[0027] Example:

[0028] Reference Figures 1-8 The utility model embodiment provides a thigh guard with adjustable tightness by a knob, comprising a sheath 1 with an opening on the surface and a retractable belt 2 installed at the opening of the sheath 1, wherein the sheath 1 and the retractable belt 2 are both made of elastic material, which may be spandex or polyester, and further comprising two groups of wire tubes 3 fixedly mounted on the sheath 1, wherein adjustment wires 4 are passed through the two groups of wire tubes 3, and an adjustment portion is provided on the sheath 1, which is used to reel in and release the adjustment wires 4.

[0029] When in use, through the setting of the adjustment part, the adjustment line 4 can be easily rolled up onto the winding drum 52 inside the shell 5, so that the opening of the sheath 1 is contracted, thereby fitting the sheath 1 to the thigh of the athlete. By adjusting the length of the adjustment line 4, the tightness of the thigh guard can be adjusted, so that the thigh guard can be suitable for different athletes, thereby meeting the wearing needs of different athletes and improving the practicality of the thigh guard.

[0030] The adjustment part includes: a shell 5, which is fixedly installed on the sheath 1, wherein a vertical rod 51 is fixedly connected inside the shell 5, and a winding drum 52 and a knob disk 53 are movably sleeved on the vertical rod 51, and both ends of the adjustment line 4 are inserted into the shell 5 and fixedly installed on the winding drum 52; two bevel gears 54, which are respectively fixedly connected to the bottom of the knob disk 53 and the top of the winding drum 52, wherein when the bottom surface of the knob disk 53 contacts the top surface of the shell 5, the two bevel gears 54 mesh with each other, and a guide part for making the winding drum 52 rotate unidirectionally is provided on the knob disk 53, and a knob sleeve 55 is detachably installed on the knob disk 53, and a limiting member is provided on the top of the vertical rod 51.

[0031] A damper is provided between the knob plate 53 and the vertical rod 51 , so that the knob plate 53 has a certain friction resistance when moving on the vertical rod 51 .

[0032] During use, by rotating the knob sleeve 55, which drives the knob disk 53 to rotate together, while driving the helical gear 54 and the wire reel 52 to rotate, it is convenient to wind the adjustment wire 4 onto the wire reel 52 inside the housing 5, causing the two sides of the sheath 1 to move towards each other, thereby contracting the opening of the sheath 1. By adjusting the length of the adjustment wire 4, it is convenient to adjust the tightness of the thigh guard, enabling the thigh guard to be suitable for different athletes, thus meeting the wearing needs of different athletes and improving the practicality of the thigh guard.

[0033] The guiding part includes a helical tooth ring 6 and an elastic rack 62. A through groove 61 is formed through the knob disk 53. One side of the elastic rack 62 is fixedly connected in the through groove 61, and the helical tooth ring 6 is fixedly connected inside the housing 5. When the bottom surface of the knob disk 53 contacts the top surface of the housing 5, the elastic rack 62 meshes with the helical tooth ring 6.

[0034] Specifically, during use, when the knob disk 53 drives the wire reel 52 to rotate, it drives the elastic rack 62 to slide along the inclined surface of the teeth of the helical tooth ring 6 by the principle of the ratchet, enabling the wire reel 52 to only rotate in one direction, preventing the adjustment wire 4 wound thereon from loosening due to the reverse rotation of the wire reel 52, thereby ensuring the stability of the calf guard adjustment.

[0035] When the bottom surface of the knob disk 53 moves away from the top surface of the housing 5, the two helical gears 54 are separated from each other, and the elastic rack 62 is separated from the helical tooth ring 6, which can release the one-way limit on the wire reel 52, thus facilitating the athlete to release the adjustment wire 4 wound on the wire reel 52.

[0036] The limiting part includes a limiting block 7 installed at the top of the vertical rod 51. A threaded hole 71 is formed at the top end of the vertical rod 51. A screw rod 72 is fixedly connected to the bottom of the limiting block 7, and the screw rod 72 is threadedly connected in the threaded hole 71. A turntable 73 is fixedly connected to the top of the limiting block 7.

[0037] During use, through the combined use of the turntable 73, the screw rod 72, the threaded hole 71, and the limiting block 7, the knob disk 53 can be limited to prevent the knob disk 53 from detaching from the vertical rod 51 during use. And when maintenance is required, by rotating the turntable 73, driving the limiting block 7 and the screw rod 72 to rotate, under the action of the thread, the screw rod 72 is disengaged from the threaded hole 71 to release the limit on the wire reel 52 and the knob disk 53, which is convenient for disassembling and maintaining structures such as the wire reel 52, the knob disk 53, and the helical gear 54 to ensure the use effect of the adjustment components.

[0038] A plurality of card slots 8 are formed on the surface of the knob disk 53. A plurality of teeth 9 are fixedly connected to the inner wall of the knob sleeve 55. When the knob sleeve 55 is sleeved on the knob disk 53, the teeth 9 are engaged in the card slots 8. The number of the card slots 8 and the teeth 9 is preferably 4.

[0039] Through the settings of the card slot 8 and the card teeth 9, it is convenient to quickly disassemble and assemble the knob sleeve 55, further improving the convenience of maintenance.

[0040] A plurality of anti-slip ridges 10 are fixedly connected to the knob sleeve 55. The plurality of anti-slip ridges 10 are arranged in a ring on the surface of the knob sleeve 55. The number of anti-slip ridges 10 is preferably 28.

[0041] Through the setting of the anti-slip ridges 10, the friction on the surface of the knob sleeve 55 can be increased, so that it is convenient for the athlete to apply force to rotate the knob sleeve 55.

[0042] During the use of this thigh guard with adjustable knob tightness, first, the athlete can put the sheath 1 and the telescopic belt 2 on his own thigh. Then, by rotating the knob sleeve 55 and driving the knob disc 53 to rotate together, at the same time driving the helical gears 54 and the wire reel 52 to rotate, it is convenient to wind the adjusting wire 4 onto the wire reel 52 inside the housing 5. During the winding process of the adjusting wire 4, the two sides of the sheath 1 move towards each other, and the opening of the sheath 1 is contracted, so as to fit the sheath 1 on the athlete's thigh. By adjusting the length of the adjusting wire 4, it is convenient to adjust the tightness of the thigh guard, so that the thigh guard can be suitable for different athletes, thus meeting the wearing needs of different athletes, and further improving the practicality of the thigh guard;

[0043] On the other hand, when it is necessary to loosen the sheath 1, the knob sleeve 55 can be pulled, driving the knob disc 53 to slide along the surface of the vertical rod 51, making the knob disc 53 away from the surface of the housing 5. At the same time, driving the two helical gears 54 to move away from each other, and driving the elastic rack 62 away from the helical ring 6 to release the one-way limit on the wire reel 52. Then pull the sheath 1 to pull out the adjusting wire 4 from the housing 5, and the sheath 1 set on the athlete's leg can be loosened.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
