Abstract
The utility model relates to a linkage angle controller for a herring bone ladder. The adopted technical scheme is as follows: a linkage pull rod for connecting two herring bone ladder angle control sheets is arranged in the middle of a movable hinge of the two herring bone ladder angle control sheets for replacement, holes are formed at the two ends of the linkage pull rod, after the two ends of the linkage pull rod penetrate through the holes of the angle control sheets, the two ends are fixed by split pins, and the linkage of the two herring bone ladder angle control sheets can be realized by pulling the linkage pull rod up. The linkage angle controller has the beneficial effects of convenience in use and easiness in implementation.
Description
Technical field
The utility model relates to the apparatus of ascending a height, especially a kind of double ladder interlock angle controller.
Background technology
In prior art, double ladder is to apply very general instrument, to both sides slip cause danger, is provided with the angle control strip in order to prevent double ladder, and the angle control strip is all one on one side, when drawing in, double ladder must to twice gathering of angle control strip, operate respectively, and very inconvenient.
Summary of the invention
The purpose of this utility model just is to provide a kind of the double ladder interlock angle controller that need once the angle control strip can be drawn in.
The technical scheme that the utility model adopts is, in the middle of the hinges of two double ladder angle control strips, replacement is provided with the linkage pull rod that connects two double ladder angle control strips, the linkage pull rod two ends are porose, after the hole of angle control strip is passed at the two ends of linkage pull rod, two ends are fixed with cottor pin, upwards pulled two double ladder angle control strips of linkage pull rod can realize interlock.
The beneficial effects of the utility model are easy to use, easily implement.
