Abstract
The invention relates to a swinging crank for a needle bar of an industrial sewing machine and belongs to the field of machinery. The swinging crank comprises a crank base (3) and a fixed base (2) which are connected through a connecting rod (1), wherein a fixed hole (4) is arranged on the fixed base (2); the fixed base (2) comprises a needle bar hole (5) and a pillar hole (6); a gap hole (7) is arranged on the crank base (3); and the gap hole (7) extends to the outer end of the crank base (3) from an inner circle of the needle bar hole (5) and vertically passes through the pillar hole (6). The swinging crank for the needle bar of the industrial sewing machine is reasonable in structure design; the swinging crank for the needle bar is firmer; the swinging crank for the needle bar is more compactly mounted with equipment; and the fault generated during the running process of the industrial sewing machine is reduced.
Description
Technical field
The present invention relates to a kind of shank wobble crank that is used for industrial sewing machine, belong to mechanical field.
Background technology
At present; Shank wobble crank of the prior art is unreasonable owing to structure is provided with, and when the production of industrial sewing machine, can break down, and its reason is because shank wobble crank and shank are installed not tight; Cause shank when swing loosening, thereby produce fault when causing the industrial sewing machine operation.
Summary of the invention
To above deficiency, the invention provides a kind of shank wobble 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 shank wobble crank that is used for industrial sewing machine comprises crank base (3) and holder (2), and said crank base (3) is connected through connecting rod (1) with holder (2); Said holder (2) is provided with a fixing hole (4); Said crank base (2) comprises a needle bar hole (5) and a post hole (6); Hole, a slit (7) also is set on the said crank base (3); Hole, said slit (7) extends to the outer end of crank base (3) from the interior ring of needle bar hole (5), and vertically passes post hole (6).
Said fixing hole (4) is fixed through screw thread.
By technique scheme, the present invention has advantage at least:
Reasonable in design of the present invention, the shank wobble crank is more firm, and it is tightr to make shank wobble crank and equipment install, the fault that has produced 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 shank wobble crank that is used for industrial sewing machine comprises crank base 3 and holder 2, and said crank base 3 is connected through connecting rod 1 with holder 2; Said holder 2 is provided with a fixing hole 4; Said crank base 2 comprises a needle bar hole 5 and a post hole 6; Hole, a slit 7 also is set on the said crank base 3, and hole 7, said slit extends to the outer end of crank base 3 from the interior ring of needle bar hole 5, and vertically passes post hole 6.
Said fixing hole 4 is fixed through screw thread.
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.
