Description

Technical Field

[0001] This utility model relates to the technical field of road and bridge construction ancillary facilities, specifically to a detachable fastener for quickly fixing traffic signs. Background Technology

[0002] Road traffic signs are graphic symbols that display traffic regulations and road information. They provide a vivid, concrete, and concise representation of traffic regulations, and are used to manage traffic, indicate driving directions, and ensure smooth traffic flow and driving safety.

[0003] In short-term maintenance work on highways, cross-sea bridges, and other roads, it is often necessary to temporarily install traffic signs on existing crash barriers. Circular tube crash barriers are those where horizontal circular tubes (beams) bear the main impact protection. Currently, the common method for fixing traffic signs to circular tube crash barriers is by binding with wire or wrapping with rope. This method has many drawbacks: First, the installation and dismantling process is cumbersome and inefficient, consuming a lot of manpower and time, and increasing the risk of maintenance workers being exposed to traffic; second, wire and rope are disposable consumables, which not only waste resources but also have poor stability and wind resistance, easily loosening and falling off, posing safety hazards; third, wire binding may scratch the anti-corrosion layer of the barrier, accelerating corrosion. Therefore, there is an urgent need for a dedicated fixing device that is reusable, easy to install and dismantle, reliably connected, and effectively protects the barrier to solve the above technical problems. Utility Model Content

[0004] In view of the above problems, this utility model is proposed to provide a detachable fastener for quickly fixing traffic signs to overcome or at least partially solve the above problems.

[0005] The detachable fastener for the quick-fixing traffic sign includes a U-shaped fastener body, a first locking rod, and a second locking rod. The fastener body is used to fasten onto the horizontal circular tube of the circular tube crash barrier, and it consists of a semi-circular overlapping portion, and a first extension portion and a second extension portion respectively connected to both ends of the overlapping portion. A first shaft is fixed to the outer side of the first extension portion, and a first sleeve fitted onto the first shaft is fixed to one end of the first locking rod. An extension plate is fixed to the second extension portion, and the first locking rod can rotate to a position where it engages with the first slot of the extension plate. The second extension is plate-shaped, and a first side plate and a second side plate, both perpendicular to the outer side of the second extension facing away from the first extension, are fixed to the outer side of the second extension. The first side plate, the second side plate, and the second extension together form a limiting groove facing away from the first extension. The limiting groove is used to constrain the post of the road traffic sign placed therein. A second shaft is fixed to the outer side of the first side plate, and a second sleeve sleeved to the second shaft is fixed to one end of the second locking rod. The second locking rod can rotate to the position where it is engaged with the second slot of the second side plate.

[0006] In one embodiment, the inner wall of the buckle is fixed with an anti-slip elastic pad.

[0007] In one embodiment, the first shaft is fixed with two stops that are respectively adjacent to both ends of the first sleeve.

[0008] In one embodiment, the extension plate is fixedly connected to the edge of the second extension away from the overlap.

[0022] The following description, with reference to the accompanying drawings, describes a detachable fastener for quickly fixing traffic signs according to an embodiment of the present invention.

[0023] See Figure 1 and Figure 2According to an embodiment of the present invention, a detachable fastener for quickly fixing traffic signs includes a U-shaped fastener body 1, a first locking rod 2, and a second locking rod 3. The fastener body 1 consists of a semi-circular overlapping portion 4, and a first extension portion 5 and a second extension portion 6 respectively connected to both ends of the overlapping portion 4. Specifically, the fastener body 1 can be formed by bending flat steel or by casting metal. A first shaft 7 is fixed to the outer side of the first extension portion 5. Specifically, the first shaft 7 can be fixed to the outer side of the first extension portion 5 by welding. The first locking rod 2 can be a long strip-shaped rod, with a first sleeve 8 fixed at one end to the first shaft 7. The first locking rod 2 and the first sleeve 8 form a T-shaped structure, and the first locking rod 2 can rotate about the first shaft 7 as a central axis. To prevent the first locking rod 2 from displacing axially relative to the first shaft 7 during rotation, or from displacing too much axially relative to the first shaft 7, the first shaft 7 is fixed with two stops 9 adjacent to both ends of the first sleeve 8. Specifically, both stops 9 can be fixed to the first shaft 7 by welding.

