[0061] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0062] Example 1

[0063] As attached Figure 1 and appendix Figure 2As shown, this embodiment discloses a height adjustment device 1 for adjusting the height of a guardrail mechanism 3 on which the height adjustment device 1 is installed. It mainly includes a lifting mechanism 11, a moving mechanism 13, a fixing mechanism 12, and a holding mechanism 16. In use, the lifting mechanism 11 is first pulled towards its height direction; then, the lifting mechanism 11 moves synchronously with the moving mechanism 13 and the holding mechanism 16; during this process, the holding mechanism 16 gradually moves away from the first blocking part 121 of the fixing mechanism 12; after a period of time, the moving mechanism 13 is pushed towards the side away from the fixing mechanism 12, thus achieving height adjustment.

[0064] The specific structure of the height adjustment device 1 is as follows: it includes a lifting mechanism 11, on which a slot 111 is provided, and a through groove 112 is provided inside the lifting mechanism 11, and the slot 111 communicates with the through groove 112; a moving mechanism 13 is provided at the position of the slot 111; a fixing mechanism 12 is provided on one side of the lifting mechanism 11, and a first blocking part 121 is provided inside the fixing mechanism 12; a holding mechanism 16 is provided in the through groove 112 of the lifting mechanism 11, and the holding mechanism 16 is connected to the moving mechanism 13, and part of the structure of the holding mechanism 16 is adapted to the first blocking part 121 of the fixing mechanism 12.

[0065] Furthermore, the lifting mechanism 11 is equipped with an elastic element 17. In a specific application scenario, as shown in the attached figure... Figure 2 As shown, the elastic element 17 is horizontally arranged in the slot 111 of the lifting mechanism 11. The left end of the elastic element 17 is connected to the inner wall of the slot 111, and the right end of the elastic element 17 is connected to the inner wall of the moving mechanism 13. When the user moves the lifting mechanism 11 toward the first direction A1 and then pushes the moving mechanism 13 toward the second direction B1, the elastic element 17 will be compressed, thereby driving the holding mechanism 16 away from the fixed mechanism 12. This design can improve the convenience of operation to a certain extent.

[0066] In another specific application scenario, the elastic element 17 can be a spring, which has the advantages of being easy to install and having a low cost.

[0067] In a specific application scenario, the moving mechanism 13 mainly includes a sliding part 131, a first connecting part 133, and a placement groove 132. (See attached diagram) Figure 2 As shown, the sliding part 131 is located on the upper side of the lifting mechanism 11. The sliding part 131 is generally arc-shaped, which makes it convenient for the user to push the sliding part 131. A first connecting part 133 is provided on the lower side of the sliding part 131. The first connecting part 133 is located in the slot 111 of the lifting mechanism 11. A placement groove 132 is provided on the side of the first connecting part 133 facing the slot 111. The inner wall of the placement groove 132 is connected to the right end of the elastic member 17.

[0068] In a specific application scenario, the holding mechanism 16, located within the through slot 112 of the lifting mechanism 11, mainly includes a second connecting part 161 and a hook part 162. The upper end of the second connecting part 161 is connected to the upper end of the first connecting part 133; the lower end of the second connecting part 161 is connected to the left side of the top of the hook part 162. A locking block 1621 is provided at the lower right end of the hook part 162. This locking block 1621 is adapted to the first blocking part 121, and without external force, the locking block 1621 cannot leave the first blocking part 121. The hook part 162 has a through hole 1622, a design that reduces the weight of the holding mechanism 16. The second connecting part 161 and the hook part 162 can be integrally connected, a design that reduces manufacturing difficulty. (See attached...) Figure 2 As shown, the holding mechanism 16 is L-shaped and can occupy the areas of the lifting mechanism 11 and the fixing mechanism 12 at the same time. Furthermore, the upper right corner of the hook 162 is chamfered, which facilitates the hook 162 to leave the fixing mechanism 12 under the action of the lifting mechanism 11.

[0069] This embodiment also considers a situation, and the specific solution is as follows: (see attached) Figure 2 As shown, a receiving portion 113 is provided in the through groove 112 of the lifting mechanism 11 and near the first blocking portion 121. The receiving portion 113 can accommodate part of the structure of the hook portion 162. When the hook portion 162 leaves the fixing mechanism 12, the right side of the hook portion 162 can be in the receiving portion 113 to prevent the hook portion 162 from being suspended inside the lifting mechanism 11. If the receiving portion 113 is not provided and the hook portion 162 is in a suspended state, the moving mechanism 13 will have to bear all the weight generated by the clamping mechanism 16. Therefore, the receiving portion 113 in the lifting mechanism 11 greatly reduces the workload of the moving mechanism 13.

[0070] In another specific application scenario, the card-holding mechanism 16 can be made of iron sheet, which has the advantage of low cost.

[0071] Example 2

[0072] As attached Figure 1 As shown, this embodiment discloses a height adjustment device 1 to enhance the working performance of the aforementioned embodiment 1. In addition to the components in the aforementioned embodiment 1, it also includes an auxiliary lifting mechanism 15 and a fixed column 14. The auxiliary lifting mechanism 15 allows the lifting mechanism 11 to move along a preset path; the fixed column 14 can enhance the overall structural stability of the height adjustment device 1.

