Description

Technical Field

[0001] The utility model relates to the field of bus ducts, and more specifically, to a bus duct with a cable limiting structure. Background Art

[0002] In some specific cases, cables are used instead of copper bars inside some bus ducts. For example, when there are high requirements for the flexibility of the bus duct, cables can better adapt to complex installation environments and changes in the routing of the lines. Also, in some renovation projects, due to space limitations or the influence of the original wiring, bus ducts using cables instead of copper bars may be easier to install and connect to the existing system. In addition, for some temporary power supply requirements or short-term use occasions, bus ducts using cables instead of copper bars can reduce costs and facilitate later removal. At the same time, if there are strict restrictions on the weight of the bus duct, cables are usually lighter than copper bars and can meet the requirements of lightweight.

[0003] However, when this type of bus duct is in use, the cables are prone to move and wind inside the duct, which not only affects the normal use of the cables but also may pose safety hazards. Therefore, some bus ducts are provided with partitions inside to store the cables separately to avoid the above situation. However, in most cases, the number of cables in the bus duct is small, and partitions may not be needed, or only a small number of partitions are required. At this time, the redundant partitions not only occupy the internal space of the bus duct but also affect the normal ventilation and heat dissipation inside the bus duct.

[0004] Therefore, in order to solve the above technical problems, this application proposes a bus duct with a cable limiting structure. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a bus duct with a cable limiting structure.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A bus duct with a cable limiting structure includes a bus duct main body. A plurality of through slots parallel to the bus duct main body are opened at the bottom of the bus duct main body. A baffle is installed at the bottom end of the bus duct main body, and the baffle can pass through the through slots and move up and down along the through slots. When the baffle descends to the lowest position, its top is exactly flush with the bottom surface of the bus duct main body and does not occupy the internal space of the bus duct. When the baffle enters the bus duct main body upward, the interior of the bus duct main body can be divided into multiple spaces to limit the cables.

[0007] Preferably, guide rails are fixedly connected to both sides of the bottom end of the bus duct main body. Both sides of the baffle near the bottom end are slidably connected to the guide rails through sliders to maintain the linear movement of the baffle through the sliders and the guide rails.

[0008] Preferably, a magnet A is fixedly connected to the bottom end of the guide rail through a connecting rod. Magnet Bs are bonded to both sides of the bottom end of the busbar trunk body located on both sides of the through groove. An iron plate is fixedly connected between the baffle and the slider to simply fix the position of the baffle when it moves to the uppermost or lowermost position.

[0009] Preferably, the top of the busbar trunk body is open, and a cover plate is arranged at the opening part. The top of the baffle is detachably connected to the cover plate, which can fix the baffle more firmly.

[0010] Preferably, screw A is welded to the periphery of the top of the busbar trunk body, through hole A for screw A to pass through is provided at the periphery of the top end of the cover plate, screw B is welded to both sides of the top end of the baffle, and through hole B for screw B to pass through is provided in the middle of the cover plate.

[0011] Preferably, limit grooves are provided on both sides of the top end of the busbar trunk body, and vertical blocks corresponding to the limit grooves are welded to both sides of the bottom end of the cover plate, which is convenient for quickly finding the installation position of the cover plate.

[0012] Preferably, heat dissipation grooves are provided on both sides of the busbar trunk body, and ventilation grooves are provided on the surface of the baffle to maintain air circulation with the outside.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, when the baffle is pushed to the uppermost position, the top end of the baffle is flush with the top surface of the busbar trunk body, and the top end of the iron plate contacts the magnet B, thereby fixing the position of the baffle at this place. At this time, the baffle divides the interior of the busbar trunk body into multiple spaces for classified storage of cables. The number of pushed-up baffles can be selected according to needs, so as to limit the cables while reducing the occupation of the internal space of the busbar trunk body, and at the same time facilitating the ventilation and heat dissipation inside the busbar trunk body, thus solving the problem in the background technology that in most cases, the number of cables in the busbar is small, and partitions may not be needed, or the number of partitions needed is small. At this time, the redundant partitions not only occupy the internal space of the busbar, but also affect the normal ventilation and heat dissipation inside the busbar;

[0015] 2. The ventilation grooves on the baffle of the utility model can ensure the air circulation between the spaces divided by the baffle, and together with the heat dissipation grooves for air circulation between the busbar trunk body and the outside, the heat inside the busbar trunk body can be discharged smoothly to avoid damage to the busbar trunk body due to overheating;

[0016] 3. The top of the busbar trunk of the present utility model is designed to be open, and a cover plate is provided at the opening part. Moreover, the top of the baffle is detachably connected to the cover plate. In this way, after the cover plate is installed, the baffle can be fixed to the cover plate to prevent the baffle from falling. At the same time, by releasing the fixation between the baffle and the cover plate, the baffle can be further lowered. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] As Figures 1-4 shown, the present utility model provides a busbar with a cable limiting structure, including a busbar trunk 1. A plurality of through grooves 2 parallel to the busbar trunk 1 are opened at the bottom of the busbar trunk 1. A baffle 3 is installed at the bottom end of the busbar trunk 1, and the baffle 3 can pass through the through groove 2 and move up and down along the through groove 2. When the baffle 3 descends to the lowest position, its top is exactly flush with the bottom surface of the busbar trunk 1, without occupying the internal space of the busbar. When the baffle 3 enters the busbar trunk 1 upward, the interior of the busbar trunk 1 can be divided into multiple spaces to limit the cables. Guide rails 4 are fixedly connected to both sides of the bottom end of the busbar trunk 1. Both sides of the baffle 3 near the bottom end are slidably connected to the guide rails 4 through slide blocks 5. A magnet A 6 is fixedly connected to the bottom end of the guide rail 4 through a connecting rod. Magnets B 7 are bonded to both sides of the bottom end of the busbar trunk 1 located at both sides of the through groove 2. An iron plate 8 is fixedly connected between the baffle 3 and the slide block 5.

