Description

A kind of ladder

Technical field

The utility model relates to a kind of ladder used when installing pendent lamp, belongs to the optimisation technique of ladder.

Background technology

Existing ladder is yi word pattern or chevron shaped, the drawback of yi word pattern ladder is: need a strong point in use, as metope, when there is no the strong point, when pendent lamp being installed as entreated in a room or more changing the bulb, need in the operation of room intermediate vertical, yi word pattern ladder is just without ample scope for abilities.

The drawback of chevron shaped ladder is: a people is used alone in process, can rock, and the spacing of marking time of ladder is fixed, stand on the marking time of chevron shaped ladder, often often can there is distance mounted lamp position at installation pendent lamp or more change the bulb excessive or apart from too small, cause the arm of installation personnel to can't reach bulb installation site, and people stand in a high position for ladder, chevron shaped ladder can shake, and is unfavorable for fitting operation; Meanwhile, when chevron shaped ladder uses, ladder is fully opened, and needs to take larger space and just can open ladder.

Therefore, need to find one at installation pendent lamp or when more changing the bulb, can effectively prevent ladder from rocking and not need the strong point, pendent lamp or the way more changed the bulb be installed in little being exclusively used in that take up room.

Summary of the invention

The purpose of this utility model is: provide a kind of and can effectively prevent ladder from rocking when installing pendent lamp or more changing the bulb and not need the strong point, and pendent lamp or the ladder more changed the bulb are installed in little being exclusively used in that take up room.

The technical solution of the utility model: a kind of ladder, the central post 2 identical primarily of balance base 1, multi-segment structure and foot rest 3, seat 4 and handrail 5 form; Foot rest 3 is fixed on the outer wall of central post, and foot rest 3 is vertical with central post, and every section of central post is provided with polylith foot rest from bottom to top; The top center of described balance base is provided with locating hole 11, on balance base roof, upwardly positioning seat 6 is provided with along locating hole 11, positioning seat 6 is provided with from top to bottom and forms the nested locating slot 61 of negative and positive with foot rest, after one section of central post is inserted locating hole from top to bottom, one piece on this section of central post fan-shaped foot rest 3 just snaps in locating slot 61, and central post can not be rotated under the effect of external force; Seat, top is inserted on the center capital of the superiors from top to bottom, and handrail to be fixed on seat, top and higher than seat, top.

Be provided with the reference column 21 that diameter is less than central post top diameter of bore bottom described central post, the endoporus enabling the reference column of the central post being arranged in top insert the central post top being positioned at below from top to bottom forms tight fit.

Described handrail 5 is connected with the bottom at seat 4 by a spreader.

The top of described handrail 5 is the U-shaped structure of opening upwards.

Handrail 5 is provided with hook for hanging tool bag.

Described central post 2 adopts the steel of high strength.

Described balance base 1 adopts the larger stone material of density proportion or mud builds part or iron plate is made.

Beneficial effect:

When 1, using ladder, hand catches the foot rest of top, and pin is stepped on foot rest and upwards climbed, and is sitting on seat, ladder top, and get a grip on the rail balance health on the other hand, and another hand is installed the parts of pendent lamp or more changed the bulb;

2, the instrument used will be needed to hang on the hook on handrail, take when conveniently working on ladder.

Detailed description of the invention

As shown in Fig. 1 to Fig. 6, a kind of ladder, the central post 2 identical primarily of balance base 1, multi-segment structure and foot rest 3, seat, top 4 and handrail 5 form; Foot rest 3 is fixed on the outer wall of central post, and foot rest 3 is vertical with central post, and every section of central post is provided with polylith foot rest from bottom to top; The top center of described balance base is provided with locating hole 11, on balance base roof, upwardly positioning seat 6 is provided with along locating hole 11, positioning seat 6 is provided with from top to bottom and forms the nested locating slot 61 of negative and positive with foot rest, after one section of central post is inserted locating hole from top to bottom, one piece on this section of central post fan-shaped foot rest 3 just snaps in locating slot 61, and central post can not be rotated under the effect of external force; Seat, top is inserted on the center capital of the superiors from top to bottom, and handrail to be fixed on seat, top and higher than seat, top.

Hand catches the foot rest of top, and pin is stepped on foot rest and upwards climbed, and foot rest be that spiral dislocation is risen on central post, can not encounter head when protecting user upwards to climb; Be sitting on seat, ladder top, get a grip on the rail balance health on the other hand, and another hand is installed the parts of pendent lamp or more changed the bulb.

Be provided with the reference column 21 that diameter is less than central post top diameter of bore bottom described central post, the endoporus enabling the reference column of the central post being arranged in top insert the central post top being positioned at below from top to bottom forms tight fit.Reference column is provided with draw-in groove, suits with the clamp of lower central column top endoporus, under external force, be tightly engaged, can not rotate.

Described handrail 5 is connected with the bottom at seat 4 by a spreader, and when needs bimanualness mounted lamp, can lean against handrail balance health, both hands complete installation work together.

The top of described handrail 5 is the U-shaped structure of opening upwards, and U-shaped structure is convenient to be grasped on ladder, when needing, also instrument can be hung in U-shaped structure, use as hook.

Handrail 5 is provided with hook for hanging tool bag, the instrument used will be needed to hang on the hook on handrail, take when conveniently working on ladder.

Described central post 2 adopts the steel of high strength.

Described balance base 1 adopts the larger stone material of density proportion or mud builds part or iron plate is made, and the heavy material of density, by the center of gravity close proximity to ground of ladder, can not rock when use ladder, when people works on ladder, can keep the balance and stability of ladder.

Ladder of the present utility model, when not using, a sectionly can be taken apart to be accommodated in a chest and carry out keeping; During use, take out from chest, can length rapid-assembling on demand; During ladder of the present utility model uses, area occupied is little, can meet and install pendent lamp or the demand more changed the bulb.

Above-described embodiment is only used to interpretation purposes of the present invention, and is not limitation of the present invention, those skilled in the art, in essential scope of the present invention, makes a variety of changes or substitutes, also should belong to protection category of the present invention.
