[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Embodiment 1: As Figures 1-3 shown, the present invention provides an automotive air-conditioning pipeline connection component, including a connecting block 1. Both ends of the connecting block 1 are provided with first connecting members 2. One end of the connecting block 1 is provided with a second connecting member 3, and a sealing member 4 is provided at the other end of the connecting block 1. A through groove 11 is opened inside the connecting block 1. The through groove 11 is used in cooperation with the first connecting member 2 and the second connecting member 3. The inner ends of the first connecting member 2 and the second connecting member 3 are both fixedly provided with mounting members 5. The connecting block 1 is the carrier of the connection. Different-sized automotive air-conditioning pipelines can be connected through the first connecting member 2 and the second connecting member 3. The connecting block 1 can connect four pipelines through the through groove 11, which can handle various situations and has high versatility. The unnecessary surfaces are sealed by the sealing member 4, and the sealing performance is good.

[0021] The first connecting piece 2 includes a stud 6. An outer end of the stud 6 is in movable contact with a sleeve block 61. An outer surface of the sleeve block 61 is fixedly provided with a contact ring 62. An outer surface of the sleeve block 61 is sleeved with a nut 63. An outer end of the nut 63 is fixedly provided with a limiting ring 64. An inner wall of the limiting ring 64 is provided with a fixing groove 65 for use in cooperation with the sleeve block 61. When connecting pipelines through the connecting piece, when connecting the pipelines, first remove the nut 63 and the sleeve block 61, insert the pipeline into the stud 6, and then sleeve the sleeve block 61 on the outer surface of the pipeline until the sleeve block 61 contacts the outer end of the stud 6. At this time, rotate the nut 63. During the process of screwing on the nut 63, the fixing groove 65 in the limiting ring 64 contacts the contact ring 62. As the nut 63 is continuously tightened, the contact ring 62 firmly fixes the pipeline, thereby completing the connection of the pipeline. For the connection of automotive air-conditioning pipelines, welding is not required, the operation is simple and convenient, and the connection effect is good.

[0022] The shape of the fixing groove 65 is conical, and the corresponding stud 6, contact ring 62 and nut 63 are in communication with each other, facilitating the passage of the pipeline.

[0023] The cross-sectional shape of the connecting block 1 is cross-shaped, and the shape of the through groove 11 is cross-shaped, and up to four pipelines can be connected, improving the versatility.

[0024] An inner end of the sealing member 4 is fixedly provided with a sealing ring 41, and an outer surface of the sealing ring 41 is attached to an inner wall of the through groove 11, further improving the sealing ability of the sealing member 4.

[0025] The first connecting piece 2 and the second connecting piece 3 have the same shape, and the size ratio of the first connecting piece 2 to the second connecting piece 3 is five to four, facilitating the connection and fixation of pipelines of different sizes.

[0026] Embodiment 2: As Figure 4 shown, both sides of the outer surfaces of the mounting member 5 and the sealing member 4 are fixedly provided with mounting blocks 51. An inner end of the mounting block 51 is fixedly provided with a plurality of insertion posts 52. An outer surface of the connecting block 1 is provided with a plurality of block grooves 53 for use in cooperation with the mounting blocks 51. An inner wall of the block groove 53 is provided with column grooves 54 for use in cooperation with the insertion posts 52. Both upper and lower ends of the mounting block 51 are fixedly provided with fixing blocks 55. The fixing blocks 55 and the outer surface of the connecting block 1 are bolted and connected. When installing the connecting piece and the sealing member 4, only need to insert the mounting block 51 on the mounting member 5 or the sealing member 4 into the block groove 53. At this time, the insertion posts 52 are inserted into the column grooves 54 for positioning, and then the fixing blocks 55 and the connecting block 1 are bolted and fixed, and the installation can be completed. The installation steps are simple, and the firmness and sealing performance of the installation are relatively high, making the connecting components more convenient to use.

[0027] There are three said inserting posts 52 located on the same axis, and the three inserting posts 52 are equally spaced up and down, improving the positioning effect.

[0028] Working principle: The connecting block 1 is the carrier for connection. Different-sized automotive air-conditioning pipelines can be connected through the first connecting piece 2 and the second connecting piece 3. The connecting block 1 can connect four pipelines through the through groove 11, which can handle various situations and has high versatility. The unnecessary surfaces are sealed by the sealing member 4, and the sealing performance is good.

[0029] When connecting the pipelines, first remove the nut 63 and the sleeve block 61, insert the pipeline into the stud 6, then put the sleeve block 61 on the outer surface of the pipeline until the sleeve block 61 contacts the outer end of the stud 6. At this time, rotate the nut 63. During the process of screwing on the nut 63, the fixing groove 65 in the limiting ring 64 contacts the contact ring 62. As the nut 63 is continuously tightened, the contact ring 62 firmly fixes the pipeline, thus completing the connection of the pipeline. For the connection of automotive air-conditioning pipelines, welding is not required, the operation is simple and convenient, and the connection effect is good.

[0030] The cross-shaped through groove 11 can connect up to four pipelines, improving the versatility.

[0031] The sealing ring 41 further improves the sealing ability of the sealing member 4.

[0032] When installing the connecting piece and the sealing member 4, only need to insert the installation block 51 on the installation piece 5 or the sealing member 4 into the block groove 53. At this time, the inserting post 52 is inserted into the post groove 54 for positioning, and then the fixing block 55 is bolt-fixed to the connecting block 1 through bolts, and the installation can be completed. The installation steps are simple, and the firmness and sealing performance of the installation are relatively high, making the connecting components more convenient to use.
