[0018] The specific embodiments described herein are only used to explain the technical solution of this patent, rather than to limit the disclosed technical solution. It should also be noted that, for the convenience of description, only the parts related to the technical solution of this application are shown in the drawings, rather than all structures.

[0019] Before discussing the exemplary embodiments in more detail, it should be mentioned that the structures of the device components and / or modules themselves mentioned in the embodiments, if not described in detail, are understandable to those skilled in the art based on the existing public technology or commercially available products.

[0020] like Figure 1 As shown, the automobile sealing strip wear resistance test device provided in this embodiment includes a motor 1, an adjusting nut 2, a screw 3, a fixing nut 4, a support platform 5, a first movable plate 6, a second movable plate 7, a slide rail 8, an electric screw 9 and a PLC control cabinet 10. The output shaft of the motor 1 is connected with the adjusting nut 2, the nut 2 is sleeved on the top of the screw 3, and the fixing nut 4 is arranged on the table surface of the support platform 5; the middle part of the screw 3 is vertically arranged in the fixing nut 4, and the bottom of the screw 3 is connected with the first movable plate 6; the left and right ends of the second movable plate 7 are arranged on the slide rail 8, and the bottom surface of the second movable plate 7 is connected with the movable nut of the electric screw 9; the PLC control cabinet 10 is used to control the motors of the motor 1 and the electric screw 9.
