[0002] Drawer chests are an important part of home and tool storage. In humid environments such as outdoors, kitchens, and bathrooms, the need for waterproofing in drawer chests is particularly significant. The waterproof design of drawer chests needs to balance waterproof performance with practicality, taking into account both the chest's sealing and drainage capabilities, as well as the smooth opening and closing of the drawers and ease of use.

[0003] In existing technology, a sealing strip is typically installed at the opening of the drawer box to prevent external moisture from entering the interior of the drawer box. However, every time the drawer is opened and closed, it comes into contact with and rubs against the sealing strip, which accelerates the aging of the sealing strip, affects its waterproof effect, and also increases the resistance when opening and closing the drawer, making it inconvenient to use. Utility Model Content

[0004] In view of this, this application provides a waterproof component for a drawer box, which has a good waterproof effect, a stable and reliable structure, and convenient drawer use.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0047] like Figures 1-11 As shown, this application embodiment provides a waterproof component for a drawer box, applied to a drawer box. The drawer box includes a drawer box body 1 and at least one drawer 2 disposed within the drawer box body 1, that is, one or more drawers 2 are disposed within the drawer box body 1. The drawer 2 has a closed state and a pulled-out state, wherein the closed state of the drawer 2 refers to the state in which the drawer 2 is not pulled out from the box opening 101 of the drawer box body 1 and is located inside the drawer box body 1 (e.g., Figure 1(As shown); the pulled-out state of drawer 2 refers to the state in which drawer 2 is pulled out from the box opening 101 of the drawer box body 1.

[0048] Drawer 2 has a back panel 202, a front panel 203, a bottom panel 204, and two side panels 205. The two side panels 205 are connected between the back panel 202 and the front panel 203 to form a square area, which is located above the bottom panel 204. The left-right direction of drawer 2 is the arrangement direction of the two side panels 205. Figure 3 , 4 As shown in the X direction, the vertical direction of drawer 2 corresponds to the arrangement of the square area and the base plate 204. Figure 3 , 4 As shown in the Z direction, the direction in which drawer 2 is pulled out is from the back panel 202 to the front panel 203 of drawer 2, that is... Figure 2 , 3 Y direction shown.

[0049] The waterproof component includes a sealing cap 3 and a sealing ring 4. The sealing cap 3 covers the opening 201 of the drawer 2, and the drawer 2's internal space is sealed by the sealing cap 3 closing onto its opening 201. That is, when the sealing cap 3 closes onto the opening 201 of the drawer 2 to seal the internal space of the drawer 2, the drawer 2 is in a sealed state (e.g., Figure 3 (As shown); when the sealing cover 3 moves relative to the drawer 2, opening the internal space of the drawer 2, the drawer 2 is in the open state (as shown). Figure 4 (As shown). A sealing ring 4 is disposed on at least one of the sealing cover 3 and the drawer 2, so that the sealing ring 4 can be pressed between the sealing cover 3 and the drawer 2 to complete the sealing of the drawer 2. In this embodiment, the sealing ring 4 is disposed on the side of the sealing cover 3 near the opening 201 of the drawer 2, and is arranged in a ring around the entire opening 201 of the drawer 2, providing good sealing performance. In other embodiments, the sealing ring 4 may also be disposed at the opening 201 of the drawer 2, and the sealing ring 4 may also be discontinuous in shape. Preferably, the size and shape of the sealing ring 4 match the size and shape of the end face of the opening 201 of the drawer 2.

[0050] During use, the user applies pressure to press the sealing cover 3, the sealing ring 4, and the drawer 2 together, thus sealing the drawer 2. This is achieved by pressing the sealing cover 3 and the drawer 2 together to seal the sealing ring 4. This design, by pressing the sealing cover 3, the sealing ring 4, and the drawer 2 together, ensures that the drawer 2 is sealed, its internal space is enclosed, and the sealing structure is stable and reliable. This prevents external moisture or impurities from entering the drawer 2, achieving a high level of waterproofing. Furthermore, installing waterproof components on individual drawers 2 ensures both high reliability of the waterproof components and ease of use when opening and closing each drawer 2.

[0051] Specifically, in this embodiment, the sealing cover 3 has an annular groove 301 on its side near the drawer 2, and the sealing ring 4 is disposed within the annular groove 301. The annular groove 301 can limit and fix the sealing ring 4, thereby keeping the sealing ring 4 in a preset posture and preventing deformation or displacement of the sealing ring 4 under force. An annular protrusion 206 is provided at the opening 201 of the drawer 2. When the drawer 2 is in a sealed state, the annular protrusion 206 abuts against the sealing ring 4 in the annular groove 301, thereby pressing the sealing ring 4 in the annular groove 301 tightly under the same pressure. This reduces the contact area and improves the sealing performance of the drawer 2. The width of the annular protrusion 206 is smaller than the width of the groove opening of the annular groove 301, which increases the pressure between the annular protrusion 206 and the sealing ring 4, causing the sealing ring 4 to deform more under force and providing a better sealing and waterproof effect.

