Description

Technical Field

[0001] The utility model belongs to the technical field of storage articles, in particular to a storage device. Background Art

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

[0003] For example, the rice storage bucket proposed in prior invention disclosure CN108143322A has a rice access bucket slidably disposed at the bottom, allowing rice to be taken out by moving the rice access bucket. However, since the storage entrance is located at the top and the top cover is provided with a lid, the lid must still be removed before the rice can be put in, which is not convenient. There are also some lids on the market that are rotatable, but when the lid is located at the top, it increases the vertical height after being rotated and folded. If the space for storing the rice bucket is low, the lid cannot be opened and the rice storage bucket is required to open the lid, which has certain limitations on the use environment.

[0004] Therefore, the applicant has set up a side-opening storage device, which includes an outer shell and a main body rotatably arranged on the outer shell. The main body is provided with a storage space. Since the center of gravity of the main body (including items) is affected by the weight and position of the items themselves, when the main body is opened, if the center of gravity of the main body (including items) is on the outside, the main body can maintain an open state. If the center of gravity of the main body (including items) is on the inside, it will automatically close, requiring the user to hold on to it all the time, making it inconvenient to take items.

[0045] <Example 1>

[0046] This embodiment provides a storage device, in particular a storage device for storing granular objects such as rice and soybeans. Figure 1-Figure 3 As shown, the storage device includes a shell 1 and a main body 2, the main body 2 is rotatably arranged in the shell 1, and the main body 2 has a storage space 21 for storing items and an entrance 22 for putting items in, wherein 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 entrance 22 is enclosed inside the housing 1, that is, the main body 2 is entirely located inside the housing 1; when in the open state, as shown in FIG. Figure 3 As shown, at least a portion of the storage entrance 22 is exposed from the housing 1, allowing a user to place items into or remove items from the storage space 21. A rotation mechanism is provided between the main body 2 and the housing 1. Driven by the rotation mechanism, the main body 2 can rotate relative to the housing, thereby switching the main body 2 between a closed state and an open state.

[0047] In this embodiment, the storage entrance 22 is located at the top of the accommodating space 21, that is, the main body 2 is a barrel-shaped structure with an upper opening, and its bottom is rotatably arranged on the housing 1 through a rotating mechanism, that is, the rotating mechanism is located at the bottom of the main body 2. Specifically, Figure 3-Figure 5As shown, the housing 1 includes a shell, a front cover 15 and a rear cover 16. The shell is 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 front and rear sides of the receiving cavity 14 respectively have a front opening 141 and a rear opening 142. The front cover 15 can be opened and closed at the front opening 141, and the rear cover 16 is set at the rear opening 142. Figure 6-Figure 8 As shown, the main body 2 is barrel-shaped, having an inner front plate 23, an inner rear plate 24, an inner bottom plate 25 and two inner side plates 26. A storage space 21 with a storage entrance 22 at the top is formed between the inner front plate 23, the inner rear plate 24, the inner bottom plate 25 and the two inner side plates 26. The inner front plate 23 is fixed on the front cover 15.

[0048] In this embodiment, in order to prevent the inner rear panel 24 from interfering with the outer shell 1 when rotating, the height of the inner rear panel 24 of the main body 2 in the vertical direction is set to be lower than the height of the inner front panel 23 in the vertical direction. When the main body 2 rotates inward from the open state to the closed state, the items inside will tend to move backward. In order to prevent the items inside from spilling out from the upper opening of the main body 2 (i.e., the storage entrance 22), as shown in FIG. Figure 6 and Figure 7 As shown, a blocking portion 7 is integrally or separately provided on the inner rear panel 24 of the main body 2. In this embodiment, the blocking portion 7 is separately provided on the upper rear side of the main body 22. A plurality of downwardly recessed fixing grooves 222 are provided on the rear edge 221 of the storage entrance 22. A fixing plate 71 is formed at the lower edge of the blocking portion 7, which is embedded in the fixing grooves 222. The fixing plate 71 is fixed in the fixing grooves 222 by fixing members (such as screws or bolts). At the same time, a plurality of limiting holes 223 are also provided on the rear edge 221 of the storage entrance 22. A limiting plate 72 is formed on the edge of the blocking portion 7, which is inserted into the limiting holes 223 and is located obliquely below the fixing grooves 222. The fixing grooves 222 and the limiting holes 233 together form upper and lower limits for the blocking portion 7, thereby enhancing the connection between the blocking portion 7 and the main body 2 and preventing the blocking portion 7 from falling due to the impact of the heavy objects being blocked.

[0049] like Figure 7 As shown, a plurality of vertical reinforcing ribs are provided on the rear edge of the storage entrance to increase the installation strength of the blocking portion 7.

