In the present embodiment, the safety barrier 10 further includes the reinforcement structure 400 and the smooth reflector element 500.Institute
It states reinforcement structure 400 and supports the smooth reflector element 500 to fixed.The smooth reflector element 500 is used for the indicator light
300 light issued are converged.Light can be pooled to the position of Relatively centralized by the setting of the smooth reflector element 500, so that
The safety barrier 10 issues more uniform, stronger light.
In one embodiment, light transmission is set between two reinforcement structures 400 adjacent in three reinforcement structures 400
Film.
In the present embodiment, described in the setting of the light transmission film can protect in three reinforcement structures 400
Indicator light 300.The use environment of the safety barrier 10 can be highway, construction site, traffic accident or crossroad etc.
Need the place of safety instruction.The light transmission film can prevent dust or sundries etc. from falling into the instruction in use
The surface of lamp 300.The light transmission film can effectively avoid the indicator light 300 from being damaged, or be covered by dust etc..
It in one embodiment, further include stretching structure 600.The center of 500 protruding parts of smooth reflector element is arranged
Stretching structure 600.In one embodiment, the roadblock main body 100 can also be arranged in the stretching structure 600.This implementation
In example, the setting of the stretching structure 600 enables the safety barrier 10 more easily to move.The specific lifting knot
The connection relationship of structure 600 and the smooth reflector element 500 can there are many, can be according to the design needs of those skilled in the art
It is selected.
In one embodiment, the top 101 and the bottom 102 are regular polygon.The setting of top 101 is positive
Polygon can make the safety barrier 10 have more regular shape, more beautiful and generous.The setting of bottom 102 is positive
Polygon can make the safety barrier 10 with bottom surface is more firm is bonded.In addition, the bottom 102 and the side
103 have certain inclination angle, and the light absorbing efficiency of the solar battery cell 200 can be improved.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The several embodiments of the application above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
The limitation to claim therefore cannot be interpreted as.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the concept of this application, various modifications and improvements can be made, these belong to the protection of the application
Range.Therefore, the scope of protection shall be subject to the appended claims for the application patent.
