Description

Technical Field

[0001] This utility model relates to the field of speed bump technology, specifically a speed bump that is easy to maintain. Background Technology

[0002] In the transportation sector, speed bumps are a common road facility used to control vehicle speed and ensure pedestrian and traffic safety. However, existing speed bumps have some problems in terms of installation and maintenance. The installation process of traditional speed bumps is relatively cumbersome, often requiring precise drilling positions; otherwise, installation deviations are likely to occur, affecting their stability. Moreover, once installed, if the speed bump is damaged, it usually needs to be replaced entirely, which not only increases maintenance costs but also wastes resources. In addition, the connecting parts between the speed bump and the ground, such as screws, are usually directly exposed to the external environment and are easily corroded by rainwater, dust, etc., leading to rust. Rusty screws not only affect the stability of the connection between the speed bump and the ground but also increase the difficulty of disassembly and maintenance, reducing the service life of the speed bump. To solve these problems, a speed bump that is easy to maintain has emerged.

[0003] The applicant discovered a Chinese patent, "A Highway Speed ​​Bump Easy to Maintain," with publication number CN221072354U. This patent mainly involves a first speed bump with at least two bolt holes at its lower end. A second speed bump is installed on the side of the first speed bump, with two first slots at the side end of the first speed bump and two second rods fixedly installed at the side end of the second speed bump. Multiple second speed bumps are spliced ​​together left and right. After installing the last second speed bump, the user slides the two first rods from the first speed bump into the second slots on the side of the last second speed bump. After the two first rods slide into the two second slots, they are fixed with screws. At this point, the installation of the two first speed bumps and multiple second speed bumps is complete. The overall installation is convenient and quick, and it eliminates the need to connect each second speed bump to the road using ground stakes, greatly reducing the overall installation difficulty. However, this device uses a two-within-one-barrel installation method, which may lead to detachment or loosening due to insecure fixing during use, potentially causing safety accidents. Therefore, we propose a speed bump that is easy to maintain. Utility Model Content

[0010] As a further embodiment of this utility model: a T-shaped protrusion is provided on one side of the A speed bump base, and a T-shaped groove is provided on one side of the B speed bump base.

[0011] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0012] 1. This utility model features a threaded hole at the top of the base, fixing holes around the base, and T-shaped protrusions and T-shaped grooves on both sides of the base. Compared to other speed bumps on the market, this design allows for easier installation. First, the base is installed by connecting the fixing holes on both sides of the base with the T-shaped protrusions and grooves. Then, holes are drilled around the base, and expansion screws are used for fixing. Connecting the T-shaped protrusions and grooves first effectively prevents drilling errors and enhances the stability of the base installation. Finally, the speed bump is connected via the threaded hole at the top, ensuring a tight and reliable connection between the speed bump and the base.

[0013] 2. This utility model features mounting holes at both ends of the ramps on both sides of the connecting speed bump, speed bump A, and speed bump B. The mounting holes have threaded grooves above them and are connected to dust covers. This design effectively prevents the internal screws from directly contacting the external environment, greatly reducing the risk of screw rust. As a key component connecting the speed bump and the base, rust on the screws not only affects the stability of the connection but also increases the difficulty of disassembly and maintenance. With the protection of the dust covers, the screws can always remain in good condition, ensuring a tight and reliable connection between the speed bump and the base. This not only extends the service life of the speed bump but also reduces maintenance costs.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see the appendix Figure 1 -Appendix Figure 5 This utility model discloses a speed bump that is easy to maintain, including a speed bump A 1, a connecting speed bump 2, and a speed bump B 3. The speed bump A 1, connecting speed bump 2, and speed bump B 3 are securely installed on top of a base 4 in the installation sequence. The base 4 is designed with fixing holes 41 around its bottom, and T-shaped protrusions 42 and T-shaped grooves 43 on both sides of the base 4. Threaded holes 44 are provided around the top of the base 4. At the same time, mounting holes 21 are provided at both ends of the ramps on both sides of the connecting speed bump 2. Threaded grooves 24 are provided inside the mounting holes 21, and screws 22 are installed inside. A dust cover 23 can be connected to the threaded grooves 24 inside the mounting holes 21 via threads. With this design, when the speed bump is damaged, only the damaged part needs to be replaced. At the same time, the design of the dust cover 23 can prevent the screws 22 from being exposed to the outside environment for a long time, which may cause rust or other problems, and facilitates disassembly and installation during maintenance.

[0024] In embodiment 1, threaded holes 44 are provided around the top of the base 4, and fixing holes 41 are provided around the top of the base 4. A T-shaped protrusion 42 is provided in the center of one side of the base 4, and a T-shaped groove 43 is provided in the center of one side of the base 4. Mounting holes 21 are provided at both ends of the ramps connecting the speed bump 2, speed bump A 1 and speed bump B 3. Threaded grooves 24 are provided inside the mounting holes 21. Screws 22 are installed inside the mounting holes 21 and are connected to the threaded holes 44 on the top of the base 4. A dust cover 23 is provided above the screws 22, and threads are provided on the side of the dust cover 23, which can be connected to the threaded grooves 24 inside the mounting holes 21.

