Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1

[0027] Reference Figure 1 , a road marking thickness gauge, which is used in the field of measuring instruments, includes: an outer plate, an inner plate and a fixing component.

[0028] The outer panel is composed of a lower outer panel 1 and an upper outer panel 2. The upper outer panel 2 is rotatably arranged on the top of the lower outer panel 1 so that the two can rotate relative to each other for easy folding and storage.

[0029] Reference Figure 2-4 The inner plate measures the thickness of the marking line through the displacement difference between the inner plate and the outer plate, and specifically includes a lower measuring plate 5 and an upper measuring plate 10. The lower measuring plate 5 is slidably set inside the lower outer plate 1, and the upper measuring plate 10 is slidably set inside the upper outer plate 2. The top of the lower measuring plate 5 cooperates with the bottom of the upper measuring plate 10. A concave surface 4 is provided on one side of the bottom of the lower outer plate 1. The bottom end of the lower measuring plate 5 extends to the inside of the concave surface 4 and is flush with the bottom of the lower outer plate 1, ensuring that when the bottom of the lower outer plate 1 contacts the road surface, the lower measuring plate 5 can contact the marking line. A measuring hole 22 is provided on one side of the upper outer plate 2, and a scale plate 23 is fixedly provided on one side of the upper measuring plate 10, and the scale plate 23 is located inside the measuring hole 22. A scale line 24 is provided on one side of the upper outer plate 2, and the scale plate 23 cooperates with the scale line 24. By reading the relative position of the two, the thickness of the marking line can be accurately measured.

[0030] Specifically, the lower outer plate 1 is placed next to the marking line, and the lower measuring plate 5 is located above the marking line. When the bottom end of the lower outer plate 1 touches the ground, the bottom end of the lower measuring plate 5 will touch the marking line and move it upward. The lower measuring plate 5 drives the upper measuring plate 10 to move, and the upper measuring plate 10 drives the scale plate 23 to move. By observing the positional relationship between the scale plate 23 and the scale line 24, the thickness measurement effect is achieved. There is no need for frequent squatting operations, and the operation is convenient.

[0031] Example 2

[0032] refer to Figure 4-5, improved on the basis of Example 1: the fixing assembly is used to fix the lower outer plate 1 and the upper outer plate 2 to ensure the stability of the instrument structure during measurement. The fixing assembly is arranged inside the upper outer plate 2, and the specific structure includes components such as the insertion rod 11, the sliding hole 12, the slot 13, the fixing plate 16, the movable groove 20, the fixing rod 15, the fixing groove 14, the tension spring 19 and the auxiliary plate 18. The insertion rod 11 is slidably arranged inside the sliding hole 12, and the bottom end of the insertion rod 11 cooperates with the slot 13 to lock the relative position of the lower outer plate 1 and the upper outer plate 2 so that they cannot rotate. The fixing plate 16 is located inside the movable groove 20, and the surface of the insertion rod 11 is provided with a movable hole 21, and the fixing plate 16 is slidably arranged inside the movable hole 21. The surface of the fixing plate 16 is provided with a side hole 17, and the inner wall of the movable hole 21 is fixedly provided with an auxiliary plate 18. A plurality of tension springs 19 are fixedly provided between the side hole 17 and the auxiliary plate 18 to provide elastic force for the fixing plate 16 to reset. Fixed rods 15 are fixedly provided at the top and bottom of one side of the fixed plate 16, and fixed grooves 14 are opened at the top and bottom of the inner wall of one side of the movable groove 20. The two fixed rods 15 are respectively matched with the two fixed grooves 14 to lock the position of the fixed plate 16 and then lock the position of the insertion rod 11.

[0033] Specifically, when the thickness gauge needs to be folded and stored, it is only necessary to press the fixing plate 16, and the fixing plate 16 drives the fixing rod 15 to move so that it disengages from the inside of the fixing groove 14. At this time, the fixing plate 16 can be moved upward, and the fixing plate 16 drives the insertion rod 11 to move so that it disengages from the inside of the slot 13. At this time, the fixation between the lower outer panel 1 and the upper outer panel 2 will be released, and then the upper outer panel 2 will be rotated one hundred and eighty degrees for folding, and then the insertion rod 11 is moved to insert its top end into the inside of the socket 3, thereby achieving fixation after folding, and realizing double fixation in the unfolded state and the folded state, so as to facilitate actual use and storage and transportation.
