The utility model provides an improved heat preservation box, in which a flange is formed at the top of the upper edge of the box body and the flange is closed; the flange comprises at least two flange monomers; the upper end of each flange monomer is even; the upper end of the flange monomer is an arc top; and the flange monomer is an elastic material. Thus, the utility model breaks through the traditional structure of the heat preservation box, and the flange can be matched and clipped into the groove corresponding to the lower surface of the cover to form a curved contact surface; at least two flange monomers parallel to each other can form a plurality of curved contact surfaces, increase the number of sealing checkpoints between the flange and the groove of the cover, and the upper end of each flange monomer. Flattening ensures that each flange monomer and the groove of the cover are in contact at the same time. The arc-shaped top ensures that the flange monomer and the groove of the cover are more flexible and uniform. The flange monomer made of elastic material can be more closely connected with the groove of the cover, further enhancing the sealing effect of the contact between the cover and the main body of the box. Therefore, the utility model has strong sealing performance and has remarkable heat preservation effect.

一种改进型保温箱
本技术涉及保温装置领域,具体涉及一种改进型保温箱。
技术介绍
保温箱的结构已为公知,如中国技术专利CN201320025632.4公开一种海鲜保温箱,包括箱体和箱盖,所述的箱体设置有载物内腔,其特征在于,所述箱体的上端边缘处设置有箱体凸块,所述的箱盖下端面边缘处设置有箱盖凸块,且箱体和箱盖通过卡扣配合箱体凸块、箱盖凸块紧固连接,且所述的箱体和箱盖内部呈中空结构,所述箱体的载物内腔的下表面开设有一凹槽,且所述的凹槽上设置有贯穿箱体壁的排水通孔,所述的箱体高度和凹槽深度的比值为8-11。所述的凹槽置于箱体底部的中间,且和箱体的两相对箱壁连接。所述的排水通孔为一个,置于凹槽和箱体一侧壁的连接处,且排水通孔通过一橡胶塞密封。所述的箱体凸块和箱盖凸块为六对,且分别平均的置于箱体和箱盖的两侧边缘处。所述的箱体和箱盖之间还设置有密封条。所述箱体的载物内腔容量为150-180L。该技术与市场上其他保温箱的结构类似,在实际使用过程中,箱盖与箱体经常出现接触不紧,密封不良,进而严重影响保温效果的情况。鉴于此,本案专利技术人对上述问题进行深入研究,遂有本案产生。
