Since the abdominal support member needs to be adjusted in angle as needed during treatment or sitting to better support the abdomen or lower back of the person being treated or sitting, a simple, reliable, and easily adjustable adjustment mechanism is required to adapt to the "Chair and Pressing Device" disclosed in the aforementioned patent.

[0003] The technical problem to be solved by this utility model is: how to provide an abdominal support adjustment mechanism that is simple in structure, reliable, and easy to adjust. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an abdominal support adjustment mechanism, which has the characteristics of simple and reliable structure and convenient adjustment.

[0005] The technical solution adopted by this utility model is as follows: an abdominal support adjustment mechanism, including a base and an abdominal support member, and further including a mounting seat and a hinge seat hinged to the base. One end of the hinge seat is hinged to the base, and the other end is hinged to the mounting seat. The other end of the mounting seat is hinged to the base. The abdominal support member is mounted on the mounting seat. A gas strut is connected between the hinge seat and the base. One end of the gas strut is hinged to the hinge seat, and the other end is hinged to the base. A release key is provided on the gas strut.

[0006] The abdominal support adjustment mechanism of this application has a base fixed to the frame of the seat. When adjusting, press the release button, and then move the mounting seat (abdominal support) as needed to adjust its relative angle with the base. The gas strut extends or shortens synchronously. After the angle is adjusted, release the release button, and the length of the gas strut is locked and remains unchanged, so that the relative angle between the mounting seat (abdominal support) and the base remains unchanged. The structure is simple and reliable, and the adjustment is convenient.

[0007] In some embodiments, the gas strut includes a cylinder and a telescopic rod, the telescopic rod being slidably sleeved with the cylinder, the cylinder being hinged with a hinge seat, the telescopic rod being hinged with a base, and a release key being located at the end of the telescopic rod away from the cylinder.

[0008] By adopting the above technical solution, the release button is located at the end of the telescopic rod, which makes it easier to press the release button to adjust the length of the telescopic rod extending out of the cylinder, thereby adjusting the angle of the abdominal support component, making the adjustment more convenient.

[0009] In some embodiments, a rotating seat is fitted onto the outer surface of the end of the telescopic rod away from the cylinder body, and the rotating seat is hinged to the base.

[0010] By adopting the above technical solution and setting a rotating base, it is easy to install and fix the telescopic rod, and the telescopic rod can be hinged to the base.

[0011] In some embodiments, an unlocking component corresponding to the release key is also included. The unlocking component is located at the end of the telescopic rod away from the cylinder body and is hinged to the base. By moving the unlocking component, the unlocking component and the release key can be switched between contact and separation.

[0012] By adopting the above technical solution, the release button can be easily pressed by setting an unlocking component.

[0013] In some embodiments, the unlocking element includes a lever portion and a contact portion, the contact portion being disposed at one end of the lever portion near the release button, the contact portion being disposed at an angle to the lever portion, and the middle portion of the lever portion being hinged to the base.

[0014] By adopting the above technical solution, setting the contact part at an angle perpendicular or nearly perpendicular to the release button increases the contact area and ensures that the contact part and the release button remain in contact during adjustment. Setting the contact part at one end of the lever part can utilize the lever principle to make pressing the release button easier.

[0015] In some implementations, a reset element is connected between the unlocking element and the base, which keeps the unlocking element separated from the release key.

[0016] By adopting the above technical solution, the unlocking component and the release button can be automatically separated when the lever is released, ensuring that the abdominal support will not lose its posture due to accidental contact of the unlocking component and the release button during normal use.

[0017] In some implementations, the reset element is a tension spring.

[0018] In some implementations, the mounting base is located on one side of the base, and the gas strut is located between the base and the mounting base.

[0019] By adopting the above technical solution, the gas strut can be stored between the base and the mounting seat, making the overall structure of the adjustment mechanism more compact.

[0020] In some embodiments, a connecting rod is also connected between the mounting base and the base, with one end of the connecting rod hinged to the end of the mounting base away from the hinge seat, and the other end hinged to the base.

[0021] By adopting the above technical solution and setting up connecting rods, the angle adjustment range of the abdominal support can be increased, enabling it to meet greater user needs.

[0022] In some implementations, there are two connecting rods, which are respectively located on opposite sides of the mounting base. Attached Figure Description

[0031] Please see Figures 1 to 4 An abdominal support adjustment mechanism 100, a preferred embodiment of the present invention, includes a base 10 and an abdominal support member (not shown in the figure), and also includes a mounting seat 20 and a hinge seat 30 hinged to the base 10. One end of the hinge seat 30 is hinged to the base 10, and the other end is hinged to the mounting seat 20. The other end of the mounting seat 20 is hinged to the base 10. The abdominal support member is mounted on the mounting seat 20. A gas strut 40 is connected between the hinge seat 30 and the base 10. One end of the gas strut 40 is hinged to the hinge seat 30, and the other end is hinged to the base 10. A release button 43 is provided on the gas strut 40.

