Description
Technical field
The utility model relates to a kind of tripper of drawer of low-voltage switch cabinet panel.
Background technology
The drawer of low-voltage switch cabinet unit has the service position locking and the operating function of closing the door, but in the existing design, drawer is when the service position, and panel can not be opened.The thing followed has also just produced following two problems:
1, when the inner interlocking of drawer unit lost efficacy, the service position locking can't be removed.Drawer can't shift out from the service position.
2, when the inner power transmission shaft of drawer came off, main switch can not separating brake under the panel closed condition.This moment, drawer can not be pulled out in cabinet by bringing onto load, otherwise very easily caused the arcing accident.
Summary of the invention
In order to solve the problem of above existence, the utility model provides a kind of drawer panel emergency unlocking device, and its technical scheme of taking is:
This device comprises and colludes plate, knocker, alignment pin, stage clip, plastics blocking piece and cylinder, collude on the right side inwall that plate is fixed on drawer panel, collude the hypotenuse of bottom front for tilting of plate to the right, the rear end is inside draw-in groove, cylinder and alignment pin are separately fixed at the middle part and the bottom of drawer right front edge of board, the medium position of knocker has slotted hole, have fixing hole in the bottom bending of knocker, the front end of cylinder passes slotted hole, fixing hole is passed on the top of alignment pin, the upper edge of the left side bending of knocker may be stuck in the bottom draw-in groove that colludes plate, compression spring sleeve is on alignment pin and be positioned at below the fixing hole, have circular hole on the drawer panel, circular hole be positioned at the bending of knocker left side the upper edge directly over, the plastics blocking piece gets lodged in the circular hole.
When drawer unit is in normal operating conditions, by the stage clip effect, collude plate and the knocker snapping is firm, drawer panel is closed solid and reliable; Come off in inner interlocking inefficacy of drawer of low-voltage switch cabinet or the inner power transmission shaft of drawer, when drawer unit is in malfunction, can open drawer panel easily, be convenient to fix a breakdown, make things convenient for plant maintenance by this device.Characteristics such as this device has simple in structure, flexible operation, and it is reliable to interlock.
Description of drawings
Fig. 1 is the overall structure figure of drawer unit in the utility model;
Fig. 2 is the structural representation of the utility model when drawer panel is closed;
Fig. 3 is the structural representation of the utility model when the drawer panel emergency release.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As depicted in figs. 1 and 2, collude plate 1 pressure welding on the inwall of the right side of drawer panel 6, collude the hypotenuse of bottom front for tilting of plate 1 to the right, the rear end is inside draw-in groove, alignment pin 3 rivet clasps are in the front bottom end of drawer right plate 7, its tapered end upwards, two cylinders 8 are separately fixed at the front center of drawer right plate 7, the medium position of knocker 2 has two slotted holes 9, left side bending and bottom bending are arranged on the knocker 2, and the front end that has 10, two cylinders 8 of fixing hole in its middle and lower part bending passes each self-corresponding slotted hole 9 respectively, fixing hole 10 is passed on the top of alignment pin 3, stage clip 4 be enclosed within on the alignment pin 3 and be positioned at fixing hole 10 below.Have circular hole 11 on the drawer panel 6, circular hole 11 be positioned at knocker 2 left side bendings the upper edge directly over, plastics blocking piece 5 gets lodged in the circular hole 11.
When normal drawer panel 6 is closed, collude plate 1 and inwardly insert with drawer panel 6, its hypotenuse pushes the upper edge of the left side bending of knocker 2 downwards, make knocker 2 along cylinder 8 to lower slider, the bottom squeeze stage clip 4 of knocker 2; After drawer was closed and put in place, under the effect of stage clip 4, knocker 2 resetted, and the upper edge of the left side bending of knocker 2 is stuck in the draw-in groove that colludes plate 1 at this moment, and cylinder 8 is stuck in the bottom of slotted hole 9, and they are fixed on off-position with drawer panel.
As shown in Figure 3, when drawer panel 6 needs emergency release, take off the plastics blocking piece 5 on the circular hole 11, from circular hole 11, insert in the drawer unit a flat mouthful screwdriver 12, with the upper edge of flat mouthful screwdriver 12 to the left side bending that presses down knocker 2, make knocker 2 to lower slider, push stage clip 4 simultaneously, when knocker 2 withdraws from the draw-in groove that colludes plate 1 fully, pulling right side drawer handle 13, drawer panel 6 can be opened around left side hinge uranium, and last under the effect of stage clip 4 elastic force, stage clip 4 and knocker 2 automatically reset.
