Abstract
Foldable single pole of base ladder be by the foot climb 1, upright rod 2 and base 3 constitute. The foot is climbed 1 and is included footboard 11, sliding lock 12 and antiskid rubber mat 13. The utility model discloses because the sliding lock that two feet were climbed does not crack, the upright rod does not have the draw -in groove, therefore firm safety, and the sliding lock is light nimble and the base adoption is foldable from top to bottom, constitutes three connecting rods in four groups by upright rod 2, leg 31 and pull rod 32. The fourth leg struts and draws in in receives transportation of foldable messenger and convenient to carry like opening of umbrella frame.
Description
Technical field
The utility model relates to one and to ascend a height utensil, is the collapsible single pole ladder of a kind of base specifically.
Background technology
Self-locking pin is climbed owing to vertically putting when using vertical, and is convenient to handrail, and the ability therefore carrying gravity strengthens, climbing people stands reliable, having lightweight, intensity advantages of higher, can, when without easy to use when wall face supporting, be the ideal tools of climbing especially.But owing to have employed three leg bases, this ladder is easily toppled over to the opening direction between bipod, and base is not folding, make troubles to transport and use, and sliding lock crack along its length, through up-and-down rod during use, crack and be stuck in the draw-in groove of up-and-down rod, although sliding lock is stuck in wherein can be static or slide up and down, easily stuck, slide up and down dumb.
Summary of the invention
In sum, the purpose of this utility model is to provide a kind of base collapsible single pole ladder.
The purpose of this utility model is realized by following technology:
The collapsible single pole ladder of a kind of base, climbed (1) by pin, up-and-down rod (2) and base (3) composition, it is characterized in that: described pin climbs each one of (1) left and right pin, by pedal (11), sliding lock (12) and antiskid glue cushion (13) composition, the cylindrical body that described sliding lock (12) is upper and lower opening all round closure, during use, two sliding locks all pass same up-and-down rod (2), a pedal (11) is in the top of sliding lock, a pedal (11) at sliding lock bottom, described up-and-down rod (2) is the cross section single pole identical with sliding lock (12), described base (3) is that four legs are collapsible, by up-and-down rod (2), leg (31), pull bar (32) and sliding sleeve (33) composition, up-and-down rod (2) and leg (31) are with hinged, leg (31) and pull bar (32) are with hinged, pull bar (32) can in the upper slip of up-and-down rod (2) by sliding sleeve (33), pull bar (32) and sliding sleeve (33) are with hinged, by up-and-down rod (2), leg (31) and pull bar (32) form four group of three connecting rod.
Principle: climbing of the present utility model make use of locking phenomenon in mechanics and leverage, by human body own wt, makes sliding lock be held on up-and-down rod, produce larger frictional force, thus make people be easy to climb; Gravity because pin bears when people lifts pin reduces, and button unclamps automatically.
Four legs are collapsible, are to utilize linkage principle.Several shaft-like objects are coupled together by certain mode, and there is articulated centre, is slidably connected.Them are made to strut by the action of setting or draw in the scope of setting.
Feature: the sliding lock that the utility model is climbed due to bipod does not crack, and up-and-down rod does not have draw-in groove, therefore secure, the upper and lower light and flexible of sliding lock and base adopt collapsible, give transport and carry to bring convenience.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-pin climbs 2-up-and-down rod 3-base 11-pedal 12-sliding lock 13 antiskid glue cushion 31-leg 32-pull bar 33-sliding sleeve.
Detailed description of the invention
The purpose of this utility model is realized by following technology:
Sliding lock (12) tubular, during use, two sliding locks all pass same up-and-down rod (2), a pedal (11) is in the top of sliding lock, and a pedal (11) at sliding lock bottom, when such people stands, can put at grade by bipod.
Base (3) is that four legs are collapsible, and its four leg struts and draws in opens receipts as umbrella frame, is form four group of three connecting rod by up-and-down rod, leg and pull bar.The distance that the length of each bar, hinged position, sliding sleeve slide, calculate or draw with experiment in advance, make it reach to strut and draw in the object of base.
