Abstract
The utility model discloses an attached type micro strain sensor, it includes the sensor main part, the middle part of sensor main part top surface is provided with the measuring terminal, the one end of sensor main part top surface is provided with the supporting shoe, the last installation through-hole of having seted up of sensor main part, the installation through-hole is located between supporting shoe and the measuring terminal. Provided is an attached micro-strain sensor, which solves the problems of complex installation and poor sensitivity of the existing sensor.
Description
Technical Field
The utility model relates to an attached type micro-strain sensor belongs to sensor technical field.
Background
At present, the national and social security quality problems of dam, bridge and railway construction are more and more emphasized, the security detection technology is widely applied, and the popularization and use of various detection sensors bring qualitative leap for the security detection technology. However, when the existing pressure sensor is used in practice, the installation mode and the structure of the existing pressure sensor on a measured object are too complex, the installation is complicated, time and labor are wasted, the cost is increased, and the sensitivity of the pressure sensor is reduced.
Disclosure of Invention
The utility model aims to solve the technical problem that, overcome prior art not enough, provide an attached type microstrain sensor, solve the problem that current sensor installation is complicated and sensitivity is poor.
In order to solve the technical problem, the technical scheme of the utility model is that:
an attached type micro-strain sensor comprises a sensor main body, wherein a measuring end is arranged in the middle of the top surface of the sensor main body, a supporting block is arranged at one end of the top surface of the sensor main body, and a mounting through hole is formed in the sensor main body and is located between the supporting block and the measuring end.
Furthermore, the connecting part of the mounting through hole and the bottom surface of the sensor main body is a counter bore.
Furthermore, an avoiding groove is formed in the side wall, close to the mounting through hole, of the supporting block.
Further, the other end of the sensor main body is provided with a signal wire joint.
Further, the supporting block and the measuring end are the same in height.
After the technical scheme is adopted, the utility model discloses a screw is with sensor body direct mount on the measured object, and fixed mode convenient and fast more, the installation is simple, has reduced installation cost. The utility model discloses a small, light in weight, measuring range is wide, and sensitivity is higher.
Drawings
Fig. 1 is a top view of an attached microstrain sensor of the present invention;
fig. 2 is an internal structural schematic diagram of an attached type micro strain sensor of the present invention.
Detailed Description
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.
As shown in fig. 1 and 2, an attached type micro-strain sensor comprises a sensor body 1, a measuring end 2 is arranged in the middle of the top surface of the sensor body 1, a supporting block 3 is arranged at one end of the top surface of the sensor body 1, a mounting through hole 4 is formed in the sensor body 1, and the mounting through hole 4 is located between the supporting block 3 and the measuring end 2. The utility model discloses a sensor main part 1 can directly block on the testee, supports on the surface of testee through supporting shoe 3, and the reuse screw passes installation through-hole 4 fixed, and supporting shoe 3 is the same with the height of measuring terminal 2, makes supporting shoe 3 and measuring terminal 2 be located same water flat line, and measuring terminal 2 is direct to be contacted with the testee, measures sensitive accuracy more. When the object to be measured is stressed, deformation is generated, and the quartz crystal in the sensor is changed to generate electric charge, so that the micro-strain of the object to be measured can be sensitively detected.
As shown in FIG. 2, the connecting position of the mounting through hole 4 and the bottom surface of the sensor body 1 is a counter bore 41 for mounting a flat head screw, so that the connection is smoother and more stable.
As shown in fig. 1, the side wall of the support block 3 near the mounting through hole 4 is provided with an avoiding groove 31, and the avoiding groove 31 is used for avoiding a screw.
As shown in fig. 1, the other end of the sensor body 1 is provided with a signal line connector 11, which is connected with a signal line and transmits measurement data to a detection device.
The above-mentioned embodiments further explain in detail the technical problems, technical solutions and advantages solved by the present invention, and it should be understood that the above only is a specific embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
