Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a heat-insulating plastic packaging box. Background Art

[0002] At present, in the field of cold chain transportation, many items such as medicines and food need to maintain a certain temperature or a certain temperature range for a certain period of time during storage, turnover and transportation. It is necessary to put the insulated items in insulated packaging boxes and transport the insulated packaging boxes together with the logistics of the items.

[0003] The existing thermal insulation packaging box has a simple structure and often only uses plastic foam to insulate the items, resulting in poor thermal insulation effect of the thermal insulation packaging box and easy damage. For some items with high storage temperature requirements, it cannot achieve a good preservation effect. The sealing method of the existing thermal insulation packaging box is often just a layer of cover plate directly covering the thermal insulation box. In this way, not only is it easy for external heat to enter the thermal insulation box through the gap, but the heat in the thermal insulation box is also easy to lose, resulting in low thermal insulation efficiency. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] like Figure 1-4 As shown, the utility model provides a heat-insulating plastic packaging box, comprising a box body 1, the box body 1 comprising a heat-insulating plate 101, an inert gas plate 102 and a shock-absorbing layer 103, and a top cover 3 is arranged above the box body 1;

[0032] The top cover 3 comprises an elastic rubber sleeve 301 , a sealing rubber buckle 302 and a second insulation board 303 , and a handle groove 4 is provided on the upper end surface of the top cover 3 .

[0033] Specifically, a handle body 6 is installed inside the handle groove 4, and a classification partition 5 is fixedly arranged inside the box body 1. The advantage is that a handle groove 4 is opened in the middle of the top of the top cover 3, and a handle body 6 is arranged inside the handle groove 4 through a hinge. The handle groove 4 on the top of the top cover 3 is convenient for storing the handle body 6, which saves space when the boxes 1 are stacked, and the handle body 6 is also convenient for users to move the boxes 1.

[0034] Specifically, a heat-insulating plate 101 is arranged in the inner wall of the box 1, and an inert gas plate 102 is fixedly arranged inside the box 1. The advantage is that the setting of the heat-insulating plate 101 can improve the heat-insulating capacity of the box 1, and the inert gas plate replaces the traditional method of using plastic heat-insulating foam and uses inert gas with low thermal conductivity for heat-insulating, which greatly improves the heat-insulating effect.

[0035] Specifically, a shock-absorbing layer 103 is fixedly arranged inside the box 1, and a card slot 104 is provided on the outer surface of the box 1. The advantage is that the shock-absorbing layer 103 is a polyurethane soft foam board structure. Since polyurethane foam material is often used as a heat-insulating material and the soft foam board structure is relatively soft, the heat-insulating effect of the box 1 is further improved while preventing shock and reducing pressure.

[0036] Embodiment 2:

[0037] like Figure 1-4 As shown, as an improvement on the previous embodiment. Specifically, elastic rubber sleeves 301 are bonded around the top of the top cover 3, and a second insulation board 303 is fixedly provided on the lower end surface of the top cover 3. The advantage is that the elastic rubber sleeve 301 can seal and cover the connection between the top cover 3 and the box body 1. Since the inert gas layer 102 is filled with inert gas, and the inert gas has a low thermal conductivity, it can reduce the loss of heat in the box body 1 to achieve the effect of heat preservation, and the second insulation board 303 can effectively prevent heat from entering or flowing out from the connection gap, further improving the heat preservation performance, while making the box body 1 more firmly sealed and improving the stability of the box body 1.

[0038] Specifically, four sealing rubber buckles 302 are fixedly arranged on the inner side of the top cover 3, and the sealing rubber buckles 302 are connected with the card slots 104. The advantage is that the four sealing rubber buckles 302 on the top cover 3 are connected with the card slots 104 on the box body 1, and the cooperation between the sealing rubber buckles 302 and the elastic rubber sleeve 301 greatly improves the sealing effect, and the setting of four sealing rubber buckles 302 further improves the sealing performance.

[0039] Specifically, the bottom of the box 1 is fixedly provided with supporting feet 2, and the bottom of the supporting feet 2 is provided with anti-skid pads. The advantage is that the bottom of the box 1 is fixedly provided with supporting feet 2, and the bottom of the supporting feet 2 is provided with anti-skid pads, so that the placement of the box 1 is more stable, and it is not easy to move during transportation, so as to avoid collision and damage of the items in the box 1.

[0040] Working principle: a handle groove 4 is provided in the middle of the top of the top cover 3, and a handle body 6 is provided inside the handle groove 4 through a hinge. The handle groove 4 on the top of the top cover 3 is convenient for storing the handle body 6, which saves space when stacking the boxes 1, and the handle body 6 is also convenient for the user to move the boxes 1. Support feet 2 are fixedly provided at the bottom of the boxes 1, and anti-slip pads are provided at the bottom of the support feet 2, so that the placement of the boxes 1 is more stable and not easy to move during transportation, thereby avoiding collision and damage of the items in the boxes 1. The setting of the insulation board 101 can improve the thermal insulation capacity of the boxes 1, and the inert gas board, instead of the traditional method of using plastic thermal insulation foam, uses inert gas with low thermal conductivity for insulation, which greatly improves the thermal insulation effect. The shock-absorbing layer 103 is a polyurethane soft foam board structure. Since polyurethane foam material is often used As a thermal insulation material and a relatively soft structure of the soft foam board, it can further improve the thermal insulation effect of the box body 1 while preventing shock and reducing pressure. The elastic rubber sleeve 301 can seal and cover the connection between the top cover 3 and the box body 1. Since the interior of the inert gas layer 102 is filled with inert gas, and the thermal conductivity of the inert gas is low, it can reduce the loss of heat in the box body 1 and achieve the thermal insulation effect. The second insulation board 303 can effectively prevent heat from entering or flowing out from the connection gap, further improving the thermal insulation performance, and at the same time making the box body 1 more firmly sealed and improving the stability of the box body 1. Finally, the four sealing rubber buckles 302 on the top cover 3 are connected to the corresponding slots 104 on the box body 1. The cooperation of the sealing rubber buckles 302 and the elastic rubber sleeve 301 greatly improves the sealing effect, and setting the number of sealing rubber buckles 302 to four further improves the sealing performance.
