Description

Multifunctional ladder stand

Technical Field

The utility model relates to an affiliated facilities field, in particular to multi-functional cat ladder.

Background

With the rapid development of economy and urban infrastructure in China, the demand for various new building materials is increasingly strengthened. As an accessory for building construction, the form and function of ladders has not improved much for a long time. The cat ladder is an indispensable instrument in the building work process, and is difficult for depositing at the scene because the characteristics of traditional cat ladder self at the job site, and the cat ladder of the interim equipment of on-the-spot workman adoption in many times.

The utility model provides a multifunctional crawling ladder has solved among the prior art great, the difficult scheduling problem of depositing, function singleness of crawling ladder weight, the utility model has the advantages of reasonable design, convenient operation has improved the working property of crawling ladder greatly, has improved job stabilization nature.

SUMMERY OF THE UTILITY MODEL

In order to overcome the single not enough that does not deposit well at the job site of traditional cat ladder usage, the utility model provides a multi-functional cat ladder, this cat ladder can not only have multiple service function, can reduce the transport condition at scene moreover.

The utility model adopts the following technical proposal:

the utility model provides a multifunctional ladder stand, includes handrail frame, fixed footboard, movable footboard, fixed footboard and movable footboard are connected to the bearing, and the back of movable footboard has fixed hoop, has the iron sheet that can promote in the fixed hoop, when needs use the ladder stand as scaffold frame or bridge plate, pave movable footboard, with fixed footboard a horizontal plane, insert the corresponding hole that handrail frame left with this fixed movable footboard with the iron sheet in the fixed hoop at the back of the movable footboard again, the back welding of movable footboard has the iron plate.

Preferably, one end of the iron sheet is bent outwards to be fixed in the fixed iron ring.

Preferably, the distance between the iron block and the proximal end of the movable pedal is equal to the length of the iron sheet.

Preferably, the one fixed pedal (2) and the two movable pedals (3) may be respectively connected by two bearings (4).

Preferably, the fixed pedals can be respectively perpendicular to the movable pedals at two sides, and the iron sheets at the back of the movable pedals are inserted into the corresponding holes reserved on the handrail frame.

Preferably, the handrail frame corresponds to a hole when the movable pedal and the fixed pedal are on a horizontal plane and vertical to each other, and the length of the hole is equal to the width of the iron sheet.

The utility model has the advantages that: (1) each ladder plate of the multifunctional ladder stand is only provided with three pedals, so that the material is saved, and the budget is reduced. (2) The movable pedal can be connected with the fixed pedal through a bearing, so that the movable pedal and the fixed pedal can rotate to a plane, and the movable pedal can be used as a scaffold or a bridge plate, and the function of climbing stairs is increased.

Detailed Description

The utility model is described in detail with the following figures:

the utility model provides a multifunctional ladder stand, includes handrail frame 1, fixed footboard 2, movable footboard 3, bearing 4, fixed hoop 5, iron sheet 6, iron plate 7, fixed footboard 2 and movable footboard 3 are connected to bearing 4, and movable footboard 3's back has fixed hoop 5, has iron sheet 6 that can promote in the fixed hoop 5, and handrail frame 1's inboard leaves the hole that iron sheet 6 can insert, fixes movable footboard 3, and movable footboard 3's back welding has iron plate 7. One end of the iron sheet 6 is bent outwards and fixed in the fixed iron ring 5. The distance between the iron block 7 and the near end of the movable pedal 3 is equal to the length of the iron sheet 6. The one fixed pedal 2 and the two movable pedals 3 may be respectively connected by two bearings 4. The fixed pedal 2 can be respectively vertical to the movable pedals 3 at two sides, and the iron sheets 6 at the back of the movable pedals 3 are inserted into the corresponding gaps left on the handrail frame 1. The handrail frame 1 is respectively corresponding to a hole when the movable pedal 3 and the fixed pedal 2 are on a horizontal plane and vertical, and the length of the hole is equal to the width of the iron sheet 6.

In the using process, when the ladder stand is used as a scaffold or a bridge plate, the movable pedal 3 is paved to be on the same horizontal plane with the fixed pedal 2, and then the iron sheet 6 in the fixed iron ring 5 on the back of the movable pedal 3 is inserted into the corresponding hole reserved in the handrail frame 1 so as to fix the movable pedal 3. When the ladder is used as a ladder stand, the fixed pedal 2 is respectively vertical to the movable pedals 3 at two sides, and the iron sheets 6 at the back of the movable pedals 3 are inserted into corresponding holes reserved on the handrail frame 1.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
