Description

Technical Field

[0001] This utility model relates to the field of traffic safety facilities technology, and in particular to a pre-embedded fixed support structure for speed bumps. Background Technology

[0002] Speed ​​bumps, a common traffic safety facility, are widely installed in road sections where vehicles need to slow down, such as school, hospital, residential entrances, and toll booths. They physically force vehicles to reduce speed, effectively improving the safety of drivers and pedestrians.

[0003] Currently, most speed bumps on the market are modular sections made of rubber or cast iron. The traditional installation method usually involves placing these speed bump modules directly on the hardened road surface and then using an electric drill to drill holes in the road surface at the pre-drilled positions for the speed bumps.

[0004] After drilling, expansion bolts or long steel nails are driven in, using the expansion force of the bolts or the friction of the nails to forcibly fix the speed bump to the road surface. This installation method can achieve fixation in the short term, but its inherent defects are also very obvious.

[0005] Speed ​​bumps operate in extremely harsh environments, constantly enduring high-intensity impacts and high-frequency vibrations from passing vehicles. Under such continuous impact and vibration, the locking force of expansion bolts directly anchored to the road surface (especially asphalt) gradually decreases, and the bolts themselves become prone to loosening.

[0006] Once the bolts loosen, gaps will form between the speed bump module and the road surface, causing abnormal noises when vehicles drive over it and exacerbating the loosening process. More seriously, loose modules may shift or even detach, losing their deceleration function and becoming a new traffic safety hazard. Furthermore, when a speed bump needs to be replaced, removing these corroded bolts is very difficult, and installing a new module often requires re-drilling, causing secondary damage to the road surface.

[0007] Therefore, the existing technology that relies on expansion bolts for direct fixing has core problems such as low installation efficiency, insufficient fixing firmness, poor long-term reliability, and difficulty in later maintenance and replacement.

[0008] Therefore, this utility model proposes a pre-embedded fixed bracket structure for speed bumps to overcome the shortcomings of the prior art. Utility Model Content

[0009] In view of the problems of low installation efficiency, insufficient fixing firmness, poor long-term reliability, and difficulty in maintenance and replacement of speed bumps in the existing technology, this utility model aims to provide a speed bump pre-embedded fixing bracket structure with improved structure that can effectively solve the above problems.

[0010] This utility model provides a pre-embedded fixing bracket structure for speed bumps, including a speed bump, a pre-embedded box, a locking assembly, and a fixing mechanism.

[0011] The pre-embedded box is buried inside the road surface, the speed bump is set on the top of the pre-embedded box, the locking assembly is set at both ends of the speed bump, and the fixing mechanism is set inside the speed bump.

[0012] The locking assembly includes a sub-lock base plate, a sub-lock head fixedly connected to the front of the sub-lock base plate, and a female lock base plate; a positioning pin is fixedly connected to the female lock base plate; a female lock clamp 1 and a female lock clamp 2 are rotatably connected to the female lock base plate and are used to clamp the sub-lock head; a spring 1 is respectively connected between the female lock clamp 1 and the female lock base plate and between the female lock clamp 2 and the female lock base plate.

[0013] The fixing mechanism includes a fixing bolt body, a push rod slidably connected inside the fixing bolt body, and a nut threadedly connected to the outside of the fixing bolt body; a second positioning pin is also fixedly connected inside the fixing bolt body; a fixing claw is rotatably connected to the second positioning pin and is located below the push rod; a second spring is located between the bottom of the push rod and the inner wall of the fixing bolt body.

[0014] Preferably, the first spring is a compression spring; the first spring is installed in the spring seat between the first female locking clamp and the base plate of the female locking clamp, and in the spring seat between the second female locking clamp and the base plate of the female locking clamp. This arrangement is used to provide a reliable rebound force when the female locking clamp head is removed, so as to push the first female locking clamp and the second female locking clamp to automatically clamp inward.

