Description
The utility model relates to sewing locomotive needle lock, refer in particular to a kind of on the car needle lock except being provided with needle tray, between two needle trays, be provided with left front cutter groove more again, reach left front cutter and car pin energy synchronous operation, promptly when making the right and left suture, also cut apart with a knife or scissors in the middle of two sutures by the left front cutter simultaneously.
Will make the technology of the structure of a left front at present, be to utilize earlier to have the thread Sewing machines of car pin of double slit to make two sutures earlier on dress material, takes off cloth at last again and with scissors or blade it is cut apart with a knife or scissors.
Common sewing locomotive needle lock is shown in Figure 1A, 1B, the screw rod 11 of this car needle lock 1 mat upper end is installed up to the driving mechanism (figure does not show) of Sewing machines, its both sides are provided with screw and adjust bolt 13 so that lock, a base 10 is forwards extended in the lower end, the plate face of base 10 is provided with through wires hole 12, for threading; Be provided with needle tray 14 in car needle lock 1 inside for locking the car pin, the car pin of locking mat adjustment bolt 13 screw-ins again grips.
Constitute by above-mentioned, when car needle lock 1 moves up and down, reach the purpose of making because of trying to make a match.
Only common sewing locomotive needle lock has following shortcoming in use:
(1) only can merely be useful in and make, can't once reach the type of making of opening of left front button hole, must after using Sewing machines, cut out with artificial again.
(2) common left front causes the tediously long and waste of manpower resource of production time easily if utilize artificial manufacture process, increases cost.
(3) utilization of left front button hole manually cut out sanction line after the processing have bigger error and about distortion.
The purpose of this utility model is to provide a kind of improved sewing locomotive needle lock, can select whether the left front cutter to be installed on the car needle lock according to the difference of making purpose, when the installation of left front cutter, the left front opening sutural while of the left and right sides can sewed up, the left front cutter can reach and make and open the flap and finish synchronously along with the suture needle running up and down synchronously together that is fixed on equally on the car needle lock.
For reaching above-mentioned purpose, the utility model mainly comprises: the two-needle sewing machine needle stand, needle tray and through wires hole, the car needle lock is adjusted bolt, be characterized in: the rear side on the car needle lock in the middle of two needle trays is provided with a left front cutter groove, and left front cutter groove inside can be for wearing the left front cutter, and the position to left front cutter groove is provided with left front cutter adjustment bolt relatively in the fixator both sides, so that the left front cutter is tightened with instrument after putting into left front cutter groove, prevent that the left front cutter from coming off in use or loosening.
In addition, being provided with in the upper end that the car needle lock is adjusted bolt can for checking whether the car pin installs to the peep pole of vertex position, with the lower end pin mark of determining two car pins whether on same horizontal plane, to guarantee quality of sewing.
The utility model has following advantage:
1, can sew up the left front opening sutural while of the left and right sides, can make the suture needle running up and down synchronously together on the car needle lock equally, reach and make and open the flap and finish synchronously.
2, the simple structure of two-needle sewing machine car needle lock is cheap for manufacturing cost.
3, utilize this kind of car needle lock to shorten working hours, reduce manpower, help product cost to reduce and manufacturing efficient.
4, the sanction line that utilizes this left front cutter to cut out out is more neat and attractive in appearance.
Below in conjunction with accompanying drawing structure of the present utility model, technical characterictic are described further:

The detailed description of embodiment:
The utility model sewing locomotive needle lock, shown in Fig. 2,3, car needle lock 2 has the screw rod 21 identical with common car needle lock, car pin and adjusts bolt 22, base 23, through wires hole 24, car pin 25 and needle tray 26, below partly describes in detail as the back at improving:
Shown in Fig. 2,3, car needle lock 2 of the present utility model, dead astern between two needle trays 26 is provided with left front cutter groove 3 in addition, the both sides of car needle lock 2 are provided with left front cutter adjustment bolt 41,42 to the position of left front cutter groove 3 relatively, so, after left front cutter 5 is put into left front cutter groove 3 from the bottom up, adjust bolt 41,42 with the left front cutter and be tightened, can prevent that left front cutter 5 from may produce in use come off or loosening; After the car pin is fixed into needle tray 26, can reaches and in sewing, can finish left front synchronously again and open system.
Because the both sides, the left and right sides of car needle lock 2 is provided with symmetrically arranged adjustment bolt hole, therefore, when fixing car pin, similarly also be after car pin 25 is correctly inserted pin hole groove 26, utilize the adjustment bolt of the left and right sides respectively two car pins 25 to be fixedly clamped again, just can allow Sewing machines when running, car needle lock 2 can drive two car pins 25 and these left front cutter 5 knee-actions simultaneously, allow the user when making as left front partly, only need left front cutter 5 added and install, just can reach the left front opening that when seam is knitted, synchronously utilizes left front cutter 5 to cut apart with a knife or scissors institute's palpus.
In addition, on the car needle lock 2, more be provided with peep pole 6 in order to screw in the keyhole upper end of adjusting bolt 22, peep pole 6 extends through the upper end of needle tray 26 from both sides, can learn whether car pin 25 arrives the position on summit when packing needle tray 26 from the bottom up into from peep pole 6, with the lower end pin mark of determining two car pins 25 whether on same horizontal plane, to guarantee quality of sewing
Must be pointed out, more than be most preferred embodiment of the present utility model, if comply with the change that design of the present utility model is done, the function of its generation all belongs to protection domain of the present utility model when not exceeding specification and letter shown in the drawings lid spirit yet.
