[0018] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Examples, such as Figure 1-Figure 4 As shown: The utility model provides an easy-to-use insulation box, whose structure includes a box body 1 and a box cover 2 installed on the box body 1, wherein the box body 1 is installed on an electric vehicle or other location where installation is required through a mounting frame 3, and the box body 1 and the mounting frame 3 are detachably connected, and an unlocking structure for releasing the restriction on the box body 1 moving in the disengagement direction on the mounting frame 3 is provided on the mounting frame 3 or the box body 1, so a handle or a shoulder strap 4 is provided on the box body 1, so that the box body 1 can be disassembled after the restriction on the box body 1 moving in the disengagement direction on the mounting frame 3 is released through the unlocking structure, and can be conveniently carried by the handle or the shoulder strap 4 after being disassembled.

[0020] The mounting frame 3 includes a horizontally arranged cross frame 31 and a vertical frame 32 vertically arranged on the cross frame 31. The box body 1 is installed in the space between the vertical frame 32 and the cross frame 31. In this embodiment, the cross frame 31 and the vertical frame 32 are each provided with one, and the cross frame 31 is separated into two side spaces by the vertical frame 32. The box body 1 is provided with a plurality of cross frames 31 on the mounting frame 3. In this embodiment, two cross frames 31 are provided and are arranged in the space of the cross frames 31 on both sides of the vertical frame 32. In addition, an inclined bottom support plate 33 is provided on the outer edge of the cross frame 31. The bottom end of the bottom support plate 33 is connected to the cross frame 31 and the top end is inclined outwardly. The bottom surface of the box body 1 is provided with an inwardly concave bottom groove 1a, and the bottom support plate 33 is against the box body 1 in the bottom groove 1a.

[0021] At the same time, a snap-on bent buckle 11 is provided on the side of the box body 1 and the bottom groove 1a, and a groove structure is provided on the bottom support plate 33 and the vertical frame 32 for the buckle 11 to be snapped in; the groove structure includes an entrance groove 3a and a limiting groove 3b connected end to end, the length and width of the entrance groove 3a are greater than the length and width of the buckle 11 for the buckle 11 to extend into the entrance groove 3a, the width of the limiting groove 3b is less than the width of the entrance groove 3a and the buckle 11, and is used to limit the buckle 11, so that the buckle 11 of the box body 1 is snapped into the entrance groove 3a and then moved to the limiting groove 3b to be snapped and installed with the mounting frame 3, an unlocking structure is provided at the entrance groove 3a, which is against the limiting groove 3b and is used to limit the freedom of the buckle 11 to move along the length direction of the entrance groove 3a, and the driving unlocking structure is used to release the unlocking structure that restricts the movement of the box body 1 in the separation direction on the mounting frame 3.

[0022] The unlocking structure of this embodiment is installed at the top of the stand 32. The unlocking structure includes a card plate 34 and a pull shaft 35. The card plate 34 is provided with two and the top end is movably installed at the bottom end of the pull shaft 35. Specifically, the card plate 34 can be hingedly installed on the hinge seat in the form of a hinge seat, and then the hinge seat is fixedly connected to the bottom end of the pull shaft 35. The pull shaft 35 is movably installed at the top of the stand 32. A spring 36 is provided on the pull shaft 35 under the stand 32 to provide elastic force to drive the card plate 34 to move downward. The pull shaft 35 is provided with a handle outside the top of the stand 32 to facilitate the user to pull the handle outward;

[0023] The stand 32 of this embodiment is hollow and has two vertical structural walls. The entrance grooves 3a are arranged on the structural walls on both sides. The bottom end of the card plate 34 is enlarged in thickness and cylindrical. The bottom end of the card plate 34 is embedded and engaged in the entrance groove 3a to limit the movement of the limit groove 3b. A spring 36 is provided between the two card plates 34 and the spring 36 is used to provide elastic force to drive the card plate 34 to move toward the entrance grooves 3a on both sides. The spring 36 of the pull shaft 35 also drives the card plate 34 to move downward so that the card plate 34 can better engage in the entrance groove 3a. It should be noted that the spacing between the structural walls on both sides is greater than the sum of the diameter of the cylindrical ends of the two card plates 34 and the distance the buckle head 11 extends from the entrance groove 3a. Therefore, when the box body 1 is installed, during the process of buckling the buckle head 11 from the entrance groove 3a, even if the card plate 34 is directly buckled into the entrance groove 3a, the pushed-in card plate 34 will not be against another card plate 34 to block the buckle head 11.

[0024] Therefore, when it is used, the mounting frame 3 is mounted on the tail seat of the electric vehicle, and the box body 1 is mounted on the mounting frame 3. First, the bottom groove 1a at the bottom end of the box body 1 is placed on the bottom support plate 33, and the buckle head 11 of the bottom groove 1a is inserted into the entrance groove 3a of the bottom support plate 33. Then, the side of the box body 1 is leaned against the stand 32, and the buckle head 11 on the side of the box body 1 is inserted into the entrance groove 3a of the stand 32. Then, the box body 1 is pushed, and the buckle head 11 of the box body 1 is buckled into the entrance groove 3a and then moved to the limiting groove 3b to be buckled and installed with the mounting frame 3. The original position of the entrance groove 3a is supported by the clamping plate 34, so that the box body 1 is limited in the limiting groove 3b and then installed on the mounting frame 3.

[0025] When the box 1 is needed for batch distribution, the pull shaft 35 is pulled upward, and the pull shaft 35 rises with the card plate 34. The bottom end of the card plate 34 slides from the entrance groove 3a to the inner wall of the stand 32, thereby releasing the restriction on the entrance groove 3a. Then the box 1 is pushed from the limit groove 3b to the entrance groove 3a, and the box 1 can be removed from the mounting frame 3 and carried by the shoulder strap 4 for distribution.

[0026] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
