Detailed Implementation

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Example 1

[0026] Please refer to Figures 1 to 6 As shown, a folding shelf includes an upper base frame 1, with a railing 2 fixedly connected to the top edge of the upper base frame 1. Two shelf legs 10 are connected to both ends of the upper base frame 1 via rotating components. A folding assembly connects two adjacent shelf legs 10, and a lower shelf 22 is detachably connected between the two folding assemblies. The folding assembly includes two hinged folding pieces 11, with the ends of the two folding pieces 11 hinged to the two shelf legs 10 respectively.

[0027] Those skilled in the art will understand that this utility model features four shelves, each with two legs 10 at each end of the width of the upper base frame 1. The lower plate 22 is used to limit and fix the two legs 10 on each side, while simultaneously ensuring that the four legs 10 form a single unit, making the structure of the legs 10 more stable. When storing or transporting this shelf, the lower plate 22 is removed from the two folding components. Then, the two legs 10, which are initially positioned outwards, are rotated inwards through the folding components until they are nearly parallel to each other. Then, the two legs 10 on both sides are rotated through the rotating components to move them into the upper base frame 1, thus folding and storing the shelf. This significantly reduces the space occupied by the shelf, facilitating its transport or storage.

[0028] In addition, when the two brackets 10 located in the same rotating assembly rotate in opposite directions, they will cause the two folding pieces 11 to unfold. When the two folding pieces 11 unfold to form a straight line, the two brackets 10 unfold outward to their maximum value. At the same time, the brackets 10 will abut against the side plate of the elastic limiting piece 7. When it is necessary to rotate the two brackets 10 to close them, simply lift the hinge point of the two folding pieces 11 upward or push it downward, which will cause the two brackets 10 to rotate and close.

[0029] Example 2

[0030] Furthermore, an acrylic decorative panel 3 is provided on the top of the fence 2, and an upper frame 4 is fixedly connected to the top of the upper base frame 1. A matching cover plate 5 is fitted on the upper frame 4, and a decorative wooden strip 12 is also provided on the top of the upper base frame 1. The strip can be detachably installed on the top of the upper base frame 1 by countersunk hexagonal screws 13.

[0031] Those skilled in the art will understand that, in use, by fitting the cover plate 5 onto the upper shelf 4, items can be placed directly on the cover plate 5. When transporting this shelf, the cover plate 5 can be removed from the upper shelf 4, and then the acrylic decorative panel 3 can be placed on top of the upper shelf 4. The cover plate 5 can then be placed over the acrylic decorative panel 3 to protect it.

[0032] In addition, the acrylic decorative panel 3 has high light transmittance and can replace glass to create a transparent visual effect. When combined with lighting, it can enhance the spatial layering and light and shadow art effect. Moreover, the acrylic decorative panel 3 has strong impact resistance and forms blunt fragments after breaking, which is safer than glass. It also has excellent weather resistance, is UV resistant and does not easily yellow, making it suitable for long-term indoor and outdoor use. By setting up decorative wooden strips 12, a natural texture or artistic feel can be added, which helps to improve the aesthetics of the shelf. The detachable setting of the decorative wooden strips 12 makes it easy to remove the decorative wooden strips 12 and replace them with decorative wooden strips 12 with different textures, colors or shapes.

[0033] Example 3

[0034] Furthermore, fixing plates 15 are provided on both sides of the acrylic decorative panel 3. Several semi-circular head hexagonal screws 16 are inserted between the two fixing plates 15 and the acrylic decorative panel 3. The outer end of the semi-circular head hexagonal screws 16 is threaded with a press-fit nut 17. A slot 18 that matches the fence 2 is formed between the bottom of the acrylic decorative panel 3 and the two fixing plates 15. The acrylic decorative panel 3 is secured to the top of the fence 2 through the slot 18. Several round holes 14 are opened on the acrylic decorative panel 3. The top of the upper shelf 4 is also provided with insertion holes 20 that match each press-fit nut 17.

[0035] Those skilled in the art will understand that the acrylic decorative panel 3 in this utility model is detachable. When folding and storing this shelf, the acrylic decorative panel 3 can be removed from the fence 2 to further reduce the space ratio of the shelf. The several round holes 14 are provided for installing lamps.

[0036] In addition, when the acrylic decorative panel 3 is placed on top of the upper shelf 4 for storage, several pressure nuts 17 on the acrylic decorative panel 3 need to be inserted into the corresponding holes 20 to limit the acrylic decorative panel 3 and prevent it from sliding and falling off when the shelf is moved and folded, which would damage the acrylic decorative panel 3.

[0037] Example 4

[0038] Furthermore, the rotating assembly includes two elastic limiting plates 7 disposed at both ends of the upper base frame 1. The elastic limiting plates 7 are U-shaped, and both side plates of the elastic limiting plates 7 are rotatably connected to the upper base frame 1 via first bolt assemblies 6. Corresponding fixed inner plates 8 are disposed on the inner sides of both elastic limiting plates 7. The elastic limiting plates 7 and their corresponding fixed inner plates 8 are connected via two second bolt assemblies 9. Two frame legs 10 are disposed between the elastic limiting plates 7 and their corresponding fixed inner plates 8, and are rotatably connected to the two second bolt assemblies 9 respectively. The elastic limiting plates are elastic enough to abut against the side walls of the frame legs.

