Description

Technical Field

[0001] The utility model relates to the technical field of sewing thread placement racks, in particular to a sewing thread placement rack. Background Art

[0002] Sewing thread is the thread needed for knitted clothing products. It can be divided into three categories according to its raw materials: natural fiber sewing thread, synthetic fiber sewing thread and mixed sewing thread. Sewing thread is generally wound on a sewing thread bobbin for use. A sewing thread placement rack can prevent the sewing thread bobbin from moving due to traction during use.

[0003] According to a search, Chinese patent document, publication number: CN221588887U, discloses a sewing thread placement rack. By providing a first placement rod, a second placement rod, a mounting slot, a compression spring, and a limiting column, the height of the placement assembly can be adjusted according to the size of the sewing thread spool to be used, thereby making the device suitable for the installation and use of sewing thread spools of different sizes, increasing the scope of application of the device, thereby solving the problem that when the sewing thread is quickly pulled out of the sewing thread spool, an upward pulling force is applied to the sewing thread spool, making it easy to pull the sewing thread spool up. However, due to the fixed size of the support plate, larger sewing thread spools are easily detached from the support plate during the pulling process, affecting the normal operation of the sewing machine. However, the limiting plate of the sewing thread placement rack is connected by a cross-shaped clamping block and does not have a fixed structure. When in use, the sewing thread spool may drive the limiting plate to move together, resulting in poor stability. Utility Model Content

[0031] Specifically, there are two fixed plates 3 and two guide rods 4, the fixed plates 3 are perpendicular to the guide rods 4, and there are four movable seats 5. The advantage is that the guide rods 4 play a guiding role for the movable seats 5.

[0032] Specifically, two springs 6 are symmetrically arranged on the outer side of the fixed plate 3, and one end of the spring 6 away from the fixed plate 3 is fixedly connected to the movable seat 5. The advantage is that the spring 6 applies elastic force to both sides of the movable seat 5.

[0033] Example 2:

[0034] like Figure 1-4 As shown, as an improvement to the previous embodiment, multiple positioning holes 10 are provided equidistantly above and below, and positioning screw 10 extends through the sliding sleeve 8 into the interior of the positioning holes 10. The advantage is that the sliding sleeve 8 slides up and down along the outer side of the positioning plate 2. After sliding to the appropriate position, the positioning screw 10 is rotated into the nearest positioning hole 10 to position the sliding sleeve 8.

[0035] Specifically, the inner sleeve 7 passes through the support plate 11, and the protrusion 12 is a conical structure. The advantage is that the sewing thread barrel is sleeved on the outside of the inner sleeve 7, and the protrusion 12 is engaged with the outside of the upper end opening of the sewing thread barrel, which plays a limiting role for the sewing thread barrel sleeve.
