[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices. A UAV drawing design and drawing platform is a work platform specifically designed for designing and drawing UAV drawings. It aims to meet the needs of accurate drawing in the UAV design process and provide important technical support for the research, development, production and maintenance of UAVs.

[0003] When drawing up drone blueprints, staff will lay the blueprints flat on the workbench and then use pressure strips to position the two sides of the blueprints. After the blueprints are fixed in place, staff will carry out drawing work on the blueprints.

[0004] The existing technology has the following drawbacks: In some existing equipment, the positioning of drawings is accomplished by pressure strips. The installation position of the pressure strips is fixed and cannot be adapted to drawings of different specifications. For drawings of different specifications, the pressure strips need to be disassembled and adjusted by the staff. The disassembly and installation of the pressure strips require multiple bolt tightening operations, which are cumbersome, time-consuming and labor-intensive. Therefore, a UAV drawing design and drawing platform is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a drone drawing design and drawing platform, which aims to improve the problem that the existing technology cannot adapt to the use of drawings of different specifications.

[0007] The limiting mechanism includes a threaded rod, with a ring fixedly connected to the outer wall of the threaded rod, and a rectangular plate threadedly connected to the outer wall of the threaded rod. The threaded rod passes through and is slidably connected to the inner wall of the telescopic rod.

[0008] As a further description of the above technical solution:

[0009] The adjustment assembly includes a plug, the outer wall of which is elastically connected to the base via a movable spring, and the plug is slidably connected to the right side wall of the base.

[0010] As a further description of the above technical solution:

[0011] The bottom end of the pressure plate contacts the top end of the drawing board, and the bottom end of the long plate contacts the top end of the drawing board.

[0012] As a further description of the above technical solution:

[0013] The bottom end of the ring is in contact with the upper surface of the telescopic rod.

[0014] As a further description of the above technical solution:

[0015] The connecting block is movably connected through and to the outer wall of the threaded rod.

[0016] As a further description of the above technical solution:

[0017] The rectangular plate is fixedly connected to the outer wall of the drawing board, and the movable frame is slidably connected to the outer wall of the drawing board.

A fixed frame 3 is fixedly connected to the top of the drawing board 2, and a pressure plate 4 is slidably connected through the inner wall of the fixed frame 3. A slot corresponding to the pressure plate 4 is provided on the fixed frame 3 to allow the pressure plate 4 to move vertically. A telescopic rod 5 is fixedly connected to the left side wall of the pressure plate 4. The telescopic rod 5 can adjust its length as the moving frame 6 moves. A long plate 7 is slidably connected to the left end of the telescopic rod 5. A slot corresponding to the telescopic rod 5 is provided on the long plate 7 to allow the telescopic rod 5 to move vertically. The telescopic rod 5 is initially located in the middle of the slot. A connecting block 10 is fixedly connected to the outer wall of the long plate 7. A movable frame 6 is slidably connected through the outer wall of the long plate 7. The movable frame 6 has a slot corresponding to the long plate 7, allowing the long plate 7 to move vertically. A limiting mechanism is provided on the inner wall of the telescopic rod 5. An adjustment component is provided on the right side wall of the base 1. The limiting mechanism includes a threaded rod 8. A ring 9 is fixedly connected to the outer wall of the threaded rod 8. A rectangular plate 11 is threadedly connected to the outer wall of the threaded rod 8. Multiple slots corresponding to the threaded rod 8 are provided on the rectangular plate 11. The slots are provided with threads that match the threaded rod 8. The threaded rod 8 is not initially in a fixed state. The threaded rod 8 is slidably connected through the inner wall of the telescopic rod 5. The middle part of the threaded rod 8 is a smooth surface. The telescopic rod 5 has a slot corresponding to the threaded rod 8, allowing the threaded rod 8 to move vertically.

