Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a plate-type triceps trainer. Background Technology

[0002] With the continuous improvement of socioeconomic levels, people's health awareness has significantly increased. Against the backdrop of national fitness initiatives, fitness activities have expanded from the realm of professional sports to everyday life. Currently, gyms, as the mainstream fitness venue, have seen their equipment functionality and specialized features become a focus of user attention.

[0003] Currently, commercial triceps training equipment mainly falls into two technical categories: plate-type weight machines and free weight training equipment. Plate-type machines require the integration of multiple weight plates and transmission structures, resulting in a generally large footprint per machine and significantly increasing the space operation costs of commercial gyms. While free weight equipment such as dumbbells and barbells offer flexibility, their open movement trajectory makes it difficult to fix the movements, leading to insufficient activation of the target muscle groups. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model proposes a plate-type triceps trainer. The plate-type counterweight method of this triceps trainer can effectively reduce the manufacturing cost of the equipment, and the four-bar linkage structure as the transmission component can effectively reduce the equipment's footprint and improve the space utilization of the gym.

[0005] A plate-type triceps trainer includes a main support frame, on which a seat assembly and a backrest assembly are fixed. A movement arm is connected to the top of the main support frame via a first rotating shaft joint. The top of the movement arm is a gripper, and the end is connected to a weight arm via a second rotating shaft joint. The weight arm is connected to the main support frame near its middle position via a movable link. When the movement arm is rotated, the weight arm rotates around a fixed trajectory under the combined constraint of the movement arm and the movable link. A plate hanger is fixed to the end of the weight arm.

[0006] As a preferred embodiment of the above technical solution, the motion arm has a three-section structure, including an arc-shaped clearance rod section connected sequentially at the upper end of the first rotation axis joint, a handle, and a transition rod section connecting the first rotation axis joint and the second rotation joint. The transition rod section, the gravity arm, the movable connecting rod, and the main support frame form a four-bar linkage structure.

[0007] As a preferred embodiment of the above technical solution, the means is inserted into the arc-shaped avoidance rod segment and the insertion depth can be adjusted.

[0008] As a preferred embodiment of the above technical solution, the seat cushion assembly is inserted into a positioning rod fixed to the main support frame and the insertion depth can be adjusted.

[0009] As a preferred embodiment of the above technical solution, a buffer block is installed on the main support frame directly opposite the end of the gravity arm.

[0010] As a preferred embodiment of the above technical solution, the main support frame is symmetrically provided with two sets of bell hangers, one in the front and one in the rear.

[0011] As a preferred embodiment of the above technical solution, anti-slip pads are fixed on the support feet of the main support frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Using a hanging counterweight method can effectively reduce equipment manufacturing costs.

[0014] 2. The use of a four-bar linkage as the transmission component can effectively reduce the equipment's footprint and improve the space utilization of the gym.

[0015] 3. Based on ergonomic principles and sports biomechanics, the fixed movement trajectory ensures precise training of the corresponding muscle groups during exercise. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] like Figure 1 , Figure 2The aforementioned plate-type triceps trainer includes a main support frame 1, on which a seat assembly 2 and a backrest assembly 3 are fixed. A movement arm 5 is connected to the top of the main support frame 1 via a rotating shaft joint 4. The top of the movement arm 5 is a gripper, and its end is connected to a gravity arm 7 via a rotating shaft joint 6. The gravity arm 7 is connected to the main support frame 1 near its center via a movable link 8. When the movement arm 5 is rotated, the gravity arm 7 rotates around a fixed trajectory under the combined constraint of the movement arm 5 and the movable link 8. A weight plate hanging rod 9 is fixed to the end of the gravity arm 7. Both the seat assembly 2 and the backrest assembly 3 are assembled from a base and an elastic pad. The weight plate hanging rod 9 is also equipped with a pin to prevent the weight plates from falling off.

[0021] In this embodiment, the motion arm 5 has a three-section structure, including an arc-shaped clearance rod section 501 and a handle 502 connected sequentially at the upper end of the first rotational joint 4, and a transition rod section 503 connecting the first rotational joint 4 and the second rotational joint 6. The transition rod section 503, the gravity arm 7, the movable connecting rod 8 and the main support frame 1 form a four-bar linkage structure.

[0022] In this embodiment, the means 502 is inserted into the arc-shaped avoidance rod segment 501 and the insertion depth can be adjusted.

[0023] In this embodiment, the seat cushion assembly 2 is inserted into a positioning rod 10 fixed to the main support frame 1 and the insertion depth can be adjusted.

[0024] In this embodiment, a buffer block 11 is installed on the main support frame 1 directly opposite the end of the gravity arm 7.

[0025] In this embodiment, the main support frame 1 is symmetrically provided with two sets of bell hanger rods 12, one in front and one in back.

[0026] In this embodiment, anti-slip pads 13 are fixed on the support feet of the main support frame 1.

[0027] When using this plate-type triceps trainer, first adjust your posture using the seat assembly 2 and backrest assembly 3, then grip the handle 502 to drive the movement arm 5 along a preset trajectory. This movement is achieved through a four-bar linkage system that links the gravity arm 7, ensuring the target muscle group remains in its optimal range of motion.

[0028] This product innovatively adopts a modular four-bar linkage mechanical system, reducing the planar area compared to traditional plate-type structures. Through the angle variation of the gravity arm 7, in conjunction with the four-bar linkage mechanical system, dynamic balance of the moment of inertia is achieved during movement, meeting biomechanical standards. The angle locking of the movement arm 5 allows for precise control of the shoulder joint's movement within its functional range of motion, resulting in better triceps training. Compared to plate-type weight machines and free weight training equipment, this solution achieves technological breakthroughs in both space efficiency and movement standardization.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
