Description

Technical Field

[0001] This utility model belongs to the technical field of tension regulators, specifically relating to a multi-level, multi-rib adjustable torque tension regulator. Background Technology

[0002] Horizontal bar exercises are a highly effective rehabilitation therapy. Through movements such as suspension and pull-ups, horizontal bar exercises can effectively relieve lower back pain, help restore the natural curvature of the spine, enhance spinal health, and promote overall coordination and flexibility. However, horizontal bar exercises also have certain limitations, especially in traction training. Horizontal bars are mainly used for static traction, and the monotonous exercise can easily cause discomfort. Although they can relieve spinal pressure and stretch muscles, they lack the continuity and elasticity of dynamic traction. Unlike dynamic traction, they cannot more comprehensively activate muscles and joints through exercise stimulation. Therefore, they are difficult to use to alleviate or eliminate discomfort caused by cervical, lumbar, and spinal compression due to prolonged sitting, standing, prolonged desk work, monotonous or repetitive movements, or monotonous occupational habits.

[0003] The inventor's prior invention patent CN119925873A discloses an elastic horizontal bar, specifically disclosing that an elastic device enables the cervical traction mechanism to have a certain degree of flexibility, allowing the user's cervical spine to be suspended. This allows for simultaneous exercise and rehabilitation of the lumbar and cervical spine. However, existing elastic devices mostly use spring structures with fixed spring coefficients, making it difficult to finely adjust the torque according to the user's weight, rehabilitation stage, or specific location (such as the cervical or lumbar spine). Limited adjustment can only be achieved by replacing springs of different specifications, failing to meet personalized rehabilitation needs. Furthermore, the elasticity decays, making it difficult to quickly adjust or replace the spring, affecting the reliability of long-term use. Moreover, the linear tension characteristics of the spring are difficult to match the nonlinear mechanical requirements of the dynamic movement of the spine, thus limiting further improvement in rehabilitation effects.

[0004] Therefore, there is an urgent need for a multi-level, multi-ribbed adjustable torque tension adjuster that can achieve multiple fine adjustments, has a stable structure, and whose tension characteristics are more in line with the physiological needs of the human body, so as to meet the needs of users of elastic horizontal bars at different stages of rehabilitation. Utility Model Content

[0005] In view of this, the present invention provides a multi-level, multi-rib adjustable torque tension adjuster. The present invention allows users to select and activate different numbers or positions of rubber bands according to their own needs, such as weight and rehabilitation stage, to achieve multi-level adjustment of tension and torque, significantly improving the adaptability of the elastic bar cervical traction mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-level, multi-ribbed adjustable torque tension adjuster includes an adjusting mechanism, several rubber bands, and a hanging ring. The hanging ring is arranged above and below the adjusting mechanism and is connected to the adjusting mechanism by multiple rubber bands. The overall outline of the adjusting mechanism is a columnar body, including two arc-shaped plates and an adjusting plate. Several adjusting pins are vertically arranged on opposite sides of the adjusting plate, and each rubber band is independently suspended on an adjusting pin. The arc-shaped plates cover the two sides of the adjusting plate where the rubber bands are suspended.

[0007] Furthermore, the front and rear sides of the adjustment plate are provided with snap-fit ​​grooves, and the arc-shaped plate is provided with snap-fit ​​protrusions corresponding to the snap-fit ​​grooves. The arc-shaped plate is snapped into the snap-fit ​​groove of the adjustment plate through the snap-fit ​​protrusions.

[0008] Furthermore, the interior of the arc-shaped plate is provided with several horizontal baffles arranged vertically, which are located above and below the adjusting pin to prevent the rubber band from coming out.

[0009] Furthermore, the length of the transverse baffle is one-third of the inner diameter of the arc-shaped plate.

[0010] Furthermore, the top and bottom of the adjustment plate are provided with semi-circular cover plates, and guide holes are arranged on one side of the upper cover plate corresponding to the adjustment plate and the other side of the lower cover plate corresponding to the adjustment plate.

[0011] Furthermore, the surface of the rubber band located outside the adjustment mechanism is covered with a protective sleeve.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model uses multiple vertically arranged adjusting pins on an adjusting plate, along with multiple independently suspended rubber bands. Users can select and activate different numbers or positions of rubber bands according to their own needs, such as weight and rehabilitation stage, to achieve multi-level adjustment of the tension, significantly improving adaptability. The combined use of multiple rubber bands provides non-linear elastic buffering characteristics (the tension changes in a step-like or gradual manner as the stretching length increases), which is closer to the elastic support mode of the human spine in natural activities. It can more comprehensively stimulate muscles and joints and enhance the rehabilitation effect of dynamic traction on the cervical and lumbar spine.

[0013] 2. The transverse baffle inside the adjusting plate of this utility model can prevent the rubber band from coming out. Together with the snap-fit ​​structure between the arc plate and the adjusting plate, it forms an effective wrapping and fixing of the rubber band, preventing internal components from loosening or falling off due to movement, and improving the overall structural stability. At the same time, the protective sleeve on the outside of the rubber band can reduce friction loss and the risk of aging and breakage, and extend the service life of the device.
