Therefore, these terms should not be construed as restrictive interpretations of the content of this application.

[0038] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0039] Example 1:

[0040] like Figures 1-6 As shown, a horizontally adjustable physiotherapy bed includes a bed frame body 100, a backrest body 200, a sliding frame 300, an electric support rod 400, a floating ear assembly 500, and a linkage mechanism 600. The sliding frame 300 is slidably mounted on the bed frame body 100. The sliding frame 300 and the backrest body 200 are connected and linked by the linkage mechanism 600. The floating ear assembly 500 includes a floating ear seat 510, a fixed ear seat 520, a spring guide post 530, and an adjusting spring 540. The fixed ear seat 520 is fixed on the sliding frame 300. The electric support rod 400 is connected to the floating ear seat 510. 10. A spring guide post 530 is connected between the floating ear seat 510 and the fixed ear seat 520. The adjusting spring 540 is sleeved on the spring guide post 530. The extension and retraction of the electric support rod 400 can drive the floating ear seat 510 to move relative to the fixed ear seat 520, and can compress the adjusting spring 540 during the movement. In addition, the introduction of the adjusting spring 540 not only improves the positioning performance of the backrest body 200, but also protects key components such as the electric support rod 400 and the sliding frame 300 from direct impact and wear to a certain extent, extending the service life of the product and reducing maintenance costs.

[0041] The two side plates of the fixed ear seat 520 are provided with long strip holes 521, the floating ear seat 510 and the electric supporting rod 400 are connected through the pin shaft 550 penetrating the long strip holes 521, and the expansion and contraction of the electric supporting rod 400 can drive the floating ear seat 510 to move along the long strip holes 521 relative to the fixed ear seat 520. The long strip holes 521 can ensure that the floating ear seat 510 can move in a certain range. The fixed ear seat 520 is sleeved outside the floating ear seat 510, the bottom plates of the floating ear seat 510 and the fixed ear seat 520 are provided with through holes aligned with each other, the spring guide column 530 is installed in the through holes, one end of the spring guide column 530 is limited to abut against the floating ear seat 510, the other end of the spring guide column 530 penetrates the through hole and extends outward, the adjusting spring 540 is sleeved on the outward extending part of the spring guide column 530, one end of the adjusting spring 540 abuts against the fixed ear seat 520, and the other end of the adjusting spring 540 abuts against the nut 560 screwed on the spring guide column 530. The design that the fixed ear seat 520 is sleeved outside the floating ear seat 510, in combination with the installation mode of the spring guide column 530 and the adjusting spring 540, forms a stable elastic connection structure, the adjusting spring 540 is sleeved on the outward extending part of the spring guide column 530 and is fixed through the nut 560 screwed on the spring guide column 530, and it is ensured that the compression and release of the adjusting spring 540 can be smoothly performed.

[0042] The floating ear seat 510 and the fixed ear seat 520 are both in U-shaped design, the U-shaped design not only increases the strength and stability of the floating ear seat 510 and the fixed ear seat 520, but also facilitates the connection and installation with other components, so that the whole floating ear assembly 500 is compact and reasonable in structure.

[0043] In addition, the two groups of connecting rod mechanisms 600 are symmetrically arranged on the two sides of the back body 200, each group of connecting rod mechanisms 600 comprises a first connecting plate 610 and a second connecting plate 620, one end of the first connecting plate 610 is pinned to the sliding frame 300, the other end of the first connecting plate 610 is pinned to one end of the second connecting plate 620, the other end of the second connecting plate 620 is pinned to the back body 200 and the bed frame body 100, and the first connecting plate 610 and the second connecting plate 620 are connected through pinning, so that the connecting rod mechanism 600 can flexibly rotate and stretch.

[0044] The symmetric arrangement of the two groups of connecting rod mechanisms 600 improves the stability and balance of the back body 200 during rotation.

[0045] The use method of the horizontal stable falling physiotherapy bed is as follows:

[0046] In the operation process, when the driving shaft of the electric support rod 400 extends outward, it pushes the sliding frame 300 to slide to the rear end, and the sliding action is transmitted through the connecting rod mechanism 600, thereby driving the backrest body 200 to stably rise upward; on the contrary, when the driving shaft of the electric support rod 400 is retracted, the electric support rod 400 drives the floating ear seat 510 to move along the long hole 521, and the adjusting spring 540 is completely compressed, and the sliding frame 300 is moved to the front end, and through the linkage action of the connecting rod mechanism 600, the backrest body 200 is slowly lowered until the electric support rod 400 is retracted in place, and the backrest is adjusted to a horizontal state.

[0047] When the backrest is adjusted to a horizontal state, the adjusting spring 540 can still be in a completely compressed state, can be partially compressed, or can not be compressed, and the final compression amount of the adjusting spring 540 depends on the installation error or deviation, and the compression of the adjusting spring 540 can effectively absorb the installation error or deviation, thereby ensuring that the backrest body 200 is accurately and stably lowered to the predetermined horizontal state.

[0048] Embodiment two:

[0049] As shown in Figures 7-10 In this embodiment, the floating ear seat 510 is sleeved outside the fixed ear seat 520, the spring guide column 530 is movably installed between the bottom plate of the floating ear seat 510 and the fixed ear seat 520, the two ends of the spring guide column 530 are provided with limiting portions, the limiting portions can prevent the spring guide column 530 from being separated, the adjusting spring 540 is sleeved on the spring guide column 530, one end of the adjusting spring 540 abuts against the bottom plate of the floating ear seat 510, and the other end of the adjusting spring 540 abuts against the bottom plate of the fixed ear seat 520. The design that the floating ear seat is sleeved outside the fixed ear seat 520, in combination with the limiting portions at the two ends of the spring guide column 530, effectively prevents accidental separation of the spring guide column 530, improves the reliability and safety of the connection, and avoids equipment failure or accidents caused by separation of the spring guide column 530. At the same time, the existence of the limiting portion also limits the movement range of the floating ear seat 510, and ensures stable movement of the floating ear seat 510 in the specified path.

[0050] The utility model utilizes the compression characteristics of the adjusting spring 540, effectively absorbs the error or deviation that can be generated in the installation process, and even if there is a slight deviation in the actual installation of the physiotherapy bed, the adjusting spring 540 can be automatically adjusted through the compression amount, so that the backrest body 200 can accurately and stably reach the predetermined horizontal state when the electric support rod 400 is retracted in place.

[0051] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
