[0034] In view of the shortcomings of the existing methods, this application proposes a louver-type bridge and culvert sign to solve the technical problems of the existing technology such as insufficient reliability, easy damage and falling off, and potential safety hazards.

[0035] The present application embodiment provides a shutter type bridge culvert sign, such as Figure 1~Figure 3 As shown, Figure 1 This is a structural schematic diagram of a louvered bridge culvert sign in an embodiment of the present application; Figure 2 for Figure 1 A schematic diagram of the structure of the mounting frame shown; Figure 3 for Figure 1 A schematic cross-sectional structure diagram of the buffer assembly is shown.

[0040] Louver plates 41, a plurality of louver plates 41 are fixedly mounted on the inner side surface of the frame 4;

[0041] A warning sign 42 is provided on a side of the louver 41 facing away from the mounting frame 1 .

[0042] The embodiment of the present application is to install the louver 41 by designing the mounting frame 1, the buffer assembly 2 and the frame 4. When encountering strong winds, the strong wind blows onto the frame 4, and the louver 41 can guide the wind so that the wind passes through the gaps between the louver 41, thereby reducing the area in contact with the wind; at the same time, if the wind is too strong, the frame 4 will push the extension rod 25 to move, so that one end of the extension rod 25 pushes the spring 24, thereby playing a buffering role, avoiding damage to the bridge culvert sign due to strong wind, and increasing the service life of the bridge culvert sign.

[0043] In some embodiments of the present application, the buffer assembly 2 also includes a limit block 26, and the mounting rod 21 also has a limit groove 23, and the limit groove 23 is opened on the outer side of the sliding cavity 22 extending radially, and the limit block 26 is fixedly connected to the end of the extension rod 25 toward the mounting frame 1 and is slidably connected to the inner side surface of the limit groove 23.

[0044] In this embodiment, the slide cavity 22 is opened inside the mounting rod 21. The limiting groove 23 can be a plurality of strip grooves, which are respectively opened at the top and bottom of the inner side of the slide cavity 22, and the limiting block 26 is slidably connected to the inner side of the limiting groove 23, and the movement path of the limiting block 26 is parallel to the axial direction of the slide cavity 22. The contour of the limiting block 26 is a cube, and the limiting block 26 is respectively fixedly installed at the top and bottom of one end of the extension rod 25 facing the mounting frame 1.

[0045] The limiting groove 23 can also be an arc groove or an annular groove, which is opened on the periphery of the sliding cavity 22. The contour of the limiting block 26 is also correspondingly arc-shaped, and is fixedly installed with the end of the extension rod 25 facing the mounting frame 1. The top and bottom here are both Figure 3 Give examples of posture.

[0046] In some embodiments of the present application, a mounting screw 43 is further included. The end of the extension rod 25 facing away from the mounting frame 1 has a threaded hole 27 , and the mounting screw 43 passes through the frame 4 and is connected to the inner side of the threaded hole 27 .

[0047] In this embodiment, a plurality of mounting screws 43 are distributed around the frame 4 on a side facing the mounting bracket 1 , and one end of each mounting screw 43 is threadedly connected to the inner side surface of the corresponding threaded hole 27 .

[0048] In some embodiments of the present application, a first reinforcing rod 12 is further included. The mounting frame 1 includes a plurality of interconnected rods, and two ends of the first reinforcing rod 12 are respectively connected to two adjacent or oppositely arranged rods.

[0049] In this embodiment, the profile of the mounting frame 1 is a rectangular structure formed by four rods that are opposite to each other. Optionally, the two ends of the first reinforcing rod 12 are respectively connected to two parallel rods, and the extension direction of the first reinforcing rod 12 and the extension direction of any rod are interlaced. The first reinforcing rod 12 can improve the bearing capacity of the mounting frame 1, increase the stability of the mounting frame 1, reduce the deformation of the mounting frame 1, and disperse the stress on the mounting frame 1.

[0050] In some embodiments of the present application, a second reinforcing rod 3 is further included, and two ends of the second reinforcing rod 3 are respectively connected to the outer side surface of the mounting rod 21 and the side surface of the mounting frame 1 facing the frame 4.

[0051] In this embodiment, a triangle is formed between the second reinforcing rod 3 and the mounting rod 21 and the rod of the mounting frame 1. The second reinforcing rod 3 can improve the bearing capacity of the buffer component 2, increase the stability of the buffer component 2, reduce the deformation of the buffer component 2, and disperse the stress on the buffer component 2.

[0052] In some embodiments of the present application, a damping rod is further included, which is located on the inner side of the spring 24, and both ends of the damping rod are respectively connected to one end of the extension rod 25 and the inner side surface of the sliding cavity 22, and the mounting rod 21, the sliding cavity 22 and the spring 24 are coaxially arranged.

[0053] In this embodiment, the damping rod is used for shock absorption and vibration reduction, which can improve the shock absorption performance of the buffer assembly 2, extend the life of the buffer assembly 2, especially the life of the spring 24, and improve the safety performance.

[0054] In some embodiments of the present application, there is a gap between any two adjacent louver plates 41 , and the cross-sectional profile of a single louver plate 41 is a triangle.

[0055] In this embodiment, the side of the louver 41 facing away from the mounting frame 1 is an inclined surface, which can guide the wind when blown by the wind and reduce the force-bearing area.

