Description

Technical Field

[0001] The utility model mainly relates to the technical field of manual embroidery frames, and specifically relates to a manual embroidery frame. Background Technique

[0002] Embroidery is the general term for various decorative patterns embroidered on fabrics with needles and threads. Embroidery is divided into two types: silk thread embroidery and feather embroidery. It is to pierce silk threads or other fibers and yarns with a needle in a certain pattern and color on the embroidery material to form a decorative fabric with embroidery traces; embroidery is an art of adding people's designs and productions to any existing fabric with a needle and thread. When performing embroidery, a manual embroidery frame is needed for assistance to facilitate the completion of embroidery.

[0003] After retrieval, a utility model patent with the publication number CN216947448U discloses a Miao portable manual embroidery frame, which includes a support frame. An adjustment mechanism is assembled on one side of the support frame. A square embroidery frame is rotatably connected to one side of the adjustment mechanism. The adjustment mechanism is used to drive the square embroidery frame to adjust its position. A rotation stop mechanism is assembled at the top of the adjustment mechanism. The rotation stop mechanism is used to provide rotation limitation for the square embroidery frame. The adjustment mechanism includes an extension frame, an output threaded rod, a driven bevel gear, a central shaft rod and a driving bevel gear; through the structural design of the adjustment mechanism, the height of the square embroidery frame can be conveniently adjusted, and then the needs of users with different heights can be met, thus greatly improving the overall applicability. And through the structural cooperation of the square embroidery frame and the rotation stop mechanism, while the angle of the square embroidery frame can be conveniently adjusted, the rotation stop limit after adjustment can also be completed, so as to facilitate the embroidery operation of the staff.

[0004] In the above patent technical solution, the height of the square embroidery frame can be conveniently adjusted through the adjustment mechanism. Through the structural cooperation of the square embroidery frame and the rotation stop mechanism, the angle of the square embroidery frame can be conveniently adjusted, and the rotation stop limit after adjustment can also be completed. However, when using the above patent technical solution, there are still the following deficiencies:

[0005] 1. In the above patent technical solution, the height of the square embroidery frame is adjusted through the adjustment mechanism. However, the overall adjustment mechanism in the above patent technical solution extends towards the user's bosom, resulting in that when the embroiderer operates, it is very easy to block the embroiderer from approaching the device, making it inconvenient for the embroiderer to embroider. Moreover, the design of this structure is complex and the manufacturing cost is high;

[0006] 2. In the above patent technical solution, through the structural cooperation of the square embroidery frame and the rotation stop mechanism, the angle of the square embroidery frame can be conveniently adjusted. However, when using the above patent technical solution, the specification of the set square embroidery frame is fixedly set. During the embroidery production process, there are many shapes, such as square or round, and there are also many different specifications. The fixedly specified square embroidery frame in the above patent technical solution will reduce the practicability of the manual embroidery frame.
