[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Embodiment 1, the utility model provides as follows Figure 1-Figure 10 A rotary embroidery frame shown includes a cross bar 1, a side bar 2 and a block 3. Two cross bars 1 and two side bars 2 are each provided. The two cross bars 1 are arranged parallel to each other, and the two side bars 2 are arranged parallel to each other. There are four blocks 3. The two cross bars 1 and the two side bars 2 are spliced ​​together to form a rectangular frame structure. The two ends of the embroidery cloth are respectively tied and fixed on the two cross bars 1. The embroidery cloth is embroidered in the rectangular frame structure. The four blocks 3 are respectively connected to the ends of the two cross bars 1 and the two side bars 2 spliced ​​together. It is a common embroidery frame structure and will not be described here.

[0034] In order to solve the problems that the embroidery cloth needs to be frequently disassembled and assembled and that the embroidery cloth is not easy to be tightened when used, the cross bar 1 is rotatably arranged relative to the block 3 in the present invention. When the cross bar 1 is rotated, since the end of the embroidery cloth is tied to the cross bar 1, the embroidery cloth will be wound and tightened, thereby achieving the purpose of tightening the embroidery cloth. In the utility model, based on the setting that the cross bar 1 rotates relative to the block 3, it is only necessary to subsequently rotate the cross bar 1 to adjust the tension of the embroidery cloth, and there is no need to tighten the embroidery cloth when fixing it, so the operation is convenient.

[0035] Furthermore, based on the rotatable arrangement of the crossbar 1 relative to the block 3, the appropriate area of ​​the embroidery cloth can be switched to the rectangular frame structure, without the need to frequently disassemble and assemble the embroidery cloth to achieve the purpose of changing the embroidery area.

[0036] The utility model discloses a method of rotatably setting the crossbar 1 relative to the block 3, but the tenon 9 is required to complete the positioning of the crossbar 1 relative to the block 3. Similar rotation structures are included in the protection scope. The utility model discloses specific settings of two rotation structures.

[0037] Embodiment 2 discloses the first setting mode of the rotating structure, referring to Figure 1 and 5 , Figures 9 and 10 As shown in, specifically: the inner cylinder 14 of the rotating structure is provided with an inner tenon hole 15, and the inner tenon hole 15 is provided with four, and the four inner tenon holes 15 are distributed at equal angles relative to the axis of the inner cylinder 14; a circular hole for the inner cylinder 14 to be movably inserted is provided in the block 3, and a first tenon hole 10 and a second tenon hole 11 are provided on the side of the block 3, and the second tenon hole 11 corresponds to the inner tenon hole 15. When the cross bar 1 and the block 3 are relatively fixed, the inner cylinder 14 needs to be inserted into the circular hole, and then the second tenon hole 11 and the inner tenon hole 15 are fixed by the tenon 9 to achieve relative fixation between the cross bar 1 and the block 3; when the cross bar 1 needs to be rotated, the tenon 9 needs to be pulled out first, and then the cross bar 1 is rotated, and the inner cylinder 14 can be rotated in the circular hole. When it is rotated to a suitable position, the tenon 9 is again inserted into the corresponding second tenon hole 11 and the inner tenon hole 15 to position the cross bar 1 and the block 3 again.

[0038] In the present invention, a rectangular sheet-shaped tenon plate is also provided at the end of the side rod 2 , and the tenon plate is inserted into the first tenon hole 10 to achieve relative fixation between the side rod 2 and the block 3 .

[0039] In order to prevent the inner cylinder 14 from escaping from the circular hole, a plug 13 is fixedly connected to the end of the inner cylinder 14. The plug 13 is movably restricted in the circular hole inside the block 3, preventing the inner cylinder 14 from escaping from the circular hole and achieving the purpose of limiting.

[0040] A scale 12 is provided at one end of the block 3 close to the inner cylinder 14, and there are four scales 12. The four scales 12 are respectively arranged in the middle of the four sides of the block 3. The scales 12 are used to indicate the rotation position of the cross bar 1. The cross bar 1 can be fixed after being rotated to the corresponding position. In this embodiment, scales 12 are also provided in the middle of the four sides of one side of the connecting bracket 5 close to the block 3, and the scales 12 also serve as an indicator.

[0041] Among them, the end of the inner cylinder 14 away from the block 3 is fixedly connected to the connecting support 5, the connecting support 5 is an L-shaped structure, and a connecting block 4 is fixedly provided at the end of the cross bar 1; the connecting block 4 and the connecting support 5 are fixedly connected; the connecting block 4 and the connecting support 5 can be fixed by a G-shaped clamp 6. Specifically, the G-shaped clamp 6 is installed on the connecting support 5, and a card slot 8 is provided on the connecting block 4. The G-shaped clamp 6 fixes the connecting block 4 on the connecting support 5. The G-shaped clamp 6 is also provided with an adjusting screw 7. The adjusting screw 7 can adjust the G-shaped clamp 6 to relatively press the connecting support 5 and the connecting block 4.

[0042] It should be noted that the card slot 8 can also be set on different surfaces of the connecting block 4 and adjusted according to actual needs to facilitate the use of the G-shaped clip 6.

[0043] As another embodiment, the connection block 4 and the connection bracket 5 can also be fixed by screws, T-shaped screws or any other means, such as Figures 9 to 10 As shown in , as long as the fixed purpose is achieved, it can be adjusted according to actual aesthetic needs and is not limited here.

[0044] In Example 3, a second configuration of the rotating structure is disclosed, referring to Figure 6 and 7 As shown in the figure, the end of the inner cylinder 14 away from the block 3 is fixedly connected to the cross bar 1. When the cross bar 1 is rotated, the inner cylinder 14 can rotate directly in the round hole. This embodiment provides several different rotation methods, mainly to adapt to the replacement of old products with new ones, and to select different rotation methods for modification according to existing products.

[0045] A side of the crossbar 1 close to the block 3 is also provided with scales 12. Here, there are four scales 12, which are distributed in a circular array. The function of the scales 12 is to indicate, which will not be elaborated here.

[0046] In Example 4, reference Figure 3 and 4As shown in the figure, one end of the tenon 9 is a round head and the other end is a rectangular plate structure. The end with the rectangular plate structure is inserted into the corresponding second tenon hole 11 to achieve relative fixation of the cross bar 1 and the block 3. The round end of the tenon 9 can also be selectively embedded with a magnet for user convenience. Generally, an embroidery needle or other tools can be used to suck out the tenon 9 and complete the quick disassembly of the tenon 9. Based on the magnet embedded in the tenon 9, the tenon 9 can also be completely pre-embedded in the block 3 to maintain the overall aesthetics and try to have no protrusions.
