Description

Technical Field

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

[0002] Speed ​​bumps, also known as speed ridges, are traffic facilities installed on highways to slow down passing vehicles. They are usually yellow and black striped to attract visual attention and slightly bulge the road surface to achieve the purpose of slowing down vehicles. Speed ​​bumps are usually installed on road sections with high pedestrian traffic, but when school is over or people are resting in places such as shopping malls, the pedestrian traffic is low, and the speed bumps are not very effective at this time. Therefore, a retractable speed bump is needed, which can be deployed when the pedestrian traffic is high and retracted when the pedestrian traffic is low to ensure smooth traffic.

[0003] The existing patent with authorization announcement number "CN214328593U" discloses a retractable speed bump for toll roads, including several speed bump bodies, and also includes: a receiving box, set on the roadside, containing space to accommodate the speed bump bodies; several limiting holes, embedded in the road surface corresponding to the speed bump; and limiting posts, connected to the speed bump bodies by a telescopic component, and matching the specifications of the limiting holes. The speed bump of this utility model can be retracted and extended freely, and the road surface will not produce obvious unevenness after being retracted, reducing the bumps of passing vehicles, truly playing the ideal role of a retractable speed bump, and the structural stability of the speed bump remains high when it is in use;

[0004] However, this device has the following shortcomings:

[0005] 1. When using the above device, the speed bump still needs to be manually unfolded, which is quite troublesome and reduces the ease of use of the device;

[0006] 2. Speed ​​bumps have poor visibility at night, making it difficult for vehicles to see them and slow down in advance, which increases the danger of crossing speed bumps. The above-mentioned devices also fail to improve the visibility of speed bumps, thus reducing the safety of using speed bumps. Utility Model Content

[0007] The purpose of this invention is to provide a retractable speed bump to solve the existing problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a telescopic speed bump, comprising a base, an adjustment groove inside the base, a storage groove at the top of the base, hydraulic cylinders at both ends and the middle of the bottom of the adjustment groove, a movable plate at the output ends of three sets of hydraulic cylinders, a connecting block at the top of the movable plate, a telescopic plate at the top of the connecting block, sliding grooves on both sides of the inner ends of the storage groove, sliders slidably connected to the inner sides of four sets of sliding grooves, a speed bump sleeved on one end of two sets of sliders on the same side, the two sides of the telescopic plate rotatably connected to the two sets of speed bumps, an electric contact A on one side of the top of the movable plate, an electric contact B cooperating with the electric contact A on one side of the top of the adjustment groove, multiple mounting grooves on the top of the telescopic plate, and indicator lights at the bottom of the inner sides of the multiple mounting grooves.

[0009] Preferably, a through hole is provided in the middle of the bottom inner side of the storage groove to cooperate with the connecting block, so as to guide the connecting block.

[0010] Preferably, guide grooves are provided on both sides inside the adjustment groove, and guide blocks that cooperate with the guide grooves are provided on both sides of the movable plate, which improves the stability of the telescopic plate when it is unfolded and stored.

[0011] Preferably, a protective cover is provided on the top of the inner side of the mounting groove, and the protective cover is made of transparent material, which can protect the indicator light without affecting its luminous effect.

[0012] Preferably, the output end of the hydraulic cylinder is provided with a mounting plate, and the mounting plate is fixedly connected to the movable plate to connect the hydraulic cylinder and the movable plate, thereby improving the connection stability.

[0013] Preferably, the bottom of the adjusting groove is provided with fixing grooves at both ends and the middle, and the three sets of hydraulic cylinders are located inside the fixing grooves, which can provide installation space for the hydraulic cylinders.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the telescopic speed bump;

[0015] 1. Through the cooperation of hydraulic cylinders, movable plates, telescopic plates, connecting blocks, speed reduction plates, sliders, and slides, the device can control the telescopic plates to move upward and unfold during use, so that the three plates unfold into a trapezoidal speed bump to slow down vehicles. When the speed bump is not in use, the telescopic plates can be controlled to move downward and retract, so that the three plates can be retracted to keep them at the same level as the ground to prevent them from affecting vehicle driving. The speed bump is easy to control, requires no manual adjustment, and can be extended and retracted according to the flow of people, making it more flexible to use.