[0025] Specifically, threaded holes 44 are evenly distributed around the top of the base 4, providing reliable fixing points for connecting speed bump 2, speed bump A 1, and speed bump B 3. Fixing holes 41 are also provided around the base 4, playing a crucial role in the installation process. Furthermore, a T-shaped protrusion 42 is carefully placed at the center of one side of the base 4, and correspondingly, a T-shaped groove 43 is placed at the center of the other side of the base 4. This design greatly enhances the stability and accuracy of the base 4's installation, while also facilitating the connection between multiple bases 4. Moreover, the structural design for connecting speed bump 2, speed bump A 1, and speed bump B 3 is also very... Ingeniously designed, each of the two ends of the ramp has mounting holes 21, and the inner side of the mounting holes 21 has threaded grooves 24. During installation, screws 22 are installed inside the mounting holes 21, and these screws 22 are tightly connected to the threaded holes 44 on the top of the base 4, ensuring a firm connection between the speed bump and the base 4. At the same time, a dust cover 23 is provided above the screws 22. The dust cover 23 has threads on its side, which can perfectly connect with the threaded grooves 24 on the inner side of the mounting holes 21. This design effectively avoids direct contact between the internal screws 22 and the external environment, greatly reducing the risk of the screws 22 rusting, thereby extending the service life of the speed bump and reducing maintenance costs.

[0026] In embodiment 2, grooves 5 are provided on both sides of the connecting speed bump 2, and threaded holes 44 are provided inside the grooves 5. A connecting block 6 is installed above the grooves 5. A hole is provided in the middle of the connecting block 6, and the screw 22 above it can pass through the hole of the connecting block 6 and connect with the threaded hole 44 inside the groove 5. A dust plug 61 is provided above the screw 22. A T-shaped protrusion 42 is provided on one side of the base 4 of speed bump 1, and a T-shaped groove 43 is provided on one side of the base 4 of speed bump 3.

[0027] Specifically, grooves 5 are provided on both sides of the connecting speed bump 2, and threaded holes 44 are provided on the inner side of these grooves 5. A connecting block 6 is installed above the grooves 5, and a hole is provided in the middle of the connecting block 6. The screw 22 above can accurately pass through the hole of the connecting block 6 and be tightly connected with the threaded hole 44 on the inner side of the groove 5. This connection method is not only firm and reliable, but also makes the structure of the connecting speed bump 2 more stable. At the same time, a dust plug 61 is provided above the screw 22, which effectively prevents dust and other impurities from entering and avoids the screw 22 from rusting, which would cause difficulties in disassembly for subsequent maintenance. It also ensures the stability and reliability of the connection. A T-shaped protrusion 42 is carefully provided on one side of the base 4 of speed bump A 1. Correspondingly, a T-shaped groove 43 is provided on one side of the base 4 of speed bump B 3. This design makes the connection between speed bump A 1 and speed bump B 3 tighter and more stable. The cooperation between the T-shaped protrusion 42 and the T-shaped groove 43 not only improves the overall structural strength of the speed bump, but also provides convenience for installation and disassembly, making maintenance work more efficient and convenient.

[0028] Working principle:

[0029] First, the T-shaped protrusions 42 and T-shaped grooves 43 on both sides of the base 4 are used for final connection to initially determine the position and avoid deviations in subsequent drilling, while also enhancing the stability of the base 4 installation. Next, holes are drilled through the fixing holes 41 around the base 4, and expansion screws 22 are used to fix the base 4. The threaded holes 44 around the top of the base 4 are used for connection with the speed bump. Screws 22 are installed in the mounting holes 21 at both ends of the ramps on both sides of speed bump A 1, connecting speed bump 2, and speed bump B 3. The screws 22 are connected to the threaded holes 44 on the top of the base 4 to achieve a tight fit between the speed bump and the base 4. The dust cover 23 above the screws 22 and the connecting speed bump 2 are also included. The dust plug 61 above the screw 22 in groove 5 effectively prevents the internal screw 22 from directly contacting the external environment, reducing the risk of the screw 22 rusting. The groove 5 connecting the two sides of the speed bump 2 is further reinforced with the screw 22 through the connecting block 6. When the speed bump is damaged, only the damaged part needs to be replaced, without replacing the whole thing, which reduces maintenance costs and improves maintenance efficiency. The T-shaped protrusion 42 on one side of the base 4 of speed bump A and the T-shaped groove 43 on one side of the base 4 of speed bump B cooperate to make the overall connection of the speed bump tighter and more stable, improve the structural strength, and also provide convenience for installation and disassembly. At this point, the entire workflow is complete.
