Description

Technical Field

[0001] This utility model relates to the field of audio installation technology, specifically to an audio equipment mounting device. Background Technology

[0002] Audio equipment is an important component of audio playback systems, widely used in various venues such as conference rooms, concert halls, large stadiums, and homes. It typically includes the speaker enclosure, related circuit modules for audio signal processing, and sound-generating units. It converts electrical signals into sound wave signals to amplify and propagate sound, meeting the sound reinforcement needs of different environments.

[0003] In practical applications, to achieve better sound coverage, audio equipment often needs to be installed in high locations such as ceilings or rooftops. In this case, a connecting device is typically installed on the top wall of the audio equipment, which then connects to the ceiling for a secure connection. Most of these connecting devices on the market now feature angle adjustment capabilities. Since the tilt angle of the audio equipment directly affects the direction and coverage of sound propagation, different tilt angles result in different listening experiences; therefore, the accuracy and ease of angle adjustment are particularly important.

[0004] However, existing connection devices often require operators to climb above the audio equipment using ladders or other tools when adjusting the angle. During the adjustment process, the speaker must be manually supported to bear its weight before being fixed in place. This adjustment method is cumbersome, labor-intensive, and poses certain inconveniences and safety hazards when working at heights, making it unsuitable for efficiently and conveniently adjusting the angle of audio equipment.

[0005] Furthermore, existing connection devices mostly achieve angle adjustment through the cooperation of pins and slots. When the device is tilted to a specific angle, the slot must be aligned and the pin inserted to fix the tilt angle. This adjustment method can only adjust the angle at a few positions and cannot achieve stepless adjustment, resulting in insufficient precision in adjusting the tilt angle of the audio equipment, making it difficult to meet the refined sound effect requirements in different scenarios. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides a sound equipment mounting device that solves the problems of existing sound equipment mounting devices requiring high-altitude operations for angle adjustment, being cumbersome to operate, and lacking stepless adjustment, resulting in inaccurate angles.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sound equipment mounting device, including a mounting frame, a rotatable mounting plate hinged to the bottom of the mounting frame, the mounting plate for mounting the sound unit, a rotatable first connecting member mounted on the mounting plate, and a rotatable second connecting member mounted on the mounting frame. The rotation axis directions of the first connecting member, the second connecting member, the mounting plate, and the mounting frame at their hinged positions are the same. The first connecting member and the second connecting member are connected to the same lead screw, the end of which passes through the first connecting member and is located below the mounting plate. By rotating the lead screw, the distance between the first connecting member and the second connecting member can be adjusted, thereby causing the mounting plate to rotate at the hinged position, and thus adjusting the tilt angle of the sound unit mounted on the mounting plate.

[0008] Compared with the prior art, the present invention provides a device for mounting audio equipment, which has the following advantages: This audio equipment mounting device has a mounting plate hinged to the bottom of the mounting frame. With the connection of the first connector, the second connector and the screw, the tilt angle of the mounting plate and the audio body can be adjusted by rotating the screw.

[0009] The end of the lead screw passes through the first connector and is located below the mounting plate, allowing operators to adjust the tilt angle of the speaker from below. During operation, extended wrenches, socket wrenches, and other compatible tools can be used to tighten the lead screw. This method not only reduces the safety risks associated with working at heights but also simplifies the adjustment process, making angle adjustment more convenient and efficient.

[0010] Due to its lead screw threaded joint structure, by rotating the lead screw and utilizing the continuity and precision of the threaded transmission, the distance between the first and second connecting parts can be precisely controlled by adjusting the rotation angle of the lead screw, thereby achieving stepless adjustment of the tilt angle of the mounting plate and the speaker body. Compared to the multi-position adjustment method using traditional pins and slots, this adjustment method has no limitation on the interval between positions. It can precisely adjust the tilt angle of the speaker body to any desired position according to actual needs, greatly improving adjustment accuracy and better meeting the refined requirements for sound effect coverage, directivity, etc., in different scenarios.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-2 The present invention relates to an audio equipment mounting device, comprising a mounting frame 1, and a mounting plate 2 that can rotate at a hinged position at the bottom of the mounting frame 1. The main purpose of the mounting plate 2 is to mount and fix the audio unit 3, ensuring that the audio unit 3 is stable on the mounting plate 2 during use. To enable the mounting plate 2 to rotate relative to the mounting frame 1, the bottom of the mounting frame 1 and one side of the mounting plate 2 are connected by a hinge. Specifically, the hinge assembly can be completed by a hinge 21, a pivot, a hinge, or other device. With the help of the hinge device, the mounting plate 2 can rotate flexibly around the hinged position, thereby enabling subsequent adjustment of the tilt angle of the audio unit 3.

