Description

Convenient window glass bidirectional scraper

Technical Field

The utility model relates to a window wiper, in particular to a convenient window glass bidirectional wiper.

Background

There are many window cleaners on the market, which can be roughly classified into three types: one type of the structure is a straight rod structure, when the structure is used for scrubbing outside window glass, a body needs to be extended out of the window, and the potential safety hazard is large; the other type is improved on the basis, an L-shaped crank is connected to the holding end of the straight rod, when the structure is used for scrubbing outside window glass, the crank is held by hand for operation, a body does not need to be extended out of a window, but the bottom end (the other end provided with the scrubbing head) of the structure has large interference with an operation environment, the structure is only suitable for large-area window glass and places with wide space, the horizontal opening degree of the window glass of a household is generally smaller than 80 cm, and the window frame is close to a window sill and has short distance with two side walls, so that the structure is difficult to be developed during operation; the other type is a magnetic clamping plate type window cleaner, but the operation difficulty is higher, the window cleaner is suitable for trained professional cleaning personnel, even if the window cleaner is used, the wiping component (even though a rope is hung on the hand) outside the window is not always dropped, and serious potential safety hazards are caused to downstairs pedestrians.

Disclosure of Invention

In order to overcome the defects of convenience, safety, easy operability and applicability of the existing products in use, the popular convenient window glass wiper with convenient use, high safety, low operation technical threshold and wide application range needs to be provided.

The utility model provides a technical scheme that its technical problem adopted is: a portable windowpane bi-directional squeegee comprising: a wiping scraper, a U-shaped bracket and a lifting handle.

The scraping plate comprises a substrate, a scraping strip, a wiping felt, a bearing assembly and a return spring; the substrate is of a rectangular structure; one surface of the substrate is respectively embedded with a rubber scraping strip along two long edges, and the other surface is respectively provided with two groups of bearing assemblies at the positions close to the two ends of the long symmetrical shaft and takes the long symmetrical shaft as the axial direction; the wiping felt is arranged between the two scraping strips and is in an elliptical tube shape, and the wiping felt is attached to the base plate by using a magic tape nylon buckle; two return springs are arranged on one of the shafts in the direction of the opposite force.

The U-shaped bracket comprises an integrated U-shaped pipe, an extension pipe locking piece and a pipe hoop bracket; one arm of the integrated U-shaped pipe is connected with a section of telescopic pipe by using a telescopic pipe locking part, and the end part of the other arm is provided with a round hole; the pipe hoop support is fixed at the two ends of the telescopic pipe close to the two ends through the pipe hoop, the support end of the pipe hoop support is connected with a bearing assembly at the back of the base plate, and the base plate can deflect along the axis in two directions.

One end of the lifting handle is provided with a groove-shaped connector, and the width of the groove is slightly larger than the diameter of the U pipe; the two side plates of the groove are provided with connecting circular holes.

Further, the length of the wiping blade is between 30 and 50 centimeters, and the width of the wiping blade is between 4 and 8 centimeters.

Furthermore, the external convex surface of the elliptical tubular wiping felt is slightly higher than the knife edge of the wiping strip by 2-3 mm in a natural state, and can generate elastic deformation when being pressed.

Furthermore, the distance between the center of the connecting hole on the groove-shaped connector and the bottom of the groove is 3-6 mm larger than the radius of the integrated U pipe, and the width of the groove is 2-5 mm larger than the diameter of the U pipe (9).

Furthermore, the scraping plate is fixed on the telescopic pipe, and the telescopic pipe is adjusted to meet the requirement of a wider glass window.

The utility model has the advantages that: when the outer side of the window glass is wiped, one arm of the U-shaped bracket is positioned on the inner side of the window, an operator holds the arm to operate, the body does not need to stretch out of the window completely, and the whole device is of an integrated structure, so that the device cannot fall off to endanger downstairs and can effectively solve the safety problem; the scraping strips are distributed on two sides of the wiping felt, so that the sequence of first wiping and then scraping can be ensured no matter the wiping scraper scrapes upwards or downwards, and in addition, the sequence of first wiping and then scraping can also be ensured no matter the U port of the U-shaped bracket is horizontally inserted from the right side or the left side of the window glass without any adjustment; because the structure is compact, the wiping scraper can move up and down in a horizontal state in the wiping working process, so that the interference with buildings around the window is less, and the device is also suitable for the outward-pushing type glass window; in addition, the operating technology threshold is low, and most people can adapt to the operating technology.
