Embodiment 1
[0028] A liftable projector using a new generation of information technology, such as Figure 1-3 As shown, it includes a mounting plate 1, a connecting block 2, a connecting cylinder 3, a telescopic cylinder 4, a compression spring 5, a mounting frame 6, a projector 7, a wire assembly 8 and a rotating assembly 9, and the four outer sides of the mounting plate 1 Connecting blocks 2 are connected at the corners, two connecting cylinders 3 are symmetrically connected on the top of the mounting plate 1, and a telescopic cylinder 4 is slidably connected in the connecting cylinder 3, and an installation frame 6 is connected between the tops of the two telescopic cylinders 4. A compression spring 5 is connected between the installation frame 6 and the connecting cylinder 3, a projector 7 is placed in the installation frame 6, and a pay-off assembly 8 and a rotation assembly 9 are respectively installed on the top of the installation plate 1, and the rotation assembly 9 and the releas...
Embodiment 2
[0033] On the basis of Example 1, such as figure 1 , Figure 4 , Figure 5 and Image 6 As shown, a fixing assembly 10 is also included, and the fixing assembly 10 includes a first sliding frame 102, a clamping plate 103, a return spring 104, a wedge block 105, a wheel disc 106, a first torsion spring 107, a first connecting rod 108 and a first connecting rod 108. Two connecting rods 109, four chutes 101 are symmetrically arranged on the top of the mounting plate 1, and the first sliding frame 102 is slidably connected in the chute 101, and the top of the first sliding frame 102 is connected with a clamping plate 103, and the clamping plate 103 and the sliding The plate 92 cooperates, two return springs 104 are connected between the first sliding frame 102 and the mounting plate 1, the wedge-shaped block 105 is connected to the inner surface of the clamping plate 103, the wedge-shaped block 105 cooperates with the sliding plate 92, and the top of the mounting plate 1 is symmet...
Embodiment 3
[0036] On the basis of Example 2, such as figure 1 , Figure 4 and Figure 5 As shown, a buffer assembly 11 is also included. The buffer assembly 11 includes a second fixed plate 111, a second sliding frame 112, a buffer spring 113 and a supporting plate 114. The left front side and the right rear side of the top of the installation plate 1 are connected with a second The fixed plate 111, the second fixed plate 111 is slidably connected with the second sliding frame 112, and there are two buffer springs 113 symmetrically connected between the second sliding frame 112 and the second fixed plate 111. A supporting plate 114 is connected, and the supporting plate 114 cooperates with the installation frame 6 .
[0037] When the mounting frame 6 moves down quickly, the mounting frame 6 can be supported by the supporting plate 114, thereby through the cooperation of the second sliding frame 112, the buffer spring 113 and the supporting plate 114, the mounting frame 6 can be damped,...
