Abstract

The utility model relates to a steel cable knot fastening device, particularly a late-model self-tightening steel cable knot fastening device which is characterized in that two tapered plug holes which are arranged on an outer sleeve along the opposite direction are matched with tapered inner sleeves which form two pieces and are arranged in a separated mode in a tightening mode, and the two tapered plug holes are connected with the tapered inner sleeve in a movable mode. The inner wall of the inner sleeve is provided with a pattern which is inosculated with the spiral twist of a steel cable. The utility model has the advantages of small volume, light weight, simple structure, convenient installation and time saving. A rope sleeve can be installed in a plurality of minutes. The work efficiency is enhanced. The utility model can be widely used for various cable cars, hoists and various crane slings in factories and mines.

Description

A kind of novel self tightening steel wire loop fastener

The utility model relates to a kind of steel wire loop fastener, particularly a kind of novel self tightening steel wire loop fastener.

Now, the unit in charge of construction steel wire loop termination of using is generally to compile and inserts or mode such as U shaped steel silk wire clips fixedly forms.The manual volume of employing is inserted and is reached fixedly steel wire loop of the slotting rope machine of various types of steel wires, and labor intensity is big, and inefficiency also easily causes industrial injury; Adopt fixedly steel wire loop of U shaped steel silk wire clips, area of contact is little, and tightness is poor, and the easy slippage of rope sling is dangerous.

The utility model purpose is can overcome the prior art deficiency for unit in charge of construction provides a kind of, and effectively steel wire loop is fixed together, and prevents the novel self tightening steel wire loop fastener of wire rope slippage.

The utility model is achieved in that below in conjunction with drawings and Examples does detailed description to the utility model.

Fig. 1 is an overall structure schematic representation of the present utility model.

Fig. 2 is an A-A ' sectional drawing of the present utility model.

Fig. 3 is the utility model overcoat longitudinal sectional drawing.

Fig. 4 is a cover longitudinal sectional drawing in the utility model.

As shown in the figure, overcoat (3) is gone up two conical socket (7,8) of being provided with in the other direction and is two bulks and separates in the taper of setting cover (4) and be that drive fit is movable to be connected, in the inwall of cover (4) be provided with the decorative pattern that matches with wire rope (5) spiral fried dough twist, gland (1) is drive fit work by the screw rod (6) that fixedly installs on the overcoat (3) and nut (2) with overcoat (3) respectively and is connected.

When the utility model is installed, steel wire rope head is inserted from the conicle cross section of conical socket (7,8) end, as shown in Figure 1, promptly wire rope is inserted in the left side from jack (7) to jack (8) and forms the rope sling ring.Gland (1) with two ends is first-class then, prevents interior cover (4) and wire rope (5) slippage voluntarily.So far the utility model just install, stressed as steel wire loop, then wire rope (5) is together with interior cover (4) most advanced and sophisticated slippage to taper in jack (7,8), interior cover (4) is just tighter with the wire rope extruding, rope sling is also just firm.

The utility model can be made into the product of the different size that adapts to the above wire rope of Φ 10mm, its advantage be volume little, in light weight, simple in structure, be suitable for manufacturing, easy for installation, only need a few minutes what a rope sling can be installed, save time, increase work efficiency.The utility model can be widely used in various cable cars, lift and the various hoisting slings etc. in factory, mine.
