Description
Technical field:
The utility model relates to position-limit mechanism apparatus field, relates to a kind of elasticity push and pull construction adopting lever principle to realize the action controlling elastic mechanism ejection in particular.
Background technology:
Existing push-pull mechanism is all generally that air cylinder driven push rod realizes ejecting of pushing block and resets, its equipment is large, and structure is more complicated all, all adopts drive unit, add production cost, at some special occasions, due to limited space, this push-pull mechanism can not be applied, therefore be necessary to design a kind of volume little, do not use drive unit, only adopt simple frame for movement just can realize the mechanism of push-and-pull, meet more demands of people.
Utility model content:
The purpose of this utility model is for the deficiencies in the prior art part, provides a kind of elasticity push and pull construction, and adopt lever principle to realize controlling the action of elastic mechanism ejection, its small volume, structure is simple.
Technology solution of the present utility model is as follows:
A kind of elasticity push and pull construction, comprise base, on the rear side upper surface of described base, two ends, left and right are separately installed with one group of limited block; The movable crow bar described base being also provided with elastic mechanism and elastic mechanism is ejected; Described elastic mechanism comprises spring spindle, jacking block, spring, connecting axle and handle, described base is provided with three slotted eyes, base side is provided with three circular holes be connected with corresponding slotted eye, circular hole is built with spring spindle, be provided with one group of jacking block in each slotted eye, often organize between spring spindle and corresponding jacking block and linked together by spring; Described jacking block is provided with and runs through groove, and described connecting axle runs through groove through three groups, and the two ends of connecting axle are separately installed with handle; The front end level of described movable crow bar, rear end tilts, and adopts arc transition structure between the front end of movable crow bar to rear end; Described connecting axle is driven after jacking block by handle post-tensioning and moves, and makes spring elongation, and connecting axle can contact the arc transition structure of movable crow bar and by jack-up, and connecting axle limits location by limited block a and limited block b, makes jacking block be controlled to eject by movable crow bar.
As preferably, described handle comprises two groups of semicircular ring, and two groups of semicircular ring by screw locking on connecting axle.
As preferably, described movable crow bar has two groups, two groups of activity crow bar front ends by briquetting and bolt-locking on base.
As preferably, the often group in described two groups of activity crow bars is located at interval between three groups of jacking blocks respectively.
As preferably, the integral structure that described jacking block is made up of square connecting portion and ejection part, the slotted eye position of square connecting portion on base, ejection part stretches out and exposes base on rear side of base.
The beneficial effects of the utility model are:
The utility model small volume, structure is simple, move after connecting axle posterior tension bands dynamic elasticity mechanism during work, spacing by limited block after elastic mechanism to allocation, when connecting axle moves backward by the radian characteristic of movable crow bar by movable crow bar jack-up, realize elastic mechanism and eject and control to eject by movable crow bar.The action that the utility model adopts lever principle to realize controlling elastic mechanism to eject, and jacking block ejects and resets and has pooling feature under the action of the spring, prevents the ejecting excessive velocities of jacking block and the hard impact that produces.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another structural representation of the present utility model;
Fig. 3 is the top view of Fig. 1.
Detailed description of the invention:
Embodiment, is shown in accompanying drawing 1 ~ 3, and a kind of elasticity push and pull construction, comprises base 1, and on the rear side upper surface of described base, two ends, left and right are separately installed with one group of limited block, is limited block a2 and limited block b3; The movable crow bar 4 described base being also provided with elastic mechanism and elastic mechanism is ejected; Described elastic mechanism comprises spring spindle 5, jacking block 6, spring 7, connecting axle 8 and handle 9, described base is provided with three slotted eyes 10, base side is provided with three circular holes be connected with corresponding slotted eye, circular hole is built with spring spindle, be provided with one group of jacking block in each slotted eye, often organize between spring spindle and corresponding jacking block and linked together by spring; Described jacking block is provided with and runs through groove 11, and described connecting axle runs through groove through three groups, and the two ends of connecting axle are separately installed with handle; The front end level of described movable crow bar, rear end tilts, and adopts arc transition structure 12 between the front end of movable crow bar to rear end; Described connecting axle is driven after jacking block by handle post-tensioning and moves, and makes spring elongation, and connecting axle can contact the arc transition structure of movable crow bar and by jack-up, and connecting axle limits location by limited block a and limited block b, makes jacking block be controlled to eject by movable crow bar.
Described handle comprises two groups of semicircular ring, and two groups of semicircular ring by screw locking on connecting axle.
Described movable crow bar has two groups, two groups of activity crow bar front ends by briquetting 13 and bolt-locking on base.
