Description

A kind of adjustable cat ladder

Technical field

A kind of cat ladder is the utility model is related to, particularly a kind of adjustable cat ladder.

Background technology

Cat ladder is a kind of family expenses and the conventional apparatus of open air, also especially suitable in engineering, but on-site, typically adopt Cat ladder is directly built with steel pipe, steel pipe is generally cylindric, as supporting structure, steps on and easily slips, considerably increase and apply The danger of work, while in work progress, climbing cat ladder can also often carry out some material transportations, or step down on cat ladder and applied Work operates, and the existing cat ladder set up using steel pipe or batten is difficult to the safety for ensureing job site.

Utility model content

Goal of the invention of the present utility model is to overcome the cat ladder set up using steel pipe or batten, climbing inconvenience, easily slided , the above-mentioned deficiency such as safely is influenceed, there is provided a kind of adjustable cat ladder, it is simple in construction, reasonable in design, be advantageous to prevent that fastener is loose It is dynamic, further strengthen steadiness.

To achieve these goals, the technical solution adopted in the utility model is：

A kind of adjustable cat ladder, the pedal comprising four straight-bars He several rectangles, all pedal parallel intervals Between four straight-bars, the opposite sides of the pedal is respectively connected with two straight-bars, and the pedal is respectively with four The individual straight-bar is connected by axis of rotation, and it is arranged in parallel to connect all rotating shafts of the pedal and straight-bar, the pedal The limiting component of the restricted pedal rotation is connected between straight-bar.

Using a kind of adjustable cat ladder of the present utility model, the pedal comprising four straight-bars He several rectangles, Suo Yousuo Being located between four straight-bars for pedal parallel interval is stated, the opposite sides of the pedal is respectively connected with two straight-bars, The pedal is connected with four straight-bars by axis of rotation respectively, and all rotating shafts for connecting the pedal and straight-bar are mutually flat Row is set, and the limiting component of the restricted pedal rotation is connected between the pedal and straight-bar, and trample part uses several The pedal of rectangle, compared in general pipe, square tube, it is bigger to trample area, safer in climbing, especially climbs bearing a heavy burden When, it is not easy to slip, the pedal formed compared to folding and expanding is more smooth using the pedal trample part of monoblock rectangle, The safety of climbing is advantageously ensured that, while can avoid damaging caused by frequently folding, the straight-bar there are four, is easy to climbing When be used as handrail, when in use, the straight-bar of the pedal side adjusts placed angle, the institute of opposite side according to field condition Straight-bar expansion is stated, the pedal rotates around the axis, then fixed by the limiting component, and the pedal can be protected in use Water holding is put down, and is easy to climb, and safety coefficient is higher, because all straight-bars land, support it is more stable, stress evenly, energy Enough avoid backward toppling in climbing, need not reversely turn the pedal around the shaft in use, unclamp the limiting component Move to gathering, then fixed by the limiting component, it is convenient to carry and stack, the peace of climbing is advantageously ensured that using the present apparatus Entirely, it is not easy to slip, safety coefficient is higher, and support is more stable, and stress evenly, can avoid backward toppling in climbing, convenient Carry and stack, simple in construction, easily manufactured, cost is cheap.

Preferably, all shaft parallels of the pedal and straight-bar are connected in longer one side of the pedal.

Using above-mentioned set-up mode, i.e., when the cat ladder deploys, one side longer along the pedal is climbed, and is more convenient.

It is further preferred that between the two neighboring pedal be smaller than or the width equal to the pedal.

Using above-mentioned set-up mode, i.e., when the cat ladder collapses, being projected as between the pedal is continuous, Neng Gouzhi The place for placing it in the needs such as ground is connect, builds provisional passageway.

Preferably, the limiting component is located on two pedals at the straight-bar both ends, connects on each pedal It is connected to four limiting components.

Two pedals i.e. positioned at top and bottom are provided with the limiting section with each straight-bar junction Part, it is more stable when fixing.

Preferably, the limiting component includes the groove one on the pedal, the groove two on the straight-bar With the latch for connecting the groove one and groove two.

After the angle adjustment of expansion is good, the latch is inserted between the groove one and groove two and is fixed.

Preferably, the end of all straight-bars is provided with extensible member.

When ground slightly not usually, the length of the single straight-bar can be entered by the extensible member of the straight-bar end Row regulation, it is easy to place stable, increase safety coefficient.

Preferably, the size shape all same of all straight-bars and it is parallel to each other.

Preferably, four straight-bars are connected to an angle of the pedal.

Preferably, it is raised to be provided with several for the pedal.

Be advantageous to provided with several projections anti-skidding.

Preferably, all straight-bars and pedal are Al-alloy products.

In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：

1st, using a kind of adjustable cat ladder of the present utility model, the safety of climbing is advantageously ensured that, is not easy to slip, safety system Number is higher, and support is more stable, and stress evenly, can avoid backward toppling in climbing, convenient to carry and stack, structure letter Single, easily manufactured, cost is cheap.

2nd, using a kind of adjustable cat ladder of the present utility model, climb, be more convenient along the long side of the pedal.

3rd, using a kind of adjustable cat ladder of the present utility model, being projected as between the pedal is continuous, can be direct The place of the needs such as ground is placed it in, builds provisional passageway.

4th, using a kind of adjustable cat ladder of the present utility model, by the extensible member of the straight-bar end to single described The length of straight-bar is adjusted, and is easy to place stable, increase safety coefficient.

5th, using a kind of adjustable cat ladder of the present utility model, the pedal is provided with several projections, is advantageous to anti-skidding.
