Description

Technical Field

[0001] This utility model relates to the technical field of shelving, and in particular to a sliding shelf. Background Technology

[0002] In the warehousing, logistics, and retail industries, shelving units are common equipment used for storing and displaying goods. Their structure typically consists of a support frame composed of four mounting columns. Multiple shelving units are horizontally arranged along the height of this frame within the support structure, with sufficient vertical space between the shelving units to facilitate the access and retrieval of goods. During installation, the shelving units are fixedly connected to the support frame structure, resulting in a fixed height between the shelving units.

[0003] However, excessive spacing between shelves leads to wasted upper-level space on each shelf, especially when storing small or low-profile goods. This prevents full utilization of vertical storage space, necessitating the addition of more shelves and increasing storage density. Secondly, retrieving items located at the back of the shelf requires reaching into the shelf, sometimes knocking over other goods and making retrieval difficult. Furthermore, organizing goods on the shelf requires pushing them outwards until they are close to the guardrail behind the shelf, making organization cumbersome. Utility Model Content

[0004] To overcome the technical problems of insufficient vertical storage space in existing shelves, difficulty in retrieving goods deep within the shelves, and cumbersome organization, this utility model provides a sliding shelf, including a frame with an enclosing cavity open in a first direction; a shelf body slidably connected to the inner walls of both sides of the enclosing cavity along the extension direction of the first direction, the shelf body having a first position and a second position relative to the frame; a limiting structure disposed along a second direction perpendicular to the first direction, the limiting structure being connected to the frame and to the left and right side walls of the shelf body, the limiting structure being used to limit the shelf body from displacement relative to the frame in a third direction; the shelf body located in the first position is housed in the enclosing cavity, and the shelf body located in the second position is at least partially located outside the enclosing cavity along the first direction.

[0005] Furthermore, it also includes a slider disposed in the frame along the first direction of the frame, the slider being used to drive the shelf body to translate along the first direction.

[0006] Furthermore, the inner wall surfaces of the frame on opposite sides are provided with grooves along the first direction, and the two sides of the shelf body are embedded in the grooves.

[0007] Furthermore, the chute has an upper chute wall and a lower chute wall, which are arranged opposite to each other to form the limiting structure.

[0008] Furthermore, the sliding member includes a plurality of balls, which are arranged at intervals in the inner cavity of the frame. The balls communicate with the slide groove, and the spherical surfaces of the balls exposed in the slide groove form the upper groove wall and the lower groove wall in the third direction.

[0009] Furthermore, the sliding member also includes several bearings, which pass through the ball bearings, and the two ends of the bearings are fixedly connected to the sidewall of the inner cavity.

[0010] Furthermore, it also includes a flange, which is fixed to the top ends of opposite sides of the frame in the first direction of the frame to form the opening end of the enclosing cavity.

[0011] Furthermore, the frame has a strip-shaped structure and includes two frames, which are parallel and opposite to each other in their extension direction in the second direction, forming the two side walls of the enclosing cavity.

[0012] Furthermore, it also includes a sliding rail, the shelf body is fixedly connected to the sliding rail, and the sliding rail is arranged facing the first direction. Beneficial effects

[0013] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0014] By pre-setting the maximum height of the stored items, four mounting columns form a support frame structure for installing the sliding shelf. The frames of the sliding shelf are arranged at intervals along the height of the support frame structure. The interval between the sliding frames is equal to the maximum height of the stored items, with a 0.5cm-1cm clearance reserved at this maximum height to facilitate the shelf body's movement back and forth between the first and second positions in the first direction of extension. This fully utilizes the vertical storage space of the shelf, and the distance between the sliding shelves is smaller than that between shelves in existing technologies. The sliding shelves can be installed relatively densely. Limiting structures are installed on the inner walls of both sides of the frame's containment cavity. After installation, the shelf body is inserted into the frame's containment cavity in sequence. The limiting structures are in contact with the upper and lower sides of the left and right side walls of the shelf body, but do not prevent the shelf body from moving back and forth along the length of the inner walls of the frame's containment cavity. This avoids the technical problems of difficulty in taking out and organizing goods protruding from the shelf in the prior art. When organizing and taking out goods, you only need to move the sliding shelf to the second position. After taking out and organizing, you can move the sliding shelf to the first position, giving users a good product experience. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] It should be noted that in this application, the first direction is represented by X; the second direction is represented by Y; and the third direction is represented by Z. The first direction, the second direction, and the third direction are mutually perpendicular. The first direction is the sliding direction of the shelf. The first direction X and the second direction Y form an XY plane. The third direction is a vertical direction perpendicular to the XY plane.

