Abstract
The invention relates to a lower looper shaft crank for an industrial sewing machine and belongs to the field of machinery. The lower looper shaft crank comprises a connecting rod (1), a fixed hoop (5) is arranged at one end of the connecting rod (1), two needle shafts (2) are arranged at the other end of the connecting rod (1), each of the needle shaft (2) is provided with a needle shaft hole (3), the fixing hoop (5) is provided with a hole seam (7), two fixed holes (8) are arranged on two sides of the fixing hoop (5) and used for fixing the fixing hoop (5). The lower looper shaft crank for the industrial sewing machine is reasonable in structure design, firmer, tighter in mounting with equipment, and capable of reducing fault generated during running of the industrial sewing machine.
Description
Technical field
The present invention relates to a kind of following curved needle shaft crank that is used for industrial sewing machine, belong to mechanical field.
Background technology
At present, down curved needle shaft crank of the prior art can break down when the production of industrial sewing machine because structural design is unreasonable, its reason be since down the curved needle shaft crank install not tight, thereby produce fault when causing the industrial sewing machine operation.
Summary of the invention
To above deficiency, the invention provides a kind of following curved needle shaft crank that is used for industrial sewing machine of new structure.
Major technique of the present invention thes contents are as follows:
A kind of following curved needle shaft crank that is used for industrial sewing machine; Comprise connecting rod (1), an end of said connecting rod (1) is provided with a clips (5), and the other end of said connecting rod (1) is provided with two needle shafts (2); A needle shaft hole (3) all is set on the said needle shaft (2); A hole seam (7) is set on the said clips (5), and the both sides of said clips (5) are provided with fixing hole (8), are used for fixing clips (5).
Be symmetrical set two grooves (4) on (1) two face of above-mentioned connecting rod.
By technique scheme, the present invention has advantage at least:
Reasonable in design of the present invention, following curved needle shaft crank is more firm, and it is tightr to make down curved needle shaft crank and equipment install, the fault of generation when having reduced the industrial sewing machine operation.
The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment, structure, characteristic and the effect thereof that proposes according to the present invention, specify as after.
As shown in Figure 1, a kind of following curved needle shaft crank that is used for industrial sewing machine comprises connecting rod 1; One end of said connecting rod 1 is provided with a clips 5; The other end of said connecting rod 1 is provided with two needle shafts 2, and a needle shaft hole 3 all is set on the said needle shaft 2, and a hole seam 7 is set on the said clips 5; The both sides of said clips 5 are provided with fixing hole 8, are used for fixing clips 5.
Be symmetrical set two grooves 4 on 1 two faces of above-mentioned connecting rod.
The above only is preferred embodiment of the present invention, is not the present invention is done any pro forma restriction; Though the present invention discloses as above with preferred embodiment; Yet be not in order to limiting the present invention, anyly be familiar with the professional and technical personnel, in not breaking away from technical scheme scope of the present invention; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be the content that does not break away from technical scheme of the present invention, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical scheme of the present invention according to technical spirit of the present invention.
