[0002] The main reason for needing guardrails at metal railing corners is to prevent collisions and improve overall safety. Because of their high rigidity, the corners of metal railings can easily cause injury to the waist or head when cleaning or when children are playing, posing a danger. Installing guardrails can effectively reduce this risk and improve environmental safety.

[0003] Chinese Patent 202122405103.4 discloses an anti-collision strip, including a base, a main body cover disposed on the base, and a shock-absorbing structure for buffering and shock absorption. Multiple hollow bodies are fixed to the inner wall of the main body cover and are arranged along the axial direction of the main body cover. The hollow bodies are filled with filling gas. The base is provided with a slot for easy installation. The anti-collision strip effectively absorbs external impacts through tensile deformation, ensuring the anti-collision effect.

[0004] Existing corner protection structures typically use adhesive to attach silicone or foam anti-collision strips to corners. However, after prolonged use, the surface of the anti-collision strips is prone to damage or aging and discoloration, affecting aesthetics. Since the strips are fixed to the corners with adhesive, they are difficult to remove. Even if they are forcibly torn off, glue residue is easily left on the metal railing, which is difficult to clean. Furthermore, with prolonged use, the glue at the ends or corners is prone to aging and failure when exposed to rainwater, which can cause the ends or corners of the protective structure to not adhere firmly and to curl upwards, potentially causing scratches to the clothing of passersby.

[0005] To address the aforementioned issues, a metal railing corner protection structure is proposed. Utility Model Content

A first connecting piece 104 is fixedly connected to the outer wall of the tightening strap 103, and a concealed buckle 105 is fixedly connected to the bottom end of the first connecting piece 104. A concealed buckle female 106 is engaged with the side of the concealed buckle 105.

[0027] Please see Figure 1 , Figure 3 and Figure 5 The present invention relates to a metal railing corner protection structure, wherein the inner diameter of the tightening end 101 is consistent with the inner diameter of the silicone protective cylinder 201, and the outer diameter of the tightening end 101 gradually decreases from the end connected to the silicone protective cylinder 201 to the end connected to the tightening band 103. The number of port tightening components 1 is consistent with the number of protective cylinder components 2, and the port tightening components 1 and the protective cylinder components 2 correspond one-to-one.

[0028] When the protective cylinder assembly 2 and the corner protection block 3 are fastened to the corner of the metal railing, the tightening end 101 and the tightening strap 103 are also fitted onto the metal railing along with the silicone protective cylinder 201. At this time, simply tighten the first connecting piece 104 and press the hidden buckle 105 on the inner wall of the bottom end of the first connecting piece 104 onto the hidden buckle 106. This will tighten the tightening strap 103 at the end of the tightening end 101, preventing the installation opening 102 on its side from opening easily. This will also fix the entire corner protection structure to the corner of the metal railing.

[0029] This utility model uses a tightening and fixing method from the end to replace traditional adhesive to fix this protective structure at the corner of the metal railing. It is easy to install, and when the device needs to be replaced due to wear, dirt, aging, etc., the entire protective structure can be removed simply by unfastening the fixing buckle at the end. No dirt will remain on the metal railing, which helps to ensure the cleanliness of the metal railing.

[0030] Please see Figure 1 and Figure 2 The present invention relates to a metal railing corner protection structure, wherein a protective cylinder assembly 2 is installed on the side of the port tightening assembly 1, and a corner protection block 3 is fixedly connected to the end of the protective cylinder assembly 2.

[0031] Please see Figure 1 and Figure 4 The present invention discloses a corner protection structure for a metal railing. The protective cylinder assembly 2 includes a silicone protective cylinder 201. A second connecting piece 202 is fixedly connected to the side of the silicone protective cylinder 201.
