DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the utility model are only for the convenience of clear description, not to limit the scope of the utility model that can be implemented, and the change or adjustment of the relative relationship is also regarded as the scope of the utility model that can be implemented without substantial change of the technical content.

[0023] Referring to Figures 1-4 A testing device for FPC flexible circuit board, including mounting table 1 and two electric push rods slidingly arranged on mounting table 1, when the two electric push rods are electrified and work, the driving end of the two electric push rods moves to bend and test the FPC flexible circuit board, T-shaped slot is formed on mounting table 1, sliding block 11 and two bending frames 9 are slidingly connected in the T-shaped slot, bottom plate 8 is fixedly connected on each bending frame 9, reciprocating screw rod 18 is rotatably connected in the T-shaped slot, sliding block 11 and reciprocating screw rod 18 are screw-connected, each bending frame 9 is connected with sliding block 11 through pull rope 14, roller 15 is fixedly connected on reciprocating screw rod 18, sliding assembly is arranged on each bending frame 9, fixed seat 2 is fixedly connected on mounting table 1, and locking assembly is arranged on fixed seat 2.

[0024] Each sliding assembly comprises a pressing plate 6 slidingly mounted on the bending frame 9, and the bending rod 7 is fixedly connected to the pressing plate 6; the locking assembly comprises the mountain-shaped rod 4 mounted on the fixed seat 2 through the first spring 17, and the limiting rod 5 is fixedly connected to the mountain-shaped rod 4; the sawtooth strip 16 is slidingly connected to the fixed seat 2; the mountain-shaped rod 4 is pressed downward, and the first spring 17 is deformed due to the fixed connection of one end of the first spring 17 with the mountain-shaped rod 4 and the fixed connection of the other end of the first spring 17 with the fixed seat 2, until the FPC flexible circuit board is compressed between the pressing plate 6 and the bottom plate 8; then the sawtooth strip 16 is pushed to slide relative to the fixed seat 2, until one end of the limiting rod 5 is clamped between two adjacent sawteeth, so that the pressing plate 6 is prevented from moving randomly.

[0025] Each bending rod 7 is fixedly mounted with the telescopic rod 3, and the telescopic end of each telescopic rod 3 is fixedly connected with the mountain-shaped rod 4; during the movement of the bending frame 9 along the T-shaped groove, the bending rod 7 and the pressing plate 6 move simultaneously, and the telescopic rod 3 is deformed simultaneously; the first fixed plate 13 and the two second fixed plates 12 are fixedly connected in the T-shaped groove; the through hole for connecting the pull rope 14 is formed in each first fixed plate 13 and second fixed plate 12; and the first fixed plate 13 and the second fixed plate 12 can limit the movement track of the pull rope 14.

[0026] The second spring 10 is fixedly connected to the inner wall of the T-shaped groove, and the two second springs 10 are fixedly connected with the two bending frames 9, respectively; the roller 15 is stepped on, so that the reciprocating screw rod 18 and the mounting table 1 rotate relative to each other, and the sliding block 11 moves along the reciprocating screw rod 18 and slides closely to the inner wall of the T-shaped groove; under the transmission action of the pull rope 14, the two bending frames 9 slide along the T-shaped groove, and the two second springs 10 are deformed simultaneously.

[0027] In this invention, during use, stepping on the roller 15 causes the reciprocating screw 18 and the mounting platform 1 to rotate relative to each other. The slider 11 then moves along the reciprocating screw 18 and slides tightly against the inner wall of the T-slot. Since the two ends of each inelastic pull rope 14 are fixedly connected to the slider 11 and the corresponding bending frame 9, and each inelastic pull rope 14 passes through the through holes on the first fixing plate 13 and the corresponding second fixing plate 12, under the transmission action of the pull rope 14, the two bending frames 9 slide along the T-slot, thereby adjusting the distance between the two bending frames 9 and placing the FPC flexible circuit board on both sides. After pressing the base plate 8, press down on the mountain-shaped rod 4. Since one end of the first spring 17 is fixedly connected to the mountain-shaped rod 4 and the other end is fixedly connected to the fixing seat 2, the first spring 17 deforms until the FPC flexible circuit board is pressed between the pressure plate 6 and the base plate 8. Then push the serrated strip 16 to make it slide relative to the fixing seat 2 until one end of the limit rod 5 is stuck between two adjacent serrations, which can prevent the pressure plate 6 from moving at will. The distance between the two base plates 8 can be adjusted by simply rotating the roller 15, and there is no need to turn the knob to lock it. The operation is relatively simple and quick, which is conducive to the rapid use of the testing device.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
