[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the present utility model embodiments.

[0030] Example 1

[0031] like Figures 1-4As shown, this utility model provides a technical solution: a sealing structure for a drying cylinder of an automotive air conditioner condenser, including a drying cylinder body 1, a sealing connection mechanism 2 installed at the top of the drying cylinder body 1, the sealing connection mechanism 2 including a fixing seat 201, the fixing seat 201 being welded to the top of the drying cylinder body 1, fixing blocks 202 being symmetrically welded on the left and right sides of the fixing seat 201, a clamping block 203 being installed on the front of the fixing block 202 near the outer side, a limiting rod 204 being slidably connected to the back of the clamping block 203 near the corner of the lead screw and passing through the back of the fixing block 202, a connecting pipe 205 being installed between the inside of the fixing block 202 and the clamping block 203, fixing components 206 being installed inside both the fixing block 202 and the clamping block 203, and a limiting component 207 being installed on the outer side of the fixing block 202.

[0032] Example 2

[0033] like Figures 1-4As shown, a channel 2011 is provided inside the fixing base 201, extending through the bottom. The channel 2011 is connected to the main body 1 of the drying cylinder. The channel 2011 extends through the left and right sides of the fixing base 201 and is connected to the connecting pipe 205. The external refrigerant flows through the left connecting pipe 205, through the channel 2011, into the main body 1 of the drying cylinder, and flows out through the right connecting pipe 205 via the right channel 2011. The fixing base 201, fixing block 202, and clamping block 203 are all made of stainless steel, and their surfaces are nickel-plated. Stainless steel has strong corrosion resistance, and the nickel plating treatment can improve its surface wear resistance, thereby improving the performance of the fixing base 201 and fixing block 202. 2. To extend the service life of the clamping block 203, the limiting rod 204 extends to one end of the back of the fixing block 202 and is threadedly connected to a nut 2041. By rotating the nut 2041, the limiting rod 204 can be fixed, thereby preventing the clamping block 203 from loosening and improving the fixing effect on the connecting pipe 205. A sealing ring is welded to the inner end of the connecting pipe 205 where it fits against the fixing block 202. The sealing ring can improve the sealing effect between the connecting pipe 205 and the fixing block 202. The fixing component 206 includes a threaded rod 2061, which is threadedly connected to the corresponding fixing block 202 or clamping block 203. The threaded rod 2061 is close to the fixing seat 201. A pressure plate 2062 is rotatably connected to the end of the connecting pipe 205. The pressure plate 2062 abuts against the connecting pipe 205. By rotating the threaded rod 2061, the pressure plate 2062 can be moved inward, thereby cooperating with the fixing block 202 to fix the connecting pipe 205, making its connection with the channel 2011 tighter. The pressure plate 2062 is made of semi-circular stainless steel, and its inner side, where it contacts the connecting pipe 205, is engraved with anti-slip texture. The anti-slip texture can enhance the friction between the pressure plate 2062 and the connecting pipe 205, thereby improving the fixing effect. The limiting component 207 includes two arc-shaped retaining rings 2071. The top and bottom of the back of the arc-shaped retaining rings 2071 are symmetrically welded with connecting... Rod 2072, the end of connecting rod 2072 away from the arc retaining ring 2071 is welded to the corresponding fixing block 202 or clamping block 203. The outer side of the arc retaining ring 2071 extends to the inner side and is threadedly connected to a fixing rod 2073. The inner side of the fixing rod 2073 is rotatably connected to an arc-shaped fixing piece 2074. The arc-shaped fixing piece 2074 abuts against the connecting pipe 205. By rotating the fixing rod 2073, the arc-shaped fixing piece 2074 can be moved inward, thereby clamping and fixing the periphery of the connecting pipe 205, extending the fixing range of the connecting pipe 205, and reducing the loosening effect caused by vibration at the connection between the connecting pipe 205 and the channel 2011.

[0034] The working process of this utility model is as follows: When connecting and using a sealing structure for a car air conditioning condenser dryer cylinder, firstly, the connecting pipe 205 is embedded inside the fixing block 202 and tightly fitted. Then, the clamping block 203 is pushed backward, and the outer periphery of the connecting pipe 205 is fitted inside the limiting component 207. After the clamping block 203 and the fixing block 202 are fitted, the nut 2041 is rotated, and the clamping block 203 is fixed by the limiting rod 204. At the same time, the threaded rod 2061 is rotated, causing the pressure plate 2062 to move inward, which, together with the fixing block 202, clamps and fixes the connecting pipe 205. Finally, the fixing rod 2073 is rotated, causing the arc-shaped fixing plate 2074 to clamp and fix the periphery of the connecting pipe 205, thus completing the entire connection process. Compared with the traditional nut fixing method, this method can extend the fixing range of the connecting pipe, reduce the impact of vibration on the connection between the connecting pipe 205 and the channel 2011, greatly improve the connection stability, and effectively improve the sealing effect.
