Abstract
The utility model relates to a kind of low-tension switch cabinet, the handle hole radical occlusion device of the drawer operation mechanism referring to especially.The utility model is by the following technical solutions: a kind of handle hole radical occlusion device of drawer operation mechanism of low-tension switch cabinet, it is characterized in that: include baffle plate, projection and push jack, wherein the middle part of baffle plate is directly or indirectly hinged in drawer support, the lower end of baffle plate and handle hole adaptation, described projection is fixedly installed on the on/off switch action bars of switch cubicle, push jack one end is hinged to be arranged on projection, on the other end, be provided with protruding conflict piece, on/off switch action bars rotates and impels projection to drive push jack to move, conflict piece moves to drive baffle plate to rotate to make to realize between the lower end of baffle plate and handle hole and separates or shutoff coordinates.By adopting such scheme, the utility model provides a kind of can block the handle hole on drawer operation mechanism when on/off switch action bars closes a floodgate, greatly improves the handle hole radical occlusion device of the novel drawer operation mechanism of safe class.
Description
Technical field
The utility model relates to a kind of low-tension switch cabinet, the handle hole radical occlusion device of the drawer operation mechanism referring to especially.
Background technology
Handle hole on the drawer operation mechanism of prior art middle-low voltage switch cabinet exposes, and and between action bars any link gear is not set, and when on/off switch action bars closes a floodgate, also there will be operating drawer operating mechanism like this, and security incident occurs.
Summary of the invention
The utility model overcomes the deficiency that prior art exists, and provides a kind of and can block the handle hole on drawer operation mechanism when on/off switch action bars closes a floodgate, greatly improves the handle hole radical occlusion device of the novel drawer operation mechanism of safe class.
In order to realize above object, this is practical newly by the following technical solutions: a kind of handle hole radical occlusion device of drawer operation mechanism of low-tension switch cabinet, it is characterized in that: include baffle plate, projection and push jack, wherein the middle part of baffle plate is directly or indirectly hinged in drawer support, the lower end of baffle plate and handle hole adaptation, described projection is fixedly installed on the on/off switch action bars of switch cubicle, push jack one end is hinged to be arranged on projection, on the other end, be provided with protruding conflict piece, on/off switch action bars rotates and impels projection to drive push jack to move, conflict piece moves to drive baffle plate to rotate to make to realize between the lower end of baffle plate and handle hole and separates or shutoff coordinates.
By adopting such scheme, we can make breaking-closing operating bar in the time of closing position, synchronously drive the lower end of baffle plate to block the handle hole of drawer operation mechanism, make handle hole be inserted and to operate by instrument, have greatly improved safe class.
Further setting of the present utility model is: the hinged place of described baffle plate and drawer support is called pin joint, and the volume that baffle plate is positioned at pin joint below is greater than baffle plate and is positioned at the volume of pin joint top; Described push jack entirety becomes " L " shape, and end and the projection of its vertical edge are hinged, and the bottom surface of its horizontal edge is plane, and described conflict piece is folded and formed by horizontal edge one end of push jack.
By adopting such scheme, we adopt the gravity of thrust and baffle plate self to realize separating and blocking of baffle plate and handle hole, and total has been simplified like this, and push jack adopts said structure in addition, the bottom surface of its horizontal edge can be used as slip plane, facilitates the slippage of push jack.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is the be blocked structural representation of state of the handle hole of the utility model embodiment;
Fig. 2 is the structural representation that the handle hole of the utility model embodiment exposes state.
Embodiment
As shown in Fig. 1-Fig. 2, a kind of handle hole radical occlusion device of drawer operation mechanism of low-tension switch cabinet, include baffle plate 1, projection 2 and push jack 3, wherein the middle part of baffle plate 1 is directly or indirectly hinged in drawer support 4, the lower end of baffle plate 1 and handle hole 5 adaptations, described projection 2 is fixedly installed on the on/off switch action bars 6 of switch cubicle, push jack 3 one end are hinged to be arranged on projection 2, on the other end, be provided with protruding conflict piece 31, on/off switch action bars 6 rotates and impels projection 2 to drive push jack 3 to move, conflict piece 31 moves to drive baffle plate 1 to rotate to make to realize between the lower end of baffle plate 1 and handle hole 5 and separates or shutoff coordinates.By adopting such scheme, we can make breaking-closing operating bar 6 in the time of closing position, synchronously drive the lower end of baffle plate 1 to block the handle hole 5 of drawer operation mechanism, make handle hole 5 be inserted and to operate by instrument, have greatly improved safe class.
In the utility model embodiment, described baffle plate 1 is called pin joint 41 with the hinged place of drawer support 4, the volume that baffle plate 1 is positioned at pin joint 41 belows 11 is greater than baffle plate 1 and is positioned at the volume of pin joint 41 tops 12, realize separating and blocking of baffle plate 1 and handle hole 5 by the gravity of thrust and baffle plate 1 self like this, Shi Gai mechanism overall simplification, described push jack 3 entirety become " L " shape, the end of its vertical edge 32 and projection 2 are hinged, the bottom surface 331 of its horizontal edge 33 is plane, and described conflict piece 31 is folded and formed by horizontal edge 33 one end of push jack 3.
