Abstract
The invention discloses a sewing machine presser foot device, which comprises a base plate and an upright columnwhich are mutually perpendicular, one end of the base plate is hinged with the column and a part of the base plate extends out of the upright column, the extended part of the base plate is provided with a bulge which is perpendicular to the base plate and with one edge resisting to the column, the sewing machine pressing plate device further comprises an anti-rotation mechanism preventing the base plate from rotating around a hinged point, the base plate is capable of rotating around the hinged point, the base plate is only needed for being rotated so as to lift the base plate, since the bulge is arranged on the base plate, when the base plate rotates to a vertical position, the base plate is prevented from continuously rotating, and limiting can be further realized.
Description
Technical field
The present invention relates to a kind of sewing-machine foot device.
Background technology
Sewing-machine foot is requisite parts in the feed mechanism of Sewing machines, sewing-machine foot plays very important effect in process of production, as being used for seizing open-wire line, hidden type slide fastener sewing machine special presser feet, pleating sewing-machine foot etc., presser feet is in the process of using, because in suture needle and presser feet certain distance is arranged, so making when turning round line, 2 stop cloth so that turn dumb, make effect not attractive in appearance, sewing route inaccuracy, lifting presser feet continue to make again and have delayed the time and lower efficiency.
Summary of the invention
The technical problem to be solved in the present invention is to solve the foot device of conveniently mentioning.
For addressing the above problem, the invention provides the sewing-machine foot device, comprise perpendicular base plate and vertical rod, base plate one end and vertical rod is hinged and part is stretched out vertical rod, the extending area is provided with vertical with base plate and props up on one side the projection of vertical rod, and the Sewing machines presser device also comprises the rotation-preventing mechanism that prevents that pin joint from rotating.
As a further improvement on the present invention, rotation-preventing mechanism comprises and is arranged on vertical rod inboard, from top to down and extend to the chute of base plate, is provided with the guide rod perpendicular with chute on the chute, and guide rod is provided with bolt, and bolt matches with the screw that is arranged on the base plate.
As a further improvement on the present invention, be hinged with first connecting rod in the vertical rod, be hinged with second connecting rod on the base plate, the hinged and pin joint of first connecting rod and second connecting rod is provided with fastening bolt.
As a further improvement on the present invention, guide rod is provided with frenulum, and the top of chute is provided with for the crotch of holding frenulum.
Beneficial effect:
(1) base plate can rotate around pin joint, in the time of mentioning base plate, only needs rotary bottom plate;
(2) base plate is provided with projection, when base plate forwards the upright position to, stops it to be rotated further, and then spacing;
(3) bolt in the guide rod is screwed in the screw, and the base plate upright position is fixed;
(4) guide rod is provided with frenulum, and vertical rod is provided with for the crotch of holding frenulum, is used for preventing that guide rod from falling;
(5) first connecting rod and the second connecting rod employing that are hinged on respectively on vertical rod and the base plate are hinged, fix by the fastening bolt that is arranged on the pin joint, and then the position of fixed base plate.
Description of drawings
Figure 1 shows that the structural representation of the first specific embodiment of sewing-machine foot device of the present invention;
Figure 2 shows that the structural representation of the second specific embodiment of sewing-machine foot device of the present invention;
Wherein: base plate 1, screw 11, second connecting rod 101, vertical rod 2, chute 21, guide rod 22, bolt 23, frenulum 24, crotch 25, projection 26, first connecting rod 201, fastening bolt 3.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
Fig. 1 is the structural representation of the first specific embodiment of the present invention, comprise perpendicular base plate 1 and vertical rod 2, hinged and the part of base plate 1 one ends and vertical rod 2 is stretched out vertical rod 2, the extending area is provided with vertical with base plate 1 and props up the projection 26 of vertical rod 2 on one side, vertical rod 2 inboards, be provided with from top to down and extend to the chute 21 of base plate 1, be provided with the guide rod 22 perpendicular with chute 21 on the chute 21, guide rod 22 is provided with bolt 23, and bolt 23 matches with the screw 11 that is arranged on the base plate 1.Guide rod 22 is provided with frenulum 24, and the top of described chute 21 is provided be used to the crotch 25 of holding described frenulum 24.Adopt such structure, when needs lift presser feet, can be with base plate 1 to vertical rod 2 rotations, until the frenulum 24 on the base plate 1 is held by crotch 25; When needs during with base plate 1 reposition, frenulum 24 can be separated with crotch 25, base plate 1 rotates, until projection 26 props up, this moment, base plate 1 was vertical with vertical rod 2, and bolt 23 is stubborn as in the screw 11, was fixed.
Figure 2 shows that the structural representation of the second embodiment of the present invention, comprise perpendicular base plate 1 and vertical rod 2, hinged and the part of base plate 1 one ends and vertical rod 2 is stretched out vertical rod 2, the extending area is provided with vertical with base plate 1 and props up the projection 26 of vertical rod 2 on one side, be hinged with first connecting rod 201 in the vertical rod 2, be hinged with second connecting rod 101 on the base plate 1, hinged and the pin joint of first connecting rod 201 and second connecting rod 101 is provided with fastening bolt 3, when needs lift base plate 1, unclamp fastening bolt 3, mention base plate 1 and behind enough positions, again fastening bolt 3 is tightened; When needs during with base plate 1 reposition, base plate 1 is rotated, until projection 26 props up, this moment, base plate 1 was vertical with vertical rod 2, and fastening bolt 3 is tightened, and was fixed.
The above describes in detail embodiments of the present invention by reference to the accompanying drawings, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
