Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] Such as figure 1 As shown, the new nut includes a nut body 1, the center of the nut body is provided with a threaded hole 2, and the end surface of one side of the nut body is provided with a protective sleeve, and the protective sleeve includes a ring-shaped rubber sleeve 3. The annular rubber sleeve is concentric with the threaded hole, and is fixedly connected with the end face of the nut body, and also includes a hemispherical rubber cover 4, and the flat end of the hemispherical rubber cover is provided with the same diameter as the threaded hole. The circular groove, the hemispherical rubber cover and the annular rubber sleeve form a closeable connection.

[0012] The outer periphery of the plane end of the hemispherical rubber cover is fixedly connected with the surface of the annular rubber sleeve. This structure real...

Abstract

The invention relates to the field of tool accessories, and in particular discloses a novel screw cap which comprises a screw cap body as well as a semispherical rubber cover, wherein a threaded hole is formed in the center of the screw cap body; a protecting sleeve is arranged on the end surface of one side of the screw cap body; the protecting sleeve comprises an annular rubber sleeve; the annular rubber sleeve shares the center with the threaded hole and is fixedly connected with the end surface of the screw cap body; a circular groove of which the diameter is identical to that of the threaded hole is formed in a planar end of the semispherical rubber cover; the semispherical rubber cover and the annular rubber sleeve are in closable connection with each other. The novel screw cap provided by the invention is relatively good in water resistance and long in service life compared with a conventional screw cap.

Description

technical field [0001] The invention relates to the field of tool accessories, in particular pointing out a novel nut. Background technique [0002] Most of the traditional nuts are directly provided with screw holes in the center of the nut body. During use, the nuts are prone to rust and corrosion directly with the screw rod, making it difficult to disassemble. Contents of the invention [0003] The purpose of the present invention is to provide a new type of nut, which has better waterproof performance and prolongs the service life than the traditional nut. [0004] The technical scheme that realizes the object of the present invention is as follows: [0005] The novel nut includes a nut body, the center of the nut body is provided with a threaded hole, and it is characterized in that a protective sleeve is provided on one side of the nut body, and the protective sleeve includes a ring-shaped rubber sleeve. The annular rubber sleeve is concentric with the threaded hol...
