Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, specifically fitness training institutions and fitness equipment. Background Technology

[0002] In the field of fitness equipment, training machines that achieve exercise load through mechanical structures are the core equipment type for improving training effectiveness. Among them, fitness equipment that achieves exercise load through mechanical swinging structures is a key focus of industry research and development due to its adaptability to various limb training scenarios and its balance of training safety and targeted application. To meet the need for convenient component connection during training, existing related institutions have developed steel cable retrieval devices using a turntable and ratchet structure. The core design concept is as follows: during training, the steel cable is released and connected to other external training components to achieve force transmission and training function of mechanical swinging load; after training or when the steel cable is no longer needed, it can be retrieved back to the machine by rotating the turntable. This effectively avoids the problems of cumbersome disassembly and inconvenient cable storage in traditional detachable steel cable connection methods, thus improving the ease of use of the equipment to a certain extent.

[0003] However, the existing steel cable retrieval structure used in fitness equipment that achieves exercise load through mechanical swinging still has certain drawbacks in practical applications, specifically as follows: First, the structure is relatively complex. The device needs to be assembled from multiple machined parts such as a turntable, ratchet, steel cable, and fixed connectors. This not only increases the assembly difficulty of the equipment but also leads to higher manufacturing costs due to the large number of parts, which is not conducive to the large-scale promotion of the product. Second, the force distribution is not ideal. The steel cable fixed at one end of the machine and the wheel that works with it must continuously bear the tension generated by the mechanical swinging load and the tension during the cable retrieval during training. Being under high load for a long time can easily lead to problems such as loosening of the fixed end of the steel cable and wear and deformation of the wheel, affecting the service life and safety of the equipment. Third, the force transmission efficiency is limited. Due to the limitations of the overall structural layout and installation space of the equipment, the diameter of the wheel cannot be designed to be too large. According to the principle of mechanical transmission, this means that the actual effective load force output by the mechanical swinging structure is only about half of the external tension, which significantly reduces training efficiency and makes it difficult to meet users' needs for high-intensity and high-efficiency training.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Please see Figure 1 and Figure 2 This application provides the following technical solutions: The fitness training device includes a fixed frame 1, a swing frame 2, and a linkage structure 3. The fixed frame 1 serves as the support structure of the device, its structure only needing to provide stable support force. A first rotatable connection position is reserved on the fixed frame 1. The frame of the swing frame 2 is rotatably connected to the fixed frame 1 via the first rotatable connection position. The swing frame 2 is equipped with a force-applying structure that facilitates the application of force by the human body. Furthermore, the swing frame 2 is equipped with a counterweight structure 23, through which counterweights, such as barbell plates, can be directly hung. The linkage structure 3 is linked with the swing frame 2.

[0024] Fixed frame 1 serves as the fixed part of the training mechanism, while swing frame 2 is the movable part. During training, the swing frame 2 performs a swinging motion by targeting the body part to be trained, thus providing force input to the training mechanism during exercise. The body parts to be trained include common leg and arm movements, such as kicking and calf bends. Arm movements are similar. The application of this type of swinging structure in fitness mechanisms is existing technology and will not be listed here. The key improvement of this solution lies in the structural form of the linkage structure 3.

[0025] The linkage structure 3 includes a gas spring 31, a fixed pulley assembly 32, a movable pulley assembly 33, and a cable. The gas spring 31 can be a pre-made gas spring, comprising a pressure cylinder, piston rod, piston, sealing guide sleeve, and inert gas filling material. The gas spring itself is existing technology, and its specific structure will not be described in detail here. In this design, the piston rod of the gas spring 31 is positioned upwards. The cylinder end of the gas spring 31 is rotatably connected to the fixed frame 1. The end of its piston rod, i.e., the movable end of the gas spring 31, is linked with the movable pulley in the movable pulley assembly 33, causing the movable pulley to rise and fall as the gas spring 31 rises and falls. The fixed pulley in the fixed pulley assembly 32 serves as a guide structure for the cable, and is rotatably connected to the fixed frame 1. One end of the cable is connected to the swing frame 2, the middle of the cable wraps around the fixed and movable pulleys, and the other end of the cable can be linked to an external counterweight mechanism. A steel cable is commonly used.

