Description

Technical Field

[0001] This utility model belongs to the field of storage products technology, and specifically refers to a storage sealing device. Background Technology

[0002] Existing storage devices such as rice containers typically include a storage body and a cover that is detachable or rotatable on the storage body. The cover is usually located on top of the storage body, especially in storage devices placed in kitchen cabinets for storing granular foods such as rice and soybeans.

[0003] For example, a rice storage bucket disclosed in the prior art CN108143322A has a sliding rice dispensing bucket at the bottom, allowing rice to be dispensed by moving the dispensing bucket. However, since the storage inlet is located at the top and is covered by a lid, the lid still needs to be removed before rice can be placed in, which is inconvenient. Some on the market also have a rotatable lid, but when the lid is located at the top, rotating and folding it increases the vertical height. If the storage space of the rice bucket is low, the lid cannot be opened, and the rice bucket is required to open the lid, which limits the usage environment.

[0004] Therefore, the applicant has designed a side-opening storage device, which includes an outer shell and a main body rotatably mounted on the outer shell. Since the main body is mounted inside the outer shell through an embedded rotating structure, a certain clearance space needs to be reserved below the embedded position of the outer shell to prevent the main body part below the rotating shaft from interfering when rotating. This makes it impossible for the main body part below the rotating shaft to fit tightly with the outer shell, and it is also impossible to set a sealing ring at this location, resulting in insufficient sealing of the storage device. Summary of the Invention

[0005] The purpose of this invention is to solve the above problems by providing a storage sealing device with a side-opening, flip-type structure that facilitates users in placing and removing items and provides a good sealing effect.

[0011] Preferably, the storage sealing device proposed in this utility model may also have the following features: a partial sealing groove is formed at the upper end of the sealing edge at the bottom; the rotating mechanism includes: a rotating seat, which is disposed on the sealing edge at the bottom below the partial sealing groove; a rotating shaft, which is disposed at the bottom of the inner front plate or the front side of the inner bottom plate and is rotatably disposed in the rotating hole; wherein, a rotation avoidance space for avoiding the bottom of the inner front plate is formed below the rotating seat.

[0012] Preferably, the storage sealing device proposed in this utility model may also have the following features: the left and right sides of the sealing edge at the bottom protrude outward to form a rotating seat; the two ends of the bottom of the inner front plate extend downward to form two rotating legs corresponding to the two rotating seats, and one side of each rotating leg protrudes to form a rotating shaft.

[0013] Preferably, the storage sealing device proposed in this utility model may also have the following features: at least one rotating support seat is provided on the sealing edge at the bottom, and a support surface is formed on the rotating support seat; at least one rotating support block is provided at the bottom of the inner front plate, the bottom of the rotating support block is semi-circular, and it rotates and cooperates with the support surface.

[0014] Preferably, the storage sealing device proposed in this utility model may also have the following features: the main body is provided with a force-applying part, which is an embedded handle or a protruding handle, and its inner side forms an insertion space and a front stop, which is used to prevent items in the storage space from falling from the front.

[0015] Preferably, the storage sealing device proposed in this utility model may also have the following feature: a blocking part is provided on the side of the storage inlet away from the front cover plate, and when the main body is rotated, the blocking part is used to prevent the items in the storage space from falling from the rear.

[0016] Preferably, the storage sealing device proposed in this utility model may also have the following feature: a buffer is provided between the outer shell and the main body, which acts on the main body to provide a buffering force when the main body rotates.

[0017] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0018] 1. The storage sealing device provided by this utility model adopts a side-opening and flipping method to open the main body, making it more convenient to place the entire storage device in the cabinet. When in use, the main body can be rotated out by simply opening the side, and items can be put in or taken out from the exposed storage entrance. It is suitable for compact cabinets and does not require moving the entire storage device, which is very convenient.

[0019] 2. The main body and shell of this utility model adopt an embedded hidden rotating structure (the front cover plate covers the outside of the rotating seat and the rotating shaft and is embedded in the shell), and a sealing element is provided between the shell and the main body or between the shell and the front cover plate, which solves the problem of sealing difficulties in embedded hidden rotating structures and improves the aesthetics of the product.

[0020] 3. After the main body of this utility model is closed, since its own gravity direction is consistent with the rotation and closing direction of the main body, it can further improve the sealing between the main body and the shell; in other words, the greater the storage weight of the main body, the better the sealing effect, thereby reducing the risk of food and other items getting damp.

