[0028] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0029] A building safety guardrail includes a fixed rod 1, two sets of connecting components 2 are sleeved on the outer side of the fixed rod 1, and the connecting components 2 are used to connect the utility model to an external protective frame. A telescopic railing 3 is fixedly connected between the two sets of fixed rods 1. The upper and lower ends of the two sets of fixed rods 1 are fixedly connected to telescopic rods 4. The lengths of the telescopic railings 3 and the telescopic rods 4 can be adjusted according to the distance between the protective frames.

[0030] First, see Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , the specific structure of the connection component 2 is as follows:

[0031] The connecting assembly 2 includes a collar 201, a front snap ring 202, a rear snap ring 203, a sleeve 204 and a plug rod 205. The collar 201 is sleeved on the outside of the fixed rod 1. The collar 201 and the fixed rod 1 are movably connected. The collar 201 can slide up and down and rotate on the outside of the fixed rod 1. The front snap ring 202 is rotatably connected to the outside of the collar 201. The rear snap ring 203 is rotatably connected to the outside of the collar 201 and is located behind the front snap ring 202. When the front snap ring 202 and the rear snap ring 203 are combined, a circular hole is formed on the inner side. The diameter of the circular hole is equal to the outer diameter of the steel pipe of the external protective frame. The sleeve 204 is fixedly connected to the right end of the front snap ring 202. The plug rod 205 It is slidably connected to the inner side of the outer sleeve 204, and the insertion rod 205 passes through the upper and lower ends of the sleeve 204. A socket 5 is provided at the right end of the rear snap ring 203. The socket 5 is adapted to be used with the insertion rod 205, so that the front snap ring 202 and the rear snap ring 203 can be fixed when closed. A spring 6 is sleeved on the outside of the insertion rod 205 and located inside the sleeve 204. A blocking block 7 is fixedly connected to the outside of the insertion rod 205 and located at the bottom end of the spring 6. The spring 6 can squeeze the blocking block 7 so that the blocking block 7 fixes the insertion rod 205 to the inner side of the socket 5, so that the insertion rod 205 and the socket 5 are firmly connected, thereby ensuring that the front snap ring 202 and the rear snap ring 203 will not loosen.

[0032] During use of the present invention, the insertion rod 205 is first manually pulled up. When the insertion rod 205 is pulled up, the blocking block 7 will squeeze the spring 6 until the insertion rod 205 is separated from the socket 5. Then the front snap ring 202 and the rear snap ring 203 are opened, and the front snap ring 202 and the rear snap ring 203 are clamped to the outside of the protective frame so that the insertion rod 205 is aligned with the socket 5. Then release your fingers, the spring 6 will push the blocking block 7 in the opposite direction, and the blocking block 7 will drive the insertion rod 205 to slide downward, thereby inserting the insertion rod 205 into the socket 5.

[0033] Second, see Figure 1 and Figure 4 , the specific structure of the telescopic railing 3 is as follows:

[0034] The telescopic railing 3 includes a slide 301, a sliding rod 302 and a vertical rod 303. The left and right groups of several groups of slides 301 are respectively fixedly connected to the outer sides of the fixed rods 1 on both sides. The slide rod 302 is slidably connected between the two adjacent groups of slides 301. The vertical rod 303 runs through the middle position of the slide rod 302, and the vertical rod 303 is fixedly connected to several rows of slide rods 302. During use of the utility model, the slide 301 and the slide rod 302 are connected to each other to form a telescopic cross bar, and several groups of vertical rods 303 and several groups of telescopic cross bars are staggered to form a mesh structure. Both ends of the mesh structure are fixed to the outer sides of the fixed rod 1, thereby forming effective protection.

[0035] For further information, see Figure 1 and Figure 4 A limiting sliding hole 8 is provided on the outer side of the slide cylinder 301, and the left and right ends of the slide rod 302 are fixedly connected to the limiting sliders 9. The limiting sliders 9 are slidably connected to the limiting sliding holes 8, so that the length of the telescopic railing 3 can be adjusted, and the cooperation between the limiting sliders 9 and the limiting sliding holes 8 can ensure the stable connection between the slide rod 302 and the slide cylinder 301, ensuring that the slide rod 302 will not separate from the slide cylinder 301.

[0036] Also, see Figure 1 and Figure 5 , the specific structure of the telescopic rod 4 is as follows:

[0037] The telescopic rod 4 includes an outer rod 401 and an inner rod 402. The left end of the outer rod 401 is fixedly connected to the outer side of the fixed rod 1, the inner rod 402 is sleeved on the inner side of the outer rod 401, and the right end of the inner rod 402 is fixedly connected to the fixed rod 1. A sliding hole 10 is provided on the outer side of the outer rod 401, and the left end of the inner rod 402 is fixedly connected to the blocking column 11, which is slidably connected to the sliding hole 10. The left end of the outer rod 401 is fixedly connected to the fixed rod 1 on the left, and the right end of the inner rod 402 is fixedly connected to the fixed rod 1 on the right, so that the distance between the fixed rods 1 at the left and right ends can be adjusted, which facilitates the installation of protective frames with different spacings.

[0038] For further information, see Figure 1 and Figure 5 The outer side of the lower group of the two groups of telescopic rods 4 is fixedly connected with a stabilizing card 12, and the bottom end of the stabilizing card 12 is provided with a card slot 13. During use of the utility model, the card slot 13 is stuck on the guardrail to increase the stability of the telescopic rod 4.

[0039] The working process of this utility model:

[0040] When the utility model is in use, the insertion rod 205 is first manually pulled up. When the insertion rod 205 is pulled up, the blocking block 7 will squeeze the spring 6 until the insertion rod 205 is separated from the socket 5. Then the front snap ring 202 and the rear snap ring 203 are opened, and the front snap ring 202 and the rear snap ring 203 are clamped to the outside of the protective frame, so that the insertion rod 205 is aligned with the socket 5. Then release your fingers, the spring 6 will push the blocking block 7 in the opposite direction, and the blocking block 7 will drive the insertion rod 205 to slide downward, thereby inserting the insertion rod 205 into the socket 5, thereby connecting the left fixed rod 1 to the protective frame. When disassembling, the installation process will be reversed to quickly The fixing rod 1 on the right side is quickly disassembled, and then the fixing rod 1 on the right side is pulled. The fixing rod 1 on the right side will drive the slide 301 and the inner rod 402 to move to the right at the same time. When the slide 301 moves to the right, the limit sliders 9 at the left and right ends of the slide rod 302 slide on the inner side of the limit slide hole 8. When the inner rod 402 moves to the right, the blocking column 11 slides on the inner side of the sliding hole 10, so that the distance between the fixing rods 1 at the left and right ends can be adjusted, which is convenient for the installation of protective frames with different spacings. Then, the connecting component 2 sleeved on the outside of the right fixing rod 1 is clipped onto the protective frame. The installation process is the same as above. The disassembly and assembly process is convenient and fast, and it is easy to disassemble and move, which improves work efficiency.
