Description

Technical Field

[0001] This utility model belongs to the field of power amplifier structure technology, specifically relating to an outdoor power amplifier. Background Technology

[0002] A power amplifier is a central control device used to adjust the playback effect of audio equipment. Currently, power amplifiers are usually connected using audio cables. However, in outdoor settings, due to the lack of a suitable platform, the power amplifier often has to be placed directly on the speaker for operation. On the one hand, this makes it easy for the amplifier to slip due to vibrations generated during playback, and on the other hand, it is not easy for the operator to avoid the speaker in the playback environment. On the other hand, setting up a separate control platform is inconvenient for carrying too much equipment outdoors, and the variable outdoor environment also presents problems for equipment use, operation, and protection. Summary of the Invention

[0003] The purpose of this utility model is to provide an outdoor power amplifier to solve the problems mentioned in the background art.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: An outdoor power amplifier includes an amplifier body and a cabinet, wherein the amplifier body is disposed in the cabinet and the cabinet is provided with an adjustment mechanism that is connected and matched to the power amplifier. The lifting assembly is a device in the adjustment mechanism used to adjust the height of the power amplifier body, and the lifting assembly is installed inside the enclosure; A support plate, which is used to support and install the amplifier body, is hinged to the lifting assembly and its length is less than the inner cavity height of the enclosure. The support foot is a device used to assist in supporting the support plate, and the support foot is located at the other end of the support plate relative to the mounting of the power amplifier body.

[0005] The lifting assembly consists of a screw, a rotating rod, and a connecting plate. The screw is rotatably located on the rear side of the housing, the rotating rod is located on the upper outer side of the housing and is concentrically connected to the screw, and the connecting plate is threadedly connected to the screw and slides up and down within the housing.

[0006] The support plate and the connecting plate are hinged together by flipping up and down, and the flipping angle of the support plate ranges from parallel to the ground to perpendicular to the ground.

[0007] The support plate is evenly provided with a number of bolt connection holes.

[0008] The support foot is hinged to the support plate and the length of the support foot is less than the length of the support plate.

[0009] The box body has a door at one end, and one side of the door is hinged to the inner cavity of the box body and closed to the box body by a zipper. The box body has a pull rod at the end away from the door, and a caster wheel is provided at the lower end of the box body near the pull rod. The box body also has a fixed foot at the lower end of the box body near the door.

[0010] This application has at least the following advantages compared to the prior art: By using the enclosure and support plate, a convenient and safer support platform can be provided for power amplifier equipment when used outdoors.

[0017] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1-4 As shown, an outdoor power amplifier includes a power amplifier body 1 and a cabinet 2. The power amplifier body 1 is disposed inside the cabinet 2, and the cabinet 2 is provided with an adjustment mechanism that is connected and matched to the power amplifier. The lifting assembly is a device in the adjustment mechanism used to adjust the height of the power amplifier body 1. The lifting assembly is installed inside the housing 2. Support plate 3 is used to support and install the power amplifier body 1. The support plate 3 is hinged to the lifting assembly and its length is less than the inner cavity height of the cabinet 2. Support foot 31 is a device used to assist in supporting support plate 3. Support foot 31 is located at the other end of support plate 3 relative to the mounting power amplifier body 1.

[0019] When using the amplifier body 1 in an outdoor environment, in fact, in any environment where it is not possible to directly place the amplifier body 1 for use, it can be used in combination with the cabinet 2 and adjustment mechanism described in this application. When using it in combination, first open the cabinet 2, then extend the support plate 3 to unfold the support plate 3 to form a platform that can be used to place the amplifier body 1 or other equipment. Then, adjust the height of the support plate 3 according to the usage environment through the lifting component. Finally, the support feet 31 provide auxiliary support for the support plate 3, thereby completing the overall usage environment unfolding of the amplifier body 1. This provides a relatively stable usage environment on the one hand, and makes it easier for the user to operate the amplifier on the other hand.

