Variable caliber type object containing bucket

Abstract

The invention discloses a variable caliber type object containing bucket. The object containing bucket is characterized in that edge deformation on the upper part of a bucket body is restrained by the lifting operation of an inner lantern ring and an outer lantern ring so as to achieve the shrinkage and expansion of the mouth of the object containing bucket. The variable caliber type object containing bucket is mainly composed of a bucket body, a lantern ring body and a pair of shrinking handles, wherein the bucket body is formed by removing the shells of an upper section of prism, a lower section of prism and a middle section of pyramid; the junction of the pyramid and the lower section of prism is in fillet transition; the position from the bucket mouth to the upper part of the lower section of prism is divided into the edges with the same width along an arris edge; a widened arris seam is used for penetrating the connecting tendon of the lantern ring body; the outer side of the lower section of prism is provided with a bent groove along the bottom edge of the edges; the lower part of the lower section of prism is symmetrically provided with shrinking handle mounting holes; the lantern ring body can be formed spliced by adhering the inner lantern ring and the outer lantern ring which are of pyramid shapes; the outer side of the inner lantern ring is symmetrically provided with a plurality of connecting tendons along the edges; the connecting tendons divide an inner / outer lantern ring gap into a plurality of equal sections so as to be used for embedding the correspondingbucket body edge; and each shrinking handle is provided with a spring bolt, a handle and a tapped hole for locking the lantern body moving to the bottom and cooperating an expansion handle to upwardly move the lantern ring body.

Description

Technical field [0001] The invention relates to a barrel-shaped container, in particular to a variable-diameter storage barrel capable of changing the size of the mouth of the barrel. Background technique [0002] Traditional storage bins (such as trash cans, etc.) are difficult to match with storage bags (such as garbage bags, etc.) of different calibers due to their fixed caliber. A storage bag with too small a caliber is difficult to fold over the mouth of the storage bucket, which often leads to waste and waste; while a storage bag with an overly large caliber can be folded into the storage bucket, but it is easy to cause loosening and slipping, and wastes the original volume. [0003] The main principle of the domestic related patents (such as variable-caliber garbage cans) that have been disclosed is: the upper part of the inverted conical barrel body is divided into several open barrel flaps, and the outer barrel (or ring) that is threadedly connected with the lower p...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to make up for the shortage that the existing storage barrels are difficult to adapt to different caliber storage bags, the present invention provides a variable-diameter storage barrel, which can constrain the upper part of the barrel through the lifting operation of the inner and outer rings. The ribs are deformed to realize the shrinkage and expansion of the storage bucket mouth
