Detailed Implementation

[0018] The following will be combined with the appendix Figures 1-4 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly explained. The described embodiments are obviously only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figures 1 to 4The present invention discloses a paint film thickness detection device, including a paint film thickness meter body 1, a display panel 2 on the surface of the paint film thickness meter body 1, a button 3 on the surface of the paint film thickness meter body 1, and a detection contact block 4 at the bottom of the paint film thickness meter body 1. When detecting the paint on the surface of a vehicle, the power of the paint film thickness meter should be checked in advance to ensure that the power is sufficient to avoid affecting the use due to insufficient power during the measurement process.

[0020] Specifically, a first spring damping rod 5 and a second spring damping rod 6 are fixedly connected to the side wall of the paint film measuring instrument body 1. The first spring damping rod 5 and the second spring damping rod 6 are located at the left and right ends of the detection contact block 4, respectively. The first spring damping rod 5 and the second spring damping rod 6, in cooperation with the protective plate 7, protect the detection contact block 4 from being damaged by impact from the ground or hard objects.

[0021] Specifically, the first spring damping rod 5 and the second spring damping rod 6 are fixedly connected to the left and right ends of the protective plate 7, respectively. The middle area of ​​the protective plate 7 is hollow, and the detection contact block 4 is located directly above the hollow area of ​​the protective plate 7. Then, the user holds the elastic airbag 12 by hand, which drives the paint film measuring instrument body 1 to move as a whole so that the rubber column 8 on the protective plate 7 contacts the paint on the vehicle surface. The user pushes the paint film measuring instrument body 1 downward to move and compress the first spring damping rod 5 and the second spring damping rod 6. The paint film measuring instrument body 1 drives the detection contact block 4 to contact the vehicle surface. The side wall of the first spring damping rod 5 near the area of ​​the paint film measuring instrument body 1 is recessed inward to form a groove.

[0022] Specifically, a pull rope 13 is fixedly connected to the bottom of the protective plate 7. When the protective plate 7 is not in use, a pulling force can be applied to the pull rope 13, which will drive the protective plate 7 to move downward. The pull rope 13 has a Y-shaped structure, which exposes the detection contact block 4. Then, the pull rope 13 is tied to the groove on the side wall of the first spring damping rod 5, which can restrict the protective plate 7.

[0023] Specifically, multiple sets of rubber columns 8 are fixedly connected to the side wall of the protective plate 7 away from the detection contact block 4 to prevent the protective plate 7 from directly contacting the vehicle paint surface. When the detection contact block 4 contacts the vehicle paint surface, there is a certain gap between the protective plate 7 and the paint, which facilitates the air transmitted from the nozzle 10 to flow outward through the gap.

[0024] Specifically, the protective plate 7 has a hollowed-out flow channel 9. Multiple sets of nozzles 10 are embedded in the inner wall of the protective plate 7. The angle between the nozzles 10 and the protective plate 7 is set at 45 to 60 degrees to facilitate the delivery of air to the paint surface of the vehicle. The nozzles 10 are connected to the flow channel 9. A filter screen is provided at the end of the nozzles 10 away from the flow channel 9. The protective plate 7 is fixedly connected to one end of the telescopic tube 11. The telescopic tube 11 is connected to the flow channel 9 in the protective plate 7. The other end of the telescopic tube 11 is connected to the elastic airbag 12. The elastic airbag 12 is fixedly connected to the end of the paint film analyzer body 1 away from the detection contact block 4. When the protective plate 7 comes into contact with the paint of the vehicle, the elastic airbag 12 can be pre-compressed. The air inside the elastic airbag 12 flows into the telescopic tube 11 and then enters the flow channel 9 through the telescopic tube 11. Subsequently, the air is transmitted to the nozzles 10 through the flow channel 9. The nozzles 10 blow the air toward the paint surface to be tested. Then, the detection contact block 4 tests the paint on the surface of the vehicle.