[0015] like Figure 1-4 As shown, a rotatable first connector 4 is mounted on the mounting plate 2, and the first connector 4 is rotatably fitted with the mounting plate 2; correspondingly, a rotatable second connector 5 is also mounted on the mounting bracket 1.

[0016] It should be noted that the rotation axis directions of the first connector 4 and the second connector 5 are consistent with the rotation axis direction of the hinge position between the mounting plate 2 and the mounting bracket 1. The consistency of the rotation axis directions among the above three components can avoid interference problems during the movement of the components.

[0017] A lead screw 6 is connected to both the first connector 4 and the second connector 5. The lead screw 6 and the two connectors form a suitable transmission relationship. The bottom end of the lead screw 6 passes through the first connector 4 and extends to the area below the mounting plate 2, providing convenient space for rotating the lead screw 6. The angle of the speaker body 3 can be adjusted from below the speaker body 3.

[0018] When it is necessary to adjust the tilt angle of the speaker body 3, the operator can turn the end of the lead screw 6 located below the mounting plate 2. As the lead screw 6 rotates, it will change the distance between the first connecting piece 4 and the second connecting piece 5 through the transmission cooperation with the first connecting piece 4 and the second connecting piece 5. Since the mounting plate 2 and the mounting bracket 1 are hinged, the change in distance will cause the mounting plate 2 to rotate around the hinge position as the rotation center, thereby causing the speaker body 3 mounted on the mounting plate 2 to adjust the tilt angle synchronously, so as to achieve precise adjustment of the tilt angle of the speaker body 3.

[0019] The lead screw 6 can be connected to the first connecting member 4 and the second connecting member 5 in three ways. Each of these different connection methods can achieve the function of adjusting the distance between the first connecting member 4 and the second connecting member 5 when the lead screw 6 is rotated. Specific details are as follows: In the first connection method, such as Figure 1-4 As shown, the lead screw 6 and the first connecting member 4 are rotatably connected, meaning the lead screw 6 can rotate freely relative to the first connecting member 4 without axial displacement. The lead screw 6 and the second connecting member 5 are connected via a threaded engagement, forming a threaded pair. Simultaneously, the top end of the lead screw 6 extends upward through the second connecting member 5, and a limiting block 8 is fixedly installed at the top end of the lead screw 6. The size of the limiting block 8 is larger than the size of the threaded engagement hole between the lead screw 6 and the second connecting member 5, effectively preventing the lead screw 6 from disengaging from the second connecting member 5 during adjustment and ensuring connection stability. The bottom end of the lead screw 6 extends downward through the first connecting member 4, and a screwing part is provided at the bottom end of the lead screw 6. This screwing part allows operators to easily screw the lead screw 6 using tools or by hand, providing convenience for operation.

[0020] The second connection method is that the lead screw 6 and the second connecting member 5 are rotated together, and the lead screw 6 can rotate flexibly relative to the second connecting member 5 without axial movement; the lead screw 6 and the first connecting member 4 are connected by threads to form a threaded pair, and the bottom end of the lead screw 6 passes through the first connecting member 4 downwards, and a screwing part is provided at the bottom end of the lead screw 6. This screwing part makes it easy for the operator to screw the lead screw 6 with tools or directly by hand, which provides convenience for operation.

