Description

Technical Field

[0001] This invention belongs to the field of training equipment technology, specifically relating to a physical training device suitable for various groups of people and its usage method. Background Technology

[0002] Physical fitness is the basic motor ability of the human body, manifested through athletic qualities such as strength, speed, endurance, coordination, flexibility, and agility. It is an important component of an athlete's competitive ability. The level of physical fitness is closely related to the morphological and functional characteristics of the human body.

[0003] Based on the performance and role of physical fitness in different populations, physical fitness can be divided into two levels: health fitness and competitive fitness. Health fitness refers to the functional capabilities of organ systems essential for any population and forms the foundation of competitive fitness. Competitive fitness, on the other hand, is the further development of physical capabilities required for competitive sports, built upon the foundation of health fitness.

[0004] In actual physical education, the development of athletes' competitive physical fitness is influenced by a variety of factors. Innate physical fitness is acquired through genetic effects, while acquired physical fitness is mainly improved through effective physical training. At the same time, it can also be developed in a suitable geographical environment and a favorable social environment.

[0005] The direct task of physical training is to improve athletes' athletic qualities according to the needs of competition in various events. To this end, it is also necessary to improve athletes' functional condition and strive to make their physical form suitable for the requirements of the sport.

[0006] During physical activity, the human body's energy supply is achieved through the coordinated work of the three major energy metabolism systems, as well as the nervous, skeletal, and muscular systems. The speed, strength, endurance, coordination, agility, and flexibility required for training and competition are achieved by improving the athlete's energy metabolism, nervous, muscular, and skeletal systems to meet the demands of the sport. Every sport has specific requirements for the function of these systems; therefore, the first step in physical training is to clarify the athlete's activity patterns during competition and, based on this, how to improve the athlete's energy metabolism capacity and the function of their nervous, skeletal, and muscular systems.

[0007] Authorization publication number "CN114849135A", publication date August 5, 2022, describes a multifunctional athletic long-distance running teaching physical training device and its usage method, relating to the field of athletic physical training. The device includes a training platform, and hurdle components, leg training components, resistance training components, and arm training components mounted on the platform. The hurdle component includes a rotating shaft and hurdles. The training platform has several equidistantly arranged hurdle slots, each containing several rotating shafts. The hurdles are fixedly connected to the rotating shafts within the slots. This method allows for easier equipment inspection, adjustment, training, and equipment cleanup. It provides better control over training intensity, and as training time gradually increases, the training process and speed also gradually increase, resulting in higher training efficiency. Furthermore, the entire device is interconnected, ensuring safety and reliability, achieving multiple functions, and improving usability.

[0008] The aforementioned device incorporates hurdle training, leg training, resistance training, and arm training components. The hurdle training component trains participants in hurdles, the leg training component primarily trains leg muscles, the resistance training component simulates resistance to the body, focusing on sprinting towards the finish line when stamina is low, and the arm training component trains arm strength. These components work together, offering diverse training options and allowing multiple participants to train simultaneously, reducing limitations and improving usability. However, the leg training is adjusted solely by changing the weight-bearing parts of the legs, and it only involves cycling-like leg movements. It cannot provide seated cycling training. Furthermore, in seated cycling training, different participants have varying leg lengths; using the same length would prevent effective training for each individual due to leg differences. Additionally, the training intensity cannot be controlled; as training time increases, the training process and intensity cannot be progressively increased, resulting in low training efficiency. Summary of the Invention

[0009] The purpose of this invention is to provide a physical training device and its usage method suitable for various groups of people. It has good training effect. However, it is difficult to control the intensity of training. As the training time is gradually extended, the training process and intensity cannot be gradually increased accordingly, resulting in low training efficiency.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A physical training device suitable for a variety of people, comprising:

[0012] main body;

[0013] The mounting slot is located at the upper end of the main body;

[0014] A fixing plate is connected to one side of the upper end of the main body by bolts and threads. A seat is provided on the fixing plate, and a first mounting plate is provided on the other side of the upper end of the main body.

[0015] The adjustment mechanism includes a circular groove, a lead screw, a lead screw nut, a connecting assembly, and a driving component. The circular groove is located on the side of the main body. The lead screw is rotatably connected to the circular groove, and the lead screw nut is slidably connected to the mounting groove, matching the lead screw. The upper end of the lead screw nut is connected to a first mounting plate, on which a leg training section is provided.

[0016] The connecting assembly is disposed in the mounting groove, and the driving component is disposed on the side end of the lead screw to realize the rotation of the lead screw; the connecting assembly includes a guide rod, a first sprocket and a first toothed chain, the guide rod is rotatably connected in the mounting groove, the first sprocket is fixedly connected to the side ends of the lead screw and the guide rod respectively, the first sprocket is meshed and rotatably connected to the circumferential surface of the two first sprockets, and the guide rod passes through the lead screw nut and rotates in the lead screw nut.

[0017] The above configuration, through the adjustment mechanism, allows for better connection of the lead screw via the circular groove during operation, ensuring better engagement between the lead screw nut and the lead screw nut. This facilitates easier adjustment of the first mounting plate during use. The connection of the connecting assembly and the drive component allows the drive component to rotate one end of the lead screw, which in turn drives the guide rod and lead screw to rotate via the first toothed chain of the connecting assembly. The rotation of the lead screw causes the lead screw nut to move along the length of the mounting groove, allowing for convenient adaptive adjustment of the distance between the leg training section and the seat according to different users' leg lengths, thereby improving training effectiveness. It also allows for control of training intensity for different users, increasing training efficiency. Furthermore, a guide rod is parallel to one side of the lead screw. Since the guide rod passes through the lead screw nut, it guides the lead screw nut during movement, ensuring reliable movement.

