Abstract
The invention relates to a needle connecting device of a sewing machine. The machine head of the sewing machine is connected with a single needle bar, and the lower end of the needle bar is provided with at least two needles. The needle connecting device is characterized by comprising a strip-shaped flat plate connected with the single needle bar of the sewing machine, and a slide block connected with the upper end of the sewing machine needle, wherein a long slot is formed on the flat plate along the lateral direction, and the slide block can laterally slide along the long slot. Scale lines can be arranged on the flat plate along the movement direction of the slide block, so that the distance between the needles is adjustable based on the scale lines, thereby conveniently achieving accurate distance, recording distance values, facilitating the reappearance of specific values and improving the sewing quality and stability; and a rubber layer is arranged at the large-head end of a screw, thereby better locking the needle position.
Description
Technical field
The present invention relates to the jockey between a kind of needle bar of sewing machine and eedle, relate in particular to a kind of single needle bar and connect multimachine pin, the adjustable jockey of needle gage between eedle.
Background technology
People need use many eedles when the privileged site that utilizes the stitching sewing machine clothes and some styles, produce many rows arranged side by side and stitch mark.Using maximum is double needle lockstitch machine, and it is linked to each other with two eedles through contiguous block by a single needle bar usually, fixes with screw between eedle and contiguous block, and is not movable.Unadjustable because of distance between two eedles, cause its bad adaptability to demands of different seam mark, also very bother and constantly change the eedle that needle gage do not wait.
Chinese patent CN200920117012.7 discloses " the adjustable single needle knock-off joint of a kind of pin spacing device ", has solved the nonadjustable problem of distance between eedle.Said device comprises the adjusting bracket that is fixed on the shank bottom, on adjusting bracket, is provided with the regulating block that several can move horizontally with respect to adjusting bracket, on each regulating block, is fixed with an eedle respectively.Though the distance scalable is inaccurate between said eedle, is unfavorable for the distance value that repeatedly setting is crossed.
Summary of the invention
The present invention has overcome the deficiency of prior art, provides a kind of simple in structure, and pin spacing is accurate, favorable reproducibility, needle bar of sewing machine that the eedle stationarity is high and the jockey between eedle.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of sewing machine needle jockey, said head of sewing machine are connected with a single needle bar, and the shank lower end is equipped with at least two eedles; It is characterized in that: comprise the strip shape transverse slat that links to each other with Sewing machines single needle bar; With the slide block that is connected the sewing machine needle upper end, along laterally having elongated slot, said slide block can laterally slide along elongated slot on the said transverse slat.
In preferred embodiment of the present invention, comprise that further said transverse slat surface is decorated with graduation mark along the slide block movement direction.
In preferred embodiment of the present invention, comprise that further said graduation mark is positioned at the transverse slat upper surface.
In preferred embodiment of the present invention, further comprise said transverse slat lower surface, the slide block outside is provided with a longitudinal extension plate, and said elongated slot is along laterally opening on extension board, and graduation mark is decorated with along the slide block movement direction in the extension board surface.
In preferred embodiment of the present invention, comprise that further said graduation mark is positioned on the lateral surface of extension board with respect to slide block.
In preferred embodiment of the present invention, comprise further in the said elongated slot being installed with screw that screw is connected with the slide block of transverse slat below, the threaded portion of said screw passes elongated slot just.
In preferred embodiment of the present invention, comprise that further the big end inboard of said screw is stained with rubber layer.
The invention solves the defective that exists in the background technology; Jockey between needle bar of sewing machine provided by the invention and eedle, distance is not only adjustable between eedle, also has the graduation mark contrast; Conveniently realize distance accurately; Write down distance value, and be beneficial to the reproduction of special value, improve sewing quality and stability.The inboard rubber layer that adds of the screw stub end of locking eedle position can increase the friction with joint face, stablize the eedle position better, and is mobile.Screw is arranged on the stringer board in the slide block outside, and it is more attractive in appearance that whole device it seems from the front.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Fig. 2 is the rearview of the preferred embodiments of the present invention;
Fig. 3 is the partial side view that screw connects in the preferred embodiments of the present invention;
Among the figure: 1, shank 2, transverse slat 3, eedle 4, slide block 5, screw 6, extension board 7, bar-shaped trough 8, rubber layer 9, graduation mark 10, hold-down screw.
The specific embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Like Fig. 1, Fig. 2, shown in Figure 3; Jockey mainly comprises the strip shape transverse slat (2) that the upper end links to each other with Sewing machines single needle bar (1); Be arranged at transverse slat below, vertically be connected with the slide block (4) of sewing machine needle (3), slide block (4) is two or more; Can slide along transverse slat (2) length direction with respect to transverse slat (2), and can pass through screw (5) fixed position.Said transverse slat (2) lower surface, slide block (2) arranged outside has a strip shape longitudinal extension plate (6), and transverse slat (2) and extension board (6) are the smooth flat board of inner surface.Said slide block (2) has a smooth flat top surface, pastes mutually with transverse slat (2) inner surface, has the side of a smooth to paste mutually with extension board (6) inner surface.Have bar-shaped trough (7) on the said extension board (6) along its length, the threaded portion of screw (5) is horizontally through said bar-shaped trough (7) just and is connected with the slide block (4) of transverse slat (2) below, and the big end inboard of screw (5) is stained with rubber layer (8).Extension board (6) is provided with even graduation mark (9) with respect to lateral surface upper edge slide block (4) direction of motion of slide block (4).Eedle (3) is connected with slide block (4) through hold-down screw (10).
During use, the slide block (4) that will be connected with eedle (3) places transverse slat (2) and extension board (6) inboard, and slide block (4) upper surface is adjacent to transverse slat (2) lower surface; Slide block (4) side is adjacent to extension board (6) medial surface; Pass bar-shaped trough (7) with screw (5) from extension board (6) outside, link to each other, in bar-shaped trough (7), move screw (5) with said slide block (4); According to the graduation mark (9) on the extension board (6), regulate distance between each eedle (3).After confirming distance, screw (5) is tightened to slide block (4) direction, made the rubber layer (8) of the big end of screw (5) be close to extension board (6) lateral surface, secure lock eedle (3) position.
