Among them, the cushioning test is particularly important. It is used to test the cushioning performance of TPO materials. Some traditional testing devices are not vivid enough, and the data measured by the machine is relatively slow, which consumes more time when comparing data. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A buffer testing device for TPO material comprises a mounting platform 1, a socket 3 is symmetrically arranged on the upper surface of the mounting platform 1, a placement rack 2 is inserted and installed on the socket 3, a TPO coil 4 is placed on the upper surface of the placement rack 2, and a pressing mechanism 5 is symmetrically arranged on the upper surface of the mounting platform 1 and on both sides of the placement rack 2;

[0023] The pressing mechanism 5 includes a mounting frame 51, on the upper plate of which a slide rod 53 is movably provided, and the bottom end of the slide rod 53 is fixedly connected with a pressing plate 52, which can be pressed on the upper surface of the placement frame 2, and a screw 54 is provided on the upper surface of the pressing plate 52 and on one side of the slide rod 53.

[0024] A through hole is formed on the upper plate of the mounting frame 51 , and a screw rod 54 is arranged at the through hole. The diameter of the through hole is larger than the major diameter of the screw rod 54 . The through hole allows the screw rod 54 to move freely on the mounting frame 51 .

[0025] In addition, a plurality of nuts 55 are screwed onto the screw rod 54 , and the nuts 55 are located on the upper and lower sides of the upper end plate of the mounting frame 51 . The nuts 55 can be screwed onto the two side surfaces of the mounting frame 51 , thereby fixing the screw rod 54 .

[0026] A silicone pad 10 is attached to the surface of the pressing plate 52 facing the placement rack 2 , and the pressing plate 52 cooperates with the silicone pad 10 to press the TPO coil 4 , thereby pressing the TPO coil 4 without damaging the TPO coil 4 .

[0027] Moreover, a fixing frame 9 is symmetrically arranged on the upper surface of the mounting platform 1 and on both sides of the pressing mechanism 5, and an observation tube 6 is arranged between the upper ends of the fixing frames 9 on both sides. The observation tube 6 is made of a transparent material, and the observation tube 6 is made of a material including but not limited to acrylic material, so that the observer can observe the rebound of the elastic ball 8.

[0028] In addition, an elastic ball 8 is placed in the body of the observation tube 6, and a scale plate 7 is arranged between the fixing frames 9 on both sides. The scale plate 7 is located at the rear side of the observation tube 6. The scale plate 7 is convenient for the observer to record the height of the elastic ball 8 after rebounding.

[0029] Among them, an opening 21 is opened in the middle of the upper surface of the placement rack 2, and plug-in blocks 22 are set at the bottom ends of both sides of the placement rack 2. The plug-in blocks 22 can be inserted and installed in the socket 3. The placement rack 2 cooperates with the plug-in blocks 22 and the socket 3, making the installation and disassembly method more convenient.

[0030] In this embodiment, when testing the buffering performance of the TPO material, first insert the plug 22 of the placement rack 2 into the socket 3, install the placement rack 2 on the mounting table 1, then attach the TPO coil 4 to the upper surface of the placement rack 2, smooth it, and then operate the pressing mechanism 5 to press the TPO coil 4.

[0031] First, the two nuts 55 are screwed in so that the screw rod 54 can move freely up and down on the mounting frame 51, and cooperate with the sliding rod 53 on one side that can move linearly, so that the pressing plate 52 can be adjusted in height at this time, so that the pressing plate 52 presses the TPO coil 4, and cooperates with the silicone pad 10 to play a protective role, and then the nuts 55 are tightened on the upper and lower sides of the mounting frame 51, so that the screw rod 54 can be fixed, thereby fixing the pressing plate 52, so that the smoothed and straightened TPO coil 4 is effectively pressed and fixed, thereby ensuring that the buffering performance of the TPO coil can be better reflected during the buffering test.

[0032] After the TPO coil 4 is installed, the elastic ball 8 can be used for testing. The elastic ball 8 is held at a fixed height at the upper end of the observation tube 6, and then the hand is released to allow the elastic ball 8 to fall freely, so that the elastic ball 8 falls on the TPO coil 4. The design of the opening 21 ensures that the elastic ball 8 always falls on the TPO coil 4. This is because the rebound is generated by the buffering performance of the TPO coil 4 itself. After the elastic ball 8 falls on the TPO coil 4, it will rebound in the observation tube 6. The tester can observe the rebound height of the elastic ball 8 through the observation tube 6 and record it with the help of the scale plate 7.

[0033] After the test, the nuts 55 on both sides are loosened and the TPO coil 4 is pulled down so that the elastic ball 8 can fall from the opening 21. The operator then takes the elastic ball 8 out from under the rack 2 to facilitate the next test, and then replaces a different TPO coil 4 for testing.

[0034] By recording the rebound height of the elastic ball 8 falling on the TPO coil 4 of different materials, and then recording the height of the first rebound, the smaller the rebound height, the better the cushioning effect of the TPO coil 4.

[0035] In the utility model, the placement rack 2 is provided so that the TPO coil 4 can be effectively placed, and the pressing mechanism 5 on both sides can be used to firmly press the TPO coil 4 on the upper surface to ensure the accuracy of the test, and the observation tube 6 is used to observe the rebound height of the elastic ball 8, and the scale plate 7 is used to record the rebound height of the elastic ball 8 falling on TPO coils 4 of different materials, so that the buffering performance of the TPO coil 4 can be tested. The device can observe the test process more intuitively through the elastic ball 8, and when comparing data, it only needs to compare the rebound height of the elastic ball 8, and it is more convenient to replace the TPO coil 4, so as to more quickly obtain the TPO coil 4 with better buffering performance.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
