[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] A quick disassembly connector for surveying and mapping equipment for unmanned aerial vehicles, the connector includes a locking fixture 1 and a locking block 10. When in use, the locking block 10 is locked in the locking fixture. When disassembling, it only needs to be simply disassembled. The specific implementation method is as follows:

[0028] A locking groove 2 is arranged in the middle of the locking clamp 1, and the locking groove 2 is an A-type structure. Similarly, the locking block 10 is also an A-type structure that matches the locking groove 2; in this embodiment, the locking groove 2 has 60-degree inclined surfaces on both sides, so that the opening of the locking groove 2 is relatively large, which saves time and effort during disassembly and assembly; the locking groove 2 opens upward, and the locking groove 2 is a structure with one end open and the other end closed. A slide groove 3 is opened on the locking clamp 1, and the slide groove 3 is a top opening structure. A cover plate 18 is detachably arranged at the opening, and one end of the slide groove 3 is closed and the other end is connected to the locking clamp 1. The slots 2 are connected, and a block 4 matching the slot 3 is arranged in the slot 3. A step is arranged at one end of the slot 3 close to the locking slot 2 to prevent the block 4 from sliding out of the slot 3 due to excessive travel, and the block 4 is clamped at the port with the step surface, so that the block 4 can only move within a specific range, that is, the width of the end of the slot 3 close to the locking slot 2 is smaller than the end away from the locking slot 2; a square through hole 5 is opened in the middle of the block 4, and a socket 6 is opened on the locking fixture 1 at the end of the through hole 5 away from the locking slot 2, and a threaded hole coaxial with the socket 6 is opened on the locking fixture 1 7, a stepped shaft 8 is inserted into the threaded hole 7, and a thread is provided in the middle of the stepped shaft 8. A section of the stepped shaft 8 with a thread is screwed into the threaded hole 7. Rotating the stepped shaft 8 can make the threaded end of the stepped shaft 8 screwed into the threaded hole 7, so that the stepped shaft 8 is axially fixed, and reverse rotation can also make the threaded end of the stepped shaft 8 disengage from the threaded hole 7; the end of the stepped shaft 8 close to the through hole 5 is inserted into the insertion hole 6, and the stepped shaft 8 can slide with the block 4 and can rotate relative to the insertion hole 6 on the block 4, between the side wall of the block 4 and the side wall of the slide groove 3, A spring 9 is also sleeved on the step shaft 8. When the threaded end of the step shaft 8 is tightened in the threaded hole 7, the spring 9 is compressed and the block 4 shrinks in the slide groove 3. When the threaded section of the step shaft 8 is disengaged from the threaded hole 7, the spring 9 extends. Under the action of the elastic force of the spring 9, the block 4 moves toward the locking groove 2, and the step shaft 8 also moves with the block 4. In order to facilitate the rotation of the step shaft 8, in this embodiment, a handle 15 is provided at the end of the step shaft 8 away from the block 4. The handle 15 is a cylindrical structure and is also provided with a finger groove.

[0029] The side of the locking block 10 that contacts the end of the clamping block 4 is provided with a clamping groove 11 that matches the clamping block 4, and the locking block 10 and the locking fixture 1 are locked in the clamping groove 11 through the clamping block 4; when the stepped shaft 8 is not axially fixed, the clamping block 4 extends out of the slide groove 3 to the locking groove 2 under the action of the spring, and the end of the clamping block 4 is just stuck in the clamping groove 11, locking the locking block 10 in the locking groove 2; because the bottom of the locking groove 2 is provided with a female socket 16, the top of the locking block 10 is provided with a male socket 17 that matches the female socket 16, and the male socket 17 and the female socket 16 are both 30pin; when the locking block 10 is inserted into the locking groove 2, the female socket 16 is correspondingly inserted into the male socket 17, and the female socket 16 is connected to the power supply of the drone, and the drone's own power supply can be used to provide power for the surveying and mapping equipment installed on the locking block 10. , the surveying and mapping equipment is connected to an independent power supply for lunch break.

[0030] Furthermore, in this embodiment, in order to reduce the center connection of the connector itself as much as possible while ensuring the rigidity of the connector, a plurality of weight-reducing holes 12 are opened in the middle of the locking block 10; at the same time, the locking clamp 1 and the locking block 10 are both made of aluminum alloy or copper alloy.

[0031] Furthermore, in order to further lock the locking block 10 and prevent it from moving, an oblique groove 13 communicating with the locking groove 2 is provided at the bottom, and an edge protrusion 14 matching the oblique groove 13 is provided at the bottom of the locking block 10.

[0032] Furthermore, in order to enable the stepped shaft 8 to rotate relative to the socket 6 and slide with the clamping block 4, in this embodiment, an annular groove 19 is always provided on the inner wall of the socket 6, and a clamping ring 20 that cooperates with the annular groove is provided on the stepped shaft 8; in fact, this structure can also be replaced by a bearing, and a bearing is provided in the socket 6, and the outer cylindrical surface of one end of the stepped shaft 8 is fixed on the inner wall of the inner ring of the bearing, which can also achieve this function.

[0033] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
