Detent mechanism
Extremely shown in Figure 9 as Fig. 1, the positioning boss 17-1 that arranges on the spring of installing between buoyancy body and the fixed body 117, positioning wire 112 and the buoyancy body constitutes the detent mechanism among the utility model one embodiment, can make buoyancy body have two settling positions (high position and low level), a unstable position (extreme lower position), the detent mechanism of similar common push switch.
As shown in Figure 6, the unsteady sleeve seat 12 of buoyancy body is provided with cylindrical hole 12-5, and location bonnet 17 is provided with reference column 17-3, and cylindrical hole 12-5 and reference column 17-3 cooperation play the guiding role mounting spring 117 in the middle of it.
As Fig. 2 and shown in Figure 7, positioning wire 112 is inserted in the mounting hole of the sleeve seat 12 that floats, steel wire is slight curving, play the elasticity location, muscle 11-2 and 11-3 with the small panel 11 of floating fastens on unsteady sleeve seat 12 above, so that positioning wire 112 and unsteady sleeve seat 12 are fixed, its location hook 112-1 is positioned at position A under the nature.
As Fig. 1, Fig. 6 and shown in Figure 7, fixed body location bonnet 17 is provided with positioning boss 17-1, and the location hook 112-1 of positioning wire 112 and positioning boss 17-1 cooperate makes buoyancy body that two stable states (high position and low level) can be arranged.
Operation principle
Continuation is with reference to Fig. 7, and in Fig. 7, the location hook of positioning wire (location hook) 112-1 does not show that wherein the small circle in each state is represented the position of location hook previous state.Under the reset condition, the clutch detent mechanism is in state 1, the location hook of positioning wire 112 is in position A, the out of nature extension state of positioning wire, its natural bearing of trend is shown in the dotted line that is in vertical direction among Fig. 7, in other embodiment of the present utility model, positioning wire also can replace with other forms of thin elastic rod, positioning wire or thin elastic rod be linear preferably, but also can be slight curving or other shapes, the natural bearing of trend of positioning wire or thin elastic rod is the bearing of trend under its nature, and as shown in Figure 7, its natural bearing of trend is vertical direction.Buoyancy body moves upward under the spring force effect, push up on the socket loam cake 16 of fixed body up to a boss 12-6 of buoyancy body, this moment, buoyancy body was in a stable high position, shell fragment 114,115,19 silver contact are connected copper bar 122,121,113 not contact of silver contact with power supply, all sleeves 13,15 and power supply do not have and be electrically connected, as shown in Figure 3.
The insertion plug also presses down, the elastic force that plug and buoyancy body overcome spring 117 moves down, up to the H+h stroke, detent mechanism is in state 2, under the guide effect of the guiding surface 710 of positioning boss 17-1, the location hook of positioning wire 112 is in position B, and this moment, buoyancy body was in unstable position, saw state shown in Figure 72.Guiding surface 710 is that the natural bearing of trend of relative positioning steel wire 112 is to lopsidedness, therefore the location hook of positioning wire 12 is in the process that guiding surface 710 slides, positioning wire 112 is slightly elastic bending, positioning wire 112 is offset to the right with respect to its natural bearing of trend in the state 2 shown in Figure 7, therefore positioning wire 112 will have the trend of elastic reset to the left, near a side 740 of boss, the movement locus of location hook is shown in 713.
Simultaneously with reference to Fig. 1, the state 3 of Fig. 5 and Fig. 7, unclamp downforce, buoyancy body is upward stroke h under the power effect of spring 117, detent mechanism is in state 3, at this moment, the location hook of positioning wire 112 slips over guiding surface 710 fully, because positioning wire 112 has the trend of elastic reset to the left, therefore buoyancy body is in the process that rises, the location hook of positioning wire has resilience campaign left simultaneously, therefore enter into the recess 711 of positioning boss 7-1, therefore be in position C, this moment, buoyancy body was in stable low level, shell fragment 114,115,19 silver contact is connected copper bar 122 with power supply, 121,113 silver contact contact, sleeve 13 floats, 15 and power supply realize being electrically connected.Enter into the process of recess 711 at location hook, location hook preferably stops by the straight wall 740 of stop part 17-4, avoids the positioning wire resilience too fast and miss recess 711, and the movement locus of location hook is shown in 714.
State 4 with reference to Fig. 7, press buoyancy body again, apply stroke h, because recess 711 departs from the natural bearing of trend of positioning wire equally, therefore positioning wire has equally to the trend that resilience is arranged before breaking away from recess 711, in case downward stroke h is arranged, skew wall 741 by means of stop part 17-4, detent mechanism just is in state 4, the location hook of positioning wire is in position D, and positioning wire is returned to the nature extension state, because location hook breaks away from recess, this moment, buoyancy body was in unstable position, and the movement locus of location hook is shown in 715.
Unclamp downforce again, buoyancy body is upward stroke H+h under the power effect of spring 117, and positioning wire 112 will be with buoyancy body upward stroke H+h, in uphill process, can be by means of the guiding on the inclined-plane 712 of positioning boss 17-1, along sliding back to the position, detent mechanism is in state 5, the location hook of positioning wire is in position A, the movement locus of location hook is shown in 716, and this moment, buoyancy body was in a stable high position again, and all sleeves and power supply do not have and be electrically connected, get back to reset condition, see Fig. 7 state 5.
In the aforesaid operations process, the location hook 112-1 of positioning wire is around the positioning boss 17-1 motion that goes round and begins again.
Second embodiment
In second embodiment of the present utility model, the boss of detent mechanism and the positioning wire location swap on fixed body and buoyancy body, the electric connecting mode of the L utmost point, the N utmost point and earth polar sleeve and power supply conductivity body are connected by spring-piece type and are changed to insert-type and connect.
