[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A compressor exhaust pipe comprises: a pipe body and a steel ring, wherein the steel ring is sleeved on the pipe body; the characteristics are: a positioning ring is arranged on the pipe body, a fixing through hole is arranged on the positioning ring, an annular groove is arranged on the steel ring, the annular groove corresponds to the fixing through hole, and a solder body is filled between the fixing through hole and the annular groove, so that the pipe body and the steel ring are welded and fixed.

When the exhaust pipe is connected to the compressor housing, the steel ring is located at the connection between the exhaust pipe and the compressor housing. The steel ring is a gradual annular structure from thick to thin. Compared with the existing annular sealing ring structure, the steel ring is not easy to deform or break, has a long service life, and extends the sealing path, thereby improving the sealing of the connection between the exhaust pipe and the compressor housing.

[0009] Furthermore, the connecting portion and the flaring portion are an integrally formed structure without any seams, and the structure is stable, durable, and can be quickly formed with high production efficiency.

[0010] Furthermore, a flared section is provided at one end of the tube body, thereby improving the discharge efficiency of the refrigerant.

[0011] The utility model has the following beneficial effects due to the adoption of the above technical solution:

After the solder solidifies, a solder body is formed, and the solder body fixes the positioning ring and the steel ring into one, so that the steel ring is limited and fixed on the pipe body, and the steel ring cannot be freely separated from the pipe body, and the installation is reliable; compared with the fixing method of spot welding the connection between the pipe body and the steel ring in the prior art, the utility model reduces the welding difficulty on the one hand, and improves the installation strength of the steel ring on the other hand.

[0013] The positioning ring blocks the gap between the steel ring and the tube body, and the solder body blocks the gap between the steel ring and the positioning ring, thereby preventing refrigerant leakage and having good sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1 As shown, a compressor exhaust pipe of the utility model comprises: a pipe body 1 and a steel ring 2. The pipe body 1 is a copper part. One end of the pipe body 1 is provided with a flared section 3, which improves the discharge efficiency of the refrigerant.

[0022] The inner hole diameter of the steel ring 2 matches the outer diameter of the tube body 1. The steel ring 2 includes a connection part 4 and a flared part 5. The tube body 1 passes through the connection part 4 and the flared part 5. The outer wall of the tube body 1 is in close contact with the inner wall of the steel ring 2, and the gap is very small, so as to avoid the phenomenon of refrigerant leakage at the connection. The connection part 4 and the flared part 5 are an integrated molding structure without seams, stable structure, durable, rapid molding, and high production efficiency.

[0023] When the exhaust pipe is connected to the compressor housing, the steel ring 2 is located at the connection between the exhaust pipe and the compressor housing. The steel ring 2 is a gradient annular structure from thick to thin. Compared with the existing annular sealing ring structure, the steel ring 2 is not easy to deform or break, has a long service life, and extends the sealing path, thereby improving the sealing of the connection between the exhaust pipe and the compressor housing.

[0024] like Figure 3 As shown, a positioning ring 6 is welded to the outside of the tube body 1, which is reliably fixed and ensures the installation strength of the positioning ring 6; an extension part 7 is provided on the positioning ring 6, and the extension part 7 is welded to the tube body 1, thereby increasing the contact area between the positioning ring 6 and the tube body 1, thereby improving the installation strength of the positioning ring 6 on the tube body 1.

[0025] like Figure 2 , Figure 4 As shown, a fixing through hole 8 is provided on the positioning ring 6, and an annular groove 9 is opened on the connecting portion 4. The annular groove 9 corresponds to the fixing through hole 8. A solder body 10 is filled between the fixing through hole 8 and the annular groove 9. The solder body 10 is formed by solidifying the solder produced by melting the brazing wire or brass.

[0026] During the assembly process, the steel ring 2 is put on the tube body 1 and contacts the positioning ring 6 to realize the positioning of the steel ring 2 on the tube body 1, which reduces the difficulty of positioning; then the solder is injected into the fixed through hole 8, and the solder flows into the annular groove 9 from the fixed through hole 8, and finally the solder fills the annular groove 9 and the fixed through hole 8, and the overflowed solder is wiped off. After the solder solidifies, a solder body 10 is formed, and the solder body 10 fixes the positioning ring 6 and the steel ring 2 into one, so that the steel ring 2 is limited and fixed on the tube body 1, and the steel ring 2 cannot be freely separated from the tube body 1, and the installation is reliable; compared with the fixing method of spot welding the connection between the tube body 1 and the steel ring 2 in the prior art, the utility model reduces the welding difficulty on the one hand, and improves the installation strength of the steel ring 2 on the other hand; the positioning ring 6 blocks the gap between the steel ring 2 and the tube body 1, and the solder body 10 blocks the gap between the steel ring 2 and the positioning ring 6 to prevent refrigerant leakage, and the sealing is good.

[0027] like Figure 5 As shown, the width of the annular groove 9 is greater than the aperture of the fixed through hole 8, which increases the filling amount of the solder body 10 in the annular groove 9, thereby improving the structural strength of the solder body 10 and increasing the contact area between the solder body 10 and the steel ring 2, thereby improving the connection strength between the solder body 10 and the steel ring 2.

[0028] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
