Description

Technical Field

[0001] This utility model relates to the field of power amplifier housings, specifically a screwless power amplifier housing. Background Technology

[0002] The amplifier housing is the external structure that encloses the internal electronic components of the amplifier. It mainly serves functions such as protecting the circuit, heat dissipation, and mechanical support. The amplifier housing is usually a box structure that needs to be assembled.

[0003] Existing power amplifier housings are typically assembled using screws. However, since the housing is made of sheet metal, which is thin and easily deformed, the screw structure can easily cause scratches on the housing when tightening the screws, leading to stress deformation of the internal circuit board and reducing the lifespan of the device. Furthermore, during assembly and disassembly, it is necessary to control the torque of the screws to prevent deformation of the housing or loosening during long-term connection, which increases the operational difficulty and the risk of human error. Utility Model Content

[0004] The purpose of this utility model is to provide a screwless power amplifier housing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A screwless power amplifier housing includes a lower housing, a cover plate, a mounting mechanism, a positioning mechanism, and a support mechanism;

[0007] The mounting mechanism includes multiple fixing buckles, multiple snap-fit ​​components, and multiple sliding components. Each sliding component is fixedly mounted on the top of the cover plate, each snap-fit ​​component is slidably mounted on the sliding component, and each fixing buckle is fixedly mounted on the outer wall surface of the lower housing.

[0008] The positioning mechanism includes multiple positioning pins and multiple positioning slots.

[0009] As a further embodiment of this utility model: each sliding component includes a sliding plate, a pull block, two guide rails and two sliders. Each guide rail is fixedly disposed on one side of the cover plate, each slider is slidably disposed in one guide rail, each slider passes through a fixed bottom, the sliding plate is fixedly disposed between the two sliders, and the pull block is fixedly disposed at one end of one slider away from the sliding plate.

[0010] As a further embodiment of this utility model: each buckle assembly includes two fixing plates, two sleeves, two balls, two rollers and two springs. The two fixing plates are fixedly mounted on the sliding plate. Each sleeve is fixedly mounted on one side of a fixing plate. Each roller is slidably mounted inside a sleeve.

[0013] As a further embodiment of this utility model: a horizontal plate is provided on the top of each second support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model provides a screwless power amplifier housing, which uses a snap-fit ​​design to replace the traditional screw fixing. It eliminates the need for screw assembly of the housing, greatly shortens the installation time, and avoids problems such as scratches on the housing and stress deformation of the internal circuit board caused by tightening screws. It also extends the service life of the equipment, lowers the operation threshold and reduces the risk of human error.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] The present invention provides the following preferred embodiments:

[0025] Example 1, as Figures 1-4 As shown, a screwless power amplifier housing includes a lower housing 1, a cover plate 2, a mounting mechanism, a positioning mechanism, and a support mechanism.

[0026] The mounting mechanism includes multiple fixing buckles 3, multiple snap fasteners and multiple sliding components. Each sliding component is fixedly mounted on the top of the cover plate 2, each snap fastener is slidably mounted on the sliding component, and each fixing buckle 3 is fixedly mounted on the outer wall surface of the lower housing 1.

[0027] The positioning mechanism includes multiple positioning pins 4 and multiple positioning slots 5.

[0028] like Figures 1-4As shown, each sliding assembly includes a sliding plate 6, a pull block 12, two guide rails 13, and two sliders 14. Each guide rail 13 is fixedly mounted on one side of the cover plate 2, and each slider 14 is slidably mounted within one guide rail 13. Specifically, the top of the guide rail 13 is open, and each slider 14 is fixed to the bottom of the guide rail 13 by a bolt 18. Specifically, a through hole is provided on one side of the bottom of the guide rail 13, and a threaded hole is provided on one side of the slider 14. The bolt 18 passes through the through hole and is threadedly connected to the threaded hole. Through the bolt 18, the slider 14 can be stably fixed to the bottom of the guide rail 13. When the buckle assembly is damaged, the bolt 18 can be removed, the pull block 12 can be pulled, and the slider 14 can slide on the guide rail 13 and slide out from the top of the guide rail 13, thereby replacing the buckle assembly. The sliding plate 6 is fixedly mounted between the two sliders 14, and the pull block 12 is fixedly mounted at the end of one of the sliders 14 away from the sliding plate 6.

