[0057] The terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second", "third" can explicitly or implicitly include one or more of the features.

[0058] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0059] As attached Figures 1 to 4 As shown in an illustrative embodiment of the triceps trainer of this utility model, the triceps trainer includes a base 1, two power arms 2, two swing arms 3, and two limiting rods 5. A seat 6 is provided on the base 1. (See reference) Figure 3 The first frame 11, the second frame 12, and the third frame 13 of the base 1 form a stable triangular structure. (See attached diagram.) Figures 1 to 4 A detailed explanation of the specific structure of the triceps trainer is provided.

[0060] The second lever arm 2 is rotatably mounted on the base 1. The lever arm 2 is mounted on the top of the first frame 11 of the base 1. The second lever arm 2 is connected to a resistance structure. The resistance mechanism can be a counterweight unit such as a counterweight block or a counterweight plate installed on the outside of the swing arm through a counterweight rod on the outside of the swing arm, or it can be an insert-type counterweight unit connected to the handle through a rope inside the swing arm.

[0061] The first end of the two swing arms 3 is rotatably connected to the end of the two power arms 2 near the seat 6, and has a first pivot point A. The second end of the two swing arms 3 extends upward and is equipped with a handle bar 4. An auxiliary counterweight is provided at the end of the power arm 2 away from the seat 6 to provide a balancing force so that the trainee can more easily push the handle bar 4.

[0062] The first ends of the two limiting rods 5 are rotatably connected to the two swing arms 3 respectively, and have a second pivot point B. The second ends of the two limiting rods 5 are rotatably connected to the base 1. By controlling the rotation range of the second ends of the limiting rods 5, the swing amplitude of the swing arm 3 is made to be within a preset swing amplitude range.

[0063] In this embodiment, the preset swing amplitude range is approximately 5 to 10 centimeters for the swing arm 3 to move forward or backward based on its current position. Optionally, in this embodiment, it is 6 centimeters or 7 centimeters.

[0064] In some embodiments, a connecting seat 15 is provided on the rear side of the base 1, and the second end of the limiting rod 5 is rotatably mounted on the connecting seat 15 via a rotating frame 51. Specifically, the connecting seat 15 is mounted on the rear side of the first frame 11 of the base 1 via a connecting frame 16, the connecting frame 16 extending rearward and upward from the first frame 11, and the connecting seat 15 is mounted on the top of the connecting frame 16.

[0065] In the above embodiment, the rotating frame 51 includes: a first rotating shaft end and a second rotating shaft end connected by a rotating frame body 511. The first rotating shaft end is used to connect to the second end of the limiting rod 5 to form a third rotating point C. The second rotating shaft end is used to connect to the connecting seat 15 to form a fourth rotating point D. A limiting member 52 is provided between the rotating frame body 511 and the connecting seat 15. The connecting frame 16, the rotating frame 51, the limiting rod 5, the swing arm 3, and the power arm 2 have rotating points A to D. The four-bar linkage principle is used to ensure that the movement trajectory of the handle 4 meets the arm flexion and extension action. The resistance structure is used to provide exercise load stimulation and contraction of the triceps brachii. The rotating frame body 511 is a connecting plate connecting the two sides of the first rotating shaft end and the two sides of the second rotating shaft end. The limiting member 52 is a limiting bolt that penetrates the connecting seat 15 and is inserted into the rotating frame body 511. The connecting seat 15 and the connecting plate are provided with corresponding limiting holes.

[0066] Based on the above structure, the triceps trainer sits on the seat 6 and holds the handle bar 4 with both hands. When the trainee pushes the handle bar 4, the swing arm 3 moves upward accordingly. The limit bar restricts the forward and backward swing amplitude of the swing arm 3. During the push, the resistance structure (such as counterweights or counterweight plates) will provide appropriate resistance, so that the trainee's triceps brachii will be fully stimulated and contracted.

