DETAILED DESCRIPTION

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] like Figure 1-3 As shown, the utility model provides a technical solution: a road safety anti-collision guardrail that is easy to disassemble and assemble, comprising a first guardrail 1, a sliding hole 15 is opened on the inner wall of the first guardrail 1, a clamping rod 16 is slidably connected in the sliding hole 15, a pull rod 17 is fixedly connected to the outer wall of the clamping rod 16, the pull rod 17 passes through the sliding hole 15, through the cooperation between the pull rod 17 and the clamping rod 16, the pull rod 17 passes through the sliding hole 15, and the clamping rod 16 can be driven to slide in the sliding hole 15 by pulling the pull rod 17, so that the clamping rod 16 is separated from or clamped with the connecting block 22, which is more convenient and quick when connecting or disassembling;

[0019] A second spring 18 is provided at one end of the clamping rod 16, and a sliding sleeve 19 is sleeved on the outer wall of the second spring 18. Two connecting grooves 20 are provided on one side of the first guardrail 1. Because the second spring 18 is provided, when the pull rod 17 is pulled to drive the clamping rod 16 to disengage from the clamping connection between the connecting block 22, the clamping rod 16 presses the second spring 18 backward. When the pull rod 17 is released, the second spring 18 rebounds, driving the clamping rod 16 to move forward, and can automatically clamp the connecting block 22. The sliding sleeve 19 can limit the second spring 18 to prevent the second spring 18 from being misplaced during the process of being squeezed or rebounding.

[0020] The bottom of the first guardrail 1 and the second guardrail 21 are respectively fixedly connected with two bases 23, and the ends of the first guardrail 1 and the second guardrail 21 away from the bases 23 are respectively provided with two warning lights 24. Due to the bases 23, the anti-collision guardrail is more stable when in use, and the warning function of the warning lights 24 can also be used to find the anti-collision guardrail in the first time in a dark light environment, which plays a better warning role. Two pressing grooves 2 are provided at the end of the first guardrail 1, and a pressing plate 3 is slidably connected in the pressing groove 2. The pressing plate 3 The end of the support 4 is fixedly connected to the support 4, the outer sleeve of the support 4 is connected to a spring 5, the upper part of the support 4 is fixedly connected to a clamping block 6, the upper part of the clamping block 6 is located on the inner wall of the first guardrail 1 and is provided with a clamping groove 7, the clamping block 8 is slidably connected in the clamping groove 7, and a clamping hole 9 is provided below the clamping block 8, a first anti-collision rod 10 is fixedly connected to one side of the clamping block 8, and the first anti-collision rod 10 and the second anti-collision rod 14 are clamped to the second guardrail 21 at one end away from the first guardrail 1, and a connecting block 22 is fixedly connected to one side of the second guardrail 21, and the connecting block There are two connecting blocks 22, and the position of the connecting block 22 corresponds to the position of the connecting groove 20. The connecting block 22 is used to clamp the connecting groove 20 to avoid the inability to connect due to the inconsistency of the height. The number of connecting blocks 22 is two, which is more secure during the connection, and the connection between the first guardrail 1 and the second guardrail 21 is prevented from falling off. The inner wall of the first anti-collision bar 10 is fixedly connected to the upper clamping plate 11, and the upper clamping plate 11 is rotatably connected to the support arm 12 through a pin shaft. The end of the support arm 12 away from the upper clamping plate 11 is connected by a pin shaft. The shaft is rotatably connected to a lower clamping plate 13, and a second anti-collision bar 14 is fixedly connected to one side of the lower clamping plate 13. Through the cooperation between the support arm 12 and the upper clamping plate 11 and the lower clamping plate 13, when the first anti-collision bar 10 and the second anti-collision bar 14 are disengaged from the first guardrail 1 and the second guardrail 21, the first anti-collision bar 10 and the second anti-collision bar 14 are pulled in opposite directions, and the first anti-collision bar 10 and the second anti-collision bar 14 respectively drive the upper clamping plate 11 and the lower clamping plate 13 to rotate through the support arm 12, so that they can be compressed for easy storage.

[0021] The working principle of the utility model is as follows: when using the guardrail, align the clamping block 8 at the end of the first anti-collision rod 10 with the clamping groove 7 and press it inward. Since the end of the clamping block 6 is designed as an arc surface, the clamping block 8 will fit the end of the clamping block 6 and squeeze the clamping block 6 downward, so that the clamping block 6 squeezes the spring 15 downward. When the clamping hole 9 moves to the top of the clamping block 6, the spring 15 rebounds, and the clamping block 6 enters the inside of the clamping hole 9 due to the rebound of the spring 15, so that the first guardrail 1 and the first anti-collision rod 10 are clamped, and the pull rod 17 is pulled, and the pull rod 17 drives the clamping rod 16 to move in the sliding hole 15. The clamping rod 16 squeezes the spring 2 18 during the movement, and the clamping rod 16 moves During the process, the obstruction of the connecting groove 20 is disengaged, and then the connecting block 22 on one side of the second guardrail 21 is aligned with the connecting groove 20. After the connecting block 22 is inserted into the connecting groove 20, the pull rod 17 is released, and the spring 18 rebounds, so that the clamping rod 16 automatically connects the second guardrail 21 and the first guardrail 1 through the connecting block 22. When disassembling, the pressure plate 3 is pressed, and the pressure plate 3 drives the clamping block 6 to move downward to squeeze the spring 18, so that the clamping block 6 is disengaged from the clamping hole 9, so that the first guardrail 1 and the first anti-collision bar 10 are separated, and then the pull rod 17 is pressed, and the pull rod 17 is disengaged from the clamping block 22, so as to separate the connection between the first guardrail 1 and the second guardrail 21.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
