Description

Technical Field

[0001] This invention belongs to the field of traffic technology, and in particular relates to a traffic sign pole structure that tilts in a specific direction after an impact. Background Technology

[0002] Traffic sign poles are pillars used to support and install traffic signs in highway traffic facilities. They are usually set up on both sides of the driving lane to provide drivers with necessary traffic guidance and road condition warnings to ensure driving safety. Since traffic sign poles are set in the green belts along the roadside, they are very easy to hit in the event of a vehicle accident, which can cause the sign poles to tip over. In addition, since the signs on the poles are usually large, they can easily affect traffic after falling onto the road. This paper proposes a directional tipping structure that can avoid traffic disruption. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a traffic sign pole structure that tilts in a specific direction upon impact, thus solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a traffic sign pole structure that tilts directionally upon impact, comprising a support rod and a transmission assembly. The support rod is coaxially fixedly connected to the upper surface of a base, the base being fixed within a roadside green belt. A connecting cylinder is coaxially rotatably mounted on the upper outer wall of the support rod. An indicator sign is horizontally fixedly connected to the side of the connecting cylinder, and when the base is in its initial position, its side is above the road surface. Multiple connecting rods are vertically fixedly connected to the lower end face of the connecting cylinder, and the connecting rods surround the support rod. The lower end face of the connecting rod is vertically fixedly connected to the upper surface of a sleeve. The sleeve is coaxially rotatably mounted on the outer wall of the support rod, and a threaded ring is fixedly connected to the outer wall of the sleeve. A threaded cylinder is coaxially mounted below the threaded ring, and the threaded cylinder is threadedly connected to the threaded ring during sliding. The threaded cylinder is coaxially slidably mounted on the outer wall of the support rod. The transmission assembly is used to cause the threaded cylinder to move linearly on the support rod during the tilting process.

[0005] A further technical solution: The transmission assembly includes a vertical rod and a support block. The vertical rod is vertically mounted on the side wall of the base, and the upper end of the vertical rod is hinged to the threaded cylinder. The support block is hinged to the lower end of the vertical rod, and in the initial position, the support block is close to the outer wall of the base and fits against the outer wall of the base. The lower end face of the support block has multiple sharp protrusions for piercing the ground. When the sharp protrusions pierce the ground, the threaded cylinder can perform linear movement.

[0006] A further technical solution: The base is provided with an adjustment component for rotating the upright when it is tilted in a directional manner. The adjustment component includes a through groove and a positioning component. The through groove is vertically arranged on the outer wall of the base and extends to its inner wall. The through groove is located on the side of the upright. A push rod is rotatably arranged in the through groove, and the upper end of the push rod contacts the side of the upright closer to the base. The positioning component is used to make the push rod push the upright to rotate.

[0007] A further technical solution: The positioning component includes a pulley, which is rotatably disposed at the lower end of the top rod and is attached to the upper surface of the slide plate. The slide plate is vertically slidably disposed in the base. The slide plate is threadedly connected to a lead screw, and the lower end of the lead screw is rotatably connected to the inner bottom surface of the base. The upper end of the lead screw extends through the support rod.

[0008] A further technical solution: The support rod is provided with a traction assembly for tilting the base in an oriented manner. The traction assembly includes a top cover. The upper end of the lead screw is rotatably disposed at the axis of the lower end face of the top cover, and the top cover is rotatably disposed on the upper end face of the support rod. A steel wire rope is fixedly connected to the side of the top cover. The other end of the steel wire rope is fixedly connected to the winding drum, and the two ends of the steel wire rope are not in the same vertical plane.

[0009] A further technical solution: The winding drum is horizontally arranged on the frame, and the winding drum is rotatably connected to the frame. The frame is slidably arranged in the mounting base, and a slot is slidably arranged on the upper surface of the mounting base. The wire rope passes through the through hole on the surface of the slot and emerges from the slot. The slot is located above the winding drum.

[0010] A further technical solution: An electric push rod is horizontally arranged on the side of the frame, and the output shaft of the electric push rod is fixedly connected to the frame, and the electric push rod is fixedly connected to the mounting base.