[0050] The blocking portion 7 is a long, cap-like structure with bent ends, and has a baffle 73 combined with the inner rear plate 24, and a side baffle 74 combined with the upper rear sections of the two inner side plates 26. 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 obliquely; Figure 11 As shown, when the main body 2 is in the open state, the baffle 73 is substantially parallel to the outer top plate 11 of the housing 1. A baffle 1412 is provided at the top of the housing 1 near the front opening 141. A sealing groove 1411 for mounting the seal 4 is formed on one side of the baffle 1412. When the main body 2 is in the open state, the front edge of the baffle 73 abuts against the baffle 1412, thereby blocking the main body 2.

[0051] In order to prevent the center of gravity of the main body (including items) from automatically closing on the inside, a self-locking component is provided between the blocking edge 1412 and the blocking part 7 to prevent the main body 2 from detaching from the shell when in the open state, that is, the self-locking component, the blocking edge 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 blocking edge can be positioned by the self-locking component, freeing the user's hands and making it convenient to take items.

[0052] like Figure 16 As shown, the inner wall of the housing is provided with guide blocks 18 on both sides of the retaining edge 1412. The guide blocks 18 can guide both sides of the blocking portion 7 when the main body 2 is opened, so that the engagement and locking of the self-locking component is smoother, thereby improving the user experience. Figure 11-13 As shown, the self-locking component is a push-type elastic lock, which has a lock pin 81 formed on the blocking edge 1412 and a lock body 82 installed on the front edge of the baffle 73 of the blocking portion 7. The lock body 82 has: a lock shell 821, a lock hook 822, a lock core 823 and an elastic member (spring 824). A mounting hole is provided in the middle of the edge of the front side of the baffle 73, the lock shell 821 is fixed in the mounting hole, the lock hook 822 is installed in the lock shell 821, and the front end of the lock core 823 has a claw 8231 extending out of the lock shell 821 for cooperating with the lock pin 81 and a lock groove 8232 located inside the lock shell 821 for cooperating with the lock hook 822. The spring 824 is installed between the lock core 823 and the lock shell 821 for acting on the lock core 823. The working principle of the push-type elastic lock is the existing technology and will not be described in detail here. When the main body 2 rotates outward, the claw 8231 hits the lock pin 81 on the retaining edge, and the lock pin 81 can be locked into the claw 8231, thereby locking the main body 2 in the open state. To return to the closed state, the main body 2 is first pulled outward to unlock the self-locking assembly, and then pushed inward to rotate it back to the closed state, or the main body 2 can return to the closed state by its own weight.

[0053] The rotating mechanism of this embodiment is specifically as follows:

[0054] A rotating seat 17 is provided on the bottom of the front side of the housing (i.e., the front side of the outer bottom plate 12 at the front opening 141), and a rotating hole 171 is provided in the rotating seat 17. A rotating shaft 27 is provided on the bottom of the inner front plate 23 or the front side of the inner bottom plate 25 to rotate on the rotating hole 171. The rotation between the main body 2 and the housing is achieved by the cooperation between the rotating shaft 27 and the rotating hole 171. In this embodiment, as Figure 5 As shown, the front side of the outer bottom plate 12 extends upward from the front opening 141 to form a mounting plate 121. The left and right sides of the mounting plate 121 protrude outward near the ends to form a rotating seat 17 (left rotating seat and right rotating seat). The left rotating seat and the right rotating seat are respectively provided with a rotating hole 171 facing the left and right sides. Figure 6 As shown, the two ends of the bottom 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 the right rotating foot protrude toward the right and left sides respectively (i.e., the direction corresponding to the rotating hole 171) to form a rotating shaft 27. 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 shell to rotate slowly during the rotation process, a damping structure can be set on the rotating shaft 27.

[0055] like Figure 5 As shown, a rotation support seat 172 is provided between the two rotation seats 17 in the middle of the mounting plate 121, and at least one support surface 173 is formed on the upper side of the rotation support seat 172; correspondingly, as shown in FIG. Figure 6 As shown, at least one rotation support block 232 is located in the middle of the bottom of the inner front panel 23, between the two rotation legs 231. The bottom of the rotation support block 232 is semicircular, with the center of the circle coaxial with the rotation shaft 27. The bottom of the rotation support block 232 rotates in conjunction with the support surface 173 to support the rotation of the main body 2, sharing the load-bearing pressure of the rotation shaft 27 and increasing the strength and life of the rotation structure. While the support surface 173 can be arc-shaped or flat, an arc-shaped shape is preferred, as it increases the contact area with the rotation support block 232 and provides better support.

