An object of the utility model is to overcome prior art's is not enough, provides a pull-out type cubical switchboard's interlocking device, can realize according to electric operating mechanism operating function combined floodgate and separating brake time, locking and separation requirement that the drawer can reach.

In order to achieve the above purpose, the utility model discloses a technical scheme is: the interlocking mechanism of the draw-out switch cabinet is applied to a drawer and locks a supporting plate to prevent the drawer from being drawn out in an electrified way.

Furthermore, holes matched with the interlocking pieces in size are formed in the drawer and the supporting plate, and the holes and the interlocking pieces are matched to limit the movement of the drawer on the supporting plate.

Furthermore, the drawer is provided with a first fixing part for connecting the elastic part and a second fixing part for installing the positioning shaft.

Further, the movement of the interlocking piece is blocked in the switching-on and switching-off movement process of the switch handle.

Further, the switch handle as described above is mounted on a molded case switch, which is located in the drawer.

Further, the elastic member as described above is a spring.

Furthermore, the switch handle is also connected with an electric operating mechanism to automatically switch on and off.

Compared with the prior art, the beneficial effects of the utility model are that: the device is convenient to operate, can effectively prevent misoperation of taking out the drawer due to electrification of a switch, and guarantees electrical safety.

Detailed Description

The following detailed description is provided to further explain the technical features and advantages of the present invention by referring to the accompanying drawings in combination with the embodiments.

As shown in fig. 1-3, the interlocking mechanism of a pull-out type cubical switchboard of the utility model, locking layer board 9 prevents to take out drawer 4 with electricity in being applied to drawer 4, including interlocking piece 3, 3 one end of interlocking piece receive the spacing of switch handle 2, the interlocking piece 3 other end links to each other with elastic component 6, interlocking piece 3 is rotatory around location axle 7 and makes between drawer 4 and the layer board 9 spacing locking or separation.

Furthermore, holes matched with the interlocking pieces 3 in size are formed in the drawer 4 and the supporting plate 9, and the holes are matched with the interlocking pieces 3 to limit the movement of the drawer 4 on the supporting plate 9. The drawer 4 is provided with a first fixing piece 5 for connecting the elastic piece 6 and a second fixing piece 8 for installing the positioning shaft 7. And the movement of the interlocking piece 3 is blocked in the switching-on and switching-off movement process of the switch handle 2. The switch handle 2 is arranged on the plastic shell switch 1, and the plastic shell switch 1 is positioned in the drawer 4. The elastic element 6 is a spring.

Furthermore, the switch handle 2 is also connected with an electric operating mechanism to automatically switch on and off.

As shown in fig. 2, an electric operating mechanism in the drawer 4 drives the switch handle 2 to a switching-on position, at this time, the drawer 4 is in a switching-on live working state, the switch handle 2 pulls the right side of the interlocking piece 3 at the switching-on position, so that the interlocking piece 3 rotates by the positioning shaft 7 and is screwed into holes in the drawer 4 and the supporting plate 9 to clamp the drawer 4 and cannot be drawn out, at this time, the spring is in a stretched stressed state, and the right side of the interlocking piece 3 is pressed by the switch handle 2.

As shown in fig. 3, the electric operating mechanism in the drawer 4 drives the switch handle 2 to the opening position, at this time, the drawer 4 is in the opening maintenance state, the switch handle 2 is in the opening position, the right side of the interlocking piece 3 is not pressed by the switch handle 2, the interlocking piece 3 rotates around the positioning shaft 7 and is screwed out of the holes in the drawer 4 and the supporting plate 9 under the pulling force of the spring, so that the drawer 4 is not clamped with the supporting plate 9, and at this time, the drawer 4 can be pulled out for maintenance.

In the device of the utility model, the interlocking piece 3 moves under the action of the switch handle 2 and the spring, and the execution action of blocking the locking drawer 4 and the supporting plate 9 and loosening the separation drawer 4 and the supporting plate 9 is achieved. The interlocking piece 3 realizes the locking and separation requirements which are met by the requirements of the drawer 4 corresponding to the opening and closing of the electric operating mechanism. The drawer 4, the spring, the positioning shaft 7 and other parts are all the prior art or materials, and the skilled person can directly purchase or order from the market according to the required product model and specification.

it will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "mounted on" another element, it can be directly mounted on the other element or intervening elements may also be present.
