When two insulated pipes need to be connected, a connecting device is usually required to achieve a sealed connection between the two.

[0003] In traditional technology, in order to achieve a sealed connection between two insulation pipes, a matching flange is generally fixed at the corresponding pipe openings of the two pipes. By tightening the bolts on the flange, the two insulation pipes can be tightly fixed together to achieve sealing. However, the addition of the flange changes the original shape and structure of the insulation pipe, which not only affects the aesthetics of the insulation pipe, but also brings inconvenience to storage and transportation; at the same time, the existence of the flange increases the complexity and difficulty of insulation pipe production, thereby increasing production costs.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4 , a heat preservation pipe connection device, comprising two pipe bodies 1, an upper fixing ring 2 and a lower fixing ring 3 are arranged at the two pipe bodies 1 at the positions opposite to the pipe openings, the upper fixing ring 2 and the lower fixing ring 3 are both fitted with the outer wall of the pipe body 1, the upper fixing ring 2 and the lower fixing ring 3 are both fixedly connected with a connecting ear 4, and the connecting ear 4 is threadedly connected with a fixing bolt 5; the design of the two fixing rings enables them to completely fit with the outer wall of the pipe body 1, thereby enhancing the stability and sealing of the two pipe bodies 1; the fixing bolt 5 ensures the tight connection between the pipe body 1 and the fixing ring to prevent any possible leakage or falling off.

[0024] An auxiliary structure for assisting the connection of the two pipe bodies 1 is provided on the upper fixing ring 2 .

[0025] The auxiliary structure includes a mounting seat 6 fixedly connected to the top of the upper fixing ring 2, the mounting seat 6 is arranged in a "mouth" shape, the top of the mounting seat 6 is threadedly connected with a rotating shaft 8, the bottom end of the rotating shaft 8 extends into the mounting seat 6 and is rotatably connected with a connecting plate 9, the outer wall of the tube body 1 is fitted with an arc plate 13, the arc plate 13 and the connecting plate 9 are fixedly connected with mounting ears 11 on the opposite side walls, the mounting ears 11 are fixedly connected with a mounting shaft 10, and the mounting shaft 10 is rotatably connected with a traction rod 12; the rotating shaft 8 can rotate freely within a certain range, thereby driving the connecting plate 9 to move accordingly; the setting of the traction rod 12 enables the connecting plate 9 to achieve relative movement after the two arc plates 13 fit the tube body 1 when moving vertically, further ensuring the stability and sealing of the connection between the pipeline openings of the two tube bodies 1.

[0026] The mounting seat 6 is provided with a first limiting member for limiting the position of the arc-shaped plate 13 , and the mounting seat 6 is provided with a second limiting member for limiting the position of the connecting plate 9 .

[0027] The first stopper includes a pair of protrusions 14 fixedly connected to the top of the arc plate 13, and a stopper rod 15 corresponding to the protrusions 14 is fixedly connected to the mounting seat 6, and the stopper rod 15 horizontally slides through the protrusions 14. The arrangement of the protrusions 14 and the stopper rod 15 allows the arc plate 13 to move horizontally stably, thereby driving the two tube bodies 1 to move relative to each other for better sealing.

[0028] The second stopper includes a vertical rod 16 fixedly connected to the mounting seat 6, and the vertical rod 16 is vertically slidably connected to the connecting plate 9, and a sliding opening 17 is provided on the connecting plate 9 to facilitate the sliding of the vertical rod 16.

[0031] The functional principle of the utility model can be explained through the following operation modes:

[0032] When using the device, first, the upper fixing ring 2 and the lower fixing ring 3 are respectively fitted at the pipe openings of the two pipe bodies 1, and then the fixing bolts 5 are screwed on the connecting ears 4 to fix the upper fixing ring 2 and the lower fixing ring 3 relative to the pipe body 1 and fit closely with the pipe body 1;

[0033] The arc plate 13 is now in contact with the outer wall of the tube body 1. The staff turns the handle 7, the handle 7 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the connecting plate 9 to move vertically downward, the connecting plate 9 drives the traction rod 12 to rotate, and the rotation of the traction rod 12 causes the two arc plates 13 to move relative to each other. The two arc plates 13 move relative to each other so that the two tube bodies 1 fit closely relative to the pipe openings, further ensuring the sealing of the two tube bodies 1.
