At this time, the two sets of arc-shaped clamping plates are fixed to the camera to effectively ensure the positioning effect of the outside of the camera, and under the elastic buffering of the sleeve rod, spring and sleeve, the impact and shaking caused by the operation of the UAV to the camera are reduced, and the safety, stability and shooting quality of the camera are improved. The two sets of storage half-grooves are close to form an overall storage space, and a closed frame with protective measures is formed under the camera.

[0004] However, the existing patient transfer equipment used in drones has a problem that the height of the fixed bracket is fixed and cannot be easily adjusted; therefore, it does not meet the existing needs. In this regard, we propose an external fixation bracket device for the injured and sick for drones. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1

[0023] See also Figure 1-3 The present invention provides an embodiment of an external fixation device for an injured person used in a drone, comprising: a drone body 100, a propeller blade mechanism 200 disposed in a circle on the outside of the drone body 100, and six propeller blade mechanisms 200, and two connecting column feet 300 disposed on both sides of the lower end surface of the drone body 100;

[0024] Also includes:

[0025] A fixing plate 101 is installed between the two connecting column feet 300. A controller 400 is provided on the lower end surface of the fixing plate 101. First connecting rods 401 are provided on both sides of the lower end surface of the controller 400, and two pairs of first connecting rods 401 are provided. The upper ends of the two pairs of first connecting rods 401 are rotatably connected to the controller 400 through the first electrically controlled rotating shaft 402. Second connecting rods 404 are provided below the two pairs of first connecting rods 401. The lower ends of the two pairs of first connecting rods 401 are rotatably connected to the upper ends of the second connecting rods 404 through the second electrically controlled rotating shaft 403. Two pairs of second connecting rods 404 are provided, and a bracket plate 500 is provided in the middle below the two pairs of second connecting rods 404.

[0026] Example 2

[0027] See also Figure 1 A hydraulic telescopic rod 40401 is provided at the lower end of the two pairs of second connecting rods 404, and one end of the hydraulic telescopic rod 40401 passes through and extends into the interior of the second connecting rod 404, and the other end of the hydraulic telescopic rod 40401 is rotatably connected to the two ends of the front and rear sides of the bracket plate 500 through the first central rotating shaft 405.

[0028] The setting of the hydraulic telescopic rod 40401 can allow the bracket plate 500 to adjust its upper and lower positions when the first connecting rod 401 and the second connecting rod 404 rotate.

[0029] See also Figure 2 A flip bracket plate 5001 is provided at one end of the bracket plate 500, and the flip bracket plate 5001 rotates with the bracket plate 500 through the second central rotation axis 5002. Handle rods 501 are provided on the front and rear sides of the bracket plate 500, and the lower end surface of the handle rod 501 is provided with a connecting rod 502, and there are several connecting rods 502, and the upper ends of the several connecting rods 502 are fixedly connected to the lower end surface of the handle rod 501.

[0030] The arrangement of the flip support plate 5001 and the second central rotation axis 5002 can reduce the volume of the object when the support plate 500 is not in use, thereby preventing the support plate 500 from being too long and thus being damaged by collision.

[0031] See also Figure 1 and Figure 2 The lower ends of several connecting rods 502 are rotatably connected to the bracket plate 500 through a rotating center axis 503, and several rotating center axes 503 are provided. The inner end surfaces of the bracket plate 500 and the flip bracket plate 5001 are provided with inner grooves 504, and the inner grooves 504 are formed integrally with the bracket plate 500 and the flip bracket plate 5001 respectively.

[0032] The setting of the rotating central axis 503 can make the connecting rod 502 stand upright, thereby effectively providing protection for the bracket plate 500.

[0033] Working principle: When the device is in use, the propeller blade mechanism 200 is used to adjust the position of the drone body 100 and transport it. When the drone body 100 arrives at the required position, the bracket plate 500 can be moved downward by rotating the first electrically controlled rotating shaft 402, the second electrically controlled rotating shaft 403 and the first central rotating shaft 405. After moving downward, the flip bracket plate 5001 is unfolded through the second central rotating shaft 5002, and the patient is placed in the inner groove 504 inside the bracket plate 500 and the flip bracket plate 5001. After the placement is completed, the handle rod 501 is lifted upward to make the connecting rod 502 rotate along with the rotating center axis 503, so that both sides of the bracket plate 500 can be protected.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
