[0031] The top of scissors fork frame 44 is movably connected with second limiting sliding plate 45, and second limiting sliding plate 45 is fixed at the bottom of top cover 3;Between adjacent side plates 4, a lifting assembly is arranged, the lifting assembly is used for lifting projector, and the lifting assembly includes tray 5, one side of tray 5 near side plate 4 is fixed with limiting shaft 51, limiting shaft 51 extends into side plate 4 and is rotatably connected with it, one side of tray 5 not provided with limiting shaft 51 is fixed with locking screw 52, locking screw 52 penetrates and extends out from the side plate 4 near it, and the extended part of locking screw 52 is screw-connected with nut;

[0032] One side of tray 5 near locking screw 52 is screw-connected with adjusting screw 53, one side of tray 5 near limiting shaft 51 is slidably connected with sliding rod 54, the top of adjusting screw 53 and sliding rod 54 is rotatably connected with limiting frame 55, the inside of limiting frame 55 is provided with inner sliding groove 56, the inside of inner sliding groove 56 is slidably connected with clamping plate 6 on both sides, the bottom of two clamping plates 6 is fixed with a group of suction cups 61, and the suction cups 61 are communicated with clamping plate 6, the surface of clamping plate 6 is screw-connected with filling screw 62, the bottom of filling screw 62 is fixed with rubber pad 63, rubber pad 63 penetrates suction cup 61, and the both ends of clamping plate 6 are fixed with baffle;

[0033] In the specific operation process, first, the fixed seat 1 is fixed on the ceiling through the bolt, then the rotating shaft 2 is clamped into the inside of the installation clamping groove 11, then the limiting screw 12 is inserted into the fixed seat 1 and tightened, so that the rotating shaft 2 is limited in the inside of the installation clamping groove 11, thereby the installation of the utility model can be completed;

[0034] Specifically, as Figure 2As shown, when the projector needs to be installed, first start the motor 34 through the controller, drive a rope reel 33 to rotate clockwise, and drive another rope reel 33 to rotate counterclockwise, then make the two rope reels 33 reverse rotation synchronously, release the steel wire rope 331, in the process of releasing the steel wire rope 331, the two side plates 4 lose the upward lifting tension of the steel wire rope 331, and gradually descend under the influence of their own gravity and the gravity of the tray 5, in the process of descending, the two scissors frames 44 gradually unfold, and the tray 5 descends with the side plates 4, thereby shortening the distance between the tray 5 and the ground, then the projector can be installed on the surface of the tray 5, thereby reducing the risk of installing the tray 5 at a high place;

[0035] When the projector is placed on the surface of the tray 5, rotate the adjusting screw 53, make the adjusting screw 53 drive the limit frame 55 connected at the top end to move towards the ground, then drive the two clamping plates 6 connected inside the limit frame 55 to move towards the ground synchronously, then make the two clamping plates 6 drive the limit frame 55 connected at the top end of the slide rod 54 to move towards the ground synchronously, then make the limit frame 55 drive the slide rod 54 to move towards the ground, that is, the adjusting screw 53 can drive the two limit frames 55, the two clamping plates 6 and the slide rod 54 to move up and down synchronously;

[0036] In the process of moving the two clamping plates 6 towards the ground, the two clamping plates 6 gradually approach the tray 5, that is, the two clamping plates 6 gradually approach the projector on the top of the tray 5, in the process of moving, the clamping plate 6 drives the suction cup 61 to approach the projector, until the suction cup 61 contacts the projector, then manually adjust the two clamping plates 6 to slide inside the inner sliding groove 56, so that the two clamping plates 6 move above the projector, then continue to rotate the adjusting screw 53, make the adjusting screw 53 continue to drive the two limit frames 55 and the two clamping plates 6 to approach the projector, make the clamping plate 6 drive the suction cup 61 to continue to move towards the projector, until the air in the suction cup 61 is excluded by the reverse extrusion of the projector, then make the clamping plate 6 and the suction cup 61 cooperate with the tray 5 to clamp and fix the projector, then make the projector completely fixed on the top of the tray 5;

[0037] Further, after the installation of the projector is completed, when angle adjustment is needed, first rotate the nut outside the locking screw 52, thereby making the tray 5 and the two side plates 4 change from the fixed state to the active state, at this time, the tray 5 can be flipped, the tray 5 is flipped and angle adjusted, since the projector is fixed on the top of the tray 5, then the projector follows the tray 5 to adjust the angle synchronously, thereby completing the adjustment of the longitudinal projection angle of the projector;

[0038] Further, when adjusting the longitudinal projection angle of the projector, since the tray 5 is in a rotating connection state with the two side plates 4 under the action of the limiting shaft 51 and the locking screw 52, and the nut outside the locking screw 52 is released, the tray 5 can be adjusted in the longitudinal full angle in the middle position of the two side plates 4, and then the projection lens of the projector can be completely directed to the ground during the adjustment of the angle, so that the projector can be top projected, thereby improving the comprehensiveness of the projection of the projector.

