Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 3, an air pump with a vibration damping device includes a case 10, an air pump body 20, an adjusting assembly 30, a damping assembly 40, and a limiting assembly 50. The top surface of the case 10 is opened. The air pump body 20 is fixedly installed on the top end surface of the buffer plate 45. The air pump body 20, the adjusting assembly 30 and the shock-absorbing assembly 40 are all disposed inside the cabinet 10. The adjusting assembly 30 comprises a bidirectional threaded screw rod 31, one end of the bidirectional threaded screw rod 31 is rotatably connected with the case 10 through a bearing seat, sliding nuts 32 are respectively slidably mounted at left-handed threads and right-handed threads formed in the surface of the outer wall of the bidirectional threaded screw rod 31, clamping rings 33 are respectively fixedly mounted at the top ends of the two sliding nuts 32 through connecting rods 34, and the clamping rings 33 are slidably mounted outside the sliding rods 41.
When adjusting first spring 42 pretightning force, only need rotatory adjust knob, can drive two-way screw lead screw 31 and rotate, then can drive two sliding nut 32 and be close to each other or keep away from the removal each other in two-way screw lead screw 31 outside, can drive clamp ring 33 through connecting rod 34 simultaneously and remove, when two clamp ring 33 are close to the removal each other, can realize the compression to first spring 42 through clamp ring 33, can shorten the length of first spring 42, then can improve the elasticity of first spring 42, thereby adjust in a flexible way according to the air pump vibration degree of reality, guarantee the steady operation of air pump.
When the air pump body 20 works to generate vibration, the buffer plate 45 can be driven to move up and down, the buffer plate 45 drives the sliding sleeve 43 to transversely slide through the support rod 44 in the vertical lifting process of the buffer plate 45, and the sliding sleeve 43 slides along the sliding rod 41 at the moment, so that the first spring 42 can be compressed, namely, the air pump generates elastic vibration reduction.
Wherein, spacing subassembly 50 includes limiting plate 51, and limiting rod 52 is fixed mounting in limiting plate 51 top, and the outside cover of limiting rod 52 is equipped with second spring 53.
The buffer plate 45 is slidably connected to the limit rod 52, and the second spring 53 is located at the upper end of the buffer plate 45. When air pump body 20 produced the vibration, on vibration transmission reached buffer board 45, buffer board 45 was vertical reciprocates under the elastic action of second spring 53 for gag lever post 52 relatively, played the buffering damping effect to the air pump body, did benefit to the even running of guaranteeing the air pump body, and limiting plate 51 of setting can play the spacing effect of descending to buffer board 45, and the displacement range of avoiding buffer board 45 is too big. The limiting plate 51 is fixedly installed on the inner wall surface of the case 10. One end of the bidirectional threaded screw rod 31 extends to the outside of the case 10 and is fixedly provided with an adjusting knob. Because the adjusting knob is arranged on the outer side of the case 10, people can conveniently rotate the adjusting knob, and the use convenience is improved.
The specific using process is as follows: when adjusting first spring 42 pretightning force, only need rotatory adjust knob, can drive two-way screw lead screw 31 and rotate, then can drive two sliding nut 32 and be close to each other or keep away from the removal each other in two-way screw lead screw 31 outside, can drive clamp ring 33 through connecting rod 34 simultaneously and remove, when two clamp ring 33 are close to the removal each other, can realize the compression to first spring 42 through clamp ring 33, can shorten the length of first spring 42, then can improve the elasticity of first spring 42, thereby adjust in a flexible way according to the air pump vibration degree of reality, guarantee the steady operation of air pump.
