Description

Technical Field

[0001] The invention relates to the field of training equipment, in particular to a sports equipment training device for upper limb strength training. Background Art

[0002] With the advancement of science and technology and the change of lifestyle, automation technology has gradually replaced traditional physical labor, and humans are experiencing an unprecedented crisis of muscle degeneration. A research report by the World Health Organization pointed out that about 27.5% of adults in the world face the dilemma of decreasing muscle mass year by year due to insufficient daily activities, among which the atrophy of upper limb muscles is particularly significant - from the decline in the stability of the rotator cuff muscles to the general weakening of grip strength, these changes not only lead to body imbalance (such as round shoulders and hunchbacks), but are also closely related to chronic diseases such as cervical spondylosis and periarthritis of the shoulder. In this context, scientific and systematic strength training has become an important way for modern people to rebuild their body functions. As a key link in the human movement chain, the strength level of the upper limbs directly affects cardiopulmonary function, metabolic efficiency and even bone health. Compared with general training of aerobic exercises such as running and swimming, targeted resistance training can accurately stimulate the target muscle groups through mechanical loads.

When used, such a device generally provides resistance through gravity, and performs unidirectional exercise by pushing forward or upward. However, in actual use, users often exert force suddenly to overcome the resistance instantly, thereby achieving the effect of pushing out. However, such force application method is not stable, and the user often relaxes when resetting, and the effect of balanced force and smooth exercise cannot be achieved, thereby causing muscles to become fatigued in a short period of time during the irregular force and relaxation process, and it is impossible to perform exercise scientifically and reasonably.

[0036] Preferably: the pressure regulating assembly of the pressure regulating mechanism 3 includes a pressure regulating valve 34, a pressure regulating switch 36, and an emergency release switch 37. A pressure sensor 33 is installed on the top of the pressure supply cylinder 32. The pressure supply cylinder 32 is a double-bar cylinder, and a resistance piston 321 is arranged at the center. The pressure supply cylinder 32 is divided into an upper chamber and a lower chamber by the resistance piston 321. A pressure regulating valve 34 is installed at the center of the resistance piston 321. The opening and closing size of the pressure regulating valve 34 is controlled by the pressure regulating switch 36, thereby adjusting the resistance size of the oil on both sides when passing through the pressure regulating valve 34, thereby providing resistance size adjustment for the rotating cylinder 31.

[0037] Preferably: a rotating seat 312 is provided inside the rotating cylinder 31, an isolation plate is provided on one side of the rotating seat 312, and a swing block 313 is formed on the other side of the rotating seat 312, and the isolation plate is formed on the inner wall of the rotating cylinder 31, and the rotating cylinder 31 is divided into two chambers by the isolation plate, the rotating seat 312, and the swing block 313, and the two chambers are respectively connected to the first oil supply pipe 351 and the second oil supply pipe 352 of the pressure supply pipe group 35, and the first oil supply pipe 351 and the second oil supply pipe 352 are respectively connected to the upper chamber and the lower chamber of the pressure supply cylinder 32.

[0038] Preferably, the center position of the rotating seat 312 is connected with a rotating main shaft 311 through a key, the rotating main shaft 311 is rotatably connected to the fixed frame 21, and the bottom key of the rotating main shaft 311 is connected to the swing frame 22.

[0039] Preferably, the voltage regulating switch 36 and the emergency release switch 37 are connected to the inner side surface of the swing frame 22 by screws.

[0040] Preferably: one end of the piston part of the hand pressure cylinder 44 is connected to the arm support pad 41 by bolts, the cylinder body part of the hand pressure cylinder 44 is connected to the swing frame 22 by bolts, a sliding variable resistor 45 is installed inside the swing frame 22 corresponding to the part of the hand pressure cylinder 44, and a hand release groove 43 is provided on the swing frame 22 corresponding to the top position of the arm support pad 41.

[0041] Preferably, the swing frame 22 takes the rotation main shaft 311 as the rotation axis, and the rotation angle of the swing frame 22 is 0° to 90°.

[0042] Preferably, the sliding variable resistor 45, the pressure regulating switch 36, the emergency release switch 37, the pressure regulating valve 34, and the pressure sensor 33 are connected via electrical signals.

[0043] Preferably, the overall structure of the outer support frame mechanism 1 is made of steel.

[0044] Preferably, the outside of the arm support pad 41 is a steel plate wrapped with a foam pad, and the external exposed parts of the external support frame mechanism 1 are all provided with protective pads.

[0045] Working principle: The user controls the opening of the pressure regulating valve 34 through the pressure regulating switch 36 according to the intensity of the exercise required, thereby controlling the speed of the oil passing between the two chambers inside the pressure supply cylinder 32, and then controlling the resistance when the oil pressure passes through, and reversely providing a constant resistance for the rotating cylinder 31;

[0046] When the user uses it, he holds the top of the arm support pad 41 with his hands, and both arms apply force to buckle inward at the same time. At this time, because the rotating main shaft 311 transmits the torque to the swing block 313 through the rotating seat 312, the swing block 313 overcomes the oil pressure of the two chambers inside the rotating oil cylinder 31. The two chambers inside the two synchronous rotating oil cylinders 31 are connected to the two chambers inside the pressure supply cylinder 32 through the first oil supply pipe 351 and the second oil supply pipe 352 respectively. The greater the resistance of the pressure regulating valve 34, the greater the resistance fed back to the rotating seat 312, the rotating main shaft 311 and the swing frame 22, and the user overcomes the resistance to perform the buckling action;

[0047] When the inner buckle is completed, the swing frame 22 needs to be reset. In the conventional equipment, because the gravity is used, the user tends to relax and the swing frame 22 automatically resets. In this solution, if it needs to be reset, the user needs to pull the arm support pad 41 outward to overcome the resistance inside the rotating cylinder 31 in the same way. In this way, in one cycle, both the inner buckle process and the outer expansion process can be exercised, and in the overall rotation process, the force is more stable due to the transmission of oil;

[0048] And according to the way the elbow area of ​​the human body applies force, when the arm exerts force, the elbow and wrist will also exert force, then the arm support pad 41 rotates with the bottom arm shaft 42 as the axis, and at the same time the hand pressure cylinder 44 provides reverse resistance for the arm support pad 41, and can also provide reverse resistance and range of motion for the swing of the elbow. When the elbow hand pressure cylinder 44 retracts more, the sliding variable resistance plate 45 detects that the sliding distance of the hand pressure cylinder 44 is longer, indicating that the arm and elbow are exerting force, thereby performing effective recording and feedback.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
