Description

Technical Field

[0001] This utility model relates to a multifunctional guardrail for municipal roads. Background Technology

[0002] Existing municipal road guardrails are generally fixed and difficult to disassemble, with a single function: traffic isolation. To expand the functionality of municipal road guardrails beyond traffic isolation, applications in road construction, landscaping, and traffic guidance have led to the design of various easily detachable guardrails. This ease of assembly and disassembly allows the same set of guardrails to be used in different scenarios. For example, Chinese Utility Model Patent CN 222614975 U discloses a combined temporary construction site guardrail, which consists of multiple cones (also known as road cones or traffic cones) and multiple connecting rods. The cones are arranged at intervals along a predetermined direction, with a connecting rod between adjacent cones, thus forming the guardrail. The connecting rod typically consists of a rod body and collars at both ends of the rod body. The collars are fixedly fitted onto the ends of the rod body and can be worn over the cones. This type of guardrail has a simple structure, and its installation and dismantling are convenient and quick, making it suitable not only for construction sites but also for road traffic isolation, landscaping, and traffic guidance, offering a variety of functions. However, when storing the connecting rods, the collar occupies a large amount of space in the diameter direction of the connecting rod, making it inconvenient to stack the connecting rods vertically and easily damaging the collar. Utility Model Content

[0003] The purpose of this utility model is to provide a multifunctional guardrail for municipal roads, comprising multiple spaced traffic cones, with connecting rods installed between adjacent traffic cones. Each connecting rod includes a rod body and collars at both ends of the rod body. Each collar includes a ring body for fitting around the traffic cone and a sleeve body for fitting around the end of the rod body. The sleeve body includes an outer sleeve and an inner insert post within the outer sleeve. The rod body is hollow, with through holes at both ends for inserting the inner insert post of the sleeve body. An annular socket cavity for inserting the rod body is formed between the outer sleeve and the inner insert post. The end of the rod body is inserted into the annular socket cavity of the sleeve body in a pluggable manner, wherein the outer sleeve of the sleeve body fits over the rod body after being inserted into the annular socket cavity at the end of the rod body; the inner insert post of the sleeve body is inserted into the through hole at the end of the rod body after being inserted into the annular socket cavity at the end of the rod body; the inner insert post of the sleeve body is provided with a blocking mechanism to prevent the rod body from being pulled out of the annular socket cavity.

[0004] The pole and collar of this invention are assembled in a pluggable manner, allowing for easy assembly and disassembly of the collar. When installing the guardrail, the pole and collar are assembled together; when storing, they are separated, saving storage space and reducing the risk of collar damage. In this embodiment, an obstruction mechanism is incorporated to reduce the risk of the guardrail collapsing due to accidental detachment of the pole and collar after installation. When assembling or disassembling the pole and collar, only the force applied to overcome the obstruction mechanism is needed to separate them. Attached Figure Description

Detailed Implementation

[0019] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution.

[0020] like Figures 1 to 12 The multi-functional guardrail for municipal roads shown includes multiple spaced-apart traffic cones 10. A connecting rod 20 is installed between two adjacent traffic cones 10. Each connecting rod 20 includes a rod body 30 and collars 40 at both ends of the rod body 30. Each collar 40 includes a ring body 50 for fitting around the traffic cone 10 and a sleeve body 60 for fitting around the end of the rod body 30.

[0021] The sleeve 60 includes an outer sleeve 601 and an inner insert post 602 disposed in the outer sleeve 601. In this embodiment, the ring 50 is fixed on the outer sleeve 601.

[0022] The rod body 30 is hollow, and both ends of it have through holes 301 for inserting the inner insert post 602 of the sleeve body;

[0023] The outer sleeve 601 of the sleeve and the inner insert post 602 form an annular socket 603 for inserting the rod body 30;

[0024] The end of the rod 30 is inserted into the annular socket 603 of the sleeve in a pluggable manner, wherein,

[0025] The outer sleeve 601 of the sleeve is inserted into the annular socket 603 at the end of the rod 30 and then sleeved over the rod 30;

[0026] The inner insert post 602 of the sleeve is inserted into the annular socket 603 at the end of the rod 30 and then into the end through hole 301 of the rod;

[0027] The inner insert post 602 of the sleeve is provided with a blocking mechanism to prevent the rod 30 from being pulled out of the annular socket 603.

[0028] The disclosed technical solution allows for the assembly of the pole and the collar in a pluggable manner, enabling the collar to be disassembled and assembled. When it is necessary to erect a guardrail, the pole and the collar are assembled together, and when it is necessary to store, the pole and the collar are separated and stored separately. This not only saves storage space but also reduces the risk of collar damage.

[0029] In this embodiment, by setting an obstruction mechanism, the risk of the guardrail falling apart due to accidental detachment of the pole and collar after the guardrail is erected is reduced. When disassembling and assembling the pole and collar, only the force of overcoming the obstruction mechanism needs to be applied to separate the pole and collar.

[0030] The obstruction mechanism includes a positioning bead 70 disposed on the side wall of the inner insertion post 602. In this embodiment, the positioning bead (also known as a spring bead or spring plunger) can be made using existing technology and consists of a housing, a spring and a ball.

[0031] The ends of the rod 30 are respectively provided with positioning holes 302 for the positioning ball 701 to be inserted;

[0032] The positioning ball 701, after being inserted into the annular socket 603 at the end of the rod, sinks into the positioning hole 302 at the end of the rod, thus preventing the rod 30 from being pulled out of the annular socket 603. When it is necessary to pull out the rod, after applying opposite pulling forces to the rod and the collar, the rod will press down on the ball, and finally the rod will slide past the ball and be pulled out of the annular socket. The obstruction mechanism disclosed in this technical solution has a simple structure and facilitates the assembly and disassembly of the rod and the collar.

[0033] In this embodiment, in addition to using the aforementioned positioning bead, the obstruction mechanism can also employ a rubber ring (not shown in the figure) fitted outside the inner insertion post, which can increase the friction between the rod and the collar.

[0034] The positioning hole 302 at the end of the rod is an elongated strip extending circumferentially around the rod. This design facilitates the entry of the positioning ball into the positioning hole, and also facilitates the installation of the rod and the collar. During the assembly of the rod and the collar, after the end of the rod is inserted into the annular socket, rotating the collar will cause the positioning ball to sink into the positioning hole.

[0035] The outer sleeve 601 is provided with a central blind hole 604, and a central positioning protrusion 605 is provided at the bottom of the central blind hole 604;

[0036] The inner insert 602 is provided with a central positioning hole for the central positioning protrusion 605 to be inserted;

[0037] The central positioning protrusion 605 is inserted into the central positioning hole 606 when the inner insertion post 602 is inserted into the central blind hole 604, so as to position the inner insertion post 602.

[0038] A screw 80 passes through the inner insert post 602 and is screwed into the central positioning protrusion 605 to lock the inner insert post 602 in the outer sleeve 601. This technical solution uses screws to assemble and disassemble the outer sleeve and the inner insert post, which facilitates the processing and assembly of the collar.
