Description

Landing leg

Technical Field

The utility model relates to a supporting leg.

Background

The trailer is a vehicle which is towed by a car and has no power driving device, and is a combination of a car (truck, tractor or forklift) and one or more trailers, wherein the truck and the tractor are driving sections of a car train, called a main car, and driven sections towed by the main car are called trailers, so that the trailer becomes a main force army for highway transportation. The legs are supporting means of the trailer and serve to support the ground when the tractor is unhooked, bearing the front half load of the trailer. The landing leg mainly includes supporting seat, bracing piece, supporting sleeve and drive mechanism from the structure, and current supporting sleeve adopts integral type square tube structure more, and welded fastening has the flank on the lateral wall on square tube upper portion, processing fixed through-hole on the flank, and this fixed through-hole passes through the locating plate on bolt and the trailer to be connected fixedly, and the flank is main atress position when the landing leg is used, because the welding area between flank and the square tube is less, the whole bearing capacity of flank is limited.

Disclosure of Invention

In view of the above-mentioned shortcomings, the present utility model provides a leg.

In order to achieve the above purpose, the utility model provides a supporting leg, which comprises a supporting sleeve and a supporting rod which is slidably arranged in the supporting sleeve, wherein the lower part of the supporting rod extends out of the supporting sleeve and is hinged with a supporting base through a rotating shaft;

the support sleeve comprises a U-shaped plate which is vertically arranged, a side plate is arranged at the opening of the right side of the U-shaped plate, the U-shaped plate and the side plate enclose to form a square tube structure, the front side and the rear side of the side plate extend towards the width direction to form fixed flanks, and fixed through holes are symmetrically machined on the fixed flanks.

As a further improvement of the utility model, the U-shaped plate and the side plate are fixed by welding.

As a further improvement of the utility model, the fixing through holes are uniformly distributed along the height direction of the fixing flanks.

As a further improvement of the utility model, the U-shaped plate is formed by bending a metal plate.

As a further improvement of the utility model, the width of the lower part of the side plate is gradually reduced, and the minimum width of the side plate is matched with the width of the opening of the U-shaped plate.

The beneficial effects of the utility model are as follows:

in the support leg structure, the support sleeve adopts a U-shaped plate and a side plate to form an integrated square pipe structure after being welded, the welding area between the U-shaped plate and the side plate is large, the whole structure is stable, the two sides of the side plate extend to form fixed flanks and process fixed through holes, and the support bearing capacity is larger; the U-shaped plate is formed by bending metal plates, the processing technology is simple, the area of the plate integrally used by the supporting sleeve is reduced, and the production cost of the product is reduced.