[0021] 4. At least one rotating support seat is provided on the bottom sealing edge, and a support surface is formed on the rotating support seat; at least one rotating support block is provided at the bottom of the inner front plate.

[0022] 5. This utility model has a buffer between the outer shell and the main body. When the main body is opened or closed, the buffer provides a buffering force. On the one hand, it can offset part of the gravity, making it easier to open and close the main body. On the other hand, it can prevent the main body from hitting the outer shell when rotating due to excessive gravity or external force, thus improving the user experience. Attached Figure Description

[0043] <Example 1>

[0044] This embodiment proposes a storage sealing device, particularly a storage device for storing granular objects such as rice and soybeans. Figures 1-3 As shown, the storage device includes a housing 1 and a main body 2. The main body 2 is rotatably disposed within the housing 1, and the interior of the main body 2 has a storage space 21 for storing items and a placement inlet 22 for inserting items. The main body 2 also has a closed state and an open state. When in the closed state, as shown... Figure 2 As shown, the storage inlet 22 is enclosed inside the outer casing 1, meaning the entire main body 2 is located inside the outer casing 1; when in the open state, as... Figure 3 As shown, at least part of the storage inlet 22 is exposed outside the outer casing 1, allowing the user to place items into or remove items from the storage space 21. A rotating mechanism is provided between the main body 2 and the outer casing 1, enabling the main body 2 to rotate relative to the outer casing under the drive of the rotating mechanism, thereby switching the main body 2 between a closed state and an open state. In addition, a buffer 3 is provided between the outer casing 1 and the main body 2. The buffer 3 acts on the main body 2 to provide a buffering force when the main body rotates, preventing the main body 2 from instantly falling back to its original position due to its gravity, which would produce a strong impact sound or even cause the storage device to shake.

[0045] In this embodiment, the storage inlet 22 is located at the top of the accommodating space 21, meaning the main body 2 has a barrel-shaped structure with an open top, and its bottom is rotatably mounted on the outer shell 1 via a rotating mechanism, i.e., the rotating mechanism is located at the bottom of the main body 2. Specifically, as... Figures 3-5As shown, the outer casing 1 includes a shell, a front cover plate 15, and a rear cover 16. The shell is integrally formed by an outer top plate 11, an outer bottom plate 12, and two outer side plates 13 located on the left and right sides. A receiving cavity 14 for accommodating the main body 2 is formed between the outer top plate 11, the outer bottom plate 12, and the two outer side plates 13. The receiving cavity 14 has a front opening 141 and a rear opening 142 on its front and rear sides, respectively. The front cover plate 15 is openable and closable at the front opening 141, and the rear cover 16 is located at the rear opening 142. Figures 6-8 As shown, the main body 2 is barrel-shaped and has an inner front plate 23, an inner rear plate 24, an inner bottom plate 25 and two inner side plates 26. The inner front plate 23, the inner rear plate 24, the inner bottom plate 25 and the two inner side plates 26 form a receiving space 21 with a storage entrance 22 at the top. The inner front plate 23 is fixed to the front cover plate 15.

[0046] A rotating seat 17 is provided on the bottom front side of the housing (i.e., the front side of the outer bottom plate 12 located at the front opening 141). A rotating hole 171 is provided within the rotating seat 17. A rotating shaft 27, rotatably mounted on the rotating hole 171, is provided on the bottom of the inner front plate 23 or the front side of the inner bottom plate 25. The mutual rotation between the main body 2 and the housing is achieved through the cooperation of the rotating shaft 27 and the rotating hole 171. In this embodiment, as... Figure 5 As shown, the front side of the outer base plate 12 extends upward at the front opening 141 to form a mounting plate 121. The left and right sides of the mounting plate 121 protrude outward near their ends to form rotating seats 17 (left rotating seat and right rotating seat). The left and right rotating seats have rotating holes 171 facing the left and right sides respectively. Figure 6 As shown, the bottom ends of the inner front plate 23 extend downward to form two rotating feet 231 (left rotating foot and right rotating foot) corresponding to the two rotating seats. The left rotating foot and right rotating foot protrude to the right and left sides (i.e., the direction corresponding to the rotating hole 171) respectively to form a rotating shaft 27, as shown. Figure 9 As shown, the two rotating shafts 27 are respectively inserted into the corresponding rotating holes 171. In order to enable the main body 2 and the outer shell to rotate slowly during the rotation process, a damping structure can be provided on the rotating shafts 27.

