[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a weld-free automotive air conditioning copper pipe sealing joint, comprising a first copper pipe 1, one end surface of the first copper pipe 1 in contact with one end surface of the second copper pipe 2, and a first connector 3 fixedly connected to the outer surface of the end of the first copper pipe 1 in contact with the second copper pipe 2, and a second connector 4 fixedly connected to the outer surface of the end of the second copper pipe 2 in contact with the first copper pipe 1, a plug ring 5 connected to the left side surface of the second connector 4, one end of the plug ring 5 slidingly inserting into a slot 6 opened on the right side surface of the first connector 3, connecting blocks 9 connected to both ends of the second connector 4, one end of the connecting block 9 extending into a connecting groove 10, the connecting groove 10 being opened on the right side surface of a protrusion 11, the protrusion 11 being connected to both ends of the first connector 3, and a bolt 12 penetratingly connected to the top surface of the protrusion 11, one end of the bolt 12 extending into a fixing hole 13 opened on the outer side surface of the connecting block 9.

[0023] Preferably, two sets of first sealing rings 7 are connected to the outer surface of one end of the insertion ring 5. One end of the first sealing ring 7 extends into the first slot 8 opened on the inner surface of the slot 6. The first sealing ring 7 forms an engaging structure with the first connector 3 through the first slot 8.

[0024] In practical use, when the insert ring 5 slides into the insert ring 5, the insert ring 5 will move the first sealing ring 7 connected on the outside to the first slot 8, so that the first sealing ring 7 is elastically engaged in the first slot 8, thereby increasing the sealing between the insert ring 5 and the first connector 3. In this way, the medium flowing inside the first copper tube 1 and the second copper tube 2 will not escape from the slot 6, ensuring the sealing when the first copper tube 1 and the second copper tube 2 are connected through the first connector 3 and the second connector 4.

[0025] Preferably, the position and size of the connecting block 9 match the position and size of the connecting groove 10, the connecting block 9 forms a sliding connection with the protrusion 11 through the connecting groove 10, and the bolt 12 forms a threaded connection with the fixing hole 13 through the protrusion 11.

[0026] In practical use, the connecting block 9 can be slidably inserted into the connecting groove 10. When the connecting block 9 is slidably inserted into the connecting groove 10, the bolt 12 is screwed through the protrusion 11 into the fixing hole 13, so that the position of the connecting block 9 is fixed in the connecting groove 10, and the second connector 4 is connected to the first connector 3.

[0027] Preferably, a threaded groove 14 is provided on the top surface of the protrusion 11 on the outer side of the bolt 12, and a surface thread 15 is threaded inside the threaded groove 14. The surface thread 15 is provided on the outer surface of the bottom end of the cover 16.

[0028] In practical use, the cover 16 is screwed on so that it can be screwed into the threaded groove 14 on the protrusion 11 through the surface thread 15, so that the position of the cover 16 can be fixed on the protrusion 11 and the head of the bolt 12 can be covered. The cover 16 is screwed on again so that it can be separated from the protrusion 11, and the head of the bolt 12 can be exposed again.

[0029] Preferably, a second sealing ring 17 is connected to the outer surface of the cover 16 at the upper end of the surface thread 15, and one end of the second sealing ring 17 extends into the second slot 18 opened on the inner surface at the top of the thread groove 14.

[0030] In practical use, when the cover 16 is screwed into the threaded groove 14 through the surface thread 15, the cover 16 will move with the second sealing ring 17 to the second slot 18, so that the second sealing ring 17 can be elastically engaged in the second slot 18, thereby improving the sealing between the cover 16 and the protrusion 11.

[0031] Working principle: When using this weld-free automotive air conditioning copper pipe sealing connector, when the first copper pipe 1 and the second copper pipe 2 of the automotive air conditioning system need to be connected, the insert ring 5 on one side of the second connector 4 on the second copper pipe 2 is slidably inserted into the slot 6 on the first connector 3. At this time, the connecting block 9 on the outside of the second connector 4 will also slide into the connecting groove 10 opened at one end of the protrusion 11 on the first connector 3. When the insert ring 5 is fully inserted into the slot 6, the insert ring 5 will move the first sealing ring 7 connected on the outside to the first slot 8, so that the first sealing ring 7 is elastically engaged in the first slot 8, thereby increasing the sealing between the insert ring 5 and the first connector 3. In this way, the medium flowing inside the first copper pipe 1 and the second copper pipe 2 will not escape from the slot 6. Then, the bolt 12 is screwed through the protrusion 11 and into the fixing hole 13, so that the position of the connecting block 9 is fixed in the connecting groove 10, and the first connector 3 and the second connector 4 are fixedly connected together. At this point, the first copper pipe 1 can come into contact with the second copper pipe 2, thus completing the connection between the first copper pipe 1 and the second copper pipe 2. This prevents operators from having to connect the first copper pipe 1 and the second copper pipe 2 by welding, avoiding the possibility of incomplete welding. Secondly, after the bolt 12 is installed, the cover 16 is screwed into the threaded groove 14 on the protrusion 11 through the surface thread 15. At this time, the cover 16 will move with the second sealing ring 17 to the second slot 18, allowing the second sealing ring 17 to be elastically engaged in the second slot 18, improving the sealing between the cover 16 and the protrusion 11. In this way, the cover 16 can cover the head of the bolt 12, reducing the contact between the bolt head and the external environment, preventing the bolt head from being directly exposed to the environment and easily corroded and aged, thereby improving the service life of the bolt head and making the next operation of the bolt head more convenient.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