[0029] When it is necessary to assemble the cover plate 2 and the lower housing 1, first align the cover plate 2 with the lower housing 1, and then press the cover plate 2 onto the lower housing 1. During the pressing process, the buckle assembly will contact the fixing buckle 3. As the cover plate 2 descends, the buckle assembly can engage the fixing buckle 3 to achieve the tight closing of the lower housing 1 and the cover plate 2.

[0030] like Figures 1-4 As shown, each snap-fit ​​assembly includes two fixing plates 7, two sleeves 8, two balls 9, two rollers 10, and two springs 11. The two fixing plates 7 are fixedly mounted on the sliding plate 6. Each sleeve 8 is fixedly mounted on one side of a fixing plate 7. Each roller 10 is slidably mounted inside a sleeve 8. Each ball 9 is rotatably mounted at one end of a roller 10. Each spring 11 is respectively mounted between a sleeve 8 and a roller 10, and the two ends of each spring 11 are fixedly connected to one end of a sleeve 8 and one end of a roller 10, respectively.

[0031] During the closing process of the lower housing 1 and the cover plate 2, that is, when the cover plate 2 moves closer to the lower housing 1, the fixing buckle 3 is first aligned with the position between the two balls 9. When the cover plate 2 moves downward, it can drive the balls 9 to move downward. The balls 9 first contact the protruding section of the fixing buckle 3. As the lower housing 1 and the cover plate 2 continue to move closer, the balls 9 drive the roller 10 to slide away from the fixing buckle 3 inside the sleeve 8. The spring 11 is compressed, and the balls 9 are moved into the inside of the sleeve 8 under the resistance of the fixing buckle 3. As the cover plate 2 continues to move downward, when the balls 9 move to one side of the groove of the fixing buckle 3, the spring 11 can drive the roller 10 to move closer to the groove of the fixing buckle 3 inside the sleeve 8. This can drive the balls 9 to slide out of the inside of the sleeve 8 and lock into the inside of the groove, thus achieving positioning.

[0032] like Figures 1-4As shown, multiple positioning pins 4 are fixedly installed below the cover plate 2, and multiple positioning grooves 5 are opened on the top of the lower housing 1, with each positioning pin 4 inserted into a positioning groove 5.

[0033] During the assembly of the cover plate 2 and the lower housing 1, the multiple positioning pins 4 on the lower part of the cover plate 2 need to be aligned with the positioning grooves 5 on the upper part of the lower housing 1 to continue to drive the cover plate 2 to descend. The positioning pins 4 and positioning grooves 5 guide the cover plate 2 during the descent to prevent the cover plate 2 from shifting.

[0034] like Figures 1-4 As shown, the support mechanism includes two first support plates 16 and four second support plates 17. Each first support plate 16 is fixedly installed on the top of the cover plate 2, and each second support plate 17 is fixedly installed on the top of the lower housing 1.

[0035] After assembly, the bottom of the first support plate 16, which is fixedly set on the top of the cover plate 2, will contact the bottom of the lower housing 1, and the second support plate 17, which is fixedly set on the bottom surface of the lower housing 1, will contact the bottom surface of the cover plate 2. The first support plate 16 and the second support plate 17 will support the cover plate 2 and the lower housing 1 to prevent deformation and other problems from occurring.

[0036] like Figures 1-4 As shown, each second support plate 17 has a horizontal plate 15 on its top. By providing a horizontal plate 15 on the top of each second support plate 17, the contact area between the second support plate 17 and the bottom surface of the cover plate 2 is increased, thereby improving stability.