[0067] In this embodiment, at least one limiting hole is provided. When there is only one limiting hole, as shown in the figure, when the swing arm 3 swings forward and backward, the second shaft end of the rotating frame 51 is rotatably fixed on the connecting seat 15. The limiting member 52 limits and fixes the rotating frame 511 on the connecting seat 15, thereby restricting the second end of the limiting rod 5 from moving with the swing arm 3, and correspondingly limiting the swing amplitude of the swing arm 3. The position of the limiting hole can also be set to multiple holes according to actual needs. The swing amplitude of the swing arm 3 is set according to the movement trajectory to avoid the handle bar 4 moving too far forward and contacting the trainee's head when it moves with the swing amplitude of the swing arm 3 during the movement, or moving too far backward and making it impossible for the trainee to grasp the handle bar 4 when performing arm flexion and extension movements.

[0068] In another embodiment, such as Figures 4-5 As shown, for ease of gripping by trainees, the handle 4 is configured as a curved handle with two straight sections 41 at both ends. Two first bends are mirror-imaged between the two straight sections, including a first straight section 42 bending in a first direction E, a second straight section F bending in a second direction, and a third straight section bending in a third direction G, which are connected sequentially. Referring to the figure, one side of the straight section 41 extends away from the end of the handle 4 and bends in the first direction E to form the first straight section 42, and then bends in the second direction F to form the second straight section 43. A wide grip position is provided at the two second straight sections 43.

[0069] The second straight rod section 43 extends in a third direction G to form a third straight rod section 44, constituting a V-shaped first bending part, and the straight rod section 41 on the other side extends in the same way to form another first bending part, which will not be described here; the third straight rod sections 44 of the two straight rod sections 41 are connected through a fourth straight rod section, which is coaxially arranged with the straight rod section 41, constituting a U-shaped second bending part, and a narrow grip position is provided at the two third straight rod sections 44, which has a stronger stimulating effect on the triceps brachii. The first direction E intersects the second direction F, and the third direction G intersects the second direction F.

[0070] Based on the design of the curved rod, the wrist can be held at a natural angle, better protecting the wrist joint and reducing the risk of excessive internal rotation of the wrist, providing a more comfortable holding experience; the grip distance and angle adjustment range of the conventional trainer is limited and cannot meet the needs of different trainers, while the handle rod 4 of the present application can support various changes in grip distance and angle, and the trainer with multiple grip distance and angle adjustments can effectively stimulate different muscle groups, providing more comprehensive training effects and more flexibility for the trainer; the trainer with the handle limiting connecting rod mechanism can more comprehensively stimulate all parts of the triceps brachii.

[0071] Reference Figures 2-3 As shown, the seat 6 is erected on the base 1 through a stand, and a headrest 7 is arranged on the seat 6. The headrest 7 is arranged on the back cushion of the seat 6, effectively supporting the head, conforming to the ergonomic principle, better fitting the natural shape of the human body, providing more comprehensive support and not causing discomfort to the trainer, and also limiting the excessive backward inclination of the head of the trainer, improving the safety of the training.

[0072] In order to adapt to the height of different trainers, the seat cushion of the seat 6 is connected to the stand in a height-adjustable manner. Specifically, the bottom of the seat cushion is connected to the stand through a wedge-shaped connecting plate 61, and can be fixed through a locking structure during sliding.

[0073] For example but not limited to, the locking structure is provided as a clamping groove structure. The front surface of the stand is provided with a limiting groove 62, a adjusting handle 63 is rotatably arranged between the wedge-shaped connecting plates 61, a spring is installed on the rotating shaft of the adjusting handle 63, a limiting part is fixedly arranged on the adjusting handle 63, and the adjusting handle 63 and the limiting part are linked.

[0074] When the adjusting handle 63 is lifted, the limiting part is out of the limiting groove 62, and the spring is compressed. At this time, the seat cushion can be adjusted in height flexibly; after the adjusting handle 63 is released, the elastic force of the spring pushes the adjusting handle 63 back to the original position, and at this time the limiting part is clamped into the limiting groove 62, preventing the seat cushion from sliding down.

[0075] In another embodiment, the seat cushion bottom is connected with a first end of a first gas spring 64, and a second end of the first gas spring 64 is fixedly connected to the stand bottom to assist in height adjustment of the seat cushion.

