Detailed Implementation

[0028] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] This utility model provides a foldable handrail, comprising: an upper upright post 1, a rotating rod 2, and a connecting assembly 3. The upper upright post 1 is fixed to a wall. The first end of the rotating rod 2 is hinged to the wall, and the second end of the rotating rod 2 is provided with the connecting assembly 3. The rotating rod 2 is detachably connected to the upper upright post through the connecting assembly 3. A support bar 21 is also provided on the rotating rod 2, and the first end of the support bar 21 is hinged to the rotating rod 2. The rotating rod 2 has a retracted state and an extended state. When the rotating rod 2 is in the retracted state, the second end of the rotating rod 2 is connected to the upper upright post 1 through the connecting assembly 3. When the rotating rod 2 is in the extended state, the rotating rod 2 is perpendicular to the wall, and the second end of the support bar 21 is fixed to the wall.

[0033] In the above solution, when the rotating rod 2 is in the retracted state, it is connected to the upper upright rod 1 fixed to the wall via the connecting component 3. At this time, the rotating rod 2 can serve as a handrail or hanging rod. When the rotating rod 2 is in the extended state, it can serve as a handrail for sitting or standing up. This invention, by installing a rotating rod 2 on the wall, utilizes the rotation of the rotating rod 2 to achieve the function of a handrail for hanging items or standing up, thus reducing space occupation and enriching the function of the handrail.

[0034] Furthermore, the connecting assembly 3 includes a sliding cylinder 31, a connecting rod 32, and an elastic element 33; a connecting hole 11 is provided on the end face of the upper upright rod 1 opposite to the rotating rod 2. The sliding cylinder 31 is slidably disposed at the second end of the rotating rod 2, the connecting rod 32 is disposed inside the sliding cylinder 31, and an elastic element 33 is disposed between the connecting rod 32 and the second end of the rotating rod 2. The elastic element 33 is used to apply elastic force to the connecting rod 32 so that the first end of the connecting rod 32 extends out of the sliding cylinder 31; the sliding cylinder 31 is used to drive the connecting rod 32 to move so that the connecting rod 32 extends into or slides out of the connecting hole 11.

[0035] In the above solution, the elastic force of the elastic element 33 is used to bring one end of the connecting rod 32 out of the sliding cylinder 31 and insert it into the connecting hole 11 of the upper upright 1, thereby connecting the rotating rod 2 with the upper upright 1 and completing the storage of the rotating rod 2. When the rotating rod 2 needs to be in the unfolded state, the user drives the sliding cylinder 31 to slide, causing the end of the connecting rod 32 to slide out of the connecting hole 11. After rotating the rotating rod 2 to a horizontal state, the second end of the support bar 21 is fixed to the wall, completing the state transition of the rotating rod 2. The user only needs to drive the sliding cylinder 31 to unlock the rotating rod 2 and the upper upright 1. In a preferred embodiment, the outer wall of the sliding cylinder 31 is provided with anti-slip texture to facilitate the user to drive the sliding cylinder 31 by hand. In addition, the elastic element 33 is preferably a spring or an elastic sleeve. The rotating rod 2 is provided with a strip groove 24 for accommodating the support bar 21. Storing the support bar 21 inside the rotating rod 2 greatly reduces the space occupied.

[0036] Furthermore, the connecting assembly 3 also includes a limiting slider 34, and a guide post 22 is provided at the second end of the rotating rod 2. The diameter of the guide post 22 is larger than the diameter of the rotating rod 2. A sliding cylinder 31 is sleeved on the guide post 22 and is used to slide along the guide post 22. The limiting slider 34 is slidably mounted on the rotating rod 2 and is fixedly connected to the sliding cylinder 31. The guide post 22 is used to limit the displacement of the limiting slider 34 on the rotating rod 2, so that the sliding cylinder 31 slides out of the guide post 22.

[0037] Furthermore, the rotating rod 2 has a guide hole 23 along its axial direction, and the sliding cylinder 31 is a hollow tubular structure with one end open. The other end of the sliding cylinder 31 has a through hole 35. One end of the connecting rod 32 is inserted into the guide hole 23, and the other end of the connecting rod 32 extends out of the sliding cylinder 31 through the through hole 35. The center line of the guide hole 23 and the center line of the through hole 35 are collinear. By placing both ends of the connecting rod 32 in the guide hole 23 and the through hole 35 respectively, the movement of the connecting rod 32 can be guided, and the stability of the connection between the connecting rod 32 and the upper upright 1 can be increased.

[0038] In a preferred embodiment, a baffle 36 is provided between the two ends of the connecting rod 32. One end of the elastic element 33 abuts against the end face of the guide post 22, and the other end of the elastic element 33 abuts against the baffle 36. In this embodiment, the baffle 36 is located inside the sliding cylinder 31, and the diameter of the baffle 36 is larger than the diameter of the reserved hole 35. Providing the baffle 36 on the connecting rod 32 can prevent the connecting rod 32 from sliding out of the sliding cylinder 31, and the baffle 36 can also be used to abut against the elastic element 33.

[0039] Finally, the handrail also includes a positioning block 4 for mounting on the wall. The positioning block 4 is provided with a positioning hole. When the rotating rod 2 is in the extended state, the second end of the support bar 21 is fixedly connected to the positioning block 4 through the positioning hole. Specifically, the second end of the support bar 21 is fixedly connected to the positioning block 4 through a fastener.

[0040] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of this utility model should be covered by the protection scope of this utility model.
