Description
Technical field
The utility model is related to interlocking device, especially a kind of electrical cabinet rear cabinet door interlock.
Background technology
Electrical cabinet is mainly used for electric energy being assigned to each load position with electric control and in short circuit, overload and electric leakage
Carry out power-off protection.General electrical cabinet includes front cabinet door, afterwards upper cabinet door and rear lower cabinet door.In order to ensure safety, generally need
First to open front cabinet door, upper cabinet door and the level-one of rear lower cabinet door are unlocked after being realized by corresponding solenoid valve control, then again into
Upper cabinet door and the two level of rear lower cabinet door are unlocked after row.The switch of the considerations of in factors such as safety, rear upper cabinet door and rear lower cabinet door
Sequencing is needed, and traditional interlock is not only more complicated, but also occupied space, take material, therefore cost is higher.
Invention content
It is simple in structure the technical problem to be solved by the utility model is to provide a kind of electrical cabinet rear cabinet door interlock,
Material is saved, space availability ratio is improved, facilitates the installation maintenance etc. of electrical equipment.
In order to solve the above technical problems, technical solution used by the utility model is：
A kind of electrical cabinet rear cabinet door interlock, including main lock body, upper hook, lower draw-bar；Main lock body includes leading for left and right
Xiang Zhu is equipped with upper limit bar, upper guide plate, bottom guide, lower limit bar between two guide posts successively from top to bottom；Wherein, upper guide plate,
Bottom guide and two guide posts are slidably matched and the other end is fixed on electrical cabinet side frame；Guiding between upper guide plate and bottom guide
Connecting rod is installed on column, is connected by resetting spring between connecting rod and upper guide plate；The upper hook, lower draw-bar are fixedly mounted respectively
In rear upper cabinet door bottom end, rear lower cabinet door apical position；Upper hook, lower draw-bar are connected with upper limit bar, lower limit bar respectively,
Upper cabinet door bottom end, rear lower cabinet door switch in order after realization.
The upper hook is equipped with the upper limit position groove being made of upper skewed slot and vertical slot, and lower draw-bar is equipped with and is made of lower skewed slot
Lower limit slot.
The upper limit bar, lower limit bar are tube-in-tube structure, and are rotatably connected with two guide posts.
Two guide post is equipped with upper guide plate limited post, and upper guide plate limited post limits upper guide plate lower end.
A kind of electrical cabinet rear cabinet door interlock of the utility model, by installing hook in rear upper cabinet door lower edge,
Lower draw-bar is installed in rear lower cabinet door upper end-face edge, vertically-mounted main lock body, utilizes automatically reseting for spring on electrical cabinet side frame
And the position-limiting action of upper limit position groove, lower limit slot is first closed and goes up lower cabinet door after cabinet door is closed again afterwards when can realize closing；When opening, first
Upper cabinet door after rear lower cabinet door is opened again is opened, this ensure that safety.In addition structure is simpler for relatively traditional interlock
Single, materials are few, save space, are conducive to the installation of later stage electrical cabinet equipment, safeguard.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is the schematic diagram of the utility model（Upper lower cabinet door does not close afterwards）.
Fig. 2 is the schematic diagram of the utility model（Upper cabinet door is closed afterwards, and rear lower cabinet door does not close）.
Fig. 3 is the schematic diagram of the utility model（Upper lower cabinet door closes afterwards）.
In figure：Main lock body 1, upper hook 2, lower draw-bar 3, guide post 4, upper limit bar 5, upper guide plate 6, bottom guide 7, lower limit
Bar 8, connecting rod 9, resetting spring 10, upper skewed slot 11, vertical slot 12, lower skewed slot 13, upper guide plate limited post 14.
