Description

Technical Field

[0001] This utility model relates to the field of protective railing technology in construction engineering, specifically a safety protective railing for construction engineering. Background Technology

[0002] Building safety railings are barriers made of materials such as metal, plastic, wood, and glass, installed at building edges, openings, construction passages, and construction elevator entrances and exits during building construction and use, serving functions such as safety protection, area isolation, and warning guidance.

[0003] Currently, most common safety guardrails for construction projects on the market adopt a frame structure of posts and horizontal bars, which do not have the function of auxiliary support. They are prone to tipping over when blown by strong winds, and cannot play an effective protective role, thus failing to meet the usage requirements. Therefore, we propose a new type of safety guardrail for construction projects. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a construction safety guardrail with the advantage of anti-tipping function. This solves the problem that most common construction safety guardrails on the market adopt a frame structure of columns and horizontal bars, which do not have auxiliary support function and are prone to tipping over when blown by strong winds, thus failing to provide effective protection and meet the usage requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety guardrail for construction projects, comprising a shell, a connecting seat provided at the bottom of the inner wall of the shell, a protective plate movably connected to one side of the connecting seat, a lead screw movably connected to the top of the shell, a limit frame threadedly connected to the surface of the lead screw, and the bottom of the limit frame contacting the protective plate.

[0006] Preferably, both sides of the housing are fixedly connected to insert cylinders, and hollow rods are inserted into the inner cavities of the insert cylinders. Pins are provided on both the front and back sides of the insert cylinders. One side of the pin passes through the insert cylinder and the hollow rod in sequence and extends into the inner cavity of the hollow rod. A vertical plate is fixedly connected to the outer side of the pin. A fixing block is fixedly connected to one side of the vertical plate. A connecting frame is inserted into one side of the fixing block. One side of the connecting frame is fixedly connected to a limiting frame. A protective rod is inserted into one side of the hollow rod.

[0007] Preferably, the central shaft at the top of the inner cavity of the housing is movably connected to a lead screw via a bearing, and a rotating handle is fixedly connected to the top of the lead screw.

[0008] Preferably, slide rods are slidably connected to both sides of the inner cavity of the limiting frame, and the top of the slide rods is fixedly connected to the housing.

[0009] Preferably, a fixing rod is fixedly connected to the other side of the connecting seat, and both sides of the fixing rod are fixedly connected to the housing.

[0010] Preferably, the front and back of the housing are provided with movable grooves, and the two sides of the housing are provided with rectangular grooves.

[0011] Preferably, the top and bottom of the hollow rod's inner cavity are provided with sliding grooves, and a connecting plate is slidably connected to the inner cavity of the sliding groove. One side of the connecting plate is fixedly connected to the protective rod.

[0012] Preferably, a slot is provided on one side of the fixing block, and the slot is adapted to the connecting frame; an insertion hole is provided on one side of the hollow rod, and the insertion hole is adapted to the protective rod.

[0013] Compared with the prior art, this utility model provides a safety guardrail for construction projects, which has the following beneficial effects:

[0014] 1. When installing this utility model, rotating the handle causes the lead screw to rotate, which in turn causes the limiting frame to rise. When the limiting frame cannot rise, it will move away from the protective plate. At this point, the protective plate can be rotated so that one end of the protective plate contacts the ground. At this point, the protective plate is limited by the connecting seat and cannot rotate. Then, rotating the handle in the opposite direction causes the limiting frame to descend, thereby making the limiting frame contact the protective plate and limiting the protective plate. At this time, the operation of the protective plate increases the stability of the shell and makes the shell less likely to tip over.

[0015] 2. After the protective plate is adjusted, the hollow rod is inserted into the insert. Then, the pin is inserted through the insert and the hollow rod in sequence. At this time, the fixing block and the connecting frame are exactly aligned. Therefore, when the handle is rotated to lower the limiting frame, the limiting frame will also drive the connecting frame to lower, so that the connecting frame is inserted into the fixing block, thereby limiting the pin and making the hollow rod and the insert stable after connection.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0024] Please see Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a safety guardrail for construction engineering, including a shell 1. A connecting seat 3 is provided at the bottom of the inner wall of the shell 1. A protective plate 4 is movably connected to one side of the connecting seat 3. A lead screw 5 is movably connected to the top of the shell 1. A limit frame 7 is threadedly connected to the surface of the lead screw 5. The bottom of the limit frame 7 contacts the protective plate 4. The central axis at the top of the inner cavity of the shell 1 is movably connected to the lead screw 5 through a bearing 6. A rotating handle 18 is fixedly connected to the top of the lead screw 5. Sliding rods 8 are slidably connected to both sides of the inner cavity of the limit frame 7. The top of the sliding rods 8 is fixedly connected to the shell 1. A fixing rod 2 is fixedly connected to the other side of the connecting seat 3. Both sides of the fixing rod 2 are fixedly connected to the shell 1. Movable grooves 19 are provided on the front and back of the shell 1. Rectangular grooves are provided on both sides of the shell 1.

