Description
Technical field
The utility model is related to the interior presser foot device that one is installed on sewing machine headstock, particularly relate to it is a kind of in eedle from sewing
The interior presser foot device for pushing down sewing object can be used when being extracted in object.
Background technology
Tradition drives the sewing machine of cloth movement without using feeding tooth, to prevent the friction between cloth and eedle, causes
Cloth rises together with eedle and generates bouncing pilotage, usually can all be installed with foot device in one.
For foot device when eedle declines, once internal pressure foot bottom is in contact with cloth, then interior presser feet will not in general
Again as eedle continues to decline, and the state of cloth is pushed down, also, begin to ramp up in the eedle through cloth by elastic force maintenance
When, equally make interior presser feet that a pressed status be presented by elastic force, cloth can be pressed by interior presser feet, until eedle rises
To hooking is completed or after leaving cloth, interior presser feet carries out upward stroke with eedle again, so as to moving cloth, however, in response to
The difference in thickness that various clothes or laminated number generate, interior presser feet should also have in addition to that need to have the periodic up and down motion
The function of adjustable stroke height and position up and down.
Please refer to Fig.1 and Fig. 2 shown in, it is known that the interior foot device 10 of sewing machine has in one that presser feet shakes in presser feet 11, one
Presser feet link component 13 in component 12, one, presser feet mobile member 15, a lifting member 16 in a guiding elements 14, one are moved,
In, the interior presser feet link component 13 is configured between the interior presser feet 11 and interior presser feet mobile member 15, and by two concatenations
Connecting rod 131,132 formed, and the upper end of the guiding elements 14 can be installed in turn a sewing machine headstock (figure not
Show), and the slot hole 141 of a vertical direction is formed in lower end, wherein, the engaging portion 133 between two connecting rod 131,132
It is slidably mounted in the slot hole 141.
The interior presser feet mobile member 15 is then connected between 14 and one drive member 17 of guiding elements, and described
There is lifting member 16 presser feet lifting part 162, the rotation axis 161 in a rotation axis 161 and one to pass through a bevel gear group
163 and be assembled in the drive member 17, and with a lifting cam 164, and interior presser feet lifting part 162 be pivotally connected to it is described
Sewing machine, and the contact roller 165 for contacting at the lifting cam 164 with one.
The drive member 17 rotated in the range of 0~180 degree, although at this point, the lifting cam 164
Maintenance portion can be contacted with the contact roller 165, but the interior presser feet lifting part 162 can't rotate, meanwhile, the driving
Component 17 drives the interior presser feet mobile member 15 to be moved, and the slot hole 141 of the guiding elements 14 is driven to drive the knot
Conjunction portion 133 moves horizontally, and changes the arrangement angle of two connecting rod 131,132, so as to adjust under the interior presser feet 11
The height and position of position.
In addition, when the drive member 17 is rotated in the range of 180~360 degree, the lifting cam 164
Change section can be contacted with the contact roller 165 so that the interior presser feet lifting part 162 can be rotated, and then make in described
One end of presser feet lifting part 162 drives the interior presser feet 11 to rise to retreating position.
However, two connecting rods, 131,132 institute that the interior foot device 10 must be set by guiding elements 14 in conjunction with in-line row
The link component of composition begins that the height and position of the lower position of presser feet 11 in adjustment can be reached, also, must also pass through lifting member
The interior presser feet 11 is moved to retreating position by 16, and only the structure composition of additional guide member and lifting member 16 is removed and made
Into except the interior 10 overall volume increase of foot device, the guiding elements 14 of particular aspects and the structure group of lifting member 16
Increase into the cost on making is also resulted in, therefore, there is the necessity for improveing aforementioned missing in fact.