[0026] By combining fixed pulley assembly 32 and movable pulley assembly 33 with cables, the linkage between the swing frame 2 and the external counterweight is achieved. The external counterweight can be a common counterweight assembly load structure with cable-connected lifting mechanism, and the corresponding counterweight frame has a vertically movable counterweight assembly inside. By pulling the cables, the counterweight assembly rises and falls inside the counterweight frame, thus serving as the moving load. This type of external counterweight is not the focus of this solution; it is an application of existing technology and will not be elaborated upon further here.

[0027] In other words, this structure can be adapted to the linkage structure that involves structural swinging in fitness training and is combined with the aforementioned external counterweight. There is no technical barrier to combining it with existing equipment. It can be easily applied to various existing fitness equipment structures and is also suitable for simple modification and adaptation of existing fitness equipment.

[0028] This design incorporates a gas spring 31 and a combination of movable and fixed pulleys as the linkage structure of the swing frame 2. This allows for training in different ways. When the cable of the linkage structure 3 is not connected to the external counterweight, only the barbell plates can be hung on the counterweight structure 23 of the swing frame 2. The cable automatically rebounds via the gas spring. Besides fulfilling the working stroke, the gas spring 31 also provides additional auxiliary force. When the cable is connected to the external counterweight and external force is applied, the movable end of the gas spring 31 is compressed at the bottom, and the pulled-out cable fulfills the working stroke.

[0029] On the basis of the above embodiment, the fixing frame 1 includes a fixed base frame 11 and a fixed vertical frame 12. The fixed base frame 11 in the present solution adopts a "匚"-shaped frame body as a whole, which is placed flat on the ground, and two rollers are arranged on the opening side of the fixed base frame 11. When the fixed base frame 11 is placed flat, the rollers do not contact the ground; when the fixed base frame 11 is tilted, the rollers contact the ground, which facilitates dragging.

[0030] The fixed vertical frame 12 adopts an inclined frame structure. The lower end of the frame body of the fixed vertical frame 12 is connected to the closed end of the fixed base frame 11, and the connection form is that the bottom end of the fixed vertical frame 12 is provided with a sleeve, which is sleeved on the fixed base frame 11 through the sleeve. A plurality of positioning holes are opened at the closed end of the fixed base frame 11, and the sleeve of the fixed vertical frame 12 and the positioning holes are fixed by positioning pins. The first rotation connection position is arranged at the top of the fixed vertical frame 12.

[0031] On the basis of the above embodiment, the swing frame 2 includes a first swing rod 24 and a second swing rod 25. The first swing rod 24 and the second swing rod 25 are arranged at an obtuse angle and are fixedly connected to each other. The upper end of the rod body of the first swing rod 24 is rotatably connected to the fixing frame 1 through the first rotation connection position; the first force applying structure 21 is arranged at the middle-lower part of the first swing rod 24; the bottom end of the first swing rod 24 is provided with a connection structure that can be connected with a cable. One end of the second swing rod 25 is fixedly connected to the end of the first swing rod 24 close to the first rotation connection position, and the other end extends in a direction away from the first swing rod 24; the second force applying structure 22 is arranged at the end of the second swing rod 25 away from the first swing rod 24.

[0032] With this structure, the first force applying structure 21 and the second force applying structure 22 are respectively arranged on the first swing rod 24 and the second swing rod 25. Through the use of the two force applying structures, different fitness movements can be completed. Therefore, the first force applying structure 21 and the second force applying structure 22 can be set in various forms according to requirements.

[0033] Taking leg movement as an example, both the first force applying structure 21 and the second force applying structure 22 adopt symmetrically arranged elastic roller structures. This mechanism is combined with a corresponding human body support structure, such as a seat or recliner type structure, to Figure 1 take the direction shown as an example: the user can exercise in a lying posture facing upward, or in a sitting posture facing right, then can hook the first force applying structure 21 to perform leg kicking exercises. When the user exercises in a prone posture facing downward, the leg or ankle position can be used to hook the second force applying structure 22 to perform leg hooking exercises.

