Description

Technical Field

[0001] The utility model relates to the technical field of dining table backrests, in particular to a dining table backrest. Background Art

[0002] The dining table in the canteen is generally fixed with a table board and a table and chairs. The existing canteen dining table is generally equipped with four tables and chairs on a table board, and the table board and the table and chairs are fixedly connected by a mounting frame.

[0003] The existing publication number CN220001162U discloses a canteen dining table with a reliable backrest, which relates to the technical field of dining tables and includes a fixed frame, a support rod is fixed in the middle of the fixed frame, a horizontal table board is supported on the top of the support rod, a plurality of seat boards are symmetrically installed on the fixed frame about the table board, a vertical back board is fixed on the side of the seat board away from the table board, a mounting opening is opened in the middle of the back board, two horizontal parallel massage rollers are rotatably installed in the mounting opening, and two rotating shafts which are respectively plugged and fixed to the ends of the two massage rollers are rotatably installed inside one side of the mounting opening, transmission wheels are fixed on the two rotating shafts, a transmission belt is commonly sleeved on the two transmission wheels, and a motor is connected to one of the two rotating shafts; the massage rollers can be used to perform periodic contact massage on the backs of employees or students sitting on the seat board and leaning on the back board, thereby greatly alleviating the fatigue of employees and students.

[0004] Although the existing chairs can alleviate the fatigue of employees and students, since the backrest of the chair is fixed vertically, when the user leans back, it cannot adapt to the angle of the user's back, resulting in poor comfort. For this reason, we propose a dining table backrest. Utility Model Content
