Description

Technical Field

[0001] This utility model relates to the field of vehicle paint testing technology, specifically a vehicle paint testing device for used car evaluation. Background Technology

[0002] Paint inspection is crucial for used cars. It's not just about the aesthetic difference between new and old paint; more importantly, paint damage and repairs directly reflect the vehicle's accident history. Therefore, paint inspection is an essential part of the used car buying and selling process. There are many methods and tools for paint inspection. Besides common paint inspection instruments, there is a highly efficient tool: a folding reflector for paint inspection.

[0003] A car paint inspection folding reflector is a tool specifically designed to inspect the condition of a car's paint surface. The striped reflector has alternating black and white stripes, with the black stripes varying in width. Through the design of the alternating black and white stripes, light passes through the striped reflector and is reflected and refracted on the paint surface. By observing whether the direction of the black and white stripes after reflection and refraction matches the shape of the vehicle's sheet metal, one can determine whether there are dents or repair defects on the paint surface.

[0004] Existing striped reflectors all use flexible support ribs to support them. Twisting the support ribs and the reflector together into a figure-eight shape and then folding them together achieves a folding effect. Releasing the ribs allows them to unfold easily. A handle is attached to the support ribs; gripping the handle allows you to move and adjust the relative position and angle of the reflector to the vehicle's paint surface. However, the diameter of existing striped reflectors is relatively large compared to the handle diameter. Because the handle diameter is small, it's inconvenient to apply force, making it difficult to hold and requiring excessive hand strength. Furthermore, when inspecting large SUVs and MPVs, which are tall and wide, standing on a ladder and holding the reflector directly to inspect the roof requires walking around the entire vehicle due to insufficient arm length, making it inconvenient to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a used car paint inspection device for evaluation, which solves the problem of inconvenience in handheld use of existing striped reflectors for paint inspection.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A used car paint inspection device includes a striped reflector with a surrounding edging. A non-closed annular support rib is inserted within the edging. The two ends of the support rib are fixedly connected to the two sides of a fixed plate. The fixed plate is provided with symmetrical support plates, and a rotating tube is provided between the two support plates.

[0008] Both sides of the inside of the rotating tube are movably inserted with chucks. The support plate is fixed with a fixed shaft for the movably inserted chucks. The opposing surfaces of the support plate and the chucks are provided with V-shaped rotating slots. The support plate and the chucks are interlocked with each other through the V-shaped rotating slots.

[0009] The rotating tube has a slot on its middle surface, and a mounting slot is provided at the position of the slot on the rotating tube. The rotating tube is movably engaged with a buckle through the mounting slot. A connecting seat is fixed to the end of the buckle, and a telescopic rod is fixed to the buckle through the connecting seat.

[0010] Limiting plates are movably connected above and below the mounting slot. The opposite ends of the two limiting plates are fixedly connected to the opposite surfaces of the two chucks, and a support spring is installed between the chucks and the mounting slot.

[0011] Preferably, the support plate and the fixing plate are an integral structure.

[0012] Preferably, the mounting slot and the rotating tube are an integral structure, and the inner walls on both sides of the mounting slot are provided with positioning grooves for engaging the buckle.

[0013] Preferably, the limiting plate and the chuck are an integral structure.

[0014] Preferably, the upper and lower surfaces of the mounting slot are both planes, and the opposite surfaces of the two limiting plates are slidably connected to the upper and lower surfaces of the mounting slot, respectively.

[0015] Preferably, the buckle and the connecting seat are an integral structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The supporting rib of this utility model is connected to a fixed plate, and a rotating tube is installed on the fixed plate. This makes the overall size of this structure larger and more three-dimensional compared to the smaller diameter handles in the prior art, making it more convenient and less strenuous to hold. The telescopic rod is connected by a detachable buckle, which can be selectively installed to increase the irradiation detection distance. When inspecting the roof of large SUVs and MPVs, the inspection can be completed by walking around half a circle of the vehicle, reducing the labor intensity of frequently moving and climbing A-frame ladders and improving efficiency. The rotating tube is movably engaged with the bracket plate of the fixed plate through the action of a chuck support spring. The angle of the telescopic rod can be directly adjusted by manual rotation as needed, meeting usage requirements and possessing strong practicality, bringing great convenience to users.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-6 As shown, this utility model provides a technical solution: a paint inspection device for used car evaluation, including a striped reflector 1, a edging 2 around the striped reflector 1, a non-closed annular support rib 3 inserted inside the edging 2, the two ends of the support rib 3 being fixedly connected to the two sides of a fixed plate 4, and a left-right symmetrical bracket plate 401 provided on the fixed plate 4, the bracket plate 401 and the fixed plate 4 being an integral metal structure, having a high connection strength with the support rib 3;

[0027] A rotating tube 5 is provided between the two support plates 401. A chuck 6 is movably inserted into both sides of the inside of the rotating tube 5. A fixed shaft 7 for movably inserting the chuck 6 is fixed on the support plate 401. V-shaped rotating slots 8 are provided on the opposite surfaces of the support plate 401 and the chuck 6. The support plate 401 and the chuck 6 are interlocked with each other through the V-shaped rotating slots 8.

[0028] The middle surface of the rotating tube 5 is provided with a slot 501, and the rotating tube 5 is provided with a mounting slot 502 at the position corresponding to the slot 501. The mounting slot 502 and the rotating tube 5 are integrally injection molded structures, which facilitates production and assembly. The inner walls on both sides of the mounting slot 502 are provided with positioning slots 503 for engaging the buckle 9. The rotating tube 5 is movably engaged with the buckle 9 through the mounting slot 502. The end of the buckle 9 is fixed with a connecting seat 901. The buckle 9 and the connecting seat 901 are integrally injection molded structures, which facilitates production and assembly. The buckle 9 is fixed with a telescopic rod 10 through the connecting seat 901.

[0029] Limiting plates 11 are movably connected above and below the mounting slot 502. The upper and lower surfaces of the mounting slot 502 are both flat. The opposite surfaces of the two limiting plates 11 are slidably connected to the upper and lower surfaces of the mounting slot 502, respectively. The limiting plates 11 and the chuck 6 are integrally injection molded structures, which facilitates production and assembly. The opposite ends of the two limiting plates 11 are fixedly connected to the opposite surfaces of the two chucks 6, respectively. A support spring 12 is installed between the chuck 6 and the mounting slot 502.

[0030] Working principle:

[0031] A fixing plate 4 is connected to the support rib 3, and a rotating tube 5 is installed on the fixing plate 4. This makes the overall size of this structure larger and more three-dimensional compared to the smaller diameter handles in the prior art, making it more convenient and less strenuous to hold. By pressing the two sides of the buckle 9, the buckle 9 can be connected and separated from the mounting slot 502, realizing the disassembly and assembly of the telescopic rod 10 and the rotating tube 5. When inspecting the paint surface of the roof of large SUVs and MPVs, the telescopic rod 10 can be selectively installed, and the telescopic rod 10 can be manually extended and shortened to increase the illumination and detection distance of the striped reflector 1. At most, the entire roof can be inspected by circling half a circle around the vehicle. The chuck 6 is supported by the support spring 12, so that the chuck 6 can extend and retract within the rotating tube 5 under the action of external force. The limiting plate 11 prevents the chuck 6 from rotating relative to the rotating tube 5. Therefore, by manually bending the telescopic rod 10, the rotating tube 5 and the chuck 6 can be rotated to adjust the angle between the telescopic rod 10 and the striped reflector 1 to meet the needs of use and ensure strong practicality.
