The fixing components provide a gas source as a power for sealing and fixing through an air supply component. The present invention is scientific and reasonable, safe and convenient to use. The present invention is provided with a fixing component and an air supply component, and the air supply component is used to supply air to the fixing component, so that the fixing component can fix the leak-proof water pipe more firmly. At the same time, under the action of the curved surface and the deformation part, the fixed sealing performance of the end of the leak-proof water pipe is higher, which greatly improves the detection efficiency of the leak-proof water pipe.

[0004] Existing floating oil seal performance testing equipment is unable to conduct multi-dimensional testing during the testing process. Oil seal performance typically involves multiple dimensions, such as sealing, wear resistance, temperature resistance, corrosion resistance, and stability under different operating conditions. If the testing equipment can only test a single or a few dimensions, the evaluation of the oil seal performance will be very one-sided and may not fully reflect the true performance of the oil seal. To this end, we have proposed a floating oil seal performance testing device. Utility Model Content
