Referring to fig. 7 and 9, in the present application, an avoiding groove 25 is formed in the side surface of the supporting column 2, and the avoiding groove 25 is communicated with the mounting groove 22, so that the arc plate 324 can be exposed from the avoiding groove 25 to the supporting column 2 in the process that the arc plate 324 rotates eccentrically around the central axis of the rotating member 323, thereby reducing the possibility of interference between the arc plate 324 and the mounting groove 22 during rotation.
Referring to fig. 7 and 9, a second cover plate 26 is disposed at a notch of the avoiding groove 25, a bolt is mounted on the second cover plate 26, and the second cover plate 26 is fixed to the side surface of the supporting column 2 by the bolt and covers the avoiding groove 3221, so as to reduce the possibility that dust or solid garbage enters the mounting groove 22 from the avoiding groove 3221 after the handrail body 1 is mounted on the supporting column 2.
The implementation principle of the stair railing convenient to disassemble and assemble in the embodiment of the application is as follows:
when the armrest body 1 is installed, the handle 4 is inserted into the operation hole 231, the tooth-shaped portion 41 of the handle 4 is matched with the tooth-shaped groove 3231 of the rotating member 323, the handle 4 is rotated to enable the extending portion 3241 of the arc-shaped plate 324 to abut against the first limit stop 51, and at the moment, the limit portion completely enters the movable groove 24; after the slots 11 of the handrail body 1 are aligned with the supporting columns 2 one by one, the supporting columns 2 enter the corresponding slots 11; the handle 4 is rotated reversely to make the extending portion 3241 of the arc plate 324 abut against the second limit stop 52, at this time, the limit portion is generally exposed out of the movable groove 24, and the limit portion is matched and clamped with the limit groove 12 of the handrail body 1, so that the handrail body 1 is stably mounted on the support column 2.
When the temporary building reaches the service life and needs to be dismantled, the handle 4 is inserted into the operation hole 231, the tooth-shaped part 41 of the handle 4 is matched with the tooth-shaped groove 3231 of the rotating part 323, the handle 4 is rotated to enable the arc-shaped plate 324 to be propped against the first limit stop 51 again, and at the moment, the handrail body 1 can be conveniently dismantled from the supporting column 2; demolish the rag bolt who is fixed in fixing base 21 again, can detach the stair step with support column 2 to retrieve and recycle support column 2 and handrail body 1, can install support column 2 and handrail body 1 in the temporary building of newly-built, reduce the waste of resource and the production of construction waste, have energy-conserving, the effect of environmental protection.
The above is a preferred embodiment of the present application, and the scope of protection of the present application is not limited by the above, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
