Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, and more specifically relates to a circuit board pressing and positioning device for an electric rice cooker. Background Art

[0002] The heating circuit board of the rice cooker is the core component that controls the heating function. The AC signal is input through the power supply. After rectification, voltage stabilization and filtering, the current passes through the heating coil to generate heat. When making the circuit board of the rice cooker, a pressing and positioning device is required. The circuit board can be positioned during the pressing process to prevent the circuit board from shifting during the pressing process.

[0003] When positioning the rice cooker circuit board, the existing pressing and positioning device can only limit the two sides of the circuit board to position the circuit board. However, when the circuit board is in the pressing process, the circuit board may still shift in the directions of the other two sides, which will cause the circuit board to fail to press, reducing the practicality of the positioning device.

[0006] By setting two auxiliary blocks, under the action of the threaded rod, when the two clamps limit the two sides of the circuit board, the threaded rod is rotated, the threaded rod will drive the slider connected to the screw hole block to slide on the inner wall of the slide groove, and the slider will drive the auxiliary blocks to move synchronously until one side of the two auxiliary blocks respectively abuts against the other two sides of the circuit board, so that the circuit board can be positioned in four directions, which is beneficial to prevent the circuit board from shifting, facilitates the normal pressing of the circuit board, and effectively improves the practicability of the positioning device.

[0010] According to the electric rice cooker circuit board pressing and positioning device described in the first embodiment of the utility model, a limiting block is provided on one side of the screw hole block, and the inner wall of the limiting block is threadedly connected to the outer surface of the threaded rod. By providing the limiting block and rotating the limiting block so that the limiting block moves on the outer surface of the threaded rod until one side of the limiting block abuts against one side of the screw hole block, one side of the auxiliary block can be limited, which is beneficial to prevent the auxiliary block from loosening the clamping of the circuit board.
