All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

With reference to fig. 1 to 3, in an embodiment, the elastomer hardness testing apparatus of the present application includes: the hardness tester 1 for elastomer test and the guide rail mechanism. The guide rail mechanism is used for assisting the hardness tester 1 for testing the elastic body to test the hardness of the elastic body 6 with the convex top surface 6A with a preset radian. The elastic body 6 is used to assist the flexible inner screen to adhere to the curved glass, and has a convex top surface with a high middle part and two low sides, such as the elastic body disclosed in patent application CN 201920132145.5.

Referring to fig. 1 to 3, the guide rail mechanism includes: a mounting seat 2 and a guide rail seat 3. The mounting seat 2 is capable of holding the elastomer test durometer 1 and limiting the radial movement of its test head 1A to be close to the top surface 6A of the elastomer 6.

The durometer 1 for elastomer testing may be a conventional hand-held durometer, and is not described in detail. The mount pad 2 is a U-shaped structure clamped on the guide rail portion 3A, and includes: a support part 2A for supporting the hardness tester 1 for elastomer test, and a sliding contact part 2B in sliding fit with the guide rail part 3A. The rail housing 3 includes: a rail portion 3A and a base portion 3B. The guide rail portion 3A is slidably engaged with the mounting base 2 and defines the movement of the mounting base 2 within a predetermined arc range, as will be described in further detail below.

The guide rail portion 3A has a test head moving path S4 penetrating in the radial direction and extending in a predetermined arc, the holder portion 2A has a through hole (not shown) through which the test head 1A enters the test head moving path S4, the guide rail portion 3A has a guide groove S2 extending in a predetermined arc, the sliding portion 2B is connected to a guide pin (not shown) slidably disposed in the guide groove S2, and the guide pin passes through a pin hole S1 of the sliding portion 2B and is fitted into the guide groove S2. The durometer 1 for elastomer test may be fixed to the support portion 2A by a fastening screw or the like. The two base portions 3B are provided on both sides of the guide rail portion 3A in the circumferential direction, respectively, and the base portions 3B support the guide rail portion 3A and define a housing space M for housing the elastic body 6 below the guide rail portion 3A. The mounting base 2 has a position indicating part L1, the guide rail part 3A has arc indicating parts L2 distributed at intervals in a preset arc range, and both the position indicating part L1 and the arc indicating parts L2 are strip-shaped notches. When the mounting base 2 moves relative to the guide rail portion 3A, the position indicating portion L1 moves between the different radian marking portions L2 correspondingly, and then the moving radian of the mounting base 2 is marked, so as to indirectly position the moving position of the durometer 1 for testing the elastic body relative to the elastic body.
