Description

Technical Field

[0001] This utility model relates to the field of highway guardrail technology, and in particular to a highway guardrail that can be quickly assembled. Background Technology

[0002] Rapidly assembled highway guardrails typically consist of multiple standardized components, including bases, brackets, connectors, and guardrail posts. The base is fixed to the ground using bottom expansion bolts. The brackets are inserted into the slots in the base. The connectors are the key components for rapid guardrail assembly. Each end of the guardrail post is inserted into a connector installed on one of the two brackets. At this point, a section of the guardrail is installed, thus achieving rapid assembly of the highway guardrail.

[0003] Highway guardrails are generally assembled from multiple guardrails. When a guardrail is damaged and needs to be replaced, the damaged guardrail can be disassembled by tools. The new guardrail needs to be placed between two brackets. The connector is located outside the guardrail and protrudes from the bracket. Since both ends of the guardrail need to be connected to the connector, and the connector needs to be fitted onto the outside of the guardrail, the connector needs to be disassembled in order for the guardrail to fit between the two brackets. Each connector is installed on the outside of the bracket with two screws, and one guardrail needs to be connected to four connectors. This makes the replacement process cumbersome and reduces the efficiency of guardrail replacement. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a highway guardrail that can be quickly assembled. It solves the technical problem that when a guardrail is inserted between two supports, the connecting parts need to be disassembled, and one guardrail needs to be connected to four connecting parts, which leads to a cumbersome replacement process and reduces the replacement efficiency of the guardrail.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A highway guardrail that can be quickly assembled includes a bracket with two connectors at both ends. Each connector has a connecting block fixedly installed on its exterior. The bracket has a connecting mechanism on its exterior, which includes a limiting screw, a fixing plate, and a nut. The limiting screw is fixedly installed on the exterior of the bracket, the fixing plate is slidably connected to the exterior of the limiting screw, and the nut is threadedly connected to the exterior of the limiting screw. The bracket has two sliding grooves on its exterior, the connecting blocks are slidably connected to the interior of the sliding grooves, and both ends of the fixing plate are slidably connected to the interiors of the two sliding grooves, with the connecting blocks fitting against the exterior of the fixing plate.

[0009] The fixed plate has through holes on its exterior. The fixed plate is slidably connected to the outside of the limiting screw through the through holes. Each groove has a baffle inside, and each baffle has a limiting groove on its exterior. Limiting blocks are fixedly installed at both ends of the fixed plate. The limiting blocks are slidably connected to the inside of the limiting groove. Each groove has a recess inside, and the baffle is slidably connected to the inside of the recess.

[0010] Preferably, a spring is fixedly connected inside each groove, and a baffle is fixedly connected to the outside of the spring.

[0011] Preferably, each groove has two built-in slots inside, and each built-in slot has a built-in plate slidably connected inside, with the two built-in plates fixedly connected to both ends of the baffle.

[0012] (III) Beneficial Effects

[0013] 1. By setting up connectors and using limit screws, when installing the guardrail, the connecting block can be pulled to allow the connector to enter the sliding groove. The guardrail can then be placed between two connectors and connected to them. After the connector is moved out of the sliding groove, the fixing plate is placed to fit against the connecting block to fix it. Finally, the nut is connected to the limit screw. Therefore, when installing a new guardrail, the connector being located inside the sliding groove does not affect the installation of the guardrail. At the same time, when fixing four connectors, two nuts are used in conjunction with the limit screw to fix them, reducing the original threaded connection structure, thereby achieving rapid assembly of the guardrail and improving the replacement efficiency of the guardrail.

[0014] 2. By setting up a baffle and cooperating with a spring, when the connector is connected to the guardrail, the baffle slides downward under the action of the spring. At this time, the baffle is located between the two connecting blocks, and both ends of the baffle are respectively attached to the outside of the two connecting blocks. At this time, the connecting blocks are blocked by the baffle and cannot move. With the double protection of the baffle and the fixed plate, the probability of the connector moving when it is connected to the guardrail is reduced. Attached Figure Description

[0021] This application provides a highway guardrail that can be quickly assembled, effectively solving the technical problem that when a guardrail is inserted between two supports 1, the connecting parts 2 need to be disassembled, and one guardrail needs to be connected to four connecting parts 2, which leads to a cumbersome replacement process and reduces the replacement efficiency of the guardrail.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution in this application embodiment effectively solves the technical problem that when a guardrail is inserted between two supports 1, the connecting piece 2 needs to be disassembled, and one guardrail needs to be connected to four connecting pieces 2, which leads to a cumbersome replacement process and reduces the replacement efficiency of the guardrail. The overall idea is as follows:

[0024] To address the problems existing in the prior art, this utility model provides a highway guardrail that can be quickly assembled. The quickly assembled highway guardrail includes a bracket 1, with two connectors 2 at both ends of the bracket 1. Each connector 2 has a connecting block 3 fixedly installed on its exterior. The connecting block 3 is L-shaped. A connecting mechanism is provided on the exterior of the bracket 1, including a limiting screw 4, a fixing plate 5, and a nut 6. The limiting screw 4 is fixedly installed on the exterior of the bracket 1, the fixing plate 5 is slidably connected to the exterior of the limiting screw 4, and the nut 6 is threadedly connected to the exterior of the limiting screw 4. Two sliding grooves 7 are formed on the exterior of the bracket 1, and the connecting block 3 is slidably connected to the interior of the sliding grooves 7. The two ends of the fixing plate 5 are respectively slidably connected to the two... Inside the slide groove 7, the fixing plate 5 is concave, and the connecting block 3 is attached to the outside of the fixing plate 5. By setting the connecting piece 2 and cooperating with the limiting screw 4, when the guardrail is installed, the connecting block 3 can be pulled to make the connecting piece 2 enter the interior of the slide groove 7. At this time, the fixing plate 5 is attached to the connecting block 3 to fix the connecting block 3. Then, the nut 6 is connected to the limiting screw 4. Therefore, when installing a new guardrail, the connecting piece 2 is located inside the slide groove 7 and does not affect the installation of the guardrail. At the same time, when fixing four connecting pieces 2, they are fixed by two nuts 6 and the limiting screw 4, reducing the original threaded connection structure, thereby realizing the rapid assembly of the guardrail and improving the replacement efficiency of the guardrail.

[0025] The fixing plate 5 has a through hole 8 on its outside. The fixing plate 5 is slidably connected to the outside of the limiting screw 4 through the through hole 8, which is the connection structure between the fixing plate 5 and the limiting screw 4.

[0026] Each slide groove 7 has a baffle 9 inside, and each baffle 9 has a limiting groove 10 on its outside. Limiting blocks 15 are fixedly installed at both ends of the fixing plate 5. The baffle 9 is located between two connecting blocks 3. The limiting blocks 15 are slidably connected inside the limiting groove 10. Each slide groove 7 has a recess 11 inside, and the baffle 9 is slidably connected inside the recess 11. A spring 12 is fixedly connected inside each recess 11, and the baffle 9 is fixedly connected to the outside of the spring 12. The spring 12 provides support for the baffle 9. Each recess 11 has two internal grooves 13 inside. The groove 13 is slidably connected to an internal plate 14. The two internal plates 14 are fixedly connected to the two ends of the baffle 9 to prevent the connection between the baffle 9 and the groove 11 from being disengaged. By setting the baffle 9 and cooperating with the spring 12, when the connector 2 is connected to the guardrail, the baffle 9 slides downward under the action of the spring 12. At this time, the baffle 9 is located between the two connecting blocks 3, and the two ends of the baffle 9 are respectively attached to the outside of the two connecting blocks 3. At this time, the connecting blocks 3 are blocked by the baffle 9 and cannot move. With the double protection of the baffle 9 and the fixed plate 5, the probability of the connector 2 moving when connected to the guardrail is reduced.

[0027] Working principle:

[0028] First, by setting up connector 2 and cooperating with limit screw 4, when the guardrail is disassembled, rotate nut 6 to disengage the connection between nut 6 and limit screw 4. At this time, pull fixed plate 5 to disengage the connection between fixed plate 5 and slide groove 7. At this time, fixed plate 5 is no longer in contact with the surface of connecting block 3. At this time, move baffle 9 upward to enter the interior of groove 11. At this time, spring 12 is compressed. At this time, push connecting block 3 to disengage connector 2 into slide groove 7 and disconnect it from the guardrail. After all four connectors 2 of the guardrail have been disassembled, the guardrail can be disassembled.

[0029] The second step is to install the guardrail. First, place the guardrail between the two brackets 1. Then, push the connecting block 3 to make the connecting piece 2 snap into the outside of the guardrail. At this time, the baffle 9 slides downward under the action of the spring 12. Then, insert both ends of the fixing plate 5 into the inside of the sliding groove 7. At this time, the limiting block 15 slides into the inside of the limiting groove 10 to prevent the baffle 9 from moving upward. At the same time, the fixing plate 5 slides into the outside of the limiting screw 4 through the through hole 8. At this time, the connecting block 3 is attached to the outside of the fixing plate 5 and cannot move. Then, thread the nut 6 onto the outside of the limiting screw 4 until the nut 6 is attached to the outside of the fixing plate 5. At this time, the fixing plate 5 is fixed, and the guardrail installation is completed.

[0030] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
