Technical Field

[0001] The utility model relates to the technical field of cartons, in particular to a carton with a pull-type folding structure. Background Technique

[0002] As a kind of lightweight, economical and easy-to-process packaging material, cartons are widely used in aspects such as commodity packaging, transportation and temporary storage. Common storage cartons are usually made of corrugated cardboard, including a box body and a box cover, and rely on the folding and plugging of corrugated cardboard to achieve a fixed shape.

[0003] With the modern people's emphasis on the pursuit of space utilization efficiency, traditional cartons gradually show limitations in actual use. For example, the fixed volume of the carton cannot be adjusted according to actual needs, the storage space is limited, and once the stored items exceed the volume of the box body, the box cover cannot be normally closed, resulting in inconvenient use.

[0004] Therefore, there is an urgent need for a carton with a pull-type folding structure to solve the technical defects mentioned in the above technology. Content of the Utility Model

[0005] The purpose of the utility model is to provide a carton with a pull-type folding structure to solve the problems that the fixed volume of the carton cannot be adjusted according to actual needs, the storage space is limited, and once the stored items exceed the volume of the box body, the box cover cannot be normally closed mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A carton with a pull-type folding structure, including a box body and a box cover. A tarpaulin bag is assembled on the inner wall of the box body. The top of the tarpaulin bag is bonded with the box cover. A set of rod sleeves are respectively fixed on both sides of the box cover. Hook rods are sleeved inside the rod sleeves. A set of knobs are installed on both sides of the outer wall of the box body. Rotating blocks are hinged at the knobs. Limit blocks are arranged above the rotating blocks and are fixed to the outer wall of the box body. Lock holes are opened in the rotating blocks. The bottom ends of the hook rods are embedded and fixed in the lock holes. A set of spring grooves are arranged on both sides of the outer wall of the box body. Spring lock blocks are inserted into the spring grooves. Inner grooves are opened on the side walls of the rod sleeves and the hook rods. Multiple groups of the inner grooves are equidistantly distributed on the side wall of the hook rod. The spring lock blocks penetrate into the inner grooves. Flappers are welded to the bottom ends of the spring lock blocks.

[0007] Preferably, when the rotating block is in a horizontal flipping state, its top abuts against the bottom end of the limit block, and the maximum rotation angle of the rotating block is 0-270°.

[0008] Preferably, the bottom end of the tarpaulin bag is fixed to the inner wall of the box body through a hook. The length and width of the tarpaulin bag are both smaller than the box cover. When the box cover is pressed on the top of the box body, the tarpaulin bag can be stored in the box body and the box cover.

[0009] Preferably, four sets of fixing plates are welded on both sides of the inner wall of the tarpaulin bag, and a scissor frame formed by hinged connection of multiple sets of plastic rods is installed on the fixing plates.

[0010] Preferably, a group of side grooves are respectively opened on both sides of the top of the box cover, and two groups of slides are respectively opened in the side grooves. A group of spring rods are fixed in each of the slides, and the ends of the spring rods are fixedly connected with sliders. There are four groups of sliders in total and they slide in the slides.

[0011] Preferably, an elastic strip is welded on one side of the slider, and the elastic strips extend upward together and are fixed to the handle.

[0012] Preferably, the outside of the handle is covered with ventilation holes, the handle and the elastic strip together form an "X"-shaped structure, and a handle groove is provided in the middle of the top of the box cover, and the handle groove is located below the handle.

[0013] Preferably, the elastic strip and the handle are both made of nylon material.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the carton with a lifting and folding structure can not only realize the widening of the storage space by lifting, and realize a more stable folding and unfolding effect, but also realizes the handle structure to reduce the occupied space, so that it is convenient to take and use at any time;

[0015] (1) By providing a hook rod, a rotating block, a locking hole, a paddle, a spring locking block, a rod sleeve, and an inner groove, the carton can be pulled upward to expand the storage space. The hook rod is slightly bent outward so that its bottom end is disengaged from the locking hole of the rotating block, and the rotating block automatically rotates back to a vertical state. After the bottom is released, the paddle is pushed. Under the elastic force of the spring locking block, the spring locking block penetrates into the rod sleeve and the inner groove of the hook rod to lock the length, thereby fixing the length of the hook rod and the rod sleeve. The tarpaulin bag can be unfolded to a desired position as needed, thereby greatly widening the storage space, especially providing more flexibility when placing items;

[0016] (2) A tarpaulin bag, a scissor frame, a box cover, and a box body are provided. A scissor frame formed by hingedly connecting multiple sets of hinged rods is used as a side support on the inner wall of the tarpaulin bag. When the box cover is pressed and fixed on the box body, the tarpaulin bag is stored in the carton. At this time, the scissor frame is hinged to a nearly horizontal state. When the tarpaulin bag is unfolded, the scissor frame is also unfolded, providing expansion support for the tarpaulin bag, and having a more stable folding and unfolding effect;

[0017] (3) By providing a carrying handle, a slideway, a slider, an elastic strip, and a spring rod, on the top end of the lid, the carrying handle is fixed by four groups of elastic strips. When lifting the carrying handle, it drives the elastic strips to move upward. At this time, the slider slides within the slideway. When putting down the carrying handle, under the resilience of the spring rod, the elastic strips drive the slider to move back and reset within the slideway, and the carrying handle can be pressed into the carrying handle groove, reducing the occupied space and facilitating use at any time.
