Abstract
The utility model discloses an assembled swivel ladder which comprises a central post, swivel ladder steps, an annular base, telescopic supporting legs and telescopic universal rollers, wherein a tubular column is formed at one end of each swivel ladder step, and the corner of the tubular column is positioned through a positioning concave opening and a positioning convex opening arranged on the tubular column. The assembled swivel ladder is convenient to disassemble and can move freely, and is particularly suitable for places where stairs are required to be temporarily built.
Description
Technical field
The utility model relates to a kind of saw, specifically, is a kind of saw that assembles.
Background technology
The direct-discharging stair that saw is traditional relatively, have take up space little, advantage such as both artistic and practical.The present saw that uses, the fixed structure that employing can't be dismantled be installed on two-layer between, take fixed space, be unfavorable for maintenance and make, be not suitable for the occasion that some temporary needs is used stair.
The utility model content
The purpose of this utility model is to provide a kind of saw convenient and that can move flexibly of installing and removing, and is particularly suitable for the occasion that some need build stair temporarily.
For solving above technical problem, a kind of assembling saw that the utility model provides, comprise central post (1), saw step (2), annular base (3), telescopic support legs (4) and flexible universal rolling wheel (5), key is: described saw step (2) one ends have the tubulose post, the upper end circumference of described tubulose post is provided with location tang (2a), its lower end circumference is provided with positioning recess (2b), and described positioning recess (2b) relative positioning tang (2a) rotates an angle on circumference; Described central post (1) lower end is plugged in the centre bore of described annular base (3), the described saw step (2) is parallel to each other from down to up and be sleeved on evenly and at intervals on the described central post (1), described telescopic support legs (4) and flexible universal rolling wheel (5) are contained in the lower end of annular base (3) and respectively have circle distribution of one's own, and described telescopic support legs (4), flexible universal rolling wheel (5) are threaded with described annular base (3).
Further, the end of described saw step (2) away from the tubulose post is equipped with guardrail (6), and railing (7) is equipped with in the top of (6) of described guardrail, and described railing (7) twist.
Location tang and the positioning recess of the utility model by saw step has a certain degree and realizes that a plurality of saws steps rise along the central post spirality, and its beneficial effect is:
1) compact conformation, the modes of grafting or suit that adopt are dismantled, assembled more, and are convenient and swift;
2) move to the different location by flexible universal rolling wheel and use,, have flexibility and steadiness concurrently again by the telescopic support legs fixed support;
3) guardrail of She Zhiing and railing make integral body more elegant in appearance and safe and reliable.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the assembling schematic diagram of annular base and telescopic support legs.
Fig. 3 is the saw stereogram in step.
Fig. 4 is an inversion state schematic diagram of the present utility model.
Fig. 5 is the scheme of installation of the utility model and double-decker.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 1, a kind of assembling saw shown in Figure 4, form by central post 1, saw step 2, annular base 3, telescopic support legs 4, flexible universal rolling wheel 5, guardrail 6 and railing 7.Central post 1 is a cylinder, and saw step 2 is parallel to each other from down to up and be sleeved on evenly and at intervals on the central post 1.Central post 1 lower end is the ladder cylinder, has the ladder cylindrical hole at the center of annular base 3 accordingly, and central post 1 lower end is plugged in the centre bore of annular base 3.Telescopic support legs 4 and flexible universal rolling wheel 5 are contained in the lower end of annular base 3, and telescopic support legs 4, flexible universal rolling wheel 5 are threaded with annular base 3, stretch by precession or back-out screw thread.One end in saw step 2 is contained on the central post 1 by the tubulose column sleeve, away from the other end of tubulose post guardrail 6 is housed; The lower end of guardrail 6 linked to each other with the saw step 2, and railing 7 is equipped with in the upper end of guardrail 6, and railing 7 rises along guardrail 6 spirals, and guardrail 6 twist.
As shown in Figure 2, telescopic support legs 4 is contained in the lower end of base 3 and becomes circle distribution.In conjunction with Fig. 1 as can be known, flexible 5 one-tenth circle distribution of universal rolling wheel, telescopic support legs 4 is positioned on the circumference in flexible universal rolling wheel 5 outsides.
As shown in Figure 3,2 one-tenth of saw steps are fan-shaped, and saw goes on foot 2 one ends and has the tubulose post, and the tubulose post links to each other with fan-shaped small end, and its axis normal is in fan-shaped plan.The upper end circumference of tubulose post is provided with location tang 2a, and its lower end circumference is provided with positioning recess 2b, and positioning recess 2b relative positioning tang 2a rotates a certain angle on circumference.Location tang 2a is that the circumferential section extension of tubulose post upper end forms, and positioning recess 2b is the breach of being opened on the circumference of tubulose post lower end.Location tang 2a and positioning recess 2b respectively are two, and be uniform on each comfortable upward circumference or the following circumference.Certainly; also positioning recess 2b can be arranged on the upper end circumference of tubulose post; tang 2a is arranged on the lower end circumference of tubulose post with the location; the quantity of location tang 2a and positioning recess 2b is not limited to two; the above; all belong to simple deformation of the present utility model, all drop within the protection domain of the present utility model.
As shown in Figure 4, during installation, earlier central post 1 is plugged on the annular base 3, central post 1 is kept flat, again the saw step 2 is sleeved on the central post 1 successively, and determine relative rotation by the location tang and the positioning recess in saw step 2, by bracing frame 8 auxiliary installations, bracing frame 8 is used to keep central post 1 level, prevent that central post 1 from tilting to damage the saw step 2, load onto telescopic support legs 4, flexible universal rolling wheel 5 and the flexible universal rolling wheel 5 of adjusting and exceed telescopic support legs 4, at last saw is erected.Utilize flexible universal rolling wheel 5 to move to the position that needs to use saw, regulate telescopic support legs 4, make saw perpendicular to the ground, regulate telescopic support legs 4 and will assemble the saw support on the ground, regulate flexible universal rolling wheel 5 built on stilts again, at last guardrail and railing are loaded onto.
Figure 5 shows that the scheme of installation of assembling saw and double-decker, double-decker has the upper strata envelope and has the back balcony, the assembling saw is installed in the envelope rear side, ground and back balcony are coupled together, it is little to take up room, elegant in appearance, just use saw when having determined to get on the bus, will accept after its dismounting more when not required.