[0052] In this embodiment, the waterproof component also includes a locking structure 5. The user applies pressure to the sealing cover 3, the sealing ring 4, and the drawer 2 through the locking structure 5, thereby achieving a sealed state for the drawer 2. This embodiment lists three different locking structures 5, which will be described in detail below.

[0053] [First Embodiment]

[0054] like Figure 4-6As shown, in the first embodiment, the locking structure 5 includes a protrusion 501 and a mating part 502. The protrusion 501 is located on the side of the sealing cover 3 away from the drawer 2, and the mating part 502 is located on the side of the drawer body 1 near the drawer 2. The positions of the protrusion 501 and the mating part 502 correspond to each other. When the drawer 2 moves from the pulled-out state to the closed state, the protrusion 501 and the mating part 502 press against each other to achieve a sealed state for the drawer 2. In this way, during the closing process of the drawer 2, no additional pressure is required from the user. The locking structure 5 relies on the pushing force of closing the drawer 2. When the protrusion 501 on the sealing cover 3 moves to contact the mating part 502 on the drawer body 1, in order to continue closing the drawer 2, the protrusion 501 needs to press against the mating part 502 to achieve a sealed state for the drawer 2.

[0055] Specifically, during the closing process of drawer 2, such as Figure 5 As shown, the protrusion 501 can directly pass over the mating part 502, achieving instantaneous pressure to seal the drawer 2. After passing over the mating part 502, the protrusion 501 presses the sealing cover 3, the sealing ring 4, and the drawer 2 tightly together. That is, when the drawer 2 is in a sealed state, the protrusion 501 and the mating part 502 do not abut against each other. Here, through the instantaneous contact and compression between the protrusion 501 and the mating part 502, the sealing cover 3, the sealing ring 4, and the drawer 2 are pressed together tightly. Even after the protrusion 501 passes over the mating part 502, the sealing cover 3, the sealing ring 4, and the drawer 2 remain tightly pressed together. A first inclined surface 503 is provided on one side of the protrusion 501 and / or the mating part 502, and a second inclined surface 504 is provided on the other side of the protrusion 501 and / or the mating part 502. When the drawer 2 switches between the pulled-out state and the closed state, the protrusion 501 and the mating part 502 cooperate through the first inclined surface 503, allowing the protrusion 501 to pass over the mating part 502 during the closing process. Similarly, the protrusion 501 and the mating part 502 cooperate through the second inclined surface 504, allowing the protrusion 501 to pass over the mating part 502 during the pulling-out process. Thus, the protrusion 501 can be positioned arbitrarily on the sealing cover 3, offering flexibility in its placement and ease of manufacturing.

[0056] The waterproof component also includes a hinge structure 6. The sealing cover 3 is connected to the opening 201 of the drawer 2 via the hinge structure 6, allowing the sealing cover 3 to be flipped relative to the drawer 2. This flipping of the sealing cover 3 allows it to switch between a sealed and open state. In this way, the sealing cover 3 is rotatably connected to the opening 201 of the drawer 2, facilitating switching between sealed and open states. The operation is simple, the connection is stable and reliable, and it also prevents the sealing cover 3 from being lost after complete disassembly.

[0057] like Figure 4As shown, in this embodiment, the hinge structure 6 includes a first hinge tube 601, a second hinge tube 602, a third hinge tube 603, and a hinge shaft 604. The first hinge tube 601, the second hinge tube 602, and the third hinge tube 603 are coaxially arranged. The second hinge tube 602 is located between the first hinge tube 601 and the third hinge tube 603 and is mounted on the sealing cover 3. The first hinge tube 601 and the third hinge tube 603 are mounted on the drawer 2. The hinge shaft 604 passes through the first hinge tube 601, the second hinge tube 602, and the third hinge tube 603, allowing the sealing cover 3 to rotate around the hinge shaft 604. Furthermore, to ensure the hinge structure 6 has waterproof properties, its location differs from traditional structures. Specifically, when drawer 2 is in a sealed state, the hinge structure 6 is located on the side of the sealing ring 4 away from the opening 201 of drawer 2, and the protrusion 501 and the mating part 502 are always in contact on the other side of the opening of drawer 2.

