Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific examples.

As shown in fig. 1 to 8, the high pressure air pump vibration-damping and noise-reducing accessory of the present invention comprises an accessory body 1, wherein the accessory body 1 comprises two vibration-damping devices 2, each vibration-damping device 2 comprises a vibration-damper 3 and a frame 4, the vibration-damper 3 is fixedly connected with the frame 4, the vibration-damper 3 comprises a vibration-damping layer 5, a first noise-reducing layer 6 and a second noise-reducing layer 7, the vibration-damping layer 5 is fixedly connected with the second noise-reducing layer 7 through the first noise-reducing layer 6, a plurality of telescopic rods 8 are installed in the vibration-damping layer 5, a fixing rod 9 is installed in the middle of each adjacent telescopic rod 8, the middle lower parts of the adjacent telescopic rods 8 are connected through a first spring 10, the inner wall of the vibration-damping layer 5 is connected with the fixing rod 9 through a second spring 11, a hole 12 is opened at the intersection of each adjacent fixing rod 9, rails 13 are opened, the lower part damping device 2 both sides are installed the elasticity piece 19, elasticity piece 19 includes knob 15, knob 15 passes through fixed block 18 and damping device 2 threaded connection, fixed block 18 passes through connecting rod 16 and lug 17 fixed connection. Noise generated by the high-pressure air pump sequentially passes through the shock absorption layer 5, the first noise reduction layer 6 and the second noise reduction layer 7, and the noise is effectively weakened, so that low-decibel sound is achieved; the motor and the outer side of the impeller shell are provided with concave-convex structures, the telescopic rod 8 can be automatically adjusted according to the concave-convex structures, the concave-convex structures are completely adapted, when the motor works to generate vibration, the first spring 10 can reduce the vibration in the horizontal direction, the second spring 11 can reduce the vibration in the vertical direction, the high-pressure air pump can stably run after multidirectional vibration reduction, and the working efficiency of the high-pressure air pump is improved; when high compression pump breaks down, can be separately two damping device 2 through opening of elasticity piece 19, then maintain, put into the damping device 2 of downside after high compression pump repaiies in, then align and cover the damping device 2 of upside, inwards rotate knob 15, thereby fixed block 18 drives lug 17 and rotates, rotate to stall behind the joint with recess 14 as lug 17, elasticity effect through elasticity piece 19 can further reduce vibrations, and then the stability of reinforcing high compression pump during operation, convenient and efficient in use, the practicality is good.
