Description

Technical Field

[0001] This utility model relates to the field of pedal machine technology, and in particular to a hydraulically assisted multi-angle adjustable pedal machine trainer. Background Technology

[0002] Leg press machines, as an important fitness tool specifically designed for exercising lower limb muscles, are widely used in professional gyms, fitness studios, and home fitness settings. By simulating leg pedaling movements, they effectively train key muscle groups such as the quadriceps, gluteus maximus, and hamstrings, helping fitness enthusiasts increase lower limb strength, sculpt leg lines, and improve athletic performance.

[0003] Chinese utility model patent CN221981503U discloses a two-foot pedal machine, including a connecting frame and a limiting device. A pedal is slidably connected to the inner wall of the connecting frame, a seat is fixedly connected to the upper surface of the connecting frame, and a backrest is rotatably connected to one end of the seat. A connecting column is fixedly connected to the lower surface of the pedal. The limiting device is disposed on the inner wall of the connecting frame and includes a limiting groove and a limiting block. The limiting groove is formed on the surface of the connecting column, and the limiting block is slidably connected to the surface of the connecting column. This utility model, by setting a limiting device, effectively restricts the limiting block, thus limiting the weight and reducing the possibility of the limiting block easily detaching from the surface of the connecting column when the weight is connected to it during use. This prevents the weight from detaching from the connecting column and failing to apply gravity to the pedal, thereby improving the practicality of the equipment.

[0004] Currently, the connecting frame angle of pedal machines on the market is fixed or simply adjustable. When performing stretching exercises that focus on the quadriceps or strengthening exercises that focus on the gluteus maximus, the angle of the connecting frame and the pedal cannot be adjusted. The fixed angle not only fails to fully activate the target muscle group and affect the training effect, but may also increase the risk of sports injuries to the knee joint, ankle joint and other parts due to improper posture. Therefore, there is a problem that it is not convenient to adjust the pedal angle. Utility Model Content

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a hydraulically assisted multi-angle adjustable pedal machine trainer, including a base 1. An angle adjustment mechanism 2 is hinged to the upper surface of the base 1. A foot pedal 4 is slidably connected to the outer surface of the angle adjustment mechanism 2, and a positioning mechanism 3 is fixedly connected to the outer surface of the angle adjustment mechanism 2. The angle adjustment mechanism 2 includes a rotating frame 205 hinged to the upper surface of the base 1. The foot pedal 4 is slidably connected to the outer surface of the rotating frame 205, and a limiting plate 209 is hinged to the lower surface of the rotating frame 205. A rotating shell 204 is slidably connected to the outer surface of the limiting plate 209, and the rotating shell 204 is hinged to the outer surface of the base 1.

[0032] Specifically, a first hydraulic telescopic rod 208 is fixedly connected to the inner wall of the rotating housing 204. The output end of the first hydraulic telescopic rod 208 is fixedly connected to the outer surface of the limiting plate 209. A connecting rod 203 is fixedly connected to the outer surface of the rotating housing 204. A pointing arrow 202 is fixedly connected to the outer surface of the connecting rod 203. An arc-shaped dial 201 is fixedly connected to the outer surface of the base 1. The outer surface of the pointing arrow 202 is slidably connected to the outer surface of the arc-shaped dial 201. A first control button 210 is fixedly connected to the outer surface of the arc-shaped dial 201. A rotating shaft 206 is rotatably connected to the outer surface of the rotating frame 205. Multiple sets of limiting blocks 207 are fixedly connected to the outer surface of the rotating shaft 206. The outer surface of the limiting blocks 207 is in contact with the outer surface of the foot pedal 4. The outer surface of the sliding plate 306 is slidably connected to the inner wall of the fixed frame 301. A limiting rod 303 is fixedly connected to the outer surface of the sliding plate 306.

[0033] Furthermore, by driving the angle adjustment mechanism 2 through the hydraulic telescopic rod, and with the intuitive indication of the arc-shaped dial 201 and the pointing arrow 202, the adjustment and positioning of the backward pedal angle can be realized. Compared with the traditional mechanical locking adjustment mechanism, it is easier to operate and can meet different training needs.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The positioning mechanism 3 includes a fixed frame 301 fixedly connected to the outer surface of the rotating frame 205. A second hydraulic telescopic rod 305 is fixedly connected to the inner wall of the fixed frame 301. A sliding plate 306 is fixedly connected to the output end of the second hydraulic telescopic rod 305.

[0036] Specifically, a fixed column 302 is fixedly connected to the outer surface of the base 1. Multiple fixed plates 304 are fixedly connected to the inner wall of the fixed column 302, and the outer surface of the fixed plate 304 is in contact with the outer surface of the limiting rod 303. A seat cushion 5 is fixedly connected to the outer surface of the base 1, and a second control button 307 is fixedly connected to the outer surface of the seat cushion 5. The outer surface of the second control button 307 is electrically connected to the outer surface of the second hydraulic telescopic rod 305 through a wire. The hydraulic telescopic rod is based on Pascal's principle, that is, pressure can be transmitted equally in a closed liquid. In the hydraulically assisted multi-angle adjustable pedal trainer, mechanical energy is converted into the pressure energy of hydraulic oil by a hydraulic pump. The hydraulic oil is transmitted in the pipeline. When the hydraulic oil enters the cavity of the hydraulic telescopic rod, the pressure pushes the piston, converting the pressure energy of the hydraulic oil back into mechanical energy, realizing linear reciprocating motion, and thus facilitating the adjustment of the pedal angle.

[0037] Furthermore, the second hydraulic telescopic rod 305 pushes the limit rod 303 to precisely cooperate with multiple sets of fixing plates 304 inside the fixing column 302 to form a rigid locking structure that can withstand the impact force during high-intensity training and prevent accidental angle deviation.

[0038] Working principle: When the user needs to adjust the pedal angle, first press the second control button 307 on the seat 5 to trigger the second hydraulic telescopic rod 305. Its output end drives the sliding plate 306 to slide within the fixed frame 301, causing the limit rod 303 to separate from the fixed plate 304 within the fixed column 302, thus releasing the locking state of the rotating frame 205. Then, press the first control button 210 to start the first hydraulic telescopic rod 208. Its output end pushes the limit plate 209 to slide within the rotating housing 204. Since the rotating housing 204 is hinged to the base 1 and the limit plate 209 is hinged to the rotating frame 205, this action will cause the rotating frame 205 to rotate around the hinge point of the base 1. During the rotation, the rotating housing 204 drives the connecting rod 203 and the pointing arrow 202 to rotate synchronously. The user can accurately observe the rotation angle through the position of the pointing arrow 202 on the arc-shaped dial 201. After adjusting to the target angle, press the second control button 307 again to insert the limit rod 303 into the corresponding fixed plate 304 to complete the angle locking. During training, the user places both feet on the foot pedal 4. The foot pedal 4 is connected to the rotating frame 205 through the pivot 206 and its sliding range is limited by the limit block 207 to ensure the stability of the training process.
