Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, with specific embodiment, utility model is carried out clear, complete description below in conjunction with the accompanying drawings.
Embodiment 1
Multi-section telescopic ladder as illustrated in fig. 1 and 2, it includes multiple section of ladder 1 being slidably connected, described section of ladder 1 includes two the terraced pipe 1-1 being arranged on the left and right sides and connects the stull 1-2 of two described ladder pipe 1-1, described stull 1-2 is connected with the upper end of described ladder pipe 1-1, wherein, the terraced pipe 1-1 of upper section of ladder 102 above is plugged in the terraced pipe 1-1, the terraced pipe 1-1 of upper section of ladder 102 of the lower section of ladder 101 being positioned at lower section and the terraced pipe 1-1 matched in clearance of lower section of ladder 101.It is provided with plug 8 bottom described ladder pipe 1-1, make ladder pipe 1-1 bottom lock, plug 8 and the terraced pipe 1-1 matched in clearance of lower section of ladder 102, the terraced pipe 1-1 entirety so going up section of ladder 102 is equivalent to piston, upper section of ladder 102 is during declining, and air-flow is slowly discharged from the gap of two terraced pipe 1-1, plays cushioning effect, avoid the quick landing of section of ladder 102, cause damage.
In addition to the section of ladder 1 of top, in the stull 1-2 of each section of ladder 1, two ends, left and right are provided with locking device；Described ladder pipe 1-1 top is provided with joint 1-3, and described joint 1-3 is provided with the connecting portion 1-4 of straight tube-like, and described stull 1-2 two ends are connected with described joint 1-3 by described connecting portion 1-4, and locking device is positioned at described connecting portion 1-4.
Described locking device includes that being arranged on unlocking of described stull 1-2 side dials torsion 2-1, the alignment pin 2-2 being arranged in described stull 1-2 and press the stage clip 2-4 of described alignment pin 2-2, the bottom of described ladder pipe 1-1 is provided with and described hole, location 1-6 suitable for alignment pin 2-2, and described unblock is dialled torsion 2-1 and is connected with described alignment pin 2-2 by being arranged on the slotted eye 1-5 of stull 1-2 side.Wherein, the ladder upper end of pipe 1-1 and joint 1-3 are provided with the through hole for making alignment pin 2-2 pass.
Stage clip 2-4 is in compressive state, when the terraced pipe 1-1 of upper section of ladder 102 is drawn upwardly out, when the location hole 1-6 being positioned at this ladder pipe 1-1 bottom moves to the position of alignment pin 2-2, under the effect of stage clip 2-4, alignment pin 2-2 extend in the hole 1-6 of location, makes section of ladder 102 be fixed on this position.
The middle part of described alignment pin 2-2 is provided with draw-in groove 2-3, and described unblock is dialled torsion 2-1 and is connected with described alignment pin 2-2 by described draw-in groove 2-3.Under the position-limiting action of slotted eye 1-5, limit the stroke of the effect of alignment pin 2-2.When needing to make section of ladder retract, unblock toggle 2-1 is stirred in the inner side of section of ladder, makes alignment pin 2-2 extract out from the hole 1-6 of location, and under gravity, upper section of ladder 102 declines retraction automatically.
Owing to upper section of ladder suit is with in lower section of ladder, from the bottom to top, the terraced pipe diameter of section of ladder tapers into extension ladder.
