Sewing machine protection cover capable of preventing fingers from being pricked

Abstract

The invention provides a sewing machine protection cover capable of preventing fingers from being pricked. The protection cover comprises a protection ring and connecting rod fixing pieces, wherein the protection ring is mounted on the connecting rod fixing pieces through a left connecting rod piece and a right connecting rod piece, and the connecting rod fixing pieces and machine head fixing pieces form a whole and can be mounted on the lower side of a sewing machine head. When protection is required, the protection ring can be turned to the lower part, and the periphery of a sewing machine is covered; when the protection ring is required to be moved away, the protection ring is upwards rotated by 90 degrees around connecting rod rotating shafts in the connecting rod fixing pieces. With the adoption of the sewing machine protection cover, the defect that the fingers are pricked due to slow reaction of a photoelectric protection device and circuit failure can be overcome, and the danger that the fingers of the sewing beginner are pricked can be effectively prevented. Besides, the protection cover is made of high-strength transparent plastic and cannot shield the sight of an operator, and industrial accidents of a sewing operator can be effectively prevented.

Description

technical field [0001] The invention relates to the field of textile sewing, in particular to a sewing machine protective cover for preventing finger pricking. Background technique [0002] The sewing machine is a very convenient suturing tool that is widely used, but it requires certain skills to operate the sewing machine. Novices often cannot do good coordination with their hands and feet, which can easily cause broken needles, broken threads, and possibly damage the fabric. The serious thing is to prick or pierce the finger. Once such an accident occurs, it must be sent to the hospital for treatment. Although this is a relatively small safety accident and will not endanger life, it will bring some pain to the person involved. Therefore, a kind of protective device of sewing machine should be arranged to ensure the safety of operators, especially to protect the safety of novice sewing personnel. In this regard, I have seen some reports about safety protection devices. Mo...

Problems solved by technology

In this regard, I have seen some reports about safety protection devices. Most of them use the principle of photoelectric induction and infrared induction. Many of them are only theoretical assumptions, and no real practical products have been seen. The key reason is the protection action of photoelectric induction. The response time of the machine cannot meet the requirements, and the motor that drives the sewing needle has a large inertia, and there is no time to brake, so it will still cause finger pricking accidents.
