Description
Technical field
The present invention relates to the mechanical motion mechanism technical field realizing intermittent movement direction-agile, particularly the two-way intermittent motion mechanism of one.
Background technique
At present, known intermittent motion mechanism, is made up of driving pawl, rocking bar, non-return ratchet, ratchet etc.During institution staff, rocking bar reciprocally swinging, drives ratchet can promote ratchet and does intermittent movement.When rocking bar backhaul swings, owing to being subject to the non-return effect of check pawl, ratchet can not take a turn for the worse.This mechanism just ensure that the one-way intermittent motion of ratchet.But the intermittent movement direction of this mechanism is non-adjustable, the intermittent movement in some directions can only be carried out.Actual production and life need the occasion of reversible intermittent movement in applying, this mechanism then cannot satisfy the demands.
Summary of the invention
Goal of the invention of the present invention is for the existing technical deficiency realizing the mechanical motion mechanism of intermittent movement direction-agile, provides a kind of two-way intermittent motion mechanism.
For achieving the above object, the technical solution used in the present invention is:

Preferably, described body also comprises the first housing and second housing two-part, controls hand lever and also comprises elasticity positioning pawl; Control hand lever to be positioned by the shaft shoulder of elasticity positioning pawl and body.
Preferably, described elasticity positioning pawl is provided with locator protrusions, and the shaft shoulder of described body is provided with the positioning groove matched with locator protrusions.
Preferably, described first ratchet group comprises the first ratchet and the second ratchet that cooperatively interact, and the second ratchet is provided with the first holddown spring.
Preferably, described second ratchet group comprises the 3rd ratchet and the 4th ratchet that cooperatively interact, and the 4th ratchet is provided with the second holddown spring.
Preferably, control hand lever to be connected with the 3rd ratchet by bolt.
Preferably, described boss is yi word pattern boss, and described groove is yi word pattern groove.
Moving direction controlled by controlling hand lever.Be provided with two groups of ratchets in body, be designated as respectively and put the first ratchet, the second ratchet, the 3rd ratchet and the 4th ratchet.Control hand lever to be positioned by elasticity positioning pawl and the body shaft shoulder, and be connected by the driving ratchet of bolt with second ratchet group.Control hand lever end and be provided with two yi word pattern projections.
When control hand lever is in relaxed state, under the effect of the first holddown spring 1, the second ratchet 2 compresses to the first ratchet, and the two is in engagement; And owing to controlling hand lever without active force, the 3rd ratchet departs from the 4th ratchet under the drive controlling hand lever, the two is in non-engagement state; Whole mechanism can carry out forward intermittent movement.
When External Force Acting is in time controlling hand lever, control hand lever is pressed downward to half-twist after the end of the yi word pattern groove of body, the yi word pattern boss controlled on hand lever is subject to the plane restriction of yi word pattern groove end face and locates, control hand lever and be in impaction state, now the second ratchet to depart from the first ratchet and engages under the drive controlling hand lever, and the 3rd ratchet engages each other with the 4th ratchet under hand lever effect; Whole mechanism can carry out reverse intermittent movement.To control hand lever counter-rotating 90 °, then return relaxed state by yi word pattern groove, the 3rd ratchet and the 4th ratchet depart from and to engage and the first ratchet and the second ratchet recover to engage, and positive engagement is recovered by whole mechanism.
The present invention, relative to prior art, has following beneficial effect:
In order to meet the demand of actual production life to the direction-agile of intermittent motion mechanism, the invention provides a kind of two-way intermittent motion mechanism, this mechanism can not only be stable the unidirectional intermittent movement carrying out some directions, but also change the direction of intermittent movement by shirtsleeve operation.Be provided with two groups of ratchets in body of the present invention, control hand lever and positioned by elasticity positioning pawl and the body shaft shoulder, and be connected by the driving ratchet of bolt with second ratchet group.Hand lever end has two yi word pattern boss.When hand lever is in relaxed state, under the effect of the first holddown spring, first group of ratchet is in engagement, and mutually departs between second group of ratchet and be in non-engagement state, and whole mechanism can carry out forward intermittent movement.External Force Acting is in control hand lever, control hand lever is pressed downward to half-twist after the end of the yi word pattern groove of body, the yi word pattern boss controlled on hand lever is subject to the plane restriction of groove end face and locates, now first group of ratchet departs from, second group of ratchet under the effect of control hand lever engages each other, and whole mechanism can carry out reverse intermittent movement.Need the occasion of the moving direction changing intermittent movement in actual production life under, mechanism can control varying motion direction easily.
