Description

Traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Plug-in bus ducts have emerged as a new type of distribution conductor. Compared with traditional cables, they fully demonstrate their superiority in high-current transmission. At the same time, due to the use of new technologies and processes, the contact resistance and temperature rise of the connection points at both ends of the bus duct and the plug-in points of the branch ports are greatly reduced. High-quality insulating materials are used in the bus duct, thereby improving the safety and reliability of the bus duct and making the entire system more perfect.

[0028] like Figures 1 to 7As shown, the present invention provides a bus duct with a folding function, comprising a first bus duct 1, a second bus duct 2, a left-handed screw rod 3 and a right-handed screw rod 4, a left-handed screw rod 3 and a right-handed screw rod 4 are arranged on one side edge of the first bus duct 1 and the second bus duct 2, a rotating mechanism 7 is arranged on the opposite ends of the left-handed screw rod 3 and the right-handed screw rod 4, a moving mechanism 5 is arranged at the connection positions of the left-handed screw rod 3 and the right-handed screw rod 4 and the corresponding first bus duct 1 and the second bus duct 2, a side seat 8 is arranged on the other side edge of the first bus duct 1 and the second bus duct 2, a vertical seat 16 is arranged on the first bus duct 1, and the vertical seat 16 A pushing mechanism 12 is slidably connected at the top, and the output end of the pushing mechanism 12 is overlapped with the pulling mechanism 14. The output end of the pulling mechanism 14 is connected to the limiting mechanism 15. The output end of the limiting mechanism 15 corresponds to the limiting rod 10 on the second bus duct 2. The limiting rod 10 is provided with a bayonet 11, and the bayonet 11 is connected to the output end of the limiting mechanism 15. When the bus duct as a whole needs to be folded, the clamping head 153 is first pulled out of the bayonet 11, and then the left-handed screw rod 3 and the right-handed screw rod 4 are rotated. When the left-handed screw rod 3 and the right-handed screw rod 4 are rotated, the threaded seat 503 can move along the corresponding left-handed screw rod 3 and the right-handed screw rod 4.

[0029] The first bus duct 1 and the second bus duct 2 can be separated, and the limit rod 10 and the slide rod 9 on the first bus duct 1 and the second bus duct 2 can gradually separate from the corresponding side seat 8.

The first clamping seat 705 and the second clamping seat 706 on the left-hand screw rod 3 and the right-hand screw rod 4 can be rotated to cooperate with the rotation of the first bus duct 1 and the second bus duct 2. The first clamping seat 705 and the second clamping seat 706 will not separate from each other during the rotation process, so that the first bus duct 1 and the second bus duct 2 will not be separated from each other after folding, thereby facilitating later recovery.

[0030] A sliding bar 9 is provided on the side seat 8 of the first bus duct 1, and the sliding bar 9 is located below the side seat 8.

When the vertical rod 152 is pushed upward, the connected clamping head 153 can be driven to move upward, and the clamping head 153 can be clamped into the clamping mouth 11 of the limiting rod 10. When the clamping head 153 is inserted into the clamping mouth 11, the limiting rod 10 will not be pulled horizontally, and the first bus duct 1 and the second bus duct 2 can be stably connected without folding and rotating, thereby ensuring that the first bus duct 1 and the second bus duct 2 will not rotate during laying and affect use.

When the left-handed screw rods 3 and right-handed screw rods 4 rotate, the threaded seats 503 will move along the corresponding left-handed screw rods 3 and right-handed screw rods 4, and the first bus duct 1 and the second bus duct 2 will approach each other or separate from each other. A side seat 8 is set at the other end of the first bus duct 1 and the second bus duct 2. A sliding rod 9 is provided on the side seat 8 of the first bus duct 1 to be inserted into the second bus duct 2. The second bus duct The limiting rod 10 on 2 is inserted into the first bus duct 1, and the left-hand screw rod 3 and the right-hand screw rod 4 can separate the first bus duct 1 and the second bus duct 2 from each other when they are rotated. When the limiting rod 10 and the sliding rod 9 are separated from the corresponding side seats 8, the first bus duct 1 and the second bus duct 2 can be rotated and folded. By installing the first clamping seat 705 and the second clamping seat 706 on the rotating seat 6 of the left-hand screw rod 3 and the right-hand screw rod 4, the first clamping seat 705 and the second clamping seat 706 can be rotated through the connecting head 703 and the connecting seat 704 without falling off.
