[0038] The following combines the accompanying drawings and embodiments to further describe in detail the specific implementation mode of the present utility model. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0039] Embodiment 1:

[0040] Combine Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, a bending positioning structure for a bed guardrail includes a support mechanism 1 and a surrounding mechanism 2. The surrounding mechanism 2 includes at least two upright columns 3 arranged side by side. A crossbar 4 is connected between the two upright columns 3. Wing guards 5 are installed on the outer sides of the two upright columns 3. A connecting mechanism 6 is arranged between the wing guards 5 and the upright columns 3. The connecting mechanism 6 includes a fixing member 61 installed at the top of the upright column 3. A rotating member 62 installed on the wing guard 5 is connected to the fixing member 61. A positioning pin 63 is arranged between the fixing member 61 and the rotating member 62. A spring member 631 is arranged inside the positioning pin 63. By pressing the positioning pin 63, the connecting mechanism 6 can be unlocked or fixed so that the wing guard 5 can be bent and positioned with the upright column 3. Specifically, a bending positioning structure for a bed guardrail provides a safe, stable and easy-to-operate protection solution for a children's bed. This structure mainly includes two core parts: a support mechanism 1 and a surrounding mechanism 2. The support mechanism 1 serves as the foundation of the entire bed guardrail. The support mechanism 1 is usually made of strong and durable metal materials such as stainless steel or high-strength alloys to ensure its stability and load-bearing capacity. The surrounding mechanism 2 includes at least two upright columns 3 arranged side by side. These upright columns 3 not only require sufficient strength to resist the pushing of children but also need to have good surface treatment such as anti-slip treatment or rounded corner design to prevent scratches. A crossbar 4 is connected between the two upright columns 3. The crossbar 4 not only enhances the overall structural stability but also effectively prevents children from passing through the gap. In addition, in order to further improve the protection range, wing guards 5 are installed on the outer sides of the two upright columns 3. These wing guards 5 can extend outward from the bed to form a wider protection barrier. The connecting mechanism 6 enables the wing guards 5 to be bent and positioned as needed to adapt to different bed types or space layouts. The connecting mechanism 6 includes fixing members 61 installed at the top of the upright columns 3. These fixing members 61 usually adopt threaded holes or snap-fasteners for easy installation and disassembly. The corresponding rotating member 62 installed on the wing guard 5 can rotate around the fixing member 61 within a certain range, thereby realizing the folding and unfolding of the wing guard 5. In order to ensure the safety and stability of the connection, a positioning pin 63 is arranged between the fixing member 61 and the rotating member 62. A spring member 631 is embedded inside the positioning pin 63, allowing users to unlock or fix the connecting mechanism 6 through a simple pressing action without complex tool operations, greatly improving the convenience of use. When the positioning pin 63 is pressed, the spring member 631 is compressed, allowing the rotating member 62 to rotate relative to the fixing member 61; after releasing the pressure, the spring member 631 returns to its original state, pushing the positioning pin 63 to snap back into the predetermined position, thereby firmly locking the position of the wing guard 5. This bending positioning structure for a bed guardrail not only provides efficient safety protection through the support mechanism, the surrounding mechanism 2 and the connecting mechanism 6 but also takes into account the flexibility and convenience of use, and is an indispensable safety device in modern family children's rooms.

