Description

Technical Field

[0001] This utility model relates to the field of speed bump technology, and more specifically to a road buffer 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 generally strip-shaped, but some are dotted, and are primarily made of rubber, though some are metal. They are typically yellow and black striped to attract visual attention, creating a slight bulge in the road surface to slow vehicles down. They are usually installed at highway intersections, industrial and mining enterprises, school entrances, residential area entrances, and other sections of road where vehicles need to slow down or where traffic accidents are prone to occur. They serve to buffer and slow down traffic, improving safety at intersections. Currently, speed bumps are usually installed by first drilling holes in the road surface and then fixing them to the road surface with steel nails or expansion bolts. When speed bumps are subjected to long-term wear from vehicles and are further weakened by rain and moisture, their structural strength is reduced, leading to damage and requiring replacement.

[0003] Most speed bumps currently used on roads are made up of multiple sections spliced ​​together. When one section of a speed bump is damaged and needs to be replaced, workers need to remove the steel nails or expansion bolts from the holes drilled in the ground, then drill new holes in the ground, and then fix the replacement speed bump to the road surface with steel nails or expansion bolts. This replacement method is quite cumbersome, requiring repeated drilling in the ground, which not only damages the integrity of the original road surface, but may also cause safety hazards due to multiple constructions, increasing maintenance costs and time costs. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a road buffer speed bump to solve the problems in the background art.

[0005] This utility model provides the following technical solution: a road buffer speed bump, including a base plate and a speed bump body, and also including a stop block. A connecting component is provided at the bottom of the speed bump body, and the stop block is fixedly installed on the connecting component and located below the speed bump body. An adjusting component that drives the connecting component to rotate is provided inside the speed bump body. Several sets of limiting components for limiting the stop block are provided at the top of the base plate. The several sets of limiting components are arranged in a row at equal intervals. The limiting component includes a connecting hole, a limiting hole, a limiting block, a contact block, and several round holes. The connecting hole is opened at the top of the base plate, the limiting hole is opened at the bottom of the connecting hole, the limiting block is fixedly installed in the limiting hole, the several round holes are opened in a ring at equal intervals at the top of the base plate, and the contact block is fixedly installed in the limiting hole.

[0006] Furthermore, the connecting assembly includes a fixing hole, a fixing block, and a rotating rod. The fixing hole is opened at the top of the speed bump body and extends through to the bottom of the speed bump body. The fixing block is fixedly installed in the fixing hole. The rotating rod is rotatably installed in the fixing hole, with one end of the rotating rod extending to the outside of the fixing hole. The fixing block is located above the rotating rod, and the stop block is fixedly installed on the surface of the rotating rod and located below the speed bump body.

[0007] Furthermore, the adjustment assembly includes a support rod, a torsion spring, and a connecting block. The support rod, torsion spring, and connecting block are all located inside the fixing hole. One end of the support rod passes through the fixing block and is fixedly connected to the rotating rod. The support rod is rotatably connected to the fixing block. The connecting block is fixedly connected to the other end of the support rod and is in close contact with the inner wall of the fixing hole. The torsion spring is sleeved on the support rod. One end of the torsion spring is fixedly connected to the fixing block, and the other end is fixedly connected to the connecting block.

[0008] Furthermore, several connecting rods are fixedly installed in a ring at equal intervals at the bottom of the speed bump body.

[0009] Furthermore, reflective strips are fixedly installed on the inclined surfaces on both sides of the speed bump body.

[0010] Furthermore, several mounting holes are provided on the top of the base plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model involves rotating a connecting block, which in turn drives a support rod to rotate. This causes a torsion spring to deform, and the support rod drives a rotating rod and a stop block to rotate. The operator aligns the stop block and rotating rod with the connecting hole and places the speed bump body on top of the base plate. When the top of the base plate contacts the bottom of the speed bump body, the bottom of the rotating rod contacts the bottom of the limiting hole, and the surface of the rotating rod abuts against the surface of the connecting hole. The connecting rod then enters the corresponding circular hole. At this point, the operator stops rotating the connecting block, and the torsion spring rebounds, causing the connecting block, support rod, rotating rod, and stop block to rotate synchronously in opposite directions. This causes the stop block to rotate along the limiting hole and contact the limiting block. At this point, the torsion spring can no longer rebound because its elasticity keeps the stop block abutting against the limiting block. The speed bump body is then fixedly connected to the base plate, facilitating installation and replacement of the speed bump body without the need for drilling.

