[0017] The following describes the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.
[0018] Example 1
[0019] A pull-out cabinet includes: a cabinet body 1, drawers 2, a sealing cover 3, and bottom wheels 4. The bottom wheels 4 are located at the bottom of the cabinet body 1. Several sets of drawers 2 are provided and slidably disposed within the cabinet body 1. The bottom drawer 2 includes a cavity 21 inside. A rectangular baffle 22 is provided on the upper side of the cavity 21. A sealing strip 23 is provided around the upper end of the rectangular baffle 22. The sealing cover 3 is slidably disposed within the cavity 21. A second sealing strip 31 is provided around the side end of the sealing cover 3. A retaining edge 32 is provided around the bottom of the sealing cover 3. The retaining edge 32 is engaged with the inner side of the rectangular baffle 22. A handle 33 is provided at the bottom of the sealing cover 3. A placement cavity 11 for accommodating the sealing cover 3 is provided on the side end of the cabinet body 1.
[0020] like Figures 1-4 As shown, the working principle of this utility model is as follows:
[0021] The cabinet is equipped with casters at the bottom for easy movement.
[0022] The multi-layered drawers slide within the cabinet. The lowermost drawer has a rectangular baffle on the upper side of its interior cavity, with a sealing strip at its upper end forming a double seal with a sealing strip on the side of the sealing cover. The sealing cover engages with the inner side of the rectangular baffle via a snap-fit at the bottom, achieving a tight seal around the cavity. A handle facilitates the removal and placement of the cover, while a storage cavity on the side of the cabinet provides storage space for the removed sealing cover.
[0023] Specifically, when sealing items for storage is required, place the items in the cavity of the bottom drawer, and slide the sealing cover into the cavity using the handle. The vertical part of the locking edge engages with the inner side of the rectangular guard, ensuring a tight seal between the sealing cover and the cavity opening. At this point, sealing strip one contacts the upper surface of the sealing cover, and sealing strip two contacts the side of the cavity, forming a sealing barrier from the top, bottom, and sides, preventing outside air and moisture from entering the cavity. When the sealing cover is not needed, it can be removed from the cavity and stored in the storage compartment on the side of the cabinet, without taking up interior drawer space.
[0024] It effectively solves the sealing defects of traditional open drawers and is suitable for storing environmentally sensitive items.
[0025] As a further preferred embodiment, the upper end of the rectangular retaining edge 22 is provided with a groove 221, and the sealing strip 23 is disposed in the groove 221. The sealing strip 23 is fixed in a preset position by the limiting effect of the groove, ensuring that the sealing strip is tightly fitted to the upper surface of the sealing cover plate.
[0026] In a further preferred embodiment, the sealing cover plate 3 has a second groove 311 on its side, and the second sealing strip 31 is disposed within the second groove 311. The second sealing strip is arranged circumferentially along the side of the sealing cover plate. When the cover plate slides into the cavity, the second sealing strip contacts the side wall of the cavity and fills the side gap by elastic deformation. The function of the second groove is similar to that of the first groove, ensuring the positional accuracy of the second sealing strip through structural limiting and avoiding side sealing failure.
[0027] As a further preferred embodiment, the locking edge 32 includes a vertical portion 321 and a locking hook 322. The locking hook 322 is fixed to the lower end of the vertical portion 321. The upper and lower ends of the outer side of the locking hook 322 are provided with arc-shaped guide portions 323. The arc-shaped guide portions at the upper and lower ends play a guiding role during the locking process. When the sealing cover plate is inserted downward into the cavity, the arc-shaped guide portion of the locking hook first contacts the inner side of the rectangular retaining edge. Through the guiding effect of the arc-shaped surface, the locking hook smoothly slides into the inner side of the retaining edge to complete the locking. During disassembly, the arc-shaped guide portion reduces the frictional resistance between the locking hook and the retaining edge, making it easier to lift the cover plate upward.
[0028] As a further preferred embodiment, the drawers 2 are provided in three sets, with the internal depth of the three sets of drawers 2 decreasing sequentially upwards. The drawer layout with decreasing depth optimizes the utilization of cabinet space, with the shallow upper drawers suitable for storing frequently used small items, and the deep lower drawers meeting the needs of storing large items or sealed items.
[0029] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
