Abstract
Description
Technical Field
[0001] This application relates to the technical field of traffic indication devices, and specifically to a traffic sign that automatically resets after being bumped and scratched. Background Art
[0002] Road traffic signs use graphic symbols and text to convey legal information to drivers and pedestrians, and are safety facilities for controlling, warning, and guiding traffic. They play an important role in modern road traffic management.
[0003] In the maintenance operations of national and provincial roads, the linear induction signs at the U-turns in the central median are often collided by large vehicles turning, making U-turns, or violating regulations on over-limit, which affects traffic safety. Most of the anti-collision mechanisms of existing road traffic signs are integrated with the road traffic signs. When the impact force is too large and the anti-collision mechanism is damaged, the road traffic signs need to be replaced synchronously with the anti-collision mechanism, resulting in a waste of usage costs.
[0004] Therefore, this application provides a traffic sign that automatically resets after being bumped and scratched to solve the above problems. Utility Model Content
[0005] This application provides a traffic sign that automatically resets after being bumped and scratched, aiming to solve the problems in the background art that most of the anti-collision mechanisms of existing road traffic signs are integrated with the road traffic signs. When the impact force is too large and the anti-collision mechanism is damaged, the road traffic signs need to be replaced synchronously with the anti-collision mechanism, resulting in a waste of usage costs.
[0006] To achieve the above object, this application provides the following technical solution: A traffic sign that automatically resets after being bumped and scratched, including a gravity reset mechanism for supporting the road sign installed on the road sign post; the gravity reset mechanism includes a base fixedly sleeved on the outer side wall of the road sign post and a reset sleeve movably sleeved on the outer side wall of the road sign post and lapping on the top of the base for fixing the road sign. Two continuously arranged and identically rotating upper inclined plane supports are fixedly installed on the top of the base, and a lower inclined plane support adapted to the upper inclined plane support is fixedly installed at the bottom of the reset sleeve. In this way, when being collided by a vehicle on the side, the reset sleeve will rotate and rise along the slope surface of the upper inclined plane support on the base through the lower inclined plane support. When the vehicle drives away, affected by the gravity of the reset sleeve and the road sign, it will automatically slide down and reset along the slope surface of the upper inclined plane support without additional power, easily achieving the effects of avoiding danger and resetting, and reducing the maintenance cost.
[0007] Preferably, for installing the road sign, two opposed connecting bars are fixedly installed on the back surface of the road sign. Hoop rings fixed by bolts and sleeved on the outer side wall of the reset sleeve are fixedly installed on the outer side walls of the two connecting bars. The hoop rings on the connecting bars can be sleeved downward from the top on the outside of the reset sleeve and then fixed by bolts, which is convenient and fast.
[0008] Preferably, to reduce the friction between the reset sleeve and the road sign post, a ball groove consistent with the rotation direction of the upper inclined plane support is formed on the outer side wall of the road sign post. A number of uniformly arranged balls are movably installed in the ball groove. The inner side wall of the reset sleeve is in contact with the balls, so that when the reset sleeve rotates under force, a smaller contact surface is provided by the balls, making its rotation and reset more smooth, reducing the inner wall loss, and ensuring stable rotation.
[0009] Preferably, to adjust the height of the road sign, the automatic reset device further includes a height adjustment mechanism. The height adjustment mechanism includes two symmetrically arranged limit grooves formed on the outer side wall of the road sign post. A positioning ring fixedly connected to the base is sleeved on the outer side wall of the road sign post at the positions of the two limit grooves. Installation cavities are formed on the outer side wall of the positioning ring at the positions of the two limit grooves. Rotating shafts are fixedly installed on the inner side walls of the two installation cavities. One end of a card extending into the limit groove and the other end extending outside the installation cavity is rotatably installed on each of the two rotating shafts. In the two limit grooves, upward-opening card slots adapted to the cards and uniformly arranged from top to bottom are fixedly installed. By inwardly squeezing the top ends of the two cards, the cards rotate through the rotating shafts and the other ends are separated from the card slots, so that the positioning ring can drive the base fixed thereto to move up and down on the limit grooves. When it moves to a suitable position, the two cards are released, so that their bottom ends extend into the limit grooves and are clamped and fixed with the card slots at the corresponding heights, thereby stabilizing the positioning ring at the required height. The adjustment is convenient and fast to adapt to different road sections.
[0010] Preferably, to ensure that the card can always be stably clamped with the card slot, a spring is fixedly installed between the outer side wall of one end of the card located outside the installation cavity and the outer side wall of the positioning ring. The spring is in a stretched state in its natural state, pressing one end of the card tightly. The card makes the other end always closely adhere to the card slot at the position of the appropriate card slot through the rotating shaft, preventing accidental slippage and having better stability.
