[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons have three layers or five layers, and seven layers are less used. Each layer is divided into inner paper, corrugated paper, core paper, and face paper. The inner and face papers can be tea board paper or kraft paper, and the core paper is corrugated paper. The colors and feels of various papers are different, and the papers produced by different manufacturers (colors and feels) are also different.
[0003] Problems existing in the prior art:
[0004] The bottom surface of the existing carton is mostly supported by cardboard that is folded in a staggered manner. For the supporting surface formed by this bottom surface in a staggered manner, its weighing effect is such that for some heavier items, it is easily pressed down during handling, causing the items to fall, thereby reducing its weighing effect. Secondly, for the frame shape formed by the carton, it is easily deformed by external forces during handling and moving, thereby reducing its service life. Content of the Utility Model
[0005] The purpose of the utility model is to provide an environment-friendly reinforced carton, which can solve the problems that the bottom surface of the existing carton is mostly supported by cardboard that is folded in a staggered manner. For the supporting surface formed by this bottom surface in a staggered manner, its weighing effect is such that for some heavier items, it is easily pressed down during handling, causing the items to fall, thereby reducing its weighing effect. Secondly, for the frame shape formed by the carton, it is easily deformed by external forces during handling and moving, thereby reducing its service life.
[0006] The technical solution adopted by the utility model is specifically as follows:
[0007] An environment-friendly reinforced carton includes an outer retaining frame. The outer retaining frame is formed into a frame shape by gluing. Two stacked bottom plates are fixedly provided on the left and right sides of the bottom surface of the outer retaining frame, and double-sided tape is provided between the two bottom plates;
[0008] The front and rear ends of the bottom surface of the outer retaining frame are respectively connected to a folding member and a bottom support member;
[0009] An inner support frame is sleeved inside the outer retaining frame. The four corners of the inner support frame are respectively connected to four clamping members, and the four clamping members are respectively connected to the four corners of the outer retaining frame. Card slots are opened on both side plates at the upper ends of the edges of the outer retaining frame.
[0010] The folding member includes a first folding plate. The first folding plate is integrally and fixedly connected to the rear end of the bottom surface of the outer retaining frame, and a first crease is provided at the connection. Two first baffle plates are glued on the first folding plate.
[0011] Both ends of the front side of the first folding plate are integrally and fixedly connected to two inner folding plates respectively. The front side of the first folding plate is integrally and fixedly connected to the clamping plate, and the front side of the clamping plate is integrally and fixedly connected to the stirring support plate.
[0012] The bottom support member includes a second folding plate, on which two second baffle plates are glued. The rear side of the second folding plate is fixedly connected to two turning and stirring plates, and the two turning and stirring plates are symmetrically L-shaped.
[0013] The second folding plate is integrally and fixedly connected to the front end of the bottom surface of the outer retaining frame, and a second crease is provided at the connection. The second folding plate is adapted to the clamping plate through the concave holes opened.
[0014] Both of the two second baffle plates are adapted to the stirring support plate, and the two turning and stirring plates are respectively adapted to the two first baffle plates.
[0015] The inner support frame includes two mutually perpendicular and clamped plates, and a third crease is provided between the two plates.
[0016] All four of the buckle clip members include a corner clamping plate, and the upper vertical sides of the corner clamping plate are respectively fixedly connected to two outer clamping plates, and the two outer clamping plates are both L-shaped.
[0017] Each of the corner clamping plates is adapted to the inner angle of the inner support frame.
[0018] On each of the buckle clip members, the two outer clamping plates are respectively sleeved in two card slots at the upper edges of the outer retaining frame, and the two outer clamping plates are attached to the outer sides of the two side plates at the upper edges of the outer retaining frame.
[0019] The technical effects achieved by the present utility model are as follows:
[0020] In the present utility model, through the arranged folding member, bottom support member and bottom plate, the folding member and the bottom support member can form a state of staggered connection and clamping, so that the bottom plate can be supported. Thus, when the bottom plate is pressed down, when the folding member and the bottom support member are pressed down, their staggered clamping connection can improve the clamping effect of the downward pressure and also improve the support effect on the bottom plate. Therefore, when the carton is used to carry some heavy items, its supporting effect can be improved and it can be prevented from falling.
[0021] In the present utility model, through the arranged outer retaining frame, inner support frame and buckle clip members, the inner support frame can form a corner clamping connection to the four corners of the outer retaining frame by relying on the buckle clip members, so as to improve the overall strength of the carton. Thus, some offset effects can be generated on the external force collision during the handling process, so as to avoid the deformation of the carton's outer shape and extend its service life.

[0035] According to the above structure, the clamping plate 24 can be correspondingly sleeved and turned up with the concave holes on the second folding plate 31, so as to facilitate the staggered folding production of cartons.
[0036] Refer to the appendix Figure 4 , the bottom support member 3 includes a second folding plate 31, two second baffle plates 32 are glued to the second folding plate 31, the rear side of the second folding plate 31 is fixedly connected to two turning plates 33, and the two turning plates 33 are arranged in a symmetric L shape.
[0037] Furthermore, the second folding plate 31 is integrally and fixedly connected to the front end of the bottom surface of the outer retaining frame 1, and a second crease is provided at the connection, and the second folding plate 31 is adapted to the clamping plate 24 through the opened concave holes, so that the second crease can drive the bottom support member 3 and the folding member 2 to perform staggered folding, thereby facilitating the folding to form a carton during application.
[0038] Even further, both of the two second baffle plates 32 are adapted to the bracing plate 25, and the two turning plates 33 are respectively adapted to the two first baffle plates 23.
[0039] According to the above structure, the bracing plate 25 and the clamping plate 24 on the folding member 2 are passed through the concave holes on the second folding plate 31 of the bottom support member 3.

[0045] The working principle of the present utility model is as follows: The stirring support plate 25 and the embedding clamping plate 24 on the folding member 2 pass through the concave holes on the second folding plate 31 on the bottom support member 3. At the same time, the two turning and stirring plates 33 on the bottom support member 3 are turned over the first folding plate 21, and then the two turning and stirring plates 33 are correspondingly clamped and blocked with the two first baffle plates 23, and then the turning and stirring plates 33 are clamped and blocked with the two second baffle plates 32, so that the folding member 2 and the bottom support member 3 form an interleaved connection manner. Then, the two inner turning plates 22 are turned up and inserted into the connection part between the first folding plate 21 and the second folding plate 31, so that the two inner turning plates 22 are turned up above the second folding plate 31. Then, the two bottom plates 4 are put down and pressed on the folding member 2 and the bottom support member 3, and the two bottom plates 4 are adhered to each other through double-sided tape;
