Technical Field

[0001] The utility model relates to the technical field of aerial cameras, in particular to a large-scale aerial camera platform ball cover disassembly tool. Background Art

[0002] With the continuous development of aerial cameras, aerial cameras are applied in various fields. The working environment of their components is relatively harsh and is affected by vibration, impact and other environmental factors. Therefore, a ball cover for protecting the aerial camera needs to be installed on the outside of the aerial camera.

[0003] The existing ball cover is cast aluminum, and is very heavy to match the size of the aerial camera. In addition, its surface is very smooth and there is nowhere to apply force. If the ball cover needs to be lifted, the handle needs to be installed at the countersunk hole of the ball cover through multiple screws. After multiple installation and removal of the handle and the ball cover in this way, many thread stripping will be left in the countersunk hole of the ball cover, which will not only damage the ball cover, but also leave safety hazards for the next handle assembly and ball cover lifting due to the occurrence of thread stripping. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a large-scale aerial camera platform ball cover disassembly tool, which can be quickly installed on the surface of the ball cover and lift the ball cover, and after lifting the ball cover, it can also be quickly disassembled from the surface of the ball cover without damaging the ball cover.

[0006] Furthermore, the disassembly tool includes a connecting piece and a disassembly screw; wherein, the end of the tension sleeve away from the slit is screwed into the connecting piece from the bottom end of the connecting piece, and the disassembly screw is screwed into the interior of the connecting piece from the top end of the connecting piece, so that the tension sleeve and the disassembly screw are connected through the connecting piece, and the fixed end is connected to the disassembly screw inside the connecting piece.

[0007] Furthermore, a groove having the same diameter as the disassembly screw is formed at the top of the fixed end, so that the disassembly screw can extend into the groove.

[0008] Furthermore, the head of the disassembly screw adopts a spherical structure, and the surface of the disassembly screw is provided with threads extending from the head of the disassembly screw to the tail of the disassembly screw.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and do not constitute a limitation of the utility model.

[0019] The large-scale aerial camera platform ball cover disassembly tool provided by the utility model can be quickly installed on the surface of the ball cover and lifted by the cooperation of the tensioning core shaft and the tensioning sleeve. After the ball cover is lifted, it can also be quickly removed from the surface of the ball cover without damaging the ball cover, thereby improving the overall practicality of the tool and the safety during the lifting process.

[0020] Figure 1 and Figure 2 The overall and partial structures of the ball cover disassembly tool for a large-scale aerial camera platform provided according to an embodiment of the utility model are respectively shown.

[0021] like Figure 1 and Figure 2 As shown, the large-scale aerial camera platform ball cover disassembly tool provided by the embodiment of the utility model comprises a handle 1 and two tensioning installation mechanisms for installing the handle in the countersunk hole 11 of the external ball cover.

[0022] Each tensioning installation mechanism includes a tensioning mandrel 2, a tensioning sleeve 3, a locking nut 4 and a disassembly tool. The tensioning mandrel 2 is inserted into the tensioning sleeve 3, and the locking nut 4 clamps the tensioning sleeve 3 and the handle 1 on the tensioning mandrel 2. The disassembly tool is fixed on the tensioning mandrel 2.

[0023] Figure 3 The structure of the tensioning installation mechanism provided according to the embodiment of the utility model is shown. Figure 4 and Figure 5 The structures of the tensioning sleeve and the tensioning mandrel provided according to the embodiments of the utility model are respectively shown.

[0024] like Figure 2 to Figure 5 As shown, the tensioning mandrel 2 includes a tensioning end 5, a tensioning shaft 6 and a fixed end 7 of an integrated structure. The diameter of the end of the tensioning end 5 is consistent with the diameter of the counterbore 11 of the external ball cover, and the diameter of the tensioning end 5 gradually decreases along the axial direction of the tensioning end 5. The disassembly tool is threadedly connected to the fixed end 7 and is used to pull the tensioning mandrel 2 out of the counterbore 11.