[0015] Preferably, the second spring is a compression spring; the second spring is sleeved on the bottom of the push rod and located between the push rod and the inner bottom of the fixing bolt body; the second spring is used to automatically push the push rod upward to reset when the external force is released during the installation operation.

[0016] Preferably, the fixing claw has one end rotatably connected to the positioning pin, and the other end is formed into a hook-shaped structure for engaging with the inner wall of the embedded box; correspondingly, the inner wall of the embedded box is provided with a slot or support structure for engaging with the hook-shaped structure of the fixing claw, and the two work together to achieve a firm anchoring.

[0017] Preferably, the speed bump and the embedded box are respectively provided with positioning holes for the fixing mechanism to pass through and be positioned; the positioning holes penetrate through the thickness direction of the speed bump to ensure that the fixing mechanism can accurately pass through the speed bump and extend into the interior of the embedded box.

[0018] Preferably, the bottom of the push rod is provided with a pressing surface for directly contacting and pressing the fixing claw; the top of the push rod is provided with a pressing head for manual pressing operation, so that the operator can apply pressure to retract the fixing claw.

[0019] Preferably, the female locking head has a tapered guide surface for guiding the first and second female locking clamps to rotate to both sides; the guide surface makes the insertion action smoother and can automatically open the female locking clamps.

[0020] Preferably, the nut is located on the upper outer part of the fixing bolt body; by tightening the nut, the fixing bolt body can be pulled upward, thereby making the already unfolded fixing claw more tightly fixed in the embedded box, providing the final locking force and eliminating gaps.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model solves the problems of cumbersome installation process, reliance on road drilling, and difficulty in disassembly and maintenance of existing speed bumps by setting a fixing mechanism consisting of a push rod, spring, fixing claw, and nut. It achieves a convenient installation effect, which can be retracted and inserted by pressing down, automatically unfolded and snapped when released, and firmly locked by tightening the nut. This greatly improves construction efficiency and facilitates subsequent modular replacement and maintenance.

[0023] 2. This utility model solves the problem of loose splicing between existing speed bump modules and easy misalignment or separation under vehicle pressure by setting a locking assembly that includes a daughter locking head and a spring-returning mother locking clamp. It achieves a quick connection effect of automatic locking upon insertion, ensuring that multiple speed bump modules are connected into a stable whole, thus improving driving safety and comfort.

[0024] 3. This utility model solves the problem that traditional speed bumps are easily damaged by direct nailing and difficult to repair once loosened by using a pre-embedded box with an internal anchoring structure. It transforms complex road construction into a standardized pre-embedded operation, protects the road base, and enhances the impact resistance and service life of the overall speed bump structure.

[0034] Example:

[0035] Please refer to Figures 1 to 5 This utility model provides a pre-embedded fixed bracket structure for speed bumps, which aims to solve the shortcomings of existing speed bump structures in terms of module connection reliability and ease of fixing to the road surface.

[0036] like Figure 1 and Figure 2 As shown, the pre-embedded fixing bracket structure for the speed bump 1 includes a pre-embedded box 2 and the speed bump 1 mounted on top of the pre-embedded box 2. The pre-embedded box 2 serves as the mounting base for the entire bracket, embedded inside the road surface, providing a support platform for the installation of the speed bump 1. The speed bump 1, as the main part compacted by vehicles, integrates a modular connection and road surface fixing mechanism.

[0037] The pre-embedded fixing bracket structure of the speed bump 1 also includes a locking assembly 3 and a fixing mechanism 4. The locking assembly 3 is located at both ends of the speed bump 1 and is used to achieve quick connection between the speed bump 1 modules. The fixing mechanism 4 is located inside the speed bump 1 and is used to firmly fix the speed bump 1 to the pre-embedded box 2.

