The spherical hinge 3 is structured as shown in fig. 4 and 5, and comprises a hinge ball 31, a hinge cover 32, a hinge base 33 and a hinge rod 34; the hinge ball 31 is positioned in a spherical cavity formed by the matching of the hinge cover 32 and the hinge base 33; the hinge ball 31 is connected with one end of a hinge rod 34; the free end 341 of the hinge rod 34 connected with the hinge seat 33 and the upright post 4 is connected with the bracket body 2 or the support 6;

the locking structure 9, as shown in fig. 4 and 5, includes a threaded through hole 91 (threads of which are not shown) on the sidewall of the hinge base 33, a screw 92 matching the threaded through hole 91, and a knob 93 coupled to the screw 92.

The telescopic upright post 4 is structurally shown in fig. 6 and 7 and is formed by sleeving tubular upright post sections 41 with the wall thickness of 0.3cm and made of 3 sections of PP plastics, and the outer diameters of the three upright post sections 41 from top to bottom are 3.6cm, 4.3cm and 5cm respectively; two upright post sections 41 with the diameters of 4.3cm and 5cm are respectively provided with a locking mechanism 42 at a position 5cm away from the upper end; in the present embodiment, the locking mechanism 42 is shown in fig. 7, and includes a column hole 43 with a thread on the column section 41 and a column screw 44 matching with the column hole, and the other side of the column screw 44 is connected with a column knob 45;

in the embodiment, a vacuum chuck with the diameter of 25cm is adopted as the support 6; regarding vacuum chuck as support 6 in this embodiment mainly to consider that the place that the projecting apparatus used is mostly the ground of mating formation such as ceramic tile or timber apron, adopts vacuum chuck can further improve the installation rate of support. Other support forms such as tripods may be used in other embodiments.

The specific working principle is as follows: in use, a user first attaches the bracket to a paved ground or a top surface of a building through the support 6 (i.e., the vacuum chuck). Then, the user rotates the upright post knob 45 and drives the upright post screw 44 to rotate, each locking mechanism 42 on the upright post 4 is loosened, and the elongation of the upright post section 41 is adjusted, so that the height of the upright post 4 reaches the height required by the user; the user rotates the upright knob 45 in the reverse direction to drive the upright screw 44 to lock the position of each upright joint 41, thereby completing the height adjustment of the upright 4. Then, a user manually pushes the fixing pieces 1 to move towards the edge of the bracket body 2 along the guide rail 8, each row of paired fixing pieces 1 are far away from each other, pressure is generated on the spring 7, and the spring 7 which is originally in a free state is compressed; then, the user releases the fixing piece 1 after placing the projector on the bracket body 2, and the compressed spring 7 generates thrust for the fixing piece 1 to move towards the middle part of the bracket body 2 along the guide rail 8; the fixing piece 1 moves towards the middle of the bracket body 2 along the guide rail 8 after being pushed by the spring 7, and after the vertical plate 12 of the fixing piece 1 is contacted with the projector, the projector blocks the fixing piece 1 from continuing to move; at this time, the vertical plate 12 transmits the acting force of the spring 7 to the projector, so that the clamping force of the fixing piece 1 on the projector is formed, and the projector is fixed. Then, the user adjusts the spherical hinges 3 at the upper and lower ends of the upright post 4 according to the required pitching angle of the projector and the gravity center condition of the whole support, and after the state of the spherical hinges 3 is completed, the state of the spherical hinges 3 is locked through the locking mechanism 9 (the working principle of the locking mechanism 9 is the same as that of the locking mechanism 42), so that the adjustment and installation of the whole support are completed. When the support is dismantled, firstly, manually promote mounting 1 along the edge motion of guide rail 8 to support body 2, when riser 12 not with the projecting apparatus contact the back, take out the projecting apparatus, then relax mounting 1, mounting 1 replies support body 2 middle parts under the effect of spring, the dismantlement of completion projecting apparatus. Then the support 6 (namely the vacuum chuck) adsorbed on the ground is removed, then the two locking mechanisms 42 on the two lower upright post sections 41 are released, the elongation of each upright post section 42 is compressed to the minimum, the contraction of the upright post 4 is completed, and finally whether the locking structure 9 of the upper spherical hinge 3 and the lower spherical hinge 3 is released or not is determined according to the situation, so that the disassembly and the integral storage of the support are completed.

Example 2:

as shown in fig. 8 ~ 10, the difference between this embodiment and embodiment 1 is that the fixing member 1 adopts a suction cup manner, the structure is shown in fig. 9, and includes a positioning suction cup 14 and an i-shaped guide member 15, and the spring 7 and the guide rail 8 are eliminated, the structure is simpler, 4 of the embodiments are arranged on the bracket body 2 as shown in fig. 9, and the i-shaped guide member is clamped in the sliding groove 22 as shown in fig. 10 and can move along the sliding groove 22, so as to realize the position movement of the fixing member 1.

The specific working principle is as follows: the working principle of this embodiment is basically the same as that of embodiment 1, except for the fixing manner of the fixing member 1 and the projector. In use, a user manually adjusts the position of the fixing member 1 along the sliding groove 22, and then the positioning suction cups 14 of the fixing member 1 are used for sucking the projector to fix the projector. The sucker is fixed more simply and more quickly compared with the fixing mode of the embodiment 1.

Example 3:

as shown in fig. 11 ~ 13, on the basis of embodiment 1, three kinds of expansion members are added, including an expansion plate 101 (fig. 11) having a geometric size of 30cm long × 30cm wide × 1cm high, a hook 102 (fig. 12) and a small tripod 103 (fig. 13), wherein the three kinds of expansion members are provided with a clip structure, and are detachably connected to the column 4 by means of a clip connection, and in other embodiments, the three kinds of expansion members can be detachably connected to the column 4 by means of other prior art such as a bolt connection, and after the expansion plate 101 is connected to the column 4, signal source equipment such as a notebook computer can be conveniently placed, so as to facilitate the use of the projector, and after the hook 102 is connected to the column 4, the bracket can be integrally hung on the ceiling of a use space when the projector is not conveniently placed on the ground and the space ceiling cannot use the support 6 (suction cup) in embodiment 1, so as to facilitate the installation of the bracket and the projector.

Example 4:

in this embodiment, on the basis of embodiment 1, the fixed connection between the guide plate 11 and the vertical plate 12 and the fixed connection between the vertical plate 12 and the horizontal plate 13 in the fixing member 1 are both hinged, so that the bracket can be conveniently stored, and on the other hand, when fixing some special-shaped projectors (such as a camera-shaped projector), the hinged horizontal plate 13 can be stored as required, so that the special-shaped projectors cannot be blocked.

The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the technical matters of the present invention all fall into the protection scope of the present invention to any simple modification and equivalent change of the above embodiments.
