A kind of Propulsive interlocking device control of low voltage drawer according to the ... of the embodiment of the present invention is described below with reference to Fig. 1 to Fig. 5
Principle processed, including drawer-bottom board 1 and sliding floor 5, sliding floor 5 are placed in drawer-bottom board 1, and drawer-bottom board 1 is fixed with nut
3, nut 3 is equipped on link, and sliding floor 5 is equipped with propulsive units 101, and position slide plate 8 is equipped in propulsive units 101,
It is connected by connecting rod 301 between position slide plate 8 and link, by being used to push away between nut 3 and propulsive units 101
The screw rod 2 shifted into part 101,8 front surface of position slide plate are equipped with connection notice board, experiment notice board and separation notice board.Institute
It states and is connected by screw 802 between connecting rod 301 and position slide plate 8, position slide plate 8, which is equipped with, pushes slot 801, screw 802
It is placed in and pushes slot 801.Bolt pressing plate 9 is equipped in the propulsive units 101, bolt pressing plate 9 is connected with bolt 6.The promotion part
Divide and be equipped with limiting plate 15 in 101, limiting plate 15 is connected with spring 1501, and 15 one end of limiting plate is placed at 901 side of bolt.The limit
Position 15 side of plate is equipped with the locking buckle 4 for locking limiting plate 15.The propulsive units 101 are fixed with positioning plate 11, positioning
Plate 11 is equipped with combined floodgate square shaft 13, and combined floodgate square shaft 13 is connected with combined floodgate connecting lever 12, and 11 front surface of positioning plate is equipped with lock and interlocks plate 10,
Combined floodgate connecting lever 12 is connected between interlocking plate 10 with lock by plate connecting rod, and the lower end that lock interlocks plate 10 is equipped with pin, position
The top for setting slide plate 8 is equipped with the jack locked for housing pin and enforcing location slide plate 8.101 front end of the propulsive units is also
Equipped with plate-like spring 14, position slide plate 8 is equipped with vacancy 1401, and plate-like spring 14 is placed at vacancy 1401.The propulsive units 101
It is fixed with junction block 7.
The realization of the propulsion drawer of this structure：Nut 3 is fixed on drawer-bottom board 1, and 2 one end of screw rod is fixed on propulsive units
101, propulsive units 101 are fixed on sliding floor 5, and the bolt 6 on sliding floor 5 fixes screw rod 2, are inserted into crank handle and rotate spiral shell
Bar 2 pushes nut 3, nut 3 to be moved on sliding floor 5 together with drawer-bottom board 1.Drawer-bottom board 1 drives entire drawer together
It is moved forward and backward on specified guide rail, to realize the shaking into shaking out of drawer, and sliding floor 5 is motionless.
Drawer-bottom board 1 moves while position slide plate 8, drawer-bottom board 1 being driven often to be moved to a position, and position slide plate 8 is all
There is corresponding position to be corresponding to it, three positions of drawer are indicated in slide plate 8 front in position, as connected notice board, experiment in attached drawing 1
Notice board and separation notice board, indicate discrete state, trystate, connection status, to which real-time display drawer-bottom board 1 is reached
Position, the square hole on position slide plate 8 stirs plate-like spring 14, so that drawer-bottom board 1 is often reached a position and send out " rattling away " sound,
With auditory tone cues operating personnel, specifically, the elastic reaction of plate-like spring 14, and sent out with the generation that collides of vacancy 1401
" rattling away " sound；Position slide plate 8 moves away disengaged position, and locking buckle 4 clasps bolt 6 under the action of the spring so that bolt pressure
Plate 9 can not up lift bolt 6, it is ensured that sliding floor 5 and can not pull out drawout cubicle in drawer-bottom board 1, such as break down and locked
Extremely drawer need to be taken out in connection or testing position（Including sleeve mechanism）When, locking buckle 4 can be pushed aside, lift 9 He of bolt pressing plate
Bolt 6, so that it may remove drawer and be safeguarded.Bolt 6 could be inserted into crank handle and shake screw rod 2 when bolt pressing plate 9 pushes locking, no
Then drawer crank handle can not interposer.Conversely, crank handle cannot then solve locking plug pressing plate 9 without dial-out screw rod 2.
The rotation drive combined floodgate of combined floodgate square shaft 13 connecting lever 12 and the interlocking plate 10 that closes a floodgate, position slide plate 8 is in connection, experiment and divides
It offs normal and sets, the interlocking plate 10 that closes a floodgate can be inserted into 8 square hole of position slide plate, and it is dynamic that combined floodgate square shaft 13 can continue rotation completion combined floodgate
Make, the interlocking plate 10 that closes a floodgate at this time blocks 2 handle hole of screw rod, can not be inserted into crank handle operation screw rod 2;As position slide plate 8 does not have
It shakes to three positions or without transfering to crank handle, the interlocking plate 10 that closes a floodgate can not move down, and combined floodgate square shaft 13 can not be completed to turn
It is dynamic.
Although an embodiment of the present invention has been shown and described, the common skill of this field is stated personnel and is appreciated that：Not
In the case of being detached from the principle of the present invention and objective a variety of change, modification, replacement and modification can be carried out to these embodiments, this
The range of invention is limited by claim and its equivalent.
