Description
Technical Field
[0001] The utility model relates to the field of corrugated cartons, in particular to a corrugated carton with a novel connection structure. Background Art
[0002] The corrugated carton is an ideal packaging container. It has the characteristics of being light, firm, shock-absorbing and suitable for mechanized production. It has been used in transportation packaging and sales packaging for many years. In addition to protecting goods, facilitating storage and transportation, it also plays a role in beautifying and promoting goods.
[0003] However, in the prior art, there are the following defects:
[0004] The existing corrugated cartons are either folded from a whole piece of corrugated paper or nailed with glue or sealing nails. The connection structure is simple and not very firm and stable. When heavier items are loaded in the corrugated carton, it is easy to cause the connection structure of the carton to come apart and be damaged, affecting the use. Content of the Utility Model
[0005] The purpose of the utility model is to provide a corrugated carton with a novel connection structure to solve the problems put forward in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A corrugated carton with a novel connection structure, including a carton body and a box cover. The carton body includes two first side plates, two second side plates and a bottom plate. The first side plate includes a first mounting cardboard, a corrugated cardboard and a cover. A U-shaped frame is fixedly installed on one side of the first mounting cardboard. Third card slots are opened on both sides of the U-shaped frame, and a fourth card slot is opened at the bottom of the U-shaped frame. At both ends of one side of the second side plate, first card strips are fixedly installed, and the two first card strips are respectively snap-fitted into the third card slots on one side of the two U-shaped frames.
[0007] Adopting the above technical solution, in this solution, the first card strip is snap-fitted into the third card slot on the side of the U-shaped frame, and is connected by a mortise and tenon structure. The connection is tight and not easy to fall off, and there is no need for glue, sealing nails, etc., which will not pose a safety hazard to users.
[0008] The bottom of the U-shaped frame intersects with the bottom of the first mounting cardboard. A plurality of first card slots are opened on both sides of the end of the U-shaped frame far from the first mounting cardboard, and a plurality of second card slots are opened at the bottom of the end of the U-shaped frame far from the first mounting cardboard. A groove is formed between the U-shaped frame and the first mounting cardboard.
[0009] Adopting the above technical solution, in this solution, the U-shaped frame facilitates the connection between the first side plate, the second side plate and the bottom plate.
[0010] A plurality of through grooves are formed on the side surface of the first card strip. After the first card strip is snap-fitted into the third card slot, the through grooves communicate with the first card slot.
[0011] With the above technical solution, the through grooves on the first card strip communicate with the first card slot, combining to form a card slot.
[0012] A corrugated cardboard is fixedly installed inside the groove. A plurality of first clamping blocks are fixedly installed at both ends on one side of the cover. A plurality of second clamping blocks are fixedly installed at the bottom on one side of the cover. The first clamping blocks are arranged corresponding to the first card slots, and the first clamping blocks are snap-fitted inside the first card slots.
[0013] With the above technical solution, the corrugated cardboard is filled in the groove to prevent the inside of the first side plate from being hollow, strengthening the hardness of the first side plate. The first clamping blocks on both sides of the cover are snap-fitted inside the first card slot and the through groove, further ensuring a tight connection between the first side plate and the second side plate.
[0014] A fifth card slot is formed at the bottom of the second side plate. Second card strips are fixedly installed on both sides at the top of the bottom plate. Third card strips are fixedly installed on the other two sides at the top of the bottom plate. The second card strips are snap-fitted inside the fourth card slots, and the third card strips are snap-fitted inside the fifth card slots.
[0015] With the above technical solution, the bottom plate is snap-fitted and connected to the bottom of the first side plate and the bottom of the second side plate through the second card strips and the third card strips respectively.
[0016] A plurality of sixth card slots are formed on the side of the second card strip. After the second card strip is snap-fitted into the fourth card slot, the sixth card slots communicate with the second card slot. The second clamping blocks are arranged corresponding to the second card slots, and the second clamping blocks are snap-fitted inside the second card slots.
[0017] With the above technical solution, the second clamping blocks are snap-fitted inside the sixth card slots and the second card slots, further strengthening the firmness of the connection between the bottom plate and the first side plate.
[0018] A handle is formed at the middle position between the two second side plates. A protective buckle is arranged inside the handle. A box cover is sleeved on the top of the carton body.
[0019] With the above technical solution, the handle facilitates the handling of the corrugated carton, and the protective buckle can prevent people's palms from being bruised.
[0020] Compared with the prior art, the beneficial effects of the present utility model are:
[0021] Between the first side plate and the second side plate of the utility model, they are clamped and connected through a U-shaped frame and a first clamping strip, and then the first clamping block and the second clamping block of the cover are used for further reinforcement. Similarly, for the bottom plate, the first side plate and the second side plate, after being connected by a mortise and tenon structure, they are further reinforced through a card slot and a buckle, making the corrugated cardboard box tightly and firmly connected, and extending the service life of the corrugated cardboard box.