[0034] This structural form is only one application mode of the present solution, but is not limited to this application form.

[0035] Based on the above implementation plan, as mentioned above regarding the counterweight form of this institution, a counterweight structure 23 is also provided on the swing frame 2. By directly connecting the counterweight through the counterweight structure 23, fitness training can be carried out without using external counterweights via cables.

[0036] A counterweight connecting frame 26 is provided between the first swing rod 24 and the second swing rod 25. The lower end of the counterweight connecting frame 26 extends toward the lower end of the first swing rod 24 away from the fixed stand 12. The counterweight structure 23 directly adopts a hanging rod that can hang barbell plates. One end of the rod is fixedly connected to the counterweight connecting frame 26, and the other end of the rod is inclined upward away from the fixed base 11.

[0037] Based on the above implementation scheme, a groove is provided on the body of the first swing rod 24, the first force-applying structure 21 and the groove of the first swing rod 24 are slidably connected, and a locking bolt is provided at the connection.

[0038] The second swing rod 25 adopts a telescopic rod structure in which the inner rod is sleeved onto the outer rod. The inner rod and the outer rod are slidably connected. Several positioning holes are distributed on the inner rod, and spring pins are provided on the outer rod. The overall length of the second swing rod 25 is locked by the spring pins.

[0039] The structure of this solution allows for adjustable positions of the first force-applying structure 21 and the second force-applying structure 22 to accommodate the needs of users with different body shapes.

[0040] Based on the above implementation plan, see Figures 3 to 6 The connection between the bottom end of the first swing rod 24 and the cable can be achieved using various existing structures, as long as it can be fixed to the end of the cable. The fixed pulley assembly 32 includes a first fixed pulley 321 and a second fixed pulley 322. The first fixed pulley 321 is rotatably mounted on the bottom of the fixed frame 12 via its corresponding pulley seat, while the second fixed pulley 322 is rotatably mounted on the fixed base frame 11 via its pulley seat, and the second fixed pulley 322 is located below the first fixed pulley 321.

[0041] The movable pulley assembly 33 also includes a movable pulley frame 331. The movable pulley is rotatably connected to the movable end of the gas spring 31 (i.e., the upper end of the gas spring 31) via the movable pulley frame 331. The lower end of the gas spring 31 is rotatably connected to the bottom of the fixed support frame 12. One side of the movable pulley frame 331 is rotatably connected to the upper end of the gas spring 31, and the movable pulley is rotatably mounted on the side of the movable pulley frame 331 away from the gas spring 31. Two movable pulleys are arranged coaxially side by side, and two first fixed pulleys 321 are also arranged side by side.

[0042] After one end of the cable is connected to the bottom of the first swing rod 24, it first passes over the second fixed pulley 322 from bottom to top. Then the cable goes up and passes over one of the movable pulleys from above, turns downward, passes over one of the first fixed pulleys 321 below, turns upward again and passes over another movable pulley. After that, the cable goes down and passes over the last first fixed pulley 321, and a connector is reserved at the end of the cable to facilitate its connection with the external counterweight structure.

[0043] Based on the above implementation scheme, the linkage structure 3 also includes two parallel guide rods 34, which are fixedly connected to the fixed support frame 12; the axial direction of the guide rods 34 is parallel to the lifting direction of the movable pulley frame 331 in the movable pulley assembly 33. Two sleeve structures are provided on the movable pulley frame 331, and linear bearings are installed inside the sleeves. The movable pulley frame 331 is slidably connected to the guide rods 34 through the sleeve structures.

[0044] The training institution under this program has the following main characteristics: 1. Utilize the structural characteristics of the gas spring 31 to achieve automatic cable retrieval.

[0045] Second, the recovery process is stable and smooth by using linear bearings and double guide rods 34.

[0046] 3. When an external counterweight is connected and external force is used, the gas spring 31 is compressed at the bottom, and the pulled-out cable is sufficient to meet the working stroke.

[0047] IV. When no external counterweight is connected and only barbell plates are used as exercise counterweight, the cable automatically rebounds through the gas spring 31. In addition to meeting the working stroke, the gas spring 31 can also play a role in increasing auxiliary force.
