[0037] Reference Figure 1-Figure 4 , Figure 4 An exploded view of a pipeline device provided in an embodiment of the present application is shown.

[0038] In some optional embodiments, the first mounting portion 11 is provided with a receiving groove 112 adapted to the second mounting portion 21, and the second mounting portion 21 extends into the receiving groove 112. That is, the thickness of the first mounting portion 11 is greater than the thickness of the second mounting portion 21, and the first mounting portion 11 is provided with a receiving groove 112 on one side facing the second mounting portion 21, and the receiving groove 112 is an annular groove, and the provision of the receiving groove 112 facilitates the second mounting portion 21 to extend therein, and when the second mounting portion 21 extends into the receiving groove 112, the tightness of the connection between the first mounting portion 11 and the second mounting portion 21 is further improved, and the protection effect of the sealing ring 3 is further improved.

[0039] In some optional embodiments, multiple connectors are provided, and the multiple connectors are arranged at intervals along the circumference of the first card plate 41 or the second card plate 42. That is, the first mounting holes 411 provided on the first card plate 41 are provided in multiple numbers and arranged at intervals along the circumference of the first card plate 41, and the second mounting holes 421 provided on the second card plate 42 are provided in multiple numbers and arranged at intervals along the circumference of the second card plate 42. The provision of multiple connectors can further improve the tightness and stability of the connection between the first card plate 41 and the second card plate 42.

[0040] In some optional embodiments, the first clamping plate 41 and the second clamping plate 42 both include a first clamping portion and a second clamping portion that are detachably connected, and the first clamping portion and the second clamping portion are surrounded by a clamping cavity, which is used to sleeve the first pipe 1 or the second pipe 2.

[0041] The first clamping plate 41 and the second clamping plate 42 have the same shape, and both the first clamping plate 41 and the second clamping plate 42 include a first clamping portion and a second clamping portion, and the first clamping portion and the second clamping portion are detachably connected, so as to facilitate the installation of the first clamping plate 41 and the first pipe 1, and the installation of the second clamping plate 42 and the second pipe 2. Among them, both ends of the first clamping portion and both ends of the second clamping portion can be detachably connected, for example, connected by a connecting piece, one end of the first clamping portion and one end of the second clamping portion can be hingedly arranged, and the other end can be detachably connected by a connecting piece, which further improves the convenience of installing the first clamping plate 41 and the first pipe 1, and the second clamping plate 42 and the second pipe 2.

[0042] In some optional embodiments, at least one connecting member is located at the first engaging portion, and at least one connecting member is located at the second engaging portion, so that the multiple connecting members are distributed more evenly, thereby improving the stability and tightness of the connection between the first clamping plate 41 and the second clamping plate 42.

[0043] In some optional embodiments, the first clamping part and the second clamping part are arranged in an arc shape, and the arc length of the first clamping part is greater than the arc length of the second clamping part. The first clamping part and the second clamping part are arranged in an arc shape, so that the first clamping part and the second clamping part are arranged to form a circular ring, and the arc length of the first clamping part is greater than the arc length of the second clamping part. During installation, the first clamping part can be clamped at the first pipe 1 or the second pipe 2, and then the second clamping part is connected to the first clamping part. Compared with the first clamping part and the second clamping part being semi-circular, the arc length of the first clamping part is greater than the arc length of the second clamping part, which is more convenient for assembly.

[0044] In some optional embodiments, the first clamping portion is used to abut against the first mounting portion 11 or the second mounting portion 21. Compared with the abutment of the second clamping portion with the first mounting portion 11 or the second mounting portion 21, the abutment of the first clamping portion with the first mounting portion 11 increases the contact area between the first clamping plate 41 and the first pipe 1, and the abutment of the first clamping portion with the second mounting portion 21 increases the contact area between the second clamping plate 42 and the second pipe 2, thereby further improving the stability of the connection between the first pipe 1 and the second pipe 2.

[0045] In some optional embodiments, the ends of the first clamping portion and the second clamping portion are both chamfered, thereby preventing the operator from being cut by the ends of the first clamping portion and / or the second clamping portion during installation, thereby improving the safety of the operator's operation.

[0046] In some optional embodiments, the sealing ring 3 is a fluororubber sealing ring or a silicone sealing ring. The material of the sealing ring 3 is fluororubber or silicone material, thereby improving the wear resistance of the sealing ring 3.
