Abstract
The utility model relates to a multi-purpose combined ladder frame, which is formed by the connection of a combined ladder surface and ladder feet, wherein, the combined ladder surface is composed of a fitting box, a folding plate and an endstone frame; the ladder feet can be flexed and folded. Because a composite structure is used by the utility model, the utility model has the advantages of reasonable structure, convenient use, powerful functions, material saving and one object with multiple functions; the utility model not only can be used as a Y-shaped ladder and a single ladder, but also can be used as a stool, a single bed, a push-pull trolley and an endstone perforation frame.
Description
The utility model relates to a kind of ladder that has the telescopic folding device and can change the device of platform, particularly a kind of combined ladder frames of using more.
At present, existing ladder generally is to be made of tread, foot of ladder.The weak point of this class ladder is: can only be as double ladder or single ladder, and it is big, not easy to store to take up space; On the other hand, though the ladder that has has increased the foot of ladder stretching device, function singleness is used inconvenient.
In view of above situation, the purpose of this utility model provides a kind of double ladder and single ladder of both having can be used as, and can be used as the combined ladder frame of using of stool, single bed, push-and-pull vehicle and end stone punching frame again more.
The purpose of this utility model is to realize like this, should manyly constitute by combination tread, foot of ladder with combined ladder frame, described combination tread is made of accessory box, folded sheet and end stone framework, it is folding that folded sheet can be " Z " type, be connected with hook with tubular axis between accessory box and the end stone framework, deposit the belt wheel connecting pin in the accessory box, the belt wheel connecting pin can be connected and fixed the joint ladder, and accessory box, folded sheet and end stone framework are an integral body.Described foot of ladder is made of joint ladder and bracket groove, and the joint ladder may contract in the bracket groove, and saving terraced top has a nose, and there is a jack inboard, makes up between tread and the foot of ladder to be connected with the rectangle nut and bolt.
Between the joint ladder of above-mentioned many foot of ladders with combined ladder frame spring catch is arranged.
Above-mentioned many length that trails with the folded sheet of combined ladder frame equals the length of one-sided foot of ladder.
Above-mentioned many rectangle nut and bolts with combined ladder frame are to be made of real axis rectangle nut and bolt, empty axle rectangle nut and bolt and bolt sleeve.
Compared with the prior art, the utlity model has following advantage:
1. one-object-many-purposes has increased the function of ladder, has reduced the use of unnecessary facility.
2. reduce use labour intensity, strengthened effect.
3. rational in infrastructure, good looking appearance, economical with materials, the scope of application is wide.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a front view of the present utility model.
Fig. 2 is trolley structure figure.
Fig. 3 is the end stone frame construction drawing.
Fig. 4 is a rectangle nut and bolt structure chart.
Referring to Fig. 1～Fig. 3, the utility model is made of combination tread and foot of ladder.The combination tread is made up of accessory box 1, folded sheet 2 and end stone framework 3, it is folding that the folded sheet 2 that belt wheel connecting pin 4 is housed in the accessory box 1, is positioned at combination tread top can be " Z " type, a side that is positioned at the basifacial end stone framework 3 of combination ladder is connected with accessory box 1 one sides with tubular axis 5, and end stone framework 3 opposite sides have a hook 6 to articulate mutually with accessory box 1 opposite side.3 liang of upper lateral parts of end stone framework respectively have a button button 7, and set bolt 8 links to each other with bracing frame 9, has two to have the fixedly circle 11 of adjusting bolt 10 on the bracing frame 9, fixedly on 11 liang of side stands of circle a slide bolt 12 is arranged respectively; Foot of ladder is made of joint ladder 13 and bracket groove 14, has cross-arm 15 to connect between each group joint ladder, and saving terraced top has a nose 17, and the inboard has jack 18 can insert spring catch 19.Foot of ladder is connected with rectangle nut and bolt 16 between the tread with combination.
As shown in Figure 4, rectangle nut and bolt 16 is made of real axis rectangle bolt 20 and empty axle rectangle nut and bolt 21 and bolt sleeve 22.Part is that fixed object is used between real axis rectangle nut and bolt 20 and the empty axle rectangle nut and bolt 21.
When doing the stool use, the spring catch 19 that joint is terraced pulls out, and all joint ladders are contracted in the bracket groove 14, gets final product after fixing.
When making single ladder and using, unclamp the rectangle nut and bolt 16 of the terraced top of joint and combination tread junction, foot of ladder is moved to and make up the position that tread is connected side by side, fixedly rectangle nut and bolt 16 gets final product again.
When doing the single bed use, take off foot of ladder on one side, the another side foot of ladder is moved to and make up the position that tread is connected side by side, open and be the folding folded sheet 2 of " Z " type, tile to the foot of ladder surface, as bed surface, the joint ladder of the foot of ladder that takes off is dispersed into jack 18 that the nose 17 that will save ladder after single inserts another side foot of ladder joint ladder in vertical state is fixedly connected and gets final product as the cabinet base bracing frame.
When making trolley and using, take off foot of ladder, the joint ladder of foot of ladder is dispersed into single, be 90 ° of angles successively and be connected to form " U " type framework, be connected and fixed four pin bottom it, get final product with belt wheel connecting pin 4.
When doing the use of end stone punching frame, unclamp the hook 6 that end stone framework 3 is connected with accessory box 1, resupination framework makes it perpendicular with the combination tread, fixedly connected tubular axis 5, after adjusting punch position with button button 7 and set bolt 8, rig is fixed on fixedly on the circle 11 from beginning to end, can uses.
