[0026] The utility model provides Figure 1-6 A sealant fatigue test device shown in the figure comprises a bottom plate 1, wherein the four corners of the bottom plate 1 are fixedly connected to a top plate 2 via four columns 3, and the top wall of the bottom plate 1 is fixedly connected to a processing base 4, and a placement groove 5 is reserved inside the processing base 4, the top wall of the processing base 4 is fixedly connected to an annular side plate 1 6 and an annular side plate 2 7 in sequence, and an annular channel 8 is reserved between the annular side plate 1 6 and the annular side plate 2 7, a cylinder 9 is embedded and installed inside the top plate 2, and a circular plate 10 is fixedly connected to the output end of the cylinder 9, and a sealing side plate 11 is fixedly connected to the bottom of the circular plate 10, and the lower end of the sealing side plate 11 matches the plug-in groove 14, and the plug-in groove 14 is preset inside the processing base 4, a fixing rod 15 is fixedly connected to the bottom of the circular plate 10, and a hammer block 16 is fixedly connected to the lower end of the fixing rod 15.

[0027] The surfaces of the annular side plate 1 6 and the annular side plate 2 7 are both smooth surfaces, and the annular channel 8 left between the annular side plate 1 6 and the annular side plate 2 7 is movably connected to the sealing side plate 11, and the arc-shaped outer walls on both sides of the sealing side plate 11 are in contact with and slidably connected to the outer walls of the annular side plate 1 6 and the annular side plate 2 7, ensuring that a closed test space can be formed between the annular side plate 1 6, the annular side plate 2 7 and the sealing side plate 11 to prevent samples from jumping out and accidentally injuring staff during the test.

[0028] A square limit block 12 is fixedly connected to one side wall of the circular plate 10 away from the sealing side plate 11, and the limit block 12 moves inside the strip limit groove 13 reserved inside the annular side plate 2 7, and the side wall of the limit block 12 is in contact with the inner wall of the limit groove 13 and is connected by sliding up and down, thereby ensuring the stability of the lifting and lowering movement of the sealing side plate 11 and ensuring that the closed test space between the annular side plate 1 6, the annular side plate 2 7 and the sealing side plate 11 is smoothly formed.

[0029] The height of the sealing side plate 11 is one third of the distance between the bottom plate 1 and the top plate 2 , and a gap is left in the sealing side plate 11 to facilitate the movement of the sealing side plate 11 without affecting the placement of the sample.

[0030] The limit block 12 moves up and down inside the annular channel 8, and the end wall of the limit block 12 close to the annular side plate 6 fits with the curved wall of the annular side plate 6, and the end wall of the limit block 12 is slidably connected to the curved wall of the annular side plate 6 up and down, ensuring the stability of the lifting and lowering movement of the sealing side plate 11, and ensuring the smooth formation of the closed test space between the annular side plate 16, the annular side plate 2 7 and the sealing side plate 11.

[0031] The plug-in slot 14 is set throughout the inside of the processing base 4, and the inner wall of the plug-in slot 14 is in contact with the outer wall of the sealing side plate 11 and is slidably connected up and down, which increases the space for the sealing side plate 11 to move, ensuring that there is more room for movement when the hammer block 16 performs an up and down hammer test.

[0032] Working principle: When using a sealant fatigue test device, first place the sealant sample to be tested in the reserved placement groove 5 in the processing platform 4, and then start the cylinder 9. The cylinder 9 moves downward to drive the circular plate 10 fixedly connected to the end of the cylinder 9, so that the circular plate 10 moves downward synchronously, and the sealing side plate 11 fixedly connected to the side wall of the circular plate 10 moves downward synchronously with the movement of the circular plate 10. The lower end of the sealing side plate 11 is then matched with the plug-in groove 14, and at the same time, the limit block 12 fixedly connected to the side wall of the circular plate 10 is located at the second annular side plate 7. The circular plate 10 moves in the reserved limit groove 13 to ensure that the sealing side plate 11 is accurately matched with the plug-in groove 14. At this time, a closed space is formed between the sealing side plate 11, the annular side plate 16 and the annular side plate 2 7. During the descending process of the circular plate 10, the hammer block 16 fixedly connected to the circular plate 10 by the fixing rod 15 moves downward synchronously with the sealant sample placed in the groove 5 for hammering test. At this time, a closed space is formed between the sealing side plate 11, the annular side plate 16 and the annular side plate 2 7, which prevents the sample from jumping out due to improper operation.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
