[0001] This utility model relates to the field of training equipment technology, and in particular to a portable tendon training device for the elderly. Background Technology

[0002] Muscle training equipment for seniors is fitness equipment specifically designed to enhance muscle strength and improve joint flexibility in older adults. These devices are typically adjustable to accommodate different ages and health conditions, helping seniors engage in safe and effective strength training. Common equipment includes resistance bands, exercise chairs, and low-intensity strength training machines. Through regular training, these devices can improve balance, reduce the risk of falls, promote physical and mental health, and enhance independence in daily living.

[0003] A search revealed that Chinese patent CN220495516U discloses an upper limb training device for the elderly. The device includes an I-shaped lower base, a seat column at the rear of the lower base, a seat on the seat column, an inclined support column at the front of the lower base, an upper platform at the top of the inclined support column, a damping spring axially connected to the inclined support column at its lower end, a winder on the upper platform, a rotating wheel connected to and driving the winder, and a connecting rope connected between the winder and the upper part of the damping spring, driven by the rotating wheel for winding. This invention offers advantages such as simple structure and ease of use, possessing high practical and promotional value in the field of training equipment technology.

[0004] While the aforementioned patent is convenient to use, it cannot be carried around for travel and is inconvenient to consistently adhere to the planned schedule, resulting in reduced flexibility in the use of the device. Therefore, a portable tendon training device for the elderly is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable tendon training device for the elderly, aiming to improve the problems of existing technologies that cannot be carried around for travel and are inconvenient to consistently adhere to the training plan.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable tendon training device for the elderly includes a housing, an adjustment mechanism installed on one side of the housing, a connection mechanism provided on one side of both the housing and the adjustment mechanism, support mechanisms provided on both sides of the bottom of the housing, and a storage mechanism provided at the bottom of the housing.

[0008] The connecting mechanism includes two main shafts. Multiple springs are fixedly connected to the inner walls of both sides of the main shafts. A sliding plate is fixedly connected to the other end of each spring. A locking ball is fixedly connected to the other end of the sliding plate. Connecting rods are installed on both sides of the main shafts. Grooves are formed on all four sides of the outer side of each connecting rod. The outer side of the locking ball engages with the inner wall of the groove. A separation component is installed on one side of the connecting rod. A support trainer is fixedly connected to one side of the separation component.

[0009] With the above technical solution: when the connecting rod is inserted into the main shaft, the ball is squeezed and pushes the sliding plate to compress the second spring until the ball is aligned with the groove. Then the second spring rebounds and the ball is locked into the groove. During training, the force is evenly transmitted to the main shaft through the connecting rod. The multi-spring design ensures force balance. When separating, simply pull the connecting rod lightly and the ball will slide out of the groove along the inclined surface to disassemble.

[0010] As a further description of the above technical solution:

[0011] The adjustment mechanism includes a housing, one side of which is fixedly connected to one side of the housing. A sliding post is slidably connected to the top of the housing. Multiple slots are provided on the outside of the sliding post. A fixed box is fixedly connected to one side of the housing. A control rod is slidably connected to one side of the fixed box. A spring is sleeved on the outside of the control rod. A limiting block is fixedly connected to the outside of the control rod. The outside of the control rod engages with the inner wall of the slot.

[0012] The above technical solution works as follows: when the control lever is pressed down, the limiting block is disengaged from the slot of the sliding column, and the first spring is compressed to store energy. At this time, the sliding column can be freely slid to the desired height position. After the control lever is released, the first spring releases its elastic force and pushes the limiting block to automatically engage in the corresponding slot, thus completing the height locking. The multi-position slot design provides precise height adjustment, and the self-resetting characteristic of the first spring ensures reliable locking after each adjustment.

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected to the inner wall of one side of the fixed box, and the other end of the spring is fixedly connected to one side of the limiting block.

[0015] The above technical solution involves pressing the control lever to compress the spring, and then releasing the spring to reset it, causing the limiting block to engage in the slot and lock the height.

[0016] As a further description of the above technical solution:

[0017] The support mechanism includes two movable plates. Cavities are provided on both sides of the bottom of the housing. The outer side of the movable plate is slidably connected to the inner wall of the cavity. Support plates are rotatably connected to both sides of the bottom of the movable plate. Two sealing plugs are installed on one side of the housing. One side of the sealing plug engages with one side of the cavity.

[0018] The above technical solution allows for the convenient switching between quick storage and stable support: pulling the movable plate unfolds the support plate to form a stable base, and after training, it is folded back into the cavity and fixed with a sealing plug.

[0019] As a further description of the above technical solution:

[0020] The storage mechanism includes a closed cover, and a placement groove is provided at the bottom of the housing. The outer side of the closed cover is slidably connected to the inner wall of the placement groove.

