[0002] The bus duct is a closed metal device composed of copper and aluminum busbar columns. Currently, more and more engineering projects have begun to use bus ducts instead of wires and cables for power transmission. However, in the connection process of the existing bus duct structure, connecting components are needed to connect the two bus ducts. When the connecting components in the existing bus duct are used, in order to ensure the conductivity during later use, the copper conductors in the bus duct need to be connected and clamped first. At the same time, in order to ensure the fire-resistant and waterproof effect of the bus duct, the connecting parts of the two bus ducts need to be sealed. However, since the two tasks need to be carried out step by step, it indirectly leads to the trouble of connecting the bus duct. Summary of the invention

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Please refer to Figures 1 to 6 :

[0031] Embodiment 1:

[0032] The utility model proposes a fire-resistant and waterproof bus duct structure, comprising: a sealed shell 1, a sealed connector 3 and a sealing plate 4, wherein a conductive copper sheet 2 is installed inside the sealed shell 1, and two ends of the conductive copper sheet 2 extend and protrude from the two ends of the sealed shell 1; the U-shaped sealed connector 3 is located at the butt joint of the two sealed shells 1; the sealing plate 4 is located above the sealed connector 3; a conductive connector 301 is installed inside the sealed connector 3; the conductive connector 301 is staggeredly connected with the conductive copper sheet 2; a slot 302 is opened at the center of the top of the sealed connector 3; a pressure plate 401 is fixedly installed at the center of the bottom of the sealing plate 4; when the sealing plate 4 is butt jointed with the sealed connector 3, the pressure plate 401 will be inserted into the inside of the slot 302.

[0033] The sealing plate 4 is manually docked with the sealing connector 3. During the docking process, the pressure plate 401 will be inserted into the interior of the slot 302. After the insertion, the pressure plate 401 will push the inclined surface of the pressure piece 3013, so that the pressure piece 3013 begins to move inward under the influence of the pushing force and clamps the conductive connector 301 and the conductive copper sheet 2 to ensure the tightness of the connection between the conductive connector 301 and the conductive copper sheet 2.

[0034] Embodiment 2, based on embodiment 1,

[0035] The left and right sides of the top of the sealing connector 3 are provided with docking grooves 303; the front and rear sides of the sealing shell 1 are also provided with connecting grooves 304; the bottom positions of the front and rear sides of the sealing connector 3 are also provided with contraction grooves 305; the contraction grooves 305 are connected with the docking grooves 303; a positioning block 306 is slidably installed inside the contraction groove 305; the outer end of the positioning block 306 is an inclined structure; a transmission groove 307 is provided on the outer wall of the positioning block 306; the transmission groove 307 is an inclined structure; one end of a spring A308 is embedded and installed at the inner end of the positioning block 306; the other end of the spring A308 is embedded and installed on the inner wall of the contraction groove 305; a synchronous frame 309 is slidably installed at the bottom of the sealing connector 3; a transmission column 3010 is also fixedly installed at the inner end of the synchronous frame 309; the transmission column 3010 is also slidably installed inside the transmission groove 307; the transmission column 3010 is a cylindrical structure.

[0036] When the sealing plate 4 is docked with the sealing connector 3, the docking plate 402 will also be inserted into the docking groove 303. During the insertion process, the docking plate 402 will push the inclined surface of the positioning block 306, so that the positioning block 306 is forced to shrink toward the inside of the shrinkage groove 305 first. When the docking plate 402 is fully inserted into the docking groove 303, the positioning block 306 will be inserted into the docking slot 403 under the action of the spring A308, thereby realizing a firm connection between the sealing plate 4 and the sealing connector 3.

[0037] Embodiment 3, based on embodiment 1,

[0038] A clamping guide plate 3011 is slidably installed inside the connecting groove 304; the clamping guide plate 3011 is an L-shaped structure; one end of a spring B3012 is embedded and installed on the inner side of the clamping guide plate 3011; the other end of the spring B3012 is embedded and installed on the outer wall of the sealing connector 3; a pressure piece 3013 is fixedly installed on the inner end of the clamping guide plate 3011; the top of the pressure piece 3013 is an inclined structure; after the pressure plate 401 is inserted into the interior of the slot 302, the pressure plate 401 will push the inclined surface of the pressure piece 3013; docking plates 402 are fixedly installed on the left and right sides of the bottom of the sealing plate 4; when the sealing plate 4 is docked with the sealing connector 3, the docking plate 402 will be inserted into the interior of the docking groove 303; a docking card slot 403 is provided on the inner side of the docking plate 402.

[0039] When the sealing plate 4 needs to be removed from the sealing connector 3, it is only necessary to pull down the synchronous frame 309 to make the synchronous frame 309 and the four transmission columns 3010 descend. During the descending process, the transmission column 3010 will use the inclined structure of the transmission groove 307 to move the four positioning blocks 306 inward, so that the four positioning blocks 306 slide out from the inside of the docking slot 403, thereby canceling the fixed relationship between the sealing plate 4 and the sealing connector 3, making it easy to remove the sealing structure from the sealing shell 1.

[0040] The working principle of this embodiment:

[0041] First, the sealing connector 3 is installed at the connection position of the two sealing shells 1, and then the sealing plate 4 is manually docked with the sealing connector 3. During the docking process, the pressure plate 401 will be inserted into the inside of the slot 302, and after the insertion, the pressure plate 401 will push the inclined surface of the pressure piece 3013, so that the pressure piece 3013 begins to move inward under the influence of the pushing force and clamps the conductive connector 301 and the conductive copper sheet 2 to ensure the connection tightness of the conductive connector 301 and the conductive copper sheet 2. When the sealing plate 4 is docked with the sealing connector 3, the docking plate 402 will also be inserted into the interior of the docking groove 303. During the insertion process, the docking plate 402 will push the inclined surface of the positioning block 306, so that the positioning block 306 is forced to shrink toward the inside of the shrinkage groove 305 first. When the docking plate 402 is fully inserted into the interior of the docking groove 303, the positioning block 306 will be inserted into the interior of the docking card slot 403 under the action of the spring A308, thereby achieving a firm connection between the sealing plate 4 and the sealing connector 3, and utilizing the sealing plate 4 and the sealing connector 3 to ensure the fire resistance and fireproof effect of the bus duct structure.
