Locking device at bottom of container door panel

Abstract

The invention discloses a locking device at the bottom of a container door panel. The locking device comprises a plurality of U-shaped or H-shaped lock seats fixed on the lower portion of the door panel. Lock hooks corresponding to the lock seats and hooked onto the same are disposed on the front end face of a threshold. Pull rods are connected to the lock hooks. The locking device is characterized in that the pull rods are connected with swing arms mounted on the lower surface of a base plate by through holes in the threshold, the swing arms are fixed on a lock rod, the outer end of the lock rod is connected with a swing handle through a pin, the outer surface of a container lateral plate on the side with the swing handle is provided with a limit block, the limit block exactly clamps in front of the swing handle to prevent the swing handle from rotating so as to release locking when the lock hooks are hooked onto the lock seats and locked with the same, and an anti-disconnection device used when the swing handle is located at a locking position and a swing handle positioning device used when the lock hooks release locking are further disposed on the outer surface of the container lateral plate. The locking device is simple in structure, reliable in locking and convenient to use.

Description

technical field [0001] The invention relates to a container, in particular to a locking device for the bottom of a container door panel. Background technique [0002] Containers have become an international standard means of transport for multimodal transport. A common container includes: a bottom plate and side plates on both sides of the bottom plate, a top plate fixed to the two side plates opposite to the bottom plate, an end plate at one end of the bottom plate and fixed with the two side plates and the top plate, and on the other side of the bottom plate The corner posts at one end are respectively fixed with openable door panels. A locking device fixed to the base plate and the door plate is arranged on the door plate. However, when the ordinary locking device is full of goods in the container, under the strong impact force during transportation, the bottom of the door panel and the lower beam of the door frame are easily deformed and gaps appear, and the goods in t...

Problems solved by technology

However, when the ordinary locking device is full of goods in the container, under the strong impact force during transportation, the bottom of the door panel and the lower beam of the door frame are easily deformed and gaps appear, and the goods in the container are lost or leaked from the gaps. environmental pollution

Although there is a container in the patent 2009100917202, which can better solve the locking of the door panel and the bottom panel, it must bend the bottom panel upwards to form an accommodation space under the bottom panel for installing the locking device, which will cause poor versatility of the container , forming a hurdle at the door of the container, which brings difficulties to unloading

In addition, a driving device is still needed, and the driving device needs a pair of bevel gears, a cylinder or a driving cylinder of an oil cylinder, etc., the structure is very complicated, the manufacturing cost is high, the reliability is also poor, and the use is troublesome
