Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

In order to make those skilled in the art better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to the accompanying drawings 1 to 3 of the description, FIG. 1 is a schematic structural diagram of the squat training apparatus for exercising the spine provided by the embodiment of the application, and FIG. 2 is the squat training apparatus for exercising the spine provided by the embodiment of the application. The schematic diagram of the standing position and FIG. 3 are the schematic diagrams of the squat training apparatus for exercising the spine provided by the embodiment of the application in the squat position, including: a base 1, and a first column 2 and a second column 3 are vertically arranged on the base 1 ; One side of the first column 2 is connected with an upper limb driving component 4 through the first tilting mechanism, and the upper limb driving component 4 can tilt relative to the first column 2 . One side of the above-mentioned second column 3 is connected with a lower limb follower part 5 through a second tilting mechanism, the lower limb follower part 5 is correspondingly arranged below the upper limb driving part 4, and the lower limb follower part 5 can tilt relative to the second column. . The first tilting mechanism and the second tilting mechanism are connected and driven by the connecting rod 6. When in use, the user stands on the lower limb follower part 5 and holds the upper limb driving part 4, and bends the knees and sits on the hips to drive the arms to pull down. When the upper limb drive part 4, the link 6 transmits the motion to the lower limb follower part 5, so that the upper limb drive part 4 and the lower limb follower part 5 are close to each other. Stand up to half squat to squat, then stretch your back spine. Compared with the existing equipment, the present application limits the forward tilt of the user's shoulders, which is equal to receiving the reaction force of the equipment during the squatting process, so that the upper end of the thoracic vertebra connecting the neck and shoulders is forced to the rear of the body, while the lower end of the thoracic vertebra at this time is in the middle. Due to the joint effect of the lumbar spine, the upper and lower ends of the thoracic spine are forced backward at the same time. In order to maintain the balance of the body and not fall backward, the muscles around the thoracic spine can only exert force forward, especially The bearing force of the middle thoracic vertebrae is particularly concentrated, so that the thoracic curve of the kyphotic curve exerts forward force, that is, the force against the physiological bending direction.

In this way, the upper limbs are driven to stretch and contract back and forth, and the body is used to pull the body without the aid of external objects. In this way, it not only reduces the load on the legs and hips, but also helps to relax and stretch the spine.

Further, the above-mentioned first tilting mechanism comprises: two first lever rods 7 arranged in parallel and of equal length, one end of the first lever rod 7 is rotatably connected to the first column 2, and the other end is rotatably connected to the upper limb driving component 4. Because the upper limb driving part 4 is arranged in parallel with the first column 2, and the four rotation connection points of the two first columns 2 can be rotated, a movable parallelogram connection relationship is formed, so that the upper limb driving part 4 Can move relative to the first column 2 . The user can exercise by using the upper limb grasping the upper limb driving part 4 to provide driving force.

The second tilting mechanism includes: a second lever arm 8 and a third lever lever 9 that are parallel to each other; the middle section of the second lever lever 8 is rotatably connected to the top of the second column 3, and the third lever lever One end of 9 is rotatably connected to the side of the second column; the other end of the third lever 9 and the end on the same side of the second lever 8 are rotated and connected to the lower limb follower 5 at the same time. The other end is connected to the middle section of the first moment arm rod 7 through the connecting rod 6 . Similar to the first tilting mechanism, the second tilting mechanism forms a movable parallelogram connection between the lower limb follower 5 and the second upright column 3 . The motion transmission of the upper limbs realizes the approach or distance of the upper limb driving part 4 and the lower limb follower part 5 . It is foreseeable that the pivot point of the first tilt mechanism is the pivotal connection point of the first lever 7 and the first upright column 2 near the bottom, and its turning radius is the arm length of the first lever 7, and the upper limb driving part 4 The motion trajectory is circular arc. The pivot point of the second tilting mechanism is the rotational connection point between the middle section of the second lever arm 8 and the top end of the second column 3 , and its turning radius is the arm length of the third lever lever 9 , and the movement track of the lower limb follower part 5 Also arcuate. Because the movements of the two are arc trajectories, and they both run up and down, there are displacement variables in the front and rear directions, and they run synchronously, so the displacement variables of the upper limb driving part 4 and the lower limb follower part 5 in the front and rear directions are passed through The fulcrum position can be set and the value of the lever support to the spine can be optimized.

Further, the above-mentioned lower limb follow-up component 5 includes: a third column 10, a foot support 11 and a knee support 12; the third column 10 is arranged in parallel with the second column 3, and the second lever 8 and the third lever 9 rotate It is connected to the third upright post 10 ; the foot support 11 and the knee support 12 are both arranged on the side of the third upright post 10 away from the second upright post 3 .

The upper section of the third upright column 10 is connected with a knee support 12, and the knee support 12 is designed in a U shape and is used to limit the displacement of the knee in the front, left and right directions. In the movement trajectory from standing up to squatting, when the forward movement of the knees is limited, the subsequent movement trajectory takes the knee as the origin and the thigh and femur as the radius, so that the pelvis moves backwards from top to bottom in a circular arc. Drive the lumbar curve to the rear to bulge and bend. Because the knees no longer move forward and unload the force, the femur can only exert force on the rear pelvis, which is equivalent to increasing the movement radius and movement trajectory, that is, the lumbar curve is bent backward as much as possible. Moreover, this bending is not a "fuzzy bending", but under the support of the femur, in the process of squatting, the lumbar vertebrae are subjected to lateral force from front to back, and from bottom to top. This is the femur. Brings leveraged support to stretch the lumbar vertebrae. In this way, the lumbar curve of the lordotic curve has a force in the opposite direction of the physiological curve.
