Detailed Implementation

[0024] The present invention will now be described in further detail with reference to specific embodiments and the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0025] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein the same reference numerals denote the same parts unless otherwise specifically stated.

[0026] A ventilation duct inspection device includes a flat plate 1, several hole detection blocks 2, protrusion detection blocks 3, air inlet detection blocks 4, and air outlet detection blocks 5. The hole detection blocks 2 are arranged in contact with the upper surface of the flat plate 1. The protrusion detection blocks 3, air inlet detection blocks 4, and air outlet detection blocks 5 are respectively mounted on the upper surface of the flat plate 1 via a first column 6, a second column 7, and a third column 8. The air inlet detection block 4 is located on the left side of the flat plate 1 and has a first hollow portion 41. The shape and size of the first hollow portion 41 correspond to the ventilation duct. The air inlet 02 of the ventilation duct 01 is matched, and the air inlet detection block 4 is slidably mounted on the second column 7 via the first connecting rod 9, so that the air inlet 02 of the ventilation duct 01 can enter and move away from the first hollow part 41, so as to achieve the purpose of inspecting the size and deformation of the air inlet 02; the air outlet detection block 5 is located on the right side of the plate 1, and the air outlet detection block 5 is provided with a second hollow part 51. The shape and size of the second hollow part 51 match the air outlet 03 of the ventilation duct 01. The air outlet detection block 5 is slidably mounted on the third column 7 via the second connecting rod 10. On column 8, the air outlet 03 of ventilation duct 01 can enter and move away from the second hollow part 51, so as to achieve the purpose of inspecting the size and deformation of the air outlet 03; the hole position detection block 2 is arranged side by side with a spacing between the air inlet detection block 4 and the air outlet detection block 5. The front side of the hole position detection block 2 is a slope, specifically, the lower part of the slope is inclined outward. The slope is provided with a first protrusion 21, which corresponds to the first through hole 04 on the ventilation duct 01, and is used to inspect the position and size of the first through hole 04 on the ventilation duct 01. The first through hole 04 is located at the lower part of the ventilation duct 01; the protrusion detection block 3 is located behind the hole detection block 2 and near the air inlet detection block 4. The protrusion detection block 3 is provided with a second through hole 31. The size of the second through hole 31 matches the second protrusion (not shown in the figure) on the ventilation duct 01. The protrusion detection block 3 is rotatably mounted on the first column 6. When the protrusion detection block 3 is rotated above the ventilation duct 01, the second through hole 31 matches the second protrusion to detect whether the position and size of the second protrusion on the ventilation duct 01 are correct.

[0027] The aforementioned inspection device can accurately inspect the dimensions and positions of important parts of the ventilation duct 01, namely the dimensions and positions of the air inlet 02, air outlet 03, first through hole 04, and second protrusion. If the air inlet 02 and air outlet 03 can smoothly enter and move away from the first hollow part 41 and the second hollow part 51, respectively, and the component containing the first through hole 04 on the ventilation duct 01 can be smoothly installed on the hole position detection block 2, so that the first through hole 04 matches the first protrusion 21, and the second through hole 31 on the protrusion detection block 3 can smoothly match the second through hole on the ventilation duct 01, then it indicates that the position and size of the ventilation duct 01 are correct, the overall deformation is within the allowable range, and it is a qualified product that can be installed on a car for ventilation. Otherwise, the ventilation duct 01 is considered unqualified and cannot be installed on a car, thus avoiding system failure and other safety issues caused by deviations in the dimensions and positions of the installation holes of the ventilation duct 01 and other important components.

[0028] In some examples of this embodiment, a first limiting block 11 is also provided on the rear side of the hole detection block 2 and near the air outlet detection block 5. The first limiting block 11 is slidably disposed on the fourth column 12, so that the first limiting block 11 can abut against or move away from the ventilation duct 01. During the detection, it can provide a force to the ventilation duct 01 to prevent the ventilation duct 01 from tipping over, facilitate the connection between the air outlet detection block 5 and the air outlet 03, improve the inspection speed, and can also detect the deformation of the ventilation duct 01 to a certain extent. It is understood that if the ventilation duct 01 is deformed too much, the air outlet 03 will have great difficulty entering and moving away from the second hollow part 51.

[0029] In other examples of this embodiment, the second column 7 and the third column 8 are respectively provided with a third through hole and a fourth through hole. The first connecting rod 9 and the second connecting rod 10 are respectively slidably disposed in the third through hole and the fourth through hole. A plurality of fifth through holes 91 can also be arranged side by side on the first connecting rod 9 and the second connecting rod 10 along their sliding direction, and a stop 13 matching the fifth through hole 91 is provided. Specifically, a plastic spring 14 can be used to connect with the stop 13, and the other end of the plastic spring 14 can be fixed near the second column 7 and the third column 8 for convenient use during inspection and to improve inspection efficiency. The matching of the stop 13 with the fifth through hole 91 at different positions indicates that the first connecting rod 9 and the second connecting rod 10 extend at different distances, so as to detect ventilation ducts 01 of different sizes in the same series and improve the versatility of the inspection device.

[0030] In some other examples of this embodiment, the hole position detection block 2 includes a horizontal block 22 and a vertical block 23. The horizontal block 22 and the vertical block 23 are combined to form an approximately "L" shape. Several bolts are provided on the horizontal block 22 to fix the hole position detection block 2 to the plate 1. The hole position detection block 2 is fixed from the front of the plate 1, which facilitates disassembly and assembly. Specifically, the horizontal block 22 and the vertical block 23 can be integrally formed to reduce the use of bolts and improve the accuracy and installation efficiency of the inspection device.

[0031] In other examples of this embodiment, the flat plate is provided with several handles 15 to facilitate moving the entire device during operation, such as... Figure 1 As shown in the example, one is set on the front and one on each of the left and right sides of the plate 1, so that the operator can lift the entire device to the place where it needs to be inspected.

[0032] The inspection process of the above-mentioned inspection device is as follows: The first through hole 04 of the ventilation duct 01 is fully inserted into the first protrusion 21 on the hole position detection block 2; the air inlet detection block 4 is pushed so that the first hollow part 41 covers the air inlet 02. After reaching the designated position, the stop block 13 is inserted into the fifth through hole 91; the protrusion detection block 3 is rotated so that the second through hole 31 matches the second protrusion; the first limiting block 11 is pushed so that it abuts against the ventilation duct 01; the air outlet detection block 5 is pushed so that the second hollow part 51 covers the air outlet 03. After reaching the designated position, the stop block 13 is inserted into the fifth through hole 91. Then the above actions are repeated in reverse. If all actions can be easily completed, it indicates that the position and size of each component of the ventilation duct 01 are correct, and the deformation is within the allowable range. The ventilation duct 01 is a qualified product. Otherwise, it is a defective product and cannot be used for installation in the next process flow.

[0033] Those skilled in the art will recognize that numerous variations are possible with respect to the above description, and the embodiments and figures are merely for describing one or more specific implementations.

[0034] Although exemplary embodiments of the present invention have been described and illustrated, those skilled in the art will understand that various changes and substitutions can be made thereto without departing from the spirit of the present invention. Furthermore, many modifications can be made to adapt specific situations to the doctrine of the present invention without departing from the central concept of the present invention described herein.
