Description
Technical field
The utility model belongs to technical field of electric equipment, especially a kind of interlock of switch cabinet drawer storehouse drawer.
Background technology
Switch cabinet drawer storehouse is a kind of electrical equipment, and the different drawer of all size model is set on switch cabinet drawer storehouse,
Different circuit controllers is set respectively in each drawer, so as to carry out master control, drawer structure to circuit by switch cabinet drawer storehouse
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, the circuit in drawer is operated, avoids triggering danger, should in half turned-on position
Equipment loop feature turns on, and can be used as test circuit, also be called test mode, drawer does not allow to draw at the position
Go out, full on-position is represented under the location status, and circuit is in can be with the state of fully switched on work, can normal work after combined floodgate
Make, be also called on-position, in this condition, drawer does not allow to pull out, and Simultaneous Switching cabinet drawer storehouse also requires, at the same by this
Three special state positions are referred to as operating position, in power on circuitry, in order to ensure safe to use not allow to take out switch cubicle
Drawer storehouse carries out other operations in addition to power-off, while existing switch cabinet drawer storehouse is difficult to do not pulling out the feelings of whole drawout cubicle
These three position adjustments are realized under condition, are not convenient to use, while integral protection grade are not also high, easily cause dust or other
Impurity enters drawout cubicle, reduces 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 drawer
Upper rotation is provided with release knob, and the drawer is slidably arranged in switch cabinet drawer storehouse by slipping mechanism, in the drawer
Interior drawer and drawer base is provided with, the interior drawer is slidably disposed in drawer, and use is provided with the drawer base
It is used to drive interior drawer in being provided with the retaining mechanism for making drawer can not pull out from switch cabinet drawer storehouse, the drawer base
The power-assisted displacement governor motion for changing diverse location state between drawer base and interior drawer, the power-assisted displacement are slided in drawer
Governor motion includes regulation screw mandrel and slip base, the slip base are fixedly connected with interior drawer, the company of being provided with the slip base
Joint chair, the regulation screw mandrel are rotatably located on connecting seat and coordinated with connecting seat screw thread, set in the drawer base
There is fixed seat, the regulation screw mandrel is spindle rotationally arranged in fixed seat, is provided with the drawer for driving regulation screw mandrel
The handle of rotation, the limit for drawer movement in being promoted in each operating position limitation slip base is additionally provided with the drawer base
Position 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 closes a 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
