Technical Field

[0001] The utility model relates to the technical field of busbar plug-in boxes, in particular to a busbar plug-in box locking device. Background Art

[0002] The busbar plug-in box can only take power by inserting the pins into any busbar position. Most of the existing busbar plug-in boxes are installed and fixed with screws and locking feet. For example, in the patent number "CN210838868U" and the patent name "A busbar plug-in box locking device", the bottom of the busbar plug-in box 1 is installed on the profile through a connecting plate. The connecting plate is in an inverted "L" shape, and the short side is riveted to the bottom or side of the busbar plug-in box, and the long side is installed on the profile. Two screw holes are provided on the long side of the connecting plate. The side of the busbar plug-in box is also fixedly connected to the profile through a locking foot. At the installation position of the connector of the profile, a mold is used to punch a hole so that a semicircular punching hole is formed at one end of the protruding part of the profile close to the recessed part for installing the second screw. The connector is a rectangular cast iron with a screw hole on it for installing the first The height of the connecting piece is less than the height of the concave part of the side of the profile, so that the connecting piece can be placed in the concave part of the side of the profile. When in use, the connecting piece is placed in the concave part of the profile so that the screw hole on the connecting piece is aligned with the screw hole on the connecting plate. The second screw is installed through the semicircular punching hole on the profile to fix the connecting piece in the profile. The first screw is installed at the overlapped position of the screw hole of the connecting plate and the screw hole of the connecting piece to fix the connecting plate and the connecting piece, thereby making the busbar plug-in box fixedly connected to the profile. When the first screw and the second screw are connected, a gasket is used to make the connection tighter. A sawtooth is provided on one side of the connecting piece close to the inner side of the protruding part of the profile to enhance the fastening force between the connecting piece and the profile to prevent the connecting piece from falling off due to vibration or shaking. However, the above structure still has the following problems in actual use:

[0003] The above structure uses the first screw and the second screw in conjunction with the locking foot to fix the plug-in box. However, although this method achieves the fixing effect, the busbar plug-in box is generally hoisted at a high place, and the multi-point bolt connection method causes the busbar plug-in box to be cumbersome to disassemble and assemble, affecting the workers' construction and maintenance efficiency of the busbar plug-in box.

[0004] Therefore, we proposed a busbar junction box locking device that can solve the above problems well. Utility Model Content