[0058] Furthermore, the hinge structure 6 and the locking structure 5 are respectively disposed on opposite sides of the sealing cover 3. Thus, when the drawer 2 is closed, the hinge structure 6 and the locking structure 5 seal and lock on opposite sides of the sealing cover 3, which helps improve the force balance of the sealing cover 3 and enhances the stability and sealing performance of the sealing cover 3 in closing the drawer 2. It should be noted that the hinge structure 6 and the locking structure 5 are disposed opposite to each other on the two side panels 205, or on the back panel 202 and the front panel 203, respectively. In this embodiment, since the sealing ring 4 needs to surround the outer periphery of the opening 201 of the drawer 2, the hinge structure 6 needs to be located on the side of the sealing ring 4 away from the opening 201 of the drawer 2, and the locking structure 5 needs to be located on the other side of the sealing ring 4 away from the opening 201 of the drawer 2. That is, the hinge structure 6 and the locking structure 5 are disposed opposite to each other on the outside of the sealing ring 4.

[0059] like Figure 3As shown, the sealing cover 3 has a first side 302 and a second side 303. When the sealing cover 3 is in a sealed state, the first side 302 of the sealing cover 3 is close to the back panel 202 of the drawer 2, and the second side 303 of the sealing cover 3 is close to the front panel 203 of the drawer 2. A hinge structure 6 is provided on the first side 302 of the sealing cover 3, and a locking structure 5 is provided on the second side 303 of the sealing cover 3. Thus, during the closing process of the drawer 2, the back panel 202 and the sealing cover 3 are always connected, preventing the sealing cover 3 from accidentally separating from the drawer 2 and obstructing its closing, thus facilitating the closing of the drawer 2. During the opening process of the drawer 2, the drawer 2 does not need to be fully opened to unlock the locking structure 5 near the front panel 203, allowing the drawer opening 201 to open and facilitating the access of smaller parts inside the drawer 2. Furthermore, to facilitate the opening of the sealing cover 3, a handle portion 304 is provided on the second side 303 of the sealing cover 3. The handle portion 304 protrudes from the sealing cover 3 along the Y direction, allowing the user to apply force to the sealing cover 3.

[0060] [Second Embodiment]

[0061] In the second embodiment, in order to achieve better sealing performance of drawer 2, such as Figure 6 As shown, the protrusion 501 of the locking structure 5 in the closed state always presses against its corresponding mating part 502, that is, the mating part 502 is positioned aligned with the protrusion 501. A first inclined surface 503 is provided on one side of the protrusion 501 and / or the mating part 502, so that as the protrusion 501 approaches the mating part 502, the first inclined surface 503 continuously compresses the sealing ring 4 until the protrusion 501 and the mating part 502 are in a vertical abutment. Compared to the structure where the user directly applies pressure to press the sealing cover 3, the sealing ring 4, and the drawer 2 tightly together, this structure is simpler, easier to operate, and achieves the seal of the drawer 2 without additional pressure.

[0062] In this embodiment, as Figure 1 , 2As shown in Figures 3, 4, and 6, the locking structure 5 includes a protrusion 501 and a mating part 502. The protrusion 501 is located on the side of the sealing cover 3 away from the drawer 2, and the mating part 502 is located on the side of the drawer body 1 near the drawer 2 (in this embodiment, the mating part 502 can be a part of the drawer body 1). When the drawer 2 is in the closed state, the drawer 2 is inside the drawer body 1, and the protrusion 501 abuts against the mating part 502 on the drawer body 1. The mating part 502 on the drawer body 1 presses against the protrusion 501 on the sealing cover 3, so that the sealing cover 3 presses the sealing ring 4 against the opening 201 of the drawer 2, thereby keeping the drawer 2 in a sealed state. As long as the drawer 2 is in the closed state, the protrusion 501 and the mating part 502 remain in abutment, and the drawer 2 remains sealed, thereby improving the waterproof performance of the drawer 2.

[0063] In this embodiment, drawer 2 is also provided with a hinge structure 6; wherein, the hinge structure 6 is provided on the first side 302 of the sealing cover 3 near the back panel 202, and the protrusion 501 is provided on the second side 303 of the sealing cover 3 near the front panel 203. For example, when the sealing cover 3 is in a sealed state, the protrusion 501 is located above the front panel 203. A first inclined surface 503 is provided on the first side 302 of the protrusion 501 near the sealing cover 3 so that the height of the protrusion 501 gradually decreases in the direction near the first side 302 of the sealing cover 3. During the closing process of drawer 2, the drawer body 1 first abuts against the first inclined surface 503 on the protrusion 501. Under the action of the first inclined surface 503, the drawer body 1 slides along and over the first inclined surface 503 until the mating part 502 on the drawer body 1 abuts against the protrusion 501. In this way, the first inclined surface 503 on the protrusion 501 can gradually press the sealing cover 3, thereby improving the sealing degree of the sealing cover 3 on the drawer 2. Alternatively, the first inclined surface 503 can be set on one side of the mating part 502. The first inclined surface 503 on the mating part 502 can also gradually press the sealing cover 3. In addition, the protrusion 501 can also be set on the side of the sealing cover 3 near the side panel of the drawer 2. For example, there are two protrusions 501, and the two protrusions 501 are respectively close to the two side panels of the drawer 2 (this structure is not shown in the figure).

