Description
Technical Field
[0001] The utility model belongs to the technical field of surveying instrument installation, and specifically refers to a surveying instrument fixing device for unmanned aerial vehicle surveying and mapping. Background Art
[0002] In the field of drone mapping, the stability of the connection between the surveyor and the drone is directly related to the accuracy of surveying data and operational safety. Current fixtures on the market suffer from the following common flaws: Traditional snap-fit structures only provide single-direction fixation, making it difficult to ensure both axial and radial stability. In complex flight environments, the surveyor is easily displaced by turbulence. Some fixtures that use flexible straps can become loose due to the vibrations of the drone during flight, affecting data accuracy and posing a risk of equipment falling off. Furthermore, most fixtures lack a buffering design, making them unable to withstand external shocks that could damage precision surveying instruments.
[0003] Therefore, developing a fixing device for UAV surveying instruments that combines stable fixation, convenient operation and protective functions has become an urgent task to meet the needs of efficient and accurate surveying and mapping operations. Utility Model Content
[0004] The utility model overcomes the shortcomings of the existing technology and provides a surveying instrument fixing device for unmanned aerial vehicle surveying and mapping. A mechanical locking structure is formed by the cooperation of a self-locking cone disk and a self-locking cone rod to achieve axial fixation, and a radial clamping force is generated by the inflation of the airbag to achieve two-way stable fixation. At the same time, the airbag has both buffering and protection functions, which improves the convenience of operation and equipment protection while ensuring the stability of the fixation.
[0005] The technical solution adopted by the utility model is as follows: This solution provides a surveying instrument fixing device for unmanned aerial vehicle surveying and mapping, including a drone body and a surveying machine body, the surveying machine body is snap-connected to the bottom wall of the drone body, a snap chamber is fixedly provided on the bottom wall of the drone body, and a self-locking cone rod is slidably provided on the side wall of the snap chamber; a self-locking cap is fixedly provided on the top wall of the surveying machine body, and the self-locking cap is in conflict with the self-locking cone rod.
[0006] Furthermore, a piston plate is slidably provided in the buckle chamber, an airbag is fixedly provided on the bottom wall of the buckle chamber, and the interior of the airbag is communicated with the interior of the buckle chamber.
[0007] Furthermore, a driven rod is fixedly provided on the bottom wall of the piston plate, and the driven rod is in conflict with the self-locking cap.
[0008] Furthermore, the self-locking cap includes a mounting post, a self-locking cone disc and an unlocking cone disc; the mounting post is fixedly arranged on the top wall of the surveying and mapping machine body, the mounting post is in contact with the driven rod, a fixing post is fixedly provided on the circumferential wall of the mounting post, the self-locking cone disc is fixedly arranged on the top end of the mounting post, and the unlocking cone disc is slidably arranged on the circumferential wall of the mounting post.
[0009] The beneficial effects achieved by the utility model using the above structure are as follows:
[0010] (1) Push the self-locking cap into the buckle chamber and push it upward, so that the self-locking cone disc and the self-locking cone rod form a mechanical lock, providing a stable support for the surveying machine body, which can effectively resist the downward pulling force generated by the UAV during flight and avoid the risk of the surveying machine body falling off; when unlocking, push the surveying machine body upward again, and the first return spring will automatically release the return force, shortening the time required for installation and removal of the surveying machine;
[0011] (2) When the self-locking cap is pushed upward, the piston plate presses the gas in the buckle chamber into the airbag. After the airbag expands, it generates a radial clamping force, forming a buffer layer on the outside of the surveying and mapping machine body, which can absorb the bumps and vibrations encountered by the UAV during flight and enhance the stability of the surveying and mapping machine body during flight;
