[0015] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] See Figures 1-12 This utility model provides a technical solution: Example: like Figures 1-4 As shown, a stainless steel railing includes a corrugated plate 1 and a connecting post 2. The corrugated plate 1 is provided with at least two flat recesses 3, which are fitted to the connecting post 2. The flat recesses 3 are detachably connected to the connecting post 2 through a connector.

[0017] The flat concave part 3 is provided with a first through hole, and the connecting column 2 is provided with a second through hole. The flat concave part 3 is connected to the connecting column 2 through the first through hole, the second through hole and the connector.

[0018] The connector includes a bolt 4 and a nut 5. The tail of the bolt 4 passes through the first through hole and the second through hole in sequence and is then connected to the nut 5.

[0019] Both the corrugated plate 1 and the column 2 are made of stainless steel.

[0020] The corrugated plate 1 is directly connected to the post 2 by setting the flat recess 3, bolt 4, and nut 5, eliminating the need for intermediate connecting parts and reducing the production cost of the guardrail. At the same time, the setting of the flat recess 3 can increase the stress area of ​​the corrugated plate 1 at the connection point and prevent the corrugated plate 1 from being damaged due to the stress concentrated on one point.

[0021] Example 2: like Figures 5-8 As shown, the difference between this embodiment and embodiment 1 is that the connecting member includes a locking post 6 disposed in the flat recess 3 and a locking buckle 7 disposed on the upright post 2. The locking buckle 7 is rotatably connected to the upright post 2. The locking buckle 7 is provided with an arc-shaped locking groove 8, and the locking post 6 is adapted to the locking groove 8.

[0022] The locking pin 6 is connected to the flat recess 3 via a connecting plate and screws.

[0023] The locking pin 6 is welded and fixed to the connecting plate.

[0024] The locking post 6 is provided with a snap-fit ​​groove 12, and the front end of the latch 7 is provided with a thin plate 13. When the post 2 is located in the locking groove 8, half of the thin plate 13 enters the snap-fit ​​groove 12, thereby limiting the axial movement of the locking post 6 (along the first through hole).

[0025] The locking pin 6 passes through the first through hole. When the flat recess 3 is in contact with the upright 2, the locking pin 6 passes through the upright 2 via the second through hole. At this time, rotating the latch 7 causes the sliding groove on the latch 7 to rotate until the locking pin 6 is located in the sliding groove, thus forming a stable connection between the locking pin 6 and the latch 7. When it is necessary to disassemble and replace the corrugated plate 1, simply rotating the latch 7 is sufficient to separate the locking pin 6 and the latch 7. This design improves the efficiency of disassembling and assembling the corrugated plate 1.

[0026] Example 3: like Figures 9-12 As shown, the difference between this embodiment and Embodiments 1 and 2 is that the connector includes a pin box 9 disposed in the flat recess 3 and a pin rod 10 disposed on the column 2. The pin rod 10 is slidably connected to the column 2 via a slide rail 11, and the end of the pin rod 10 extends into the pin box 9.

[0027] The slide rail 11 is fixed to the column 2 by screws. The end of the pin rod 10 is provided with a guide slope. The tail of the pin rod 10 is provided with a spring. One end of the spring is fixed to the tail of the pin rod 10, and the other end of the spring is fixed to the slide rail 11.

[0028] The pin box 9 passes through the first through hole. When the flat recess 3 is in contact with the column 2, the pin box 9 passes through the column 2 via the second through hole. During this process, the pin rod 10 first retracts under the action of the inclined surface and the pin box 9. When the hole and slot on the pin box 9 are coaxially aligned with the pin rod 10, the pin rod 10 automatically extends into the pin box 9 under the action of the spring, and the pin box 9 and the pin rod 10 form a stable connection. When it is necessary to disassemble and replace the corrugated plate 1, simply press the pin rod 10 back onto the slide rail 11 to separate the pin rod 10 from the pin box 9. This design can improve the efficiency of disassembly and assembly of the corrugated plate 1.

[0029] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
