Description

Assembled folding stair for building that can install fast

Technical Field

The utility model relates to the technical field of construction stairs, in particular to an assembled folding stair for a building, which can be quickly installed.

Background

A folding ladder is a civil engineering article, assists workers to fall down on a construction site, is like a movable stair, is opened when being folded, is folded after being used up, and is convenient to transfer. The folding ladder is required to be firm and firm for working, is widely applied to various civil engineering and finishing engineering, and is popular among more people due to convenience and dual-purpose property.

The most ground that is located of current folding ladder, its bottom has the risk of skidding with ground during the use, can lead to the ladder to collapse and cause personnel's damage, and telescopic folding stair fixed effect is not good, and each layer of board can't be effectively fixed, has certain potential safety hazard.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects that a laminate of a folding stair in the prior art is poor in fixing effect, easy to slip depending on the bottom of a ladder and poor in safety, and provides an assembly type folding stair for a building, which can be quickly installed.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a but assembled folding stair for building of quick installation, includes the footboard case, the welding of footboard roof portion outside has the connecting rod, the welding of connecting rod tip has the sleeve pipe, the inside welding in sleeve pipe both ends has the spring, the welding of spring one end has the telescopic link, the welding of telescopic link upper surface has spacing post, and the inside welding in footboard case both sides has the deflector, and the welding in footboard case both sides has the mount pad, the inboard card of mount pad is equipped with the inserted bar.

Preferably, one end of the telescopic rod penetrates through and extends into one side of the sleeve, and a circular hole matched with the inserted rod is formed in the surface of the telescopic rod.

Preferably, the limiting column penetrates through and extends to the outer side of the top of the sleeve, and a waist-shaped hole matched with the limiting column is formed in the surface of the sleeve.

Preferably, the surface of the sleeve is provided with a mounting hole.

Preferably, jacks matched with the telescopic rods are formed in the two sides of the pedal box.

The utility model has the beneficial effects that:

this flexible stair pass through the top fixed installation of placing, effectively avoid the bottom to skid and lead to the stair to collapse, and each layer is laminated the board and all is carried out effective fixation and locking, and the security is higher.

Drawings

Fig. 1 is a schematic structural view of a rapidly-installable assembly type folding stair for construction according to the present invention;

fig. 2 is a partial cross-sectional structure diagram of a rapidly-installed assembly type folding stair for construction according to the present invention.

In the figure: 1. a pedal box; 2. a connecting rod; 3. a sleeve; 4. a spring; 5. a telescopic rod; 6. a limiting column; 7. a guide plate; 8. a mounting seat; 9. and (4) inserting the rod.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-2, a can install assembled folding stair for building fast, including pedal case 1, the welding of 1 top outside of pedal case has connecting rod 2, the welding of 2 tip of connecting rod has sleeve pipe 3, the inside welding in sleeve pipe 3 both ends has spring 4, the welding of 4 one ends of spring has telescopic link 5, the welding of 5 upper surfaces of telescopic link has spacing post 6, the inside welding in pedal case 1 both sides has deflector 7, the welding in pedal case 1 both sides has mount pad 8, the inboard card of mount pad 8 is equipped with inserted bar 9.

Inside 5 one end of telescopic link run through and extend to one side of sleeve pipe 3, its surface seted up with inserted bar 9 complex round hole, spacing post 6 runs through and extends to the top outside of sleeve pipe 3, sleeve pipe 3 surface seted up with spacing post 6 complex waist shape hole, sleeve pipe 3 surface seted up the mounting hole, 1 both sides of footboard case seted up with telescopic link 5 complex jack.

In this embodiment, this stair comprises a plurality of pedal case 1, when not using, the telescopic link 5 of the next pedal case 1 one side is inserted in the jack on the upper portion of the previous pedal case 1 both sides, effectively accomodate, in use, the mounting hole on the 3 surperficial installation holes of the sleeve pipe of the first pedal case 1 passes through expansion bolts and installs on the bottom surface of eminence, effectively fix whole stair, press the telescopic link 5 of the 3 tip of the sleeve pipe of the next pedal case 1 afterwards, make its shrink, the next pedal case 1 can drop downwards, telescopic link 5 falls to the jack of the preceding pedal case 1 both sides bottom of antedisplacement under the direction of deflector 7, automatic re-setting under the effect of spring 4, telescopic link 5 stretches out from the jack of the bottom of the previous pedal case 1 both sides, form the step form.
