Abstract
The invention discloses a steel ball lifting mechanism which comprises a bottom plate and a movable block, wherein the bottom plate is matched with the movable block by a guide rod and a guide hole for liftable sliding; a groove is arranged at one side of the upper surface of the bottom plate; an outer opening of the groove is articulated with an L-shaped swing block by a rotating shaft; the L-shaped swing block comprises a swing arm and a swing foot which is matched with the groove; the swing arm is provided with a nick and an elastic jacking mechanism; the width of the nick is approximately equal to the thickness of the movable block, and the nick is buckled with the movable block in a matching way; and an ejection part of the elastic jacking mechanism is positioned at one side of the nick far away from the bottom plate. The steel ball compression lifting mechanism disclosed by the invention can realize the functions of stably self-locking after rising and compressing after descending, is simple in structure and fewer in parts, does not need electrical equipment and is completely formed by mechanical parts, thus being suitable for occasions with shorter lifting distance (less than 50mm) and lower pressing force. Furthermore, the steel ball lifting mechanism is convenient to operate, and all the lifting and compressing actions can be finished by moving the L-shaped swing block, so that the steel ball lifting mechanism has popularization value and strong universality.
Description
technical field:
The present invention relates to a kind of lifting mechanism.
background technology:
Self-locking is stablized in existing requirement after rising, the lifting mechanism that can compress again after declining adopts cylinder to control mostly, and the problem that has complex structure, operation inconvenience and need to safeguard, also needs proportioning to control electric, causes cost higher.
summary of the invention:
The present invention is directed to the problem and shortage that prior art exists, a kind of lifting mechanism is provided.
The technical solution adopted in the present invention: a kind of lifting mechanism, comprise base plate and movable block, by pilot bar and pilot hole, coordinate liftable to slide between the two, wherein a side of plate upper surface is provided with groove, the collar extension place of groove is hinged with a L shaped centering block by rotating shaft, this L shaped centering block comprises a swing arm and pendulum pin, pendulum pin mates with groove, in swing arm, be provided with breach and elasticity jacking mechanism, the width of this breach is approximately equal with the thickness of movable block and mate fastening, elasticity jacking mechanism eject the side that part is positioned at breach.
Described elasticity jacking mechanism is that the swing arm end at L shaped centering block arranges inner chamber, in inner chamber, from indentation, there, steel ball, spring and puller bolt is outwards installed successively, and it is porose that inner chamber is positioned at breach one side, and the diameter in this hole is less than steel ball size.
Between steel ball and spring, be also provided with pad.
Base plate upside is fixed with two pilot bars straight up, is respectively arranged with the pilot hole of coupling on sliding shoe, and slide block is sleeved on two pilot bars and is realized bearing fit by its pilot hole.
The pendulum pin upper side edge of L shaped centering block is arc transition.
Breach arris near steel ball one side is set to chamfering structure.
Good effect:
1, steel ball compression type lifting mechanism of the present invention can keep stable after can realizing and rising under the support of steel ball, the function that can compress again after declining, it is simple in structure, number of components is few, do not need electrical equipment, and formed by mechanism's part completely, be applicable to lifting distance little (being less than 50mm), and the not high occasion of thrust.
2, easy to operate, all liftings and compression only need to be moved L centering block, have promotional value, highly versatile.
accompanying drawing explanation:
Fig. 1 is perspective view of the present invention;
Fig. 2 is jack-up view of the present invention;
Fig. 3 is the present invention's view that declines.
Number in the figure 1 is base plate, and 2 is movable block, and 3 is L shaped centering block, and 4 is steel ball, and 5 is spring, and 6 is rotating shaft, and 7 is pilot bar, 8 breach, and 9 is groove, and 10 for screwing bolt, and 11 is pad, and 12 is elasticity jacking mechanism.
the specific embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, this lifting mechanism comprises base plate 1 and movable block 2, is fixed with two pilot bars of establishing 7 on base plate 1, is provided with the pilot hole (not label) of two couplings on movable block 2, the pilot hole of movable block 2 is sleeved on pilot bar 7, thereby can lifting slide between the two.One side of base plate 1 upper surface is provided with groove 9, and the collar extension place of groove 9 is horizontally installed with a rotating shaft 6, and the corner of L shaped centering block 3 is provided with axis hole (not label), axis hole and rotating shaft 6 Matching installations.Turning one side of described L shaped centering block 3 is that swing arm, opposite side are pendulum pin, and wherein putting pin mates with groove 9, and L shaped centering block 3 can be produced and be swung by rotating shaft 6.In swing arm, be provided with breach 8 and elasticity jacking mechanism 12, the width of this breach 8 equates and mates fastening with the thickness of movable block 2.As Fig. 2, when L shaped centering block 3 rotates clockwise after 90 degree, the lower surface of pendulum pin jack-up movable block 2, now movable block 2 is along pilot bar 7 upwards translations, the jack-up face A rounding off of pendulum pin.Described elasticity jacking mechanism 12 is the swing arm ends at L shaped centering block 3, elasticity jacking mechanism 12 arranges inner chamber, in inner chamber, from indentation, there, steel ball 4, pad 11, spring 5 and puller bolt 10 are outwards installed successively, inner chamber is provided with hole near a side of breach 8, the diameter in this hole is less than steel ball 4 diameters, thereby steel ball 4 has part to expose this hole.Referring to Fig. 3, when L shaped centering block 3 left-hand revolutions 90 are spent, breach 8 is fastened on movable block 2 one sides just, and steel ball 4 tops are pressed on movable block 2 upper surfaces and form and hold out against the B of portion, and when rotated, movable block 2 is along the downward translation of guide rod 7 for L shaped centering block 3.
