Abstract
The invention discloses a kind of Pneumatic extension bar, and it belongs to traffic control apparatus field, its easy to operate loss for reducing pressed gas simple in construction.What the present invention was realized in, it includes inflator, fold tracheae, the fold tracheae is filled with the telescopic lever that a kind of light-wall pipe by more piece gradient-thickness assembles in its overcoat, also synchronously it is fully retracted when fold tracheae loses telescopic lever when pressed gas is fully retracted, the telescopic lever also synchronous full extension when fold tracheae is filled with pressed gas full extension.The design is applied to the place of device railing.
Description
Technical field
Relevant with traffic control apparatus, in particular to a kind of Pneumatic extension bar of the invention.
Background technology
Class balustrade device is the conventional facility for carrying out traffic control, is risen and fallen rod-type by the method for operation, collapsible etc. a variety of；
Patent No. CN2015102688044 entitled " inflatable stretch railing " design disclose it is a kind of using pressure gas source as
The lifeline of power, its action space that occupies little space is but very big, is power operation simplicity using pressure gas source, but its railing master
Body is a kind of colloid pleated tube, and when railing needs to extend charged pressure gas, the pressed gas in pipe is promoting railing axial
（Laterally）Also the radial dimension of railing is inevitably significantly extended while stretching so that railing seems very thick,
This aspect is repugnant to the eye more important is the excessive pressed gas for consuming inflator, causes unnecessary power consumption to increase,
Meanwhile it virtually can also influence the extension elongation of railing.
The content of the invention
The purpose of the present invention is to provide a kind of Pneumatic extension bar, and it can solve the problems, such as foregoing.
The content of technical solution of the present invention is as follows：It includes inflator, fold tracheae, and the fold tracheae is filled with its overcoat
The telescopic lever that a kind of light-wall pipe by more piece gradient-thickness assembles, it is fully retracted when fold tracheae loses pressed gas
When telescopic lever be also synchronously fully retracted, when fold tracheae is filled with pressed gas full extension telescopic lever also it is synchronous completely
Stretching, extension.
The beneficial effects of the invention are as follows：It limits the expansion diametrically of fold tracheae in former design and only allows pressure
Gas extends tracheae, saves the consumption of pressed gas, has expanded the interception space of tracheae.
Brief description of the drawings：
Fig. 1 is that the Pneumatic extension bar of the design stretches the gradual change schematic diagram of work from short to long.
In figure, 1 is inflator, and 2 be telescopic lever, and 3 be fold tracheae.
Embodiment：
Below in conjunction with the accompanying drawings to the design explanation for example.
As illustrated, the design includes inflator 1, fold tracheae 3, one end of fold tracheae 3, which is fitted into, stores pressure gas
On the inflator 1 of body, fold tracheae is that the good elastomeric material of telescopic resilience is processed, the fold knot of its tube wall when no pressure is filled with
Structure can shrink completely is in most short status, and when there is appropriate pressed gas to be filled with pipe, the pleated structure of tube wall then can part
Open or open completely, whole body also can thickening many while being elongated to the limit and reaching most long status；In fold tracheae
Overcoat is filled with a kind of telescopic lever, and telescopic lever is a kind of embedding by elastic card by the thin-wall high intensity pipe of more piece gradient-thickness
The tubulose composition assembled for an entirety is connect, it is such as the reception telescopic antenna that electronic product assembles, its both ends are matched
In the both ends of fold tracheae suit in place, the telescopic lever also phase companion when fold tracheal strips are filled with pressed gas full extension
Full extension is walked, is synchronously fully retracted when fold tracheae loses telescopic lever when pressed gas is fully retracted and also accompanied, due to
The caliber of telescopic lever is immutable, and the fold tracheae in it only will be stretched in the pressure for the gas that is under pressure towards axial direction
It is long, while synchronous drive telescopic lever extends, and can similarly drive telescopic lever to be fully retracted when losing pressure；The design limits
Make the expansion diametrically of the fold tracheae in former design and only allowed pressed gas to extend tracheae, save disappearing for pressed gas
Consumption, has also expanded the interception space of tracheae.
Claims (1)
1. a kind of Pneumatic extension bar, it includes inflator, fold tracheae, it is characterized in that the fold tracheae is filled with one kind in its overcoat
The telescopic lever assembled by the light-wall pipe of more piece gradient-thickness, stretched when fold tracheae is lost when pressed gas is fully retracted
Contracting pull bar is also synchronously fully retracted, and when fold tracheae is filled with pressed gas full extension, telescopic lever is also synchronous stretches completely