[0073] In a specific application scenario, the auxiliary lifting mechanism 15 mainly includes a slide 151 and a stop block 152. The slide 151 is generally vertical and slidably disposed at the bottom end of the lifting mechanism 11. Several second blocking parts 1511 are provided on the front side of the slide 151. The function of the second blocking parts 1511 is the same as that of the aforementioned first blocking parts 121. Therefore, in this embodiment, different heights can be adjusted under the action of the second blocking parts 1511. There are baffles (not marked in the figure) on both the left and right sides of the slide 151. The lifting mechanism 11 can move up and down along the length of the baffles. Several holes (not marked in the figure) are provided on the front side of the slide 151. This design can reduce the overall weight of the slide 151. In addition, a stop block 152 is provided at the lower end of the slide 151. This design can prevent the lifting mechanism 11 from sliding out of the slide 151.

[0074] In a specific application scenario, a fixing post 14 is provided on the rear side of the slide 151, and the top of the fixing post 14 passes through the interior of the fixing mechanism 12. This design can enhance the stability of the overall structure of the height adjustment device 1.

[0075] In another specific application scenario, the fixed column 14 can be a column tube with a hollow structure in the middle, which can reduce the overall weight of the height adjustment device 1 to a certain extent.

[0076] Example 3

[0077] As attached Figure 3 and appendix Figure 4 As shown, this embodiment discloses a crib designed to improve infant safety. In addition to the components described in Embodiment 2, it includes a bed board 4, a headboard 2, a flexible guardrail 6, and a guardrail mechanism 3. The bed board 4 can support the infant's weight; the headboard 2 and the flexible guardrail 6 prevent the infant from leaving the crib on their own, while the flexible guardrail 6 reduces the possibility of the infant being injured by bumps; the guardrail mechanism 3, equipped with a height adjustment device 1, prevents the infant from adjusting the height of the crib themselves, thereby improving the infant's safety.

[0078] In a specific application scenario, as shown in the appendix Figure 3As shown, the crib has a bed board 4 on its lower side, headboards 2 on both the left and right ends of the bed board 4, and elastic guardrails 6 on both the front and back sides of the bed board 4. Guardrail mechanisms 3 are provided on the upper sides of both the headboards 2 and the elastic guardrails 6. The guardrail mechanisms 3 are equipped with the aforementioned height adjustment device 1, which is located at the junction of the left and right headboards 2 and the front elastic guardrail 6. Alternatively, the height adjustment device 1 can be located at the junction of the left and right headboards 2 and the rear elastic guardrail 6. Likewise, the height adjustment device 1 can be installed at the junctions of both the headboards 2 and the elastic guardrail 6. Users can choose the appropriate solution according to their needs.

[0079] In another specific application scenario, the bed board 4 can be an elastic bed board 4, which can improve the baby's comfort; the headboard 2 can be an elastic headboard 2, which can reduce the possibility of the baby being injured by bumps.

[0080] Furthermore, the guardrail mechanism 3 mainly includes the guardrail 31, the handrail 32, and the guardrail sleeve 33. In a specific application scenario, as shown in the attached diagram... Figure 4 As shown, the guardrail mechanism 3 is located on the upper side of the headboard 2 and the elastic guardrail panel 6. The aforementioned height adjustment device 1 is provided at both ends of the front guardrail 31. Under the action of the height adjustment device 1, the height of the guardrail 31 can be changed. The guardrail 31 is provided with a handrail 32, which is generally located in the middle of the guardrail 31. When the infant places their hand on one side of the guardrail 31, the infant generally will not slide directly from one side to the other side of the guardrail 31 because the handrail 32 can provide a certain degree of cushioning. This design can reduce the degree of injury to the infant. (See attached...) Figure 3 As shown, a guardrail cover 33 is provided on the outside of the guardrail 31. This design can prevent the baby from directly contacting the guardrail 31.

[0081] Furthermore, as shown in the appendix Figure 4As shown, the crib is equipped with a support mechanism 5; the support mechanism 5 mainly includes a support plate 51, leg members 52, and support members 53. The support plate 51 in the support mechanism 5 is located at the bottom end of the bed board 4. The support plate 51 is equipped with leg members 52, and the ends of the leg members 52 extending in all directions are equipped with support members 53. The tops of the two front support members 53 are connected to the fixing posts 14 of the height adjustment device 1, and the tops of the two rear support members 53 are connected to the bottom ends of the fixing devices (not marked in the figure) of the guardrail 31. If the user needs the height of the crib to be adjustable on both the front and rear sides, the fixing devices of the guardrail 31 can be replaced with the aforementioned height adjustment device 1. In this case, the tops of the support members 53 are all connected to the fixing posts 14 of the height adjustment device 1. In use, first lift the guardrail 31 and lifting mechanism 11 on the right side of the front, and move the holding mechanism 16 away from the first blocking part 121 in the fixing mechanism 12; then, push the moving mechanism 13; next, move the lifting mechanism 11 downward; when the position of the lifting mechanism 11 meets your needs, release the right lifting mechanism 11; then, operate the lifting mechanism 11 on the left side of the front in the same way to make the left and right sides the same height, thereby realizing the height adjustment of this embodiment, and also improving the safety of the baby.