[0041] Combined with Figure 1 、 Figure 5 、 Figure 6 andFigure 7 As shown, a connecting portion 611 is provided on the fixing member 61, an installation groove 612 is formed in the connecting portion 611, a connecting block 621 matching the installation groove 612 is provided on the rotating member 62, the connecting block 621 is embedded in the installation groove 612 and is coaxially rotatably connected to the connecting portion 611, and the positioning pin 63 is installed on the rotation axis of the connecting block 621 and the connecting portion 611. In combination with Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, one end of the spring member 631 abuts against the inner top of the positioning pin 63, and the other end of the spring member 631 abuts against the lower end A surface of the installation groove 612. In combination with Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, mounting holes 632 are provided on the rotation axes of both the connecting portion 611 and the connecting block 621, a sliding groove 633 is formed inside the mounting hole 632, the positioning pin 63 is installed inside the mounting hole 632, and a sliding block 634 matching the sliding groove 633 is provided on the outer wall of the positioning pin 63. In combination with Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, a number of positioning grooves 613 are provided on the inner wall of the mounting hole 632 around the connecting portion 611. A positioning block 635 matching the positioning groove 613 is provided on the positioning pin 63. The positioning pin 63 can be slidably engaged with the positioning groove 613 through the positioning block 635 to enable the wing stop 5 to be bent and positioned with the column 3. Specifically, on the main structure of the fixing member 61, a connecting portion 611 is provided, which is a key part for the rotating member 62 to be connected thereto and allow coaxial rotation. An installation groove 612 is formed on the connecting portion 611, and the shape and size of the installation groove 612 are precisely calculated to ensure a perfect match with the connecting block 621 on the rotating member 62. The connecting block 621, as a part of the rotating member 62, has a shape that closely fits the installation groove 612. When the connecting block 621 is inserted into the installation groove 612, the two can form a stable connecting structure capable of coaxial rotation. To further enhance the stability and durability of the connection, the positioning pin 63 is installed on the rotation axis of the connecting block 621 and the connecting portion 611. This not only ensures the accuracy and smoothness of the rotation action but also provides the necessary structural support for the subsequent bending positioning. The spring member 631 plays a crucial role in the positioning pin 63. One end thereof is in close contact with the inner top of the positioning pin 63, and the other end elastically contacts the lower end A surface of the installation groove 612. This enables the positioning pin 63 to have a certain elastic displacement when subjected to an external force, thereby realizing the unlocking or fixing function. The selection and debugging of the spring member 631 have undergone strict tests and verifications to ensure that it can provide stable elastic force and a long service life. Mounting holes 632 are provided on the rotation axes of both the connecting portion 611 and the connecting block 621. These mounting holes 632 not only provide an installation space for the positioning pin 63 but also have built-in sliding grooves 633. The design of the sliding grooves 633 enables the positioning pin 63 to slide freely inside the mounting hole 632 while ensuring the stability and accuracy of the sliding. Sliding blocks 634 matching the sliding grooves 633 are provided on the outer wall of the positioning pin 63. The movement of these sliding blocks 634 in the sliding grooves 633 ensures that the positioning pin 63 can slide along a predetermined trajectory. To achieve the bending positioning function between the wing stop 5 and the column 3, a number of positioning grooves 613 are also provided on the inner wall of the mounting hole 632 of the connecting portion 611. The shape and size of these positioning grooves 613 are precisely designed to ensure a perfect match with the positioning blocks 635 on the positioning pin 63. When the positioning pin 63 moves to different positions under the combined action of the sliding groove 633 and the spring member 631, the positioning block 635 will be inserted into different positioning grooves 613 accordingly, thereby realizing the stable positioning of the wing stop 5 and the column 3 at different angles. The design and mutual cooperation of components such as the fixing member 61, the rotating member 62, the positioning pin 63, and the spring member 631 together constitute the complex and delicate connecting mechanism 6.It not only realizes the flexible connection and bending positioning function between the wing guard 5 and the column 3, but also ensures the stability and durability of the connection, providing a strong guarantee for the safety and practicality of the bed guardrail.

[0042] Combined with Figure 1 , Figure 5 , Figure 6 and Figure 7 shown, when the wing guard 5 and the column 3 are bent, press the positioning pin 63 to make the positioning block 635 disengage from the positioning groove 613 to release the fixed state, rotate the wing guard 5 to adjust the angle between the wing guard 5 and the column 3. After the adjustment is completed, just release the positioning pin 63, and through the elastic force of the spring member 631, the positioning pin 63 is engaged with the positioning groove 613 to re-fix the angle between the wing guard 5 and the column 3. Specifically, when the wing guard 5 and the column 3 are bent and adjusted, the entire connecting mechanism 6 demonstrates its delicate design and high flexibility. When it is necessary to adjust the angle between the wing guard 5 and the column 3, the user first presses the positioning pin 63. This action overcomes the elastic force of the spring member 631, causing the positioning pin 63 to move along its axial direction. As the positioning pin 63 moves, the positioning block 635 thereon will gradually disengage from the current positioning groove 613, thus releasing the fixed state between the wing guard 5 and the column 3. Once the positioning block 635 disengages from the positioning groove 613, the wing guard 5 can rotate relative to the column 3 under the support of the connecting mechanism 6. The user only needs to release the previously pressed positioning pin 63. At this time, the spring member 631 will quickly restore its elastic force, pushing the positioning pin 63 to move in the opposite direction. As the positioning pin 63 moves, the positioning block 635 thereon will gradually approach and finally snap into the next suitable positioning groove 613. When the positioning block 635 successfully snaps into the positioning groove 613, the angle between the wing guard 5 and the column 3 is re-fixed. At this time, the connecting mechanism 6 is again in a stable state, and the wing guard 5 can firmly maintain the required rotation angle, providing safe and reliable protection for children. The design of the connecting mechanism 6 allows the wing guard 5 to be flexibly adjusted between multiple angles, so as to adapt to the needs of different bed types and space layouts. Specifically, in this embodiment, the positioning groove 613 is provided with two groups that are perpendicular to each other, and the included angle between the wing guard 5 and the crossbar 4 can be selected as 180°, or 90°, or 0°, that is, the wing guard 5 can be fully unfolded, or fully folded, or folded to 90°; or the positioning groove 613 is provided with three groups, and the included angle between the wing guard 5 and the crossbar 4 can be selected as 180° (as shown in Figure 3 ), or 135° (as shown in Figure 2 ), or 90° (as shown in Figure 1 ), or 0° (as shown in Figure 4 ).

