Muscle 37 leaves fork 39, and fork 39 disappears to the power of microswitch 13, and microswitch 13 disconnects.
The assemble sequence of the safety key switch of the embodiment of the present invention is as follows：
The first step：Slide block 2 is loaded in the slide block slot 15 of button 3 it is desirable to the unblock stirring muscle 18 and button 3 of slide block 2
Hold 16 same directions；Take-up housing 4 puts on sliding block spring 1, and its guide pillar 19 is snapped in the guiding draw-in groove 21 of button 3, and by slide block
Seat 4 is mutually buckled together with slide block 2；
Second step：The guide rod 35 of rotary shaft 8 is inserted in the guide hole 32 of guide pin bushing 7, then with the no increment of guide pin bushing 7 as front portion,
It is loaded in the set hole 24 of guide pin bushing seat 6, the larger diameter end of bearing pin 9 is inserted rotary shaft 8 in the hole, lifting spring 10 is through pin
In axle 9 smaller diameter end, the pin shaft hole 38 of pedestal 12 is matched with bearing pin 9 smaller diameter end, and pedestal 12 and guide pin bushing seat 6 are used fixing screws
It is fixed together；
3rd step：With long spiro nail 14, microswitch 13 is fixed on from the pedestal 12 of lock set it is desirable to microswitch 13
Fork 39 contact with the steering muscle 37 of rotary shaft 8 inwardly；
4th step：Button guide pillar 20 will be penetrated by key spring 5, and button assembly will be assembled with the guide pin bushing seat 6 from lock set
Together.
Operation principle of the present invention：First, stir slide block 2 to the solution lock end 16 of slide block slot 15, take-up housing 4 one starts shipment therewith
Dynamic；Then, apply a power axially downwardly to button 3, the high plane 23 of take-up housing 3 is by guide pin bushing 7, rotary shaft 8, bearing pin 9 even
Band axial downward movement together, the guiding helical teeth 34 due to guide pin bushing 7 is that tooth coordinates and is staggered with the steering muscle inclined-plane 36 of rotary shaft 8
Half tooth, tooth is combined with the principle of stress decomposition, when steering muscle 37 top of rotary shaft 8 departs from high helical teeth 31 top, rotation
Axle 8 rotates a certain angle automatically, falls into the root portion of the guiding helical teeth 34 in " W " type, unclamps the power applying to button 3, rotation
Rotating shaft 8 is because by lifting spring 10 resilience force, moved axially upward, and the steering muscle inclined-plane 36 due to rotary shaft 8 and guide pin bushing seat 6
High helical teeth 31 inclined-plane be tooth cooperation, tooth be combined with stress decomposition principle, rotary shaft 8 rotates a certain angle automatically, falls into
The root portion of high helical teeth 31, now for self-locking state, after angle rotation twice, it turns to muscle 37 and just will rotary shaft 8
Fork 39 is depressed, and microswitch 13 closes in the presence of fork 39, connects Circuits System；Apply an axle to button 3 again
To downward power (or pulling out slide block to solution lock end 16 before applying power), the low degree 22 (or high plane 23) of take-up housing 4 will be led
Set 7, rotary shaft 8, the related axial downward movement together of bearing pin 9, due to the guiding helical teeth 34 of guide pin bushing 7 and the steering muscle of rotary shaft 8
37 is that tooth coordinates and be staggered half tooth, and tooth is combined with the principle of stress decomposition, when steering muscle 37 top of rotary shaft 8 depart from low tiltedly
During tooth 30 top, rotary shaft 8 rotates a certain angle automatically, fall in " W " type guiding helical teeth 34 root portion, unclamp to by
The power that key 3 applies, rotary shaft 8 is moved axially upward because of the resilience force by lifting spring 10, because the steering muscle of rotary shaft 8 is oblique
Face 36 is tooth cooperation with the inclined-plane of the low helical teeth 30 of guide pin bushing seat 6, and tooth is combined with the principle of stress decomposition, so rotary shaft 8 is automatic
Rotate a certain angle, fall in deep guide groove, now for free state, after this rotation, it is just turning to muscle 37 to rotary shaft 8
Leave well fork 39, fork 39 loses the active force to microswitch 13, microswitch 13 disconnects, Circuits System disconnects；With this
Circulation.
To sum up, the safety key switch of this drinking equipment has auto-lock function, solves existing drinking equipment press button mechanism
In pressing movement, but and it is introduced into self-locking state, the safety problem that switch has but first turned on；Also solve existing drinking-water simultaneously
Device keys mechanism button after locking is stiff, in people's life uses, brings a maloperation and damage to button
Potential problem；Technical pattern is safe and reliable, simple to operate.
The description of the aforementioned specific illustrative embodiment to the present invention illustrate that and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can much be changed
And change.The purpose of selecting and describing the exemplary embodiment is that explaining that the certain principles of the present invention and its reality should
With so that those skilled in the art be capable of and utilize the present invention various different exemplary and
Various different selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
