The purpose of this utility model is the above-mentioned deficiency at prior art, adopt a kind of static nonfloating rail and mobile protect fence to be association of activity and inertia, have in quiet, moving outer have quiet way, and a kind of safe, efficient, handiness, long service life, road central strip movable rail that the effective vent width is big are provided.

The purpose of this utility model can be realized in the following way: a kind of road central strip movable rail, it is characterized in that movable rail comprises nonfloating rail and mobile protect fence, nonfloating rail is made and can be held mobile protect fence and make the hollow cavity structure that directed turnover is moved betwixt, mobile protect fence is fence movably, and at least two group rollers are installed on it; Two groups of rollers on the removable fence are respectively internal trolley and outer roller; The nonfloating rail inwall has the internal trolley that can allow on the removable fence successfully make the bearing surface that rolls back and forth therein, and its both sides, openend outer face are equipped with and are convenient to the limited roller that fence moves around betwixt and prevent the postive stop baffle that fence is deviate from the nonfloating rail cavity; Mobile protect fence is preferably movably fence composition of two product, the mutual joint of the removable fence of two product can be connected by a connecting bolt or other suitable common locksets, nut one side at connecting bolt has a tamper cover that nut is covered, and the fence below has ground, location pin can make mobile fence be fixed in predetermined guide position, ground.

Adopt good effect of the present utility model to be, operating personnel need not very firmly push-and-pull and just can or open rapidly the mobile fence reliably closing of two product, it is time saving and energy saving to operate, safe and reliable to operation, long service life, mobile protect fence shrinks the passage effective vent width of opening after nonfloating rail inside big, the road surface no longer stays any rigid barrier, can avoid effectively walking therebetween vehicle and the road junction guardrail wind up hang or with the accident of unexpected roadblock collision, thereby overcome the aforementioned deficiency that prior art exists.
