Interior drawer and drawer base is generally included, circuit element etc. is generally arranged in interior drawer, and drawer base sets drawer in realization
The switch member of middle circuit element ON operation, three kinds of different special state positions are provided between interior drawer and drawer base,
Respectively separation point position, half turned-on position and full on-position, separation point position are the position that circuit is fully disconnected, can in the position
So that switch cabinet drawer storehouse drawer to be pulled out, attended operation is carried out to the component in drawer and circuit, avoids triggering danger, half
On-position, equipment loop feature conducting, can use as test circuit, also be called test mode, be taken out at the position
Drawer does not allow to pull out, and full on-position is represented under the location status, and circuit is in can be with the state of fully switched on work, after combined floodgate
On-position can be also called with normal work, in this condition, drawer does not allow to pull out, and Simultaneous Switching cabinet drawer storehouse also has will
Ask, while these three special state positions are referred to as operating position, in power on circuitry, in order to ensure safe to use not allow
Other operations in addition to power-off are carried out to switch cabinet drawer storehouse, while existing switch cabinet drawer storehouse is difficult to do not pulling out entirely
These three position adjustments are realized in the case of drawout cubicle, are not convenient to use, while integral protection grade is not also high, easily causes dirt
Angstrom or other impurities enter drawout cubicle, reduce the service life of equipment.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of interlocking device for switchgear drawer, and its is rational in infrastructure, full
The interlock requirement in sufficient switch cabinet drawer storehouse, and drawer and drawer base in can carrying out in the case where not pulling out whole drawer
Between position conversion.
The utility model provides a kind of interlocking device for switchgear drawer, including switch cabinet drawer storehouse and drawer, the switch
Rotated on cabinet drawer storehouse and be provided with release knob, the drawer is slidably arranged in switch cabinet drawer storehouse, is provided with the drawer

The retaining mechanism that drawer can not pull out from switch cabinet drawer storehouse, it is provided with the drawer base for driving interior drawer in drawer
Middle to slide the power-assisted displacement governor motion for changing diverse location state between drawer base and interior drawer, the power-assisted shifts regulation machine
Structure includes regulation screw mandrel and slip base, the slip base are fixedly connected with interior drawer, and connecting seat, institute are provided with the slip base
State regulation screw mandrel to be rotatably located on connecting seat and with connecting seat screw thread coordinate, fixation is provided with the drawer base
Seat, the regulation screw mandrel are spindle rotationally arranged in fixed seat, are provided with the switch cabinet drawer storehouse for driving regulation silk
The handle that bar rotates, it is additionally provided with the drawer base for drawer movement in being promoted in each operating position limitation slip base
Position-limit mechanism, be additionally provided between release knob and the drawer base position limitation release knob beyond operating position close a floodgate or
The locking mechanism that drawer slides in limitation after release knob combined floodgate.
The beneficial effect so set is：Using such scheme, drawer separation is arranged to interior drawer and drawer base
Form, drawer base house circuit switch element, both divide the work clearly, it is not easy to occur based on operating mechanism in interior drawer
The phenomenon that circuit tangles, meets the requirement of Electrical Safety, and by rotating the handle on drawer panel so that regulation screw mandrel turns
It is dynamic, because regulation screw mandrel is spindle rotationally arranged in fixed seat, screw mandrel will be adjusted and be plugged in fixed seat, and in fixed seat two
End sets limited block to limit the front and rear sliding of regulation screw mandrel, realizes that the rotation of regulation screw mandrel does not slide, due to regulation screw mandrel
Rotate, connecting seat moves forward and backward with screw thread, drives the slip base with connecting seat fixed setting to slide, due to slip base and interior drawer
It is fixedly connected, so as to which transfer of the drawer between three separation point position, half turned-on position and full on-position positions is slided in push-and-pull,
Separation point position, half turned-on position and the conversion of these three operating positions of full on-position are realized, while this conversion regime need not
Drawer is extracted out, can be carried out outside switch cabinet drawer storehouse, so as to improve the degree of protection of switch cabinet drawer storehouse drawer so that
Pollutant dust etc. is not easily accessible drawer, while operates also very simple, and structure is reliable and practical, and in these three operating positions
Position-limit mechanism is also set up in upper drawer base, it is ensured that locking of the interior drawer in operating position is spacing, does not slide, so as to
Circuit attended operation is carried out, limit method can use and lock pin pair is ejected when slip base slides into each operating position correspondence position
The limitation that is rotated of regulation screw mandrel, can also well directly by the limitation mode of sliding of the lock pin to slip base, and according to
The operation requirement in switch cabinet drawer storehouse, switch cabinet drawer storehouse switch do not allow to adjust state position, switch cabinet drawer in operation
It is additionally provided with locking mechanism on storehouse, locking mechanism can set jack in operating position correspondence position on slip base, then by
The latch that control is rotated by release knob plugs in jack, realizes locking and unblock, meets the operation requirement in switch cabinet drawer storehouse, full
The interlock requirement in sufficient switch cabinet drawer storehouse, and drawer and drawer base in can carrying out in the case where not pulling out whole drawer
Between position conversion, improve the service efficiency of equipment.
The utility model, which is further arranged to the position-limit mechanism, includes interlocking latch, latch frame and limiting plate, described spacing
Plate is fixedly installed on slip base side, and the distance that corresponding to drawer interior at each operating position on the limiting plate need to slide is provided with
For the stopper slot of interlocking latch insertion, the latch frame is arranged on drawer base, and the interlocking latch is slidably arranged on latch frame,
