Abstract

The utility model relates to a sewing machine and discloses a single-thread circular seam sewing machine. The single-thread circular seam sewing machine comprises a lower shaft (1) and an upper shaft (2) which are connected with each other by a vertical shaft (3), and the speed ratio of the lower shaft (1) to the upper shaft (2) is 1 to 1. According to the single-thread circular seam sewing machine, the upper shaft and the lower shaft of the sewing machine are set to rotate at the same speed, so that the failure rate of the equipment is reduced, the sewing efficiency is improved, and meanwhile, the single-thread circular seam sewing machine has the advantages of rapidness and convenience in maintenance.

Description

The single line ring seam sewing machine

Technical field

The utility model relates to Sewing machines, has related in particular to a kind of single line ring seam sewing machine.

Background technology

At present, the ring seam sewing machine on the market adopts two-wire more, complex structure, fault rate height, and, caused the running speed of Sewing machines low by axle is different with the rotating speed of lower shaft on it, sewing efficiency is low.

Summary of the invention

The utility model is to the complex structure of single line ring seam sewing machine in the prior art, and shortcomings such as fault rate height provide a kind of lower shaft of going up to turn round with speed, and it is fast to have machine run speed, the single line ring seam sewing machine of sewing efficiency advantages of higher.

In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:

The single line ring seam sewing machine comprises lower shaft and last axle, is connected through vertical pivot between described lower shaft and the last axle, and the rotating ratio between lower shaft and last is 1:1.

As preferably, be connected through angular wheel between described vertical pivot and the lower shaft, be connected through angular wheel between vertical pivot and the last axle.

As preferably, described lower shaft is provided with crochet hook.

As preferably, described single line ring seam sewing machine also comprises shank, is connected through crank between shank and the last axle, is provided with jockey between last and the shank.

The utility model is owing to adopted above technical scheme, and have significant technique effect: the utility model is set to same rotating speed through the last lower shaft of Sewing machines, has reduced rate of breakdown, has improved sewing efficiency, has simultaneously and keeps in repair advantage fast and easily.

Description of drawings

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

The toponym that each number designation referred in the above accompanying drawing is following: wherein 1-go up axle, 2-lower shaft, 3-vertical pivot, 4-jockey, 5-shank, 6-crochet hook.

The specific embodiment

The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1:

Embodiment 1

The single line ring seam sewing machine, as shown in Figure 1, comprise lower shaft 1 and last axle 2, be connected through vertical pivot 3 between described lower shaft 1 and the last axle 2, the rotating ratio between lower shaft 1 and last 2 is 1:1.Because lower shaft 1 adopts the rotating speed of 1:1 with last axle 2, so compares with existing ring seam sewing machine, machine run speed is faster, and sewing efficiency is higher.

Be connected through angular wheel between vertical pivot 3 and the lower shaft 1, be connected through angular wheel between vertical pivot 3 and the last axle 2.Lower shaft 1 is provided with crochet hook 6.

The single line ring seam sewing machine also comprises shank 5, is connected through crank between shank 5 and the last axle 2, is provided with jockey 4 between last 2 and the shank 5.Between lower shaft 1 and the vertical pivot 3, be in transmission connection through angular wheel between last axle 2 and the vertical pivot 3.

In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
