[0006] According to the sealing protection device for a water pipe bend, the insulating sleeve is made of rubber or silicone material, and both ends of the inner side of the insulating sleeve are fixedly contacted and connected with the sealing ring.

[0007] According to the sealing protection device for a water pipe bend, two sealing rings are provided, and both of the two sealing rings are in the form of ring-shaped elastic rings.

[0008] According to the sealing protection device for the bend of a water pipe, two pull rings are provided, both of which are made of polytetrafluoroethylene, and both of which are fixedly contacted and connected with the surfaces at both ends of the outer side of the isolation sleeve.

[0009] According to the sealing protection device for water pipe bends, four fixing rings are provided, and the four fixing rings are all metal semi-ring shaped structures, thereby forming two groups of overall circular structures. The two groups of fixing rings are respectively in contact with and connected to the outer end surfaces of the isolation sleeve above the sealing ring.

[0010] According to the sealing protection device at the bend of a water pipe, four fixing bolts are provided, and the four fixing bolts are all threadedly fixedly connected with the inside of one side of the fixing ring. The two sides of the fixing ring are tightly fixedly contacted with the outer end surfaces of the isolation sleeve above the sealing ring through the fixing bolts.

[0011] The above scheme has the beneficial effects: by setting up the isolation sleeve and the pull ring, the isolation sleeve made of rubber, silicone or other flexible materials can adapt to the bending of the pipeline, avoid gaps between the angle bends, protect the water pipe from damage at the bent part, and prevent leakage. When using the pull ring, a pulling force can be provided when one end of the isolation sleeve is moved toward the side of the water pipe, preventing the isolation sleeve from being difficult to bend when installed at the bend of the water pipe, thereby providing good sealing protection for the bend of the water pipe.

[0012] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-4The utility model discloses a sealing protection device for a bend in a water pipe, which includes an isolating sleeve 1. Sealing rings 2 are arranged at both ends of the inner side of the isolating sleeve 1. Pull rings 3 and fixing rings 4 are arranged on the surfaces of both ends of the outer side of the isolating sleeve 1. Fixing bolts 5 are arranged inside the fixing ring 4 on both sides.

[0021] The isolation sleeve 1 is made of rubber or silicone material, and both ends of the inner side of the isolation sleeve 1 are fixedly contacted and connected with the sealing ring 2. The isolation sleeve 1 is usually made of rubber, silicone or other flexible materials to adapt to the bending of the water pipe, protect the water pipe from damage in the bending part, and prevent leakage. Two sealing rings 2 are provided, and both sealing rings 2 are ring-shaped elastic ring styles. The sealing ring 2 is provided to ensure the sealing state between the isolation sleeve 1 and the outside of the water pipe to prevent leakage at the bend of the water pipe. Two pull rings 3 are provided, and both pull rings 3 are made of polytetrafluoroethylene. Both pull rings 3 are fixedly contacted and connected with the surfaces of the two ends of the outer side of the isolation sleeve 1. Through the set pull ring 3, the inside of one end of the isolation sleeve 1 can be moved toward the side of the water pipe. Provide pulling force to prevent the isolation sleeve 1 from being difficult to bend when being installed at the bend of the water pipe. Four fixing rings 4 are provided. The four fixing rings 4 are all metal semi-ring shaped structures, thereby forming two groups of overall circular structures. The two groups of fixing rings 4 are respectively in contact and connected with the outer end surfaces of the isolation sleeve 1 above the sealing ring 2. The isolation sleeve 1 can be fixed above the water pipe by the set fixing rings 4. Four fixing bolts 5 are provided. The four fixing bolts 5 are all threadedly fixedly connected with the inside of one side of the fixing ring 4. The two sides of the fixing ring 4 are tightly fixedly contacted and connected with the outer end surfaces of the isolation sleeve 1 above the sealing ring 2 through the fixing bolts 5. The fixing bolts 5 can keep the fixing ring 4 stable above the isolation sleeve 1.

[0022] Working principle: Put the isolation sleeve 1 from one end of the water pipe onto the outer surface of the water pipe, and use the pull ring 3 to provide pulling force when the inner end of the isolation sleeve 1 moves toward the side of the water pipe, saving effort to pull the isolation sleeve 1 and fully seal the bend of the water pipe to protect the water pipe from damage, and then use the sealing rings 2 at both ends of the inner side of the isolation sleeve 1 to provide a sealing effect within the bend of the water pipe to prevent leakage of the water pipe. The fixing ring 4 and the fixing bolt 5 ensure that the sealing ring 2 is firmly installed on the water pipe to maintain its stability.
