The specific embodiment
As shown in Figure 1, the push button release mechanism of the present embodiment is mainly used in dust catcher, and it comprises latch segment 1 and latch segment support 2.
Described latch segment 1 comprises body 11, and this body is provided with left the locking part 12 that extends, the press section 13 of extending to the right and to the connecting portion 14 of downward-extension.The lower end of described connecting portion 14 is hinged on described latch segment support 2 by rotating shaft 16, and when being connected with spring 6(assembling on connecting portion 14, the other end of spring is against on dust catcher body), this spring 6 applies left thrust to connecting portion.13 tops, described press section are provided with the button 5 that can press down this press section.
Described latch segment support 2 is provided with vertical gathering sill 21, is furnished with the slide block 22 that can slide up and down in this gathering sill 21 within it, and is provided with stage clip 27(stage clip 27 between gathering sill 21 upper ends and slide block 22 and applies downward pressure to slide block 22).The top of slide block 22 is connected with the elastic spacing arm 23 of a U font, and this elastic spacing arm 23 stretches out outside gathering sill 21 and is positioned at the below of described locking part 12.The bottom of slide block 22 be connected with one that extend left and stretch out the outer raised line 24 of gathering sill 21, be connected with dismountable link 4 between this raised line 24 and described locking part 12.
In the present embodiment, the concrete annexation that described link 4 and raised line 24 and locking part are 12 is as follows: link 4 be provided with up the first snap-latch surface 41 and the second snap-latch surface 42 down, and the first snap-latch surface 41 is positioned at the below of the second snap-latch surface 42, and described raised line 24 and locking part 12 are stuck on the first snap-latch surface 41 and the second snap-latch surface 42.
Being provided with a rotating swing pinion 3(swing pinion between described locking part 12 and elastic spacing arm 23 is arranged on dust catcher body by wheel shaft is rotating), be shaped with the first double wedge 15 that is meshed with described swing pinion 3 on locking part 12, be shaped with the second double wedge 25 that is meshed with described swing pinion 3 on elastic spacing arm 23.
Excessive to left movement under the elastic force effect of spring 6 for fear of latch segment 1, this example is provided with the first positive stop strip 17 to downward-extension on described locking part 12, be provided with upwardly extending the second positive stop strip 26 on described latch segment support 2, described the first positive stop strip 17 is against the right side of the second positive stop strip 26.
With reference to Fig. 1 ~ shown in Figure 4, existing operation principle with this push button release mechanism is described below:
As Fig. 1, under original state, latch segment 1 and elastic spacing arm 23 all are in engagement with swing pinion 3, and the first positive stop strip 17 is against on the second positive stop strip 26, and swing pinion 3 can not freely rotate, and latch segment 1 is locked together corresponding component, is in locking state.
As Fig. 2, press the button 5, button 5 presses down latch segment 1 and it is clockwise rotated and break away from link 4, and in the process that latch segment 1 rotates, because spring position limit arm 23 has elasticity, swing pinion 1 also can rotate.
As Fig. 3, release button 5, move on button 5 with latch segment 1 and break away from, because the second double wedge 25 on position limit arm 23 is being stung link swing pinion 3(this moment position and is not being changed, the raised line of slider bottom is appointed on the first snap-latch surface that so is stuck in link), make the latch segment 1 can not spinning reduction, realize release between described corresponding component, be in released state.
As Fig. 4, remove link 4, slide block 22 is in free state, under the elastic force effect of stage clip 27, and slide block 22 down slidings, drive elastic spacing arm 23 moves down together the second double wedge 25 that makes on the elastic spacing arm and is separated with swing pinion 3, swing pinion 3 loses the restriction of the second double wedge 25, and latch segment 1 resets under the effect of spring 6, and the first positive stop strip 17 is against on the second positive stop strip 26, get back to initial position, be in again locking state.
Certainly, above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow people can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the Spirit Essence of the utility model main technical schemes are within all should being encompassed in protection domain of the present utility model.