[0011] Beneficial effects This invention provides a traffic sign pole structure that tilts in a specific direction upon impact, which has the following advantages compared to the prior art: 1. During the tilting process of the base, the support block hinged at the lower end of the upright can penetrate into the ground. Therefore, the threaded cylinder will gradually come into contact with the threaded ring under the action of the upright. At this time, the sleeve and the sign will rotate synchronously through the connecting rod fixedly connected between them. That is, this application uses the weight of the base itself to make the sign rotate, which can effectively increase the stability of the sign during daily use. At this time, the two sides of the sign will rotate from the state above the road surface to the state above the green belt where the base is located. That is, at this time, the entire sign is not on the road surface, thus effectively avoiding tilting on the road surface and affecting traffic. 2. During the process of changing the tilting direction of the base by pulling the assembly, the lead screw can start to rotate, the slide can start to rise at a constant speed, and the lower end of the top rod can start to roll on the upper surface of the slide through the pulley rotatably connected to it, thereby causing the top rod to start to rotate with its connection with the through groove as the fulcrum, thereby adjusting the upright to an inclined state so that the support block can be inserted into the ground during the tilting process of the base. 3. When the support pole begins to tip over upon impact, the winding drum gradually winds the wire rope around it, tautening it from a loose state. Once taut, the wire rope pulls the base towards its location, causing the sign to rotate and insert its side into the slot. Because the wire rope remains taut, the sign is effectively prevented from tipping over, ensuring that both the base and the sign remain within the green belt to avoid obstructing traffic.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1-6 According to one embodiment of the present invention, a traffic sign pole structure that tilts directionally upon impact includes a support rod 201 and a transmission assembly. The support rod 201 is coaxially fixedly connected to the upper surface of a base 101. The base 101 is fixed within a roadside green belt. A connecting cylinder 203 is coaxially rotatably mounted on the upper outer wall of the support rod 201. An indicator sign 202 is horizontally fixedly connected to the side of the connecting cylinder 203. When the base 101 is in its initial position, its side is above the road surface, and the lower end face of the connecting cylinder 203 is vertically fixed. Multiple connecting rods 204 are connected, and the connecting rods 204 surround the support rod 201. The lower end face of the connecting rod 204 is vertically fixed to the upper surface of the sleeve 205. The sleeve 205 is coaxially rotatably disposed on the outer wall of the support rod 201, and a threaded ring 207 is fixedly connected to the outer wall of the sleeve 205. A threaded cylinder 208 is coaxially disposed below the threaded ring 207, and the threaded cylinder 208 is threadedly connected to the threaded ring 207 during sliding. The threaded cylinder 208 is coaxially slidably disposed on the outer wall of the support rod 201. The transmission assembly is used to enable the threaded cylinder 208 to move linearly on the support rod 201 during the tilting process.

[0022] Specifically, the transmission assembly includes a vertical rod 209 and a support block 301. The vertical rod 209 is vertically mounted on the side wall of the base 101, and the upper end of the vertical rod 209 is hinged to the threaded cylinder 208. The support block 301 is hinged to the lower end of the vertical rod 209, and in the initial position, the support block 301 is close to the outer wall of the base 101 and fits against the outer wall of the base 101. The lower end face of the support block 301 has multiple sharp protrusions for piercing the ground. When the sharp protrusions pierce the ground, the threaded cylinder 208 can perform linear movement.

[0023] In the above embodiment, when the base 101 tilts in a predetermined direction, since the upright 209 is tilted relative to the base 101, the support block 301 hinged at the lower end of the upright 209 can penetrate the ground during the tilting process. At this time, due to the large weight of the base 101 and the support rod 201, under the weight of the base 101 and the support rod 201, and with the lower end of the upright 209 relatively fixed, the threaded cylinder 208 begins to move linearly along the axial direction of the base 101 on its surface under the action of the upright 209. As the tilt angle of the base 101 increases, the sliding distance of the threaded cylinder 208 on the base 101 increases synchronously, causing the threaded cylinder 208 to gradually contact the threaded ring 207. Furthermore, due to the contact between the threaded cylinder 208 and the threaded ring 207... The threaded ring 207 engages with the base 101, allowing it to rotate circumferentially and drive the sleeve 205 fixedly connected to its top to rotate synchronously. At this time, the sleeve 205 and the sign 202 rotate synchronously through the connecting rod 204 fixedly connected between them. That is, this application uses the weight of the base 101 itself to make the sign 202 rotate, which can effectively increase the stability of the sign 202 during daily use. When the sign 202 rotates 90°, the threaded sleeve 208 disengages from the threaded ring 207, thereby stopping the sign 202 from rotating. At this time, the two sides of the sign 202 are rotated from being above the road surface to being above the green belt where the base 101 is located. Thus, the entire sign 202 is no longer on the road surface, effectively preventing it from tipping over and affecting traffic.

[0024] Specifically, the base 101 is provided with an adjustment assembly for rotating the upright 209 when it is tilted in a directional manner. The adjustment assembly includes a through groove 302 and a positioning assembly. The through groove 302 is vertically disposed on the outer wall of the base 101 and extends through to its inner wall. The through groove 302 is located on the side of the upright 209. A top rod 303 is rotatably disposed in the through groove 302. The upper end of the top rod 303 contacts the side of the upright 209 that is close to the base 101. The positioning component is used to make the top rod 303 push the upright rod 209 to rotate.

