Description

An integrated power distribution drawer cabinet

Technical Field

The present invention relates to the technical field of power distribution drawer cabinets, and in particular to an integrated power distribution drawer cabinet.

Background Art

The design concept of integrated drawer cabinets is to highly integrate various electrical components, such as molded case circuit breakers, mutual inductors, control and protection devices, etc. in a compact space to reduce the overall size and improve space utilization. This design is particularly suitable for power distribution systems, such as commercial buildings, industrial facilities or data centers, where space limitations are a key factor. Usually, the handle of the power distribution drawer cabinet is designed to have the functions of controlling the switch and the drawer operation. Among them, by rotating the handle to a specific position, the switch can be turned on or off. Secondly, when the handle is rotated to a specific position, it can also allow the drawer to be pulled out or pushed in from the cabinet.

However, long-term use usually causes the handle itself to age and become very fragile, so that when too much force is applied when opening or closing the drawer, the handle cannot withstand the force and breaks. When the handle of the power distribution drawer cabinet is damaged, it is necessary to pry the drawer open violently. Prying the drawer open violently will cause the track, pulley or other moving parts of the drawer cabinet to be subjected to excessive force, which will cause deformation, breakage or failure. Finally, when the parts of the drawer cabinet are replaced, this will affect the working efficiency of the power distribution drawer cabinet or increase maintenance costs.

The drawer 2 is provided with a telescopic mechanism inside to prevent the drawer 2 from falling out of the drawer cavity after being inserted into the slot; the installation cavity 221 is provided on the drawer 2 and the baffle 3, and the interior of the installation cavity 221 is fixedly connected with a partition plate 222 that limits the spiral connection block 223 from moving toward the first bevel gear 225, and the partition plate 222 is movably connected to the spiral rod 224. The installation cavity 221 is provided with a switch mechanism that drives the telescopic mechanism to fall out of the slot, and the backup switch mechanism also ensures that no accidental injury or damage to items will occur during use, which is safer and more reliable than violent operation. At the same time, the user no longer needs to rely on the switch handle 31, and can easily use the switch mechanism to complete the required operation.

Further, the switch mechanism includes a second bevel gear 35, and a spiral rod 224 is rotatably connected inside the mounting cavity 221. The top fixed sleeve of the spiral rod 224 is provided with a first bevel gear 225 meshingly connected with the second bevel gear 35. The second bevel gear 35 and the first bevel gear 225 are bevel gears, and the bevel gear is a special type of gear whose gear tooth surface is not parallel to the axis but arranged in a cone. This design allows the bevel gear to transfer power from one axis to another when working, and their axes can intersect or be parallel but not colinear. The bottom spiral sleeve of the spiral rod 224 is provided with a spiral connection block 223, and a V-shaped connection frame 226 is fixedly connected to the spiral connection block 223, and an elliptical bracket 227 is fixedly connected to the end of the V-shaped connection frame 226 away from the spiral rod 223.