[0021] The third connection method uses a bidirectional lead screw 6, meaning it has two external threads with opposite directions of rotation. One side of the lead screw 6 is threaded to the first connecting member 4, and the other side is threaded to the second connecting member 5. Each thread matches the internal thread of its corresponding connecting member. When the bidirectional lead screw 6 is rotated, the first connecting member 4 and the second connecting member 5 move in opposite directions along the axial direction of the lead screw 6 due to the opposite rotation directions, thus adjusting the distance between them. A limit block 8 is fixed at the top of the lead screw 6. The size of the limit block 8 is larger than the threaded mating hole between the lead screw 6 and the second connecting member 5, effectively preventing the lead screw 6 from disengaging from the second connecting member 5 during adjustment and ensuring connection stability. The bottom end of the lead screw 6 extends downward through the first connecting member 4 and has a screw-tightening part. This part allows operators to easily screw the lead screw 6 using tools or by hand, providing convenience for operation.

[0022] In practical use, the preferred connection method is the first type (i.e., the lead screw 6 is rotatably connected to the first connecting part 4 and threadedly connected to the second connecting part 5). Figure 1-4 As shown, when this connection method is used, when the mounting plate 2 is rotated around the hinge position (e.g., rotated upwards), since the lead screw 6 and the first connecting member 4 are rotatably connected, the lead screw 6 will move synchronously with the movement of the mounting plate 2. Specifically, when the mounting plate 2 is rotated upwards, the lead screw 6 will move upwards along with it, thus avoiding excess exposed length of the lead screw 6 below the mounting plate 2. This follow-up characteristic can effectively save space below the mounting plate 2 and reduce the space occupied by the lead screw 6 in the lower operating space.

[0023] A through slot 26 is provided on the mounting plate 2. The through slot 26 is mainly used to install the first connecting member 4, and also provides space for the lead screw 6 to pass through the mounting plate 2, ensuring that the lead screw 6 can pass through the mounting plate 2 and extend below it.

[0024] The screw-in section installed at the bottom of the lead screw 6 can be configured in various ways to meet different operational needs: it can be a polygonal screw block 7, similar in shape to a nut head or nut, suitable for use with tools such as wrenches; it can be a rotary handle for easy hand operation; or it can be a crossbar perpendicular to the axis of the lead screw 6. This diverse structural design allows operators to rotate the knob directly by hand or use tools such as wrenches, improving ease of operation and adapting to different adjustment scenarios.

[0025] In this way, when adjusting the tilt angle of the speaker body 3, the staff does not need to climb to a high place (that is, operate from above the speaker body 3). They can operate from below the mounting bracket 1. They can use appropriate tools such as extended wrenches or socket wrenches to turn the screw 6 located below the mounting plate 2. The force transmitted by the tool drives the screw 6 to rotate, and then, through the cooperation between the screw 6 and the first connecting piece 4 and the second connecting piece 5, the tilt angle of the mounting plate 2 and the speaker body 3 can be adjusted. This operation method eliminates the need for working at height, which is convenient for adjustment and improves the safety of the operation process.

[0026] like Figure 1-2 As shown, there are two ways to install mounting bracket 1: The first type involves a suspension bracket above the mounting frame 1, comprising a connecting plate 13, a mounting shaft 14, and a mounting base 15. The connecting plate 13 is detachably connected to the mounting frame 1. The mounting base 15 is located above the connecting plate 13 and is used to connect to the ceiling. The mounting base 15 is connected to the mounting plate 2 via the mounting shaft 14, allowing the mounting plate 2 and mounting base 15 to rotate relative to each other. This rotation is subject to damping force, which can be achieved, for example, through damping washers or damping bearings. Using this method, the speaker can be adjusted not only for tilt but also for rotation. Simultaneously, the connecting plate 13 has a first mounting hole 16.

[0027] The second type has a mounting block 17 that can be detachably and fixedly mounted on the mounting bracket 1, and the mounting block 17 has a second mounting hole 18. In this method, the mounting bracket 1 can be directly mounted on the ceiling through the mounting block 17, but the rotation angle of the speaker cannot be adjusted.

[0028] The first mounting hole 16 and the second mounting hole 18 mentioned above are both used to insert expansion bolts and other devices to fix the mounting bracket 1.

