Description

Draw-out type low-voltage switch cabinet

Technical Field

The utility model relates to the technical field of low-voltage switch cabinets, in particular to a draw-out type low-voltage switch cabinet.

Background

The switch cabinet is an electrical device, the external line of the switch cabinet firstly enters the main control switch in the cabinet, then enters the sub-control switch, and each shunt is arranged according to the requirement. Such as meters, self-control, motor magnetic switches, various ac contactors, etc. The main function of the switch cabinet is to open and close, control and protect electric equipment in the process of generating, transmitting, distributing and converting electric energy of the electric power system. The components in the switch cabinet mainly comprise a breaker, a disconnecting switch, a load switch, an operating mechanism, a transformer, various protection devices and the like. According to different voltage levels, the power supply can be divided into a high-voltage switch cabinet, a low-voltage switch cabinet and the like. The method is mainly suitable for various different occasions such as power plants, transformer substations, petrochemical industry, metallurgical steel rolling, light industry textile, factories and mining enterprises, residential communities, high-rise buildings and the like.

The existing switch cabinets are multiple, one of the switch cabinets is a draw-out low-voltage switch cabinet, but when the existing draw-out low-voltage switch cabinet draws out a drawer in the draw-out low-voltage switch cabinet, the drawer is easy to draw out all the drawer when the drawer is drawn out due to the fact that the electronic components in the drawer are numerous and heavy, and the drawer falls down to cause damage to the electronic components.

Disclosure of Invention

To the above-mentioned not enough of prior art, the technical problem that this patent application was to solve is how to provide a draw-out type low-voltage switchgear that has self-locking structure, and with low costs, the operation of being convenient for.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the utility model provides a pull-out type low tension switchgear, includes cubical switchboard body and a plurality of drawer, the both ends of cubical switchboard body are just to drawer fixed mounting has the bracket, the bracket is the L type, a plurality of gyro wheels are installed in the both ends rotation of drawer, gyro wheel and bracket rolling fit, two handles are fixed mounting in the outside of drawer, still be provided with the auto-lock structure between drawer and the cubical switchboard body.

Therefore, when the drawer is pulled outwards, the handle is pulled outwards due to the existence of the self-locking structure, the drawer moves outwards to the self-locking position of the self-locking structure to stop, and the drawer is prevented from being separated from the switch cabinet body. When the drawer needs to be disassembled, the self-locking structure is unlocked, the handle is pulled outwards, and the drawer is taken out. And the roller wheels are arranged, so that the drawer can be pulled conveniently.

The self-locking structure comprises a self-locking rod, one end of the self-locking rod penetrates through a drawer to be externally fixed with a handle, the drawer is just opposite to the self-locking rod and is fixed with a rubber ring, the other end of the self-locking rod is fixed with a locking block, a support is fixed on the drawer, the self-locking rod is connected with the support through a bearing, one end of the locking block is arc-shaped, the switch cabinet body is just opposite to a self-locking chute, the outer end of the self-locking chute is closed, the cross section of the self-locking chute is semicircular, and the locking block is in sliding fit with the self-locking chute.

Wherein, the self-locking structure is provided with two and is respectively arranged at two sides of the drawer.

Wherein, the drawer is provided with a plurality of mounting holes in a distributed way.

Wherein, the bracket is welded with the hanging cabinet body.

In conclusion, the utility model has the advantages of self-locking structure, low cost and convenient operation.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the azimuth or positional relationship indicated by the azimuth words such as "upper, lower" and "top, bottom", etc. are generally based on the azimuth or positional relationship shown in the drawings, and are merely for convenience of description and simplification of the description, and these azimuth words do not indicate or imply that the apparatus or element to be referred to must have a specific azimuth or be constructed and operated in a specific azimuth, without limiting the scope of protection of the present utility model; the orientation word "inner and outer" refers to inner and outer relative to the contour of the respective component itself.

As shown in fig. 1-5, the draw-out type low-voltage switch cabinet comprises a switch cabinet body 1 and a plurality of drawers 2, wherein brackets 3 are fixedly arranged at the two ends of the switch cabinet body opposite to the drawers, the brackets are L-shaped, a plurality of rollers 4 are rotatably arranged at the two ends of each drawer and are in rolling fit with the brackets, two handles 5 are fixedly arranged at the outer sides of the drawers, and a self-locking structure is further arranged between each drawer and the switch cabinet body.

In this embodiment, the auto-lock structure includes from locking lever 6, the one end of from locking lever passes the drawer and outwards is fixed with handle 7, and the drawer just is fixed with the rubber circle to the auto-lock lever, through the rubber circle for from the locking lever can fix at current state, needs manual rotation handle just can drive the auto-lock lever and rotate, the other end of from the locking lever is fixed with locking piece 8, be fixed with the support on the drawer, from locking lever and support pass through the bearing and be connected, the one end of locking piece is the arc, the cubical switchboard body just is provided with auto-lock spout 9, and the outer end of auto-lock spout is sealed, the cross-section of auto-lock spout is semi-circular, locking piece and auto-lock spout sliding fit. Under the locking state, the handle is downwards arranged, the locking block is positioned in the self-locking sliding groove, and the drawer is pulled outwards until the locking block is abutted with the self-locking sliding groove. When the drawer needs to be pulled out, the handle is rotated to be in a horizontal state, the locking block is rotated out of the self-locking chute, and the drawer is pulled outwards.
