Description

Technical Field

[0001] The utility model relates to the technical field of speed bumps, and more specifically, to a combined road speed bump. Background Art

[0002] During the municipal road construction process, it is necessary to install speed bumps on the surface of some road sections. Speed ​​bumps are traffic facilities installed on the road to slow down passing vehicles. They are often used in places with large crowds such as schools, hospitals and supermarkets. They can also urge drivers to slow down, thereby improving the safety of pedestrians on the road.

[0003] When a vehicle passes through a speed bump, the vehicle body will vibrate, which will still cause damage to the vehicle body. The existing speed bumps cannot adjust the height of the speed bumps according to the vehicle speed to protect the vehicle that has slowed down. In view of this, a combined road speed bump is provided. Utility Model Content

[0004] (1) Technical issues to be solved

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a combined road speed bump, which has the characteristic of protecting vehicles with a slower speed.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides a combined road speed bump, including a shell, the surface of the shell is provided with a step, the upper surface of the step is slidably connected with a plurality of first sliding bars, the upper ends of the plurality of first sliding bars are fixedly connected with a support plate, the upper surface of the support plate is fixedly connected with a speed bump body, the lower surface of the support plate is provided with a groove, the inner wall of the groove is fixedly connected with two second sliding bars, the surfaces of the two second sliding bars are slidably connected with sliding blocks, the surfaces of the two second sliding bars are respectively sleeved with springs, the lower surface of the sliding block is fixedly connected with a fixing plate, the surface of the fixing plate is penetrated with a rotating shaft, the surface of the rotating shaft is rotatably connected with a support rod, the lower end of the support rod is rotatably connected with another rotating shaft, another surface of the rotating shaft is rotatably connected with another fixing plate, the other fixing plate is fixedly connected to the bottom of the inner wall of the shell, and there are two groups of support rods, which are symmetrically arranged on the inner wall of the shell.

[0008] When a combined road speed bump of the present technical solution is used, a support plate and a first slide bar are provided to facilitate the up and down movement of the speed bump body. Since the lifting and lowering direction of the speed bump body is vertical, and the impact direction generated by the wheels when the vehicle is traveling is oblique, when a vehicle passes by quickly, the speed bump body cannot drop quickly, which will cause vibration to the vehicle passing at high speed. When a vehicle passes slowly, the weight of the vehicle drives the speed bump body to drop, thereby avoiding large vibrations caused to the vehicle and protecting the vehicle.

[0009] Furthermore, a soft protective strip is fixedly connected to the upper surface of the shell, and the soft protective strip is overlapped on the surface of the speed reduction belt body.

[0010] Furthermore, the surface of the soft protective belt and the upper surface of the shell are both provided with anti-slip patterns, and the anti-slip patterns are made of reflective material.

[0011] Furthermore, a connecting block is fixedly connected to the side surface of the shell.

[0012] Furthermore, a connection groove is provided on the lower surface of the shell, and the connection groove cooperates with the connection block.

[0013] Furthermore, the speed bump body is made of rubber.

[0014] (3) Beneficial effects

[0015] In summary, the utility model has the following beneficial effects:

[0016] 1. This combined road speed bump is provided with a support plate and a first slide bar, so that the speed bump body can be moved up and down. Since the lifting direction of the speed bump body is vertical, and the impact direction of the wheels when the vehicle is running is oblique, when the vehicle passes by quickly, the speed bump body cannot be quickly lowered, which will cause vibration to the vehicle passing by at high speed. When the vehicle passes slowly, the weight of the vehicle drives the speed bump body to lower, thereby avoiding large vibration caused by the vehicle and protecting the vehicle.

[0017] 2. This combined road speed bump is convenient to drive the slider to slide on the surface of the second slide rod by setting a spring. Under the action of the fixed plate and the rotating shaft, it is convenient to drive the support rod to adjust the angle, so that the speed bump body can be automatically reset. At the same time, the descending speed of the speed bump body can be buffered. By setting steps, it is convenient to support the support plate and the speed bump body.

There are two groups of support rods 12, which are symmetrically arranged on the inner wall of the shell 1. By arranging the support plate 4 and the first slide bar 3, it is convenient to make the speed reduction belt body 5 move up and down. Since the lifting direction of the speed reduction belt body 5 is vertical up and down, and the impact direction of the wheels when the vehicle is running is oblique, when the vehicle passes by quickly, the speed reduction belt body 5 cannot drop quickly, which will cause vibration to the vehicle passing at high speed. When the vehicle passes slowly, the weight of the vehicle drives the speed reduction belt body 5 to drop, thereby avoiding large vibration of the vehicle and protecting the vehicle.

[0028] Specifically, a soft protective strip 13 is fixedly connected to the upper surface of the shell 1 , and the soft protective strip 13 is overlapped on the surface of the speed reduction belt body 5 .

[0029] By adopting the above technical solution and providing the soft protective strip 13, the gap generated when the speed reduction belt body 5 descends can be filled to protect the tire.

[0030] Specifically, the surface of the soft protective belt 13 and the upper surface of the shell 1 are both provided with anti-skid patterns 14 , and the anti-skid patterns 14 are made of reflective material.

[0031] By adopting the above technical solution and providing the anti-slip grooves 14 , the friction between the upper surface of the housing 1 and the surface of the soft protection belt 13 is increased.

[0032] Specifically, a connecting block 15 is fixedly connected to the side of the shell 1, and a connecting groove 16 is opened on the lower surface of the shell 1. The connecting groove 16 matches the connecting block 15, and the speed reduction belt body 5 is made of rubber material.

[0033] By adopting the above technical solution and providing the connecting block 15 and the connecting groove 16 , it is convenient to connect the adjacent housings 1 .

[0034] The working principle of the utility model is as follows: when in use, the shell 1 is embedded in the road surface, so that the two adjacent shells 1 are clamped by the connecting block 15 and the connecting groove 16. Under the action of the first slide bar 3, the support plate 4 and the speed reduction belt body 5 are moved up and down. When the vehicle passes by quickly, the speed reduction belt body 5 cannot drop quickly, which will cause vibration to the vehicle passing at high speed, thereby achieving the deceleration effect. When the vehicle passes slowly, the weight of the vehicle drives the speed reduction belt body 5 to drop, so that the slider 8 slides on the surface of the second slide bar 7, and under the action of the fixed plate 10 and the rotating shaft 11, the support rod 12 is driven to adjust the angle, so that the support plate 4 and the speed reduction belt body 5 slowly drop, avoiding large vibration caused by the vehicle and protecting the vehicle. At the same time, under the action of the soft protective strip 13, the gap generated when the speed reduction belt body 5 drops is filled to protect the tire. Under the action of the spring 9, the slider 8 is driven to slide on the surface of the second slide bar 7, and the support rod 12 is driven to adjust the angle through the fixed plate 10 and the rotating shaft 11, so that the speed reduction belt body 5 is automatically reset.
