Description

Portable cat ladder of dismantling

Technical Field

The utility model relates to a construction technical field, in particular to portable cat ladder of dismantling.

Background

The ladder stand is frequently used in work and life, great convenience is brought to people due to the ladder stand, and people can go up to a high place from a low place to make up for the height of people. The ladder stand is generally divided into two types, namely a fixed type ladder stand and a movable type ladder stand, wherein the fixed type ladder stand is generally arranged on larger equipment and larger building structures. For ordinary people, the movable ladder stand is relatively familiar, is basically visible everywhere, has a plurality of styles, including folding, lifting and the like, but the folding and lifting degrees of the ladder stand are limited, and the ladder stand is still inconvenient in use, for example, a household ladder stand is more tense in living space, and a long ladder is placed more tense and uncoordinated; in addition, the personnel who need to fight each construction site, such as the finishers, the installers and the like, are inconvenient to carry the ladder, and the embarrassment that the ladder cannot be installed always occurs; in some cases, people need to go to a high place, but the height of a common ladder is limited, so that the use requirement cannot be met; especially, in the areas where certain fire fighting vehicles are difficult to enter, fire fighters cannot transport the elevator to a fire extinguishing site, fire rescue is seriously affected, and the ladder is particularly important if the ladder is convenient to carry and can be extended infinitely. Based on this, need carry out technical innovation to current cat ladder, develop a section portable's multi-functional cat ladder.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a portable cat ladder of dismantling to the application of each scene is realized to more convenient mode, satisfies all kinds of crowds' demand.

The utility model relates to a portable detachable ladder stand, which comprises a ladder stand unit, a clamp and a ladder stand connecting unit; the ladder climbing unit comprises an upper protrusion, a lower groove, two side supports and a middle step; the size of the hoop is matched with the size of the supports at the two sides of the ladder climbing unit; the ladder stand connecting unit comprises two metal pieces connected through a connecting piece, and two grooves are formed in the metal pieces.

Preferably, the upper protrusion and the lower groove of the ladder climbing unit are matched and spliced with each other.

Preferably, the clip is fastened by a screw.

Preferably, the two inner grooves of the ladder stand connecting unit are matched with the lower grooves of the ladder stand unit in size and distance, and two screw holes are respectively formed in two sides of the upper portion of the connecting piece.

Preferably, the ladder coupling unit comprises two metal pieces coupled by screw fastening.

Advantageous effects

The utility model discloses generally convert great large-size cat ladder into detachable construction with daily use, no matter carry or deposit all more convenient, as long as the cat ladder unit is enough in addition, can infinitely increase in theory, this also makes its applied scene more extensive, can satisfy the nimble demand of each unit such as family expenses, market, school, district, enterprise, building site, fire control, has very strong practical value.

Detailed Description

The invention will be further described with reference to the following figures and examples:

as shown in the figure, the utility model discloses a portable cat ladder of dismantling, including cat ladder unit 0, clamp 5, cat ladder hookup unit 7. The ladder climbing unit 0 comprises an upper protrusion 1, a lower groove 3, two side supports 2 and a middle step 4; the size of the hoop 5 is matched with the size of the supports 2 at two sides of the ladder climbing unit 0; the ladder coupling unit 7 comprises two metal pieces 9 connected by a connecting piece 6, inside which two recesses 10 are provided.

Preferably, the upper protrusion 1 and the lower groove 3 of the ladder stand unit 0 are matched with each other, so that the insertion connection can be realized.

Preferably, the clip 5 is fastened by screws.

Preferably, the two inner grooves 10 of the ladder stand coupling unit 7 and the two grooves 3 of the ladder stand unit 0 are matched and connected with each other in size and distance, and two screw holes 8 are respectively arranged on two sides of the upper part.

Preferably, the ladder coupling unit 7 is fastened by two metal pieces 9 by screws matching with the screw holes 8.

The utility model is practical as two combination modes as shown in figure 4 and figure 5, when the ladder stand can depend on the structure in the use place, the combination mode shown in figure 4 can be adopted, the upper protrusions 1 of a plurality of ladder stand units 0 are directly inserted into the lower grooves 3 according to the use height, the assembly of the ladder stand units 0 can be realized, and the ladder stand units 0 can be raised by infinite insertion theoretically; if the height is higher, when more cat ladder unit 0 need be pegged graft and assembled, available clamp 5 fastens the grafting position to factor of safety when improving the use. When there is no structure for the ladder stand to rest on, the two ladder stands can be supported by each other in the same way as the combination shown in fig. 4 by adopting the combination shown in fig. 5, and then the two ladder stands are connected with each other by using the ladder stand connecting unit 7 on the top. In addition, to further maintain safety, the lower portion may also be pulled by a string when the combination shown in FIG. 5 is used.

The novel portable detachable crawling ladder is a single crawling ladder which needs to be additionally supported by splicing the crawling ladders; when the inserted ladder stand units are more and the height of the ladder stand units is higher, in order to ensure safety, the inserted parts are fastened by using the hoops, so that the safety coefficient is enhanced; in certain conditions of use where a single ladder is not supportable, two ladder units may be coupled together by a ladder coupling unit to support each other.

Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, the present invention is described in detail with reference to the preferred embodiments, and those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
