The lower end surface of the present embodiment lock tongue 31 is configured to from front to back the cambered surface 311 of rounding off gradually downward, when mandril 2
Upper end when being in contact with lock tongue 31, globoidal structure can avoid lock tongue 31 and cause to interfere to 2 state of moving up of mandril.Setting should
Structure and above-mentioned second sliding block 52 are primarily to the upper plate of lock tongue and door body to lockplate 3 is formed and protected, and mandril 2 is to moving up
Under dynamic state, when latched position of the position that mandril 2 moves up slightly above lock tongue 31, if being not provided with the second sliding block 52, top
The power of bar 2 can be directly passed to lock tongue 31, be easy to cause 31 deformation or damage of lock tongue, and after the second sliding block 52 is set, mandril 2 exists
Into after latched position, the upper end of mandril 2 offsets with 52 inclined-plane 521 of the second sliding block, to pass through the second sliding block 52 for mandril 2
The power that driving lock tongue 3 moves backward is dispersed and be converted into upward power, and lock tongue 31 is avoided to damage, meanwhile, also avoid mandril 2
Motion process exerts a force to the upper plate of door body, influences door body structure.
In the present embodiment, switch block 7 includes electromagnetic signal automatic unlocking mechanism 71, button 72 and the second elastic component
73, electromagnetic signal automatic unlocking mechanism 71 connect with controller electric signal and can independently drive and slides before and after the first sliding block 6.Button
72 can be set to the front side of the first sliding block 6 movably forward and backward, and button 72, which moves backward, drives the first sliding block 6 to move backward under state,
Second elastic component 73 is set between button 72 and the first sliding block 6 and button 72 is made to be to remain forward movement ground trend.Setting
Above structure can be by the on & off switch that is set on cleaning machine panel to controller signals under normal operating condition, then passes through control
Device issues signal to electromagnetic signal automatic unlocking mechanism 71, carries out auto-unlocking using electromagnetic signal automatic unlocking mechanism 71；And
In the power-off state, so that it may be unlocked by button 72 and the cooperation of the second elastic component 73, take into account Electronic control and machinery
Two ways is controlled, it is safer and more reliable.
Specifically, electromagnetic signal automatic unlocking mechanism 71 is set to the side of mounting plate 1 and arranges close to the first sliding block 6, electricity
The slide bar 712 that magnetic signal automatic unlocking mechanism 71 is including ontology 711 and on ontology 711 and vertical first sliding block 6 of energy is flexible,
Cooperation can be oriented to slide by the driving first that moves left and right of slide bar 712 by being correspondingly arranged on the slide bar 712 and the first sliding block 6
The fit structure that block 6 is moved forward and backward.The upper surface of first sliding block 6 offers V-arrangement sliding slot 60, the first side 601 of the V-arrangement sliding slot 60
It being laterally extended from left to right, the second side 602 of the V-arrangement sliding slot 60 gradually extends forward from left to right, and it is corresponding, slide bar 712
The guide post 7121 that can be plugged in the V-arrangement sliding slot 60 is provided on lower wall surface.Guide post 7121 is collectively formed with V-arrangement sliding slot 60
Above-mentioned fit structure.It is moved left and right since the first sliding block 6 can only be moved forward and backward without can be carried out, it hangs down in slide bar 712
When straight first sliding block 6 is mobile, under the constraint of V-arrangement sliding slot 60, the first sliding block 6 can be moved forward and backward under the driving of slide bar 712, from
And whether realizing unlock.
The rear end of button 72 has the first extended column 721 for extending back, corresponding, the front end of the first sliding block 6 have to
Second extended column 62 of preceding extension, the second elastic component 73 are that end is nested with respectively on the first extended column 721, the second extended column 62
Spring, and the first end of the spring and the rear end face of button 72 offset, the front end face phase of the second end of spring and the first sliding block 6
It supports.When above-mentioned first extended column 721 and the second extended column 62 offset, the first sliding block 6 can be pushed to move back by button 72, to drive
Dynamic lockplate 3 moves back, and realizes unlock.
The locking structure of the present embodiment can be realized by purely mechanic fit structure, and electromagnetic signal automatic unlocking also may be implemented
Mechanism realizes unlock, relies on automatically controlled logic low；When needing to lock, 2 upper end of mandril is moved up, and is passed to by lock tongue 31
The thrust of lockplate 3 backward, after mandril 2 moves up, lockplate 3 moves forward under the effect of the first elastic component 4 and makes lock tongue 31
It is plugged in the fore shaft 21 of mandril 2, completes locking；When needing to unlock, the first sliding block 6 is driven to move backward by switch block 7,
To drive lockplate 3 to move back by trigger assembly 5, exit lock tongue 31 in fore shaft 21, at this point, mandril 2 can exit downwards lock
Hole 11 completes to unlock.
