DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] See Figure 1-5 An embodiment of the present invention provides a building construction guardrail, including a guard plate 1, a fixed block 2, a fixed shaft 3, a rotating rod 18, a support rod 15 and a support base 19.

[0024] The protection plate 1 is a plate-like structure or a fence-like structure.

[0025] The fixing block 2 is fixed to the back of the protective plate 1. There are two sets of fixing blocks 2, each containing two blocks. The two sets of fixing blocks 2 are fixed at the same height and fixed to the left and right sides of the protective plate 1, respectively. The two fixing blocks 2 in the same set are fixed at the same height and spaced a certain distance apart in the left-right direction. The right wall of the fixing block 2 in each set has a slot 12.

[0026] The fixed shafts 3 are horizontally fixed to the fixed blocks 2. The fixed shafts 3 are arranged in a left-right direction. There are two groups of fixed shafts 3, each with two fixed shafts. The two groups of fixed shafts 3 are fixed to two groups of fixed blocks 2, respectively. Both fixed shafts 3 in the same group are fixed between and to the two fixed blocks 2 in the same group.

[0027] The upper end of the rotating rod 18 is mounted on the fixed shaft 3 and is rotatable about the axis of the fixed shaft 3. The rotating rod 18 is a hollow structure, such as a cylindrical structure. The rotating rod 18 is perpendicular to the fixed shaft 3. The left and right upper ends of the rotating rod 18 are respectively mounted on the two fixed shafts 3 of the same set. Specifically, the left and right upper ends of the rotating rod 18 each have an opening, and the two fixed shafts 3 of the same set are respectively passed through the two openings. There are two rotating rods 18. The two rotating rods 18 are respectively mounted on the two sets of fixed shafts 3.

[0028] The support rod 15 is vertically arranged, and the upper end of the support rod 15 is connected to the lower end of the rotating rod 18. The support rod 15 is a hollow structure, such as a cylindrical structure. There are two support rods 15. The two support rods 15 are respectively connected to the two rotating rods 18.

[0029] The support base 19 is installed at the lower end of the support rod 15. There are two support bases 19. The two support bases 19 are installed with the two support rods 15 respectively.

[0030] The building construction guardrail may also include a curved plate 5. There are multiple, such as three, curved plates 5. Each curved plate 5 is coaxially arranged with the fixed shaft 3, and each curved plate 5 is arranged around the axis of the fixed shaft 3. Each curved plate 5 is arranged in the rotating rod 18, and each curved plate 5 can move along the radial direction of the fixed shaft 3, and separate from or conflict with the inner wall of the rotating rod 18, so that when each curved plate 5 makes a contraction movement along the radial direction of the fixed shaft 3, each curved plate 5 is separated from the inner wall of the rotating rod 18, and the rotating rod 18 can rotate. When each curved plate 5 makes an expansion movement along the radial direction of the fixed shaft 3, each curved plate 5 conflicts with the inner wall of the rotating rod 18, and the rotating rod 18 cannot rotate. There are two groups of curved plates 5, each group having the above-mentioned multiple. The two groups of curved plates 5 are respectively arranged in the two rotating rods 18.

[0031] The building construction guardrail may further include a cylinder 4 , a connecting rod 8 and a rotating shaft 9 .

[0032] Cylinder 4 is coaxially arranged with fixed shaft 3. Cylinder 4 is fixedly mounted between two fixed shafts 3 in the same group. Specifically, both ends of cylinder 4 are fixedly mounted on the two fixed shafts 3. Cylinder 4 is positioned within rotating rod 18. Curved plate 5 is positioned outside cylinder 4. There are two cylinders 4, one at each of the two groups of fixed shafts 3.

