Description

Technical Field

[0001] The utility model belongs to the technical field of storage containers and relates to a rotating tray storage rack. Background Art

[0002] As modern homes and businesses increasingly demand more efficient space, managing the internal space of storage devices like refrigerators, freezers, and cabinets has become increasingly important. Traditional fixed shelving systems present significant challenges when accessing deep or hard-to-reach items. This is particularly true in refrigerators and freezers, where users often need to remove items at the front before reaching the back. This is not only time-consuming and labor-intensive, but can also lead to items falling or becoming damaged.

[0003] Based on the above situation, rotating tray racks came into being. Rotating tray racks improve the utilization efficiency and access convenience of storage space by introducing a compound motion of rotation and translation. However, due to their own structural design reasons, existing rotating tray racks of this type are not stable enough during the rotation and translation motion process, so there is room for improvement. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the prior art and to propose a rotating tray storage rack.

[0005] The objectives of the utility model can be achieved through the following technical solutions: A rotating tray storage rack, comprising: a base and a tray, the tray being rotatably and translationally mounted on the base at the same time, the base being provided with a linear slide, a first guide track groove and a second guide track groove, the first guide track groove and the second guide track groove being symmetrically arranged with the linear slide as the axis of symmetry, the tray being provided with a rotating axis, a first guide axis and a second guide axis on a side facing the base, the rotating axis being slidably and rotatably mounted on the linear slide at the same time, the first guide axis being movably mounted on the first guide track groove, and the second guide axis being movably mounted on the second guide track groove.

[0006] Preferably, a sliding and rotatable translation rolling element is provided in the linear slide groove, and the rotation shaft is fixedly connected to the translation rolling element.

[0007] Preferably, a first guide roller that can slide and rotate is provided in the first guide track groove, a second guide roller that can slide and rotate is provided in the second guide track groove, the first guide shaft is connected to the first guide roller, and the second guide shaft is connected to the second guide roller.

[0008] Preferably, the travel position of the pallet includes a starting position, an expanded position and an end position; when the pallet is at the starting position or the end position, the rotating axis is at the rear limit position of the linear slide; when the pallet is at the expanded position, the rotating axis is at the front limit position of the linear slide; when the pallet moves from the starting position or the end position to the expanded position, the rotating axis slides from the rear limit position of the linear slide to the front limit position.

[0009] Preferably, the angular travel of the tray from the starting position to the end position is 180°, and the angular travel of the tray from the starting position or the end position to the unfolded position is 90°.

[0010] Preferably, when the tray moves, the movement trajectories of the first guide shaft and the second guide shaft are opposite.

[0011] Preferably, when the tray is located at the starting position or the end position, the first guide shaft is located at one of the beginning and the end of the first guide track groove, and the second guide shaft is located at the other of the beginning and the end of the second guide track groove.

[0012] Preferably, a first limit buckle is provided at the head end or tail end of the first guide track groove, and a second limit buckle is provided at the head end or tail end of the second guide track groove. The first limit buckle and the second limit buckle are symmetrically arranged with the linear slide groove as the symmetry axis.

[0013] Preferably, the first limiting buckle includes two first clamping springs respectively located on two side walls of the first guide track groove, and the second limiting buckle includes two second clamping springs respectively located on two side walls of the second guide track groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By setting two symmetrical guide track grooves on the base and correspondingly installing the first guide shaft and the second guide shaft on the tray, the stability and accuracy of the tray during rotation and translation are effectively guaranteed, avoiding shaking and deviation during movement.

[0016] 2. The translation roller not only slides within the linear groove but also rotates around its own axis, reducing friction and improving the smoothness of movement. Linear contact prevents lateral movement during sliding, ensuring stable movement. The guide roller design significantly reduces friction during the tray's rotation and translation, making the entire movement smoother and enhancing operational convenience and user experience.

