[0038] Further, in the above structure, the first semicircular arc plate 21 is provided with an adjusting channel 27 capable of accommodating an adjusting threaded rod 242, and the adjusting threaded rod 242 is provided with an internal hexagonal adjusting hole 246 at one end arranged in the adjusting channel 27.

[0039] In the structure of the guide mechanism 23, the connecting block 231 is connected to the end of one end of the first semicircular arc plate 21. Specifically, the guide mechanism 23 is provided with two groups, and the connecting blocks 231 of the two groups of guide mechanisms 23 are respectively connected to the ends of one end of the first semicircular arc plate 21. The guide sleeve 233 is fixedly sleeved in the connecting block 231 to provide a sliding track for the guide sliding rod 232. The guide sliding rod 232 is slidably arranged in the guide sleeve 233 and can freely slide in the guide sleeve 233. The mounting table 234 is connected to the end of the guide sliding rod 232 away from the first semicircular arc plate 21 and is connected with the side wall of the concave side of the second semicircular arc plate 22 through the mounting table 234, thereby realizing the connection and guidance between the first semicircular arc plate 21 and the second semicircular arc plate 22.

[0040] The guiding mechanism 23 plays a guiding and stabilizing role in the paper diaper waist circumference elasticity testing device, and when the adjusting mechanism 24 adjusts the distance between the first semicircular arc plate 21 and the second semicircular arc plate 22, the guiding mechanism 23 ensures that the first semicircular arc plate 21 can be stably moved, avoiding shaking and errors in the testing process.

[0041] Specifically, when the adjusting threaded rod 242 is rotated, it drives the first fixed block 243 and the second fixed block 244 to move, thereby changing the distance between the first semicircular arc plate 21 and the second semicircular arc plate 22. In this process, the guiding sleeve 233 and the guiding slide rod 232 of the guiding mechanism 23 play a guiding role, and the guiding slide rod 232 slides in the guiding sleeve 233, ensuring that the first semicircular arc plate 21 can move along the predetermined trajectory, avoiding shaking and errors, thereby improving the testing accuracy and stability.

[0042] As one of the preferred embodiments of the utility model, Figure 2 and Figure 3 As shown in the drawings, the adjusting threaded rod 242 is provided with a connecting plate 245, one end of the connecting plate 245 is threadedly connected with the adjusting threaded rod 242, and the other end of the connecting plate 245 is connected with the connecting block 231 located on the left side of the adjusting threaded rod 242.

[0043] One end of the connecting plate 245 is threadedly connected with the adjusting threaded rod 242, and the other end is connected with the connecting block 231 located on the left side of the adjusting threaded rod 242. The surface of the adjusting threaded rod 242 is provided with external threads, so that the connecting plate 245 can move with the rotation of the adjusting threaded rod 242. Specifically, when it is necessary to adjust the distance between the first semicircular arc plate 21 and the second semicircular arc plate 22, the adjusting threaded rod 242 can be rotated to achieve the adjustment. Since the adjusting threaded rod 242 is threadedly connected with the connecting plate 245, rotating the adjusting threaded rod 242 will cause the connecting plate 245 to move along the axial direction of the adjusting threaded rod 242. This movement will be further transmitted to the first semicircular arc plate 21 through the connecting block 231, thereby changing the distance between the first semicircular arc plate 21 and the second semicircular arc plate 22. The other end of the adjusting threaded rod 242 is located in the adjusting channel 27 of the first semicircular arc plate 21 and is provided with an internal hexagonal adjusting hole 246, which facilitates the rotation of the internal hexagonal wrench. At the same time, since the connecting plate 245 is threadedly connected with the adjusting threaded rod 242, this connection has self-locking property, which can ensure that the distance between the first semicircular arc plate 21 and the second semicircular arc plate 22 remains stable after adjustment.

[0044] As one of the preferred embodiments of the utility model, as shown in Figure 2 and Figure 3 The right side of the adjusting threaded rod 242 is provided with a limiting rod 26, the limiting rod 26 is sequentially arranged in the connecting block 231 and the mounting table 234 inside the right side of the adjusting threaded rod 242, the end of the limiting rod 26 close to the pressure sensor 25 is connected with the side wall of the inner concave side of the second semicircular arc plate 22, the connecting block 231 is slidingly connected with the limiting rod 26, and the mounting table 234 is fixedly connected with the limiting rod 26.

[0045] During the elastic force test, when the adjusting mechanism 24 adjusts the distance between the first semicircular arc plate 21 and the second semicircular arc plate 22, the guiding mechanism 23 needs to be kept stable to ensure the accuracy of the test, the limiting rod 26 can effectively prevent the guiding sleeve 233 from being separated from the guiding slide rod 232, so that the first semicircular arc plate 21 is prevented from losing the guidance during the movement, in addition, the limiting rod 26 not only connects one of the guiding mechanisms 23 between the first semicircular arc plate 21 and the second semicircular arc plate 22, but also is fixedly connected on the mounting table 234 and the second semicircular arc plate 22, so that the structural stability of the whole elastic force test mechanism 2 is enhanced.

[0046] The above is only the preferred embodiment of the utility model, it should be pointed out that for the ordinary skilled person in the art, on the premise of not departing from the principle of the utility model, a number of improvements and refinements can be made, these improvements and refinements should also be regarded as the protection scope of the utility model.
