Description

Technical Field

[0001] The utility model relates to the technical field of safety guardrails, in particular to a safety guardrail for buildings. Background Art

[0002] The safety guardrail for buildings is a device used to prevent and restrict the entry of personnel, items, vehicles, etc. into dangerous areas. In places such as construction sites, factories, and warehouses, in some areas such as high platforms, balconies, stairs, and corridors, there may be risks such as falling from heights, tipping over, and electric shock. The safety guardrail is set around these dangerous areas to protect personnel and items and prevent accidents.

[0003] Currently, when using a safety guardrail, it is generally directly placed in the designated area. However, since some current safety guardrails are integrally welded and formed, they cannot be adjusted in height according to the requirements of different construction sites for safety guardrails. Moreover, due to the different requirements of different construction sites for safety guardrails, for some requirements for higher guardrails, only the corresponding guardrails can be replaced, resulting in certain waste and costs. At the same time, using safety guardrails with inappropriate heights may lead to potential safety hazards at the construction site. Therefore, there is an urgent need for a safety guardrail for buildings to solve the above problems. Summary of the Utility Model

Detailed implementation manners

[0025] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model is given in conjunction with the accompanying drawings of the specification.

[0026] Refer to Figure 1-7 , which is the first embodiment of the present utility model, provides a safety guardrail for buildings. This safety guardrail for buildings includes a base 1, an outer guardrail 2 installed on the top of the base 1, support rods 3 installed on both sides of the base 1, fixed blocks 22 installed on both sides of the outer guardrail 2 for fixing with the support rods 3, an inner guardrail 21 installed inside the outer guardrail 2, a lifting member 4 installed inside the support rods 3, and a disassembling part 5 installed on the surface of the base 1;

[0027] The jacking member 4 includes a screw rod 41 rotatably connected inside the support rod 3. The bottom of the screw rod 41 is fixedly connected with a first bevel gear 42. The first bevel gear 42 is located inside the support rod 3 and is movably connected thereto. A second bevel gear 43 is installed on one side of the first bevel gear 42. One end of the second bevel gear 43 is fixedly connected with a knob 44. The knob 44 extends to the outside of the support rod 3 and is movably connected thereto. The first bevel gear 42 and the second bevel gear 43 are vertically arranged and meshed with each other. The surface of the knob 44 is provided with a rubber strip in an annular array for the convenience of operation by the operator. Since the rubber strip has viscosity and elasticity, a large frictional force can be generated. When the rubber strip contacts the hand, the surface of the rubber strip will form a certain contact area with the hand, increasing the contact surface between the two, thereby generating a large contact force and frictional force to prevent the occurrence of slipping.

[0028] The jacking member 4 further includes a slide rod 46 fixed inside the support rod 3. Sliders 45 are installed on the surfaces of both the slide rod 46 and the screw rod 41. The slider 45 is movably sleeved on the slide rod 46 and is threadedly connected to the screw rod 41. The slide rod 46 and the screw rod 41 are respectively installed inside the two support rods 3. The screw rod 41 is used to drive the inner guardrail 21, and the slide rod 46 is used to keep the inner guardrail 21 balanced.

[0029] A cavity 48 and a guide groove 471 are formed inside the outer guardrail 2. The cavity 48 communicates with the guide groove 471. The inner guardrail 21 is located inside the cavity 48 and is movably sleeved thereon. Guide strips 47 are fixedly connected to both sides of the inner guardrail 21. The guide strips 47 are located inside the guide groove 471 and are movably connected thereto, which can ensure the stability of the inner guardrail 21 during lifting.

[0030] Limit grooves 49 are formed on both sides of the outer guardrail 2. The other end of the slider 45 extends into the outer guardrail 2 through the limit groove 49 and is fixedly connected to the inner guardrail 21, which can drive the inner guardrail 21 to rise along the inside of the outer guardrail 2. At the same time, a chute for the lifting of the slider 45 is formed inside the support rod 3, which can prevent the slider 45 from shifting due to the rotation of the screw rod 41. And the guide strip 47 is located on the top of the slider 45, which can make the inner guardrail 21 rise stably without affecting the normal use of the slider 45.

[0031] The disassembly member 5 includes a reflector 51 installed on the surface of the base 1. Connecting plates 54 are installed on both sides of the reflector 51. A connecting bolt 52 is movably connected inside the connecting plate 54, which can facilitate the installation and disassembly of the reflector 51 and also facilitate the replacement of the reflector 51. And one end of the connecting bolt 52 has the same structure as the knob 44, which can enable quick driving of the connecting bolt 52 and avoid using external tools.

[0032] The surface of the base 1 is provided with a threaded groove 53. One end of the connecting bolt 52 extends into the threaded groove 53 and is threadedly connected thereto. Reflective strips are arranged at equal intervals on the surface of the support rod 3, which can improve the visible range of the driver.

[0033] During use, it can be adjusted according to the required height of the guardrail. During operation, rotate the knob 44 to drive the second bevel gear 43 to rotate. At the same time, since the second bevel gear 43 meshes with the first bevel gear 42, the second bevel gear 43 will drive the first bevel gear 42 to rotate during the rotation process, and at the same time drive the screw rod 41 to rotate. Since the screw rod 41 is threadedly connected to the slider 45, during the rotation of the screw rod 41, the slider 45 will be driven to rise, and at the same time, the slider 45 will drive the inner guardrail 21 along the chute inside the support rod 3 and the limit grooves 49 on both sides of the outer guardrail 2 to rise along the guide grooves 471 inside the outer guardrail 2 through the guide strips 47 on both sides thereof, so as to ensure the stability of the inner guardrail 21 during rising until the inner guardrail 21 is raised to the designated area. In this way, the overall height of the guardrail can be adjusted, avoiding waste of costs and further avoiding the occurrence of potential safety hazards at the construction site due to the non-adjustable height of the guardrail. Moreover, this method is simple to operate and does not require the assistance of other external equipment.

[0034] In addition, when the guardrail has been used for too long, the reflective plate 51 on its surface will be damaged to varying degrees. When the reflective plate 51 is damaged, the connecting bolt 52 can be directly rotated in the reverse direction to slowly separate it from the threaded groove 53 on the surface of the base 1 until the connection between the two is completely cancelled, and then the damaged reflective plate 51 can be disassembled. At the same time, a new reflective plate 51 is installed on the surface of the base 1, and one end of the connecting bolt 52 is located inside the threaded groove 53. Then rotate the connecting bolt 52 again to connect it to the threaded groove 53 to complete the replacement of the reflective plate 51. The replacement of the reflective plate 51 can timely maintain the surface reflective effect of the safety guardrail, reduce the visual blind area caused by the damage or aging of the reflective plate 51, improve the visibility of the safety guardrail, and thus improve the safety of the construction site.
