Detailed Description

To further clarify the technical solutions and effects adopted by the present application to achieve the intended purpose, the following detailed description is given with reference to the accompanying drawings and preferred embodiments according to the present application. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

As shown in fig. 1-2, the utility model discloses a seat plate buffer mechanism, which comprises a fixed bracket 1 and a seat plate 2 hinged on the fixed bracket 1, wherein a buffer mechanism is arranged between the seat plate 2 and the fixed bracket 1, and comprises an elastic reset piece 3 and a damper 4; when the elastic reset piece 3 drives the seat plate 2 to reset and rotate, the damper 4 applies acting force to the seat plate 2 to buffer the reset rotation of the seat plate 2.

The seat board 2 of the present invention has a use state and a reset state, and generally, the seat board 2 in the reset state is in a vertical state, and when in use, a user can sit on the seat board 2 by turning the seat board to a horizontal state. When the use is finished, the user leaves, and the elastic resetting piece 3 can drive the seat plate 2 to automatically reset and rotate, so that the damper 4 applies acting force to the seat plate 2 to buffer the resetting and rotating of the seat plate 2.

Therefore, when the elastic reset piece 3 drives the seat plate 2 to reset to rotate relative to the fixed support 1 through the arranged buffer mechanism, the damper 4 structure is utilized to replace the traditional mode of adopting a pneumatic support rod as a buffer structure, so as to additionally apply acting force to the seat plate 2, thereby reducing the speed of the seat plate 2 during rotation, realizing the buffer effect and effectively ensuring the reset of the seat plate 2.

The fixing support 1 is hinged with the seat plate 2 through a shaft hole structure, and the shaft hole structure comprises first through holes respectively formed in two sides of the fixing support 1 and a pin shaft 5 arranged on the seat plate 2 and connected with the first through holes in a penetrating mode; the damper 4 comprises a damper body 41 which is connected on the pin shaft 5 in a penetrating way and rotates along with the pin shaft 5 and a base 42 which is connected on the pin shaft 5 in a penetrating way and is fixedly connected with the fixed support 1; elasticity piece 3 that resets is the torsional spring, is provided with round pin axle sleeve 6 between torsional spring and the round pin axle 5, and the one end of round pin axle sleeve 6 links to each other with fixed bolster 1 is fixed, and the torsional spring is worn to establish on round pin axle sleeve 6 and the one end butt of torsional spring on fixed bolster 1, and the other end butt of torsional spring is on bedplate 2. In this embodiment, fixed bolster 1 is the U-shaped, and first via hole sets up respectively on the both sides of fixed bolster 1 found the arm, and attenuator body 41 and base 42 set up on one side found the arm, and round pin axle sleeve 6 sets up on the arm is found to the opposite side, and round pin axle 5 passes round pin axle sleeve 6, attenuator body 41 and base 42 in proper order. When the torsion spring drives the seat plate 2 to reset and rotate, the seat plate 2 drives the pin 5 to rotate, and the pin 5 drives the damper body 41 to rotate relative to the base 42. The benefit that so set up lies in, realizes that round pin axle 5, torsional spring, round pin axle sleeve 6, attenuator body 41 and base 42 are concentric setting and its structure compacter, and concentric being provided with does benefit to the axle center that ensures round pin axle 5, torsional spring, attenuator body 41 and bedplate 2 the same, effect when the guarantee rotates.
