[0029] The following further describes in detail the embodiments of the utility model with reference to the drawings and embodiments. The following embodiments are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0030] Embodiment 1: As shown in the attached Figure 1 to the attached Figure 9As shown: The present utility model provides a rotary adjustment mechanism suitable for a fabric hat, including a fixing member and an inserting piece 5. A connecting seam is provided on the side wall of the inserting piece 5, and it is connected to the brim through the connecting seam. The fixing member includes an inner gear disc 1, an outer gear disc 3, and a rivet 4; a reserved hole 101 is formed on the circumferential side of the inner gear disc 1, a positioning plate 501 is fixedly connected to the side wall of the inserting piece 5, the positioning plate 501 is engaged with the reserved hole 101, and a limiting member is provided between the inner gear disc 1 and the outer gear disc 3;

[0031] The limiting member includes an assembly groove 102 formed on the side wall of the inner gear disc 1, several inner teeth 103 arrayed on the inner wall of the assembly groove 102, several cantilevers 301 provided on the circumferential side of the outer gear disc 3, and round teeth 302 fixed at the ends of the cantilevers 301.

[0032] Several limiting ribs 106 are fixedly connected to the inner wall of the reserved hole 101, several guide grooves 502 are formed on the side wall of the positioning plate 501, and the limiting ribs 106 are engaged with the guide grooves 502; the function of the reserved hole 101 is to cooperate with the inserting piece 5 on the brim and retain the detachable function. The limiting ribs 106 can enhance the stability of this structure and also cooperate with two matching guide grooves 502 on the inserting piece 5 to achieve the meshing stability between the inserting piece 5 and the rotating device and keep them from loosening from each other.

[0033] It further includes a top cover 2. A through groove 107 penetrates through the inner wall of the reserved hole 101, the positioning plate 501 is inserted into the through groove 107, an inverted tooth 503 is fixedly connected to the side wall of the positioning plate 501, a clamping groove 108 is provided on the inner wall of the through groove 107, a clamping rib 202 is fixedly connected to the inner wall of the top cover 2, the clamping rib 202 is engaged with the clamping groove 108, and the position of the inverted tooth 503 is adapted to the clamping rib 202. First, insert the inserting piece 5 into the reserved hole 101. At this time, the position of the inverted tooth 503 is aligned with the clamping groove 108. Then cover the top cover 2. The clamping rib 202 is inserted along the clamping groove 108, and at the same time, the clamping rib 202 is stuck on the side wall of the inverted tooth 503 to realize the limitation of the inverted tooth 503. The inverted tooth 503 can ensure that the inserting piece 5 will not easily slip off when cooperating with the rotating device.

[0034] A positioning groove 105 is provided on the side wall of the reserved hole 101, and a guide post 104 is provided on the inner wall of the assembly groove 102. There is a central hole between the positioning groove 105 and the guide post 104. The rivet 4 is installed in the positioning groove 105 and the central hole. The guide post 104 is slightly longer than the thickness of the outer gear disc 3. The central hole can ensure the smooth penetration of the rivet 4, and the diameter of the central hole and the diameter of the rivet 4 match each other.

[0035] A boss 303 is fixed on the surface of the outer gear disc 3, and the boss 303 is engaged with the guide post 104. The guide post 104 and the outer gear disc 3 are concentric with each other and control the two disc surfaces not to contact each other, minimizing friction to the greatest extent.

[0036] The number of cantilevers 301 is more than two, and different numbers such as 5 - 10 can be used to achieve corresponding functions.

[0037] The internal gear disk 1 and the external gear disk 3 are firmly fixed by rivets 4. Through the meshing of the external gear disk 3 and the internal gear 103, it can be stopped and positioned firmly at any position without loosening. The internal gear 103 and the cantilever 301 are meshed, which can ensure that the relative positions of the internal gear disk 1 are stable and do not shake at any rotation angle.

[0038] The insert piece 5 is fixed by the top cover 2. First, insert the insert piece 5 into the reserved hole 101. At this time, the position of the reverse tooth 503 is aligned with the card slot 108. Then cover the top cover 2, and the card rib 202 is snapped into the card slot 108 along the card slot 108. At the same time, the card rib 202 is stuck on the side wall of the reverse tooth 503. Through the engagement of the reverse tooth 503 and the card rib 202, the position change of the insert piece 5 is avoided, so that the position of the insert piece 5 is kept relatively fixed and no angular displacement and linear displacement will occur.

[0039] As can be seen from the above, the present rotation adjustment mechanism also has a mirror structure with the same structure. The main body is matched with the mirror structure and installed on the side of the headband of an ordinary hat to achieve detachable connection with various hat brims and the function of 360 - degree arbitrary rotation.

[0040] During installation, first install the external gear disk 3 in the assembly groove 102. At this time, pass the rivet 4 through the sealing groove 109 into the positioning groove 105. At this time, the rivet 4 passes through the central hole of the internal gear disk 1, the guide post 104 and the external gear disk 3. The insert piece 5 is connected to the hat brim through the connection seam on the side wall. The positioning plate 501 on the insert piece 5 is engaged with the reserved hole 101 on the periphery of the internal gear disk 1 to achieve the preliminary connection between the hat brim and the rotation adjustment mechanism. At this time, the guide groove 502 and the limit rib 106 are in limit cooperation, and the reverse tooth 503 and the card rib 202 are engaged, so that the internal gear disk 1, the external gear disk 3 and the insert piece 5 are firmly fixed; the boss 303 on the surface of the external gear disk 3 is engaged with the guide post 104 to ensure that the external gear disk 3 and the internal gear disk 1 are concentric and reduce friction.

[0041] The internal gear disk 1 and the external gear disk 3 are connected and limited by a limiting component. The limiting component is composed of the assembly groove 102 on the side wall of the internal gear disk 1, several internal teeth 103 on the inner wall, the cantilevers 301 on the periphery of the external gear disk 3 and the circular teeth 302 at the ends of the cantilevers 301. The rotation adjustment and positioning are achieved through the meshing of the internal teeth 103 and the circular teeth 302.

[0042] When the hat brim rotates, it drives the whole insert piece 5 to move. At this time, the internal gear disk 1 rotates, and the internal teeth 103 rotate relative to the circular teeth 302. The circular teeth 302 effectively limit the displacement of the hat brim, ensuring that the hat brim has a stable and controllable adjustment function.

[0043] Embodiment 2: On the basis of Embodiment 1, a sealing groove 109 penetrates through the outer wall of the internal gear disk 1. A top cover 2 is assembled at the sealing groove 109. A positioning disk 201 is fixedly connected to the inner wall of the top cover 2, and the positioning disk 201 is engaged with the sealing groove 109.

[0044] As can be seen from the above, when the top cover 2 is covered, the top cover 2 and the internal gear disk 1 are positioned relative to each other through the positioning disk 201, covering the rivet 4 so that it is not exposed. The overall rotation of the rotating device can be realized, enhancing the practicability and aesthetics.
