Description

Technical Field

[0001] This invention relates to the technical field of lower limb training devices, and particularly to an adjustable lower limb strength training device. Background Technology

[0002] Lower limb strength refers to the tension and functional capacity generated when the muscles of the lower limbs contract. It is mainly provided by the muscles of the thighs, calves, and buttocks. It is the foundation for completing daily activities and sports movements such as walking, jumping, squatting, and climbing stairs. As a classic lower limb strength training exercise, squatting can effectively exercise the quadriceps, gluteus maximus, and other muscle groups, and is widely used in fitness training, physical training and other fields.

[0003] Based on the above, the equipment currently used for squat training mainly includes barbells, squat racks, and various fixed-track squat machines. Barbell squats require trainees to balance the load themselves, demanding a high degree of proper form. While traditional fixed-track squat machines can constrain the movement trajectory to some extent, they lack a protective mechanism against the trainee's exhaustion. When trainees are exhausted under load and unable to maintain their balance, they often cannot safely release the load on their own, posing a risk of tipping over or being crushed by the equipment. In addition, the flexibility of adjusting parameters such as leg opening distance and support height on conventional training equipment is insufficient, making it difficult to adapt to trainees of different heights and body proportions, thus limiting the standardization and comfort of the training movements. Summary of the Invention

[0004] In view of this, the present invention provides an adjustable lower limb strength training device, which has a load-bearing base, a load-bearing frame, a load-bearing support, a load-bearing side frame, a load-bearing bracket, a load-bearing pillar, and a load-bearing side plate. This solves the problem that the equipment used for squat training mainly includes barbells, squat racks, and various fixed-track squat trainers. Barbell squats require the trainee to balance the load and have extremely high requirements for the standard of movement. Although traditional fixed-track squat trainers can constrain the movement trajectory to a certain extent, they lack a protection mechanism for the trainee's exhaustion state. When the trainee is exhausted under load and cannot maintain body balance, it is often difficult to safely unload the load on their own, which poses a risk of tipping over or being crushed by the equipment. In addition, the adjustment flexibility of parameters such as the leg opening distance and support height of conventional training equipment is insufficient, making it difficult to adapt to trainees of different heights and body proportions, which limits the standardization and comfort of training movements.

Combined with the linkage connection of the binding belt, traction cable, and binding cable, the load of the counterweight plate can be precisely transferred to the trainee's waist. This allows for high-intensity lower limb strength training in conjunction with squatting and standing movements. The training load can be flexibly adjusted by adding or removing counterweight plates as needed. Utilizing the fixed assembly of threaded blocks, locking side blocks, and load-bearing supports, combined with the transmission action of the adjusting screw, the spacing between the two sets of load-bearing footrests can be precisely adjusted to accommodate different trainees' limb sizes. The load-bearing footrests, together with the binding strap, provide standing support and positioning for the trainee. It can forcefully regulate the opening and closing distance of the trainee's legs, avoiding joint damage caused by postural deviation. Relying on the elastic support structure of threaded sleeve, buffer spring and guide block, the load-bearing bracket can achieve elastic sliding limit. When the trainee is exhausted and unable to maintain the standing posture, the load-bearing bracket can drive the load-bearing plate to provide timely protective support for the trainee, effectively avoiding the risk of injury caused by falling due to exhaustion. With the driving action of the lifting cylinder, the mounting bracket and load-bearing plate can be adjusted in height, so that the load-bearing plate can be accurately adapted to the trainee's height and body shape, and the squatting action of the trainee can be standardized and limited, further ensuring the standardization and safety of squat training.
