[0005] The objective of this utility model can be achieved by adopting the following technical solution:
[0006] A highway speed bump includes a rubber speed bump and mounting grooves evenly distributed on both sides of the rubber speed bump. The bottom sides of the rubber speed bump are vertically provided with tapered inserts below the mounting grooves. The inner bottom of the tapered inserts is vertically provided with sliding grooves, and the inner top of the tapered inserts is provided with hidden grooves. The sliding grooves and hidden grooves are connected.
[0007] A nut is vertically slidably installed inside the slide, and a spring is fixedly installed between the bottom end of the nut and the inner bottom of the slide;
[0008] Bolts are vertically installed inside the mounting slot, and the bolts extend through the concealed slot into the interior of the slide and are threadedly connected to the nut.
[0009] A reinforcement mechanism is provided at the top of the outer side of the tapered insertion rod.
[0010] Preferably, the inner diameter of the concealed groove is greater than the diameter of the bolt head, and the depth of the concealed groove is greater than the thickness of the bolt head.
[0011] Preferably, the outer side of the tapered insert is provided with anti-slip grooves evenly distributed along the vertical direction, and the anti-slip grooves are circular in shape.
[0012] Preferably, the reinforcement mechanism includes a groove, a rotating shaft, and a V-shaped rod. The groove is evenly opened on the top of the outer side of the tapered insert along the circumference, and the groove is connected to the inner top of the slide. A rotating shaft is rotatably installed between both sides of the groove, and a V-shaped rod is fixedly installed on each rotating shaft.
[0013] Preferably, the outer side of the V-shaped rod away from the groove is uniformly provided with anti-slip texture, and the anti-slip texture is parallel to the horizontal plane.
[0014] Preferably, a through hole is provided between the hidden groove and the sliding groove, and the inner diameter of the through hole is larger than the diameter of the bolt thread.
[0015] Preferably, the bolt has a cross-shaped groove on its top and an arc-shaped rounded corner on the outer side of the bolt top.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This utility model features a tapered insert at the bottom of the rubber speed bump, which is fixed in an installation hole on the road surface. The tapered insert has a groove at its inner bottom and a hidden groove at its top. A nut is vertically slidably installed inside the groove. A spring is located between the bottom of the nut and the bottom of the groove. When the rubber speed bump is fixed with a bolt, the nut moves upward and the spring is stretched.

[0031] Example 1
[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a highway speed bump, including a rubber speed bump 1 and mounting grooves 101 evenly opened on both sides of the rubber speed bump 1. Both sides of the bottom of the rubber speed bump 1 are vertically provided with tapered inserts 2 below the mounting grooves 101. The inner bottom of the tapered inserts 2 is vertically provided with sliding grooves 3, and the inner top of the tapered inserts 2 is provided with hidden grooves 4. The sliding grooves 3 and the hidden grooves 4 are connected.
[0033] A nut 5 is vertically slidably installed inside the slide groove 3, and a spring 6 is fixedly installed between the bottom end of the nut 5 and the inner bottom of the slide groove 3.
[0034] A bolt 7 is vertically installed inside the mounting groove 101, and the bolt 7 extends through the hidden groove 4 into the interior of the slide groove 3 and is threadedly connected to the nut 5.
[0035] A reinforcing mechanism 8 is provided on the top of the outer side of the tapered insert 2.
[0036] During installation, the tapered rod 2 is first inserted into the pre-set installation hole on the road surface. The bolt 7 is then inserted into the hidden groove 4 through the installation groove 101, so that the bolt 7 extends into the sliding groove 3 and is threadedly connected to the nut 5. When the bolt 7 is tightened, the nut 5 slides vertically upward along the sliding groove 3, while stretching the spring 6 at the bottom, until the rubber speed bump 1 is firmly pressed onto the road surface and fixed. At the same time, the reinforcement mechanism 8 on the outside of the tapered rod 2 can further enhance the overall stability during the installation process, preventing the tapered rod 2 from loosening or being pulled out. When the rubber speed bump 1 cracks and falls off due to aging, the fixing relationship between the bolt 7 and the rubber speed bump 1 is released. The stretched spring 6 releases its elastic potential energy, pulling the nut 5 downward along the sliding groove 3 to reset. During the downward movement of the nut 5, the bolt 7 moves downward synchronously. Finally, the head of the bolt 7 is pulled into the hidden groove 4, achieving complete concealment of the bolt 7 and preventing it from protruding from the road surface and forming a road obstacle.
[0037] Example 2
[0038] The following section provides a further description of the scheme in Example 1, focusing on its specific working method. See the description below for details:
[0039] like Figure 3 As shown, in a preferred embodiment, based on the above method, the inner diameter of the hidden groove 4 is larger than the diameter of the bolt head 7, and the depth of the hidden groove 4 is larger than the thickness of the bolt head 7.
