Description

Technical Field

[0001] This utility model relates to the field of aerial camera transition plate technology, and in particular to a transition connection device for airborne aerial cameras. Background Technology

[0002] Aerial cameras are instruments mounted on airplanes or other aircraft to photograph the ground from the air. When mounting an aerial camera on an aircraft, the PAV (Portable Aerial Vehicle) mount of the aerial camera is usually stably installed on the aircraft's camera hatch. However, the pre-drilled holes in each aircraft hatch cannot be directly used to install the PAV mount, so a transition plate is required. The transition plate is first installed on the aircraft's camera hatch, and then the PAV mount is installed onto the transition plate. The general structure of the transition plate in the prior art includes a horizontally positioned transition plate with a lens insertion hole at its center and multiple countersunk through holes for connecting the camera hatch and the PAV mount. Since the transition plate is a metal plate about 1.5m long and wide, it is quite heavy. During installation, the position of the transition plate needs to be constantly moved and transported to align the countersunk through holes on the transition plate with the pre-drilled mounting holes in the camera hatch. The installation is time-consuming and labor-intensive, and urgently needs improvement. Utility Model Content

[0003] The purpose of this invention is to provide a transition connection device for airborne aerial cameras to solve the technical problem that the transition plate is inconvenient to move during the installation process in the prior art.

[0004] The present invention relates to a transition connection device for an airborne aerial camera, comprising a horizontally arranged transition plate, a lens insertion hole at the center of the transition plate, a plurality of first countersunk through holes and second countersunk through holes, the first countersunk through holes and the second countersunk through holes being opened in opposite directions, a plurality of threaded through holes being provided on the transition plate, and a telescopic ball assembly being provided in the threaded through holes for assisting in moving the transition plate.

[0005] Furthermore, the telescopic ball assembly includes an adjusting post, which is screwed into the threaded through hole. A mounting groove is provided at the bottom end of the adjusting post. A compression spring and a ball are sequentially installed in the mounting groove. A locking ring is installed at the opening of the mounting groove. The inner diameter of the locking ring is smaller than the diameter of the ball. The ball extends outside the threaded through hole.

[0006] Furthermore, two positioning pins are installed on the locking ring, and a positioning groove matching the positioning pin is opened on the end face of the adjusting pin, and the positioning pin is fixedly inserted into the positioning groove.

[0007] Furthermore, a third countersunk through hole is provided on the locking ring, and a screw hole matching the third countersunk through hole is provided at the bottom of the positioning groove. A bolt is inserted into the third countersunk through hole and screwed into the screw hole.

[0008] Furthermore, a hexagonal groove is provided at the other end of the adjusting column.

[0009] Furthermore, the transition plate is made of 7075 aerospace aluminum alloy.

[0010] The beneficial effects of this utility model are as follows: Based on the traditional transition plate, this utility model designs a telescopic rolling ball assembly device, which facilitates the movement and adjustment of the transition plate during installation, making the installation of the transition plate time-saving, labor-saving, quick and convenient, and worthy of promotion and use.

[0016] In the figure, there are: transition plate 1, lens socket 2, first countersunk through hole 3, second countersunk through hole 4, threaded through hole 5, adjusting post 6, mounting groove 7, compression spring 8, ball bearing 9, locking ring 10, positioning post 11, screw hole 12, third countersunk through hole 13, nut 14, and hexagonal groove 15. Detailed Implementation

[0017] like Figure 1 and Figure 2 As shown, a transition connection device for an airborne aerial camera includes a horizontally arranged transition plate 1. A lens insertion hole 2 is provided at the center of the transition plate 1. Several first countersunk through holes 3 and second countersunk through holes 4 are provided on the transition plate 1. The first countersunk through holes 3 and second countersunk through holes 4 are opened in opposite directions. Several threaded through holes 5 are also provided on the transition plate 1. Telescopic ball assemblies are provided in the threaded through holes 5. The telescopic ball assemblies are used to assist in moving the transition plate 1.

[0018] like Figures 3 to 5As shown, the telescopic ball assembly includes an adjusting post 6, which is screwed into the threaded through hole 5. A mounting groove 7 is provided at the bottom end of the adjusting post 6. A compression spring 8 and a ball 9 are sequentially installed in the mounting groove 7. A locking ring 10 is installed at the opening of the mounting groove 7. The inner diameter of the locking ring 10 is smaller than the diameter of the ball 9, and the ball 9 extends beyond the threaded through hole 5. Two positioning posts 11 are installed on the locking ring 10. A positioning groove matching the positioning post 11 is provided on the end face of the adjusting post 6, and the positioning post 11 is fixedly inserted into the positioning groove. A third countersunk through hole 13 is provided on the locking ring 10. A screw hole 12 matching the third countersunk through hole 13 is provided at the bottom of the positioning groove. A bolt is inserted into the third countersunk through hole 13 and screwed into the screw hole 12. A hexagonal groove 15 is provided at the other end of the adjusting post 6. The transition plate 1 is made of 7075 aviation aluminum alloy.

[0019] When adjusting and installing transition plate 1, such as Figures 1 to 5 As shown, the ball 9 on the telescopic ball assembly contacts the camera hatch plate. Due to the rolling performance of the ball 9, the transition plate 1 can be moved freely, so that the first countersunk through hole 3 is aligned with the reserved hole of the camera hatch. Bolts are screwed into the first countersunk through hole 3 and the reserved hole (at this time, the ball 9 is retracted under force) to install the transition plate 1 on the camera hatch. Then, the aerial camera PAV mount is installed at the position of the second countersunk through hole 4.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
