Description

Technical Field

[0001] This invention relates to the field of guardrail technology, and in particular to a safety guardrail. Background Technology

[0002] Guardrails are large railings that serve a protective function. Currently, there are many types of guardrails, some used in factories, some on balconies, and some on highways. Guardrails used on highways are mainly used to protect vehicles and prevent serious traffic accidents.

[0003] Regarding the existing safety guardrails used on highways:

[0004] First, when a vehicle accident occurs, the pipes (cylinders) used to fix the guardrail to the soil may deform and develop dents, which affects the guardrail's protective ability. If it is removed and repaired, it will take a long time and have low practicality. Second, spikes are installed on the guardrail to prevent people from climbing over it. These spikes can easily injure workers when installing the guardrail. Summary of the Invention

[0005] In view of this, the present invention provides a safety guardrail, which has a fixing part. Through the setting of the fixing part, a threaded plate is threadedly connected to the threaded rod, and two threaded grooves are symmetrically opened on the outer wall of the threaded plate. Two first locking screws are threadedly connected to the cylindrical tube. When the top surface of the threaded plate is flush with the top surface of the cylindrical tube, the threaded groove and the first locking screw are horizontally flush. During use, when the first locking screw is connected to the threaded groove, the fixing head can be moved upward by rotating the threaded rod counterclockwise, which can correct the pit on the cylindrical tube.

[0006] It also features a protective section. Because there are two sliding rods, both slidably connected to the protective frame, with the upper end of each rod welded to a baffle located above the spikes, the baffles prevent injury to workers during transport. Furthermore, the protective frame is threaded with two second locking screws, the rear ends of which contact the outer walls of the two sliding rods, locking them in place. The top surface of the baffle has a linear array of circular through holes that align with the spikes. During use, the second locking screws can be loosened, allowing the baffle to contact the top surface of the protective frame, enabling the spikes to function normally.

[0007] The purpose and effect of the safety guardrail of this invention are achieved by the following specific technical means:

[0008] This invention provides a safety guardrail, specifically comprising: a columnar tube, a fixing part, and a protective part; two columnar tubes are provided, both being cylindrical tubular structures, and both are pre-buried in the soil; the fixing part consists of a fixing head, a threaded rod, a threaded plate, a first locking screw, and a threaded groove, with the fixing head slidably connected inside the columnar tube; each fixing head has a threaded rod welded to its top surface, and the bottom surface of the fixing head has a pointed structure, with the lower half of the fixing head inserted into the soil, serving as an auxiliary fixing structure for the columnar tube; a protective plate is installed on the columnar tube, and a protective part is installed on the protective plate; the protective part consists of a sliding rod, a baffle, a second locking screw, and a through hole.

[0009] Furthermore, the outer walls of the two fixing heads respectively contact the inner walls of the two cylindrical tubes, and the top surfaces of the two fixing heads are both hemispherical structures, with the fixing heads serving as a correction structure for the cylindrical tubes.

[0010] Furthermore, a threaded plate is threadedly connected to the threaded rod, and two threaded grooves are symmetrically opened on the outer wall of the threaded plate;

[0011] The cylindrical tube is threaded with two first locking screws. When the top surface of the threaded plate is flush with the top surface of the cylindrical tube, the thread groove is flush with the first locking screw in the horizontal direction.

[0012] Furthermore, each of the cylindrical tubes is welded with two sleeves, and each sleeve is fitted with a connecting arm, which is a concave bent rod structure.

[0013] The protective plate is a rectangular plate structure. Two connecting seats are symmetrically welded on the left and right ends of the protective plate. The connecting seats are plugged into the connecting arms. The connecting seats are fitted with pins for locking.

[0014] Furthermore, a protective frame is welded to the rear end face of the protective plate. The protective frame is made of seven directional tubes welded together and serves as a reinforcing structure for the protective plate.

[0015] Furthermore, the top surface of the protective frame is welded with spikes in a linear array, and the spikes welded in a linear array together form the anti-climbing structure of the protective plate.

