[0024] Example:

[0025] See also Figure 1-5 , the utility model provides a technical solution for a shockproof screw air compressor: comprising a casing 1 and a screw assembly 2;

[0026] A screw assembly 2 is fixed to the right side of the casing 1, and a booster delivery valve 3 is installed to the right side of the screw assembly 2;

[0027] The screw assembly 2 includes a screw assembly inner shell 4 and a protective shell 5. The protective shell 5 includes two upper and lower parts, and the protective shell 5 sandwiches the screw assembly inner shell 4. The two protective shells 5 are installed upside down and fixed downward by bolts after installation.

[0028] The inner cavity of the screw assembly inner shell 4 is provided with a male and female screw 6, the housing 1 is provided with a driving motor, and the left end of the male and female screw 6 is connected to the driving motor through a gear;

[0029] A damping plate 7 is provided on one side of the two protective shells 5 close to the inner shell 4 of the screw assembly. The protective shells 5 are provided with an installation cavity at a position in contact with the damping plate 7. A limiting edge is provided on the outer edge of the damping plate 7, and the limiting edge is clamped on the inner side of the installation cavity.

[0030] The inner cavity of the protective shell 5 is laterally and equidistantly provided with shock absorbing devices 8, which include a base and a shock absorber 82. The base is fixedly installed in the inner cavity of the protective shell 5, the bottom of the shock absorber 82 is welded with the top of the base, and the top of the shock absorber 82 is fixed to the shock absorbing plate 7.

[0031] Air pipes 81 are installed at both left and right ends of the base, and the air pipes 81 are interconnected. A one-way gas valve 84 is installed on the left air pipe 81. The shock absorber 82 includes a damping telescopic sleeve and a damping shock absorbing spring. The damping shock absorbing spring is sleeved on the damping telescopic sleeve. The damping telescopic sleeve and the air pipe 81 are interconnected.

[0032] The top of the shock absorber 82 is fixed with an abutment joint 83, the lower top of the abutment joint 83 is provided with an abutment plate, and the abutment plate is fixed to the shock absorber plate 7 by screws; the middle of the abutment joint 83 is provided with a load-bearing universal ball head, and the load-bearing universal ball head and the top of the telescopic sleeve are fixed to each other;

[0033] The shock absorbing device 8 is symmetrical front and back and is tilted inwards by 30 degrees;
