[0002] An embroidery hoop is an indispensable tool in embroidery, primarily used to hold fabric in place so that the embroiderer can perform delicate embroidery work. By using an embroidery hoop, the fabric can be stretched evenly, maintaining a flat and taut state, thus facilitating embroidery. An embroidery hoop typically consists of two ring-shaped or square frames with an adjustable knob or screw mechanism in the middle for securing the fabric. In terms of materials, embroidery hoops are available in various forms, including wood, bamboo, plastic, or metal, and come in different sizes and shapes to meet diverse embroidery needs.

[0003] However, existing embroidery hoops have certain limitations in practical use. They can usually only fix a local area of ​​the fabric, limiting the flexibility of the embroidery and the ability to adjust the embroidery area. Especially when dealing with long strips of fabric, the length of the fabric can affect the overall embroidery process, making the embroidery operation complicated and difficult to effectively store and organize.

[0004] Therefore, an adjustable embroidery hoop is provided to improve the efficiency and convenience of embroidery work. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The embodiments will be described in detail below to enable those skilled in the art to better understand the present invention:

[0029] An adjustable embroidery hoop, such as Figures 1 to 6 As shown, the basic structure includes an adjustable embroidery hoop with a first winding rod 1 and a second winding rod 2. The first winding rod 1 is rotatably mounted between two first support seats 3, and the second winding rod 2 is rotatably mounted between two second support seats 4. Two support connecting rods 5 are respectively provided between the first winding rod 1 and the second winding rod 2. A telescopic rod 6 is slidably mounted on each of the two support connecting rods 5. Specifically, each of the two telescopic rods 6 has a sliding groove in the support connecting rod 5, and slides along the groove. A two-way ratchet mechanism 7 is provided on each of the two support connecting rods 5, which is used to limit the movement of the telescopic rods 6, realizing self-locking adjustment of bidirectional movement.

[0030] The adjustment knob 8 has the following structure: Adjustment knobs 8 are rotatably connected to both bidirectional ratchet mechanisms 7. The adjustment knobs 8 are rotatably mounted on knob seats 9, and the bidirectional ratchet mechanisms 7 are housed inside the knob seats 9. This design allows for easy control of the bidirectional ratchet mechanisms 7 by rotating the adjustment knobs 8. It should be noted that since the bidirectional ratchet mechanism 7 is an existing technology, its structure and working principle will not be elaborated upon here. This utility model only utilizes the adjustment knobs 8 for external connection to the bidirectional ratchet mechanisms 7 to achieve the control effect.

[0031] Gear transmission structure: Each of the two telescopic rods 6 has a rack 10 on its side wall. A connecting gear 11 is rotatably mounted inside the knob seat 9, and one end of the connecting gear 11 meshes with the rack 10. When the bidirectional ratchet mechanism 7 drives the drive gear 12 to rotate, the drive gear 12 drives the connecting gear 11 to rotate, and the connecting gear 11 then meshes with the rack 10 on the telescopic rod 6, thereby realizing the sliding of the telescopic rod 6 on the supporting connecting rod 5.

[0032] The drive gear 12 and reversing mechanism: A drive gear 12 is rotatably mounted inside the knob seat 9. The other end of the connecting gear 11 meshes with the drive gear 12. A bidirectional ratchet mechanism 7 is connected to the drive gear 12. A reversing lever 13 is installed inside the bidirectional ratchet mechanism 7, and the reversing lever 13 is connected to the adjustment knob 8. By rotating the adjustment knob 8, the reversing lever 13 can be driven, changing the rotation direction of the bidirectional ratchet mechanism 7, thereby changing the rotation direction of the drive gear 12, and realizing the extension and retraction adjustment of the telescopic rod 6.

[0033] Elastic Structure: Two telescopic rods 6 are elastically installed inside the two supporting rods 5, and each supporting rod 5 contains a spring 14. The two telescopic rods 6 are connected to the springs 14. The springs 14 provide a certain degree of cushioning during the extension and retraction of the telescopic rods 6, preventing hard impacts, and also maintaining the fabric's tension to a certain extent.

[0034] The winding rod installation structure is as follows: The two ends of the first winding rod 1 are rotatably mounted between two first support seats 3 via bearings 15, and the two ends of the second winding rod 2 are rotatably mounted between two second support seats 4 via bearings 15. The use of bearings 15 reduces friction during the rotation of the winding rods, making their rotation smoother.

[0035] Braking Structure: A first brake knob 16 is located at one end of the first take-up rod 1. A first threaded bolt 17 is mounted on the first brake knob 16 and threaded onto the first support seat 3. A first friction rubber 18 is mounted on the first threaded bolt 17. A second brake knob 19 is located at one end of the second take-up rod 2. A second threaded bolt 20 is mounted on the second brake knob 19 and threaded onto the second support seat 4. A second friction rubber 21 is mounted on the second threaded bolt 20. When it is necessary to fix the position of the take-up rod, tighten the threaded bolt on the brake knob to make the friction rubber tightly contact the support seat, thereby preventing the take-up rod from rotating.

[0036] The winding groove structure includes a first winding groove 22 on the first winding rod 1 and a second winding groove 23 on the second winding rod 2. The winding grooves facilitate embedding the edges of the fabric, better securing the fabric and preventing it from slipping during winding.

[0037] Working principle: When using this adjustable embroidery hoop, first adjust the size of the hoop according to the size of the fabric and the embroidery requirements. Rotate the adjustment knob 8, which drives the reversing lever 13, controlling the rotation direction of the bidirectional ratchet mechanism 7. The bidirectional ratchet mechanism 7 drives the drive gear 12 to rotate, and the drive gear 12 meshes with the rack 10 on the telescopic rod 6 through the connecting gear 11, causing the telescopic rod 6 to slide on the support link 5, thereby changing the size of the embroidery hoop.

[0038] After adjusting the size of the embroidery hoop, insert the edge of the fabric into the first winding groove 22 of the first winding rod 1 and the second winding groove 23 of the second winding rod 2. Then rotate the winding rod to gradually wind up and tighten the fabric. If it is necessary to fix the position of the winding rod, tighten the first brake knob 16 and the second brake knob 19 so that the first friction rubber 18 and the second friction rubber 21 are in close contact with the first support base 3 and the second support base 4 respectively, preventing the winding rod from rotating.

[0039] If it is necessary to adjust the tension of the fabric during the embroidery process, the adjustment knob 8 can be finely adjusted again, and the elasticity of the spring 14 can be used to adjust the tension of the fabric to ensure that the embroidery work proceeds smoothly.

[0040] After the embroidery is finished, release the brake knob, take the fabric out of the winding slot, and then put the embroidery hoop away.

[0041] In summary, the adjustable embroidery hoop provided by this utility model effectively solves the limitations of existing embroidery hoops in use through the synergistic effect of multiple innovative structures, bringing more flexibility, convenience and higher efficiency to embroidery work.
