Utility Model Content

[0005] In order to solve the above problems, the utility model provides a curve prompting structure.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a curve warning structure, including a support column, a frame arranged on the top of the support column and a wide-angle lens arranged in the frame, a base is arranged at the bottom of the support column, a rotating component for facilitating the rotation of the support column is arranged at the bottom of the support column, two frames are arranged and symmetrically distributed about the axis of the support column, a wide-angle lens is configured in each of the frames, and a fixing component for fixing the support column is arranged on the base.

[0007] By adopting the above technical solution, when the wide-angle mirror used for indication is accidentally damaged, the staff must first adjust the fixing component to release the fixing effect on the support column, and then use the rotating component to adjust the steering of the support column so that the spare wide-angle mirror is rotated to the side used for corner vehicle indication, and then fix the support column again through the fixing component, so that the undamaged wide-angle mirror can continue to play the role of indicating vehicles at the intersection, thereby changing the situation where the damaged wide-angle mirror can no longer play the role of indicating vehicles at the intersection during the replacement period.

[0008] Furthermore, the base includes a first mounting plate and a second mounting plate arranged on the bottom surface of the first mounting plate, the first mounting plate is penetrated by a first bolt that is gap-matched with the first mounting plate, the lower end of the first bolt is threadedly connected to the top of the second mounting plate, the rotating assembly includes a rotating seat fixed to the lower end of the support column, the first mounting plate is penetrated by a mounting groove that is matched with the rotating seat, the fixing assembly includes a second bolt that is penetrated by a second bolt that is threadedly connected to the rotating seat, and a rectangular block rotatably connected to the lower end of the second bolt, the top of the second mounting plate is provided with a second groove that is snap-fitted with the rectangular block, and the bottom of the rotating seat is provided with a first groove that is slidably matched with the rectangular block at a position corresponding to the second groove, the second groove is provided with two and is symmetrically arranged about the support column, and the depth of the first groove is greater than or equal to the thickness of the rectangular block.

[0009] By adopting the above technical solution, when the rotating assembly is used to rotate the support column and the support column needs to be fixed, the staff needs to tighten the second bolt on the rotating seat to make the second bolt move vertically upward, and the second bolt drives the rectangular block to move vertically upward. During the movement of the rectangular block, the rectangular block will slip out of the second groove and rise into the first groove. When the rectangular block is completely raised into the first groove, the staff rotates the rotating seat by lifting the second bolt on the top surface of the rotating seat. After the second bolt rotates 180° around the support column, the rectangular block corresponds to the second groove position on the other side. At this time, the staff needs to tighten the second bolt again to make the rectangular block plug into the second groove, and the replacement of the spare wide-angle lens is completed.

[0011] By adopting the above technical solution, the shape of the rotating seat is restricted, the stability of the connection between the rotating seat and the first mounting plate is enhanced, and the rotating seat is prevented from falling off from the mounting groove.

[0012] Furthermore, a first indicator line is arranged at a position on the top of the first mounting plate corresponding to the second groove, and two first indicator lines are arranged symmetrically and collinearly with respect to the support column; a second indicator line is arranged at a position on the top of the rotating seat corresponding to the first groove, and two second indicator lines are arranged symmetrically and collinearly with respect to the support column.

[0013] By adopting the above technical solution, when replacing the spare wide-angle lens, the staff only needs to tighten the second bolt and make the rectangular block enter the first groove from the second groove, and then rotate the rotating seat around the support column through the second bolt until the second indicator line and the first indicator line are collinear again. The position of the rectangular block is in a corresponding state with the position of the second groove on the other side, which reduces the difficulty for the staff to align the adjusted rectangular block with the second groove on the other side, and improves the efficiency of replacing the wide-angle lens.

[0014] Furthermore, the rotating assembly also includes a ball roller arranged between the rotating seat and the second mounting plate, the bottom surface of the rotating seat is provided with an upper arc-shaped groove for rolling cooperation with the ball roller, the top of the second mounting plate is provided with a lower arc-shaped groove for rolling cooperation with the ball roller, the bottom surface of the rotating seat abuts against the top surface of the second mounting plate, and the ball rollers are provided in plurality and are symmetrically distributed about the axis of the support column.

