DETAILED DESCRIPTION

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.

Please refer to Figures 1-4, a low-noise screw air compressor includes a box body 1, a screw air compressor device 6, a bottom plate 5 and a cross bar 15. The front end of the box body 1 is provided with a baffle 3, the interior of the box body 1 is provided with a cavity 2, the inner wall of the cavity 2 is provided with a sound insulation board 4, the cross bar 15 is fixed to the bottom of the cavity 2, both ends of the cross bar 15 are provided with a detachable positioning shaft 7, the positioning shaft 7 is provided with a positioning seat 8, the bottom plate 5 and the screw air compressor device 6 are both located inside the cavity 2, the screw air compressor device 6 is fixed to the upper end of the bottom plate 5, the bottom plate 5 A damping rod 11 penetrating the positioning seat 8 is provided at the lower end thereof, and a spring 10 penetrating the damping rod 11 is provided between the base plate 5 and the positioning seat 8. The screw air compressor device 6 is fixed on the base plate 5. When the screw air compressor device 6 vibrates, the base plate 5 drives the damping rod 11 to reciprocate and descend. There is a certain friction force between the damping rod 11 and the positioning seat 8. At this time, the damping rod 11 will be continuously compressed. The damping rod 11 can provide a shock absorbing effect to the base plate 5, and the sound insulation board 4 can provide a noise reducing effect to the screw air compressor device 6 when in use.

When the spring 10 is damaged, the bottom plate 5 is lifted upwards, and the damping rod 11 can be pulled out on the positioning seat 8. At this time, the spring 10 can be disassembled. The structure is simple and easy to operate, which can shorten the time spent on maintenance of the structure and improve the maintenance efficiency.

The threaded connection method can make the positioning shaft 7 easy to disassemble. The threaded connection method has the advantage of easy assembly, and can make the positioning shaft 7 easy to assemble at both ends of the cross bar 15.

When the parts on the cross bar 15 are damaged, the cross bar 15 needs to be disassembled. A positioning plate is provided at the lower end of the fixing seat 9, and the positioning plate is fixed to the bottom of the cavity 2 by screws.
