The utility model adopts the screw mandrel drive mechanism to drive the lock claw executing mechanism, thereby play locking by the effect of latch fitting, the L type chute of lock pawl, making the hook portion of lock pawl is the locking mode that oriented side has downward motion again, touches travel switch, when being arrived certain position by latch fitting, the locking of mechanism auto-action by latch fitting in the appropriate location, avoided conventional seals every lock to need artificial pretension after, Suo Jin situation again, but and when accident has a power failure emergency opening, thereby guarantee the safe handling of all kinds of related occasion.
The utility model has the advantages that and initiatively to lock, and coupling mechanism force is big.
Description of drawings
Fig. 1 is a door lock assembly opening structural representation;
Fig. 2 is a door lock assembly locking state structural representation;
Fig. 3 is door lock assembly release conditions structural representations.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be door lock assembly opening structural representation, form by lock pawl 1, block 2, big spring 3, deceleration device 4, vertical axis 5, upper stroke switch 6, fixture block 7, little spring 8, right lateral journey switch 9, lower stroke switch 10, rope 11, frame 12, screw mandrel 13, guide pad 14.
With the circle hole sleeve of lock on the pawl 1 on vertical axis 5, they can relatively rotate, a L shaped groove cover on the lock pawl 1 is fixed on the frame 12 by straight pin, upper stroke switch 6 places the top of frame 12, be connected with lock pawl 1, big spring 3 is connected in block 2 and deceleration device 4, guide pad 14 on the frame 12 places between block 2 and the deceleration device 4, screw mandrel 13 is installed in the gathering sill in the guide pad 14, deceleration device 4 is done relative motion along the screw mandrel axis direction by motor-driven and screw mandrel 13 in guide pad 14, screw mandrel 13 heads are fixed with on the vertical axis 5 perpendicular to screw mandrel, one end of block 2 is fixed on the frame 12 by straight pin, the other end is embedded in the draw-in groove of the fixture block 7 that is positioned at screw mandrel 13 1 sides, a circular hole on the fixture block 7 is fixed on the frame 12 by straight pin, and can rotate around straight pin, stretch out a cantilever on the fixture block 7 and connect little spring 8 and rope 11 respectively, the other end of little spring 8 is connected with frame 12.
On the extension ditch on being fixed on door touched upper stroke switch 6 by the latch fitting lower edge time, control system is sent instruction and is driven screw mandrel 13 positive action, because the effect deceleration device 4 of resistance moves up earlier and contacts with block 2, and block 2 is blocked by fixture block 7, deceleration device 4 can not move upward again, screw mandrel 13 and vertical axis 5 fixed thereon are to lower slider then, driving lock pawl 1 moves down, do relative slip along the L shaped groove on it with the straight pin on being fixed on frame simultaneously, make the other end of L shaped groove slide to straight pin, when the travel switch 10 that is installed in the bottom is touched in the lower end of screw mandrel 13, control system is sent instruction and is given deceleration device 4, screw mandrel 13 stops action, and lock pawl 1 and be in locking state this moment.
As shown in Figure 2, be door lock assembly locking state structural representation,, drive screw mandrel 13 counteragents when control system is sent the instruction of opening the door.Deceleration device 4 is moved downward to the gathering sill bottom along the gathering sill on the frame, deceleration device 4 can not be moved down again, screw mandrel 13 and vertical axis 5 drive lock pawls 1 fixed thereon move up then, straight pin on locking the L shaped groove of pawl on 1 along its simultaneously and being fixed on frame is done relative slip, makes the other end of L shaped groove slide to straight pin.Thereby discharge by latch fitting.
As shown in Figure 3, be door lock assembly release conditions structural representation, when equipment loses supply of electric power, can be manually opened, at this moment spur the rope 11 on the fixture block 7 downwards, make fixture block turn to certain position, an end of block 2 can be deviate from the draw-in groove of fixture block 7 at this moment, block 2 can rotate around the straight pin that is fixed on the frame, and screw mandrel 13 transmission device integral body move up under the effect of spring force, moves up thereby drive lock pawl 1, straight pin on locking the L shaped groove of pawl on 1 along its simultaneously and being fixed on frame is done relative slip, make the other end of L shaped groove slide to straight pin, thereby discharge, right lateral journey switch 9 is discharged by latch fitting.When system again electric after, control system detects travel switch 9 and has discharged, can only send the instruction of opening the door, drive screw mandrel 13 counteragents, because of the vertical axis 5 that is fixed on the screw mandrel 13 is collided with the top of frame gathering sill, can't move up, screw mandrel 13 transmission devices promote deceleration device 4 and move down, and drive block 2 and rotate around straight pin, fixture block 7 is in the effect turning down of spring force simultaneously, one end of block 2 is returned in the draw-in groove of fixture block 7, thereby makes entire mechanism be reset to normal opening.
