Description

Technical Field

[0001] This invention relates to the field of power amplifier technology, and more specifically, to a power amplifier mounting device. Background Technology

[0002] The primary purpose of power amplifier mounting devices is to stably position and secure the power amplifier, thereby improving its overall stability. These devices typically include components such as mounting brackets, reinforcing bases, and mounting posts, which work together to ensure the power amplifier's stable position.

[0003] A search of existing published technical documents reveals that patent publication number CN207639056U discloses a fixing device for a power amplifier. This device primarily consists of two fixing blocks with rotatably connected shock-absorbing rods at their tops. The ends of the two shock-absorbing rods furthest from the fixing blocks are rotatably connected to a support plate. Inner rods are fixedly connected to the sides of the two fixing blocks furthest from the horizontal support rods. Outer rods are sleeved on the two inner rods. The two outer rods are perpendicularly fixed to both sides of the shock-absorbing groove. Springs are fixedly connected between the two fixing blocks and the outer rods. This device is convenient to use, protects the internal electrical components of the power amplifier, and avoids unnecessary damage. However, this fixing device has the following drawbacks. When fixing power amplifiers, it is difficult to keep multiple power amplifiers in the same position after they are placed, and it is also difficult to maintain the squeezing force during the fixing process. This can lead to the fixing of multiple power amplifiers being too tight or too loose, making it difficult to achieve precise fixing. Therefore, a power amplifier fixing device is provided. Summary of the Invention

[0004] To overcome the above-mentioned defects of the prior art, the present invention provides a power amplifier fixing device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power amplifier fixing device, comprising three fixed support plates, each fixed support plate having two support blocks fixedly installed at its top end, and a pressure positioning mechanism installed at the top end of each support block; the pressure positioning mechanism includes a concave support block fixedly installed at the top end of the support block, and a power amplifier is vertically slidably inserted into the inner wall of the concave support block; a compression spring is installed on one side of the concave support block below the power amplifier, and a compression column and a pressure sensor are sequentially arranged below the compression spring from top to bottom; a sleeve slider is fixedly attached to one side of the outer wall of the compression column by hot melt adhesive, and a guide slide column is vertically slidably connected through the inner wall of the sleeve slider, and a reinforcing support block fixedly connected to the support block is installed at the bottom end of the guide slide column; a force equalizing compression assembly is installed below the fixed support plate.

[0006] Preferably, the three fixed support plates are arranged equidistantly from left to right, and all three fixed support plates are made of stainless steel. The bottom cross-sectional area of ​​the fixed support plate is smaller than the top cross-sectional area. The pressure sensor and the extrusion spring are fixedly connected to the extrusion column. The center point of the extrusion spring and the extrusion column are on the same vertical line. The reinforcing block and the guide slide are integrally formed by die casting, and both the guide slide and the reinforcing block are made of stainless steel.

[0007] When using the above technical solution, the power amplifier drives the two connecting wire ends to move downwards synchronously. When the power amplifier moves downwards, it can be inserted into the inner wall of the concave support block. The three power amplifiers are respectively inserted into the three concave support blocks. When the power amplifier moves downwards, it will contact the extrusion spring. The extrusion column drives the sleeve slider to move downwards. At the same time, the sleeve slider slides down along the outer wall of the guide column. The support block provides a reinforcing force to the pressure sensor. The pressure sensor realizes pressure sensing at the bottom of the extrusion column. When the sensed pressure value is the same as the pressure value set by the controller, the position of the power amplifier inserted into the concave support block is at the designated pressure sensing position, improving the fixing accuracy.

[0008] Preferably, the force-equalizing extrusion assembly includes a guide frame fixedly installed below the fixed support plate, and a controller is fixedly installed on one side of the guide frame. A linkage screw is rotatably installed on the inner wall of the guide frame via a bearing. A drive motor for driving the linkage screw to rotate is fixedly installed at one end of the guide frame. Two threaded sleeves are arranged sequentially from right to left on the outer wall of the linkage screw. A linkage extrusion plate is fixedly installed at the top of each threaded sleeve. An extrusion sleeve for extruding a fixed power amplifier is welded to the top of the linkage extrusion plate. A calibration pressure sensor and an extrusion support are arranged sequentially from bottom to top on one side of the extrusion sleeve. A linkage extrusion assembly is arranged on one side of the extrusion sleeve and below the calibration pressure sensor. The output end of the drive motor is coaxially connected to one end of the linkage screw. The guide frame and the linkage screw are both made of stainless steel. Both threaded sleeves are threadedly connected to the outer wall of the linkage screw. The two threads on the outer wall of the linkage screw are opposite and symmetrically arranged. The two threaded sleeves are horizontally slidably connected to the inner wall of the guide frame.

[0009] According to the above technical solution, during use, the drive motor drives the linkage screw to rotate. The linkage screw rotates stably inside the guide frame. During the rotation, the linkage screw drives two threaded sleeves to approach each other under the action of the threads. The two threaded sleeves slide closer along the inner wall of the guide frame. During the movement of the two threaded sleeves, they respectively drive two linkage extrusion plates to move. The extrusion sleeves carry the extrusion support blocks to the internal position of the power amplifier. The extrusion sleeves drive the calibration pressure sensor to press on the positioning pressure plate, so that the pressure value sensed by the calibration pressure sensor is the same as the pressure value set by the controller. Then, the controller shuts off the drive motor to achieve precise extrusion and fixation.

