Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a compact busbar that can be centrally installed. Background Technology

[0002] The compact busbar trunking features phase-to-phase and phase-to-shell connections that are tightly fitted together, enabling it to withstand significant electrical and thermal stresses and rapidly dissipate heat generated by the conductors. It boasts a high current-carrying capacity, and the joints are secured with insulated bolts. The use of double-connecting copper busbars effectively increases the contact area at the joints, significantly reducing temperature rise. The conductors are wrapped with flame-retardant cross-linked polyethylene heat-shrink tubing, providing strong insulation and preventing the release of toxic gases in the event of fire. The compact busbar trunking offers flexible and convenient interface design, allowing for a large number of sockets and strong versatility. Adjusting the location of electrical equipment does not require changes to the power supply system.

[0003] Chinese Utility Model Patent Publication No. CN 222464093 U discloses a centralized installation type of busbar trunking. This centralized installation type of busbar trunking is equipped with a vertical adjustment component. When assembling and extending multiple suspension adjustment mechanisms, the bolts can be locked to the contact plate first, then the bolts can be locked into the screw hole D, and finally the nut can be locked to the bolt. During the entire extension process, the stability of the suspension adjustment mechanism can be adjusted by first adjusting the telescopic rod. However, this design is not convenient for centralized and rapid installation of multiple busbar trunkings, and it is not convenient for adjusting the spacing between the mounting rod and the mounting sleeve according to different widths and numbers of busbar trunkings, resulting in poor practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a compact busbar trunking that can be centrally installed, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a compact busbar trunking that can be centrally installed, including a busbar trunking body and a second positioning bolt. The upper and lower ends of the busbar trunking body are provided with limit grooves. The upper and lower ends of the busbar trunking body are provided with connecting bottom rods of the same size as the limit grooves. Multiple limiting frames adapted to the busbar trunking body and serving as limit frames are slidably connected to the outer surface of the connecting bottom rods away from the center line. Side frames are inserted and installed at the two ends of the connecting bottom rods away from the center line. The side frames are fixedly installed with lifting components by the second positioning bolt.

[0006] The hoisting assembly includes a hoisting base, a positioning block is inserted and installed at one end of the hoisting base near the center point, and a profile rod is fixedly installed at the other end of the positioning block away from the hoisting base.

[0007] Preferably, the side of the hoisting base near the center point is provided with a positioning groove, and the hoisting base is installed by plugging in the positioning block through the positioning groove.

[0008] The above technical solution, through the design of the positioning groove and positioning block, facilitates the quick connection between the lifting base and the profile rod. It can play a positioning role during connection, avoiding easy displacement during installation. When it is necessary to inspect or replace the lifting components, rotate the second positioning bolt and then pull the positioning block out of the positioning groove. The operation is simple and quick.

[0009] Preferably, the inner surface of the limiting frame is provided with a slot that is adapted to the connecting bottom rod, the connecting bottom rod is adapted to the limiting frame, and the limiting frame is adapted to the busbar trunking body.

[0010] Through the above technical solution, the matching design of slot one and connecting base rod allows the limiting frame to slide smoothly along the connecting base rod, facilitating the adjustment of the limiting frame's position according to the actual installation requirements of the busbar trunking body. At the same time, the limiting frame is compatible with the busbar trunking body, effectively limiting the busbar trunking body and preventing it from shaking or shifting during installation or operation, thus ensuring the stability and reliability of the busbar trunking body installation. It also allows multiple busbar trunking bodies to be installed together, achieving dense installation and improving space utilization through the limiting and fixing of the limiting frame.

[0011] Preferably, the outer surface of the connecting base rod is provided with a plurality of positioning holes 1 distributed at equal intervals, and the outer surface of the limiting frame is threaded with a positioning bolt 1 that penetrates the limiting frame and extends into the positioning hole 1.

[0012] Through the above technical solution, the positioning hole one and positioning bolt one are set up to quickly fix the limiting frame on the upper side of the connecting base rod. After the limiting frame slides to the appropriate position, tighten the positioning bolt one so that it passes through the limiting frame and screws into the positioning hole one, thus firmly fixing the limiting frame to the connecting base rod. The equally spaced positioning holes one can meet the limiting requirements of different positions, making the installation of the limiting frame more flexible and diverse. It can not only effectively prevent the limiting frame from sliding on the connecting base rod and ensure the limiting effect of the limiting frame on the busbar trunking body, but also has a simple structure, is easy to operate, and is convenient for installation and maintenance.

