Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
A kind of Propulsive interlocking device control of low voltage drawer according to an 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 mounted on connection frame, and sliding floor 5 is equipped with propulsive units 101, is equipped with position slide plate 8, position in propulsive units 101
It sets and is connected between slide plate 8 and connection frame by connecting rod 301, is provided between nut 3 and propulsive units 101 for pushing away
The screw rod 2 shifted into part 101,8 front surface of position slide plate are equipped with connection notice board, test notice board and separation notice board.Institute
It states and is connected between connecting rod 301 and position slide plate 8 by screw 802, position slide plate 8, which is equipped with, pushes slot 801, screw 802
It is placed in and pushes slot 801.It is equipped with bolt pressing plate 9 in the propulsive units 101, bolt pressing plate 9 is connected with bolt 6.The promotion part
Divide and be equipped with limit plate 15 in 101, limit plate 15 is connected with spring 1501, and 15 one end of limit plate is placed at 6 side of bolt.The limit
15 side of plate is equipped with the locking buckle 4 for locking limit plate 15.The propulsive units 101 are fixed with positioning plate 11, positioning plate
11 are 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, close
It is connected between lock connecting lever 12 and lock interlocking plate 10 by plate connecting rod, the lower end that lock interlocks plate 10 is equipped with pin, position
The top of slide plate 8 is equipped with the jack locked for accommodating pin and enforcing location slide plate 8.101 front end of propulsive units is also set
There is 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 are solid
Surely there is 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 is fixed by screw rod 2, and insertion crank handle rotates spiral shell
Bar 2 pushes nut 3, and nut 3 moves 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, thus realize the shaking into shaking out of drawer, and sliding floor 5 is motionless.
Drawer-bottom board 1 is mobile while driving position slide plate 8, and drawer-bottom board 1 is often 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, test in attached drawing 1
Notice board and separation notice board, indicate discrete state, trystate, connection status, so that real-time display drawer-bottom board 1 is reached
Position, the square hole on position slide plate 8 stirs plate-like spring 14, make drawer-bottom board 1 is every to reach a position and issue " rattling away " sound,
With auditory tone cues operator, specifically, the elastic reaction of plate-like spring 14, and collide generation sending with 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 when connection or testing position need to take out drawer (including sleeve mechanism), 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 of combined floodgate square shaft 13 drive combined floodgate connecting lever 12 and the interlocking plate 10 that closes a floodgate, position slide plate 8 is in connection, test 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 be moved down, and combined floodgate square shaft 13, which is unable to complete, to be turned
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 understood that not
A variety of change, modification, replacement and modification can be carried out to these embodiments in the case where being detached from the principle of the present invention and objective, this
The range of invention is defined by the claims and their equivalents.
