Description
Technical field
The utility model is related to the burnishers of household cleaning apparatus, and in particular to clean the magnetic force double-side window-cleaning of glass
Device.
Background technology
Multiple supporting points of the outer casing bottom of magnetic glass wiper currently on the market are supported on glass when cleaning glass
Surface sliding can be often worn out, and be worn away using several fulcrums of a period of time outer casing bottom, it is easy to be mingled with silt scuffing
Glass, frictional resistance can also increase, and clean more laborious.4 of the outer casing bottom of current all magnetic glass wipers
It is overall structure that supporting point, which is all with shell, and the completely worn out entire shell of supporting point is eliminated.The worker that especially keeps a public place clean uses
Magnetic glass wiper takes very much, and the service life of magnetic glass wiper is shorter.
Invention content
Technical problem
The utility model is intended to overcome shortcoming present in above-mentioned technology, provides a kind of magnetic force that can replace fulcrum
Window-cleaning device, have the characteristics that it is with long service life, fulcrum material use novel high polymer material after can also reduce frictional resistance,
It cleans lighter.
Technical solution
What the technical solution that the utility model solves was realized in：
A kind of interchangeable fulcrum for magnetic glass wiper includes mainly the shell being made of upper cover 1 and lower casing 2, shell
Interior installation permanent magnet 3 and magnetic conductive board 4,2 outside of lower casing are arranged felt 5 and scrape glue item 6, it is characterized in that：Magnetic glass wiper
Multiple mounting holes 8 are arranged in 2 middle part of lower casing, and interchangeable fulcrum 7, interchangeable fulcrum 7 and 8 secure fit of mounting hole are installed in mounting hole 8, can
It fills detachable.
The shock ring 3 of 8 surrounding of the mounting hole setting corrugated concentric circles for installing interchangeable fulcrum 7.
The interchangeable fulcrum 7 is cylinder or polygon prism.
The interchangeable fulcrum 7 is Step Shaft, and one end is large diameter round table 9, and one end is that locating journal 10 is fixed with mounting hole 8
Cooperation.
Top surface setting chamfering, circular arc or the lock projection crest line of the interchangeable fulcrum 7.
The material of the interchangeable fulcrum 7 is the lower high molecular material of friction coefficient or composite material between glass.
The mounting hole 8 for installing interchangeable fulcrum 7 is blind hole or through-hole.
Elastic plastic-rubber pad 11 is set between the interchangeable fulcrum 7 and mounting hole 8.
Advantageous effect
The interchangeable fulcrum of the magnetic glass wiper of the utility model has the advantages that：
1. service life is long.Four supporting points of outer casing bottom the more grind the more thin, and support is just lost after grinding off completely and is made
With becoming large area friction, it is easy to be mingled with silt and scratch glass, frictional resistance can also increase, and shell should be scrapped.This reality
The supporting point structure for making into replace with novel supporting point after supporting point is seriously worn, does not have to entire shell report
It destroys, changing supporting point can be continuing with, and substantially prolong the service life of shell.It is more suitable for housekeeping to keep a public place clean public affairs
Department uses.
2. cleaning light.Interchangeable fulcrum can be different from the material of lower casing, therefore can select more resistant more smooth low
The high molecular material or composite material of friction coefficient.Service life is allowed to extend, frictional force can also reduce, and clean lighter.
3. damping and silencing.Shock ring can be set around interchangeable supporting point, and the structure of shock ring can be concentric circles
Corrugated shape, shape be similar to sound equipment loudspeaker vibrations membrane structure, be also similar to that the concentric circles wave-like of ripples, can more than
It is lower that certain deformation occurs, bumper and absorbing shock can be played the role of when by impacting, played a protective role to glass, while sound
Sound can also reduce.

Specific implementation mode
The utility model is further described in detail in conjunction with attached drawing.
Most preferred embodiment：
As depicted in figs. 1 and 2, it is a kind of lower casing of magnetic glass wiper, includes the shell being made of upper cover 1 and lower casing 2,
Installation permanent magnet 3 and magnetic conductive board 4 in the shell of magnetic glass wiper, 2 outside of lower casing are arranged felt 4, felt pressure plate 5 and scrape glue
Item 6, it is characterized in that：Multiple mounting holes 8 are arranged in 2 middle part of lower casing, and interchangeable fulcrum 7 is installed in mounting hole 8.
The position of mounting hole 8 and interchangeable fulcrum 7 is set as needed, and can be crossing distribution, can also be strip square
Shape is distributed or Triangle-Profile.
Interchangeable fulcrum 7 is cylinder or polygon prism, as shown in Fig. 2, support platform 9 is support round table surface, and glass contact,
Periphery carries chamfering and knuckle.The locating journal 10 of outside diameter can be inserted in mounting hole 8, to be fixedly mounted on down
2 bottom of shell, is fixed together with lower casing 2.Interchangeable fulcrum 7 can also be Step Shaft.
As shown in figure 3, shock ring 3 is arranged around the interchangeable fulcrum 7 of lower casing 2, the structure of shock ring 3 is concentric circles
Corrugated shape, shape are similar to the vibrations membrane structure of Music centre loudspeaker, are also similar to that the concentric circles wave-like of ripples, can be outside
Certain flexible deformation occurs under force effect up and down, bumper and absorbing shock can be played the role of when by impacting, protective glass is not
It can be shattered and split, while reduce the sound of vibration.
Interchangeable fulcrum 7 can be unloaded when the abrasion of the support platform 9 of interchangeable fulcrum 7 cannot seriously reuse very much, then is replaced
New interchangeable fulcrum 7 is continuing with.Entirety will not be allowed to scrap because of supporting point excessive wear.
Embodiment 2：