[0047] like Figure 5 As shown, a rotating support 172 is also provided in the middle of the mounting plate 121 between the two rotating seats 17, and at least one supporting surface 173 is formed on the upper side of the rotating support 172; correspondingly, as Figure 6As shown, at least one rotating support block 232 is provided at the bottom center of the inner front plate 23, between the two rotating legs 231. The bottom of the rotating support block 232 is semi-circular, and its center is coaxial with the rotating shaft 27. The bottom of the rotating support block 232 rotates and engages with the support surface 173, providing support for the rotation of the main body 2, sharing the load-bearing pressure of the rotating shaft 27, and increasing the strength and lifespan of the rotating structure. The support surface 173 can be arc-shaped or flat, preferably arc-shaped, so that the contact area with the rotating support block 232 is larger and the support effect is better.

[0048] The front cover 15 is installed over the front opening 141. Its inner side is connected to the inner front plate 23 of the main body 2 by a snap or fastener. The front cover 15 covers the outside of the rotating seat 17, the rotating shaft 27, and the rotating support block 232, forming an embedded and hidden internal rotating structure. To ensure the airtightness of the main body 2 in the closed state, a sealing element 4 is provided between the rear side of the inner front plate 23 and the front opening 141. The sealing element 4 is square. Sealing edges extend around the inner edge of the front opening 141. In this embodiment, the sealing edges extend to the outer top plate 11, the outer bottom plate 12, and the two outer side plates 13 near the front end, dividing the accommodating cavity 14 into two spaces. The rear space is larger and is used to accommodate the storage part of the main body 2. The front space is smaller and is used for the fitting of the inner front plate 23 and the front cover 15. The shape of the front cover 15 is consistent with the shape of the front opening. When the main body 2 is in the closed state, the front cover or the inner front plate is embedded in the front opening, making the overall appearance more aesthetically pleasing.

[0049] The sealing edge is recessed inward to form a sealing groove 1411. The sealing element 4 is embedded in the sealing groove 1411. By placing the sealing element 4 here, the end faces of the outer shell 1 and the main body 2 are completely fitted together, achieving a surface seal without dead angles and improving the sealing performance of the storage device.

[0050] like Figure 11 As shown, the bottom sealing groove 1411 and the rotating seat 17 are both located on the bottom sealing edge (i.e., mounting plate 121). The bottom sealing groove 1411 is located above the rotating seat 17, and a rotation clearance space is formed below the rotating seat 17. Since the front cover and inner front plate of this embodiment are embedded in the outer shell, the rotation clearance space can prevent the bottom of the front cover and inner front plate from interfering with the outer shell when rotating. This design can effectively solve the sealing problem and rotation interference problem of this type of embedded rotating structure.

[0051] like Figure 10As shown, the front cover plate 15 is provided with a force-applying part for changing the main body 2 from the closed state to the open state. In this embodiment, the force-applying part is an embedded handle 5 located at the upper part of the front cover plate 15, which has an inner side that extends into a receiving space and has a front stop. A long, narrow mounting hole 151 is provided near the top of the front cover plate 15. The embedded handle 5 protrudes inward to form an embedded body 51. A through hole 233 with a matching shape is provided on the inner front plate 23 corresponding to the mounting hole 151. The embedded body 51 is set through the through hole 233. At the same time, a front retainer 6 protruding towards the accommodating space is also installed at the through hole 233. The front retainer 6 can also be regarded as a front retainer. It is fitted around the outer periphery of the embedded body 51 and is used to fix the embedded body 51 to the main body 2. At the same time, the front retainer 6 is horizontally set on the upper part of the inner front plate 23. When the main body 2 is open, it blocks the items in the accommodating space 21, preventing them from falling out along the inner side of the inner front plate 23 when the main body is opened (especially when the items stored inside are granular foods such as rice and beans, they are easy to slide out and fall out if there is no obstruction).

