Specific embodiment

Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.

One kind can lengthen assembly type ladder, as described in Figure 1 include main terraced 7 and lengthened ladder 8；Lengthened ladder 8 may be mounted at main terraced 7 On, play the role of extending main terraced 7.Fig. 1 is level Four ladder structure, and lengthened ladder 8 can also be superimposed below lengthened ladder 8, is such as schemed It is Pyatyi ladder structure shown in 4.

Specifically see Fig. 2, main terraced 7 include a pair of of main frame 2 and the first mounting plate 1 for being fixed on 2 bottom of main frame, this reality Applying the first mounting plate 1 in example is bar shaped, and first mounting plate 1 is matched in each 2 bottom of main frame respectively, in order to easy to assembly, this Main frame 2 and the first mounting plate 1 are directlyed adopt and are welded and fixed in embodiment；Wherein, master is stretched out at the both ends of the first mounting plate 1 respectively Frame 2,1 upper end of the first mounting plate stretches out 2 occiput of main frame and bends downward to form hook 1a, in conjunction with Fig. 5, the first mounting plate 1 Lower end forms the first docking section 1b cooperated with lengthened ladder 8 after stretching out main frame 2, is fixed for connection on the first docking section 1b Screw rod 1d.First foot piece 3 is installed, number can be rationally arranged according to 2 length of main frame in the first foot piece 3 between main frame 2 It measures, 3 quantity of the first foot piece is three in the present embodiment；For the convenience of structural strength and materials, main frame 2 uses angle Steel, and be arranged to U-shaped structure and conveniently connect with lengthened ladder 8.

In conjunction with Fig. 2 and Fig. 5 it is found that it is waist that the first mounting hole 1c, the first mounting hole 1c is also distributed on the first mounting plate 1 Type realizes the fixation with wall for plugging bolt or setscrew；The position of first mounting hole 1c is preferably provided at The first docking section 1b of 2 position of main frame and lower end is stretched out in one mounting plate, 1 upper end.

In conjunction with Fig. 2, Fig. 3, lengthened ladder 8 includes a pair of of elongated frame 5 and the second mounting plate for being fixed on 5 bottom of elongated frame 6；Second foot piece 4 is equally set between elongated frame 5；Elongated frame 5 be similarly angle steel material and be arranged to it is U-shaped, it is not too long It spends shorter than main frame 2；Second foot piece 4 is in the quantity on elongated frame 5 less than the first foot piece 3 on main frame 2, this implementation One is only arranged in example and is located at 5 lower part of elongated frame, to facilitate the assembly on elongated frame 5 top and main frame 2.In conjunction with figure 2, Fig. 7 and Fig. 8 is it is found that spiral shell is respectively set in the first foot piece 3 on main frame 2 and 4 both ends of the second foot piece on elongated frame 5 Line head, and it is all made into round steel structure in order to facilitate processing, the both ends thread head of round steel is pierced by the inside of bracket and coupling nut, circle Steel ontology is then stuck on the inside of bracket.

Specifically see Fig. 3,6 lower end of the second mounting plate extends elongated frame 5 and forms the second docking section 6b, the second mounting plate The first oblique inner bending of 6 tops vertically bends again and is formed step section 6a, and step section 6a is fixed for Chong Die with the first docking section 1b； The consistency of thickness of the vertical range that is formed between step section 6a and the second mounting plate 6 and the first docking section 1b, when step section 6a with After first docking section 1b overlapping, so that the first docking section bottom surface 1b and 6 bottom surface of the second mounting plate flush.

The specific fit structure of step section 6a and the first docking section 1b are as shown in fig. 6, the first docking section 1b is stacked in step section Below 6a, the screw rod 1d on the first docking section 1b is then pierced by step section 6a and is fastened by nut, thus realize step section 6a with The fastening of first docking section 1b；The top step section 6a herein is preferably flushed at the top of elongated frame 5, with facilitate elongated frame 5 with The docking of main frame 2.From fig. 6 it can be seen that 5 top margin of elongated frame is together with the bottom lamination of main frame 2, and pass through spiral shell Screw bolt and nut fastens the two.

As shown in figure 4, second docking section 6b of upside lengthened ladder 8 and downside add when lengthened ladder 8 has more than two It is overlapped and is fixed by fastener between second mounting plate 6 of long ladder 8.Therefore it as shown in figure 3, is again provided on the second docking section 6b Screw rod also sets up the second mounting hole 6c in screw rod two sides, for wearing bolt or setscrew, realizes the fixation with wall.

Ladder installs as above, and there are three types of fixed forms when use: one, being hung on a wall hook 1a or other jails Gu place uses；Two, without using hook 1a, directly with the first mounting hole 1c and the second mounting hole 6c by ladder fixation, i.e., It can be used；Three, hook 1a is hung on a wall or other is securely local, then cooperate the first mounting hole 1c and the second mounting hole 6c will be terraced It is used after sub- fixation.

As shown in fig. 7, the main frame 2 and the first mounting plate 1 of two sides are stacked together on main terraced 7, by the first foot when vanning It steps on part 3 to be placed in the square orifice that main frame 2 and the first mounting plate 1 fence up, remaining fastener is placed in box 1 i.e. It can；As shown in figure 8, being the packing method of lengthened ladder 8, principle is similar with main terraced 7, since elongated frame 5 is shorter, elongated frame 5 The possible size of square orifice to fence up with the second mounting plate 6 is smaller, fails to lay down the second foot piece 4, can only place box 2 10 can Second foot piece 4 is placed on 1 side of the first mounting plate.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change It also should be regarded as the protection scope of the utility model into replacement.
