When the control hand lever was in relaxed state, under the effect of first holddown spring 1, second ratchet 2 compressed to first ratchet, and the two is in engagement; And because the control hand lever does not have active force, the 3rd ratchet breaks away from the 4th ratchet under the drive of control hand lever, and the two is in non-engagement state; Entire mechanism can be carried out the forward intermittent movement.
When external force acts on the control hand lever, the control hand lever is pressed downward to the terminal back half-twist of the yi word pattern groove of body, yi word pattern boss on the control hand lever is subjected to the plane restriction of yi word pattern groove end face and locatees, the control hand lever is in impaction state, this moment, second ratchet broke away from engagement with first ratchet under the drive of control hand lever, and the 3rd ratchet is meshing with each other with the 4th ratchet under the hand lever effect; Entire mechanism can be carried out reverse intermittent movement.To control 90 ° of hand lever counter-rotatings, and then can return relaxed state by the yi word pattern groove, the 3rd ratchet and the 4th ratchet break away from engagement and first ratchet and second ratchet recovery engagement, and entire mechanism is recovered positive engagement.
The utility model has following beneficial effect with respect to prior art:
In order to satisfy the actual production life to the demand of the direction-agile of intermittent motion mechanism, the utility model provides a kind of two-way intermittent motion mechanism, this mechanism can not only be stable the unidirectional intermittent movement of carrying out some directions, and can also change the direction of intermittent movement by shirtsleeve operation.Be provided with two groups of ratchets in the body of the present utility model, the control hand lever positions by elasticity positioning pawl and the body shaft shoulder, and links to each other by the driving ratchet of bolt with second ratchet group.The hand lever end has two yi word pattern boss.When hand lever was in relaxed state, under the effect of first holddown spring, first group of ratchet was in engagement, and broke away from mutually between second group of ratchet and be in non-engagement state, and entire mechanism can be carried out the forward intermittent movement.External force acts on the control hand lever, the control hand lever is pressed downward to the terminal back half-twist of the yi word pattern groove of body, yi word pattern boss on the control hand lever is subjected to the plane restriction of groove end face and locatees, this moment, first group of ratchet broke away from, second group of ratchet under the effect of control hand lever is meshing with each other, and entire mechanism can be carried out reverse intermittent movement.Need to change in actual production life under the occasion of moving direction of intermittent movement, this mechanism can control the varying motion direction easily.
