Abstract
The utility model relates to a position-limit mechanism of a switch cabinet instrument door. The position-limit mechanism comprises a U-shaped lock catch arranged transversely, two sides of an opening end of the U-shaped lock catch are hinged to a side part of a switch cabinet instrument chamber, the inner side of the instrument door is provided with a shaft body penetrating the middle of the U-shaped lock catch, the shaft body can slide in an U-shaped groove of the U-shaped lock catch, an end of the shaft body is provided with a circular stop block, and the diameter of the circular stop block is greater than the width of the U-shaped groove. The position-limit mechanism of the switch cabinet instrument door has the advantages of reasonable design, simple structure and low manufacturing cost; and the position-limit mechanism of the switch cabinet instrument door can effectively limit a position of the instrument door, prevent the instrument door from generating swings or shaking and prevent the instrument door from being opened too large to collide with a cabinet body.
Description
Technical field
The utility model relates to a kind of switch cubicle instrument door position-limit mechanism.
Background technology
The control room of switch cubicle is usually located at the top of switch cubicle, in the time opening instrument door, because it does not obtain spacingly, make instrument door easily occur swinging and encounter staff's head, simultaneously instrument door often because open excessively make leading flank encounter cabinet and produce damaged in collision.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of simple in structure, can effectively carry out the switch cubicle instrument door position-limit mechanism of position-limiting action to the switch cubicle instrument door of opening.
The utility model adopts following scheme to realize: a kind of switch cubicle instrument door position-limit mechanism, comprise and be horizontally arranged with U-shaped snap close, described U-shaped latch openings end both sides are articulated with the sidepiece of switch cabinet instrument room, described instrument door inner side is provided with through the axis body in the middle of U-shaped snap close, described axis body can slide in the U-lag of U-shaped snap close, described axis body end is provided with circular guide vane end stop, and the diameter of this circle guide vane end stop is greater than described U-lag width.
Further, the width of described U-shaped snap close is diminished to blind end gradually by its openend, and described U-shaped latches near its blind end position and is provided with necking down.
Further, on described axis body, offer screwed hole, on described guide vane end stop, offer bolt hole, described guide vane end stop is connected by screw and is fixed on described axis body end.
Compared with prior art, the utlity model has following beneficial effect: this switch cubicle instrument door position-limit mechanism is reasonable in design, simple in structure, manufacturing expense is low, can effectively carry out spacingly to instrument door, avoid it to produce and swing or rock, prevent that it from opening excessive and bumping with cabinet simultaneously.

Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below will, by specific embodiment and relevant drawings, the utility model be described in further detail.
As shown in Fig. 1 ~ 3, a kind of switch cubicle instrument door position-limit mechanism, comprise and be horizontally arranged with U-shaped snap close 1, described U-shaped snap close 1 openend both sides are articulated with the sidepiece of switch cabinet instrument room 2, described instrument door 3 inner sides are provided with through the axis body 4 in the middle of U-shaped snap close 1, described axis body 4 can slide in the U-lag of U-shaped snap close 1, described axis body 4 ends are provided with circular guide vane end stop 5, the diameter of this circle guide vane end stop 5 is greater than described U-lag width, make the instrument door of switch cubicle in the time opening, can obtain spacing, U-shaped snap close 1 blind end can be held the axis body on instrument door 3, to prevent that thereby the cabinet of encountering too greatly that instrument door 3 is opened from producing the head that is out of shape or meets staff.
In the present embodiment, the width of described U-shaped snap close 1 is diminished to blind end gradually by its openend, described U-shaped snap close 1 is being provided with necking down 6 near its blind end position, described U-lag is positioned at width that this place's necking down 6 goes out and is slightly less than the diameter of described axis body 4, make after instrument door is opened, described axis body 4 can be blocked by described necking down 6, prevents that swinging or rocking from appearring in instrument door, while closing instrument door 3, only need to slightly firmly can make axis body 4 depart from necking down 6.
In the present embodiment, on described axis body 4, offer screwed hole, on described guide vane end stop, offer bolt hole, described guide vane end stop 5 is fastened on described axis body 4 ends by screw 7, between described screw 7 and guide vane end stop 5, is also provided with packing ring.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; institute is understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
