Abstract

An overturning seat is characterized in that the seat board components comprise a spring jacket 13 installed on a spring 12. A spring bushing 11 is inserted inside the spring. The spring and the spring bushing 11 are installed in a seat axis tube 4 welded with a disc stopper 3 and a lining bush14, which are also inserted inside a seat board 2 of a hollow blow molding plastic seat. The metal holding plate components 5,15 of the seat board and a nylon pad 9 are jacketed inside the seat axis tube 4. The above seat board components are inserted inside a U-shaped groove 30 of a middle support. And a bolt 20, a fixed block 23 and a block stopper 19 are provided. A back plate 1is inserted in the support U-shaped groove 33. When subject to the gravity effect imposed by a human body, the seat board (2) is rotated, in which the seat axis tube (4) is taken as a centre. The spring (12) is toggled through a holding plate fork (35) on the seat board (2) so that the spring (12) can be in elastic deformation. When the human body left, the spring (12) is in the restoration of deformation. With the use of the automatic overturning mechanism of the seat board, the horizontal seating area is reduced, so that the audience is given more easy access.

Description

Turning-over plate chair

Technical field: the utility model relates to the Turning-over plate chair of usefulness such as gymnasium, Movie House and Conference Room.

Background technology: the seat turnover panel complex structure of prior art.

Summary of the invention: the purpose of this utility model is to overcome the baroque problem of prior art turnover panel, and a kind of Turning-over plate chair simple in structure is provided.

Turning-over plate chair comprises swinging mounting, it is characterized in that:

Seat board component comprises: spring protecting sleeve (13) is positioned on the spring (12), spring bushing (11) inserts in the spring (12), spring (12), spring bushing (11) are packed into and are welded with the seat beam barrel (4) and the lining (14) of arresting disc (3), and insert in the hollow blow molding seat seat board (2), seat board scisse assembly (5,15) and nylon spacer (9) cover are taken a seat in the beam barrel (4), the yielding rubber (10) of between seat board (2) and seat board scisse assembly (5,15), packing into, screw (38) is connected firmly interior embedded nut of seat board (2) and scisse assembly (5,15);

Above-mentioned seat board component is inserted in the U-lag (30) of middle support (18), scotch (19) is inserted in the groove (31), fixed block (23) is inserted in the groove (32), bolt (20) is fixed block (23), scotch (19) fixedly, it is fastening that the end of a beam barrel (4) is fixed in the U-lag (30) of middle support (18), and seat yielding rubber block (24) is inserted in the dovetail groove (34) and compresses with bolt (17), pad (21).

Backboard (1) insert to support in the U-lag (33), and has slotted hole support pad place at four and with bolt (25), pad (26), plain cushion (27) embedded nut in the backboard (1) is connected firmly.

Operation principle: seat board supporting spring (5,15) and shift fork (35) are near steel wire one end of spring (12), the other end of spring steel wire is gone up scotch (36) near seat beam barrel (4), this moment, spring (12) torsion overcame seat board (2) upset downwards, kept seat board (2) to stop in original position.Owing to support in the square groove (30) about seat beam barrel (4) is stuck in all the time, do not rotate, when being subjected to the gravity that human body applies, seat board (2) does the time spent, seat board (2) is the center rotation with seat beam barrel (4), supporting spring shift fork (35) on the seat board (2) is stirred spring (12) makes spring (12) that strain take place, when turning to the last scotch (37) of seat board supporting spring (5,15), seat board (12) contacts with the last yielding rubber block (24) of left and right, middle support (8,22,18), during interaction, seat board (2) stop motion.Human body gravity is sent to ground by the interaction force of seat board supporting spring (5,15) and left and right, middle support (8,22,18).When human body leaves the seat, gravity discharges, and spring (12) returns seat board (2) when turning to certain position in recovering deformation process, and spring (12) torsional moment and seat board (2) are when gravitational moment equates, seat board (2) revolution stops, and keeps seat board (2) to stop in original position.

Embodiment: installation process:

1, unwrapping wire punching: with the seat distribution map is foundation, confirm every row's quantity after, (seat is apart from the hole of * 117mm) line, and electricity consumption hammering φ 11.5, hole depth 70mm press expansion bolt (16) centre-to-centre spacing.

2, mounting bracket: M10 * 100 expansion bolts (16) are poured in φ 11.5 holes with punching pin, the expansion tube upper surface is concordant with cement step horizontal plane, support is inserted in is with plain washer, spring bullet circle and acorn nut in the expansion bolt, will support (8,18,22) and install firmly.

3, seat board component assembling: at first spring protecting sleeve (13) is positioned on the spring (12), again spring bushing (11) is inserted in the spring, pack into then and be welded with in the seat beam barrel (4) and lining (14) of arresting disc (3), and insert in the hollow blow molding seat seat board (2), afterwards seat board scisse assembly (5,15) and nylon spacer (9) are overlapped in the beam barrel (4) of taking a seat, the yielding rubber (10) of packing between seat board (2) and seat board scisse assembly (5,15) uses screw (38) that interior embedded nut of seat board (2) and scisse assembly (5,15) are connected firmly then;

4, seat board is installed: the seat board component that assembles is inserted support in the U-lag (30), with scotch (19) insertion groove (31), with fixed block (23) insertion groove (32), fixing with bolt (20), will also compress in seat yielding rubber block (24) the insertion dovetail groove (34) with bolt (17), pad (21).