[0040] The structural design provides sufficient space for the head of bolt 7. When spring 6 pulls bolt 7 down, the head of bolt 7 can be completely sunk into the hidden groove 4, ensuring that the head of bolt 7 is not exposed on the road surface and completely eliminating the safety hazard of "bolt protrusion".
[0041] like Figure 3 As shown, in a preferred embodiment, based on the above method, the outer side of the tapered insert 2 is further provided with anti-slip grooves evenly distributed in the vertical direction, and the anti-slip grooves are circular in shape.
[0042] The circular anti-slip groove can increase the contact friction between the tapered rod 2 and the inner wall of the mounting hole on the road surface, reduce the shaking or displacement of the tapered rod 2 when the vehicle runs over the speed bump, enhance its connection stability with the road surface, and prevent the rod from loosening.
[0043] like Figure 4As shown, in a preferred embodiment, based on the above method, the reinforcement mechanism 8 further includes a groove 801, a rotating shaft 802 and a V-shaped rod 803. The groove 801 is evenly opened on the top of the outer side of the tapered insert 2 in the circumferential direction, and the groove 801 is connected to the inner top of the slide groove 3. The rotating shaft 802 is rotatably installed between both sides of the groove 801, and the V-shaped rod 803 is fixedly installed on the rotating shaft 802.
[0044] When bolt 7 is tightened and nut 5 moves upward, the top of nut 5 will push V-shaped rod 803 to rotate around shaft 802, causing V-shaped rod 803 to rotate out of groove 801. Its end is stuck on the inner wall of the road mounting hole. Through the mechanical engagement between V-shaped rod 803 and the inner wall of mounting hole, a "reverse pull" is formed, preventing tapered rod 2 from being pulled upward when run over by a vehicle, significantly improving the installation firmness.
[0045] like Figure 4 As shown, in a preferred embodiment, based on the above method, the outer side of the V-shaped rod 803 away from the slide groove 3 is evenly provided with anti-slip texture, and the anti-slip texture is parallel to the horizontal plane.
[0046] The horizontal anti-slip texture can increase the friction between the V-shaped rod 803 and the inner wall of the mounting hole, preventing the V-shaped rod 803 from sliding along the inner wall under the impact force generated by the vehicle running over it, ensuring its "engagement" state is stable, and further strengthening the pull-out resistance of the reinforcement mechanism 8.
[0047] like Figure 3 As shown, in a preferred embodiment, based on the above method, a through hole is further provided between the hidden groove 4 and the sliding groove 3, and the inner diameter of the through hole is larger than the diameter of the bolt 7.
[0048] The through hole provides space for the bolt 7 to move up and down, ensuring that the bolt 7 can move freely up and down along the slide groove 3 with the nut 5, moving upward when tightened and downward when loosened, avoiding jamming between the bolt and the inner wall of the through hole, and ensuring the smooth implementation of the "automatic bolt hiding" function.
[0049] like Figure 3 As shown, in a preferred embodiment, based on the above method, the top of the bolt 7 is provided with a cross-shaped groove, and the outer side of the top of the bolt 7 is provided with an arc-shaped rounded corner.
[0050] The cross-shaped groove makes it easy to tighten the bolt 7 with tools such as Phillips screwdrivers, improving installation efficiency; the rounded corners can eliminate the sharp edges of the bolt 7 head, avoiding scratches to operators during installation, and at the same time preventing the bolt 7 from causing wear to the road surface or vehicle tires when it is hidden in the concealed groove 4.
[0051] Example 3
[0052] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.
[0053] During installation, first insert the tapered rod 2 into the pre-set mounting hole on the road surface. Then, insert the bolt 7 through the mounting groove 101 into the hidden groove 4, allowing the bolt 7 to extend into the sliding groove 3 and connect with the nut 5 via threads. When tightening the bolt 7, the nut 5 slides vertically upward along the sliding groove 3, simultaneously stretching the bottom spring 6 until the rubber speed bump 1 is firmly pressed onto the road surface to complete the fixation. At the same time, when the bolt 7 is tightened and the nut 5 moves upward, the top of the nut 5 will push the V-shaped rod 803 to rotate around the pivot 802, causing the V-shaped rod 803 to rotate out of the groove 801, with its end locking onto the road surface for installation. On the inner wall of the hole, the V-shaped rod 803 mechanically engages with the inner wall of the mounting hole to form a "reverse pull" to prevent the tapered rod 2 from being pulled upward when it is run over by a vehicle, which significantly improves the installation firmness. When the rubber speed bump 1 cracks and falls off due to aging, the fixed relationship between the bolt 7 and the rubber speed bump 1 is released. The stretched spring 6 releases its elastic potential energy and pulls the nut 5 down along the slide groove 3 to reset. During the downward movement of the nut 5, the bolt 7 moves down synchronously. Finally, the head of the bolt 7 is pulled into the hidden groove 4, realizing the complete concealment of the bolt 7 and preventing it from protruding from the road surface and forming a road obstacle.
[0054] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
