Description

Technical Field

[0001] This utility model belongs to the field of highway guardrail technology, specifically relating to a locking type highway guardrail. Background Technology

[0002] Highway guardrails are strip-shaped protective energy-absorbing structures installed on the outer side of the driving lane or in the central divider of a highway. They are usually made of materials such as steel and aluminum alloys and are designed to clearly indicate and convey traffic information, maintain traffic order, and absorb collision energy when a vehicle loses control by blocking, deforming itself, or climbing the vehicle, thereby stopping the vehicle and reducing the degree of injury to the driver and passengers.

[0003] The patent CN201095731Y discloses a locking type highway guardrail. This patent designs the integrated horizontal bar as a separate structure and adds lock heads and lock bodies to the ends of the two separate horizontal bars to achieve locking installation and quick disassembly and assembly. However, the overall connection strength of this connection method of the above patent is insufficient. Once it is hit by a car or pedestrian, it is very easy to separate and cannot achieve the purpose of effective protection. Therefore, it has great limitations in practical use and has room for improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a locking type highway guardrail to solve the problems of insufficient connection strength and poor protective effect of existing locking type highway guardrails mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a locking type highway guardrail, comprising symmetrically arranged main support rods; two crossbars, arranged inside the main support rods, with an end plate installed at the end of each crossbar; a locking assembly is provided at the connection between the end plate and the main support rod, the locking assembly comprising: a connector, which is connected through the end plate, and one end of the connector is screwed into the interior of the main support rod; and a clamping member, which is sleeved on the connector and located between the connector and the end plate, and clamps against the end plate in the direction of the limiting bolt, thereby achieving the purpose of fastening the end plate.

[0006] Preferably, the bottom surface of the end plate has a connecting hole, and the top of the connecting hole has a deformation groove. The connector is a limiting bolt that passes through the connecting hole. The inner side of the main support rod has a screw hole for one end of the limiting bolt to be screwed in. The connecting hole is fitted onto the limiting bolt. During installation, the crossbar is pressed down directly, so that the connecting hole on the end plate is fitted onto the limiting bolt, thereby completing the installation from top to bottom.

[0007] Preferably, a deformation groove is provided at the top of the connecting hole. The deformation groove is vertically arranged and located directly above the connecting hole. When the connecting hole is inserted into the limiting bolt, it will force the deformation groove to deform and increase the opening area of ​​the connecting hole, thereby achieving normal installation.

[0008] Preferably, the clamping member includes a clamping plate with a through hole on its surface for the limit bolt to pass through. The clamping plate abuts against the other end of the limit bolt, and a disc spring is provided between them. In the locking installation of the main support rod and the crossbar, the end plate is first inserted between the clamping plate and the main support rod. At this time, the end plate will abut against the clamping plate, and the reaction force of the clamping plate will be applied to the disc spring, which will be compressed. When the end plate is sleeved on the limit bolt through the connecting hole, the disc spring will rebound and press the clamping plate against the end plate, thereby completing the limiting clamping.

[0009] Preferably, the longitudinal section of the abutment plate has a U-shaped structure, and the top position of the abutment plate facing the end plate is inclined inward and has a guide portion, which facilitates the insertion of the end plate.

[0010] Preferably, a limiting plate is fixedly provided on the inner side of the main support rod. The limiting plate is sleeved on both sides of the end plate to limit the end plate. The cross-section of the limiting plate is "L" shaped. The limiting plate further limits the end plate. The limiting plate does not contact the crossbar.

[0011] Preferably, multiple connecting rods are also installed on the inner side of the two crossbars, and the connecting rods are hollow cuboid structures.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this utility model, the integrated crossbar structure is retained, and a locking component is added at the connection between the crossbar and the main support rod. Compared with the locking method in the current technology, the locking component has higher stability. Therefore, this improvement can not only ensure quick disassembly and assembly, but also achieve effective protection for pedestrians and vehicles, thus improving the differences in the existing technology. In addition, the locking component has a simple structure, is easy to manufacture and process, and has high practicality. Attached Figure Description

[0025] A locking assembly is provided at the connection between the end plate 104 and the main support rod 100. The locking assembly includes:

[0026] The connector is connected through the end plate 104, and one end of the connector is screwed into the interior of the main support rod 100;

[0027] The clamping member is sleeved on the connector and positioned between the connector and the end plate 104. The clamping member is pressed against the end plate 104 and the limiting bolt 203, thereby achieving the purpose of fastening the end plate 104.

[0028] In this embodiment, preferably, the bottom surface of the end plate 104 is provided with a connecting hole 105, and a deformation groove 106 is provided at the top of the connecting hole 105. The connecting component is a limiting bolt 203 that passes through the connecting hole 105. The inner side of the main support rod 100 is provided with a screw hole for one end of the limiting bolt 203 to be screwed in. The connecting hole 105 is fitted onto the limiting bolt 203. During installation, the crossbar 101 is pressed down directly, so that the connecting hole 105 on the end plate 104 is fitted onto the limiting bolt 203, thereby completing the installation from top to bottom.

[0029] In this embodiment, preferably, a deformation groove 106 is provided at the top of the connecting hole 105. The deformation groove 106 is vertically arranged and is located directly above the connecting hole 105. When the connecting hole 105 is inserted into the limiting bolt 203, the deformation groove 106 will be forced to deform to increase the opening area of ​​the connecting hole 105, thereby achieving normal installation.

[0030] In this embodiment, preferably, the clamping member includes a clamping plate 200. The surface of the clamping plate 200 has a through hole 204 for the limiting bolt 203 to pass through. The clamping plate 200 abuts against the other end of the limiting bolt 203, and a disc spring 202 is also provided between the two. In the locking installation of the main support rod 100 and the crossbar 101, the end plate 104 is first inserted between the clamping plate 200 and the main support rod 100. At this time, the end plate 104 will abut against the clamping plate 200. The reaction force of the clamping plate 200 is applied to the disc spring 202, and the disc spring 202 is compressed. When the end plate 104 is sleeved on the limiting bolt 203 through the connecting hole 105, the disc spring 202 rebounds and presses the clamping plate 200 against the end plate 104, thereby completing the limiting clamping.

[0031] In this embodiment, preferably, the longitudinal section of the abutment plate 200 is U-shaped. The top position of the abutment plate 200 facing the end plate 104 is inclined inward and has a guide portion 201. The guide portion 201 facilitates the insertion of the end plate 104.

[0032] In this embodiment, preferably, a limiting plate 103 is also fixed on the inner side of the main support rod 100. The limiting plate 103 is sleeved on both sides of the end plate 104 to limit the end plate 104. The cross-section of the limiting plate 103 is "L" shaped. The limiting plate 103 further limits the end plate 104. The limiting plate 103 and the crossbar 101 do not contact each other.
