Description

Technical Field

[0001] The utility model relates to the field of sewing machines, in particular to a needle protection structure for sewing textiles. Background Art

[0002] The working principle of a sewing machine is mainly to achieve sewing through the up and down movement of the sewing thread and the movement of the fabric. Specifically, a sewing machine usually consists of the following parts:

[0003] Needle: The needle of a sewing machine moves the thread through the fabric in an up and down motion.

[0004] Thread: The thread passes through the spool and eye of the needle on the sewing machine and moves through the fabric as the needle moves.

[0005] Fabric: The fabric is placed on the table or under the presser foot of the sewing machine and moves with the movement of the sewing machine.

[0006] Driving device: The driving device of a sewing machine is usually a foot pedal or a motor, which moves the needle and thread through mechanical transmission or electric drive.

[0007] Presser Foot: The presser foot is used to hold the fabric in place so that it remains stable during sewing.

[0008] When using a sewing machine, the operator steps on the foot pedal or starts the motor, and the drive device drives the needle up and down. As the needle passes through the fabric, the thread also passes through the fabric, forming a stitching line with interweaving needles and threads. At the same time, the fabric moves forward under the action of the presser foot, achieving continuous stitching.

[0009] When the needle is raised and lowered at high speed to sew textiles, there is no protective structure on the outside of the needle. When the fingers push the textiles to operate, the high-speed movement of the needle touches the fingers and causes punctures, posing a safety risk. Utility Model Content

[0010] The purpose of the utility model is to provide a needle protection structure for sewing textiles to solve the defects mentioned in the above background technology.

[0011] To achieve the above-mentioned purpose, a needle protection structure for textile sewing is provided, comprising a sewing machine body, the sewing machine body is mounted on a workbench, a presser foot and a connecting rod are mounted at the bottom of the sewing machine body, a fixing seat is mounted at the bottom of the connecting rod, and the bottom of the connecting rod is fixedly connected to the needle through the fixing seat; the needle protection structure body is mounted on the right side of the sewing machine body;

[0012] The needle protection structure body includes a mounting block, and a guide channel is opened on the right side of the interior of the mounting block. At the same time, the guide channel is adapted to the size of the guide seat, and the guide seat is inserted into the interior of the guide channel, and a protection rod is fixedly arranged at the bottom of the guide seat; limiting channels are opened on both sides of the front of the mounting block, and limiting rods are installed on both sides of the guide seat. At the same time, the limiting rods are adapted to the size of the limiting channels, and the limiting rods are inserted into the interior of the limiting channels.

[0013] Preferably, the mounting block is a rectangular structure made of plastic material, and a limiting hole is provided in the middle of the mounting block. Meanwhile, the size of the limiting hole is larger than the connecting rod, and the connecting rod is inserted into the limiting hole.

[0014] Preferably, the guide seat is a "T"-shaped structure made of plastic material, and a locking head is installed on the guide seat. At the same time, a storage hole and a working hole are respectively opened on the right side wall of the guide channel.

At the same time, one end of the spring is fixedly arranged on the inner wall of the guide hole, and the other end of the spring is fixed to the locking head. Both the locking head and the guide hole are elliptical in shape.

[0017] Preferably, six groups of protection rods are evenly installed at the bottom of the guide seat, and the distance between two adjacent groups of protection rods is consistent. At the same time, the six groups of protection rods are arranged directly in front of the needle.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. When the needle is moving up and down at high speed to sew the textile on the workbench, six sets of protection rods are set in front of the needle. The six sets of protection rods are combined to form an anti-prick assembly. The anti-prick assembly will prevent the finger from moving further toward the needle to prevent the finger from being pricked by the needle;

[0020] 2. The locking head is inserted into the storage hole. The protective rod is lifted up and the needle at the bottom of the fixing seat can be replaced. BRIEF DESCRIPTION OF THE DRAWINGS