[0020] The lifting assembly consists of a screw 4, a rotating rod 41, and a connecting plate 42. The screw 4 is rotatably located inside the rear of the housing 2. The rotating rod is located on the upper outer side of the housing 2 and is concentrically connected to the screw 4. The connecting plate 42 is threadedly connected to the screw 4 and slides up and down inside the housing 2.

[0021] During adjustment, the screw 4 can be driven to rotate directly by rotating the rotary rod 41. Since the connecting plate 42 is connected to the screw 4 and is restricted by the guiding space inside the housing 2, the connecting plate 42 can only move up or down by rotating the screw 4. In this way, the height of the connecting plate 42 can be adjusted by controlling the rotation direction of the rotating screw 4, thereby adjusting the working height of the support plate 3.

[0022] The support plate 3 and the connecting plate 42 are hinged together by flipping up and down, and the flipping angle of the support plate 3 is from parallel to the ground to perpendicular to the ground.

[0023] The support plate 3 and the connecting plate 42 are hinged together, allowing the entire support plate 3 to be stored in the storage space of the housing 2 when not in use. This reduces exposed parts and makes the entire device more portable. The rotatable angle of the support plate 3 is limited to the angle between parallel and perpendicular to the ground, satisfying the rotatable angle limitation for storage or use, and preventing excessive rotatability. In some embodiments, the support plate 3 and the connecting plate 42 can be connected by a damping hinge, providing a certain damping force to prevent the support plate 3 from rotating automatically. Other embodiments use a pin between the support plate 3 and the connecting plate 42. When the support plate 3 is rotated to parallel or perpendicular to the ground, the pin connects the rotation areas of the support plate 3 and the connecting plate 42, with the connection being eccentric relative to the rotation point. This directly restricts the support plate 3 from rotating. However, those skilled in the art are not limited to the methods defined in this application in restricting the rotation of the support plate 3; therefore, this application will not elaborate further, but those skilled in the art should understand or choose appropriate methods for implementation.

[0024] The support plate 3 is evenly provided with a number of bolt connection holes 32.

[0025] The bolt connection holes 32 on the support plate 3 are set at equal intervals, which can match the connection and fixing needs of different sizes and types of power amplifier bodies 1 during use. At the same time, this allows the power amplifier body 1 to be directly installed on the support plate 3, so that it can be directly stored in the cabinet 2 for carrying when the power amplifier is not in use, providing a more portable and highly protective effect for the power amplifier body 1 in outdoor environments.

[0026] The support foot 31 is hinged to the support plate 3 and the length of the support foot 31 is less than the length of the support plate 3.

[0027] The support foot 31 can provide auxiliary support for the support plate 3, transfer the center of gravity and prevent the amplifier from tipping over due to instability after it is installed on the unfolded support plate 3. The length of the support foot 31 is less than the length of the support plate 3, which makes it easier to unfold the support foot 31. After unfolding, the support foot 31 can be made to contact the ground by adjusting the lifting component. The support foot 31 can be flipped and limited by the same connection method between the support plate 3 and the connecting plate 42, such as damping hinge or by means of a pin, to further restrict the position of the support foot 31 and improve the stability of the support foot 31.

[0028] One end of the box body 2 is provided with a door 21. One side of the door 21 is hinged to the inner cavity of the box body 2 and closed to the box body 2 by a zipper. The end of the box body 2 away from the door 21 is provided with a pull rod 22. The lower end of the box body 2 near the pull rod 22 is provided with a caster wheel 23. The lower end of the box body 2 near the door 21 is provided with a fixed foot 24.

[0029] The door 21 can be made of flexible materials such as nylon or fabric, or it can be made directly from plastic sheet. The connection method using a zipper is a common connection method for luggage products. Although it is not shown in the illustrations of this application, those skilled in the art should understand its connection principle and setting method. After setting the door 21, the adjustment mechanism set inside the case 2 can be operated directly by opening the door 21. The pull rod 22 makes it easy to carry and pull after storing all the components inside the case 2. The universal wheels 23 make it easier to move the device with less effort. The fixed feet 24, together with the support feet 31, can increase the friction with the ground when supporting, and improve the stability of the support.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
