Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Specific example 1: referring to fig. 1-8, a sensor includes a first structure 1, a second structure 2 and a washer 3, the washer 3 is located between the first structure 1 and the second structure 2, the washer 3, the first structure 1 and the second structure 2 are connected together by a bolt and a nut, the first structure 1 has an observation portion 11, the second structure 2 has an elastic portion 21, the washer 3 has a through hole 31, the elastic portion 21 has elasticity, the elastic portion 21, the observation portion 11 and the washer 3 enclose a liquid storage cavity, the position of the elastic portion 21 corresponds to the position of the observation portion 11, and the size of the elastic portion 21 is the same as that of the observation portion 11.
In the initial state, i.e. when no foreign object acts, the elastic part 21 and the observation part 11 are convex, the convex directions of the elastic part 21 and the observation part are opposite, and the convex shape is a hemisphere shape; the contact part of the outer wall of the elastic part is uniformly stressed, the surface curvature is the same, and the adaptability is strong.
The 11 inner walls of observation portion are the colourless frosting, the coloured pollution-free liquid is deposited to liquid storage intracavity portion, for the change of the coloured liquid level in the more clear reflection liquid storage intracavity, use the colourless frosting can clearly observe the liquid level line that the frosting contacted, liquid is coloured liquid promptly, the observer watches from the outside, can see coloured liquid and be full of the frosting, the frosting with coloured liquid promptly becomes coloured, avoided the liquid level for under the observation portion tilt state, the unsafe risk of observation information.
Through-hole 31 size is greater than or equal to the inside maximum dimension of elastic component 21, and through-hole 31 size is greater than or equal to the inside maximum dimension of observation portion 11, when guaranteeing that elastic component 21 takes place extrusion liquid when deformation, and unhindered, elastic component 21 can the maximum emergence deformation, and the stock solution intracavity portion is unimpeded promptly.
When a foreign object acts on the elastic part 21, namely, when the force acts on the elastic part 21, the elastic part 21 deforms, firstly, the deformation motion starts from the surface of the extruded part to the inside of the liquid storage cavity, the colored liquid is extruded on the inner wall of the elastic part 21, the liquid level of the colored liquid rises, then, the observation is carried out through the observation part 11, the observation is carried out from the outer side of the observation part, only the liquid level close to the frosting surface can be seen due to the existence of the frosting surface, the frosting surface in contact with the liquid can become colored, the change degree of the force is reflected according to the degree (the rising degree of the liquid level) that the frosting surface is filled with the liquid color, and therefore, the action and the change degree of.
