[0017] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0018] like Figure 1 As shown, an embodiment of the quick-release mounting bracket for small electronic devices of this utility model includes a mounting plate 1. A connecting shaft 2 is hinged to one end of the mounting plate 1, and a locking sleeve 2-1 is threaded onto the connecting shaft 2. The upper surface of the mounting plate 1 has a strip-shaped mounting groove 1-2, with the end of the strip-shaped mounting groove 1-2 away from the connecting shaft 2 forming a wedge shape 1-3. One end of the mounting plate 1 has a pair of connecting ears 1-1, and the connecting shaft 2 is hinged between the pair of connecting ears 1-1. To fix the mounting plate 1 to the aircraft equipment rack, the mounting plate 1 has recessed platforms on both sides, and through holes 1-4 are provided at the four corners of the recessed platforms. During installation, the mounting plate 1 is first fixed to the aircraft equipment rack by screws passing through the four through holes 1-4. The aircraft equipment rack then bears the weight of the small electronic device 3. The locking sleeve 2-1 mainly serves to fix the position. During disassembly, the mounting plate 1 does not need to be removed from the aircraft equipment rack, achieving the purpose of quick loading and unloading. To further reduce the weight of the mounting bracket 1, a strip mounting groove 1-2 penetrates the mounting plate 1, and a long strip weight-reducing groove 1-5 is provided on the back of the mounting plate 1.

[0019] like Figure 2 As shown, this embodiment also includes a wedge-shaped latch 3-1 that is adapted to the wedge shape 1-3 and fixed on the bottom surface of the small electronic device 3, and a positioning pin 3-2 that is fixed on the end surface of the small electronic device 3, and the positioning pin 3-2 is located at the end away from the wedge-shaped latch 3-1.

[0020] like Figure 3 As shown, when the small electronic device 3 is placed on the mounting plate 1, the wedge-shaped latch 3-1 can be inserted into the wedge 1-3 along the strip mounting groove 1-2. The locking sleeve 2-1 rotates upward to insert the positioning pin 3-2 into its inner cavity and rotates to lock it. The two side walls of the wedge 1-3 are inwardly inclined slopes, making the upper end of the wedge 1-3 smaller than the lower end. The two outer side walls of the wedge-shaped latch 3-1 fit closely with the slopes, locking the wedge-shaped latch 3-1 in the wedge 1-3 and preventing it from moving upward.

[0021] like Figure 4 As shown, a locking sleeve 2-2, which can only move axially but not rotate, is also fitted on the connecting shaft 2. The locking sleeve 2-2 is located outside the locking sleeve 2-1, and the opposing surfaces of the locking sleeve 2-2 and the locking sleeve 2-1 are engaged by helical teeth. A tension spring 2-3 is also provided in the inner cavity of the locking sleeve 2-2. The two ends of the tension spring 2-3 are connected to the locking sleeve 2-2 and the locking sleeve 2-1 respectively, so that the helical teeth are kept engaged to prevent the locking sleeve 2-1 from retracting.