[0076] In order to improve the training comfort, a pedal frame 8 is further rotatably arranged on the base 1. The pedal frame 8 extends to one side of the seat 6 at a first end and is fixedly connected with a foot pedal 81, and a second end is fixedly arranged on a rotating support 82 which is rotatably connected to the base 1.

[0077] As shown in the drawings, the rotating support 82 includes a U-shaped frame body formed by a rotating cross frame 821 and two adapter frames 822, the rotating cross frame 821 is rotatably connected to the base 1, and the two adapter frames 822 are fixedly arranged at both ends of the rotating cross frame 821 and extend to one end of the power arm 2 close to the seat 6, wherein the top of the two adapter frames 822 directly or indirectly abuts against the power arm 2, when the pedal frame 8 drives the rotating support 82 to rotate, the adapter frame 822 moves upward and exerts an upward pushing force on the power arm 2 to make the swing arm 3 move upward.

[0078] In another embodiment, the top of the two adapter frames 822 is connected to a lifting part 823 through a reversing mechanism 84, the lifting part 823 abuts against the power arm 2, when the pedal frame 8 drives the rotating support 82 to rotate, the adapter frame 822 moves upward to drive the lifting part 823 to exert an upward force on the power arm 2.

[0079] Wherein, referring to Figure 6 The reversing mechanism is arranged to include a first transmission end 841, a second transmission end 842 and a third transmission end 843 which are fixedly connected in a triangular distribution, the first transmission end 841 is connected to the top of the adapter frame 822 through a connecting rod 844, one end of the connecting rod 844 is connected to the top of the adapter frame 822 through a rotating shaft, and the other end is connected to the first transmission end 841, the second transmission end 842 is rotatably arranged on the base 1, specifically on the inner side wall of the third frame body 13 of the base 1, and the third transmission end 843 is fixedly connected to the lifting part 823, the reversing mechanism rotates as a whole around its rotating point, thereby linking the first transmission end 841 and the third transmission end 843.

[0080] When the pedal frame 8 is stepped, the rotating support 82 rotates around the rotating point between the rotating cross frame 821 and the base 1, so that the top of the adapter frame 822 is displaced, the connecting rod 844 transmits the displacement of the adapter frame 822 to the first transmission end 841, the second transmission end 842 provides a stable support and rotating axis for the reversing mechanism, the reversing mechanism rotates based on the axis, thereby the first transmission end 841 converts the displacement into the displacement of the third transmission end 843, and the first transmission end 841, the second transmission end 842 and the third transmission end 843 cooperate together to realize the transmission and conversion of force, and the change of movement direction.

[0081] In the above embodiment, the rotating support 82 is connected with a first end of a second gas spring 83, and the second end of the second gas spring 83 is fixedly connected to the seat 6.

[0082] Based on the above structure, when the footrest 81 bears pressure, the second gas spring 83 contracts, and when the pressure on the footrest 81 is removed, the second gas spring 83 expands, and the second gas spring 83 expands to apply a downward force to the second end of the pedal support 8, so that the footrest 81 returns to and remains in the original position, and the direction of expansion of the second gas spring 83 is opposite to the moving direction of the footrest when the footrest is stepped on, and the original position refers to the static position of the footrest 81 when the footrest is not stepped on.

[0083] In addition, the second support body 12 and the force arm 2 are further provided with a hanging rod 9 for mounting an elastic member to provide elastic resistance.

[0084] When the triceps trainer is used for training, the height of the seat 6 can be adjusted to meet the needs of different heights, the arm is bent to hold the handle rod 4, the elbow is close to the two sides of the head, the handle is pushed upward to lift, the triceps brachii is more effectively exercised, and the strength and endurance of the upper arm are improved.

[0085] It should be finally pointed out that: the various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts of each embodiment can be referred to.

[0086] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the present application; although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the specific embodiments of the present application can be modified or some technical features can be replaced by equivalent ones; without departing from the spirit of the technical solutions of the present application, all of them should be covered in the technical solution range of the present application claimed.
