Description

Technical Field

[0001] The utility model belongs to the technical field of bus ducts, and particularly relates to a copper-aluminum composite bus duct. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbar columns, which is used to distribute large power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk projects. The characteristics of bus duct are series matching, commercial production, small size, large capacity, short design and construction period, easy installation and disassembly, no combustion, safety and reliability, and long service life.

[0003] After searching, in the prior art, China Patent Publication No.: CN217486121U, Authorization Date: 2022-09-23, discloses a copper-aluminum composite busbar duct, including a copper-aluminum composite bar and an insulating spacer. Guard plates are provided on both sides of the copper-aluminum composite bar, and a fixing bolt is installed at the front end of the guard plate. A groove is provided in the middle of the guard plate. The rear end of the guard plate is connected to the insulating spacer. The front end of the insulating spacer is provided with a bolt hole, and the rear end of the bolt hole is provided with a screw sleeve.

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0024] The present invention provides a copper-aluminum composite bus duct, comprising two bus duct cover plates 1, for example, Figure 1-Figure 4 shown.

[0025] Two grooves 2 are provided on one side of the bus duct cover plate 1, and two bus duct side plates 3 are slidably connected to the opposite sides of the two bus duct cover plates 1. The bus duct side plates 3 are located in the inner cavity of the groove 2. A copper-aluminum composite bar body 5 is provided on the opposite side of the two bus duct cover plates 1. The top and bottom of the copper-aluminum composite bar body 5 are slidably connected with a recessed block 4. One side of the recessed block 4 is fixedly connected to the bus duct cover plate 1. Two shells 6 are fixedly connected to one side of the bus duct cover plate 1. The bottom of the inner cavity of the shell 6 is rotatably connected to a long rod 7. The inner cavity of the shell 6 is provided with a positioning mechanism 8, and the interior of the long rod 7 is provided with a locking mechanism 9.

[0026] The positioning mechanism 8 includes a first gear 81 sleeved on the surface of the long rod 7. Figure 1-Figure 4 shown.

[0027] Guide rods 82 are fixedly connected to both sides of the inner cavity of the shell 6, and a tooth plate 83 is sleeved on the surface of the guide rod 82. A first spring 84 is provided in the inner cavity of the tooth plate 83. The two ends of the first spring 84 are respectively fixedly connected to the guide rod 82 and the tooth plate 83. A positioning block 85 is fixedly connected to one side of the tooth plate 83. One side of the positioning block 85 passes through the inner cavity of the groove 2. Positioning grooves 86 are provided at the top and bottom of one side of the bus duct side plate 3.

[0028] Specifically, by setting the positioning mechanism 8, a stable and reliable connection can be established between the bus duct cover plate 1 and the bus duct side plate 3. When external vibration or impact occurs, the bus duct cover plate 1 and the bus duct side plate 3 are not easily separated, thereby ensuring the overall stability and safety of the bus duct cover plate 1 and the bus duct side plate 3.

[0029] The locking mechanism 9 includes a gear ring 91 fixedly connected to the top of the housing 6. Figure 1-Figure 4 shown.

[0030] The inner cavity of the gear ring 91 is provided with a second gear 92, and the inner cavity of the long rod 7 is provided with a movable block 93. The top of the movable block 93 is fixedly connected to a short rod 94, one end of the short rod 94 passes through the outside of the long rod 7 and is fixedly connected to the second gear 92. The surface of the short rod 94 is sleeved with a second spring 95, and the two ends of the second spring 95 are fixedly connected to the long rod 7 and the movable block 93 respectively.

[0031] Specifically, when the locking mechanism 9 is in the locked state, it can effectively prevent the bus duct cover plate 1 and the bus duct side plate 3 from accidentally separating, thereby ensuring the integrity and safety of the device. At the same time, by rotating the second gear 92, the opening and closing of the positioning mechanism 8 can be conveniently controlled, avoiding safety hazards caused by misoperation or external interference.

[0032] The top of the second gear 92 is fixedly connected to a handle 10, and the surface of the handle 10 is provided with anti-slip grooves, such as Figure 1-Figure 4 shown.

[0033] A slide groove 11 is provided on the front and rear sides of the inner cavity of the shell 6. A slider 12 is slidably connected to the inner cavity of the slide groove 11. One side of the slider 12 is fixedly connected to the tooth plate 83. A telescopic structure is formed between the first spring 84 and the tooth plate 83, and the maximum movement distance of the tooth plate 83 is equal to the deformation of the first spring 84. The number of the copper-aluminum composite bar body 5 is five, and the copper-aluminum composite bar body 5 is used in conjunction with the concave block 4. Both sides of the busbar cover 1 are provided with inclined surfaces, and the inclined surface is smooth.

[0034] Specifically, by using the handle 10 and the anti-slip groove in combination, the friction between the user's palm and the handle 10 is increased, thereby facilitating the user to move the second gear 92 out of the inner cavity of the second gear 92. By using the slide groove 11 and the slider 12 in combination, the tooth plate 83 is limited, thereby improving the stability of the tooth plate 83 during movement. By setting the first spring 84, the positioning block 85 can be firmly placed in the inner cavity of the positioning groove 86, thereby making it difficult for the bus duct cover plate 1 and the bus duct side plate 3 to separate.

[0035] The copper-aluminum composite busbar trunking proposed in the embodiment of the present invention has the following working principles:

[0036] When the device is in use, the user moves the handle 10 upward, the handle 10 drives the second gear 92 to move upward, the second gear 92 drives the short rod 94 to move, the short rod 94 drives the movable block 93 to move, and the movable block 93 drives the second spring 95 to be compressed when it moves. When the second gear 92 disengages from the inner cavity of the gear ring 91, the handle 10 is turned, and the handle 10 drives the second gear 92 to rotate. When the second gear 92 rotates, it drives the long rod 7 to rotate through the movable block 93, and the long rod 7 drives the first gear 81 to rotate. The first gear 81 drives the two tooth plates 83 to slide on the surface of the guide rod 82. When the tooth plate 83 moves, the first spring 84 is compressed when the tooth plate 83 moves, and the tooth plate 83 drives the positioning block 85 to move out of the inner cavity of the positioning groove 86, so that the positioning block 85 gradually moves into the inner cavity of the shell 6. When the positioning block 85 is completely out of the inner cavity of the positioning groove 86, the fixation of the bus duct cover plate 1 and the bus duct side plate 3 can be released, which is convenient for the user to disassemble. The user releases the handle 10, and the rebound force of the second spring 95 makes the second gear 92 enter the inner cavity of the gear ring 91, so as to fix the position of the positioning block 85, so that the positioning block 85 is not easy to pop out of the inner cavity of the shell 6.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