[0039] Those skilled in the art will understand that the two elastic limiting pieces 7 in this utility model are rotated at both ends of the upper base frame 1 by two first bolt assemblies 6, thereby driving the frame legs 10 to fold and unfold. The two frame legs 10 connected in a single elastic limiting piece 7 can be rotated to close or unfold by the second bolt assembly 9.

[0040] In addition, the elastic limiting piece 7 is U-shaped, so that the two side plates of the elastic limiting piece 7 can limit the two outwardly rotating bracket legs 10. When the bracket legs 10 rotate outward to a certain angle, they will abut against the side plates of the elastic limiting piece 7, and through cooperation with the folding assembly, limit the opening and closing angle of the two bracket legs 10. The elastic limiting piece is elastic and abuts against the side wall of the bracket leg.

[0041] Example 5

[0042] Furthermore, the first bolt assembly 6 includes a first hexagon socket screw 601 that is simultaneously inserted into the side plate of the elastic limiting plate 7 and the upper base frame 1. One end of the first hexagon socket screw 601 is threadedly connected to a first anti-loosening nut 602. A first plastic washer 603 is fitted on the first hexagon socket screw 601 between the side plate of the elastic limiting plate 7 and the upper base frame 1. A first flat washer 604 is also fitted on the first hexagon socket screw 601 between the side plate of the elastic limiting plate 7 and the first anti-loosening nut 602. The two side plates of the elastic limiting plate 7 are rotatably connected to the two first hexagon socket screws 601 respectively.

[0043] Those skilled in the art will understand that in this utility model, the side plate of the elastic limiting piece 7 is rotatably connected to the unthreaded position of the first internal hexagon screw 601, and the first plastic washer 603 is provided to isolate the side plate of the elastic limiting piece 7 from direct contact with the upper base frame 1, thereby reducing friction and wear.

[0044] Example 6

[0045] Furthermore, the second bolt assembly 9 includes a second hexagon socket screw 901 that is simultaneously inserted into the main body of the elastic limiting plate 7, the bracket 10, and the fixed inner plate 8. One end of the second hexagon socket screw 901 is threadedly connected to a second anti-loosening nut 902. A second plastic washer 903 is fitted on the second hexagon socket screw 901 between the main body of the elastic limiting plate 7 and the bracket 10. A second flat washer 904 is also fitted on the second hexagon socket screw 901 between the fixed inner plate 8 and the second anti-loosening nut 902. The bracket 10 is rotatably connected to the second hexagon socket screw 901.

[0046] Those skilled in the art will understand that in this utility model, the bracket 10 is rotatably connected to the unthreaded position of the second internal hexagon screw 901, and the second plastic washer 903 is provided to isolate the main board of the elastic limiting piece 7 from direct contact with the bracket 10, thereby reducing wear.

[0047] Example 7

[0048] Furthermore, both ends of the upper base frame 1 are fixedly connected with limiting rods 19 to limit the rotation angle of the elastic limiting plate 7, and both ends of the upper base frame 1 are also fixedly connected with connecting rods 24.

[0049] Those skilled in the art will understand that the limiting rod 19 in this utility model is used to assist in limiting the rotation angle of the elastic limiting plate 7, so that after the elastic limiting plates 7 on both sides rotate outward to a certain angle, the elastic limiting plates 7 will abut against the limiting rod 19, thereby playing a limiting role.

[0050] In addition, the connecting rod 24 is easy for people to grip, making it convenient for people to lift and move the upper base frame 1. At the same time, the connecting rod 24 can support the upper base frame 1, enhance the structural strength of the upper base frame 1, and make the structure of the upper base frame 1 more stable.

[0051] Example 8

[0052] Furthermore, each folding piece 11 has an integrally formed mounting plate 21 on its top, and a lower plate 22 is simultaneously attached to the top of each mounting plate 21. Each mounting plate 21 and the lower plate 22 is connected by a fixing screw 23.

[0053] Those skilled in the art will understand that, during installation, the lower shelf 22 of this utility model requires that the two folding pieces 11 on both sides be in a straight line, so as to ensure that each mounting plate 21 is on the same plane. This facilitates the stable mounting of the lower shelf 22 on the top of each mounting plate 21, and also facilitates the alignment of the screw holes of the lower shelf 22 with the screw holes on the mounting plate 21, so that the fixing screws 23 can be smoothly screwed into the screw holes. Furthermore, when the shelf is in use, items can also be placed on the top of the lower shelf 22, increasing the usable space.

[0054] The working principle and usage process of this device are as follows: When storing or transporting this shelf, the lower shelf 22 is removed from the two folding components. Then, the two shelf legs 10 are rotated inward and folded together by the folding components until they are nearly parallel to each other. Then, the two shelf legs 10 on both sides are rotated by the rotating components until they are inside the upper base frame 1. Then, the cover plate 5 is removed from the upper shelf 4, and the acrylic decorative panel 3 is removed from the railing 2 and placed on top of the upper shelf 4. When placing the acrylic decorative panel 3, several pressure nuts 17 on the acrylic decorative panel 3 need to be inserted into the corresponding insertion holes 20 to limit the acrylic decorative panel 3. Then, the cover plate 5 is placed on the acrylic decorative panel 3 to complete the folding and storage.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
