As a result, the fast food box is easily shaken when carried in the insulation bag, causing food to spill. For this reason, we propose a multifunctional insulation bag. Utility Model Content

[0004] The utility model aims to provide a multifunctional insulation bag to solve the problem that the insulation bag proposed in the above background technology is prone to shaking and causes food to spill out.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional insulation bag, comprising an insulation bag body, a screw is fixed inside the insulation bag body, a rotary cylinder is threadedly connected to the screw, a baffle plate is arranged on the inner side of the insulation bag body, and the rotary cylinder is embedded in the baffle plate by rotation.

[0006] Preferably, a guide hole is opened on the surface of the baffle plate, a guide rod passes through the inside of the guide hole, and the guide rod is fixed on the inner wall of the heat-insulating bag body.

[0007] Preferably, the outer walls at both ends of the rotary cylinder are sleeved with anti-slip sleeves.

[0008] Preferably, the cross section of the rotary drum is an I-shaped structure, and the longitudinal section of the rotary drum is a circular structure.

[0011] Preferably, the longitudinal section of the baffle plate is an L-shaped structure, and sponge pads are fixed to both side surfaces of the baffle plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) Through the designed screw, rotary drum and baffle, the baffle is installed in the insulation bag body through the screw and rotary drum with adjustable position. After the fast food box is placed in the insulation bag body, the rotary drum is rotated, the rotary drum and the screw are screwed, and the baffle is squeezed on the side of the fast food box. The threaded connection between the rotary drum and the screw has a self-locking characteristic, which fixes the position of the baffle and realizes the fixation of the position of the fast food box in the insulation bag body to prevent the fast food box from shaking in the bag during movement and causing food to spill. Through the designed guide rod and guide hole, the baffle is adjusted and guided to avoid deviation. Through the designed anti-slip sleeve, the friction resistance of the rotary drum surface is increased to avoid hand slippage when the rotary drum is rotated. Through the designed ball bearing, it plays a lubricating role and reduces the wear on the surface of the rotary drum and the baffle. Through the designed rib plate, the screw installation is reinforced. Through the designed sponge pad, it is prevented that the baffle and the fast food box are directly in contact with each other, which may cause damage to the fast food box.
