Abstract
The invention discloses a presser foot with an adjustable height for a sewing machine. The presser foot comprises the presser foot, an upright column, and a connection sleeve with inner screw threads. The presser foot and the upright column are respectively provided with a first spiral section and a second spiral section, the first spiral section and the second spiral section are both provided with outer screw threads matched with the inner screw threads of the connection sleeve, and the presser foot and the upright column are connected through the connection sleeve. Inner screw threads of the first spiral section are screwed into the connection sleeve, and by controlling the screwing amount, the height of the presser foot is controlled. When the screwing amount is more, the position of the presser foot is higher; and when the screwing amount is less, the position of the presser foot is lower.
Description
Technical field
The present invention relates to a kind of accessaries of sewing machine, especially sewing-machine foot.
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 dumbly, and it is not attractive in appearance to make effect, the sewing route inaccuracy.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of sewing-machine foot that can regulate height.
For addressing the above problem, the invention provides a kind of height adjustable sewing machine presser feet, comprise presser feet and vertical rod, and the adapter sleeve that is provided with internal thread, be respectively equipped with the first spiral section and the second spiral section in described presser feet and the vertical rod, be equipped with the external screw thread that matches with the internal thread of described adapter sleeve on described the first spiral section and the second spiral section, connect by adapter sleeve between described presser feet and the vertical rod.
As a further improvement on the present invention, be respectively equipped with the first double nut and the second double nut on described the first thread segment and the second spiral section.
As a further improvement on the present invention, be provided with the first stop washer between described the first double nut and adapter sleeve, be provided with the second stop washer between described the second double nut and adapter sleeve, described the first stop washer, the second stop washer all have foldable salient angle.
Beneficial effect:
(1) by adapter sleeve presser feet is connected with vertical rod, the length of regulating the first spiral section screw-in adapter sleeve of presser feet just can be regulated the height of presser feet;
(2) by the first double nut and the second double nut, the first spiral section, the second spiral section are fixed with adapter sleeve;
(3) double nut and adapter sleeve directly are provided with stop washer, prevent that double nut is loosening.
Figure of description
Fig. 1 is the cutaway view of the present invention's height adjustable sewing machine presser feet;
Fig. 2 is the partial structurtes schematic diagram of the present invention's height adjustable sewing machine presser feet,
Wherein: presser feet 1, the first spiral section 12, the first double nut 13, the first stop washer 14, vertical rod 2, the second spiral section 22, the second double nut 23, the second stop washer 24, adapter sleeve 3.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
As depicted in figs. 1 and 2, the present invention includes and comprise presser feet 1 and vertical rod 2, and the adapter sleeve 3 that is provided with internal thread, be respectively equipped with the first spiral section 12 and the second spiral section 22 in presser feet 1 and the vertical rod 2, be equipped with the external screw thread that matches with the internal thread of adapter sleeve 3 on the first spiral section 12 and the second spiral section 22, connect by adapter sleeve 3 between presser feet 1 and the vertical rod 2.Be respectively equipped with the first double nut 13 and the second double nut 13 on the first spiral section 21 and the second spiral section 22.3 of the first double nut 13 and adapter sleeves are provided with the first stop washer 14, the second double nuts 13 and 3 of adapter sleeves are provided with the second stop washer 14, and described the first stop washer 14, the second stop washer 14 all have foldable salient angle.
During use, in the internal thread screw-in adapter sleeve 3 with the first spiral section 12, by the amount of control screw-in, thus the height of control presser feet 1.When the amount that screws in was more, the position of presser feet 1 was higher; When the amount that screws in was less, the position of presser feet 1 was lower.
After presser feet 1 Height Adjustment is complete, screw the first double nut 13 and the second double nut 13, make it press closer adapter sleeve 3, be fixed, the presser feet 1 after preventing from regulating rotates with respect to adapter sleeve 3 or is mobile.
After screwing the first double nut 13 and the second double nut 13, salient angle on the first stop washer 14, the second stop washer 14 is turned up, be tight against the first double nut 13 and the second double nut 13 side faces, prevent that the first double nut 13 and the second double nut 13 are loosening.
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.
