[0026] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar units or units having the same or similar functions throughout.

[0027] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that terms such as "installation", "connection", and "fixing" should be interpreted broadly, and can refer to direct connection, installation or fixing, or indirect connection, installation or fixing, and the present invention does not impose any limitation in this regard.

[0028] like Figures 1 to 4 The diagram illustrates an embodiment of a road pier protection device of this utility model. It includes a first buffer section 5 connected to the pier body; a first protective section comprising multiple detachably connected first splicing units 1, with the first buffer section 5 internally connected to the corresponding first splicing unit 1; a second protective section comprising multiple second splicing units 4 detachably connected to each other and fitted over the first protective section; and a second buffer section connecting the first splicing units 1 and the second splicing units 4. In this embodiment, both the first splicing units 1 and the second splicing units 4 are arc-shaped to form a circumferential cylindrical structure, suitable for external protection of most pier bodies. Preferably, there are two first splicing units 1, each prepared as a semi-circular internal splicing protective cylinder; and two second splicing units 4, each prepared as a semi-circular external splicing protective cylinder. In this embodiment, multiple buffers can be formed by the first buffer part 5 and the second buffer part to better reduce the damage caused by minor collisions between the pier body and pedestrians or vehicles; the buffer structure can also provide certain support between the first splicing unit 1 and the pier body, and between the first splicing unit 1 and the second splicing unit 4, thereby improving the service life of the road pier protection device.

[0029] In this embodiment, an outer protective part is also included, comprising a flexible protective layer 3, which is externally connected to the second splicing unit 4. Preferably, the flexible protective layer 3 is a protective cotton layer covering the second splicing unit 4. In this embodiment, the flexible protective layer 3 can be used not only for the protection of road piers but also for the protection of pedestrians. When a pedestrian accidentally bumps into a pier, the softness of the flexible protective layer 3 can reduce the injury to pedestrians or vehicles from minor collisions, reduce the hard contact between pedestrians, vehicles, and the road pier protection device, and better reduce the pain felt by pedestrians after a collision.

[0030] In this embodiment, the outer protective part also includes a reflective warning element 9, which is connected to the flexible protective layer 3. Preferably, the reflective warning element 9 is a reflective strip, which can be pasted on the outside of the protective cotton layer to serve as a warning, improve the warning effect, and reduce the chance of the pier being bumped or knocked.

[0031] In this embodiment, the first buffer part 5 is a rubber sleeve, which can be connected to the inner wall of the corresponding first splicing unit 1 by adhesive bonding. It has a simple structure, good buffering effect, is easy to install, and also ensures stability after installation.

[0032] In this embodiment, the second buffer section includes multiple spring assemblies 6. After the road pier protection device is assembled, both ends of each spring assembly 6 are connected to the corresponding first splicing unit 1 and second splicing unit 4, respectively. The multiple spring assemblies 6 are evenly distributed at equal intervals along the circumference of the pier body. The axis of each spring is perpendicular to the center line of the pier body. That is, the axis of the spring is as perpendicular as possible to the cylindrical axis of the cylindrical structure formed by the first or second protective section. The mutual cooperation can better achieve the buffering effect.

[0033] In this embodiment, at least one limiting plate 2 is also included. The limiting plate 2 is connected to the second splicing unit 4, and the limiting plate 2 can contact the top or bottom of the first splicing unit 1 to limit its position. This embodiment can improve installation accuracy and efficiency, and ensure the protective effect. The limiting plate 2 can be placed at the bottom of the second splicing unit 4 to support the first protective part; the limiting plate 2 can also be placed at the top of the second splicing unit 4 to limit the first protective part, so that the first and second protective parts can better form a whole, avoid misalignment, and ensure the stability of the structure and the protective effect.