[0013] 2. In this utility model, by rotating the connecting block, the connecting block drives the support rod to rotate, and the support rod drives the rotating rod and the stop block to rotate. The torsion spring deforms and moves away from the limiting block, rotating until it abuts against the contact block. At this time, the worker lifts the speed bump body upward, and the speed bump body drives the support rod, rotating rod and stop block to move upward, so that the stop block moves upward along the contact block and enters the connecting hole, and then disengages from the connecting hole, which facilitates the removal of the speed bump body from the base plate and improves the removal efficiency.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 5 The present invention will be further described below.

[0022] This utility model discloses a road buffer speed bump, including a base plate 1 and a speed bump body 2, and also includes a stop block 3. A connecting component 4 is provided at the bottom of the speed bump body 2, and the stop block 3 is fixedly installed on the connecting component 4 and located below the speed bump body 2. An adjusting component 5 is provided inside the speed bump body 2 to drive the connecting component 4 to rotate. Several sets of limiting components 6 for limiting the stop block 3 are provided at the top of the base plate 1. The several sets of limiting components 6 are arranged in a row at equal intervals. The limiting component 6 includes a connecting hole 601, a limiting hole 602, a limiting block 603, a contact block 604 and several round holes 605. The connecting hole 601 is opened at the top of the base plate 1, the limiting hole 602 is opened at the bottom of the connecting hole 601, the limiting block 603 is fixedly installed in the limiting hole 602, the several round holes 605 are arranged in a ring at equal intervals at the top of the base plate 1, and the contact block 604 is fixedly installed in the limiting hole 602.

[0023] In this implementation scheme, both the speed bump body 2 and the base plate 1 are made of steel. When in use, the base plate 1 is placed on the cleaned road surface and fixed to the road surface with steel nails. The adjusting component 5 is manually rotated to drive the connecting component 4 and the stop block 3. At this time, the worker places the speed bump body 2 on top of the base plate 1. The stop block 3 enters the limiting hole 602 along the connecting hole 601, with the bottom of the stop block 3 contacting the bottom of the limiting hole 602 and the side of the stop block 3 abutting against the side of the contact block 604. The connecting component 4 is located within the limiting hole 602 and the connecting hole 601. The worker then stops rotating the adjusting component 5, causing the connecting component 4 and the stop block 3 to rotate in the opposite direction. The stop block 3 rotates in the opposite direction along the limiting hole 602, moving away from the contact block 604 and contacting the limiting block 603, where it is stopped. The stop block 3 will then stop rotating. When block 3 rotates, the top and bottom of block 3 abut against the bottom and top of limit hole 602 respectively. At this time, the speed bump body 2 and the base plate 1 are fixed. When it is necessary to remove the speed bump body 2 from the base plate 1, the bottom of the speed bump body 2 contacts the top of the base plate 1. At this time, the operator rotates the adjusting component 5 in the opposite direction, so that the adjusting component 5 drives the connecting component 4 and block 3 to rotate in the opposite direction, so that block 3 no longer contacts limit block 603 and rotates to contact the side of contact block 604. At this time, block 3 is aligned with the connecting hole 601. At this time, the operator pulls the speed bump body 2 upward, so that the speed bump body 2 drives the adjusting component 5, connecting component 4 and block 3 to move upward, so that block 3 enters from limit hole 602 into connecting hole 601 and disengages from connecting hole 601. At this time, the base plate 1 is not connected to the speed bump body 2, which makes it convenient for the operator to replace the speed bump body 2.

