Description
Technical field
The utility model relates to a kind of ladder, specifically is three foot of ladders of the rotatable adjusting of a kind of terraced tread.
Background technology
Ladder is a kind of common instrument in life staying idle at home and the engineering construction.But existing double ladder is through the hinged herringbone structure that constitutes folding in upper end by two single ladders.The double ladder less stable.Existing three foot of ladders have remedied the shortcoming of double ladder less stable, but the terraced tread of three foot of ladders fixes, and when another side is climbed, move adjustment like needs again again, and it is convenient to use underaction; Also have a kind of three foot of ladders, three faces all to be provided with ladder and step on, materials are many, and cost is high, and are relatively heavier, move inconvenient.
The utility model content
The purpose of the utility model is the deficiency to prior art, and a kind of three foot of ladders of the rotatable adjusting of terraced tread of light, good stability are provided.
The technical scheme that realizes the utility model purpose is:
Rotatable three foot of ladders of a kind of terraced tread; Comprise that table top, ladder step on and three pillars, the upper end of said pillar is connected with the bottom surface of table top and is the pyrometric cone bodily form, it is characterized in that: first pillar is movable to be arranged in the circular sleeve; Be respectively equipped with a plurality of bayonet sockets on second, third pillar; The end that ladder is stepped on is fixedly connected with the outer circular sleeve of first pillar, and the bayonet socket coupling on the other end is provided with grab and is arranged on second, third pillar is connected, and all ladders are stepped on through connecting rod and are connected to one.
The lower end of said the first, the 3rd pillar connects through flexible connecting rod; One end of flexible connecting rod is provided with the lower end that tomfool's knot is fixed on the 3rd pillar, and the other end is provided with hook and is connected with the retainer ring at retainer ring that is arranged on the first pillar lower end or the 3rd pillar middle part; Said second, third pillar lower end connects through flexible connecting rod, and flexible connecting rod one end is provided with the lower end that tomfool's knot is fixed on second pillar, and the other end is provided with hook and is connected with the retainer ring at retainer ring that is arranged on the 3rd pillar lower end or second pillar middle part.
The upper end of said first, second pillar is fixedly connected with the bottom surface of table top, and the upper end of the 3rd pillar is provided with rotating bulb and is connected with the bottom surface of table top, is convenient to pillar and struts and draw in.
The bottom of said three pillars is provided with telescopic adjustment and adjustable diameter and screw adjusting structure, and the bottom of foot of ladder is provided with the non-slip rubber pad.
The middle part of said table top is connected through the hinge, and conveniently struts and draws in.
Rotatable three foot of ladders of a kind of terraced tread of the utility model; Main body is the pyrometric cone body structure of supported at three point; First pillar is provided with circular sleeve outward, and circular sleeve is rotatable, and is removable up and down; The end that ladder is stepped on is fixedly connected with circular sleeve, and the grab that each ladder is stepped on can snap into the ladder of another pillar and step on the bayonet socket.When needing the terraced tread of rotation adjustment, circular sleeve is up lifted about 5 centimeters, the grab that ladder is stepped on breaks away from bayonet socket, rotation again, and the grab that ladder is stepped on is stuck in another pillar ladder and steps on the bayonet socket and get final product.Through rotation adjusting ladder tread, can take turns to use the climbing function by two faces on three facades.After three foot of ladders strut, can the retainer ring of connecting rod hook from the pillar middle part that stretch be taken off on the retainer ring that is connected to corresponding pillar lower end, form the equilateral triangle face of ladder bottom, increase the stability of three foot of ladders.During use,, can adjust the telescopic adjustment structure or the adjustable diameter and screw adjusting structure of three column bottoms, make three foot of ladders more stable according to the actual conditions on ground.After using, connecting rod one end that will stretch takes off from retainer ring, is connected on the retainer ring at corresponding pillar middle part, table top and the 3rd pillar is received to terraced tread direction again, is convenient for carrying and collects.
The utility model is a kind of three foot of ladders of the rotatable adjusting of terraced tread of light, flexible, good stability.
