Description

High safe type electricity behaviour drawer unit

Technical Field

The invention relates to the field of electrical equipment, in particular to a high-safety electrically-operated drawer unit.

Background

With the rapid development of low-voltage cabinet products in recent years and the increasing urgent need and eager hope of high-end users for the safety of electric appliances, the initial purpose of researching and manufacturing the high-safety low-voltage cabinet is to meet the development need of the era, and the strategic consideration of always putting people at first is carried out.

Most drawer units adopting a pull-out type at present are designed on the basis of a manual operation mode, and are not applicable to the requirement of error-proof interlocking in an electric operation mode. Because the electrically operated drawer is not provided with a handle and a matched interlocking mechanism, the electrically operated drawer is very unsafe, some users do not know the attention, and the electrically operated drawer can be directly pulled out when being electrified, so that the electrically operated drawer is very dangerous and has larger potential safety hazards. Due to the structural problem, the drawer electric operating loop is easy to operate in an electrified mode, mechanical locking is not available, and therefore switching-on and switching-off can only be operated through the electric loop, so that the situation that the electric operation is drawn out to a test position when in a switching-on state of a working position cannot be avoided, the drawer electric operating loop is drawn out under the switching-on condition, the electrified operation is not in accordance with a maintenance test rule, and the potential safety hazard that the operation is unsafe, the electric power loop is unstable in operation, and the fault or the personal accident of a low-voltage power distribution system is easily caused exists.

Some manufacturers make the electric drawer unit, add another miniature circuit breaker of a way and then join in marriage 1 set of interlocking mechanism, and the structure is complicated like this, increases two costs, and the cost is too high, and the extravagant cost does not accord with the mainstream sustainable development theory of saving at present.

Disclosure of Invention

The object of the present invention is to provide an electrically operated drawer unit which is structurally reliable and highly safe.

In order to achieve the purpose, the invention provides a high-safety electrically-operated drawer unit, which comprises a drawer type switch cabinet, wherein a drawer is provided with a bottom plate and a front panel which is positioned at the front side of the bottom plate and exposes out of a drawer hole, and the high-safety electrically-operated drawer unit is structurally characterized in that: the utility model discloses a portable electronic device, including drawer, front panel, rocking handle jack, push pedal, draw gear, push pedal fixed connection, the last lead screw that extends around rotating of drawer, be equipped with the guide holder that meshes with the lead screw in the drawer hole, run through and with the corresponding rocking handle jack of lead screw around having seted up on the front panel, install in the front panel and insert, can extract the rocking handle of rocking handle jack, be equipped with on rocking handle and the lead screw and be used for making both synchronous pivoted moment of torsion transmission mechanism, the front side horizontal sliding mounting of front panel has the limit baffle that can shelter from, can expose the rocking handle jack, the rear side horizontal sliding mounting of front panel has the push pedal, limit baffle's rear side is equipped with and is used for making both synchronous gliding shifting blocks with push pedal fixed connection.
