Description

Technical Field

[0001] This utility model relates to the field of road safety technology, specifically a reflective delineator for highways. Background Technology

[0002] Road delineators are important safety facilities installed on road edges or medians. Their reflective properties provide road alignment guidance for nighttime driving, playing a crucial role in ensuring traffic safety. With the continuous increase in highway mileage and the improvement of traffic safety standards, higher demands are placed on the reliability, durability, and ease of maintenance of road delineators. Especially on special road sections such as curves and ramps, road delineators are easily damaged by vehicle collisions. Improving their impact resistance and reducing maintenance costs has become a problem that needs to be solved.

[0003] Existing highway delineators typically consist of reflectors, posts, and bases. The reflectors are usually fixed to the posts by adhesive or riveting, while the posts are mostly integral structures that are directly inserted into or fixed to the bases via flanges. The bases are usually made of concrete or are piles driven directly into the ground.

[0004] This type of structure has the following drawbacks during use: the entire delineator needs to be replaced after the reflector is damaged, resulting in high maintenance costs; the posts are mostly rigid structures, which are prone to permanent deformation or breakage after being hit by vehicles; the base has a single fixing method, making it difficult to disassemble and maintain the connection with the post, and the stability of the connection with the ground is insufficient. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a reflective delineator for highways, which solves the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a highway reflective delineator, comprising a delineator assembly, a buffer assembly, and an anchoring assembly. The bottom of the delineator assembly is connected to the buffer assembly, and the bottom of the buffer assembly is fixedly installed with the anchoring assembly. The delineator assembly includes an upper column, the interior of which is provided with six sets of snap-fit ​​plates. Reflective plates are fixedly connected to the outer sides of each of the six sets of snap-fit ​​plates via connecting plates. The bottom of each of the six sets of snap-fit ​​plates is connected to a snap-fit ​​block via two sets of No. 1 springs. The buffer assembly includes a lower column, the top of which is fixedly connected to a ball head via a support column. Three sets of No. 2 springs are fixedly connected to the top of the lower column. Bolts are inserted on both sides of the lower column, and a protective sleeve is fitted over the lower column. The anchoring assembly includes a connecting column, the bottom of which is fixedly connected to a chassis. A No. 1 ground stake is fixedly connected to the bottom of the chassis, and four sets of No. 2 ground stakes are fixedly connected to the bottom of the chassis.

[0009] Optionally, the upper column has six sets of spaces on its inner and outer sides that mate with the snap-fit ​​plate, connecting plate, and snap-fit ​​block. The opening height of the spaces on the upper column matches the height of the snap-fit ​​plate and snap-fit ​​block. A chamfer is provided at the lower part of the entrance to the spaces on the upper column. A slot is provided at the bottom of the inner side of the upper column that mates with the support column and ball head. A chamfer is provided at the entrance to the slot on the upper column. The matching of dimensions and the chamfer design in this structure ensure the rapid alignment and installation of each component, effectively improving the stability of the assembly.

[0010] Optionally, the bottom end of the snap-fit ​​plate and the top end of the snap-fit ​​block are provided with two sets of grooves that cooperate with the No. 1 spring. The size of the reflector is larger than that of the snap-fit ​​plate and the connecting plate. This structure ensures the stabilizing effect of the No. 1 spring. The increased area of ​​the reflector covers the opening, further improving the protection performance of the interior.

[0011] Optionally, the lower column is provided with threaded slots that mate with two sets of bolts, and the lower column is provided with slots that mate with connecting columns. The three sets of second springs are located at the three corners of the top of the lower column. The spring layout in this structure provides a balanced buffering and restoring capability, ensuring that the column can stably return to a vertical state after being impacted.

[0012] Optionally, the protective sleeve has a corrugated tubular structure and is shaped to fit the outer surfaces of the upper and lower columns. The delineator assembly and the buffer assembly are snap-fit ​​connected, and the protective sleeve is fitted at the connection between the delineator assembly and the buffer assembly. The structure of the protective sleeve provides excellent sealing protection while ensuring flexibility, effectively preventing mud and debris from entering the internal components.

