[0001] This application relates to the technical field of packaging cartons, and in particular to a new type of cardboard packaging box. Background Art

[0002] Carton packaging refers to the packaging of products using paper boxes during the circulation process to protect products, facilitate storage and transportation, and promote sales. Carton packaging is the most widely used packaging method. Different from wooden box packaging, woven bag packaging, cloth bag packaging, and plastic box packaging, carton packaging has the characteristics of easy material acquisition, light weight, easy printing, easy design and molding, and low cost, and is widely used in the transportation packaging of goods.

[0003] Chinese Patent with Publication No. CN214777935U discloses a bottled water packaging box, which includes a front board, a rear board, a top board, and a bottom board. Top inclined boards are respectively connected to the sides of the front board and the rear board opposite to the bottom board. The top inclined board connected to the front board is connected with an adhesive flap. Outer swing covers are connected to the left and right sides of the top board and the bottom board, and inner swing covers are connected to the left and right sides of the front board and the rear board. The inner swing covers are divided into side inclined boards and inner boards.

[0004] The unfolded state of the carton is usually cut from a complete cardboard. During the cutting process of the above-mentioned carton, there is cardboard cutting space between the outer swing cover and the inner swing cover, and the cardboard cutting space between the outer swing cover and the inner swing cover cannot be used again for carton production, resulting in a low utilization rate of the cardboard, which has deficiencies. Summary of the Utility Model

[0005] In order to improve the utilization rate of cardboard, this application provides a new type of cardboard packaging box.

[0006] The new type of cardboard packaging box provided by this application adopts the following technical solutions:

[0007] A new type of cardboard packaging box includes multiple cardboard units. Connecting seats are arranged on the circumferential sides of the cardboard units. A fixing component is arranged between the connecting seats and the cardboard units. Fasteners are arranged between the connecting seats on adjacent two cardboard units.

[0008] By adopting the above technical solutions, workers cut out the cardboard of the required sizes for each face of the carton on a cardboard according to the design dimensions of the carton, and then install connecting seats on the circumferential sides of each cardboard unit through the fixing component. The connecting seats on adjacent two cardboard units are fixed through fasteners, so as to assemble a complete carton. Since the cross-section of the cut cardboard unit is usually rectangular, it is beneficial to reduce the generation of waste cardboard, thereby improving the utilization rate of the cardboard.

[0009] Optionally, the cardboard unit includes a front side plate, a rear side plate, a left side plate, a right side plate, a bottom plate, and a top plate, and a tear slit is provided on the top plate.

[0010] By adopting the above technical solution, it is convenient for the user to open the carton through the tear slit to take out the items inside the carton, and at the same time, it also reduces the possibility of the items inside the carton being replaced.

[0011] Optionally, the fastener includes a hook rod provided on the connecting seat, a hook head is provided on the hook rod, a fastening groove is provided on the connecting seat, and an anti - detachment block is provided in the fastening groove of the connecting seat, and the anti - detachment block is used to catch the hook head on another connecting seat.

[0012] By adopting the above technical solution, the worker brings the connecting seat on one cardboard unit close to the connecting seat on another cardboard unit. The hook rod on one connecting seat is inserted into the fastening groove on another connecting seat. Through the plastic deformation of the hook head, the hook head catches on the anti - detachment block on another connecting seat, thereby realizing the splicing and fixing of the two connecting seats, and thus splicing multiple cardboard units into a carton.

[0013] Optionally, the fixing component includes an insertion rod provided on the connecting seat. The insertion rod is used to pierce through the cardboard unit. An anti - detachment cone is provided on the insertion rod. The maximum diameter of the anti - detachment cone is greater than the diameter of the insertion rod, and the diameter of the anti - detachment cone gradually decreases along the direction from the connecting seat to the insertion rod. A clamping plate is provided on the side of the cardboard unit facing away from the connecting seat, and a conical hole for the anti - detachment cone to pass through is provided on the clamping plate.

