Abstract
The invention discloses a double-pull-rod type front lever assembly of a sewing machine. The double-pull-rod type front lever assembly comprises a front lever, wherein an axial position hole is formed in the front lever; the front lever can swing by taking the axial position hole as a swinging center; a swinging end of the front lever is connected with a front hole end of a long pull rod and a front hole end of a short pull rod through pin shafts; the long pull rod and the short pull rod can rotate around the respective front hole ends respectively; a rear hole end of the long pull rod is connected with a transmission part; and a rear hole end of the short pull rod is connected with a rear lever. The double-pull-rod type front lever assembly of the sewing machine has the advantages of simple and compact structure, convenience for installation and maintenance, diversity in transmission and the like.
Description
Technical field
The present invention relates to the parts of a kind of industrial sewing equipment, be specifically related to lever assembly before the dual-pulling rod type of a kind of sewing machine.
Background technology
The front lever assembly of industrial sewing machine all have employed the structure of a pull bar mostly at present, by pull bar, front lever and rear lever is linked together, it is achieved the linkage of transmission, can only realize a kind of kind of drive in this case.And the automatization of sewing machine and the multiformity etc. of operator scheme are required more and more by people now, the drive mechanism of single formula also increasingly cannot meet the demand of people.
Summary of the invention
The technical problem to be solved is to provide lever assembly before the dual-pulling rod type of a kind of sewing machine, and it can solution problem above lighter, convenient.
For solving above-mentioned technical problem, before the dual-pulling rod type of sewing machine of the present invention, the technical solution of lever assembly is:
Including front lever 1, front lever 1 offers a hole, axle position 11, and front lever 1 can swing with hole, axle position 11 for the centre of gyration；The swinging end of front lever 1 connects the front nose end 21 of long draw 2 and the front nose end 31 of short rod 3 by bearing pin, and long draw 2 and short rod 3 can rotate rotating around respective front nose end；The rear nose end 22 of long draw 2 is connected with drive disk assembly, and the rear nose end 32 of short rod 3 is connected with rear lever 5.
The front nose end 21 of described long draw 2 is sheathed on bearing pin jointly with the front nose end 31 of short rod 3, is separated by jump ring 4 between front nose end 21 and the front nose end 31 of short rod 3 of long draw 2.
The front nose end 21 of described long draw 2 is circular hole, and the rear nose end 22 of long draw 2 is long groove shape.
The front nose end 31 of described short rod 3 is circular hole, and the rear nose end 32 of short rod 3 is circular hole or long groove shape.
The middle part of described long draw 2 is formed with bending part.
When the rear nose end 22 that drive disk assembly drives described long draw 2 swings around its front nose end 21, it is possible to before driving, lever 1 swings simultaneously；Or, when rear lever 5 swings, drive front lever 1 to swing by short rod 3, and drive long draw 2 to move.
What the present invention can reach has the technical effect that
The present invention has the advantages such as simple and compact for structure, convenient for installation and maintenance and transmission multiformity.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation, and those skilled in the art it is possible to be better understood by other advantages of the present invention and effect.It should be noted that structure that the accompanying drawing of description draws, ratio, size etc., only in order to coordinate detailed description of the invention, be better understood upon the design of the present invention for those skilled in the art.

Detailed description of the invention
As shown in Figure 1 to Figure 3, lever assembly before the dual-pulling rod type of sewing machine of the present invention, including front lever 1, the middle part of front lever 1 offers a hole, axle position 11, and front lever 1 is connected in casing 100 by hole 11, axle position axle and can swing flexibly for the centre of gyration with hole, axle position 11；
A wherein swinging end of front lever 1 connects the front nose end 21 of long draw 2 and the front nose end 31 of short rod 3 by bearing pin, the front nose end 21 of long draw 2 is sheathed on bearing pin jointly with the front nose end 31 of short rod 3, and is separated by jump ring 4 between the front nose end 21 of long draw 2 and the front nose end 31 of short rod 3；Long draw 2 and short rod 3 can rotating around respective front nose end flexible rotatings；
The rear nose end 22 of long draw 2 is connected with drive disk assembly, and the rear nose end 32 of short rod 3 is connected with rear lever 5.
The front nose end 21 of long draw 2 is circular hole, and the rear nose end 22 of long draw 2 is long groove shape.
The front nose end 31 of short rod 3 is circular hole, and the rear nose end 32 of short rod 3 is circular hole or long groove shape.
The middle part of long draw 2 is formed with bending part.
When the rear nose end 22 that drive disk assembly drives long draw 2 swings around its front nose end 21, it is possible to before driving, lever 1 swings simultaneously；
Or, when rear lever 5 swings, drive front lever 1 to swing by short rod 3, and drive long draw 2 to move.
Above is embodied as example, protection scope of the present invention being not intended that, any restriction, every employing are equal to replacement or the technical scheme of equivalent transformation formation, all within protection scope of the present invention.
