Existing two-needle sewing machine shank Switch structure as shown in Figure 1 to Figure 3, in fuselage 40 fronts arresting lever 41 is set, the top of arresting lever 41 and fuselage 40 are hinged, arresting lever 41 can be around the hinge point activity, arresting lever 41 fronts are provided with shank location-plate 42, the back is provided with push pedal 43, and the axial region of arresting lever 41 passes fuselage 40 and links to each other with the lever shaft arm 44 at the back side.The switching mechanism structure is made up of cross bar 5, back-moving spring 6, collar 7, spring 8, pole 9 and slide block 10 etc. as shown in Figure 3; Connecting rod 4 upper ends and lever shaft arm 44 flexibly connect, and cross bar 5 left ends and connecting rod 4 lower ends are hinged, and cross bar 5 is provided with three collars 7, and back-moving spring 6, spring 8 are enclosed within on the cross bar 5; One end of pole 9 and spring 8 are conflicted, and the other end is connected with slide block 10.
Left shank is decommissioned, and the arresting lever 41 that need turn left is to the left-hand end of shank location-plate 42, and arresting lever 41 drives lever shaft arms 44 towards counterclockwise moving, and connecting rod 4 drives cross bars 5 and moves right, and slides towards institute's b direction shown in Figure 3 thereby drive slide block 10.Depress push pedal 43, arresting lever 41 is subjected to the effect of the back-moving spring 6 in the switching mechanism and gets back to the centre position, and slide block 10 slides in the other direction and gets back to the origin-location.
Above-mentioned crosspointer bar switches need be with pulling arresting lever about hand, resetting to press down push pedal, because crosspointer bar switching device shifter syndeton complexity often needs firmly could switch, increased labor intensity of operating personnel; The switching device shifter installation site is higher than Sewing machines work face, and operating personnel's operation of need raising one's hand is cumbersome, influences operating efficiency.
The utility model content:
The purpose of this utility model provides a kind of crosspointer bar change-over switch easy to use, simple to operate and the corner seam sewing machine that can increase work efficiency and puts.
Scheme of the present utility model is: comprise the connecting rod that is hinged with the cross bar of switching mechanism, small end flexibly connects with cylinder piston rod, and the connecting rod middle part is by screw and fuselage hinge, and the cylinder piston both sides are shaped on blow vent.
The blow vent of cylinder is connected with controller by breather pipe, and controller is established left button, right button and X button.
The utility model has the advantages that: adopt the controller control cylinder to drive switching mechanism and operate the crosspointer pin, the user only needs the button of flicking controller to get final product, and is simple to operate, reduces labour intensity; The optional position of Sewing machines can be placed or be installed in to controller, and the operator is adjusted to the most suitable position as required, do not need to raise one's hand and just can operate, easy to use, improved operating efficiency.

The specific embodiment:
With reference to Fig. 4 to Fig. 6, change-over switch of the present utility model utilizes cylinder 1 to realize, connecting rod 4 upper ends and piston rod flexibly connect, and connecting rod 4 middle parts are hinged by screw and fuselage 40, and lower end and cross bar 5 flexibly connect.The piston two ends of cylinder 1 respectively are shaped on blow vent 2,3, and the breather pipe that passes through of blow vent 2,3 is connected with controller.Controller is established left button 30, right button 31 and X button 32.The air inlet of left button 30 control blow vents 2, the air inlet of right button 31 control blow vents 3, X button 32 can be discharged the gases at high pressure of blow vent 2,3.
Press left button 30, blow vent 2 injects pressure-air, the piston of cylinder 1 drives motion bar and is moved to the left, connecting rod 4 upper ends are moved to the left, because the centre of connecting rod 4 and fuselage 40 are hinged, the lower end moves right around hinge point, by cross bar 5, pole 9, slide block 10 moves towards right, and left shank 13 is quit work.
The switch operating principle is as follows: with reference to Fig. 7 to Figure 11, slide block 10 slides left.Be fixed on shank 12,13 on the needle bar bracket install to can clutch 15 li on shank folder, shank folder 15 is along with drive link 14 moves up and down.After near shank folder 15 rises to top dead-centre, the switching controls bar 16 in left side that is contained in 15 li on shank folder is towards institute's c direction rotation shown in Figure 10 and run into the jut of slide block 10.With after the equipped mutually clutch-plate 17 of switching controls bar 16 moves towards the d direction and the shank clutch-plate 17 that is in mated condition break away from from shank, shank just can't be up and down.In order to keep the disengaged position of clutch-plate 17, embed retention tab 19.In order to prevent that clutch-plate breaks away from the free-falling of back shank 13, the locking plate 20 that is assembled on the needle bar bracket is embedded in the groove of shank 13 upsides, it is parked near the top dead-centre, left shank 13 quits work.
When left shank 13 is in halted state, press X button 32, blow vent 2 is drained gas, under the effect of back-moving spring 6, piston reset, connecting rod 4 is subjected to resetting under the effect of the back-moving spring 6 in the switching mechanism, and slide block 10 is got back to middle position towards left to slide protrusion portion, position as shown in Figure 9.When being in this state, shank folder 15 rises.The releasing pin 18 of dress is collided with slide block 10 in top dead-centre vicinity shank folder 15.Remove pin 18 retention tab 19 is depressed, its is broken away from from the groove of clutch-plate 17.After retention tab 19 broke away from, clutch-plate 17 moved towards e direction shown in Figure 11 under the effect of spring 22, embedded in the groove of shank 13 downsides.After in the groove of the downside of clutch-plate 17 embedding shanks 13, depress an end of the shank control lever 23 that is assembled on the shank 13, the other end rises locking plate 20 is broken away from from the groove of the upside of shank 13.Locking plate 20 has been subjected to the active force of spring 21, and is very weak because spring 21 and spring 22 are compared active force, so locking plate 20 is easy to just break away from.Under each embedding state of clutch-plate 17, shank 12,13 is activated the driving of connecting rod 14 and is up and down.
Right button 31 can be controlled the work of right shank, its operation principle and above-mentioned identical.
The utility model adopts cylinder to replace original change-over switch, and is simple to operate; Controller is connected with cylinder by breather pipe, and the optional position of Sewing machines can be installed or be placed on to controller, and the operator can lay according to own needs, switches conveniently, quick, increases work efficiency.