[0014] By adopting the above technical solution, the worker first penetrates both sides of the cardboard unit through the insertion rod and the anti - detachment cone to fix the connecting seat on the cardboard unit. Then, the clamping plate is sleeved on the anti - detachment cone through the conical hole, so that the cardboard unit is clamped and fixed by the connecting seat and the clamping plate. During the process of the anti - detachment cone passing through the conical hole, the anti - detachment cone deforms, thereby preventing the clamping plate from detaching from the cardboard unit.

[0015] Optionally, the diameter of the conical hole gradually decreases along the direction from the connecting seat to the insertion rod.

[0016] By adopting the above technical solution, during the process of the anti - detachment cone piercing through the cardboard unit, the paper on the cardboard unit will bulge, and the bulging paper will be squeezed into the conical hole, which is beneficial to reducing the gap between the clamping plate and the cardboard unit and improving the stability of the mechanism between the cardboard units.

[0017] Optionally, the fixing component includes a fixing plate for clamping the cardboard unit. A clamping plate slot is formed in the connecting seat, and the cardboard unit is inserted into the clamping plate slot. A locking slot with a T-shaped cross-section is formed in the connecting seat. An insertion bar that is inserted and matched with the locking slot is arranged on the fixing plate. An anti-disengagement protrusion is arranged on the insertion bar, and the anti-disengagement protrusion is used for being stuck in the locking slot.

[0018] By adopting the above technical solution, the worker first inserts the cardboard unit into the clamping plate slot on the connecting seat, and then the worker inserts the insertion bar on the fixing plate into the locking slot on the connecting seat. During the insertion process of the insertion bar, the anti-disengagement protrusion deforms, and finally the anti-disengagement protrusion is stuck in the locking slot, so that the fixing plate clamps the cardboard unit on the connecting seat, facilitating the worker to fix the connecting seat on the cardboard unit.

[0019] Optionally, a positioning pin is arranged on one side of the clamping plate slot on the connecting seat facing the cardboard unit.

[0020] By adopting the above technical solution, the worker first obliquely inserts the cardboard unit into the clamping plate slot on the connecting seat, and then the worker rotates the angle of the cardboard unit so that the cardboard unit presses on the positioning pin, thereby realizing the preliminary fixation of the cardboard unit.

[0021] Optionally, a plurality of barbed protrusions are arranged on the fixing plate, and the barbed protrusions are used for piercing into the cardboard unit.

[0022] By adopting the above technical solution, during the process of inserting the insertion bar on the fixing plate into the locking slot, the barbed protrusions on the fixing plate gradually approach and finally pierce into the cardboard unit, further improving the strength of the mechanism between adjacent two cardboard units.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. According to the designed size of the carton, the worker cuts out the cardboard of the required sizes for each face of the carton on one cardboard, and then installs connecting seats on the circumferential side edges of each cardboard unit through the fixing component. The connecting seats on adjacent two cardboard units are fixed through fasteners, thereby assembling a complete carton. Since the cross-section of the cut cardboard unit is usually rectangular, it is beneficial to reduce the generation of waste cardboard, thus improving the utilization rate of the cardboard.

[0025] 2. The worker brings the connecting seat on one cardboard unit close to the connecting seat on another cardboard unit. The hook rod on one connecting seat is inserted into the fastening slot on another connecting seat. Through the plastic deformation of the hook block head, the hook block head is stuck on the anti-disengagement block on another connecting seat, thereby realizing the combined fixation of the two connecting seats, and thus splicing multiple cardboard units into a carton.

[0026] 3. The worker first inserts the cardboard unit into the clamping slot of the connection base, and then inserts the insert bar on the fixing plate into the locking slot of the connection base. During the insertion of the insert bar, the anti - detachment protrusion deforms, and finally the anti - detachment protrusion is stuck in the locking slot, so that the fixing plate clamps the cardboard unit on the connection base, facilitating the worker to fix the connection base on the cardboard unit.
