[0001] The utility model belongs to the technical field of guardrails, and in particular relates to a safety guardrail that is convenient to store. Background Art

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. In daily life, the use of safety guardrails is often involved.

[0003] Generally, the existing safety guardrails are inconvenient to store and use during use, thereby reducing the use effect and work efficiency of the device.

[0004] To this end, we propose a safety guardrail that is easy to store to solve the above problems. Utility Model Content

[0005] The purpose of the present application is to solve the problem in the prior art that the safety guardrail is inconvenient to store during use, and to propose a safety guardrail that is easy to store.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a safety guardrail that is easy to store, characterized in that it includes a base, a connecting plate parallel to the base, a plurality of first brackets are fixedly arranged on the upper surface of the base, and a plurality of second brackets corresponding to the first brackets are fixedly arranged on the lower surface of the connecting plate;

[0007] The first bracket and the second bracket are connected through an outer cylinder and an inner cylinder which are arranged concentrically, the inner cylinder is inserted into the outer cylinder, the lower end of the outer cylinder is rotatably arranged on the two side plates of the first bracket through a rotating shaft which is fixedly connected thereto, and the upper end of the inner cylinder is rotatably arranged on the second bracket through a rotating shaft which is fixedly connected thereto;

[0008] The outer cylinder and the inner cylinder are connected by bolts, and the outer cylinder and the inner cylinder are both provided with a plurality of mounting holes matched with the bolts;

[0009] It also includes a locking screw that passes through the first bracket and the outer tube. The locking screw is a bolt, so that the outer tube can be fixed and its rotation can be restricted.

[0010] Furthermore, a limiting plate is disposed on one side of the first bracket and the second bracket, and the limiting plates of the first bracket and the second bracket are located on different sides. Through the limiting plate, when the guardrail is stored, the outer tube and the inner tube can only rotate in one direction, preferably making the outer tube and the inner tube parallel to the base.

[0011] Furthermore, a stepper motor is fixedly arranged on the base, and the motor shaft of the stepper motor is concentric with the rotation axis of any of the outer cylinders and is fixed on the rotation axis. The stepper motor can be easily stored.

[0012] Furthermore, a support base is fixedly connected to the outer surface of the stepper motor, and the support base is fixed on the base.

[0013] Furthermore, any end of the rotating shaft on the first bracket extends out of the first bracket and a connecting plate is fixedly arranged on the extending end, and a handle is fixedly arranged on the connecting plate. The outer surface of the handle is evenly distributed with a plurality of anti-slip grooves in the circumferential direction.

[0014] Furthermore, a telescopic rod is concentrically arranged inside the outer tube, the fixed end of the telescopic rod is fixedly arranged on the bottom wall of the outer tube, and the movable end of the telescopic rod is fixed to the lower end of the inner tube. The telescopic rod can be an electric push rod, and the distance between the base and the connecting plate can be increased by the telescopic rod, thereby increasing the height of the guardrail.

[0015] Furthermore, the movable end of the telescopic rod is connected to the inner cylinder via a spring, and the spring has a certain buffering effect.

[0016] Furthermore, a guide column is coaxially arranged inside the spring, and a guide hole cooperating with the guide column is arranged at the lower end of the inner cylinder.

[0017] Furthermore, the base is provided with a plurality of reserved holes, and can be installed on the ground by means of expansion bolts.

[0018] To summarize, the technical effects and advantages of the present application are as follows: a stepper motor is used to drive the outer cylinder on one of the first brackets to rotate. Since the outer cylinder and the inner cylinder are fixed by bolts, the rotation of the outer cylinder drives the inner cylinder to rotate, and the inner cylinder drives the connecting plate to rotate. The connecting plate is lowered, thereby realizing the storage of the guardrail; the inner cylinder is used to slide inside the outer cylinder to realize the adjustment of the height of the guardrail, thereby improving the application range of the guardrail.