[0015] By adopting the above technical solution, the setting of the ball enables a rolling connection between the rotating seat and the second mounting plate, which makes it easier for the staff to adjust the rotating direction of the rotating seat.

[0016] Furthermore, the first bolt is a hexagon socket countersunk bolt, and a receiving hole for receiving the head of the first bolt is provided on the top of the rotating seat.

[0019] By adopting the above technical solution and setting the third bolt, it is convenient for the staff to disassemble and replace the damaged wide-angle lens later.

[0020] Furthermore, a side cover matching with the frame is arranged in one of the frames.

[0021] By adopting the above technical solution and setting the side cover, the probability of the spare wide-angle lens being unable to be used due to external force or natural factors when not in use is reduced.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In this application, when the wide-angle mirror used for indication is accidentally damaged, the staff first needs to adjust the fixing assembly to release the fixing effect on the support column, and then use the rotating assembly to adjust the support column so that the spare wide-angle mirror is rotated to the side used for corner vehicle indication, and then fix the support column again through the fixing assembly, so that the undamaged wide-angle mirror can continue to play the role of indicating vehicles at the intersection, changing the situation that the damaged wide-angle mirror can no longer play the role of indicating vehicles at the intersection during the replacement period;

In this embodiment, two frames 2 are provided and symmetrically distributed about the axis of the support column 1, and a wide-angle mirror 21 is configured in each frame 2, and the wide-angle mirror 21 on the side away from the corner of the intersection is a spare wide-angle mirror 21.

[0033] The base 3 is arranged at the bottom of the support column 1, and the base 3 includes a first mounting plate 31 and a second mounting plate 32 arranged on the bottom surface of the first mounting plate 31. A first bolt 311 is penetrated through the first mounting plate 31 and is loosely matched with the first mounting plate 31. The lower end of the first bolt 311 is threadedly connected to the top of the second mounting plate 32, and the axis of the base 3 coincides with the axis of the support column 1.

[0034] The first mounting plate 31 is provided with a mounting groove 312 that cooperates with the rotating seat 41. The rotating assembly 4 is provided at the bottom of the support column 1 and is used to facilitate the rotation of the support column 1. The rotating assembly 4 includes a rotating seat 41 and a ball 42. The rotating seat 41 is fixed at the lower end of the support column 1, and the ball 42 is provided between the rotating seat 41 and the second mounting plate 32. Specifically, the bottom surface of the rotating seat 41 is provided with an upper arc groove 413 that rolls with the ball 42, and the top of the second mounting plate 32 is provided with a lower arc groove 322 that slides with the ball 42. The bottom surface of the rotating seat 41 abuts against the top surface of the second mounting plate 32, and the ball 42 is provided in plurality and symmetrically distributed about the axis of the support column 1. The provision of the ball 42 enables the rotating seat 41 to be rollingly connected with the second mounting plate 32, so that the staff can save more effort when adjusting the rotation direction of the rotating seat 41.

[0035] The fixing assembly 5 is arranged on the base 3 and is used to fix the support column 1. The fixing assembly 5 includes a second bolt 51 and a rectangular block 52. The second bolt 51 is arranged through the rotating seat 41 and is threadedly connected to the rotating seat 41. The rectangular block 52 is rotatably mounted at the lower end of the second bolt 51. In this embodiment, a second groove 321 that is snap-fitted with the rectangular block 52 is arranged on the top of the second mounting plate 32, and a first groove 411 that is slidably matched with the rectangular block 52 is arranged at a position corresponding to the second groove 321 at the bottom of the rotating seat 41. Two second grooves 321 are provided and are symmetrically arranged about the support column 1, and the depth of the first groove 411 is greater than or equal to the thickness of the rectangular block 52.

[0036] When the wide-angle mirror 21 used for indication is accidentally damaged, the staff must first adjust the fixing component 5 to release the fixing effect on the support column 1, and then use the rotating component 4 to adjust the steering of the support column 1 so that the spare wide-angle mirror 21 is rotated to the side used for corner vehicle indication, and then fix the support column 1 again through the fixing component 5, so that the undamaged wide-angle mirror 21 continues to play the role of indicating vehicles at the intersection, thereby changing the situation where the damaged wide-angle mirror 21 can no longer play the role of indicating vehicles at the intersection during the replacement period.

