Technical Field
[0001] This utility model relates to the field of transportation technology, and more specifically, to a column-type curve warning device. Background Technology
[0002] In modern transportation systems, curves are accident-prone sections of road. When a vehicle enters a curve, the driver has difficulty knowing the traffic conditions on the other side of the curve in advance. Therefore, a pillar-type curve warning device is used to remind the driver that there is a curve ahead and that they need to slow down. This allows the driver to notice the existence of the curve and the road conditions in advance, improving the safety of driving at night.
[0003] There are certain shortcomings in using a column-type curve warning device: Since the angles of curves in real roads vary greatly, including sharp curves and gentle curves, the traditional column-type curve warning device adopts a design with front and back prompts, which is relatively simple and fixed. It does not fully consider the impact of various curve angles on visibility and information reception. When the curve angle changes, the fixed front and back prompt layout of the device cannot adapt flexibly, which greatly reduces the display effect of the warning information. Utility Model Content
[0004] This utility model provides a column-type curve warning device to solve the problem mentioned in the background art that traditional column-type curve warning devices use a fixed front and back warning design, do not consider the impact of different curve angles (such as sharp curves and gentle curves) on visibility and information reception, and cannot flexibly adapt to changes in curve angle, resulting in poor warning information display effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a column-type curve warning device, comprising a support rod and two warning signs disposed above the support rod, wherein a warning display screen is disposed on one side of the warning sign and a monitor is disposed on the top of the warning sign;
[0006] There are two fixing rings, which are symmetrically arranged on the upper and lower sides of the support rod.
[0007] A drive block is fixedly installed on both ends of the rear side wall of the warning sign by bolts, and the two warning signs can rotate at different angles on the fixed ring by the drive block;
[0008] An angle adjustment component, which is mounted on a fixed ring, is used to drive the two warning signs to adjust along the curve angle.
[0009] Preferably, the angle adjustment component includes:
[0010] The adjusting ring has a hollow, curved structure and is fixedly installed on the end of the drive block away from the warning sign. The adjusting ring is slidably connected to the fixed ring.
[0011] A fixed empty ring is symmetrically installed at one end of the two adjusting rings on opposite sides.
[0012] The extrusion rod is slidably connected inside the fixed hollow ring and is used to extrude the fixed ring;
[0013] The lead screw is rotatably connected inside the fixed hollow rings located on the upper and lower sides, and its two ends are threadedly connected to the extrusion rod.
[0014] The rotating rod, which is installed below the lead screw, is used to drive the lead screw to rotate.
[0015] Preferably, the top of the lower fixing ring has a flat plate hole, and the end of the lower extrusion rod near the flat plate hole is provided with a rubber pad.
[0016] Preferably, a fixed seat is installed on the top of the lower drive block, and a spring rod that slides through the inside of the fixed hollow ring is slidably connected to the middle of the fixed seat. The side of the extrusion rod near the spring rod has an insertion port, and the end of the spring rod away from the extrusion rod is rotatably connected to a turntable. An L-shaped hole is opened on the top of the drive block, and a limiting plate that slides through the vertical end of the L-shaped hole is installed below the turntable.
[0017] Preferably, a dial is installed on the plate hole, and pointer rods are installed on opposite sides of the adjustment rings located at the lower left and right ends for indicating on the dial.

[0019] Preferably, an expansion spring is sleeved on the outside of the upper and lower fixing rings, and shock absorbers are installed at the left and right ends of the expansion springs. The shock absorbers are in close contact with the adjusting rings at the left and right ends.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] 1. This invention addresses the problem of poor visibility and information reception of traditional fixed-layout warning devices due to the diverse angles of road curves in reality. By incorporating an angle adjustment component, this device enables flexible adjustment of the warning sign's angle. Specifically, the operator rotates a lever to drive a lead screw, causing the compression rod to move, thereby releasing or applying the compression force on the fixed ring, changing the friction between the adjusting ring and the fixed ring, and allowing the warning sign to rotate around the central axis of the fixed ring. This design allows for precise adjustment of the warning sign to the appropriate angle according to the actual curve angle, greatly improving the display effect of the warning information. Furthermore, the dial and pointer allow the operator to intuitively and accurately know the adjustment angle value when adjusting the warning sign's angle, and quickly adjust the warning sign to a specific angle based on experience or standards, further improving operational efficiency.
