Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a busbar with flame-retardant function. Background Technology

[0002] Busbar trunking is a busbar system composed of a metal plate (steel or aluminum plate) as a protective shell, conductive bars, insulation materials, and related accessories. It can be manufactured as a plug-in type enclosed busbar with plug-in junction boxes at intervals, or as a feeder type enclosed busbar without junction boxes in the middle. In the power supply systems of high-rise buildings, power and lighting circuits are often installed separately, and busbar trunking, as the main power supply line, is installed vertically along the wall in the electrical shaft, one or more times.

[0003] Chinese Utility Model Patent Publication No. CN222441319U discloses a busbar trunking with flame-retardant function. This busbar trunking uses a cooling fan to blow air outwards, accelerating the discharge of hot air and improving heat dissipation, thus extending the lifespan of cables. The insulation layer reduces the impact of heat transmitted by the busbar trunking on the surrounding environment, lowering the risk of fire and improving the safety of the electrical system. The flame-retardant board is filled with flame retardant, effectively inhibiting the spread of flames in the event of a fire. However, this flame-retardant busbar trunking lacks an installation structure for connection ports, making maintenance difficult after prolonged use. Furthermore, the lack of a sealing mechanism makes the copper busbars prone to leakage and damage in humid environments, resulting in poor practicality and hindering widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a busbar trunking with flame-retardant function. It can effectively solve the problems of existing technologies, such as the lack of a design for connection ports in the installation structure, the inconvenience of maintenance after long-term use, the lack of a sealing mechanism, the easy leakage and damage of copper busbars in humid environments, poor practicality, and the inconvenience of promotion and use.

[0005] The technical solution adopted by this utility model is as follows: a busbar trunking with flame-retardant function, including a busbar trunking body and a connection port. A positioning block and a plug are fixedly installed at one end of the connection port near the busbar trunking body. An installation groove is opened on the outer side of the plug. A sealing ring is provided inside the installation groove. A locking component is provided between the busbar trunking body and the connection port. An installation seat one and an installation seat two are fixedly installed inside the busbar trunking body. A flame-retardant partition plate and a copper busbar are provided between the installation seat one and the installation seat two. Guide blocks are fixedly installed at both ends of the flame-retardant partition plate. A guide groove is opened on the side of the installation seat one and the installation seat two near the flame-retardant partition plate. An installation groove two and a threaded hole one are opened on the outer side of the busbar trunking body. A heat-conducting plate is provided on the outer side of the busbar trunking body. A threaded hole two is opened on the outer side of the heat-conducting plate. A bolt is threadedly connected to the outer side of the heat-conducting plate. Heat dissipation fins are fixedly installed on the outer side of the heat-conducting plate away from the busbar trunking body.

[0006] Preferably, the busbar trunking body has a positioning groove and a slot at one end near the connection port, the positioning block and the positioning groove are plugged in, and the plug and the slot are plugged in.

[0007] Using the above technical solution, workers can quickly position the connection port by inserting the positioning block into the positioning groove and the insert block into the slot.

[0008] Preferably, the locking assembly includes a movable groove, a limiting block, a spring, a pull rod, a fixed block, a first slot, a rotating plate, a second slot, and a limiting groove. The limiting block is slidably connected inside the movable groove. A spring and a pull rod are fixedly installed on the outside of the limiting block. A fixed block is fixedly installed at the end of the pull rod away from the limiting block. A first slot is formed on the outside of the fixed block. A rotating plate is rotatably installed on the outside of the busbar trunking body. A second slot is formed at the end of the rotating plate away from the busbar trunking body. A limiting groove is formed on the outside of the positioning block. The limiting block and the limiting groove are adapted to each other. The first slot and the second slot are adapted to each other.

[0009] Through the above technical solution, during the process of quickly positioning the connection port, when the limiting block contacts the positioning block, the spring contracts, and the limiting block moves into the interior of the movable groove. When the positioning block is completely submerged in the interior of the positioning groove, the spring rebounds, pushing the limiting block into the interior of the limiting groove, thus enabling the quick installation of the connection port. When it is necessary to disassemble the connection port, pull the lever, and then rotate the rotating plate so that the first slot engages with the second slot, and then pull out the connection port, thus enabling the quick disassembly of the connection port.

[0010] Preferably, the sealing ring is a rubber ring, and three identical sealing rings are provided, with the three sealing rings distributed at equal intervals.