[0010] Preferably, the linkage extrusion assembly includes a linkage support block fixedly disposed on one side of the extrusion sleeve block and located below the calibration pressure sensor; four sleeve support blocks are installed on one side of the linkage support block, and a guide slide rod is fixedly connected through the inner wall of the sleeve support block. A guide sleeve is fixedly connected to the outer wall of the guide slide rod near both ends. The outer wall of the guide sleeve is horizontally slidably connected to the inner wall of the extrusion sleeve block. Linkage brackets are installed on both sides of the linkage support block, and two linkage support blocks are fixedly connected to the linkage brackets. Two positioning pressure plates are fixedly connected to the bottom end of the power amplifier near its middle position. A cover plate is glued and fixed to the upper surface of the power amplifier. Two connecting wire ends are welded to one side of the power amplifier, and the center points of the two connecting wire ends are at the same horizontal line position.

[0011] When in use, according to the above technical solution, the extrusion sleeve block drives the linkage support block to move, the linkage support block causes the two linkage brackets to move, and the two linkage brackets respectively drive the other two extrusion sleeve blocks to move. The six extrusion sleeve blocks move synchronously. The drive motor is turned off by the controller, and the three power amplifiers can achieve extrusion and fixation according to the specified pressure. The extrusion sleeve block slides along the outer wall of the guide sleeve, and the sleeve support block provides support force to the guide slide rod. The six guide slide rods play a supporting role synchronously, providing guidance and extrusion fixing operation for the power amplifier, making the extrusion and fixation more secure.

[0012] The technical effects and advantages of this invention are as follows: 1. This invention utilizes a pressure positioning mechanism to allow the power amplifier to be inserted into the inner wall of the concave support block when it moves downward. The support block is supported by a fixed support plate. Three power amplifiers are respectively inserted into the three concave support blocks. The extrusion spring moves the extrusion column downward, and the extrusion column moves the sleeve slider downward. The support block provides reinforcement to the pressure sensor. The pressure sensor senses the pressure at the bottom of the extrusion column. When the sensed pressure value is the same as the pressure value set by the controller, it is known that the three power amplifiers can be extruded downward at the specified position and the three power amplifiers can be positioned and fixed according to the specified pressure. This avoids the multiple power amplifiers being fixed too tightly or too loosely, and improves the fixing accuracy of the power amplifiers. 2. This invention uses a force-equalizing extrusion assembly to start the drive motor. The drive motor drives the linkage screw to rotate. The linkage screw drives two threaded sleeves to approach each other under the action of the threads. At the same time, the two threaded sleeves slide closer along the inner wall of the guide frame. The two linkage extrusion plates drive the two extrusion sleeves to push. If the pressure value sensed by the pressure sensor is the same as the pressure value set by the controller, the drive motor is turned off by the controller. It can achieve fixed operation of the power amplifier according to the specified fixed pressure, and the power amplifier is fixed more accurately. 3. This invention uses a linkage extrusion assembly to move the extrusion sleeve block, which in turn moves the linkage support block. The linkage support block moves two linkage brackets, which in turn move two other extrusion sleeve blocks. This enables the six extrusion sleeve blocks to move synchronously, allowing the three power amplifiers to be extruded and fixed according to a specified pressure. The extrusion sleeve blocks slide along the outer wall of the guide sleeve, while the fixed support plate provides support for the sleeved support block. This provides precise lateral fixing pressure to the power amplifiers, making the extrusion more precise and preventing the fixing force from shifting. Through the interaction of the above-mentioned multiple functions, the three power amplifiers can be squeezed and positioned downwards according to the specified pressure and position. The two linkage extrusion plates drive the two extrusion sleeves to push. The pressure value sensed by the pressure sensor is the same as the pressure value set by the controller, so that the six extrusion sleeves move synchronously. The three power amplifiers can be squeezed and fixed according to the specified pressure. In summary, the same pressure sensing position can be maintained for the placement of multiple power amplifiers. When multiple power amplifiers are fixed, they can be fixed synchronously and accurately according to the specified pressure, which greatly improves the fixing accuracy. Attached Figure Description

A force equalization compression assembly is installed below the fixed support plate 1.

[0023] In this embodiment, as shown in the appendix Figure 4-7 As shown, the force-equalizing extrusion assembly includes a guide frame 11 fixedly installed below the fixed support plate 1, and a controller 12 fixedly installed on one side of the guide frame 11. A linkage screw 13 is rotatably installed on the inner wall of the guide frame 11 via a bearing. A drive motor 14 for driving the linkage screw 13 to rotate is fixedly installed at one end of the guide frame 11. Two threaded sleeves 15 are arranged sequentially from right to left on the outer wall of the linkage screw 13. A linkage extrusion plate 16 is fixedly installed at the top of each threaded sleeve 15. An extrusion sleeve for extruding the fixed power amplifier 4 is welded to the top of the linkage extrusion plate 16. Block 17, from bottom to top, is provided with a calibration pressure sensor 18 and a compression support block 19 on one side of the compression sleeve block 17; a linkage compression assembly is provided on one side of the compression sleeve block 17 and below the calibration pressure sensor 18, the output end of the drive motor 14 is coaxially connected to one end of the linkage screw 13, and both the guide frame 11 and the linkage screw 13 are made of stainless steel, and both threaded sleeves 15 are threaded to the outer wall of the linkage screw 13, the two threads on the outer wall of the linkage screw 13 are opposite and symmetrically opened; the two threaded sleeves 15 are horizontally slidably connected to the inner wall of the guide frame 11.