[0011] When the reset device is collided by a vehicle on the side, the reset sleeve will rotate and rise along the slope surface of the upper inclined plane support on the base through the lower inclined plane support. When the vehicle drives away, affected by the gravity of the reset sleeve and the road sign, it will automatically slide down and reset along the slope surface of the upper inclined plane support without additional power, easily achieving the effects of avoiding danger and resetting, and reducing the maintenance cost.
[0012] The reset device squeezes the top ends of two cards inward, causing the cards to rotate through the rotating shaft, and the other end to disengage from the card slot, so that the positioning ring can drive the fixed base up and down on the limiting slot. After moving to the appropriate position, release the two cards, so that their bottom ends extend into the limiting slot and engage with the corresponding-height card slots for fixation, thereby stabilizing the positioning ring at the required height. The adjustment is convenient and fast to adapt to different road sections. Description of the Drawings

Detailed Implementation Modes
[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0020] Embodiment 1
[0021] This embodiment provides a traffic signboard that automatically resets after being scraped or bumped, as Figures 1-4As shown in the figure, the reset device includes a gravity reset mechanism 3 for supporting the road sign 2 installed on the road sign pillar 1. The gravity reset mechanism 3 includes a base 31 fixedly sleeved on the outer side wall of the road sign pillar 1 and a reset sleeve 32 movably sleeved on the outer side wall of the road sign pillar 1 and lapped with the top of the base 31 for fixing the road sign 2. Two continuously arranged upper inclined plane supports 33 with the same rotation direction are fixedly installed on the top of the base 31, and a lower inclined plane support 34 adapted to the upper inclined plane support 33 is fixedly installed at the bottom of the reset sleeve 32.
[0022] During use, when being collided by the side of an oncoming vehicle, the reset sleeve 32 will rotate and rise along the slope surface of the upper inclined plane support 33 on the base 31 through the lower inclined plane support 34. When the vehicle drives away, affected by the gravity of the reset sleeve 32 and the road sign 2, it will automatically slide down and reset along the slope surface of the upper inclined plane support 33 without additional power, easily achieving the effects of risk avoidance and reset, and reducing the maintenance cost.
[0023] In some embodiments, two opposed connecting bars 35 are fixedly installed on the back of the road sign 2, and hoop rings 36 fixedly installed on the outer side walls of the two connecting bars 35 and sleeved on the outer side wall of the reset sleeve 32 and fixed by bolts are provided. During use, the hoop rings 36 on the connecting bars 35 are sleeved on the outside of the reset sleeve 32 from the top downwards and then fixed by bolts, which is convenient and fast.
[0024] In some embodiments, a ball groove 37 with the same rotation direction as the upper inclined plane support 33 is opened on the outer side wall of the road sign pillar 1, and a number of uniformly arranged balls 38 are movably installed in the ball groove 37, and the inner side wall of the reset sleeve 32 is in contact with the balls 38. During use, when the reset sleeve 32 rotates under force, the balls 38 provide a smaller contact surface, making its rotation and reset more smooth, reducing the inner wall loss, and ensuring stable rotation.
[0025] Embodiment 2
[0026] Different from Embodiment 1, at different height limits or different road sections, the installation height of the sign is different. For this reason, the automatic reset device further includes a height adjustment mechanism 4. The height adjustment mechanism 4 includes two symmetrically arranged limit grooves 41 opened on the outer side wall of the road sign pillar 1. A positioning ring 42 fixedly connected with the base 31 is sleeved on the outer side wall of the road sign pillar 1 at the positions of the two limit grooves 41. Installation cavities 43 are opened on the outer side wall of the positioning ring 42 at the positions of the two limit grooves 41. Rotating shafts 44 are fixedly installed on the inner side walls of the two installation cavities 43, and cards 45 with one end extending into the limit groove 41 and the other end extending outside the installation cavity 43 are rotatably installed on the two rotating shafts 44. Card slots 46 which are arranged uniformly from top to bottom and adapted to the cards 45 and open upwards are fixedly installed in the two limit grooves 41.
[0027] When in use, by squeezing the top ends of the two cards 45 inward, the cards 45 rotate through the rotating shaft 44, and the other end disengages from the card slot 46, so that the positioning ring 42 can drive the fixed base 31 up and down on the limiting groove 41. When it moves to the appropriate position, release the two cards 45, so that the bottom ends thereof extend into the limiting groove 41 and are engaged and fixed with the card slots 46 at the corresponding height, thereby stabilizing the positioning ring 42 at the required height. The adjustment is convenient and fast to adapt to different road sections.
[0028] In some embodiments, a spring 47 is fixedly installed between the outer side wall of the end of the card 45 located outside the installation cavity 43 and the outer side wall of the positioning ring 42. When in use, the spring 47 is in a stretched state in its natural state, pressing one end of the card 45 tightly. The card 45 makes the other end always closely adhere to the card slot 46 when moving to the appropriate position of the card slot 46 through the rotating shaft 44, preventing accidental slippage and having better stability.
[0029] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
