Description

Technical Field

[0001] The present invention relates to elastomer testing technology, and more specifically, to a guide rail mechanism for durometer testing and an elastomer hardness testing device. Background Art

[0002] Combined with the content disclosed in patent application CN201920132145.5, a flexible inner screen is usually attached to a curved glass by means of an elastomer, and this kind of elastomer has an arc-shaped top surface that is high in the middle and low on both sides. To ensure the bonding quality, it is necessary to ensure that the hardness distribution at the top of the elastomer is relatively uniform. In the existing method, testers usually use a durometer for elastomer testing, and need to manually move the durometer according to experience to measure the hardness at different positions, and its operability is also poor. In view of this, this application is specifically proposed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a guide rail mechanism for durometer testing to solve the problem of poor operability in manually moving the durometer to test different positions of the elastomer.

[0004] To solve the above technical problem, the present invention provides a guide rail mechanism for durometer testing, which is used to assist a durometer for elastomer testing to test the hardness of an elastomer with a convex top surface having a preset radian. The guide rail mechanism includes: a mounting seat and a guide rail seat; the mounting seat can support the durometer for elastomer testing and limit the radial movement of its test head to approach the top surface of the elastomer; the guide rail seat includes: a guide rail portion and a base portion; the guide rail portion is slidably engaged with the mounting seat and limits the movement of the mounting seat within a preset radian range; the base portion supports the guide rail portion and defines a receiving space for accommodating the elastomer below the guide rail portion.

[0005] Preferably, the mounting seat includes: a supporting portion for supporting the durometer for elastomer testing and a sliding connection portion slidably engaged with the guide rail portion.

[0006] Preferably, the guide rail portion has a test head movement channel that penetrates radially and extends a preset radian, and the supporting portion has a through hole for the test head to pass through and enter the test head movement channel.

[0007] Preferably, the guide rail portion has a guiding groove extending a preset radian, and the sliding connection portion is connected with a guiding pin slidably arranged in the guiding groove.

[0008] Preferably, the guide rail portion has radian marking portions spaced apart within a preset radian range, and the mounting seat has a position indicating portion; when the mounting seat moves relative to the guide rail portion, the position indicating portion moves correspondingly between different radian marking portions.

[0009] Preferably, there are two base parts, which are respectively arranged on both sides of the guide rail part along the circumferential direction.

[0010] Preferably, the guide rail mechanism further includes: a support plate for supporting the elastic body, and the base part is installed on the support plate.

[0011] Preferably, the guide rail mechanism further includes: a position limiting member for limiting the position of the elastic body in the accommodation space.

[0013] This application further provides an elastic body hardness testing device, including: the guide rail mechanism described in any one of the foregoing items, and a hardness meter for testing the elastic body installed on the mounting seat of the guide rail mechanism.

[0014] By adopting the above technical solutions, the present invention can achieve the following technical effects:

[0015] 1. By adopting the guide rail mechanism of this application, when the hardness meter for testing the elastic body is installed on the mounting seat, its test head can be limited to move radially, which can ensure accurate measurement. At the same time, the mounting seat can move relative to the guide rail part within a preset radian range, so that the hardness meter can sequentially test the hardness of different positions of the elastic body, and the operability is better.

[0016] 2. Through the radian marking part and the position indicating part, the moving amplitude of the mounting seat can be controlled more precisely. Description of the Drawings

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention.

[0021] In conjunction with Figures 1 to 3 , in one embodiment, the elastomer hardness testing device of the present application includes: a hardness tester 1 for elastomer testing and a guide rail mechanism. The guide rail mechanism is used to assist the hardness tester 1 for elastomer testing to test the hardness of the elastomer 6 having a convex top surface 6A with a preset curvature. The elastomer 6 is used to assist the flexible inner screen to be attached to the curved glass, and it has a convex top surface that is high in the middle and low on both sides. For example, it is the elastomer disclosed in the patent application CN201920132145.5.

[0022] In conjunction with Figures 1 to 3 , the guide rail mechanism includes: a mounting base 2 and a guide rail base 3. The mounting base 2 can support the hardness tester 1 for elastomer testing and limit the movement of its test head 1A in the radial direction to approach the top surface 6A of the elastomer 6.

[0023] The hardness tester 1 for elastomer testing can be a common handheld hardness tester, which will not be elaborated here. The mounting base 2 is a U-shaped structure clamped on the guide rail part 3A, and it includes: a supporting part 2A for supporting the hardness tester 1 for elastomer testing and a sliding part 2B slidably engaged with the guide rail part 3A. The guide rail base 3 includes: a guide rail part 3A and a base part 3B. The guide rail part 3A and the mounting base 2 are slidably engaged, and limit the movement of the mounting base 2 within a preset curvature range, which will be further described in detail below.

[0024] The guide rail part 3A has a test head movement channel S4 that penetrates radially and extends a preset radian. The supporting part 2A has a through hole (not shown in the figure) for the test head 1A to pass through and enter the test head movement channel S4. The guide rail part 3A has a guide groove S2 that extends a preset radian. The sliding connection part 2B is connected with a guide pin (not shown in the figure) that is slidably arranged in the guide groove S2. The guide pin passes through the pin hole S1 on the sliding connection part 2B and is embedded in the guide groove S2. The hardness tester 1 for elastomer testing can be fixed on the supporting part 2A through structures such as fastening screws. There are two base parts 3B, which are respectively arranged on both sides of the guide rail part 3A along the circumferential direction. The base parts 3B support the guide rail part 3A and define a accommodation space M for accommodating the elastomer 6 under the guide rail part 3A. The mounting base 2 has a position indicating part L1, and the guide rail part 3A has radian marking parts L2 that are spaced apart within a preset radian range. Both the position indicating part L1 and the radian marking parts L2 are strip-shaped grooves. When the mounting base 2 moves relative to the guide rail part 3A, the position indicating part L1 moves correspondingly between different radian marking parts L2, thereby marking the movement radian of the mounting base 2 and indirectly positioning the movement position of the hardness tester 1 for elastomer testing relative to the elastomer.

[0025] Combined with Figure 3 , in this embodiment, the guide rail mechanism further includes a supporting plate 4 for supporting the elastomer. The base part 3B is installed on the supporting plate 4. The base part 3B has a screw through hole S3, and thus the base part 3B can be fixed on the supporting plate 4 through screws. The guide rail mechanism further includes a position limiting member 5 for limiting the position of the elastomer in the accommodation space M. The position limiting member 5 is a strip-shaped structure and can be detachably installed on the supporting plate 4. The position limiting member 5 can be detachably installed on the supporting plate, which is convenient for selecting a suitable position limiting member according to the size of different elastomers 6. Combined with Figure 3 , during the test, first, the left side 6B of the elastomer 6 is abutted against the position limiting member 5. The tester slides the hardness tester 1 for elastomer testing and the mounting base 2 on the guide rail part 3A to sequentially perform hardness tests on different positions of the arc-shaped top surface of the elastomer 6. And after completing the hardness test at a certain position, the elastomer 6 can be axially displaced to test the hardness at another position.

[0026] The above is an embodiment of the present application. However, it is easy to understand that the present application is not limited to the above implementation manner. In another embodiment, the mounting base and the guide rail part can adopt other matching methods, as long as it is ensured that the guide rail part can limit the movement of the mounting base within a preset radian range. In another embodiment, the position limiting member can be installed not on the supporting plate but on the base part 3B. In another embodiment, the position limiting member 5 may not be a strip-shaped structure but a discontinuous limiting member.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
