DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the utility model belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0022] The embodiment of the utility model provides an audio and video equipment bracket structure, including a fixing part 1, an installation part 2 and a connecting part 3, the fixing part 1 is used to connect with a bearing object, and is provided with a plurality of waist-shaped through holes for easy fixation, wherein the bearing object can be a wall, a wall panel, a cabinet surface, etc., which is confirmed based on the installation environment required for the actual installation; the installation part 2 is connected to the fixing part 1 through a bolt structure, the connecting part 3 is hinged to the installation part 2, and a bearing part 4 for bearing the audio and video equipment is arranged on the connecting part 3, the connecting part 3 includes mutually cooperating limiting parts, and the gravity of the audio and video equipment on the bearing part 4 enables the mutually cooperating limiting parts to fix the connecting part 3 and the mounting part 2.

[0023] Specifically, the connecting portion 3 includes a connecting column 31, a rotating shaft 32, a fixed limiting piece 33 and a movable limiting piece 34. The mounting portion 2 is rotatably connected to a side of the mounting portion 2 away from the fixing portion 1. The rotating shaft 32 is connected to the connecting column 31. The connecting column 31 is connected to the bearing portion 4. The rotating shaft 32 is provided with a fixed limiting piece 33. The rotating shaft 32 is sleeved with a movable limiting piece 34 that cooperates with the fixed limiting piece 33. The movable limiting piece 34 engages with the fixed limiting piece 33 under the gravity of the audio and video equipment on the bearing portion 4, so that the mounting portion 2 and the rotating shaft 32 cannot form relative rotation, and the mounting portion 2 and the connecting portion 3 are fixed. The fixed limiting piece 33 and the movable limiting piece 34 are both annular, and a plurality of tooth structures are arranged at intervals along the circumferential direction on the side surface. The tooth structures of the fixed limiting piece 33 and the movable limiting piece 34 are arranged relatively to each other.

[0024] In fact, since the latching structure can be made very small and will not affect the stability of the structure, more precise angle adjustment can be achieved. The minimum angle adjustment achieved in this embodiment is 1°. Of course, it can also be customized according to actual needs. The fixed limit member 33 and the movable limit member 34 are latched together to limit the rotation of the connecting part 3. After separation, the connecting part 3 can rotate freely. The latching separation of the fixed limit member 33 and the movable limit member 34 is determined based on the gravity of the audio and video equipment on the bearing part 4. When adjustment is required, the audio and video equipment is pushed upward so that its gravity is not applied to the bearing part 4, and the two limit members can be separated.

[0025] In some embodiments, the mounting portion 2 is a combination of a telescopic inner rod 21 and an outer rod 22. The horizontal position of the audio and video equipment can be adjusted by telescopic sliding adjustment of the inner rod 21 and the outer rod 22. The outer rod 22 is connected to the fixing portion 1 through a bolt structure, and the inner rod 21 is hinged to the connecting portion 3 through a rotating shaft 32. The inner rod 21 is hinged with a fixing member 23, one end of the fixing member 23 is movably connected to a movable limiting member 34, and the other end contacts the inner wall of the outer rod 22. The contact surface between the fixing member 23 and the outer rod 22 is an inclined surface. When the movable limiting member 34 moves and engages with the fixed limiting member 33, the fixing member 23 is driven to rotate around the hinge point, so that the other end of the fixing member 23 abuts against the inner wall of the outer rod 22, thereby fixing the relative position of the inner rod 21 and the outer rod 22.

[0026] In some embodiments, a threaded hole is provided on the outer rod 22, and a locking member is connected to the inner thread of the threaded hole. The locking member passes through the threaded hole and abuts against the inner rod 21. The relative position of the inner rod 21 and the outer rod 22 is fixed by the locking member to ensure the stability of the overall structure.

[0027] In some embodiments, the bearing portion 4 includes a mounting seat 41 and a trigger assembly. The mounting seat 41 is used to support the audio and video assembly. The mounting seat 41 is slidably connected to the connecting column 31. The trigger assembly is disposed in the connecting column 31. The gravity of the audio and video assembly acts on the mounting seat 41, causing the mounting seat 41 to slide downward, thereby triggering the trigger assembly, so that the trigger assembly squeezes the movable limit member 34 until it engages with the fixed limit member 33.

[0028] Specifically, the trigger assembly includes a trigger rod 42 and an elastic member 43. The connecting column 31 is provided with a strip groove, and the trigger rod 42 passes through the strip groove and is slidably connected to the connecting column 31. The side of the trigger rod 42 close to the movable limit member 34 is an inclined surface, and an elastic member 43 is connected between the trigger rod 42 and the connecting column 31. The elastic member 43 is used to reset the trigger rod 42; when the audio and video equipment is installed on the mounting seat 41, the mounting seat 41 moves downward under the action of the gravity of the audio and video equipment, thereby squeezing the trigger rod 42, causing the trigger rod 42 to move downward, and the elastic member 43 is compressed. The inclined surface of the trigger rod 42 close to the movable limit member 34 contacts the movable limit member 34 and squeezes the movable limit member 34, causing it to move in the direction of the fixed limit member 33, thereby causing the movable limit member 34 to engage with the fixed limit member 33 to fix the connecting part 3.

[0029] In some embodiments, the mounting base 41 may be suspended. It is only necessary to ensure that the audio and video device is mounted on the mounting base 41 , and the gravity of the audio and video device will drive the mounting base 41 to move downward, thereby squeezing the trigger rod 42 .

[0030] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
