The following is specific embodiment of the invention and with reference to accompanying drawing 1-7, technical scheme is made further to retouch
State, but the present invention is not limited to these embodiments.
One kind beats wire frame structure, includes throwing cam, and throwing cam is connected to the cam of casing by throwing cam axle
On seat 1, installing plate 2 is also included, installing plate 2 is connected with cam chair 1, and specifically, installing plate 2 is L-shaped, its horizontal part passes through spiral shell
Nail is fixed on the upper plane of cam chair 1.Set successively from the inside to the outside by the installation axle 1 with limit convex edge on installing plate 2
Upper end, spring leaf 4, the routing frame 5 of linkage are equipped with, upper end and the spring leaf 4 of linkage are relatively fixed, the connecting rod machine
Structure is rotated with spring leaf 4, and the other end of the linkage is by the installation axle 26 with limit convex edge and cam cover 7
It is hinged, the lower end of cam cover 7 is rotatably connected on the cam chair 1 of casing.The present invention can lead to when cam cover 7 is outwardly opened
Crossing linkage drives the gearing of routing frame 5 to realize automatically opening up for routing 5.Compared with step cumbersome in the prior art, significantly
Time required for reducing broken string threading, improve operating efficiency.
Specifically, bushing 8 is provided between the upper end of the linkage and spring leaf 4 makes the upper end of linkage and bullet
Reed 4 is relatively fixed.One end of bushing 8 is provided with reducing diameter part 9, and the reducing diameter part 9 is arranged in the mounting hole of linkage upper end,
The other end of bushing 8 is connected with the contact of spring leaf 4.
Further, mounting seat 10 is provided with the inwall of the bottom of the cam cover 7, the other end of linkage is hinged on
In mounting seat 10, and cam cover 7 is rotatably connected on the cam chair 1 of casing by mounting seat 10.Set because cam chair 1 is included
The cam end cap 11 at its opening is put, in order that structure more optimizes, the mounting seat 10 of cam cover 7 is to be rotatably connected on cam
On end cap 11.
Further, the mounting seat 10 of the cam cover 7 rotates connection by the installation axle 3 12 with limit convex edge
On cam end cap 11, and limit convex is provided with corrugated gasket 13 along and mounting seat 10 between, and the corrugated gasket 13 is set in this
In installation axle three.
Installation axle 1 with limit convex edge of the present invention, the installation axle 26 with limit convex edge, band limited location
The installation axle 3 12 of convex edge can select axial screw.It is of course also possible to from optical axis, one end of optical axis set jump ring or
Back-up ring etc. forms limit convex edge.
Preferably, linkage of the present invention includes connecting plate 14 and connecting rod 15, the upper end of connecting plate 14 is set
It is hinged in the upper and lower end of installation axle 1 with limit convex edge and one end of connecting rod 15, the other end of connecting rod 15 is by band limited location
The installation axle 26 of convex edge is hinged with cam cover 7.Wherein, connecting plate 14 is hinged with connecting rod 15 by axial screw.
In order that spring leaf 4 is acted together therewith under the drive of connecting plate 14, it is provided with the spring leaf 4 hemispherical
Raised 16, relevant position is provided with hemispherical groove 17 on connecting plate 14, and the hemispherical protuberances 16 of the spring leaf 4 are arranged on
Realize being relatively fixed in the hemispherical groove 17 of connecting plate 14.Certainly, spring leaf 4 can also lead to being relatively fixed for connecting plate 14
Cross spring or jump ring connection.
In addition, in order to effectively ensure the inclination angle in working order of routing frame 5, it is ensured that stitching stabilization, in the routing frame 5
Side be provided with spacer pin 18, gathering sill 19 is provided with installing plate 2, one end of spacer pin 18 is set through spring leaf 4
Can move in the gathering sill 19 and along gathering sill 19.
The present invention is also equipped with corrugated gasket 13 in the opposite side of the routing frame 5, and the corrugated gasket 13 is set in and carries
In the installation axle 1 on limit convex edge, i.e., on axial screw, and corrugated gasket 13 is spacing between limit convex edge and routing frame 5.
Set in setting corrugated gasket 13 and the installation axle 3 12 with limit convex edge in installation axle 1 with limit convex edge
The purpose for putting corrugated gasket 13 is the same, is provided to be effectively ensured the stabilization of cam cover 7 and routing frame 5 during sewing, no
Can rock.
Additionally, the top of the inwall of cam cover of the present invention 7 is provided with jump ring 20, the other end elastic connection of jump ring 20
On bayonet lock 21, bayonet lock 21 is fixed on the upper end of the cam chair 1 of casing.For optimization design, specifically, bayonet lock 21 is integrally fixed at
On the cam end cap 11 of cam chair 1.Position when bayonet lock 21 can be closed with jump ring 20 to cam cover 7 carries out spacing.
It is a further object to provide a kind of sewing machine, including one kind as described above beats wire frame structure.
Specific implementation step of the invention is：
Cam cover 7, the outside side shifting of 7 drivening rod of cam cover 15 are opened, connecting rod 15 drives connecting plate 14 to rotate counterclockwise,
Connecting plate 14 is relatively fixed with spring leaf 4, therefore by spring leaf 4 routing frame 5 can be driven to rotate counterclockwise, when 7 turns of cam cover
When dynamic about 95 degree, routing frame 5 just turns to horizontal level, facilitates threading.The motion process of closing cam cover 7 is similar.
If it is desired to adjustment throwing cam position on the premise of cam cover 7 is opened, it is necessary to put down routing frame 5.Now we
Cam cover 7 only need to be compressed, routing frame 5 is pressed downward with certain power, now acting on spring leaf 4 will separate with connecting rod 15.Routing
Frame 5 can ensure to be parked in accurate position by the position-limiting action of installing plate 14, and adjustment throwing cam is finished, and need to only close cam
Cover 7, spring leaf 4 will coordinate automatically with connecting rod 15, recover relatively-stationary state.
Specific embodiment described herein is only to the spiritual explanation for example of the present invention.Technology neck belonging to of the invention
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from spirit of the invention or surmount scope defined in appended claims.
