Description

A kind of vehicle wiper

Technical field

The utility model relates to a kind of vehicle wiper.

Background technology

Existing wiper normally arranges a spring at drive spindle terminal position place, predetermincd tension by this spring is against wiper bar on vehicle glass mutually, in actual practical process, the predetermincd tension of this spring is usually inadequate, or period of service has been grown, spring failure, has caused the wiper can not effective cleaning windshield, at this moment just need labor cleaning, very inconvenient.

Summary of the invention

The technical problems to be solved in the utility model is to provide one can pass through manual adjustment, makes cleaning capacity stronger, simultaneously the vehicle wiper of longer service life.

For addressing the above problem, the utility model adopts following technical scheme:

A kind of vehicle wiper, comprise drive spindle and wiper bar, between described wiper bar middle part and drive spindle top, be connected with bearing pin, on the shaft of described drive spindle, be provided with a chute, be provided with a tapped bore in this chute one side, and be combined with a screw by this tapped bore, described chute opposite side is combined with a retracing spring, in described chute, be combined with a backing block, described retracing spring and this backing block offset, described screw end has the clamping part of " ten " font, described backing block matches with described clamping part, described screw is fixed with a rubber cushion through on that one end of screw hole, described rubber cushion and wiper bar offset.

As preferred technical scheme, described backing block has the bayonet socket of a rectangle, and this bayonet socket matches with clamping part, and the height of described bayonet socket is 1mm-1.5mm, and the height of described clamping part is 5mm-15mm.

As preferred technical scheme, described rubber cushion is semisphere, and its that one end and wiper bar with spherical offsets, and its flat end is glued on screw end face.

As preferred technical scheme, the length after described retracing spring launches is not less than the length of chute.

As preferred technical scheme, described chute is for falling " T " font groove, and described backing block bottom has the slide block matching with this chute, and slide block and backing block are integral type.

The beneficial effects of the utility model are: in use, can manual rotation screw, under the application force of screw, open the angle between drive spindle and wiper bar, make wiper bar can tightly be fitted in the surface of windshield, increase the dirt-removing power of wiper, can prevent loosened screw by backing block simultaneously, make this device in use without carrying out secondary adjusting, simple and convenient, be applicable to promoting the use of.
