Stackable power amplifier box

Abstract

The utility model discloses a kind of stackable power amplifier boxes, and stable stacking is realized by the cooperative design of box body and connecting component. The both sides of box body are provided with through hole grooves, and the bottom side wall is provided with a notch, which is used for the preliminary positioning of the connecting component of the upper layer box body when stacking. The connecting component is composed of first, second and third retaining plates and a latch, wherein the first and third retaining plates are misaligned and stacked to form a retaining space, and the width thereof is matched with the second retaining plate. When stacking, the retaining space of the upper layer box body is embedded into the second retaining plate of the lower layer box body, so that the second through hole is aligned with the first and third through holes, and the latch is inserted to complete the vertical and horizontal bidirectional locking. This design replaces the traditional gravity or buckle scheme with a mechanical latch structure, effectively solving the problem of unstable stacking and susceptibility to vibration, significantly improving the stability of the equipment during handling or in a dynamic environment. Meanwhile, the linear arrangement of the notch and mounting hole further optimizes the positioning accuracy, and is suitable for high-reliability scenarios such as performance equipment.

Description

Technical Field

[0001] This utility model relates to the field of audio equipment, and in particular to a stackable amplifier box. Background Technology

[0002] A power amplifier box is an electronic device used to amplify low-power audio signals to a level sufficient to drive speakers or audio equipment. It typically integrates amplification circuitry and interfaces in a box-like shape and is one of the core components of an audio system.

[0003] In existing technologies, power amplifier boxes have the following problems:

[0004] 1. Insufficient mechanical locking: Traditional power amplifier boxes rely on gravity or simple latches for stacking, which are easily affected by vibration and handling, leading to displacement or even falling.

[0005] 2. Simple interface: It only uses a bottom groove and a top protrusion for nesting, and there is no horizontal locking, which poses a risk of lateral slippage (such as stage equipment shaking). Utility Model Content

[0007] Box body (1), the two sides of the box body (1) are provided with through holes (11), and the bottom of the side wall of the box body (1) is provided with slots (12).

[0008] The connecting component (2) includes a first retaining plate (21), a second retaining plate (22), a third retaining plate (23), and a pin (24). The first retaining plate (21), the second retaining plate (22), and the third retaining plate (23) are staggered and fixedly arranged. The gap between the first retaining plate (21) and the third retaining plate (23) forms a retaining space (25). The retaining space (25) matches the width of the second retaining plate (22).

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the stackable power amplifier box of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figures 1 to 4 This utility model discloses a stackable power amplifier box, the core components of which include a box body (1) and connecting parts (2). The box body (1) is the main shell of the power amplifier device, and its structural feature is that it has slots (11) on both sides. These slots (11) are openings through the box body (1), providing channels for the connecting parts (2) to be embedded and installed. In addition, the bottom of the side wall of the box body (1) is specially designed with a groove (12). When the power amplifier boxes (1) are stacked, the groove (12) can accommodate the lower part of the connecting parts (2) of the upper box body (1) and cooperate with the corresponding structure of the lower box body (1) to ensure the initial positioning of the stack.

[0025] The connecting component (2) is the key structure for achieving stacking locking. It consists of a first retaining plate (21), a second retaining plate (22), a third retaining plate (23), and a pin (24). These three retaining plates are fixed in a staggered stacking manner to form an internal structure. Specifically, an internal retaining space (25) is formed between the first retaining plate (21) and the third retaining plate (23). The size of this retaining space (25) matches the width of the second retaining plate (22), ensuring that the second retaining plate (22) can be tightly and gaplessly embedded.

[0026] To achieve the locking function, the first retaining plate (21) has a first through hole (211) in the side wall region near the bottom. Similarly, the third retaining plate (23) has a third through hole (231) in the side wall region near the bottom. Meanwhile, the second retaining plate (22) has a second through hole (221) in the side wall region near the top.

