Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figs. 1-3 In this embodiment of the invention, the composite fabric opening and closing aging performance testing device includes a base 1. Two first supports 2 are symmetrically arranged at one end of the base 1, and a second support frame 5 is fixedly connected to the other end of the base 1. An optical axis 6 is arranged between the second support frame 5 and one of the first supports 2 near the second support frame 5. Both ends of the optical axis 6 are rotatably connected to the first support 2 and the second support frame 5 through bearings. A copper sleeve 7 is provided at one end of the optical axis 6, and a threaded sleeve 8 is connected to the other end of the optical axis 6. Clamping components 4 are provided on one side of both the copper sleeve 7 and the threaded sleeve 8. 4 are on the same horizontal line, and the two sets of clamping components 4 are fixedly connected to the copper sleeve 7 and the threaded sleeve 8 respectively through the connector 9. A cylinder 3 is installed between the two first supports 2. The output end of the cylinder 3 passes through the outer wall of one of the first supports 2, and the output end of the cylinder 3 is fixedly connected to a set of clamping components 4 near the side of the first support 2. One end of the optical axis 6 is provided with a thread 61, and the threaded sleeve 8 is connected to the optical axis 6 through the thread 61. A guide rod 91 is fixedly connected to the outer end of a connector 9 connected to the threaded sleeve 8. One end of the guide rod 91 is slidably connected to the upper end of the second support frame 5.

[0020] In this embodiment: a set of clamping components 4 is driven by a cylinder to move, and the other set of clamping components 4 is an adjustable design. By rotating the optical axis 6, the set of clamping components 4 connected to the threaded sleeve 8 can be forced to move left and right along the length direction of the optical axis 6 to adjust the distance between the two sets of clamping components 4 in the initial state, so as to quickly clamp composite fabrics of different lengths.

[0021] Specifically, when it is necessary to conduct a folding endurance test on the composite fabric, first fix one end of the fabric to a set of clamping components 4 driven by the cylinder 3, then pull the other end of the composite fabric to fully unfold it. Next, by rotating the optical shaft 6, the set of clamping components 4 connected to the threaded sleeve 8 is forced to move left and right along the length direction of the optical shaft 6, and the set of clamping components 4 is moved to a position where the other end of the composite fabric can be clamped. After both ends of the composite fabric are clamped and fixed, the folding endurance test of the composite fabric can be achieved by driving the cylinder 3.

[0022] Please refer to this carefully. Figs. 1-3The outer wall of the guide rod 91 is engraved with a scale.

[0023] In this embodiment: by engraving the scale on the outer wall of the guide rod 91, the distance between the two sets of clamping assemblies can be recorded or approximately understood, and in addition, the guide rod 91 also serves as a guide rod.

[0024] Please refer to Fig. 3 The clamping assembly 4 comprises a fixed block 401, which is in the shape of a "Fang" character. The inner side of the fixed block 401 is provided with a pressing block 402. One end of the pressing block 402 is fixedly connected with a pull rod 403, which penetrates through the outer wall of the fixed block 401. The fixed block 401 and the pull rod 403 are movably connected. The outer wall of the pull rod 403 is sleeved with a spring 404, which is located between the pressing block 402 and the inner wall of the fixed block 401. The two side walls of the pressing block 402 and the fixed block 401 are arranged in parallel, and one end of the pressing block 402 is slidably connected to the outer edge of the fixed block 401.

[0025] In this embodiment: by pulling the pull rod 403 to drive the pressing block 402 to slide along the outer edge of the fixed block 401, the pressing block 402 and the side wall of the fixed block 401 are moved away, and the spring 404 is compressed. Then, one end of the composite fabric is placed between the pressing block 402 and the fixed block 401. After releasing the pull rod 403, the pressing block 402 returns to the initial position under the restoring force of the spring 404. At this time, one end of the composite fabric is firmly clamped and fixed.

[0026] The existing clamping mechanism in the durability tester mostly uses bolts to tighten two clamping plates to hold the fabric. The operation during clamping is relatively cumbersome, especially after the bolt slips, it cannot be used. Therefore, by setting the clamping assembly 4, the fabric can be quickly clamped or released, the operation is convenient, the clamping force is moderate, and the folding test is not affected.

[0027] Please refer to Figs. 1-3 The clamping assembly 4 further comprises a first tooth groove 405, which is opened on the end face of the pressing block 402 away from the pull rod 403. A second tooth groove 406 is opened on one side wall of the fixed block 401, which matches the first tooth groove 405.

[0028] In this embodiment: the first tooth groove 405 is also opened on the pressing block 402, and the second tooth groove 406 matching the pressing block 402 is also opened on the inner wall of the fixed block 401 facing the pressing block 402. This effectively improves the friction between the fixed block 401 and the pressing block 402, and prevents the composite fabric from falling off during clamping.

[0029] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
