Description

Technical Field

[0001] This technical solution belongs to the field of fitness equipment technology, specifically a height-adjustable back massager. Background Technology

[0002] Most back massagers on the market are currently of a fixed design, with their massage heads or panels typically mounted on a support frame, and the overall height is not adjustable. While these massagers can provide some degree of back massage, the fixed height often makes it difficult for them to accurately fit the user's back area due to differences in height, posture, and body type.

[0003] In actual use, some users may experience discomfort or discomfort due to differences in height, causing the massager to be positioned off-target. This can affect the massage effect and even cause discomfort. Some users also have to adjust their sitting or body posture to fit the fixed height of the massager, increasing the burden of use and reducing comfort and convenience.

[0004] In summary, existing back massagers are all fixed structures and lack height adjustment functions, making it difficult to meet the personalized needs of users with different heights and usage habits. This results in limited massage effects and insufficient comfort. There is an urgent need for a back massager that can flexibly adjust the height according to the user's needs to solve the above problems. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the present invention discloses the following technical solution; A height-adjustable back massager, comprising: First support column: A guide rod is fixed on one side of the first support column, and a back massager is slidably connected to the guide rod so that the back massager can slide up and down on the guide rod; Second support column: The second support column is located on the other side of the first support column; Single lever: The single lever is a hollow single lever, and the two ends of the single lever are respectively fixed to the top of the first support column and the second support column, and connect the internal space of the first support column and the second support column; Adjustment device; the back massager is also equipped with an adjustment device for adjusting and fixing the position of the back massager on the guide rod.

[0006] Furthermore, as one embodiment, the back massager is connected to the guide rod by a hoop, and the adjustment device is installed on the hoop at the connection between the back massager and the guide rod. The adjustment device is an eccentric wheel quick clamping device, which includes an eccentric cam with a wrench handle, so that the position of the back massager on the guide rod can be adjusted by adjusting the wrench. Its principle is the same as that of the quick release device used for bicycle seat height adjustment.

[0007] Furthermore, as another embodiment, the back massager is provided with a linear bearing, which is connected to a guide rod, so that the back massager can move up and down on the guide rod via the linear bearing.

[0008] Furthermore, the guide rod is a round rod.

[0009] Furthermore, the first support column is provided with a guide groove, and the back massager is provided with a guide rod along the guide rod direction. A linear bearing is fixedly installed on the guide rod and connected to the guide rod. The end of the guide rod is inserted into the guide groove so that the end of the guide rod is located inside the first support column. A pull rope is connected to the guide rod so that the back massager can be controlled to move up and down by pulling the rope.

[0010] Furthermore, there are two guide rods, namely an upper guide rod and a lower guide rod.

[0011] Furthermore, the inventors discovered that while existing adjustable devices such as quick-release mechanisms can adjust the height of the massager, they still suffer from problems such as excessively long adjustment times and poor comfort. To solve this technical problem, the inventors fixed an adjustable tension cylinder to the side of the first support column opposite to the guide rod fixing surface. A pull rope is connected to the top of the adjustable tension cylinder. A first pulley is fixed to the side of the first support column opposite to the guide rod fixing surface; the pulley is positioned higher than the top of the adjustable tension cylinder. A second pulley is located inside the first support column, positioned lower than the first pulley. This allows the pull rope to connect to the end of the lower guide rod via the first and second pulleys, starting from the top of the tension cylinder. A tension gas spring is fixed inside the second support column, and a pull rope is connected to the top of the tension gas spring. The single lever inside... A guide wheel is provided at the turning point, allowing the pull rope to start from the top of the tension air spring, pass through the guide wheel, pass through the single lever, enter the first support column, and connect to the end of the upper guide rod. This allows the back massager to move up and down by controlling the extension length of the piston rod in the adjustable tension cylinder. The cylinder control device can be installed on the first support column, allowing the user to control the extension and retraction of the cylinder to adjust the up and down position of the massager. The extension and retraction of the cylinder can be controlled by a solenoid valve or a control panel. The cylinder can be powered by a battery or a solar panel, whichever is appropriate for those skilled in the art. After adjusting the position of the back massager using this mechanism, the back massager can also move up and down slightly according to the user's back movements during use, further enhancing the user experience.

[0012] Preferably, the pull rope is a steel cable.

[0013] Furthermore, the first or second support column is equipped with a scale; the first or second support column is also equipped with a height-to-recommended massager height chart. The guide rod is also equipped with a scale, allowing the user to adjust the massager's height according to the chart and the scale. Furthermore, the first support column also includes a protective cover, which is fixed to the outside of the adjustable tension cylinder and covers it. The top of the protective cover has a through hole through which the pull rope can pass. The protective cover not only protects the adjustable tension cylinder, but also serves as a footrest to help shorter people reach the single lever more easily by stepping on the protective cover.

[0014] The method of using this application is as follows: Securely fix the first and second support columns to the ground or support base to ensure the overall frame is stable. Check that the connections of the guide rod, linear bearing, guide rod, and pull rope are secure. Confirm that the adjustable tension cylinder and tension air spring are in normal working condition. If the cylinder extension and retraction is controlled by a solenoid valve or control panel, the power supply must be connected first. Battery power or solar panel power can be selected. Users can operate the adjustable tension cylinder via the control panel or cylinder control device to extend or retract its piston rod, thereby driving the pull rope and pulley assembly. When the piston rod retracts, it extends the length of the tension air spring. When the piston rod extends, the tension air spring automatically retracts, allowing the back massager to move up and down along the guide rod. During adjustment, the linear bearing and guide rod work together to ensure smooth sliding of the massager, avoiding shaking and deviation. After adjusting the back massager to a suitable height, the user can lock the position via the control device to ensure the massager remains stable during use.

[0015] For shorter users, the single lever can be more easily reached by stepping on the protective cover on the outside of the first support column, thus improving its ease of use. The protective cover also protects the adjustable tension cylinder from external impacts or dust.

[0016] The aforementioned tension gas spring is a gas spring that is in a shortened state when at rest and requires external force to stretch; once the external force is reduced or released, it will automatically retract. It is also called a reverse gas spring or tension gas spring.

[0017] Compared with the prior art, the present invention has the following outstanding advantages: 1. This application, by setting a back massager on the guide rod and combining it with an adjustable tension cylinder, pulley system and tension air spring, enables the back massager to be flexibly and smoothly adjusted in height, making it suitable for users of different heights, different sitting postures or different body types, thus greatly improving the applicability of the device.

[0018] 2. This application uses a cylinder telescopic control to control the height of the massager, which can be adjusted via a solenoid valve or control panel, avoiding the cumbersome steps of traditional manual adjustment, allowing users to easily set the height and significantly improving ease of use.

[0019] 3. The cooperation between the linear bearing and the guide rod ensures the stability of the back massager during movement, avoiding problems such as shaking and deviation, so that the massage area can accurately correspond to the target area on the user's back, ensuring the massage effect.

[0020] 4. During use, the back massager can move slightly with the natural rise and fall of the user's back, thereby achieving dynamic fit and avoiding the feeling of misalignment caused by slight changes in the position of the back, thus improving the comfort during continuous use.

[0021] 5. By installing a protective cover on the outside of the first support column, this application not only effectively prevents external forces from damaging the adjustable tension cylinder, improving the safety and durability of the device, but also provides a through hole at the top for the pull rope to pass through smoothly. In addition, the protective cover structure can also be used as an auxiliary footrest, allowing shorter users to more easily reach the single lever by stepping on the protective cover, thereby improving the device's ergonomics and ease of use.
