Abstract

本实用新型属日用五金类,具体地说是一种木螺 钉。本实用新型的要点是:在木螺钉尖端部开始向上 占螺钉总长1/4~2.5处为无丝光杆(1),光杆的外 形为圆锥形或多棱锥形或多棱锥形。本木螺钉有易 定位、易旋进阻力小等优点。

Description

本实用新型属日用五金类,具体地说是一种木螺钉。
通常人们使用的木螺钉的螺纹,从尖端部开始向上是全丝或半丝状,使用时因尖端部位有丝,导致难定位,旋进时易歪斜,阻力大。
本实用新型的目的是制造一种使用方便,易定位,旋进省力的尖端部位无丝木螺钉。
本实用新型是这样实现的,由木螺钉的尖端部开始向上占木螺钉总长度的1/4-1/2.5处是无丝的光杆。该光杆的外形是圆锥形或多棱锥形,其锥度为螺钉丝底锥度的延长。
由于本木螺钉的尖端部为圆锥形或多棱锥形光杆,在使用本木螺钉时。木螺钉前端尖部首先起定心引导作用。同时具有旋进或击打时阻力小的特点,并可使旋进速度加快三分之一。
图1是本实用新型的结构原理图。
实施例:尖端部无丝木螺钉的主要部分是从尖端开始向上占体部长1/4~1/2.5处为无丝光杆(1)。光杆(1)的外形是圆锥形或多棱锥形。光杆(1)的锥度即螺钉丝底锥度的延长。

Claims (2)

1、一种尖端部无丝木螺钉,其特征是:由木螺钉尖端部开始向上占螺钉总长1/4~1/2.5处是无丝光杆(1)。
2、根据权利要求1所述的一种尖端部无丝木螺钉,其特征在于:所说的无丝光杆(1)的外形为圆锥形或棱锥形。