[0012] (3) The airbag fits tightly to the surveying machine body, blocking external debris from the chamber, avoiding wear or failure of the surveying machine due to collision with debris, and extending the service life of the surveying machine body. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0021] Example 1: Please refer to Figure 1-Figure 5 The present embodiment provides a surveying instrument fixing device for unmanned aerial vehicle surveying and mapping, comprising an unmanned aerial vehicle body 1 and a surveying machine body 2, the surveying machine body 2 being snap-connected to the bottom wall of the unmanned aerial vehicle body 1; a snap-on chamber 3 is fixed on the bottom wall of the unmanned aerial vehicle body 1, a self-locking cone rod 4 is slidably provided on the side wall of the snap-on chamber 3, the end of the self-locking cone rod 4 is flat, a second return spring 15 is fixed on the side wall of the self-locking cone rod 4, the other end of the second return spring 15 is fixedly connected to the inner wall of the snap-on chamber 3, a piston plate 6 is slidably provided in the snap-on chamber 3, an air bag 7 is fixed on the bottom wall of the snap-on chamber 3, an air supply pipe 8 is opened in the side wall of the snap-on chamber 3, the air supply pipe 8 communicates with the inside of the snap-on chamber 3 and the inside of the air bag 7, a driven rod 9 is fixed on the bottom wall of the piston plate 6, a first return spring 10 is fixed on the top wall of the piston plate 6, the top of the first return spring 10 is fixed to the snap-on chamber The top wall of the chamber 3 is fixedly connected; a self-locking cap 5 is fixedly provided on the top wall of the surveying and mapping machine body 2, and the self-locking cap 5 includes a mounting post 11, a self-locking cone disc 12 and an unlocking cone disc 13; the mounting post 11 is fixedly provided on the top wall of the surveying and mapping machine body 2, the mounting post 11 conflicts with the driven rod 9, and a fixing post 14 is fixedly provided on the circumferential wall of the mounting post 11. The diameter of the fixing post 14 and the unlocking disc 13 are the same as the width of the surveying and mapping machine body 2. During movement, they are in contact with the side wall of the airbag 7 and will not be stopped by the airbag 7. The self-locking cone disc 12 is fixedly provided on the top of the mounting post 11, and the unlocking cone disc 13 is slidably provided on the circumferential wall of the mounting post 11. The unlocking cone disc 13 is located between the self-locking cone disc 12 and the fixing post 14. The diameter of the unlocking cone disc 13 is larger than the diameter of the self-locking disc 12. A groove 16 is provided on the top wall of the unlocking cone disc 13, and the diameter of the groove 16 is the same as that of the self-locking disc 12.
[0022] The working principle of this solution is as follows: after the self-locking cap 5 is pushed into the buckle chamber 3, the mounting column 11 pushes the piston plate 6 upward through the driven rod 9, and simultaneously drives the self-locking cone disc 12 to move upward. The self-locking cone disc 12 pushes the self-locking cone rod 4 through the inclined surface. When the self-locking cone disc 12 completely passes over the self-locking cone rod 4, the self-locking cone rod 4 and the bottom surface of the self-locking cone disc 12 fit together to form a mechanical lock to achieve axial fixation. At the same time, the piston plate 6 moves upward to squeeze the gas in the buckle chamber 3 and fill the air bag 7 through the air supply pipe 8, causing the air bag 7 to expand. The surveying and mapping machine body 2 is wrapped to generate radial clamping force and form a buffer layer; when unlocking, the surveying and mapping machine body 2 is pushed up again, and the unlocking cone disc 13 pushes the self-locking cone rod 4 through the inclined surface. When the unlocking cone disc 13 completely passes over the self-locking cone rod 4, the first return spring 10 is reset to push the piston plate 6 downward to drive the surveying and mapping machine body 2 downward. The gas in the airbag 7 flows back and contracts to release the radial clamping. Finally, the self-locking cone disc 12 and the unlocking cone disc 13 are separated from the constraint of the self-locking cone rod 4, so that the surveying and mapping machine body 2 is released and removed.
[0023] In this embodiment, before installation, the piston plate 6 is located at the bottom of the buckle chamber 3 under the natural extension of the first return spring 10, and the self-locking cone rod 4 is extended into the buckle chamber 3 under the thrust of the second return spring 15, and the airbag 7 is in an uninflated contracted state. During installation, the operator holds the surveying machine body 2 and aligns the self-locking cap 5 on the top of the surveying machine body 2 with the opening of the buckle chamber 3 on the bottom wall of the drone body 1. Then, the surveying machine body 2 is slowly pushed upward to allow the self-locking cap 5 to gradually enter the buckle chamber 3. When the mounting post 11 completely enters the buckle chamber 3, the top of the mounting post 11 begins to contact the driven rod 9 on the bottom wall of the piston plate 6. As the surveying machine body 2 continues to be pushed upward, the mounting post 11 generates an upward thrust on the driven rod 9, and the driven rod 9 transmits this force to the piston plate 6, prompting the piston plate 6 to overcome the elastic force of the first return spring 10 and move upward. The first return spring 10 is gradually compressed to store elastic potential energy.