[0034] In this embodiment, the first protective part further includes a first connecting component for connecting adjacent first splicing units 1. The first connecting component includes a first connecting plate 7 connected to the corresponding first splicing unit 1 and a first bolt assembly 8 for connecting the corresponding first connecting plate 7. The second protective part further includes a second connecting component for connecting adjacent second splicing units 4. The second connecting component includes a second connecting plate 12 connected to the corresponding second splicing unit 4 and a second bolt assembly 13 for connecting the corresponding second connecting plate 12. The first and second connecting components enable quick connection of the splicing units, providing convenient operation and a stable connection effect.

[0035] In this embodiment, at least some of the connecting ends of the first splicing unit 1 and the second splicing unit 4 are provided with plug-in structures. The plug-in structures include plug-in slots 10 formed at corresponding ends and plug-in components 11 adapted to the plug-in slots 10. Preferably, one splicing end of each first splicing unit 1 has a plug-in slot 10 and the other splicing end is provided with a plug-in component 11; one splicing end of the second splicing unit 4 has a plug-in slot 10 and the other splicing end is provided with a plug-in component 11. The plug-in structures provided in the first splicing unit 1 and the plug-in structures provided in the second splicing unit 4 have identical structures, and their sizes can be adjusted based on suitability for use. By cooperating with the first connecting component and the second connecting component through the plug-in structures, the stability of the structural connection is improved, ensuring the service life of the road pier protection device.

[0036] In this embodiment, the insertion slot 10 includes a transition slot 101 and a locking slot 102. The locking slot 102 communicates with the transition slot 101. The transition slot 101 is used to introduce the insertion piece 11, and the locking slot 102 is used to secure the insertion piece 11. The insertion piece 11 includes a locking section 112 adapted to the shape of the locking slot 102 and a connecting section 111 connected to the locking section 112. Preferably, the connecting section 111 is used to connect to the splicing end of the corresponding first splicing unit 1 or second splicing unit 4; the locking section 112 tapers vertically away from the connecting section 111, and has an inverted triangular or inverted trapezoidal cross-section. The locking section 112 can match the taper angle of the internal cavity of the locking slot 102; the lateral width of the transition slot 101 is not less than the maximum width of the locking slot 102 to allow the lateral introduction of the insertion piece 11. The insertion structure can better prevent the first protective part and the second protective part from detaching after splicing.

[0037] On the other hand, the method of using this utility model includes the following steps:

[0038] Prefabricate a first buffer section 5 according to the shape and size of the road pier body. Install a rubber sleeve on the outside of the pier body and bond it to the corresponding first splicing unit 1. Fix one set of first splicing units 1 and second splicing units 4, and then install other adjacent sets of first splicing units 1 and second splicing units 4 in sequence. When splicing adjacent first splicing units 1 or second splicing units 4, the plug-in structure can be used. The plug-in part 11 can be inserted laterally into the transition groove 101, and then the locking section 112 can be pressed down to lock into the locking groove 102 to achieve splicing. Finally, the corresponding first connecting plate 7 is aligned and the first bolt assembly 8 is installed; the corresponding second connecting plate 12 is aligned and the second bolt assembly 13 is installed to achieve multiple connections to ensure the stability of the installation. Finally, the first buffer section 5 is installed on the outside of the pier body; the first splicing unit 1 is spliced ​​on the outside of the first buffer section 5; and the second splicing unit 4 is spliced ​​on the outside of the first splicing unit 1, forming multiple layers of protection on the outside of the pier body.

[0039] In this embodiment, the stability of the structure after installation is ensured by using a limiting plate 2 for axial limiting, a plug-in structure for lateral locking, and a bolt connection for longitudinal locking. Two sets of protective cylinders, inner and outer, can be formed by the cooperation of the first and second protective parts. A buffer structure is provided between the first protective part and the pier body, and between the first and second protective parts. That is, when the road pier protection device is subjected to external impact, the outer and second protective parts are subjected to force first, which in turn causes the spring assembly 6 to deform under impact, buffering the impact force. If the impact force continues, the first protective part will compress the first buffer part 5, which deforms to buffer the impact, forming a multi-layered buffer protection structure. The flexible nature of the outer protective part further reduces the injury to pedestrians caused by the impact, reducing pain.
