Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, specifically to a connector for a motor and controller of a household sewing machine. Background Technology

[0002] Household sewing machines combine functions such as straight sewing, zigzag sewing, and buttonhole sewing. They are generally driven by human power, but some are driven by electric motors. Household sewing machines driven by electric motors need to be equipped with a household sewing machine motor for use.

[0003] However, the position of existing household sewing machine motors is not adjustable after fixed installation, which makes them unsuitable for different installation needs and has low practicality. Furthermore, the socket body in the controller connector of existing household sewing machine motors has defects such as high cost, low processing efficiency, high processing difficulty and low reliability.

[0004] To address the aforementioned problems, the inventors proposed a connector for a household sewing machine motor and controller. Utility Model Content

[0005] To address the issues of the non-adjustable position of existing household sewing machine motors after fixed installation, and the high cost, low processing efficiency, high processing difficulty, and low reliability of the socket body in the controller connector of existing household sewing machine motors, the purpose of this utility model is to provide a household sewing machine motor and controller connector.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a household sewing machine motor, including a motor body, a support mechanism for use fixedly connected to the bottom end of the motor body, the support mechanism including a base frame, symmetrically arranged fixing holes through both sides of the bottom end of the base frame, a lead screw 1 rotatably inserted into the middle of the base frame, a handwheel 1 fixedly installed at the top end of the lead screw 1, and an array of grooves 1 opened on the outer wall of the handwheel 1, a slide is threaded onto the lead screw 1, and the slide is slidably locked in the base frame, a second lead screw 2 rotatably inserted into the slide, and a I-shaped frame threaded onto the second lead screw 2, a second handwheel 2 fixedly installed at one end of the second lead screw 2, and an array of grooves 2 opened on the outer wall of the second handwheel 2, the I-shaped frame and the slide are slidably connected, and the top end of the I-shaped frame is fixedly connected to the motor body.

[0007] Preferably, a symmetrically distributed guide rod is fixedly installed on the inner side of the base frame, and the slide is slidably sleeved on the guide rod. A symmetrically arranged guide hole is opened through the bottom end of the slide, and the guide rod is slidably inserted into the guide hole.

[0008] Preferably, a guide rod two is fixedly installed on the upper inner side of the carriage, and the I-frame is slidably sleeved on the guide rod two. A guide hole two is opened through the I-frame, and the guide rod two is slidably inserted into the guide hole two.

[0009] The controller for the motor of a household sewing machine is connected to the machine, including a socket module and an external docking assembly module. The external docking assembly module can be slidably inserted into the socket module.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. Through the use of the bracket mechanism, after the motor body is fixedly installed, handwheel one or handwheel two can be rotated as needed, thereby driving screw one or screw two to rotate, which in turn can drive the slide to move in the vertical direction or drive the I-frame to move in the horizontal direction. Furthermore, the installation height and horizontal installation position of the motor body can be adjusted as needed, thereby adapting to different installation requirements and effectively improving the practicality of the motor body.

[0012] 2. The copper pin conductor on the socket module has been changed from a machined copper pin structure to a stamped copper pin structure, thereby reducing costs and improving processing efficiency. Furthermore, the connection between the socket copper pin and the socket module has been changed from injection molding to a snap-fit ​​assembly method, which further reduces processing difficulty. In addition, the connection structure between the socket copper pin and the motor lead has been changed from a threaded nut connection to a copper pin terminal crimping, thereby improving efficiency and increasing reliability. Moreover, the socket module and the external docking assembly module have been improved to a modular assembly method, which allows for modification of only the external structural components when matching different sewing machine models.
