[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0022] See attached Figure 1 The embodiment of the present application provides a sealed pipe joint, including a first joint 100 and a second joint 101. The pipes on both sides of the first joint 100 and the second joint 101 are integrally formed. The inner diameter of the first joint 100 is adapted to the outer diameter of the second joint 101, so that the first joint 100 is plugged into the inside of the second joint 101. A labyrinth-type clamping part 102 is provided on the end surfaces where the first joint 100 and the second joint 101 are plugged into each other, thereby reducing the risk of displacement of the first joint 100 and the second joint 101. Simply, the labyrinth-type clamping part 102 can be a number of shallow grooves provided along the axial direction on the inner wall surface of the first joint 100, and a number of protrusions provided on the outer wall surface of the second joint 101. The protrusions cooperate with the shallow grooves to form multiple blocking lines, which have a certain blocking effect on the displacement of the first joint 100 and the second joint 101 to both sides.

[0023] In this embodiment, a conical portion 103 is provided at one end of the second joint 101 inserted into the first joint 100, and an inner ring stage 104 is provided in the first joint 100. The conical portion 103 and the inner ring stage 104 are opposite and mutually buckled, so that the first joint 100 and the second joint 101 are relatively fixed, and the displacement of the pipes on both sides is limited. A spring 105 is sleeved on the inner ring stage 104, and the spring 105 is connected to a sealing sleeve 106. After the first joint 100 and the second joint 101 are mutually plugged, the spring 105 is compressed, so that the spring 105 exerts a thrust to fasten the sealing sleeve 106 to the conical portion 103, so that the sealing sleeve 106 seals the first joint 100 and the second joint 101 under the thrust of the spring 105.

[0024] In an exemplary embodiment, Figure 1As shown, the end face of the inner ring platform 104 is provided with a fishbone buckle 107, and the end face of the tapered portion 103 is provided with a fishbone buckle groove, and the fishbone buckle 107 is inserted into the fishbone buckle groove, so as to buckle and fix the first joint 100 and the second joint 101, which can solve the problem of lateral displacement of the pipelines on both sides.

[0025] Of course, in a preferred embodiment, in order to further lock the first connector 100 and the second connector 101, see Figure 1 As shown, a boss portion 108 is provided at the end of the first joint 100, and a boss portion 109 of the same height as the boss portion 108 is provided on the outer wall of the second joint 101. The boss portion 108 and the boss portion 109 are both provided with external threads. A locking nut 110 is sleeved on the boss portion 108. The boss portion 108 is at least twice as long as the locking nut 110. The first joint 100 and the second joint 101 are not connected, and the locking nut 110 is located on the boss portion 108. When the first joint 100 and the second joint 101 are plugged in, the locking nut 110 is rotated to connect it to the boss portion 108 and the boss portion 109, thereby completing the locking of the first joint 100 and the second joint 101.

[0026] To sum up, the sealing pipe joint provided in the embodiment of the present application fixes the first joint 100 and the second joint 101 to each other by snapping, so that the pipes on both sides remain relatively fixed and do not fall off, and at the same time, the spring 105 is used to apply a thrust to the sealing sleeve 106 so that the sealing sleeve 106 is tightly attached between the first joint 100 and the second joint 101, thereby achieving a better sealing effect and effectively solving the problem of reduced sealing of the pipe joint due to lateral displacement of the pipeline.

[0027] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