[0017] 3. Since there is always a guide shaft located at the head end of its corresponding guide track groove and the other guide shaft located at the tail end of its corresponding guide track groove when the pallet is at the starting position or the end position, one of the guide shafts must be caught by the limit buckle of the corresponding guide track groove, thereby locking the pallet to limit the movement of the pallet. This structure enables the pallet to be locked at the starting position and the end position by the limit buckle to limit its rotation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1-6As shown, a rotating tray storage rack includes: a base 100 and a tray 200, the tray 200 can be simultaneously rotatably and translationally installed on the base 100, the base 100 is provided with a linear slide 110, a first guide track groove 120 and a second guide track groove 130, the first guide track groove 120 and the second guide track groove 130 are symmetrically arranged with the linear slide 110 as the symmetry axis, and the tray 200 facing the base 100 is provided with a rotating shaft 210, a first guide shaft 220 and a second guide shaft 230, the rotating shaft 210 can be simultaneously slidably and rotatably installed on the linear slide 110, the first guide shaft 220 can be movably installed on the first guide track groove 120, and the second guide shaft 230 can be movably installed on the second guide track groove 130.

[0027] In this embodiment, the combination of translational and rotational motion of the tray 200 is achieved through the cooperation between the rotating shaft 210 and the linear guide slot 110, as well as the cooperation between the first and second guide shafts 230 and their respective guide track slots. The tray 200 is preferably a square, disc-shaped structure. As it moves outward, the tray 200 can change its angular position. For example, the tray 200 is horizontal at its starting and ending positions and vertical in its extended position. This design, by changing the angular position of the tray 200, makes it easier for users to place and retrieve items.

[0028] Specifically, the first guide shaft 220 and the second guide shaft 230 are eccentric relative to the rotation center (rotation axis 210) of the tray 200. That is, they are not directly below or directly above the rotation axis 210, but are offset by a certain distance. The base 100 is provided with a first guide track groove 120 and a second guide track groove 130, which mate with the first guide shaft 220 and the second guide shaft 230. The design of the first guide track groove 120 and the second guide track groove 130 ensures the movement path of the first guide shaft 220 and the second guide shaft 230, thereby forcing the tray 200 to translate along a predetermined path during rotation.

[0029] The rotating tray rack is suitable for installation in a refrigerator. In this example, the base 100 is fixedly connected to the refrigerator's storage plate via suction cups, ensuring the stability of the entire device within the refrigerator. The tray 200 not only rotates around the rotation axis 210, but also slides along the linear slide 110 during rotation. This means that the rotation axis of the tray 200 is dynamically changing, gradually moving forward as the tray 200 rotates. Since the rotation axis of the tray 200 moves forward during rotation, this effectively prevents the tray 200 from colliding with the rear wall of the refrigerator during rotation, ensuring that the tray 200 can smoothly complete the entire rotation movement.

[0030] By setting two symmetrical guide track grooves on the base 100 and correspondingly installing the first guide shaft 220 and the second guide shaft 230 on the tray 200, the stability and accuracy of the tray 200 during rotation and translation movement are effectively guaranteed, avoiding shaking and deviation during movement.

[0031] On the basis of the above embodiment, a sliding and rotatable translation rolling element 140 is provided in the linear slide 110 , and the rotating shaft 210 is fixedly connected to the translation rolling element 140 .

[0032] In this embodiment, the translation roller 140 is fixedly connected to the rotating shaft 210 by screws. Preferably, the translation roller 140 is designed to be a roller-like structure, and its circumferential surface is connected to the two side walls of the linear slide 110 by line contact. The translation roller 140 can not only slide in the linear slide 110, but also rotate around its own axis, thereby reducing friction and improving the smoothness of movement. In addition, the line contact ensures that the translation roller 140 will not move laterally during the sliding process and maintain a stable motion state.

[0033] Based on the above embodiment, a first guide roller 150 that can slide and rotate is provided in the first guide track groove 120, a second guide roller 160 that can slide and rotate is provided in the second guide track groove 130, the first guide shaft 220 is connected to the first guide roller 150, and the second guide shaft 230 is connected to the second guide roller 160.