[0038] The detailed structure of the locking assembly 3 includes a daughter locking base plate 31 and a mother locking base plate 34. The daughter locking head 32 is fixedly connected to the front of the daughter locking base plate 31. A positioning pin 33 is fixedly connected to the mother locking base plate 34. Mother locking clamps 35 and 37 are rotatably connected to the mother locking base plate 34, both used to clamp the daughter locking head 32. Springs 36 are respectively connected between mother locking clamp 35 and the mother locking base plate 34, and between mother locking clamp 37 and the mother locking base plate 34. Springs 36 are compression springs, installed in spring seats between mother locking clamp 35 and the mother locking base plate 34, and between mother locking clamp 37 and the mother locking base plate 34. Their function is to provide tension when the daughter locking head 32 is inserted, and to push mother locking clamps 35 and 37 inwards to clamp when the daughter locking head 32 is removed. The daughter lock head 32 has a tapered guide surface for guiding the mother lock clamp 35 and the mother lock clamp 37 to rotate to both sides.

[0039] The detailed structure of the fixing mechanism 4 includes a fixing bolt body 46. A push rod 41 is slidably connected inside the fixing bolt body 46. The bottom of the push rod 41 is provided with a pressing surface for directly contacting and pressing the fixing claw 43, and the top of the push rod 41 is provided with a pressing head for manual pressing operation. A nut 42 is threadedly connected to the outside of the fixing bolt body 46, specifically located at the upper outer end of the fixing bolt body 46. A second positioning pin 44 is fixedly connected inside the fixing bolt body 46. The fixing claw 43 is rotatably connected to the second positioning pin 44 and is located below the push rod 41. The fixing claw 43 has one end rotatably connected to the second positioning pin 44, and the other end is a hook-shaped structure for engaging the inner wall of the embedded box 2. A second spring 45 is located between the bottom of the push rod 41 and the inner wall of the fixing bolt body 46. The second spring 45 is a compression spring, which is sleeved on the bottom of the push rod 41 and located between the push rod 41 and the inner bottom of the fixing bolt body 46, and is used to push the push rod 41 upward. Both the speed bump 1 and the embedded box 2 are provided with positioning holes for the fixing mechanism 4 to pass through and be positioned. The positioning holes penetrate the thickness direction of the speed bump 1. The inner wall of the embedded box 2 is provided with a slot or support structure for engaging with the fixing claw 43.

[0040] Reference Figures 1 to 5During the connection process between speed bump 1 modules, the sub-lock head 32 at one end of speed bump 1 aligns with and pushes between the first and second female lock clamps 35 and 37 at the other end of speed bump 1. The tapered guide surface at the front end of the sub-lock head 32 squeezes the first and second female lock clamps 35 and 37, causing the first and second female lock clamps 35 and 37 to overcome the elastic force of the first spring 36 and rotate to both sides around their rotation connection point on the base plate 34 of the female lock. When the sub-lock head 32 is fully in the predetermined position, the rebound force of the first spring 36 pushes the first and second female lock clamps 35 and 37 to rotate inward, thereby tightly clamping the sub-lock head 32. This spring-reset type clamp and clamp head cooperation structure ensures the speed and firmness of the connection between speed bump 1 modules.

[0041] During the installation of the speed bump 1 and the embedded box 2, press down on the top of the push rod 41. The push rod 41 moves downward along its sliding path within the fixing bolt body 46. The bottom pressing surface of the push rod 41 presses against the fixing claw 43, simultaneously compressing the second spring 45 sleeved at its bottom. After being compressed, the fixing claw 43 rotates inward around the second positioning pin 44 and retracts into the fixing bolt body 46. At this time, the entire fixing mechanism 4 is passed through the positioning holes on the speed bump 1 and the embedded box 2. The push rod 41 is released, and the second spring 45 rebounds, pushing the push rod 41 upward. During the upward movement, the fixed claw 43 is pushed to rotate outward around the positioning pin 44, so that the hook-shaped structure of the fixed claw 43 engages with the slot or support structure on the inner wall of the embedded box 2. Finally, the nut 42, which is threaded to the outside of the fixing bolt body 46, is tightened downward. The axial locking force of the nut 42 pulls the fixing bolt body 46 upward, thereby firmly fixing the unfolded fixed claw 43 in the embedded box 2. This anchoring structure, which is pressed and retracted, spring-unfolded, and locked by the nut 42, ensures the ease of installation of the speed bump 1 body and the high stability after fixing.