[0025] The specific function of this technical solution is as follows: During installation, rotating the handle 18 causes the lead screw 5 to rotate, which in turn causes the limiting frame 7 to rise. When the limiting frame 7 cannot rise, it will move away from the protective plate 4. At this time, the protective plate 4 can be rotated so that one end of the protective plate 4 contacts the ground. At this time, the protective plate 4 is limited by the connecting seat 3 and cannot rotate. Then, rotating the handle 18 in the opposite direction causes the limiting frame 7 to descend, thereby making the limiting frame 7 contact the protective plate 4 and thus limiting the protective plate 4. At this time, the operation of the protective plate 4 increases the stability of the shell 1, making the shell 1 less likely to tip over. Example

[0026] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the housing 1 has two fixedly connected inserts 9 on both sides. A hollow rod 10 is inserted into the inner cavity of the insert 9. Pins 11 are provided on the front and back of the insert 9. One side of the pin 11 passes through the insert 9 and the hollow rod 10 and extends into the inner cavity of the hollow rod 10. A vertical plate 12 is fixedly connected to the outer side of the pin 11. A fixing block 13 is fixedly connected to one side of the vertical plate 12. A connecting frame 14 is inserted into one side of the fixing block 13. One side of the connecting frame 14 is fixedly connected to the limiting frame 7. A protective rod 17 is inserted into one side of the hollow rod 10. Slide grooves 15 are provided at the top and bottom of the inner cavity of the hollow rod 10. A connecting plate 16 is slidably connected to the inner cavity of the slide groove 15. One side of the connecting plate 16 is fixedly connected to the protective rod 17. A slot is provided on one side of the fixing block 13 and is adapted to the connecting frame 14. An insertion hole is provided on one side of the hollow rod 10 and is adapted to the protective rod 17.

[0027] The specific function of this technical solution is as follows: After the position of the protective plate 4 is adjusted, the hollow rod 10 is inserted into the insert 9, and then the pin 11 is inserted through the insert 9 and the hollow rod 10 in sequence. At this time, the fixing block 13 and the connecting frame 14 are exactly aligned. Therefore, during the subsequent rotation of the handle 18 to lower the limiting frame 7, the limiting frame 7 will also drive the connecting frame 14 to lower, so that the connecting frame 14 is inserted into the fixing block 13, thereby limiting the pin 11 and making the hollow rod 10 and the insert 9 stable after connection.

[0028] Working principle: During installation, rotating the handle 18 causes the lead screw 5 to rotate, which in turn causes the limiting frame 7 to rise. When the limiting frame 7 cannot rise, it will move away from the protective plate 4. At this point, the protective plate 4 can be rotated so that one end of the protective plate 4 contacts the ground. At this point, the protective plate 4 is limited by the connecting seat 3 and cannot rotate. Then, rotating the handle 18 in the opposite direction causes the limiting frame 7 to descend, thereby making the limiting frame 7 contact the protective plate 4 and limiting the protective plate 4. At this time, the operation of the protective plate 4 increases the stability of the shell 1, making the shell 1 less likely to tip over.

[0029] After adjusting the position of the protective plate 4, the hollow rod 10 is inserted into the insert 9. Then, the pin 11 is inserted through the insert 9 and the hollow rod 10 in sequence. At this time, the fixing block 13 and the connecting frame 14 are exactly in line. Therefore, when the rotating handle 18 is rotated to lower the limiting frame 7, the limiting frame 7 will also drive the connecting frame 14 to lower, so that the connecting frame 14 is inserted into the fixing block 13, thereby limiting the pin 11 and making the hollow rod 10 stable after being connected to the insert 9.