[0052] In this embodiment, to prevent interference between the inner rear plate 24 and the outer shell 1 when the inner rear plate 24 rotates, the vertical height of the inner rear plate 24 of the main body 2 is set lower than the vertical height of the inner front plate 23. When the main body 2 rotates inward from the open state to the closed state, the internal items tend to move backward. To prevent the internal items from spilling out from the opening at the top of the main body 2 (i.e., the storage inlet 22), such as... Figure 6 and Figure 7 As shown, a blocking part 7 is integrally or separately provided on the inner rear plate 24 of the main body 2. In this embodiment, the blocking part 7 is separately provided on the upper rear side of the main body 22. Several downwardly recessed fixing grooves 222 are provided on the rear edge 221 of the storage inlet 22. A fixing plate 71 that can be embedded in the fixing groove 222 is formed at the lower edge of the blocking part 7. The fixing plate 71 is fixed in the fixing groove 222 by fasteners (such as screws or bolts). At the same time, several limiting holes 223 are also provided at the rear edge 221 of the storage inlet 22. A limiting plate 72 that can be inserted into the limiting hole 223 is formed at the edge of the blocking part 7 and is located diagonally below the fixing groove 222. The fixing groove 222 and the limiting hole 223 together form an upper and lower limit for the blocking part 7, which enhances the connection between the blocking part 7 and the main body 2 and prevents the blocking part 7 from falling off due to the impact of the blocked item being too heavy.

[0053] like Figure 7 As shown, the rear edge of the storage inlet is provided with several vertical reinforcing ribs to increase the installation strength of the blocking part 7.

[0054] The blocking part 7 is a long, strip-shaped, cap-like structure with bent ends, and has a baffle 73 that is combined with the inner rear plate 24, and side baffles 74 that are combined with the upper rear sections of the two inner side plates 26, such as... Figure 2 , Figure 6 and Figure 7 As shown, when the main body 2 is in the closed state, the baffle 73 and the inner rear plate 24 are arranged at an angle; Figure 11 As shown, when the main body 2 is in the open state, the baffle 73 is basically parallel to the outer top plate 11 of the housing 1. The housing 1 is provided with a retaining edge 1412 near the top of the front opening 141. A sealing groove 1411 for installing the sealing element 4 is formed on one side of the retaining edge 1412. When the main body 2 is in the open state, the front edge of the baffle 73 abuts against the retaining edge 1412, thereby blocking the main body 2.

[0055] To prevent the main body (including the items) from automatically closing due to the center of gravity being on the inside, a self-locking component is provided between the stop 1412 and the blocking part 7 to prevent the main body 2 from detaching from the housing when it is in the open state. That is, the self-locking component, the stop 1412 and the blocking part 7 form a rotation positioning mechanism. When the main body is in the open position, the blocking part and the stop can be positioned by the self-locking component, freeing the user's hands and making it convenient to pick up items.

[0056] In this embodiment, as Figures 11-13 As shown, the self-locking assembly is a push-button elastic latch, having a locking pin 81 formed on the retaining edge 1412 and a lock body 82 installed on the front edge of the baffle 73 of the blocking part 7. The lock body 82 has: a lock shell 821, a lock hook 822, a lock cylinder 823, and an elastic element (spring 824). A mounting hole is provided in the middle of the front edge of the baffle 73, and the lock shell 821 is fixed in the mounting hole. The lock hook 822 is installed in the lock shell 821. The front end of the lock cylinder 823 has a claw 8231 that extends out of the lock shell 821 and is used to cooperate with the locking pin 81, and a lock groove 8232 located inside the lock shell 821 and is used to cooperate with the lock hook 822. The spring 824 is installed between the lock cylinder 823 and the lock shell 821 and is used to act on the lock cylinder 823. The working principle of the push-button elastic latch is prior art and will not be described in detail here. When the main body 2 rotates outward, the pawl 8231 collidees with the locking pin 81 located on the stop edge, and the locking pin 81 can engage with the pawl 8231, thereby locking the main body 2 in the open state. When it is necessary to return to the closed state, first pull the main body 2 outward to unlock the self-locking component, and then push the main body 2 inward to rotate it back to the closed state, or the main body 2 can be reset to the closed state by its own weight.

