Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described.
Please refer to shown in Fig. 1 and Fig. 2, that show the concrete structure of the first embodiment of a kind of buffer device for shower room door of the present invention, comprise metal derby 10, cylinder 20, magnet ring 30 and piston 40, wherein:
Described metal derby 10 is fixed on door 1, described cylinder 20, magnet ring 30, piston 40 is all fixed on doorframe 2, the left end of this cylinder 20 offers a screwed hole, one left end gas flow modulation lid 50 is threaded by the left end of this screwed hole with cylinder 20, and the screwed hole of cylinder 20 is sealed, for ensureing sealing, this left end gas flow modulation lid 50 cover has cushion rubber 51, the right-hand member of cylinder 20 also offers a screwed hole, one right-hand member gas flow modulation lid 60 is threaded with cylinder 20 right-hand member by the screwed hole of cylinder 20 right-hand member, right-hand member gas flow modulation lid 60 cover has cushion rubber 61, and the gas channel had between the screwed hole of right-hand member gas flow modulation lid 60 and cylinder 20 right-hand member for air circulation, described piston 40 is placed in the inner chamber 21 of cylinder 20, and the inner chamber 21 of cylinder 20 is divided into two sections, mutually isolated left and right, on piston 40, cover has cushion rubber 41, to ensure the sealing between two sections, the left and right that the inner chamber 21 of cylinder 20 is isolated by piston 40, 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 the present embodiment is as follows:
Shower house close the door 1 time, metal derby 10 moves to shower house doorframe 2 direction along with door 1, magnet ring 30 and metal derby 10 attract each other, now magnet ring 30 promotes piston 40 to left movement, the air of cylinder 20 inner chamber 21 left sections is compressed, produce resistance, hinder piston 40 and magnet ring 30 to left movement, and then control metal derby 10 by magnet ring 30, reduce the movement velocity of door 1, along with door 1 continues toward the motion of doorframe 2 direction, the air compressing of cylinder 20 inner chamber 21 left sections more and more, resistance is increasing, the rate of opposite house 1 is also increasing, until piston 40 moves to extreme position, now door 1 and doorframe 2 are fitted just, door 1 is closed.
Be pointed out that, close the door 1 time, the dynamics that staff acts on door 1 is different, door 1 kinetic momentum is also different, dynamics is larger, the motion momentum of door 1 is also larger, the speed that metal derby 10 drives piston 40 to move is just faster, the air compressing of cylinder 20 inner chamber 21 left sections is just stronger, the resistance produced is just larger, and then the speed-buffering that opposite house 1 moves is just faster, buffering dynamics is also thereupon larger, otherwise, when the dynamics on door 1 of acting on is less, buffering dynamics also can be less, therefore, door 1 close the door 1 time, no matter be firmly large or little, all can not draw backlash.
Please refer to shown in Fig. 3 and Fig. 4, that show the concrete structure of the second embodiment of a kind of buffer device for shower room door of the present invention, the present embodiment is on the architecture basics of the first embodiment above-mentioned, increase by an air bag 70, and the left end of cylinder 20 offers the guiding gutter 22 above a screwed hole being positioned at cylinder 20 left end, left section of this guiding gutter 22 and cylinder 20 inner chamber 21 is communicated with, air bag 70 is connected with guiding gutter 22 by conduit 80, the two ends of conduit 80 are respectively by connector 90 and air bag 70, guiding gutter 22 docks, for ensureing the sealing of conduit 80 and guiding gutter 22 junction, described conduit 80 is provided with groove on the end be connected with guiding gutter 22, groove is arranged with cushion rubber 81.The present embodiment is substantially identical with the operating principle of the first embodiment above-mentioned, difference is: because left section of cylinder 20 inner chamber 21 communicates with air bag 70, close the door 1 time piston 40 to left movement, by air to the compression of air bag 70 direction, air bag 70 is inflated, now generation one is stopped that piston 40 continues the resistance to left movement by air, and then ensure close the door 1 time opposite house 1 further buffering, until piston 40 moves to extreme position, now door 1 and doorframe 2 are fitted just, and door 1 is closed.Further, if close the door 1 dynamics larger, door 1 kinetic momentum is larger, and the aeration speed causing air bag 70 is faster, and resistance is larger, and the buffering dynamics of opposite house 1 is also just larger.
Buffer of the present invention can stressed according to door 1 after moment of inertia automatically adjust buffering dynamics, even if close the door, 1 is firmly excessive, also there will not be the phenomenon of door 1 resilience, and buffer can not to produce contact stressed with door 1, thus extend application life, improve buffering effect.
The above, it is only present pre-ferred embodiments, not technical scope of the present invention is imposed any restrictions, thus every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
