Description
Technical field
Traffic safety protection field is the utility model is related to, especially a kind of fence of adjustable shielded area.
Background technology
The hollow metal safe fence used at present, construction are fixed, and it is some to substantially belong to two cross bar intermediate vertical arrangements
Protective plate, protective plate are fixed between cross bar, and the interval between protective plate is fixed, to being blocked in requisition for ventilation or needs
Zone of protection, free adjustment can not be realized.
Utility model content
The purpose of this utility model be to solve the problems, such as above-mentioned existing fence protective plate shielded area can not from main regulation,
Provide a kind of fence of adjustable shielded area.
Technical scheme is used by the utility model solves its technical problem：A kind of fence of adjustable shielded area,
Including：Column（1）, cross bar（2）And some protective sheets（3）, in addition to regulation handle（4）；The cross bar（2）Inside is provided with
First rotary shaft（21）, the first rotary shaft（21）Through column（1）Provided with regulation handle（4）；Each protective sheet（3）It is interior
Through there is the second rotary shaft（31）, the second rotary shaft（31）Top the second helical gear is installed（32）；First rotary shaft
（21）With each second helical gear（32）Corresponding position is provided with the first helical gear（22）；First helical gear（22）With
Two helical gears（32）Cooperating；Pass through regulation handle（4）Drive the first rotary shaft（21）Rotate, the first rotary shaft（21）On
First helical gear（22）Rotate upwardly and downwardly, drive the second rotary shaft（31）Left-right rotation, while protective sheet（3）Rotated also with second
Axle（31）Left-right rotation.
In the utility model, regulation handle（4）With the first rotary shaft（21）Connection, passes through regulation handle（4）Rotation up and down,
First helical gear（22）With the second helical gear（32）It is mutually twisted, the first helical gear（22）With the first rotary shaft（21）Turn up and down
It is dynamic, while the second helical gear（22）Drive the second rotary shaft（31）Left rotation and right rotation, while protective sheet（3）Also with the second rotary shaft
（31）Left-right rotation, now two root posts（1）Between shielded area also with become diminish greatly, work as protective sheet（3）Go to and horizontal stroke
Bar（2）When vertical, shielded area is minimum；Work as protective sheet（3）Go to and cross bar（2）When parallel, two root posts（1）Between protected
Piece（3）Block completely.
Preferably, the column（1）It is bolted on ground.
Preferably, first helical gear（22）With the second helical gear（32）Axis perpendicular, the first helical gear
（22）With the second helical gear（32）Gear motion.
Preferably, the protective sheet（3）On be pasted with reflecting strips.
The beneficial effects of the utility model：Rotated up and down by regulation handle, the helical gear phase of the different parts of two controls
Mutually occlusion, drive protective sheet using the second rotary shaft as axle center left-right rotation, now the shielded area between two root posts also with
Change diminish greatly, when protective sheet is gone to it is vertical with cross bar when, shielded area minimum；When protective sheet is gone to it is parallel with cross bar when, two
Blocked completely by protective sheet between column, thus can improve the universal of the fence, this flexible structure is changeable, need divulge information or
It is that the zone of protection that needs block is applicable.