[0025] Please refer to Figures 1 to 5 A sliding shelf includes a frame 1 having an enclosing cavity 101 open in a first direction; a shelf body 2 slidably connected to the inner walls of both sides of the enclosing cavity 101 along the extension direction of the first direction, the shelf body 2 having a first position and a second position relative to the frame 1; a limiting structure disposed along a second direction perpendicular to the first direction, the limiting structure being connected to the frame 1 and to the left and right side walls 20 of the shelf body 2, the limiting structure being used to limit the shelf body 2 from displacement relative to the frame 1 in a third direction; the shelf body 2 located in the first position is housed in the enclosing cavity 101, and the shelf body 2 located in the second position is at least partially located outside the enclosing cavity 101 along the first direction.

[0026] In this technical solution, the frame 1 has a cavity 101, with one side of the frame 1 open as the opening end of the cavity 101. The cavity 101 is located in the first direction. The shelf body 1 is slidably connected to the inner walls of both sides of the cavity 101 along the extension direction of the first direction, so that the shelf body 1 has a first position and a second position relative to the frame 1. The frame 1 is connected to a limiting structure in the second direction. The limiting structure is connected to the left and right side walls 20 of the shelf body 2 to limit the displacement of the shelf body 2 relative to the frame 1 in the third direction, so that the shelf body 2 can be stably translated in the first direction, while ensuring the degree of freedom of the shelf body 2 in the first and second directions. The translation of the shelf body 2 is smooth and without jamming.

[0027] By pre-setting the maximum height of the stored items, four mounting columns form a support frame structure for installing the sliding shelf. The frames 1 of the sliding shelf are arranged at intervals along the height of the support frame structure. The interval between the sliding frames 1 is equal to the maximum height of the stored items, with a 0.5cm-1cm clearance reserved at this maximum height to allow the shelf body 2 to slide back and forth between the first and second positions in the first direction of extension. This fully utilizes the vertical storage space of the shelf. The distance between the sliding shelves is smaller than that between shelves in existing technology. To ensure a relatively dense installation, limiting structures are installed on the inner walls of both sides of the enclosure cavity 101 of frame 1. After installation, shelf bodies 2 are inserted into the enclosure cavity 101 of frame 1 in sequence. The limiting structures are in contact with the upper and lower sides of the side walls 20 on both sides of the shelf body 2, but this does not prevent the shelf body 2 from moving back and forth along the length of the inner walls of the enclosure cavity 101 of frame 1. This avoids the technical problems of difficulty in taking out and organizing goods protruding from the shelf in the prior art. When organizing and taking out goods, it is only necessary to move the sliding shelf to the second position. After taking out and organizing, the sliding shelf is moved to the first position, giving users a good product experience.

[0028] Depend on Figure 3 and Figure 5 As shown, it also includes a slider 3, which is disposed in the frame 1 along the first direction. The slider 3 is used to drive the shelf body 2 to translate along the first direction. In this embodiment, when the shelf body 2 is pushed or pulled, the slider 3 will drive the shelf body 2 to translate in the first direction, and the pushing and pulling is smooth and without jamming.

