Abstract

A strainer, consisting of a thimble (1), a hamate (2) and a draw hook (3), is characterized in that the thimble (1) is a quoit; the thimble (1) and the hamate (2) form an U-shaped, which is convenient for a double rope to pass the thimble to fasten the strainer firmly; a pulley (3-1) is covered on the draw hook (3) to make a draw rope bundle the goods with a very little friction force.

Description

Strainer

Technical field

The utility model relates to a kind of strainer.

Background technology

During with rope (or strap) bale cargo, for goods is bound, someone is knotted into a circle to rope, then rope is passed the circle that rope forms and pull at, goods is bound, this circle that is knotted into rope is exactly comparatively original strainer, wire rope handling from this Artenkreis and straining, friction force between rope and rope is big, effort, and rope is ruptured because of friction.

Summary of the invention

In order to overcome the deficiency of above technology, the purpose of this utility model provides and produces the very little strainer of friction force when rope bundle goods draws.

Embodiment of the present utility model is: the utility model product is made up of bundle ring, hamate bone, drag hook three parts.With the diameter is the reinforcing bar of 0.4-1.2cm or the bundle ring that plastics are material, hamate bone, drag hook is one integrated mass from top to bottom successively, pricking ring (1) is that diameter is 2-6cm reinforcing bar circle or tetragonal circle ring, the reinforcing bar that encloses into bundle ring (1) extends, behind crooked about 180 degree, the reinforcing bar of straight elevator is about 4-10cm downwards, the part of this straight elevator is called hamate bone (2), the reinforcing bar K/UP of hamate bone (2) bottom becomes " U " type, be referred to as drag hook (3), be with pulley (3-1) on the drag hook (3), it is characterized in that: pricking ring (1) is a circle ring, prick between ring (1) and the hamate bone (2) and become " U " type, be convenient to dual rope and overlapped and prick ring and tie down strainer securely, be with pulley (3-1) on the drag hook (3), friction force is minimum when making it to draw the location with rope bundle goods.

The beneficial effects of the utility model are: prick between ring and the hamate bone and becomes " U " type, be convenient to dual rope and overlap bundle and encircle and tie down strainer securely, never drop-off, the pulley on the drag hook make when straining rope friction force minimum.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure, the 1st, prick ring, the 2nd, hamate bone, the 3rd, drag hook, 3-1 are pulleys.

The specific embodiment

As shown in the figure, during with rope (or strap) bale cargo, with dual rope penetrate prick ring after, the bundle ring was overlapped in the dual partial switching of rope, rope is pricked in " U " type knee of pricking between ring and the hamate bone, and rope just fastens firmly to prick and encircles like this, and the other end that bundle is surrounded the goods rope rides on the pulley of drag hook again, pull rope, pulley slides, and rope shortens, and tightly ties goods, therefore use this strainer bale cargo be laborsaving to save time, simple and feasible.

Claims (1)

1, a kind of strainer, form by bundle ring (1), hamate bone (2), drag hook (3) three parts, it is characterized in that: pricking ring (1) is a circle ring, prick between ring (1) and the hamate bone (2) and become " U " type, being convenient to dual rope overlapped the bundle ring and tied down strainer securely, be with pulley (3-1) on the drag hook (3), friction force is minimum when making it to draw the location with tow bundle goods.
