[0046] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.
[0047] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0048] In one embodiment, such as Figure 1As shown, this utility model proposes a shelf structure, including: a first shelf plate 10, a second shelf plate 20, a sliding assembly 30, and a crank lifting assembly 40;
[0049] The two inward-facing ends of the first shelf plate 10 are respectively slidably connected to sliding components 30. The inward-facing side of each sliding component 30 is connected to the fixed side of the crank lifting component 40, and the lifting side of each crank lifting component 40 is connected to the two ends of the corresponding second shelf plate 20.
[0050] The second shelf 20 is first pulled out or pushed in horizontally relative to the first shelf 10 by the sliding assembly 30, and then the second shelf 20 is raised or lowered relative to the first shelf 10 by the crank lifting assembly 40.
[0051] It should be noted that the first shelf 10 and the second shelf 20 proposed in this embodiment are preferably rectangular in shape; of course, the first shelf 10 and the second shelf 20 can also be other shapes that are convenient for placing items, which are not limited here.
[0052] Therefore, the second shelf 20 of this utility model is first pulled out completely horizontally relative to the first shelf 10 via the sliding assembly 30 (e.g., Figure 4 (As shown), then the second shelf 20 is lifted relative to the first shelf 10 by rotating the crank lifting assembly 40 (as shown). Figure 7 As shown in the figure, the shelf structure can be adjusted more stably through the cooperation of the sliding component 30 and the crank lifting component 40, so as to better place various items of different heights and volumes, improve the space utilization of the shelf structure, and meet the user's needs for space utilization.
[0053] Specifically, to ensure that the second shelf 20 can be better lifted or lowered relative to the first shelf 10 by means of the crank lifting assembly 40, such as Figure 2-3 As shown, the crank lifting assembly 40 includes a fixed base 411 and a crank 412;
[0054] The second shelf plate 20 has fixed seats 411 connected to both ends of the side facing the extraction direction. The two ends of the fixed seats 411 are respectively hinged to one end of the crank 412, and the other end of the crank 412 is correspondingly hinged to the side of the sliding assembly 30 facing the extraction direction.
[0055] It should be noted that the fixing base 411 proposed in this embodiment is preferably a "∟" shaped plate.
[0056] When the user needs to raise the second shelf 20, the fixing seat 411 of the second shelf 20 will drive the crank 412 to rotate until the second shelf 20 reaches the specified height, at which point the crank 412 will stop rotating.
[0057] Furthermore, to prevent the second shelf 20 from continuing to rotate after reaching the designated height, thus affecting the stability of the items placed on the second shelf 20, such as... Figure 4 and 6 As shown, the second shelf 20 is located below the first shelf 10;
[0058] The first shelf 10 has slots 111 at both ends of the side facing the pull-out direction; the second shelf 20 has blocks 211 at both ends of the side facing the push-in direction.
[0059] When the second shelf 20 is fully pulled out and fully raised relative to the first shelf 10, the locking block 211 can be matched and engaged with the corresponding locking slot 111.
[0060] Understandably, when the second shelf 20 is fully extended relative to the first shelf 10 and the second shelf 20 is raised to the specified height (equivalent to the second shelf 20 being fully raised relative to the first shelf 10), the locking block 211 is flush with the corresponding locking slot 111. The user only needs to gently push the second shelf 20 in, and the locking block 211 of the second shelf 20 can match and engage with the corresponding locking slot 111, thereby playing a limiting support role. This prevents the second shelf 20 from continuing to rotate after reaching the specified height, which would cause the crank 412 to rotate too much, thus improving the stability of the shelf structure during the lifting or lowering process.
[0061] In a further embodiment, such as Figure 2-3 As shown, the crank lifting assembly 40 also includes an elastic body 413; and the elastic body 413 proposed in this embodiment is preferably a compression spring.
[0062] One end of an elastic body 413 is connected to the hinge between the crank 412 and the fixed seat 411 near the pull-out direction, and the other end of the elastic body 413 is connected to the hinge between the crank 412 and the sliding assembly 30 near the push-in direction.
[0063] Understandably, when the second shelf 20 is raised, it gradually rises relative to the first shelf 10 until it reaches its highest point. During this raising process, when the second shelf 20 is not raised, the elastic body 413 is in a compressed state (the compressed state means that the elastic body 413 has undergone elastic deformation, the same applies throughout the text). When the second shelf 20 begins to rise, the elastic body 413 will change from the initial compressed state to the normal state (the normal state means that the elastic body 413 has not undergone elastic deformation, the same applies throughout the text), indicating that the second shelf 20 has begun to rise. Then, the locking block 211 has matched and engaged with the corresponding locking slot 111, indicating that the second shelf 20 has been fully raised. At this time, the elastic body 413 will change from the normal state back to the compressed state. Of course, when the second shelf 20 descends relative to the first shelf 10 to return to its original position, the elastic body 413 also changes from the initial compressed state to the normal state, and finally returns to the compressed state.
[0064] In this way, during the lifting or lowering process, the second shelf 20 can be assisted by the small-range thrust generated when the elastic body 413 changes from the compressed state to the normal state, thereby ensuring that the second shelf 20 is lifted or lowered more smoothly (or more effortlessly).