[0034] The first and second guide rollers 150, 160 are typically in the form of wheels or rollers. They not only slide within their respective guide grooves but also rotate about their axes, thereby reducing friction and improving smoothness of movement. The connection between the first and second guide shafts 220, 230 and their corresponding guide rollers ensures stability and precision during the movement of the tray 200, preventing wobble and deviation.

[0035] like Figure 1-6 As shown, based on the above embodiment, the travel position of the tray 200 includes a starting position, an expanded position and an end position. When the tray 200 is at the starting position or the end position, the rotating shaft 210 is located at the rear limit position of the linear slide 110. When the tray 200 is at the expanded position, the rotating shaft 210 is located at the front limit position of the linear slide 110; when the tray 200 moves from the starting position or the end position to the expanded position, the rotating shaft 210 slides from the rear limit position of the linear slide 110 to the front limit position.

[0036] This embodiment defines three key travel positions of the tray 200 (starting position, deployed position, and end position). When the tray 200 is at the starting position or the end position, the rotation axis 210 is at the rear limit position of the linear slide 110. At this time, the angular position of the tray 200 is 0° or 180°, and the tray 200 is close to the rear wall of the refrigerator, allowing the tray 200 to be stored inside the refrigerator to improve space utilization. When the tray 200 is in the deployed position, the rotation axis 210 is at the front limit position of the linear slide 110. At this time, the angular position of the tray 200 is 90°. Since the rotation axis 210 moves forward, the tray 200 does not touch the rear wall of the refrigerator.

[0037] Based on the above embodiment, the angular travel of the tray 200 from the starting position to the end position is 180°, and the angular travel of the tray 200 from the starting position or the end position to the unfolded position is 90°.

[0038] like Figure 1-5 As shown, based on the above embodiment, when the tray 200 moves, the movement trajectories of the first guide shaft 220 and the second guide shaft 230 are opposite.

[0039] Based on the above embodiment, when the tray 200 is at the starting position or the end position, the first guide shaft 220 is located at one of the beginning or the end of the first guide track groove 120, and the second guide shaft 230 is located at the other of the beginning or the end of the second guide track groove 130.

[0040] It's important to note that the positions of the first guide shaft 220 and the second guide shaft 230 are not symmetrical about the linear guide slot 110. As the tray 200 rotates from its starting position to its final position, one guide shaft slides from the leading end to the trailing end of its corresponding guide slot, while the other guide shaft slides from the trailing end to the leading end. This means that regardless of whether the tray 200 is in the starting position or the final position, one guide shaft is always located at the leading end of its corresponding guide slot, while the other guide shaft is always located at the trailing end of its corresponding guide slot.

[0041] Based on the above embodiment, a first limit buckle 121 is provided at the head end or tail end of the first guide track groove 120, and a second limit buckle 131 is provided at the head end or tail end of the second guide track groove 130. The first limit buckle 121 and the second limit buckle 131 are symmetrically arranged with the linear slide groove 110 as the symmetry axis.

[0042] Since when the tray 200 is at the starting position or the end position, there is always a guide shaft located at the head end of its corresponding guide track groove, and the other guide shaft is located at the tail end of its corresponding guide track groove, so there must be a guide shaft (guide roller) that is clamped by the limit buckle of the corresponding guide track groove, thereby locking the tray 200 to limit the movement of the tray 200. This structure enables the tray 200 to be locked at the starting position and the end position by the limit buckle to limit its rotation.

[0043] Based on the above embodiment, the first limiting buckle 121 includes two first clamping springs respectively located on the two side walls of the first guide track groove 120 , and the second limiting buckle 131 includes two second clamping springs respectively located on the two side walls of the second guide track groove 130 .

[0044] When the tray 200 is at the starting position and the end position, the first clamping spring and the second clamping spring can use their elastic properties to tightly clamp the first guide shaft 220 (first guide roller 150) and the second guide shaft 230 (second guide roller 160), providing a physical limit at the starting position and the end position.

[0045] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0046] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0047] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0048] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0049] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
