Description

Technical Field

[0001] This utility model relates to an insulated box, and more particularly to an insulated box with adjustable height and retraction. Background Technology

[0002] An insulated box is a device that uses a heating / cooling module to achieve refrigeration or insulation. It is commonly used in the food, medical, and pharmaceutical industries to ensure that the temperature of goods remains stable during transportation. Currently, for ease of use, existing insulated boxes often include adjustable functions to meet the needs of users at different heights.

[0003] Existing adjustable insulated boxes basically consist of a support base, an adjusting component, and the insulated box body. The adjustment method involves using the adjusting component to change the distance between the support base and the insulated box body. However, because the adjusting component is too closely related to the support base and the insulated box body, the support base and the insulated box body are moved when the adjusting component is adjusted. Therefore, it is necessary to restrict the support base and the insulated box body during use. For example, the adjustable lifting-leg refrigerator with authorization announcement number CN222012436U requires restrictions on the placement plate and the box body when adjusting the height using the control slider. Therefore, in summary, existing insulated boxes have the problem of inconvenient operation during adjustment. Utility Model Content

Detailed Implementation

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes the structure of the insulated box, as follows:

[0024] A retractable insulated box, combined with Figures 1-3As shown, it includes: a base 1, a box body 2, fixed posts 3, mounting plates 5, movable plates 6, guide rods 7, a return spring 8, a first rack 9, a gear 10, a mounting block 11, and a second rack 12; the box body 2 is placed on the base 1, and the friction between the base 1 and the box body 2 is less than the weight of the base 1; fixed posts 3 are fixedly installed at the four corners of the base 1; the fixed posts 3 have slots 4, and slots 4 at the same height on each fixed post 3 constitute one layer, with a total of twelve layers of slots 4. The more layers of slots 4, the higher the adjustment accuracy of the insulation box; mounting plates 5 are fixedly installed on both sides of the box body 2; guide rods 7 are fixedly installed on the mounting plates 5; movable plates 6 are slidably installed on the guide rods 7; guide rods 7 8, and movable plates 9 8. A return spring 8 is fitted on the rod 7, and the two ends of the return spring 8 are fixed to the moving plate 6 and the mounting plate 5 respectively. The front and rear ends of the moving plate 6 are each equipped with a first rack 9. The front and rear ends of the mounting plate 5 are each rotatably equipped with a gear 10, and the first rack 9 at each of the four corners meshes with the gear 10. The front and rear ends of the mounting plate 5 are each fixedly equipped with a mounting block 11. The mounting block 11 is slidably equipped with a second rack 12, and the second rack 12 at each of the four corners meshes with the gear 10. The height positions of the first rack 9 and the second rack 12 at each location are misaligned, and the movement of each second rack 12 can be inserted into the corresponding slot 4 on each fixed post 3 to stabilize the position between the housing 2 and the base 1.

[0025] When adjusting the height of the insulated box, the user holds the movable plate 6 and the mounting plate 5 on both sides of the box body 2 respectively, presses the movable plate 6, and controls the movable plate 6 to slide towards the mounting plate 5. The return spring 8 is compressed, and the first rack 9 drives the gear 10 to move the second rack 12. The second rack 12 is pulled out from the slot 4, unlocking the fixation between the box body 2 and the fixed post 3. Then, the box body 2 can be easily moved up and down to change its height. After determining the height position of the box body 2, the movable plate 6 is released, and the return spring 8 resets the movable plate 6 to move away from the mounting plate 5. The second rack 12 is then controlled to insert into the slot 4 at the corresponding height, thereby fixing the box body 2 and the fixed post 3. At this time, the box body 2 can be used at this height position.