[0032] The abdominal support adjustment mechanism 100 of this application has a base 10 fixed to the frame of the seat. When adjusting, press the release button 43, and then move the mounting seat 20 (abdominal support) as needed to adjust its relative angle with the base 10. The gas strut 40 extends or shortens synchronously. After the angle is adjusted, release the release button 43, and the length of the gas strut 40 is locked and remains unchanged, so that the relative angle between the mounting seat 20 (abdominal support) and the base 10 remains unchanged. The structure is simple and reliable, and the adjustment is convenient.

[0033] like Figure 4 As shown, the gas strut 40 includes a cylinder 41 and a telescopic rod 42. The telescopic rod 42 is slidably sleeved with the cylinder 41. The cylinder 41 is hinged to the hinge seat 30, and the telescopic rod 42 is hinged to the base 10. A release key 43 is located at the end of the telescopic rod 42 away from the cylinder 41. Positioning the release key 43 at the end of the telescopic rod 42 makes it easier to press the release key 43 to adjust the length of the telescopic rod 42 extending from the cylinder 41, thereby adjusting the angle of the abdominal support component, making adjustment more convenient.

[0034] like Figure 3 and Figure 4 As shown, a swivel seat 44 is fitted onto the outer surface of the end of the telescopic rod 42 away from the cylinder body 41, and the swivel seat 44 is hinged to the base 10. By setting the swivel seat 44, it is easy to install and fix the telescopic rod 42, and the telescopic rod 42 can be hinged to the base 10.

[0035] Preferably, to facilitate pressing the release button 43, the abdominal support adjustment mechanism 100 of this application further includes an unlocking member 50 corresponding to the release button 43. The unlocking member 50 is located at the end of the telescopic rod 42 away from the cylinder 41. The unlocking member 50 is hinged to the base 10. By moving the unlocking member 50, the unlocking member 50 and the release button 43 can be switched between contact and separation. By providing the unlocking member 50, it is easy to press the release button 43. By moving the unlocking member 50, the unlocking member 50 contacts the release button 43, and the release button 43 retracts, thereby releasing the lock of the gas strut 40. After releasing the unlocking member 50, the unlocking member 50 no longer applies pressure to the release button 43, and the release member resets, thereby achieving the locking of the gas strut 40.

[0036] Please refer to the following: Figure 4 Specifically, the unlocking component 50 includes a lever portion 51 and a contact portion 52. The contact portion 52 is located at one end of the lever portion 51 near the release button 43, and the contact portion 52 is set at an angle to the lever portion 51. The middle part of the lever portion 51 is hinged to the base 10. Setting the contact portion 52 at an angle perpendicular or nearly perpendicular to the release button 43 increases the contact area, ensuring that the contact portion 52 and the release button 43 remain in contact during adjustment. Positioning the contact portion 52 at one end of the lever portion 51 utilizes the lever principle, making it easier to press the release button 43. To further reduce effort, the hinge point between the lever portion 51 and the base 10 can be positioned close to the contact portion 52.

[0037] Furthermore, a reset member 60 is connected between the unlocking member 50 and the base 10, and the reset member 60 keeps the unlocking member 50 separated from the release button 43. By setting the reset member 60, the unlocking member 50 and the release button 43 can be automatically separated when the lever part 51 is released, ensuring that the abdominal support will not lose its posture due to accidental activation of the unlocking member 50 and the release button 43 during normal use, thus making it more reliable.

[0038] Preferably, the reset member 60 is a tension spring. In other embodiments, other elastic members such as compression springs can also be used, as long as they meet the purpose of separating the contact portion 52 from the release key 43 under the action of the reset member 60 after the unlocking member 50 is released.

[0039] Preferably, the mounting base 20 is disposed on one side of the base 10, and the gas strut 40 is disposed between the base 10 and the mounting base 20. The gas strut 40 can be stored between the base 10 and the mounting base 20, making the overall structure of the adjustment mechanism more compact.

[0040] In one embodiment, a connecting rod 70 is further connected between the mounting base 20 and the base 10. One end of the connecting rod 70 is hinged to the end of the mounting base 20 away from the hinge seat 30, and the other end is hinged to the base 10. By providing the connecting rod 70, the angle adjustment range of the abdominal support can be increased, enabling it to meet greater user needs.

[0041] Furthermore, there are two connecting rods 70, which are respectively set on opposite sides of the mounting base 20. By setting two connecting rods 70, the mounting base 20 can be subjected to more balanced force, and when supporting the user's abdomen, it will not tilt to one side due to uneven force, thus improving the user experience.

[0042] The principle of the abdominal support adjustment mechanism 100 in this application is as follows:

[0043] During adjustment, the lever 51 of the unlocking member 50 is moved so that the contact part 52 contacts the release button 43 of the gas strut 40 and applies pressure. Then, the edge of the abdominal support is held to adjust the angle of the abdominal support as needed. After adjusting to the required angle, the unlocking member 50 is released. Under the action of the reset member 60, the contact part 52 separates from the release button 43, the release button 43 resets, and the length of the gas strut 40 remains locked, thereby locking the angle of the abdominal support and completing the adjustment of the abdominal support.

[0044] Finally, it should be noted that the above description is merely 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.
