Abstract
Description
Technical Field
[0001] This utility model provides a speed bump for highways, belonging to the technical field of speed bumps. Background Technology
[0002] Speed bumps are traffic safety facilities installed at intersections, schools, residential areas, and other areas where mandatory speed reduction is required. Their core function is to create a forced bump in the vertical direction, causing discomfort to drivers and passengers, thereby alerting and compelling drivers to voluntarily reduce their speed, thus preventing traffic accidents. Close observation reveals that common rubber or plastic speed bumps are not a continuous strip, but rather composed of multiple independent short segments installed side-by-side. This segmented design primarily provides a passageway for vehicles with narrow wheelbases, such as bicycles, electric bicycles, and motorcycles.
[0003] However, this classic segmented structure presents significant installation challenges. Since each speed bump segment is an independent unit, each segment needs to be individually fixed to the ground to ensure it doesn't shift or lift under repeated vehicle traffic, guaranteeing its stability and durability. Currently, the most common and reliable method is using expansion bolts. This means installers need to drill multiple holes in the road surface for each segment, then drive bolts in and tighten them one by one. For a complete speed bump, the number of bolts and drilling work increases exponentially with the number of segments, resulting in a cumbersome, time-consuming, and labor-intensive installation process with low efficiency and prolonged traffic disruption. Therefore, a new structural solution is urgently needed that retains the functional advantages of segmented speed bumps while significantly simplifying the installation process and improving efficiency. Utility Model Content
[0004] The technical problem this invention aims to solve is that fixing segmented speed bumps one by one with bolts is cumbersome and greatly reduces installation efficiency.
[0005] To solve the above problems, the proposed technical solution is as follows: a speed bump for highways, comprising a base, a locking speed bump, and splicing speed bumps; the base is fixedly installed on the highway surface, and a slot is provided inside the base; several splicing speed bumps are provided, and one locking speed bump is provided; the splicing speed bumps and locking speed bumps are spliced together, and a limiting rod that engages with the slot is fixedly connected below both the splicing speed bumps and the locking speed bump, and the locking speed bump is fixedly connected to the base by expansion bolts; the limiting rod is rotatably installed in the slot, and a connecting groove communicating with the slot is provided on the base, so that the connecting groove is perpendicular to the limiting rod and facilitates the passage of the limiting rod.
[0006] Preferably, both the locking speed bump and the splicing speed bump are fixedly connected to a connecting rod located in the connecting groove below, and the connecting rod is vertically fixedly connected to the limiting rod.
[0007] Preferably, the diameter of the limiting rod corresponds to the height of the slot, and there is a gap between both ends of the limiting rod and the inner wall of the slot.
[0008] Preferably, the card slot and the connecting slot have an open end on one side of the base, and the locking deceleration band is located near the open end of the card slot.
[0009] Preferably, the base has bolt holes near the opening end of the slot, and the locking speed bump has countersunk holes. The expansion bolts located in the countersunk holes fix the locking speed bump to the base through the bolt holes.
[0010] The beneficial effects of this utility model are:
[0011] 1. This utility model achieves a significant increase in installation efficiency through a clever "one-to-many" locking mechanism. In the entire speed bump assembly, only the locking speed bump section at the end needs to be finally fixed using expansion bolts. Once the locking speed bump is firmly anchored to the base, it forms a continuous mechanical linkage with the other spliced speed bumps within the slot through the limiting rod, effectively constraining the displacement of all adjacent segments. This ensures the integrity and stability of the entire speed bump under repeated vehicle traffic. This greatly reduces the workload of bolt drilling and tightening, significantly improving construction speed.
[0012] 2. The limiting rod is rotatably set in the slot, and the connecting groove for easy passage of the limiting rod is set perpendicular to the limiting rod; when it is necessary to disassemble and repair a single speed bump, it is not necessary to remove all the speed bumps; simply remove the locking speed bump, slide the splicing speed bump to leave enough gap for the splicing speed bump to be replaced, and then remove it by rotating the splicing speed bump.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] Reference Appendix Figure 1 , 2 This utility model provides a speed bump for highways, comprising a base 1, a locking speed bump 2, and splicing speed bumps 3. The base 1 is fixedly installed on the highway surface, and a slot 4 is provided inside the base 1. Several splicing speed bumps 3 are provided, and one locking speed bump 2 is provided. The splicing speed bumps 3 and the locking speed bumps 2 are spliced together, and a limiting rod 5 that engages with the slot 4 is fixedly connected below both the splicing speed bumps 3 and the locking speed bumps 2. The locking speed bump 2 is fixedly connected to the base 1 by expansion bolts. The limiting rod 5 engages with the slot 4, which can limit the vertical displacement of the speed bumps. The spliced speed bumps can play a role in mutually limiting each other in the horizontal direction. Only the locking speed bump 2 needs to be locked and fixed to complete the installation of all speed bumps, reducing the number of expansion bolts used and greatly improving installation efficiency.