[0043] Through the cooperation of the positioning pin 63 and the positioning groove 613, as well as the elastic force of the spring member 631, the connecting mechanism 6 can ensure that the wing guard 5 maintains a stable fixed state after the adjustment is completed. When the wing guard 5 is bent and adjusted with the column 3, the connecting mechanism 6 provides users with a convenient, stable and safe operation experience through its delicate design and flexible adjustment method.

[0044] Combined Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the support mechanism 1 includes a support frame 7 provided at the bottom of the column 3, and a connecting member 8 is provided at the connection between the support frame 7 and the column 3. Specifically, the support mechanism 1 not only concerns the stability of the entire guardrail, but also directly affects the installation convenience and use safety of the guardrail. The support mechanism 1 is the cornerstone of the bed guardrail, responsible for firmly installing the guardrail on the bed frame to prevent children from falling. This mechanism is usually made of high-strength and corrosion-resistant materials such as stainless steel or alloy steel to ensure its reliability and durability for long-term use. The support frame 7 is the core component in the support mechanism 1, directly contacting the bed frame and providing the necessary supporting force. The shape and size of the support frame 7 are usually customized according to the structure and size of the bed frame to ensure the best fit and stability. It may include horizontal support arms and vertical support legs. The horizontal support arms are used to contact the edge or bottom of the bed frame, while the vertical support legs are connected to the column 3. The design of the support frame 7 takes into account various factors, including load-bearing capacity, stability, installation convenience and aesthetics. To enhance the load-bearing capacity and stability, the support frame 7 may adopt designs such as reinforcing ribs or triangular structures. At the same time, for easy installation and disassembly, the connection part of the support frame 7 may use bolts, nuts, buckles or quick-release devices, etc. The connecting member 8 is the bridge between the support frame 7 and the column 3, responsible for firmly connecting the two together. The design of the connecting member 8 needs to consider the materials, shapes and sizes of the column 3 and the support frame 7 to ensure the best fit and connection strength. The connecting member 8 may adopt various forms, such as bolt connection, welding connection, snap connection or hinge connection, etc. Among them, bolt connection is a common and reliable method, allowing disassembly and reinstallation when needed. Welding connection is more solid, but once completed, it cannot be easily disassembled. Snap connection and hinge connection provide higher flexibility, allowing the column 3 to rotate or fold to a certain extent relative to the support frame 7.

[0045] Combined Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, both the connecting mechanism 6 and the connecting piece 8 are made of plastic materials. Specifically, the connecting mechanism 6 and the connecting piece 8 are key components in the bending and positioning structure of the bed guardrail, and the selection of their materials has an important impact on the performance, safety, and durability of the entire guardrail. The connecting mechanism 6 is responsible for the flexible rotation and stable positioning between the wing guard 5 and the column 3. Therefore, its material needs to have sufficient strength, toughness, and wear resistance. Plastic materials, especially engineering plastics such as nylon PA, polypropylene PP, polycarbonate PC, etc., have become ideal choices for the connecting mechanism 6 due to their light weight, corrosion resistance, easy processing, and high cost-effectiveness. The connecting piece 8 is responsible for connecting the support frame 7 and the column 3. Therefore, its material needs to have high strength, impact resistance, and corrosion resistance. Similarly, engineering plastics have become ideal choices for the connecting piece 8 due to their excellent comprehensive performance. When selecting plastic materials, their environmental friendliness also needs to be considered. Modern engineering plastics usually have good recyclability and biodegradability, which can reduce environmental pollution. Therefore, when designing and manufacturing the connecting mechanism 6 and the connecting piece 8, environmentally friendly plastic materials should be given priority to meet the requirements of sustainable development. The connecting mechanism 6 and the connecting piece 8 are made of plastic materials, not only having the advantages of high strength, toughness, wear resistance, and corrosion resistance, but also achieving the goals of lightweight, easy processing, and high cost-effectiveness. At the same time, the selection of environmentally friendly plastic materials also helps to reduce the negative impact on the environment.

[0048] The above are only the preferred embodiments of the present invention.
