Abstract
The utility model discloses presser foot device in a kind of flexibility of sewing machine, including middle presser feet seat, the lower end of middle presser feet seat offers a mounting hole, and middle presser feet head is movably set with mounting hole, and middle presser feet head can move up and down along mounting hole；Presser feet seat during the lower end of middle presser feet head is stretched out, the extension of middle presser feet head are arranged with spring, and one end of spring props up the lower surface of middle presser feet seat, and the other end of spring props up middle presser feet head.For the utility model in sewing process, middle presser feet head can touch sewing all the time under the action of the spring, so as to the flexible working of presser feet in realizing；When sewing down products, drilling out for eider down in sewing can be effectively prevented.
Description
Technical field
It the utility model is related to a kind of accessaries of sewing machine, and in particular to presser foot device in a kind of flexibility of sewing machine.
Background technology
Middle presser feet is mainly used in some special sewing machine fields, such as pattern sewing machine, bar tacking machine, template machine etc., is a kind of
Very important moving component on sewing machine.Middle presser feet is to realize and move up and down have with eedle by motor or mechanical cam driving
Certain synchronized relation.Presser feet may proceed to push down sewing in when eedle leaves sewing, when eedle rises to certain altitude in press
Pin ensures the formation of stitching further out sewing.The long time risen is more early later on presser feet in when sewing down products
Rise, the eider down in sewing is easier to be taken out of outside fabric by suture；But middle presser feet rises too late, when sewing starts to move
When do not have also rising to hold sewing, influence sewing efficiency.
The content of the invention
Technical problem to be solved in the utility model is to provide presser foot device in a kind of flexibility of sewing machine, and it can be
Eedle continues to keep certain pressure to sewing when leaving sewing.
In order to solve the above technical problems, the technical solution of presser foot device is in the flexibility of the utility model sewing machine：
Including middle presser feet seat 1, the lower end of middle presser feet seat 1 offers a mounting hole, and middle presser feet is movably set with mounting hole
First 2, middle presser feet first 2 can move up and down along mounting hole；Presser feet seat 1 during the lower end of middle presser feet first 2 is stretched out, middle presser feet first 2 are stretched
Go out portion and be arranged with spring 3, one end of spring 3 props up the lower surface of middle presser feet seat 1, and the other end of spring 3 props up middle presser feet first 2.
Medium pressure pin first 2 is engaged with the mounting hole of middle presser feet seat 1.
The upper end external diameter of medium pressure pin first 2 is more than the diameter of mounting hole.
What the utility model can reach has the technical effect that：
For the utility model in sewing process, middle presser feet head can touch sewing all the time under the action of the spring, so as to real
The flexible working of presser feet in existing；When sewing down products, drilling out for eider down in sewing can be effectively prevented.
The utility model is simple in construction, and anti-chiseling down positive effect, cost is relatively low, and presser feet changes convenient, use value
It is higher.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Fig. 1 be the utility model sewing machine flexibility in presser foot device schematic diagram；
Fig. 2 is the working state schematic representation that middle presser feet seat of the present utility model pushes；
Fig. 3 is the working state schematic representation lifted on middle presser feet seat of the present utility model.
Description of reference numerals in figure：
1 is middle presser feet seat, and 2 be middle presser feet head,
3 be spring.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
The accompanying drawing of type embodiment, the technical scheme of the utility model embodiment is clearly and completely described.Obviously, it is described
Embodiment is part of the embodiment of the present utility model, rather than whole embodiments.Based on described of the present utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained on the premise of without creative work, all belongs to
In the scope of the utility model protection.Unless otherwise defined, technical term or scientific terminology used herein should be this reality
With the ordinary meaning that there is the personage of general technical ability to be understood in new art." comprising " used herein etc. is similar
The element that word means to occur before the word either cover the element for appearing in the word presented hereinafter or object and its wait by object
Together, other elements or object are not excluded for.
As shown in figure 1, presser foot device in the flexibility of the utility model sewing machine, including middle presser feet seat 1, middle presser feet seat 1
Lower end offers a mounting hole, and middle presser feet first 2 is movably set with mounting hole；
Middle presser feet first 2 is engaged with the mounting hole of middle presser feet seat 1, can be transported up and down along mounting hole after middle first 2 stress of presser feet
It is dynamic；
Presser feet seat 1 during the lower end of middle presser feet first 2 is stretched out, the extension of middle presser feet first 2 are arranged with spring 3, one end of spring 3
The lower surface of middle presser feet seat 1 is propped up, the other end of spring 3 props up middle presser feet first 2.
After middle presser feet first 2 is attached in mounting hole, the upper end of centering presser feet first 2 carries out riveting side PROCESS FOR TREATMENT, so that in
The upper end external diameter of presser feet first 2 is more than the diameter of mounting hole, to ensure middle presser feet first 2 during up and down motion without departing from
Presser feet seat 1.
Operation principle of the present utility model is as follows：
Sewing machine first pushes middle presser feet seat 1 in sewing process, and middle presser feet first 2 falls and touch sewing therewith；
In the case where middle presser feet first 2 is in falling state, middle presser feet seat 1 is set to be moved up and down together with eedle；When eedle is downward
Motion penetrate sewing, when middle presser feet seat 1 pushes, middle presser feet first 2 by sewing reaction force along mounting hole relative to middle presser feet seat 1
Motion upwards, so that spring 3 compresses to form spring force, as shown in Figure 2；When eedle travels upward and out sewing, middle presser feet
When being lifted on seat 1, the release spring power of spring 3 acts on middle presser feet first 2, middle presser feet first 2 is still within pressed status（I.e. middle presser feet
Seat 1 moves up and middle presser feet first 2 remains stationary as）, as shown in figure 3, so that middle presser feet first 2 remains in that the state for touching sewing.
Although embodiment of the present utility model is hereinbefore described in detail, come for those skilled in the art
Say it is readily apparent that various modifications and variations can be carried out to these embodiments.However, it is understood that this modification and change
Change is belonged within the scope of the utility model and spirit described in claims.Moreover, described herein practicality is new
Type can have other embodiments, and can be practiced or carried out in several ways.
