Description

Technical Field

[0001] The utility model relates to the technical field of paper boxes, in particular to a pressure-resistant corrugated paper box. Background Art

[0002] Corrugated boxes are rigid paper containers made of corrugated cardboard. They are very practical packaging products with a wide range of applications, such as food, beverages, home appliances, furniture, medicine and other industries. Corrugated boxes have many advantages, such as lightness, firmness, beauty, easy printing, environmental protection, etc. They can protect goods, facilitate storage and transportation, and beautify and promote goods. In addition, corrugated paper boxes have good processing performance and can be made into paper boxes of various shapes and sizes through processes such as die-cutting, creasing, nailing or gluing to meet the packaging needs of different commodities. However, existing corrugated paper boxes are usually sealed with tape when closed, which makes the corrugated paper boxes easily deformed under pressure at the joints of the seals. The pressure resistance is not strong, which can easily cause damage to the items in the corrugated paper boxes. At the same time, when opening the corrugated paper boxes, the tape needs to be peeled off, which can easily damage the corrugated cardboard and make it impossible to reuse the corrugated paper boxes. In addition, the corrugated paper boxes are reinforced with a supporting structure, which needs to be fixed inside the corrugated paper boxes. When the corrugated paper boxes are damaged, the supporting structure will also be unusable, which increases the cost of use and has certain disadvantages during use.

[0003] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] like Figure 1-5As shown, the present embodiment provides a pressure-resistant corrugated paper box, including a paper box body 1, a first corrugated paper cover plate 2 and a second corrugated paper cover plate 3, the first corrugated paper cover plate 2 and the second corrugated paper cover plate 3 are both rotatably mounted on the paper box body 1, one end of the first corrugated paper cover plate 2 is fixedly connected to one end of the second corrugated paper cover plate 3 through a reinforced elastic snap-fit ​​assembly 4, when in use, the reinforced elastic snap-fit ​​assembly 4 is controlled to fix the first corrugated paper cover plate 2 and the second corrugated paper cover plate 3 in connection, so that the paper box body 1 is in a closed state, and the first corrugated paper cover plate 2 and the second corrugated paper cover plate 3 can be fixedly connected by replacing the traditional adhesive tape bonding method. The connection between the first corrugated cardboard cover plate 2 and the second corrugated cardboard cover plate 3 is reinforced to improve the pressure resistance of the carton box body 1. Positioning blocks 5 are fixedly bonded on the inner walls of the first corrugated cardboard cover plate 2 and the second corrugated cardboard cover plate 3. A cross-shaped reinforcement block 6 is sleeved on the positioning block 5, and the cross-shaped reinforcement block 6 is fixed to the positioning block 5 through a self-locking connection component 7. When in use, the cross-shaped reinforcement block 6 reinforces the first corrugated cardboard cover plate 2 and the second corrugated cardboard cover plate 3, so that the first corrugated cardboard cover plate 2 and the second corrugated cardboard cover plate 3 are not easily deformed by pressure. At the same time, the self-locking connection component 7 is controlled to facilitate the removal of the cross-shaped reinforcement block 6 from the positioning block 5, so that the cross-shaped reinforcement block 6 can be reused.

[0022] The reinforced elastic clamping assembly 4 includes a first connecting block 401 and a second connecting block 402, which are respectively fixedly installed on the first corrugated cardboard cover plate 2 and the second corrugated cardboard cover plate 3. The first connecting block 401 is provided with an embedded card slot, and the second connecting block 402 is movably clamped in the embedded card slot. Square sliding holes are provided on the inner walls at both ends of the embedded card slot. A positioning block 403 is slidably clamped in the square sliding hole, and the positioning block 403 is elastically connected to the inner wall of one end of the square sliding hole through a first self-locking spring 404. Positioning clamp heads 405 are fixedly installed at both ends of the second connecting block 402, and the positioning clamp heads 405 are located below the positioning block 403. A toggle block 406 is fixedly installed on the top of the positioning block 403, and the toggle block 406 is slidably clamped in the yielding through hole provided on the first connecting block 401 to clamp the second connecting block 402. When in the embedded card slot, the positioning card head 405 squeezes the positioning stop block 403, causing the positioning stop block 403 to slide in the square sliding hole and squeeze the first self-locking spring 404. When the positioning card head 405 moves below the positioning stop block 403, the positioning stop block 403 automatically pops out under the action of the first self-locking spring 404, thereby limiting the positioning card head 405, so as to fix the second connecting block 402 in the embedded card slot and close the carton box 1, and control the toggle block 406 to make the positioning stop block 403 slide in the square sliding hole, so that the positioning stop block 403 moves to one side of the positioning card head 405, so as to remove the second connecting block 402 from the embedded card slot and open the carton box 1. It is flexible and convenient to use, and also solves the problem that the traditional carton box 1 is easily damaged by closing it with tape.

[0023] When the locking cam 706 is in the unlocking state, the locking cam 703 is locked and the locking cam 708 is locked.
