Horizontal hook with replaceable hook thread section

Abstract

The invention discloses a horizontal rotating shuttle with a replaceable shuttle point line hooking part. The rotating shuttle comprises a main shuttle body, the auxiliary shuttle line hooking part, an inner shuttle body, a cover plate, a needle protecting plate, a circular bottom plate, a concave-convex clamping force relief groove and fastening screws. At least one groove is formed in the main shuttle body. At least one protruding blocks matched with the grooves is arranged on the auxiliary shuttle line hooking part. The first protruding blocks are inserted into the corresponding grooves, through holes with internal threads are formed in the centers of the grooves, blind holes with internal threads are formed in the first protruding blocks, and threads of the fastening screws are tightened and fixed into the blind holes after passing the through holes. The inner shuttle body is fixed to the main shuttle body with a rail through the cover plate, and the needle protecting plate and the circular bottom plate are fixed to the lower face and the left side face of the auxiliary shuttle line hooking part through screws. According to the horizontal rotating shuttle, the rotating shuttle body and the line hooking part are separately manufactured, a worn or ageing or shortened line hooking part of the rotating shuttle or the line hooking part which is broken due to machine failures can be conveniently replaced by a new auxiliary shuttle line hooking part, and therefore use and manufacturing cost is saved.

Description

technical field [0001] The invention relates to the field of sewing machine parts, in particular to a horizontal shuttle capable of replacing the thread-hook part of the hook tip. Background technique [0002] The rotary hook of the sewing machine is the core key component of the industrial sewing machine. After long-term continuous high-speed and high-intensity use, the hook line of the hook tip will be easily worn, aged, and damaged due to time, intensity and human error. Shortened, or broken due to machine failure, while the rest of the components are intact, which causes premature aging, cannot be used normally or at all, and loses normal functions. Usually, the expensive full-rotary hook body is replaced again. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned technologies, the present invention provides a horizontal hook with replaceable hook-hook portion. [0004] In order to achieve the above object, the present invention provide...
