Drawings

FIG. 1 is a front view of a floating reclining device according to an embodiment of the present invention;

FIG. 2 is a side view of a floating reclining device according to embodiments of the present invention;

in the drawings: 1. the device comprises a reverse head, 2, a first spring, 3, a second spring, 4, a lifting plate, 5 and a support.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1 and 2, a structure diagram of a floating reclining device is shown, wherein the structure diagram comprises a reclining head 1, a first spring 2, a second spring 3, a lifting plate 4, a support 5, a pressure sensor and an early warning device; the anti-head 1 that leans on sets up on lifter plate 4, and lifter plate 4 connects support 5, and anti-head 1 is established first spring 2, second spring 3 from inside to outside overlapping in proper order, and the length of first spring 2 is greater than the length of second spring 3, and the biggest spring force of second spring 3 is greater than the biggest spring force of first spring 2, and baroreceptor sets up in the bottom of second spring 3, and baroreceptor and early warning device signal connection.

In this embodiment, the maximum spring force of the first spring 2 is 350N, and the maximum spring force of the second spring 3 is 500N.

In this embodiment, the baroreceptor and the pre-warning device are both devices in the prior art.

The features and functions of the present invention will be further understood from the following description.

During the use, anti-head 1 atress downstream, first spring 2 compression to protect the work piece through the reaction force of first spring 2, anti-head 1 continues downstream, contacts with second spring 3, makes second spring 3 compression, and protects the work piece through the reaction force of first spring 2, second spring 3. And when the pressure value measured by the pressure sensor exceeds a threshold value, the early warning device receives the signal of the pressure sensor and gives an early warning, and the workpiece is further protected by the pressure sensor and the early warning device.

The above is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, and it should be appreciated by those skilled in the art that various equivalent substitutions and obvious changes made in the specification and drawings should be included within the scope of the present invention.