[0024] In this embodiment, as shown in the appendix Figure 6-7 As shown, the linkage extrusion assembly includes a linkage support block 20 fixedly installed on one side of the extrusion sleeve block 17 and located below the calibration pressure sensor 18; four sleeve support blocks 22 are installed on one side of the linkage support block 20, and a guide slide rod 21 is fixedly connected through the inner wall of the sleeve support block 22. A guide slide sleeve 25 is fixedly connected to the outer wall of the guide slide rod 21 near its two ends. The outer wall of the guide slide sleeve 25 is horizontally slidably connected to the inner wall of the extrusion sleeve block 17. Linkage brackets 23 are installed on both sides of the linkage support block 20, and the two linkage support blocks 20 are fixedly connected to the linkage brackets 23. Two positioning pressure plates 24 are fixedly connected to the bottom end of the power amplifier 4 near its middle position. A cover plate 26 is glued and fixed to the upper surface of the power amplifier 4. Two connecting wire ends 27 are welded to one side of the power amplifier 4, and the center points of the two connecting wire ends 27 are at the same horizontal line position.

[0025] The working principle of the power amplifier fixing device of the present invention is as follows: First, during constant pressure placement, the power amplifier 4 is moved downwards. The power amplifier 4 causes the cover plate 26 to move downwards, and simultaneously, the power amplifier 4 causes the two connecting wire ends 27 to move downwards synchronously. This allows the power amplifier 4 to insert into the inner wall of the concave support block 3. The fixed support plate 1 provides support to the support block 2, and the support block 2 provides support to the concave support block 3. Thus, the three power amplifiers 4 are inserted into the three concave support blocks 3 respectively. As the power amplifier 4 moves downwards, it contacts the compression spring 5. The compression spring 5 causes the compression column 6 to move downwards, and the compression column 6 causes the sleeve slider 8 to move downwards. Simultaneously, the sleeve slider 8 moves along the guide column... The outer wall of 9 is guided downwards, while the support block 2 provides support force to the reinforcing block 10. The reinforcing block 10 provides vertical stability support force to the guide slide 9. The support block 2 provides reinforcement force to the pressure sensor 7. The pressure sensor 7 realizes pressure sensing at the bottom of the extrusion column 6. When the sensed pressure value is the same as the pressure value set by the controller 12, it is known that the three power amplifiers 4 can be extruded downwards at the specified position. The position of the power amplifier 4 inserted into the concave block 3 is at the specified pressure sensing position. Thus, the three power amplifiers 4 can be positioned and fixed according to the specified pressure, avoiding tilting that causes the extrusion to be too loose or too tight, and improving the fixing accuracy. Secondly, during the extrusion process, the controller 12 starts the drive motor 14, which drives the linkage screw 13 to rotate. The linkage screw 13 rotates stably inside the guide frame 11. During the rotation, the linkage screw 13 drives the two threaded sleeve blocks 15 to move closer to each other under the action of the threads. At the same time, the two threaded sleeve blocks 15 slide closer along the inner wall of the guide frame 11. During the movement, the two threaded sleeve blocks 15 drive the two linkage extrusion plates 16 to move. The two linkage extrusion plates 16 drive the two extrusion sleeve blocks 17 to push. The extrusion sleeve blocks 17 carry the extrusion support block 19 and extrude into the internal position of the power amplifier 4. Finally, during the linkage extrusion of this invention, the extrusion sleeve 17 drives the linkage support block 20 to move, the linkage support block 20 causes the two linkage brackets 23 to move, and the two linkage brackets 23 respectively drive the other two extrusion sleeves 17 to move, enabling the six extrusion sleeves 17 to move synchronously. At the same time, the extrusion sleeves 17 drive the calibration pressure sensor 18 to press on the positioning pressure plate 24, so that the pressure value sensed by the calibration pressure sensor 18 is the same as the pressure value set by the controller 12. Then, the controller 12 shuts off the drive motor 14, and the three power amplifiers 4 can be extruded and fixed according to the specified pressure. The extrusion sleeves 17 slide along the outer wall of the guide sleeve 25, and the fixed support plate 1 provides support force to the sleeve support block 22. The sleeve support block 22 provides support force to the guide slide rod 21. The six guide slide rods 21 provide support synchronously, and the guide slide rods 21 provide support to the guide sleeve 25. This ensures that the extrusion sleeves 17 can slide along the outer wall of the guide sleeve 25, and can provide precise fixing pressure to the power amplifiers 4.
