Description

Technical Field

[0001] This utility model relates to the field of audio equipment accessories technology, and in particular to a universal audio equipment hoisting device. Background Technology

[0002] In professional sound reinforcement venues such as large concerts, stadiums, theaters, and conference centers, in order to achieve uniform sound coverage and precise sound directionality, it is necessary to suspend individual or group speaker enclosures in the air. Speaker hoisting devices used to achieve this purpose are key equipment to ensure the safe and efficient deployment of sound systems.

[0003] Existing speaker hoisting devices can, in their basic functions, fix and support the speaker enclosure. The basic hoisting components are connected by multiple bolts at the screw holes reserved in the speaker enclosure. Although this method is reliable, it requires tightening multiple bolts one by one during on-site installation, which is a cumbersome process and results in low installation and disassembly efficiency.

[0004] To improve installation efficiency, hoisting devices with quick-clamping functions use lever or screw-driven clamping arms to clamp the speaker enclosures. Compared to pure bolt connections, this simplifies the operation to some extent. However, the design focus of these hoisting devices is only on how to achieve clamping, while neglecting the equally crucial "angle adjustment" function in speaker hoisting applications. In practical applications, the pitch angle of the speakers directly determines the sound projection area and needs to be precisely set according to factors such as the size of the venue and the location of the audience area. Existing devices either lack or only have structurally separate and complex angle adjustment functions, forcing on-site personnel to use other auxiliary tools or perform secondary complex operations to adjust the angle after clamping. This not only reduces work efficiency but also increases the difficulty and risk of working at height.

[0005] Therefore, this utility model proposes a universal speaker hoisting device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of cumbersome clamping structure operation and lack of convenient angle adjustment function integrated with the main body in the existing general-purpose speaker hoisting device, resulting in insufficient adaptability to various scenarios, this utility model aims to provide a general-purpose speaker hoisting device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a universal speaker hoisting device, including a support leg and a connecting plate fixedly connected to the support leg; the universal speaker hoisting device also includes a hoisting rod, a second fixing block, a support plate, a clamping plate, a first fixing block, a first rotating column, a second rotating column, and an angle adjustment mechanism.

[0008] The general-purpose audio equipment hoisting device achieves clamping function through a precise linkage mechanism. The hoisting rod can slide in the vertical direction. The second fixing block is fixedly connected to the lower end of the hoisting rod. One end of the support plate is rotatably connected to the support leg, while the clamping plate is fixedly connected to the end of the support plate away from the support leg.

[0009] Furthermore, the first fixed block is fixedly connected to the connecting plate; the first rotating column is rotatably connected between the first fixed block and the support leg; the two ends of the second rotating column are respectively rotatably connected to the second fixed block and the support plate, together forming a linkage mechanism that efficiently converts the linear motion of the hoisting rod into the synchronous centripetal clamping action of the clamping plate. At the same time, the angle adjustment mechanism is fixedly connected to the connecting plate. The mechanism includes a fixed plate and a push rod that can slide and lock on the fixed plate, which is used to collaboratively set the pitch angle of the speaker.

[0010] Preferably, the universal audio jacking device further includes a connecting shell, which is fixed to the connecting plate, and the jacking rod slides through the interior of the connecting shell, providing stable guidance for the sliding of the jacking rod and ensuring smooth movement and verticality when bearing load.

[0011] Preferably, the general-purpose speaker hoisting device further includes a rotating column three, which is rotatably connected between the support plate and the clamping plate. This rotating column three is used to fine-tune the posture of the clamping plate during the clamping process, so as to better fit the sides of speaker cabinets of different shapes or with curvature, thereby increasing the effective contact area and improving the friction and stability of the clamping.

[0012] Preferably, the fixed plate of the angle adjustment mechanism is provided with a slide rail extending in the horizontal direction, and the push rod is installed in the slide rail by sliding engagement. This track-type engagement method ensures that the push rod can perform smooth and precise linear movement when adjusting the angle.

[0013] Preferably, based on the above, one end of the push rod is fixedly connected to a push plate, the surface of the push plate is perpendicular to the sliding direction of the push rod, and the push plate is designed to form a large, flat force-bearing surface for abutting the speaker surface, so as to apply force evenly when adjusting the angle and effectively avoid indentation or damage to the speaker cabinet due to excessive local pressure.