[0016] Furthermore, two connecting blocks are symmetrically welded to the rear end face of the protective frame. The connecting blocks are rectangular block structures, and each connecting block has a circular hole. An auxiliary tube is inserted into the two circular holes.

[0017] The auxiliary tube is a cylindrical tubular structure, with its outer wall in contact with the inner wall of the circular hole. The auxiliary tube is a reinforcing structure of the protective plate.

[0018] Furthermore, there are two sliding rods, both of which are slidably connected to the protective frame. The upper end of each sliding rod is welded to a baffle, which is located above the spike.

[0019] Furthermore, the protective frame is threaded with two second locking screws, one rear end of each of the two second locking screws is in contact with the outer wall of the two sliding rods, and the two sliding rods are in a locked state.

[0020] The top surface of the baffle has through holes arranged in a linear array. The through holes are circular holes that match the spikes and are aligned with each other.

[0021] Beneficial effects

[0022] This application utilizes a fixed structure where each fixing head has a threaded rod welded to its top surface and a pointed bottom surface. The lower half of the fixing head is inserted into the soil, serving as an auxiliary fixing structure for the cylindrical tube. This improves the fixing effect of the cylindrical tube and thus enhances its resistance to vehicle impacts. When the cylindrical tube is dented after being hit by a vehicle, a threaded plate is threaded onto the threaded rod, with two symmetrical threaded grooves on its outer wall. Two first locking screws are threaded onto the cylindrical tube. When the top surface of the threaded plate is flush with the top surface of the cylindrical tube, the threaded grooves and the first locking screws are horizontally aligned. During use, after the first locking screws connect to the threaded grooves, rotating the threaded rod counterclockwise moves the fixing head upward, thus correcting the dent on the cylindrical tube.

[0023] Furthermore, the protective features include two sliding rods slidably connected to the protective frame, with the upper ends of both rods welded to a baffle located above the spikes. This baffle prevents injury to workers during transport. Additionally, the protective frame is threaded with two second locking screws, the rear ends of which contact the outer walls of the two sliding rods, locking them in place. The top surface of the baffle has a linear array of circular through holes that align with the spikes. During use, the second locking screws can be loosened, allowing the baffle to contact the top surface of the protective frame, enabling the spikes to function normally.

[0024] Furthermore, through the arrangement of connecting seats, protective frames, spikes, connecting blocks, and auxiliary tubes, each cylindrical tube is welded with two sleeves, and each sleeve is fitted with a connecting arm, which is a concave bent rod structure. The protective plate is a rectangular plate structure, with two connecting seats symmetrically welded to its left and right ends. The connecting seats are connected to the connecting arms, and the connecting seats are fitted with pins for locking, allowing for easy removal of the protective plate during maintenance. Additionally, a protective frame is welded to the rear end of the protective plate. This protective frame, composed of seven directional tubes, serves as a reinforcing structure for the protective plate, improving its impact resistance during use. In addition to its protective capabilities, the top surface of the protective frame is welded with spikes in a linear array, which together form the anti-climbing structure of the protective plate, preventing people from climbing over it during use and thus avoiding traffic accidents. Furthermore, the rear end of the protective frame is symmetrically welded with two connecting blocks, which are rectangular blocks with a circular hole in each block. An auxiliary tube is inserted into each of the two circular holes. The auxiliary tube is a cylindrical tube with its outer wall in contact with the inner wall of the circular hole. The auxiliary tube is a reinforcing structure of the protective plate, and it can be installed in accident-prone sections of road to enhance the protective capabilities of the protective plate.

[0038] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0039] Example: Please refer to Figures 1 to 8 :

[0040] This invention proposes a safety guardrail, comprising: a columnar tube 1, a fixing part 2, and a protective part 4;

[0041] There are two cylindrical tubes 1 in total. Both cylindrical tubes 1 are cylindrical tubular structures and are pre-buried in the soil.

