Description

Portable limiting device for preventing inner leg from falling down automatically

Technical Field

The utility model relates to the technical field of vehicles, in particular to a portable limiting device for preventing inner legs from falling down automatically.

Background

With the rapid development of the logistics industry in recent years, the development trend of the semitrailer industry is better and better, and the trailer supporting device is used as an important accessory of the trailer and has a great effect in the use of the semitrailer.

The utility model relates to an improvement on the technical scheme of a supporting device for preventing an inner leg from falling down automatically, which is characterized in that a limiting chain is adopted to limit a crank shaft connector, the other end of a mounting lug is mounted on a fixed threaded column of an extension shaft at the side surface of the top end of a supporting device body, and the mounting and the dismounting of the limiting chain are troublesome due to the structure through a nut, a spanner or a sleeve is needed to be used for taking down the nut, and the rapid switching between the front state and the rear state of the supporting operation cannot be realized rapidly.

Disclosure of Invention

The utility model aims to provide a portable limiting device for preventing inner legs from falling down automatically, so as to solve the problems in the background technology.

In order to solve the technical problems, the utility model provides the following technical scheme: the utility model provides a prevent that inner leg falls certainly and uses portable stop device, includes couple, installs the chain on the couple and fixed the setting at the installation ear of chain one end, install the closure pole through the round pin axle rotation on the couple, be equipped with the screw thread on the closure pole, and it is gone up to twist and be equipped with the nut cover, the closure pole passes through the nut cover switching couple.

A rubber pad is stuck on the inner side wall of the upper end of the hook.

The surfaces of the hooks, the chains and the mounting lugs are coated with an anti-corrosion layer.

The tail end of the closing rod is arranged in a manner of being matched with the end part of the hook.

Compared with the prior art, the utility model has the following beneficial effects: the utility model is an improvement made on the technical scheme of the supporting device for preventing the inner leg from falling down by self in the patent name of the prior application, and the supporting device is arranged on the supporting device body in a hook way, so that the rapid switching between the front state and the rear state of the supporting operation can be realized rapidly, and the operation is convenient and rapid.
