Universal wheels 2 are fixedly connected to the four corners of the bottom of the base 1. The base 1 is moved through the universal wheels 2. A bottom plate 3 is arranged on the top of the base 1. A support column 5 is fixedly connected to the top of the bottom plate 3. The four support columns 5 form a 45-degree angle for the gauge 6, which is convenient for detecting the automobile floor. The top of the support column 5 is fixedly connected to the gauge 6. A floor 7 is arranged on the top of the gauge 6. A slot hole 9 is opened at the bottom of the gauge 6. The welding points of the automobile floor can be detected through the slot hole at the bottom of the gauge 6. The product placement direction is inclined at 45°, and the number of reverse welding points of the product is detected through the opening on the bottom surface of the gauge 6. While reducing the number of gauges 6 and lowering the cost, the flipping action is reduced, and the labor intensity is lowered.

[0034] Refer to Figure 2 and Figure 3, on the outer walls of the front and rear ends of the base 1, evenly distributed connecting blocks 10 are fixedly connected. On the outer walls of the two upper connecting blocks 10, an inclined plate frame 11 is rotatably connected. On the outer walls of the two lower connecting blocks 10, hydraulic cylinders 12 are rotatably connected. The output end of the hydraulic cylinder 12 is rotatably connected to a connecting frame 13, and the connecting frame 13 is rotatably connected to the inclined plate frame 11. At the lower outer wall of the connecting frame 13, a chassis 14 is rotatably connected. At the bottom of the chassis 14, a spring 15 is fixedly connected. One end of the spring 15 is fixedly connected to a telescopic rod 16. There are two connecting blocks 10 at the upper end and four connecting blocks 10 at the lower end. There are rotating shafts on the two middle connecting blocks 10 among the four at the lower end, and there are rotating shafts on the connecting blocks 10 on both sides. A second inclined plate frame rotates on the rotating shafts on both sides. The second inclined plate frame rotates with the connecting frame 13 in the middle section. The upper inclined plate frame 11 is rotatably connected to the rotating rod inside the connecting frame 13. The output end of the hydraulic cylinder 12 rotates with the rotating rod, enabling the connecting frame 13 to be folded. The tail end of the hydraulic cylinder 12 rotates with the middle connecting block 10. The rotating shaft at the lower end of the connecting frame 13 enables the chassis 14 to rotate. Manually rotate the chassis 14. Through the spring 15 and the telescopic rod 16 at the bottom of the chassis 14, it can adapt to different terrains for support, support the overall device, and support during detection.

[0035] Refer to Figure 4 and Figure 5 , a protection component is provided at the bottom of the bottom plate 3. The protection component includes a sliding rod 17. The sliding rod 17 is fixedly connected to the front and rear ends of the base 1. On the top of the left and right sides of the sliding rod 17, first dampers 18 are fixedly connected, and the first dampers 18 are fixedly connected to the bottom of the bottom plate 3. At the middle end of the bottom of the bottom plate 3, evenly distributed support blocks 21 are fixedly connected. Protection plates 8 are fixedly connected to both sides of the bottom plate 3. Bolts 4 are threadedly connected inside both sides of the bottom plate 3 and the base 1. When the device is moving, the bolts 4 are rotated out to shock-absorb the objects at the bottom and protect the inspection tool. When detecting the objects, the bolts 4 are rotated to limit and control between the bottom plate 3 and the base 1 to ensure the accuracy of detection. On the opposite outer walls of the protection plates 8, evenly distributed first fixing blocks 22 are fixedly connected. On the outer walls of the first fixing blocks 22, first inclined plates 24 are rotatably connected. At the bottom of the support block 21, an inclined rod 20 is rotatably connected. At the bottom of the inclined rod 20, a sliding block 19 is rotatably connected, and the sliding block 19 is slidably connected to the outer circle of the sliding rod 17. A return spring 33 is sleeved on the middle outer circle of the sliding rod 17, and the return spring 33 is fixedly connected to the sliding block 19. When the bolts 4 are rotated out and during movement, the bottom plate 3 is pressed downward. Through the first dampers 18 on both sides for buffering, at the same time, the support block 21 moves downward, driving the inclined rod 20 to rotate and pressing the sliding block 19, causing the sliding block 19 to slide on the outer circle of the sliding rod 17 and pressing the return spring 33 for buffering. Through the limit blocks on both sides for limit control, the inspection tool 6 is protected.

[0036] Refer to Figure 4And Figure 5 On the outer wall of the middle end of the back side of the protection plate 8, second dampers 28 are fixedly connected. One end of the second damper 28 is fixedly connected with a fixed disk 25. One side of the fixed disk 25 is fixedly connected with a third damper 29.

The inner walls of the front and rear ends of the sliding groove 26 are both slidably connected with sliders 32. The inner walls of the front and rear ends of the fixed disk 25 are both fixedly connected with damping springs 27. One end of the damping spring 27 is fixedly connected with a slider 32. The slider 32 is rotatably connected with a first inclined plate 24. On the opposite outer wall of the buffer plate 23, uniformly distributed second fixing blocks 31 are fixedly connected. The outer wall of the second fixing block 31 is rotatably connected with a second inclined plate 30. The second inclined plate 30 is rotatably connected with the slider 32. When the buffer plate 23 is stressed, the third damper 29 squeezes the fixed disk 25. The fixed disk 25 squeezes and buffers the second damper 28, so that the second fixing block 31 squeezes the second inclined plate 30, causing the slider 32 to slide on the inner wall of the sliding groove 26, squeezing the damping spring 27, driving the first inclined plate 24 to rotate, and supporting the first inclined plate 24 through the first fixing block 22 to buffer the force, protect the inspection tool, and improve the service life of the inspection tool.

[0037] Working principle: Place the floor 7 into the inspection tool 6. Drive the upper and lower inclined plate frames 11 to rotate through the hydraulic cylinder 12, so that the connecting frame 13 rotates. Manually place the chassis 14 on the ground and support it through the bottom spring 15 and the telescopic rod 16 to stabilize the device. Rotate the bolt 4 into the bottom plate 3 and the base 1 for positioning. The welding points of the automotive floor can be detected through the slot holes at the bottom of the inspection tool 6. Tilt the product placement direction by 45°. Detect the number of reverse side welding points of the product through the opening on the bottom surface of the inspection tool 6. When detecting the floor 7 and after the detection, when the device needs to be moved, rotate the bolt 4 out. When moving, the bottom plate 3 is pressed downward and buffered by the first dampers 18 on both sides. At the same time, the support block 21 moves downward, driving the inclined rod 20 to rotate, squeezing the sliding block 19, so that the sliding block 19 slides on the outer ring of the sliding rod 17, squeezing the return spring 33 for buffering. The inspection tool 6 is protected through the limit control of the limit blocks on both sides. When the front and rear ends of the device encounter bumps, the buffer plate 23 is stressed, so that the third damper 29 squeezes the fixed disk 25. The fixed disk 25 squeezes and buffers the second damper 28, so that the second fixing block 31 squeezes the second inclined plate 30, causing the slider 32 to slide on the inner wall of the sliding groove 26, squeezing the damping spring 27, driving the first inclined plate 24 to rotate, and supporting the first inclined plate 24 through the first fixing block 22 to buffer the force, protect the inspection tool, and improve the service life of the inspection tool.
