[0002] PCB, or Printed Circuit Board, is a carrier for the electrical interconnection of electronic components. A PCB generally consists of an insulating base plate, connecting wires, and pads for assembling and soldering electronic components. It serves the dual function of conductive lines and an insulating base plate. When testing a PCB, a fixing device is usually needed to limit and fix the PCB board to prevent it from moving during the testing process.

[0003] However, most existing PCB board inspection and fixing devices are not convenient for limiting and fixing PCB boards of different sizes, and most of them are difficult to adjust the fixing position, making it inconvenient to adjust the fixing position of the board according to the change of the inspection position, thus having certain defects in use. Therefore, we propose a PCB board fixing device that is convenient for PCB board inspection in order to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a PCB board fixing device that facilitates PCB board inspection, so as to solve the problems mentioned in the background art that most existing PCB board inspection fixing devices are not convenient for limiting and fixing PCB boards of different sizes, and are mostly difficult to adjust the fixing position, making it inconvenient to adjust the fixing position of the board according to the change of the inspection position.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a PCB board fixing device for easy PCB board inspection, comprising a fixing frame, wherein an installation groove is provided inside the fixing frame, and a connecting rod is provided inside the installation groove, wherein a first adjusting component is connected to the outside of the connecting rod, and the first adjusting component includes a moving block;

[0006] A fixing block is fixedly connected to one outer end face of the fixed frame, and a second adjusting component is connected to the upper end of the fixing block. The second adjusting component includes a second connecting rod that is rotatably connected to the fixing block. Both the first adjusting component and the second adjusting component are connected to a limiting structure on the end face of the fixed frame. The limiting structure includes a pressure block disposed above the fixed frame.

[0007] As a preferred technical solution of this utility model, a fixing groove for placement is provided on the end face of the fixed frame near the limiting structure.

[0008] As a preferred embodiment of this utility model, the connecting rod is rotatably disposed inside the mounting groove, and both ends of the connecting rod are fixedly connected to adjusting blocks, which are disposed on the outside of the fixed frame. The outer surface of the connecting rod is provided with external threads.

[0009] As a preferred embodiment of this utility model, the movable block has a through hole structure inside, and the inner surface of the through hole structure is provided with an internal thread. The connecting rod is threadedly connected to the movable block through the through hole structure.

[0010] As a preferred embodiment of the present invention, the first adjustment component further includes a first connecting rod rotatably connected to the top of the moving block, and a swing rod rotatably connected to the outer side of the first connecting rod. The moving block is slidably connected to the fixed frame through a mounting groove.

[0011] As a preferred embodiment of the present invention, the second adjustment assembly further includes a first adjustment handle disposed above the fixed groove, and one end of the first adjustment handle is rotatably connected to the outside of the second connecting rod, and the other end of the first adjustment handle is rotatably connected to a second adjustment handle.

[0012] As a preferred embodiment of this utility model, the second adjusting handle and the swing rod are both fixedly connected to a fixed cylinder on the side face near the fixed frame, and a spring is provided inside the fixed cylinder. A movable rod is slidably connected inside the fixed cylinder on the inner side of the spring, and a pressure block is fixedly connected to the bottom end of the movable rod.

[0013] As a preferred embodiment of this utility model, the bottom surface of the fixed frame is evenly distributed with pads that provide support.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the PCB board fixing device that facilitates PCB board inspection solves the problems that most existing PCB board inspection fixing devices are not convenient for limiting and fixing PCB boards of different sizes, and are mostly difficult to adjust the fixing position, making it inconvenient to adjust the fixing position of the PCB board according to the change of the inspection position.

[0015] 1. By rotating the adjusting block, the first adjusting component can be moved inside the mounting slot, thereby moving the limiting structure above the fixed slot. The swing rod can rotate relative to the moving block, thereby adjusting the position of the limiting structure above the fixed slot. The elastic force of the spring causes the movable rod and the pressure block to push out to one side of the fixed slot, thereby pressing the PCB board against the pressure block, which is convenient for limiting and fixing PCB boards of different sizes.

