[0003] The pipe body of the above-mentioned patent is connected to other pipes only by threads when in use. However, the sealing performance of the threaded connection alone is not good, and leakage is prone to occur when transporting liquids. Therefore, in view of the above situation, there is an urgent need to develop a stainless steel pipe that is simple in structure, easy to connect, has good sealing performance, is not prone to leakage, and is easy to install, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of the utility model is to provide a stainless steel pipe that is easy to install, so as to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A stainless steel pipe that is easy to install includes a steel pipe body, a first connecting head, a second connecting head, a sealing sleeve and a tightening ring. The first connecting head is welded and fixed to the right end of the steel pipe body, and the sealing sleeve is adhered and fixed inside the first connecting head. The inner ring diameter of the sealing sleeve gradually decreases from right to left. The second connecting head is welded and fixed to the left end of the steel pipe body. A tightening ring is provided in the second connecting head. Two connecting rods are welded and fixed to the rear side of the tightening ring. The connecting rods are welded and fixed to the inner wall of the second connecting head. The tightening ring is used to be stuck in the sealing sleeve. The outer diameter of the tightening ring is smaller than the minimum diameter of the inner ring of the sealing sleeve.

[0007] Preferably, the sealing sleeve is made of rubber.

[0008] Preferably, the tightening ring and the connecting rod are both made of stainless steel.

[0009] Preferably, the outer side of the first connector is provided with an external thread.

[0010] Preferably, the interior of the second connector is provided with an internal thread matching the external thread.

[0011] The beneficial effects of the present invention are as follows: when installing the stainless steel pipe that is easy to install, the second connector on one steel pipe body is gradually screwed onto the first connector on the other steel pipe body, and the second connector and the first connector are fixed together by matching the external thread and the internal thread. When the second connector is gradually screwed onto the first connector, the top tightening ring is gradually inserted into the sealing sleeve, and the top tightening ring gradually squeezes the inner wall of the sealing sleeve, thereby making the top tightening ring and the sealing sleeve fit more tightly, and improving the sealing performance of the connection between the first connector and the second connector through the top tightening ring and the sealing sleeve to prevent leakage. In summary, the present invention has a simple structure, convenient connection, good sealing performance, and is not easy to leak. BRIEF DESCRIPTION OF THE DRAWINGS
