Abstract

The invention relates to a reverse crank for an industrial sewing machine, and belongs to the field of machines. The reverse crank comprises a reverse crank body, wherein the reverse crank body comprises a first crank hole (1) and a second crank hole (2); a first boss (3) is arranged on the upper part of the first crank hole (1); two first column holes (5) are formed in the first boss (3); a second boss (4) is arranged on the upper part of the second crank hole (2); and a second column hole (6) is formed in the second boss (4). The reverse crank is reasonable in structural design, firm and tight in the installation with equipment, and the failure generated during the running of the industrial sewing machine is reduced.

Description

A kind of counter-rotating crank for industrial sewing machine
Technical field
The present invention relates to a kind of counter-rotating crank for industrial sewing machine, belong to mechanical field.
Background technology
At present, counter-rotating crank of the prior art is unreasonable owing to structure arranges, and can break down when the production of industrial sewing machine, and its reason is because the installation of counter-rotating crank is not tight, and is loosening when causing crank-swinging, thereby produces fault when causing industrial sewing machine to move.
Summary of the invention
For above deficiency, the invention provides a kind of counter-rotating crank that is used for industrial sewing machine of new structure.
Main technical content of the present invention is as follows: a kind of counter-rotating crank for industrial sewing machine, comprise a counter-rotating crank body, described body comprises the first crank hole (1) and the second crank hole (2), described the first crank hole (1) top arranges first boss (3), two the first post holes (5) are set on described the first boss (3), described the second crank hole (2) top arranges second boss (4), and second a post hole (6) is set on described the second boss (4).
Above-mentioned the first post hole (5) is perpendicular to the first crank hole (1), and communicates with it.
Above-mentioned the second post hole (6) is perpendicular to the second crank hole (2), and communicates with it.
By technique scheme, the present invention has following advantages at least: reasonable in design of the present invention, and the counter-rotating crank is more firm, and so that counter-rotating crank and equipment installation are tightr, the fault that has produced when having reduced the industrial sewing machine operation.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is 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, its specific embodiment, structure, feature and effect thereof to foundation the present invention proposes are described in detail as follows.
As shown in Figure 1, a kind of counter-rotating crank for industrial sewing machine, comprise a counter-rotating crank body, described body comprises the first crank hole 1 and the second crank hole 2, described the first crank hole 1 top arranges first boss 3, two the first post holes 5 are set on described the first boss 3, and described the second crank hole 2 tops arrange second boss 4, and second a post hole 6 is set on described the second boss 4.
Above-mentioned the first post hole 5 is perpendicular to the first crank hole 1, and communicates with it.
Above-mentioned the second post hole 6 is perpendicular to the second crank hole 2, and communicates with it.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet be not to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement 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 solution of the present invention, any simple modification that foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