Specific implementation mode
As shown in Figs. 1-3, a kind of electrical cabinet rear cabinet door interlock, including main lock body 1, upper hook 2, lower draw-bar 3；Main lock
Body 1 includes the guide post 4 of left and right, and topmost upper limit bar 5, lower limit bar 8 are equipped with bottom between two guide posts 4.On
Gag lever post 5, lower limit bar 8 are tube-in-tube structure, and are rotatably connected with two guide posts 4.Since upper limit bar 5, lower limit bar 8 are led
It plays and is locked with upper hook 2, lower draw-bar 3, therefore fretting wear can be reduced by the way that tube-in-tube structure is arranged.And in upper limit
Upper guide plate 6, bottom guide 7 are then provided in guide post 4 between bar 5, lower limit bar 8, upper guide plate 6, bottom guide 7 are by wearing
Guide post 4 is crossed, the other end is fixed on electrical cabinet side frame.Upper guide plate 6, bottom guide 7 primarily serve guiding role so that two are oriented to
Column 4 can only carry out oscilaltion movement.Connecting rod 9 is installed in the guide post 4 between upper guide plate 6, bottom guide 7, connecting rod 9 with it is upper
It is connected by resetting spring 10 between guide plate 6；It can carry out partial reset after lower cabinet door automatically after opening in this way so that guide post 4
It moves up, the unlatching of upper cabinet door to after the completion of.
The upper hook 2 is equipped with the upper limit position groove being made of upper skewed slot 11 and vertical slot 12, and lower draw-bar 3 is equipped with by oblique
The lower limit slot that slot 13 is constituted.Flume structure not only acts as the effect of limiting locking, while the inclination angle of skewed slot and length can also shadows
Ring the displacement moved to upper limit bar 5, lower limit bar 8, ensure between upper limit bar 5 and upper skewed slot 11, lower limit bar 8 with it is oblique
Upper lower cabinet door locks opening in order after matching relationship satisfaction between slot 13.
Two guide post 4 is equipped with upper guide plate limited post 14, and upper guide plate limited post 14 limits 6 lower end of upper guide plate.By
This ensures after resetting, and originally specified position is moved on in two guide posts 4 without deviation occurs.
Operation principle and process：
1）, first, the upper equal opening state of lower cabinet door afterwards：At this point, upper limit bar 5 on main lock body 1 and upper hook 2 it is upper tiltedly
11 face of slot, and lower limit bar 8 is then located at 13 upper end of lower skewed slot on lower draw-bar 3.It can only first close and go up cabinet door afterwards.
2）, then, upper cabinet door closed state afterwards：After closing when upper cabinet door, two guide posts 4 move down, upper limit bar 5 with it is upper
11 end of skewed slot coordinates, and at this point, the lower limit bar 8 on main lock body 1 and 13 face of lower skewed slot on lower draw-bar 3, resetting spring
10 generate initial tensioning power.After upper cabinet door is closed after i.e., rear lower cabinet door can also be closed.
3）, it is last, upper lower cabinet door is turned off state afterwards：After closing after upper cabinet door, then lower cabinet door is closed after carrying out.Main lock
Lower limit bar 8 on body 1 slides into lower skewed slot 13, and the end of lower skewed slot 13 is reached along the inclined-plane of lower skewed slot 13.It is same with this
When two guide posts 4 move down, the upper limit bar 5 on main lock body 1 moves down into 12 bottom end of vertical slot, to upper lower cabinet door after being finally completed
It closes, resetting spring 10 generates two times tensioning power.
When needing to open, lower cabinet door after first opening, lower limit bar 8 is skidded off out of lower skewed slot 13, while resetting spring 10
Partially retracted, under the action of elastic force, two guide posts 4 move up；In this way upper limit bar 5 also on move on to skewed slot 11 and 12 mistake of vertical slot
Place is crossed, upper cabinet door, resetting spring 10 reset after then turning on, and 6 lower end of upper guide plate is limited by upper guide plate limited post 14 so that two lead
Stop moving in vertical direction to column 4, keeps in situ and wait for close next time.
