Abstract
The utility model relates to a seat with an automatic slowly lifting mattress, which is designed and developed for portable use. The utility model comprises a seat back, a mattress and seat feet, wherein, the mattress is fixed on the seat feet by rotary shafts. The utility model is characterized in that the utility model is provided with a damping rod which can carry out one-way throttling when liquid is elongated, one end of the damping rod is fixed with a frame of the mattress, and the other end is movably hinged with inward supporting points of the rotary shafts. The damping rod has the structure that the inner part of a liquid cylinder is provided with a piston rod, the piston is provided with a small throttling hole, and simultaneously the piston is provided with a one-way valve which can be opened when the piston is retracted. The utility model has the advantages of portable use, reasonable and simple structure, easy fabrication, etc., and is suitable for popularization on seats.
Description
Technical field
The utility model relates to a kind of technical field that is used for public place seats such as cinema, arenas, assembly hall.
Background technology
The seat that is widely used in public places such as cinema, arenas, assembly hall at present puts down seat in use, and can stand up, pack up, enlarge passage when not using automatically, being beneficial to spectators evacuates, it is manual generally putting down seat cushion, generally realize that by the setting or being provided with of torsion spring of center of gravity seat cushion stands up automatically and pack up seat cushion, its general shortcoming is that seat cushion returns the excessive velocities of turning over, when striking the chair back or other limited blocks, can send impact sound, both influenced spectators' auditory effect, time one length also causes damage to chair easily.There is the inventor to design and develop a kind of seat cushion for this reason and can delays the seat that stands up automatically, it as the patent No. 98224222.0 Chinese patent " a kind of seat cushion can delay the seat that stands up automatically ", it comprises the chair back, seat cushion, chair pin and seat cushion are packed up device automatically, it is characterized in that an air spring that has damping is positioned at the seat cushion inner chamber, one end and the cushion frame of this air spring fix, the other end and seat cushion rotating shaft fix, compared with prior art, when the utility model is packed up automatically at seat cushion, under the damping action of air spring, return lentamente to turn over and pack up until the state of standing up, no longer produce impact noise, adopt the air spring element during its defective, because air spring has interior pressure, so, need certain strength when with seat cushion thing under the hand, therefore operation is not light, and the expense height.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of at prior art to use seat cushion light, easy manufacturing can delay the seat that stands up automatically.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this kind seat cushion can delay the seat that stands up automatically, it includes the chair back, seat cushion, chair pin, seat cushion is fixed on the chair pin by rotating shaft, the damper rod of energy one-way throttle when it is characterized in that having liquid to elongate, one end and cushion frame fix, and inward fulcrum is movably hinged mutually in the other end and the rotating shaft.
As improvement, above-mentioned damper rod is hidden in the seat cushion inner chamber.
Further improve, its structure of above-mentioned damper rod is in the liquid cylinder piston rod to be arranged, and has throttling pore on piston again, the check valve that can open when being provided with retraction piston simultaneously on piston.
Compared with prior art, advantage of the present utility model is: use light, since adopt when having liquid to elongate can one-way throttle damper rod, and the check valve that can open when having designed retraction piston on piston makes the user with under the hand during seat cushion, can open seat cushion by low weight loose ground, avoid the hard defective of air spring, and will pack up seat cushion the time, under the restoring force and damper rod effect of torsion spring, seat cushion rotates around its rotating shaft lentamente, realizes the purpose of slowly standing up; Total simple, manufacturing, with low cost easily reasonable in design is fit to promote the use of on the seat.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1,2,3 illustrate, this kind seat cushion can delay the seat that stands up automatically, it includes the chair back 6, seat cushion 1, chair pin 3, seat cushion 1 is fixed on the chair pin 3 by rotating shaft 2, the damper rod 4 of energy one-way throttle when other has a liquid to elongate, its structure is that liquid cylinder has piston rod 10 for 11 li, on piston, have throttling pore 13, the check valve 14 that can open when on piston, being provided with retraction piston simultaneously, the piston rod 10 of damper rod stretches out the outer end of cylinder and is fixedly connected with cushion frame 7, and inward fulcrum 9 is movably hinged mutually in the damper rod other end and the rotating shaft 2, and fulcrum structure is a fixing quarter butt 8 in rotating shaft 2, quarter butt is towards being toward inboard, quarter butt 8 end in addition just becomes fulcrum, is movably hinged with bearing pin with damper rod 4 other ends, is with torsion spring 5 in the rotating shaft 2 simultaneously, torsion spring 5 one ends are fixed in the rotating shaft 2, and the other end is fixed on the cushion frame 7.Whole damper rod 4 can be hidden in the seat cushion inner chamber, reaches the neat appearance purpose.
Its operation principle is such, as Fig. 3,4, when spectators take a seat, apply external force to seat cushion 1 seat cushion is put to flat condition from the state of standing up, this moment, seat cushion 12 rotated around the shaft, made torsion spring 5 turn over an angle and came accumulation of energy, unidirectional damping bar 4 is in piston rod 10 pressurized indentation states simultaneously, check valve 14 is opened on the piston, and liquid 12 is freely entered, so spectators can open and set level seat cushion 1 easily; Working as spectators on the contrary rises immediately, external force is cancelled, the restoring force of torsion spring 5 is packed up seat cushion, and unidirectional damping bar 4 is in piston rod tension elongation state at this moment, and check valve 14 is closed on the piston, and liquid can only be gone out by throttling pore 13, so unidirectional damping works, seat cushion 12 rotates and stands up around the shaft lentamente, goes to the state of standing up from setting level state, thereby realizes slow purpose of standing up.
