Description

Technical Field

[0001] The invention relates to the technical field of sports equipment, in particular to a sports leg-pressing training device. Background Art

[0002] During sports training, dance training and other activities, athletes or trainees generally need to stretch their limbs before training to prevent limb strain and other phenomena during training. They will use leg stretching training equipment to achieve leg stretching exercises or training. Therefore, they need to use leg stretching equipment for training. Leg stretching can exercise the stretching ability of leg ligaments and is the basic skill of various sports. Leg stretching requires persistent practice to maintain good results.

[0003] When athletes are doing leg stretching, the contact between their legs and the device is not close enough, and their legs easily slide to the sides, causing their center of gravity to become unstable and detach from the device, making it impossible to perform effective leg stretching training. Summary of the invention

[0004] The object of the present invention is to provide a leg press training device for sports to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a sports leg-pressing training device comprises a bottom plate, a support frame is symmetrically installed on the top of one side of the bottom plate, a driving motor is installed on the bottom of one side of the support frame, a rotating rod is installed on the output end of the driving motor, a connecting belt is installed inside the support frame, a transmission member is arranged between the rotating rod and the connecting belt, a leg-pressing column is slidably installed on the inner side of the support frame, a cushion block is symmetrically installed inside the leg-pressing column, a connecting rod is slidably installed on the bottom end of the leg-pressing column, an extrusion member is arranged between the cushion block and the connecting rod, an extrusion rod is slidably installed on the top of the leg-pressing column, an extrusion pad is installed on one end of the extrusion rod, and a contraction member is arranged between the extrusion rod and the extrusion pad; Screw rods are symmetrically installed inside the base plate, a control frame is sleeved on the middle part of the outer side of the rotating rod, a rotating part is arranged between the rotating rod and the screw rod, a sliding box is installed in the middle part of the top end of the base plate, a contraction spring is installed on one side of the sliding box, a placement box is connected to one end of the contraction spring, a sleeve part is arranged between the screw rod and the sliding box, a support plate is installed on the top end of the support frame, a contraction cylinder is slidably installed on the bottom end of the support plate, and a stretching part is arranged inside the contraction cylinder.

[0006] Preferably, the transmission member includes a rolling column symmetrically installed on the top of the inner side of the support frame, the connecting belt is rollingly connected to the outside of the rolling column, one end of the connecting belt is connected to the outside of the rotating rod, and the other end of the connecting belt is connected to a sliding member.

[0007] Preferably, the sliding member comprises a sliding rod connected to one end of the connecting belt.

[0008] Preferably, the extrusion member includes a cross rod installed at the bottom end of the pad, one end of the connecting rod is internally rotatably connected to the cross rod, the connecting rod is slidably installed in the slide groove, one end of the connecting rod is connected to the side of a compression spring, and the other end of the connecting rod is internally rotatably connected to a connecting member.

[0009] Preferably, the connecting member includes a connecting rod installed inside one end of the connecting rod, and the connecting rod is sleeved on the middle part of the outer side of the pillar.

[0010] Preferably, the contraction member comprises an extrusion rod slidably mounted in a top slide groove, and the extrusion rod is rotatably mounted on the top of the pillar.

[0011] Preferably, the rotating member includes bevel gears rotatably mounted on both ends of the control frame, one end of the screw rod is mounted with a bevel gear, and the bevel gears at both ends of the control frame are respectively meshed and connected with the bevel gear at one end of the screw rod.

[0012] Preferably, the socket connector comprises a sleeve mounted on the sliding box, and the sleeve is threadedly connected to the outer side of the screw rod.

[0013] Preferably, the stretching member comprises a torsion spring installed inside the shrinking tube, the outer side of the torsion spring is wrapped with a telescopic belt, and a handle is installed at the bottom end of the telescopic belt.

[0014] Preferably, a sponge pad is installed inside the placement box.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: First, the present invention drives the bottom ends of the cross rods to separate to both sides through the downward pressure of the pad block, and drives the connecting rod to slide in the bottom slide groove at the same time. During the sliding process of the connecting rod, the compression spring will be stretched, and at the same time, the bottom end of the connecting rod will be driven to move outward. The connecting rod is sleeved on the outside of the pillar, and the outward force of the bottom of the connecting rod is converted into an inward force of the top of the connecting rod. The top of the connecting rod drives the extrusion rod to push the extrusion pad. At the same time, two extrusion rods are installed on the top of the connecting rod, so that the extrusion pad can be completely fitted with the athlete's calf, preventing the athlete's legs from sliding between the device when stretching their legs, resulting in separation from the leg-pressing column. At the same time, the pad block provides support force during the athlete's stretching process, and the stretching process is more comfortable.

[0016] Second, the driving motor of the present invention drives the connecting belt to contract or extend through the rotating rod, and at the same time, the connecting belt is rollingly connected to the outside of the rolling column, so that the contraction or extension process is smoother. During the contraction or extension process of the connecting belt, the leg-stretching column will be driven to move vertically through the sliding rod. The sliding rod slides inside the supporting frame, so that the leg-stretching column will not swing during the vertical movement. At the same time, the leg-stretching column can be adjusted to the most comfortable stretching height according to different athletes.

[0017] Third, the present invention drives the bevel gear to mesh with one end of the screw rod through the control frame, driving the screw rod to rotate. During the rotation of the screw rod, the sliding box and the placement box are driven to slide to one side through the sleeve, and at the same time, the athlete's other leg is driven to stretch. At the same time, in conjunction with the leg-pressing column, the athlete's legs can be stretched at the same time, shortening the time for the athlete to do stretching exercises. At the same time, the bevel gear on the outside of the rotating rod is controlled by the control frame, and the bevel gear is driven by the control frame to move horizontally, so that the bevel gear is not meshed and connected with one end of the screw rod. The driving motor only drives the leg-pressing column to move vertically, which increases the application range of the device and has more controllability. The athlete grasps the handle and drives the telescopic belt to contract or extend through the torsion spring, which can provide more support force during the athlete's stretching exercises.
