Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of safety protection, especially relates to a building safety protection device. BACKGROUND

[0002] The design and application of building safety protection devices are key measures to ensure that buildings effectively respond to threats such as natural disasters, external attacks, and human sabotage during daily use. With the acceleration of urbanization and the development of building technology, the safety challenges faced by buildings are becoming increasingly complex. Therefore, the research and development of building safety protection devices have become an important field in building engineering. In the future, building safety protection devices will develop towards higher efficiency, greater durability, and greater comprehensiveness, providing more perfect safety protection and ensuring the safety of people's living and working environment.

[0003] After searching, the existing patent (publication number: CN222512710U) discloses a building safety protection device, which includes a plate body and a second sleeve rod. An inner cavity is formed in the interior of the plate body. A vertical shaft is rotatably installed in the interior of the inner cavity. A first bevel gear is fixed to the outer wall of the vertical shaft. A second bevel gear is engaged with the edge of the bottom of the first bevel gear. A horizontal shaft is fixed to the middle of one side of the second bevel gear. A first sleeve rod is nested through the side wall of the plate body at the end of the horizontal shaft. A support plate is fixed to the end of the first sleeve rod. This building safety protection device can make the two support plates move away from each other or move closer to each other by rotating the handle in the forward or reverse direction. The protection device can be fixed at the elevator entrance and will not be removed by naughty children. It can also be fixed at different size elevator entrances, improving the versatility of the protection device.

[0004] However, in the actual use process of the above-mentioned scheme, the sleeve rod is directly fixedly connected with the support plate. The connection between the sleeve rod and the support plate will directly bear external impact or pressure. When strong external force is encountered, the impact energy will be directly transmitted to the sleeve rod and the support plate, which may cause damage or failure to their structures, reducing the effectiveness of the protection device. At the same time, the connection between the sleeve rod and the support plate is relatively rigid, which may cause the building to be damaged quickly when it is subjected to sudden impact. For example, under strong vibration or impact, the fixed connection of the sleeve rod and the support plate may be broken or deformed, affecting the safety of the building.

[0005] Therefore, the utility model provides a building safety protection device. UTILITY MODEL CONTENTS

A guide wheel 33 is rotatably connected to the inner side of the support frame 32. The support frame 32 limits the guide wheel 33, allowing it to rotate inside the support frame 32. The guide wheel 33 is rotatably connected to the connecting rope 31, and the guide wheel 33 supports and guides the connecting rope 31.

[0031] The buffer assembly includes a connecting ring 25, which is fixedly connected to one end of a connecting rope 31, thus securing one end of the rope 31. A second transmission rod 24 is fixedly connected to the inner side of the connecting ring 25, thus securing the second transmission rod 24. A buffer rod 2 is slidably connected to the outer side of the second transmission rod 24, and the buffer rod 2 is fixedly connected to the outer wall of a support rod 1, thus supporting and securing the buffer rod 2. A second piston 22 is fixedly connected to the inner side of the second transmission rod 24, thus securing the second piston 22. The second piston 22 has evenly distributed fluid passage holes 23 on its inner side. By having multiple fluid passage holes 23 on the second piston 22, hydraulic oil can flow from one side of the second piston 22 to the other side. A spring 26 is fixedly connected to the outer wall of the second piston 22 near the second transmission rod 24. The spring 26 is fixed by the second piston 22. The other end of the spring 26 is fixedly connected to the inner wall of the buffer rod 2. The other side of the spring 26 is fixed by the buffer rod 2. A separator ring 21 is fixedly connected to the middle section of the inner wall of the buffer rod 2. The separator ring 21 separates the second piston 22.