[0025] One end of the tension sleeve 3 is provided with at least three slits 8 along the axial direction of the tension sleeve 3, the length of the slits 8 is greater than the length of the tension end 5, and the slits 8 are close to the tension end 5. The other end of the tension sleeve 3 is provided with an external thread, and the locking nut 4 cooperates with the external thread to fasten the tension sleeve 3 to the tension shaft 7.

[0026] like Figure 1As shown, the disassembly tool includes a connecting piece 9 and a disassembly screw 10. Among them, the end of the tension sleeve 3 away from the slit 8 is screwed into the connecting piece 9 from the bottom end of the connecting piece 9, and the disassembly screw 10 is screwed into the inside of the connecting piece 9 from the top end of the connecting piece 9, so that the tension sleeve 3 and the disassembly screw 10 are connected through the connecting piece 9, and the fixed end 7 and the disassembly screw 10 are connected inside the connecting piece 9.

[0027] Preferably, in this specific embodiment, countersunk holes 11 are provided on both sides of the ball cover according to actual needs, the tensioning installation mechanism is made of 2Cr13 (stainless steel) material, the handle 1 is made of 2A12 (aluminum alloy) material, and stripes for increasing friction are arranged on the surface of the handle 1. The number of slits 8 is 3, so that the side wall of one end of the tension sleeve 3 is evenly divided into 3 parts. The locking nut 4 uses an M8 expansion nut, and the load-bearing capacity of an M8 expansion nut is about 50 to 150 kilograms, which can enable the handle 1 to lift the ball cover stably and safely.

[0028] Figure 6 The structure of the screw removal provided according to the embodiment of the utility model is shown.

[0029] like Figure 6 As shown, the disassembly screw 10 adopts an M4 bolt, and the thread on the surface of the disassembly screw 10 extends from the head of the disassembly screw 10 to the tail of the disassembly screw 10. The head of the disassembly screw 10 adopts a spherical structure to further enhance the force during disassembly. When in use, the disassembly screw 10 is screwed into the interior of the connecting member 9 and the fixed end 7, so that the spherical head of the disassembly screw 10 is against the tensioning mandrel 2.

[0030] The process of installing the handle 1 in the countersunk holes 11 on both sides of the ball cover is as follows:

[0031] Insert the tightening end 5 of the tightening mandrel 2 into the countersunk hole 11, and then insert one end of the slit 8 of the tightening sleeve 3 into the countersunk hole 11 along the tightening mandrel 2. The two ends of the handle 1 are respectively mounted on the tightening sleeve 3, and then the locking nut 4 is screwed on the external thread of the tightening sleeve 3. At this time, the locking nut 4 provides downward pressure along the tightening mandrel 2 to the handle 1 and the tightening sleeve 3. As the locking nut 4 presses the handle 1, the tightening sleeve 3 changes torque and expands to the entire countersunk hole 11. At this time, the handle 1 is also fixed on the tightening sleeve 3 by the tightening of the locking nut 4, and the installation of the handle 1 on the ball cover is completed. When the handle 1 is lifted, the handle 1 will be subjected to an upward force, and the tightening sleeve 3 will generate a reaction force on the inner wall of the countersunk hole 11, increasing the contact area between the countersunk hole 11 and the tightening sleeve 3, making the connection more reliable and protecting the ball cover from being damaged to the greatest extent.

[0032] After the ball cover is lifted, the process of removing the handle 1 from the countersunk holes 11 on both sides of the ball cover is as follows:

[0033] Remove the lock nut 4 and the handle 1 from the tension sleeve 3, and connect the connector 9 to the tension sleeve 3 through threads. Screw the disassembly screw 10 into the connector 9 and abut against the fixed end 7. Due to the conical structure of the tension sleeve 3 and the slit 8 on the surface of the tension sleeve 3, the tension sleeve 3 has a tendency to move upward along the tensioning mandrel 2 while shrinking. At this time, continue to rotate the connector 9, and the internal thread of the connector 9 pulls the external thread of the tension sleeve 3, so that the tension sleeve 3 moves upward. When the tension sleeve 3 moves to a certain length, the tension sleeve 3 can be easily pulled out, and finally the tensioning mandrel 2 is taken out.

[0034] The above specific implementations do not constitute a limitation on the protection scope of the present utility model. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
