[0002] A sewing machine thread spool holder is an essential sewing accessory, specially designed for large spools such as pagoda thread. It vertically secures the spools, preventing tangling and collapse. Available in various materials, including solid wood and metal, it boasts a sturdy structure and supports multiple spools simultaneously, improving thread handling efficiency and sewing smoothness. It's a practical tool for both home and industrial sewing.

[0003] A search revealed a sewing machine thread holder disclosed in announcement number CN214736579U, which includes a main rod. While the above device provides greater stability during use, it requires threading through a small hole, making operation inconvenient. Additionally, the thread exhibits poor stability during use and is prone to tangling. Therefore, a thread reel holder for sewing machines is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing technologies where thread needs to be passed through a small hole, which is inconvenient to operate, and the thread is unstable and prone to tangling during use. Therefore, this invention proposes a thread spool holder for sewing machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A thread spool holder for a sewing machine includes a base plate, on the surface of which a column is threadedly connected, and a horizontal plate is slidably fitted around the circumference of the column. At least one through hole is provided on one side of the horizontal plate for thread to pass through, and a through recess is provided at the top of the through hole for thread to be inserted.

[0007] At least one spring piece is fixed to the top of the horizontal plate by bolts and works with the through hole. The spring piece is bent and one end is located in the relief opening. The bent part of the spring piece can deform downward through the relief opening. In the normal state, one end of the bent part of the spring piece abuts against the side wall of the relief opening to form a closed space.

[0008] A wire clamping mechanism is provided on one side of the perforation for clamping the wire;

[0009] Two fixing mechanisms are installed at the bottom of the base plate to fix the base plate.

[0010] A limiting member is provided on the surface of the base plate for placing the wire coil.

[0011] As a further embodiment of this utility model, the fixing mechanism includes an L-shaped mounting bracket, which is fixed to the bottom of the base plate. A through fixing bolt is threaded to the bottom of the mounting bracket, and a top plate is rotatably connected to the top of the fixing bolt.

[0012] As a further improvement of this invention, a rubber pad is adhered to the top of the top plate.

[0013] As a further embodiment of this utility model, the limiting member includes a fixing post, which is threadedly connected to the top of the base plate, and a support plate is fixedly connected to the circumference of the fixing post for supporting the wire coil.

[0014] As a further embodiment of this utility model, the wire clamping mechanism includes a first fixed frame and a second fixed frame. Both the first fixed frame and the second fixed frame are fixed to the side of the horizontal plate near the through hole. A fixed clamping piece is fixedly connected to one side of the first fixed frame, and a movable clamping piece is slidably connected to one side of the second fixed frame. The middle parts of both the movable clamping piece and the fixed clamping piece are vertical, and the top and bottom are arc-shaped. A side frame is fixedly connected to one side of the second fixed frame, and a through adjusting bolt is threaded to one side of the side frame. One end of the adjusting bolt is rotatably connected to a pressure plate, which slides through the second fixed frame. A spring is installed between one end of the pressure plate and the movable clamping piece through a spring seat. A wire post is fixedly connected between the first fixed frame and the second fixed frame.

[0015] As a further embodiment of this utility model, one end of the horizontal plate is threaded with a through-hole set screw.

[0016] As a further embodiment of this utility model, a positioning groove is provided on one side of the column, and the set screw is located in the positioning groove.

[0017] As a further improvement of this utility model, a storage groove is provided on the surface of the base plate.

[0018] In this application, during use, the base plate and mounting bracket are fastened to one side of the sewing machine panel. Rotating the fixing bolt causes the top plate to contact the bottom of the sewing machine panel, thus fixing the base plate. The spool of thread to be placed is then placed on the fixing post, with one end of the spool pulled out. The thread is then pressed down from above the horizontal plate, causing the spring to press down and create a gap, allowing the thread to pass through the hole. The spring then returns to its original position, sealing the hole and preventing the thread from slipping out when slack. This also facilitates thread insertion into the hole, avoiding small holes and improving thread feeding efficiency. Simultaneously, the thread is pressed between the fixed clamp and the movable clamp. The spring force causes the movable clamp to hold the thread. During use, the thread slides between the first and second fixed frames, increasing stability and preventing loosening. Rotating the adjusting bolt adjusts the spring compression, thereby adjusting the clamping force on the thread, facilitating the use of threads of different thicknesses or roughnesses.

