Description

Technical Field

[0001] This application relates to the field of storage technology, specifically to a storage rack and storage device. Background Technology

[0002] Storage racks are commonly used in kitchens to store spice jars, tableware, and other items. Sometimes, to save countertop space, people install storage racks under wall cabinets or hanging cabinets. However, these types of storage racks usually have exposed frames and lack dust and insect protection, resulting in less than ideal storage performance.

[0003] Patent application No. 201910706827.7 discloses a concealed bottom cabinet storage rack, including a shell, a connecting rod, a return spring, and a cover. The connecting rod connects the shell and the cover. When the cover is raised to its highest position, it closes the open window, transforming the concealed bottom cabinet storage rack into a shelving form for concealing the storage area. When the cover is lowered to its lowest position, it is located below the main shell, and its side facing the main shell forms a storage structure for placing items, transforming the concealed bottom cabinet storage rack into a shelf form for opening the storage area. However, in this shelf form, the return spring pulls the connecting rod, causing it to tend to return to its original position. A spring clip must be provided to fix the position of the connecting rod to maintain its fixed position. The technical solution provided in this patent application relies entirely on the limiting function of the spring clip in the shelf form. When the spring clip deforms and fails, the return spring pulls the connecting rod, causing the cover to return to its original position and switch back to the shelving form. This structural design exhibits generally poor durability and reliability, resulting in a poor user experience.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] like Figures 1 to 6 As shown, this application embodiment provides a storage rack, including: a storage shell 1, a movable linkage assembly 2, a shelf 3, and an elastic pusher 4. The storage shell 1 has a storage cavity 11 and an opening 12 communicating with the storage cavity 11. One end of the movable linkage assembly 2 is hinged to the storage shell 1, and the movable linkage assembly 2 can rotate around a first rotation axis. The hinge position of the movable linkage assembly 2 to the storage shell 1 is located on the first rotation axis. The shelf 3 is connected to the other end of the movable linkage assembly 2. One end of the elastic pusher 4 is hinged to the storage shell 1, and the other end is hinged to the movable linkage assembly 2. The storage rack has a first stable state and a second stable state. In the first stable state, as... Figures 1 to 3As shown, the shelf 3 is away from the storage shell 1, the elastic pusher 4 is in a retracted state, and the pushing direction of the elastic pusher 4 passes through the first rotation axis. In the second stable state, as... Figures 4 to 6 As shown, the elastic pusher 4 extends and pushes the movable connecting rod assembly 2 to rotate, so that the storage plate 3 covers the storage shell 1 and closes the opening 12.

[0023] The storage rack provided in this application can switch between a first stable state and a second stable state. During normal use, an external force can be applied to lower the shelf 3, switching to the first stable state. The storage rack then appears as a double-layered storage rack, with the upper layer being a storage cavity 11 enclosed by the storage shell 1, and the lower layer being a storage structure formed by the shelf 3, which can be used for temporary placement of items. When not in use, an external force can be applied directly to the shelf 3, causing the shelf 3 to close its opening 12, switching to the second stable state. This provides dust and insect protection, resulting in a neat and aesthetically pleasing appearance and achieving a more ideal storage effect.

[0024] The elastic pusher 4 may include a main rod and a push rod, with the push rod slidably connected to the main rod. The push rod has a tendency to extend out of the main rod (e.g., a spring exists between the push rod and the main rod). The elastic pusher 4 may be a spring push rod, a telescopic cylinder, or a hydraulic push rod, etc., and this application does not limit the specific structure of the elastic pusher 4.

[0025] In the first stable state, the elastic pusher 4 pushes through the first rotation axis, and the movable linkage 2 is in a self-locking state to prevent accidental deformation of the movable linkage 2. When switching to the second stable state, the storage rack can be stably in the first stable state without external interference. There is no need to set a locking structure for locking the movable linkage 2. The structure is simple, reliable, and durable.

[0026] When the storage rack is in its second stable state, it mainly relies on the pushing (elongation) action of the elastic pusher 4 to deform the movable linkage 2, causing the shelf 3 to move upward and close the opening 12 on the storage shell 1. The elastic pusher 4 is in an elongated state when there is no external force, and will shorten under the action of external force, but it is in an elastic compression state and has a tendency to elongate.

[0027] In some possible implementations, the movable linkage group 2 includes a first linkage 21 and a second linkage 22. One end of the first linkage 21 and the second linkage 22 are hinged to the storage shell 1, and the other end is hinged to the shelf 3. The first linkage 21 rotates about the first rotation axis, and the second linkage 22 rotates about the second rotation axis. The elastic pusher 4 is hinged to the first linkage 21.

[0028] The first connecting rod 21, the second connecting rod 22, the storage plate 3, and the storage shell 1 form a quadrilateral connecting rod structure, which can rotate and deform under the action of external force. A rotatable connecting part 211 is provided on the first connecting rod 21, which connects to the storage shell 1. A connecting hole can be provided on the rotatable connecting part 211, through which one end of a connector passes and connects to the storage shell 1, thereby hinged the second connecting rod 22 to the storage shell 1. This connector extends along the first rotation axis.

[0029] In some possible implementations, such as Figure 2 As shown, the first connecting rod 21 has a rotating connection part 211, a main rod section 212 and an extension rod section 213. The rotating connection part 211 is rotatably connected to the storage shell 1. The main rod section 212 and the extension rod section 213 are located on both sides of the rotating connection part 211. The main rod section 212 is connected to the storage plate 3, and the extension rod section 213 is connected to the elastic pusher 4.