[0013] Optionally, the connecting column has a threaded groove inside that mates with two sets of bolts. The position of the threaded groove on the connecting column matches the position of the threaded slot on the lower column. A No. 1 ground pile is fixedly connected to the middle of the bottom of the chassis, and four sets of No. 2 ground piles are fixedly connected to the bottom of the chassis near the edge. The No. 1 ground pile is larger than the No. 2 ground pile. This connection design ensures stability and firmness, significantly enhances the reliability of the connection, and the different ground pile sizes form a primary and secondary anchoring system, which not only ensures the main pull-out resistance but also provides stable support to the surrounding area.

[0014] (III) Beneficial Effects

[0015] This utility model provides a reflective delineator for highways, which has the following advantages:

[0016] 1. This highway reflective delineator employs a modular design, allowing the reflector to form an independent unit via a snap-fit ​​plate, connecting plate, spring, and snap-fit ​​block, which is then snapped and fixed to the upper column. This enables rapid replacement of key components. Maintenance does not require replacing the entire delineator; only the damaged reflector unit needs partial replacement. This simplified operation significantly improves maintenance efficiency and reduces maintenance costs.

[0017] 2. This reflective road delineator utilizes a buffer structure consisting of a support post, a ball joint, and a No. 2 spring. This structure provides cushioning and recovery capabilities when the delineator assembly is impacted. The support post and ball joint allow the delineator assembly to tilt slightly upon impact, while the No. 2 spring reduces the impact force, effectively preventing permanent bending or breakage of the rigid structure and significantly reducing maintenance frequency and costs. The addition of a protective sleeve provides protection at the connection between the delineator assembly and the buffer assembly, extending the device's lifespan and further reducing maintenance frequency.

[0018] 3. This reflective highway delineator features independent anchoring components that connect to the buffer components via plug-in joints and are secured with bolts. This design ensures strong connections while facilitating easy disassembly and installation, as well as convenient transportation, storage, and maintenance. The base, coupled with a No. 1 ground stake and four sets of No. 2 ground stakes at the bottom, achieves a robust and adaptable installation. The multi-stake distribution provides excellent anti-tipping capabilities, ensuring stability even in soft soil. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a highway reflective delineator, including a delineator component 1, a buffer component 2, and an anchoring component 3. The bottom of the delineator component 1 is connected to the buffer component 2, and the bottom of the buffer component 2 is fixedly installed with the anchoring component 3. The delineator component 1 includes an upper column 11, and the interior of the upper column 11 is provided with six sets of snap-fit ​​plates 12. The outer sides of each of the six sets of snap-fit ​​plates 12 are fixedly connected to a reflector 14 through a connecting plate 13. The bottom of each of the six sets of snap-fit ​​plates 12 is connected to a reflector 14 through two sets of No. 1 springs 15. The snap-fit ​​block 16; the buffer assembly 2 includes a lower column 21, the top of the lower column 21 is fixedly connected to a ball head 23 via a support column 22, the top of the lower column 21 is fixedly connected to three sets of No. 2 springs 24, bolts 25 are inserted on both the left and right sides of the lower column 21, and a protective sleeve 26 is fitted on the outside of the lower column 21; the anchoring assembly 3 includes a connecting column 31, the bottom end of the connecting column 31 is fixedly connected to a chassis 32, the bottom of the chassis 32 is fixedly connected to a No. 1 ground stake 33, and the bottom of the chassis 32 is fixedly connected to four sets of No. 2 ground stakes 34.

