Magnetism adjusting device mounted on body of magnetic glass wiper

Abstract

The invention discloses a magnetism adjusting device mounted on a body of a magnetic glass wiper. The device comprises a body bottom housing, a rear cover and a magnet, a magnet holder and an iron sheet which are arranged inside the bottom housing, wherein the bottom housing and the rear cover form a chamber; a guide column is arranged in the chamber which is formed by the rear cover and the bottom housing and used for moving the magnet, the magnet holder and the iron sheet up and down in a balanced manner; a shifting key is arranged on the upper end surface of the rear cover; a stepped adjusting rod is arranged below the shifting key; a slider is fixed at the lower end of the stepped adjusting rod; the slider is arranged on the bottom housing on which a sliding chute is formed; and notches through which the stepped adjusting rod passes are formed the magnet holder and the iron sheet. The magnetism adjusting device has a simple structure, is convenient to operate, keeps the magnet holder and the iron sheet in balance and smooth during motion, and prevents the problems of warping and turning. Besides, the range of adjusting the magnetic attraction force is large and the operation is safe.

Description

technical field [0001] The invention relates to a magnetic glass wiper, more specifically to a magnetic adjustment device on the wiper body of the magnetic glass wiper. Background technique [0002] Magnetic glass wipes have been widely used in the cleaning of glass doors and windows. For glass doors and windows of different thicknesses, people either use glass wipes of different magnetic suction models, or use glass wipes with adjustable magnetic force, as disclosed by the applicant before this. The patent number is 200720126485.4, and the name is a magnetic double-sided glass wiper with adjustable magnetic attraction. This magnetic adjustment method is to adjust the size of the magnetic attraction by replacing the backing plate with different thickness, which is very cumbersome to adjust. Another patent published by the applicant before this, the patent number is 200820029385.4, the name is a magnetic double-sided glass wiper with adjustable magnetic attraction force. To ...

Problems solved by technology

The problem of this kind of magnetic adjustment structure based on the spiral principle is: when adjusting the magnetic force, the magnet device is easy to tilt, and it is easy to swing when pulling. After attracting each other, after the pulling test of the main and auxiliary rubbing bodies, it is determined that the appropriate magnetic force is adjusted. It is very cumbersome to adjust, and it is difficult to determine whether it is adjusted properly.

When the magnetic force is adjusted to the maximum or the maximum, the magnetic force cannot be quickly controlled to the minimum. Due to the strong magnetic force, when the main and auxiliary wipers are too close to each other in the non-working state, it is very easy for the glass wiper to get caught and it is difficult to open.

This kind of magnetic adjustment structure can adjust the range of magnetic attraction force is small. If you want to increase the range of magnetic adjustment, you must increase the overall thickness of the main wiper, which is not practical.