[0035] Reference Figure 1 , Figure 5 and Figure 6 The adjustment component includes a plug 12. The outer wall of the plug 12 is elastically connected to the base 1 via a movable spring 13. The plug 12 is slidably connected to the right side wall of the base 1. The base 1 has a slot corresponding to the plug 12, allowing the plug 12 to move back and forth. The plug 12 is inserted into the outer wall of the drawing board 2. The round rod of the drawing board 2 has multiple sets of slots corresponding to the plug 12. The plug 12 is initially inserted into the slot. The outer wall of the plug 12 is fixedly connected to one end of the movable spring 13. The other end of the movable spring 13 is fixedly connected to the inner wall of the front end of the base 1. When the plug 12 moves forward, the movable spring 13 is compressed. When resetting, the elastic force of the movable spring 13 is used to reset the plug 12.

[0036] Reference Figures 2-4The bottom end of the pressure plate 4 contacts the top end of the drawing board 2, the bottom end of the long plate 7 contacts the top end of the drawing board 2, and the bottom end of the ring 9 contacts the upper surface of the telescopic rod 5. When the ring 9 contacts and presses the telescopic rod 5, it positions the telescopic rod 5. The connecting block 10 is connected through and movably connected to the outer wall of the threaded rod 8. The upper part of the threaded rod 8 has an annular groove corresponding to the connecting block 10. When the threaded rod 8 rotates, it does not affect the connecting block 10. At the same time, when the threaded rod 8 is not in a fixed state, the connecting block 10 can move vertically along the annular groove. The rectangular plate 11 is fixedly connected to the outer wall of the drawing board 2, and the moving frame 6 is slidably connected to the outer wall of the drawing board 2. The drawing board 2 has a slot corresponding to the moving frame 6, allowing the moving frame 6 to move left and right.

[0037] Working principle: When positioning the drawing, first move the moving frame 6 downwards to the left according to the length of the drawing. The moving frame 6 will move the long plate 7, connecting block 10, threaded rod 8, and ring 9 to the left. The telescopic rod 5 will also adjust its length as the moving frame 6 moves. When the moving frame 6 is adjusted, move the pressing plate 4 upwards. The pressing plate 4 will move the telescopic rod 5 upwards. The telescopic rod 5 will move upwards in the middle of the groove of the long plate 7. At this time, the telescopic rod 5 will not affect the long plate 7. Then, place one side of the drawing into the gap between the pressing plate 4 and the drawing board 2. Then release the pressing plate 4 and use its own weight to... First, perform initial positioning on one side of the drawing. Then, move the long plate 7 upwards with your hand. The long plate 7 will move upwards along the outer wall of the threaded rod 8, along with the connecting block 10. Next, place the other side of the drawing in the gap between the long plate 7 and the drawing board 2. Release the long plate 7 and use its weight to perform initial positioning on the other side of the drawing. Then, rotate the threaded rod 8 counterclockwise. The threaded rod 8 will move downwards along with the ring 9. When the ring 9 contacts and presses the telescopic rod 5, the positioning of the pressure plate 4 is completed. At the same time, the top of the ring groove on the threaded rod 8 will contact and press the connecting block 10, completing the positioning of the long plate 7. At this time, the threaded rod 8 is in the groove of the rectangular plate 11.

[0038] When the limit needs to be released, rotate the threaded rod 8 clockwise. The threaded rod 8 will move the ring 9 upwards, and the ring 9 will no longer release the telescopic rod 5, thus releasing the limit on the pressure plate 4. At the same time, the top of the ring groove on the threaded rod 8 will no longer contact the connecting block 10, thus releasing the limit on the connecting block 10 and the long plate 7. At this time, the threaded rod 8 will separate from the groove of the rectangular plate 11. Then, you can move the pressure plate 4 and the long plate 7 upwards by hand to remove the drawing. If you need to reposition the drawing, simply repeat the above steps.

[0039] When the angle of the drawing board 2 needs to be adjusted, move the insert 12 forward with your hand. The insert 12 will squeeze the movable spring 13. When the insert 12 separates from the slot on the round rod on the drawing board 2, rotate the drawing board 2 with your hand. When the drawing board 2 is adjusted to the required angle, the insert 12 will coincide with the slot on the round rod. Release the insert 12 with your hand, and use the elastic force of the movable spring 13 to insert the insert 12 into the slot, thus completing the limiting of the drawing board 2. If the angle of the drawing board 2 needs to be adjusted again, simply repeat the above operation steps.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
