DETAILED DESCRIPTION

[0019] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0020] In order to solve the above problems of the existing desks and chairs, the present invention provides a new rocking desk and chair.

[0021] Please refer to Figure 1 , Figure 1 An exploded view of the rocking desk and chair provided in an embodiment of the present application.

[0022] The present application provides a rocking desk and chair, which comprises: a seat assembly, a backrest assembly, a base assembly, a front rocking assembly, and a rear rocking assembly; the backrest assembly is connected to the rear rocking assembly, the upper end of the rear rocking assembly is rotatably connected to the rear end of the seat assembly and is used to drive the rear end of the seat assembly to move, and the lower end is rotatably connected to the base assembly, the upper end of the front rocking assembly is rotatably connected to the middle part of the seat assembly, and the lower end is rotatably connected to the base assembly, a damping mechanism is arranged in the base assembly, a fixed end is rotatably connected to the base assembly, and a movable end is connected to the rear rocking assembly;

[0023] When the seat assembly loses external force, the rear part of the seat assembly moves upward due to the upward force of the rear swing assembly, the damping mechanism contracts, and the rear swing assembly swings in the opposite direction of the contraction force, thereby driving the front swing assembly to swing in the same direction.

[0024] In the prior art, conventional desks and chairs are generally fixed structures, and some are foldable and recoverable desks and chairs. However, the existing foldable and recoverable desks and chairs all use a gravity recovery structure, which relies on the weight of the rear end of the seat plate to recover. The gravity recovery mechanism recovers too quickly, makes too much noise, and has a single form. Compared with the prior art, the present application provides a swinging desk and chair. When the seat assembly loses external force, the rear part of the seat assembly moves upward due to the upward force of the rear swing assembly, the damping mechanism contracts, and the rear swing assembly swings in the opposite direction of the contraction force, thereby driving the front swing assembly to swing in the same direction, solving the problem of limited classroom space. When passing through traditional desks and chairs, students must stand up and give way to others. Students in the seats only need to swing forward, and students who want to pass can easily pass from behind.

[0025] In one embodiment, the seat assembly includes a seat plate 22 and a seat plate bracket 17 connected to the bottom of the seat plate, and the seat plate 22 and the seat plate bracket 17 are fastened together by M6 screws.