[0022] 2. This invention, through the combination of a turntable, a spring rod, a limiting plate, and an L-shaped hole, allows the spring rod to disengage from or insert into the insertion port of the compression rod by rotating the turntable. At the same time, the clever cooperation between the limiting plate and the L-shaped hole enables the unlocking, limiting, and locking operations to be completed simultaneously during the rotation of the turntable, eliminating the need for cumbersome multiple steps and greatly simplifying the process of adjusting the angle of the warning sign.
[0023] 3. This invention, through the combination of expansion springs and shock-absorbing discs, with expansion springs located on the outside of the two fixed rings and shock-absorbing discs at both ends, plays a buffering role during the adjustment of the warning sign. It absorbs collision energy through elastic deformation, reduces impact force, effectively reduces damage to the warning sign caused by collision, protects the structural integrity of the warning sign, and extends the service life of the device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Example 1
[0033] like Figures 1-4 As shown, this utility model provides a column-type curve warning device, including a support rod 1 and two warning signs 12 set above the support rod 1. The setting of two warning signs 12 means that warnings can be issued simultaneously for vehicles approaching from two opposite directions. No matter which direction the vehicle is approaching the curve, the corresponding warning information can be clearly seen, which greatly improves the coverage and effectiveness of the warning device. A warning display screen 13 is set on one side of the warning sign 12. The warning display screen 13 intuitively displays important warning information to the driver, such as the situation of vehicles ahead of the curve, speed limit reminders, and warnings of special weather or road conditions. A monitor 14 is set on the top of the warning sign 12, which can obtain real-time traffic conditions around the curve. It can monitor vehicle speed, traffic flow, vehicle type and other information, providing accurate data support for the warning system and displaying it on the warning display screen 13, thereby reducing the incidence of curve accidents.
[0034] Two fixed rings 15 are provided, symmetrically arranged on the upper and lower sides of the support rod 1; a drive block 16 is fixedly installed on both ends of the rear side wall of the warning sign 12 by bolts, and the two warning signs 12 rotate at different angles on the fixed rings 15 via the drive block 16; an angle adjustment assembly 2 is provided on the fixed rings 15 and is used to drive the two warning signs 12 to adjust along the curve angle. The angle adjustment assembly 2 includes: an adjustment ring 21, which has a hollow curved structure and is fixedly installed on the end of the drive block 16 away from the warning sign 12. The adjustment ring 21 is slidably connected on the fixed ring 15; and a fixed empty ring 22 is symmetrically installed on one end opposite to the two adjustment rings 21, which is used for compression. Rod 23, which is slidably connected inside the fixed hollow ring 22, is used to compress the fixed ring 15. Screw 24 is rotatably connected inside the fixed hollow ring 22 located on the upper and lower sides, and its two ends are threaded to the compression rod 23. It is worth noting that a pair of limiting protrusions are installed on the compression rod 23 so that it can move up and down inside the fixed hollow ring 22 by the action of screw 24. Rotating rod 25 is installed below screw 24 and is used to drive screw 24 to rotate. A straight hole is installed on the outside of rotating rod 25 to increase the friction with the operator's hand. Rotating rod 25 is located below screw 24 so that the operator can adjust rotating rod 25 according to their corresponding height, thereby improving convenience.
