On the equipment of unidirectional locking arrangement of the present utility model applicable to this unidirectional locking function of any needs, be particularly useful for a kind of chucking device.
The utility model preferably provides a kind of mobile phone grip slipper that comprises above-mentioned unidirectional locking arrangement, shown in Fig. 6-9, comprising: upper clipping claw 1, following claw 2, bonnet 4, knob 5, slide block 6, cam swing 7, cam spring 8, stopping means 9, Damping rotation shaft 10, locked rotor 11, cartridge type damping 12, gear 13, wind spring 14, wind spring axle 15, screw 16.Wherein, following claw 2 is installed in the chute 1.1 of upper clipping claw 1 and can slides up and down along chute 1.1, and tooth bar 2.1 is located at down a side of claw 2, and extends to its rear side from the outside of upper clipping claw 1, is meshed with gear 13, and described tooth bar 2.1 is parallel with described chute 1.1.Damping rotation shaft 10 passes the locked rotor 11 on cartridge type damping 12, gear 13 and the cartridge type damping outer wall successively, and two axis holes that two ends are against respectively on upper clipping claw 1 and the bonnet 4 are interior fixing, and bonnet 4 is fixing by screw 16 with upper clipping claw 1.Wind spring 14 is placed on the wind spring axle 15, and is assemblied in together in the semiaxis hole 1.5 on the upper clipping claw 1, and the hanging hole 14.1 on the wind spring 14 passes on the wind spring hook 2.2 that hangs over down behind the wind spring hole 1.3 on the upper clipping claw 1 on the claw 2.Worm screw 5.1 passes the top of upper clipping claw and installs, and the lower end is connected with slide block 6, cam swing 7 successively, and the lower end of cam swing 7 connects cam spring 8, and the lower end of cam spring 8 is against on the baffle plate 1.4 of upper clipping claw 1.
According to a preferred embodiment of the present utility model, cam swing 7 also comprises the mounting blocks 7.4 perpendicular with swing arm 7.5, and described mounting blocks 7.4 is installed in the mounting groove 1.2 of described upper clipping claw 1.
According to a preferred embodiment of the present utility model, have weakened region 7.2 between described mounting blocks 7.4 and the swing arm 7.5, allow swing arm 7.5 to swing up and down.When knob 5 rotated to released state, swing arm 7.5 can be with respect to mounting blocks 7.4 to lower swing, otherwise when knob 5 rotate to lockup state, swing arm 7.5 was upwards swung.When knob 5 went to release or lockup state, swing arm 7.5 restored to the original state.
Preferably, the clamping face on described upper clipping claw 1 and the described claw 2 down is equipped with the flexible glue pad.This flexible glue pad moves for clamping movement and has nothing to do, and just in order to increase some frictional force, guarantees higher fail safe.
Shown in Figure 10-15, the operation principle of mobile phone grip slipper of the present utility model is as follows:
As Figure 10-11 and shown in Figure 14, when knob 5 rotated to released state, slide block 6 was moved downward to extreme lower position, and related stopping means 9 is moved downward to lowest order.As shown in figure 10, tooth bar 2.1 on the following claw 2 is meshed with gear 13, when the user spurs down claw 2 to lower slider, tooth bar 2.1 driven gears 13 are rotated counterclockwise, then driving locked rotor 11 is rotated counterclockwise, prop up the last disc of the slotted hole 9.2 on the stopping means 9 up to the boss 11.4 on the locked rotor 11, locked rotor 11 maintains static, and the upper and lower latch 11.3 and 11.2 on this moment locked rotor 11 all breaks away from tooth bar.Tooth bar 2.1 is subjected to the effect of user's pulling force can continue to move down, and gear 13 continues to rotate under the effect of tooth bar 2.1.The user can regulate down claw as required and move down distance.
As shown in figure 11, after the user loosed one's grip, following claw 2 was moved upward by the pulling force driving of wind spring 14, and tooth bar 2.1 driven gears 13 turn clockwise, and drive locked rotor 11 then and turn clockwise.The last disc of the slotted hole 9.2 on the 11.4 disengaging stopping means 9 of the boss on the locked rotor 11 moves downward at this moment, and the following latch 11.2 of locked rotor 11 snaps in tooth bar 2.1, and tooth bar is by locked, and following claw rests on the position that the user looses one's grip.
That is to say that under released state, this time claw can be to lower slider under user's external force, this direction to lower slider is the permission direction of motion; In case external force disappears, following claw is reverse, and locked rotor is rotated, and tooth bar is locked, and following claw can't up slide, and the direction that should upwards slide is the locking direction.At this moment, the direction that the following claw of this mobile phone seat up slides is realized unidirectional locking by locked.
As Figure 12-13 and shown in Figure 15, the knob 5 that will be in released state is the Rotate 180 degree backward, and knob 5 is in the lock state, and slide block 6 is moved upward to the extreme higher position, and related stopping means 9 is moved upward to highest order.Instantly claw 2 is driven when moving upward by the pulling force of wind spring 14, and tooth bar 2.1 driven gears 13 turn clockwise, and drive locked rotor 11 then and turn clockwise.Prop up the following disc of the slotted hole 9.2 on the stopping means 9 up to the boss 11.4 on the locked rotor 11, locked rotor 11 maintains static, and the upper and lower latch 11.3 and 11.2 on this moment locked rotor 11 all breaks away from tooth bar.Tooth bar 2.1 is subjected to wind spring 14 pulling force effects can continue to move up, and gear 13 continue to rotate under the effect of tooth bar 2.1, and following claw 2 can continue to move upward up to clamping navigator or reaching the minimum stroke of design.
As shown in figure 13, claw 2 is impacted or misoperation when moving downward instantly, and tooth bar 2.1 driven gears 13 are rotated counterclockwise, and drive locked rotor 11 then and are rotated counterclockwise.The following disc that the boss 11.4 of locked rotor 11 breaks away from the slotted hole 9.2 of stopping means 9 moves upward.This moment, the last latch 11.2 of locked rotor 11 snapped in tooth bar 2.1, and following claw is by locked, had guaranteed that mobile phone navigates impacted or can not come off during misoperation.
That is to say that under lock-out state, this time claw upwards slides under the pulling force effect of spool, the direction that should upwards slide is for allowing the direction of motion; In case claw is subjected to downward impact down, locked rotor is rotated, and tooth bar is locked, and following claw can't be toward lower slider, and this direction to lower slider is the locking direction.At this moment, the direction of the past lower slider of the following claw of this mobile phone seat is realized unidirectional locking by locked.Guarantee the safety of mobile phone or navigator.
Above-described, be preferred embodiment of the present utility model only, be not in order to limiting scope of the present utility model, above-described embodiment of the present utility model can also make a variety of changes.Be that simple, the equivalence that every claims according to the utility model application and description are done changes and modification, all fall into the claim protection range of the utility model patent.The utility model not detailed description be the routine techniques content.
