[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with the detailed implementation mode.

[0022] As Figure 1 shown, the present utility model provides a technical solution: a low - altitude aircraft with a conveniently disassembled and assembled tripod, including:

[0023] A frame main body 1, a pair of tripod connecting rods 2 are symmetrically arranged at the bottom of the frame main body 1, and a tripod main body 4 is arranged at the bottom of each of the pair of tripod connecting rods 2;

[0024] The tripod main body 4 includes a connecting post 42 arranged at the bottom of the tripod connecting rod 2, a support post 41 is arranged at the bottom of the connecting post 42, a connecting column 421 inserted into the inside of the tripod connecting rod 2 is arranged at the top of the connecting post 42, and an insertion hole 4211 is formed through the side wall of the connecting column 421;

[0025] A locking assembly 3 is arranged between the connecting column 421 and the tripod connecting rod 2. The locking assembly 3 includes a threaded locking rod 31 that penetrates through the tripod connecting rod 2 and is inserted into the insertion hole 4211 inside. A locking nut 32 is arranged on the threaded locking rod 31. This design fixes the connecting column 421 inside the tripod connecting rod 2 by using the threaded locking rod 31 to penetrate through the tripod connecting rod 2 and insert into the insertion hole 4211 of the connecting column 421, and then using the locking nut 32 to cooperate with the threaded locking rod 31, thereby installing the tripod main body 4 on the tripod connecting rod 2. When disassembly is required, just remove the locking nut 32 and pull out the threaded locking rod 31 to make the connecting column 421 separate from the tripod connecting rod 2, thus separating the tripod main body 4 from the tripod connecting rod 2, playing the role of facilitating the disassembly and assembly of the tripod main body 4, and having good use effect.

[0026] Referring to Figure 2 and Figure 3 , a force - applying post 33 is arranged on the side wall of the locking nut 32. This design facilitates applying force to the locking nut 32 by using the force - applying post 33, thereby facilitating the disassembly and assembly of the locking nut 32, and further facilitating the disassembly and assembly of the tripod main body 4.

[0027] Referring to Figure 3 and Figure 4, the threaded locking rod 31 includes a limiting disc 311 provided on the side wall of the tripod connecting rod 2. An insertion post 312 is provided at the end of the limiting disc 311, which penetrates the side wall of the tripod connecting rod 2 and inserts into the internal insertion hole 4211. An external thread 313 is provided on the side wall of the end of the insertion post 312, and the locking nut 32 is matched with the external thread 313. This design facilitates the limitation of the insertion post 312 by using the limiting disc 311 of the threaded locking rod 31. The insertion post 312 is inserted into the insertion hole 4211 of the connecting column 421, and at the same time, it cooperates with the locking nut 32 on the external thread 313, so that the limiting disc 311 and the locking nut 32 clamp the tripod connecting rod 2, thereby fixing the connecting column 421 inside the tripod connecting rod 2 and improving the stability of the fixing point.

[0028] Referring to Figure 1 and Figure 3 , a connecting hole 5 matching the connecting column 421 is opened at the bottom of the tripod connecting rod 2. Symmetrically arranged at the top of the connecting column 42 are positioning posts 43 which are located on both sides of the connecting column 421 and below the insertion hole 4211. Positioning holes 6 matching the positioning posts 43 are opened at the positions corresponding to the positioning posts 43 at the bottom of the tripod connecting rod 2. This design connects the positioning posts 43 with the positioning holes 6 to prevent side-slip between the tripod connecting rod 2 and the connecting column 421 and improve the stability of the connection point.

[0029] Referring to Figure 3 and Figure 4 , a through hole communicating with the connecting hole 5 is opened on the side wall of the tripod connecting rod 2. When the lower end face of the tripod connecting rod 2 fits with the upper end face of the connecting column 42, the axis line of the through hole coincides with the axis line of the insertion hole 4211. The diameter of the insertion post 312 respectively matches the inner diameter of the insertion hole 4211 and the inner diameter of the through hole. The diameter of the limiting disc 311 is larger than the diameter of the insertion post 312. This design makes the axis line of the through hole coincide with the axis line of the insertion hole 4211 when the lower end face of the tripod connecting rod 2 fits with the upper end face of the connecting column 42, thus facilitating the insertion of the threaded locking rod 31 through the through hole of the tripod connecting rod 2 into the insertion hole 4211 of the connecting column 421, accelerating the insertion speed of the threaded locking rod 31 and the speed of fixing the connecting column 421 inside the tripod connecting rod 2, and thus quickly installing the tripod main body 4 on the tripod connecting rod 2.

[0030] Referring to Figure 3 , a pair of support tubes 21 for respectively supporting the ends of the threaded locking rod 31 and the ends of the locking nuts 32 are symmetrically arranged on the side wall of the tripod connecting rod 2. The threaded locking rod 31 penetrates through the support tubes 21. The inner diameter of the support tubes 21 matches the diameter of the insertion post 312. The diameter of the limiting disc 311 is larger than the inner diameter of the support tubes 21. This design increases the contact area and improves the stability of the connection of the limiting disc 311 and the locking nut 32 on the threaded locking rod 31.

[0031] Referring toFigures 1-4 , as an embodiment of the present utility model: when it is necessary to install the tripod main body 4, the staff first inserts the connecting column 421 into the connecting hole 5, and at the same time inserts the positioning column 43 into the positioning hole 6. When the lower end surface of the tripod connecting rod 2 fits with the upper end surface of the connecting column 42, the axis line of the through hole coincides with the axis line of the insertion hole 4211, thereby accelerating the speed of inserting the threaded locking rod 31 into the insertion hole 4211. Then, the insertion column 312 on the threaded locking rod 31 penetrates through the through hole on the support tube 21 and the tripod connecting rod 2 and is inserted into the insertion hole 4211 of the connecting column 421, so that the limiting disc 311 on the threaded locking rod 31 fits with the end of one of the support tubes 21. Then, the locking nut 32 is connected to the external thread 313 on the insertion column 312, and the locking nut 32 fits with the end of the other support tube 21, so that the limiting disc 311 and the locking nut 32 clamp the tripod connecting rod 2, thereby fixing the connecting column 421 inside the tripod connecting rod 2, so as to facilitate the installation of the tripod main body 4 on the tripod connecting rod 2 and improve the stability of the fixing part;

[0032] When it is necessary to disassemble, just remove the locking nut 32 and pull out the threaded locking rod 31 to make the connecting column 421 disengage from the tripod connecting rod 2, so as to facilitate the separation of the tripod main body 4 from the tripod connecting rod 2, thereby playing a role in facilitating the disassembly and assembly of the tripod main body 4, with good use effect and improving the practicability of the present utility model.