[0035] When it is necessary to point the two warning signs 12 in the opposite direction of the curve, the operator rotates the rotating rod 25. The rotation of the rotating rod 25 drives the lead screw 24 to rotate synchronously. Since the lead screw 24 is threadedly connected to the pressing rod 23, the rotation of the lead screw 24 causes the upper and lower pressing rods 23 to move relative to each other and disengage from the fixed ring 15. The operator can then manually push the warning sign 12 according to the actual angle of the curve, causing the adjusting ring 21 to slide on the fixed ring 15. This, in turn, causes the warning sign 12 to rotate around the central axis of the fixed ring 15 to a suitable angle. At this time, the pressing rod 23 no longer exerts pressure on the fixed ring 15, the friction between the adjusting ring 21 and the fixed ring 15 decreases, and the adjusting ring 21 can slide freely on the fixed ring 15. During this process, the two warning signs 12 are independently adjusted in angle through their respective drive blocks 16 and adjusting rings 21. When the warning sign 12 is rotated to the required angle, the rotating rod 25 is rotated again, causing the lead screw 24 to rotate in the opposite direction. The rotation of the lead screw 24 causes the pressing rod 23 to move relative to the fixed ring 15 again, pressing the fixed ring 15. As the pressing force of the pressing rod 23 on the fixed ring 15 gradually increases, the friction between the adjusting ring 21 and the fixed ring 15 also increases, finally fixing the adjusting ring 21 tightly on the fixed ring 15, thereby keeping the warning sign 12 at the set angle position and completing the entire angle adjustment and fixing process to adapt to the forward and reverse direction requirements of the curve, thus creating conditions for the angle adjustment of the warning sign 12.
[0036] like Figure 5As shown, the top of the fixing ring 15 located below has a flat plate hole 26, and the end of the extrusion rod 23 located below near the flat plate hole 26 is provided with a rubber pad.
[0037] The flat plate hole 26 changes the contact method between the fixing ring 15 and the extrusion rod 23, increasing the friction between them. The rubber pad has a rough and elastic surface, and when it comes into contact with the flat plate hole 26, it can fit the slight unevenness of the surface of the flat plate hole 26, increasing the actual contact area.
[0038] Example 2
[0039] like Figures 3-4 As shown, a fixed base 211 is installed on the top of the drive block 16 located below. A spring rod 212 that slides through the fixed hollow ring 22 is slidably connected to the middle of the fixed base 211. A socket is opened on the side of the extrusion rod 23 near the spring rod 212. The socket is round. The end of the spring rod 212 near the socket is set in a conical shape to improve the limiting effect with the socket. A turntable 213 is rotatably connected to the end of the spring rod 212 away from the extrusion rod 23. An L-shaped hole 214 is opened on the top of the drive block 16. A limiting plate 215 that slides through the vertical end of the L-shaped hole 214 is installed below the turntable 213.
[0040] When the angle of the warning sign 12 needs to be changed, rotating the turntable 213 causes the spring insert 212 to disengage from the insertion port of the compression rod 23. At the same time, the limiting plate 215 below the turntable 213 rotates from the vertical end of the L-shaped hole 214 at the top of the drive block 16 to the horizontal end and engages, releasing the restriction on the compression rod 23 so that it can rotate within the fixed empty ring 22, thereby adjusting the angle of the warning sign 12. After the warning sign 12 is adjusted to the appropriate angle, rotating the turntable 213 in the opposite direction causes the limiting plate 215 to rotate from the horizontal end of the L-shaped hole 214 back to the vertical end, and the spring insert 212 is inserted into the compression rod 23 under the action of the spring. The insertion port of rod 23 fixes the angle of the warning sign 12. In addition to the fixing method of the screw 24 driving the compression rod 23 to compress the fixing ring 15, the design of the spring rod 212 inserting into the insertion port of the compression rod 23 provides additional fixing protection. Moreover, through the ingenious cooperation of the turntable 213, the limiting plate 215 and the L-shaped hole 214, the operator only needs to rotate the turntable 213 to simultaneously complete the unlocking and limiting of the spring rod 212, as well as the subsequent locking operation. There is no need for complicated multi-step operation, which greatly simplifies the process of adjusting the angle of the warning sign 12 and improves the operating efficiency.
[0041] like Figure 5 As shown, a dial 27 is mounted on the flat plate hole 26, and a pointer rod 271 is mounted on the opposite side of the adjustment rings 21 located at the lower left and right ends for indicating on the dial 27.
