Embodiment Construction

[0020] The present invention will be further described below with specific embodiment, see figure 1 —4:

[0021] The feeding adjustment stud on the sewing machine includes an adjustment stud cylinder 10 and a head 20 connected in contact with the feed regulator. The axes of the cylinder body 10 are collinear.

[0022] The above-mentioned adjusting stud cylinder 10 is: one end of the cylinder is axially provided with a head mounting hole 101 collinear with the axis of the cylinder, and the other end is provided with a threaded hole 102 whose axis is collinear with the cylinder. Two constricted portions 103 are provided at intervals in the middle of the outer cylindrical surface of the cylinder, and external threads 104 are arranged on the outer cylindrical surface of the cylinder near the end where the head mounting hole 101 is provided. The external thread 104 is a trapezoidal thread or a rectangular thread.

[0023] The opening end of the head mounting hole 101 of the adju...

Abstract

The invention belongs to the technical field of sewing machine accessories and particularly relates to a novel feeding adjustment stud on a sewing machine. The novel feeding adjustment stud comprises an adjustment stud body and a head part, wherein the head part is in contact connection with a feeding adjuster and is fixedly arranged at one end of the adjustment stud body, and in addition, the head part and an axes of the stud body are collinear. The novel feeding adjustment stud consists of the adjustment stud body and the head part and is in a split structure, the adjustment stud body and the head part are made of different materials, the adjustment stud body is made of metal materials, the head part is made of non-metallic materials (such as plastics), during the needle distance adjustment, the head part is in contact connection with the feeding adjuster, the feeding adjuster is made of metal materials, the noise can be greatly reduced through the grinding-in of the metal materials and the non-metallic materials, the whole machine performance and the product quality of the sewing machine are improved, in addition, the production cost can be reduced, meanwhile, the adjustment stud body and the head part are in tight matching or threaded connection, the connection is convenient, the assembly is simple, and the novel feeding adjustment stud is suitable for being used on various kinds of sewing machines.

Description

Technical field: [0001] The invention belongs to the technical field of sewing machine accessories, in particular to a novel feeding adjusting stud on a sewing machine. Background technique: [0002] The feeding adjustment stud on the sewing machine is used to adjust the stitch distance. One end of the cylinder part of the feeding adjustment stud is screwed to the target plate, and the other end of the cylinder part is the head of the spherical body. When adjusting, the dial is rotated, and the spherical body on the feeding adjustment stud rotates to adjust its position on the casing and is connected with the feeding regulator so as to achieve the purpose of adjusting the stitch distance. Since the head and the cylinder are integrally formed, one material is used, which is metal material. Since the feeding regulator is also made of metal material, the noise is relatively large during the working process of the sewing machine, which affects the overall performance of the se...