[0024] In the initial state, the baffle 3 is at the lowest position, and at this time, its top surface is flush with the bottom surface of the busbar trunking body 1, so as not to occupy the internal space of the busbar trunking body 1, which is suitable for the busbar trunking with fewer cables assembled inside. At this time, the bottom end of the iron plate 8 is in contact with the magnet A6, so that the two adsorb each other to simply fix the baffle 3. When it is necessary to classify the cables inside the busbar trunking body 1, push the baffle 3 upward. The baffle 3 drives the slider 5 to move upward, and the slider 5 slides upward along the guide rail 4 to maintain the linear movement of the baffle 3. At the same time, the baffle 3 drives the iron plate 8 to move upward, so that it separates from the magnet A6. Push the baffle 3 to the uppermost position. At this time, the top end of the baffle 3 is flush with the top surface of the busbar trunking body 1, and the top end of the iron plate 8 is in contact with the magnet B7, so as to fix the position of the baffle 3 here. At this time, the baffle 3 divides the inside of the busbar trunking body 1 into multiple spaces to classify and store the cables. The number of baffles 3 pushed upward can be selected according to needs (the present utility model is not limited to the two baffles 3 in the attached drawings. When used in an actual large busbar trunking, more baffles 3 can be set for selection). Thus, while limiting the cables, the occupation of the internal space of the busbar trunking body 1 is reduced, and at the same time, it is also beneficial to the ventilation and heat dissipation inside the busbar trunking body 1 (the more baffles 3 there are inside the busbar trunking body 1, the greater the blockage and the greater the impact on heat dissipation).

[0025] Furthermore, heat dissipation grooves 16 are provided on both sides of the busbar trunking body 1, and ventilation grooves 17 are provided on the surface of the baffle 3. In this way, the ventilation grooves 17 on the baffle 3 can ensure the air circulation between the spaces separated by the baffle 3. Coupled with the heat dissipation grooves 16 for air circulation between the busbar trunking body 1 and the outside world, the heat inside the busbar trunking body 1 can be smoothly discharged to avoid damage to the busbar trunking body 1 caused by overheating.

[0026] Since the overall weight of the baffle 3 and the iron plate 8 is relatively heavy, simply adsorbed by the magnet B7, it is easy to fall off after a long time, resulting in the baffle 3 being unable to normally limit the cables inside the busbar trunking body 1. For this reason, the top of the busbar trunking body 1 of the present utility model is designed to be open, and a cover plate 9 is provided at the opening part. Moreover, the top of the baffle 3 is detachably connected to the cover plate 9. In this way, after the cover plate 9 is installed, the baffle 3 can be fixed to the cover plate 9 to avoid the baffle 3 from falling. At the same time, by releasing the fixation between the baffle 3 and the cover plate 9, the baffle 3 can be further lowered. The specific structure is as follows:

[0027] Screws A10 are welded around the top of the busbar trunk 1. Through holes A11 for the screws A10 to pass through are provided around the top of the cover plate 9. Screws B12 are welded to both sides of the top of the baffle 3. Through holes B13 for the screws B12 to pass through are provided in the middle of the cover plate 9. That is, the through holes A11 on the cover plate 9 are passed through the screws A10 on the busbar trunk 1. After insertion, turn the nut clockwise and install the nut on the screw A10. The nut slowly abuts against the top of the cover plate 9, and then the cover plate 9 can be fixed on the busbar trunk 1. At this time, for the baffle 3 that has completed the rising operation (at this time, the attracting iron block B simply fixes the baffle 3 that has completed the rising operation by adsorbing the iron plate 8), the screw B12 at its top just passes through the through hole B13 on the cover plate 9 (the number of through holes B13 is the same as the number of screws B12). Then turn the nut clockwise and install the nut on the screw B12. The nut moves downward along the screw B12 and slowly abuts against the top of the cover plate 9, thereby fixing the baffle 3 on the cover plate 9. On the contrary, remove the nut on the screw B12, and then the descending operation of the baffle 3 can be carried out.

[0028] Furthermore, limiting grooves 14 are provided on both sides of the top of the busbar trunk 1. Vertical blocks 15 corresponding to the limiting grooves 14 are welded to both sides of the bottom of the cover plate 9. That is, when installing the cover plate 9, the vertical blocks 15 can be inserted into the limiting grooves 14, so as to quickly find the installation position of the cover plate 9, which is convenient for the staff to carry out the installation operation. After all, when installing the cover plate 9 by aligning the through hole A11 with the screw A10, since the volume of the screw A10 is small and not easy to operate, and the through hole A11 is generally slightly larger than the screw A10 (for easy insertion), without limiting, the cover plate 9 is likely to shift slightly during installation, resulting in difficulty for the screw B12 to pass through the through hole B13.

[0029] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention; any ordinary technical personnel in the industry can smoothly implement the present invention according to the illustrations in the specification and the above description; however, any equivalent changes such as slight modifications, decorations and evolutions made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
