Description

Technical Field

[0001] This utility model relates to the field of speed bump technology, specifically a combined speed bump with nighttime warning and buffer functions. Background Technology

[0002] Speed ​​bumps are traffic facilities installed on highways to slow down passing vehicles. They are typically strip-shaped or dotted, and are usually made of rubber or metal, often in alternating yellow and black colors to attract visual attention. Speed ​​bumps slightly raise the road surface to achieve the purpose of slowing down vehicles. They are generally installed at highway intersections, industrial and mining enterprises, school entrances, residential areas, and other sections of road where vehicles need to slow down, as well as sections prone to traffic accidents. Current alloy material speed bumps suffer from poor cushioning performance, while rubber material speed bumps are easily damaged. Therefore, this paper proposes a combined speed bump with nighttime warning and cushioning functions. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a combined speed bump with nighttime warning and buffer functions. By using the inner speed bump as a supporting and pressure-resistant frame and the outer speed bump as a buffer structure, the buffering performance of the combined speed bump is improved, and its service life can also be extended.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a combined speed bump with nighttime warning and buffering functions, comprising an inner speed bump made of alloy material and an outer speed bump made of rubber material, wherein the outer speed bump is fitted onto the surface of the inner speed bump to reduce the impact from the vehicle; The inner speed bump has a positioning channel on one side and a positioning strip that matches the positioning channel fixed on the other side. Adjacent speed bumps are connected through the positioning channel and the positioning strip. The inner speed bump has several sets of reflective beads detachably installed at intervals on its inclined end face. These reflective beads are exposed to the external environment and reflect the vehicle lights to serve as a warning.

[0005] Preferably, the inner speed bump has several sets of grooves on both sides, and the outer speed bump has through holes at the positions corresponding to the grooves.

[0006] Preferably, the inner speed bump has several sets of grooves at intervals on its inclined end face, and reflective beads are installed in the corresponding grooves. The outer speed bump has through holes at the positions corresponding to the grooves.

[0012] This utility model provides a combined speed bump with nighttime warning and buffer functions, which has the following advantages compared with the prior art: 1. This utility model is equipped with an outer speed bump and an inner speed bump. By using the inner speed bump as a supporting and pressure-resistant skeleton and the outer speed bump as a buffer structure, the buffering performance of the combined speed bump is improved, and the service life of the combined speed bump can also be extended.

[0013] 2. This utility model is equipped with reflective beads, screws, and screw holes.

Detailed Implementation

[0017] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Current alloy material speed bumps suffer from poor cushioning performance, while rubber material speed bumps are prone to damage. For example... Figures 1-7 As shown, a combined speed bump with nighttime warning and cushioning functions includes an inner speed bump 1 made of alloy material and an outer speed bump 7 made of rubber material. The outer speed bump 7 is fitted onto the surface of the inner speed bump 1 to reduce the impact from vehicles. The outer speed bump 7 is bonded to the surface of the inner speed bump 1 with adhesive. By using the inner speed bump 1 made of alloy material and the outer speed bump 7 made of rubber material together, with the inner speed bump 1 acting as a supporting and pressure-resistant frame and the outer speed bump 7 acting as a cushioning structure, the cushioning performance of the combined speed bump is improved, and its service life can also be extended.

[0019] Specifically, the inner speed bump 1 has several sets of grooves 3 on both sides, and the outer speed bump 7 has through holes 13 at the positions corresponding to the grooves 3. The inner speed bump 1 has several sets of grooves 4 at intervals on its inclined end face, and the outer speed bump 7 has through holes 14 at the positions corresponding to the grooves 4.

[0020] When installing speed bumps, after the outer speed bump 7 is placed on the inner speed bump, the groove 3 is aligned with the through hole 13, and the groove 4 is aligned with the through hole 14. Workers can use bolts to pass through the groove 3 and the through hole 13 to fix the outer speed bump 7 and the inner speed bump 1 to the road.

[0021] To ensure that the speed bumps are aligned at a certain height during connection, a positioning channel 5 is provided on one side of the inner speed bump 1, and a positioning strip 6 that matches the positioning channel 5 is fixed on the other side. Adjacent speed bumps are connected through the positioning channel 5 and the positioning strip 6.

[0022] When splicing two speed bumps, first fix one speed bump (denoted as speed bump A) to the road. Then, insert the positioning strip 6 of the other speed bump (denoted as speed bump B) into the positioning groove 5 of speed bump A to achieve alignment and connection between speed bump A and speed bump B. Finally, fix speed bump B to the road. Repeat the above operation to splice multiple speed bumps.

[0023] To improve the reflective effect and warn the driver, several sets of reflective beads 12 are detachably installed in the multiple sets of grooves 4 on the inclined end face of the inner speed bump 1. That is, each groove 4 has a reflective bead 12 installed individually. The reflective beads 12 are exposed to the external environment and reflect the vehicle lights to warn the driver.

[0024] The specific installation method for reflective beads 12 is as follows: The inner wall of the second tank 4 is provided with a screw hole 9, and a screw rod 10 is connected to the screw hole 9 by an internal thread. The end of the screw rod 10 is fixed with a connecting seat 11 for mounting the reflective beads 12.

[0025] When the reflective bead 12 breaks or is otherwise damaged, the connecting seat 11 can be rotated to drive the screw 10 to rotate, disengaging the screw 10 from the screw hole 9, thus removing the reflective bead 12. The reverse operation allows for the installation of a new reflective bead in the groove 4, making the process convenient.

[0026] After the outer speed bump 7 is fitted onto the inner speed bump 1, in order to align the groove 3 with the through hole 13 and the groove 4 with the through hole 14, a limiting block 15 is fixed at the top of the positioning strip 6 to fit the outer speed bump 7 into the designated position. After fitting, one end of the outer speed bump 7 abuts against the limiting block 15 for limiting.

[0027] In this embodiment, multiple drainage grooves 8 are evenly formed on the surface of the outer speed bump 7.

[0028] In this embodiment, several sets of reinforcing plates 2 are fixed inside the inner speed bump 1 to increase the support stability of the speed bump.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
