Description

Double-rubber-strip windscreen wiper

Technical Field

The utility model relates to a wiper technical field, more specifically the utility model relates to a two rubber strip wipers.

Background

Traditional wiper adhesive tape generally is single adhesive tape (single edge of a knife), and the adhesive tape is thick, and easy wearing and tearing moreover scrape and wipe off the noise also big, for solving this technical problem, appeared one kind among the prior art and adopted the wiper of two adhesive tapes, but appeared the adhesive tape easily and lie prone and fall down in the use, and dust is scraped unclean, causes the unclear problem of wiping off the effect of sight poor, and the noise is big. Therefore, how to provide a double-rubber-strip wiper blade with good wiping effect is a problem that needs to be solved by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model aims to provide a two adhesive tape wipers solves current two adhesive tape wipers and lies prone easily and fall down, leads to wiping off the effect poor, the problem that the noise is big.

The utility model provides a two rubber strip wipers, include:

the windscreen wiper rubber strip comprises a silencing strip, a scraping piece and a groveling preventing strip; spring piece mounting grooves are formed on two sides of the bottom of the silencing strip, and two scraping piece mounting grooves which are arranged in parallel are formed on the top of the silencing strip; an upward convex anti-groveling strip is arranged between the two scraping blade mounting grooves, a fixing groove matched with the scraping blade mounting groove is limited at the bottom of each scraping blade, an inclined shoulder is formed at the top of the fixing groove far away from the anti-groveling strip and connected to the knife edge, and a contact area is arranged at the side close to the anti-groveling strip;

the elastic pieces are two groups and are correspondingly arranged in the two scraping piece mounting grooves;

and the water bar is sleeved outside the elastic sheet.

According to the technical scheme, compare with prior art, the utility model provides a two adhesive tape windscreen wipers is provided with the bellied strip of lying prone that makes progress between two doctor-bar mounting grooves, and each doctor-bar is close to the strip side of lying prone and is provided with the contact zone, when wiping away from this, has increased the butt area of doctor-bar with the contact zone, effectively prevents that the doctor-bar from lying prone and falling down, influences the wiping effect, has reduced the doctor-bar and has fallen down the noise that produces.

Further, the top of the anti-groveling strip forms an arc with the radius of 0.1-0.2 mm; the scraping plates on the two sides are in butt joint with the scraping plates, edges and corners do not exist, the scraping continuity is guaranteed, and noise caused by poor contact is reduced.

Furthermore, the scraping blade is positioned at the upper part of the contact area and is in arc transition with the knife edge, the contact area is a plane, and the height of the plane is greater than the height value of the upward bulge of the anti-groveling strip. From this, guarantee that area of contact is enough big, guarantee that the doctor-bar is scraping the in-process butt and on preventing the strip of lying prone, prevent that it from lying prone and falling down and influence and scraping, wherein prevent that the strip material of lying prone selects the material that hardness is greater than the doctor-bar.

Furthermore, the fixed groove is composed of a blocking piece at the top and a sliding piece at the bottom, wherein the length of the side, close to the contact area, of the blocking piece is smaller than that of the other side of the blocking piece; thereby, the blade is facilitated to approach the contact area in wiping, and the abutting area is increased.

Further, the scraping blade is made of natural rubber; the scraper has little hardness change along with the change of temperature, is suitable for being used under the condition of domestic temperature difference climate change, and can not have the problems that the scraper becomes soft along with the high hardness of the temperature and is damaged too early.