[0025] Specifically, the positioning component includes a pulley 304, which is rotatably disposed at the lower end of the top rod 303 and is attached to the upper surface of the sliding plate 305. The sliding plate 305 is vertically slidably disposed within the base 101. The sliding plate 305 is threadedly connected to a lead screw 306, and the lower end of the lead screw 306 is rotatably connected to the inner bottom surface of the base 101. The upper end of the lead screw 306 extends through the support rod 201.

[0026] In the above embodiment, during the process of changing the tilting direction of the base 101 by the pulling assembly, the lead screw 306 can start to rotate. At this time, the slide 305 threadedly connected to it begins to move linearly within the base 101. That is, the slide 305 begins to rise at a constant speed. During this process, since the top rod 303 is rotatably set in the through groove 302 and is in an inclined state at the initial position, when the slide 305 rises, the lower end of the top rod 303 can start to roll on the upper surface of the slide 305 through the pulley 304 rotatably connected to it. This causes the top rod 303 to start to rotate with its connection with the through groove 302 as the fulcrum. That is, at this time, the upper end of the top rod 303 moves further toward the upright 209 and drives the upright 209 to start to rotate upward with its connection with the threaded cylinder 208 as the fulcrum, thereby adjusting it to an inclined state so that the support block 301 can be inserted into the ground during the tilting process of the base 101.

[0027] Specifically, the support rod 201 is provided with a pulling assembly for tilting the base 101 in an oriented manner. The pulling assembly includes a top cover 307. The upper end of the lead screw 306 is rotatably disposed at the axis of the lower end face of the top cover 307, and the top cover 307 is rotatably disposed on the upper end face of the support rod 201. A steel wire rope 308 is fixedly connected to the side of the top cover 307. The other end of the steel wire rope 308 is fixedly connected to the winding drum 309, and the two ends of the steel wire rope 308 are not in the same vertical plane.

[0028] Specifically, the winding drum 309 is horizontally arranged on the frame 401 and is rotatably connected to the frame 401. The frame 401 is slidably arranged in the mounting base 403, and a slot 404 is horizontally slidably arranged on the upper surface of the mounting base 403. The wire rope 308 passes through the through hole on the surface of the slot 404 and the slot 404 is located above the winding drum 309.

[0029] Specifically, an electric push rod 405 is horizontally arranged on the side of the frame 401, and the output shaft of the electric push rod 405 is fixedly connected to the frame 401, and the electric push rod 405 is fixedly connected to the mounting base 403.

[0030] In the above embodiment, when the support rod 201 begins to tilt upon impact, its tilt sensor detects that it is tilted, causing the motor 402 and electric push rod 405 to start. The output shaft of the electric push rod 405 then drives the frame 401 to move horizontally linearly away from the base 101, causing the winding drum 309 mounted on it to move synchronously away from the base 101, thus pulling the base 101 to tilt. That is, when the motor 402 starts to rotate, the winding drum 309, which is fixedly connected to its output shaft, starts to rotate synchronously. Since one end of the wire rope 308 is fixedly connected to the winding drum 309, the winding drum 309 can gradually wind the wire rope 308 onto it. That is, the wire rope 308 gradually tightens from a relatively loose state. When the wire rope 308 is tightened, it can pull the base 101 to tilt in its direction. Since the mounting base 403 is fixed in the green belt, the sign 2... The sign 202 and base 101 can tilt into the green belt, thus avoiding accidental injury due to uncontrollable tilting direction. Since the two ends of the steel wire rope 308 are in the same vertical plane at the initial position, after the steel wire rope 308 is taut, the two ends can be in the same plane. During this process, the steel wire rope 308 can pull the top cover 307 to rotate synchronously, thereby adjusting the pole 209 to an inclined state, and then rotating the sign 202 by 90°. During the sliding of the winding drum 309, it can drive the slot 404 above it to move linearly, thereby moving the slot 404 to the tilting position of the sign 202. After the sign 202 rotates 90°, its side is inserted into the slot 404. Since the steel wire rope 308 is still taut at this time, it can effectively prevent the sign 202 from tilting, so that the base 101 and the sign 202 are both in the green belt, thus avoiding obstruction of traffic.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0032] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0033] (1) Detachable connection: Components are fixed together using screws, splines, wedges, etc. This type of connection allows for disassembly during maintenance without damaging the parts. However, the specifications of the connectors used must be correct. (Such as the length of bolts, keys, and wedges), and tighten them properly.

[0034] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, during connection, [the following should be noted]: Pay attention to process quality, technical testing, and remedial measures (such as correction, polishing, etc.).

[0035] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0036] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.
