Description
Technical field
The present invention relates to a kind of bobbin case, be meant a kind of Sewing machines bobbin case especially.
Background technology
As shown in Figure 4, the structure of present employed Sewing machines bobbin case is: comprise body 1 and the Trap shell splinter 2 that is connected with body 1, described body 1 comprises diapire 11, the perisporium 12 that extends up from diapire 11 peripheries and the central shaft 13 that is arranged on diapire 11 centers and is provided with vertically, be provided with breach 14 in the perisporium 12, breach 14 is through to diapire 11 down from the apical margin of perisporium 12, be provided with yarn guide channel 15 in the perisporium 12, yarn guide channel 15 runs through perisporium 12 down from the apical margin of perisporium 12, diapire 11 is provided with wire guide rob 3, and wire guide rob 3 is positioned under the breach 14; Described Trap shell splinter 2 be arranged on the outside of perisporium 12 and and perisporium 12 between have the gap, the bottom of yarn guide channel 15 is positioned at the perisporium zone that Trap shell splinter 2 is blocked, the end of Trap shell splinter 2 is a thread hook 21, is provided with wire guide 16 in the perisporium 12 of thread hook 21 correspondence position positions.
As shown in Figure 5, when above-mentioned Sewing machines bobbin case uses, line wheel 4 is sheathed in the central shaft 13 rotationally, and the suture 5 in the line wheel 4 can be imported into this yarn guide channel 15, and is led to wire guide 16 places through Trap shell splinter 2, and supported by thread hook 21, and then pass wire guide rob 3 and be drawn out along the smooth outer peripheral face of perisporium 12, so, when Sewing machines carries out sewing, suture 5 can be under the situation of certain tension force, is drawn out with fixing linear flow rate and carries out sewing.
The shortcoming of above-mentioned Sewing machines bobbin case is: as shown in Figure 6; because the outer peripheral face of perisporium 12 is to be smooth shape; therefore suture 5 usually can slide on the diapire 11 from perisporium 12; cause suture 5 that the situation of tension force shakiness takes place; so; promptly can change to the linear flow rate of suture 5, and the sewing effect of Sewing machines is impacted.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of suture that can make can not slide into Sewing machines bobbin case on the diapire from perisporium, thereby can stablize thread tension, improve the sewing effect of Sewing machines.
For addressing the above problem, the technical solution used in the present invention is: the Sewing machines bobbin case, comprise body and the Trap shell splinter that is connected with body, described body comprises diapire, the perisporium that extends up from the diapire periphery and the central shaft that is arranged on the diapire center and is provided with vertically, be provided with breach in the perisporium, breach is through to diapire down from the apical margin of perisporium, be provided with yarn guide channel in the perisporium, yarn guide channel runs through perisporium down from the apical margin of perisporium, diapire is provided with wire guide rob, wire guide rob be positioned at breach under; Also and between the perisporium there is the gap in the outside that described Trap shell splinter is arranged on perisporium, the bottom of yarn guide channel is positioned at the perisporium zone that Trap shell splinter blocks, the end of Trap shell splinter is a thread hook, be provided with wire guide in the perisporium of thread hook correspondence position, be provided with wire grooves in the described perisporium, wire grooves is between wire guide and wire guide rob, and wire grooves is connected with breach.
Described wire grooves is obliquely installed vertically, and its end position near wire guide is higher than the end position near wire guide rob.
Described wire guide rob is a leptospira structure.
The invention has the beneficial effects as follows: above-mentioned Sewing machines bobbin case by wire grooves spacing to suture, can make suture maintain under the stable tension situation, and effectively control the linear flow rate of suture, and then make Sewing machines can produce good sewing effect.
