UTILITY MODEL CONTENTS

[0004] The utility model aims at solving the problem that the end radius of threaded connection column is substantially consistent with the radius of the position connected on the other side when being connected, threaded connection column is not easy to enter the connecting position on the other side, and it needs a long time to connect the heat preservation pipes on two sides together, and provides a kind of reinforced heat preservation steel pipe.

[0005] To achieve the above object, the utility model provides the following technical scheme:

[0006] Design a kind of reinforced heat preservation steel pipe, including first heat preservation pipe and second heat preservation pipe, the right side of the first heat preservation pipe is equipped with second heat preservation pipe, the first heat preservation pipe and second heat preservation pipe both sides are fixedly connected with first joint and second joint, the outer side of the first joint is equipped with mounting structure, the outer wall of the first heat preservation pipe and second heat preservation pipe is fixedly connected with protective sleeve.

[0007] Preferably, the mounting structure includes a tapered cylinder, the outer wall of the tapered cylinder is fixedly connected with a rubber pad on the right side, the outer wall of the rubber pad is tightly abutted with a tapered groove, the outer wall of the tapered cylinder is machined with external threads on the left side, the external threads are threadedly connected with internal threads, and the end of the tapered cylinder is fixedly connected with the first joint.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] See attached document Figures 1-5In this embodiment, a reinforced thermal insulation steel pipe includes a first thermal insulation pipe 1 and a second thermal insulation pipe 4. The first thermal insulation pipe 1 is provided with the second thermal insulation pipe 4 on the right side. The first thermal insulation pipe 1 and the second thermal insulation pipe 4 are fixedly connected with a first connector 3 and a second connector 5 on both sides. The first connector 3 is provided with a mounting structure 6 on the outer side. The first thermal insulation pipe 1 and the second thermal insulation pipe 4 are fixedly connected with a protective sleeve 2 on the outer wall. The material of the first thermal insulation pipe 1 and the second thermal insulation pipe 4 is glass fiber reinforced plastic, which has high tensile strength and rigidity. The material of the protective sleeve 2 is polyethylene, which has corrosion resistance and pressure resistance.

[0020] The mounting structure 6 includes a tapered cylinder 601. The tapered cylinder 601 is fixedly connected with a rubber pad 602 on the outer wall on the right side. The outer wall of the rubber pad 602 is tightly abutted with a tapered groove 603. The outer wall of the tapered cylinder 601 is processed with external threads 604 on the left side. The external threads 604 are threadedly connected with internal threads 605. The tapered cylinder 601 is fixedly connected with the first connector 3. The tapered groove 603 is processed in the inner wall on the right side of the second connector 5. The internal threads 605 are processed in the inner wall of the second connector 5. The internal threads 605 are located on the left side of the tapered groove 603.

[0021] Working principle:

[0022] When using the reinforced protective steel pipe:

[0023] The operator inserts the tapered cylinder 601 on the first connector 3 on the left side of the second thermal insulation pipe 4 into the tapered groove 603 on the second connector 5 on the right side of the first thermal insulation pipe 1. The inner wall of the tapered groove 603 is beveled, which makes the tapered cylinder 601 easily enter the second connector 5 on the right side of the first thermal insulation pipe 1. Then, the second thermal insulation pipe 4 is rotated, so that the tapered cylinder 601 is screwed into the second connector 5 on the right side of the first thermal insulation pipe 1. When the rubber pad 602 is tightly abutted with the inner wall of the tapered groove 603, the rubber pad 602 can play a sealing role. The rotation of the second thermal insulation pipe 4 is stopped, so that the first thermal insulation pipe 1 and the second thermal insulation pipe 4 can be connected together. This can make the tapered cylinder 601 more easily aligned with the second connector 5, and the first thermal insulation pipe 1 and the second thermal insulation pipe 4 can be connected together in a shorter time.

[0024] The first thermal insulation pipe 1 and the second thermal insulation pipe 4 are of the same type. They are divided into two structures only to distinguish the connection relationship. When in use, multiple thermal insulation pipes are connected together in the above manner. The first thermal insulation pipe 1 and the second thermal insulation pipe 4 are fixedly connected with the first connector 3 and the second connector 5 on both sides, which facilitates the connection of the first thermal insulation pipe 1 and the second thermal insulation pipe 4. The first thermal insulation pipe 1 and the second thermal insulation pipe 4 are fixedly connected with the protective sleeve 2 on the outer wall. The material of the protective sleeve 2 is polyethylene, which has corrosion resistance and pressure resistance. At the same time, high-density polyethylene can play a thermal insulation role on the first thermal insulation pipe 1 and the second thermal insulation pipe 4, thereby increasing the pressure resistance of the first thermal insulation pipe 1 and the second thermal insulation pipe 4. The material of the first thermal insulation pipe 1 and the second thermal insulation pipe 4 is glass fiber reinforced plastic, which has high tensile strength and rigidity.