[0032] The top support assembly includes a first liquid storage tank 11, which is located inside the support rod 1 and stores hydraulic oil. Two sections of the first piston 13 are slidably connected inside the first liquid storage tank 11, limiting the position of the first piston 13. A first transmission rod 14 is fixedly connected to the outer wall of the first piston 13 on the side away from each other, fixing the first transmission rod 14. A sealing ring 12 is slidably connected to the outer side of the middle section of the first transmission rod 14, and the sealing ring 12 is fixedly connected to the inner wall of the support rod 1, sealing the support rod 1 and the first transmission rod 14. The end of the first transmission rod 14 away from the first piston 13 is fixedly connected to a claw plate 15, fixing the claw plate 15. The sharp claws on the claw plate 15 can make the claw plate 15 more firmly and stably fixed to the external wall or ground.

[0033] The pressurizing assembly includes a pressurizing rod 4, which is fixedly connected to the outer wall of a support rod 1. The support rod 1 fixes the pressurizing rod 4. A second liquid storage tank 41 is provided on the inner side of the pressurizing rod 4 to store hydraulic oil. A threaded sleeve 42 is fixedly connected to the inner side of one end of the pressurizing rod 4, and the pressurizing rod 4 fixes the threaded sleeve 42. A lead screw 43 is threadedly connected to the inner side of the threaded sleeve 42, and the threaded sleeve 42 limits the lead screw 43. A handle 44 is slidably connected to the inner side of one end of the lead screw 43. The handle 44 is located on the lead screw 43. The screw 43 slides on the inner side of the screw 43, and the screw 43 can be rotated synchronously by rotating the handle 44. At the same time, the screw 43 can be raised and lowered by the limiting of the threaded sleeve 42. The other end of the screw 43 is rotatably connected to the outer side of the screw 43. The screw 43 drives the third piston 45 to rise and fall in the second liquid storage tank 41, thereby sucking the hydraulic oil stored in the second liquid storage tank 41. The third piston 45 is slidably connected to the second liquid storage tank 41. The pressure rod 4 is provided with a second through hole 46 at the connection position between the side away from the threaded sleeve 42 and the support rod 1.

[0034] The support rod 1 has a first through hole 16 connected to the second through hole 46 at the connection position. The first through hole 16 is connected to the second through hole 46, so that the hydraulic oil squeezed out by the third piston 45 can be transported into the first liquid storage tank 11 through the first through hole 16 and the second through hole 46, thereby squeezing the first pistons 13 on both sides and forcing the first pistons 13 to move to both sides at the same time, thereby locking the support rod 1 between the floors and fixing the equipment.

[0035] Specifically, when using this building safety protection device: First, pass the connecting rope 31 on the outside of the protective net 3 through the corresponding support frame 32 and connect it to the connecting ring 25. Then, erect the support rod 1 in the selected position. Next, rotate the screw 43 by the handle 44, thereby pushing the screw 43 towards the second through hole 46 through the limiting of the threaded sleeve 42. At the same time, the screw 43 pushes the third piston 45 to move synchronously, thereby pushing the hydraulic oil stored inside the second liquid storage tank 41. The hydraulic oil enters the inside of the first liquid storage tank 11 through the first through hole 16 of the second through hole 46, thereby squeezing the first pistons 13 at both ends inside the first liquid storage tank 11. This forces the first pistons 13 to drive the first transmission rod 14 and the claw plate 15 to move to both sides simultaneously, interacting with the outside. After the protective netting 3 is secured to the wall or ground, when it is impacted, the connecting rope 31 pulls the connecting ring 25. The connecting ring 25 then drives the second piston 22 to move away from the separating ring 21 via the second transmission rod 24. During this process, the hydraulic oil inside the buffer rod 2 flows from the side of the second piston 22 away from the separating ring 21 to the side of the separating ring 21 through the fluid passage 23. The hydraulic oil passing through the fluid passage 23 buffers the impact force, reducing the impact on the overall equipment. At the same time, the second piston 22 compresses the spring 26. After the impact disappears, the spring 26 pushes the second piston 22 towards the separating ring 21 with the buffer rod 2 as the stress point, thereby tightening the outer connecting rope 31.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