[0042] The fixing part 2 consists of a fixing head 201, a threaded rod 202, a threaded plate 203, a first locking screw 204, and a threaded groove 205. The fixing head 201 is slidably connected inside the cylindrical tube 1.

[0043] A protective plate 3 is installed on the top, and a protective part 4 is installed on the protective plate 3;

[0044] The protective part 4 consists of a sliding rod 401, a baffle 402, a second locking screw 403, and a through hole 404.

[0045] Each fixing head 201 has a threaded rod 202 welded to its top surface. The bottom surface of the fixing head 201 has a pointed structure. The lower half of the fixing head 201 is inserted into the soil. The fixing head 201 is an auxiliary fixing structure for the cylindrical tube 1. This can improve the fixing effect of the cylindrical tube 1, and thus improve the resistance to vehicle impact.

[0046] The outer walls of the two fixing heads 201 are in contact with the inner walls of the two cylindrical tubes 1 respectively. The top surfaces of the two fixing heads 201 are hemispherical structures. The fixing heads 201 are correction structures for the cylindrical tubes 1. When the cylindrical tubes 1 have dents due to collisions, the fixing heads 201 are adjusted. At this time, the dents on the cylindrical tubes 1 can be corrected by the squeezing of the fixing heads 201.

[0047] Among them, a threaded plate 203 is threadedly connected to the threaded rod 202, and two threaded grooves 205 are symmetrically opened on the outer wall of the threaded plate 203.

[0048] Two first locking screws 204 are threaded onto the cylindrical tube 1. When the top surface of the threaded plate 203 is flush with the top surface of the cylindrical tube 1, the threaded groove 205 is flush with the first locking screw 204 in the horizontal direction. During use, after the first locking screw 204 is connected to the threaded groove 205, rotating the threaded rod 202 counterclockwise can move the fixed head 201 upward, which can correct the pit on the cylindrical tube 1.

[0049] Each cylindrical tube 1 has two sleeves 101 welded on it, and each sleeve 101 has a connecting arm 102 inserted into it. The connecting arm 102 is a concave bent rod structure.

[0050] The protective plate 3 is a rectangular plate structure. Two connecting seats 301 are symmetrically welded to the left and right ends of the protective plate 3. The connecting seats 301 are plugged into the connecting arm 102. The connecting seats 301 are plugged into a pin for locking the connecting seats 301, so that the protective plate 3 can be easily removed during maintenance.

[0051] Among them, a protective frame 302 is welded to the rear end face of the protective plate 3. The protective frame 302 is made of seven directional tubes welded together. The protective frame 302 is a reinforcing structure of the protective plate 3, which can improve the impact resistance and protection capability of the protective plate 3 during use.

[0052] Among them, the top surface of the protective frame 302 is welded with spikes 303 in a linear array. The spikes 303 welded in a linear array together form the anti-climbing structure of the protective plate 3, which can prevent people from climbing over it during use, thus avoiding traffic accidents.

[0053] Among them, the rear end face of the protective frame 302 is symmetrically welded with two connecting blocks 304. The connecting blocks 304 are rectangular block structures. Each of the two connecting blocks 304 has a circular hole, and an auxiliary tube 305 is inserted into the two circular holes.

[0054] The auxiliary tube 305 is a cylindrical tubular structure. The outer wall of the auxiliary tube 305 is in contact with the inner wall of the circular hole. The auxiliary tube 305 is a reinforcing structure of the protective plate 3. The auxiliary tube 305 can be installed in sections of road where traffic accidents occur to enhance the protective capability of the protective plate 3.

[0055] There are two sliding rods 401, both of which are slidably connected to the protective frame 302. The upper end of each sliding rod 401 is welded to the baffle 402. The baffle 402 is located above the spike 303. Therefore, the baffle 402 can prevent the spike 303 from injuring the workers during handling.

[0056] Among them, the protective frame 302 is threaded with two second locking screws 403, and the rear end of the two second locking screws 403 respectively contacts the outer wall of the two sliding rods 401, and the two sliding rods 401 are in a locked state.

