[0001] This utility model belongs to the field of electronic manufacturing technology, and in particular relates to a pressing and fixing device for circuit boards. Background Technology

[0002] Circuit boards are increasingly widely used in electronic devices, and their reliability and fastness are crucial to the overall performance of the equipment. Currently, the main methods for connecting and fixing circuit boards are screws, rivets, and adhesives. The circuit board is placed on the surface of a clamping and fixing device, and then fixed by the clamping and fixing device to carry out subsequent work. However, when clamping and fixing the circuit board, it is necessary to place the circuit board inside the card slot. Since the card slot cannot be replaced, it is not convenient to install the circuit board inside the card slot, which makes the process of installing the circuit board inside the card slot relatively complicated and affects the efficiency of fixing the circuit board. Utility Model Content

[0003] This utility model addresses the problem in existing technologies where circuit boards need to be placed inside a mounting plate. Because the mounting plate's slots cannot be replaced, it is inconvenient to install the circuit board inside the slot, making the process complex and affecting the efficiency of securing the circuit board. The following technical solution is proposed:

[0004] A circuit board clamping and fixing device includes a circuit board placement platform, a base rotatably connected to the bottom end of the circuit board placement platform, a clamping plate hinged to the top edge of the circuit board placement platform, a clamping plate rotatably connected inside the circuit board placement platform, positioning blocks slidably connected to both ends of the clamping plate, limit blocks slidably connected to the outer surface of the positioning blocks, a spring fixedly connected to one end of the positioning block, a positioning rod fixedly connected to one end of the spring, a connecting rod movably inserted into the inner side of the positioning rod, the connecting rod being fixedly connected to the inside of the positioning block, and a slider fixedly connected to one end of the connecting rod.

[0005] As a preferred embodiment of the above technical solution, the side shape of the positioning block is set to square, and a groove is provided inside the circuit board placement platform, in which the positioning block is slidably connected.

[0006] As a preferred embodiment of the above technical solution, the connecting rod is located inside the spring and passes through the interior of the positioning rod.

[0007] As a preferred embodiment of the above technical solution, a circular groove is provided inside the card plate, and the limiting block and positioning rod are fixedly connected inside the card plate.

[0008] As a preferred embodiment of the above technical solution, a groove is provided at the bottom of the card plate, and a handle is slidably connected inside the groove, with the handle fixedly connected to the surface of the slider.

[0009] As a preferred embodiment of the above technical solution, a baffle is slidably connected to the top of the base on one side of the pressure plate, and a mounting base is fixedly connected to the bottom of the baffle. A screw is slidably connected inside the mounting base, and a hexagonal nut is threadedly connected to the bottom of the screw. The hexagonal nut is fixedly connected to the inside of the base.

[0010] The beneficial effects of this utility model are as follows:

[0011] (1) By rotating the direction of the slot of the card plate, it is easier for the staff to install the circuit board inside the card plate, which makes the installation method of the circuit board simpler and improves the installation efficiency of the circuit board.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example 1: This utility model provides a circuit board clamping and fixing device, such as... Figures 1 to 5As shown, it includes: a circuit board placement platform 1, a base 2 rotatably connected to the bottom end of the circuit board placement platform 1, a clamping plate 3 hinged to the top edge of the circuit board placement platform 1, a clamping plate 4 rotatably connected inside the circuit board placement platform 1, positioning blocks 5 slidably connected to both ends inside the clamping plate 4, a limit block 6 slidably connected to the outer surface of the positioning block 5, a spring 7 fixedly connected to one end face of the positioning block 5, a positioning rod 8 fixedly connected to one end face of the spring 7, a connecting rod 9 movably inserted into the inner side of the positioning rod 8, the connecting rod 9 fixedly connected to the inside of the positioning block 5, and a slider 10 fixedly connected to one end of the connecting rod 9.

[0021] like Figures 3 to 5 As shown, the side shape of the positioning block 5 is set to square, and the inside of the circuit board placement platform 1 is provided with a sliding groove. The positioning block 5 is slidably connected to the inside of the sliding groove. When the positioning block 5 is open, the card plate 4 can rotate because it is not restricted by the positioning block 5. When the positioning block 5 is closed, the positioning block 5 locks the card plate 4 and the circuit board placement platform 1, making the card plate 4 unable to rotate. This makes the installation of the circuit board more stable and avoids the problem of the card plate 4 shifting when installing the circuit board.

