DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Embodiment: A mobile phone touch screen bending test device, such as Figure 1-Figure 3 As shown, it includes a base 1, a first mounting frame 2, a second mounting frame 201, a limiting rod 3, a support rod 4, a clamp 5, an elastic member 6, a connecting block 7, a stepping motor 10 and a mounting plate 11. The first mounting frame 2 is connected to the base 1 by bolts, and the left part of the first mounting frame 2 is symmetrically connected to the limiting rod 3 by bolts. The limiting rod 3 is a round rod wrapped with a rubber sleeve on the periphery. The support rod 4 is divided into two groups, each group includes two support rods 4, and the two groups of support rods 4 are symmetrically welded in the first mounting frame 2. Clamps 5 are symmetrically provided on the upper and lower sides of each group of support rods 4. The lower clamp 5 is fixedly connected by bolts, and the upper clamp 5 is connected to the support The support rod 4 is connected in an up-and-down sliding manner, and an elastic member 6 is connected between the upper clamp 5 and the lower clamp 5 via a spring seat, and connecting blocks 7 are connected to the front and rear sides of the clamp 5. A stepper motor 10 is installed on the base 1, and the stepper motor 10 is located behind the first mounting frame 2. A mounting plate 11 is connected to the output shaft of the stepper motor 10 via a coupling, and a second mounting frame 201 is connected to the mounting plate 11 via bolts. Except that the limiting rod 3 is not connected to the second mounting frame 201, other structures are the same as those on the first mounting frame 2, and the bottom surface of the second mounting frame 201 and the bottom surface of the first mounting frame 2 are located on the same horizontal plane.

[0019] like Figure 1-Figure 3 As shown, it also includes a wedge rod 8, a pull rod 9, a fan 12, an air guide tube 13 and a rubber pad. The first mounting frame 2 and the second mounting frame 201 are both slidably connected with the wedge rod 8 through a slide rail. The wedge rod 8 is located between the connecting blocks 7, and the wedge rod 8 is in contact with the connecting blocks 7. The wedge rod 8 is connected with a pull rod 9; the base 1 is connected to the fan 12, and the left side of the fan 12 is connected to the air guide tube 13. The number of the fan 12 and the air guide tube 13 is at least two, and the air outlet of the air guide tube 13 is located below the limit rod 3; a rubber pad is provided on the opposite side of the clamp 5.

[0020] When the device is to be used, the product to be tested is first placed between the clamps 5, and the midline of the product length is aligned with the axis of the limit rod 3. Then, the pull rod 9 is pulled, the wedge rod 8 on the first mounting frame 2 is moved to the right, and the wedge rod 8 on the second mounting frame 201 is moved to the left, so that the wedge rod 8 does not contact the connecting block 7.
