Detailed Description

Specific embodiments of the present utility model are described in further detail below. It should be understood that the description herein of the embodiments of the utility model is not intended to limit the scope of the utility model.

Fig. 1 is a schematic structural diagram of a buckle-type glue-free carton according to the present utility model. The eye-splice type glue-free paper box comprises a box body 10, four outer shaking covers 11 which are respectively connected with two ends of the box body 10, and four inner shaking covers 12 which are respectively connected with two ends of the box body 10. It is conceivable that the plug-in glue-free carton further comprises some other functional modules, such as a sticking head, a cover, a logo, etc., which are known to those skilled in the art and will not be described here again.

The box 10 may be an accommodating space with two open ends after assembly, and includes a front plate 101, two end plates 102 respectively connected to two sides of the front plate 101, and a rear plate 103 connected to the other side of the two end plates 102. The front plate 101 and the rear plate 103 have the same length and width. It is conceivable that the front plate 101 and the rear plate 103 may be connected by a glue head, and the fixing manner may be glue, nails, or the like, which are the prior art and are not described herein. In addition, the front plate 101 and the rear plate 103 should be the same size. The dimensions of the end plate 102 and the front and rear plates 101 and 103 should be designed according to practical needs. The case 10 may be made of corrugated board material to increase the strength and shock resistance of the carton, so that the case 10 has the characteristics of light weight, high structural strength and high buffering capacity.

Of the four outer caps 11, two outer caps 11 are respectively connected to both ends of the front plate 101, and the other two outer caps 11 are respectively connected to both ends of the rear plate 103. The two outer swing covers 11 located on the same side of the case 10 and oriented in different directions can be folded and overlapped on a plane perpendicular to the front plate 101 and the end plate 102, so as to complete the cover closing, as shown in fig. 2. The width of the outer swing cover 11 may be one half of the inner swing cover 12. The outer swing cover 11 includes one outer swing cover body 111, two insertion holes 112 provided at intervals on the outer swing cover body 111, and an indentation 113 parallel to the arrangement direction of the front plate 101 and the rear plate 103 and penetrating through the entire outer swing cover 11.

The shape of the outer swing cover 11 may be rectangular. The outer swing cover body 111 may cover the case 10, so as to cover and protect the load in the case 10.

The shape of the insertion opening 122 is a prolate square, the two insertion openings 112 are arranged along the arrangement direction of the end plate 102, and the insertion openings 12 are equidistantly disposed on the outer swing cover 11 located on the same side of the box 10 and having different orientations, so that when the outer swing cover 11 is covered on the cavity of the box 10, a large insertion opening can be formed and assembled by plugging with a below-described fastening component 1222, which will be described in detail below.

The indentation 113 is disposed at a middle position of the outer swing cover 11 in a width direction, and is used for bending the outer swing cover 11, controlling a distance between the sockets 112, and facilitating disassembly and assembly of the inner swing cover and the outer swing cover. It is conceivable that the position where the indentations 113 are provided may vary depending on the actual situation, such as the length of the outer swing cover 11.

Of the four inner swing covers 11, two ends of the end plate 102 are connected to two inner swing covers 12, respectively. The inner swing cover 12 includes an inner swing cover body 121 and an insert swing cover 122 cut from the inner swing cover body 121 and connected to the end plate 102 in a reversible manner.

The inner swing cover body 121 may have a rectangular shape. The inner swing cover 12 on the same side of the box 10 cannot completely cover the two end planes of the carton 10, and of course, the area occupied by the inner swing cover 12 on the two end opening planes of the box 10 can be changed according to actual needs, such as bearing capacity.

The insert swing cover 122 includes a receiving member 1221 coupled to the end plate 102 and a snap member 1222 coupled to the receiving member 1221.

