Description
Technical Field
The invention relates to the technical field of cold-chain logistics heat preservation, in particular to a passive double-box linkage type portable heat preservation box.
Background
In the current cold-chain logistics transportation, the insulation boxes play an increasingly important role, the quality of the insulation boxes is directly related to the quality of transported articles, and the insulation boxes are used in the cold-chain transportation of more and more articles.
In cold chain transportation, different medicines have different temperature intervals and need to be strictly controlled; different fresh vegetables and fruits also have more proper temperature requirements so as to ensure less nutrition loss; in extremely cold regions such as northeast, fresh vegetables and the like still face the problem of frostbite, the heat insulation box is needed to keep warm, and the like, so that the function of the heat insulation box is improved from ensuring that commodities are not damaged to ensuring the better quality of the commodities. How to make the insulation can keep warm for a longer time and provide suitable temperature ranges for different commodities, and how to carry the insulation can easily becomes the most important requirement for the insulation can, and is also the key point of the technical development of the insulation can.
With the rapid development of e-commerce, the environmental pressure brought by the massive amount of packaging is becoming the focus of public attention, and for cold chain packaging, the same is faced with this aspect. In order to be more environment-friendly, a fresh 'green recycled air' is scraped in the whole logistics industry at present, and the disposable insulation can is upgraded to a recyclable insulation can. Many large-scale fresh food electricity business platforms and logistics service providers have started to use recyclable heat preservation boxes and cold storage plates, and are popularized to the end distribution link between a warehouse and a client through the turnover link between the warehouse and the client.
All links and all processes of the cold-chain logistics service always follow the principle of integrated operation, namely integration of operation links of goods taking, box selecting, ice plate configuration, box sealing, transportation, turnover, distribution, temperature measurement and the like, so that the problem of coordination and matching among the links and the processes of the cold-chain logistics operation is integrally solved, and an efficient and reasonable integrated service and an integrated solution are provided.
In the existing market, the common turnover insulation boxes for cold chain transportation are various in types, so that people are not free, for example, an active insulation box needs to be charged or plugged with a power supply, and a cold source is provided by the work of a compressor; there are also many passive incubators, which are also the most widely distributed incubators in the current market, including rotational molding incubators, injection molding incubators, blow molding incubators, and foaming incubators, but these incubators have different disadvantages:
(1) an active incubator. Charging or plugging is required, temperature is easy to control, but the temperature can be applied for a short time, and maintenance of a power supply and a compressor requires certain cost. The overall cost is much higher than a passive incubator for the same volume.
(2) Rotational molding of the insulation can: because the outer layer is made of plastic and mostly made of LDPE or LLDPE, from the heat conduction perspective, the heat conduction coefficient of the materials is higher, the heat conduction is too fast, and the heat preservation is poorer; from intensity, though resistant falling is crashproof, but is heavier, because the reason of technology leads to the frid ventilation structure and places the structure and do not make well, and these can lead to the air current circulation not too smooth and easy, secondly if the frid is not well placed, directly lead to the preparation operating time overlength before the transportation, influence ageing and heat preservation effect.
(3) Injection molding and blow molding of the insulation can: both the molds have high cost, the outer layer is made of plastics, such as ABS, PE or PS, and the like, and from the perspective of conduction, the materials have large heat conductivity coefficient, are conducted too fast, and are easy to bridge (namely, the cold air in the box is easily conducted too fast), so that the heat preservation effect in the box is poor. Due to the process, the capacities of the two heat preservation boxes in the aspect of being impacted are poor, the whole weight is heavier, meanwhile, the ventilation structure and the placement structure of the ice plates in the boxes are not easy to manufacture, airflow circulation is not smooth, and if the ice plates are not placed well, the preparation time before transportation is too long, and the aging and heat preservation effects are affected.
(4) Foaming type heat preservation box: the most of the insulation boxes in the market are pure PU foaming insulation boxes, single-box EPP insulation boxes and EPS insulation boxes.
Although the capacity of the PU foaming thermal insulation box is good, the materials and the process determine that the ventilation structure inside and the ice board placing structure are not easy to manufacture, which can directly affect the problem in the aspect of operation, and the pure PU foaming box has weak capacity in the aspect of crashworthiness and low price cost.
The single-box EPP heat preservation box is light in weight; the strength of the single-box EPP is low, and the airflow with high expansion ratio can flow, but the single-box EPP has poor heat-insulating performance.
Although the EPS insulation can is light in weight, the impact resistance is poor, the insulation effect is general, and the EPS insulation can is usually used as a disposable packing material.
The cold chain logistics transportation system is applied to actual cold chain transportation, and relates to a series of processes such as goods taking, box selecting, ice plate configuration, box sealing, transportation, turnover, distribution and temperature measurement, so that the weight, temperature control, space planning, operation, cost, environmental protection, energy conservation and the like are factors which need to be considered, and the problems that the defects of various common insulation boxes in cold chain logistics transportation are solved reliably and better, the operation efficiency in the cold chain refrigeration process is improved, the insulation box performance is improved, the quality of transported goods is protected, the labor cost, the aging cost, the insulation box cost, the operation cost of transportation enterprises and the like are reduced are the problems to be solved.
Disclosure of Invention
The invention aims to provide a passive double-box linkage type portable insulation box, and the application aims to solve the technical problem of how to increase the application space of the box body, wherein the insulation box is easy to operate, light, collision-resistant, firm and stable in assembly, good in insulation effect and capable of increasing the maximum efficiency.
In order to achieve the purpose, the invention provides the following technical scheme:
a passive double-box linkage type portable insulation box comprises an outer box body, an outer box cover, an inner box body and an inner box cover, wherein the outer box cover is covered on an upper end opening of the outer box body, the inner box cover is covered on an upper end opening of the inner box body, a group of positioning convex columns are arranged on the inner side wall of the outer box body, positioning groove positions used for correspondingly matching the positioning convex columns are formed in the outer side wall of the inner box body, the inner box body is embedded in the outer box body in a matching mode, insulation boards located in the positioning groove positions are arranged between the positioning convex columns of each group, an insulation groove is formed in the inner bottom wall of the outer box body, and the insulation boards are also embedded in the insulation groove;
besides being matched with the inner box body, the positioning convex columns on the inner wall of the outer box body can be used as slot positions of the ice row plates of the outer box body when the inner box body and the outer box body are detached for use, and the insulation plates are replaced by the ice row plates.