[0014] Preferably, in order to achieve multi-level, repeatable, and precise angle locking, the fixed plate is provided with multiple limiting grooves arranged at intervals along the length of the slide rail, and the push rod is provided with a corresponding locking groove. This multi-groove structure provides a physical basis for the stepped adjustment of the angle, making it easy for users to quickly select and reproduce the preset angle.

[0015] Preferably, the angle adjustment mechanism further includes a bolt and a fixing nut that is threaded with the bolt. When the angle is adjusted to the correct position, the bolt can pass through the selected limiting groove and the locking groove in sequence. Then, by tightening the fixing nut, the push rod can be reliably locked in the current position using a strong axial clamping force.

[0016] Preferably, to ensure the stability of the overall structure and the balance of forces, the outriggers, support plates, clamping plates, rotating column one and rotating column two are all set in two groups and are symmetrically arranged with the central vertical plane of the hoisting rod as the reference. This completely symmetrical layout effectively counteracts various deflection moments that may be generated during hoisting and clamping, ensuring the stability of the device's posture.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting up a mechanical linkage clamping mechanism composed of components such as lifting rods, fixing blocks, rotating columns and support plates, transforms a single upward lifting action into a symmetrical centripetal clamping force, thus solving the problem of cumbersome clamping operation and reliance on multiple manual locking points in some existing lifting devices.

[0019] 2. This utility model solves the problem of existing hoisting devices having limited functionality and being unable to conveniently preset the pitch angle before hoisting by integrating an angle adjustment mechanism consisting of a fixed plate, slide rail, push rod, push plate, and multi-position locking groove.

[0020] 3. This utility model solves the problem in the prior art that may require additional components or complex adjustments to achieve clamping and angle adjustment simultaneously by integrating the clamping mechanism and the angle adjustment mechanism on a unified frame composed of support legs and connecting plates.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 4 This utility model provides a universal speaker hoisting device, which aims to solve the problems of cumbersome operation of the clamping structure of existing speaker hoisting devices, difficulty in controlling the clamping force, and lack of angle adjustment function integrated with the main body, resulting in insufficient adaptability to various scenarios.

[0030] like Figure 1 As shown, the general-purpose audio equipment includes a support leg 1 and a connecting plate 3 for connecting the support leg 1. The connecting plate 3 is arranged horizontally and fixedly connected to the upper part of the support leg 1, providing a basic platform for the installation of other components. The general-purpose audio equipment also includes a lifting rod 5, which can slide in the vertical direction to bear the lifting load and drive the clamping mechanism.

[0031] like Figure 1 and Figure 3 As shown, the general-purpose audio hoisting device also includes a fixing block 8, a support plate 10, and a clamping plate 12. The fixing block 8 is fixedly connected to the lower end of the hoisting rod 5. One end of the support plate 10 is rotatably connected to the support leg 1. The support plate 10 is used to transmit clamping force. The clamping plate 12 is fixedly connected to the end of the support plate 10 away from the support leg 1. The inner side of the clamping plate 12 is used to directly attach to and clamp the audio cabinet.

[0032] like Figure 1 and Figure 2As shown, the general-purpose audio equipment hoisting device also includes a fixed block 6, a rotating column 7, a rotating column 9, and an angle adjustment mechanism 2. The fixed block 6 is fixedly connected to the connecting plate 3. The rotating column 7 is rotatably connected to the fixed block 6 and the support leg 1, and is used to guide the movement trajectory of the support leg 1 during the clamping action. The two ends of the rotating column 9 are rotatably connected to the fixed block 8 and the support plate 10, respectively, which can convert the vertical movement of the hoisting rod 5 into the rotation of the support plate 10. The angle adjustment mechanism 2 is fixedly connected to the connecting plate 3 and includes a fixed plate 201 and a push rod 204 that can slide and lock on the fixed plate 201, and is used to set the pitch angle of the audio equipment before hoisting.

