Auditorium chairs are composed of four parts: seat, back, armrests and standing feet, and are suitable for use in auditoriums, theatres, lecture halls and other places. Under normal circumstances, the standing feet and armrests are integrated to form a firmly installed armrest frame, and its composition structure is generally steel and wood or steel and plastic structure. Existing auditorium chair manufacturers produce auditorium seats that generally adopt the structural design of a rotating storage writing board. For example, some auditorium chair manufacturers produce auditorium chairs that store writing boards within the armrests, while the armrests are designed to be rotatably attached to the top of the armrests. When in use, the armrest plate is turned to the left or right and then the writing tablet is removed from the armrest by a swivel operation that rotates the support bars at the bottom of the writing tablet until they press against the armrest, causing the armrest to strongly support the writing tablet and thus encourage it to be placed horizontally in front of the armrest. However, such auditorium chairs produced by auditorium chair manufacturers are bulky in structure, inconvenient in operation and costly, and often require the design of a rotating mechanism to achieve a rotating connection between the armrest plate and the armrest, which is very inconvenient when picking up and placing the writing board. Moreover, a complex structured rotating connection mechanism is used between the support bar and the writing board to enable the writing board to rotate and achieve clamping relative to the support bar, thus enabling the writing board to rotate from a vertical to a horizontal state.
In response to the shortcomings of the prior art, our auditorium chair manufacturer provides an auditorium chair with simple and feasible structure, novel and unique design, stable and reliable working, easy to use, easy to disassemble and install, save a lot of materials, low cost, beautiful and durable, in order to solve the problems of bulky structure, inconvenient operation and troublesome installation of auditorium chair in the prior art. In order to achieve the above purpose, our auditorium chair manufacturers produced using the following technical solutions: an auditorium chair, consisting of a chair back, seat, armrest, standing feet and a writing board set on the front side of the armrest; armrest is provided with an armrest board; wherein the writing board is provided with a round rod; the front end of the round rod is axially fixed horizontally at the bottom of the writing board; the rear end of the round rod is provided with a cylindrical guide block fixed vertically at one end; the armrest has a forward The rotating body is provided with a circular hole suitable for inserting into the rear end of the round rod and a guide hole for the guide block to rotate through; the axial direction of the circular hole is perpendicular to the axial direction of the rotating body; the guide hole is set at the top of the rotating body and is connected to the circular hole; in use, the rear end of the round rod is located outside the circular hole and close to the armrest, and the guide block is in an axially horizontal position and close to the rotor; in the spectator seat, the outer peripheral surface of the rotor is in contact with the inner peripheral surface of the cavity; the width of the opening is adapted to the diameter of the round bar. One end of the clamping section is connected to the bottom end of the connecting section; the bottom surface of the armrest plate is attached to the top surface of the armrest when the clamping section is stuck into the clamping inlet and against the upper inner wall surface of the housing cavity.
In addition, the armrest is provided with a holding cavity with the opening facing forward, allowing the writing board to be easily accommodated vertically in the holding cavity, with simple operation and without the need to open the armrest panel, avoiding the impact on people in adjacent positions when removing and placing the writing board.
Through such a delicate structural design, the overall structure of the auditorium chair produced by our auditorium chair manufacturer can be greatly simplified, saving materials and reducing costs. In addition, the top surface of the armrest is provided with a card entrance that is connected to the accommodation cavity, and the card block set on the armrest board is correspondingly inserted into the card entrance, so that the armrest board is connected to the armrest, which is convenient to disassemble and easy to maintain.
