Abstract
The utility model provides a closed sewing machine swinging shuttle, which comprises a swinging shuttle body, a shuttle core shell, a shuttle latch, a spring and a thread pressing reed. The swinging shuttle body is a bow-shaped body with chordal connection in an enclosed type. The top tip of the shuttle body is a straight tip and a needle slope is a long needle slope. The inner part of a convex hole on the bow back of the shuttle body is provided with the spring connected with the shuttle latch. The utility model has novel structure, reasonable design, tight match, firmness, duality and convenient use. The utility model is suitable for thick stuff sewing machines, sole fixing machines, sack tailoring machines, etc. The utility model is a new accessory of the sewing machine.
Description
The utility model relates to a kind of loop taker of Sewing machines, especially a kind of swing type shuttle.
In sewing machine, existing shuttle mainly is made up of shuttle main body, bobbin casing, shuttle door bolt and line ball reed, and bobbin casing and shuttle door bolt are connected in shuttle main body by its bobbin casing shaft coupling and shuttle door bolt pivot pin respectively, and the line ball reed is fixedly connected on the bobbin casing by screw.As existing GA5-1 type open type shuttle is exactly this structure.Because the string portion of shuttle main body is not connected to opening shape structure, its processing and heat treatment are yielding, bulk strength is poor, service life is low, in use easily cause disconnected body and plug line broken string, again because the top tip part of existing shuttle main body is an arc point structure, and the pin slope is less, usually pin length of grade degree is 8 millimeters only, and shuttle is taken an unnecessary way when forming the line cover colluding to reach the standard grade, and also causes institute's sewing thickness to be restricted, the shuttle door bolt easily produces elastic fatigue for curved arc cantilevered shuttle door bolt, thereby cause bobbin casing and the slippage of shuttle body sometimes in using, and influence the operate as normal of Sewing machines, make troubles to use.
The purpose of the utility model provide a kind of novel structure, reasonable in design, cooperate novel sewing machine shuttle tight, easy to use.
For achieving the above object, the technical scheme that the utility model is taked is: shuttle main body is designed to the closed arc that connects string, the top top and elongated pin slope of straight type that is designed to of shuttle main body, and bottom the back of a bow of shuttle body load shuttle door bolt, install a spring connection shuttle door bolt, the enclosed novel sewing machine shuttle that consists of.During use, press the shuttle door bolt, dial the commentaries on classics bobbin casing and outside shuttle main body, transfer, shuttle is packed in the bobbin casing, pass the bobbin casing return and by the shuttle door bolt bobbin casing door bolt is connected fixingly, again the sewing thread in the shuttle is pulled out, at last this shuttle is installed in the Sewing machines shuttle race, just can carries out sewing operation.
Because the utility model has adopted the shuttle structure of closed shuttle body, bulk strength height, service life can be enhanced about more than once, also be easy to processing and manufacturing, can solve the disadvantage of resolving body and broken string effectively, the top top and elongated pin slope of straight type that is designed to of shuttle body, make shuttle collude line more direct simple and direct, increased sewing thickness, expanded the sewing scope, improved the performance of Sewing machines.Therefore, the utility model is compared with existing shuttle, its novel structure, reasonable in design, cooperate closely, sturdy and durable, easy to use, be applicable to thick stuff sewing machine, sole-fixing machine, bottom making machine, gunnysack tailoring machine etc., be a kind of novel accessaries of sewing machine.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the partial sectional view of the utility model embodiment concrete structure.
Fig. 2 is that the A of shuttle main body among Fig. 1 (1) is to view.
Mark in the accompanying drawing: 1 shuttle main body, 2 bobbin casings, 3 shuttles door bolt, 4 springs, 5 line ball reeds.
As accompanying drawing 1,2 illustrated embodiments, the utility model comprises; Shuttle main body (1), bobbin casing (2), shuttle door bolt (3), spring (4) and line ball reed (5).Bobbin casing (2) and shuttle door bolt (3) are connected in shuttle main body (1) by its bobbin casing shaft coupling and shuttle door bolt pivot pin respectively, and shuttle door bolt (3) connects the location with bobbin casing (2) door bolt, and line ball reed (5) is fixedly connected on the bobbin casing (2) by screw.Shuttle main body of the present utility model (1) is the closed arc that connects string, top (1 of shuttle body (1)
-2) be straight type point, the pin slope (1 of shuttle body (1)
-1) length L is 16～22 millimeters elongated pin slope.
The utility model also is shaped on a shrinkage pool device cylindrical spiral spring (4) at the hunchbacked bottom portion of groove of shuttle main body (1) load shuttle door bolt (3), the other end of spring (4) connects shuttle door bolt (3), shuttle door bolt spring has strengthened the shuttle door bolt and has fastened the reliability that fastens bobbin casing with a bolt or latch, prevent bobbin casing and the slippage of shuttle body effectively, guaranteed the operate as normal of shuttle.
