Abstract
The invention provides a safe D-type buckle with a sheath which belongs to lifting industry, which aims at solving the shortcoming of the D-shaped buckle used in the current lifting industry that safety accidents easily occur during lifting operation course due to unfixed location of a steel rope in the D-type buckle; the characteristics of the invention are as follows: a U-shaped ring is provided with a bolt rod; the bolt rod is provided with a center sheath, therefore, the steel rope can be ensured to be always in center location of the center sheath, not only the steel rope can not move, but also the force is always applied in the center location of the center sheath, and the invention is safe and reliable.
Description
Technical field:
The invention belongs to a kind of safe D-type buckle that the lifting industry is used with sheath.
Background technique:
The employed D type of present lifting operation is buckled, and ubiquity because the position of wire rope in the D type is buckled is fixing, and the very little stress of wire rope bending radius is concentrated, is easy to take place security incident in the process of lifting operation.
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned shortcoming, and a kind of safe D-type buckle with sheath that provides.
The present invention is achieved in that a kind of safe D-type buckle with sheath is made up of bolt shank, central sheath, U type ring and wire rope, it is characterized in that: on U type ring bolt shank is installed, central sheath is installed on bolt shank.
The present invention is owing to be equipped with central sheath on bolt shank, so it can guarantee that wire rope is in the central position of central sheath all the time, not only wire rope can not move, and firmly is in the central position of central sheath all the time, and is safe and reliable.
Description of drawings:
Fig. 1 is a plan view of the present invention.
Fig. 2 is the left view of Fig. 1.
Each label declaration is as follows among the figure:
1, by bolt shank, 2, central sheath, 3, U type ring, 4, wire rope.
Embodiment:
Now describe embodiments of the invention in conjunction with the accompanying drawings in detail.
The present invention is reliable for working stability, bolt shank 1, central sheath 2 and U type ring 3 all adopt the 45# steel processing of high-quality to manufacture, must heat-treat after machining is intact, the effect of bolt shank 1 is a carrying central sheath 2, and the effect of central sheath 2 is to guarantee that wire rope 4 is in the position at center all the time.
In sum, the present invention is easy to use steadily, and is safe and reliable.