[0021] The above technical solution allows for the sliding opening of the closed cover to access the components inside the slot. When closed, it prevents dust and loss. The push-pull design allows for one-handed operation, balancing convenience and storage safety.

[0022] As a further description of the above technical solution:

[0023] The separation assembly includes an extension rod, one side of which is fixedly connected to one side of the connecting rod. A threaded groove is provided on one side of the extension rod, and a threaded post is threadedly connected to the inner wall of the threaded groove. One side of the threaded post is fixedly connected to one side of the support trainer.

[0024] The above technical solution allows the screw-on support trainer to complete assembly by screwing the threaded column into the threaded groove of the extension rod, and disassembly by rotating in the opposite direction. The threaded connection ensures that the trainer is stable and does not loosen during training, and is easy to assemble and disassemble.

[0025] As a further description of the above technical solution:

[0026] The sliding plate is externally slidably connected to the inner wall of the main shaft, and the limiting block is externally slidably connected to the inner wall of the fixed box;

[0027] Through the above technical solution: the sliding plate slides smoothly along the inner wall of the main shaft to realize the extension and retraction of the ball, the limiting block moves precisely in the fixed box to complete the locking, and the double sliding structure ensures smooth adjustment without jamming.

[0028] As a further description of the above technical solution:

[0029] One of the main shafts is externally rotatably connected to the inner wall of the sliding column, and the other main shaft is externally rotatably connected to the inner wall of the housing;

[0030] The above technical solution achieves height adjustment linkage through the rotational cooperation of the upper main shaft and the sliding column, while the lower main shaft is fixedly connected to the housing to ensure the stability of the basic structure.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, height adjustment is achieved through the nesting of the shell and the sliding column. The engagement of the sliding column's slot and the limiting block ensures stable positioning. A spring inside the main shaft pushes the sliding plate, causing the ball to elastically engage with the groove of the connecting rod, enabling quick assembly and disassembly. The end of the connecting rod is fixed by screwing a threaded groove into the threaded column of the support trainer. The bottom moving plate slides with the cavity, and the support plate can be rotated and folded. The sealing plug is used to fix the storage position. The disassembled components can be stored in the placement slot and protected by a sliding closing cover. The precise fit of each structure ensures stability in use and enables quick assembly and disassembly through nesting, snap-fit, and threaded connections, minimizing the overall size and making it easy to carry and store.

[0033] 2. In this utility model, stepless height adjustment can be achieved through simple pull and press control rod operation, allowing the elderly to easily adjust to the most comfortable exercise position. The spring-assisted slot locking mechanism ensures automatic and stable fixation after adjustment, effectively preventing accidental slippage during training. Multiple height settings meet different training needs and improve exercise effect. Attached Figure Description

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Reference Figures 1 to 3 This utility model provides an embodiment of a portable tendon training device for the elderly, including a housing 1, which adopts a lightweight design to facilitate carrying and moving for the elderly. An adjustment mechanism 2 is installed on one side of the housing 1, which can flexibly adjust the height of the device according to usage needs to make training more comfortable. Both the housing 1 and the adjustment mechanism 2 are provided with a connecting mechanism 3 on one side to realize quick disassembly and assembly, which is convenient for storage and assembly. Both sides of the bottom of the housing 1 are provided with support mechanisms 4 to provide stable support and can be folded for storage to save space. The bottom of the housing 1 is provided with a storage mechanism 5 for safely storing disassembled components to avoid loss or damage.

[0044] Specifically, the height can be flexibly adjusted by the adjustment mechanism 2 to adapt to different training needs and ensure comfort. The connection mechanism 3 enables quick disassembly and assembly, making it easy to store and assemble. The support mechanism 4 provides stable support when unfolded and saves space when folded. The storage mechanism 5 is used to store disassembled components to prevent loss or damage. When in use, the elderly can use the equipment to perform tendon stretching or strength training. The lightweight shell 1 is easy to carry. The overall design takes into account both safety and convenience, meeting the daily exercise needs of the elderly.

[0045] The connecting mechanism 3 includes two main shafts 31, which serve as the core connecting components to ensure structural stability. Multiple springs 32 are fixedly connected to the inner walls of both sides of the main shafts 31 to provide stable elastic locking force and ensure reliable connection. A sliding plate 33 is fixedly connected to the other end of the springs 32, which drives the locking ball 34 to move, achieving quick locking and separation. The locking ball 34 is fixedly connected to the other end of the sliding plate 33 and cooperates with the groove 36 to ensure a stable connection and easy operation. Connecting rods 35 are installed on both sides of the main shafts 31 to connect the trainer and transmit the force during training. Grooves 36 are opened on all four sides of the outer side of the connecting rods 35 to cooperate with the locking ball 34 for precise positioning and fixation. The outer side of the locking ball 34 engages with the inner wall of the groove 36, providing clear tactile feedback when engaged, making it easy to confirm the connection status. A separation component 37 is installed on one side of the connecting rods 35 to achieve quick assembly and disassembly of the support trainer 38. The support trainer 38 is fixedly connected to one side of the separation component 37 for hand and leg tendon training to improve muscle strength in the elderly.

