However, when the liquid is transported at high pressure, the pipe fittings may loosen or even fall off, thus affecting their performance and failing to effectively tighten and prevent them from falling off. Utility Model Content

[0004] The purpose of this utility model is to provide a galvanized pipe connection device to prevent detachment, which solves the problem that when the liquid is transported at a high pressure, the connection of the pipe fittings may become loose or even detach, thus affecting the performance and failing to effectively tighten and prevent detachment.

[0005] To achieve the above objectives, a galvanized pipe connection device for preventing detachment is provided, comprising: a first galvanized pipe and a second galvanized pipe, one end of the first galvanized pipe being fixedly connected to an externally threaded pipe, the external thread of the externally threaded pipe being connected to the second galvanized pipe, several triangular welded parts being welded to the outer surfaces of both the first and second galvanized pipes, two sets of first arc-shaped clamps and second arc-shaped clamps being respectively fitted onto the middle and one end of the outer surfaces of the first and second galvanized pipes, both ends of the first and second arc-shaped clamps being fixedly connected to lugs, bolts penetrating the interior of the lugs, the inner sidewalls of the first and second arc-shaped clamps being in contact with the triangular welded parts, and a connecting rod being fixedly connected between the two sets of first and second arc-shaped clamps.

[0006] According to the aforementioned galvanized pipe connection device for preventing detachment, U-shaped seats are fixedly connected to both sides of the second arc-shaped clamp, and a rotating shaft is rotatably connected inside a set of the U-shaped seats.

[0007] According to the aforementioned galvanized pipe connection device for preventing detachment, a rotating block is fixedly connected between the rotating shafts.

[0008] According to the aforementioned galvanized pipe connection device for preventing detachment, a rotating rod is fixedly connected to one side of the rotating block, and one end of the rotating rod is provided with an external thread.

[0009] According to the aforementioned galvanized pipe connection device for preventing detachment, a nut is threaded into the middle of the external thread.

[0010] According to the aforementioned galvanized pipe connection device for preventing detachment, one side of the triangular weldment is at a 90-degree angle, and the other side is at an inclined angle.

[0011] According to the aforementioned galvanized pipe connection device for preventing detachment, the number of a set of triangular welded parts is one, and they are equidistantly distributed on the circumferential surface of the first galvanized pipe or the second galvanized pipe.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] 1. This utility model incorporates a triangular weldment, a first arc-shaped clamp, and a second arc-shaped clamp. During production, several triangular weldments are equidistantly welded to the end connection positions of the first and second galvanized pipes, facilitating the use and installation of the galvanized pipes. Subsequently, when the first and second galvanized pipes are connected, the externally threaded pipe is threadedly fastened to the inner wall of the second galvanized pipe. After fixing, two sets of first and second arc-shaped clamps are fitted onto the surfaces of the first and second galvanized pipes, and one side is fitted against the right-angled surface of the triangular weldment. This structure effectively limits the contact between the first and second arc-shaped clamps, increasing their stability.

[0024] Reference Figure 1-4 This utility model discloses a galvanized pipe connection device to prevent detachment, comprising: a first galvanized pipe 1 and a second galvanized pipe 2. One end of the first galvanized pipe 1 is fixedly connected to an externally threaded pipe 7. When the first galvanized pipe 1 and the second galvanized pipe 2 are connected, the externally threaded pipe 7 is threadedly fastened to the inner wall of the second galvanized pipe 2. The external thread of the externally threaded pipe 7 is connected to the second galvanized pipe 2. Several triangular welded parts 11 are welded to the outer surfaces of both the first galvanized pipe 1 and the second galvanized pipe 2. Several triangular welded parts 11 are welded at corresponding equidistant intervals at the end connection positions of the first galvanized pipe 1 and the second galvanized pipe 2 to facilitate the use and installation of the galvanized pipe. Two sets of first arc-shaped clamps 3 and second arc-shaped clamps 5 are respectively fitted on the middle and one end of the outer surfaces of the first galvanized pipe 1 and the second galvanized pipe 2. The surfaces of the first galvanized pipe 1 and the second galvanized pipe 2 are fitted together by one side with the right angle of the triangular weld 11. Then, the first arc-shaped clamp 3 is fastened by bolts. Both ends of the first arc-shaped clamp 3 and the second arc-shaped clamp 5 are fixedly connected with lugs, and bolts pass through the lugs. The inner sidewalls of the first arc-shaped clamp 3 and the second arc-shaped clamp 5 are in contact with the triangular weld 11. A connecting rod 6 is fixedly connected between the two sets of first arc-shaped clamp 3 and second arc-shaped clamp 5. The first arc-shaped clamp 3 is firmly fitted on the surface of the galvanized pipe, and the connection between the first arc-shaped clamp 3 and the second arc-shaped clamp 5 is increased by the connecting rod 6 to achieve firmness. One side of the triangular weld 11 is 90 degrees and the other side is inclined. There are 8 triangular welds 11 in a set, and they are evenly distributed on the circumferential surface of the first galvanized pipe 1 or the second galvanized pipe 2.

[0025] Both sides of the second arc-shaped clamp 5 are fixedly connected to U-shaped seats 10. A rotating shaft is rotatably connected inside a set of U-shaped seats 10. A rotating block 9 is fixedly connected between the rotating shafts. A rotating rod 4 is fixedly connected to one side of the rotating block 9.

One end of the rotating rod 4 is provided with an external thread. A nut 8 is threadedly connected to the middle of the external thread. The nut 8 and the rotating rod 4 rotate threadedly, which squeezes the threads of the second arc-shaped clamp 5 on both sides to close the first galvanized pipe 1 and the second galvanized pipe 2, so as to achieve a tight fit and prevent it from coming off easily.

[0026] Working principle: During production, several triangular welded parts 11 are welded at corresponding equidistant intervals at the end connection positions of the first galvanized pipe 1 and the second galvanized pipe 2 to facilitate the use and installation of the galvanized pipes. Subsequently, when the first galvanized pipe 1 and the second galvanized pipe 2 are connected, the externally threaded pipe 7 is threaded and tightened to the inner wall of the second galvanized pipe 2. After fixing, two sets of first arc-shaped clamps 3 and second arc-shaped clamps 5 are both fitted onto the surfaces of the first galvanized pipe 1 and the second galvanized pipe 2, and are fitted with the right-angled surface of the triangular welded parts 11 on one side. Then, the first arc-shaped clamps are tightened with bolts. After the clamp 3 is tightened, the first arc-shaped clamp 3 is firmly fitted onto the surface of the galvanized pipe, and the connection between the first arc-shaped clamp 3 and the second arc-shaped clamp 5 is increased by the connecting rod 6 to ensure firmness. Then, one end of the rotating rod 4 is flipped so that the rotating rod 4 is inserted into the inner wall of the U-shaped seat 10 on both sides of the second arc-shaped clamp 5 at one end of the second galvanized pipe 2. Then, the nut 8 is used to rotate the rotating rod 4 threadedly, which squeezes the threads of the second arc-shaped clamp 5 on both sides to close the first galvanized pipe 1 and the second galvanized pipe 2, achieving a tight fit that is not easy to come off.
