Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Example 1: referring to fig. 1-3, the load-bearing cushion comprises a main body 41, a channel 42 is axially arranged through the main body 41, a support ring 44 is arranged at the lower end of the main body 41, an annular groove 45 is arranged on the outer surface of the main body 41 near the upper end, and a deformation damping part 43 is convexly arranged on the inner wall of the main body 41 between the annular groove 45 and the support ring 44.

Furthermore, a plurality of buffering bosses 46 are uniformly distributed on the inner wall of the support ring 44, and the bottom surfaces of the buffering bosses 46 and the bottom surface of the support ring 44 are both arc-shaped surfaces or conical surfaces. The buffer boss 46 can reduce the contact area, play a role in buffering, and has a better buffering effect relative to a plane by adopting an arc surface or a conical surface.

Further, the compression deformation amount L of the deformation cushioning portion 43 is 1.5 to 2.5 mm.

More preferably, the compression deformation amount L of the deformation damper 43 is 2 mm.

Further, the bearing shock pad 4 is made of rubber with the hardness of 80HS, and the bearing shock pad 4 is installed on the water pump fixing frame, so that the product has certain elasticity and certain bearing hardness.

For further explaining the application of the present invention, referring to fig. 4-8, the water pump and housing damping structure of a water purifier comprises a housing 1, a water pump 2, a nut sleeve 3, a bearing damping pad 4 and a screw rod 5, wherein two sides of the bottom of the water pump 2 are respectively provided with a fixing bracket 21, the fixing bracket 21 is provided with a bracket mounting hole 210, the inner bottom of the housing 1 is provided with a mounting hole 11,

the bearing shock-absorbing pad 4 is pre-installed in the bracket mounting hole 210,

the nut sleeve 3 comprises a nut sleeve body 31 and a nut cap 32, the nut sleeve body 31 is connected with the channel 42 in a sliding mode, internal threads 33 are formed inside the nut sleeve body 31, and the shell 1 penetrates through the mounting hole 11 from bottom to top through the screw 5 to be connected with the internal threads 33.