[0011] Through the above technical solution, because the rubber ring has good sealing performance, the design of the sealing ring prevents humid air from entering the interior of the busbar trunking in a humid environment, thus avoiding leakage damage to the copper busbars. The sealing performance is high, and the design of three sealing rings further improves the overall sealing performance.

[0012] Preferably, the guide block and the guide groove are plugged in, the cross-section of the guide block is T-shaped, and the flame-retardant partition plate is a magnesium plate.

[0013] Using the above technical solution, workers can quickly install the flame-retardant partition plate by inserting the guide block into the guide groove. The magnesium plate has good fire resistance and can effectively prevent the spread of fire and delay the spread of fire.

[0014] Preferably, the heat-conducting plate and the second mounting groove are plugged in, and the bolt extends through the second threaded hole into the interior of the first threaded hole. The second threaded hole and the first threaded hole have the same diameter.

[0015] Using the above technical solution, the staff inserts the heat-conducting plate into the interior of the second mounting slot, and then inserts the bolt through the second threaded hole to the interior of the first threaded hole, which can realize the rapid installation of the heat-conducting plate. After long-term use, it is easy to clean and replace it.

[0016] Preferably, the heat dissipation fins are provided in multiple identical manner, and the multiple heat dissipation fins are distributed at equal intervals.

[0017] The above technical solution utilizes the heat dissipation fin design. Cool air is blown onto the surface of the heat dissipation fins, carrying away the heat from the surface of the fins, thus achieving rapid heat dissipation of the copper busbar. The design of multiple heat dissipation fins further improves the overall heat dissipation performance, preventing the copper busbar from working in a high-temperature environment for a long time, which could lead to damage. It is highly practical.

[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:

[0031] like Figure 1-7 As shown, this utility model provides a busbar trunking with flame-retardant function, including a busbar trunking body 1 and a connection port 2. A positioning block 5 and a plug 6 are fixedly installed at one end of the connection port 2 near the busbar trunking body 1. An installation groove 7 is provided on the outer side of the plug 6, and a sealing ring 8 is provided inside the installation groove 7. A locking component 9 is provided between the busbar trunking body 1 and the connection port 2. A mounting base 10 and a mounting base 11 are fixedly installed inside the busbar trunking body 1, and a flame-retardant partition is provided between the mounting base 10 and the mounting base 11. The plate 12 and copper busbar 13 are provided. Guide blocks 14 are fixedly installed at both ends of the flame-retardant partition plate 12. Guide grooves 15 are opened on the side of the mounting base 10 and mounting base 11 near the flame-retardant partition plate 12. Mounting groove 16 and threaded hole 17 are opened on the outer side of the busbar body 1. A heat-conducting plate 18 is provided on the outer side of the busbar body 1. Threaded hole 19 is opened on the outer side of the heat-conducting plate 18. Bolts 20 are threadedly connected to the outer side of the heat-conducting plate 18. Heat dissipation fins 21 are fixedly installed on the outer side of the heat-conducting plate 18 away from the busbar body 1.

[0032] Specifically, the busbar trunking body 1 has a positioning groove 3 and a slot 4 at one end near the connection port 2. The positioning block 5 is inserted into the positioning groove 3, and the plug block 6 is inserted into the slot 4. The advantage is that the operator can quickly position the connection port 2 by inserting the positioning block 5 into the positioning groove 3 and the plug block 6 into the slot 4 at the same time.

[0033] Specifically, the locking assembly 9 includes a movable groove 901, a limiting block 902, a spring 903, a pull rod 904, a fixing block 905, a first slot 906, a rotating plate 907, a second slot 908, and a limiting groove 909. The movable groove 901 is internally connected to the limiting block 902. The spring 903 and the pull rod 904 are fixedly installed on the outside of the limiting block 902. The end of the pull rod 904 away from the limiting block 902 is fixedly installed with the fixing block 905. The first slot 906 is opened on the outside of the fixing block 905. The rotating plate 907 is rotatably installed on the outside of the busbar trunking body 1. The second slot 908 is opened on the end of the rotating plate 907 away from the busbar trunking body 1. The positioning block 5 has a limiting groove 909 on its outside. The limiting block 902 is adapted to the limiting groove 909, and the first slot 906 is adapted to the second slot 908. The advantage is that during the process of quickly positioning the connection port 2, when the limiting block 902 contacts the positioning block 5, the spring 903 contracts, and the limiting block 902 moves into the interior of the movable groove 901. When the positioning block 5 is completely submerged in the interior of the positioning groove 3, the spring 903 rebounds, pushing the limiting block 902 into the interior of the limiting groove 909, which can realize the quick installation of the connection port 2. When it is necessary to disassemble the connection port 2, pull the pull rod 904, and then rotate the rotating plate 907 so that the first slot 906 is inserted into the interior of the second slot 908, and then pull out the connection port 2, which can realize the quick disassembly of the connection port 2.

