[0022] like Figures 1 to 4 As shown, a foldable building safety railing includes a base plate 1, with fixing ears 9 fixedly connected to both ends of the base plate 1. Sloping guide blocks 2 are fixedly connected to both sides of the top surface of the base plate 1. A snap-fit ​​hole 8 is provided at the center of the top of each of the two sloping guide blocks 2. A rotating shaft 3 is rotatably connected to the center of one side of each of the two sloping guide blocks 2. Connecting ears 4 are fixedly connected to both sides of each rotating shaft 3. A guardrail 5 is fixedly connected to the top of both connecting ears 4. The bottom of the guardrail 5 is higher than the top of the sloping guide blocks 2. Guide holes are provided at the center of the inner sides of both sides. Spring positioning grooves 10 are provided at the bottom of the two guide holes. Fixed pins 6 are slidably connected to the inner walls of the two guide holes. The diameter of the two fixed pins 6 is equal to the diameter of the snap-fit ​​hole 8. The positions of the two fixed pins 6 correspond to the positions of the snap-fit ​​hole 8. The two fixed pins 6 can be snapped and fixed with the snap-fit ​​hole 8. Spring baffles 11 are fixedly connected to the bottom of the two fixed pins 6. A return spring 12 is provided between the spring baffles 11 and the inner wall of the spring positioning groove 10.

[0023] As an optional technical solution of this utility model, the inclined surface of the inclined guide block 2 faces one side, and the top of the inclined surface of the inclined guide block 2 is in close contact with one side of the bottom of the guardrail 5. Fixing holes are provided on both sides of the fixing ear 9, so as to restrict the direction of the guardrail 5 from flipping and falling over by the inclined guide block 2, thereby improving the reliability of the protection.

[0024] As an optional technical solution of this utility model, the diameter of the spring baffle 11 is adapted to the diameter of the inner wall of the spring positioning groove 10, the length of the reset spring 12 after reset is adapted to the depth of the inner wall of the spring positioning groove 10, the reset spring 12 is sleeved on the outside of the fixing pin 6, and the reset spring 12 pushes the automatic locking into the locking hole 8, and can also press and fix, improving the stability of the locking.

[0025] As an optional technical solution of this utility model, after the fixing pin 6 is fully inserted into the inner wall of the snap-fit ​​hole 8, the spring baffle 11 is located at the bottom opening of the spring positioning groove 10. The top ends of both fixing pins 6 penetrate through the top of the guardrail 5. The top ends of the two fixing pins 6 are fixedly connected to a lifting handle 7.
