Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "front", "back", "left", "right", "up", "down", etc. are based on the directions or positional relationships shown in the drawings, and are only for convenience of description, but not for indicating or implying that the indicated device or element must have a specific direction, and be constructed and operated in a specific direction, and therefore, the present invention is not to be construed as being limited to the present invention.

Referring to fig. 1 to 4, the present invention provides the following technical solutions: an adjustable guardrail comprises a handrail rod 1, a connecting rod 2, a guardrail rod structure 3 and a support leg rod structure 4;

the foot bar structure 4 includes ground branch 41, hob 42 and rotatory piece 43, be equipped with connecting rod 2 between two ground branches 41, ground branch 41 is hollow form with

bar

1, 1 lower surface of bar is equipped with the through-hole, 41 upper ends of ground branch are equipped with spiral channel piece 411, hob 42 one end spiro union is in spiral channel piece 411, the hob 42 other end runs through bar 1's through-hole and links to each other with rotatory piece 43, the inside of bar 1 is located to rotatory piece 43, the thickness of rotatory piece 43 equals with bar 1's hollow thickness, guardrail structure 3 includes guardrail bar 31 and last guardrail bar 32 down, guardrail bar 31 locates connecting rod 2 upper surfaces down, go up guardrail bar 32 and locate 1 lower surface of bar, it cup joints and slides continuously with lower guardrail bar 31 to go up guardrail bar 32.
