Abstract

The utility model relates to a reverse rotation crank for an industrial sewing machine and belongs to the field of machinery. The reverse rotation crank comprises a reverse rotation crank body which is provided with a first crank hole (1) and a second crank hole (2). The upper portion of the first crank hole (1) is provided with a first boss (3). The first boss (3) is provided with two first column holes (5). The upper portion of the second crank hole (2) is provided with a second boss (4). The second boss (4) is provided with a second column hole (6). The reverse rotation crank for the industrial sewing machine is reasonable in structural design, firmer, and more compact in installation with equipment, and reduces failures during running of the industrial sewing machine.

Description

A kind of counter-rotating crank for industrial sewing machine

Technical field

The utility model relates to a kind of counter-rotating crank for industrial sewing machine, belongs 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.

The utility model content

For above deficiency, the utility model provides a kind of counter-rotating crank that is used for industrial sewing machine of new structure.

Main technical content of the present utility model 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 utility model has following advantages at least: the utility model reasonable in design, 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 utility model is provided in detail by following examples and accompanying drawing thereof.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Be to reach technological means and the effect that predetermined utility model purpose is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to according to its specific embodiment, structure, feature and the effect thereof that the utility model proposes, be 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 utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model 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 solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
