AI Technical Summary
The existing road crack detector is not sealed and stored after use, resulting in dust adhering to the surface of the instrument, which accelerates the aging, which is not conducive to long-term use.
A road crack detector including a protective box and a movable seat is designed. The detector body is brought into the protective box through the movable seat and sealed through the baffle to achieve dust protection of the detector body. At the same time, vibration damping seat, friction plate and spring are installed inside to buffer vibration to ensure that the detector is more stable during movement.
It effectively prevents the detector from aging too quickly due to exposure when not in use, and uses vibration reduction measures to ensure that the detector is not damaged by vibration during movement, extending its service life.

When it is necessary to detect road cracks, the support pusher 3 can be manually pushed to move the base 1 in cooperation with the traveling wheels 4 to move the road crack detector to the position where the detection is required. Then, the handle 62 is manually pulled outward to pull the movable seat 6 together with the detector body 8 out of the protection box 2, and the road cracks can be detected through the detector body 8. After the road crack detection is completed, the movable seat 6 can be moved back into the protection box 2, and the baffle 61 can seal the opening on the front side of the protection box 2, so that the detector body 8 can be protected from dust through the protection box 2 to slow down the aging of the detector body 8.
[0021] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the interior of the movable seat 6 is elastically connected with the vibration damping seat 9 through the spring 11, the detector body 8 is fixedly installed on the top of the vibration damping seat 9, and the front and rear sides of the vibration damping seat 9 are symmetrically fixed with limit sliders 91, the limit sliders 91 move along the limit slide grooves provided inside the movable seat 6, and the outer wall of the limit slider 91 is fixedly connected with a friction plate 10, and the friction plate 10 is effectively fitted with the limit slide grooves provided inside the movable seat 6. Three springs 11 are arranged side by side with equal intervals under the vibration damping seat 9, the lower end of the spring 11 is fixedly connected to the bottom of the inner side of the movable seat 6, and the upper end of the vibration damping seat 9 is fixedly connected Connected to the bottom of the vibration-damping seat 9, during the movement of the detector body 8, the base 1 bumps up and down, driving the detector body 8 to vibrate together with the vibration-damping seat 9. At this time, the vibration of the vibration-damping seat 9 can compress the spring 11, and the detector body 8 is buffered by the spring 11. At the same time, the movement of the vibration-damping seat 9 can drive the friction plate 10 and the limiting slide groove inside the movable seat 6 to slide relative to each other, thereby converting the kinetic energy brought by the vibration into heat, reducing the vibration, so that the detector body 8 can be more stable during the movement, and the detector body 8 can be prevented from being damaged due to large vibration during the movement.

In the process of moving the detector body 8, the base 1 bumps up and down, driving the detector body 8 and the vibration-damping seat 9 to vibrate together. At this time, the vibration of the vibration-damping seat 9 can compress the spring 11, and the detector body 8 is buffered by the spring 11. At the same time, the movement of the vibration-damping seat 9 can drive the friction plate 10 and the limiting slide groove inside the movable seat 6 to slide relative to each other, thereby converting the kinetic energy brought by the vibration into heat. The vibration is weakened, so that the detector body 8 can be more stable during the movement, and the detector body 8 can be prevented from being damaged due to the large vibration during the movement. Then, the handle 62 is manually pulled outward to pull the movable seat 6 together with the detector body 8 out of the protective box 2, and the road cracks can be detected through the detector body 8. After the road crack detection is completed, the movable seat 6 can be moved back to the protective box 2, and the baffle 61 can seal the opening on the front side of the protective box 2. The detector body 8 can be protected from dust through the protective box 2, and the aging of the detector body 8 can be slowed down.