[0057] The top surface of the baffle 402 has through holes 404 arranged in a linear array. The through holes 404 are circular holes that match the spikes 303. The positions of the through holes 404 and the spikes 303 are aligned. When in use, the second locking screw 403 can be loosened. At this time, the baffle 402 contacts the top surface of the protective frame 302, and the spikes 303 function normally.

[0058] The specific usage and function of this embodiment are as follows:

[0059] During fixing, first bury the two cylindrical tubes 1 in the soil, and then tap the threaded rod 202. At this time, the two fixing heads 201 are also inserted into the soil. Since each fixing head 201 has a threaded rod 202 welded to its top surface and a pointed structure at the bottom surface, the lower half of the fixing head 201 is inserted into the soil. The fixing head 201 is an auxiliary fixing structure for the cylindrical tubes 1, which can improve the fixing effect of the cylindrical tubes 1 and thus improve the resistance to vehicle impact.

[0060] When the cylindrical tube 1 is dented after being hit by a vehicle, a threaded plate 203 is threadedly connected to the threaded rod 202. Two threaded grooves 205 are symmetrically opened on the outer wall of the threaded plate 203. Two first locking screws 204 are threadedly connected to the cylindrical tube 1. When the top surface of the threaded plate 203 is flush with the top surface of the cylindrical tube 1, the threaded grooves 205 and the first locking screws 204 are horizontally flush. During use, when the first locking screws 204 are connected to the threaded grooves 205, rotating the threaded rod 202 counterclockwise can move the fixed head 201 upward, thus correcting the dent on the cylindrical tube 1.

[0061] During use, a protective frame 302 is welded to the rear end face of the protective plate 3. The protective frame 302 is made of seven directional tubes welded together. The protective frame 302 is a reinforcing structure of the protective plate 3, which can improve the impact resistance and protection capability of the protective plate 3 during use. Furthermore, the top surface of the protective frame 302 is welded with spikes 303 in a linear array. The spikes 303 welded together in a linear array form an anti-climbing structure of the protective plate 3, which can prevent people from climbing over it during use, thus preventing traffic accidents. Furthermore, two connecting blocks 304 are symmetrically welded to the rear end face of the protective frame 302. The connecting blocks 304 are rectangular block structures. Each of the two connecting blocks 304 has a circular hole, and an auxiliary tube 305 is inserted into the two circular holes. The auxiliary tube 305 is a cylindrical tubular structure. The outer wall of the auxiliary tube 305 contacts the inner wall of the circular hole. The auxiliary tube 305 is a reinforcing structure of the protective plate 3. In sections of road with frequent traffic accidents, the auxiliary tube 305 can be installed to enhance the protection capability of the protective plate 3.

[0062] During transportation and installation, since there are two sliding rods 401, both of which are slidably connected to the protective frame 302, and the upper end of each sliding rod 401 is welded to the baffle 402, which is located above the spike 303, the baffle 402 can prevent the spike 303 from injuring workers during handling. Furthermore, the protective frame 302 is threaded with two second locking screws 403. The rear end of 3 contacts the outer wall of the two sliding rods 401 respectively, and the two sliding rods 401 are locked; the top surface of the baffle 402 has through holes 404 in a linear array. The through holes 404 are circular holes and match the spikes 303. The positions of the through holes 404 and the spikes 303 are aligned. When in use, the second locking screw 403 can be loosened. At this time, the baffle 402 contacts the top surface of the protective frame 302, and the spikes 303 function normally.

[0063] During maintenance, each cylindrical tube 1 has two sleeves 101 welded on it, and each sleeve 101 has a connecting arm 102 inserted into it. The connecting arm 102 is a concave bent rod structure. The protective plate 3 is a rectangular plate structure. The left and right ends of the protective plate 3 are symmetrically welded with two connecting seats 301. The connecting seats 301 are inserted into the connecting arms 102. The connecting seats 301 are fitted with pins for locking the connecting seats 301. The protective plate 3 can be easily removed during maintenance.
