Description

Technical Field

[0001] This utility model relates to the field of warning post technology, and in particular to a retractable and adjustable road warning post. Background Technology

[0002] Warning posts are an important traffic facility used to remind and guide drivers to prevent road traffic accidents. They are mainly placed in front of the entrance section of intersections on main and secondary roads without traffic lights, as well as on both sides of smaller intersections along highways. They are used to remind drivers of the existence of intersections, and by providing clear warning and guidance information, they help regulate traffic order, prevent traffic accidents, and provide a solid guarantee for the safety and smooth flow of road traffic.

[0003] A search revealed that Chinese patent CN213056883U discloses a retractable and adjustable road warning post. Addressing the issue that current road warning posts are large and inconvenient to store in the trunk, and that reflective strips alone are insufficient for nighttime illumination (potentially leading to accidents), this new design addresses this problem. Pulling the ring moves the locking block within the solid block to the corresponding small through-hole slot. The elasticity of the telescopic spring then secures the locking block within the slot, improving the device's practicality.

[0004] The aforementioned warning posts are adjusted in height by using a telescopic spring to push the locking block. This can easily lead to insufficient tightness after adjustment, and the posts may retract under accidental external force. In addition, warning posts in the existing technology are usually at a fixed height. When using different sizes of warning posts for different roads in different regions, it is necessary to customize and purchase different sizes of warning posts, which reduces the versatility of the warning posts and increases the purchase cost. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a retractable and adjustable road warning post.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a retractable and adjustable road warning post, comprising a first post body, a reflective sticker on the outside of the first post body, a second post body slidably connected to the outside of the first post body, a reflective top sticker on the upper surface of the second post body, and a telescopic component inside the second post body;

[0007] The telescopic component includes a connecting column, which is fixedly connected to the inside of the second pile body. The connecting column has a threaded groove inside, and the first pile body has an adjustment groove inside. A shaft is rotatably connected inside the adjustment groove.

[0008] As a further description of the above technical solution:

[0009] One end of the shaft is fixedly connected to a screw rod, which is threaded into the inside of the threaded groove. A driven bevel gear is fixedly connected to the outside of the shaft, and a driving bevel gear is rotatably connected to the inner wall of the adjusting groove. The driving bevel gear and the driven bevel gear are meshed together.

[0010] As a further description of the above technical solution:

[0011] A motor is fixedly installed on one side of the first pile body, the middle part of the active bevel gear is fixedly connected to the output end of the motor, and a limit block is fixedly connected to one end of the connecting column. The limit block is slidably connected inside the adjustment groove.

[0012] As a further description of the above technical solution:

[0013] A buffer assembly is provided on the outside of the second pile body. The buffer assembly includes multiple grooves, which are formed on the outside of the second pile body.

[0014] As a further description of the above technical solution:

[0015] The groove is fixedly connected to a plurality of fixed tubes, and a first limiting ring is fixedly connected to one end of each fixed tube.

[0016] As a further description of the above technical solution:

[0017] The fixed tube is internally slidably connected to a second limiting ring, and the second limiting ring is internally fixedly connected to a sliding tube.

[0018] As a further description of the above technical solution:

[0019] A buffer spring is fixedly connected inside the sliding tube, and one end of a plurality of buffer springs is fixedly connected inside the groove. A buffer shell is fixedly connected to one end of a plurality of sliding tubes, and a reflective strip is provided on one side of the buffer shell.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model, through the setting of the telescopic component, adds a function to the warning post that allows for flexible adjustment of the height of the warning post by sliding the second post body outside the first post body, according to the road environment and the required warning height. Furthermore, the threaded groove, screw, and connecting column facilitate the improvement of the tightness of the warning post after the height is adjusted. Unless the motor is deliberately rotated, the second post body will not retract even if the upper surface of the second post body is accidentally touched, thus improving the stability after the height is adjusted.