[0034] Specifically, the sealing ring 8 is a rubber ring, and three identical sealing rings 8 are provided, with the three sealing rings 8 distributed at equal intervals. The advantage is that, due to the good sealing performance of the rubber ring, the design of the sealing ring 8 prevents humid air from entering the interior of the busbar trunking body 1 in a humid environment, thus avoiding leakage and damage to the copper busbar 13. The sealing performance is high, and the design of three sealing rings 8 further improves the overall sealing performance.

[0035] Example 2:

[0036] like Figure 2-7 As shown, as an improvement on the previous embodiment, to further facilitate heat dissipation of the copper busbar 13, specifically, the guide block 14 and the guide groove 15 are plug-in installed. The cross-section of the guide block 14 has a "T" shape, and the flame-retardant partition plate 12 is made of magnesium plate. The advantage is that workers can quickly install the flame-retardant partition plate 12 by inserting the guide block 14 into the guide groove 15. The magnesium plate has good fire resistance, which can effectively prevent the spread of fire and delay its propagation.

[0037] Specifically, the heat-conducting plate 18 and the mounting slot 16 are connected by a plug-in joint. The bolt 20 extends through the threaded hole 19 to the inside of the threaded hole 17. The threaded hole 19 and the threaded hole 17 have the same diameter. The advantage is that the worker can quickly install the heat-conducting plate 18 by inserting it into the mounting slot 16 and then extending the bolt 20 through the threaded hole 19 to the inside of the threaded hole 17. After long-term use, it is easy to clean and replace.

[0038] Specifically, multiple identical heat dissipation fins 21 are provided, and these multiple heat dissipation fins 21 are distributed at equal intervals. The advantage is that, through the design of the heat dissipation fins 21, cool air blown onto the surface of the heat dissipation fins 21 carries away the heat from the surface of the heat dissipation fins 21, which can achieve rapid heat dissipation of the copper busbar 13. The design of multiple heat dissipation fins 21 further improves the overall heat dissipation performance, avoids the copper busbar 13 from working in a high-temperature environment for a long time, and prevents damage, thus making it highly practical.

[0039] Working principle: During installation, the operator inserts positioning block 5 into positioning groove 3 and inserts block 6 into slot 4, enabling rapid positioning of connection port 2. During rapid positioning of connection port 2, when limit block 902 contacts positioning block 5, spring 903 contracts, and limit block 902 moves into movable groove 901. When positioning block 5 is completely submerged in positioning groove 3, spring 903 rebounds, pushing limit block 902 into limit groove 909, enabling rapid installation of connection port 2. When connection port 2 needs to be disassembled, pull rod 904 is pulled, and then rotating plate 907 is rotated, causing slot 1 906 to engage with slot 2 908, and then connection port 2 is pulled out, enabling rapid disassembly of connection port 2. Subsequently, the operator inserts guide block 14 into guide groove 15, enabling rapid installation of flame-retardant partition plate 12. Magnesium board has good fire resistance and can... To effectively prevent the fire from spreading and slow its propagation, the workers then inserted the heat-conducting plate 18 into the installation slot 16 and extended the bolt 20 through the threaded hole 19 to the threaded hole 17, enabling the rapid installation of the heat-conducting plate 18. After prolonged use, it is easy to clean and replace. During use, the design of the heat dissipation fins 21 allows cold air to be blown onto the surface of the heat dissipation fins 21, carrying away the heat from the surface of the heat dissipation fins 21, thus achieving rapid heat dissipation for the copper busbar 13. The design of multiple heat dissipation fins 21 further improves the overall heat dissipation performance, preventing the copper busbar 13 from working in a high-temperature environment for a long time, which would lead to damage. It has high practicality. Because the rubber ring has good sealing performance, the design of the sealing ring 8 prevents humid air from entering the interior of the busbar trunking body 1 in a humid environment, which would cause leakage and damage to the copper busbar 13. The sealing performance is high, and the design of three sealing rings 8 further improves the overall sealing performance.
