Description

Technical Field

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

[0002] As the name suggests, packaging boxes are boxes used to package products. They can be classified by material, such as paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated packaging boxes, etc. Functions of packaging boxes: ensuring the safety of products during transportation and improving the grade of products.

[0003] In order to improve the appearance and durability of traditional packaging boxes, corrugated cardboard is mostly used for production. Corrugated paper has the characteristics of low cost, light weight, easy processing, high strength, good printing adaptability, and convenient storage and transportation. Corrugated cardboard has good printing adaptability and can be printed on the cardboard according to customer needs, thereby improving the appearance of the packaging box. It can protect the items during transportation and prevent the items from being damaged by bumps during transportation.

[0004] However, when a packaging box made of corrugated paper is used in a humid environment, it is impossible to reduce the impact of humid air on the packaging box, thereby failing to reduce the phenomenon that the packaging box absorbs humid air and becomes soft and deformed, which easily affects the service life of the packaging box and is difficult to improve the moisture-proof effect of the packaging box. Utility Model Content

[0005] The utility model aims to provide a pressure-resistant and moisture-proof packaging box in view of the defects and shortcomings of the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pressure-resistant and moisture-proof packaging box, comprising a lower box body with a accommodating cavity, an upper cover arranged at the upper end of the lower box body, and also comprising at least one placement ring hole opened on the side end surface of the lower box body and connected to the accommodating cavity, a mounting sleeve column arranged on the lower box body, located in the placement ring hole and matching with the placement ring hole gap, an inner limit plate arranged at one end of the mounting sleeve column and located in the accommodating cavity, a storage cavity opened on the mounting sleeve column, an outer limit block detachably arranged on the other end of the mounting sleeve column, an outer limit net arranged on the outer limit block for allowing gas to flow to the storage cavity, a desiccant filled and arranged on the mounting sleeve column in the storage cavity for absorbing humid air when gas flows to the storage cavity, and at least one avoidance opening opened on the side end surface of the upper cover and matching with the mounting sleeve column gap for engaging with the mounting sleeve column when the upper cover and the lower box body are matched.

[0007] Further effect: the outer limit block is threadedly connected to the other end of the mounting sleeve.

[0008] An inner limiting net for allowing gas to flow into the accommodating cavity and preventing the desiccant from leaking into the accommodating cavity is arranged at one end of the installation sleeve column and is located in the storage inner cavity.

[0009] Further effect: the desiccant is activated carbon particles or calcium chloride particles or quicklime blocks.

[0010] Further effect: the bottom surface of the upper cover is provided with a pressure-resistant plate for improving the pressure-resistant effect of the upper cover.

[0011] Further effect: the compression-resistant plate is an expandable polystyrene plate.

[0012] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when the packaging box made of corrugated paper is used in a humid environment, the gas is circulated to the storage cavity through the external limiting net, and then the humid air is absorbed by the desiccant, thereby reducing the environmental humidity around the lower box body and reducing the impact of humid air on the packaging box, thereby reducing the phenomenon of the packaging box absorbing humid air and becoming soft and deformed, which is not easy to affect the service life of the packaging box and can improve the moisture-proof effect of the packaging box.

[0013] Further effect: when the upper cover and the lower box body are matched, the avoidance opening is engaged with the installation sleeve, which will not affect the sealing process of the upper cover and the lower box body.

[0014] Further effect: The external limit net can prevent the desiccant from leaking outwards.

[0015] Further effect: when the upper cover and the lower box body are sealed together, the avoidance opening of the upper cover is located in the gap between the outer limit block and the side end face of the lower box body. By rotating the outer limit block, the end of the upper cover can be approached on the mounting sleeve until the side end face of the outer limit block is squeezed with the side end face of the upper cover, thereby fixing the upper cover on the lower box body.

[0016] Further effect: after the desiccant is used to absorb moist air for a period of time, it can be removed from the installation sleeve by rotating the outer limit block, and then the installation sleeve is removed from the placement ring hole, and then the desiccant is replaced, thereby maintaining the desiccant's absorption effect on moist air.