[0033] There are multiple, for example, three, connecting rods 8. Each connecting rod 8 is disposed radially of the fixed shaft 3 and arranged around the axis of the fixed shaft 3. Each connecting rod 8 extends through the side of the cylinder 4 and is movable radially of the cylinder 4. A first end of each connecting rod 8 is disposed within the cylinder 4, and a second end of each connecting rod 8 is fixedly connected to each curved plate 5, such that when each connecting rod 8 moves radially inward of the cylinder 4, each curved plate 5 contracts radially of the fixed shaft 3. When each connecting rod 8 moves radially outward of the cylinder 4, each curved plate 5 expands radially of the fixed shaft 3.

[0034] The rotating shaft 9 is coaxially arranged with the fixed shaft 3. The rotating shaft 9 passes through the fixed block 2 on the right, the fixed shaft 3 on the right, the right side of the rotating rod 18 and the right end of the cylinder 4, and can rotate around its own axis. The left end of the rotating shaft 9 is arranged inside the cylinder 4, and the right end is arranged outside the building construction guardrail. The left end of the rotating shaft 9 is connected to the first end of each connecting rod 8, and each connecting rod 8 can move radially along the fixed shaft 3, so that by operating the rotating shaft 9, each connecting rod 8 can move radially toward the inside of the cylinder 4 or toward the outside of the cylinder 4. There are two rotating shafts 9, and the two rotating shafts 9 are respectively arranged at the two groups of fixed shafts 3.

[0035] The building construction guardrail may also include a turntable 6. The turntable 6 is coaxially arranged with the rotating shaft 9. The turntable 6 is disposed within the cylinder 4 and is rotatable about its own axis. The turntable 6 is fixedly mounted on the first end of the rotating shaft 9. The turntable 6 has multiple arcuate chute 7, for example, three. The distance between the first end of each arcuate chute 7 and the outer ring of the turntable 6 is smaller than the distance between the second end of each arcuate chute 7 and the outer ring of the turntable 6. The first end of each connecting rod 8 is slidably mounted within each arcuate chute 7, such that when the turntable 6 rotates clockwise, the first end of each connecting rod 8 slides from the first end of each arcuate chute 7 to the second end of each arcuate chute 7, and each connecting rod 8 moves radially inward of the cylinder 4. When the turntable 6 rotates counterclockwise, the first end of each connecting rod 8 slides from the second end of each arcuate chute 7 to the first end of each arcuate chute 7, and each connecting rod 8 moves radially outward of the cylinder 4. Specifically, a connecting rod is slidably mounted within each arcuate chute 7, and the end of each connecting rod is fixedly connected to the first end of each connecting rod 8. There are two turntables 6, and the two turntables 6 are respectively disposed within the two cylinders 4.

[0036] The building construction guardrail may also include a stopper 20. There may be multiple, for example, three, stoppers 20. Each stopper 20 is arranged around the axis of the fixed shaft 3. Each stopper 20 is fixedly mounted on the inner wall of the cylinder 4 and in sliding contact with the outer ring of the turntable 6, thereby limiting the position of the turntable 6. There are two groups of stoppers 20, each group having the aforementioned multiple stoppers. The two groups of stoppers 20 are respectively disposed within the two cylinders 4.

[0037] The building construction guardrail may also include an anti-slip ring 10. The anti-slip ring 10 is coaxially arranged with the fixed shaft 3. The anti-slip ring 10 is sleeved over each of the curved plates 5, allowing the anti-slip ring 10 to contract or expand radially along the fixed shaft 3 under the influence of the curved plates 5, separating from or contacting the inner wall of the rotating rod 18. This anti-slip ring 10 increases the friction between each of the curved plates 5 and the inner wall of the rotating rod 18, thereby limiting the rotation of the rotating rod 18.

[0038] The building construction guardrail may also include a handle 11. Handle 11 is fixedly mounted to the second end of the rotating shaft 9, allowing workers to rotate the handle 11. When the anti-slip ring 10 contacts the inner wall of the rotating rod 18, resistance is felt at the handle 11. Specifically, the handle 11 is a rod-shaped structure. The handle 11 is arranged perpendicular to the rotating shaft 9. The first end of the handle 11 is fixedly mounted to the second end of the rotating shaft 9.

