Abstract
A kind of deceleration strip that height is variable, including utricule, the utricule is that a cross section is Oval strips shape seal, hydraulic oil is injected in the utricule, a bridge plate is equipped in the utricule inner cavity, utricule inner cavity is separated into two chambers up and down by the bridge plate, the bridge plate is equipped with multiple uniformly distributed apertures, the utricule periphery is additionally provided with lug, the bridge plate is coated in the utricule by the lug, when vehicle compared with low velocity to pass through, deceleration strip is depressed, vehicle can smoothly pass, when rule-breaking vehicle high speed passes through, deceleration strip can then be squeezed height, force vehicle deceleration.
Description
Technical field
The present invention relates to road traffic facility technical fields, particularly relate to a kind of deceleration strip that height is variable.
Background technique
In order in the safe section of urban district or accident-prone road section or important driving, national regulation highway road junction,
The positions such as industrial and mining enterprises, school, Residential Quarter Entrance must be laid with the safety measures such as deceleration strip, and deceleration strip is for reducing vehicle
Running velocity traffic Special safety setting, and largely reduce each traffic road junction accident occur, play buffering
Deceleration purpose improves the safety at traffic road junction, but vehicle is in the deceleration strip Jing Guo the prior art, though running speed compared with
Slowly, it also still jolts, the vehicle for making traveling pass through at a slow speed is also greatly affected, with the driving requirement of very improper people.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of height can be changed deceleration strip, when vehicle with
When passing through compared with low velocity, deceleration strip is depressed, and vehicle can smoothly pass, and when rule-breaking vehicle high speed passes through, deceleration strip is then
It can be squeezed height, force vehicle deceleration.
The present invention is achieved by the following technical solutions.
A kind of deceleration strip that height is variable, including utricule, the utricule are that a cross section is that Oval strips shape is close
Feng Ti injects hydraulic oil in the utricule, is equipped with a bridge plate in the utricule inner cavity, the bridge plate is by utricule inner cavity
Two chambers up and down are separated into, the bridge plate is equipped with multiple uniformly distributed apertures, and the utricule periphery is additionally provided with lug, described
The bridge plate is coated in the utricule by lug.
Advanced optimizing technical solution is, the utricule epicoele wall thickness is greater than cavity of resorption wall thickness.
The present invention is provided with multiple apertures because using on bridge plate, by the combination of two chamber hydraulic oil above and below utricule, when
When the enforcement of vehicle low speed passes through, wheel rolls Cavity surface, and hydraulic oil flows into cavity of resorption by the aperture on bridge plate, and deceleration strip is pressed
Low, vehicle can smoothly pass, and when vehicle high-speed passes through, because the aperture on bridge plate plays the role of hydraulic damping, epicoele is hydraulic
Oil can not flow into cavity of resorption in a short time, so that epicoele is extruded and raised, vehicle deceleration be forced, after vehicle passes through, because upper
For cavity wall than cavity of resorption wall thickness, epicoele tension is greater than cavity of resorption tension, and the oil of cavity of resorption is retracted upper Cavity surface, has reached reasonable control vehicle
The beneficial effect of running velocity.
Detailed description of the invention
Fig. 1 is the main structure diagrammatic cross-section of the embodiment of the present invention.
Specific embodiment
It is described further below in conjunction with attached drawing and the embodiment of the present invention.
A kind of deceleration strip that height is variable, including utricule 1, the utricule 1 are that a cross section is Oval strips shape
Seal injects hydraulic oil 11 in the utricule 1, is equipped with a bridge plate 2 in 1 inner cavity of utricule, the bridge plate 2 will
1 inner cavity of utricule is separated into two chambers up and down, and the bridge plate 2 is equipped with multiple uniformly distributed apertures 21, and 1 periphery of utricule is also set
There is lug 12, the bridge plate 2 is coated in the utricule 1 by the lug 12.
Advanced optimizing technical solution is, the 1 epicoele wall thickness of utricule is greater than cavity of resorption wall thickness.
Built-in groove first is opened up in required section when use, then by holding of the embodiment of the present invention on pre-buried notch.