[0042] In a preferred embodiment, in order to enhance the smoothness of the connection and the reliability of the reset of the locking assembly 3, the sub-lock head 32 has a tapered guide surface for guiding the first locking clamp 35 and the second locking clamp 37 to rotate to both sides. The first spring 36 is a compression spring and is installed in the spring seat between the first locking clamp 35 and the base plate 34 of the locking assembly, and in the spring seat between the second locking clamp 37 and the base plate 34 of the locking assembly.

[0043] As another preferred embodiment, in order to improve the ease of operation and the firmness of fixing mechanism 4, the top of push rod 41 is provided with a pressing head for manual pressing operation, and the bottom is provided with a pressing surface for directly contacting and pressing fixing claw 43. Spring 45 is a compression spring, which is sleeved on the bottom of push rod 41. The end of fixing claw 43 is a hook-shaped structure for engaging with the inner wall of embedded box 2. The inner wall of embedded box 2 is provided with a corresponding slot or support structure for engaging with fixing claw 43. The deceleration band 1 and embedded box 2 are respectively provided with positioning holes for fixing mechanism 4 to pass through and be positioned. Nut 42 is provided on the upper outer part of fixing bolt body 46 for final locking and lifting.

[0044] The working principle is as follows:

[0045] When connecting speed bump 1 modules, the sub-lock head 32 at one end of speed bump 1 aligns with and pushes against the female lock clamps 35 and 37 at the other end of speed bump 1. The tapered guide surface at the front end of the sub-lock head 32 gradually contacts and squeezes the female lock clamps 35 and 37, causing them to overcome the spring force of spring 36 and rotate open around their rotational connection point with the positioning pin 33 on the base plate 34 of the female lock. When the sub-lock head 32 is fully engaged in the predetermined locking position of the female lock clamps 35 and 37, spring 36 returns to its original length in the open state, and its rebound force pushes the female lock clamps 35 and 37 to quickly rotate inward and clamp the sub-lock head 32, thus achieving a quick and stable connection between the two speed bump 1 modules. This locking assembly 3 design effectively solves the problem of unstable connection between speed bump 1 modules.

[0046] When the speed bump 1 needs to be installed on the road pre-embedded box 2, first press the pressing head on the top of the push rod 41. The push rod 41 moves downward along its path slidably connected to the inside of the fixing bolt body 46. The pressing surface at the bottom of the push rod 41 presses the fixing claw 43 downward, while simultaneously compressing the second spring 45 sleeved at its bottom. After being compressed, the fixing claw 43 rotates inward around the rotational connection point between the inside of the fixing bolt body 46 and the second positioning pin 44, retracting into the inside of the fixing bolt body 46. At this time, the entire fixing mechanism 4, together with the speed bump 1, aligns and passes through the positioning hole on the speed bump 1 and the pre-embedded box 2. When the fixing mechanism 4 is in place, release the push rod 41. The second spring 45 loses its pressure and quickly rebounds, pushing the push rod 41 upward. During the upward movement of the push rod 41, the fixing claw 43 loses the pressure from the push rod 41 and, under the action of the rebound force of the second spring 45, rotates outward around the second positioning pin 44, and its hook-like structure engages with the slot or support structure provided on the inner wall of the pre-embedded box 2. Finally, tighten the nut 42, which is threaded onto the outside of the fixing bolt body 46, downwards. The downward tightening force of the nut 42 will pull the fixing bolt body 46 upwards, thereby making the already unfolded fixing claw 43 more tightly engaged with the slot or support structure on the inner wall of the embedded box 2, ultimately fixing the speed bump 1 firmly to the embedded box 2. This fixing mechanism 4 design significantly improves the convenience and firmness of fixing the speed bump 1 to the road surface.
