Referring to the drawings, in this embodiment, a placement device for a PCB board may include: a base plate 1, a fixed plate 2, a damping rotor 3 and a fixed assembly 4. Wherein, fixed dull and stereotyped 2 are located bottom plate 1 top, and damping rotates 3 and is used for connecting bottom plate 1 and fixed dull and stereotyped 2, and fixed subassembly 4 are located fixed dull and stereotyped 2's both ends department for it is fixed to carry out the centre gripping to the PCB board limit. Specifically, when fixing the PCB to be overhauled, firstly, the PCB is placed on the fixed flat plate 2, and then the length of the fixed component 4 is adjusted, so that the fixed component 4 can clamp the edge of the PCB, and then the fixed component 4 is locked to keep clamping the PCB, and at the moment, the fixing of the PCB is completed.

Compared with the prior fixing mode, the fixing method is simpler and more convenient, is more flexible, and can adapt to the PCB with larger size difference. Meanwhile, the bottom plate 1 is connected with the fixed flat plate 2 through the damping rotating piece 3, so that the position adjustment of the PCB can be realized, and the overhaul operation is convenient.

To further explain the damper rotation member 3, this embodiment provides a specific structure of the damper rotation member 3, including: damping shaft 31, first connecting piece 32 and second connecting piece 33. Wherein a first connecting member 32 is fixed to the base plate 1 and is rotatably connected to the damper shaft 31, and a second connecting member 33 is fixed to the fixed plate 2 and is rotatably connected to the damper shaft 31. The adjustment of the position of the clamped PCB board can be achieved by rotating the fixing plate 2. In addition, the base plate 1 is a heavy stainless steel plate in the present embodiment for maintaining stable placement of the fixing plate 2.

The fixing assembly 4 is further described in order to facilitate a clear understanding of the technical solution of the present utility model by a person skilled in the art. In the present embodiment, the fixing unit 4 includes: a rotating shaft 41, a supporting arm 42, a telescopic adjusting rod 43 and a clamping strip 44. Wherein, both ends of the rotating shaft 41 extend out of the shaft hole 5 at the end of the bottom plate 1 and are in clearance fit with the same, one end of the supporting arm 42 is fixed at the end of the rotating shaft 41, the other end is fixed with the corresponding end of the telescopic adjusting rod 43, and the clamping strip 44 is fixed at the corresponding ends of the two telescopic adjusting rods 43 at the same end of the fixed flat plate 2. Specifically, because the rotating shaft 41 is in clearance fit with the shaft hole 5, the rotating shaft 41 can not only rotate in the shaft hole 5, but also axially move to realize the position adjustment of the clamped PCB, the supporting arm 42 is used for supporting the telescopic adjusting rod 43 and the clamping strip 44 at the end part, and when the PCB is clamped, certain support is provided, the telescopic adjusting rod 43 can adjust the length, so that the position of the clamping strip 44 is adjusted, the PCB with different sizes can be clamped, and the applicability is improved.

To further improve the support of the fixing assembly 4 to a larger PCB board and improve the clamping performance, in this embodiment, the end of the support arm 42 near the telescopic adjustment rod 43 is provided with a bearing surface 45. When the PCB board is clamped and fixed, the supporting surface 45 and the top surface of the fixed plate 2 are located on the same plane, so that the external area of the fixed plate 2 can be supported, and the PCB board is prevented from being excessively suspended.

In the present embodiment, in order to enable the clip 44 to accommodate PCB boards of different thicknesses, rubber is used as a material to provide a certain stretchability, and the ends corresponding to the telescopic adjustment lever 43 may be fixed by welding or bolting. Meanwhile, after the PCB board is clamped and fixed, the edge of the PCB board extends into the clamping groove 46 on the clamping strip 44, and the bottom surface of the clamping groove 46 and the top surface of the fixing plate 2 are located on the same plane, so that the top surface of the fixing plate 2, the bearing surface 45 and the clamping groove 46 can synchronously support the PCB board and keep the same level.