[0056] In some embodiments of the present application, the warning mark 42 is adhesively connected to the louver 41 , or the warning mark 42 is sprayed on the surface of the louver 41 .

[0057] In this embodiment, the warning sign 42 can be pasted on the plurality of louvers 41 by using a sticker, or can be directly sprayed on the louvers 41 by using paint.

[0058] When using, the user first installs the mounting frame 1 on the side of the bridge body, then places the frame 4 on one end of the extension rod 25, and then passes the mounting screw 43 through the inside of the frame 4, and makes one end of the mounting screw 43 threadedly connected to the inner side of the threaded hole 27, so as to install the frame 4;

[0059] During subsequent use, when encountering strong winds and blowing onto the frame 4, the wind will be guided by the louver plates 41, so that the wind will blow from both sides of the louver plates 41 through the front to the back of the frame 4, and when the wind is strong, the frame 4 will push the extension rod 25 to move, so that one end of the extension rod 25 pushes the spring 24, thereby playing a buffering role.

[0060] By cooperating with each other through the structures such as the mounting frame 1, the buffer assembly 2, the frame 4, the louver 41 and the warning sign 42, when encountering strong winds, the louver 41 can guide the wind so that the wind passes through the gaps between the louver 41, reducing the area in contact with the wind, thereby avoiding damage to the bridge culvert sign due to strong winds and increasing the service life of the bridge culvert sign.

[0061] like Figure 4 and Figure 5 As shown, Figure 4 This is a structural schematic diagram of another shutter-type bridge culvert sign in an embodiment of the present application; Figure 5 for Figure 4 Schematic diagram of the side structure of the mounting plate shown.

[0062] In some embodiments of the present application, a mounting plate 5, a side plate 52, a threaded rod 56, a clamping plate 53 and a threaded sleeve 55 are further included. The mounting plate 5 is located on the side of the mounting frame 1 facing away from the frame 4. The two side plates 52 are relatively arranged on the sides of the mounting plate 5. The threaded rod 56 passes through the two side plates 52 and is slidably connected to the side plates 52. The two clamping plates 53 are respectively fixedly connected to the two ends of the threaded rod 56. The threaded sleeve 55 is located between the two side plates 52 and is threadedly connected to the outer side of the threaded rod 56. The frame 4 is hoisted on the clamping plate 53.

[0063] In some embodiments of the present application, one side of the clamping plate 53 is in contact with one side of the mounting plate 5 .

[0064] In this embodiment, mounting plates 5 are provided at both ends of the other side of the mounting frame 1, and second mounting holes 51 are opened inside both ends of the mounting plates 5. Side plates 52 are fixedly installed at both ends of one side of the mounting plate 5, and threaded rods 56 are slidably connected inside the two side plates 52. Clamping plates 53 are fixedly installed at one end of the two threaded rods 56, and third mounting holes 54 are opened inside the two clamping plates 53. Threaded sleeves 55 are threadedly connected to the outer sides of the two threaded rods 56.

[0065] The clamping plate 53 includes at least one main plate and two side plates, the main plate is connected to the threaded rod 56, the first side plate and the second side plate are respectively connected to the two ends of the main plate, but the first side plate and the second side plate extend in opposite directions. Optionally, the first side plate is located on the side of the main plate facing the mounting plate 5, the first side plate extends toward the threaded sleeve 55, the second side plate is located on the side of the main plate facing away from the mounting plate 5, the second side plate extends away from the threaded sleeve 55, and the first side plate is attached to one side of the mounting plate 5.

[0066] When in use, when the mounting frame 1 needs to be installed, the user first places the two mounting plates 5 at the position where the mounting frame 1 needs to be installed, and then the user passes the screw through the inside of the second mounting hole 51 on the mounting plate 5 and into the inside of the bridge body to install the mounting plate 5. Then the user hoists the mounting frame 1 to the top of the clamping plate 53, and presses the top of the mounting frame 1 against the inside of the clamping plate 53 set at the top. Then the user rotates the threaded sleeve 55 so that the threaded sleeve 55 is threadedly connected to the outer side surfaces of the two threaded rods 56, so that the two threaded rods 56 respectively push the clamping plate 53 set at the top and the clamping plate 53 set at the bottom, so that the two clamping plates 53 respectively clamp the top of the mounting frame 1, and then the screw is passed through the third mounting hole 54 and the first mounting hole 11 to install the mounting frame 1.

[0067] The mounting plate 5 is installed first, and then the mounting frame 1 is hoisted onto the clamping plate 53. The mounting frame 1 is then limited and fixed by moving the clamping plate 53. This avoids directly installing the mounting frame 1 and the bridge body. Since the mounting frame 1 is large in size and it is inconvenient to adjust the position and limit the mounting frame 1, it is convenient for users to install the mounting frame 1.

[0068] Compared with the prior art, the application of the embodiments of the present application can at least achieve the following beneficial effects: the embodiments of the present application install the louver 41 by designing the mounting frame 1, the buffer assembly 2 and the frame 4. When encountering strong winds, the strong winds blow onto the frame 4, and the louver 41 can guide the wind so that the wind passes through the gaps between the louver 41, thereby reducing the area in contact with the wind; at the same time, if the wind is too strong, the frame 4 will push the extension rod 25 to move, so that one end of the extension rod 25 pushes the spring 24, thereby playing a buffering role, avoiding damage to the bridge culvert sign due to strong wind, and increasing the service life of the bridge culvert sign.
