Abstract
The utility model discloses a multifunctional ladder. Technique side includes multifunctional ladder, main ladder by half ladder on the left side, the right partly terraced herringbone structure of constituteing, half ladder on the left side is close to the top both sides and is fixed with the joint seat, half terraced top coupling on the right side is in the seat of joint, half ladder upper end on the left side corresponds joint seat top and sets up clamping screw, the fixed orifices that corresponds with clamping screw is seted up to half ladder upper end on the right side. When needs with word when ladder, with half ladder on the right side upwards the upset penetrate half ladder upper end on the right side with the clamping screw on half ladder on the left side again and fix through tighten nut in seting up the fixed orifices to parallel with half ladder on the left side. Because it is fixed that half terraced both ends will be controlled in the adoption of this kind of structure, very firm after the connection, there is not the problem of rupture. In addition, for traditional corner positioning mechanism connection, its structure is simpler, and manufacturing cost is lower. (B /)
Description
Technical field
The utility model relates to a kind of ladder, is specially a kind of multifunctional ladder.
Background technology
In daily life, people usually to climb to a higher point operation by ladder.Ladder in conventional art generally has two types, i.e. yi shaped ladder and double ladder.Yi shaped ladder structure is the simplest, use is flexible, and condition must support by body of wall; Double ladder itself has support function, can unsettledly use, and condition it could be kept on level land to balance.These two kinds of ladders in practice respectively possess some good points, but all must possess certain condition in use, or have supporting surface, or are erected on level land.In addition, these two kinds of ladders belong to two kinds of different structures, and its usage is different, cannot realize mutual substituting.
For the problems referred to above, open (bulletin) number is that the Chinese utility model patent of " 2632283 " discloses a kind of multipurpose ladder, this ladder arranges corner detent mechanism by the top of left and right half ladder at double ladder, realizes the mutual conversion of yi shaped ladder and double ladder.But the multifunctional ladder shortcoming of this structure is: 1, corner detent mechanism structure is very complicated, and cost of production is very high, market is difficult to accept; 2, because corner detent mechanism is arranged on the top of left and right half ladder, after converting yi shaped ladder to, require very high to the stressed support of corner detent mechanism, if insufficient strength, be easy to cause ladder to split off, cause user from the risk of falling from high altitude; 3, the ladder of this structure is not suitable for and steps on roof.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of structure multifunctional ladder simple, esy to use, safe and reliable.
For solving the problem, technical side of the present utility model comprises multifunctional ladder, primarily of the main ladder of the herringbone structure of a left side half ladder, right half ladder composition, it is characterized in that: a described left side half ladder is fixed with socket joint near both sides, top, the terraced top end shaft in the described right side half is connected in socket joint, arrange standing screw above the corresponding socket joint in terraced upper end, a described left side half, terraced upper end, the described right side half offers the fixing hole corresponding with standing screw.
Described multifunctional ladder, is characterized in that: terraced lower end, the described right side half is provided with hook.
Described multifunctional ladder, is characterized in that: described hook to be arranged on fixed head and to be dismountablely arranged on one group of adjustment hole that terraced lower end, the described right side half arranges.
Described multifunctional ladder, is characterized in that: a described left side half ladder, right half terraced two ends arrange Anti-slip cover.
Described multifunctional ladder, is characterized in that: a described left side half ladder is up-narrow and down-wide, and the described right side half ladder adapts with the upper width of left half ladder.
Multifunctional ladder of the present utility model, by on a left side, half ladder is fixed with socket joint near both sides, top, right half terraced top end shaft is connected in socket joint, and above the corresponding socket joint in terraced upper end, a left side half, arrange standing screw, right half terraced upper end offers the fixing hole corresponding with standing screw.When needs yi shaped ladder, the right side half ladder is upwards turn to parallel with a left side half ladder, then the standing screw on the ladder of a left side half is penetrated right half terraced upper end and offer in fixing hole and fixed by nut screwing clamping.Because this structure adopts, terraced for left and right half both ends are fixed, very firm after connection, there is not the problem fractureed.In addition, connect relative to traditional corner detent mechanism, its structure is simpler, and cost of production is lower.
In addition, suburban area or rural area private housing's top layer of founding a capital is not fixed stair and is gone directly, but gets on bamboo ladder, wooden ladder, the climbing of iron ladder, and these ladders all can not bend and not link up with, and carry extremely inconvenient, also cannot ensure safely.Hook, by arranging hook in terraced lower end, the right side half, when user climbs roof, can hang on roof on body of wall, prevent ladder from sliding by the utility model, ensures safety.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model, display people word state;
Fig. 2 is structural representation of the present utility model, shows a word state.
Detailed description of the invention
As shown in Figure 1-2, multifunctional ladder of the present utility model, the main ladder of the herringbone structure be made up of a left side half ladder 1, right half ladder 2, a described left side half ladder 1 is fixed with socket joint 3 near both sides, top, and described socket joint adopts terraced 1 upper end, a left side half of two metal sheet welding to be formed.Terraced 2 tops, the described right side half are coupling in socket joint 3 by connecting axle, and arrange standing screw 4 above the corresponding socket joint 3 in terraced 1 upper end, a described left side half, terraced 2 upper ends, the described right side half offer the fixing hole 5 corresponding with standing screw 4.
For optimizing such scheme further, terraced 2 lower ends, the described right side half are provided with hook 6.The preferred set-up mode of described hook 6 for be first welded on fixed head 7 by hook 6, and by the dismountable one group of adjustment hole 8 being arranged on the terraced 2 lower ends settings in the described right side half of screw, realizes the Height Adjustable of hook 6 in this way.
For optimizing such scheme further again, a described left side half ladder 1, right half terraced 2 two ends arrange Anti-slip cover 9.A described left side half ladder 1 is up-narrow and down-wide, and the described right side half ladder 2 adapts with the upper width of left half ladder 1.Ladder is placed more steady, improve safety.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection domain of the present utility model.
