Description

Technical Field

[0001] The invention relates to the technical field of EPS foam boxes, in particular to an EPS foam box with good thermal insulation performance. Background Art

[0002] EPS foam box is a common packaging material made of polystyrene (EPS) foam.

[0003] EPS foam boxes are suitable for packaging various types of items, especially for fragile, light or irregularly shaped items. They are widely used in industries such as electronics, glass products, ceramic products, food, medical equipment, and artworks to ensure the safety and integrity of products during transportation and storage.

[0004] When loading items into an EPS foam box, if the items are close to the inner wall of the EPS foam box, it may increase the difficulty of placing the items into the box, especially for large or irregularly shaped items. When the items are in close contact with the inner wall of the EPS foam box, it may cause difficulties in taking out the items. Especially for heavy items or boxes with good sealing, it may take a lot of effort to take the items out.

[0005] In summary, the prior art lacks a technology for facilitating the placement and removal of items in a certain EPS foam box. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the background technology and to propose an EPS foam box with good thermal insulation.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is: an EPS foam box with good thermal insulation, comprising an outer shell, an EPS foam frame is fixedly connected inside the outer shell, a box cover is movably inserted on the outer shell, and a clamping mechanism is slidably provided inside the box cover; A lifting seat is slidingly arranged in the shell, a lifting mechanism is rotatably connected to the bottom of the shell near the lifting seat, sliding racks are slidingly arranged on the inner walls on both sides of the shell, and positioning mechanisms are slidingly arranged on the inner walls on both sides of the shell.

[0008] Preferably, storage grooves are provided at the bottoms of both sides of the shell, and handle grooves are provided at the outer walls of both sides of the shell.

[0009] Preferably, an EPS foam top seat is fixedly connected to the bottom of the box cover, a handle is fixedly connected to the middle of the top of the box cover, and anti-slip grooves are provided at the four corners of the box cover.

[0010] Preferably, the locking mechanism includes two sliding rods, the sliding rods and the box cover are slidably matched, a plurality of springs are connected and fixed between the two sliding rods, a toggle rod is connected and fixed on one end of the two sliding rods, a locking arc block is connected and fixed on the other end of the sliding rod, a locking groove is provided at a position near the locking arc block on the top of the shell, and the locking groove is movably locked with the outer wall of the locking arc block.

[0011] Preferably, an EPS foam base is fixedly connected to the top of the lifting seat, and the bottom of the lifting seat is symmetrically structured with two slide grooves.

[0012] Preferably, the lifting mechanism includes a worm, which is rotatably connected to the bottom inner wall of the outer shell through the worm, a knob is fixedly provided at the outer end of the worm, a worm wheel is meshingly provided at the inner end of the worm, a rotating shaft is fixedly provided in the middle of the worm wheel, and both ends of the rotating shaft are rotatably connected to the bottom inner wall of the outer shell.

[0013] Preferably, both ends of the rotating shaft are connected and fixed with a bevel gear A, the bevel gear A is meshingly transmitted with a bevel gear B, the bevel gear B is rotatably connected to the inner wall of the bottom of the shell through a transmission rod, a lifting rod is connected and fixed on the transmission rod, and a sliding column is connected and fixed on the other end of the lifting rod, and the outer wall of the sliding column is slidably matched with the inner wall of the slide groove.

[0014] Preferably, both ends of the sliding frame are rotatably connected with moving wheels, and two tension springs are fixedly connected to the sliding frame, and the other ends of the tension springs are fixedly connected to the inner wall of the storage slot.

[0015] Preferably, the positioning mechanism includes a handle, which is slidably matched with the inner wall of the storage groove, the bottom end of the handle is rotatably connected with two connecting rods, the other end of the connecting rod is rotatably connected with an insertion rod, the inner walls on both sides of the storage groove are provided with slots, and the insertion rod is movably plugged into the inner wall of the slot.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When placing or taking out an item, the lifting seat will be lifted up by the lifting mechanism. At this time, when placing or taking out an item, it will not be restricted by the inner wall of the shell, so that placing or taking out an item is convenient and quick. By setting a positioning mechanism, the sliding rack can be easily retracted and released. Under the action of the moving wheels, when heavy items are loaded, they can be moved without lifting, thereby reducing labor and further improving the loading and unloading efficiency of items. By setting up a snap-on mechanism, the box cover and the shell can be quickly connected without the need for tape packaging, thereby ensuring the tightness of the connection between the box cover and the shell. At the same time, the anti-slip groove on the box cover can limit the moving wheels, thereby facilitating stability when multiple devices are stacked. BRIEF DESCRIPTION OF THE DRAWINGS