[0024] The second extension 6 is fixed with an extension plate 10. In this embodiment, the extension plate 10 is welded to the edge of the second extension 6 away from the overlapping part 4. The first locking rod 2 can be rotated to the position where it engages with the first slot 11 of the extension plate 10 (i.e., the locked position) to close the opening of the buckle body 1. To prevent the first locking rod 2 from accidentally leaving the position where it engages with the first slot 11 of the extension plate 10, a protrusion can be formed on the groove wall of the first slot 11 near the groove opening. During the installation of the traffic sign, the first locking rod 2 is first rotated to the open position, such as... Figure 3 As shown in the diagram, fasten body 1 is then fastened onto the horizontal circular tube of the circular tube crash barrier. Adjust fasten body 1 so that its opening faces downwards, and then rotate the first locking rod 2 to the locked position. At this point, the fasten body 1 is installed.

[0025] In this embodiment, an anti-slip elastic pad (not shown in the figure) is fixed to the inner wall of the buckle body 1. The anti-slip elastic pad can be a strip of rubber sheet, which is adhered to the inner wall of the buckle body 1 to increase the friction between the buckle body 1 and the transverse circular tube of the circular tube anti-collision guardrail, avoid scratching the anti-corrosion layer of the guardrail, and reduce the energy transmitted to the fastener by road vibration, thereby reducing the vibration amplitude borne by the fastener.

[0026] The second extension 6 is plate-shaped. A first side plate 12 and a second side plate 13, both perpendicular to the outer surface of the second extension 6 facing away from the first extension 5, are fixed to the outer surface of the second extension 6. Specifically, if the first side plate 12, the second side plate 13, and the second extension 6 are all made of metal, the first side plate 12 and the second side plate 13 can be fixed to the outer surface of the second extension 6 by welding. The first side plate 12, the second side plate 13, and the second extension 6 together form a limiting groove 14 with its opening facing away from the first extension 5. The limiting groove 14 is used to constrain the post of the road traffic sign placed within it. Figure 2 From a certain perspective, the limiting groove 14 extends along the height direction and can constrain the movement of the road traffic sign post placed therein in the left, right and rear directions, that is, to prevent the road traffic sign from moving in the left, right and rear directions.

[0027] A second shaft 15 is fixed to the outer side of the first side plate 12. The second locking rod 3 can be a long strip-shaped rod, with a second sleeve 16 fixed to one end of the second shaft 15. The second locking rod 3 and the second sleeve 16 form a T-shaped structure, and the second locking rod 3 can rotate about the second shaft 15 as the central axis. To prevent the second locking rod 3 from displacing axially relative to the second shaft 15 during rotation, or from displacing too much axially relative to the second shaft 15, the second shaft 15 is fixed with two stops 9 adjacent to both ends of the second sleeve 16. Specifically, both stops 9 can be fixed to the second shaft 15 by welding.

[0028] The second locking rod 3 can be rotated to the position where it engages with the second slot 17 of the second side plate 13 (i.e., the locked position) to close the opening of the second slot 17. To prevent the second locking rod 3 from accidentally leaving the position where it engages with the second slot 17 of the second side plate 13, a protrusion is formed on the groove wall of the second slot 17 near the opening. During the installation of the traffic sign, after the buckle 1 is installed (the opening of the second slot 17 must face the road side), the second locking rod 3 is rotated to the open position (this step can also be performed before the buckle 1 is fastened to the horizontal tube of the circular tube crash barrier), the post of the road traffic sign is pushed into the second slot 17, and finally the second locking rod 3 is rotated to the locked position. In practical applications, a single detachable fastener for quickly fixing a traffic sign can be used to fix a traffic sign to the circular tube crash barrier, or two or more detachable fasteners for quickly fixing traffic signs can be used together to fix a traffic sign to the circular tube crash barrier.

[0029] The detachable fastener for quickly fixing traffic signs in this embodiment adopts a guillotine-type opening and closing design (i.e., the first locking rod closes the opening of the fastener body, and the second locking rod closes the slot of the limiting groove), which can realize the rapid installation and removal of traffic signs, improve work efficiency, reduce the work risks of maintenance workers, and can be reused with high reliability.
