The purpose of this utility model is to provide a kind of two-tube lifting handrails, to solve mentioned above in the background art ask Topic.

To achieve the above object, the utility model provides the following technical solutions:

A kind of two-tube lifting handrail, including panel, main body cover, two-tube ironware and button；The panel is fixed on main body The upper end of shell；The upper end sliding of the two-tube ironware is threaded through in main body cover, two-tube ironware and main body cover clearance fit； It is equipped with one on the main body cover and horizontally extends into internal button, is fixedly connected with spring on the inner end cylinder of button, The other end of spring is fixed by screws on main body cover, and gasket is equipped between screw and main body cover；The inner end of button It is set as cylinder, is fixed with convex block on the side wall of end, is provided on the corresponding two-tube ironware of the convex block for latched position Clamping block, several lock holes are offered on clamping block, lock hole and convex block cooperate, and convex block is fastened under the support of spring In lock hole；It is connected between adjacent lock hole by channel, and the inner end width of button is less than between adjacent lock hole Channel.

Further: the two sides of the main body cover are equipped with screw, and screw thread is connected on panel.

Further: the upper surface of the panel is set as arcwall face.

Further: the outside screw of the screw is covered with trim.

Compared with prior art, the utility model has the beneficial effects that the utility model passes through main body cover and two-tube iron Lock mode is adjusted using the button with spring in part, so that main body cover and two-tube ironware are reached along two-tube direction shift motion To handrail elevating function, height is freely adjusted, keeps lifting handrail more firm, more tends to ergonomics, bring more Comfortable usage experience.
