The technical scheme is that: the visible breakpoint isolation box safety interlocking mechanism comprises a base plate (1), a bracket (2), a guide pillar (4), a pressing plate (5), a hook plate (8), a spring (9) and a slide plate. The bracket (2) presents to be inverted-U-shaped. The pressing plate (5) bestrides the bracket (2) and is connected with the slide plate in the bracket (2). The spring (9) is arranged below the slide plate and sleeved on the guide pillar (4). The guide pillar (4) is fixed on the base plate (1) which is fixedly connected with the bracket (1). One end of the hook plate (8) is fixed on the bracket (2), and the other end is arranged on the pressing plate (5). The beneficial effects of the visible breakpoint isolation box safety interlocking mechanism are that: whole course interlocking of a visible breakpoint isolation box before closing is realized, safety of operation is greatly enhanced, processing and manufacturing difficulty and cost are reduced, a production period is shortened, structure is simple and occupied space is small.
Description
Technical field
The utility model relates to a kind of visual breakpoint shielded box safety interlock for overhead, belongs to industrial power distribution equipment technical field.
Background technology
At present, domestic visual breakpoint shielded box VCS product all has safety interlock for overhead, safety interlock for overhead is the most important Yi Ge mechanism of visual breakpoint shielded box VCS product, aspect security protection, play vital effect, and existing product has the following disadvantages in actual applications, the one, before switch disjunction, can not omnidistance interlock, therefore there is certain potential safety hazard; The 2nd, casing is generally complete enterprise and manufactures, and complete enterprise majority be take panel beating production as main, and these enterprises are bad at the manufacturing of non-sheet metal part, therefore make manufacturing cost very high.
Utility model content
The utility model object is to provide a kind of visual breakpoint shielded box safety interlock for overhead, realizes the front omnidistance interlocking of visual breakpoint shielded box separating brake, improves the fail safe of operation, the problem existing in solution background technology.
The technical solution of the utility model is:
A kind of visual breakpoint shielded box safety interlock for overhead, comprise base plate, support, guide pillar, pressing plate, hook plate, spring and slide plate, support is inverted U, and pressing plate passes from support top, and is connected with the slide plate in support, slide plate below is provided with spring, spring housing is on guide pillar, and guide pillar is fixed on base plate, and base plate is fixedly connected with support, hook plate one end and be fixed on support, the other end is located at pressing plate outside.
Described slide plate comprises slide plate A and slide plate B, and slide plate A and slide plate B are arranged in pairs in support, and are connected with pressing plate.
Described guide pillar is four, on each guide pillar, is equipped with spring, pressuring spring below slide plate A, and spring is set to symmetrical structure with force balance, prevents clamping stagnation.
On three faces of described inverted U support, be equipped with bar hole.Pressing plate can slide up and down in bar hole, drives slide plate A to slide up and down along the bar hole on side simultaneously.
Hook the centre that plate one end is fixed on support, during use, square shaft is through the square hole above it, and the other end is located on pressing plate outside.
Adopt the utility model, when hooking plate and depress pressing plate and move down, in the circular hole of square shaft on slide plate A and slide plate B, now can operate square shaft and clockwise rotate operating breaker and close a floodgate, after closing a floodgate, hook the hook plate arranging on plate and door-plate and mutually link, lock door-plate.When door-plate is opened, due to the reset force effect of spring, slide plate A and slide plate B and pressing plate are moved up, in the square hole of square shaft on slide plate A and slide plate B, be now that after door-plate is opened, square shaft is locked by operating mechanism, avoiding people is misoperation circuit breaker, assurance equipment and personal safety.
The beneficial effects of the utility model are: before realizing visual breakpoint shielded box separating brake, whole process is interlocked, and greatly improves the fail safe of operation, reduction processing and manufacturing difficulty and expense, and the shortening production cycle, simple in structure, take up room little.