[0022] 2. By incorporating a buffer component, this utility model enhances the ability of the warning post to absorb external impact forces. Utilizing the elasticity of the buffer shell and buffer spring, it helps to reduce the impact force when pedestrians accidentally collide with the second post, thus protecting them. At the same time, it also extends the service life of the second post while mitigating the impact force. Attached Figure Description

[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] As attached Figure 1-6As shown, one embodiment of this utility model is provided: a retractable and adjustable road warning post, including a first post body 1, a reflective sticker 2 provided on the outside of the first post body 1, a second post body 3 slidably connected to the outside of the first post body 1, a reflective top sticker 4 provided on the upper surface of the second post body 3, and a telescopic component provided inside the second post body 3.

[0033] The telescopic assembly includes a connecting post 5, which is fixedly connected to the inside of the second pile body 3. The connecting post 5 has a threaded groove 6 inside, and the first pile body 1 has an adjusting groove 7 inside. The adjusting groove 7 is rotatably connected to a shaft 8. The threaded groove 6 matches the texture of the screw 9, and the adjusting groove 7 facilitates the installation of the screw 9.

[0034] As attached Figure 3 As shown, a screw 9 is fixedly connected to one end of the shaft 8. The screw 9 is threaded into the inside of the threaded groove 6. A driven bevel gear 10 is fixedly connected to the outside of the shaft 8. A driving bevel gear 11 is rotatably connected to the inner wall of the adjusting groove 7. The driving bevel gear 11 and the driven bevel gear 10 are meshed. A motor 12 is fixedly installed on one side of the first pile body 1. The middle part of the driving bevel gear 11 is fixedly connected to the output end of the motor 12. The connection between the driving bevel gear 11 and the driven bevel gear 10 improves the convenience of the motor 12 when rotating.

[0035] As attached Figure 4 As shown, a limiting block 13 is fixedly connected to one end of the connecting column 5. The limiting block 13 is slidably connected inside the adjusting groove 7. The limiting block 13 facilitates limiting the movement distance of the connecting column 5.

[0036] As attached Figure 6 As shown, a buffer assembly is provided on the outside of the second pile body 3. The buffer assembly includes multiple grooves 14. The multiple grooves 14 are opened on the outside of the second pile body 3. Multiple fixing tubes 15 are fixedly connected inside the grooves 14. A first limiting ring 16 is fixedly connected to one end of the fixing tube 15. A second limiting ring 17 is slidably connected inside the fixing tube 15. A sliding tube 18 is fixedly connected inside the second limiting ring 17. A buffer spring 19 is fixedly connected inside the sliding tube 18. The grooves 14 facilitate the installation of the buffer shell 20 and the multiple buffer springs 19. The first limiting ring 16, in cooperation with the second limiting ring 17, helps to prevent the sliding tube 18 from coming out of the interior of the fixing tube 15.

[0037] As attached Figure 5 As shown, one end of multiple buffer springs 19 is fixedly connected to the inside of the groove 14, and one end of multiple sliding tubes 18 is fixedly connected to a buffer shell 20. A reflective strip 21 is provided on one side of the buffer shell 20, and the buffer shell 20 facilitates frontal contact with the impact force.

[0038] Working principle: After the first pile 1 is installed in a suitable position, when it is necessary to adjust the height of the second pile 3, the motor 12 is turned on. Its output end drives the active bevel gear 11 to rotate. At the same time, under the action of meshing with the driven bevel gear 10, the driven bevel gear 10 is driven to rotate. This causes the driven bevel gear 10 to drive the shaft 8 and then drive the screw 9 to rotate. Under the action of the threaded groove 6, the screw 9 drives the connecting column 5 to rise. This causes the connecting column 5 to drive the second pile 3 to slide outside the first pile 1, thereby adjusting the height of the second pile 3.

[0039] When a pedestrian accidentally hits the outside of the second pile 3, the impact force will contact the buffer shell 20 under the action of the buffer spring 19 pushing the buffer shell 20 to protrude from the outside of the second pile 3. This will cause the internal sliding tube 18 to drive the second limiting ring 17 to slide inside the fixed tube 15, thereby compressing the buffer spring 19. During the compression of the buffer spring 19, the impact force will be absorbed to a certain extent under the action of the elastic force, thus buffering the impact force of the pedestrian directly hitting the second pile 3.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
