Description

Technical Field

[0001] The utility model relates to the technical field of exercise equipment, in particular to a leg clamp. Background Art

[0002] Existing leg assist devices or leg clamps are typically used to increase resistance during exercise or for rehabilitation training to help increase muscle strength or improve blood circulation. These devices generally consist of a fixed portion and an adjustable clamping structure to accommodate different leg sizes. However, traditional leg clamps often have some design limitations, such as difficult adjustment, low comfort, and limited functionality.

[0003] Deficiencies of existing technology:

[0004] 1. Inconvenient adjustment: Existing leg clamps often do not have the ability to make fine adjustments, making it difficult to adapt to the leg lengths and different exercise needs of different users.

[0005] 2. Single function: Many existing leg clamps only have basic clamping functions and lack other additional functions, such as massage function, and cannot provide additional health benefits.

[0006] Therefore, the existing technology has deficiencies and needs further improvement. Utility Model Content

[0062] The principle of this utility model is as follows:

[0063] Clamping mechanism

[0064] Structural composition: The leg clamp mainly includes a first shell 1, a second shell 2, a first clamp arm 3, a second clamp arm 4 and a first rack 5. The first shell 1 and the second shell 2 are buckled together to form an outer shell, and the left and right sides of the outer shell are respectively provided with a first opening 22 and a second opening 23.

[0065] The clamping arms cooperate with the rack: the first clamping arm 3 and the second clamping arm 4 are located at the first opening 22 and the second opening 23, respectively, and are arranged in a figure-eight shape. A first rack 5 is disposed vertically between the first and second clamping arms 3 and 4, with serrations on both the left and right sides. A first gear 6 and a second gear 7 are disposed on the ends of the first and second clamping arms 3 and 4 facing the first rack 5, respectively. These gears mesh with the serrations of the first rack 5.

[0066] Clamping Action: When the lower ends of the first clamping arm 3 and the second clamping arm 4 move toward or away from each other, the first gear 6 and the second gear 7 drive the first rack 5 to move upward or downward, thereby varying the clamping force. This design allows users to adjust the position of the first clamping arm 3 and the second clamping arm 4 to accommodate different leg sizes.

[0067] Protection and fixation

[0068] Protective disc design: In order to protect the user's legs from direct pressure from the clamping arms, the ends of the first clamping arm 3 and the second clamping arm 4 are respectively provided with a first protective disc 8 and a second protective disc 9, both of which are round disc-shaped designs, which can better disperse pressure and improve comfort.

[0069] Fixing method: Fix the first clamping arm 3 and the second clamping arm 4 to the leg by means of Velcro or straps to ensure that the leg clamp will not loosen or fall off during exercise.

[0070] Massage function

[0071] Massager integration: Two first connecting rods 10 are provided on the back of the first rack 5, and a massager is mounted on the connecting rods. The massager includes a third housing 11, a fourth housing 12, a control mainboard 13, a battery 14 and a vibration component.

[0072] Vibration Assembly Operation: The vibration assembly consists of the fifth housing 15, the sixth housing 16, the vibration motor 17, and the eccentric weight 18. The eccentric weight 18 is mounted on the rotating shaft of the vibration motor 17. When the vibration motor 17 is turned on, the eccentric weight 18 rotates and generates vibrations, which are then transmitted to the third housing 11 and the fourth housing 12, achieving a massage effect.

[0073] Control and Charging: The massager's control board 13 is electrically connected to the battery 14 and the vibration assembly. The user can adjust the massage intensity and mode using control buttons 19 located on the side of the fourth housing 12. A charging port 20 is located at the lower end of the fourth housing 12, through which the battery 14 can be charged. A waterproof cover 21 is provided on the charging port 20 to ensure normal operation in humid environments.

[0074] In summary, the leg clamp achieves precise clamping adjustment through a unique gear and rack structure and integrates a massage function, providing a multifunctional device that can be used for both exercise training and muscle relaxation.

[0075] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the protection scope of the present invention.
