Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and more specifically, to an adjustable construction safety guardrail. Background Technology

[0002] As a crucial safety facility on buildings, construction safety railings play a key role in protection and isolation. The adjustable construction safety railing disclosed in Chinese patent application number CN222391175U is an innovation in the field of railings. The railing includes a railing body, with several mounting seats fixedly connected along the length of the end facing the ground. The railing body has a storage groove along the height direction, with two telescopic rods installed in the groove, and folding blades connected to the telescopic rods in the height direction. The advantage of the above solution is that when the telescopic rod extends and retracts into the storage slot, the folding blades extend accordingly, which can increase the overall height of the guardrail and make it flexible to be adjusted according to the construction environment, thus enhancing the adaptability of the guardrail height required by different construction environments. However, in actual use, simply adjusting the height is often insufficient to meet complex actual needs. Taking the protection of building pit foundations as an example, the excavation of the pit foundation changes the horizontal state of the foundation. When the guardrails installed along the slope of the pit foundation are connected to the guardrails in the horizontal position, the connection operation is extremely difficult because the two are not on the same plane. If the connection is forced, it is very easy to cause the guardrails to bend and be damaged. In addition, the existing guardrails and posts are mostly connected by bolts. During the construction of the pit foundation, the continuous vibration generated by the compaction of the foundation often causes the bolts to loosen, which in turn causes the guardrails to fall off. In view of the above problems, this application proposes a novel adjustable construction safety guardrail, which aims to solve the above problems. Utility Model Content

[0017] Please see Figures 1 to 4 An adjustable construction safety guardrail includes posts 3, with a left guardrail panel 1 and a right guardrail panel 2 fixedly connected between the posts 3. A turntable 5 is fixedly installed on one side of the left guardrail panel 1, and a rotating rod 7 is fixedly connected to the other side of the right guardrail panel 2. The rotating rod 7 is rotatably connected to the turntable 5, and this rotatable connection causes the left guardrail panel 1 and the right guardrail panel 2 to rotate. A connecting seat 9 is fixedly connected to the side of the rotating rod 7, and a pressure plate 11 is rotatably connected to the connecting seat 9. The plate 11 is rotated up and down to its front and back positions. One end of the pressure plate 11 is fixedly connected to a fixing rod 12, which is inserted into the turntable 5. The fixing rod 12 is inserted into the turntable 5 to fix and limit the rotating rod 7. A connecting pipe 16 is rotatably connected to the left guardrail 1, and a connecting rod 17 is rotatably connected to the right guardrail 2. One end of the connecting rod 17 is movably installed in the connecting pipe 16, and the connecting pipe 16 and the connecting rod 17 are slidably connected, so that it acts as a barrier structure in the gap after the left guardrail 1 and the right guardrail 2 are rotated and adjusted.

[0018] One end of the rotating rod 7 is fixedly connected to a turntable 8, and a connecting seat 9 is fixedly connected to the turntable 8. The turntable 8 and the connecting seat 9 are fixedly connected to maintain rotation in the same direction. A through hole 13 is provided on the turntable 8, which facilitates the connection of the fixing rod 12 through the turntable 8 and the positioning hole 6. Several positioning holes 6 are provided on the turntable 5. The fixing rod 12 passes through the through hole 13 and is inserted into the corresponding positioning hole 6. One end of the fixing rod 12 is inserted into the corresponding positioning hole 6, thereby fixing the position of the rotating rod 7 and the right guardrail 2.

[0019] A support rod 10 is fixedly connected to the connecting seat 9. A pressure plate 11 is rotatably connected to the support rod 10. The pressure plate 11 rotates back and forth around the support rod 10, so that one end of the pressure plate 11 can be raised and the other end can be lowered. A first spring 14 is provided between the pressure plate 11 and the turntable 8. The two ends of the first spring 14 are fixedly connected to the base plate 15. The two ends of the first spring 14 are fixedly connected to the pressure plate 11 and the turntable 8 respectively through the base plate 15. The first spring 14 pushes one end of the pressure plate 11 upward, so that the fixing rod 12 at the other end of the pressure plate 11 can be lowered into the positioning hole 6.