[0057] like Figure 2 As shown, an installation space for mounting a buffer 3 is formed between the inner bottom plate 25 and the outer bottom plate 12 of the main body 2. The buffer 3 is a damping buffer or a spring buffer. Figure 4 As shown, a first mounting base 31 is provided on the side of the outer base plate 12 facing the inner base plate 25, such as... Figure 8 As shown, a second mounting base 32 is provided on the side of the inner bottom plate 25 facing the outer bottom plate 12. One end of the buffer 3 is mounted on the first mounting base 31, and the other end is mounted on the second mounting base 32. Specifically, as... Figure 4 As shown, at least one pair of protruding edges 122 protrude upwards on the side of the outer bottom plate 12 facing the inner bottom plate, and a mounting groove 123 is formed between the pair of protruding edges 122. A first mounting seat 31 is slidably mounted in the mounting groove 123. Figure 11 As shown, a limiting through hole 124 is provided at the bottom of the mounting groove 123, and a limiting protrusion 311 is provided on the bottom surface of the first mounting base 31 that can be embedded in the limiting through hole 124. The rear side of the limiting protrusion 311 is engaged with the inner wall of the limiting through hole 124; Figure 4 As shown, the first mounting base 31 is T-shaped with a bent structure on its side. A protruding edge 122, located at the front of the bent structure of the first mounting base 31, forms a blocking edge 125 that can abut against the bent structure on the side of the first mounting base 31. This blocking edge 125 and the limiting through hole 142 respectively limit the front and rear movement of the first mounting base 31. A foot pad 126 is also provided at the bottom of the outer base plate 12 corresponding to the limiting through hole 124, which can block and cover the limiting through hole 124. Figure 8 As shown, the inner bottom plate 25 has a pair of downwardly protruding edges 251 on the side facing the outer bottom plate 12, and the ends of the edges 251 form a second mounting base 32. In this embodiment, only one buffer 3 is provided, so its position is best set in the middle of the inner bottom plate 25 and the outer bottom plate 12. When the size of the main body 2 is large and the stored items are heavy, multiple buffers 3 can be provided and evenly distributed at the bottom. Since the installation space formed between the inner bottom plate 25 and the outer bottom plate 12 of the main body 2 is relatively limited, the sliding installation method of the first mounting base 31 is more convenient for installation. Specifically, during installation, the buffer 3 is first installed on the second mounting base 32, and then the first mounting base 31 is slid into the mounting groove along the two protruding edges 122 of the outer bottom plate 12 until the limiting protrusion 311 is engaged with the limiting through hole 124 to complete the installation.

[0058] In this embodiment, as Figure 2 and Figure 11As shown, the back cover 16 has a hollow, three-dimensional shape and includes a back cover body 161 and a cover plate 162. The back cover body 161 has a storage cavity 163 inside, which is open to the rear and front for storing items. The cover plate 162 is detachable or rotatable and covers the rear and front opening of the storage cavity 163. The storage cavity 163 can be used to store items, which can serve as a load-bearing component, such as placing water bags or counterweights, to prevent the main body 2 from tipping forward when opened due to excessive weight of the items stored inside. Furthermore, the storage cavity 163 can also be used to store desiccants, and it connects to the receiving cavity 14 of the outer shell 1, thus providing a drying effect for the items placed inside the main body 2.

[0059] The bottom of the outer top plate 12 is provided with a pair of front support legs 127 and a pair of rear support legs 128. The inner bottom plate 25 is provided with a pair of inner support legs 252 near the inner rear plate 24. The bottom of the rear cover body 161 is provided with a rear bottom support leg 164. When in the closed state, the inner support legs 252 and the rear support legs 128 are coaxially arranged, so that the support is on the same straight line and more evenly. A buffer pad is also provided between the bottom surface of the inner support leg 252 and the top surface of the outer bottom plate 12 to provide cushioning at the support legs when the main body 2 returns to the closed state. The front support legs 127, the rear support legs 128 and the bottom of the rear support legs 128 are all provided with support leg pads. A date reminder can also be provided on the outer shell 1 to record the date stored by the user.

[0060] <Example 2>

[0061] The difference between this embodiment and embodiment 1 above is that the force-applying part is a protruding handle 9 located on the upper part of the front cover plate 15, such as... Figure 15 As shown, the protruding handle 9 has a handle base 91 and a handle handle 92. A long strip-shaped mounting hole 151 is provided at the upper part of the front cover plate 15. The handle base 91 is installed at the mounting hole 151, and the handle handle 92 is installed on the handle base 91. A through hole 233 with a matching shape is provided on the inner front plate 23 corresponding to the mounting hole 151. The handle base 91 is set through the through hole 233 at the rear. At the same time, a handle base rear plate 93 is also installed at the through hole 233. The handle base 91 is fixedly installed by screws passing through the handle base rear plate 93 and inserting the handle handle 91 into the handle handle 91.

[0062] The handle base 91 or the handle base rear plate 93 can both be considered as the front stop in this embodiment. It is horizontally arranged on the upper part of the inner front plate 23. When the main body 2 is open, it blocks the items in the accommodating space 21, preventing them from falling out along the inner side of the inner front plate 23 when the main body is opened (especially when the items stored inside are granular foods such as rice and beans, they are easy to slide out and fall out if there is no obstruction).

[0063] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