[0033] Please refer to Figures 1 to 3 When the hoisting rod 5 is lifted upwards or bears the weight of the speaker, the fixing block 8 will move upwards synchronously, pulling the support plate 10 through the rotating column 9 connected to both ends; the support plate 10 rotates with the rotating connection point with the support leg 1 as the fulcrum, driving the clamping plate 12 fixed to the other end to move inwards; at the same time, the fixing block 6 fixed to the connecting plate 3 is connected to the support leg 1 through the rotating column 7, which plays a role in guiding and stabilizing the posture of the support leg 1 during the whole movement, ensuring that the entire frame moves in concert when under force, and finally the clamping plate 12 clamps the speaker from both sides.

[0034] The general-purpose audio equipment also includes a rotating column 311, which is rotatably connected between the support plate 10 and the clamping plate 12. It is used to finely adjust the posture of the clamping plate 12 during the clamping process, so that the clamping plate 12 can better fit the sides of different audio equipment, increasing the contact area and friction.

[0035] The general-purpose audio equipment also includes a connecting shell 4, which is fixed to the connecting plate 3. The hoisting rod 5 slides through the inside of the connecting shell 4, providing precise guidance for the sliding of the hoisting rod 5 and ensuring the smoothness and verticality of the movement.

[0036] As a preferred embodiment, please refer to Figure 1 and Figure 4 In order to achieve precise adjustment and reliable locking of the pitch angle of the speaker, a slide rail 202 extending in the horizontal direction is provided on the fixed plate 201 of the angle adjustment mechanism 2. The push rod 204 is installed in the slide rail 202 by sliding fit, which ensures the stability and straightness of the movement of the push rod 204.

[0037] In a preferred embodiment, a push plate 205 is fixedly connected to one end of the push rod 204; the surface of the push plate 205 is perpendicular to the sliding direction of the push rod 204, and the push plate 205 is used to form a large contact surface to abut against the surface of the speaker, so that when the speaker is pushed to adjust the angle, force can be applied evenly, avoiding damage to the speaker cabinet caused by excessive local pressure.

[0038] In a preferred embodiment, in order to achieve multi-position, repeatable, and precise angle locking, the fixing plate 201 is provided with multiple limiting grooves 203 arranged at intervals along the length of the slide rail 202; and the push rod 204 is provided with a corresponding locking groove 206.

[0039] In a preferred embodiment, the angle adjustment mechanism 2 further includes a bolt 207 and a fixing nut 208 that is threadedly engaged with the bolt 207. When the push rod 204 slides to the predetermined position and the locking groove 206 is aligned with the target limiting groove 203, the bolt 207 can pass through the limiting groove 203 and the locking groove 206 in sequence. Then, by tightening the fixing nut 208, the push rod 204 can be firmly locked onto the fixing plate 201 by the axial clamping force of the bolt, thereby fixing the pitch angle of the sound.

[0040] Working principle: Before hoisting the speaker, the angle is first adjusted. The operator loosens the fixing nut 208 and bolt 207, allowing the push rod 204 to slide freely within the slide rail 202 of the fixing plate 201. By moving the push rod 204 back and forth, the push plate 205 pushes the speaker to rotate around the center of gravity or suspension point until the expected pitch angle is reached. After the angle is determined, the locking groove 206 on the push rod 204 is aligned with the corresponding limiting groove 203 on the fixing plate 201, the bolt 207 is inserted and tightened with the fixing nut 208, thereby firmly locking the push rod 204 and completing the preset angle.

[0041] The two clamping plates 12 of the device are respectively attached to both sides of the speaker; the lifting rod 5 is lifted upward or an upward pulling force is applied using the lifting equipment, and the lifting rod 5 drives the fixed block 8, which is fixedly connected, to move upward; the fixed block 8 pulls the support plate 10 through the rotating column 9, and the support plate 10 rotates about the connection point with the support leg 1; this causes the clamping plate 12 fixed on the support plate 10 to tighten inward, applying a clamping force to the speaker; at the same time, the support leg 1, guided by the rotating column 7, performs a small-amplitude inward rotation, which enhances the stability of the overall structure and the clamping effect; the entire linkage process smoothly converts the vertical pulling force of the lifting rod 5 into a symmetrical horizontal clamping force, realizing the rapid and stable clamping of the speaker.
