Description

Technical Field

[0001] The utility model relates to the field of road traffic, and specifically relates to a large-flow traffic safety isolation fence. Background Art

[0002] Traffic safety barriers are mainly used to divert vehicles on roads with high traffic volume. They mainly protect the safety of pedestrians and vehicles. The barriers can effectively isolate traffic flow and prevent vehicles from colliding or even causing accidents due to overtaking, borrowing lanes, etc. However, traffic roads have a certain curvature. When using barriers on curved roads, straight barriers cannot fully fit the curved roads, which can easily reduce the road space. Straight barriers cannot be bent into an arc, which is not convenient for isolation on curved roads. In addition, the barriers are too light and can easily be moved or tipped over by external forces (wind), resulting in instability. Utility Model Content

[0003] The present invention provides a large-volume traffic safety isolation fence, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A high-volume traffic safety isolation fence, comprising a rubber strip, a plastic seat, a deformable structure, a railing and a support column, wherein the deformable structure and the rubber strip are arranged parallel to each other at the upper and lower ends of the railing, the rubber strip and the left and right ends of the deformable structure are respectively arranged on the sides of the two support columns, and the lower ends of the two support columns are provided with the plastic seat to contact the ground;

[0006] The deformation structure is provided with a movable bar, a support structure, a first spring, a curved plate and a fixed plate. The support structure is provided with two and symmetrically arranged in the fixed plate. The first spring is provided with two, one end of each of the first springs is respectively arranged on the side of the curved plate, and the other end of each of the first springs is obliquely arranged in the support structure. The movable bar is arranged parallel to the curved plate.

[0007] The left and right ends of the movable bar and the bending plate are respectively arranged on the outside of the two support columns, and the left and right sides of the fixed plate are arranged on the outside of the support columns. The two support structures are translated toward the support columns in the fixed plate, and the support structures pull the two first springs to stretch left and right.

[0008] A better technical solution: the bending plate is made of plastic material, and a section of rubber material is provided on the left and right sides of the bending plate. When the bending plate bends, the rubber material and the support column are deformed and stretched, and the movable bar is consistent with the length of the bending plate when it is stationary, and has the characteristics of strong toughness and easy bending and deformation. When the support structure is close to the middle position of the fixed plate, the first spring is in a stationary state, and the left and right sides of the support structure are in contact with the outside of the support column.

[0009] A preferred technical solution: the movable bar is provided with a pull plate, a rubber block, and a connecting block. The rubber blocks are arranged on the left and right sides of several connecting blocks, and the rubber blocks are arranged on the side of the support column. The side of the connecting block has the pull plate arranged on the curved plate. The rubber block and the connecting block are arranged equidistantly. The railing is arranged on the side of the connecting block, and several connecting blocks and the rubber block are equidistantly scaled.

[0010] A preferred technical solution: the pulling plate is made of rubber material, the middle of the bending plate is squeezed and bent toward the fixed plate, and drives the connecting block and the rubber block to stretch each other.

[0011] A better technical solution: the support structure is provided with a handle, a block, a bearing ring, a second spring, a baffle and a slide groove, the bearing ring slides in the slide groove in the fixed plate, the baffle is arranged on the outside of the handle, and the handle and the internal bearing of the bearing ring rotate, the left and right ends of the second spring are respectively arranged between the bearing ring and the support column, the upper and lower sides of the slide groove have the blocks arranged equidistantly and the blocks are arranged on the side of the fixed plate, and the blocks are pressed against the baffle in the vertical state, the handle protrudes from the surface of the fixed plate, and the baffle passes through the blocks arranged on both sides of the slide groove in the horizontal state.

[0012] A better technical solution: the support column is provided with a cap, a conical metal block, a support plate, a triangular plate and a shell, the cap is arranged at the top of the shell, the support plate is attached to the outer side of the middle part of the conical metal block and the inner side of the shell, four triangular plates are arranged on the outer side of the lower part of the shell, and the triangular plates are arranged inside the plastic seat. When the shell is subjected to lateral thrust, the shell tilts to one side and causes the triangular plates to press against the plastic seat.