[0029] Depend on Figure 4 and Figure 5 As shown, the inner wall surfaces of opposite sides of the frame 1 are provided with grooves 12 along its first direction. The two sides of the shelf body 2 are embedded in the grooves 12, ensuring a stable connection between the shelf body 2 and the frame 1. A specific embodiment of the frame 1 is described below. Figure 5 As shown, the frame 1 has a strip-shaped structure and is provided with two frames 1. The two frames 1 are parallel and opposite to each other in their extension direction in the second direction, forming the two side walls of the enclosing cavity 101, which saves material costs and is easy to install.

[0030] It is worth noting that the specific implementation of the limiting structure is provided by... Figure 4As shown, the chute 12 has an upper chute wall and a lower chute wall, which are arranged opposite to each other to form the limiting structure. In this embodiment, the upper and lower chute walls of the chute 12 are arranged parallel to each other and are located on the upper and lower sides of the shelf body 2, forming a slide rail channel that allows the shelf body 2 to move from a first position to a second position or from a second position to a first position. The distance between the upper and lower chute walls determines the thickness of the side wall 20 of the shelf body 1, which plays a limiting role in the third direction, preventing the shelf body 2 from shaking or tilting downwards during translation, thus avoiding the defect of goods falling off the shelf and providing users with a good product experience.

[0031] The assembly relationship between the sliding member 3 and the groove 12 is as follows: Figure 3 and Figure 5 As shown, the sliding member 3 includes a plurality of ball bearings 31, which are spaced apart and arranged in the inner cavity 11 of the frame 1. The ball bearings 31 communicate with the slide groove 12. The spherical surfaces of the ball bearings 31 exposed in the slide groove 12 form the upper groove wall and the lower groove wall in the third direction. The distance between the upper groove wall and the lower groove wall determines the thickness of the shelf body 1, which serves as a limiting function in the third direction. This prevents the shelf body 2 from swaying or tilting downwards during translation, thus avoiding the defect of goods falling off the shelf and providing users with a good product experience.

[0032] Furthermore, the assembly relationship between the sliding component 3 and the frame 1 is determined by... Figure 5 As shown, the sliding member 3 also includes several bearings 32, which pass through the balls 31. The two ends of each bearing 32 are fixedly connected to the sidewall of the inner cavity 11. The bearings 32 penetrate the center of the balls 31, and their ends are fixed to the sidewall of the inner cavity 11, supporting and positioning the balls 31. The two ends of the bearings 32 are fixed to the sidewall by bolts, ensuring axial stability. The bearings 32 penetrate to the center of the balls 31, leaving gaps between them. These gaps ensure the rotation of the balls 31 while preventing them from shifting. The installation positions of the multiple bearings 32 in the first direction of the frame 1 are consistent, ensuring that the balls 31 are on the same horizontal plane in the first direction.

[0033] In order for the shelf body 2 to be stably positioned in the second position, by Figure 1As shown, it also includes a flange 4, which is fixed to the top of opposite sides of the frame 1 in the first direction, forming the opening of the enclosing cavity 101. The flange 4 can be a decorative element to prevent dust and moisture from entering the inner cavity of the frame 1, making it aesthetically pleasing; the flange 4 can also be a swinging element. When the shelf body 2 is in the first position, the flange 4 can swing to a position that locks the shelf body 2, preventing the shelf body 2 from being shaken out of the first position due to vibration; when the shelf body 2 is in the second position, the flange 4 can swing to the end away from the shelf body 2, facilitating the removal of the shelf body 2 and providing users with a good product experience.

[0034] Depend on Figure 1 and Figure 2 As shown, the sliding shelf also includes a push-pull rail 5, with the shelf body 2 fixedly connected to the push-pull rail 5, which faces the first direction. In this embodiment, the push-pull rail 5 can be selected as a display panel, fixedly installed at the end (front end) of the shelf body 2 facing the user, facilitating the user to push and pull the shelf body 2. It should be noted that the guardrail on the opposite side of the push-pull rail 5 is used to prevent goods on the shelf from falling from the rear end; this is a conventional technical means and will not be elaborated upon here.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
