Background

The existing car roof guard rail for the elevator is generally formed by processing steel materials such as angle steel, round pipes, square pipes or plate bending pieces and the like, and plays roles of protection, isolation and warning. Since the prior national standards do not provide clear requirements for the strength of the car roof guard rail, most car roof guard rails do not have good safety and reliability in order to control the cost. To prevent accidents, warning signs of "leaning guardrail danger" or "forbidden leaning guardrail" are typically added at prominent locations on the car roof guardrail. Because the newly desired point of application of force is at the top of the guardrail and the installed and secured position of the guardrail is generally at the bottom, the spatial misalignment causes the guardrail to distort. And the guardrail fixed point position generates a little skew upset, and the transmission can be with the amplification of tens of times of deformation to the guardrail top, through investigation at the end of investigation to current sedan-chair top rail guard in the market, finds that most sedan-chair top rail guard all can't satisfy.

For example, a "pull-out type car roof guard rail" disclosed in chinese patent literature has a publication number: CN106185559A, which discloses a guardrail comprises a left upper guardrail, a left lower guardrail, a rear upper guardrail, a rear lower guardrail, a right upper guardrail and a right lower guardrail; the upper left guardrail, the upper rear guardrail and the upper right guardrail comprise a transverse square tube and two vertical square tubes fixed at two ends of the transverse square tube, but the scheme is not enough for the rigidity of the side guardrail.