DETAILED DESCRIPTION

[0022] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0023] See also Figures 1 to 3 As shown, the technical solution adopted in this specific embodiment is: a pressure-resistant and moisture-proof packaging box, including a lower box body 2 with a receiving cavity 1, an upper cover 3 arranged at the upper end of the lower box body 2, and also including at least one placement ring hole 4 opened on the side end surface of the lower box body 2 and connected to the receiving cavity 1, a mounting sleeve 5 arranged on the lower box body 2 and located in the placement ring hole 4 and with a clearance fit with the placement ring hole 4, an inner limit plate 6 arranged at one end of the mounting sleeve 5 and located in the receiving cavity 1, and a mounting sleeve 5 opened on the mounting sleeve 5. The storage cavity 7, the outer limit block 8 detachably arranged on the other end of the mounting sleeve column 5, the outer limit net 9 arranged on the outer limit block 8 for allowing gas to flow to the storage cavity 7, the desiccant 10 filled and arranged on the mounting sleeve column 5 and located in the storage cavity 7 for absorbing humid air when the gas flows to the storage cavity 7, and at least one avoidance opening 11 opened on the side end surface of the upper cover 3 and having a clearance fit with the mounting sleeve column 5 for engaging with the mounting sleeve column 5 when the upper cover 3 is matched with the lower box body 2. The number of the placement ring hole 4, the mounting sleeve column 5, and the avoidance opening 11 can also be two or three, all of which are arranged on the side of the lower box body 2. When the number of the placement ring hole 4, the mounting sleeve column 5, and the avoidance opening 11 is two, they can be symmetrically arranged on the front and rear sides of the lower box body 2, and cooperate with the inner limit net 12 to form the phenomenon of air circulation, and absorb the humid air through the desiccant 10 during circulation, so as to further improve the moisture-proof effect.

[0024] The outer limit block 8 is threadedly connected to the other end of the mounting sleeve 5 .

[0025] An inner limiting net 12 for allowing gas to flow into the accommodating chamber 1 and preventing the desiccant 10 from leaking into the accommodating chamber 1 is disposed at one end of the mounting sleeve 5 and located in the storage inner chamber 7 .

[0026] The desiccant 10 is activated carbon particles or calcium chloride particles or quicklime blocks. Activated carbon has a certain hygroscopicity due to its porous structure. When activated carbon particles are exposed to a humid environment, they will absorb moisture from the surrounding environment. The calcium chloride granular dehumidifier mainly absorbs moisture in the air and fixes it on the surface of the particles through the characteristics of the adsorbent. Calcium chloride is a highly hygroscopic substance. When it comes into contact with water, it will quickly absorb moisture and form calcium chloride hydrate. Granular calcium oxide quicklime is a desiccant made by mixing calcium oxide with water, also known as quicklime granules. Granular calcium oxide quicklime has strong hygroscopicity and easily absorbs moisture in the air. At the same time, quicklime reacts with water to produce calcium hydroxide, which can absorb and dry.

[0027] The bottom surface of the upper cover 3 is provided with a pressure-resistant plate 13 for improving the pressure-resistant effect of the upper cover 3 .

[0028] The anti-compression plate 13 is an expandable polystyrene plate. Expandable polystyrene (EPS) plate is a hard and porous material, which has excellent heat insulation, shock absorption and high compressive strength. The anti-compression plate 13 can also be an acrylic plate.

[0029] The working principle of the utility model is as follows: when the packaging box made of corrugated paper is used in a humid environment, the gas is supplied to the storage cavity 7 through the outer limiting net 9, and then the humid air is absorbed by the desiccant 10, so as to reduce the environmental humidity around the lower box body 2 and reduce the influence of the humid air on the packaging box, thereby reducing the phenomenon that the packaging box becomes soft and deformed due to absorbing humid air, which is not easy to affect the service life of the packaging box and can improve the moisture-proof effect of the packaging box; when the upper cover 3 and the lower box body 2 are matched, the avoidance opening 11 is engaged with the installation sleeve 5, which will not affect the sealing process of the upper cover 3 and the lower box body 2; the outer limiting net 9 can prevent the desiccant 10 from flowing to External leakage phenomenon; when the upper cover 3 and the lower box body 2 are sealed together, the avoidance opening 11 of the upper cover 3 is located in the gap between the outer limit block 8 and the side end face of the lower box body 2, and the outer limit block 8 can be rotated to approach the end of the upper cover 3 on the mounting sleeve 5 until the side end face of the outer limit block 8 is squeezed with the side end face of the upper cover 3, so that the upper cover 3 can be fixed on the lower box body 2; when the desiccant 10 is used to absorb the humid air for a period of time, it can be removed from the mounting sleeve 5 by rotating the outer limit block 8, and then the mounting sleeve 5 is taken out of the placement ring hole 4, and then the desiccant 10 is replaced, so as to maintain the absorption effect of the desiccant 10 on the humid air.
