High-strength telescopic carton

Abstract

The invention provides a high-strength telescopic carton. The high-strength telescopic carton comprises a telescopic mechanism, the telescopic mechanism comprises an outer box, an inner box is slidably connected to the interior of the outer box, a reinforcing plate is fixedly connected to the bottom of the inner box, a cover plate is fixedly connected to the top of the inner box, a storage groove is formed in the top of the cover plate, and the outer side of the inner box is fixedly connected with a supporting plate. According to the high-strength telescopic carton, the inner box is pulled to slide towards the outer side of the outer box, the inner box enables the overall volume of the carton to be increased, meanwhile, the inner box drives the reinforcing plates to swing, the reinforcing plates swing to be unfolded, the reinforcing plates enable the inner box to be stably expanded without dislocation, when the reinforcing plates are completely unfolded, the clamping blocks are clamped in the clamping grooves, at the moment, the upper connecting plates and the lower connecting plates are fixed through the clamping blocks, the reinforcing plate can play a supporting role through the upper connecting plate and the lower connecting plate, it is guaranteed that the inner box stretches out stably and does not fall off, and therefore the effects that the volume of the carton can be expanded, and use is convenient are achieved.

Description

technical field [0001] The invention relates to the technical field of cartons, in particular to a high-strength stretchable carton. Background technique [0002] Carton is the most widely used packaging product. There are various specifications and models of cartons. Commonly used are three-layer, five-layer, and seven-layer is rarely used. [0003] The size of the existing cartons is fixed, and the use space cannot be expanded. When the loaded items exceed the volume, it is necessary to replace the large-sized box, which is inconvenient to use. At the same time, some cartons can be expanded. After the volume is expanded, the overall strength of the carton will decrease. It will become smaller, easily cracked and dented during use, and cannot effectively protect the items inside. Contents of the invention [0004] In order to achieve the above purpose of expanding the volume of the carton, being easy to use, strengthening the strength of the carton, stabilizing the expan...
