Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, be not this practicality
New practical range is confined to this.
As shown in Figures 1 to 6；A kind of extension ladder described in the present embodiment, includes multiple cleat stanchions 1, and each cleat stanchion 1 is hollow
Ladder pipe, two neighboring cleat stanchion 1 can mutually stretch fit with different calibers；The set that be sheathed on cleat stanchion 1 is also included
Cap 4 and it is sheathed on the attachment cap 3 of cap bag 4；The attachment cap 3 is connected with crosspiece 2；The attachment cap 3 is provided with for the company of regulation
Connect the adjustment unit of cap 3 and 4 elasticity of cap bag；Locking unit for lock two neighboring cleat stanchion 1 is also included.The present embodiment
Described extension ladder, by arranging multiple cleat stanchions 1, user can control the quantity of mutually sheathed cleat stanchion 1, such that it is able to select
It is combined into the cleat stanchion 1 of different length；Outside which, two neighboring cleat stanchion 1 can be locked by arranging cap bag 4, prevent cleat stanchion 1 from taking off
Fall；By the attachment cap 3 for being sheathed on cap bag 4 is arranged, and attachment cap 3 is connected with crosspiece 2, dismounting can be easy to；By arranging
Adjustment unit controlling the elasticity of attachment cap 3 and cap bag 4, so as to control the elasticity of cap bag 4 and cleat stanchion 1 further；Pass through
Locking unit is set and is prevented from 1 landing of two neighboring cleat stanchion.
A kind of extension ladder described in the present embodiment, the attachment cap 3 include fixed part 32 and movable part 31；The regulation
Unit includes the screwed hole located at the through hole of movable part 31 and located at fixed part 32.Specifically, when user needs the company of regulation
Connect cap 3 and cap bag 4 elasticity when, it is only necessary to screwed togather with screwed hole through after through hole with screw, you can with adjust attachment cap 3 with