[0016] 2. By rotating the first and second adjusting handles, the position of the limiting structure at the lower end of the second adjusting handle changes relative to each other, making it convenient to adjust the position of the limiting structure above the PCB board. Loosening the pressure block allows the spring force to push the movable rod and pressure block towards one side of the fixing groove, thereby pressing the PCB board against the pressure block. This facilitates adjusting the fixing position of the board according to changes in the detection position. The pressure block positions the PCB board at three points, improving the fixing stability of the PCB board and making the PCB board more practical during the fixing process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a PCB board fixing device for easy PCB board inspection, including a fixing frame 1, an installation groove 3 inside the fixing frame 1, and a connecting rod 4 inside the installation groove 3. A fixing groove 2 for placement is provided on the end face of the fixing frame 1 near the limiting structure 900. A first adjusting component 600 is connected to the outside of the connecting rod 4, and the first adjusting component 600 includes a moving block 601. The moving block 601 has a through hole structure inside, and the inner surface of the through hole structure has an internal thread. The connecting rod 4 is rotatably disposed inside the installation groove 3, and both ends of the connecting rod 4 are fixedly connected to adjusting blocks 5, which are disposed on the outside of the fixing frame 1. The outer surface of the connecting rod 4 has an external thread. Figure 1 and Figure 4 As shown, the connecting rod 4 is threadedly connected to the moving block 601 through the through hole structure. By rotating the adjusting block 5, the first adjusting component 600 can move inside the mounting groove 3, thereby allowing the limiting structure 900 to move above the fixing groove 2.

[0024] Specific examples Figure 1 and Figure 2 As shown, the first adjustment assembly 600 also includes a first connecting rod 603 rotatably connected to the top of the moving block 601, and a swing rod 602 rotatably connected to the outer side of the first connecting rod 603. A fixed cylinder 901 is fixedly connected to the end face of the swing rod 602 near the fixed frame 1. The swing rod 602 can rotate relative to the moving block 601, thereby adjusting the position of the limiting structure 900 above the fixed groove 2.

[0025] Specific examples Figure 1 As shown, a fixing block 7 is fixedly connected to one outer end face of the fixing frame 1, and a second adjusting component 800 is connected to the upper end of the fixing block 7. The second adjusting component 800 includes a second connecting rod 803 rotatably connected to the fixing block 7. The second adjusting component 800 also includes a first adjusting handle 801 disposed above the fixing groove 2. One end of the first adjusting handle 801 is rotatably connected to the outside of the second connecting rod 803, and the other end of the first adjusting handle 801 is rotatably connected to a second adjusting handle 802. Since a fixing cylinder 901 is fixedly connected to the end face of the second adjusting handle 802 near the fixing frame 1, when the first adjusting handle 801 and the second adjusting handle 802 rotate relative to the axis of the second connecting rod 803, the position of the limiting structure 900 above the fixing groove 2 can be adjusted.

[0026] Specific examples Figure 1 and Figure 4As shown, the bottom surface of the fixed frame 1 is evenly distributed with pads 10 that provide support. The limiting structure 900 includes a pressure block 904 disposed above the fixed frame 1. A spring 903 is disposed inside the fixed cylinder 901. A movable rod 902 is slidably connected inside the fixed cylinder 901 on the inner side of the spring 903. The bottom end of the movable rod 902 is fixedly connected to the pressure block 904. Through the elastic force of the spring 903, the movable rod 902 and the pressure block 904 can be pushed out to one side of the fixed groove 2. When the PCB board is placed inside the fixed groove 2, the pressure block 904 can hold the PCB board in place.

[0027] The working principle of this utility model is as follows: When using this PCB board fixing device that facilitates PCB board inspection, the PCB board is first placed inside the fixing groove 2, specifically as follows: Figure 1 As shown, by rotating the adjusting block 5, the first adjusting component 600 can be moved inside the mounting groove 3, thereby causing the limiting structure 900 to move above the fixed groove 2. By rotating the swing rod 602, the position of the limiting structure 900 above the PCB board can be adjusted so that the limiting structure 900 is located at the position that needs to be limited above the PCB board. When the pressure block 904 is released, the elastic force of the spring 903 causes the movable rod 902 and the pressure block 904 to push out to one side of the fixed groove 2, thereby causing the pressure block 904 to hold the PCB board in place.

[0028] Specific examples Figure 1 and Figure 3 As shown, when adjusting the detection position of the PCB board, by rotating the first adjusting handle 801 and the second adjusting handle 802, the position of the limiting structure 900 at the lower end of the second adjusting handle 802 is relatively changed, the position of the limiting structure 900 above the PCB board is adjusted, the pressure block 904 is released, and the elastic force of the spring 903 causes the movable rod 902 and the pressure block 904 to push out to one side of the fixing groove 2, thereby causing the pressure block 904 to hold the PCB board in place. The pressure block 904 positions the PCB board at three points, improving the stability of the PCB board.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
