Description

Technical Field

[0001] The utility model relates to the technical field of child bed structures, in particular to a folding structure for a baby bed armrest. Background Art

[0002] Cribs are designed for infants and young children. They should not only provide a safe and comfortable sleeping environment, but also take into account the convenience of parents. When choosing a crib, parents need to take safety as the primary consideration. The spacing between the bed rails should be moderate to prevent the baby's head or body parts from being stuck; the structure of the bed must be stable to support the child's lively nature; and the material of the bed should be non-toxic, harmless, and environmentally friendly to ensure that the baby's health is not affected. In addition to safety, practicality is also an important consideration when choosing a crib. The ideal crib should be equipped with an adjustable bed base to adapt to the different stages of the child's growth. segment, thereby extending the service life. At the same time, the guardrails on the side of the bed should be easily disassembled and folded so that parents can pick up or put down their children. For example, the prior art represented by the comparative document "A bed armrest synchronous linkage structure" (application number 202222708685.8) realizes synchronous linkage folding or opening through sliding connection of the lower tubes of the armrests on both sides through linkage parts and joint connectors. The operation is simple and convenient when opening and folding, and the efficiency is high. It also improves the stability of the overall structure, thereby effectively solving the problems of the prior art. However, its structure still needs to be improved, as follows:

[0003] In this solution, the folding shell is made of iron, and then the iron sheet shell is hollowed out to form a slide. When sliding, the slide is folded on the thin iron sheet through a screw on the handrail rod. This method causes: 1. If the installation operation is improper when the product leaves the factory, the armrest cannot be folded; 2. The slide slides through the shell, and the contact area between the handrail rod screw and the slide of the shell is small, and the force area is small, resulting in overall instability and easy deformation. Sometimes the iron sheet is prone to rust, causing sliding jams. Therefore, a baby crib armrest folding structure is needed to improve the above problems. Utility Model Content

[0020] For examples, see Figure 1-4 , the utility model provides a technical solution:

[0021] A folding structure for an armrest of a baby crib comprises a top corner shell 1, an upper armrest rod 2 is arranged on the inner wall of the top corner shell 1, a sliding groove 3 is opened on the outer wall of the upper armrest rod 2, a fixing rivet 4 is slidably connected to the inner wall of the sliding groove 3, a folding box 5 is arranged on the outer wall of the upper armrest rod 2, the fixing rivet 4 is connected to the inner wall of the folding box 5, a lower armrest rod 7 is installed on the inner wall of the folding box 5 via a connecting rivet 6, one end of the lower armrest rod 7 is connected to the top corner shell 1, a slider 9 is installed on the inner wall of the folding box 5 via a positioning rivet 8, a fixing piece 10 is plugged and installed at the port of the upper armrest rod 2, a mounting hole 11 is opened on the outer wall of the fixing piece 10, a spring 12 is arranged on the inner wall of the mounting hole 11, and one end of the spring 12 is connected to the fixing rivet 4.

[0022] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The upper handrail rod 2 is respectively connected to the outer wall of the top corner shell 1 and the folding box 5 by rotation through the fixing rivet 4, and the lower handrail rod 7 is respectively connected to the outer wall of the top corner shell 1 and the folding box 5 by rotation through the positioning rivet 8. The sliding groove 3 is located on one side of the mounting hole 11. The cross section of the slider 9 is a triangular structure. The upper handrail rod 2 is provided with two groups and is respectively located on the inner wall of the folding box 5. The lower handrail rod 7 is provided with two groups and is respectively located on the inner wall of the folding box 5. The connecting rivets 6 are provided with multiple groups and are respectively located on the inner wall of the folding box 5. The fixing piece 10 is located on one side of the slider 9. The fixing piece 10 is provided with two groups and is respectively located on the opposite inclined surfaces of the slider 9. The spring 12 plays a role in fixing the fixing piece 10.

[0023] Furthermore, the slider 9 is made of plastic, which is rust-proof and smooth to use, and has better practicality. The fixing part 10 is inserted into the upper handrail rod 2 and fixed with screws. The spring 12 is inserted into the middle inner hole of the fixing part 10, that is, the mounting hole 11, so that the spring 12 can better push the fixing part 10 to prevent it from falling off, and it is stable and firm.

[0024] The working process of the utility model: when the folding structure of the baby crib armrest designed by the present invention is working, a sliding groove 3 is opened on the outer wall of the upper armrest rod 2, and a fixing rivet 4 is slidably connected on the inner wall of the sliding groove 3. A folding box 5 is arranged on the outer wall of the upper armrest rod 2, and the inner wall of the folding box 5 is connected with the fixing rivet 4. Under the action of the fixing rivet 4, it is only necessary to rotate the upper armrest rod 2 so that the upper armrest rod 2 rotates on the fixing rivet 4, and the upper armrest rod 2 drives the fixing part 10 to slide on the surface of the slider 9. When in the unfolded state, the fixing part 10 is at the upper end of the slider 9. When folded, the curvature of the fixing part 10 matches the slope of the slider 9, so that it slides better, thereby making the device fold. The folding box 5 is folded and unfolded, and the upper handrail rod 2 drives the fixing part 10 to move. Since the slider 9 is fixed in the folding box 5, the middle of the folding box 5 remains in a solid state. The slider 9 is made of plastic, does not rust and is smooth to use. The fixing part 10 is built with a spring 12. When the upper handrail rod 2 is unfolded and used, the spring 12 can better push the fixing part 10 so that it does not fall off, and it is stable and firm, which is beneficial to solve the problem that the handrail cannot be folded if the installation operation is improper when the product leaves the factory; the slide slides through the shell, the contact surface of the slide of the handrail rod screw and the shell is small, and the force area is small, resulting in overall instability and easy deformation. Sometimes the iron sheet is easy to rust, causing the sliding jam problem.