[0037] When using the rotating assembly 4 to rotate the support column 1 and the support column 1 needs to be fixed, the staff needs to tighten the second bolt 51 on the rotating seat 41 to make the second bolt 51 move vertically upward, and the second bolt 51 drives the rectangular block 52 to move vertically upward. During the movement, the rectangular block 52 will slip out of the second groove 321 and rise into the first groove 411. When the rectangular block 52 is completely raised into the first groove 411, the staff rotates the rotating seat 41 by lifting the second bolt 51 on the top surface of the rotating seat 41. After the second bolt 51 rotates 180° around the support column 1, the rectangular block 52 corresponds to the second groove 321 on the other side. At this time, the staff needs to tighten the second bolt 51 again to make the rectangular block 52 plug into the second groove 321, and the replacement of the spare wide-angle lens 21 is completed.

[0038] In order to prevent the rotating seat 41 from falling off from the mounting groove 312, the rotating seat 41 is in a truncated cone shape, and the upper surface area of ​​the rotating seat 41 is smaller than the bottom area of ​​the rotating seat 41. The restriction on the shape of the rotating seat 41 enhances the stability of the connection between the rotating seat 41 and the first mounting plate 31.

[0039] In order to improve the efficiency of replacing the wide-angle mirror 21, a first indicator line 313 is arranged at a position corresponding to the second groove 321 on the top of the first mounting plate 31, and two first indicator lines 313 are arranged symmetrically and collinearly with respect to the support column 1. A second indicator line 412 is arranged at a position corresponding to the first groove 411 on the top of the rotating seat 41, and two second indicator lines 412 are arranged symmetrically and collinearly with respect to the support column 1. When replacing the spare wide-angle mirror 21, the staff only needs to tighten the second bolt 51 and make the rectangular block 52 enter the first groove 411 from the second groove 321, and then rotate the rotating seat 41 around the support column 1 by the second bolt 51 until the second indicator line 412 is collinear with the first indicator line 313 again, and the position of the rectangular block 52 is in a corresponding state with the position of the second groove 321 on the other side, thereby reducing the difficulty for the staff to align the adjusted rectangular block 52 with the second groove 321 on the other side.

[0040] In order to improve the aesthetics, the first bolt 311 is a hexagon socket countersunk bolt, and a receiving hole 414 for receiving the head of the first bolt 311 is provided on the top of the rotating seat 41 .

[0041] In order to facilitate the staff to subsequently disassemble and replace the damaged wide-angle lens 21, a cross bar 11 is fixed to the side wall of the support column 1, and a support plate 22 is fixed to the side wall of the lens frame 2 close to the support column 1. A third bolt 23 is provided through the support plate 22 and is clearance-matched with the support plate 22. The end of the third bolt 23 is threadedly connected to the cross bar 11.

[0042] In order to reduce the probability that the spare wide-angle lens 21 cannot be used due to external forces or natural factors when not in use, a side cover 24 that cooperates with the lens frame 2 is provided in one of the lens frames 2 .

[0043] The use principle of a curve prompt structure in the present embodiment is as follows: when the wide-angle mirror 21 used for indication is accidentally damaged, the staff needs to screw the second bolt 51 on the rotating seat 41 to make the second bolt 51 move vertically upward, and the second bolt 51 drives the rectangular block 52 to move vertically upward. During the movement, the rectangular block 52 will escape from the second groove 321 and rise into the first groove 411. When the rectangular block 52 is completely raised into the first groove 411, the staff rotates the rotating seat 41 by lifting the second bolt 51 on the top surface of the rotating seat 41. After the second bolt 51 rotates 180° around the support column 1, the rectangular block 52 corresponds to the position of the second groove 321 on the other side. At this time, the staff needs to screw the second bolt 51 again to make the rectangular block 52 plug into the second groove 321, completing the replacement of the spare wide-angle mirror 21, so that the spare wide-angle mirror 21 continues to play the role of reminding vehicles at the intersection, and changes the situation that the damaged wide-angle mirror 21 cannot continue to play the role of reminding vehicles at the intersection during the replacement period.
