Technical Field

[0001] The utility model relates to a convenient wave guardrail transition connection device, belonging to the field of wave guardrails. Background Art

[0002] The wave guardrail transition plate is an important safety facility in highway traffic facilities. The construction of the guardrail plate involves the transition connection between double-layer double-wave and triple-wave plates. After the positions of the double-layer double-wave and triple-wave plates are fixed, the pitch of the rivet holes on the double-layer double-wave and triple-wave plates is limited. When using the wave guardrail transition plate to connect the double-layer double-wave and triple-wave plates, due to the fixed size of the wave guardrail transition plate, there is a situation where the rivet holes on the wave guardrail transition plate are not aligned with the rivet holes on the double-layer double-wave and triple-wave plates during the construction process, thus increasing the installation difficulty of the wave guardrail transition plate. Therefore, it is necessary to design a convenient wave guardrail transition connection device. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a convenient wave guardrail transition connection device to solve the problems raised in the above background art. The utility model realizes adjusting the distance between the rivet holes and the wave guardrail transition plate as needed, and reduces the installation difficulty.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions: A convenient wave guardrail transition connection device includes a wave guardrail transition plate. One end of the wave guardrail transition plate is a triple-wave transition part, and the other end of the wave guardrail transition plate is a quadruple-wave transition part. A triple-wave transition plate is arranged on one side of the wave guardrail transition plate close to the triple-wave transition part, and a quadruple-wave transition plate is arranged on one side of the wave guardrail transition plate close to the quadruple-wave transition part. Two screw rods are installed on the surfaces of both the triple-wave transition part and the quadruple-wave transition part, and two supporting ears matched with the screw rods are installed on the surfaces of both the triple-wave transition plate and the quadruple-wave transition plate. A perforation is formed on one side surface of the supporting ear, the screw rod penetrates through the perforation, and first nuts are arranged on both sides of the perforation along the length direction of the screw rod, and the first nuts are threadedly connected to the screw rod.

[0005] Furthermore, two connecting ears matched with the screw rods are fixedly connected to the surfaces of both the triple-wave transition part and the quadruple-wave transition part, and one end of the screw rod is connected to the connecting ear.

[0007] Further, a threaded blind hole is provided in the middle position at one end of the screw, and a threaded head matching the threaded blind hole is fixedly connected to the end of the screw away from the threaded blind hole. The threaded head on one screw is threadedly connected into the threaded blind hole on another screw.

[0008] Further, the three-wave transition part and the corrugated guardrail transition plate are of an integrally formed structure, and the four-wave transition part and the corrugated guardrail transition plate are of an integrally formed structure.

[0012] 2.

Two screws 8 are installed on the surfaces of both the three-wave transition part 5 and the four-wave transition part 4. Among them, two connecting ears 12 that cooperate with the screw 8 are fixedly connected to the surfaces of both the three-wave transition part 5 and the four-wave transition part 4.
