Abstract
The invention relates to a needle bar crank for an industrial sewing machine and belongs to the field of machinery. The needle bar crank comprises a body, the body comprises a base and a hollow cylinder (3), wherein the base is formed by a sectorial base part (1) and a quadrilateral base part (2), the hollow cylinder (3) is perpendicular to the base and used for holding a needle bar, and a fixed hole (22) and a mounting hole (21) are arranged on the quadrilateral base part. The needle bar crank for the industrial sewing machine is reasonable in structure design, firmer, tighter in mounting with the needle bar, and capable of reducing fault generated during running.
Description
Technical field
The present invention relates to a kind of needle bar crank that is used for industrial sewing machine, belong to mechanical field.
Background technology
At present, needle bar crank of the prior art is unreasonable owing to structure is provided with, and when the industrial sewing machine feeding, can break down, and its reason is because needle bar crank is not tight with being connected of shank, causes shank loosening, produces fault when producing thereby cause.
Summary of the invention
To above deficiency, the invention provides a kind of needle bar 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 needle bar crank that is used for industrial sewing machine; Comprise a body; Body comprises the base that a fan-shaped base (1) and a quadrangle base (2) are formed; Also comprise a hollow cylinder perpendicular to base (3), said hollow cylinder is used to place shank, and a fixing hole (22) and an installing hole (21) are set on the said quadrangle base.
Said fixing hole (22) is to fix through screw thread.
Come round with installing hole (21) is vertical in said fixing hole (22).
By technique scheme, the present invention has advantage at least:
Reasonable in design of the present invention, needle bar crank is more firm, and makes that the installation of needle bar crank and shank is tightr, the fault that has produced when having reduced 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 needle bar crank that is used for industrial sewing machine; Comprise a body, body comprises a fan-shaped base 1 and the base that quadrangle base 2 is formed, and also comprises a hollow cylinder 3 perpendicular to base; Said hollow cylinder is used to place shank, and a fixing hole 22 and an installing hole 21 are set on the said quadrangle base.
Said fixing hole 22 is to fix through screw thread.
Said fixing hole 22 and installing hole 21 are vertically to come round.
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.
