One embodiment of the leg press as shown in fig. 1 to 5 comprises: a support structure, a leg pressing bar 6 and an adjustment structure. As shown in fig. 1 to 3, the supporting structure includes first pillar 4 and second pillar 14 that set up relatively and locate the base 9 of first pillar 4 and second pillar 14 bottom, first pillar 4 and second pillar 14 are hollow frame structure, the inside parallel of hollow frame structure is equipped with two guide arms 2, the vertical setting of guide arm 2, slider 3 and two guide arm 2 sliding connection, base 9 is the cuboid structure, be connected perpendicularly with first pillar 4 and second pillar 14, the bottom surface four corners of base 9 is connected with stabilizer blade 8 through branch 10, the bottom surface of stabilizer blade 8 is equipped with anti-skidding line, place the device on subaerial through stabilizer blade 8, make the device more steady. As shown in fig. 1 to 5, a leg pressing rod 6 is disposed between the first support 4 and the second support 14, a rotating shaft 1 is connected to both ends of the leg pressing rod 6, and the rotating shaft 1 is connected to the sliding block 3 in a sliding manner in the horizontal direction.

As shown in fig. 2 and 4, the adjusting structure is disposed on the first pillar 4, and includes a first rack 16 vertically disposed on one side of the inner wall of the first pillar 4, a second rack 11 disposed on the other side of the inner wall of the first pillar 4 opposite to the first rack 16, and a first gear 17 engaged with the first rack 16 and the second rack 11, the first rack 16 and the second rack 11 are disposed close to the slider 3, the width of the second rack 11 is the same as that of the first gear 17, and the width of the first rack 16 is twice that of the second rack 11. As shown in fig. 3 and 5, a third rack 20 is vertically and communicatively provided on one side of the inner wall of the second pillar 14, the third rack 20 is engaged with the second gear 15, and the width of the third rack 20 is the same as the width of the first rack 16. The rotating shaft 1 penetrates through the sliding block 3 and then is fixedly connected with the first gear 17 and the second gear 15 respectively, the rotating shaft 1 on one side of the first support column 4 is connected with the rocker 12 after extending out of the first gear 17, the rocker 12 is of an L-shaped structure, the rod body connected with the rotating shaft 1 is kept away from by the L-shaped structure, the rod sleeve 13 is sleeved with the rod sleeve 13, and the rod sleeve 13 is an elastic rubber sleeve which is convenient for a user to grasp. The first gear 17 has a fixed state meshed with the first rack 16 and the second rack 11 simultaneously, and an adjusting state that the rotating shaft 1 slides in the horizontal direction in the sliding block 3 by pulling the rocker 12 to drive the first gear 17 to be disengaged from the second rack 11 and only meshed with the first rack 16. When the first gear 17 is in the adjusting state, the rocker 12 is rotated to drive the first gear 17 to rotate, the first gear 17 moves up and down along the first rack 16, at the moment, the second gear 15 synchronously rotates, the second gear 15 synchronously moves up and down along the third rack 20, and therefore the leg pressing rod 6 moves up and down along the vertical direction.

As shown in fig. 5, a disc 19 is fixedly connected to the inner side of the second gear 15, an elastic member 18 is disposed between the disc 19 and the slider 3, the elastic member 18 is a spring, when the first gear 17 is in an adjustment state, the second gear 15 is close to the slider 3, the spring compresses to store energy, after the adjustment is completed, the rocker 12 is released, under the action of the elastic force of the spring, the second gear 15 is pushed away from the slider 3, and meanwhile, the first gear 17 is driven to return to a fixed state.

As shown in fig. 4, an elastic sleeve 7 is arranged outside the leg pressing rod 6, and the elastic sleeve 7 is an elastic rubber sleeve.

As shown in fig. 4 and 5, the leg pressing rod 6 and the rotating shaft 1 are fixedly connected through the ring 5, when the first gear 17 is in a fixed state, the ring 5 on one side of the first support 4 is not connected with the slide block 3 on the side, the ring 5 on one side of the second support 14 is connected with the slide block 3 on the side, when the first gear 17 is in an adjusting state, the ring 5 on one side of the first support 4 is connected with the slide block 3 on the side, and the ring 5 on one side of the second support 14 is separated from the slide block 3 on the side, that is, the ring 5 plays a limiting role for the first gear 17, so that the first gear 17 is prevented from being separated from the first rack 16 or the second gear 15 is prevented from being separated from the third rack 20 due to an excessively long sliding distance of the rotating shaft 1.

When the leg pressing device of the embodiment is used for leg pressing training, the height of the leg pressing rod 6 is adjusted according to the height and flexibility of a user, firstly, the rocker 12 is pulled outwards, and the first gear 17 is disengaged from the second gear 11; then, if the leg lever 6 needs to be adjusted to high pressure, the rocker 12 is rotated clockwise, the rocker 12 drives the first gear 17 to rotate, the first gear 17 moves upwards along the first rack 16, at the moment, the second gear 15 moves upwards synchronously, the leg lever 6 is driven to be lifted through the rotating shaft 1, if the leg lever 6 needs to be adjusted to low pressure, the rocker 12 is rotated counterclockwise, the rocker 12 drives the first gear 17 to rotate, the first gear 17 moves downwards along the first rack 16, at the moment, the second gear 15 moves downwards synchronously, and the leg lever 6 is driven to be lowered through the rotating shaft 1; after the height adjustment is completed, the rocker 12 is released, and the first gear 17 is restored to the fixed state under the spring force to fix the height.

As an alternative embodiment, the second support column 14 is not provided with the second gear 15 and the third rack 20, but with an adjustment structure.

As an alternative embodiment, the second support 14 is not provided with the second gear 15 and the third rack 20, and the sliding block 3 is driven to slide up and down only by the rotating shaft 1.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