[0018] Furthermore, the driving component includes a motor, a second sprocket, a third sprocket, and a second toothed chain. The motor is fixedly connected to the side end of the main body, the second sprocket is fixedly connected to the other side end of the lead screw, the third sprocket is fixedly connected to the output end of the motor, and the second toothed chain is rotatably connected to the circumferential surfaces of the second sprocket and the third sprocket.

[0019] The above configuration, by placing the motor at the lower end, facilitates the installation of the drive components. The motor drives the second toothed chain, which in turn drives the lead screw, making the lead screw movement more reliable.

[0020] Furthermore, the leg training section includes a second mounting plate, a rotating rod, and a second counterweight plate. The upper end of the first mounting plate is connected to the second mounting plate by bolts and threads. A mounting platform is provided on the second mounting plate. A rotating rod is rotatably connected to the side end of the second mounting plate. The side end of the rotating rod is connected to the second counterweight plate by bolts and threads. A mounting bracket is fixedly connected to the mounting platform and the closer end of the second mounting plate. An S-shaped rod is rotatably connected to the side end of the second counterweight plate. A foot pedal is rotatably connected to the side end of the S-shaped rod.

[0021] The above setup involves threadedly connecting the second counterweight plate to the device using bolts. This allows the device to be easily replaced according to different training needs during training, enhancing the training effect on trainees and improving the overall performance of the device. The bolted connection between the fixing plate and the seat facilitates easier disassembly and replacement of the seat, further improving the device's performance.

[0022] Furthermore, a seat is connected to the upper end of the fixing plate by bolts and threads. A headrest is provided at the upper end of the seat, and an adjustment rod is provided at the lower end of the headrest. The adjustment rod matches the seat.

[0023] The above settings allow users to adjust the seat height and tilt angle according to their own circumstances.

[0024] Furthermore, a circular rod is provided on the side end of the main body, a bracket is fixedly connected to the side end of the circular rod, a placement plate is fixedly connected to the side end of the bracket, and a handle is fixedly connected to the upper end of the placement plate.

[0025] The above setup, with the handle connected via a bracket, is simple in structure and convenient for users to grip during training.

[0026] Furthermore, a leg stretching training section is provided at the lower end of the main body. The leg stretching training section includes a rectangular block, a connecting plate, and a mounting frame. A rectangular block is fixedly connected to the side end of the main body. A cross groove is opened at the side end of the rectangular block. A limit block is fixedly connected to the lower end of the main body. A cross slider is slidably connected in the cross groove. A connecting plate is fixedly connected to the side end of the cross slider. A mounting frame is rotatably connected to the side end of the connecting plate. A locking rod is movably inserted between the connecting plate and the limit block.

[0027] With the above setup, when leg stretching exercises such as leg extension are needed, push the mounting bracket to match the cross slider with the cross groove, and adjust the position of the mounting bracket. After adjusting to the appropriate position, pass the locking rod through the connecting plate and engage it with the limiting block to realize the leg extension exercise and improve the diversity of training.

[0028] Furthermore, the lower end of the mounting bracket is connected to a first counterweight plate by bolt thread, and a sleeve rod is fixedly connected to the side end of the mounting bracket, with a protective cotton sleeved to the side end of the sleeve rod.

[0029] The above settings, by setting the first weight plate, make it easy to achieve different levels of training by changing different weight plates.

[0030] Furthermore, a base is fixedly connected to the lower end of the main body.

[0031] The above design, with a base fixedly connected to the lower end of the main body, facilitates easier connection to external components during use, making the device more stable.

[0032] The present invention also provides a method for using a physical training device suitable for various groups of people, comprising the following steps:

[0033] S1: First, when leg training is needed, different intensity training can be achieved by changing the second counterweight plate with different weights. Then, by starting the motor, the third sprocket and the second toothed chain are engaged through the second toothed chain. At this time, the side ends of the lead screw and the guide rod are engaged with the first toothed chain through the first sprocket, causing the guide rod and the lead screw to rotate, which in turn causes the lead screw nut to slide. At this time, the upper end of the lead screw nut is connected to the second mounting plate through the bolt thread for position adjustment. After adjusting to the appropriate position, adjust the height of the adjusting rod so that the headrest matches the trainee's neck and the feet match the foot pedals. At this time, leg pedaling can be performed for leg training.

[0034] S2: When it is necessary to change the training method, the lead screw can be rotated by starting the motor, so that the position of the lead screw nut can be adjusted to the far right. Then, the cross slider can be matched with the cross groove through the sliding mounting bracket, and the position can be adjusted with the mounting bracket. After adjusting to the appropriate position, the locking rod can be inserted through the connecting plate and engaged with the limit block. At this time, the trainee can replace the first counterweight plate according to the training intensity and place the legs on the protective cotton. The trainee sits on the chair and matches the hands with the handles and stretches the legs for leg training.

[0035] The above method, by setting an adjustment mechanism, allows for better connection of the lead screw through the circular groove during device operation, ensuring better engagement between the lead screw nut and the lead screw nut. This facilitates easier adjustment of the first mounting plate during use. Through the connection of the connecting assembly and the drive component, the drive component rotates one end of the lead screw, which in turn drives the guide rod and lead screw to rotate via the first toothed chain of the connecting assembly. The rotation of the lead screw causes the lead screw nut to move along the length of the mounting groove. This allows for convenient adaptive adjustment of the distance between the leg training section and the seat according to the leg length of different users, thereby improving training effectiveness. Furthermore, it allows for control of training intensity for different users, improving training efficiency. The adjustment method is simple and reliable. Additionally, adjusting the position of the connecting plate allows for adjustment of leg extension movements, enhancing training diversity and efficiency. Attached Figure Description
