Abstract

A multifunctional folding ladder is a ladder which is very convenient to carry, use, store and manage. The technical scheme is that 1, the ladder legs are composed of a plurality of foldable quadrangles, 2, an inner sleeve pipe assembly and an outer sleeve pipe assembly for herringbone ladder linking are arranged on the ladder, a clamping groove is formed in an outer sleeve pipe, a clamping tenon is arranged on the inner sleeve pipe, a notch for the clamping tenon to pass through is further formed in the outer sleeve pipe, 3, a T-shaped support assembly is arranged on the upper portion of the ladder, 4, a transverse Japanese-shaped support assembly is arranged on the lower portion of the ladder, 5, jack inserting columns for increasing the height are further arranged, and the like. The technical effects of the method are as follows: not only carry the use and deposit the management convenient, use also very nimble changeable, can single fan use, also can two combinations make chevron shape ladder use, two stacks can also increase different heights, four fans can also be the use of constituteing higher chevron shape ladder, and two chevron shape ladder stull upper berth panel are a good operation platform, unpack apart in order to prepare the reuse next time after the use, use changeable nimble, carry and deposit and all make things convenient for the hand.

Description

Multifunctional folding ladder

Technical Field

The invention belongs to the field of tool ladders for ascending, and particularly relates to a foldable ladder which is convenient to carry, store, combine and heighten and has multiple using functions.

Background

The ladder used by people at present is inconvenient to carry and store due to large volume, has single function, and is inconvenient for production and life and various activities of people.

Disclosure of the invention

The invention aims to solve the problems in the background art and provide a foldable ladder which is convenient to carry, store, use and manage and has multiple using functions.

The technical scheme adopted by the invention is as follows: the ladder leg is characterized in that the conventional upright column type ladder leg is changed into a ladder leg formed by combining a plurality of changeable quadrangles, an inner sleeve and an outer sleeve for herringbone ladder linking are arranged on the ladder, a T-shaped ladder support (a first support) and a transverse sun-shaped support (a second support) are further arranged, the first support and the second support mutually guarantee safety, the ladder has one function and can guarantee safety, the two functions are simultaneously effective, the ladder cannot be erected, the ladder is safe and reliable in use, and the inserting column and the inserting hole for increasing the height are further arranged on the ladder.

The invention has the following effects: the multifunctional chair is convenient for people to carry and store, can be used, can be adjusted in height at any time according to needs, and can be flexibly combined and used to form more functions.

For the purpose of explanation, further description is provided in conjunction with the accompanying drawings.

FIG. 1 of the drawings

Is an integral planning chart of a multifunctional folding ladder

1. Foldable ladder legs combined by a plurality of quadrangles, 2. combination of inner and outer sleeve pipes for herringbone ladder connection, see figure 2

3. T-shaped support assembly for supporting ladder, see figure 3 Ann

Horizontal day-shaped support assembly for 4-support ladder, see figure 4

5. The jacks for increasing the height, the two items of 5 and 28 in the attached figure 7 are the relations between the inserted posts and the jacks, and the two items are the relations between two fans, can be combined into a herringbone ladder for use, and can also be combined into a fan for use, (the combination of one fan is for increasing the height, see 27 in the attached figure 6)

FIG. 2 of the drawings

The figure is a partial view

6. The herringbone ladder is used after the inner sleeve is inserted into the outer sleeve and is rotated to a herringbone angle, and the clamping tenon enters the clamping groove at the moment.

FIG. 3 of the drawings

This figure is an illustration of a tee support for supporting the ladder.

Slide rail 13, slide rail 14, manual fixing bolt 15, manual fixing bolt hole 16 (without wire), nut 17 for fixing after folding the ladder, and relation of bolt and nut 22 in figure 4 for fixing after folding the ladder.

FIG. 4 shows a schematic representation of a drawing

The figure is a transverse Y-shaped support for supporting a ladder

18 hinges (two) 19 horizontal orange on ladder, 20 sliding bolt. 21 socket. Reference numeral 22 denotes a hand bolt for fixing the folded ladder, which is in a bolt-and-nut relationship with reference numeral 17 in fig. 3, and reference numeral 23 denotes a state in which the horizontal support is turned upside down by the hinge, and which is for fixing the folded ladder.

FIG. 5 shows a schematic representation of the structure

Is a schematic view of the folded ladder effect.

FIG. 6 shows a schematic representation of a drawing

Are illustrations of various uses of ladders.

24 single-fan use, 25 herringbone ladders use, 26 work bench building, 27 height increasing use method,

28 a plug post, 5 a plug hole with increased height, see figure 1, (28 and 5 in figure 1) is the relation of the plug post and the socket, and 29 is a nut for fixing two ladders for increasing the height. 30 is a fixing screw for increasing the height.

Instructions for use

The ladder can be used by manually loosening the fixing screws 22, pulling the ladder open by two hands, manually screwing the fixing screws 15, inserting the movable bolt 20 into the insertion holes 21, and the herringbone ladder can be used by spreading two (front and rear) ladders, inserting the inner sleeve into the outer sleeve through the notch 11 arranged on the outer sleeve, rotating the two ladders at an angle into a herringbone shape, and then folding the ladder by reverse operation (at the moment, the tenon can enter the clamping groove).

Fig. 7 refers to the drawings.
