DETAILED DESCRIPTION

[0020] In order to make those skilled in the art better understand the present invention, the present invention is further explained in detail below with reference to the accompanying drawings and embodiments. It should be noted that the features in the embodiments and embodiments of the present application can be combined with each other without conflict.

[0021] The utility model provides an elastic band sewing positioning device in a typical embodiment, such as Figure 1 , 2 As shown, it includes an adjusting mechanism 1, a limiting mechanism 2 and a connecting block 5.

[0022] An adjustment mechanism 1 is provided at the upper end of the connecting block 5. Figure 3 As shown, the adjustment mechanism 1 includes an adjustment head 101, a slider 102, a screw 103 and a knob 104; the slider 102 is threadedly connected to the outside of the screw 103, one side of the screw 103 is rotatably set on one side of the adjustment head 101, the knob 104 is fixedly set on the other side of the screw 103, and the lower end of the slider 102 is fixedly set on the upper end of the connecting block 5.

[0023] When the horizontal position adjustment is required, the knob 104 is turned to drive the screw rod 103 to rotate inside the adjustment head 101, thereby driving the slider 102 to move outside the screw rod 102. When the slider 102 slides, it drives the connecting block 5 at its lower end to move horizontally.

[0024] The moving distance can be finely adjusted according to the scale line 4 at the front end of the adjustment head 101 to meet the positioning requirements of elastic bands of different widths.

[0025] Limiting mechanisms 2 are provided on both sides of the bottom of the connecting block 5. Figure 4 As shown, the limiting mechanism 2 includes two springs 201, two push blocks 202, two connecting rods 203 and two limiting blocks 204; an adjusting column 6 is slidably provided at the bottom of the connecting block 5, and an elastic band positioning mechanism is directly or indirectly provided at the lower end of the adjusting column 6.

[0026] The front end of the push block 202 extends to the outside of the connecting block 5, the top of the spring 201 is connected to the bottom of the push block 202, the middle part of the connecting rod 203 is rotatably connected to the fixed shaft, the two ends of the connecting rod 203 are respectively connected to the push block 202 and the limit block 204, and a plurality of limit grooves 14 adapted to the limit block 204 are opened on both sides of the adjusting column 6.

[0027] Applying appropriate pressure to the push block in the limiting mechanism 2 will cause the spring 201 connected to the push block 202 to contract. As the spring 201 contracts, the connecting rod 203 on one side of the push block 202 will rotate and transmit the rotation to the limiting block 204 on the side of the connecting rod 203, so that it can be smoothly disengaged from the limiting groove 14 of the adjusting column 14, so that the adjusting column 6 can slide freely at the lower end of the connecting block 5 and slide to the ideal position according to actual needs. When the adjusting column 6 reaches the required position, the pressure on the push block 202 is released, and the spring 201 will rebound and reset according to its inherent elasticity, and push the connecting rod 203 to rotate again, eventually causing the limiting block 204 to be embedded in the limiting groove 14 under the rebound action of the spring 201.

[0028] The elastic band is pressed tightly at the bottom of the elastic band positioning structure, which includes a pressing plate and a positioning plate. The rotating blocks 10 are arranged on both sides of the adjusting block 3. The lower ends of the rotating blocks 10 are fixed with pressing plates 11, and the bottom of the cylindrical structure is connected to the positioning plate 9. The elastic band is pressed tightly between the sewing machine table and the pressing plate 11 and the positioning plate 9, and the elastic band is fixed at a designated position below the sewing needle to prevent it from moving or offsetting during sewing.

[0029] In a preferred embodiment, the bottom of the adjusting column 6 forms a cylindrical structure, and a plurality of sliding holes 16 are opened on the outer surface of the cylindrical structure. The adjusting column 6 is externally sleeved with an adjusting block 3, and the front end of the adjusting block 3 is threadedly connected with a bolt 8 adapted to the sliding hole 16.

[0030] In order to facilitate the fixing of the elastic band, the operator turns the bolt 8 to disengage it from the adjusting block 3 and slide the adjusting block 3 outside the adjusting column 6. When the adjusting block 3 reaches the desired position, the bolt 8 at the front end of the adjusting block 3 is rotated to connect it to the sliding hole 16 outside the adjusting column 6, thereby adjusting the angle and position of the adjusting block 3, so that the pressure plate 11 presses the elastic band downward.

[0031] A slide groove 7 is provided at the upper end of the adjusting column 6, and the slide groove 7 on the adjusting column 6 cooperates with the lower end of the connecting block 5, thereby realizing horizontal positioning and ensuring the smooth operation of the elastic band during the sewing process.

[0032] The lower ends of the pressing plate 11 and the positioning plate 9 are both provided with anti-slip grooves 15, which can increase the friction force with the contact surface of the elastic band, thereby ensuring that the elastic band does not slide during sewing and enhancing the reliability of the elastic band fixation.

[0033] The rear end of the adjustment mechanism 1 is fixedly provided with a fixing block 12, and a fixing hole 13 is opened on the outside of the fixing block 12. Through the fixing block 12 and the fixing hole 13, the device can be stably mounted on the head of the sewing machine, and is not prone to displacement, thereby improving the stability and safety of the device and facilitating long-term use by users.

[0034] The scope of protection claimed by the present invention is not limited to the above specific implementation methods. For those skilled in the art, the present invention may have various deformations and changes. Any modification, improvement and equivalent substitution made within the concept and principle of the present invention should be included in the protection scope of the present invention.
