Description

Technical Field

[0001] This utility model relates to the field of armored road stud technology, and in particular to a damage-resistant flexible embedded traffic armored road stud. Background Technology

[0002] Road studs, a common type of traffic barrier, are used to guide people to travel in the correct direction and prevent speeding and traffic accidents. They are mainly used on highways and railways. Armored road studs are very effective in improving visibility guidance for drivers on highways at night. However, ordinary armored road studs have poor durability. During use, they are constantly being run over by road vehicles, and they are prone to damage over time. Removing damaged armored road studs is also quite troublesome. To improve the tire pressure resistance of armored road studs and increase the efficiency of later maintenance and replacement, a damage-resistant, flexible, embedded armored road stud is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a damage-resistant flexible embedded traffic armor stud.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A damage-resistant flexible embedded traffic armor road stud includes a road stud body. Four integrally formed protruding ribs are symmetrically arranged on both sides of the road stud body. A flexible lifting device is provided at the bottom of each protruding rib. The flexible lifting device consists of a fixing block, a fixing post, and a base. The lower end of the fixing post is fixedly installed on the base. A through hole is opened in the center of the fixing block. The fixing block slides through the through hole in the center and is inserted into the pre-opened receiving annular groove on the upper half of the circumferential surface of the fixing post. The top of the fixing block is fixedly connected to the lower surface of the protruding rib.

[0006] In a preferred embodiment, the fixing block is an integral block structure consisting of an upper block and a lower block. The through hole extends through the center of the lower block. The upper block is hollow inside and designed as a movable cavity. Notches that communicate with the movable cavity are opened on both sides of the upper block.

[0007] In a preferred embodiment, the upper end of the fixed column is embedded in the movable cavity.

[0008] In a preferred embodiment, the fixing post has a through groove cut downward along the central axis of its upper end face. The bottom of the through groove is designed as an arc-shaped groove bottom. The fixing post has a receiving annular groove and a buffer arc surface cut around its circumference. The buffer arc surface is located below the receiving annular groove.

[0009] In a preferred embodiment, the diameter of the through hole is larger than the diameter of the receiving annular groove.

[0010] In a preferred embodiment, the diameter of the through hole is smaller than the diameter of the fixed post.

[0011] In a preferred embodiment, an inner groove is pre-dug in the road for the road spike body to be inserted, and the bottom surface of the base is fixedly installed in the inner groove of the road.

[0012] The beneficial effects of this utility model are:

[0013] The armored road stud structure proposed in this solution solves the problem of poor pressure resistance and easy damage of existing armored road studs. On the one hand, this armored road stud structure can use the buffer arc surface to buffer and release tire pressure, reduce pressure impact, improve the safety of armored road studs during use, and ensure normal use. On the other hand, the armored road studs are easier to install, remove, and maintain, providing convenience for manual operation. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In this embodiment, refer to Figure 1 A damage-resistant flexible embedded traffic armor road stud includes a road stud body 1. Four integrally formed protruding ribs 2 are symmetrically arranged on both sides of the road stud body 1. A flexible lifting device 3 is provided at the bottom of each protruding rib 2. The upper surface of the protruding rib 2 is on the same arc surface as the upper surface of the road stud body 1. The protruding rib 2 can increase the contact area with concrete and prevent the road stud body 1 from moving laterally.

[0020] As attached Figure 2 Or attached Figure 3 As shown, the flexible lifting device 3 consists of a fixed block 4, a fixed column 5, and a base 6, wherein:

[0021] The lower end of the fixed post 5 is fixedly installed on the base 6. An inner groove for the road spike body 1 to be inserted is pre-dug in the road, and the bottom surface of the base 6 is fixedly installed in the inner groove of the road.

[0022] The top of the fixing block 4 is fixedly connected to the lower surface of the protruding rib 2.

[0023] The fixing block 4 is an integral block structure formed by the upper block 41 and the lower block 42. The through hole 43 passes through the through hole 43 in the center of the lower block 42. The upper block 41 is hollow inside and designed as a movable cavity 45. The upper block 41 has notches 44 on both sides that are connected to the movable cavity 45 inside.

[0024] A through groove 51 is cut downwards along the central axis of the upper end face of the fixing post 5. The bottom of the through groove 51 is designed as an arc-shaped groove bottom 52. A receiving annular groove 53 and a buffer arc surface 54 are cut around the circumference of the fixing post 5. The buffer arc surface 54 is located below the receiving annular groove 53. The fixing post 5 is made of a flexible material such as cast aluminum shell or wood. The two sides of the top of the fixing post 5 are pressed together and can automatically return to their original position after being released.

[0025] In addition, it should be noted that the diameter of the through hole 43 is larger than the diameter of the receiving annular groove 53, and the diameter of the through hole 43 is smaller than the diameter of the fixed column 5.

[0026] When installing the main body 1 of the road spike, the workers press the two sides of the upper half of the fixing post 5 together, and then the fixing block 4 of the main body 1 of the road spike can be fitted onto the fixing post 5 along the through hole 43. After the fixing post 5 is released, the upper half of the fixing post 5 separates to both sides, so that the lower block 42 is just stuck in the receiving ring groove 53, forming a stable assembly structure.

[0027] During long-term use, the tires roll over the spike body 1, causing the four protruding ribs 2 of the spike body 1 to press down due to the force. As a result, the lower block 42 will move down synchronously. The lower block 42 gradually slides down from the receiving ring groove 53 to the buffer arc surface 54. The buffer arc surface 54 can buffer and release the pressure, reduce the pressure impact, and prevent the armored spike from being damaged after being rolled over by the tires. The fixing post 5 automatically springs back to its original state, and the spike body 1 returns to its initial height to ensure its normal use.

[0028] When replacing the main body 1 of the road spike, simply press the upper half of the four fixing posts 5 together again, and the fixing block 4 can be pulled out upwards until the entire main body 1 of the road spike is removed, making the operation more convenient.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
