Description

Technical Field

[0001] This utility model relates to the field of shaped tube technology, and in particular to a stainless steel shaped tube. Background Technology

[0002] Shaped seamless steel pipes are a general term for seamless steel pipes with cross-sectional shapes other than round pipes. Type D stainless steel pipe is a common type of shaped pipe, frequently used in construction, automotive, and agricultural fields. However, existing Type D stainless steel pipes often require bolts for connection, which is cumbersome to install and results in poor sealing, leading to leaks at the joints. Therefore, there is an urgent need to develop a type of stainless steel shaped pipe that is easy to connect, provides double sealing at the joints, and offers better overall sealing performance to overcome the shortcomings in current applications and meet current needs. Utility Model Content

[0003] The purpose of this utility model is to provide a stainless steel special-shaped tube to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A stainless steel shaped tube includes a shaped tube, a plug frame, a first sealing ring, a snap ring, and a second sealing ring. The plug frame is welded and fixed to the left end of the shaped tube. The first sealing ring is fixedly installed on the outer side of the plug frame. The outer dimension of the first sealing ring is one millimeter larger than the inner dimension of the shaped tube. The snap ring is fixedly installed on the inner right end of the shaped tube. The second sealing ring is fixed on the snap ring. The outer dimension of the second sealing ring is one millimeter larger than the inner dimension of the plug frame.

[0006] Preferably, the left end of the first sealing ring of this invention is provided with a first chamfer.

[0007] Preferably, the end of the second sealing ring of this invention is provided with a second chamfer.

[0008] Preferably, the shaped tube of this utility model includes a base plate and a top cover, wherein the base plate and the top cover are welded and fixed together, and the base plate and the top cover form a "D" shape.

[0009] Preferably, the inner top of the shaped tube of this invention is welded and fixed with multiple reinforcing ribs.

[0010] Preferably, the base plate, top cover, plug-in frame, reinforcing ribs and snap-fit ​​rings of this utility model are all made of stainless steel.

[0011] The beneficial effects of this utility model are as follows: When connecting the stainless steel shaped tubes, the insertion frame on the left side of one shaped tube is inserted into the right end of another shaped tube. The insertion frame and the first sealing ring are gradually inserted into the shaped tube, and the first sealing ring is gradually compressed, making it tightly adhere to the inner wall of the shaped tube, achieving the first seal. Subsequently, as the insertion frame and the first sealing ring continue to be inserted, the second sealing ring gradually enters the inner ring of the insertion frame, and the second sealing ring is gradually compressed, making it tightly adhere to the inner wall of the insertion frame, achieving the second seal. In summary, this utility model facilitates interconnection and provides a double seal during interconnection, resulting in better sealing performance. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] See Figures 1-7 In this embodiment of the utility model, a stainless steel shaped tube includes a shaped tube 1, a plug frame 2, a first sealing ring 3, a snap ring 5, and a second sealing ring 6. The plug frame 2 is welded and fixed to the left end of the shaped tube 1. The first sealing ring 3 is fixedly installed on the outer side of the plug frame 2. The outer dimension of the first sealing ring 3 is one millimeter larger than the inner dimension of the shaped tube 1, so that the first sealing ring 3 is squeezed tightly when inserted into the shaped tube 1. The left end of the first sealing ring 3 is provided with a first chamfer 301. The angle 301 facilitates the insertion of the first sealing ring 3 into the shaped tube 1. The snap ring 5 is fixedly installed on the inside right end of the shaped tube 1. The snap ring 5 is fixed with a second sealing ring 6. The outer dimension of the second sealing ring 6 is one millimeter larger than the inner dimension of the insertion frame 2, so that the second sealing ring 6 will be squeezed tightly after being inserted into the insertion frame 2, resulting in a higher sealing performance. The end of the second sealing ring 6 is provided with a second chamfer 601, which facilitates the insertion of the second sealing ring 6 into the insertion frame 2.

[0024] The shaped tube 1 includes a base plate 101 and a top cover 102. The base plate 101 and the top cover 102 are welded and fixed together, and the base plate 101 and the top cover 102 form a "D" shape.

[0025] Multiple reinforcing ribs 4 are welded and fixed to the inner top of the shaped tube 1, thereby increasing the strength of the shaped tube 1.

[0026] The base plate 101, top cover 102, plug frame 2, reinforcing rib 4 and snap ring 5 are all made of stainless steel, giving them good strength and corrosion resistance.

[0027] Working principle: When these stainless steel shaped tubes are connected, the insertion frame 2 on the left side of one shaped tube 1 is inserted into the right end of another shaped tube 1. The insertion frame 2 and the first sealing ring 3 are gradually inserted into the shaped tube 1. The first sealing ring 3 is gradually compressed, making it tightly fit against the inner wall of the shaped tube 1, achieving the first seal. As the insertion frame 2 and the first sealing ring 3 continue to be inserted, the second sealing ring 6 gradually enters the inner ring of the insertion frame 2, and the second sealing ring 6 is gradually compressed, making it tightly fit against the inner wall of the insertion frame 2, achieving the second seal.

[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