The receiving member 1221 is configured to adjust a position of the locking member 1222 after the outer swing cover 11 and the inner swing cover 12 are closed, and fix the locking member 1222 in the socket 112, with a connection shaft with the end plate 102 as a tilting shaft. The receiving member 1221 may have a cut-round shape. It is of course conceivable that the receiving member 1221 may have other shapes. In this embodiment, the central angle of the receiving member 1221 is greater than 180 degrees, and the area and size of the receiving structure 1221 may be changed according to the actual situation, such as the length of the inner swing cover 12. Because the shape of the receiving member 1221 is a cut-circle, the shape lines of the receiving member 1221 at two sides outside the overlapping portion are arc lines, so that a gap is left between the receiving member 1221 and the clamping member 1222, and a gap is left for deformation of the clamping member 1222 when the clamping member 1222 is inserted into the socket 112, so that the clamping member 1222 can be inserted into the large socket more conveniently.

The clamping component 1222 is rectangular, the length of the clamping component 1222 is longer than the overlapping length of the inner swing cover 12, the clamping component 1222 is used for buckling the socket 112 in the box body 10, preventing the insert swing cover 122 from sliding out of the socket 112, and fixedly connecting the clamping component 1222 and the socket 112, and the inner swing cover 12 and the outer swing cover 11. The shortest distance between the clamping component 1222 and the inner swing cover 12 connected with the insertion swing cover 122 is equal to the shortest distance between the socket 112 and the inner swing cover 12. The snap fit member 1222 is connected to the receiving member 1221 at a distal end from the endplate 102. In this embodiment, because the carton is a buckle-type carton, the central axes of the snap-in member 1222 and the large receptacle are on the same line when the lid is closed. Preferably, the lengths of the sockets are consistent, the symmetry axes of the clamping component 1222 and the receiving component 1221 are lines passing through the center of the receiving component 1222 and perpendicular to the end plate 102, so that the moment arm of the inserted swing cover 122 is the same as that of the outer swing cover 11 on the same side of the box 10, and when the outer swing cover 11 receives the same gravity, the force of the inserted swing cover 122 received by the outer swing cover 11 on the same side of the box is the same, thereby enhancing the stability and service life of the carton structure.

The tape-free mounting process of the eye-splice tape-free case is as follows, the inserting swing cover 122 is separated from the inner swing cover 12, the inner swing cover 12 is closed, and the outer swing cover 11 is bent along the indentation 13, so as to provide a gap for inserting the clamping component 1222. The clamping component 1222 is aligned to the two sockets 112, and then force is applied to the indentations 113, so that the distance between the outer shake covers 11 is gradually shortened to finish closing, and the clamping component 1222 is successfully fixed in the large socket formed after the outer shake covers 11 are combined, namely, the fixation is finished.

Compared with the prior art, the plug-in buckle type adhesive-free carton provided by the utility model has the advantages that the plug 112 is arranged, and the shaking cover 122 is inserted with an indentation for adhesive-free carton sealing. The sockets at the same end of the case 10 may be combined to form a large socket when the case is closed, so that the two outer swing covers 11 may be fixed at the same time by the one insertion swing cover 122, and the installation is more convenient. The large socket and the inserted swing cover 122 are in axisymmetric patterns, and when the cover is closed, the central axes of the large socket and the inserted swing cover 122 are all on the straight line after the outer swing cover 11 is overlapped, so that the force from the outer swing plate 11 received by the inserted swing cover 122 is the same while the outer swing cover receives the same weight, and the strength of the carton is improved. The indentation 113 is used for bending the outer swinging cover 11 which is difficult to bend, and the distance between the inserting holes 112 can be controlled according to the bending radian of the outer swinging cover 11, so that the clamping component 1222 can be conveniently installed and inserted into a large inserting hole. The receiving member 1221 is cut round, and a space between the receiving member 1221 and the card and the member 1222 is provided for deformation generated when the card-engaging member 1222 is mounted. The part of the receiving member 1221 longer than the socket 112 is used to lock the socket 112 in the box, so as to prevent the insert swing cover 122 from sliding out of the socket 112, and enhance the stability of the structure. Meanwhile, when articles are placed in the eye-splice type adhesive-free paper box, the weight of the placed articles can enable the inner swing cover 12 to be pressed down, so that the clamping part 1222 and the outer swing cover 11 can be clamped tightly, the structural strength is improved, and the bottom of the paper box is prevented from being damaged.

The above is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model, and any modifications, equivalent substitutions or improvements within the spirit of the present utility model are intended to be covered by the claims of the present utility model.
