Description

Folding type supporting leg device

Technical Field

The utility model relates to a landing leg device specifically is a support and fixed foldable landing leg device for AGV dolly.

Background

The supporting legs of the AGV are auxiliary devices commonly used in work, the AGV is used for fixing and supporting the AGV carrying objects, and the common supporting legs are mainly fixed and adjustable. The existing support leg needs to realize two states of folding and supporting frequently in some cases, and the structural form of the existing support leg has two general forms during folding and supporting:

1. the two states of folding and supporting are completed by frequently mounting and dismounting parts by using tools, and the form invisibly increases the labor intensity;

2. many of the prior supporting legs are only in the form of directly mounting a supporting member at the bottom of a fixing seat, when the supporting and retracting are needed, the integral action of the fixing seat and the supporting member is needed so as to retract and support, that is, the retracting and the supporting are all integrally carried out, and the defects are that:

2.1, the operation is relatively laborious due to the integral retraction and support;

2.2, because the whole body needs to be folded and supported, the operation radius is larger and a larger operation space is needed during operation;

2.3, because of the need for integral stowing and support, even in the stowed state, the space it occupies is even greater.

In addition, when the supporting legs are folded, the existing supporting legs are difficult to obtain a large ground clearance, so that the situation that the ground is accidentally bumped or rubbed even if the supporting legs are folded is easily caused;

in conclusion, the existing AGV trolley supporting leg form wastes time and labor in the process of folding or supporting, and the labor intensity is high. And the prior support leg has certain limitation in application.