[0065] Furthermore, to ensure the stability of the second shelf 20 during the lifting or lowering process, and to ensure that the items placed on the second shelf 20 do not fall or tip over during the lifting or lowering process, all the cranks 412 are located on the same plane and parallel to each other during the lifting or lowering process.
[0066] Understandably, the fixed base 411 remains horizontal throughout the lifting or lowering process.
[0067] In order to prevent the crank 412 from rotating too much and affecting the stability of the shelf structure during the lifting or lowering process, the rotation angle of all the cranks 412 is no greater than 90°.
[0068] In some embodiments, to ensure that the second shelf 20 can be better pulled out or pushed in relative to the first shelf 10 via the sliding assembly 30, such as Figure 1-2 As shown, the sliding assembly 30 includes a slide rail base 311 and a slide rail 312;
[0069] Both ends of the side of the first shelf board 10 facing the second shelf board 20 extend downward to form mounting seats (not shown, the same throughout the text), and a slide rail seat 311 is fitted and installed on the inner side of each mounting seat. A slide rail 312 is slidably connected within the slide rail seat 311. One ends of the slide rails 312 facing the extraction direction are respectively hinged to the other ends of all the cranks 412, and then one ends of all the cranks 412 are respectively hinged to the two ends of the fixed seat 411. The two fixed seats 411 are also bolted to the two ends of the side of the second shelf board 20 facing the extraction direction.
[0070] It should be noted that the slide rail seat 311 proposed in this embodiment is preferably a "C"-shaped plate.
[0071] Therefore, when the user needs to extract or push in the second shelf board 20 relative to the first shelf board 10, the second shelf board 20 can slide relative to the slide rail seat 311 through the slide rails 312, thereby achieving the extraction or pushing in of the second shelf board 20.
[0072] Among them, to further improve the sliding smoothness or silkiness of the slide rail 312 on the corresponding slide rail seat 311, as Figure 4-5 shown, first sliding grooves 313 are provided on the top wall and / or bottom wall of the slide rail 312 along the extraction direction. Matching second sliding grooves 314 are provided on the inner top wall and / or inner bottom wall of the slide rail seat 311 corresponding to the first sliding grooves 313. A sliding member 315 is placed in a matching manner between the second sliding grooves 314 and the corresponding first sliding grooves 313.
[0073] It can be understood that the sliding member 315 in this embodiment is preferably a ball. Of course, the sliding member 315 can also be other components that facilitate sliding, which are not limited herein.
[0074] Therefore, when the second shelf board 20 is extracted or pushed in relative to the first shelf board 10, the first sliding grooves 313 can slide relative to the second sliding grooves 314 through the sliding members 315, thereby achieving a smoother extraction or pushing in of the second shelf board 20 relative to the first shelf board 10, reducing the wear of the second shelf board 20 during the extraction or pushing in process, and thus extending the service life of the shelf structure.
[0075] In a further embodiment, to prevent the second shelf board 20 from falling off the first shelf board 10 during the process of extracting the second shelf board 20 relative to the first shelf board 10, which affects the structural stability and assembly reliability of the shelf structure, as Figure 8-9 shown, a limiting portion 316 is provided at the end of the second sliding groove 314 facing the extraction direction.
[0076] When the sliding member 315 abuts against the limiting part 316, the second shelf plate 20 is completely pulled out relative to the first shelf plate 10, and a gap space (not shown, same throughout) is formed between the second shelf plate 20 and the first shelf plate 10 in the pulling direction. This ensures that there is enough space for the crank lifting assembly 40 to move when the second shelf plate 20 is raised or lowered relative to the first shelf plate 10.
[0077] In another embodiment, such as Figure 10 As shown, this utility model also proposes a refrigerator, which includes at least one shelf structure as described above.
[0078] Understandably, when there are two or more shelf structures, all shelf structures are vertically arranged and spaced apart inside the refrigerator, and the distance between two adjacent shelf structures is large enough to allow sufficient space for the corresponding second shelf to be raised or lowered.
[0079] Therefore, as Figure 3-4 As shown in Figure 7, the first shelf 10 proposed in this embodiment is fixedly connected to the side wall inside the refrigerator along its length on both sides. Then, the two opposite ends of the first shelf 10 facing inward are respectively provided with slide rail seats 311. Slide rails 312 are slidably connected in the slide rail seats 311. The side of the slide rails 312 facing the pull-out direction is respectively hinged to the other end of the two cranks 412. One end of the elastic body 413 is connected to the hinge point of one of the cranks 412 near the pull-out direction and the fixed seat 411. The other end of the elastic body 413 is connected to the hinge point of the other crank 412 near the push-in direction. Then, one end of the two cranks 412 is respectively hinged to the two ends of the fixed seat 411. The two fixed seats 411 are also bolted to the two ends of the second shelf 20 facing the pull-out direction.
[0080] Therefore, in this embodiment, the slide rail 312 of the second shelf 20 is first completely horizontally pulled out through the slide rail seat 311 of the first shelf 10. Then, the second shelf 20 is lifted relative to the first shelf 10 by the crank 412, so that the shelf structure can be adjusted more stably to better place various items of different heights and volumes, improve the space utilization rate inside the refrigerator, and meet the user's needs for space utilization.
