Structural design of ladder product

Abstract

The invention discloses a structural design of a ladder product, which comprises a ladder body consisting of two vertical bamboo tubes and a plurality of sections of transverse ladder rod pedal tubes, the bottom of the vertical bamboo tube of the ladder body is sleeved with an adjusting support seat, the adjusting support seat and the ladder body are fixed through a transverse pin, the adjusting supporting seat comprises an adjusting portion and a supporting portion, the supporting portion is provided with a supporting plane, the outer ring of the supporting plane extends to the outer ring of the supporting portion through a bevel edge, and supporting nails are evenly arranged on the bottom face of the supporting portion along the circumference. The ladder disclosed by the invention can be suitable for an uneven ground, particularly an uneven soft mud ground, and can be stably fixed, and the ladder cannot slip during climbing, so that the safety of a worker is ensured.

Description

Technical field [0001] The present invention belongs to the field of manufacture of tools, in particular to the structural design of a ladder product. Background [0002] In rural areas and traditional use of ascending tools are mostly bamboo ladders, consisting of two vertical bamboo tubes and several sections of transverse ladder pole pedals, the ladder of this technology has the advantages of light weight and low manufacturing cost. Because the bottom surface of the ladder should be supported by a flat and hard ground, but in the actual use process, especially in the field operation, some of the ground is uneven and relatively soft mud, after the ordinary ladder is put up, one foot of the ladder will sink into the soil, causing the whole set of ladders to tilt, there is a great danger, if you have to climb up, due to the upward movement of the center of gravity when climbing, it is easy to cause the ladder to slip and fall, posing a threat to the safety of the staff.

AI Technical Summary

Problems solved by technology

Since the bottom surface of the ladder must be supported by flat and hard ground, however, in actual use, especially when working in the field, some ground is uneven and soft muddy ground. After the ordinary ladder is put on, one foot of the ladder It will sink into the soil, causing the whole set of ladders to tilt, which is very dangerous. If you insist on climbing up, the ladder will easily slip due to the upward movement of the center of gravity when climbing, posing a threat to the safety of the staff.
