They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0023] According to an embodiment of the utility model, a pre-embedded fire retardant coating type thin film stress sensor is provided.

[0024] Embodiment 1;

[0025] like Figure 1 and Figure 2 As shown, according to the embedded fire retardant coating type thin film stress sensor of the embodiment of the utility model, it includes a sensor 1 and a buffer mechanism arranged on the outer surface of the sensor 1, the buffer mechanism is provided with a coating layer 2 outside, the coating layer 2 includes a symmetrically arranged fire-resistant layer 3 and a protective layer 4 arranged between two groups of the fire-resistant layers 3, the protective layer 4 includes a symmetrically arranged anti-corrosion layer 5, a buffer layer 6 is provided at one end of the two groups of the anti-corrosion layers 5 close to each other, and a wear-resistant layer 7 is provided at one end of the two groups of the fire-resistant layers 3 away from each other, the wear-resistant layer 7 is composed of an inorganic-organic interpenetrating network polymer, the buffer layer 6 is made of elastic rubber, the anti-corrosion layer 5 is made of epoxy resin, symmetrically arranged handles are provided at both ends of the sensor 1, and a waterproof coating is provided on the surface of the coating layer 2.

[0026] Embodiment 2:

[0027] like Figure 3 As shown, the buffer mechanism includes supports 8 arranged at both ends of the sensor 1, and the top and bottom ends of the two groups of supports 8 are both provided with support plates 9, and the bottom ends of the two groups of support plates 9 are both provided with fixed thorns 10, and any group of supports 8 is provided with spring rods 11 symmetrically arranged up and down, and the ends of the two groups of spring rods 11 that are far away from each other are connected to the support plates 9, and the two ends of the sensor 1 are both provided with slide grooves 12, and the ends of the two groups of supports 8 that are close to each other are both provided with blocks 13 that match the slide grooves 12, and the joints of the supports 8 and the two groups of support plates 9 are provided with reinforcing ribs. In order to facilitate the understanding of the above technical solutions of the utility model, the working principle or operation method of the utility model in the actual process is described in detail below.

[0028] In actual application, when the sensor 1 is subjected to external stress, first, the stress will act on the surface of the sensor 1, and then be dispersed and buffered by the coating layer 2. Since the coating layer 2 adopts a multi-layer structure design, including a fire-resistant layer 3, a protective layer 4 and a wear-resistant layer 7, the material selection between these layers has specific functions and properties, which can effectively improve the fire resistance, protection and wear resistance of the sensor 1. At the same time, the design of the buffer mechanism further enhances the buffering capacity of the sensor 1. When the sensor 1 is subjected to external stress, the spring rod 11 will be compressed, and the stress will be dispersed to the entire buffer mechanism through the action of the support plate 9 and the fixed thorn 10, thereby reducing the direct impact of the stress on the sensor 1 itself. In addition, the setting of the slide groove 12 and the block 13 makes the connection between the buffer mechanism and the sensor 1 tighter, preventing loosening and falling off during the stress transfer process.

[0029] To sum up, with the help of the above-mentioned technical scheme of the utility model, the protection performance of the sensor 1 is improved by setting the coating layer 2 and the related fire-resistant layer 3, protective layer 4, etc., and the possibility of accidents of the sensor 1 is reduced. At the same time, the buffering capacity of the sensor 1 is further improved by setting a buffer mechanism, so that the sensor 1 can better buffer and disperse when subjected to external stress, thereby extending the service life of the sensor 1 and improving its stability. The setting of the waterproof coating further enhances the waterproof performance of the coating layer 2, so that the sensor 1 can work normally even in a humid environment.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
