[0024] like Figure 1 to Figure 2As shown, a projector mounting structure with adjustable reflection angle includes a mounting frame 1, which is used to mount a projector 2;

[0025] The flip cover 3 is rotatably arranged on the mounting frame 1, and a reflecting portion 31 is provided on the flip cover 3. The reflecting portion 31 is used to reflect the projection light emitted by the projector 2 and change the focusing distance of the projector 2, so that: when the flip cover 3 drives the reflecting portion 31 to rotate, the projection light projected by the projector 2 is reflected to different angles via the rotating reflecting portion 31.

[0026] The projector installation structure with adjustable reflection angle of the present solution can solve the limitations existing after the traditional projector 2 is installed. The installation structure has the characteristics of being more flexible and safer, and can meet the growing needs of users.

[0027] Specifically, after the projector 2 is fixed on the mounting frame 1, the lens of the projector 2 can be kept in a stable state. Since the flip cover 3 is rotatably set on the mounting frame 1, when the rotation angle of the flip cover 3 changes, the angle of the reflecting part 31 set under the flip cover 3 also changes accordingly, so that the focusing distance between the projector 2 and the reflecting part 31 during projection (the focusing distance refers to the distance between the projector 2 and the reflecting part 31, that is, the distance between the lens and the object, excluding the distance between the lens and the photosensitivity) changes, so that the presented picture / image changes, which solves the problem of a single projection scene. The installation structure of multiple projectors 2 of this solution can be changed into different projection images, which meets the personalized requirements of users and greatly improves the audience's viewing experience.

[0028] Furthermore, the flip cover 3 is rotatably arranged on the front side of the mounting frame 1 through a plurality of hinges 32, a first telescopic assembly 33 is respectively connected to one side of the flip cover 3 and one side of the mounting frame 1, a second telescopic assembly 34 is respectively connected to the other side of the flip cover 3 and the other side of the mounting frame 1, and the first telescopic assembly 33 and the second telescopic assembly 34 are used to synchronously extend or shorten to drive the flip cover 3 to rotate to different angles.

[0029] One side of the flip cover 3 is rotatably arranged in front of the mounting frame 1 through at least two hinges 32. The projection direction of the projector 2 is opposite to the reflecting part 31 on the flip cover 3. The adjustment of the flip angle is achieved by the first telescopic component 33 and the second telescopic component 34. The first telescopic component 33 and the second telescopic component 34 connect the two sides of the mounting frame 1 and the flip cover 3. Since the first telescopic component 33 and the second telescopic component 34 can be extended or shortened synchronously, the movement trends of the two are consistent, so that the user can more conveniently adjust the distance between the flip cover 3 and the projector 2.

[0030] Furthermore, the first telescopic component 33 and the second telescopic component 34 each include a connecting body 331, two fixing columns 332 and two joints 333, the ends of the two joints 333 are provided with screws 334, both ends of the connecting body 331 are provided with connecting holes with internal threads, the interior of the connecting body 331 is through-set, the two screws 334 of the two joints 333 are respectively threadedly connected to the connecting holes and extend into the connecting body 331, and the two joints 333 are respectively connected to the flip cover 3 and the mounting frame 1 through the two fixing columns 332.

[0031] The first telescopic assembly 33 and the second telescopic assembly 34 have the same structure, and both can be UU-type open rigging turnbuckles, which specifically include a connecting body 331, a fixing column 332, and a joint 333. When the user needs to adjust the distance, he or she twists the screw rod 334 to make the screw rod 334 move along the connecting hole, and drives the joint 333 connected to the screw rod 334 to change position, so as to adjust the distance between the flip cover 3 and the projector 2.

[0032] In this embodiment, the end connected to the mounting frame 1 is also provided with a joint 333 with a screw rod 334, which can further expand the adjustable range of the flip cover 3.

