[0008] By adopting the above technical solution, when the insulation box of the present application is used, the food or dishes containing food are directly placed on the boss, and then the user grasps the two handles and inserts the cover into the ring groove to complete the work of placing and keeping the food warm. When taking the food, just grasp the two pull blocks and directly lift the cover from the storage tray, and then you can directly take the food or dishes on the storage tray. Compared with the traditional box-type storage structure, the insulation box structure of this product eliminates the cavity structure, so that when the user takes the food or dishes, there is no object to hinder the movement of the fingers and wrists, making it more convenient for the user to take the food or dishes. At the same time, the setting of the boss allows the user's fingers to easily reach the bottom of the dishes or food, so that the user can easily grasp the food or dishes, making it more convenient for the user to apply force.

[0009] Preferably, the first connecting portion includes a first plug rod provided on the handle and a first plug hole provided on the heat-insulating cover, and the first plug rod is plug-fitted with the first plug hole.

[0010] By adopting the above technical solution, the connection between the cover body and the pull block can be completed by inserting the first insertion rod into the first insertion hole, and the connection method is simple.

[0011] Preferably, the heat preservation cover includes a cover body and a cover plate arranged on the cover body, the top of the cover body is provided with a accommodating cavity, the inner wall of the accommodating cavity is provided with a first anti-slip portion, the bottom of the cover plate is provided with an annular mounting block, the annular mounting block extends into the accommodating cavity, the annular mounting block is provided with a second anti-slip portion, the first anti-slip portion and the second anti-slip portion abut against each other to limit the separation of the cover body and the cover plate.

[0012] By adopting the above technical solution, the cover body and the storage tray of the present application are both plastic parts, and both need to be produced by injection molding using a mold. If the thermal insulation cover body is directly injection molded using only one mold, the volume of the mold used to injection mold the thermal insulation cover body will be relatively large, and the design difficulty will also be higher, so the manufacturing cost of the mold will be relatively high. Therefore, in order to reduce production costs, the thermal insulation cover body is divided into a cover body body and a cover plate to manufacture molds separately for production. After the cover body body and the cover plate are produced, the annular mounting block is inserted into the accommodating cavity, and then the first anti-slip portion and the second anti-slip portion are used to limit the separation of the cover body body and the cover plate body, thereby completing a production combination of a cover body body.

[0014] By adopting the above technical solution, when the cover body and the cover plate are combined, the annular mounting block is inserted into the mounting cavity, and then the cover plate is rotated so that the limit block collides with the first limit bar. At this time, the first limit bar will abut against the second limit bar and the first limit bar is located on the side of the second limit bar away from the bottom wall of the accommodating cavity, thereby limiting the separation of the cover body and the cover plate and completing the assembly of an insulation cover.

[0015] Preferably, the top of the cover plate is recessed to form an installation cavity, a lifting block is installed in the installation cavity, the bottom of the bottom wall of the installation cavity is recessed to form a second socket, a second plug rod is provided at the bottom of the lifting block, and the second plug rod is plugged into the second socket.

[0016] By adopting the above technical solution, the lifting block is provided to facilitate the rotation and lifting of the cover plate, thereby facilitating the assembly of the cover plate and the cover body. At the same time, the lifting block also plays a decorative role.

[0017] Preferably, a threaded hole is provided on the surface of the second insertion rod away from the lifting block, and an avoidance hole penetrating the cover plate is provided on the bottom wall of the second insertion hole. A bolt is also provided on the cover plate, and the screw rod of the bolt passes through the avoidance hole and is threadedly connected in the threaded hole, and the head of the bolt contacts the inner wall of the cover plate.

[0019] Preferably, the number of the second plug holes is at least two, and the number of the second plug rods is at least two.

[0020] By adopting the above technical solution, when the cover plate is rotated by rotating the lifting block, the single second insertion rod is easy to rotate by itself in the second insertion hole and cannot drive the cover plate to rotate. Therefore, at least two second insertion rods need to be provided to ensure that the lifting block rotates with the cover plate, while improving the firmness of the connection between the lifting block and the cover plate.

[0021] Preferably, a heat preservation plate is provided inside the cover body, and a storage cavity for storing food is formed between the heat preservation plate, the cover body and the storage tray, a positioning block is provided on the heat preservation plate, and a third plug rod is provided on the positioning block, and a plurality of third plug holes for plugging with the third plug rod are opened on the inner wall of the cover body, and the plurality of second plug holes are arranged equidistantly along the height direction of the cover body.

[0022] By adopting the above technical solution, the smaller the storage cavity is, the better the heat preservation effect is when the food storage conditions are met. Therefore, before storing food each time, the third insertion rod is inserted into the third insertion hole of different heights according to the height of the food to adjust the size of the storage cavity, so that the heat preservation box has excellent heat preservation effect on the food.

[0023] Preferably, the insulation board is provided with a slide groove, and the positioning blocks are respectively slidably connected in the slide groove.

[0024] By adopting the above technical solution, when adjusting the insertion position of the third plug rod, the sliding positioning block can pull the third plug rod out of the original third plug hole, and then hold the positioning block to adjust the height of the positioning block so that the third plug rod is aligned with the new third plug rod, and then the sliding positioning block can insert the third plug rod into the third plug hole to complete the adjustment of the position of the insulation board. If there is no sliding structure, the adjustment of the third plug rod to insert into different third plug holes is all done by bending the cover body to deform the cover body so that the third plug rod can be pulled out of the third plug hole. If the cover body is bent too much, the deformation will be unable to recover, and it cannot be inserted well in the ring groove, so that the cover body and the storage tray cannot be effectively sealed, which reduces the insulation performance of the insulation box.

[0025] The technical effects of this utility model are mainly reflected in the following aspects:

[0026] 1. The utility model makes it more convenient to take food or dishes by combining the storage tray and the heat preservation cover.

[0027] 2. The utility model completes the connection between the cover plate and the cover body through the cooperation of the first limit strip, the second limit strip and the limit block;
