Description
Technical Field
The invention relates to the technical field of distribution boxes, in particular to a draw-out type switch cabinet.
Background
The draw-out type switch cabinet is a device commonly used in an electrical power distribution system and comprises a frame and a drawer, wherein the drawer is connected to the frame in a sliding manner through a sliding rail, so that the convenience of the use of the switch cabinet is improved.
The sliding rail not only needs to bear the weight of the drawer, but also ensures the stability and smoothness of the drawer in the push-pull process. Therefore, the optimization design of the sliding rail is a key for improving the performance of the draw-out type switch cabinet. The slide rail comprises an outer guide rail, an inner guide rail and a ball retainer, wherein the outer guide rail and the inner guide rail are respectively fixedly connected to the frame and the drawer, a plurality of balls are arranged on the ball retainer, the top surfaces and the bottom surfaces of the balls protrude out of the ball retainer, and the balls are abutted with the outer guide rail and the inner guide rail and rotate so that the outer guide rail and the inner guide rail can slide relatively.
According to the related technology, after the sliding rail is used for a period of time, the balls are not smooth to operate, push-pull of the drawer is hindered, the outer guide rail and the inner guide rail are easy to rust after the sliding rail is used for a period of time, smoothness and stability of the sliding rail are affected, lubricating oil needs to be added on the sliding rail, but the process of adding the lubricating oil is complicated, a worker is required to draw out the drawer, and the lubricating oil is added on the inner frame and the ball retainer, so that the working efficiency is low.
Disclosure of Invention
In view of the above, the invention provides a draw-out type switch cabinet, which aims to solve the technical problem that lubricating oil is difficult to be added to a sliding rail on the switch cabinet in the prior art.
In order to solve the technical problems, the invention provides a pull-out type switch cabinet, which adopts the following technical scheme: the draw-out type switch cabinet comprises a plurality of drawers and a frame for accommodating the drawers, wherein a ball retainer is arranged between an outer guide rail fixedly connected with the frame and an inner guide rail fixedly connected with the drawers, one end of the ball retainer is connected with a connecting block, one side of the drawers is connected with a connecting plate in a sliding manner, a limiting piece is arranged between the connecting plate and the connecting block, and the limiting piece enables the connecting block and the connecting plate to synchronously move; and the supporting piece is used for supporting the drawer when the ball retainer is separated from the inner guide rail and the outer guide rail.
Through adopting above-mentioned technical scheme, locating part makes connecting block and connecting plate synchronous motion, and push-and-pull connecting plate can drive connecting block and ball holder and remove, is convenient for take out the ball holder alone to add lubricating oil to the ball holder, push back the ball holder between outer guide rail and the interior guide rail after adding, lubricating oil on the ball holder can lubricate interior guide rail and outer guide rail, thereby hoisting device's smooth degree reduces the rusty condition emergence of device. The ball retainer is independently pushed and pulled, so that the workload of workers when lubricating oil is added to the device is reduced, the drawers are not required to be pushed and pulled, the sight obstruction and operation obstruction of the drawers to the workers when the lubricating oil is added are reduced, and the operation is convenient. The problem that lubricating oil is difficult to add to the sliding rail in the past is solved.
Optionally, the locating part includes the butt board, set up logical groove on the connecting block, butt board one end connect in the connecting plate, butt board other end butt in logical inslot wall.
Through adopting above-mentioned technical scheme, set up the board of keeping out, simple structure can drive connecting block and ball holder and move together when making the push-and-pull connecting plate. Compared with the mode of directly adopting connecting plate and connecting block fixed connection, make connecting plate and connecting block synchronous movement's mode through the butt plate, device flexibility and adjustability are higher.
Optionally, rotate on the connecting plate and be connected with the handle, handle one end pass the drawer and fixed connection in keep out board one end, the logical groove runs through in the vertical direction the connecting block, keep out the board with the handle synchronous rotation, keep out the board butt in the drawer inner wall, the connecting plate is kept away from one side fixedly connected with baffle of ball holder, the baffle butt in the drawer.
Through adopting above-mentioned technical scheme, set up the handle, be convenient for exert oneself to the connecting plate. The handle and the connecting plate rotate, and the retaining plate and the handle synchronously rotate. When the ball retainer is required to be pushed and pulled independently, the handle is rotated, the retaining plate is abutted with the inner wall of the through groove, and the connecting plate and the ball retainer can be driven to move by pushing and pulling the handle, so that the ball retainer is convenient to use. When the drawer needs to be pushed and pulled, the handle is rotated to enable the abutting plate to abut against the inner wall of the drawer, the abutting plate is matched with the baffle plate, the handle and the drawer synchronously move, and the drawer can be pushed and pulled by pushing and pulling the handle.
