The invention discloses an adjustable metro handle capable of being telescopically straightened and fixed through centrifugal force. The handle includes a housing, the top of the shell is movably connected with a fixing rope. A coil spring is fixedly connected to the middle of the shell, a rolling block is fixedly connected to the middle of the coil spring, a pull rope is fixedly connected to theouter side of the rolling block, a first spring is fixedly connected to the inner wall of the pull rope, a first ejector block sleeving the middle of the first spring is fixedly connected to the top of the first spring, tooth grooves are formed in the inner wall of the shell, and a second spring is fixedly connected to the rolling block. The invention discloses an adjustable subway handle capableof being telescopically straightened and fixed through centrifugal force. Through cooperative use of the clamping blocks and the tooth grooves, after the length of the pull rope is adjusted, the pullrope only needs to be pulled suddenly and quickly, the clamping blocks are thrown out through centrifugal force, the clamping blocks are clamped with the tooth grooves, and therefore the length of thepull rope is fixed, the effect of fixing the length of the pull rope is achieved, stress points are provided for passengers, and the passengers can stand stably and firmly.

    一种可伸缩变直且靠离心力固定的可调节地铁用拉手,包括壳体,所述壳体的顶部活动连接有固定绳,壳体的中部固定连接有盘簧,盘簧的中部固定连接有卷块,卷块的外侧固定连接有拉绳,拉绳的内壁固定连接有弹簧一,弹簧一的顶部固定连接有与弹簧一的中部套接的顶块一,壳体的内壁开设有齿牙槽,卷块的内壁固定连接有弹簧二。该可伸缩变直且靠离心力固定的可调节地铁用拉手,通过卡块与齿牙槽的配合使用,在使用本发明时,当调节好拉绳的长度后,只需要突然快速拉动拉绳,利用离心力将卡块甩出,时卡块与齿牙槽卡接,从而使拉绳长度固定,从而达到了固定拉绳长度的效果,为乘客提供受力点,方便乘客站稳扶牢。
