[0002] A power amplifier is generally provided with a metal shell, which usually includes a panel and a top cover, and the panel and the top cover are connected by bolts. For example, the Chinese patent publication number CN206506636U is a combined constant voltage broadcast power amplifier housing structure, which includes a panel, a back panel, a left side panel, a right side panel, a bottom plate and a top cover. The left and right sides of the back of the panel are connected with right-angle connectors, and the upper and lower sides of the back of the panel are provided with screw holes. The front ends of the left and right sides of the left and right sides are connected to the right-angle connectors by screws. The upper and lower sides of the back of the panel are provided with screw holes. The top cover and the bottom plate are connected by screws. The four sides of the back of the back plate are provided with screw holes. The left and right sides of the top cover and the bottom plate are connected by screws. The bottom plate is provided with a stamping machine foot and a transformer boss. The panel is provided with handles on both sides. The power amplifier housing with this connection method is not beautiful in appearance, and the assembly process is relatively cumbersome. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a power amplifier sheet metal combination structure with beautiful appearance and relatively simple assembly process.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a power amplifier sheet metal combination structure, including a panel and a top cover, the front end of the top cover is provided with a buckle bent downward, the buckle is T-shaped, and includes a connecting part and a blocking part; the upper back of the panel is provided with a mounting bar, the mounting bar is provided with a slot corresponding to the buckle position, the front end of the top cover is pressed on the top surface of the mounting bar, and the buckle slot is stuck in the slot. The principle of the utility model: when the top cover is placed on the panel, the T-shaped buckle on the top cover will buckle to the slot of the panel, after the T-shaped buckle of the top cover tightly buckles the slot of the panel, the two sides of the slot of the mounting bar will tightly buckle the blocking part of the T-shaped buckle, thereby playing the role of mutual hooking, without the need for locking screws, the surface of the top cover is simple and beautiful, and no cumbersome locking screws are required.

[0005] As an improvement, the buckle is integrally formed with the top cover.

[0006] As an improvement, the card slot is rectangular with its opening facing rearwards.

[0007] As an improvement, downward flanges are provided on both sides of the top cover, and the two flanges are respectively located at the two ends of the mounting strip.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] The T-shaped buckle of the top cover is buckled with the slot of the panel, and no screws are needed. The surface of the top cover is simple and beautiful, and there is no need for complicated screws. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 5 for Figure 3 Enlarged view of point B. DETAILED DESCRIPTION

[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] like Figures 1 to 5 As shown, a sheet metal combination structure of a power amplifier includes a panel 2 and a top cover 1. The front end of the top cover 1 is provided with a plurality of buckles 11 bent downward by 90 degrees. The buckles 11 are T-shaped and include a connecting portion and a blocking portion. The blocking portion is connected to the top cover 1 through the connecting portion, and the width of the blocking portion is greater than the width of the connecting portion; downward flanges 12 are provided on both sides of the top cover 1; the buckles 11, flanges 12 and the top cover 1 are integrally formed. A mounting strip 3 is provided on the upper back of the panel 2. The mounting strip 3 has a certain thickness and is connected to the panel 2 by welding, gluing or integrally forming; the mounting strip 3 is arranged along the length direction of the panel 2, and a slot 31 is provided on the mounting strip 3 corresponding to the position of the buckle 11. The slot 31 is rectangular and its opening faces backward. After the top cover 1 and the panel 2 are assembled, the front end of the top cover 1 is pressed on the top surface of the mounting bar 3, the buckle groove is clamped at the clamping groove 31, the connecting part is placed in the clamping groove 31, the blocking part is located below the mounting bar 3, and the two flanges 12 are respectively located at both ends of the mounting bar 3. The sheet metal at other positions of the amplifier can be assembled through the above-mentioned connection structure or assembled by screw connection.

[0017] Principle of the utility model: when the top cover 1 is placed on the panel 2, the T-shaped buckle 11 on the top cover 1 will be buckled on the slot 31 of the panel 2. After the T-shaped buckle 11 of the top cover 1 is tightly buckled with the slot 31 of the panel 2, the two side surfaces of the slot 31 of the mounting strip 3 will tightly buckle with the blocking part of the T-shaped buckle 11, thereby playing the role of mutual hooking, without the need for locking screws, the surface of the top cover 1 is simple and beautiful, and no complicated locking screws are required.
