collar 2 can be slid on the mounting rod 1 to adjust the front and rear position of the busbar trunking body 204. Then, the second bolt 503 can be screwed into the corresponding second screw hole 501.

[0039] Preferably, the inner walls on both sides of the annular groove 201 are provided with sliding grooves 6, and the outer surfaces on both sides of the slide block 202 are provided with sliders 601, which are disposed in the sliding grooves 6.

[0040] The sliding groove 6 and the slider 601 allow the slide block 202 to slide in an annular groove 201, making it easy to adjust its position arbitrarily.
