[0028] A docking component 2 is arranged between the two pipeline bodies 1. The docking component 2 includes a first docking sleeve 201 and a second docking sleeve 202 fixedly connected to the end parts of different pipeline bodies 1 respectively;

[0029] Among them, a dust-proof component 3 is arranged inside the second docking sleeve 202. The first docking sleeve 201 is inserted into the second docking sleeve 202. The first docking sleeve 201 is fitted with a sealing ring 203, and the sealing ring 203 is fixedly connected to the second docking sleeve 202; the sealing ring 203 is tightly pressed by the first docking sleeve 201 and the second docking sleeve 202, so that there is good airtightness at the pipeline connection.

[0030] Among them, a control sleeve 204 is fixedly connected to the end of the second docking sleeve 202. A plurality of ball grooves 205 are arranged on the outer side of the control sleeve 204. A locking ball 207 is movably installed in the ball groove 205. The locking ball 207 is snap-connected to a locking groove 206. The locking groove 206 is arranged outside the first docking sleeve 201. The locking ball 207 can be disengaged from the ball groove 205, but cannot be completely disengaged. Under the extrusion of the trapezoidal block 211, the locking ball 207 will be reinserted into the ball groove 205.

[0031] The first docking sleeve 201 is inserted into the control sleeve 204. A stepped groove 209 is arranged on the outer side of the end of the second docking sleeve 202 close to the first docking sleeve 201. A return spring 210 is arranged inside the stepped groove 209. A moving sleeve 208 is slidably installed outside the second docking sleeve 202. A plurality of trapezoidal blocks 211 are fixedly installed on the inner side of the moving sleeve 208. The trapezoidal blocks 211 are in contact with the locking balls 207. The return spring 210 is fixedly connected to the trapezoidal blocks 211. The end of the moving sleeve 208 is in contact with a limiting ring 212. The limiting ring 212 is fixedly installed outside the first docking sleeve 201; the return spring 210 can push the moving sleeve 208 to move towards the limiting ring 212, and the limiting ring 212 can block the moving sleeve 208 from continuing to move. The return spring 210 is sleeved outside the second docking sleeve 202.

[0032] On the side of the outer part of the second docking sleeve 202 away from the first docking sleeve 201, a bent plate 214 is fixedly installed. The moving sleeve 208 is located between the first docking sleeve 201 and the bent plate 214. Two clamping grooves 213 are formed on the outer side of the moving sleeve 208. The distance between the two clamping grooves 213 is the maximum distance that the moving sleeve 208 can move. A bent plate 214 is fixedly installed on the outer side of the second docking sleeve 202. A movable rod 215 is slidably installed through the outer side of the bent plate 214. One end of the movable rod 215 is fixedly connected with a clamping head 217. A first spring 216 is sleeved on the outer part of the other end of the movable rod 215. The clamping head 217 is engaged with the clamping groove 213. The clamping head 217 and the clamping groove 213 can keep the moving state of the moving sleeve 208 fixed. One end of the first spring 216 is fixedly connected with one end of the movable rod 215, and the other end of the first spring 216 is fixedly connected with the outer side of the bent plate 214.

[0033] The dust separation component 3 includes bent rods 301 symmetrically fixed to the inner side of the second docking sleeve 202. The bent rods 301 are inserted with dust screens 302. An extension plate 303 is fixedly connected to the outer surface of the dust screen 302. The dust screen 302 filters the dust in the air of the air-conditioning duct.

[0034] One side of the extension plate 303 close to the bent rod 301 is fixedly connected with a second spring 304. The bottom end of the second spring 304 is fixedly connected with an insertion post 305. A lever 306 is fixedly connected to the outer side of the insertion post 305. The insertion post 305 is inserted into the bent rod 301.

[0035] Working principle: Before using this quick connection structure for automotive air-conditioning pipelines, it is necessary to first check the overall situation of the device to ensure that it can work properly. According to Figure 1 - Figure 6 As shown, use the thumb of one hand in cooperation with the ring finger, and the index finger and middle finger respectively pull the two movable rods 215 to move outwards, so that the clamping head 217 is withdrawn from the clamping groove 213. Then use the other hand to push the moving sleeve 208 to move and compress the return spring 210 to contract, so that the locking ball 207 is separated from the trapezoidal block 211, and then the trapezoidal block 211 can freely rise and fall. Then release the movable rod 215. The first spring 216 pulls the movable rod 215 to move and makes the clamping head 217 engage with the clamping groove 213, so that the moving sleeve 208 maintains the position of compressing the return spring 210. At this time, pull the first docking sleeve 201 and the second docking sleeve 202 apart to realize the quick separation of the two pipeline bodies 1. Similarly, the quick installation of the two pipeline bodies 1 can also be realized, avoiding the need for a lot of time and complex operations such as gluing during docking;

[0036] The sealing ring 203 is tightly attached to the first docking sleeve 201 and the second docking sleeve 202, so that there is good airtightness at the connection of the pipeline.

[0037] Filter the dust in the air-conditioning duct through the separator net 302, draw it out from the bent rod 301 through the movable lever 306, and then remove the separator net 302 from the second docking sleeve 202. With the cooperation of the docking assembly 2, the separator net 302 can be quickly cleaned, so that the amount of dust in the cold air ejected by the automotive air-conditioning system is further reduced.

[0038] Although the present 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