[0013] A better technical solution: the lowest point of the conical metal block and the lowest point of the plastic seat are located on the same horizontal line, the support plate is made of rubber, and the support plate pulls the shell elastically for buffering under the gravity of the conical metal block.

[0014] Compared with the existing technology, this technical solution has the following advantages:

[0015] In the utility model, the handle is rotated to make the baffle in a horizontal state, and the handles on the two supporting structures are pulled toward the supporting column. When the two handles move, the two handles drive the two first springs connected to the bearing ring to stretch outward, and the first spring drives the middle of the bent plate to move toward the fixed plate. At this time, the bent plate bends in an arc, and the bent plate drives the pulling plate connected to it to bend in an arc, so that the connecting block stretches the rubber block in an arc, and the railings connected to the connecting block are equidistantly extended and retracted, and the rubber strip is pushed and deformed by the railings, so that the deformation structure, railings and rubber strip are bent in an arc, which is convenient for shape isolation of arc curves in high-volume traffic.

[0016] In the present invention, the plastic seat is placed on a horizontal road surface. When the shell is subjected to a lateral force, the shell presses against one side of the plastic seat through the triangular plate, and one side of the shell generates a pressing force toward the ground. At this time, the support plate tilts along with the shell and causes the conical metal block to also generate a pressing force toward the ground. Therefore, the lateral force is shared by the conical metal block and the triangular plate. Moreover, since the conical metal block is located in the middle of the shell, when the shell drives the support plate to tilt, the gravity of the conical metal block causes the shell to press against the ground in the opposite direction to form a reverse blocking force, and reversely blocks the lateral force of the shell, thereby enhancing the resistance to external force and preventing it from being easy to tip over and unstable.

[0028] like Figures 1 to 5 As shown, the present invention proposes a large-volume traffic safety isolation fence, including a rubber strip 1, a plastic seat 2, a deformable structure 3, a railing 4 and a support column 5. The deformable structure 3 and the rubber strip 1 are arranged parallel to each other at the upper and lower ends of the railing 4. The left and right ends of the rubber strip 1 and the deformable structure 3 are respectively arranged on the sides of the two support columns 5. The lower ends of the two support columns 5 are provided with the plastic seat 2 to contact the ground;

[0029] The deformation structure 3 includes a movable bar 31, a support structure 32, a first spring 33, a curved plate 34, and a fixed plate 35. The support structures 32 are provided with two and are symmetrically arranged in the fixed plate 35. There are two first springs 33, one end of each of the first springs 33 is respectively arranged on the side of the curved plate 34, and the other end of each of the first springs 33 is obliquely arranged in the support structure 32. The movable bar 31 is arranged parallel to the curved plate 34.

[0030] The left and right ends of the movable bar 31 and the bending plate 34 are respectively arranged on the outside of the two support columns 5, and the left and right sides of the fixed plate 35 are arranged on the outside of the support columns 5. The two support structures 32 are translated toward the support columns 5 in the fixed plate 35, and the support structures 32 pull the two first springs 33 to stretch left and right.

[0031] Among them, the bending plate 34 is made of plastic material, and a section of rubber material is provided on the left and right sides of the bending plate 34. When the bending plate 34 bends, the rubber material and the support column 5 are deformed and stretched, and the movable bar 31 is consistent with the length of the bending plate 34 when it is in a stationary state, and has the characteristics of strong toughness and easy bending and deformation. When the support structure 32 is close to the middle position of the fixed plate 35, the first spring 33 is in a stationary state, and the left and right sides of the support structure 32 are in contact with the outside of the support column 5.

[0032] Among them, the movable bar 31 is provided with a pull plate 311, a rubber block 312, and a connecting block 313. The rubber block 312 is arranged on the left and right sides of several of the connecting blocks 313, and the rubber block 312 is arranged on the side of the support column 5. The side of the connecting block 313 has the pull plate 311 arranged on the curved plate 34. The rubber block 312 and the connecting block 313 are arranged equidistantly. The railing 4 is arranged on the side of the connecting block 313, and several of the connecting blocks 313 and the rubber block 312 are equidistantly scaled.

