The beneficial effect of the utility model is; The circuit board of control circuit is loaded on loam cake inside; Thereby avoid the connecting rod that links to each other with pedal is installed, simplified the overall structure of Sewing machines, can the utility model be installed in the optional position through base plate is installed; Use also easily, avoided that the people is long-time to adopt work posture, a fatiguability even cause the tired excessively occupational disease that causes dampening of certain body part.
Description of drawings
Fig. 1 is the structure cross-sectional schematic of a kind of sewing machine foot pedal of the utility model;
Fig. 2 is the decomposing schematic representation of a kind of sewing machine foot pedal of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
Referring to Fig. 1, Fig. 2, a kind of sewing machine foot pedal structure comprises a pedal 100, and the downside of said pedal 100 is provided with a loam cake 200, and the bottom of said loam cake 200 is provided with one base plate 300 is installed; Said pedal 100 and loam cake 200 through one be fixed in pedal bearing pin 400 be connected, said bearing pin is provided with opening, is with a torsion spring 410 on the said bearing pin 400, an end of said torsion spring 410 and the rear end of loam cake are fixed, the other end is stuck in bearing pin 400 aperture positions; Said loam cake 200 inside also are fixed with a circuit board 420, correspondingly with circuit board on the said bearing pin are fixed with one through screw and nut and regulate parts 430; Said loam cake 200 rear ends are provided with a gear adjustment hole; Be provided with two coaxial springs 510 and spring 520 in the said gear adjustment hole; Be provided with a spacing guiding spacer 530 between two springs; Less spring 520 upper ends of diameter of said spacing guiding spacer top are provided with spring guiding push rod 540, are provided with a spacing guide nut 550 between said spring guiding push rod 540 and the loam cake 200.
Wherein, be provided with copper sheathing 210 in the hole of said loam cake 200 installation bearing pins 400, the front end of said loam cake 200 also is provided with a Sewing machines high-speed cruising positive stop lug boss 220; The afterbody of said loam cake 200 is provided with a Sewing machines presser foot lifter positive stop lug boss.The front end of said installation base plate 300 is provided with one " Z " shape flanging, and the angle of said " Z " shape flanging upper and lower side is the right angle, is provided with at least two pilot holes 311 in the upper end 310 of flanging.
The operation principle of the utility model is at first under the active force of torsion spring 410, and pedal 100 has front end around bearing pin 400 tip-tilted trend with respect to loam cake 200; Under the effect of spring 520, spring guiding push rod 540 has again the rear end of pedal 100 trend on top upwards, thus make pedal 100 under the effect of aforementioned two spring forces, be in a balance, moment is zero original state.When artificially the front end of pedal 100 being exerted pressure, pedal 100 is pivotally lowered into certain position around bearing pin 400 front ends, regulates parts 430 and rotates to the relevant position with bearing pin 400, touches the circuit of sewing at a slow speed on the circuit board 420, and Sewing machines carries out sewing work at a slow speed; If need Sewing machines to sew at a high speed; Then the front end to pedal 100 applies bigger pressure; The front end that makes pedal 100 is pivotally lowered into around bearing pin 400 and reaches maximum (top) speed when contacting with Sewing machines high-speed cruising positive stop lug boss 220; Regulate parts 430 along with bearing pin 400 rotates together, the circuit of sewing fast on the circuits for triggering plate 420.When sewing ends needs trimming, group line; Artificially exerted pressure in the rear end of pedal 100; Under the pressure of pedal 100, spring guiding push rod 540 moves downward, and spring 520 pressurizeds shorten; Fitted in the lower surface of spring guiding push rod 540 and the upper end of spacing guiding spacer 530; At this moment, regulate parts 430 with the drive of the fixing bearing pin 400 of pedal 100 under the position that is in trimming on the circuits for triggering plate 420, dials the circuit of line, the trimming of Sewing machines, thread-laying mechanism are accomplished trimming under the control of control circuit, group line moves; Continuation applies bigger pressure to the rear end of pedal 100; Spring guiding push rod 540 drives spacing guiding spacer 530 and under the situation that overcomes spring 510, spring 520 elastic force, moves down; Until pedal 100 is fitted with the Sewing machines presser foot lifter positive stop lug boss end face of loam cake 200 afterbodys; Regulate this moment parts 430 with the drive of the fixing bearing pin 400 of pedal 100 under be in the precalculated position of lifting the control circuit of presser feet on the circuits for triggering plate 420, Sewing machines is accomplished the presser foot lifter action.
The utility model is loaded on loam cake 200 inside with the circuit board 420 of control circuit; Thereby avoid installing the connecting rod that links to each other with pedal; Simplified the overall structure of Sewing machines; At least two pilot holes through the upper end that " Z " shape that base plate 300 front ends are provided with is installed is provided with can be installed in the optional position with the utility model, also can be put in ground separately and carry out sewing operation; Use also easily, avoided that the people is long-time to adopt work posture, a fatiguability even cause the tired excessively occupational disease that causes dampening of certain body part.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