[0039] The building construction guardrail may further include a plug-in rod 13. The plug-in rod 13 secures the second end of the handle 11 to the back of the guard plate 1, so that when the anti-slip ring 10 contacts the inner wall of the rotating rod 18, the plug-in rod 13 limits the position of the handle 11, thereby preventing the anti-slip ring 10 from separating from the inner wall of the rotating rod 18 and the rotating rod 18 from shaking due to the handle 11 rotating on its own. Specifically, the plug-in rod 13 passes through the second end of the handle 11 and can slide left and right. The plug-in rod 13 can be inserted into the hole 12, so that when the plug-in rod 13 is inserted into the hole 12, the handle 11 cannot rotate, and when the plug-in rod 13 leaves the hole 12, the handle 11 can rotate.

[0040] The building construction guardrail may further include a ball head 14, a threaded rod 17, a swivel 16 and an insert rod.

[0041] The ball head 14 is fixed to the lower end of the rotating rod 18 and the lower end of the supporting rod 15. The ball head 14 has a plurality of holes, and the holes are densely arranged.

[0042] Threaded rod 17 is coaxially arranged with support rod 15. Threaded rod 17 is threadedly mounted within support rod 15. Threaded rod 17 can be inserted into the hole, so that when threaded rod 17 is inserted into the hole, the angle between support rod 15 and rotating rod 18 cannot be adjusted. When threaded rod 17 is removed from the hole, the angle between support rod 15 and rotating rod 18 can be adjusted. Because the holes on ball head 14 are located very close together, if threaded rod 17 is not inserted into a hole, it can be inserted by a small rotation angle without affecting the angle between support rod 15 and rotating rod 18.

[0043] The swivel 16 is coaxially arranged with the support rod 15. The swivel 16 is mounted on the support rod 15 and can rotate around its own axis. Optionally, the support rod 15 has an upper rod body and a lower rod body, and the upper rod body and the lower rod body are arranged at a certain distance in the up and down direction. The lower end outer ring of the upper rod body and the upper end outer ring of the lower rod body are connected by a plurality of connecting bars, and each connecting bar is arranged around the axis of the support rod 15. Each connecting bar protrudes outward from the support rod 15 to form a groove with an opening facing the inside of the support rod 15. The swivel 16 is arranged between the two rod bodies. The outer ring of the swivel 16 is in sliding contact with each connecting bar. The outer ring of the swivel 16 is embedded in the groove. The swivel 16 is threadedly connected to the threaded rod 17, so that by rotating the swivel 16, the threaded rod 17 is driven to insert into or leave the hole.

[0044] The rod is positioned vertically and fixedly mounted on the upper portion of the support base 19. The rod can be inserted into the hole, so that when the rod is inserted into the hole, the angle between the support base 19 and the support rod 15 cannot be adjusted. When the rod is removed from the hole, the angle between the support base 19 and the support rod 15 can be adjusted. Because the holes on the ball head 14 are located very close together, if the rod is not inserted into a hole, it can be inserted by a small rotation, without affecting the angle between the support rod 15 and the rotating rod 18.

[0045] In summary, the present invention provides a rotating rod 18 that can rotate around the axis of the fixed shaft 3, so that the angle between the rotating rod 18 and the protective plate 1 can be adjusted, so that the protective plate 1 can be set vertically or at an angle to the vertical plane, thereby playing a protective role in different directions, thereby expanding the application range of the building construction guardrail and allowing it to be used in different environments. In addition, in the present invention, the angle between the rotating rod 18 and the protective plate 1 is adjustable, the angle between the support rod 15 and the rotating rod 18 is adjustable, and the angle between the support base 19 and the support rod 15 is adjustable. Therefore, when the building construction guardrail is used in different environments, the protective plate 1 can be stably supported.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
