Description

Thermal insulation bag with good sealing performance Technical Field The utility model relates to the technical field of heat preservation bags, in particular to a heat preservation bag with good sealing performance. Background The thermal insulation package is the important equipment of dress delivery article, especially for outdoor fan, and when outdoor far away, runs into rainy day weather, if the rainwater gets into in the thermal insulation package will soak the article in the thermal insulation package, consequently has appeared waterproof thermal insulation package on the market. For example, the patent with publication number CN 213800951U discloses a portable packing bag that sealing effect is good, through being provided with the sealing strip in the inside of bag body for the leakproofness is strengthened, and article is placed in the inside back of bag body, carries out mutual extrusion with sealing strip and seal groove and carries out the coincidence, makes the bag body in obtain sealedly, then presses the face of colluding of connection piece one end and the rough surface on double-deck edge to paste, makes the bag body obtain double seal, thereby realizes strengthening the leakproofness. The problem with the above technique is that when the user takes the articles in the bag, the sealing strip needs to be opened, and if the user forgets to reseal the sealing strip after taking the articles, rainwater can enter from the opening of the bag to saturate the articles in the bag. Therefore, the heat preservation bag with good sealing performance is provided to solve the technical problems. Disclosure of utility model In order to solve the technical problems, the utility model aims to provide the thermal insulation bag with good sealing performance, and the thermal insulation bag can also have the effect of sealing the thermal insulation bag opening when a user forgets to manually close the thermal insulation bag opening. The utility model adopts the technical scheme that the thermal insulation bag with the good sealing performance comprises a bag body with an upper opening, wherein the bag body comprises a front end part and a rear end part, sealing assemblies are arranged on the front end part and the rear end part and are used for sealing the opening of the bag body, elastic strips are arranged on the front end part and the rear end part relatively, the elastic strips are positioned below the sealing assemblies, the length of the elastic strips is consistent with the length of the opening of the bag body, and the elastic strips can automatically rebound and straighten after being bent, so that the front end part and the rear end part are mutually abutted and seal the opening of the bag body. As a further improvement of the above technical solution, the sealing assembly includes a zipper engaged with each other. As a further improvement of the technical scheme, the sealing assembly comprises a sealing strip and a sealing groove which are mutually clamped. As a further improvement of the technical scheme, the upper end of the bag body is provided with a folding part, and the upper end of the bag body can be bent and folded along the folding part, so that the opening of the bag body faces downwards. As a further improvement of the above technical solution, the folding portion includes an upper end portion and a lower end portion, a folding line is provided between the upper end portion and the lower end portion, magnetic members are disposed on the upper end portion and the lower end portion, the upper end portion can be folded and bent along the folding line, and the upper end portion can be abutted to the lower end portion through the magnetic members. As a further improvement of the above technical solution, the magnetic member is disposed at a front end portion or the magnetic member is disposed at a rear end portion. As a further improvement of the technical scheme, the outer surface of the bag body is provided with a strap. The bag has the advantages that when a user needs to take articles in the bag, the sealing assembly is required to be unlocked, the elastic strip is simultaneously broken off to separate the front end part from the rear end part, the opening of the bag body can be opened, and when the user forgets to close the sealing assembly when taking the articles in the bag, the elastic strip can drive the front end part and the rear end part to approach and abut against each other through the elasticity of the elastic strip, so that the opening of the bag body is sealed, and rainwater can be prevented from entering.