[0019] Beneficial effects: In this utility model, the thread spool holder for sewing machine thread holder has a relief opening above the hole, and a spring piece is fixed above the relief opening. This can seal the hole, prevent the thread from slipping when it is slack, and at the same time make it convenient for the user to put the thread into the hole, avoid threading through small holes, and improve thread feeding efficiency.

[0020] In this utility model, the thread spool holder for a sewing machine uses a combination of fixed clamping plates and movable clamping plates. The movable clamping plates clamp the thread using the elastic force of a spring. When the thread is in use, it slides between the first fixed frame and the second fixed frame, increasing the stability of the thread during use and preventing it from becoming loose.

[0021] In this invention, the perforation can be sealed to prevent the wire from slipping when it is slack. At the same time, it is convenient for the user to put the wire into the perforation, avoiding the need for small holes and improving the wire feeding efficiency. Meanwhile, the movable clamp holds the wire, and when the wire is in use, it slides between the first fixed frame and the second fixed frame, increasing the stability of the wire during use and preventing it from becoming loose.

In the normal state, one end of the bent part of the spring piece 13 abuts against the side wall of the relief opening to form a closed space. When laying the line, it is pressed down from above the horizontal plate 3. The line presses down one end of the spring piece 13 to create a gap, so that the line can reach the through hole 7. Then the spring piece 13 is reset, which can seal the through hole 7 and prevent the line from slipping when it is slack.

[0029] A wire clamping mechanism is provided on one side of the perforation 7 for clamping the wire;

[0030] Two fixing mechanisms are provided, both of which are located at the bottom of the base plate 1 to fix the base plate 1.

[0031] A limiting component is provided on the surface of the base plate 1 for placing the wire coil.

[0032] In this utility model, the fixing mechanism includes an L-shaped mounting bracket 8, which is fixed to the bottom of the base plate 1. The bottom of the mounting bracket 8 is threaded with a through fixing bolt 9, and the top of the fixing bolt 9 is rotatably connected to a top piece 10. The base plate 1 and the mounting bracket 8 are fastened to one side of the sewing machine panel. By rotating the fixing bolt 9, the fixing bolt 9 causes the top piece 10 to abut against the bottom of the sewing machine panel, thereby fixing the base plate 1.

[0033] The contact surface of the top piece 10 can be circular, square, or hexagonal, and the top rubber pad is 1-2mm thick to enhance anti-slip properties.

[0034] This application can be used in the field of sewing machines, or in other fields applicable to this application.

[0035] In another embodiment: Reference Figs. 1-3 A thread spool holder for sewing machines, which is applied in the field of sewing machines.

[0036] In particular, a rubber pad is bonded to the top of the top piece 10, which increases the stability of the fixation through the anti-slip effect of the rubber pad.

A through movable clamping piece 18 is slidably connected between the two through holes. The two ends of the movable clamping piece 18 are horizontally set, and the horizontal part slides in the through hole. The middle of the movable clamping piece 18 and the fixed clamping piece 17 are both vertical, and the top and bottom are arc-shaped. The middle of the movable clamping piece 18 and the fixed clamping piece 17 are opposite each other to clamp the wire. A side frame 21 is fixedly connected to one side of the second fixed frame 15. A through adjusting bolt 22 is threadedly connected to one side of the side frame 21. One end of the adjusting bolt 22 is rotatably connected to a pressure plate 19. The pressure plate 19 slides through the second fixed frame 15. A spring 20 is installed between one end of the pressure plate 19 and the movable clamping piece 18 via a spring seat. The spring force of the spring 20 pushes the movable clamping piece 18, causing it to move along the second fixed frame 15 and clamp the wire. Rotating the adjusting bolt 22 can adjust the position of the pressure plate 19, thereby changing the compression degree of the spring 20 and adjusting the clamping force on the wire to adapt to wires of different thicknesses, making it flexible to use. When the wire is in use, it slides between the first fixed frame 14 and the second fixed frame 15, increasing the stability of the wire during use and preventing it from becoming loose. Rotating the adjusting bolt 22 can adjust the compression degree of the spring 20, thereby adjusting the clamping force on the wire to facilitate the use of wires of different thicknesses or roughnesses. A guide post 16 is fixedly connected between the first fixed frame 14 and the second fixed frame 15, which limits the wire and prevents it from slipping between the first fixed frame 14 and the second fixed frame 15.
