Then the locking motor 220 drives the rotating frame 212 to rotate counterclockwise, and the driving arm 214 is now in contact with the locking arm 217 and drives the sealing cover 202 to rotate counterclockwise. When the locking block 208 moves to the position of the inner locking cavity 205, the locking block 208 automatically pops out and inserts into the inner locking cavity 205 under the action of the reset spring 210 to complete the double locking. The storage mechanism 2 is installed in the installation cavity 102, and then the storage tube 201 is rotated clockwise to insert the locking boss 203 into the locking hoop 104 to complete the preliminary locking. Finally, the locking ring 105 is installed on the installation cavity 102 and the insert block 106 is located between the adjacent locking hoops 104, so that the locking boss 203 is locked again. After the device is installed on the landing gear 1, the device is driven to the crack where glue injection is required by the drone. Finally, by controlling the on-off combination and rotation speed coordination of the first motor 313 and the second motor 315, the complex movement of the glue injection nozzle 320 can be achieved.

[0023] See attached Figure 2 and attached Figure 4 A plurality of locking bosses 203 are fixedly provided on the outer wall of the storage cylinder 201 , a locking convex ring 103 is provided at the bottom of the installation cavity 102 , and a plurality of locking hoops 104 cooperating with the locking bosses 203 are spaced apart at the top of the locking convex ring 103 .

[0024] In this embodiment, during installation, the storage barrel 201 is first installed in the installation cavity 102, and the locking boss 203 is located between adjacent locking hoops 104. Then the storage barrel 201 is rotated clockwise to insert the locking boss 203 into the locking hoop 104 to complete the preliminary locking.

[0025] See attached Figure 2 -Attached Figure 4 A locking ring 105 is also installed on the top of the installation cavity 102 to limit the locking boss 203. A plurality of plug blocks 106 are arranged at the bottom of the locking ring 105, and a plurality of screws 107 are installed on the top of the locking ring 105.

[0026] In this embodiment: after the locking boss 203 is inserted into the locking hoop 104, the locking ring 105 is installed on the installation cavity 102 and the insert block 106 is located between adjacent locking hoops 104, so that the locking boss 203 is locked again, and finally the locking ring 105 is fixed by multiple sets of screws 107.

[0027] See attached Figure 4 -Attached Figure 7 The outer wall of the locking block 208 is connected to the outer wall of the sealed cover 202 through multiple sets of return springs 210, and multiple sets of driving arms 214 are fixedly arranged on the rotating frame 212, and the inner side of the driving arms 214 is installed with magnetic suction parts 215; multiple sets of unlocking arms 216 and locking arms 217 located on both sides of the outer locking cavity 207 are installed on the outer wall of the sealed cover 202. When the rotating frame 212 rotates, the driving arms 214 cooperate with the unlocking arms 216 and locking arms 217 on both sides to realize the locking and unlocking of the locking block 208.

[0028] In this embodiment, during installation, the sealing cover 202 is first installed on the top of the storage cylinder 201, and the sealing ring 204 is inserted into the annular groove 206. At this time, the driving arm 214 is located between the unlocking arm 216 and the locking arm 217. When the locking motor 220 drives the rotating frame 212 to rotate counterclockwise, the driving arm 214 is in contact with the locking arm 217 and drives the sealing cover 202 to rotate counterclockwise. When the locking block 208 moves to the position of the inner locking cavity 205, the locking block 208 automatically pops out and is inserted into the inner locking cavity 205 under the action of the return spring 210 to complete the double locking. When the locking motor 220 drives the rotating frame 212 to rotate clockwise, the driving arm 214 first disengages from the locking arm 217. When the rotating frame 212 moves to a position in which it is in contact with the unlocking arm 216, the locking block 208 is automatically unlocked and pulled out from the inner locking cavity 205 under the action of the magnetic suction member 215. The rotating frame 212 continues to rotate clockwise to completely disengage the locking block 208 from the inner locking cavity 205.

[0029] See attached Figure 5 -Attached Figure 6 A gear ring 218 is installed at the bottom of the rotating frame 212, a convex plate 219 is fixedly provided on the outer wall of the storage cylinder 201, a locking motor 220 is installed on the top of the convex plate 219, and a locking gear 221 meshing with the gear ring 218 is installed at the output end of the locking motor 220.

[0030] In this embodiment, in order to automatically drive the rotating frame 212 to rotate, thereby further locking and unlocking the storage cylinder 201 and the sealing cover 202, a locking motor 220 structure is designed.

[0031] See attached Figure 6 A T-shaped cavity 211 is provided on the outer wall of the storage cylinder 201 , and a top rail 213 matching with the rotating frame 212 is provided on the top.

[0032] In this embodiment, in order to install the rotating frame 212 and further improve its stability during rotation, a T-shaped cavity 211 and a top rail 213 structure that cooperate with each other are designed.

