Abstract
The utility model discloses a presser foot device of a sewing machine. The presser foot device comprises a base plate and a vertical rod which are perpendicular to each other, wherein one end of the base plate is hinged with the vertical rod, and a part of the base plate extends out of the vertical rod; and a bulge which is perpendicular to the base plate is arranged on the extended part, and one edge of the bulge pushes against the vertical rod. The presser foot device also comprises an anti-rotation mechanism for preventing the base plate from rotating around a hinged point; the base plate can rotate around the hinged point; when the base plate is rotated, the base plate is lifted up; the bulge is arranged on the base plate; and when the base plate rotates to a perpendicular position, rotation of the base plate is continuously stopped, so that limitation can be realized.
Description
Technical field
The utility model 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 to make turning dumb, make effect not attractive in appearance, sewing route inaccuracy, lifting presser feet continue to make again and have delayed the time and lowered efficiency.
The utility model content
The technical problems to be solved in the utility model is to solve the foot device of conveniently mentioning.
For addressing the above problem, the utility model 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 further improvement of the utility model, 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 chute, and guide rod is provided with bolt, and bolt matches with the screw that is arranged on base plate.
As further improvement of the utility model, be hinged with first connecting rod in vertical rod, be hinged with second connecting rod on base plate, the hinged and pin joint of first connecting rod and second connecting rod is provided with fastening bolt.
As further improvement of the utility model, 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 guide rod is screwed in 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 base plate are hinged, fix by the fastening bolt that is arranged on 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 the utility model sewing-machine foot device;
Figure 2 shows that the structural representation of the second specific embodiment of the utility model sewing-machine foot device;
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 utility model is described in further details.
Fig. 1 is the structural representation of the utility model the first specific embodiment, 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 on one side the projection 26 of vertical rod 2, 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 chute 21, guide rod 22 is provided with bolt 23, and bolt 23 matches with the screw 11 that is arranged on 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 base plate 1 is held by crotch 25; , frenulum 24 can be separated with crotch 25 during with base plate 1 reposition when needs, 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 screw 11, was fixed.
Figure 2 shows that the structural representation of the utility model the second embodiment, 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 on one side the projection 26 of vertical rod 2, be hinged with first connecting rod 201 in vertical rod 2, be hinged with second connecting rod 101 on base plate 1, hinged and pin joint is provided with fastening bolt 3 with second connecting rod 101 for first connecting rod 201, when needs lift base plate 1, unclamp fastening bolt 3, mention base plate 1 and again fastening bolt 3 is tightened behind enough positions; , base plate 1 is rotated during with base plate 1 reposition when needs, 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 embodiment of the present utility model by reference to the accompanying drawings, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