[0013] Preferably, the connecting base rod has positioning holes two at both ends away from the center line, and the side frame has positioning holes three at both ends away from the center line. The positioning bolt two passes through the hoisting assembly, positioning holes two and three and extends to the outer surface of the connecting base rod.

[0014] Through the above technical solution, the combined use of positioning hole two, positioning hole three, and positioning bolt two achieves a secure connection between the side frame, connecting base rod, and lifting assembly. Positioning bolt two passes sequentially through the lifting assembly, positioning hole two, and positioning hole three, stably fixing the side frame and lifting assembly to both ends of the connecting base rod, which not only improves its stability but also facilitates its quick disassembly.

[0015] Preferably, the two ends of the side frame are provided with slots, and the slots are plugged into the two ends of the connecting base rod away from the center line.

[0016] Through the above technical solution, the insertion and installation method of slot 2 and connecting base rod allows the side frame to be conveniently and quickly installed at both ends of the connecting base rod. During installation, simply insert both ends of the connecting base rod into slot 2 to initially connect the side frame and the connecting base rod, and then further fix it with positioning bolt 2, which improves the installation efficiency.

[0017] Preferably, a lifting rod is fixedly installed at the other end of the profile rod away from the positioning block, and an installation plate is fixedly installed at the other end of the lifting rod away from the positioning block.

[0018] Through the above technical solution, the hanger is used to suspend the busbar trunking body, and the mounting plate can be easily connected to the installation foundation to realize the fixed installation of the busbar trunking body. The design of setting two lifting components at both ends of one side frame ensures the uniformity of force during the lifting of the busbar trunking body, can better bear the weight of the busbar trunking body, and prevents the busbar trunking body from tilting or deforming during the lifting process.

[0029] 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.

[0030] Example 1: As Figure 1-6 As shown, the present invention provides a compact busbar trunking that can be centrally installed, including a busbar trunking body 1 and a positioning bolt 2 13. The upper and lower ends of the busbar trunking body 1 are provided with limiting grooves 2. The upper and lower ends of the busbar trunking body 1 are provided with connecting bottom rods 3 of the same size as the limiting grooves 2. Multiple limiting frames 6 adapted to the busbar trunking body 1 and serving as limiting elements are slidably connected to the outer surface of the connecting bottom rods 3 away from the center line. Side frames 9 are inserted and installed at the two ends of the connecting bottom rods 3 away from the center line. The side frames 9 are fixedly installed with a hoisting assembly 12 by the positioning bolt 2 13.

[0031] The hoisting assembly 12 includes a hoisting base 1201. A positioning block 1203 is inserted and installed at one end of the hoisting base 1201 near the center point, and a profile rod 1204 is fixedly installed at the other end of the positioning block 1203 away from the hoisting base 1201.

[0032] Specifically, the lifting base 1201 has a positioning groove 1202 on the side near the center point. The lifting base 1201 is installed by plugging in the positioning block 1203 through the positioning groove 1202. The advantage is that the design of the positioning groove 1202 and the positioning block 1203 makes it easy to quickly connect the lifting base 1201 and the profile rod 1204. It can play a positioning role during connection and avoid easy displacement during installation. When it is necessary to inspect or replace the lifting assembly 12, the positioning bolt 13 is rotated and then the positioning block 1203 is pulled out from the positioning groove 1202. The operation is simple and quick.

[0033] Specifically, the inner surface of the limiting frame 6 is provided with a slot 7 that is adapted to the connecting base rod 3. The connecting base rod 3 is adapted to the limiting frame 6, and the limiting frame 6 is adapted to the busbar trunking body 1. The advantage is that the adaptation design of the slot 7 and the connecting base rod 3 allows the limiting frame 6 to slide smoothly along the connecting base rod 3, which makes it convenient to adjust the position of the limiting frame 6 according to the actual installation requirements of the busbar trunking body 1. At the same time, the adaptation of the limiting frame 6 to the busbar trunking body 1 can effectively limit the busbar trunking body 1, preventing the busbar trunking body 1 from shaking or displacing during installation or operation, ensuring the stability and reliability of the installation of the busbar trunking body 1. It also allows multiple busbar trunking bodies 1 to be installed together. Through the limiting and fixing of the limiting frame 6, dense installation is achieved, improving space utilization.

