Detailed implementation manners

[0013] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0014] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0015] Refer to Figures 1 to 3 It can be seen that a pipeline connection structure includes Pipeline 1, Pipeline 2, Sleeve 3 and Snap - fastener 4. Pipeline 1 and Pipeline 2 are inserted and installed in Sleeve 3. The outer ends of Pipeline 1 and Pipeline 2 are respectively integrally provided with Baffle 1 and Baffle 2. Inside Baffle 1 and Baffle 2, Pipeline 1 and Pipeline 2 are respectively fixedly connected with Positioning platform 1 and Positioning platform 2. One ends of Pipeline 1 and Pipeline 2 located inside Sleeve 3 are respectively installed with Sealing ring 5 through a sealing groove. Card slot 1 and Card slot 2 are respectively opened on Pipeline 1 and Pipeline 2 located inside Sleeve 3. Snap - in mounting grooves 301 corresponding to Card slot 1 and Card slot 2 are respectively opened on Sleeve 3, and Snap - fasteners 4 are respectively installed in the two Snap - in mounting grooves 301. Positioning grooves 302 corresponding to Positioning platform 1 and Positioning platform 2 are respectively opened at both ends of Sleeve 3. Positioning platform 1 and Positioning platform 2 cooperate with Positioning grooves 302 to position Sleeve 3.

[0016] After the two buckles 4 are installed, they respectively pass through the outer wall of the sleeve 3 and are snapped into the first slot 103 and the second slot 203. This design can lock the states of the first pipeline 1 and the second pipeline 2 after being installed into the sleeve 3. The buckle 4 is made of an elastic material, which is convenient for the installation and disassembly of the buckle 4. The sealing ring 5 is made of rubber material, which has good sealing effect and good elasticity, making it convenient for the installation of components.

[0017] Principle and advantages of the present utility model: For a pipeline connection structure, during installation, first slip the sleeve 3 onto the first pipeline 1, then butt the first pipeline 1 and the second pipeline 2, and then move the sleeve 3 on the first pipeline 1 until the sleeve 3 is sleeved with the second pipeline 2 and the second positioning platform 201 is docked with the positioning groove 302. One end of the sleeve 3 abuts against the second retaining edge 202. At this time, the first slot 103 and the second slot 203 respectively correspond to the buckle installation slots 301 on the sleeve 3. Then snap the two buckles 4 into the buckle installation slots 301 respectively. A part of the buckle 4 will be snapped into the first slot 103 and the second slot 203, which can lock the states of the first pipeline 1 and the second pipeline 2 after connection. The sealing ring 5 contacts the inner wall of the sleeve 3 to play a sealing role, ensuring the sealing performance. The structure of the present utility model is simple and reasonable, the connection is fast and convenient, the sealing performance is good, the manufacturing cost is low, and it is suitable for popularization and use.