[0046] Specifically, the connecting mechanism 3 uses springs 32 on both sides of the main shaft 31 to push the sliding plate 33, so that the locking ball 34 is precisely engaged with the groove 36 on the connecting rod 35, achieving quick locking and ensuring structural stability during training. When disassembly is required, the separation component 37 can compress the spring 32, causing the locking ball 34 to disengage from the groove 36, achieving one-click separation. The connecting rod 35 transmits training force to the support trainer 38 for hand or leg tendon exercises. The elastic engagement design provides clear tactile feedback, making it easy for the elderly to operate. The overall structure balances stability and convenience, meeting the needs of safe and efficient training.

[0047] refer to Figure 4 and Figure 5The adjustment mechanism 2 includes a housing 21, which guides the sliding column 22 to ensure smooth height adjustment. One side of the housing 21 is fixedly connected to one side of the housing 1 to maintain structural integrity and improve stability. The top of the housing 21 is slidably connected to the sliding column 22, allowing the device height to be adjusted up and down to meet different training needs. The sliding column 22 has multiple slots 23 on its exterior, providing multiple fixing points to meet different height requirements. One side of the housing 21 is fixedly connected to a fixing box 24, which houses the control lever 25 and spring 26, protecting the internal mechanism. One side of the fixing box 24 is slidably connected to the control lever 25 for manual unlocking and locking of the height adjustment. The control lever 25 is fitted with spring 26 on its exterior, providing an automatic reset function to ensure reliable locking. A limiting block 27 is fixedly connected to the exterior of the control lever 25, which is connected to the slots 23. In conjunction with the fixed height of the sliding column 22, the outer side of the control rod 25 engages with the inner wall of the slot 23, locking the sliding column 22 to prevent accidental movement and ensure training safety. One end of the spring 26 is fixedly connected to the inner wall of the fixed box 24 to fix the spring position and ensure stable elastic force. The other end of the spring 26 is fixedly connected to the side of the limiting block 27 to drive the limiting block 27 to reset and achieve automatic locking. The outer side of the sliding plate 33 is slidably connected to the inner wall of the main shaft 31 to ensure smooth operation of the engaging mechanism. The outer side of the limiting block 27 is slidably connected to the inner wall of the fixed box 24 to ensure locking accuracy and avoid deviation. The outer side of one main shaft 31 is rotatably connected to the inner wall of the sliding column 22 to achieve height adjustment linkage. The outer side of the other main shaft 31 is rotatably connected to the inner wall of the housing 1 to maintain the basic connection and ensure structural stability.

[0048] Specifically, when the equipment height needs to be adjusted, the user pulls the control lever 25 outward, causing the limiting block 27 to disengage from the slot 23 on the sliding column 22. Simultaneously, the spring 26 is compressed, releasing the sliding column 22, which can then slide freely up and down along the housing 21 to accommodate different training needs. After adjusting to the appropriate position, the control lever 25 is released, and the elastic restoring force of the spring 26 pushes the limiting block 27 to automatically reset, causing it to re-engage in the corresponding height slot 23, achieving quick locking. The fixing box 24 provides support for the control lever 25 and the spring 26. Stable support ensures precise operation of the locking mechanism. The sliding engagement between the sliding column 22 and the housing 21 ensures smooth and stable height adjustment, while the multi-position slot 23 provides precise height positioning. When adjusting the height, the rotating main shaft 31 connected in the sliding column 22 will move in sync, keeping the connecting mechanism 3 in the optimal working position. The entire adjustment process can be operated with one hand. The automatic reset function of the spring 26 ensures reliable locking after each adjustment, which not only meets the convenience needs of elderly people but also ensures structural stability and safety during training.

