[0002] Speed ​​bumps, also called deceleration ridges, are traffic facilities installed on roads to slow down passing vehicles. They are generally strip-shaped but also dot-shaped. They are mainly made of metal but also rubber. They are usually yellow and black to attract visual attention. They make the road surface slightly arched to achieve the purpose of slowing down vehicles. They are usually set up at highway intersections, industrial and mining enterprises, schools, residential areas and other sections where vehicles need to slow down and sections that are prone to traffic accidents.

[0028] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0029] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0030] like Figure 1-6 As shown, this embodiment provides a deceleration device for municipal engineering, including a mounting plate 1 and a deceleration belt body 2;

[0031] The four corners of the mounting plate 1 are penetrated with mounting holes 13, so that the mounting plate 1 can be fixed to the ground by four bolts. The mounting plate 1 is fixed with slide plates 4 on both sides facing the oncoming vehicle and the back of the oncoming vehicle. The mounting plate 1, the slide plates 4, and the speed bump body 2 are parallel. The speed bump body 2 is fixed with sliding sleeves 3 on both sides facing the oncoming vehicle and the back of the oncoming vehicle. The cross section of the sliding sleeve 3 is a C-shaped structure, and the two ends of the sliding sleeve 3 are open. The sliding sleeves 3 on both sides are respectively slidably matched with the slide plates 4 on both sides, that is, the slide plates 4 are embedded in the openings of the C-shaped structure, so that the sliding sleeves 3 can slide back and forth along the slide plates 4, that is, the speed bump body 2 can move back and forth along the mounting plate 1. It is worth noting that the bottom surface of the speed bump body 2 is in contact with the top surface of the mounting plate 1, and the bottom surface of the speed bump body 2 and the top surface of the mounting plate 1 are both smooth surfaces.

[0032] Through holes are provided at both ends of the slide plate 4, and the length of the slide plate 4 is longer than the sleeve 3, so that both ends of the slide plate 4 can be exposed to the outside at the same time, that is, the through holes at both ends of the slide plate 4 can be exposed to the outside at the same time, and the two slide plates 4 correspond to four through holes, and limiting columns 501 are inserted in the four through holes. The limiting columns 501 can limit the sleeve 3 to prevent the sleeve 3 from continuing to slide away from the slide plate 4.

[0033] Based on the above structure, when installing the speed belt body 2, it is necessary to first fix the mounting plate 1 to the ground with bolts, and then slide the sleeve 3 into one end of the slide plate 4, so that the sleeves 3 on both sides are respectively slidably matched with the slide plates 4 on both sides, so that the speed belt body 2 can slide back and forth along the mounting plate 1. After sliding the speed belt body 2 to a suitable position, insert the limit columns 501 into the four through holes to complete the installation of the speed belt body 2.

[0034] When the speed bump body 2 is damaged and needs to be replaced, the limiting column 501 can be taken out of the through hole, and then the speed bump body 2 can be slid and removed without removing the mounting plate 1. When replacing a new speed bump body, the new speed bump body can be directly slid and installed. Installation or removal is very convenient, and the mounting plate 1 can be avoided from being removed from the ground.

[0035] In this embodiment, Figure 3 As shown, a limiting platform 505 is fixed at one end of the limiting column 501, and the size of the limiting platform 505 is larger than the through hole, that is, the limiting platform 505 cannot pass through the through hole. A hanging hole 504 is provided on the side wall of the other end of the limiting column 501, and the hanging hole 504 is used to install a fixed lock. For example, when the limiting column 501 passes through the through hole from bottom to top, the limiting platform 505 can play a limiting role to prevent the limiting column 501 from passing through the through hole. After the hanging hole 504 of the limiting column 501 passes through the through hole, the movable end of the fixed lock can be passed through the hanging hole 504 and locked. The fixed lock and the limiting platform 505 work together to prevent the limiting column 501 from detaching from the through hole, thereby locking the limiting column 501. At the same time, it can also prevent the speed bump body 2 from being stolen.

[0036] A pull ring 12 is fixed to one end of the limiting column 501 away from the limiting platform 505. The outer wall of the pull ring 12 may be provided with anti-slip grooves, and the setting of the pull ring 12 is convenient for manual operation by staff.

[0037] In this embodiment, a groove 502 is provided on the side wall of the limiting column 501, and a limiting rod 503 is rotatably connected to the inner wall of the groove 502. When the limiting column 501 passes through the through hole from bottom to top, the limiting rod 503 is pressed into the groove 502. After the limiting rod 503 completely passes through the through hole, the limiting rod 503 can be swung out of the groove 502, and then the limiting column 501 is moved downward so that the bottom end of the limiting rod 503 abuts against the slide plate 4. At this time, the limiting column 501 cannot automatically fall off the through hole. This method can also limit the limiting rod 503 when the fixed lock is not used, and the operation is simpler.

[0038] In this embodiment, a sleeve 6 is fixed inside the speed bump body 2, a first end of the sleeve 6 extends to the upper surface of the speed bump body 2, a second end of the sleeve 6 extends to the bottom surface of the speed bump body 2, and a warning light 7 is arranged inside the sleeve 6. In bad weather conditions such as at night, the warning light 7 can serve as a warning, so that vehicles can observe and notice the speed bump body 2 and slow down in advance to avoid accidents.

[0039] A transparent plate 11 is fixed to the first end of the sleeve 6. The transparent plate 11 can provide protection for the warning light 7 to prevent the warning light 7 from being damaged.

[0040] The bottom surface of the speed bump body 2 is provided with a mounting groove 16, the second end of the sleeve 6 extends into the mounting groove 16, and a sealing plate 8 is provided at the opening of the mounting groove 16. The arrangement of the mounting groove 16 provides a large space for the staff to install the warning light 7, and the sealing plate 8 can play a role in sealing and protecting the warning light 7.

[0041] The bottom end of the sealing plate 8 is fixed with a convex strip 9, and the mounting plate 1 is provided with a slot 10 adapted to the convex strip 9, the convex strip 9 is embedded in the slot 10, and the convex strip 9, the slot 10, and the mounting plate 1 are parallel. The convex strip 9 can enhance the stability of the sealing plate 8 and the mounting plate 1, and further enhance the stability of the speed bump body 2 and the mounting plate 1.

[0042] Please refer again Figure 1 In this embodiment, a rubber pad 14 is fixed on the outer wall of the speed bump body 2. The rubber pad 14 can form a flexible connection between the speed bump body 2 and the wheel to prevent the wheel from being damaged, and can also improve the shock absorption of the speed bump body 2.

[0043] The outer wall of the speed bump body 2 is provided with a buckle groove 15, and the inner wall of the buckle groove 15 is provided with anti-slip grooves. By providing the buckle groove 15 on the outer wall of the speed bump body 2, it is convenient for workers to hold the speed bump body 2 when installing and removing it, which can improve the work efficiency of users.

[0044] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.
