DETAILED DESCRIPTION

[0029] The utility model is now described in further detail with reference to the accompanying drawings.

[0030] See also Figure 1-4 As shown, in this embodiment, a speed bump for municipal engineering is provided, including a speed reduction device 1; the speed reduction device 1 is composed of a speed bump 4 and a mounting box 2, the mounting box 2 is mounted on the upper side of a base 11, mounting plates 5 are mounted on both sides of the upper end of the mounting box 2, a water seepage hole 7 is arranged at the bottom end of the mounting box 2, the speed bump 4 is slidably mounted inside the mounting box 2, a lifting mechanism 9 is installed between the bottom end of the speed bump 4 and the upper end of the mounting box 2, the lifting mechanism 9 is composed of an insertion rod 15 and an insertion tube 18, the insertion tube 18 is mounted at the bottom end of the mounting box 2, the upper end of the insertion rod 15 is mounted at the upper end position of the speed bump 4, the bottom end of the insertion rod 15 is inserted into the insertion tube 18, a spring 14 is installed inside the insertion tube 18 at the bottom end position of the insertion rod 15, and an air outlet 17 is arranged at the bottom end position of the insertion tube 18.

[0031] The application of one aspect of this embodiment is as follows: when the deceleration device 1 is installed, the installation box 2 is installed on the upper side of the base 11. When in use, when the vehicle slowly passes through the deceleration device 1, the speed bump 4 will be slowly subjected to force. At this time, the insertion rod 15 will slowly enter the inside of the insertion tube 18, and the air inside the insertion tube 18 will be evenly discharged through the air outlet 17, so that the speed bump 4 can slowly move downward and shrink into the inside of the installation box 2. At this time, the slowly moving vehicle will not feel bumpy. When the vehicle passes quickly, the speed bump 4 will be quickly subjected to force. When the insertion rod 15 is quickly inserted into the inside of the socket, due to the limited number of air outlets from the air outlet 17, the internal pressure of the insertion tube 18 increases, thereby applying a reaction force to the insertion rod 15, causing the speed bump 4 to stop moving downward, thereby forming a barrier to the fast-moving vehicle. After the vehicle has completely passed the deceleration device 1, the spring 14 inside the insertion barrel will drive the insertion rod 15 and the speed bump 4 to reset.

[0032] In this embodiment, an anti-skid strip 6 is arranged at the upper end of the speed bump 4, and the bottom end of the anti-skid strip 6 is integrated with the speed bump 4. The anti-skid strip 6 is arranged to increase the friction on the upper side of the speed bump 4 to prevent the vehicle from slipping during climbing.

[0033] In this embodiment, side support plates 10 are installed between the upper end of the insertion rod 15 and the inner bottom end of the speed bump 4, and between the bottom end of the insertion tube 18 and the inner bottom end of the installation box 2. The side support plates 10 are provided to fix the upper end of the insertion rod 15 and the inner bottom end of the speed bump 4, and between the bottom end of the insertion tube 18 and the inner bottom end of the installation box 2, so that the installation between the upper end of the insertion rod 15 and the inner bottom end of the speed bump 4, and between the bottom end of the insertion tube 18 and the inner bottom end of the installation box 2 is more stable.

[0034] In this embodiment, a limit plate 16 is installed at the bottom end of the insertion rod 15 at the bottom end of the inner section of the insertion tube 18, and a sealing ring 13 is installed on the outer side of the limit plate 16. The setting of the limit plate 16 is used to limit the range of movement of the insertion rod 15 to prevent the insertion rod 15 from detaching from the insertion tube 18 during use. The setting of the sealing ring 13 is used to increase the sealing between the insertion rod 15 and the insertion tube 18.

[0035] In this embodiment, a damping sleeve 12 is installed at the upper end of the insert cylinder 18 at the outer side of the insert rod 15. The damping sleeve 12 is slidably installed at the outer side of the insert rod 15. The damping sleeve 12 is provided to increase the resistance between the insert rod 15 and the insert cylinder 18 to avoid the speed bump 4 from shaking during use.

[0036] In this embodiment, baffles 8 are arranged on both sides of the interior of the installation box 2, and the baffles 8 are welded on both sides of the interior of the installation box 2. The baffles 8 are arranged to limit the distance that the speed bump 4 moves up and down, so as to prevent the speed bump 4 from rising and detaching from the installation box 2 and the speed bump 4 from sinking into the interior of the installation box 2.

[0037] In this embodiment, a corrosion-resistant layer 3 is provided on the outer side of the installation box 2 and the speed bump 4. The corrosion-resistant layer is set as a chrome-plated layer. The chrome-plated layer used in the corrosion-resistant layer 3 has strong corrosion resistance, which can reduce the corrosion of the installation box 2 and the speed bump 4 during use and extend the service life of the speed bump 4 and the installation box 2.
