The pedal brake is composed of a brake base 6, a brake tongue 5, a tension spring 3, a draw wire 7 which are connected. The pedal brake is arranged at the right side of a machine body and is fixed by the original holes, screws, etc., of the sewing machine. The utility model has the advantages of simple structure, confidential placement, sensitive brake and convenient operation, etc.

Description

Motor-driven domestic sewing machine pedal brake

A kind of machine control unit, the brake apparatus of using on the specifically electronic domestic sewing machine can make operating Sewing machines shut down at once according to operator's needs.

Old-fashioned treadle type sewing machine, the operator drives bull wheel by stepping on pedal, and then drives the wheel shaft rotation that flywheel is arranged, the pin bob that drives on the head reaches the sewing purpose, during work, desire allows machine shut down, and operator's only with hand catches the flywheel that is rotating to get final product.Present widely used domestic sewing machine is at small machine of the other increase of fuselage, directly drives the wheel shaft that flywheel is housed and rotates.The speed of machine run speed can be finished by the big or small drive speed adjustor of exerting oneself of foot pedal.This electric sewer save trouble and labor accelerated sewing velocity, but shortcoming is: the machine that is running up is stopped, with hand braking very dangerous, let alone slowly to slow down and too time-consuming.When people use Sewing machines, start every now and then always and stop, this shortcoming that is difficult to stop immediately of electric sewer has influenced operating efficiency.

The purpose of this utility model is a kind of brake gear simply and easily of design, and the operator can indiscriminately ad. as one wishes control the Sewing machines running or stop.

For achieving the above object, the utility model is achieved in that

A brake apparatus simple in structure--service brake is installed between the fuselage of electronic domestic sewing machine and flywheel, this service brake mainly is by the tongue of stopping, the seat of stopping, extension spring and backguy are formed, the seat of stopping is fixed on the fuselage, "T"-shaped elbow can be done in its top, a circular hole is arranged at the bottom, by in the slotted eye that has that "T"-shaped elbow insertion machine is die and screw by circular hole will stop the seat be fixed on fuselage with motor, stop tongue and stopping between seat to flexibly connecting, the tongue of stopping has two faces at an angle to each other--facade and plane, side links to each other with the "T"-shaped elbow of extension spring with the fuselage or the seat of stopping within the facade, facade can be pulled to fuselage, side is being fixed the skin of stopping outside the facade.The two ends up and down of backguy join with the plane and the pedal of the tongue of stopping respectively.Operator's desire will allow the Sewing machines of running stop, as long as foot pedal, backguy just affects the tongue of stopping to rotate, so the skin of stopping on the tongue of stopping just rides on the medial surface of flywheel, leans on frictional force therebetween to stop flywheel to rotate, and Sewing machines just quits work.If will allow Sewing machines resume work, the pin that only needs will step down on the pedal lifts, and the skin of stopping just breaks away from flywheel, and actuating motor gets final product thereupon.The utlity model has simple in structurely, latent keeping away is installed, easy to operate, advantages such as brake sensitivity.

Accompanying drawing has shown an embodiment of the present utility model:

Figure one is the electronic domestic sewing machine structural representation that service brake is housed.Left side figure is the front elevational view of complete machine, and right figure is the side view of fuselage, service brake;

Figure two is stop tongue and the combination schematic perspective view between the seat stopped.

Service brake is installed in the fuselage right side, between fuselage and flywheel 2.Stop tongue 5 and stopping between the seat 6 to flexibly connecting, so the top of the seat of stopping is a "T"-shaped elbow, is inserted into fuselage 2 during installation in the slotted eye that has 1; Stop the seat the bottom one circular hole 11 is arranged, screw pass this circular hole will stop the seat and motor 12 be fixed on the fuselage together.The stop facade and the plane of tongue is mutually the right angle, and the rubber skin 10 of stopping is equipped with in the outside of facade, inboardly is connected with a "T"-shaped elbow of stopping by extension spring 3.Stop and be connected with backguy 7 between the inner edge of plane and pedal 8 of tongue.Lay speed regulator 9 under the outer rim of pedal.During operation, when stepping under the foot pedal, tiptoe, the pedal starter motor; Sewing machines just turns round under the driving of motor, when needs are shut down, lifts tiptoe and steps under the heel, so the circuit automatic disconnection of motor; simultaneously pedal affect backguy, the tongue of stopping, the rubber skin of stopping compresses flywheel, machine is just out of service.

Claims (3)

1, a kind of electronic domestic sewing machine service brake is characterized in that: this service brake mainly is made up of the tongue of stopping (5), stop seat (6), the spring of stopping (3), backguy (7) etc., and the tongue and stopping stopped is movably connected between seat, and the facade and the plane of the tongue of stopping are at an angle to each other; One end of extension spring is connected with facade, and the other end is connected with fuselage, and the skin of stopping (12) is being fixed in the outside of facade, and the upper and lower side of backguy joins with plane of scraping tongue and pedal (8) respectively.

2, according to the service brake of claim 1, it is characterized in that: said upper end of stopping seat (6) is a T-shape elbow (13), and a circular hole (11) is arranged at the bottom of the seat of stopping.

3, according to claim 1,2 said service brakes is characterized in that the said extension spring other end is connected with fuselage, also can be connected with the T-shape elbow of the seat of stopping.
