Description

Technical Field

[0001] This utility model relates to the field of washing machine hose technology, and in particular to a rubber protective sleeve for connecting washing machine hoses. Background Technology

[0002] The washing machine hose refers to the flexible tube connecting the washing machine's water level sensor to the outer tub. The main function of the washing machine hose is to transmit water pressure to open the pressure switch, thereby starting the washing machine's program. The hose is made of inner and outer rubber layers and a reinforcing layer. The inner and outer rubber layers may be made of different types of rubber.

[0003] Existing washing machine hoses have poor stability at the joint connection point, which can easily lead to the joint separating from the hose. They also lack a sealing and protective structure, making it easy for dirt to enter the joint. This paper proposes a rubber protective sleeve for washing machine hose connections to solve the above problems. Utility Model Content

[0004] In view of the shortcomings and defects in the prior art, this utility model proposes a rubber protective sleeve for washing machine hose connection, which solves the technical problems in the prior art where the connection of the existing washing machine hose is not stable, which easily leads to the separation of the connector and the hose, and the lack of a sealing and protective structure makes it easy for dirt to enter the connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rubber protective sleeve for connecting a washing machine hose includes a hose body and a connector. The connector has a flow hole. The hose body has a threaded joint on its side wall opposite to the connector. The flow hole has a threaded interface on its annular inner wall opposite to the hose body. The threaded joint is threaded to the threaded interface. An annular sealing block is fixedly connected to the end of the threaded joint away from the hose body. The annular sealing block abuts seamlessly against the annular inner wall of the flow hole. An annular protective sleeve is fitted onto the end of the hose body outside the flow hole. The annular protective sleeve is engaged and positioned against the side wall of the connector opposite the hose body.

[0007] Preferably, the threaded connector is integrally formed with the hose body, and both the hose body and the threaded connector have the same diameter as the flow hole.

[0008] Preferably, two arc-shaped limiting pieces are fixedly connected to the inner annular walls near the left and right ends of the annular protective sleeve. The two arc-shaped limiting pieces on the same side are arranged opposite to each other, and the arc-shaped inner walls of the arc-shaped limiting pieces are pressed against the annular sidewall of the hose body.

[0009] Preferably, the annular sealing block, the annular protective sleeve, and the arc-shaped limiting piece are all corrosion-resistant rubber products.

[0010] Preferably, the annular protective sleeve has a first annular locking block and a second annular locking block on the side wall facing the connector, the first annular locking block being located inside the second annular locking block, and the connector has a first annular groove and a second annular groove on the side wall facing the hose body, the first annular locking block being inserted into the first annular groove, and the second annular locking block being inserted into the second annular groove.

[0011] Preferably, both the first annular locking block and the second annular locking block are integrally formed with the annular protective sleeve.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By connecting the threaded connector on the hose body to the threaded interface, the annular sealing block is inserted into the flow hole, and the annular protective sleeve is fitted onto the hose body, so that the arc-shaped inner wall of the arc-shaped limiting piece abuts and presses against the annular side wall of the hose body, effectively improving the stability of the joint connection and preventing the joint from separating from the hose.

[0014] 2. By connecting the annular protective sleeve to the connector, the first annular locking block and the second annular locking block are respectively inserted into the first annular locking groove and the second annular locking groove, effectively preventing dirt from entering the flow hole and ensuring normal flow in the flow hole.

[0022] Reference Figure 1-4 A rubber protective sleeve for connecting a washing machine hose includes a hose body 1 and a connector 2. The connector 2 has a flow hole 3. A threaded joint 4 is provided on the side wall of the hose body 1 facing the connector 2. A threaded interface 5 is provided on the annular inner wall of the flow hole 3 facing the hose body 1. The threaded joint 4 is threadedly connected to the threaded interface 5. The threaded joint 4 and the hose body 1 are integrally formed. The hose body 1 and the threaded joint 4 are both equal in diameter to the flow hole 3. An annular sealing block 6 is fixedly connected to the end of the threaded joint 4 away from the hose body 1. The annular sealing block 6 abuts seamlessly against the annular inner wall of the flow hole 3. An annular protective sleeve 7 is sleeved on the end of the hose body 1 outside the flow hole 3. Two arc-shaped limiting pieces are fixedly connected to the annular inner wall of the annular protective sleeve 7 near the left and right ends. Two arc-shaped limiting pieces 8 on the same side are arranged opposite each other. The arc-shaped inner walls of several arc-shaped limiting pieces 8 abut and press against the annular side wall of the hose body 1. The annular sealing block 6, the annular protective sleeve 7, and the arc-shaped limiting pieces 8 are all corrosion-resistant rubber products. The hose body 1 is connected to the connector 2. The hose body 1 is screwed to make the threaded joint 4 and the threaded interface 5 threadedly connected until the annular sealing block 6 on the threaded joint 4 is inserted into the inner side of the flow hole 3 and sealed and pressed against each other. The annular protective sleeve 7 is put on the hose body 1, so that the arc-shaped inner walls of several arc-shaped limiting pieces 8 in the annular protective sleeve 7 abut and press against the annular side wall of the hose body 1, effectively positioning the hose body 1 and the connector 2, improving the stability of the joint connection, and preventing the hose body 1 and the connector 2 from separating.

[0023] The annular protective sleeve 7 and the connector 2 are positioned and engaged with the side wall of the hose body 1. The annular protective sleeve 7 has a first annular locking block 9 and a second annular locking block 10 on the side wall of the connector 2. The first annular locking block 9 is located inside the second annular locking block 10. The connector 2 has a first annular locking groove 11 and a second annular locking groove 12 on the side wall of the hose body 1. The first annular locking block 9 is inserted into the first annular locking groove 11, and the second annular locking block 10 is inserted into the second annular locking groove 12. The first annular locking block 9 and the second annular locking block 10 are integrally formed with the annular protective sleeve 7. When the annular protective sleeve 7 is connected to the connector 2, the first annular locking block 9 and the second annular locking block 10 are respectively inserted into the first annular locking groove 11 and the second annular locking groove 12, effectively preventing dirt from entering the flow hole 3 and ensuring normal flow in the flow hole 3.

[0024] In use, the hose body 1 is connected to the connector 2. The hose body 1 is screwed to connect the threaded connector 4 and the threaded interface 5 until the annular sealing block 6 on the threaded connector 4 is inserted into the inner side of the flow hole 3 and is sealed and pressed tightly.
