[0038] The utility model is further described in detail below based on the accompanying drawings and embodiments. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figure 1 to Figure 3As shown, the present invention provides an easy-to-install desktop projection bracket, comprising an annular base 1 and a supporting beam 2, wherein a rotating support 4 is symmetrically arranged on the annular base 1, and rotating arms 3 are symmetrically arranged on both sides of the supporting beam 2, wherein the rotating arms 3 are hinged to the rotating support 4, and the supporting beam 2 can be swung to rotate the supporting beam 2 relative to the annular base 1 by an angle of 0° to 180°, thereby controlling the projection angle of the projector to bring about a better projection effect;

[0040] A locking screw hole 201 is provided at the axial position of the supporting beam 2, and the locking screw hole 201 matches the locking screw 5. The locking screw 5 is inserted from the bottom of the locking screw hole 201 to achieve a locking connection with the projector located on the surface of the supporting beam 2. It should be noted that before the projector leaves the factory, a projector fixing threaded hole will be preset at the bottom of the projector. The locking screw 5 in this embodiment can be locked with the projector fixing threaded hole, thereby achieving the purpose of fixing the projector to the surface of the beam.

[0041] In this embodiment, the support beam 2 is connected to the rotating arm 3 at an angle of 90° to 150°.

[0042] like Figure 4 and Figure 5 As shown, in order to prevent the locking screw 5 from falling due to its own gravity when not in use, this embodiment provides an annular limiting mechanism composed of a plurality of clamping feet 203 at the bottom opening of the locking screw hole 201. The inner diameter of the inner ring of the annular limiting mechanism is smaller than the outer diameter of the head of the locking screw, so that the locking screw 5 can be confined in the locking screw hole 201.

[0043] like Figure 3 As shown, the annular base 1 in this embodiment includes a first base 101 and a second base 102 that can be snapped together.

[0044] As a specific embodiment of the present solution, the first base 101 and the second base 102 are symmetrically arranged about the central axis of the annular base 1 .

[0045] Male buckle mechanisms 103 extending outward are provided at both ends of the first base 101, and correspondingly, female buckle mechanisms 104 matching the male buckle mechanisms 103 are provided at both ends of the second base 102; by the mutual snapping of the male buckle mechanism 103 and the female buckle mechanism 104, the first base 101 and the second base 102 can be quickly assembled into a ring.

[0046] like Figure 6 and Figure 7 As shown, the male buckle mechanism 103 in this embodiment includes a male buckle support 105 extending outward;

[0047] Correspondingly, the female buckle mechanism 104 includes a female buckle embedding groove 106 for the male buckle support 105 to embed;

[0048] By interlocking the male buckle support 105 and the female buckle groove 106, the first base 101 and the second base 102 can be quickly assembled into a ring shape.

[0049] A male buckle plug post 107 is provided on the male buckle support 105 , and correspondingly, a female buckle plug hole 108 for inserting the male buckle plug post 107 is provided on the top wall of the female buckle embedding groove 106 .

[0050] This structure can not only realize the quick assembly of the first base 101 and the second base 102 into a ring, but also prevent the left and right separation of the two.

[0051] like Figure 6 and Figure 7 As shown, it should be noted that, under the limitation of this structure, the assembly method of the first base 101 and the second base 102 in this embodiment is upper and lower snap-on, that is, the first base 101 is placed outside below the second base 102, and then the male buckle pin 107 and the female buckle socket 108 are plugged up and down, thereby achieving the purpose of quick assembly.

[0052] As a specific embodiment of the present solution, in this embodiment, two male buckle posts 107 are provided on the male buckle support 105 , and correspondingly, two female buckle holes 108 are provided in the female buckle groove 106 .

[0053] In this embodiment, in order to prevent the first base 101 and the second base 102 from being separated from each other during the assembly process after the upper and lower buckles are snapped in, a deformation seam 110 is opened on the surface of the male buckle column 107. The deformation seam 110 can ensure that the male buckle column 107 has a slight inward deformation due to interference, and then can be tightly connected with the female buckle socket 108.

[0054] In this embodiment, the two rotating supports 4 are respectively disposed on the first base 101 and the second base 102 , and are symmetrically disposed about the central axis of the annular base 1 .

[0055] In this embodiment, the rotating seat 4 is U-shaped, and the middle is used for inserting the rotating arm 3. The rotating seat 4 and the rotating arm 3 are both provided with corresponding screw holes 7, and the two are hinged by screws 8 and nuts 9.

[0056] As an optimization of this solution, the surface of the supporting beam 2 is provided with a plurality of raised ribs 202 symmetrically about the locking screw hole 201, which are used to first contact with the bottom wall of the projector when the projector is installed, and can provide a certain deformation tension of about 0.5 mm for the connection between the locking screw 5 and the projector, thereby effectively preventing the locking screw 5 and the projector from loosening.

[0057] like Figure 2 and Figure 6 As shown, as a further optimization of this embodiment, the present solution further provides a plurality of gasket grooves 109 on the bottom wall of the annular base 1 for the silicone gasket 6 to be embedded in. After installation, the silicone gasket 6 slightly extends out of the gasket groove 109 so as to contact with the desktop, thereby providing a non-slip protection for the annular base 1.

[0058] The above description is only for illustrating the implementation mode of the present invention and is not intended to limit the present invention. For those skilled in the art, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
