DETAILED DESCRIPTION
[0024] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.
[0025] See also Figures 1 to 4 The present invention provides a rotating guardrail, comprising a rotating shaft 1, a first guardrail segment 2, and a second guardrail segment 3. One end of the first guardrail segment 2 and one end of the second guardrail segment 3 are both hinged to the rotating shaft 1. The rotating shaft 1 is located between the first guardrail segment 2 and the second guardrail segment 3, so that the first guardrail segment 2 and the second guardrail segment 3 can rotate about the rotating shaft 1 to adjust the installation position.
[0026] The rotary guardrail provided by the present invention cooperates with the first guardrail section 2 and the second guardrail section 3 hinged on the rotating shaft 1. In specific scenarios, such as road construction, temporary isolation, etc., the positions of the first guardrail section 2 and the second guardrail section 3 can be adjusted by rotating around the rotating shaft 1. When the first guardrail section 2 and the second guardrail section 3 are adjusted to a right angle state, one side of the road can be closed. When the first guardrail section 2 and the second guardrail section 3 are adjusted to an overlapping state, the guardrail can be opened to achieve interconnection between the roads on both sides. When the first guardrail section 2 and the second guardrail section 3 are adjusted to a straight state, the function of isolating the roads on both sides can be achieved. In this way, convenient adjustment of the guardrail position and flexible use of space are achieved, allowing the user to change the position or direction of the guardrail through a rotation operation without disassembling the guardrail.
[0027] The rotary guardrail of the present invention also includes a sleeve 4 and a support member 5. The sleeve 4 is rotatably mounted on the rotating shaft 1. The first guardrail segment 2 and the second guardrail segment 3 are hinged to the rotating shaft 1 through the sleeve 4. The end of the first guardrail segment 2 is fixedly connected to the corresponding outer circumference of the sleeve 4. The end of the second guardrail segment 3 is fixedly connected to the corresponding outer circumference of the sleeve 4. The support member 5 is fixed on the rotating shaft 1 to support the sleeve 4. Preferably, the support member 5 is fixed below the sleeve 4 at the bottom position. The support member 5 adopts a fixed disk. By introducing the sleeve 4 and rotatably mounting it on the rotating shaft 1, the present invention effectively disperses the stress and friction generated by the first guardrail segment 2 and the second guardrail segment 3 during the rotation process, reduces the direct wear of the rotating shaft 1, and thus significantly enhances the stability and durability of the entire guardrail structure. As an intermediate medium, the sleeve 4 not only protects the rotating shaft 1, but also ensures the smooth rotation action. The addition of support member 5 provides additional support for sleeve 4, ensuring that sleeve 4 remains stable when bearing the weight of the guardrail section and external forces. This design not only increases the load-bearing capacity of the guardrail, but also strengthens the stability of its overall structure, further enhancing the reliability of the guardrail in terms of safety protection.
[0028] The rotating guardrail of the present invention also includes a bearing 6, which is sleeved on the rotating shaft 1 between two adjacent sleeves 4 and between the sleeves 4 and the support member 5. By sleeved between two adjacent sleeves 4 and between the sleeves 4 and the support member 5 on the rotating shaft 1, the present invention significantly improves the smoothness of the guardrail's rotation. As a professional rotating support component, the ball or roller design inside the bearing 6 can effectively reduce frictional resistance during rotation, making it easier and smoother to adjust the position of the first and second guardrail sections, thereby extending the service life of the guardrail. The introduction of the bearing 6 not only improves the smoothness of rotation, but also enhances the stability and reliability of the entire guardrail structure. The bearing can withstand large radial and axial loads, effectively dissipating the stress generated during rotation, preventing deformation or damage to the rotating shaft 1, sleeves 4, and support member 5 due to uneven force over time, and ensuring the stable operation of the guardrail in complex usage environments. By adopting the bearing 6 as the rotating support component, the present invention effectively reduces the noise and vibration levels during rotation, improving the overall quality and user comfort of the product.
[0029] In this embodiment, the rotary guardrail of the present invention further includes a fixing column 7 fixed vertically to the installation plane, and the rotating shaft 1 is sleeved on the outer periphery of the fixing column 7 to fix the position of the rotating shaft 1.
[0030] This rotating guardrail also includes rollers 8 mounted at the bottom of the first and second guardrail sections 2, 3 to support movement of the sections on the mounting surface. To move the guardrails, users can simply push or pull them, without the need for additional tools or equipment. The rollers are designed with user experience in mind. Users can easily adjust the guardrail's position and layout based on their needs without the hassle of moving heavy guardrail sections, thereby improving work comfort and satisfaction.
[0031] See also Figure 5 The rotary guardrail of the present invention also includes a locking member 9 installed on the first guardrail segment 2 and the second guardrail segment 3 to fix the position of the first guardrail segment 2 and the second guardrail segment 3. The locking member 9 is installed on the first guardrail segment 2 and the second guardrail segment 3 and at one end away from the rotating shaft 1. The locking member 9 includes a locking rod 91 and an insertion tube 92. The insertion tube 92 is fixed on the first guardrail segment 2 and the second guardrail segment 3. The locking rod 91 can be movably inserted into the insertion tube 92 so that the bottom end of the locking rod 91 can be inserted into the limiting hole of the installation plane. The locking member 9 also includes a clamping member 93 fixed on the first guardrail segment 2 and the second guardrail segment 3 and located above the insertion tube 92. The bent portion at the top of the locking rod 91 can be movably clamped in the clamping member 93. By installing locking members 9 on the first and second guardrail sections 2 and 3, and designing a mechanism for the interaction between the locking rod 91, the insert 92, and the retaining member 93, the present invention securely secures the guardrails. When the bottom end of the locking rod 91 is inserted into the retaining hole on the mounting surface and, through the bent portion, is retained within the retaining member 93, the guardrail sections are stably locked in their predetermined positions, effectively preventing the guardrails from shifting or tipping over due to external forces, significantly improving their stability and safety.
[0032] See also Figure 4 In this embodiment, the first guardrail section 2 includes a fixed frame 21 and a plurality of railings 22 installed in the fixed frame 21. The shaft sleeve 4 is fixed to the fixed frame 21. Reflective marks 23 are fixed on the railings 22 at intervals.
[0033] The rotating guardrail provided by the present invention utilizes a first guardrail segment 2 and a second guardrail segment 3 hinged on a rotating shaft 1. In specific scenarios, such as road construction and temporary isolation, the positions of the first and second guardrail segments 2 and 3 can be adjusted by rotating about the rotating shaft 1. When the first and second guardrail segments 2 and 3 are adjusted to a right angle, one side of the road can be closed. When the first and second guardrail segments 2 and 3 are adjusted to overlap, the guardrail can be opened to allow access to the two sides of the road. When the first and second guardrail segments 2 and 3 are adjusted to a straight line, the two sides of the road can be isolated.