[0020] The other end of the connecting pipe 16 and the connecting rod 17 is fixedly connected to a first limiting plate 18. The first limiting plate 18 prevents the connecting pipe 16 and the connecting rod 17 from falling off. A first limiting groove 19 is opened on the connecting pipe 16. A first limiting block 20 is fixedly connected to the connecting rod 17. The first limiting block 20 is movably installed in the first limiting groove 19. The first limiting block 20 is slidably connected in the first limiting groove 19 to prevent the connecting rod 17 and the connecting pipe 16 from falling off each other.

[0021] The steps for using this utility model are as follows: When using this new type of guardrail, the left guardrail plate 1 and the right guardrail plate 2 can be respectively placed on the inclined ground and the horizontal ground near the pit foundation. One end of the pressure plate 11 is pressed down, causing the pressure plate 11 to rotate on the support rod 10. The first spring 14 is compressed, and the fixing rod 12 at the other end of the pressure plate 11 moves upward, exiting from the positioning hole 6 of the corresponding turntable 5. This releases the fixing constraint of the left guardrail plate 1 and the right guardrail plate 2. Then, either the left guardrail plate 1 or the right guardrail plate 2 is rotated. This application takes the rotation of the left guardrail plate 1 as an example. When the left guardrail plate 1 rotates, the turntable 5 and its positioning hole 6 rotate synchronously. When the left guardrail plate 1 rotates to the appropriate position, ... When the pressure plate 11 is released, the compressed spring 14 is released and pushes the pressure plate 11 back to its original position. This causes the fixing rod 12 at the other end of the pressure plate 11 to move downward, pass through the through hole 13 and insert into the corresponding positioning hole 6, thereby fixing the left guardrail 1. During the rotation of the left guardrail 1 and the right guardrail 2, the connecting pipe 16 and the connecting rod 17 rotate on the left guardrail 1 and the right guardrail 2 respectively, and the connecting rod 17 slides in the connecting pipe 16. The first limiting block 20 slides synchronously in the first limiting groove 19. Through the structure of the connecting rod 17 and the connecting pipe 16, the larger gap generated by the rotation of the left guardrail 1 and the right guardrail 2 acts as a barrier structure to prevent animals or people from passing through the larger gap. Example

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 The difference from embodiment 1 is that a connecting body 21 is fixedly connected to both sides of the post 3, and a hook plate 4 is fixedly connected to the other side of the left guardrail 1 and the right guardrail 2. The hook plate 4 is movably installed in the connecting body 21 and is snapped into the connecting body 21. Through the snapping of the hook plate 4 and the connecting body 21, the left guardrail 1 and the right guardrail 2 are fixedly connected to the post 3. A limit rod 26 is movably installed in the connecting body 21 above the hook plate 4. The limit rod 26 forms a blocking structure for the snapped left guardrail 1 and the right guardrail 2 to prevent them from moving.

[0023] The connector 21 has a reverse hook groove 22, and the hook plate 4 is movably installed in the reverse hook groove 22. The hook plate 4 and the reverse hook groove 22 are structurally corresponding to each other. After the hook plate 4 is inserted into the reverse hook groove 22, the two cannot move horizontally left or right.

[0024] The storage slot 23 and the second limiting slot 24 are formed on the connecting body 21. The storage slot 23 and the second limiting slot 24 are connected. The limiting rod 26 is movably installed in the storage slot 23. The limiting rod 26 moves telescopically within the storage slot 23. A second spring 25 is movably installed inside the storage slot 23 at the inner side of the limiting rod 26. The opening and compression of the second spring 25 provides the prerequisite for the telescopic movement of the limiting rod 26. A handle 27 is fixedly connected in the second limiting slot 24, and the lower end of the handle 27 is fixedly connected to the limiting rod 26. The handle 27 slides in the second limiting slot 24 and operates the limiting rod 26 to move synchronously.

[0025] The steps for using this utility model are as follows: When using this new type of guardrail, push the handle 27 on the corresponding connecting seat 9 on the post 3 to the side, so that the limiting rod 26 retracts into the storage groove 23, and the second spring 25 is compressed. Then, move the hook plate 4 on the corresponding left guardrail 1 or right guardrail 2 downward, and insert the hook plate 4 into the reverse hook groove 22. Then, release the handle 27, so that the compressed second spring 25 pushes the limiting rod 26 to open, so that the limiting rod 26 extends out and is locked above the hook plate 4, preventing the hook plate 4 from moving upward, thereby fixing and limiting the hook plate 4. This makes it easy for the left guardrail 1 or right guardrail 2 to connect with the post 3, and the operation is simple, quick, and not easy to fall off.
