The specific embodiment

Come the present invention is further described below in conjunction with accompanying drawing and specific embodiment.

Shown in please seeing figures.1.and.2, it has demonstrated the concrete structure of a kind of door of the present invention with first kind of embodiment of buffer, comprises metal derby 10, cylinder 20, magnet ring 30 and piston 40, wherein:

Said metal derby 10 is fixed on the door 1, and said cylinder 20, magnet ring 30, piston 40 all are fixed on the doorframe 2, and the left end of this cylinder 20 offers a screwed hole; One left end gas flow modulation lid 50 is threaded through the left end of this screwed hole with cylinder 20; And with the sealing of the screwed hole of cylinder 20, be to guarantee sealing, this left end gas flow modulation lid 50 is with cushion rubber 51; The right-hand member of cylinder 20 also offers a screwed hole; One right-hand member gas flow modulation lid, 60 screwed holes through cylinder 20 right-hand members are threaded with cylinder 20 right-hand members, and right-hand member gas flow modulation lid 60 is with cushion rubber 61, and have the gas channel that supplies circulation of air between the screwed hole of right-hand member gas flow modulation lid 60 and cylinder 20 right-hand members; Said piston 40 places the inner chamber 21 of cylinder 20; And with the inner chamber 21 of cylinder 20 be divided into mutual isolation about two sections; Be with cushion rubber 41 on the piston 40, with the inner chamber 21 that guarantees cylinder 20 by piston 40 isolate about sealing between two sections, magnet ring 30 is attached to the right side of piston 40; When door 1 is in closed condition, metal derby 10 is positioned at the lower left of piston 40.

The operating principle of present embodiment is following:

Shower house was closed the door 1 o'clock, and metal derby 10 is along with door 1 moves to shower house doorframe 2 directions, and magnet ring 30 attracts each other with metal derby 10, and this moment, magnet ring 30 promotion pistons 40 were to left movement; The air of cylinder 20 inner chambers 21 left side sections is compressed, and produces resistance, hinders piston 40 and magnet ring 30 to left movement; And then, reduce the movement velocity of door 1 through magnet ring 30 control metal derbies 10, along with door 1 continues toward the motion of doorframe 2 directions; Getting more and more of the air compression of cylinder 20 inner chambers 21 left side sections, resistance is increasing, and the speed influence of opposite house 1 is also increasing; Move to extreme position up to piston 40, this moment, door 1 was fitted with doorframe 2 just, and door 1 is closed.

Be pointed out that, closed the door that the dynamics that staff acts on the door 1 is different at 1 o'clock, door 1 kinetic momentum is also different; Dynamics is big more, and the motion momentum of door 1 is also just big more, and it is just faster that metal derby 10 drives the speed of piston 40 motions, and the air compression of cylinder 20 inner chambers 21 left side sections is just stronger; The resistance that produces is just bigger, and then the speed-buffering of opposite house 1 motion is just faster, and the buffering dynamics is also bigger thereupon, otherwise; Act on the dynamics of door on 1 hour, the buffering dynamics also can be less, therefore; Door 1 was being closed the door 1 o'clock, no matter firmly be greatly or little, can not draw backlash.