[0022] like Figures 3 to 5 As shown, the connecting rod 9 is located inside the spring 7 and passes through the interior of the positioning rod 8. When the connecting rod 9 moves, the positioning rod 8 limits the movement of the connecting rod 9, making the movement of the connecting rod 9 more stable and avoiding the problem of deviation when the connecting rod 9 moves, thereby improving the stability of the movement of the connecting rod 9.

[0023] like Figures 3 to 5 As shown, a circular groove is provided inside the card plate 4. The limiting block 6 and the positioning rod 8 are fixedly connected inside the card plate 4. When the positioning block 5 moves, it moves inside the limiting block 6. The limiting block 6 restricts the movement of the positioning block 5, making the movement of the positioning block 5 more stable and avoiding the problem of the positioning block 5 deviating during the movement.

[0024] like Figures 3 to 5 As shown, a groove is provided at the bottom of the card plate 4, and a handle is slidably connected inside the groove. The handle is fixedly connected to the surface of the slider 10. The operator pulls the slider 10 by the handle, so that the operator can operate the card plate 4 to rotate according to their own needs. This allows the operator to adjust the connection method of the circuit board according to actual needs, thereby improving the efficiency of the operator in installing the circuit board.

[0025] like Figures 1 to 3As shown, a baffle 11 is slidably connected to the top of the base 2 on one side of the pressure plate 3. A mounting base 12 is fixedly connected to the bottom of the baffle 11. A screw 13 is slidably connected inside the mounting base 12. A hexagonal nut 14 is threadedly connected to the bottom of the screw 13. The hexagonal nut 14 is fixedly connected inside the base 2. By adjusting the tightness of the screw 13 and the hexagonal nut 14, the angle of the pressure plate can be adjusted. This allows the operator to flip the clamping plate 4 onto the surface of the pressure plate 3. By adjusting the distance between the baffle 11 and the pressure plate 3, the angle formed between the baffle 11 and the pressure plate 3 can be adjusted so that the tilt angle of the clamping plate 4 is suitable for the operator, making it easier for the operator to operate and thus improving the operator's work efficiency in subsequent processes.

[0026] Working principle: During use, the operator needs to install the circuit board inside the card plate 4. Since the card slot of the card plate 4 is horizontal, the operator needs to carefully observe whether the circuit board is installed inside the card plate 4 during normal installation. At this time, the operator pulls the handle, which moves the slider 10. The slider 10 moves the connecting rod 9, which moves the positioning block 5 and squeezes the spring 7. When the positioning block 5 is completely inside the card plate 4, the card plate 4 can rotate because it is no longer limited by the positioning block 5. By adjusting the angle of the card slot of the card plate 4, it is easier to install the circuit board inside the card plate 4. Finally, the card plate 4 with the circuit board installed is reversed to place the circuit board on the plane of the circuit board placement platform 1, thus completing the installation of the circuit board. By rotating the card slot of the card plate 4, it is easier for the operator to install the circuit board inside the card plate 4, thus making the circuit board installation method simpler and improving the installation efficiency of the circuit board.

[0027] Finally, when the operator needs to operate on the back of the circuit board, the clamping plate 3 is flipped over to fit against the baffle 11. The position of the baffle 11 can be adjusted by separating the screw 13 and the hexagonal nut 14. The adjusted baffle 11 is then installed using the screw 13 and the hexagonal nut 14 to achieve the desired angle between the baffle 11 and the clamping plate 3. By adjusting the tightness of the screw 13 and the hexagonal nut 14, the angle of the clamping plate can be adjusted. This allows the operator to flip the clamping plate 4 onto the surface of the clamping plate 3. By adjusting the distance between the baffle 11 and the clamping plate 3, the angle formed between the baffle 11 and the clamping plate 3 can be adjusted to make the tilt angle of the clamping plate 4 suitable for the operator, making it easier for the operator to operate and thus improving the efficiency of the operator in subsequent processes.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
