Abstract
A potable ladder is composed of two push and pull expansion supporting poles formed by a pole plug sleeve and a cross supporting whose two ends are respectively corresponding with two poles whole connection, the corresponding pole is provided with a corresponding button clipping hole, a flexible clip button formed by the clip button and the clip button top is fixed in the button clipping hole, after the pole is pulled out, one end of the clip button extends to the pole cavity and pulls out the pole node block to position, pressing the other end of the clip button, and the top pushing spring is removed the block by the pole node extended form one end of the compressed clip button in the pole cavity, and then is pushed to retract back. The utility model has the advantages of simple carrying and storing and small occupation area.
Description
Technical field
The utility model relates to the ladder that uses in a kind of daily life.
Background technology
The ladder that ascend a height in daily life at present, main room uses all is monolithic constructions, carrying during use, moves inconvenience, deposits the not only inconvenience but also the side of occupation of land when on the shelf.
Summary of the invention
Carrying when the purpose of this utility model provides a kind of use, move conveniently, take the portable ladder that occupies a narrow space when depositing.
The novel portable ladder that provides of this use is made of the two telescopic cramp bar of push-and-pull, two ends whole stulls that connect of corresponding with each respectively two bars joint that are made of bar joint sleeve, each corresponding bar joint has corresponding card buttonhole, the elasticity card button that is made of card button and card button goring push spring is loaded in the card buttonhole, and bar joint pull stretches out back card button one end and stretches into the bar joint block location that will stretch out in the bar chamber.When depositing, push the card button other end, goring push spring and be compressed the card button and stretch into an end withdraws from, stretches out in the bar chamber bar joint and remove block and can push away the withdrawal position.
Two cramp bars of portable ladder are the sleeve telescopic structure, carry, the superimposed size of two cramp bar sleeves is little when depositing, and carry, move conveniently, deposit to take to occupy a narrow space.
Description of drawings
Fig. 1 is the structural representation of portable ladder.
The specific embodiment
Accompanying drawing is embodiment of the present utility model, describes in detail of the present utility model below in conjunction with accompanying drawing
The specific embodiment.
As shown in the figure, two cramp bars of portable ladder are the cramp bar that is connected the push-and-pull telescopic structure that constitutes by bar joint (1), (2), (3), (4), (5), (7), (9), (10), (15), (18) sleeve that aluminium alloy extrusions is made, and wall sliding friction cooperation is touched in the subsides of two tube couplings that sleeve connects.The two ends of the stull (6) of making by aluminium alloy extrusions, (8), (12), (16), (17) respectively with corresponding two bars joint close on that upper end bar wall is whole to be connected, each corresponding tube coupling of cramp bar has card buttonhole (14), and the elasticity card button that is made of card button (13) and card button goring push spring (11) is loaded in the card buttonhole.Bar joint pull stretches out back elasticity card button one end and stretches in bar the chamber in and extension bar to be saved the block location, by the compression elasticity card button other end stretch into that card in the bar chamber is turned round the end withdrawal, the bar joint that stretches out removes block and can push away withdrawal.Making the used aluminium alloy extrusions of portable ladder, can to use cross section be square, rectangle or circular aluminium alloy extrusions.