[0034] Specifically, the outer surface of the connecting base rod 3 has multiple equally spaced positioning holes 4, and the outer surface of the limiting frame 6 is threaded with a positioning bolt 8 that passes through the limiting frame 6 and extends into the positioning holes 4. The advantage is that the positioning holes 4 and positioning bolt 8 are designed to quickly fix the limiting frame 6 on the connecting base rod 3. When the limiting frame 6 slides to the appropriate position, tightening the positioning bolt 8 allows it to pass through the limiting frame 6 and screw into the positioning hole 4, thus firmly fixing the limiting frame 6 on the connecting base rod 3. The equally spaced positioning holes 4 can meet the limiting requirements of different positions, making the installation of the limiting frame 6 more flexible and diverse. It can not only effectively prevent the limiting frame 6 from sliding on the connecting base rod 3 and ensure the limiting effect of the limiting frame 6 on the busbar trunking body 1, but also has a simple structure, is easy to operate, and is convenient for installation and maintenance.

[0035] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, the connecting base rod 3 has positioning holes 2 5 at both ends away from the center line, and the side frame 9 has positioning holes 3 11 at both ends away from the center line. Positioning bolt 2 13 passes through the hoisting assembly 12, positioning holes 2 5 and 3 11, and extends to the outer surface of the connecting base rod 3. The advantage is that the combined use of positioning holes 2 5, positioning holes 3 11 and positioning bolt 2 13 achieves a firm connection between the side frame 9, the connecting base rod 3 and the hoisting assembly 12. Positioning bolt 2 13 passes through the hoisting assembly 12, positioning holes 2 5 and 3 11 in sequence, stably fixing the side frame 9 and the hoisting assembly 12 to both ends of the connecting base rod 3, which not only improves its stability but also facilitates its quick disassembly.

[0037] Specifically, slots 2 10 are provided at both ends of the side frame 9. The slots 2 10 and the ends of the connecting base rod 3 away from the center line are plugged in. The advantage is that the plugging installation method of the slots 2 10 and the connecting base rod 3 makes it easy and quick to install the side frame 9 at both ends of the connecting base rod 3. During installation, simply insert both ends of the connecting base rod 3 into the slots 2 10 to initially connect the side frame 9 and the connecting base rod 3, and then further fix it with the positioning bolts 2 13, which improves the installation efficiency.

[0038] Specifically, a hanger 1205 is fixedly installed at the other end of the profile rod 1204 away from the positioning block 1203, and an installation plate 1206 is fixedly installed at the other end of the hanger 1205 away from the positioning block 1203. Two identical lifting components 12 are provided at both ends of a side frame 9 away from the center line. The advantage is that the hanger 1205 is used to suspend the busbar trunking body 1, and the installation plate 1206 can be easily connected to the installation foundation to realize the fixed installation of the busbar trunking body 1. The design of setting two lifting components 12 at both ends of a side frame 9 ensures the uniformity of force during the lifting of the busbar trunking body 1, can better bear the weight of the busbar trunking body 1, and prevents the busbar trunking body 1 from tilting or deforming during the lifting process.

[0039] Working principle: During use, the upper and lower limit grooves 2 of the busbar trunking body 1 are fitted with the connecting base rod 3. The slot 7 on the surface of the connecting base rod 3 allows the limit frame 6 to slide flexibly. According to the installation requirements of the busbar trunking body 1, after the limit frame 6 is slid to the designated position, the positioning bolt 8 is tightened so that it is screwed into the positioning hole 4, fixing the limit frame 6. This limits the busbar trunking body 1, preventing it from shaking or shifting. Multiple busbar trunking bodies 1 can be installed in a concentrated and dense manner with the help of the limit frame 6, improving space utilization. The two ends of the connecting base rod 3 are inserted into the slot 10 of the side frame 9, initially completing the connection between the two. Then, the positioning bolt 13 passes through the hoisting component 12, the positioning hole 5, and the positioning hole 11 in sequence, firmly fixing the side frame 9 and the hoisting component 12 to the connecting base rod 3. At both ends of the base rod 3, in the hoisting assembly 12, the positioning block 1203 is inserted into the positioning groove 1202 of the hoisting seat 1201, realizing the quick and accurate connection between the hoisting seat 1201 and the profile rod 1204. This design can not only play a positioning role during installation to avoid installation deviation, but also facilitate the disassembly operation by rotating the positioning bolt 13 and pulling out the positioning block 1203 during maintenance or replacement of parts. The hoisting rod 1205 and the mounting plate 1206 at the other end of the profile rod 1204 are responsible for suspending and fixing the busbar trunking body 1 on the installation foundation. Each side frame 9 is equipped with a hoisting assembly 12 at both ends to ensure that the busbar trunking body 1 is subjected to uniform force during hoisting, avoid tilting and deformation, and ensure the stability and safety of the busbar trunking during installation and use.

[0040] 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.
