Abstract
The utility model relates to sewing machine technique field, especially the sky flat structure of Sewing machines is related to, include sewing machine case and shank, an additional balance holder on sewing machine case, on balance holder, group is provided with the gentle tension disk in sky, balance is positioned at above shank, and balance swings up and down center and shank center is in the same center line; Described balance is driven by a crank and swings up and down, and crank is arranged on balance holder, is connected with drive coordination belt wheel by rotating shaft.The utility model adds a suite handle, balance, wire extender structure on the basis of original casing, upper thread directly crosses line from installing balance additional, and balance swings up and down center and shank center and is in the same center line, test through reality, cross linear pressure less than the balance positional structure of transmission Sewing machines, cross line more smooth and easy, the adjustment for upper thread bottom line is more simple and convenient; Sewing circuit is attractive in appearance, promotes sewing quality.
Description
Technical field
The utility model relates to sewing machine technique field, especially relates to the sky flat structure of Sewing machines.
Background technology
Traditional sewing mechanism generally comprises upper casing and lower casing, be installed in the upper spindle motor on upper casing and needle bar mechanism, be located in the upper axle be in transmission connection with upper spindle motor and needle bar mechanism respectively in upper casing, and the lower spindle motor be installed on lower casing and shuttle race mechanism, be located in the lower shaft be also in transmission connection with lower spindle motor and shuttle race respectively in lower casing to form, upper axle is driven to rotate by upper spindle motor, upper axle drives needle bar mechanism to move up and down the sewing action up and down realizing sewing needle, lower shaft is driven to rotate by lower spindle motor, this lower shaft drives shuttle race mechanism kinematic to carry out sewing operation to coordinate sewing needle.During sewing, upper thread must pass from shank inside, balance and the tension disk part of existing Sewing machines are installed on casing traditional location, balance minimum point is lower than plane on shank, must the synchronous knee-action principle that could normally work according to needle bar of sewing machine and balance, upper thread to have to pass through after balance and tension disk after three-sixth turn from shank inside out.Therefore cross linear pressure very large, the tension force of upper thread bottom line is difficult to regulate, and sewing circuit unsightly, easily causes and throws the series of problems such as upper thread bottom line, rotten line, circuit be not straight.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect of the prior art, provides that a kind of to cross linear pressure less than the balance positional structure of transmission Sewing machines, crosses line more smooth and easy, for the sky flat structure of the adjustment Sewing machines more simply and easily of upper thread bottom line.
For achieving the above object, the utility model adopts following technical scheme:
The sky flat structure of Sewing machines, include sewing machine case and shank, an additional balance holder on sewing machine case, on balance holder, group is provided with the gentle tension disk in sky, balance is positioned at above shank, and balance swings up and down center and shank center is in the same center line.
Described balance is driven by a crank and swings up and down, and crank is arranged on balance holder, is connected with drive coordination belt wheel by rotating shaft.
The eccentric hinged eccentric ratio of described crank, the eccentric ratio other end is then articulated with on balance stage casing, and one end opposing with crossing line end of balance is hinged on sewing machine case.
The utility model adds a suite handle, balance, wire extender structure on the basis of original casing, upper thread directly crosses line from installing balance additional, and balance swings up and down center and shank center and is in the same center line, test through reality, cross linear pressure less than the balance positional structure of transmission Sewing machines, cross line more smooth and easy, the adjustment for upper thread bottom line is more simple and convenient; Sewing circuit is attractive in appearance, promotes sewing quality.
accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the utility model preferred embodiment;
Accompanying drawing 2 is the side view of Fig. 1 embodiment.
detailed description of the invention:
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Consult shown in Fig. 1,2, it is preferred embodiment schematic diagram of the present utility model, the utility model is about a kind of sky flat structure of Sewing machines, include sewing machine case 1 and shank 2, an additional balance holder 3 on sewing machine case 1, on balance holder 3, group is provided with balance 4 and tension disk 5, and balance 4 is positioned at above shank 2, and balance 4 swings up and down center and shank 2 center is in the same center line.During use, upper thread directly crosses line from the balance 4 that installs additional, and this balance 4 swings up and down center and shank 2 center is in the same center line, test through reality, cross linear pressure less than the balance positional structure of transmission Sewing machines, cross line more smooth and easy, the adjustment for upper thread bottom line is more simple and convenient; Sewing circuit is attractive in appearance, promotes sewing quality.
Shown in Fig. 1,2, in the present embodiment, described balance 4 is driven by a crank 6 and swings up and down, and crank 6 is arranged on balance holder 3, is connected with drive coordination belt wheel 7 by rotating shaft.Drive coordination belt wheel 7 connects the balance transmission mechanism of original Sewing machines by Timing Belt, thus obtains synchronous effect.In figure, the eccentric hinged eccentric ratio 8 of crank 6, eccentric ratio 8 other end is then articulated with on balance 4 stage casing, and one end opposing with crossing line end of balance 4 is hinged on sewing machine case 1.Structure is simple, scientific and reasonable, stable action, crosses linear pressure less, and cross line more smooth and easy, precision is high, the operation ratio of significant increase Sewing machines and operability, meets industry and utilizes.
Certainly; more than in conjunction with embodiment, the utility model is elaborated; only for technical conceive of the present utility model and feature are described; its object is to allow person skilled in the art understand content of the present utility model and to be implemented; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
