The utility model has the advantages of simple structure is compact, the installation is maintained conveniently and the transmission variety.
Description
Technical field
This utility model relates to the parts of a kind of industrial sewing equipment, is specifically related to lever assembly before the dual-pulling rod type of a kind of sewing machine.
Background technology
The most front lever assembly of industrial sewing machine all have employed the structure of a pull bar, 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 the most increasingly cannot meet the demand of people.
Summary of the invention
Technical problem to be solved in the utility model 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 this utility model sewing machine, 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 can be rotated rotating around respective front nose end by front nose end 21 and the front nose end 31 of short rod 3, long draw 2 and the short rod 3 of bearing pin connection long draw 2；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 this utility model can reach has the technical effect that
This utility model has the advantages such as simple and compact for structure, convenient for installation and maintenance and transmission multiformity.
Accompanying drawing explanation
Being described in further detail this utility model with detailed description of the invention below in conjunction with the accompanying drawings, those skilled in the art it is possible to be better understood by other advantages of the present utility model and effect.It should be noted that structure that the accompanying drawing of description drawn, ratio, size etc., only in order to coordinate detailed description of the invention, be better understood upon design of the present utility model 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 this utility model sewing machine, 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 front nose end 21 and the front nose end 31 of short rod 3 of long draw 2 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 be 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 domain of the present utility model is not intended that the technical scheme that any restriction, every employing equivalent or equivalent transformation are formed, all within protection domain of the present utility model.