[0039] Meanwhile, after the longitudinal angle adjustment is completed, the tray 5 can be directly rotated for transverse adjustment, and the limiting shaft 51 and the locking screw 52 are linked to synchronously rotate the two side plates 4 transversely, since the first limiting slide plate 43 is fixed inside the receiving cavity 41, and the second limiting slide plate 45 is fixed at the bottom of the two sides of the top cover 3, and the first limiting slide plate 43 and the second limiting slide plate 45 are connected through the scissors frame 44, so when the side plate 4 is synchronously rotated transversely with the tray 5, the side plate 4 drives the first limiting slide plate 43 and the scissors frame 44 to link the second limiting slide plate 45 and the top cover 3 to synchronously rotate transversely, so that the top cover 3 drives the rotating shaft 2 to rotate transversely inside the mounting clamping groove 11, thereby completing the transverse angle adjustment of the projector.

[0040] After the transverse and longitudinal angles of the projector are adjusted, the motor 34 is started again, and the motor 34 is controlled to reverse, so that the two rope winders 33 are reversed by the motor 34, so that the steel wire rope 331 is wound back by the rope winder 33, and then the steel wire rope 331 drives the side plate 4 and the tray 5 to return, until the specified projection height is reached, the motor 34 is paused, and projection is performed, after the projection is completed, the turning angle of the tray 5 and the top cover 3 can be reset, after the reset is completed, the motor 34 is reversed, the rope winder 33 is controlled to reverse, and the steel wire rope 331 is completely recovered, and then the height of the side plate 4 is reset, so that the side plate 4 drives the tray 5 to reset, after the side plate 4 and the tray 5 are completely reset, a frame is formed with the top cover 3, and the projector is hidden in the frame, thereby reducing the space occupancy of the projector and the utility model.

[0041] It should be noted that the limiting screw 12 only limits the sliding movement of the rotating shaft 2, and the rotating shaft 2 can still rotate inside the mounting clamping groove 11, and after the air in the suction cup 61 is discharged, the suction cup 61 can not only clamp and fix the projector with the tray 5, but also can adsorb the surface of the projector, thereby making the projector more stable during the turning process, and the clamping plate 6 and the tray 5 can clamp projectors of different sizes and thicknesses, thereby improving the applicability of the utility model.

[0042] When the fixing of the projector is released in the later stage, the above steps are followed, and the motor 34 is started again to drive the linkage side plate 4 and the tray 5 to lower the projector. When the projector is lowered, the filling screw 62 is rotated and removed, and the rubber pad 63 is removed by the filling screw 62. Air enters the inside of the suction cup 61 through the clamping plate 6, thereby releasing the suction of the suction cup 61 to the projector. At this time, the adjusting screw 53 is rotated in the opposite direction to release the fixing of the two limiting frames 55 and the two clamping plates 6 to the projector, and then the projector can be removed.

[0043] Embodiment two:

[0044] The inside of the sliding rod 54 is provided with an adjusting groove 7, and the inside of the adjusting groove 7 is slidably connected with a movable support 71. The inside of the movable support 71 is provided with an embedded groove 72, and the inner wall of the embedded groove 72 is fixedly provided with a spring 73. One end of the spring 73 is externally fixedly provided with a heat sink 74, and the heat sink 74 is slidably connected with the embedded groove 72.

[0045] In the specific operation process, on the basis of embodiment one, when the projector is placed on the top of the tray 5 and fixed, the side of the projector close to the heat dissipation port is directed to the heat sink 74, and the projector is abutted with the heat sink 74. Then the adjusting screw 53 is rotated to drive the two limiting frames 55 and the two clamping plates 6 to approach the projector until the two 66 and the tray 5 clamp and fix the projector.

[0046] Further, in the actual use process of the projector, heat is generated by the projector, and the heat is discharged to the outside through the heat dissipation port. When the heat is discharged, the heat sink 74 is in contact with the surface of the projector, so that the heat of the projector is accelerated to be discharged under the cooperation of the heat sink 74, thereby improving the heat dissipation efficiency of the projector in the actual use process.

[0047] It should be noted that in the adjusting and lifting process of the adjusting screw 53, the two limiting frames 55 and the two 66 are synchronously adjusted and lifted. In the lifting process of the limiting frame 55, the sliding rod 54 is synchronously lifted and moved. Since the inside of the sliding rod 54 is provided with the adjusting groove 7, and the movable support 71 is located above the tray 5, the movable support 71 drives the heat sink 74 to always be located above the tray 5 and abutted with the tray 5 in the adjusting and lifting process of the sliding rod 54.

[0048] In the installation of the projector, the position of the heat sink 74 in the embedded groove 72 is adjusted by the spring 73 to ensure that the heat sink 74 can always be attached to the surface of the projector. In the use process of the projector, the heat emitted from the surface of the projector can be accelerated to be discharged through the heat sink 74, and the heat can be transferred to the air through the air holes provided at the top of the embedded groove 72, thereby improving the heat dissipation effect of the projector in use.

[0049] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