[0033] Furthermore, the pulling plate 311 is made of rubber, and the middle of the bending plate 34 is squeezed and bent toward the fixing plate 35 , thereby driving the connecting block 313 and the rubber block 312 to stretch each other.

[0034] Among them, the support structure 32 is provided with a handle 321, a block 322, a bearing ring 323, a second spring 324, a baffle 325 and a slide groove 326. The bearing ring 323 slides in the slide groove 326 in the fixed plate 35, and the baffle 325 is arranged on the outside of the handle 321, and the handle 321 rotates with the internal bearing of the bearing ring 323. The left and right ends of the second spring 324 are respectively arranged between the bearing ring 323 and the support column 5. The slide groove 326 has the blocks 322 arranged equidistantly on the upper and lower sides, and the blocks 322 are arranged on the side of the fixed plate 35, and the blocks 322 are pressed against the baffle 325 in the vertical state. The handle 321 protrudes from the surface of the fixed plate 35, and the baffle 325 passes through the blocks 322 arranged on both sides of the slide groove 326 in the horizontal state.

[0035] The handle 321 is rotated to make the baffle 325 in a horizontal state, and the handles 321 on the two support structures 32 are pulled toward the support column 5, so that the bearing ring 323 slides in the sliding groove 326, and the bearing ring 323 drives the second spring 324 to compress the support column 5, and then the handle 321 is rotated to make the baffle 325 in a vertical state and engage between the stoppers 322, thereby fixing the compression of the bearing ring 323 and the second spring 324, and the bearing ring 323 fixes the tension of the first spring 33. Therefore, when the two handles 321 are moved, the two The handle 321 drives the two first springs 33 connected to the bearing ring 323 to stretch outward, and the first spring 33 drives the middle of the bending plate 34 to move toward the fixed plate 35. At this time, the bending plate 34 bends in an arc, and the bending plate 34 drives the pulling plate 311 connected to it to bend in an arc, so that the connecting block 313 stretches the rubber block 312 in an arc, and the railing 4 connected to the connecting block 313 is equidistantly extended and retracted, and the rubber strip 1 is pushed and deformed through the railing 4, so that the deformation structure 3, the railing 4 and the rubber strip 1 are bent in an arc, which is convenient for the shape isolation of the arc curve in high-volume traffic.

[0036] Among them, the support column 5 is provided with a cap 51, a conical metal block 52, a support plate 53, a triangular plate 54 and a shell 55. The cap 51 is arranged at the top of the shell 55, and the support plate 53 is attached to the outer side of the middle part of the conical metal block 52 and the inner side of the shell 55. Four triangular plates 54 are arranged on the outer side of the lower part of the shell 55, and the triangular plates 54 are arranged inside the plastic seat 2. When the shell 55 is subjected to lateral thrust, the shell 55 tilts to one side and causes the triangular plates 54 to press against the plastic seat 2.

[0037] Moreover, the lowest point of the conical metal block 52 and the lowest point of the plastic seat 2 are located at the same horizontal line. The support plate 53 is made of rubber. Under the gravity of the conical metal block 52 , the support plate 53 pulls the shell 55 for elastic buffering.

[0038] In the present invention, the plastic seat 2 is placed on a horizontal road surface. When the shell 55 is subjected to a lateral force, the shell 55 presses against one side of the plastic seat 2 through the triangular plate 54, and one side of the shell 55 generates a pressing force against the ground. At this time, the support plate 53 tilts along with the shell 55 and causes the conical metal block 52 to also generate a pressing force against the ground. Therefore, the lateral force is shared by the conical metal block 52 and the triangular plate 54. Moreover, since the conical metal block 52 is located in the middle of the shell 55, when the shell 55 drives the support plate 53 to tilt, the gravity of the conical metal block 52 causes the shell 55 to press against the ground in the opposite direction to form a reverse blocking force, and reversely blocks the lateral force of the shell 55, thereby enhancing the resistance to external forces and preventing it from being easy to tip over and unstable.

[0039] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the scope of the patent and the content of the specification should still fall within the scope of the present invention.
