Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of rehabilitation equipment, and particularly relates to a standing frame. BACKGROUND

[0002] In recent years, with the change of modern social lifestyle, insufficient exercise and long-term improper standing or walking have led to more and more people suffering from foot and ankle dysfunction, such as foot eversion, foot drop and ankle deformation. These diseases not only affect the quality of life of patients, but also may further lead to loss of motor function and chain reaction in other parts of the body. Therefore, it has become a technical problem to be solved to develop a rehabilitation device that can effectively perform foot rehabilitation exercise and correct the above problems.

[0003] At present, although there are various rehabilitation devices on the market that can be used for foot rehabilitation training, most of the existing devices have complex structures, are inconvenient to adjust or are not comfortable to use. For example, some traditional rehabilitation devices need to be manually adjusted in angle and are complex to operate, which is not suitable for long-term use. While some other devices have angle adjustment function, but cannot accurately control the angle change or cannot provide sufficient flexibility and comfort, which is difficult to meet the needs of different patients. Therefore, how to design a standing frame that can accurately and conveniently adjust the elevation angle and provide appropriate rehabilitation training effect is an important problem in the current technology.

[0004] In the prior art, some standing frame devices adjust the angle of the patient's foot through mechanical structure, but there are often problems such as unstable structure, unstable adjustment process or inability to accurately lock the target angle. In addition, some devices cannot provide sufficient support force during adjustment, which may cause the patient to be unstable during use and affect the rehabilitation effect. Therefore, how to optimize the structure design, improve the stability and comfort of use, and reduce the inconvenience during use is still a prominent problem in the prior art.

[0016] The second pin joint holes are arranged through the two end sides of the connecting rod, and the two ends of the connecting rod are respectively pinned to the third pin joint seat and the second pin joint seat.

[0017] Further, the driving rod comprises a fixed rod connected to the gear, a sleeve movably sleeved on the fixed rod, a locking knob provided at the bottom outside of the sleeve, and the position of the sleeve can be locked by screwing the locking knob.

[0018] Further, the fixed rod is sleeved with a limiting piece, and the limiting piece is connected to the transverse rod through a screw.

[0020] Further, the two ends of the transverse rod are fixedly connected with support foot pads below.

[0021] Compared with the prior art, the utility model has the beneficial effects that:

[0022] First, this invention, through the rational structural design of the base, pedal, and linkage components, enables precise and convenient adjustment of the tilt angle during use. Existing devices mentioned in the background art lack precision in their adjustment process or fail to provide users with sufficient flexibility in angle adjustment. This invention, however, through the linkage design of a rack and pinion, ensures the stability and precision of the pedal during adjustment, meeting the rehabilitation needs of different patients. The turntable allows users to easily control the tilt angle changes, thereby enabling effective correction and rehabilitation exercises for the feet, particularly showing outstanding effects in the treatment of problems such as foot eversion, foot drop, and ankle deformities.

[0023] Secondly, the anti-slip protrusions and baffles on the pedal effectively improve safety during use. In existing technologies, some devices suffer from pedal slippage and instability, which can easily lead to discomfort or accidents for the patient during adjustment. This invention, however, significantly enhances the stability of the patient's feet through evenly distributed anti-slip protrusions and fixedly connected baffles on the pedal, effectively preventing slippage and ensuring safety and comfort during rehabilitation training.

[0024] Furthermore, the design of the linkage component, through the cooperation of the connecting rod and rack, avoids instability and unevenness during adjustment. Addressing the structural instability issues that may occur during adjustment in existing equipment mentioned in the background art, this invention ensures stable connections between components through precise pin-fitting seats and pin holes, thereby improving the reliability of the equipment during long-term use.

[0025] Furthermore, the adjustment function of the drive rod has been innovatively improved in this invention. By setting a locking knob and a limiting component, users can easily lock the adjustment position, preventing loosening and instability during the adjustment process. Addressing the problems of inconvenient operation and easy loosening of existing equipment mentioned in the background art, this invention, through this design, ensures that the standing frame remains stable throughout the adjustment process, thereby enhancing the durability and safety of the equipment.

[0026] Finally, the design of the base and supporting feet increases the overall stability of the standing frame, solving the problem of equipment instability in existing technologies. The supporting feet effectively increase the friction between the equipment and the ground, preventing the equipment from sliding or tilting during use and ensuring the safety of users during rehabilitation training.

[0048] Referring to Figures 1-2 The structural design of base 1 includes two longitudinally arranged longitudinal rods 11, and the two ends of longitudinal rod 11 are fixedly connected with transverse rod 12. The longitudinal rod 11 forms a stable support structure by fixed connection, providing sufficient stability for the entire standing frame. The upper end of one end of longitudinal rod 11 is fixedly connected with first pin seat 111 for rotatably connecting with first pin hole 21 of pedal 2. The rotatable connection achieved by the pin can ensure smooth rotation of pedal 2 during adjustment and ensure stable and durable connection between pedal 2 and base 1.

[0049] Referring to Figures 2-4 The upper end of one end of pedal 2 is fixedly connected with baffle 23, which can effectively limit the sliding of the user's feet when standing, thereby ensuring safe use. The upper end of pedal 2 is evenly distributed with anti-skid convex grains 24, which can provide better friction during use, effectively preventing the user's feet from sliding, and further improving the safety and comfort of use.

[0050] Referring to Figures 2-4 The lower end of pedal 2 is fixedly connected with second pin seat 22; the upper end of one end of rack 31 is fixedly connected with third pin seat 311; the two ends of connecting rod 32 are provided with second pin hole 321 on the side surface, and the two ends of connecting rod 32 are respectively pinned on third pin seat 311 and second pin seat 22.