[0029] like Figure 6 As shown, the audio equipment mounting device also includes a protective box 22, which is completely surrounded by the mounting frame 1. Its function is to protect the mounting frame 1 and the audio body 3 mounted on the mounting plate 2, thereby reducing the impact of external dust, minor collisions, etc. on the equipment components and ensuring the stable operation of the entire device.

[0030] To achieve the assembly of the protective box 22 and the mounting bracket 1, the protective box 22 and the mounting bracket 1 are detachably connected. The specific connection structure is as follows: several through holes 24 are provided on the protective box 22, and a bolt 23 is installed in each through hole 24; correspondingly, screw holes 25 are pre-set at positions on the mounting bracket 1 that correspond to the positions of the through holes 24, and the internal threads of the screw holes 25 are compatible with the external threads of the bolts 23. When it is necessary to install the protective box 22, simply align the through holes 24 on the protective box 22 with the screw holes 25 on the mounting bracket 1, then screw the bolts 23 into the screw holes 25 and tighten them to complete the fixation of the protective box 22 and the mounting bracket 1; if it is necessary to disassemble the protective box 22, loosen the bolts 23 in the opposite direction and remove it to separate the protective box 22 from the mounting bracket 1.

[0031] The second connector 5 is detachably connected to the mounting bracket 1. Under normal use, the second connector 5 remains connected to the mounting bracket 1, working with the first connector 4 and the lead screw 6 to adjust the tilt angle of the speaker body 3. When the speaker body 3 needs to be stored, the second connector 5 can be removed from the mounting bracket 1. At this time, there is no need to adjust the spacing by rotating the lead screw 6; the mounting plate 2 can be directly flipped towards the mounting bracket 1, so that the mounting plate 2 covers the bottom of the mounting bracket 1. This storage method eliminates the tedious steps of traditional step-by-step adjustment via the lead screw 6, making operation more convenient and effectively improving the efficiency of speaker storage.

[0032] Mounting bracket 1 has a detachable mounting component 9, which allows the second connecting component 5 to be disassembled. Figure 7 As shown, the mounting component 9 has a mounting groove 10 for mounting the second connector 5. The top of the mounting groove 10 has an opening 11 for the second connector to enter, allowing the second connector 5 to be directly removed from the mounting groove 10 for disassembly. The mounting groove 10 is bent to prevent the second connector 5 from accidentally coming out during adjustment. For added safety, a locking device, such as a pin or a spring-loaded stop, can be installed at the opening 11.

[0033] like Figure 8 As shown, the second connector 5 has a slot 12 for the side wall of the mounting piece 9 to be inserted into. After the side wall of the mounting piece 9 is inserted into the slot 12, the second connector 5 is prevented from moving.

[0034] like Figure 5As shown, a stop 19 is rotatably connected to the bottom of the mounting bracket 1 via a connecting shaft 20. The stop 19 does not move downwards along the axis of the connecting shaft 20. By rotating the stop 19, it can be rotated around the connecting shaft 20 to a first angle (below the mounting plate 2) to block the bottom wall of the mounting plate 2. The stop 19 can also be rotated around the connecting shaft 20 to a second angle (not below the mounting plate 2) to release the blockage on the bottom wall of the mounting plate 2. Other devices, such as latches or locks, can also be used to block the bottom of the mounting plate 2.

[0035] In summary, this audio equipment mounting device, when in use, has the mounting bracket 1 fixed to the ceiling. Workers, positioned below the speaker unit 3, use tools such as an extended wrench to rotate the screw 6, adjusting the tilt angle of the mounting plate 2 and the speaker unit 3 to the desired position. When storing the speaker unit 3, the second connecting piece 5 is removed, and the mounting plate 2 is flipped over to cover the bottom of the mounting bracket 1. The stop block 19 is rotated until it touches the bottom of the mounting plate 2 to prevent accidental opening. The protective box 22 is then connected to the mounting bracket 1 via bolts 23, enclosing the outside of the mounting bracket 1 and protecting both the mounting bracket 1 and the speaker unit 3, facilitating subsequent transportation and storage of the speaker unit 3.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
