Description

Technical Field

[0001] This utility model relates to the field of eccentric wheels, specifically a wear-resistant eccentric wheel. Background Technology

[0002] An eccentric wheel, as the name suggests, is a wheel whose center is not at the point of rotation. It generally refers to a circular wheel. When a circle does not rotate around its own center, it becomes an eccentric wheel. An eccentric wheel is also a type of cam. Generally speaking, the main purpose of an eccentric wheel is to generate vibration. Electric sieves and vibrators in mobile phones use eccentric wheels. Most eccentric wheels are circular because they are easy to manufacture and have a simple process. In order to improve the service life of eccentric wheels, the surface of current eccentric wheels is treated with wear-resistant materials to extend their service life.

[0003] Existing eccentric wheels often suffer from the problem of not being able to adjust the eccentric distance during use. When it is necessary to adjust the eccentric amplitude, the eccentric wheel can only be disassembled and then a new eccentric wheel with an appropriate eccentric amplitude can be installed, which is time-consuming and laborious and not conducive to the use of the eccentric wheel. Therefore, a wear-resistant eccentric wheel is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and solve the problem that the wear-resistant eccentric wheel is not easy to adjust the eccentric distance, this utility model proposes a wear-resistant eccentric wheel.

The surface of the limiting sleeve is fixedly connected to the pull plate. An insert block is fixedly connected to the surface of the pull plate, and one end of the insert block extends into the inner cavity of the slot.

[0006] Preferably, the surface of the movable sleeve is provided with a mounting hole, and the inner cavity of the mounting hole is provided with a rotating shaft, both ends of which extend to the outer side of the eccentric wheel housing.

[0018] Reference Figure 2 , Figure 3 and Figure 4The surface of the movable sleeve 2 is provided with a mounting hole 6, and a rotating shaft 7 is provided in the inner cavity of the mounting hole 6. Both ends of the rotating shaft 7 extend to the outer side of the eccentric wheel housing 1. Six positioning strips 8 are fixedly connected to the surface of the rotating shaft 7.

[0021] Working principle: The user installs the rotating shaft 7 into the movable sleeve 2 and then uses the entire eccentric wheel. When it is necessary to adjust the eccentric distance of the entire eccentric wheel, the user can first pull the lifting ring 508. The lifting ring 508, through the cooperation of the pull plate 501, drives the limiting sleeve 505 to compress the spring 506. At the same time, the pull plate 501 drives the insert block 507 to move out of the slot 4, which can release the fixation between the eccentric wheel housing 1 and the movable sleeve 2. At this time, the position of the movable sleeve 2 in the inner cavity of the eccentric wheel housing 1 can be adjusted. After the adjustment is completed, the lifting ring 508 is released. At this time, the spring 506 returns to its original position and, through the cooperation of the limiting sleeve 505 and the pull plate 501, drives the insert block 507 to insert into the slot 4, fixing the movable sleeve 2. By adjusting the position of the movable sleeve 2 in the inner cavity of the eccentric wheel housing 1, the eccentric distance of the entire eccentric wheel can be quickly adjusted, making it convenient for use in different environments.