[0027] When two amplifier boxes (1) need to be stacked, one amplifier box (1) acts as the lower unit, with its connecting part (2) remaining fixed. The other amplifier box (1) acts as the upper unit, with its retaining space (25) vertically lowered and embedded into the second retaining plate (22) of the connecting part (2) of the lower amplifier box (1). Once the second retaining plate (22) is fully embedded in the retaining space (25), a crucial alignment is established: the second through hole (221) aligns simultaneously with the first through hole (211) and the third through hole (231). At this point, the pin (24) is manually or automatically passed through these aligned through holes. The insertion of the pin (24) effectively locks the upper box (1) and the lower box (1) in the vertical and horizontal directions, thereby preventing accidental separation or relative sliding between the boxes (1).

[0028] This locking mechanism provides a reliable mechanical connection, solving the problems of stacking instability and susceptibility to vibration caused by relying solely on gravity or simple latches in existing technologies. Its beneficial effect is that it significantly enhances the structural stability and security of stacked amplifier equipment, maintaining a secure connection even during transport or high-dynamic performance environments.

[0029] Please see Figures 1 to 4 In another embodiment, to facilitate the installation and fixation of the connecting component (2) on the housing (1), at least one mounting hole (13) is additionally provided on the side wall of the housing (1). These mounting holes (13) are preset fixing points used to securely anchor the connecting component (2) inside the housing (1) with external fasteners. To optimize the accuracy and efficiency of the installation process, in a preferred embodiment, the at least one mounting hole (13) is aligned in a straight line with the slot (12). This geometric arrangement ensures precise alignment of the connecting component (2) during installation, simplifies the assembly process, and improves the consistency of mass production.

[0030] Its beneficial effect is that by providing clear mounting points and alignment methods, it effectively reduces installation errors, improves the reliability of fixing the connecting parts (2) on the box (1), and thus enhances the structural integrity of the entire stacking system.

[0031] Please see Figures 1 to 4In another embodiment, in order to form a complete fixing loop with the mounting holes (13) on the housing (1), the sidewall of the first retaining plate (21) is provided with retaining holes (212). These retaining holes (212) are matched in size and position with the mounting holes (13) on the housing (1). When the connecting component (2) is correctly inserted into the slot (11) of the housing (1) and reaches its predetermined installation position, the mounting holes (13) will be aligned with the retaining holes (212). At this time, the connecting component (2) can be firmly fixed inside the housing (1) by passing bolts, rivets or other suitable mechanical fasteners through the aligned mounting holes (13) and retaining holes (212).

[0032] This design, by establishing additional fixing points, prevents the connecting parts (2) from loosening or shifting during long-term use or under external loads, further ensuring the overall structural stability of the stacked amplifier box.

[0033] Please see Figures 1 to 4 In another embodiment, to improve the ease of handling the equipment, the present invention is further equipped with a lifting part (3). The lifting part (3) is designed with multiple hanging holes (31). These hanging holes (31) provide flexible connection points that can be used to connect lifting slings, handles or any auxiliary handling tools, which greatly simplifies the movement and deployment of the amplifier box (1) between different sites, especially in scenarios that require frequent handling or operation in confined spaces.

[0034] In a preferred embodiment, the lifting part (3) is provided on the top of the housing (1) by a threaded connection. This threaded connection allows users to easily install or remove the lifting part (3) according to their actual needs. For example, when hoisting is not required, users can choose to remove it to maintain the simplicity of the equipment's appearance; and when transportation is required, it can be quickly and easily reinstalled.

[0035] The design of the lifting part (3), especially its detachable threaded connection, gives the amplifier box (1) greater flexibility and ease of operation, effectively improving the user experience.

[0036] Please see Figures 1 to 4 In another embodiment, to ensure that the retaining plates inside the connecting component (2) have sufficient structural strength and integrity, the first retaining plate (21), the second retaining plate (22) and the third retaining plate (23) are connected by welding.

[0037] The application of welding connections significantly improves the mechanical strength and durability of the connecting components (2), ensuring the reliability and safety of the entire stackable amplifier box system in harsh operating environments.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