[0033] See attached Figure 6 and attached Figure 8 -Attached Fig. 9 A pump 223 is installed on the inner wall of the bottom of the storage cylinder 201, and a glue injection cavity 224 connected to the pump 223 is provided inside the storage cylinder 201; a hose 321 is movably installed between the glue injection cavity 224 and the glue injection nozzle 320, and a hole groove 302 for the hose 321 to pass through is also provided in the middle of the mounting frame 301; a rotating convex ring 322 is fixedly provided at the bottom of the swing frame 318, and a limiting hoop 323 cooperating with it is provided at the end of the hose 321.

[0034] In this embodiment, driven by the pump 223, the injection material in the storage barrel 201 enters the hose 321 through the injection cavity 224. During the injection operation, since the swing frame 318 and the injection nozzle 320 continuously rotate and swing, in order to ensure that the hose 321 and the injection nozzle 320 are movably connected, a rotating convex ring 322 and a limiting hoop 323 structure that cooperate with each other are designed.

[0035] See attached Figure 8 -Attached Fig.11A swing gear 309 is installed on the outer wall of the inner rotating cylinder 303, and a linkage member 310 is installed on the outer wall of the outer rotating cylinder 306. The linkage member 310 includes a swing gear 2 311 and a first bevel gear 312 fixedly arranged on the top thereof, and a second bevel gear 319 meshing with the first bevel gear 312 is fixedly installed on the inner wall of the swing frame 318; a symmetrical first motor 313 and a second motor 315 are installed at the bottom of the mounting frame 301, and a driving gear 1 314 meshing with the swing gear 1 309 is installed at the output end of the first motor 313, and a driving gear 2 316 meshing with the swing gear 2 311 is installed at the output end of the second motor 315.

[0036] In this embodiment: when the first motor 313 drives the swing gear 1 309 to rotate and the second motor 315 is not started, the swing frame 318 drives the glue injection nozzle 320 to swing rapidly. When the second motor 315 drives the swing gear 2 311 to rotate and the first motor 313 is not started, the swing frame 318 drives the glue injection nozzle 320 to swing rapidly under the cooperation of the first bevel gear 312 and the second bevel gear 319. When the first motor 313 and the second motor 315 are started synchronously and have the same rotation speed, the swing frame 318 drives the glue injection nozzle 320 to rotate rapidly. When the first motor 313 and the second motor 315 are started synchronously but have different rotation speeds, complex movements of the glue injection nozzle 320 can be achieved, including but not limited to swinging and rotating at the same time, thereby meeting the glue injection requirements of various complex cracks.

[0037] See attached Fig. 9 -Attached Fig.10 A T-shaped slot 304 is provided on the top of the mounting frame 301, and a T-shaped rail 305 matching therewith is fixedly provided on the bottom of the inner rotating cylinder 303; a limiting convex ring 307 is provided on the outer wall of the inner rotating cylinder 303, and a limiting groove 308 matching therewith is provided on the inner wall of the outer rotating cylinder 306.

[0038] In this embodiment, in order to ensure that the inner rotating cylinder 303 can rotate freely relative to the top of the mounting frame 301, a T-slot 304 and a T-rail 305 structure that cooperate with each other are designed. In order to ensure that the outer rotating cylinder 306 is movably mounted on the outer wall of the inner rotating cylinder 303, a limiting convex ring 307 and a limiting groove 308 structure that cooperate with each other are designed.

[0039] See attached Figure 4 -Attached Figure 6 The unlocking arm 216 is flush with the left side of the outer locking cavity 207 , a circular arc portion 209 is provided at the bottom of the locking block 208 , and a control panel 222 is also provided on the outer wall of the storage cylinder 201 .

[0040] In this embodiment: when unlocking, after the magnetic member 215 pulls the locking block 208 out of the inner locking cavity 205, in order to synchronously drive the sealed cover 202 to rotate through the driving arm 214 and prevent the locking block 208 from automatically retracting into the inner locking cavity 205 again, the unlocking arm 216 is flush with the left side of the outer locking cavity 207, thereby ensuring that the magnetic member 215 is always completely magnetically matched with the locking block 208. When the sealed cover 202 is installed on the top of the storage cylinder 201, the sealed ring 204 will squeeze the arc portion 209, and the locking block 208 will automatically pop out along the outer locking cavity 207.

[0041] Working principle of the present invention: When the device is used, the injection raw material is first added into the storage cylinder 201. Then the rotating frame 212 is driven to rotate counterclockwise by the locking motor 220, and the driving arm 214 is now in contact with the locking arm 217 and drives the sealing cover 202 to rotate counterclockwise. When the locking block 208 moves to the position of the inner locking cavity 205, the locking block 208 automatically pops out and is inserted into the inner locking cavity 205 under the action of the reset spring 210 to complete the double locking. The storage mechanism 2 is installed in the installation cavity 102, and then the storage cylinder 201 is rotated clockwise so that the locking boss 203 is inserted into the locking hoop 104 to complete the preliminary locking. Finally, the locking ring 105 is installed on the installation cavity 102 and the insert block 106 is located between adjacent locking hoops 104, so that the locking boss 203 is locked again. After the device is installed on the landing gear 1, the device is driven to the crack where the glue needs to be injected by the drone. Finally, by controlling the on / off combination and rotation speed coordination of the first motor 313 and the second motor 315 , the complex movement of the glue injection nozzle 320 can be achieved.
