Return type height limiting rod

Abstract

The invention discloses a return type height limiting rod, which comprises a supporting base, stabilizing bolts, a positioning rod, a limiting bolt, an adjusting rod,limiting holes, an ejector rod, aheight limiting device, warning lamps and warning horns. The top of the supporting base is in bolted connection with two stabilizing bolts. The positioning rod is fixedly connected to the center of the top of the supporting base. The limiting bolt is mounted above the left side of the positioning rod; the adjusting rod is in sliding connection with the positioning rod; the multiple limiting holesare formed in the right side of the adjusting rod in the vertical direction. The ejector rod is fixedly connected to the upper portion of the adjusting rod. The height limiting device is mounted belowthe ejector rod; the four warning lamps are installed at the top of the ejector rod at equal intervals in the horizontal direction. The two warning horns are equidistantly mounted at the two sides ofthe center of the top of the ejector rod. The height limiting rod is simple in structure and reasonable in design, the structure of a traditional height limiting rod is adjusted and improved, and theheight limiting rod is additionally provided with the return typeheight limiting device, so that the height limiting rod can fully warn passing vehicles, and meanwhile damage to the height limiting rod due to the fact that the height of the height limiting rod is too high is reduced.

Description

technical field [0001] The patent of the present invention relates to a return type height limiting rod. Background technique [0002] The function of the height limit pole is generally divided into two types. One is to protect the front facilities, which can also be said to protect the safety of vehicle personnel, such as viaducts, low tunnels, underground parking lots, etc.; the other is to restrict the passage of large vehicles, such as weight-limited roads, open-air Parking lot, village road, etc. [0003] The structure of the existing height-limiting pole is relatively simple, and the warning function is not obvious enough. At the same time, when the vehicle tries to pass, it cannot effectively warn the passing vehicles, and it is easy to cause damage to the height-limiting pole itself. Contents of the invention [0004] The object of the present invention is to provide a return-type height limiting rod to solve the above technical problems. [0005] To achieve the ...
