Abstract
The invention relates to an elastic push-and-pull limiting mechanism. A limiting block is installed on the upper surface of the back side of a base; an elastic mechanism and a movable crowbar for ejecting out the elastic mechanism are further installed on the base; three slots are formed in the base, three round holes correspondingly communicated with the slots are formed in the lateral face of the base, a spring ejection rod is installed in each round hole, an ejection block is arranged in each slot, and each spring ejection rod is connected with the corresponding ejection block through a spring; a through groove is formed in each ejection block, a connecting shaft penetrates the three through grooves, and handles are installed at the two ends of the connecting shaft respectively; the front end of the movable crowbar is horizontal, the back end of the movable crowbar cocks, and a circular arc transition structure is adopted at the position between the front end and the back end; the connecting shaft drives the ejection blocks to backwards move by backwards pulling the handles, the springs are stretched, the connecting shaft will be in contact with the circular arc transition structure of the movable crowbar so as to be ejected; and the connecting shaft is limited and positioned through the limiting block, and the ejection blocks are ejected through the movable crowbar. According to the elastic push-and-pull limiting mechanism, the lever principle is adopted for achieving the motion of controlling popup of the elastic mechanism.
Description
Technical field:
The present invention relates to position-limit mechanism apparatus field, relate 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.
Summary of the invention:
The object of the invention is for the deficiencies in the prior art part, provide a kind of elasticity push and pull construction, adopt lever principle to realize controlling the action of elastic mechanism ejection, its small volume, structure is simple.
Technology solution of the present invention 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, square connecting portion is positioned at the slotted eye position on base, and ejection part stretches out and exposes base on rear side of base.
Beneficial effect of the present invention is:
Small volume of the present invention, 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 present invention adopts lever principle to realize the action controlling elastic mechanism and 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 present invention is described further:
Fig. 1 is structural representation of the present invention;
Fig. 2 is another structural representation of the present invention;
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.