[0042] The dial 27 is marked with clear graduations, and the pointer 271 indicates the corresponding graduations on the dial 27 as the adjustment ring 21 rotates. This allows the operator to intuitively and accurately know the angle value when adjusting the warning sign 12. For example, when facing curves with different curvatures, the staff can adjust the warning sign 12 to a specific angle based on experience or pre-set standards to ensure that the warning information can be displayed to the driver at the best angle, thereby improving the effectiveness of information transmission.
[0043] Example 3
[0044] like Figure 6 As shown, a slide rail 221 is installed at the rear end of the support rod 1. A linkage groove is opened inside the slide rail 221. A lifting rod 222 is rotatably connected in the linkage groove. The top end of the lifting rod 222 passes through the slide rail 221 and is equipped with a rotating disc. A slider 223 is slidably connected to the middle of the slide rail 221. A lifting block that is threadedly connected to the lifting rod 222 is installed on the inner side of the slider 223. A T-shaped plate 224 is installed at the end of the slider 223 away from the support rod 1. The rear ends of the two fixing rings 15 are fixedly connected to the vertical end of the T-shaped plate 224.
[0045] By rotating the rotating disc, the lifting rod 222 is driven to rotate in the linkage groove of the slide rail 221. Since the lifting block is threadedly connected to the lifting rod 222 and the slider 223 slides in the middle of the slide rail 221, when the lifting rod 222 rotates, the lifting block moves up and down along the lifting rod 222 under the action of the thread, thereby driving the slider 223 to slide on the slide rail 221. The T-shaped plate 224 is installed at the end of the slider 223 away from the support rod 1, and the two fixing rings 15 are fixedly connected to the vertical end of the T-shaped plate 224, thus realizing the up and down adjustment of the fixing rings 15. The height of the fixing rings 15 can be easily adjusted to adapt to different usage scenarios or needs, enhancing the flexibility and adaptability of the device in use.
[0046] like Figure 2 As shown, an expansion spring 231 is sleeved on the outside of the upper and lower fixed rings 15. A shock absorber 232 is installed at the left and right ends of the expansion spring 231. The shock absorber 232 is in close contact with the adjusting rings 21 at the left and right ends.
[0047] To prevent the two warning signs 12 from colliding during adjustment, the expansion spring 231 acts as a buffer. Through its own elastic deformation, it absorbs part of the energy generated by the collision, reduces the impact force at the moment of collision, effectively reduces the damage to the warning sign 12 caused by the collision, and protects the structural integrity of the warning sign 12.
[0048] The working principle is as follows: When using a column-type curve warning device, the operator rotates the rotating rod 25, causing the lead screw 24 to rotate. This causes the upper and lower pressing rods 23, which are threadedly connected to the lead screw 24, to move relative to each other and disengage from the fixed ring 15. At this time, the friction between the adjusting ring 21 and the fixed ring 15 decreases, and the warning sign 12 can be manually pushed to allow the adjusting ring 21 to slide on the fixed ring 15, causing the warning sign 12 to rotate around the central axis of the fixed ring 15 to a suitable angle. Then, the rotating rod 25 is rotated again to make the lead screw 24 rotate in the opposite direction. The pressing rods 23 press the fixed ring 15 again, increasing the friction between the adjusting ring 21 and the fixed ring 15, thus fixing the angle of the warning sign 12. The hole 26 and the rubber pad increase the friction between the fixing ring 15 and the extrusion rod 23. Rotating the turntable 213 causes the spring rod 212 to disengage from the insertion port of the extrusion rod 23. At the same time, the limiting plate 215 below the turntable 213 rotates from the vertical end of the L-shaped hole 214 at the top of the drive block 16 to the horizontal end and engages, releasing the restriction on the extrusion rod 23. The angle of the warning sign 12 can be adjusted. After adjusting to the appropriate angle, the turntable 213 is rotated in the opposite direction, and the limiting plate 215 rotates back to the vertical end. The spring rod 212 is inserted into the insertion port of the extrusion rod 23 under the action of the spring, fixing the angle of the warning sign 12. The scale 27 and the pointer rod 271 cooperate to allow the operator to intuitively and accurately know the adjusted angle value.
