The invention discloses a stably-sealed air fork, and relates to the technical field of bicycle air forks. When a large pit is encountered, wheels firstly make contact with the bottom of the pit, then the inner pipe moves towards the outer pipe, but the piston assembly is installed on the outer pipe through the connecting rod piece, so that when the inner pipe moves towards the outer pipe, it is equivalent that the piston assembly moves in the direction of compressing air in a compression cavity, and a sealing plate moves reversely under the action of air pressure to extrude a sealing ring; the sealing ring is extruded and deformed backwards due to the frustum-shaped influence of the plug body, so that the sealing performance between the sealing ring and the inner pipe is increased along with the increase of the pressure intensity in the compression cavity, that is, the larger the pressure intensity is, the larger the effect of the sealing plate is, and the tighter the contact between the sealing ring and the pipe wall of the inner pipe is, namely, the better the air tightness is; the problem that a non-improved piston can not guarantee sealing when the air pressure reaches a high value possibly when the air pressure of the air fork is too high is solved.

    本发明公开了一种密封稳定的气叉,涉及自行车气叉技术领域。本发明在遭遇大坑时,车轮先接触坑底,然后内管向着外管移动,但活塞组件由连接杆件安装在外管上,使得内管在向着外管移动时,相当于活塞组件向着压缩压缩腔内空气的方向运动,在气压的作用下封板反向移动挤压密封圈,而密封圈因其受塞体的锥台状影响越往后越会受到挤压进而形变,使得密封圈与内管之间的密封性随着压缩腔内的压强增强而增加,即压强越大封板作用越大,密封圈与内管管壁之间接触的越紧密,也就是所谓的气密性越好,解决了气叉在过大的气压下,非改进的活塞可能无法在气压达到高值的瞬间保证密封的问题。