[0020] Reference Appendix Figure 3 The limiting rod 5 is rotatably mounted within the slot 4. A connecting groove 7, communicating with the slot 4, is provided on the base 1, allowing the limiting rod 5 to pass through. The connecting groove 7 is perpendicular to the limiting rod 5. A connecting rod 6, located within the connecting groove 7, is fixedly connected below both the locking speed bump 2 and the splicing speed bump 3, and is vertically fixed to the limiting rod 5. When the limiting rod 5 rotates to a state parallel to the connecting groove 7, the splicing speed bump 3 can be easily removed upwards, improving the convenience of replacement and maintenance. The diameter of the limiting rod 5 corresponds to the height of the slot 4, ensuring the stability of the vertical displacement restriction of the speed bump. Gaps exist between the two ends of the limiting rod 5 and the inner wall of the slot 4 to prevent interference and collision between the limiting rod 5 and the inner wall of the slot 4 during rotation.
[0021] Reference Appendix Figure 3 , 4 The slot 4 and the connecting slot 7 have open ends on one side of the base 1. Therefore, the connecting slot 7 and the slot 4, which are closed at the other end, can limit the splicing speed bump 3 at the end. The locking speed bump 2 is located near the open end of the slot 4, which can meet the operation mode of first installing the splicing speed bump 3 and finally installing the locking speed bump 2.
[0022] Reference Appendix Figure 1 , 4 The base 1 has bolt holes 8 near the opening of the slot 4, and the locking speed bump 2 has countersunk holes 9 to prevent vehicles and pedestrians from having too much impact on the expansion bolts. The expansion bolts located in the countersunk holes 9 fix the locking speed bump 2 to the base 1 through the bolt holes 8.
[0023] The principle of this utility model
[0024] The installation process of this device is efficient and convenient. First, the prefabricated base 1 is fixed to the road surface. Then, the speed bumps 3 are installed one by one, as shown in the attached diagram. Figure 4 The individual spliced speed bumps 3 are sequentially installed onto the base 1 by engaging the limiting rod 5 into the slot 4. Finally, the locking speed bump 2 is installed onto the base 1 in the same way and secured to the base 1 using bolt holes 8 and expansion bolts. This completes the installation of the entire speed bump. (See attached diagram.) Figure 1 , 3 This process simplifies the traditional method of repeatedly drilling and fixing each speed bump segment into a single placement and single-point locking, resulting in an order-of-magnitude improvement in construction efficiency. It should be noted that compared to traditional speed bump installation, this application adds an installation step for the base 1; although this adds an extra step, it essentially only involves locking two components. Compared to the traditional method of drilling and fixing each speed bump individually, this application still demonstrates significant efficiency.
[0025] If the locking speed bump 2 is damaged and needs replacement, simply remove the expansion bolts to replace it. However, when a section of the spliced speed bump 3 (not the locking speed bump 2) is damaged due to long-term use and needs replacement, the repair and disassembly process is equally simple and does not require damaging the overall structure. The repair personnel first use tools to unscrew the expansion bolts securing the locking speed bump 2, releasing its locking constraint on the entire assembly, and remove the locking speed bump 2, leaving sufficient space. Then, slide the spliced speed bump 3 horizontally, creating sufficient operating space on both sides of the damaged spliced speed bump 3 that needs replacement. Next, manually rotate the damaged spliced speed bump 90°, causing the limiting rod 5 below it to rotate synchronously 90° within the slot 4 (since sufficient space has been provided for the spliced speed bump 3, other spliced speed bumps 3 on both sides will not interfere or collide with it when rotating it), so that the limiting rod 5 is in a position parallel to the connecting slot 7, and then directly remove the section of speed bump upwards. When replacing a new spliced speed bump 3, the operation can be quickly restored by reversing the steps. Specifically, the limiting rod 5 of the new spliced speed bump 3 is inserted through the connecting groove 7 parallel to the connecting groove 7 and into the locking groove 4. The spliced speed bump is rotated 90° so that the limiting rod 5 is perpendicular to the connecting groove 7. Then, the other spliced speed bumps 3 are pushed, and the locking speed bump 2 is installed, forming a complete structure again. This design enables independent maintenance of individual components, solving the maintenance difficulties caused by the "one-to-many" locking mechanism of this application.
[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
