[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0022] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a ventilated carton with air holes of the utility model comprises a carton 1, wherein both side surfaces of the carton 1 are provided with a plurality of air holes, support frames 2 are inserted into the air holes, outer end surfaces of the support frames 2 are bent outward to form a limiting portion 3 of a frame-type structure, the inner side surface of the limiting portion 3 is in contact with the outer side surface of the carton 1, and the inner end surfaces of the support frame 2 are respectively installed with a bottom plate 9 and a top plate 4, and slots are formed between the bottom plate 9 and the carton 1 and between the top plate 4 and the carton 1, top frames 6 are inserted into the upper multiple slots, and bottom frames 8 are inserted into the lower multiple slots.

[0024] In this embodiment, the lower end of the top plate 4 is connected to the inner end surface of the support frame 2 through a hinge, and the upper end of the top plate 4 is installed on the inner end surface of the support frame 2. The outer surface of the top plate 4 is provided with a positioning groove 12, and the inner side surface of the top frame 6 protrudes at the location corresponding to the positioning groove 12 to form a positioning portion 5, and the positioning portion 5 is inserted into the positioning groove 12;

[0025] Among them, after the top frame moves upward, the positioning part can be moved out of the positioning groove. After losing the limit of the positioning part, the top plate can rotate downward with the hinge as the center, so that the upper part of the support frame can be moved out of the air hole, and the disassembly and replacement of the support frame has been completed.

[0026] In this embodiment, the cross sections of the positioning groove 12 and the positioning portion 5 are both arranged in a trapezoidal structure, and the top plate can be positioned by the positioning groove and the positioning portion of the trapezoidal structure.

[0027] In this embodiment, grooves 11 are provided at both ends of the top frame 6 in the width direction, and support plates 7 are placed in the longitudinal grooves 11 .

[0028] In this embodiment, the outer side surfaces of the top frame 6 and the bottom frame 8 are in contact with the inner side surface of the carton 1, increasing the contact area between the top frame and the bottom frame and the carton to ensure stability after placement.

[0029] In this embodiment, the support frame 2, the limiting portion 3 and the bottom plate 9 are all integrally injection-molded from a plastic material, and the top plate 4 is made of a plastic material, which reduces the cost and weight, and the plastic also has a strong strength.

[0030] In this embodiment, the top surface of the top frame 6 is flush with the open end surface of the carton 1; the top surface of the support plate 7 is flush with the top surface of the top frame 6, so that after the cover plate is closed, the inner side surface of the cover plate can contact the open end surface of the top frame and the top surface of the support plate, thereby increasing the contact area.

[0031] During assembly, first put the bottom frame into the carton, then rotate the top plate downward with the hinge as the center. After the top plate is lower than the top surface of the support frame, the bottom plate at the lower end of the support frame can be inserted into the air hole first. After the support frame is fully inserted, the inner side of the limit part can contact the outer side of the carton, and the slot below can be put on the bottom frame.

[0032] After the above is completed, the top plate can be lifted. After the top plate is fully lifted, the top frame can be inserted into the slot formed between the top plate and the carton, and the positioning part is inserted into the slot of the top plate. The top plate can be positioned by the positioning part so that the top plate cannot rotate outward. The inner side of the support frame can be positioned by the top plate and the bottom plate, so that the support frame is prevented from falling out of the air hole, thereby increasing the stability of the installation.

[0033] Among them, the vertical support strength of the carton is increased by the support frame, while the lateral support strength of the carton is increased by the top frame and the bottom frame;

[0034] When the carton needs to be covered, the support plate can be placed in the groove. After the cover plate on the carton is closed, the inner side of the cover plate can rest against the support plate, providing support for the middle of the cover plate and avoiding collapse in the middle of the cover plate.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
