Embodiment 1

[0018] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, an eccentric block for a vibration motor includes a fixed eccentric block 1 and a movable eccentric block 2 sleeved on the rotating shaft 4 of the vibration motor. The limit adjustment block 3 on the 4, the limit adjustment block 3 is disc-shaped, and the positioning pin 5 capable of blocking the rotation of the movable eccentric block 2 is arranged on the limit adjustment block 3 disk surface. The limit adjustment block 3 is set between the fixed eccentric block 1 and the movable eccentric block 2. The limit adjustment block 3 and the fixed eccentric block 1 are connected to the rotating shaft 4 through the key 7. The outside of the fixed eccentric block 1 is positioned by the snap spring 6, and the fixed eccentric block Block 1 can be designed as figure 2 As shown, an opening is set on the fixed eccentric block 1, which is connected by screws 11 for easy installation; both the fixed eccentric block 1 a...

Embodiment 2

[0021] Such as Figure 5 As shown, the fixed eccentric block 1 is provided with a plurality of filling holes 12, and the movable eccentric block 2 is provided with a plurality of filling holes 22; the others are the same as in the first embodiment. In this embodiment, the mass and center of mass of the eccentric mass can be changed by adding fillers in the filling hole 12, so as to change the vibration effect produced by the eccentric mass when it participates in the vibration, and the adjustment is convenient and flexible.

[0022] In the present invention, both the fixed eccentric block and the movable eccentric block can be composed of multiple stacked pieces or have filling holes on them, or other similar methods can be used to change the mass and center of mass of the eccentric block.

Abstract

The invention discloses an eccentric block for a vibrating motor, which comprises a fixed eccentric block and a movable eccentric block which are in sleeve joint on a rotating shaft of a vibrating motor, wherein the fixed eccentric block and the movable eccentric block are in a fan shape. The eccentric block for the vibrating motor also comprises a limiting and regulating block which is fixedly in sleeve joint on the rotating shaft, wherein the limiting and regulating block is in the shape of a circular disk, and a positioning pin which can be used for obstructing the rotation of the movable eccentric block is arranged on the disk face of the limiting and regulating block. According to the eccentric block for the vibrating motor, the vibrating force and the vibrating amplitude can be freely regulated, the regulation is convenient and flexible, and various vibrating effects can be generated by the vibrating motor.

Description

technical field [0001] The invention relates to an eccentric block for a vibration motor. Background technique [0002] At present, many vibrations generated in vibration equipment, vibration motors, and vibration machinery are generated by eccentric rotation to generate vibration force. However, the eccentric part is fixed on the rotating shaft during operation, the vibration force and amplitude cannot be adjusted during operation, and the vibration effect is single. Contents of the invention [0003] The purpose of the present invention is to provide an eccentric block for a vibration motor which is convenient for adjusting the vibration effect. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] An eccentric block for a vibration motor, including a fixed eccentric block and a movable eccentric block sleeved on the rotating shaft of the vibration motor, the fixed eccentric block and the movable eccentric blo...
