[0002] At present, when a washing machine with a washer and dryer is connected to a faucet through a water pipe, a joint is often required, and the existing faucet interfaces are mainly divided into two types. One is a threaded joint, which is a common type of joint, usually consisting of a water inlet pipe and a washing machine faucet. The end of the water inlet pipe has a thread and can be connected to the faucet. It is characterized by a stable connection and not easy to loosen, but it is troublesome to disassemble and assemble. The other is a quick joint, which consists of a water inlet pipe and a quick joint connector. The quick joint connector has a tension spring structure inside, so the quick joint is also called a tension nut clamp joint, which is clamped with the faucet through a spring tension structure and has the characteristic of quick disassembly. Therefore, the water inlet pipe of the existing washing machine with a washer and dryer mostly uses a tension nut clamp joint, which is more practical.

[0003] However, the stretch nut clamping joint used in the existing washer-dryer often has some shortcomings during actual use. For example, the existing stretch nut fastener is fixed at the water outlet of the faucet by a spring stretching structure. When the spring stretching structure of the stretch nut clamping joint is subjected to stress and aged for a long time, the stretching strength of the spring structure will weaken, thereby failing to effectively ensure the firmness of the connection between the faucet and the water inlet pipe. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a stretch nut fastener for a washer-dryer to solve the problem that the existing stretch nut fastener is fixed at the water outlet of the faucet by a spring stretching structure. When the spring stretching structure of the stretch nut clamp joint is subjected to stress and aged for a long time, the stretching strength of the spring structure will weaken, thereby failing to effectively ensure the firmness of the connection between the faucet and the water inlet pipe.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a stretching nut fastener for a washing machine with a washer and dryer, comprising a threaded tapping clamp and a spring stretching clamp seat, a screw fastening clamp is provided at the connection between the threaded tapping clamp and the spring stretching clamp seat, the screw fastening clamp is fixedly connected to the spring stretching clamp seat, and the spring stretching clamp seat and the screw fastening clamp can be detachably mounted on the bottom of the threaded tapping clamp.

[0006] Preferably, the threaded tapping chuck comprises a chuck body, the inner wall of the upper port of the chuck body is provided with a screw thread, the outer surface of the lower half of the chuck body is provided with a bolt positioning groove and a ball clamping groove, respectively, the bolt positioning groove is located above the ball clamping groove, rubber gaskets are bonded to the inside of the bolt positioning groove and the ball clamping groove, and the chuck body is made of nickel-chromium alloy.

[0007] Preferably, the spring stretching clamp seat includes a clamp body, the outer surface of the lower half of the clamp body is provided with a water pipe clamping groove, the interior of the water pipe clamping groove is provided with a rubber gasket, the upper half of the clamp body is provided with a ball clamp, the outside of the ball clamp is elastically sleeved with a spring stretching clamp seat through a stretch spring, an outer convex pull ring is integrally formed at the lower edge of the outer surface of the spring stretching clamp seat, the ball clamp is detachably clamped to the lower half of the clamp body through the spring stretching clamp seat and is clamped to the ball clamping groove.

[0008] Preferably, the screw fastening clamp includes an annular clamp, which is fixed to the top of the ball clamp by embedded bolts, and the side of the annular clamp is threadedly connected with four groups of equidistantly distributed flat-angle bolts, and the adjacent ends of the four groups of flat-angle bolts are integrally formed with a hemispherical clamp head, and the annular clamp is detachably clamped to the lower half of the clamp head body through the four groups of flat-angle bolts and contacts with the bolt positioning groove.

[0009] Technical effects and advantages of the utility model:
