Abstract
The invention discloses a down-proof sewing machine intermediate presser mechanism, comprising a sewing machine head. The inner side of the sewing machine head is provided with an installing groove. A compressor arm lifting sub is installed in the installing groove. The compressor arm lifting sub is installed with the upper end of a compressor arm upper segment through a first screw. A compressor arm lower segment passes through the inner side of the compressor arm upper segment. A spring is arranged between the inner surface of the compressor arm upper segment and the outer surface of the compressor arm lower segment. The compressor arm lower segment is provided with a locking nut on the outer side of the top of the compressor arm upper segment. The lower end of the compressor arm lower segment is provided with an intermediate presser through a second screw. The periphery of the installation sites of the compressor arm upper segment and the compressor arm lower segment is provided with a compression bar sleeve. Using the down-proof sewing machine intermediate presser mechanism, when a machine needle leaves a sewing material, the intermediate presser continuously keeps certain pressure on the sewing material under action of the spring, and the intermediate presser would not take away the sewing material when the intermediate presser abuts against the sewing material. The down-proof sewing machine intermediate presser mechanism is simple in structure, and down-proof effect is obvious, and use value is relatively high.

Background technology
One or more sewing thread used by Sewing machines, and sewing is formed one or more stitchings, makes the machine that one or more layers sewing interweaves or unites by a seam.Sewing function makes the goods such as the fabrics such as cotton, fiber crops, silk, hair, artificial fibre and leather, plastics, paper, and the stitching neat appearance of stitching out, firmly smooth, sewing velocity is fast, easy to use; General Sewing machines is all made up of head, support, transmission and annex four part; Head is the major part of Sewing machines; It forms by stinging material, hook line, take-up, feeding four mechanisms and coiling, binder, Luo Yadeng auxiliary body, and the motion of each mechanism reasonably coordinates, and periodic duty unites by a seam sewing; In existing Sewing machines presser foot when eedle leaves sewing in presser feet and then also to leave sewing, easily cause brill suede.
Summary of the invention
For solving the problem, the present invention proposes a kind of middle foot pressing mechanism of sewing machine of anti-chiseling down, in when eedle leaves sewing, presser feet continues to keep certain pressure to sewing under the action of the spring.
The middle foot pressing mechanism of sewing machine of anti-chiseling down of the present invention, comprises head of sewing machine, is provided with mounting groove inside described head of sewing machine, is provided with compressor arm lifting sub in described mounting groove; Described compressor arm lifting sub is installed by the first screw and compressor arm saving upper end; Described compressor arm runs through inside joint under having compressor arm and save; Save under described compressor arm saving inner surface and compressor arm between outer surface and spring is installed; Save under described compressor arm and on compressor arm, save top outer rotating-proof nut is installed; Save lower end under described compressor arm, by the second screw, middle presser feet is installed; Described compressor arm saves and saves periphery, installation position under compressor arm and one depression bar cover is installed.In when eedle leaves sewing, presser feet continues to keep certain pressure to sewing under the action of the spring; Compressor arm saves under being divided on compressor arm joint and compressor arm, and the elasticity that phase mutual is certain, makes middle presser feet can not take away sewing when touching sewing; Its structure is simple, and anti-chiseling down successful, cost is lower, and use value is higher.
As preferred embodiment, on described compressor arm, joint bottom offers two U-type groove; Save middle and upper part under described compressor arm and stop pin is installed; Described stop pin and U-type groove clamping.
As preferred embodiment, described stop pin is straight pin.
Further, under described compressor arm, joint is convex shape.
The present invention compared with prior art, proposes a kind of middle foot pressing mechanism of sewing machine of anti-chiseling down, and in when eedle leaves sewing, presser feet continues to keep certain pressure to sewing under the action of the spring; Compressor arm saves under being divided on compressor arm joint and compressor arm, and the elasticity that phase mutual is certain, makes middle presser feet can not take away sewing when touching sewing; Its structure is simple, and anti-chiseling down successful, cost is lower, and use value is higher.

Detailed description of the invention
The middle foot pressing mechanism of sewing machine of anti-chiseling down as depicted in figs. 1 and 2, comprises head of sewing machine 1, is provided with mounting groove 2 inside described head of sewing machine, is provided with compressor arm lifting sub 3 in described mounting groove 2; Described compressor arm lifting sub 3 is installed by the first screw 4 and compressor arm save 5 upper ends; Run through inside described compressor arm saves 5 under having compressor arm and save 6; Save under described compressor arm saving 5 inner surfaces and compressor arm between 6 outer surfaces and spring 7 is installed; Under described compressor arm, joint 6 saves top outer and is provided with rotating-proof nut 8 on compressor arm; Save 6 lower ends under described compressor arm, by the second screw 9, middle presser feet 10 is installed; Save 6 peripheries, installation position under described compressor arm saving 5 and compressor arm and one depression bar cover 11 is installed.
Two U-type groove 12 are offered bottom described compressor arm saves 5; Save 6 middle and upper parts under described compressor arm and stop pin 13 is installed; Described stop pin 13 and U-type groove 12 clamping; Described stop pin 13 is straight pin.
Saving 6 under described compressor arm is convex shape.
The course of work: when presser feet in needs 10 is adjacent to sewing, compressor arm lifting sub 3 drives joint 5 on compressor arm to move downward; When central presser feet touches sewing, sewing has reaction force upwards to joint 6 under compressor arm, and under making compressor arm, joint 6 upwardly; As shown in Figure 3 and Figure 4, simultaneously because the effect of spring 7 makes middle presser feet 10 touch sewing all the time; When central presser feet 10 needs to leave sewing, compressor arm lifting sub 3 drives joint 5 on compressor arm to move upward; As shown in Figure 5 and Figure 6, under the tension force effect of spring 7, save 6 under compressor arm and move downward a bit of distance, and stop motion under the restriction of rotating-proof nut 8, now stop pin 13 can not depart from the U-lag 12 that compressor arm saves; By regulating rotating-proof nut 8, saving the amount of moving up and down of 6 under adjustable compressor arm, also have adjusted the Tensity size of spring 7 simultaneously.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
