Description

TECHNICAL FIELD

[0001] The utility model relates to the field of guardrails, especially to a telescopic guardrail capable of being quickly adjusted and fixed. BACKGROUND

[0002] In urban roads, guardrails can separate motor vehicles, non-motor vehicles and pedestrians, allowing them to travel in different lanes, improving road traffic safety and traffic order, and playing an important role in ensuring the safety of drivers and pedestrians.

[0003] According to the search, a telescopic traffic guardrail disclosed in Chinese patent document No. CN215165035U can preset the angle between the guardrails when connecting them, and can also adjust the length of the guardrails when laying them due to the telescopic design of the guardrails, thereby meeting different road usage requirements. The first connecting plate and the second connecting plate are connected to each other to form a fastening sleeve, which can connect the guardrails without the need for tools, making the operation more convenient during use. However, the angle between the two guardrails needs to be adjusted before the guardrails are connected, and after the two guardrails are connected, it is difficult to adjust the angle again due to the setting of the fastening sleeve. The fastening sleeve needs to be removed before adjustment, which is relatively complicated to operate.

[0004] Therefore, in view of the above problem that the angle between the two guardrails needs to be adjusted before the guardrails are connected, and after the two guardrails are connected, it is difficult to adjust the angle again due to the setting of the fastening sleeve, the fastening sleeve needs to be removed before adjustment, which is relatively complicated to operate, a telescopic guardrail capable of being quickly adjusted and fixed can be designed. By setting a hollow sleeve rod, a knob, a threaded rod, a moving block, a connecting rod and a rubber pad, the knob can be rotated to move the rubber pad up and down. When the angle of the guardrail needs to be fixed, the rubber pad is adjusted downward, thereby limiting the rotation of the guardrail. When the angle of the guardrail needs to be adjusted, the rubber pad is adjusted upward, and the angle of the guardrail can be adjusted by the hollow sleeve rod, which is simple and convenient to operate. SUMMARY

[0005] In order to overcome the problem that the angle between the two guardrails needs to be adjusted before the guardrails are connected, and after the two guardrails are connected, it is difficult to adjust the angle again due to the setting of the fastening sleeve, the fastening sleeve needs to be removed before adjustment, which is relatively complicated to operate.

[0006] The technical solution of this utility model is as follows: a retractable guardrail that can be quickly adjusted and fixed, including a mounting rod; it also includes a rotating groove, a hollow sleeve rod, a knob, a threaded rod, a moving block, a connecting rod, and a rubber pad. A rotating groove is provided on the outer side of the mounting rod, and a hollow sleeve rod is rotatably connected inside the rotating groove. A limit groove is provided at the upper inner side of the rotating groove. The upper end of the hollow sleeve rod is set inside the limit groove. An installation groove is provided at the top of the mounting rod, and through grooves are provided on both the left and right sides of the installation groove. The through grooves communicate with the installation groove and the limit groove. A knob is provided at the upper end of the mounting rod, and a threaded rod is connected to the bottom of the knob. The lower end of the threaded rod is installed at the bottom of the installation groove through a bearing. A moving block is provided inside the installation groove, and the moving block is sleeved on the outer side of the threaded rod. The moving block and the threaded rod are threadedly connected. Connecting rods are connected to both the left and right sides of the moving block, and a rubber pad is connected to the bottom of the connecting rod. The rubber pad is located at the upper end of the limit groove.

[0007] Preferably, the opening of the rotating groove facilitates the rotation of the hollow sleeve rod. When the operator rotates the knob, the knob drives the threaded rod to rotate. The moving block, under the action of the threaded rod, moves downward. The moving block then drives the rubber pad downward through the connecting rod, allowing the rubber pad to fit against the upper end of the hollow sleeve rod. At this point, the rubber pad restricts the rotation of the hollow sleeve rod, thus fixing the angle of the guardrail. When the angle of the guardrail needs to be adjusted, the operator only needs to rotate the rubber pad upward by rotating the knob, making the operation simple and convenient.

[0008] Preferably, a second mounting rod is provided on the right side of the first mounting rod, and a folding frame is connected between the hollow sleeve rod and the second mounting rod.

[0009] Preferably, both mounting rod one and mounting rod two have a counterweight plate connected to their bottoms.

[0010] Preferably, a mounting ring plate is rotatably connected to the outer side of the mounting rod, and the mounting ring plate is connected to two parts, one above and one below.

[0011] Preferably, the outer side of the mounting rod two is rotatably connected to the mounting ring plate two, which is connected to two upper and lower mounting ring plates, and the heights of the upper and lower mounting ring plates two are respectively matched with the heights of the upper and lower mounting ring plates one.

[0012] Preferably, a collar is rotatably connected to the end of the mounting ring plate one that is away from the mounting rod one, and a fixing post is connected to the top of the mounting ring plate two.

[0013] Preferably, the upper and lower collars and the fixing post are at the same height, and the collars and the fixing post are matched.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting the rotating groove, hollow sleeve rod, knob, threaded rod, moving block, connecting rod and rubber pad, rotating the knob, the knob can drive the threaded rod to rotate, the moving block is affected by the threaded rod screw thread and can move up and down, the moving block can drive the rubber pad to move up and down through the connecting rod, when the guardrail angle needs to be fixed, adjust the rubber pad downward, the rubber pad can limit the rotation of the hollow sleeve rod, thereby limiting the rotation of the guardrail, when the angle of the guardrail needs to be adjusted, adjust the rubber pad upward, the rubber pad can release the restriction of the hollow sleeve rod, personnel can adjust the angle of the guardrail through the hollow sleeve rod, simple and convenient operation.