[0024] Specifically, the connecting component 4 includes a fixing hole 401, a fixing block 402, and a rotating rod 403. The fixing hole 401 is located at the top of the speed bump body 2 and extends to the bottom of the speed bump body 2. The fixing block 402 is fixedly installed in the fixing hole 401. The rotating rod 403 is rotatably installed in the fixing hole 401, with one end of the rotating rod 403 extending to the outside of the fixing hole 401. The fixing block 402 is located above the rotating rod 403. The stop block 3 is fixedly installed on the surface of the rotating rod 403 and located below the speed bump body 2. The adjusting component 5 includes a support rod 501. Torsion spring 502 and connecting block 503, support rod 501, torsion spring 502 and connecting block 503 are all located in fixing hole 401. One end of support rod 501 passes through fixing block 402 and is fixedly connected to rotating rod 403. Support rod 501 is rotatably connected to fixing block 402. Connecting block 503 is fixedly connected to the other end of support rod 501. Connecting block 503 is tightly attached to the inner wall of fixing hole 401. Torsion spring 502 is sleeved on support rod 501. One end of torsion spring 502 is fixedly connected to fixing block 402 and the other end is fixedly connected to connecting block 503.

[0025] In this embodiment, when the speed bump body 2 is connected to the base plate 1, the worker inserts an auxiliary tool into the slot at the top of the connecting block 503 and rotates the connecting block 503. The connecting block 503 drives the support rod 501 to rotate, at which point the torsion spring 502 deforms. The support rod 501 drives the rotating rod 403 and the stop block 3 to rotate. The worker aligns the stop block 3 and the rotating rod 403 with the connecting hole 601 and places the speed bump body 2 on top of the base plate 1. When the top of the base plate 1 contacts the bottom of the speed bump body 2, the bottom of the rotating rod 403 contacts the bottom of the limiting hole 602, and the surface of the rotating rod 403 abuts against the surface of the connecting hole 601. The connecting rod 7 enters the corresponding circular hole 605. At this point, the worker stops rotating the connecting block 503, the torsion spring 502 rebounds, and drives the connecting block 503, the support rod 501, the rotating rod 403, and the stop block 3 to rotate synchronously in opposite directions, causing the stop block 3 to move along the limiting hole 602. The speed bump body 2 rotates and contacts the limiting block 603. At this point, the torsion spring 502 will no longer be able to rebound because the spring force of the torsion spring 502 keeps the stop block 3 abutting against the limiting block 603. At this point, the speed bump body 2 is fixedly connected to the base plate 1. When it is necessary to remove the speed bump body 2 from the base plate 1, an auxiliary tool is inserted into the slot at the top of the connecting block 503 and the connecting block 503 is rotated in the opposite direction. The connecting block 503 drives the support rod 501 to rotate, and the support rod 501 drives the rotating rod 403 and the stop block 3 to rotate. The torsion spring 502 deforms and moves the stop block 3 away from the limiting block 603 and rotates to abut against the contact block 604. At this point, the worker pulls the speed bump body 2 upward. The speed bump body 2 drives the support rod 501, the rotating rod 403 and the stop block 3 to move upward, so that the stop block 3 moves upward along the contact block 604 and enters the connecting hole 601, and then disengages from the connecting hole 601. At this point, the speed bump body 2 is removed from the base plate 1.

[0026] Specifically, the bottom of the speed bump body 2 is fixedly equipped with several connecting rods 7 in a ring shape at equal intervals.

[0027] In this embodiment, when the bottom of the speed bump body 2 contacts the top of the base plate 1, the connecting rod 7 enters the circular hole 605, thereby increasing the connection between the speed bump body 2 and the base plate 1.

[0028] Specifically, reflective strips 8 are fixedly installed on the inclined surfaces on both sides of the speed bump body 2.

[0029] In this implementation scheme, at night or in low-light environments, the reflective strip 8 can reflect the vehicle's lights, making it particularly conspicuous and enhancing the warning effect.

[0030] Specifically, the top of the base plate 1 has several mounting holes 9.

[0031] In this implementation plan, when the base plate 1 is installed on the road surface, steel nails are manually inserted through the mounting holes 9 to fix the base plate 1 to the road surface.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
