[0040] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0041] refer to Figures 1 to 12 As shown, a therapeutic device includes a therapeutic device base 1, a first adjustment mechanism 2 connected to the therapeutic device base 1, a second adjustment mechanism 3 connected to the first adjustment mechanism 2, and a therapeutic device head 4 installed at one end of the second adjustment mechanism 3; the first adjustment mechanism 2 includes an adjustment seat 21 and a rotating arm 22 rotatably connected to the adjustment seat 21, the adjustment seat 21 being connected to the therapeutic device base 1, and the other end of the second adjustment mechanism 3 being rotatably connected to the rotating arm 22.

[0042] Specifically, the treatment head 4 can be made of various instruments or devices with therapeutic and lighting effects, such as the treatment head of an electromagnetic wave therapy device, the treatment head of a moxibustion device, the treatment head of an infrared therapy device, the lamp head of a medical heating lamp, the treatment head of a specific electromagnetic wave therapy device, etc., as needed.

[0043] like Figure 1 and Figure 3 As shown, in actual use, the position of the treatment head 4 is adjusted by rotating the arm 22 in the first adjustment mechanism 2 relative to the adjustment seat 21 and by adjusting the rotation angle of the second adjustment mechanism 3 relative to the arm 22, so that the treatment head 4 is in an appropriate position to treat the patient.

[0044] This therapeutic device employs a dual adjustment mechanism, consisting of a first adjustment mechanism 2 and a second adjustment mechanism 3. Adjustment is achieved simply by manually rotating the device to the desired position, making it convenient and flexible. Compared to existing far-infrared therapy lamps and other therapeutic devices, it not only boasts a compact structure and lower production and maintenance costs, but also offers superior ease and flexibility in adjustment, making it highly practical.

[0045] In this embodiment, the adjusting seat 21 includes a seat housing 211 and a gear component 212 disposed within the seat housing 211; the rotating arm 22 includes an arm body 221 rotatably connected to the seat housing 211, a button component 222 rotatably disposed on the arm body 221, a retaining shaft 223 disposed on one end of the button component 222 near the gear component 212, and a return spring 224 for driving the button component 222 to rotate so that the retaining shaft 223 engages in one of the tooth grooves of the gear component 212.

[0046] In practical applications, the reset spring (224) can be used to rotate the button (222) by abutting one end of the button (222), or by pulling the button (222) to rotate the button (222).

[0047] Specifically, one end of the button 222 and the arm 221 extends into the housing 211, and the retaining pin 223 engages with one of the tooth slots of the gear 212. The other end of the button 222 protrudes from the arm 221, thus locking the adjusting seat 21 and the rotating arm 22. When the angle of the rotating arm 22 needs to be adjusted, pressing the button 222 disengages the retaining pin 223 from the tooth slot of the gear 212. When the rotating arm 22 is rotated to the desired angle, releasing the button 222 causes the retaining pin 223 to engage with the other tooth slot of the gear 212 under the action of the spring, thus locking it in place. This engagement structure of the retaining pin 223 and the gear 212 allows for a wide range of adjustment of the rotating arm 22 from approximately 0 degrees to 90 degrees. This not only makes adjustment convenient and locking reliable but also significantly improves the adjustable range of the treatment head 4.

[0048] In this embodiment, the seat housing 211 is provided with a rotating groove 210 communicating with the interior of the seat housing 211. A retaining ring 5 for blocking the rotating groove 210 is movably disposed inside the seat housing 211. A retaining plate 6 is provided on the inner side of the retaining ring 5. The retaining ring 5 is provided with a retaining ring protrusion 51 for pushing the retaining plate 6 to move. The retaining ring 5 is provided with a retaining ring through hole 52 for the arm 221 and the button 222 to pass through. One end of the arm 221 and the button 222 extends into the seat housing 211 after passing through the rotating groove 210 and the retaining ring through hole 52.

[0049] like Figures 5 to 9 As shown, when the angle of the rotating arm 22 is adjusted, the rotating arm 22 rotates within the rotating groove 210, which guides and limits the rotation of the arm 22. When the rotating arm 22 rotates, the arm body 221 and the button component 222 drive the retaining ring 5 to rotate, and the retaining ring protrusion 51 drives the baffle 6 to rotate. When the rotating arm 22 rotates clockwise, the retaining ring protrusion 51 drives the baffle 6 to rotate, sealing the lower hollow portion of the rotating groove 210; when the rotating arm 22 rotates counterclockwise, the arm body 221 and the button component 222 drive the retaining ring 5 to rotate, sealing the upper hollow portion of the rotating groove 210, thereby protecting the internal structure of the housing 211 and improving its service life. Specifically, the retaining ring 5 includes a first retaining ring 53 and a second retaining ring 54 connected to the first retaining ring 53. The retaining ring 5 is constructed by splicing the first retaining ring 53 and the second retaining ring 54, which facilitates processing and manufacturing.

One end of each outer shell 2213 is connected to the base housing 211. Specifically, the mounting plates 2211 and the outer shells 2213 are connected by screws.

[0057] The arm body 221 adopts a structure in which two mounting plates 2211 are installed inside two outer shells 2213, which facilitates the installation of components such as button 222 and return spring 224 in the space between the two mounting plates 2211. The ends of the two mounting plates 2211 that extend into the seat shell 211 are respectively located on both sides of the gear 212, making the structure stable and easy to install. One end of the two outer shells 2213 is connected to the seat shell 211 and fits on the surface of the seat shell 211, making the connection of this therapeutic device reliable and having good integrity and aesthetics.

[0058] In this embodiment, the gear component 212 includes a connecting portion 2121 and two sector-shaped portions 2122 respectively connected to the connecting portion 2121. Multiple tooth grooves are correspondingly provided on the circumference of the two sector-shaped portions 2122. Specifically, the connecting portion 2121 of the mounting rod 11 is fixedly connected. This gear component 212 is easy to install and fix. When the retaining shaft 223 is engaged in the tooth grooves using the two sector-shaped portions 2122, the two tooth grooves provide two-point positioning for the retaining shaft 223, resulting in a smooth and reliable engagement.
