[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "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 utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] The wall-mounted shelf with a folding and extending structure disclosed in this utility model is mainly used in scenarios where the structure is relatively fixed after the shelf panels are installed, making it inconvenient to adjust the spacing between the shelves according to the height of the items, resulting in poor applicability.

[0020] Reference Figure 1 and Figure 2A wall-mounted shelf with a folding and extending structure includes a first shelf 1, a second shelf 2 rotatably connected to the right side of the first shelf 1, a receiving plate 3 slidably connected to the inner sides of both the first shelf 1 and the second shelf 2, a limiting groove 4 opened at the upper end of the second shelf 2, a limiting post 5 slidably connected inside the limiting groove 4, a fixing block 6 fixedly installed on the side of the limiting post 5 away from the central axis, a locking block 7 rotatably connected to the front end of the fixing block 6, a locking groove 8 opened on the upper side of the front and rear ends of the second shelf 2 on the right side of the locking block 7, a sliding groove 9 opened in the middle of the front and rear ends of both the first shelf 1 and the second shelf 2, a locking nut 10 threadedly connected to the left and right sides of the front and rear ends of the receiving plate 3, a limiting block 11 rotatably connected to the side of the locking nut 10 near the central axis, a first rubber pad 12 adhered to the side of the limiting block 11 near the central axis, and a fixing groove 13 opened at the upper end of the first shelf 1.

[0021] In this embodiment: When using the wall-mounted shelf, if it is necessary to adjust the spacing between the support plates 3, loosen the locking nut 10, causing the limiting block 11 to slide outward, thereby causing the first rubber pad 12 to disengage from the sliding groove 9, thus locking the support plate 3. Slide the support plate 3 on the first shelf 1. After sliding the support plate 3 to the appropriate position, tighten the locking nut 10, causing the limiting block 11 to slide into the sliding groove 9, so that the first rubber pad 12 on the limiting block 11 is in contact with the sliding groove 9, thereby locking the support plate 3. This facilitates the adjustment of the spacing between the support plates 3 according to the height of the stored items, improving the applicability of the wall-mounted shelf. Simultaneously, when multiple types of items need to be placed, rotate the second shelf 2 to... The upper end of the first shelf 1 is brought into contact with the upper end of the second shelf 2. Then, the locking block 7 is pulled to move the fixing block 6 down, so that the limiting post 5 slides out of the limiting groove 4 and into the fixing groove 13. Then, the locking block 7 is rotated to lock into the locking groove 8, thereby locking the limiting post 5. If multiple items need to be placed and stored, the second shelf 2 can be rotated to the upper end of the first shelf 1 to unfold the wall-mounted shelf, thereby increasing the number of supporting plates 3 and increasing the variety of items that can be stored on the wall-mounted shelf. When the first shelf 1 and the second shelf 2 are in the folded state, the supporting plates 3 of the first shelf 1 and the supporting plates 3 of the second shelf 2 are adjusted to the same plane to increase the number of items that can be placed on each supporting plate 3.

[0022] Reference Figure 1 , Figure 3 and Figure 4The first shelf 1 and the second shelf 2 have movable grooves 14 at their lower ends. An extension rod 15 is slidably connected inside the movable groove 14. A guide rod 16 is fixedly installed in the middle of the movable groove 14. Stabilizing blocks 17 are fixedly installed at the front and rear ends of the extension rod 15. The first shelf 1 and the second shelf 2 have empty grooves 18 on the side away from the central axis. A threaded column 19 is fixedly installed on the side of the extension rod 15 away from the central axis. A fixing nut 20 is threadedly connected to the outside of the threaded column 19. A second rubber pad 21 is glued to the side of the fixing nut 20 near the central axis. A foot 22 is fixedly installed at the bottom end of the extension rod 15.

[0023] In this embodiment: When using a wall-mounted shelf, if it is necessary to extend the shelf, loosen the fixing nut 20 to release the second rubber pad 21 from its contact with the first shelf 1. Then, slide the threaded post 19 in the slot 18, thereby driving the extension rod 15 to slide in the movable slot 14. The guide rod 16 improves the stability of the extension rod 15 during sliding and also improves the structural strength of the extension rod 15 after extension. Slide the extension rod 15 out of the movable slot 14 to a suitable height, ensuring that the pad 22 remains in contact with the ground. Then, tighten the fixing nut 20 to make the second rubber pad 21 contact the first shelf 1. The shelf 1 is attached, thereby locking the extension rod 15 and enabling the extension of the wall-mounted shelf. After the wall-mounted shelf is extended, the support plate 3 can be slid onto the extension rod 15. The stabilizing block 17 on the extension rod 15 will fit against the inner wall of the support plate 3 to ensure the stability of the support plate 3. After the wall-mounted shelf is extended, the spacing of the support plates 3 can be further adjusted to facilitate the extension and adjustment of the wall-mounted shelf according to the height of the placed items. At the same time, when the ground is uneven, the height of each extension rod 15 can be adjusted individually to improve the flatness of the wall-mounted shelf.

[0024] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