[0064] like Figure 3As shown, both the protrusion 501 and the mating part 502 are strip-shaped. The extending direction of the protrusion 501 and the extending direction of the mating part 502 are parallel and perpendicular to the line connecting the first side 302 to the second side 303 of the sealing cover 3. That is, the extending direction of the protrusion 501 is perpendicular to the pull-out direction and the closing direction of the drawer 2, and the extending direction of the protrusion 501 is parallel to the hinge axis 604 of the hinge structure 6. In this way, a sealing strip can be formed above the front panel 203 of the drawer 2 by the protrusion 501, further preventing external moisture and impurities from entering the drawer body 1. Moreover, the protrusion 501 can fully contact the drawer body 1, improving the effect and balance of the drawer body 1 in pressing the sealing cover 3.

[0065] [Third Embodiment]

[0066] like Figure 7-11 As shown, in the third embodiment, the locking structure 5 includes a locking element 505 and a locking groove 506. One of the locking element 505 and the locking groove 506 is disposed on the sealing cover 3, and the other is disposed on the drawer 2. For example, the locking element 505 is disposed on the first side 302 of the sealing cover 3, and the locking groove 506 is disposed on the front panel 203 of the drawer 2. The locking element 505 can be driven to move when the sealing cover 3 is opened and closed. The locking structure 5 has a locked state and an unlocked state. When the locking structure 5 is in the locked state, the locking element 505 and the locking groove 506 interfere with each other in the opening direction of the sealing cover 3, thereby restricting the movement of the sealing cover 3 relative to the drawer 2 in the opening direction. When the locking structure 5 is in the unlocked state, the locking element 505 and the locking groove 506 do not interfere with each other in the opening direction of the sealing cover 3, thereby removing the restriction on the sealing cover 3, so that the sealing cover 3 can move relative to the drawer 2 in the opening direction.

[0067] The locking groove 506 is located on the drawer 2, and the locking element 505 can be flipped and connected to the sealing cover 3 via another hinge structure. That is, the locking structure 5 is a flip-lock. When the sealing cover 3 is in the sealed state, the locking element 505 interferes with the locking groove 506. When the sealing cover 3 needs to be opened, the user applies force to flip the locking element 505 relative to the sealing cover 3, thus switching the locking structure 5 from the locked state to the unlocked state. In this way, the state switching of the locking structure can be achieved simply by moving the locking element 505, which is convenient and saves time and effort. Alternatively, to reduce connecting parts, the locking element 505 can be fixed to the sealing cover 3, and the sealing cover 3 can drive the locking element 505 to move relative to the locking groove 506 to achieve the state switching of the locking structure 5. The unlocking of the locking structure 5 and the opening of the sealing cover 3 can be achieved in a single operation. It should be noted that the locking structure 5 in the waterproof drawer box used in this embodiment is different from the general locking structure 5. This locking structure 5 has a certain pre-tightening function when locking, thereby realizing the compression between the drawer 2, the sealing cover 3 and the sealing ring 4, and achieving the sealing effect of the drawer 2.

[0068] like Figure 11 As shown, the locking element 505 includes an operating part 5051 and a locking tongue 5052. The operating part 5051 is used for the user to apply force and has a first end and a second end. The first end of the operating part 5051 is flip-connected to the sealing cover 3. The locking tongue 5052 is protruding and located in the middle of the operating part 5051 near the locking groove 506. An operating groove 207 is provided on the outer side of the front panel 203 of the drawer 2. The locking groove 506 is a component of the operating groove 207 and is the part of the operating groove 207 near the sealing cover 3. When the locking structure 5 is in the locked state, the locking tongue 5052 is located in the locking groove 506 and interferes with the part of the locking groove 506 near the sealing cover 3 in the opening direction of the sealing cover 3, so that the sealing cover 3 and the drawer 2 remain locked. Furthermore, when the locking structure 5 is in the locked state, the operating part 5051 covers a portion of the operating groove 207, that is, the end of the operating part 5051 away from the sealing cover 3 is located in the middle of the operating groove 207, and a portion of the opening of the operating groove 207 is exposed on the front panel 203. The user's fingers can be inserted into the operating groove 207 through the exposed part of the opening and pry the end of the operating part 5051 away from the sealing cover 3, so that the operating part 5051 drives the locking tongue 5052 to flip relative to the sealing cover 3 and the drawer 2, so that the locking tongue 5052 disengages from the locking groove 506, thereby unlocking the locking structure 5 and opening the sealing cover 3.
