Abstract

The utility model relates to rotating combined stairs. Joint pipes provided with stair treads, height adjustable rings and rubber gaskets are fixed on a central stand column; each joint pipe is hollowly sleeved on the central stand column with gaps left between each joint pipe and the central stand column; the rubber gaskets are filled on the joint pipes and filled in the gaps between the joint pipes and the central stand column, and are equipped with convex plates which are supporting against the joint pipes; the convex plates have same outer diameters with the height adjustable rings which are compressed tightly with the rubber gaskets; the supporting plate is welded and fixed on the other end of the stair tread on each joint pipe in a welding way; the supporting plates are provided with longitudinal rectangular holes and transverses rectangular holes to adjust the height and the width of the stair tread; handrails are fixed on the supporting plates with bolts; the lowest ends of the handrails support on the floor and the topmost ends of the handrails are respectively fixed to stair top rings with bolts ; one end of each stair top ring is fixed to the central stand column by using a bolt, and the other end of each stair top ring is fixed to the last handrail. The rotating combined stairs are detachable and can be installed on different sites, and the height and the width of adjacent stair pedals are all adjustable, thereby saving installation space.

Description

The rotation combined staircase

Technical field

The utility model relates to a kind of stair, particularly relate to a kind of detachable, can install at different scenes and the height and all adjustable rotation combined staircase of width of adjacent broadstep.

Background technology

As everyone knows, at present, the height of the broadstep of existing combined staircase and width all are fixing nonadjustable, can not regulate according to user's needs, and installing space are bigger, so its poor practicability.

Summary of the invention:

Main purpose of the present utility model be to overcome above deficiency and provide a kind of simple in structure, easy to use, detachable, can install at different scenes and the height and all adjustable rotation combined staircase of width of adjacent broadstep.

The technical scheme that its technical problem that solves the utility model adopts is: it comprises column, broadstep and railing, it is characterized in that: the pipe joint that fixedly has broadstep on the center stand column, height adjustable ring and colloid packing ring, the equal sky of each pipe joint is enclosed within on the center stand column, and leave the gap with center stand column, pipe joint all be plugged with the colloid packing ring up and down, have boss on the colloid packing ring, the external diameter of colloid packing ring just fills in pipe joint and center stand column leaves in the gap, boss withstands pipe joint, the external diameter of boss is identical with the external diameter of height adjustable ring, the colloid packing ring compresses with the height adjustable ring, the go upstairs other end of pedal of each pipe joint is welded with gripper shoe, have vertical slot and horizontal slot on the gripper shoe, use the bolt railing on gripper shoe, the least significant end of railing supports on the ground, top respectively successively with terraced apical ring bolt, one end and the center stand column bolt of ladder apical ring, the other end and last root railing are fixed.

The present invention can also adopt following technical scheme:

Described center stand column 1 is a hollow cylinder.

Described height adjustable ring 4 diameters are identical, its thickness difference.

One end of described broadstep 2 is an arc.

Advantage and the good effect that the utlity model has are: simple in structure, easy to use, detachable, can install at different scenes, and the height of adjacent broadstep and width are all adjustable, have saved installing space.

The specific embodiment

For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1-Fig. 5.

As Fig. 1-shown in Figure 2: the pipe joint 3 that fixedly has broadstep 2 on the hollow center column 1 of the present utility model, height adjustable ring 4 and colloid packing ring 5, each pipe joint 3 equal sky is enclosed within on the center stand column 1, pipe joint 3 is being with broadstep 2 to rotate on center stand column 1, pipe joint 3 leaves the gap with center stand column 1, pipe joint 3 all be plugged with colloid packing ring 5 up and down, have boss on the colloid packing ring 5, the external diameter of colloid packing ring 5 just fills in pipe joint 3 and center stand column 1 leaves in the gap, to increase frictional force, boss withstands pipe joint 3, the external diameter of colloid packing ring 5 is identical with the external diameter of height adjustable ring 4, the two ends of every Multi-joint hose 3 all are with colloid packing ring 5 and height adjustable ring 4, colloid packing ring 5 compresses with height adjustable ring 4, as shown in Figure 3-Figure 5: the go upstairs other end arc place of pedal 2 of each pipe joint 3 is welded with curved gripper shoe 6, have vertical slot 7 and horizontal slot 8 on the gripper shoe 6, they are used for regulating the height and the width of adjacent broadstep 2, simultaneously, after height adjustable ring 4 by different-thickness regulates the height of each broadstep 2, rotation pipe joint 3 is regulated the width of broadstep 2

The height of broadstep 2 and width are by after having vertical slot 7 and laterally slot 8 and height adjustable ring 4 whole adjustments finishing on the gripper shoe 6, promptly begin the location, pipe joint 3 bottoms and uppermost height adjustable ring 4 usefulness jackscrews are fixed on the center stand column 1, as shown in Figure 2: two gripper shoes 6 of adjacent two broadstep 2 other ends are by vertical slot 7 and laterally slot 8 usefulness securing members 9 are fixing, on gripper shoe 6, use bolt railing 10, the least significant end of railing 10 supports on the ground, top is used bolt with terraced apical ring 11 respectively successively, one end and the center stand column 1 of ladder apical ring 11 are used bolt, and the other end and last root railing 10 are fixing.

Its advantage is: simple in structure, easy to use, detachable, can install at Different field, and the height of adjacent stair tread and width are all adjustable, have saved installing space.
