DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-4The utility model provides an embodiment: a recorder fixing device for unmanned aerial vehicle surveying and mapping, including a connecting block 1, an auxiliary block 3 is slidably connected to the lower part of the connecting block 1, a knob 19 is rotatably connected to the left side of the rear of the auxiliary block 3, and a bevel gear 1 20 is fixedly connected to the upper end of the knob 19. A two-way screw 4 is rotatably connected to the left side of the auxiliary block 3, and a bevel gear 2 21 is fixedly connected to the rear end of the two-way screw 4. Two sliders 5 are slidably connected to the front and rear sides of the auxiliary block 3, and the bottoms of the two sliders 5 are fixedly connected to fixed blocks 7, and the two right sliders 5 are slidably connected to the inside of the slide rods 6, a mounting plate 8 is provided in the middle of the auxiliary block 3, and the bottom of the mounting plate 8 is fixedly connected to the recorder body 2, and a mitigation component is provided inside the connecting block 1.

[0031] Specifically, first fix the connecting block 1 to the lower part of the drone, then turn the knob 19 to drive the bevel gear 1 20 to rotate, and then drive the bevel gear 2 21 meshing with it to rotate, and drive the bidirectional screw 4 to rotate. Since the bidirectional screw 4 is threadedly connected to the two sliders 5 on the left, and the two sliders 5 on the right slide on the outer periphery of the slide bar 6, the two fixed blocks 7 are driven to move to the front and rear sides of the auxiliary block 3. Then the staff places the recorder body 2 on the middle inner wall of the auxiliary block 3 through the mounting plate 8, and turns the knob 19 at the same time, thereby driving the two fixed blocks 7 to clamp the bottom of the mounting plate 8, and clamp the recorder body 2 through the anti-skid plate on the side close to the two fixed blocks 7, and then fix the recorder body 2 to facilitate the staff to install it.

[0032] The two left sliders 5 are both threadedly connected to the outer periphery of the bidirectional screw 4, and the front and rear ends of the slider 6 are fixedly connected to the right side of the auxiliary block 3.

[0033] Specifically, the bevel gear 1 20 is driven to rotate by rotating the knob 19, and then the bevel gear 2 21 meshing with it is driven to rotate, and the slider 5 is driven to move by the bidirectional screw 4, and the two fixed blocks 7 are more stable during the movement by the setting of the slide rod 6.

[0034] The two fixed blocks 7 are slidably connected to the bottom of the auxiliary block 3, the mounting plate 8 is arranged on the top of the two fixed blocks 7, and the two fixed blocks 7 are fixedly connected to the side close to each other with an anti-slip plate.

[0035] Specifically, it is convenient to drive the fixing block 7 to clamp the mounting plate 8, thereby preventing the recorder body 2 from sliding through the anti-slip plate.

[0036] Bevel gear 1 20 is meshed with bevel gear 2 21

[0037] Specifically, by rotating the knob 19 , the bevel gear 1 20 is driven to rotate, and then the bevel gear 2 21 is driven to rotate, so as to facilitate the movement of the two fixed blocks 7 .

[0038] The deceleration component includes a fixed rod 12, and the two fixed rods 12 are respectively fixedly connected to the front and rear sides of the inner wall of the connecting block 1, the middle periphery of the fixed rod 12 is fixedly connected to the support block 10, and the left and right peripheries of the fixed rod 12 are slidably connected to the moving blocks 9, the two moving blocks 9 are fixedly connected to the side away from the support block 10 with a spring b13, and the two moving blocks 9 are fixedly connected to the side close to the support block 10 with a spring a11, the lower part of the moving block 9 is rotatably connected to the connecting plate 14, and the lower part of the connecting plate 14 is rotatably connected to the pushing block 15, the left and right sides of the auxiliary block 3 are fixedly connected to the placing blocks 16, the inside of the placing block 16 is slidably connected with the auxiliary rod 18, and the top of the placing block 16 is fixedly connected to the spring c17.

[0039] Specifically, during the flight, since the drone needs to be lifted or adjusted, this will cause the recorder body 2 to shake. At this time, the auxiliary block 3 will move upward, driving the four push blocks 15 to move upward, and then fold through the connecting plate 14 that is rotatably connected to it, and drive the moving block 9 to slide on the periphery of the fixed rod 12. Since the two moving blocks 9 are fixed with springs b13 on the separated side and springs a11 on the adjacent side, the entire auxiliary block 3 is slowed down by springs a11 and b13 while the moving block 9 slides left and right, thereby slowing down the shaking of the recorder body 2. At the same time, a damper is provided in the middle of the auxiliary block 3, and the placement block 16 slides on the periphery of the auxiliary rod 18. The auxiliary rod 18 is sleeved with a spring c17, and then the auxiliary block 3 is further slowed down by the damper and spring c17, thereby improving the slowing effect and reducing the damage to the recorder body 2 due to shaking.

[0040] The tops of the two moving blocks 9 are fixedly connected to the inner top wall of the connecting block 1 , and the bottoms of the two pushing blocks 15 are fixedly connected to the top of the auxiliary block 3 .

[0041] Specifically, the moving block 9 is slowed down by the spring a11 and the spring b13 , and the pushing block 15 is slowed down by the connecting plate 14 , so as to slow down the auxiliary block 3 and reduce the shaking of the recorder body 2 .

[0042] The upper ends of the two springs c17 are fixedly connected inside the connection block 1, and the upper and lower ends of the auxiliary rod 18 are fixedly connected inside the connection block 1.

[0043] Specifically, the mitigation effect is improved by the cooperation between the placement block 16 and the spring c17.

[0044] Working principle: When the staff uses this device, first fix the connecting block 1 to the lower part of the drone, then turn the knob 19 to drive the bevel gear 1 20 to rotate, and then drive the bevel gear 2 21 meshing with it to rotate, and drive the bidirectional screw 4 to rotate. Since the bidirectional screw 4 is threadedly connected with the two sliders 5 on the left, and the two sliders 5 on the right slide on the outer periphery of the slide bar 6, the two fixed blocks 7 are driven to move to the front and rear sides of the auxiliary block 3. Then the staff places the recorder body 2 on the middle inner wall of the auxiliary block 3 through the mounting plate 8, and turns the knob 19 at the same time, thereby driving the two fixed blocks 7 to clamp the bottom of the mounting plate 8, and clamp the recorder body 2 through the anti-skid plate on the side close to the two fixed blocks 7, and then fix the recorder body 2, so as to facilitate the staff to install it;

[0045] During the flight, since the drone needs to be lifted or adjusted, this will cause the recorder body 2 to shake. At this time, the auxiliary block 3 will move upward, driving the four push blocks 15 to move upward, and then fold through the connecting plate 14 rotatably connected to it, and drive the moving block 9 to slide on the periphery of the fixed rod 12. Since the two moving blocks 9 are fixed with springs b13 on the separated side and springs a11 on the adjacent side, the entire auxiliary block 3 is slowed down by springs a11 and b13 while the moving block 9 slides left and right, thereby slowing down the shaking of the recorder body 2. At the same time, a damper is provided in the middle of the auxiliary block 3, and the placement block 16 slides on the periphery of the auxiliary rod 18. The outer periphery of the auxiliary rod 18 is provided with a spring c17, and then the auxiliary block 3 is further slowed down by the damper and spring c17, thereby improving the slowing effect and reducing the damage to the recorder body 2 due to shaking.
