Abstract
The invention discloses a needle replacing mechanism for a computer sewing machine. According to the technical scheme, the needle replacing mechanism is characterized in that the needle replacing mechanism comprises a machine head, the machine head is provided with a mounting hole, a fixing rod is arranged in the mounting hole in a penetrating mode, one end of the fixing rod is provided with gaps, the number of the gaps is two, one side of the machine head is provided with a mounting groove, a control rod is arranged in the mounting groove, a hinge shaft is arranged between the control rod and the mounting groove and located in the middle of the control rod, and the upper end of the control rod is hinged to the fixing rod. In this way, by means of the needle replacing mechanism for the computer sewing machine, needles can be replaced more conveniently and faster.
Description
Technical field
The present invention relates to a kind of sewing device, particularly relate to a kind of needle exchange mechanism of computer flat sewing machine.
Background technology
Sewing machine for covering chain stitch mainly uses a sewing thread, and sewing is formed a kind of stitching, makes the machine that one or more layers sewing interweaves or unites by a seam.Usually be divided into thin material and thick material two kinds of purposes, sewing machine for covering chain stitch can make the goods such as the fabrics such as cotton, fiber crops, silk, hair, artificial fibre and leather, plastics, paper, and thin material is generally used for knitting, underwear, shirt, uniform etc., thick material is generally used for all kinds of sportswear, jean, fashionable dress, overcoat, shoes and hats, skin is young, case and bag etc., flat seam machine is the most basic car type at sewing device, in making, be the simplest stitching, the stitching neat appearance sewed, stitching are even, firmly smooth.
But because when computer flat sewing machine makes thing in use, because the material made and the decorative pattern made or all need when adopting different lines to change different pins, but needle exchange of the prior art is cumbersome so have the space of improvement.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, make the needle exchange mechanism needle exchange of computer flat sewing machine convenient, a kind of needle exchange mechanism of computer flat sewing machine is provided, comprise head, described head is provided with installing hole, fixed bar is equipped with in described installing hole, one end of described fixed bar is provided with gap, described gap is two, the side of described head is provided with mounting groove, control lever is provided with in described mounting groove, jointed shaft is provided with between described control lever and described mounting groove, described jointed shaft is positioned in the middle part of described control lever, upper end and the described fixed bar of described control lever are hinged.
Further, the bottom of described control lever is provided with fixture.
Further, the bottom of described installing hole is provided with retainer ring, and described fixing surrounding place side is provided with some balls.
Compared with prior art, the invention has the beneficial effects as follows: so in use because be provided with rotating shaft between control lever and mounting groove, and the upper end of control lever and fixed bar are hinged, like this in time upwards lifting control lever, because the effect of control lever makes fixed bar move down, along installing hole slide downward, because fixed bar is provided with gap, like this when fixed bar will to external diffusion without the restriction of installing hole, thus pin is loosened in fixed bar, so just pin can be taken off, put in fixed bar by anti-for required pin again, to leave behind control lever, it is made to get back to original position, thus drive fixed bar to get back in installing hole, thus make fixed bar contraction make pin be fixed in fixed bar, this completes the work of needle exchange, easy to operate simple and fast.
Accompanying drawing explanation
Fig. 1 is the structural representation of the needle exchange mechanism of computer flat sewing machine of the present invention;
Fig. 2 is the front view of retainer ring.
In figure 1, head; 2, installing hole; 21, retainer ring; 211, ball; 3, fixed bar; 31, gap; 4, mounting groove; 5, control lever; 51, jointed shaft; 52, fixture.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
The needle exchange mechanism of a kind of computer flat sewing machine of the present invention, comprise head 1, described head 1 is provided with installing hole 2, fixed bar 3 is equipped with in described installing hole 2, one end of described fixed bar 3 is provided with gap 31, described gap 31 is two, the side of described head 1 is provided with mounting groove 4, control lever 5 is provided with in described mounting groove 4, jointed shaft 51 is provided with between described control lever 5 and described mounting groove 4, described jointed shaft 51 is positioned in the middle part of described control lever 5, and upper end and the described fixed bar 3 of described control lever 5 are hinged.
So in use because be provided with rotating shaft between control lever 5 and mounting groove 4, and the upper end of control lever 5 and fixed bar 3 are hinged, like this in time upwards lifting control lever 5, because the effect of control lever 5 makes fixed bar 3 move down, along installing hole 2 slide downward, because fixed bar 3 is provided with gap 31, like this when fixed bar 3 will to external diffusion without the restriction of installing hole 2, thus pin is loosened in fixed bar 3, so just pin can be taken off, put in fixed bar 3 by anti-for required pin again, to leave behind control lever 5, it is made to get back to original position, thus drive fixed bar 3 to get back in installing hole 2, thus make fixed bar 3 contraction make pin be fixed in fixed bar 3, this completes the work of needle exchange, easy to operate simple and fast.
The bottom of described control lever 5 is provided with fixture 52.
Just preventing from causing control lever 5 automatically to upspring because moving fast in the process of its work by fixture 52 like this, making dropping of pin, cause the inconvenience of use and prevent from causing damage to staff.
The bottom of described installing hole 2 is provided with retainer ring 21, and described retainer ring 21 weeks sides are provided with some balls 211.
Like this by the effect of ball 211, fixed bar 3 is skidded off in installing hole 2 more smooth and easy, thus make control operation bar more light.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
