[0002] An extensometer is an instrument for measuring the linear deformation between two points of a component and other objects. The clamping arms of the extensometer include an upper arm and a lower arm. During the use of the AE202B type extensometer, since the working state of the extensometer is not easy to detect, the situation often occurs that the clamping arms of the extensometer are in a clamped state and then directly pushed into the testing machine, resulting in the collision between the clamping arms and the specimen, causing the deformation of other components such as the damage of the extensometer spring piece, thus damaging the extensometer, increasing the production cost and delaying the production progress.

[0003] To solve the above problems, the patent document CN206906135U discloses an extensometer auxiliary limiting device, which includes symmetric left and right limiting members. Vertical grooves are formed at the front ends of the left and right limiting members. After the vertical grooves of the left and right limiting members face each other, a specimen clamping groove is formed. Horizontal grooves are formed on the inner walls of the left and right limiting members. After the horizontal grooves of the left and right limiting members face each other, a thimble groove is formed. The left and right limiting members are fixedly installed through pins, but the above problems cannot be solved. Summary of the Utility Model

Detailed implementation mode

[0019] The following is a more detailed description of the specific implementation mode of the present invention with reference to the accompanying drawings through the description of the embodiments, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and contribute to its implementation.

[0020] Figure 1 is a schematic structural diagram of the extensometer working state indicating device in the embodiment of the present invention; Figure 2 is a schematic structural diagram of the extensometer working state indicating device in the front view direction in the embodiment of the present invention.

[0021] As Figure 1 and Figure 2 shown, the extensometer working state indicating device provided by the present invention includes a housing 10, an induction component 20 and an indicating component 30.

[0022] The housing 10 is arranged on the extensometer. There is a movable slot 11 on the housing 10. The movable slot 11 is located at the lower arm of the extensometer and is in a long strip shape.

[0023] The induction component 20 is arranged on the housing 10 and is connected to the lower arm of the extensometer.

[0024] The induction component 20 includes a support block 21 and a movable rod 22. The support block 21 is arranged on the housing 10 and is located on one side of the movable slot 11. The movable rod 22 is movably arranged in the movable slot 11. One end of the movable rod 22 is connected to the lower arm, and the other end passes through the movable slot 11. During the working process of the extensometer, the lower arm will move with the working state of the extensometer, thereby driving the movable rod 22 to slide in the movable slot 11.

[0025] There is a connecting plate 211 on the support block 21. The side of the connecting plate 211 away from the support block 21 is connected to a fixing plate 212. There is a fixing hole 2121 on the fixing plate 212. There is a screw 12 on the housing 10. One end of the screw 12 is arranged on the housing 10. The screw 12 passes through the fixing hole 2121. A nut is screwed on the screw 12. By tightening the nut, the support block 21 is fixed on the housing 10.

[0026] The indicating assembly 30 includes an indicator light 31 and a switch 32. The switch 32 is connected to the indicator light 31 and can control the indicator light 31 to light up or turn off. A mounting plate 213 is provided on the support block 21. The mounting plate 213 is located on the side of the support block 21 away from the connecting plate 211. The indicator light 31 is arranged on the mounting plate 213. The switch 32 is arranged on the mounting plate 213 and is located on the side close to the movable rod 22. The switch 32 is a pressing switch. When the movable rod 22 presses the switch 32, the indicator light 31 lights up; when the movable rod 22 releases the switch 32, the indicator light 31 turns off.

[0027] When the extensometer is in the clamped state, the lower arm drives the movable rod 22 to move away from the indicator light 31, away from the switch 32, and the indicator light 31 is turned off. When the extensometer is in the relaxed state, the lower arm drives the movable rod 22 to move towards the indicator light 31, close to the switch 32, until the extensometer is completely relaxed, the movable rod 22 presses the switch 32, and the indicator light 31 is lit, thereby reminding the operator that the extensometer has been completely relaxed and the next operation can be performed; when the indicator light 31 is not lit, it can remind the operator that the clamping arm of the extensometer is still in the clamped state and the next operation cannot be performed, thereby avoiding damage to the extensometer, improving production safety, and reducing production costs.

[0028] The sensing component 20 also includes a spring 23, one end of the spring 23 is connected to the screw rod 12, and the other end of the spring 23 is connected to the movable rod 22. The spring 23 is in a stretched state and can tighten the movable rod 22 during the movement of the movable rod 22, thereby preventing the movable rod 22 from accidentally touching the switch 32, thereby improving the reliability of the extensometer working status indicating device provided by the utility model, and can further ensure that the extensometer working status indicating device provided by the utility model can assist the operator to know the working status of the extensometer, avoid starting the test when the extensometer is in a clamped state, and avoid damage to the extensometer.