[0056] The front cover 15 is positioned over the front opening 141. Its inner side is secured to the inner front panel 23 of the main body 2 via snaps or fasteners. The front cover 15 obscures the outer sides of the rotating seat 17, the rotating shaft 27, and the rotating support block 232, forming an embedded, concealed internal rotating structure. To ensure the tightness of the main body 2 when closed, a square-shaped seal 4 is provided between the rear side of the inner front panel 23 and the front opening 141. A sealing edge extends around the inner edge of the front opening 141. In this embodiment, these sealing edges extend onto the outer top panel 11, the outer bottom panel 12, and the two outer panels 13 near the front, dividing the accommodating chamber 14 into two compartments: a larger rear compartment for accommodating the storage area of ​​the main body 2; and a smaller front compartment for interlocking the inner front panel 23 and the front cover 15. The shape of the front cover 15 matches the shape of the front opening. When the main body 2 is closed, the front cover or inner front panel fits into the front opening, enhancing the overall appearance.

[0057] The sealing edge is concave inward to form a sealing groove 1411, and the sealing member 4 is embedded in the sealing groove 1411. The sealing member 4 is arranged here so that the end faces of the 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.

[0058] like Figure 11 As shown, the bottom sealing groove 1411 and the rotating seat 17 are both provided on the bottom sealing edge (i.e., the mounting plate 121). The bottom sealing groove 1411 is located above the rotating seat 17, and a rotation avoidance space is formed below the rotating seat 17. Since the front cover and the inner front plate of this embodiment are both embedded in the outer shell, the rotation avoidance space can prevent the bottom of the front cover and the inner front plate from interfering with the outer shell during rotation. This design can effectively solve the sealing and rotation interference problems of this type of embedded rotating structure.

[0059] like Figure 10As shown, the front cover 15 is provided with a force-applying portion for changing the main body 2 from a closed state to an open state. In this embodiment, the force-applying portion is an embedded handle 5 arranged at the upper part of the front cover 15, the inner side of which extends into the accommodating space and forms a front stop. The front cover 15 is provided with a long strip mounting hole 151 at the top, and the embedded handle 5 protrudes inward to form an embedded body 51. A through hole 233 of a shape matching the mounting hole 151 is provided on the inner front plate 23, and the embedded body 51 is arranged through the through hole 233. At the same time, a front baffle 6 protruding toward the accommodating space is also installed at the through hole 233. The front baffle 6 can also be considered as a front baffle, which is sleeved on the outer periphery of the embedded body 51 and is used to fix the embedded body 51 on the main body 2; at the same time, the front baffle 6 is transversely arranged on the upper part of the inner front plate 23. When the main body 2 is in the open state, it blocks the items in the accommodating space 21 to prevent 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, if there is no obstruction, they are easy to slide out and fall).

[0060] In addition, a buffer 3 is provided between the shell 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, so as to prevent the main body 2 from instantly falling back to its original position due to its gravity, causing a strong impact sound, or even causing the storage device to shake.

[0061] like Figure 2 As shown, an installation space for installing 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 seat 31 is provided on the side of the outer bottom plate 12 facing the inner bottom plate 25. Figure 8 As shown, a second mounting seat 32 is provided on the side of the inner bottom plate 25 facing the outer bottom plate 12, and one end of the buffer 3 is mounted on the first mounting seat 31, and the other end is mounted on the second mounting seat 32. Specifically, as Figure 4 As shown, the outer bottom plate 12 is formed with at least one pair of convex edges 122 protruding upwards on one side facing the inner bottom plate, and a mounting groove 123 is formed between the pair of convex edges 122. The 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 which can be embedded in the limiting through hole 124 is provided on the bottom surface of the first mounting seat 31, and the rear side of the limiting protrusion 311 is clamped on the inner wall of the limiting through hole 124; Figure 4As shown, the first mounting seat 31 is T-shaped, with a bent structure on the side. The convex edge 122 is located on the front side of the bent structure of the first mounting seat 31 and is formed with a blocking edge 125 that can abut against the bent structure on the side of the first mounting seat 31. The blocking edge 125 and the limiting through hole 142 respectively form front and rear limits for the first mounting seat 31. The bottom of the outer bottom plate 12 is also provided with a foot pad 126 corresponding to the limiting through hole 124 to block and cover the limiting through hole 124. Figure 8 As shown, the inner bottom plate 25 has a pair of downwardly projecting flanges 251 on the side facing the outer bottom plate 12. The ends of the flanges 251 form a second mounting seat 32. In this embodiment, only one buffer 3 is provided, so its optimal location is midway between the inner bottom plate 25 and the outer bottom plate 12. However, if the main body 2 is larger and contains heavier items, multiple buffers 3 can be provided, evenly spaced throughout the bottom. Because the installation space between the inner bottom plate 25 and the outer bottom plate 12 of the main body 2 is relatively limited, the aforementioned sliding installation method using the first mounting seat 31 is more convenient. Specifically, during installation, the buffer 3 is first mounted on the second mounting seat 32. The first mounting seat 31 is then slid into the mounting groove along the two flanges 122 of the outer bottom plate 12 until the stop protrusions 311 engage the stop holes 124. This completes the installation.
