Hollow windscreen wiper rubber strip

Abstract

The utility model relates to a hollow windscreen wiper rubber strip which comprises a body, a mounting groove is formed in the body, a buffer area is arranged below the mounting groove, an expansion part is arranged below the buffer area, a scraping strip is arranged below the expansion part, the hollow windscreen wiper rubber strip further comprises a cavity, and the cavity penetrates through the expansion part and the scraping strip. After the cavity is added, the deformability of the rubber strip is enhanced, so that the thicker expansion part can be used for replacing the original turnover connecting strip, and the service life is greatly prolonged. In addition, when the windscreen wiper is pressed, the cavity can deform to a certain degree, the windscreen wiper can be attached to the glass more tightly, and wiping is cleaner.

Description

TECHNICAL FIELD

[0001] The present application relates to a hollow wiper rubber strip. BACKGROUND

[0002] Figure 1 In the prior art, a conventional wiper rubber strip is shown, which comprises a body 1, an installation groove 11 is arranged on the body 1, a buffer area 2 is arranged below the installation groove 11, a turnover connecting strip 3 is connected to the buffer area 2, and a scraping strip 4 is connected below the turnover connecting strip 3.

[0003] The turnover connecting strip 3 is used for turning the scraping strip 4, for example, when the wiper needs to be turned from one side to the other side, the turnover connecting strip 3 is reversely bent to make the scraping strip adhere to the glass in the advancing direction of the wiper. Since the wiper is always moving back and forth, the scraping strip needs to be repeatedly turned, and therefore the turnover connecting strip cannot be too thick, otherwise it cannot be smoothly turned, which causes the turnover connecting strip to be easily damaged in the process of repeated turning, and affects the service life of the product.

[0004] In addition, the rubber strip is solid, and completely relies on the elasticity of the material itself to adhere to the glass, which causes the scraping strip to be not easy to adhere to the glass, and causes the scraping to be not clean. SUMMARY

[0005] The present application aims to provide a hollow wiper rubber strip, which greatly improves the service life of the product.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a hollow wiper rubber strip, comprising a body, an installation groove is arranged on the body, a buffer area is arranged below the installation groove, an enlarged portion is arranged below the buffer area, a scraping strip is arranged below the enlarged portion, and a cavity is further arranged, which penetrates through the enlarged portion and the scraping strip. After the cavity is added, the deformation ability of the rubber strip is enhanced, and therefore a thicker enlarged portion can be used to replace the original turnover connecting strip, and the service life is greatly increased. In addition, when the wiper is pressed, the cavity can also be deformed to a certain extent, which can make the wiper adhere to the glass more tightly, and make the scraping more clean.

[0007] As a preferred embodiment of the present application, the lower end of the enlarged portion has protrusions extending on both sides, which are in contact with the outer wall of the enlarged portion when the wiper slides left and right, and limit the turning range of the scraping strip.

[0008] As a preferred embodiment of the present application, the cross section of the scraping strip is rectangular.

[0009] Compared with the prior art, the present application has the following advantages:

[0010] The deformation ability of the rubber strip is enhanced after the cavity is added, so a thicker bulging part can be used to replace the original flip connecting strip, and the service life is greatly increased. In addition, when the wiper is pressed, the cavity can also deform to a certain extent, so that the wiper is more closely attached to the glass, and the wiping is cleaner.

[0013] To make the technical means, creative features, purposes and effects of the present application easy to understand, the present application will be further described below in conjunction with specific embodiments.

[0014] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0015] Please refer to Figure 2 The present application provides a technical solution: a hollow wiper rubber strip, comprising a body 1, the body 1 is provided with a mounting groove 11, the lower side of the mounting groove 11 is provided with a buffer area 2, the lower side of the buffer area 2 is provided with a bulging part 5, the lower side of the bulging part 5 is provided with a scraping strip 4, and further comprising a cavity 1a, the cavity 1a penetrates through the bulging part 5 and the scraping strip 4.

[0016] The lower end of the bulging part 5 has protrusions 51 extending on both sides, which contact the outer wall of the bulging part when the wiper slides left and right, limiting the rotation range of the scraping strip.

[0017] The cross section of the scraping strip 4 is rectangular.

[0018] The deformation ability of the rubber strip is enhanced after the cavity is added, so a thicker bulging part can be used to replace the original flip connecting strip, and the service life is greatly increased. In addition, when the wiper is pressed, the cavity can also deform to a certain extent, so that the wiper is more closely attached to the glass, and the wiping is cleaner.

Claims
