Another preferred mode is: and (2) taking the centers of two similar points as the circle center and the chord length as the radius, and sequentially reversely making semi-circles, wherein the arc lines of the semi-circles surround the outer circumferential line of the cross section of the connecting part.

More specifically, the connecting surface of the tee joint or the four-way joint extends outwards to form a buffering part, and the outer wall of the buffering part is gradually tightened along the extending direction of the buffering part. The outer ends of the connecting ports of the tee joint and the cross joint are provided with buffer parts, and the outer walls of the tee joint and the cross joint are gradually tightened to be transited to the outer surfaces of the connected vertical rods or cross rods, so that no hard outer edge is exposed at the connecting part, and passengers are prevented from being injured when the passenger car is braked emergently or is shifted.

More specifically, be provided with on montant and the horizontal pole and hold the position, it is provided with along the montant or the radial protruding ripple with sunken of horizontal pole at place to hold the position surface. The height and the habit of the passenger are comprehensively considered, and the position of the hand-holding part is determined, so that the passenger can hold the armrest more comfortably and tightly.

More specifically, the vertical rods and the transverse rods are iron tubes, and a baking paint layer covers the vertical rods and the transverse rods; the tee joint and the cross joint are made of aluminum alloy materials, and the baking paint layers cover the tee joint and the cross joint.

The utility model discloses a scheme, the outer concave convex structure at montant and the horizontal pole connection position in the passenger train handrail and the three-way or the protruding structure of the indent of the face of being connected of cross mutually support, and coefficient of friction is very big, and the bolt fastening of reusing, the structure is more firm. The handrail is simple in structure and less in material consumption, and can effectively solve the problem that the passenger car handrail is loosened after being used for a long time and has abnormal sound.
