3rd step: be fixed on the pedestal 12 of lock set by sensitive switch 13 with long spiro nail 14, requires that the fork 39 of sensitive switch 13 contacts with the muscle 37 that turns to of rotating shaft 8 inwardly;
4th step: button guide pillar 20 will be penetrated by key spring 5, and by button assembly be assembled together from the guide pin bushing seat 6 of lock set.
Operation principle of the present invention: first, stir the unblock end 16 of slide block 2 to slide block slot 15, take-up housing 4 moves thereupon together, then, the downward power of an axis is applied to button 3, the high plane 23 of take-up housing 3 is by guide pin bushing 7, rotating shaft 8, the related axial downward movement together of bearing pin 9, because the guiding helical teeth 34 of guide pin bushing 7 is that tooth coordinates and the half tooth that is staggered with the muscle inclined-plane 36 that turns to of rotating shaft 8, tooth is combined with the principle of stressed decomposition, when rotating shaft 8 turn to muscle 37 top to depart from high helical teeth 31 top time, the angle that rotating shaft 8 automatic rotation is certain, fall into the tooth root portion of the guiding helical teeth 34 in " W " type, unclamp the power applied to button 3, rotating shaft 8 is because being subject to lifting spring 10 resilience force, axially move upward, again because the muscle inclined-plane 36 that turns to of rotating shaft 8 is that tooth coordinates with high helical teeth 31 inclined-plane of guide pin bushing seat 6, tooth is combined with the principle of stressed decomposition, the angle that rotating shaft 8 automatic rotation is certain, fall into the tooth root portion of high helical teeth 31, it is now self-locking state, rotating shaft 8 is after the angle rotation of twice, it turns to muscle 37 just in time to be depressed by fork 39, sensitive switch 13 is closed under the effect of fork 39, connect Circuits System, again apply the downward power (or being pulled out by slide block before applying power to unblock end 16) of an axis to button 3, the low degree 22 (or high plane 23) of take-up housing 4 is by guide pin bushing 7, rotating shaft 8, the related axial downward movement together of bearing pin 9, because the guiding helical teeth 34 of guide pin bushing 7 is that tooth coordinates and the half tooth that is staggered with the muscle 37 that turns to of rotating shaft 8, tooth is combined with the principle of stressed decomposition, when rotating shaft 8 turn to muscle 37 top to depart from low helical teeth 30 top time, the angle that rotating shaft 8 automatic rotation is certain, fall into the tooth root portion of the guiding helical teeth 34 in " W " type, unclamp the power applied to button 3, rotating shaft 8 axially moves upward because of the resilience force being subject to lifting spring 10, because the muscle inclined-plane 36 that turns to of rotating shaft 8 is that tooth coordinates with the inclined-plane of the low helical teeth 30 of guide pin bushing seat 6, tooth is combined with the principle of stressed decomposition, so the angle that rotating shaft 8 automatic rotation is certain, fall in dark guide groove, it is now free state, rotating shaft 8 is after this rotates, it turns to muscle 37 just in time to leave fork 39, fork 39 loses the active force to sensitive switch 13, sensitive switch 13 disconnects, Circuits System disconnects, circulate with this.
To sum up, the safety key switch of this drinking equipment has auto-lock function, solves existing drinking equipment press button mechanism when pressing movement, but does not enter self-locking state, the safety problem of switch but first conducting; Also solve existing drinking equipment press button mechanism button after locking stiff simultaneously, live in use people, bring the potential problem of a misoperation and damage to button; Technical pattern is safe and reliable, simple to operate.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