[0024] As the piston plate 6 moves upward, the self-locking cone disc 12 at the top of the mounting column 11 also moves upward. When the inclined surface of the self-locking cone disc 12 contacts the self-locking cone rod 4, due to the guiding effect of the inclined surface, the self-locking cone disc 12 will generate a lateral force on the self-locking cone rod 4 away from the axial center of the buckle chamber 3. The self-locking cone rod 4 slides along the sliding track of the side wall of the buckle chamber 3 in the direction away from the axial center of the buckle chamber 3, and at the same time compresses the second return spring 15 to store elastic potential energy.
[0025] As the surveying and mapping machine body 2 continues to be pushed upward, the self-locking cone disc 12 completely passes over the self-locking cone rod 4. At this time, the self-locking cone rod 4 loses the lateral force of the self-locking cone disc 12, and the second return spring 15 immediately releases its elastic potential energy, pushing the self-locking cone rod 4 to return to the axial direction of the buckle chamber 3. After resetting, the upper wall plane of the self-locking cone rod 4 is tightly fitted with the bottom wall of the self-locking cone disc 12, forming a mechanical locking structure, which fixes the surveying and mapping machine body 2 axially in the buckle chamber 3 to prevent it from falling off downward.
[0026] During the upward movement of the piston plate 6, the gas in the snap chamber 3 is squeezed by the piston plate 6 and pressed into the airbag 7 through the air supply pipe 8 on the side wall. As the gas continues to be filled, the airbag 7 gradually expands until it is tightly wrapped around the surveying and mapping machine body 2. The expanded airbag 7 not only generates a radial clamping force on the surveying and mapping machine body 2, effectively preventing it from shaking during the flight of the drone body 1, but also forms a buffer layer between the surveying and mapping machine body 2 and the inner wall of the snap chamber 3, preventing external debris from entering the snap chamber 3 and causing collision damage to the surveying and mapping machine body 2.
[0027] When the surveying and mapping machine body 2 needs to be removed, the operator pushes the surveying and mapping machine body 2 upward again, so that the mounting column 11 drives the self-locking cap 5 to continue to move upward. At this time, the inclined surface of the self-locking cone rod 4 contacts the upper edge of the unlocking cone disk 13. The unlocking cone disk 13 also generates a lateral force on the self-locking cone rod 4 away from the axial center of the buckle chamber 3, pushing the self-locking cone rod 4 to slide outward again and compressing the second return spring 15.
[0028] As the surveying machine body 2 continues to push up, the self-locking cone rod 4 gradually passes over the top of the unlocking cone disc 13. When the self-locking cone rod 4 completely passes over the unlocking cone disc 13, the first return spring 10 releases the elastic potential energy stored before, pushing the piston plate 6 to move downward. The piston plate 6 drives the driven rod 9 to move downward, pushing the bottom end of the self-locking vertebral disc 12 into the groove 16, and then pushing the surveying machine body 2 downward through the mounting column 11. The lower inclined surface of the unlocking cone disc 13 contacts the self-locking cone rod 4, and continues to apply lateral force to the self-locking cone rod 4. At this time, the unlocking cone disc 13 is in close contact with the self-locking cone disc 12, and the diameter of the unlocking cone rod 13 is larger than that of the self-locking cone rod 4. The disc 12 is formed on the upper surface of the self-locking cone 12, and the bottom end of the self-locking cone 12 is located in the groove 16. When the unlocking cone disc 13 passes over the self-locking cone rod 4, the second return spring 15 pushes the self-locking cone rod 4 to move toward the self-locking disc 12 again. The end plane of the self-locking cone rod 4 directly passes over the bottom end of the self-locking cone 12, and the end of the self-locking cone rod 4 contacts the upper inclined surface of the self-locking disc 12, so that the unlocking cone disc 13 is out of contact with the self-locking cone rod 4. In the process of the piston plate 6 moving downward, the air pressure in the buckle chamber 3 is reduced, and the gas in the airbag 7 flows back to the buckle chamber 3 through the air supply pipe 8. The airbag 7 gradually shrinks, releasing the radial clamping force on the surveying and mapping machine body 2.
[0029] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
