Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a multi-layer dense busbar. Background Technology

[0002] Compact busbar trunking is suitable for AC three-phase four-wire and three-phase five-wire systems. It serves as an auxiliary equipment for power distribution equipment in industrial and mining enterprises and high-rise buildings. It is particularly suitable for workshops. Structurally, it adopts a "sandwich" compact assembly structure, in which the conductive bars of each phase, made of conductive materials such as copper or aluminum, are arranged in a specific phase and tightly fitted together. The outside is then tightly sealed and wrapped with a metal shell (usually steel plate or aluminum alloy).

[0003] According to the authorized patent 'CN221509069U', a double-layer dense busbar trunking includes a lower dense busbar trunking and an upper dense busbar trunking on top of the lower dense busbar trunking. Both sides of the top of the lower dense busbar trunking are bolted with lower bolts. The user can insert a rod into the threaded tube and then rotate the rod to rotate the threaded tube, causing the lower and upper bolts to move inside the threaded tube. This effectively facilitates adjusting the distance between the lower and upper dense busbar trunking. The user can hoist a second angle steel using expansion bolts, then support the lower and upper dense busbar trunking with the first angle steel, and then tighten the nut to limit the first angle steel. Excess length of the bolt can then be cut off, effectively facilitating the adjustment of the device's hoisting height.

[0004] In the process of using the above technical solution, the connecting structure on the outside of the screw is rotated to adjust the position of the busbar. However, due to the large frictional resistance between the screw and the collar, it is quite troublesome to adjust the busbar by rotating the screw, which reduces the efficiency of adjusting the position of the busbar and thus hinders the normal use of the rigid busbar.

[0005] Therefore, a multi-layer dense busbar trunking system is proposed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multi-layer dense busbar trunking to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multi-layer high-density busbar trunking includes a base, a support column fixedly connected to the top of the base, a busbar trunking body disposed on the outside of the support column, and an adjustment mechanism disposed between the busbar trunking body and the support column.

[0009] The adjustment mechanism includes a mounting plate, a sliding rod fixedly connected to the outer side of the mounting plate, a lifting groove opened inside the support column, an L-shaped plate fixedly connected to the side wall of the mounting plate, a movable tube fixedly connected to the outer side of the L-shaped plate, a moving rod movably connected inside the movable tube, a snap-fit ​​block fixedly connected to one end of the moving rod, a compression spring sleeved on the moving rod, and a positioning groove opened in the side wall of the support column.

[0010] As a further optimization of this utility model, an installation mechanism is provided between the mounting plate and the busbar trunking body. The installation mechanism includes a screw, a rotating cover is fixedly connected to the outside of the screw, and a threaded hole is provided in the side wall of the busbar trunking body.

[0011] As a further optimization of this utility model, the mounting plate is installed on the outside of the busbar trunking body, and the sliding rod is slidably engaged in the lifting groove inside the support column.

[0012] As a further optimization of this utility model, the L-shaped plates are symmetrically distributed on the outside of the mounting plate, and the moving rod is movably connected to the inside of the movable tube by a compression spring.

[0013] As a further optimization of this utility model, the snap-fit ​​block is located between the L-shaped plate and the side wall of the support column, and the snap-fit ​​block is adapted to the positioning groove.

[0014] As a further optimization of this utility model, the busbar trunking body is evenly distributed on the outer side of the support column, and the positioning groove is evenly distributed on the inner walls of both sides of the support column.

[0015] As a further optimization of this utility model, the screw is movable and symmetrically distributed inside the mounting plate, and the screw is adapted to the threaded hole in the side wall of the busbar trunking body.

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

[0017] In this invention, the height of the busbar trunking body can be flexibly adjusted through the set adjustment mechanism. The sliding rod on the outside of the mounting plate slides in the lifting groove of the support column. With the coordinated action of the L-shaped plate, movable tube, moving rod, snap-fit ​​block and positioning groove, the lifting and fixing of the busbar trunking body can be easily realized. The snap-fit ​​block is adapted to the positioning groove at different positions, and the busbar trunking body can be fixed at a suitable height according to actual needs, which greatly improves the flexibility of busbar trunking installation and facilitates adjustment according to wiring conditions and spatial layout.

[0027] 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.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figures 1-6 This utility model provides a technical solution:

[0030] A multi-layer dense busbar trunking includes a base 1, a support column 2 fixedly connected to the top of the base 1, a busbar trunking body 3 disposed on the outside of the support column 2, and an adjustment mechanism 4 disposed between the busbar trunking body 3 and the support column 2.

[0031] The adjustment mechanism 4 includes a mounting plate 41, a sliding rod 42 fixedly connected to the outer side of the mounting plate 41, a lifting groove 43 opened inside the support column 2, an L-shaped plate 44 fixedly connected to the side wall of the mounting plate 41, a movable tube 45 fixedly connected to the outer side of the L-shaped plate 44, a moving rod 46 movably connected inside the movable tube 45, a snap-fit ​​block 47 fixedly connected to one end of the moving rod 46, a compression spring 48 sleeved on the moving rod 46, and a positioning groove 49 opened in the side wall of the support column 2.

