Embodiment
For example the present invention is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1~5, whole push-pull chain chief component has: outer plate 1, spring clip 2, inner plate 3, spring bolt 4, bearing pin 5, sleeve 6, roller 7, spring 8, push-and-pull piece 9, sprocket wheel 10, transmission shaft 11, chain cover 12.
In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a chain part is in chain cover 12 the insides, and a part is in chain cover 12 outsides.Because the outer plate 1 of chain and inner plate 3 adopt special circular-arcly, the high spot of next joint outer plate 1 and inner plate 3 is just in time embedded in a recess that saves outer plate 1 and inner plate 3, so the chain in chain cover 12 can only bend in one direction.A spring locking mechanism has been added in bearing pin 5 the insides of chain, namely beat a circular hole in bearing pin 5 inside, a spring 8 has been installed in the inside, the spring bolt 4 that has done in addition a special shape is connected with spring 8, spring bolt 4 has upper and lower two bearing pins, align with bearing pin 5 in the bearing pin center, top of spring bolt 4, bottom and outer plate 1 and inner plate 3 center of circular hole below align.Chain is in chain cover time, and because chain cover 12 has squeezing action to the top of spring bolt 4, spring 8 is compressed, and spring bolt 4 is pressed into the inside, and the pin of bottom does not enter into outer plate 1, so do not lock.When chain out time, owing to having lost the squeezing action of chain cover 12 to spring bolt 4 top bearing pins, ejects spring bolt 4 from chain cover 12 under the effect of spring 8 restoring forces, spring bolt 4 bottom bearing pins are inserted in outer plate 1 and go, make chain by locked can not be bending.When chain promotion object straight line travels forward, motor forward, utilizes transmission shaft 11 to be with movable sprocket 10 to rotate, and chain can utilize push-and-pull piece 9 to promote object straight line motion forward under the drive of sprocket wheel 10.Chain is in the time drawing object, motor reversal drives transmission shaft 11 to rotate backward, thereby make chain reversing motion, chain is entering 12 moments of chain cover because spring bolt 4 top bearing pins are from being newly subject to the extruding of chain cover 12, make bottom divide bearing pin to release 1 li of outer plate, chain can bend in one direction, thereby can make chain be recovered to chain cover 12 inside.
A part for sprocket wheel and chain is in chain cover, and another part is in chain cover outside.The carrier bar of chain adopts special arcuation, and the projection of upper shot of a cable plate is just in time embedded in the recess of lower shot of a cable plate, and therefore chain is only with bend in one direction.The bearing pin the inside of chain has added a spring locking mechanism, chain in chain cover the inside because chain cover side opens locking mechanism to the extruding of spring bolt.In the time that chain promotion object straight line is proal, motor forward drives sprocket rotation, sprocket wheel drives chain movement, every shot of a cable is from chain cover moment out, owing to having lost the extruding force of chain cover side to it, so spring bolt is inserted in carrier bar under the effect of spring restoring force, make it by locked can not be bending, having realized can not be bending at the chain of chain cover outside, can only straight line motion.In the time that chain draws object to move backward, the reversion of driven by motor sprocket wheel, thus drive chain movement, when chain enters chain cover moment, spring bolt is extruded into, and locking mechanism is opened, thus chain can be realized bend in one direction.
Chain of the present invention can bend in one direction in chain cover, when chain link from chain cover out time winding machine become born of the same parents, make chain both sides all can not bending can only be along straight line motion, thereby the object straight line that can promote above travels forward, in the time that chain is got back to chain cover, chain link can bend in one direction.
Carrier bar adopts special shape, makes the chain can only bend in one direction in chain cover inside.
There is a locking mechanism bearing pin the inside of chain, when chain is from chain cover moment out, makes it by locked, can not be bending; When the moment that chain is got back to chain cover, locking mechanism is opened, thereby makes the chain again can bend in one direction.
Carrier bar adopts special arcuation, and the carrier bar projection of next chain link is just in time embedded in the recess of shot of a cable plate.
The inner spring locking mechanism that adopts of chain bearing pin, chain moment out in chain cover, under the effect of spring force, spring bolt inserts inner plate and outer plate, by its locked can not be bending.When the moment that chain is got back to chain cover, spring bolt is pushed the inside by chain cover, makes its locked being opened, again bend in one direction.
Spring locking mechanism is made up of spring and spring bolt, and spring bolt adopts special construction, point upper lower bearing pin two-part, and top distribution shaft centre line aligns with the bearing pin center line of chain, and the following circle hole centreline of lower part and carrier bar aligns.
