Problems solved by technology
[0005] The problem to be solved by the present invention is to provide a protective width limiting device used in municipal engineering to overcome the purpose of limiting the width of the vehicle when the vehicle is fast or slow after the width of the width limiting device in the prior art is set. If a fast-moving vehicle hits the width limiting device, it will receive a great impact, which will cause great personal injury to the driver and passengers in the vehicle

Embodiment Construction
[0058] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0059] Such as figure 1 , 2 , 3, it includes a fixed shell 1, a trigger mechanism 2, a width-limiting column mechanism 3, an energy storage mechanism 4, a square groove 5, a first accommodation chamber 6, and a second accommodation chamber 7, such as Figure 4 , 5 As shown, wherein the fixed shell 1 is provided with a plurality of square grooves 5 for installing the trigger mechanism 2, and each square groove 5 is equipped with a trigger mechanism 2; as Figure 4 As shown, the fixed housing 1 is also provided with a first accommodation chamber 6 for installing the energy storage mechanism 4 and a second accommodation chamber 7 for installing two symmetrically distribute...

The invention belongs to the technical field of width limiting devices, and in particular relates to a protective width limiting device used in municipal engineering, which includes a fixed shell, a trigger mechanism, etc. The width limiting device in the present invention has a trigger mechanism, and the inside is provided with an identification The non-Newtonian fluid device at the speed of the vehicle, the fast-moving vehicle makes the non-Newtonian fluid device in the trigger mechanism move, and drives the rack connected to it and the gear in the trigger mechanism to move, and the two width-limiting column mechanisms will shorten from the initial state. Fat becomes thinner and taller, the distance between the two width-limiting column mechanisms narrows from the initial state to wide, and fast-moving vehicles pass safely; slow-moving vehicles will deform the non-Newtonian fluid structure in the trigger mechanism, and the non-Newtonian fluid structure The motion bar will not be driven to move, the trigger mechanism will not work, the energy storage mechanism will not work, and the two width-limiting column mechanisms will maintain the initial state of short and fat, so as to achieve the purpose of passing vehicles with a specific width range.
Description
technical field [0001] The invention belongs to the technical field of width limiting devices, in particular to a protective width limiting device used in municipal engineering. Background technique [0002] At present, the existing width-limiting devices mostly use cemented pier or plastic buckets to fill water, set a certain width and place it on the road, and when the vehicle passes by, it will limit the width of the passing vehicle; but when the driver is in the When driving at night, the warning strip on the width-limiting pier will lose its warning effect if it is exposed to the sun for a long time, so that the car will easily hit the width-limiting pier, and the speed will quickly hit the width-limiting pier set on the road. , will cause great bodily harm to the driver and passengers in the car; at the same time, even if the warning strip has a warning effect, the driver will feel tired after driving for a long time or the driver is distracted and does not see the wid...
