Description
Technical field
This utility model relates to a kind of Novel ladder.
Background technology
Ladder is wide variety of apparatus in a kind of fire-fighting and repairs profession, in order to ensure effectively to use height, existing
Ladder in technology is stretching structure mostly, ensures longer use length while ensureing portable performance.In actually used mistake
Cheng Zhong, in order to save muscle power, it is common that after being relied on wall by ladder, regulates telescoping mechanism, makes extension ladder from fixed ladder
In stretch out, it is achieved the expanding-contracting action of extension ladder.For proof strength, extension ladder generally uses aluminum alloy materials, has higher
Hardness, relies on ladder and carries out descending operation in cavity wall, it is easy in use scratch cavity wall or other support
Thing；Additionally, for also cannot be carried out scaling operation on shaggy wall, cause extension ladder to use inconvenience.
Utility model content
In order to make up the deficiencies in the prior art, this utility model provides a kind of simple in construction, good novel of using effect
Ladder.
This utility model is achieved by the following technical solution:
A kind of Novel ladder, including extension ladder 1, fixed ladder 2, telescopic adjustment pin 3 be arranged at two groups of extension ladder 1 top
Slide mechanism；Described extension ladder 1 is fixed on the slide rail 21 of fixed ladder 2 by chute, and described chute and slide rail 21 are provided with
Length-adjustment holes, described telescopic adjustment pin 3 is movably arranged in the length-adjustment holes of fixed ladder 2 and extension ladder 1；Described skate machine
Structure includes the pulley 5 of pulley base 4 and two linear array；Described pulley 5 is fixed on the top of pulley base 4, institute by wheel shaft 51
The bottom stating pulley base 4 is provided with slot 41；The top of extension ladder is provided with the mounting groove coordinated with slot 41；Pulley base 4 leads to
Cross in the mounting groove that slot 41 is installed on extension ladder 1 top.
Preferably, described slot 41 being provided with through hole 43, bolt is placed through on the mounting groove sidewall at extension ladder 1 top
Fixing hole 13 and through hole 43 pulley base 4 activity is fixed on extension ladder 1.
Preferably, the described pulley base 4 position between two wheel shafts 51 is provided with reinforcing plate 42.
Preferably, the pedal of described fixed ladder and extension ladder is provided with rubber antiskid pad；The bottom peace of described fixed ladder 2
Equipped with insulation anti-skid rubber cushion.
Preferably, described pulley 5 includes metallic framework and the rubber wheel face being wrapped in around metallic framework.
The extension ladder provided in this utility model, by installing two groups of slide mechanisms on the top of ladder, can be by flexible
Ladder carries out stretched operation after resting on wall or furniture, due to the existence of slide mechanism, the telescopic process of extension ladder by
The sliding friction of ladder itself is changed into the rolling friction of roller, uses less strength to be pulled open by ladder, roller simultaneously
Also wall or chucking surface will not be caused damage, i.e. reduce labor intensity and protect again article and the ladder basis of dependence
Body；Ladder can also be overturn under traffic condition, tow on ground by rolling mechanism, or weight is positioned over ladder
Use as interim trailer on son；By further arranging reinforcing plate in pulley base, can further improve extension ladder
Intensity；By arranging rubber antiskid pad on pedal, steadiness during use can be improved；By pacifying in the bottom of fixed ladder
Dress insulation anti-skid rubber cushion, is ensureing while extension ladder stability, can effectively completely cut off and the contacting of ground, reduce contact
Risk.
Accompanying drawing explanation
Fig. 1 is the structural representation of extension ladder in this utility model；
Fig. 2 is the structural scheme of mechanism of slide mechanism in this utility model.