[0033] Furthermore, a fixed frame 11 is provided in the mounting frame 1, and the projector 2 is installed at the lower end of the fixed frame 11;

[0034] The fixing frame 11 includes a first connecting rod 111 and a second connecting rod 112 . The first connecting rod 111 and the second connecting rod 112 are arranged in parallel and spaced apart. Both ends of the first connecting rod 111 and the second connecting rod 112 are connected by two third connecting rods 113 , respectively.

[0035] like Figure 2 As shown, the projector 2 is installed below the fixed frame 11 by screws. The fixed frame 11 is assembled by a first connecting rod 111, a second connecting rod 112 and two third connecting rods 113, and has high strength, which can meet the fixing requirements of the projector 2. Of course, in this embodiment, another third connecting rod 113 can be set in the middle of the first connecting rod 111 and the second connecting rod 112. In this way, four third connecting rods 113 are set at intervals between the first connecting rod 111 and the second connecting rod 112, and the installation strength of the fixed frame 11 is high. At the same time, the user can also choose to install and fix the projector 2 on any of the third connecting rods 113 according to needs.

[0036] Furthermore, two sliding grooves 114 are provided on the two third connecting rods 113, and the sliding grooves 114 are used for the first connecting column 115 or the second connecting column 116 to move. The first connecting column 115 passes through one of the sliding grooves 114 to connect the third connecting rod 113 and the first connecting rod 111, and the second connecting column 116 passes through the other sliding groove 114 to connect the third connecting rod 113 and the second connecting rod 112.

[0037] Since different projectors 2 have different specifications and sizes, in order to meet the installation needs of more types of projectors 2, this solution provides a slide groove 114 on the third connecting rod 113, and a first connecting column 115 or a second connecting column 116 (both of which can be screws) is installed in the slide groove 114. The first connecting column 115 connects the first connecting rod 111 and the third connecting rod 113, and the second connecting column 116 connects the second connecting rod 112 and the third connecting rod 113. By installing the first connecting column 115 and the second connecting column 116 at different positions of the slide groove 114, the distance between the first connecting rod 111 and the second connecting rod 112 can be lengthened or shortened to accommodate the installation of more types of projectors 2.

[0038] Furthermore, the mounting frame 1 is formed by a first side 12 , a second side 13 , a third side 14 and a fourth side 15 connected in sequence, and a mounting plate 17 with an opening 16 is provided in the mounting frame 1 , and the fixing frame 11 is arranged below the mounting plate 17 .

[0039] The first side 12, the second side 13, the third side 14 and the fourth side 15 are arranged to form a hollow quadrilateral mounting frame 1. A mounting plate 17 is provided at the bottom of the mounting frame 1. A relatively large opening 16 is provided on the mounting plate 17, which can save raw material and production costs and reduce the weight of the mounting frame 1. The fixing frame 11 is fixed to the lower end of the mounting plate 17 by means of the first connecting column 115 and the second connecting column 116, and the projector 2 is fixed to the lower end of the mounting frame by means of screws.

[0040] Furthermore, the top ends of the first side 12 and the third side 14 extend horizontally outward to form an edge 18, and a plurality of mounting grooves 181 for mounting bolts are provided on the edge 18 to fix the mounting frame 1 to the external structure. The mounting frame 1 is provided with an edge 18, and the edge 18 is fixed to the external structure by bolts. The bolts are arranged in the waist-shaped mounting groove 181, and can also be fixed at different positions in the mounting groove 181, which makes it easier to fix the mounting frame 1 to different external structures.

[0041] Furthermore, the two sides of the reflective portion 31 are detachably arranged at the lower end of the flip cover 3 through the pressing piece 35. The reflective portion 31 is installed below the flip cover 3 through the glass pressing piece 35, which is convenient for disassembly and replacement.

[0042] Furthermore, the reflecting portion 31 is a reflecting glass. The reflecting glass can better reflect the image projected by the projector 2. Of course, in other embodiments, the reflecting portion 31 can also be a reflecting mirror.

[0043] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
