The cabinet comprises a main cabinet body 1, a drawer cabinet 2, a stand column 3, an outer sliding groove 4, an inner sliding strip 5, a front roller 6, a rear roller 7, a middle roller 8, a fixed wheel 9, a limiting wheel 10 and a guide wheel 11.

Detailed Description

The present invention will be further explained with reference to the following examples and the accompanying drawings.

In an embodiment, as shown in fig. 1 to 4, a draw-out switch cabinet includes a main cabinet body 1 and a plurality of drawer cabinets 2, wherein a vertical column 3 is disposed in the main cabinet body 1, a horizontal outer chute 4 is disposed on the vertical column 3, inner sliding strips 5 are disposed on two sides of each drawer cabinet 2 corresponding to the outer chute 4, a front roller 6, a rear roller 7 and at least one middle roller 8 are disposed on each inner sliding strip 5, and the front roller 6, the rear roller 7 and the middle roller 8 are in rolling contact with a lower supporting surface of the outer chute 4. The outer sliding groove 4 and the inner sliding strip 5 of the embodiment are jointly supported by the front roller 6, the rear roller 7 and the middle roller 8, and are in rolling contact with each other, so that the supporting stability and the sliding smoothness of the sliding are ensured, the drawer cabinet 2 is stably and reliably pushed and pulled for multiple times, and the installation, debugging and maintenance are facilitated.

In the embodiment, as shown in fig. 4, the inner slide bar 5 is further provided with a non-rotatable fixed wheel 9, and the fixed wheel 9 is arranged close to the front roller 6 and is in sliding contact with the lower supporting surface of the outer slide groove 4. The fixed wheel 9 of this embodiment is firstly it plays reliable supporting role, secondly plays a role in the condition that other gyro wheels especially preceding gyro wheel 6 became invalid, avoids drawer cabinet 2 push-and-pull to be unsmooth or card extremely.

In the embodiment, as shown in fig. 4, a limiting wheel 10 is arranged at the front end of the inner slide bar 5, and the limiting wheel 10 is in rolling contact with the upper supporting surface of the outer slide groove 4. The limiting wheels are mainly used for enabling the drawer cabinet 2 to be stably placed in the outer sliding groove 4 and avoiding shaking.

In an embodiment, as shown in fig. 4, the front roller 6 is located more forward relative to the limiting wheel 10. The structure facilitates pushing in at the initial stage.

In the embodiment, as shown in fig. 3, the outward end of the outer chute 4 is provided with a guide wheel 11, and the guide wheel is in rolling contact with the lower support surface of the inner slide bar 5. The structure can avoid the collision between the drawer cabinet 2 and the outer sliding groove 4, and also can play a role in auxiliary rolling support.

In the embodiment shown in fig. 1 and 2, the vertical position of the outer sliding chute 4 is adjustable, and this arrangement is mainly for facilitating the placement of the drawer cabinets 2 with different sizes, for example, as shown in fig. 1, the height of the bottom drawer cabinet 2 is significantly greater than that of the upper drawer cabinet 2. Specifically, the upright post 3 is provided with a plurality of mounting holes in the vertical direction, and the two ends of the outer chute 4 are fixed with special mounting plates which are fixed in the mounting holes through bolts. For convenient assembly, the mounting hole of the outer chute 4 is a long hole in the horizontal direction.

It is obvious that the above embodiments of the present invention are only examples for illustrating the present invention, and are not intended to limit the embodiments of the present invention. Obvious changes or variations coming within the spirit of the invention are intended to be covered by the scope of the invention.
