[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3The utility model provides a filter drier with an impact-resistant structure, comprising a filter drier body 1, butt-joint pipes 2 being symmetrically arranged at both ends of the filter drier body 1, a protective sleeve 4 and a reinforcing sleeve 9, a plurality of reinforcing ribs 3 being arranged on the outer wall of the filter drier body 1, the protective sleeve 4 being penetrated by the filter drier body 1, the reinforcing sleeve 9 being fixed at both ends of the protective sleeve 4, and a protective tube 10 being penetrated by the butt-joint pipe 2 being arranged at the outer end of the reinforcing sleeve 9;

[0023] In this structure, the reinforcing ribs 3 and the dry filter body 1 are formed by an integrated stretching process. The plurality of reinforcing ribs 3 can increase the rigidity and impact resistance of the overall structure of the dry filter body 1.

[0024] By means of the two reinforcing sleeves 9, the contact strength between the butt joint pipe 2 and the filter drier body 1 can be improved, so that the butt joint pipe 2 and the filter drier body 1 are not easily broken after being subjected to force. When the filter drier body 1 falls or is impacted, the impact force will be transmitted to the protective sleeve 4 and the reinforcing sleeve 9, and will not be directly transmitted to the filter drier body 1 or the butt joint pipe 2. At this time, the protective sleeve 4 or the reinforcing sleeve 9 will be damaged first, so that it is not easy to damage the desiccant inside the filter drier body 1 or cause the filter drier body 1 to leak, which can further improve the service life of the filter drier body 1.

[0025] Furthermore, the protective sleeve 4 and the reinforcing sleeve 9 are both fitted with the dry filter body 1 , so that the protective sleeve 4 and the reinforcing sleeve 9 can be installed on the dry filter body 1 more firmly.

[0026] The lack of a positioning structure between the reinforcement sleeve 9 and the docking ring 5 will make the reinforcement sleeve 9 not installed firmly. The docking rings 5 ​​are fixedly arranged at both ends of the protective sleeve 4. The circumferential side of the docking ring 5 is provided with a plurality of slots 6. The circumferential side of the reinforcement sleeve 9 is provided with a plurality of blocks 11 that cooperate with the slots 6. Through the cooperation of the blocks 11 and the slots 6, a positioning structure can be provided between the reinforcement sleeve 9 and the docking ring 5, which can make the reinforcement sleeve 9 installed more firmly.

[0027] Furthermore, the peripheral side of the reinforcing sleeve 9 is bonded to the docking ring 5, and the bonding method has the advantage of convenient assembly.

[0028] Furthermore, the protective sleeve 4 and the reinforcing sleeve 9 are both made of plastic material. Hard plastic has high hardness and strength, can withstand greater pressure and impact, and is not easily deformed or broken.

[0029] Furthermore, a plurality of grooves 7 cooperating with the reinforcing ribs 3 are provided on the inner wall of the protective sleeve 4, and a protective pad 8 is provided on the inner wall of the groove 7. When the protective sleeve 4 is installed, the rubber protective pad 8 is squeezed, thereby increasing the friction between the protective sleeve 4 and the dry filter body 1, and making it easier to position the protective sleeve 4 on the dry filter body 1.
