It states driving plate 21 and applies the biasing force mobile to 11 side of drawer panel, the reset spring 23 is pressed in the press-side 22
After pressure, that is, after acting on the external force disappearance on press-side 22, the drive of driving plate 21 can be driven to press by its biasing force
Pressure side 22 recoils to initial position.
As a kind of preferred embodiment, it is provided on the baffle at fixed 5 both ends of bracket and is suitble to the driving plate 21
The through-hole structure 51 to stretch through, the through-hole structure 51 also play position-limiting action to the driving plate 21, avoid the driving plate 21
Stress shakes run-off the straight, guarantees the consistency of 21 direction of motion of driving plate.
In conjunction with shown in Fig. 2 and Fig. 4, the holding tank for being suitble to accommodate the reset spring 23 is formed in the driving plate 21
24, the spring base 25 extended along the first direction is provided in the holding tank 24, one end of the reset spring 23 is arranged
On the spring base 25, the other end is connected on the baffle of described 5 one end of fixed bracket, and design is advantageous in that in this way, is led to
It crosses spring base 25 and installation positioning action is played to reset spring 23, guarantee that the reset spring 23 will not occur in forced compression
Positional shift and bending deformation, the service life of extension spring so that driving plate 21 is after external force disappearance by reset spring 23
Biasing force can realize and automatically reset.
It elaborates below with reference to the specific set-up mode of Fig. 1-4 pairs of locking structures 3:
As shown in Figs 1-4, the locking structure 3 passes through guide frame 6 and 21 slidable connection of driving plate, and along vertical
It is directly slided in the direction of 1 bottom of drawer cabinet body, the bottom of the drawer cabinet body 1 is provided with opposite with the locking structure 3
The lockhole 31 answered, the locking structure 3 is the straight panel structure that sliding is extended through in the lockhole 31, while being set on switch cabinet
Lock hole corresponding with the lockhole 31 is set, the lockhole 31 and the lock are extended through by straight panel structure sliding in this way
Determine in hole, realizes the locking and unlock to switch cabinet drawer.
As a kind of preferred embodiment, the guide frame 6 includes being set to institute along 3 glide direction of locking structure
State the vertical guide groove 61 on fixed bracket 5, and tilt upward along the first direction be set to it is oblique in the driving plate 21
To guide groove 62, and the connecting hole 63 being arranged on the locking structure 3, and pass through the connecting hole 63, slidable connection
Bolt 64 in the vertical guide groove 61 and the oblique guide groove 62, the bolt 64 pass through connecting hole 63 and locking knot
The linkage setting of structure 3, this structure setting, the driving plate 21 will drive bolt 64 when mobile diagonally guide groove 62 slides, together
When the sliding of bolt 64 is ultimately converted to reciprocatingly sliding on vertical direction under the guiding role of vertical guide groove 61, thus
Locking structure 3 is driven to move up and down, i.e., the described locking structure 3 glides along the direction perpendicular to 1 bottom of drawer cabinet body
Dynamic, realization locks or unlocks operation to drawer cabinet body, and structure is simple, easy to operate.
It is illustrated below with reference to working principle of the Fig. 1-2 to the drawer interlocking device of this implementation:
When the switch closes a floodgate, the electro-magnetic interlock mechanism 4 drives gag lever post 41 to be blocked in 21 one end of driving plate, thus
The press-side 22 on drawer panel can not be pressed to drive the driving plate 21 mobile, locking structure 3 penetrates drawer at this time
It is in the lock state in the lockhole of cabinet body, switch cabinet drawer is prevented to be extracted opening.
When the switch closes a floodgate, the blocking that the electro-magnetic interlock mechanism 4 drives gag lever post 41 to release to driving plate 21 is made
With driving the driving plate 21 to move into drawout cubicle body by pressing the press-side 22, and drive locking structure from institute
It states in lockhole and exits, i.e., locking structure 3 moves to unlocked state from lock state, and switch cabinet drawer unlock at this time can be opened freely
It opens.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
