Description
Technical field
The present invention relates to telescopic corrals, more particularly to it is a kind of simple in construction, it is skillfully constructed, energy-conserving and environment-protective, stretches light
Multistage automatically retractable formula railing freely.
Background technology
Railing is widely used in front door of level crossing, road control entrance and factory and enterprise etc., is mainly used in blocking
The vehicle entered without permission and personnel are cut, the railing of different length is generally set according to the difference for intercepting section width, it is general
Property it is poor, and because existing railing is usually one-piece integrated structure, when balustrade length is longer, it is extremely inconvenient not only to store and transport,
And railing easily deforms during use, its normal use is influenceed, while railing folding and unfolding moment of torsion is big, therefore generally require to match somebody with somebody and prepare enough
Enough balancing weights and power, cause unnecessary energy waste.
The content of the invention
Main one kind that there is provided of the invention is simple in construction, is skillfully constructed, energy-conserving and environment-protective, stretching, easily multistage can
Automatic telescopic corrals, solve railing poor universality present in prior art, yielding, storing is difficult, and folding and unfolding moment of torsion is big,
Cause the technical problem of unnecessary energy waste etc..
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：A kind of multistage can stretch automatically
Contracting formula railing, including base tube and sliding plug the multi-stage expansion pipe in base tube, it is provided with the mesopore of the multi-stage expansion pipe
Can promote multi-stage expansion pipe extend to base tube front port it is outer and outside base tube front port flared flexible tracheae successively, stretch
One end of contracting tracheae is bound on the expansion end of multi-stage expansion pipe, and the other end extends to outside base tube rear port and is connected to suction and discharge
On source.Suction source of the gas to flexible tracheal strips inflate when, the flexible outside distending of tracheae simultaneously promotes multi-stage expansion pipe horizontally outward to deploy,
It can change multi-stage expansion pipe length of run according to requirements by adding and subtracting aeration quantity, be skillfully constructed during use, versatility
It is good；The tracheae that stretched during suction source of the gas air-breathing drives multi-stage expansion pipe to bounce back in base tube, and folding and unfolding is simple, and storing is convenient, stretches light
Freely, energy consumption is low, energy-conserving and environment-protective for pine.
Preferably, between the mating surface close to the base tube and multi-stage expansion pipe expansion end, and it is multistage close to composition
Some groups of axial direction external slideway and axial inner slide are correspondingly provided between the mating surface at the pipe fitting expansion end of telescoping tube, in corresponding axial direction
Rolled between external slideway and axial inner slide and be connected to several balls.By between the mating surface of base tube and multi-stage expansion pipe, it is more
Set axially inside and outside slideway clamping ball holding to roll connection between the pipe fitting mating surface of level telescoping tube, reduce multi-stage expansion pipe
Resistance of taxing, make its folding and unfolding smooth freely, and saved energy consumption.
The cross section of base tube and multi-stage expansion pipe can be circular, the shape such as polygon, as it is further preferred that the base tube and
Multi-stage expansion pipe is that cross section is square aluminium alloy extrusions, and axial external slideway and axial inner slide are correspondingly arranged at each surface
Middle part.Base tube made of aluminium alloy extrusions and multi-stage expansion pipe, there is the advantages that intensity is high, in light weight, wear-resisting；Cross section is side
During shape, it is easy to the laying of axially inside and outside slideway, improves the stability slided.
As it is further preferred that be arranged between the adjacent bottom surface of the base tube and multi-stage expansion pipe two groups of axial direction external slideway and
Axial inner slide.Two row's balls are set in bottom, can avoid producing play when sliding between the pipe fitting of multi-stage expansion pipe, improve fortune
Row stability.
As it is further preferred that the axial external slideway and axial inner slide, which are integral type, extends in base tube inner ring surface or pipe fitting
Arc track on inside and outside anchor ring, ball location-plate is folded between corresponding axial external slideway and axial inner slide, ball is embedding
On ball location-plate in corresponding ball positioning hole.Axially inside and outside slideway integral molding is in base tube inner ring surface or pipe fitting
On inside and outside anchor ring, processing and forming is simple；Ball location-plate prevents ball from deviating from, and ball can be made respectively in orbit.
As it is further preferred that base tube corresponding with the axial external slideway and axial inner slide or multi-stage expansion pipe expansion
End is equipped with annular end shrouding, and the outboard end of ball location-plate is connected on the medial surface of annular end shrouding.Annular end
Shrouding makes the end face of base tube and multi-stage expansion pipe keep sealing, not only makes outward appearance neat and artistic, while prevents again in foreign matter entrance
Portion hinders sliding for multi-stage expansion pipe.
As it is further preferred that the connection end relative with multi-stage expansion pipe expansion end is provided with loop seal base, annular envelope
The outer shroud of mouth base is extended outwardly to form baffle ring, and when multi-stage expansion pipe outwards deploys, the medial extremity of ball location-plate is connected to
On the medial surface of baffle ring, flexible tracheae is interspersed in the mesopore of loop seal base.Loop seal base is equally to prevent foreign matter
Sliding for multi-stage expansion pipe is hindered into inside, while also there is sliding guide effect.
As it is further preferred that provided with the backstop rubber that adjacent pipe sections can be prevented to deviate from the top surface of the pipe fitting and bottom surface
Block.Backstop block rubber ensures to keep being reliably connected between pipe fitting, avoids skidding off connecting pipe.
Preferably, with being packaged with leading section envelope on the multi-stage expansion pipe of flexible tracheae interworking expansion end port
Head, the base tube rearward end relative with multi-stage expansion pipe expansion end are provided with rearward end end socket, and the both ends of flexible tracheae are separately fixed at
On leading section end socket and rearward end end socket, and the air guide turned in multi-stage expansion pipe and suction source of the gas is provided with rearward end end socket
Hole.Forward and backward end cap ensures that multi-stage expansion pipe keeps reliable location in flexible tracheal strips, it is ensured that force direction and expansion direction
Unanimously.
Preferably, the base tube other end relative with described multi-stage expansion pipe expansion direction is provided with base.Base is easy to
Base tube and fixture or other power sources are connected.
Therefore, multistage automatically retractable formula railing of the invention tool has the advantage that：
Spherical guide is installed additional on 1, aluminium section bars, is made multi-stage expansion pipe keep rolling connection when sliding, is reduced resistance of taxing；Bottom
Two row's balls are installed in portion, can be avoided producing play when sliding between pipe fitting, be improved operation stability.
2, change balustrade length using the folding and unfolding of multi-stage expansion pipe, make balustrade length adjustable, and cost is low, and storing is convenient, lead to
It is good with property.
3, are pneumatically used as power source, and railing stretches free and relaxed, and energy consumption is low, energy-conserving and environment-protective.
