A leg trainer

Abstract

This utility model relates to the field of fitness equipment, specifically to a leg trainer, including a mounting base. The mounting base houses two sets of hydraulic rods. The lower end of the cylinder of each hydraulic rod is fixedly connected to the base. Foot pedals are mounted on the upper end of the movable rod of each hydraulic rod. The mounting base is equipped with two sets of hydraulic control components, each corresponding to a hydraulic rod. These hydraulic control components actively control the extension and retraction of their respective hydraulic rods, causing different sets of hydraulic rods to extend and retract alternately. The user places both feet on the two foot pedals and then controls the extension and retraction of the corresponding hydraulic rods through the hydraulic control components. The alternating extension and retraction of the two hydraulic rods, combined with the angle between the hydraulic rods and the horizontal plane, simulates a mountain climbing motion, effectively exercising the user's lower limbs. It provides passive leg training and can be used for rehabilitation exercises. The structure is relatively simple and the effect is good.

Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, specifically to a leg trainer. Background Technology

[0002] A stepper is a fitness machine that allows users to repeatedly climb stairs, which can enhance the function of the cardiovascular system and fully exercise the thigh and calf muscles.

[0003] Most existing stepper machines provide training by actively resisting resistance. The resistance source is mostly from hydraulic cylinders. Moreover, most hydraulic cylinders are merely resistance components and cannot independently generate support and power. These types of stepper machines cannot achieve passive training and are not very suitable for rehabilitation training. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a leg training device.

[0005] The technical solution of this utility model is as follows: This utility model provides a leg trainer, including a mounting base. The mounting base is equipped with two sets of hydraulic rods. The lower end of the cylinder of the hydraulic rod is fixedly connected to the base. A foot pedal is installed on the upper end of the movable rod of the hydraulic rod. The mounting base is provided with two sets of hydraulic control components that correspond one-to-one with the hydraulic rods. The hydraulic control components actively control the extension and retraction of the corresponding hydraulic rods, so that the hydraulic rods of different sets extend and retract alternately.

[0006] Furthermore, the foot pedal is hinged to the upper end of the movable rod of the hydraulic rod via a connecting rod.

[0007] Furthermore, the hydraulic control component includes a piston tube, which is connected to the cylinder body of the corresponding hydraulic rod. A piston block is installed inside the piston tube. The piston tube is connected to the inner end of the piston rod. The outer end of the piston rod extends to the outside of the piston tube. The outer end of the piston rod is connected to the drive device, which drives the piston rod to reciprocate along the axial direction of the piston tube.

[0008] Furthermore, the drive device includes a lead screw and a motor. The two ends of the lead screw are connected to two piston rods respectively. A sleeve is threaded onto the lead screw, and the sleeve is connected to the mounting base through a bearing seat. The driven wheel on the sleeve is connected to the driving wheel of the motor's output shaft through a transmission assembly.

[0009] Furthermore, the transmission component is a belt pulley assembly.

[0010] Furthermore, the leg trainer also includes a handrail assembly.

[0011] Furthermore, the handrail assembly includes a bracket, the lower side of which is connected to a mounting base, and the handrail is mounted on the upper side of the bracket.

[0012] Furthermore, each set of hydraulic rods is equipped with two parallel hydraulic rods, and the upper ends of the movable rods of the hydraulic rods in the same set are connected by a connecting block. The connecting rod is hinged to the connecting block at the upper end of the movable rod of the hydraulic rod.

[0013] Furthermore, the hydraulic rod has a certain angle with the horizontal.

[0014] The beneficial effects achieved by this utility model are as follows: When using this invention, the user places both feet on the two foot pedals respectively, and then controls the extension and retraction of the corresponding hydraulic rods through the hydraulic control components. The hydraulic rods on both sides extend and retract alternately. Combined with the setting of the hydraulic rods having a certain angle with the horizontal, it can simulate mountain climbing movements, exercise the user's lower limbs, passively train the legs, and carry out rehabilitation training. The structure is relatively simple and the effect is good. Attached Figure Description

Detailed Implementation

[0016] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0017] like Figures 1-6 As shown, this utility model provides a leg training device.

[0018] Example 1: The leg trainer includes a mounting base 1. The mounting base 1 is equipped with two sets of symmetrically arranged hydraulic rods 2. The lower end of the cylinder body 201 of the hydraulic rod 2 is fixedly connected to the base 1. The hydraulic rod 2 is preferably set at a certain angle to the horizontal. A foot pedal 3 is installed on the upper end of the movable rod 202 of the hydraulic rod. The foot pedal 3 is hinged to the upper end of the movable rod 201 of the hydraulic rod 2 through a connecting rod. The mounting base is equipped with two sets of hydraulic control components 3 that correspond one-to-one with the hydraulic rods. The hydraulic control components control the extension and retraction of the corresponding hydraulic rods.

[0019] like Figure 3As shown, one embodiment of the hydraulic control assembly includes a piston tube 301, which is connected to the cylinder 201 of the corresponding hydraulic rod 2. A piston block 302 is provided inside the piston tube 301. The piston tube 302 is connected to the inner end of the piston rod 303. The outer end of the piston rod 303 extends to the outside of the piston tube. The outer end of the piston rod is connected to the drive device 4. The drive device 4 drives the piston rod to reciprocate along the axis of the piston tube. The piston rod pushes the corresponding piston to move. The piston block can deliver the hydraulic oil in the corresponding piston tube to the corresponding hydraulic rod, thereby controlling the extension of the movable rod 202. Similarly, the shortening of the movable rod can also be controlled.

[0020] like Figure 1 As shown, the drive device includes a lead screw 401, with both ends of the lead screw 401 connected to two piston rods respectively. A sleeve 402 is threaded onto the lead screw, and the sleeve 402 is connected to the mounting base 1 via a bearing seat. The driven wheel on the sleeve 402 is connected to the driving wheel of the output shaft of the motor 403 via a transmission assembly. The transmission assembly can be a pulley assembly, a sprocket assembly, or a gear assembly, etc. By driving the sleeve to reciprocate, the motor can control the lead screw to reciprocate along its length, thereby driving the piston block to reciprocate, and thus controlling the extension and retraction of the movable rod.

[0021] Example 2, as Figure 6 As shown, the leg trainer also includes a handrail assembly 5, which includes a support 501. The lower side of the support is connected to the mounting base, and the upper side of the support is equipped with a handrail 502. Through the handrail assembly, the user can better maintain the stability of the body during training.

[0022] like Figure 6 As shown, each set of hydraulic rods has two parallel hydraulic rods. The upper ends of the movable rods of the hydraulic rods in the same set are connected by connecting block 6. The connecting rod 4 is hinged to the connecting block at the upper end of the movable rod 201 of the hydraulic rod 2. This design can improve the stability of the foot pedal support.

[0023] Working principle: The user places both feet on the two foot pedals respectively, and then controls the extension and retraction of the corresponding hydraulic rods through the hydraulic control components. The two hydraulic rods extend and retract alternately. Combined with the setting of the hydraulic rods having a certain angle with the horizontal, it can simulate the action of climbing, exercise the user's lower limbs, passively train the legs, and carry out rehabilitation training. The structure is relatively simple and the effect is good.

[0024] The above-described embodiments of the utility model do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
