Optionally, the locking assembly 2 locks the lifting assembly 1 to limit the lifting assembly 1 to perform a lifting motion but not a lowering motion. The locking assembly 2 unlocks the lifting assembly 1 to release the limitation that the lifting assembly 1 cannot do descending movement.

For example, the stopping pawl 211 is provided with a plane located on a side of the stopping pawl 211 facing the supporting frame 20 and a slope facing away from the plane, when the stopping pawl 211 is stopped at the gear set 4, the rotation of the gear portion 41 is limited by the plane where the stopping pawl 211 contacts the gear portion 41, that is, when the gear portion 41 contacts the plane of the stopping pawl 211, the force applied by the gear portion 41 to the stopping pawl 211 is perpendicular to the plane, so that the force applied by the gear portion 41 to the stopping pawl 211 cannot drive the stopping member 21 to slide along the length direction thereof, and the rack portion 112 cannot move downward. When the rack portion 112 moves up, the gear portion 41 slides in contact with the inclined surface of the locking pawl 211, the inclined surface of the locking pawl 211 is influenced by the component force of the gear portion 41, and the stopper 21 slides along the length direction thereof, so that when the rack portion 112 moves up, the locking pawl 211 does not limit the rack portion 112 to move up, thereby realizing the function that the rack portion 112 can only move up but can not move down.

After adjusting the angle between support frame 20 and the body frame 10, under the prerequisite of not unblock gear train 4, gear train 4 can increase the angle between support frame 20 and the body frame 10 next to in order to satisfy the exercise demand, on the contrary, under the prerequisite of not unblock gear train 4, when the user leans on support frame 20, rack portion 112 can't be the descending movement, in order to firmly support the user, safe and reliable stabilizes, factor of safety is high. That is, when a user exercises by leaning on the stand 20, the rack portion 41 is not lowered by the force applied to the stand 20 by the user, and the stand 20 can provide a stable support for the user. When the user wants to enlarge the contained angle between the support frame 20 and the main frame 10, the rack part 41 can be lifted by applying upward acting force to the support frame 20 or operating the hand-operated turntable 51, and the support frame 20 can be automatically locked after being adjusted to a desired position, so that the adjustment mode is quick, safe and convenient.

When the locking pawl 211 unlocks the gear train 4, the restriction that the rack 112 cannot move down is released, and the rack 112 can move up or down.

The beneficial effect of this application is: unlike the prior art, the present application discloses an adjustment mechanism 30 and exercise device. Adjust the angle between support frame 20 and the body frame 10 through lifting unit 1, and through locking assembly 2 locking or unblock lifting unit 1, with inject the contained angle between support frame 20 and body frame 10, or remove the contained angle of injecing between support frame 20 and body frame 10, it is convenient, swift to adjust, with the convenience of promoting the use, and inject the contained angle between support frame 20 and body frame 10 through locking assembly 2, difficult production is not hard up or rocks, safety and reliability, in order to promote safe coefficient of use.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