[0016] 2. Through the cooperation between the movable plate, electrical contact A, electrical contact B, indicator light and mounting slot, the device can automatically activate the indicator light when the speed bump is unfolded to improve the visibility of the speed bump, making it easier for passing vehicles to see the speed bump and slow down in advance, thus improving the safety of using the speed bump.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4The present invention provides an embodiment of a telescopic speed bump, comprising a base 1, an adjustment groove 2 inside the base 1, and a storage groove 12 on the top of the base 1. Hydraulic cylinders 3 are installed at both ends and the middle of the bottom of the adjustment groove 2. A movable plate 4 is installed at the output ends of the three sets of hydraulic cylinders 3. A connecting block 8 is installed on the top of the movable plate 4. A through hole is provided in the middle of the bottom of the inner side of the storage groove 12 to guide the connecting block 8, allowing it to slide along the inner side of the through hole. The top of the connecting block 8... The unit is equipped with a telescopic plate 7. Slide grooves 14 are provided on both sides of the inner end of the storage groove 12. Sliding sliders 13 are slidably connected to the inner side of the four sets of slide grooves 14. A speed reduction plate 9 is sleeved on one end of two sets of sliders 13 on the same side. The two sides of the telescopic plate 7 are rotatably connected to the two sets of speed reduction plates 9. An electric contact block A5 is provided on one side of the top of the movable plate 4. An electric contact block B6 that cooperates with the electric contact block A5 is provided on one side of the top of the inner side of the adjustment groove 2. Multiple sets of mounting grooves 11 are provided on the top of the telescopic plate 7. An indicator light 10 is provided at the bottom of the inner side of the multiple sets of mounting grooves 11.

[0024] Furthermore, guide grooves are provided on both sides inside the adjustment groove 2, and guide blocks that cooperate with the guide grooves are provided on both sides of the movable plate 4, which can guide the movable plate 4 and improve the stability of the telescopic plate 7 when it is unfolded and stored.

[0025] Furthermore, a protective cover is provided on the top of the inner side of the mounting slot 11. The protective cover is made of transparent material, which can protect the indicator light 10 without affecting its lighting effect.

[0026] Furthermore, the output end of the hydraulic cylinder 3 is provided with a mounting plate, and the mounting plate is fixedly connected to the movable plate 4 for connecting the hydraulic cylinder 3 and the movable plate 4, thereby improving the connection stability. The bottom of the adjusting groove 2 is provided with fixing grooves at both ends and the middle, and the three sets of hydraulic cylinders 3 are located inside the fixing grooves, which can provide installation space for the hydraulic cylinders 3.

[0027] Working principle: When speed bumps are needed due to high pedestrian traffic, the device can activate three sets of hydraulic cylinders 3. The three sets of hydraulic cylinders 3 can push the connecting block 8 upward, and then the connecting block 8 can drive the telescopic plate 7, so that the telescopic plate 7 can extend out from the storage groove 12. At this time, the telescopic plate 7 is rotatably connected with the two sets of speed plates 9, which can pull the two sets of speed plates 9 to tilt along the guide of the slide groove 14, so that the speed plates 9 and the telescopic plate 7 can unfold to form a trapezoidal speed bump, which prompts passing vehicles to slow down.

[0028] When the telescopic plate 7 is unfolded, the connecting block 8 can drive the movable plate 4 to move upward. The movable plate 4 can simultaneously drive the electric contact block A5 to move upward. When the telescopic plate 7 is unfolded, the electric contact block A5 can contact the electric contact block B6, thereby automatically activating the indicator light 10 to increase the visibility of the speed bump at night and to remind the vehicle to slow down in advance.

[0029] When there is little traffic on the road, the hydraulic cylinder 3 can be activated to move the telescopic plate 7 down into the storage slot 12. At the same time, the deceleration plate 9 can also be retracted into the storage slot 12. At this time, the deceleration plate 9 and the telescopic plate 7 can be kept at the same level as the road surface, so that vehicles can pass smoothly. At the same time, the electric contact block A5 can be separated from the electric contact block B6 to turn off the indicator light 10.
