Therefore, it should not be understood as limiting the scope of protection of this application.

[0034] The following is combined with Figures 1 to 4 This application is described in further detail.

[0035] The present application provides a portable product air tightness detection device, comprising: a portable mobile chassis 1, on which a mobile gas cylinder 2 and a detection box 3 are movably mounted.

[0036] Specifically, such as Figure 1As shown, the portable mobile chassis 1 includes a positioning mechanism 4 and two auxiliary support plates 5. The positioning mechanism 4 is provided with a mobile gas cylinder positioning structure for installing the mobile gas cylinder 2 and a detection box positioning structure for installing the detection box 3. The two auxiliary support plates 5 are symmetrically fixed on both sides of the positioning mechanism 4, and a sliding wheel 6 is installed at the bottom of each auxiliary support plate 5.

[0037] The portable product air tightness detection device of the present application drives the mobile gas cylinder 2 and the detection box 3 to the detection position through the portable mobile chassis 1 before performing an air tightness test on the aircraft. After the mobile gas cylinder 2 is connected to the detection box 3, the aircraft is subjected to an air tightness test.

[0038] In a preferred embodiment of the present application, the auxiliary support plate 5 drives the positioning mechanism 4 to move via the sliding wheel 6. The sliding wheel 6 at the bottom of the auxiliary support plate 5 is provided with a stop lock, which can realize the locking function and facilitate the installation of the mobile gas cylinder 2.

[0039] In a preferred embodiment of the present application, a pallet handle 8 is fixedly mounted on any one of the auxiliary pallets 5. The operator can push the pallet handle 8 to move the entire portable mobile chassis 1 and the mobile gas cylinder 2 and the detection box 3 to perform air tightness testing on the aircraft.

[0040] The portable product air tightness detection device of the present application, the positioning mechanism 4 includes: a positioning base plate 41, an inclined bottom support block 43, and an inclined support plate 44.

[0041] A box positioning slot 42 is fixedly mounted in the center of the positioning base plate 41. This slot 42 is used to removably mount the detection box 3. The slot walls of the box positioning slot 42 should be of a certain height to allow the detection box 3 to be stably mounted therein. Alternatively, one of the slot walls at an appropriate position can be provided with a removable structure. This wall can be removed during installation of the detection box 3 to facilitate assembly of the detection box 3.

[0042] The cross section of the inclined bottom support block 43 is a right triangle. The inclined bottom support blocks 43 include two of them, which are symmetrically fixed on both sides of the box positioning groove 42. One side wall of the inclined bottom support block 43 can be set adjacent to the groove wall of the box positioning groove 42, or one side wall of the inclined bottom support block 43 can be directly used as the groove wall of the box positioning groove 42. The inclined support plates 44 include two of them, which are symmetrically fixed on both sides of the positioning base plate 41, and the inclined support plates 44 and the auxiliary support plates 5 on the corresponding sides are fixedly connected by auxiliary force blocks 7. The auxiliary force blocks 7 can distribute part of the gravity of the mobile gas cylinder 2 to the auxiliary support plates 5, thereby reducing the load on the positioning base plate 41. The inclined support plates 44 and the inclined bottom support blocks 43 on the corresponding sides are perpendicular to each other, and a positioning groove 45 is formed at the connection between the inclined support plates 44 and the inclined bottom support blocks 43. The positioning groove 45 is used for the movable installation of the mobile gas cylinder 2.

[0043] In a preferred embodiment of the present application, Figure 2 As shown, a plurality of fixing belts 9 for binding the mobile gas cylinder 2 are fixedly installed on one side of the inclined support plate 44 close to the box positioning groove 42. The fixing belts 9 can fix the position of the mobile gas cylinder 2 to prevent the mobile gas cylinder 2 from rolling.

[0044] The portable product air tightness testing device of the present application forms a testing box positioning structure through the box positioning groove 42 on the positioning base plate 41 of the positioning mechanism 4, thereby realizing the assembly of the testing box 3; and forms a mobile gas cylinder positioning structure through the inclined bottom support block 43, the inclined support plate 44 and the fixing belt 9 on the positioning base plate 41, thereby realizing the assembly of the mobile gas cylinder 2. The positioning mechanism 4 fixes the testing box 3 and the mobile gas cylinder 2 through the positioning base plate 41, fixes the position of the testing box 3 through the box positioning groove 42, and then vertically cooperates with the two inclined bottom support blocks 43 and the two inclined support plates 44 through the two inclined bottom support blocks 43, so that the mobile gas cylinder 2 can be tilted and supported on the positioning base plate 41, which can maintain stability and facilitate the transfer and transportation of the mobile gas cylinder 2. The mobile gas cylinder 2 enters the inclined support plate 44 and the inclined bottom support block 43 from the position of the positioning groove 45.

[0045] In a preferred embodiment of the present application, Figure 3 、 4As shown, the positioning base plate 41 is provided with a locking hole 10 near the positioning groove 45; the positioning mechanism 4 also includes: a power-assisting groove plate 46, which includes two mutually perpendicular power-assisting supporting plates 461, and the connection between the two power-assisting supporting plates 461 forms an auxiliary groove 462. The power-assisting groove plate 46 is provided with a locking member 463 near the auxiliary groove 462, and the locking member 463 can be engaged with the locking hole 10. The power-assisting groove plate 46 overlaps with the ground through its bottom, so that the mobile gas cylinder 2 can roll at the auxiliary groove 462 and roll onto the positioning groove 45, and then be supported by the oblique supporting plate 44 and the oblique bottom supporting block 43. The locking cooperation between the locking member 463 and the locking hole 10 can facilitate the storage and installation of the power-assisting groove plate 46. Advantageously, in this embodiment, the auxiliary groove 462 coincides with the axis of the positioning groove 45 , so that the mobile gas cylinder 2 can easily transition directly to the interior of the positioning groove 45 through the auxiliary groove 462 , and is supported by the inclined support plate 44 and the inclined bottom support block 43 .

[0046] The portable product air tightness detection device of the present application, through the active docking of the power-assisting groove plate 46 and the positioning groove 45, can rotate the mobile gas cylinder 2 from the ground to the inclined support plate 44 and the inclined bottom support block 43 for support through the power-assisting groove plate 46, thereby facilitating the transfer and transportation of the mobile gas cylinder 2; at the same time, multiple mobile gas cylinders 2 can be connected to the detection box 3, thereby facilitating the efficient and rapid completion of the rapid inspection of the air tightness of the aircraft.

[0047] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
