Description

Technical Field

[0001] This utility model relates to the field of sewing machines, and in particular to an automatic reset device for the button pull rod of a sewing machine. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to create one or more stitches on fabric, so that one or more layers of fabric are interwoven or sewn together.

[0003] Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. The stitches produced are neat, beautiful, flat, and strong. Sewing is fast and easy to use. This has led to the development of art forms such as hand-pressed embroidery and computerized embroidery.

[0004] Currently, in existing sewing machines on the market, the button pull rod moves back and forth during operation. This continuous movement causes working errors, making it impossible for the button pull rod to maintain a perpendicular position to the sewing machine's working surface. This results in reduced working accuracy during sewing, lower product quality, and unsatisfactory practical application results. Utility Model Content

[0005] This invention aims to overcome the shortcomings of the prior art by providing an automatic reset device for the button pull rod of a sewing machine, which can keep the button pull rod perpendicular to the working surface of the sewing machine, thereby improving the sewing accuracy of the sewing machine and enhancing product quality.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: This automatic reset device for the button pull rod of a sewing machine includes a button pull rod seat, a button pull rod is provided on the button pull rod seat, a button pull rod bracket is provided on the side of the connection between the button pull rod and the button pull rod seat, the button pull rod bracket is set on the button pull rod seat, a reset torsion spring is provided between the button pull rod bracket and the button pull rod seat, a snap fastener is provided on the button pull rod seat, and the button pull rod bracket is installed on the button pull rod seat through the snap fastener.

[0007] Furthermore, a pull rod spring is provided on the button pull rod, and the pull rod spring is disposed between the button pull rod and the button pull rod seat.

[0008] Furthermore, a reset detection switch is provided on the button pull rod bracket, and the reset detection switch is located on one side of the button pull rod.

[0009] Furthermore, a working shaft is provided on the button pull rod bracket, the working shaft passes through the button pull rod seat, the reset torsion spring is installed on the working shaft and located inside the button pull rod seat, and the snap ring is installed on the working shaft and located outside the button pull rod seat.

[0010] The beneficial effects of this utility model are: the automatic reset device for the button pull rod of the sewing machine can keep the button pull rod and the working surface of the sewing machine perpendicular, which can improve the sewing accuracy of the sewing machine, improve product quality, have good performance, and facilitate promotion.

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] Referring to the attached diagram: This automatic reset device for the button pull rod of a sewing machine includes a button pull rod seat 1, which is used to install the remaining structures and provides support. A button pull rod 2 is mounted on the button pull rod seat 1. During sewing, the button pull rod 2 moves back and forth. A button pull rod bracket 3 is provided on the side of the connection between the button pull rod 2 and the button pull rod seat 1. The button pull rod bracket 3 mainly supports the automatic reset structure. The button pull rod bracket 3 is mounted on the button pull rod seat 1. A reset torsion spring 4 is provided between the button pull rod bracket 3 and the button pull rod seat 1. After the button pull rod 2 moves back and forth, the reset torsion spring 4 resets the button pull rod 2, keeping the button pull rod 2 perpendicular to the sewing machine working surface. This improves the sewing accuracy and product quality. A snap ring 5 is provided on the button pull rod seat 1. The button pull rod bracket 3 is mounted on the button pull rod seat 1 through the snap ring 5, which provides stable installation.

[0017] A pull rod spring 6 is provided on the button pull rod 2, and the pull rod spring 6 is located between the button pull rod 2 and the button pull rod seat 1. In this configuration, the pull rod spring 6 acts as a damper, achieving a shock absorption effect and further improving the sewing accuracy of the sewing machine.

[0018] A reset detection switch 7 is installed on the button pull rod bracket 3, and the reset detection switch 7 is located on one side of the button pull rod 2. In this configuration, the reset detection switch 7 has contacts to complete the corresponding work.

[0019] A working shaft 8 is provided on the button pull rod bracket 3. The working shaft 8 passes through the button pull rod seat 1. The reset torsion spring 4 is installed on the working shaft 8 and located inside the button pull rod seat 1. The snap ring 5 is installed on the working shaft 8 and located outside the button pull rod seat 1.

[0020] During operation, the button pull rod 2 moves back and forth to keep it perpendicular to the sewing machine working surface. After the button pull rod seat 1 and the reset torsion spring 4 are fitted onto the button pull rod bracket 3, they are secured with the snap ring 5. Pulling down the button pull rod 2, which is damped by the pull rod spring 3, causes the button pull rod seat 1 to drive the contacts of the reset detection switch 7 to complete the relevant actions. At the same time, the reset torsion spring 4 reacts to the button pull rod seat 1, ensuring that the button pull rod 2 remains perpendicular to the sewing machine working surface.

[0021] like Figure 3 As shown, Figure 3 This is a front view, and also a schematic diagram showing that the button lever 2 is perpendicular to the working surface 9.

[0022] The features of this utility model embodiment are: it can keep the button pull rod and the sewing machine working surface perpendicular, which can improve the sewing accuracy of the sewing machine, improve product quality, have good use effect, and facilitate promotion.

[0023] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