[0027] The upper column 11 has six sets of spaces on its inner and outer sides that mate with the snap-fit ​​plate 12, connecting plate 13, and snap-fit ​​block 16. The opening height of the spaces in the upper column 11 matches the height of the snap-fit ​​plate 12 and snap-fit ​​block 16. The lower part of the entrance to the spaces in the upper column 11 is chamfered. The bottom of the interior of the upper column 11 has a slot that mates with the support column 22 and ball head 23. The entrance to the slot in the upper column 11 is chamfered. The bottom of the snap-fit ​​plate 12 and the top of the snap-fit ​​block 16 each have two sets of grooves that mate with the first spring 15. The reflector 14 is larger than the snap-fit ​​plate 12 and the connecting plate 13. The lower column 21 has a threaded slot that mates with two sets of bolts 25. The lower column 21 has a slot that mates with the connecting column 31. Three sets of No. 2 springs 24 are located at the three corners of the top of the lower column 21. The protective sleeve 26 is a corrugated tubular structure. The protective sleeve 26 is shaped to fit the outer surfaces of the upper column 11 and the lower column 21. The delineator assembly 1 and the buffer assembly 2 are snap-fit ​​connected. The protective sleeve 26 is fitted at the connection between the delineator assembly 1 and the buffer assembly 2.

[0028] In this utility model, the working steps of the device are as follows: When the reflector 14 is damaged, it is not necessary to replace the entire delineator assembly 1; only the damaged reflector 14 needs to be replaced separately. The reflector 14 is slid downwards, causing the inner connecting plate 13 and the locking plate 12 to move downwards together. The locking plate 12 moves downwards, compressing the first spring 15. The top of the locking plate 12 disengages from the groove at the top of the inner end of the upper column 11. Then, the reflector 14 is tilted to disengage it from the upper column 11. A new reflector 14 is then installed. The reflector plate 14 is tilted so that the inner snap-fit ​​plate 12, the bottom spring 15, and the snap-fit ​​block 16 can smoothly enter the groove inside the upper column 11. Then, the snap-fit ​​plate 12 is pressed down, which compresses the spring 15 downward, leaving space for the upper part of the snap-fit ​​plate 12 to enter the groove. Then, the snap-fit ​​plate 12 is released, and the spring 15 exerts an upward force on the snap-fit ​​plate 12, so that the top of the snap-fit ​​plate 12 enters the slot inside the upper column 11, completing the disassembly and installation of the reflector plate 14. This quick-release structure significantly improves the maintenance efficiency of the device. Insert the support column 22 and ball head 23 into the slot at the bottom of the delineator assembly 1 to complete the connection between the delineator assembly 1 and the buffer assembly 2. The structure of the support column 22 and ball head 23, in conjunction with the groove at the bottom of the delineator assembly 1, allows the delineator assembly 1 to tilt at a certain angle when it is impacted. At the same time, three sets of No. 2 springs 24 work together to absorb part of the impact energy. After the impact, the column can automatically return to its original position under the action of the spring restoring force. A compressible protective sleeve 26 is provided at the connection between the delineator assembly 1 and the buffer assembly 2, which provides a certain degree of protection to the connection components without affecting the buffering effect, significantly improving the durability and stability of the device.

[0029] Please see Figure 4 andFigure 5 Based on the same concept as the above embodiments, this embodiment also proposes that: the connecting column 31 has a threaded groove inside that mates with two sets of bolts 25, the position of the threaded groove on the connecting column 31 matches the position of the threaded slot on the lower column 21, a first ground pile 33 is fixedly connected to the middle position of the bottom of the chassis 32, and four sets of second ground piles 34 are fixedly connected to the bottom of the chassis 32 near the edge, the first ground pile 33 is larger than the second ground pile 34.

[0030] In the above embodiment, the anchoring component 3 is inserted into the ground, and the No. 1 ground pile 33 at the bottom of the chassis 32 provides the main pull-out resistance of the device. The four sets of No. 2 ground piles 34 around it provide the anti-tipping effect, which improves the overall stability. Then, the buffer component 2 is sleeved on the outside of the connecting column 31 and fixed by two sets of bolts 25 to complete the connection between the buffer component 2 and the anchoring component 3. The device achieves easy disassembly and assembly while ensuring stability, which significantly improves maintenance efficiency.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
