The principle of the telescopic structure is the use of a fixed length of the two sides of the triangle. That's the linkage mechanism. To connect several rod-shaped objects in a certain way, with hinge joints, sliding joints, etc. Make them move in the set range according to the set action. The skeleton of the umbrella is three connecting rods, A: the standing handle is one, B: on the umbrella with one, C: oblique support with one. A and B are hinged, B and C are hinged, C and A are hinged by A sleeve -- the sleeve slides over A, and the sleeve and C are hinged. The length of each rod, hinged position, sliding sleeve sliding distance, calculated in advance or obtained by test. Meet the requirements of opening and closing the umbrella. The umbrella rod is a telescopic hollow cylinder rod made of metal strip or plastic sheet. Its characteristic is that the metal strip or plastic sheet is preformed into a elastic crimped layer with memory function smaller than the outer diameter of the rod body, thus having self-tightening function, so that the crimped layer always has elastic potential energy to exert pressure on the telescopic rod.
