Embodiment Construction

[0016] The present invention will now be described in further detail with reference to the drawings and embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the constitutions related to the present invention.

[0017] For the convenience of description, the direction facing the operator when the guard plate device is installed on the sewing machine head is called front, the front of the operator is the back, the left hand side of the operator is left, and the right hand side is right. The guard plate is long in the left and right direction, high in the up and down direction, and wide in the front and back direction. However, the orientation cannot be used as a limitation to the structural position of the present invention.

[0018] Such as Figure 1-3 As shown, the needle guard device includes a flat box-shaped rectangular parallelepiped guard plate cover 2, ...

Abstract

The invention relates to a machine needle protection plate device for a sewing machine, which is characterized by comprising a flat box-shaped protection plate cover, wherein a long stripped opening is arranged on the wall surface at one side of the protection plate cover, a protection plate is accommodated in an internal space, and the protection plate can extend out of the protection plate cover from the opening. The machine needle protection plate device provided by the invention has the advantages that the protection plate is arranged in the protection plate cover, and safety and dustlessness are realized. When the machine needle protection plate device is used, the protection plate is pulled out to block a machine needle, convenience and practicability are realized, and parts are reduced. Elastic plastic pulleys are arranged at the side edge of the protection plate, so the protection plate extends out of the cover body and can be stopped at any height for adapting to various conditions. The lower end of the protection plate cover is provided with a notch, and the protection plate can be conveniently pinched for extending.

Description

Technical field [0001] The invention relates to a needle guard device of a sewing machine, in particular to a guard plate device with a protective cover. Background technique [0002] Usually, a cylindrical needle bar is installed in the sewing machine head. The lower end of the needle bar exposes the machine head shell and connects the organic needle. The needle is exposed in front of the operator. It moves up and down with high frequency during work. Once the needle breaks, it is extremely It is very dangerous to hurt the operator. Therefore, people think of setting a baffle in front of the needle, that is, between the needle and the operator, to block the broken needle that may fly out. Usually, the baffle is installed on the housing on the side of the lower end of the machine head facing the operator through some connectors, and the baffle can be rotated by the connector to protect against the needle when it is turned to the top of the needle or other The position and d...
