Technical Field

[0001] This utility model relates to the technical field of thread frames, specifically a sewing machine thread frame. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on a fabric, allowing one or more layers of fabric to interweave or sew together. It can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products such as leather, plastic, and paper. The sewing thread is an important factor in connecting these products. In order to facilitate the use of sewing thread on the sewing machine, a sewing machine thread holder is set in a specific position on the sewing machine.

[0003] The existing sewing machine thread holders have a relatively fixed structure, making it difficult to adjust the position of the thread support tray and pallet, thus failing to meet different usage needs and reducing the effectiveness of the device. In addition, the angle of the thread holder cannot be flexibly adjusted according to actual needs, reducing the working efficiency of the sewing machine.

[0004] Therefore, we propose a sewing machine thread holder to address the problems mentioned above. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-4 A sewing machine thread holder includes a fixed plate 1 and a thread rod 2 movably installed at the top center of the fixed plate 1. A thread guide 3 is provided on the right side of the thread rod 2 near the top, and a placement frame 4 is provided below the bottom of the thread guide 3. Several trays 5 are fixedly installed at equal intervals on the top of the placement frame 4. A cavity is opened on the thread rod 2 near the top, and an adjustment component 6 is installed in the inner cavity of the cavity. The height of the thread guide 3 and the placement frame 4 can be adjusted by setting the adjustment component 6.

[0024] A mounting bolt 11 is fixedly installed at the middle of the bottom of the fixed plate 1, and several positioning grooves 12 are opened on the top of the fixed plate 1. The positioning grooves 12 are arranged in a circular array with the center of the line rod 2 as the axis, which is conducive to the snap-fit ​​positioning of the line rod 2.

[0025] A disc 21 is fixedly sleeved on the outer side of the pole 2 near the bottom end, and a positioning bolt 22 is threaded through the disc 21 near the right side. The output end of the positioning bolt 22 is inserted into the inner cavity of one of the positioning slots 12.

[0026] The lead frame 3 has several lead holes 31 at equal intervals, which facilitates the deployment of the conductor.

[0027] In this embodiment: During use, the mounting bolt 11 can be used to fix the installation of the plate 1 and the thread rod 2. After installation, the tray 5 and the thread guide hole 31 facilitate the placement and thread guiding of the sewing thread. During use, the angle of the thread rod 2 can be adjusted by rotating it according to actual needs. By rotating the positioning bolt 22, it can be moved upward, thereby moving away from the inner cavity of one of the positioning grooves 12. At this time, the angle of the thread rod 2 can be adjusted by rotating it. After adjustment, the positioning bolt 22 can be rotated in the opposite direction to make it continue to be inserted into the inner cavity of one of the positioning grooves 12, so as to achieve the snap-fit ​​positioning of the thread rod 2 after the angle adjustment.

[0028] Example 2

[0029] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-4The adjustment component 6 includes a threaded rod 61 movably installed in the middle of the cavity. Two threaded sleeves 62 are threadedly installed on the outer side of the threaded rod 61 near the top, and the threaded sleeves 62 are arranged vertically. A fixing rod is fixedly installed in the middle of the right side of the threaded sleeve 62. A rectangular opening is opened on the right side of the cavity. The right end of the fixing rod passes through the inner cavity of the rectangular opening and is fixedly connected to the lead frame 3 and the placement frame 4 respectively. The height of the lead frame 3 and the placement frame 4 can be adjusted, which is highly flexible.

[0030] A worm gear 63 is fixedly sleeved on the outer side of the threaded rod 61 near the bottom. A worm 64 is engaged on the front side of the worm gear 63, and the left end of the worm 64 extends through to the outer side of the rod 2 and is fixedly installed with a hand crank 65, which facilitates the rotation of the threaded rod 61.

[0031] Guide plates 621 are fixedly installed at the middle of the front and rear sides of the threaded sleeve 62, and guide rods 622 are slidably installed through the guide plates 621. The upper ends of the guide rods 622 are fixedly installed on the top wall of the cavity, which serves to guide and limit the threaded sleeve 62.

[0032] In this embodiment: the height of the lead frame 3 and the placement frame 4 can also be flexibly adjusted. By turning the hand crank 65, the worm gear 64 can be driven to rotate. When the worm gear 64 rotates, it will drive the threaded rod 61 to rotate through the worm wheel 63. When the threaded rod 61 rotates, it will drive the two threaded sleeves 62 to move up and down synchronously. When the threaded sleeves 62 move, they will drive the lead frame 3 and the placement frame 4 to move up and down synchronously through the adjacent fixed rod. After adjusting to a suitable height, the hand crank 65 can be stopped.

[0033] Working principle: During use, the mounting bolt 11 is used to fix the plate 1 and the thread rod 2. After installation, the tray 5 and the thread guide hole 31 facilitate the placement and thread guiding of the sewing thread. During use, the angle of the thread rod 2 can be adjusted according to actual needs. By rotating the positioning bolt 22, it can be moved upward, thus moving away from the inner cavity of one of the positioning grooves 12. At this time, the angle of the thread rod 2 can be adjusted by rotating it. After adjustment, the positioning bolt 22 can be rotated in the opposite direction to make it continue to be inserted into the inner cavity of one of the positioning grooves 12, realizing the snap-fit ​​positioning of the thread rod 2 after angle adjustment. In addition, the height of the thread guide frame 3 and the placement frame 4 can be flexibly adjusted. By rotating the hand crank 65, the worm gear 64 can be rotated. When the worm gear 64 rotates, it will drive the thread rod 61 to rotate through the worm wheel 63. When the thread rod 61 rotates, it will drive the two thread sleeves 62 to move up and down synchronously. When the thread sleeves 62 move, they will drive the thread guide frame 3 and the placement frame 4 to move up and down synchronously through the adjacent fixed rod. After adjusting to a suitable height, the hand crank 65 can be stopped.
