In order to solve deficiency in the prior art, the purpose of this utility model is to provide a kind of telescopic buses to help
Hand.The bus handrail is power using the wind spring being arranged on rolling wheel, by wind spring and nylon band connection, opens length adjustment
It switchs and pulls down, wind spring energy storage by volume power, when external force revocation, wind spring releases energy return, to complete telescopic, solves
Because grasping difficult problem caused by height factor.
To achieve the goals above, the utility model use the specific scheme is that
A kind of telescopic bus handrail, it is characterised in that: including shell；The shell includes hand-held part and stretches
Portion sets scalable component in the pars contractilis；The scalable component includes reel, wind spring, nylon tape and length adjustment switch；
The reel center is equipped with shaft, inner ring one end connection of the shaft and wind spring；The wind spring volume is located on reel；The Buddhist nun
Tengential belt includes the portion of stretching and the curled portion that volume is located on wind spring, and the free end for stretching portion passes through the access way on shell simultaneously
It is fixed on the cross bar on bus by a fixator, the free end of the curled portion is connect with wind spring；The length adjustment
It switchs the arc wheel shell being arranged by abutting casing circumference inner wall and the switch button being arranged on wheel shell forms, the one of the wheel shell
It holds close to access way；Switch hole is additionally provided on the shell, the switch button is exposed to outside shell by switch hole and energy
It pushes to or pushes down to realize along switch hole flexible or fixed.
It is advanced optimized as to above scheme, the shell is cake type structure, by two identical half shells pair
Connect composition；The pars contractilis is located at the upper half of shell, and the handgrip part is in the lower half of shell.
It is advanced optimized as to above scheme, the nylon tape portion of stretching is equipped with maximum height limiter, prevents
Nylon tape excess shrinkage under wind spring effect.
The utility model has the advantages that
A kind of telescopic bus handrail described in the utility model, structure is simple, and it is convenient to stretch, and sets wind spring using interior
Energy variation realize intensified nylon band length adjustment.When switch button pushes down, the wheel shell of length adjustment switch sticks into close
In the gap between rolling wheel and outer casing inner wall at access way, rolling wheel is locked, length is fixed, when needed, by switch button
It above pushes away, unlocks, lower pulling force is applied by hand-held part, the release of nylon tape curled portion increases length, while rolling wheel rotates, wind spring
Compression energy storage, when nylon tape is discharged to appropriate length, the locking of pushdown switch button terminates in use, upper buck switch button solution
Lock, wind spring release energy, and nylon tape is driven to be contracted to normal length, in order to avoid nylon tape contraction is exaggerated, stretch portion in nylon tape
Equipped with maximum height limiter.Using the bus handrail, the grasping of different height passengers can satisfy, improve comfortable by bus
Degree, preferably advocates Green Travel.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Embodiment 1
A kind of telescopic bus handrail, as shown in Figs 1-4, including shell 1；The shell 1 is cake type structure, by
The two identical docking of half shell 101 compositions；The shell 1 includes positioned at the hand-held part 104 of lower half and positioned at the upper half, envelope
It closes and hollow pars contractilis 103, sets scalable component in the pars contractilis 103；The scalable component includes reel 2, wind spring
3, nylon tape 4 and length adjustment switch；2 center of reel is equipped with shaft 201, inner ring one end of the shaft 201 and wind spring 3
Connection；The wind spring volume 3 is located on reel 2；The nylon tape 4 includes stretching portion and curled portion, the free end for stretching portion
Access way 102 on shell 1 is simultaneously fixed on the cross bar on bus by a fixator 7, the curled portion from
It is connect by end with wind spring 3 and curled portion volume is located on wind spring 3；The length adjustment switch is by 1 circumferential inner wall of abutting shell
The arc wheel shell 5 of setting and the switch button 6 being arranged on wheel shell 5 form, and one end of the wheel shell 5 is close to access way 102；
Be additionally provided with switch hole on the shell 1, the switch button 6 by switch hole be exposed to shell it is outer and can be pushed to along switch hole or
It pushes down to realize flexible or fixed.
The diameter of the public security vehicle handrail, shell 1 is 140mm, with a thickness of 30mm.
In said structure, 103 hollow structure inside of pars contractilis is semicircle, and reel 2 can do rotation fortune in the space
Dynamic, the foreign steamer maximum gauge of reel 2 is slightly less than the radius of shell 1, and when length adjustment switch locking, one end of wheel shell 5 can block
Into in the gap between 1 inner wall of reel 2 and shell, because nylon tape volume 4 are located at outside reel 2, the compressible locked nylon tape of wheel shell 5
4, reel 2 stops rotating, and realizes and fixes.
4 portion of stretching of nylon tape is equipped with maximum height limiter 8, prevents nylon tape 4 from excessively receiving under wind spring effect
Contracting.
