Specific embodiment
Hereafter this utility model is described further by the drawings and specific embodiments.
With reference to Fig. 1-4, a kind of position-limit mechanism for lifting foot machine, including：Activity shackle member 1, height limit part 2, card
Latch fitting 3, unlock piece 4；
The activity shackle member 1 includes a latch 11 and the first dynamic clamping head and quiet clamping head 12；One end of the latch 11 has one
The inclined plane being engaged with the first inclined-plane 21, the second inclined-plane 22；The bottom surface of latch 11 is to be provided with a kayser in plane, and bottom surface
Groove 13.
The latch piece 3 includes a buckling piece 31 and the second dynamic clamping head and quiet clamping head 32；The buckling piece 31 has a fulcrum, card
The two ends of cramp 31 are around the spot wobble；One end of the buckling piece 31 has a buckle projection 33；The buckling piece 31 is put
When moving to horizontal level, the position of the buckle projection 33 is corresponding with latch groove 13.
The first elastic reset piece 12, the second elastic reset piece 13 are respectively torsion spring.The position-limit mechanism also includes a pair
The latch fixed plate 51,52 being oppositely arranged, two latch fixed plates 51,52 are connected by four bolts 53, four bolts 53 it
Between formed latch 11 translation passage.
The latch fixed plate 51 is provided with torsion spring fixing hole；The other end of latch 11 and buckling piece 31 also is provided with turning round respectively
Spring fixing hole.The two ends of torsion spring are respectively arranged in the torsion spring fixing hole, therefore, one end of torsion spring is fixing end, the other end with
The other end of latch 11 or buckling piece 31 is interlocked and arranged.
The height limit part 2 is gear piece, and it has multiple first oblique towards the side of latch along short transverse continuous distribution
Face 21, adjacent two the first inclined-planes 21 end to end between be connected by plane.The head end on second inclined-plane 22 be located at highest
The tail end on first inclined-plane 21 at place is connected also by plane.
The position that the unlock piece 4 is arranged is less than the horizontal plane that the first inclined-plane 21 in extreme lower position is located；The card
When the other end of cramp 31 is with 4 contact of unlock piece, the inclined plane of the latch 11 and the phase of the first inclined-plane 21 for being in extreme lower position
Mutually extrusion fit.
When the latch 11 is located at first position or the second position, the buckle projection 33 of the buckling piece 31 is from latch groove 13
It is middle disengaging and with the bottom surface contact of latch 11 so that the buckling piece 31 is rocked to non-horizontal position, and the second dynamic clamping head and quiet clamping head is squeezed
Hematocrit tires out elastic potential energy.
Above-mentioned position-limit mechanism operation principle is as follows：
The initial position of latch 11 is first position, now the inclined plane of latch 11 and one of them contact of the first inclined-plane 21
Kayser.Latch 11 is just fixed on present level.Now, if user moves down latch 11, because the bottom surface of latch 11 is put down
Face, is also plane between two the first inclined-planes 21, therefore latch 11 cannot be moved down.
If user moves up latch 11, because inclined plane and the contact of the first inclined-plane 21 coordinate the extruding force for producing to make
Obtain latch 11 to move horizontally backward, torsion spring is extruded accumulation elastic reset power.When shifting latch 11 is moved to the second position, incline
Face separates with the first inclined-plane 21, and extruding force disappears, and latch 11 is subject to the effect of elastic reset power to be reset to again from the second position
First position, and along upper first inclined-plane 21 kayser in short transverse.
When user moves up latch 11 to be moved upward to the second 22 contact of inclined-plane, due to the second inclined-plane 22 to the first
Inclined-plane 21 is grown, and so allows for the lasting level of latch 11 and retreats to the 3rd position.When latch 11 is located at three positions, latch groove
13 tops for being located at buckle projection 33, buckle projection 33 acts on lower swing in the elastic reset power of the second dynamic clamping head and quiet clamping head, so as to
So that buckle projection 33 and the kayser of latch groove 13, Jing latches 11 are fixed on the 3rd position.
When latch 11 is located at three positions, the perpendicular that its perpendicular being located is located with the first inclined-plane 21 is not sent out
It is raw to interfere, therefore latch 11 can freely drop to extreme lower position.When latch 11 drops to extreme lower position, buckling piece 31 it is another
One end and the contact of unlock piece 4, the resistance of generation so that buckling piece swings, so that buckle projection 33 takes off from latch groove
Reform into first position under the reset force effect of the first dynamic clamping head and quiet clamping head from, latch 11, with positioned at bottom that
The kayser of first inclined-plane 21.So that latch 11 is retightened in extreme lower position.Complete from low and raise again from high reduction
Circulation.
This utility model is not limited to aforesaid specific embodiment.Above-described embodiment should not be considered as limiting this practicality
New scope.Those skilled in the art can modify and become while aforementioned detailed description is read and understood
Change.Specific protection domain should be defined by claims.
