Abstract
The utility model relates to a flexible spike which comprises a shell, an elastic object, a sealing ring and a spike body. The spike body is arranged in the shell in a sleeved mode, a sealing ring is installed between the shell and the spike body, the sealing ring is fixedly installed on the spike body and can vertically move along with the spike body, the elastic object is installed between the shell and the spike body, and the spike body can vertically move in the shell under the action of external force and through the elastic object. The spike body is an existing light-reflecting spike or a self-illuminating spike at the market.
Description
Technical field
The utility model discloses a kind of railway spike of flexible railway spike, particularly a kind of anti-shovel, belongs to road traffic control technical field.
Background technology
Being widely used of railway spike, the vehicle making can be distinguished the shunting sign of road in night running process, but existing railway spike function goes up owing to being fixedly mounted on face to face, affect traffic safety and be easy to and by heavy-duty car, damaged by pressure and shoveled by snow shoveling machine, lose very large.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of technical scheme of flexible railway spike, by it, can effectively be prevented the destruction of snow removing vehicle and be damaged by pressure by heavy-duty car.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of flexible railway spike, comprise shell, elasticity thing, sealing ring, road rivet nut, it is characterized in that described road rivet nut is sleeved in shell, elasticity thing is installed between road rivet nut and shell, and road rivet nut can move up and down in shell under the effect of external force and elasticity thing; Between road rivet nut and shell, sealing ring is installed, sealing ring is fixedly mounted in rivet nut and can moves up and down with road rivet nut, and said road rivet nut is existing reflector or self-lighting dog nail on market.
Described flexible railway spike, is characterized in that, between described shell and road rivet nut, elasticity thing is installed.
Described flexible railway spike, is characterized in that, between described shell and road rivet nut, sealing ring is installed.
Described flexible railway spike, is characterized in that described elasticity thing is Compress Spring or gas spring.
The utility model advantage and good effect are:
While using this flexible railway spike, not only can facilitate driver's steering vehicle in night running process, can distinguish the shunting sign of road, prevent heavy-duty car damage by pressure and also when running into snow removing vehicle work, the destruction that can effectively prevent snow removing vehicle.
Accompanying drawing explanation
Fig. 1 is the utility model structural diagrams intention.
Fig. 2 is the utility model top view schematic diagram.
Fig. 3-4 are embodiment of the present utility model.
In figure: 1-road rivet nut, 2-shell, 3-elasticity thing, 4-sealing ring.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described further:
As shown in Figure 1-2, this flexible railway spike, comprise rivet nut 1, shell 2, elasticity thing 3, sealing ring 4, wherein road rivet nut 1 is sleeved in shell 2, sealing ring 4 is installed between road rivet nut 1 and shell 2, sealing ring 4 is fixedly mounted in rivet nut 1 and can moves up and down with road rivet nut 1; Between road rivet nut 1 and shell 2, elasticity thing 3 is installed, and road rivet nut 1 can move up and down in shell 2 under the effect of external force and elasticity thing 3.
In the embodiment of Fig. 3-4: middle road rivet nut 1 is sleeved in shell 2; elasticity thing 3 (the present embodiment Elastic thing 3 is Compress Spring) is installed between road rivet nut 1 and shell 2; between road rivet nut 1 and shell 2, sealing ring 4 is installed; when blocking the way rivet nut 1 runs into external force (as doughnut) and is greater than the elastic force of elasticity thing 3; road rivet nut 1 is retracted to (as Fig. 3) in shell 2 at once downwards; protection road rivet nut 1 is not damaged; when external force disappears, road rivet nut 1 rises at once (as Fig. 4) and recovers former state under the elastic force effect of elasticity thing 3.
