The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model discloses a liquid nitrogen transfer pipe that is easy to install. It includes a base plate 1, which is square in shape. A left transfer pipe 2 and a right transfer pipe 3 are located on the top of the base plate 1. The diameters of the internal circular holes in the left and right transfer pipes 2 and 3 are different. A left positioning plate 4 is sleeved on the outside of the left transfer pipe 2, and a right positioning plate 5 is sleeved on the outside of the right transfer pipe 3. The bottom surfaces of both the left and right positioning plates 4 and 5 are in contact with the top surface of the base plate 1. One end of the right transfer pipe 3 is nested inside the left transfer pipe 2. The outer surface of the rear end of the left transfer pipe 2 is nested inside the left mounting frame 6. The outer surface of the front end of the right transfer pipe 3 is nested inside the right mounting frame 7. The two sides of the front end of the right mounting frame 7 are inserted into the inner rear end of the left mounting frame 6. Threaded holes 8 are passed through the top surfaces of both sides of the left mounting frame 6. In the prior art, liquid nitrogen transport is suitable for long-distance or pipeline-difficult-to-construct applications, such as research parks. In the supply of nitrogen and the delivery of liquid nitrogen for medical applications, the current installation of different liquid nitrogen transmission tubes involves inserting two transmission tubes together and then fixing them. However, if the installation is not done well, the connection may not be tight enough, affecting the liquid nitrogen transmission effect. To address this issue, a left safety frame 6 can be fitted onto the outer rear end of the left transmission tube 2, and a right safety frame 7 can be fitted onto the outer front end of the right transmission tube 3. The left and right safety frames 6 and 7 are respectively adapted to the left and right transmission tubes 2 and 3. Taking advantage of the fact that one end of the right transmission tube 3 can be tightly fitted onto the inner side of the left transmission tube 2, the two front ends of the right safety frame 7 can be inserted into the inner rear end of the left safety frame 6. Then, bolts are screwed into the threaded holes 8 on both sides to ensure a tight connection between the left and right safety frames 6 and 7, thereby strengthening the installation connection between the left and right transmission tubes 2 and 3.

[0024] A left filter plate 9 is fixed inside the front end of the left transmission pipe 2. The overall diameter of the left filter plate 9 is the same as the internal diameter of the left transmission pipe 2. A right filter plate 10 is fixed inside the rear end of the right transmission pipe 3. The overall diameter of the right filter plate 10 is the same as the internal diameter of the right transmission pipe 3. Multiple filter holes 11 are penetrating the outer surfaces of both the left filter plate 9 and the right filter plate 10. For liquid nitrogen transmission with high purity requirements, setting the left filter plate 9 and the right filter plate 10 helps to maintain stable production quality and process flow. Support plates 12 are fixed at both ends of the left positioning plate 4 and the right positioning plate 5. Multiple support plates 12 are threadedly connected to the placement base plate 1 with reinforcing bolts 13, which can achieve the effect of fixing the left positioning plate 4 and the right positioning plate 5, and facilitate the stable placement of the left transmission pipe 2 and the right transmission pipe 3. Heat insulation sleeves 14 are fixed on the outer surfaces of the front end of the left transmission pipe 2 and the rear end of the right transmission pipe 3. The overall length of the heat insulation sleeves 14 at both ends is different, which achieves the effect of protecting the front end of the left transmission pipe 2 and the rear end of the right transmission pipe 3.

[0025] A reinforcing rib 15 is snapped between the left positioning plate 4 and the right positioning plate 5. The reinforcing rib 15 is square in shape, which can strengthen the connection between the left positioning plate 4 and the right positioning plate 5. The right mounting frame 7 and the left mounting frame 6 both adopt an inverted T-shaped structure. Through the stability of the right mounting frame 7 and the left mounting frame 6, base blocks 16 are fixed around the bottom of the base plate 1. The multiple base blocks 16 adopt a frustum-shaped design, which can facilitate the stability of the overall device. The interior of the left mounting frame 6 and the right mounting frame 7 are smooth to avoid wear on the left transmission pipe 2 and the right transmission pipe 3.

[0026] Working principle: First, the support plate 12 and the reinforcing bolts 13 are used to securely place the left transmission pipe 2 and the right transmission pipe 3. Then, the left filter plate 9 is fixed inside the front end of the left transmission pipe 2, and the right filter plate 10 is fixed inside the rear end of the right transmission pipe 3. This helps to maintain stable production quality and process flow. Then, taking advantage of the fact that one end of the right transmission pipe 3 can be tightly fitted into the inside of the left transmission pipe 2, the two ends of the front side of the right mounting frame 7 can be inserted into the inner side of the rear end of the left mounting frame 6. Then, bolts are screwed into the threaded holes 8 on both sides to make the left mounting frame 6 and the right mounting frame 7 tightly connected, thereby strengthening the installation connection effect of the left transmission pipe 2 and the right transmission pipe 3.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments.
