Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of overlock sewing machines, in particular to a novel needle selection box for overlock sewing machines. Background Art
[0002] Overlock machines, also known as hemming machines, edge-stitching machines, and sew-stitching machines, are generally available in three-, four-, or five-thread configurations. Their primary function is to prevent fuzzing on garment seams. Overlock machines are not only used for hemming, but can also be used to stitch T-shirts, sportswear, underwear, and knitwear. Overlock machines can cut and sew simultaneously, creating a mesh-like seam pattern, making them suitable for stretchy fabrics.
[0003] The needle selector box is an auxiliary component of an overlock sewing machine, used to store and select different needle models and types. It typically contains multiple needle holes, allowing for easy needle replacement and access according to sewing needs. However, traditional needle selector boxes lack a self-locking lid during use, making them prone to accidental opening. Alternatively, if the user forgets to close the lid, the opening may remain aligned with the needle channel, potentially causing the needle to fall out. The lid also lacks a self-locking function. Utility Model Content
[0004] The purpose of the utility model is to provide a novel needle selection box for an overlock sewing machine to solve the technical problems existing in the prior art.
[0005] In order to solve the above technical problems, the utility model provides a new needle selection box for an overlock sewing machine, comprising a base plate and a top groove opened on the top of the base plate, wherein the inner wall of the top groove is fixedly connected to a plurality of equidistantly distributed dividing strips, and a storage channel is formed between the dividing strips, and one end of the storage channel is a closed structure and the other end is an open structure. A rotary cover is movably provided on the top of the base plate, and an opening is opened on the side wall of the rotary cover, and an insert ring is fixedly connected to the side wall of the base plate, and a locking assembly is fixedly connected to the side wall of the base plate, and the locking assembly cooperates with the insert ring to lock the rotary cover.
[0006] Preferably, the locking assembly includes a positioning block fixed to the side wall of the rotary cover, and an insertion rod movably inserted on the positioning block. The upper end of the insertion rod is fixedly connected to a pull block, and a spring is fixedly connected between the pull block and the positioning block. The spring is sleeved on the insertion rod. When the rotary cover is locked, the lower end of the insertion rod is inserted into the inside of the insertion ring.
[0007] Preferably, an annular groove is provided on the outer circumferential side wall of the base plate, and a T-shaped limit block is fixedly connected to the inner wall of the rotary cover, and the T-shaped limit block is slidably arranged in the annular groove.
[0008] Preferably, a label is fixedly connected to the inner wall of the storage channel.
[0009] Preferably, a bottom storage groove is provided at the bottom of the base plate, and a bottom cover plate for sealing is provided at the bottom storage groove.
[0010] Preferably, a threaded groove is provided at the bottom of the base plate, a threaded positioning ring is fixedly connected to the top of the bottom cover plate, and the upper end of the threaded positioning ring is threadedly inserted into the threaded groove.
[0011] Preferably, the area of the opening is smaller than the area of the open structure of the storage channel.
[0012] Preferably, a rubber ring is fixedly connected to the bottom of the base plate.
[0013] Preferably, the bottom cover is disc-shaped, and the area of the bottom cover is larger than the area of the bottom storage tank.
[0014] Preferably, the top of the screw cap is made of a transparent material.
[0015] By adopting the above technical solution, the utility model has the following beneficial effects:
[0016] 1. In the present invention, after the needle is taken out and placed, the rotary cover is rotated so that the insertion rod moves to the insertion ring. At this time, the pull block is released, and the spring releases its elastic force, pulling the pull block and the insertion rod down, so that the lower end of the insertion rod moves to the inside of the insertion ring, thereby locking the rotary cover. At this time, the rotary cover has a protective mechanism to prevent the rotary cover from being opened by mistake and the needle inside from falling out. Secondly, it serves as a reminder to the user that the opening is not aligned with any storage channel at this time.
[0017] 2. In the present invention, a bottom storage slot is used to add additional storage space for storing spare threads, sewing clips and other small accessories, thereby improving the overall function; by inserting the threaded positioning ring on the bottom cover into the threaded groove, the bottom cover is installed and the bottom storage slot is also closed.