[0049] refer to Figure 6The support mechanism 4 includes two movable plates 41, which serve as the base of the support structure and can be slidably adjusted in position. Cavities 43 are provided on both sides of the bottom of the housing 1 to provide storage space and facilitate folding of the support mechanism 4. The outer side of the movable plates 41 is slidably connected to the inner wall of the cavity 43 to realize the unfolding and storage of the support mechanism 4. Support plates 42 are rotatably connected on both sides of the bottom of the movable plates 41 to provide stable support when unfolded and save space when folded. Two sealing plugs 44 are installed on one side of the housing 1 to seal the cavity 43, prevent dust from entering and fix the support plate 42. One side of the sealing plug 44 is engaged with one side of the cavity 43 to ensure a stable storage state and prevent the support plate 42 from being accidentally unfolded. The storage mechanism 5 includes a sealing cover 51 to protect the stored components and prevent loss or damage. A placement groove 52 is provided at the bottom of the housing 1 for storing the disassembled support trainer 38 and the separation component 37. The outer side of the sealing cover 51 is slidably connected to the inner wall of the placement groove 52 for quick opening and closing and easy access to the components.

[0050] Specifically, when the equipment is needed, first remove the sealing plug 44, pull out the two movable plates 41 from the cavity 43 and unfold them. The support plate 42 then rotates to a vertical position to form a stable support surface. After training, fold the support plate 42 back to its original position, push the movable plate 41 back into the cavity 43, and fix it with the sealing plug 44 to achieve compact storage. The storage mechanism 5 opens the placement slot 52 through the sliding closing cover 51, which can safely store the disassembled support trainer 38 and other components. After closing, it is dustproof and prevents loss. The overall design realizes the quick unfolding / folding function, which not only ensures the stability of training, but also makes it easy to carry and store.

[0051] refer to Figure 2 and Figure 4 The separation component 37 includes an extension rod 371, a connecting rod 35, and a support trainer 38 to transmit training force. One side of the extension rod 371 is fixedly connected to one side of the connecting rod 35 to ensure a stable connection and prevent loosening during training. One side of the extension rod 371 has a threaded groove 372 for threaded connection to achieve quick assembly and disassembly. The inner wall of the threaded groove 372 is threaded with a threaded post 373, which allows the support trainer 38 to be installed and disassembled by rotation. One side of the threaded post 373 is fixedly connected to one side of the support trainer 38 to ensure stable force on the trainer and prevent it from falling off.

[0052] Specifically, when the support trainer 38 needs to be installed, align the threaded post 373 with the threaded groove 372 of the extension rod 371, rotate the support trainer 38 to screw it in and fix it, achieving quick locking. To disassemble, simply rotate in the opposite direction to separate it. The extension rod 371 stably transmits the training force from the connecting rod 35 to the support trainer 38. The threaded connection structure ensures that it will not loosen or fall off during training. This design not only enables quick assembly and disassembly of the training components, making them easy to store and carry, but also ensures the structural strength and operational safety during tendon training, making it particularly suitable for the elderly.

[0053] Working principle: When the equipment is needed, the hands and legs are exercised respectively through two sets of support trainers 38. When the hand equipment needs to be adjusted, the control rod 25 is pulled. The control rod 25 will move the limiting block 27. At this time, the movement of the limiting block 27 will compress the spring 26, causing the spring 26 to deform and generate elastic potential energy. At this time, the control rod 25 will disengage from the inner wall of the slot 23. At this time, the sliding column 22 can be slid on the top of the shell 21 to adjust the height of the sliding column 22. By releasing the control rod 25, the spring 26 releases its elastic potential energy, and the control rod 25 returns to its original position and engages with the slot 23 to complete the fixation, thereby fixing the height of the sliding column 22 and realizing the adjustment.

[0054] When the equipment needs to be carried, the sliding column 22 is retracted into the housing 21, and the support trainer 38 is pulled outward. The pull of the support trainer 38 causes the connecting rod 35 to move, at which point the connecting rod 35 will retract from the inner wall of the main shaft 31. During this process, the retaining ball 34 will press against the inner wall of the groove 36, causing the retaining ball 34 to push the sliding plate 33 to compress the spring 32, thus causing the retaining ball 34 to retract into the inner wall of the main shaft 31, allowing the connecting rod 35 to be easily pulled out. Finally... By rotating the support trainer 38, the threaded column 373 will rotate. At this time, the rotation of the threaded column 373 will be threaded into the inner wall of the threaded groove 372. Through the continuous rotation of the threaded column 373, the threaded column 373 will be disengaged from the inner wall of the threaded groove 372, thereby separating the separation component 37 from the support trainer 38. Finally, the disassembled support trainer 38 and separation component 37 are placed in the placement slot 52, and the placement slot 52 is closed by the sealing cover 51.

[0055] Finally, rotate the support plate 42 so that the two support plates 42 are parallel. Then slide the moving plate 41 on the inner wall of the cavity 43, and insert the support plate 42 into the inner wall of the cavity 43. Finally, remove the sealing plug 44 and insert the sealing plug 44 into the bottom of the cavity 43 to complete the storage and make the device easy to carry.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