[0032] Furthermore: the mounting plate 41 is installed on the outside of the busbar trunking body 3, the sliding rod 42 is slidably engaged in the lifting groove 43 inside the support column 2, the L-shaped plate 44 is symmetrically distributed on the outside of the mounting plate 41, the moving rod 46 is movably connected to the inside of the moving tube 45 through the compression spring 48, the engaging block 47 is located between the L-shaped plate 44 and the side wall of the support column 2, and the engaging block 47 is adapted to the positioning groove 49. The busbar trunking body 3 is evenly distributed on the outside of the support column 2, and the positioning groove 49 is evenly distributed in the inner walls on both sides of the support column 2.

[0033] It should be noted that: the base 1 is the foundation, the top fixed support column 2 is the core support component, and the busbar trunking body 3 is installed on the outside of the support column 2 through the adjustment mechanism 4, realizing a multi-layered layout. This design can effectively save installation space and improve space utilization.

[0034] Specifically: The surface of the slide bar 42 is usually polished to reduce the frictional resistance between it and the lifting groove 43, making the lifting of the mounting plate 41 smoother. At the same time, the inner wall of the lifting groove 43 may be coated with a wear-resistant coating, such as a polytetrafluoroethylene coating, to further improve the wear resistance of both and avoid jamming after long-term use.

[0035] As a further implementation of this solution, an installation mechanism 5 is provided between the mounting plate 41 and the busbar trunking body 3. The installation mechanism 5 includes a screw 51, a rotating cover 52 is fixedly connected to the outside of the screw 51, and a threaded hole 53 is provided in the side wall of the busbar trunking body 3.

[0036] Furthermore, the screws 51 are movable and symmetrically distributed inside the mounting plate 41, and the screws 51 are adapted to the threaded holes 53 in the side wall of the busbar trunking body 3.

[0037] It should be noted that the thread accuracy of the screw 51 and threaded hole 53 in the mounting mechanism 5 directly affects the tightness of the connection. To prevent loosening, the thread surface will be treated with anti-loosening agents, such as applying thread-locking adhesive or using a fine thread design. The outer side of the rotating cover 52 is usually provided with anti-slip texture to facilitate rotation by the operator. At the same time, its material may be engineering plastic, which is both lightweight and has a certain strength, and can also play an insulating role.

[0038] Workflow: In terms of the operation of the adjustment mechanism 4, when it is necessary to adjust the height of the busbar trunking body 3, since the moving rod 46 is movably connected to the inside of the moving tube 45 through the compression spring 48, the moving rod 46 can be pulled outward first, so that the compression spring 48 is compressed, thereby causing the locking block 47 to disengage from the positioning groove 49 on the side wall of the support column 2. At this time, the sliding rod 42 on the outside of the mounting plate 41 can slide freely in the lifting groove 43 inside the support column 2. Pushing the mounting plate 41 can drive the busbar trunking body 3 to rise and fall. When the busbar trunking body 3 reaches the appropriate height, the moving rod 46 is released, and the elastic force generated by the reset of the compression spring 48 will push the moving rod 46 to move towards the support column 2, so that the locking block 47 is re-locked into the positioning groove 49 at the corresponding position, thereby fixing the mounting plate 41 and the busbar trunking body 3 at this height. Among them, the L-shaped plate 44 is symmetrically distributed on the outside of the mounting plate 41, providing a stable installation base for the moving tube 45 and the moving rod 46, ensuring the smoothness of the adjustment process.

[0039] For the installation mechanism 5, when installing the busbar trunking body 3, the busbar trunking body 3 is attached to the outside of the mounting plate 41, so that the threaded hole 53 on the side wall of the busbar trunking body 3 corresponds to the position of the screw 51 on the mounting plate 41. Then, the rotating cover 52 on the outside of the screw 51 is rotated to drive the screw 51 into the threaded hole 53. Through the threaded connection between the screw 51 and the threaded hole 53, the busbar trunking body 3 is firmly installed on the mounting plate 41. If it is necessary to disassemble the busbar trunking body 3, the rotating cover 52 is rotated in the opposite direction to unscrew the screw 51 out of the threaded hole 53. The operation is simple and efficient.

[0040] In addition, the busbar trunking body 3 is evenly distributed on the outside of the support column 2, the positioning grooves 49 are evenly distributed on the inner walls of both sides of the support column 2, and the screws 51 are movable and symmetrically distributed inside the mounting plate 41. These structural designs ensure that the busbar trunking is subjected to balanced forces, and while achieving flexible adjustment and convenient installation, they also ensure the stability and reliability of the busbar trunking during power transmission.

[0041] 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.