[0030] In some possible implementations, the movable linkage 2 is disposed on the outer wall of the housing 1, and the extension rod segment 213 is provided with a connecting piece 2131 offset toward the housing cavity 11 on the side opposite to the main rod segment 212, and the elastic pusher 4 is hinged to the connecting piece 2131.

[0031] In this embodiment, by providing a connecting piece 2131 that is offset to one side of the storage cavity 11, it is convenient for the elastic pusher 4 to approach the storage cavity 11, which helps to reduce the size of the storage rack.

[0032] In some possible implementations, such as Figure 5 As shown, the storage rack includes a synchronizing rod 5. The movable connecting rod group 2 and the elastic pusher 4 are respectively arranged on both sides of the storage shell 1. The second connecting rods 22 of the movable connecting rod group 2 on both sides of the storage shell 1 are connected through the synchronizing rod 5. The rotation of one second connecting rod 22 can drive the other second connecting rod 22 to rotate synchronously through the synchronizing rod 5.

[0033] By setting the synchronizing rod 5, the second connecting rod 22 of the movable connecting rod group 2 on both sides is linked, so that the second connecting rod 22 of the movable connecting rod group 2 on both sides of the storage shell 1 rotates synchronously, so that the shelf 3 can be raised and lowered smoothly without tilting.

[0034] In some possible implementations, combined Figure 2 and Figure 3 As shown, the storage rack includes an auxiliary positioning seat 6, which is disposed on the storage shell 1. A positioning fitting 214 is disposed on the first connecting rod 21. In the first stable state, the positioning fitting 214 and the auxiliary positioning seat 6 are in a limiting fit. In the second stable state, the positioning fitting 214 and the auxiliary positioning seat 6 are separated.

[0035] The auxiliary positioning seat 6 is not a necessary structure of this application, but an optional structure. When the auxiliary positioning seat 6 is installed on the storage rack, the attitude of the movable linkage group 2 can be further restricted in the first stable state, thereby improving the reliability of the storage rack.

[0036] In some possible implementations, in the first stable state, the auxiliary positioning seat 6 locks the positioning mating part 214, fixing the attitude of the movable linkage group 2 and keeping the storage rack stable in the first stable state. Only when an external force is applied to the shelf 3 can the movable linkage group 2 rotate, and the storage rack return to the second stable state.

[0037] In some possible implementations, combined Figure 2 and Figure 3 As shown, a slot 61 is formed on the surface of the auxiliary positioning seat 6, and an elastic limiting component 63 is provided on the outer wall of the auxiliary positioning seat 6. A mating block 2141 is provided at the end of the positioning mating component 214. In the first stable state, the mating block 2141 is embedded in the slot 61, and the elastic limiting component 63 is limited to one side of the mating block 2141.

[0038] The auxiliary positioning seat 6 has a guide groove 62 and a slot communicating with the guide groove 62. The elastic limiting component 63 is located within the guide groove 62. The elastic limiting component 63 includes an elastic element 631 and a ball 632. The elastic element 631 elastically abuts against the ball 632, causing the ball 632 to at least partially extend out of the slot. In the first stable state, the ball 632 is limited to one side of the mating block 2141. The outer diameter of the ball 632 is larger than the inner diameter of the slot, and the partial extension of the ball 632 out of the slot serves to limit the positioning of the mating component 214.

[0039] During the transition from the second stable state to the first stable state, the positioning fitting 214 abuts against the ball 632, causing the ball 632 to retract into the slot. After the positioning fitting 214 rotates past the slot, it moves into the retaining groove 61. The ball 632 is reset by the abutment of the elastic member 631 and confined to one side of the positioning fitting 214, preventing it from moving in the opposite direction. The mating block 2141 can be a cylinder with a cylindrical surface, allowing for smooth contact and mating with the ball 632 without causing severe friction or scratches.

[0040] In some possible implementations, the storage rack includes a mounting plate 7 detachably mounted to the storage shell 1, with an accommodating gap between the mounting plate 7 and the storage shell 1, one end of an elastic pusher 4 located within the accommodating gap, and the elastic pusher 4 connected to the mounting plate 7 and the storage shell 1 via a shaft.

[0041] The mounting plate 7 facilitates the connection of the shaft through the elastic pusher 4 to the mounting plate 7 and the housing 1 respectively, and the two ends of the shaft can be stably and effectively supported, thus realizing the reliable assembly of the elastic pusher 4.

[0042] This application also provides a storage device, including: a cabinet and a storage rack, wherein the storage shell 1 of the storage rack is disposed at the bottom of the cabinet.

[0043] The cabinet can be a wall cabinet or a hanging cabinet, and the storage rack can be installed on the bottom surface of the cabinet. When needed, the shelf 3 can be moved to the first position, allowing the user to access items in the storage cavity 11 through the opening 12. When not in use, the shelf 3 can be moved to close the opening 12, thus providing some dust and insect protection, resulting in a neat and aesthetically pleasing appearance and achieving a relatively ideal storage effect.

[0044] In this embodiment, the lifting trajectory of the shelf 3 is an arc-shaped trajectory, which allows the shelf 3 to be positioned at its highest position, closing the opening 12 on the side of the storage shell 1. When the shelf 3 is at its lowest position, it is located directly below the storage shell 1, and at this time, the shelf 3 can be used to place objects.
