Abstract

The invention relates to a metal knotter comprising a metal rope and a heating lance. The heating lance comprises a handle, an on-off switch and a heating passage. The heating passage is a tubular chamber. Heating coils coaxial with the heating passage are densely distributed in the wall of the tubular chamber at equal intervals. The heating coils are coupled the on-off switch arranged on the outer wall of the handle. The on-off switch is coupled to an alternating current source arranged inside the handle. The metal rope is made of two-way memory alloy good in thermal conductivity. At normal temperature, the metal rope is bent into a knot; at high temperature, the metal rope is extended into a straight rod. A metal ring is fixed to the tail end of a cable matching with the metal knotter. The metal knotter allows automatic knotting and is simple to operate; time for emergencies is greatly saved; the cable can be firmly tied with the metal knotter.

Description

A kind of metal knotter

Technical field

The present invention relates to a kind of metal articles for use, especially, is a kind of knotting device.

Background technology

When carrying out operation at sea, often run into emergency situation, as needed to do emergency treatment to hull before storm arrives; At this moment usually need fastening for hawser knotting, this knot will ensure firmly, and knotting method is uncomplicated simultaneously; But, when new hand operates, the more time may be spent, even tie a knot firm not, can potential safety hazard be left.

Summary of the invention

For the problems referred to above, the invention provides a kind of metal knotter, this metal knotter can realize automatic knotting, simple to operate, in case of emergency saves the plenty of time, and hawser firmly can be bound.

For solving the problem, the technical solution adopted in the present invention is: this metal knotter includes metallic cable and heating gun; Described heating gun includes handle, on and off switch and heating road; Described heating road is cylindrical cavity, is equidistantly densely covered with the heater coil coaxial with this heating road in its barrel; Described heater coil is coupled to the described on and off switch being positioned at handle outer wall; Described on and off switch is coupled to the source of AC being positioned at handle inner; Described metallic cable is made by the two-way memory alloy of good permeability of heat, and the normal temperature of this metallic cable is bent to knotting state mutually, and high-temperature-phase is stretched to a straight-bar; The end of the hawser matched with this metal knotter is fixed with becket.

The invention has the beneficial effects as follows: when needs are tied a knot, described heating road is inserted in one end of metallic cable, regulate described on and off switch connection circuit, exchange current arrives heater coil through described on and off switch, according to electromagnetic induction eddy current principle of heating, as long as the heating one end of the described metallic cable of periodically variable exchange current is to high temperature phase morphology, again due to the heat transfer of metallic cable, metallic cable is stretched to a straight-bar gradually; By the described metallic cable in straight-bar successively through the described becket on two hawsers, regulate described on and off switch cut off, under the combined action of sea wind and seawater, described metallic cable down quench, return back to normal temperature phase morphology, and described becket is firmly bound together; When needs take off, use heating gun to heat described metallic cable, making it return to high-temperature-phase form can easily take off.

Utilize the special construction of memorial alloy, what this metal knotter can be quick and easy firmly binds hawser, provides very large help, solve time during emergency situation to new hand, effectively ensures ship and personal safety; This metallic cable is made into standard knotting shape when producing simultaneously, and metal knot when ensureing each use is all firm, improves safety factor further; This memorial alloy can realize ten million time repeating, and has the very long life.

As preferably, a temp-controlling element of connecting between described on and off switch and described heater coil; Regulate stream as the electric current of heater coil by the resistance changed in circuit, thus control the temperature of heater coil; Thus make heating gun be applicable to the metallic cable of different deformation temperature.

As preferably, be enclosed with thermal insulation layer at the periphery wall in described heating road; So that the heat of heater coil is kept in heating road cavity, effectively prevent from scalding simultaneously.

Detailed description of the invention:

Embodiment

In the embodiment shown in Fig. 1, Fig. 2, this metal knotter includes metallic cable 4 and heating gun 1; Described heating gun 1 includes handle 3, on and off switch 32 and heating road 2; Described heating road 2 is cylindrical cavity, is equidistantly densely covered with the heater coil 21 coaxial with this heating road 2 in its barrel; Thermal insulation layer (not shown) is enclosed with at the periphery wall in described heating road 2; Described heater coil 21 is coupled to the described on and off switch 32 being positioned at handle 3 outer wall; Described on and off switch 32 is coupled to the source of AC 31 being positioned at handle 3 inside; A series connection temp-controlling element 33 between described on and off switch 32 and described heater coil 21; Described metallic cable 4 is made by the two-way memory alloy of good permeability of heat, and the normal temperature of this metallic cable 4 is bent to knotting state mutually, and high-temperature-phase is stretched to a straight-bar; The end of the hawser 5 matched with this metal knotter is fixed with becket 51.

When needs are tied a knot, described heating road 2 is inserted in one end of metallic cable 4, open described on and off switch 32 connection circuit, regulate described temp-controlling element 33, resistance in overregulate temp-controlling element 33, change the electric current flowed in heater coil 21, it is made to arrive suitable temperature, exchange current flows to heater coil 21, according to electromagnetic induction eddy current principle of heating, as long as the heating one end of the described metallic cable 4 of periodically variable exchange current is to high temperature phase morphology, again due to the heat transfer of metallic cable 4, now metallic cable 4 is stretched to a straight-bar gradually; By the described metallic cable 4 in straight-bar successively through the described becket 51 on two hawsers 5, regulate described on and off switch 32 cut off, under the combined action of sea wind and seawater, described metallic cable 4 down quench, return back to normal temperature phase morphology, and described becket 51 is firmly bound together; When needs take off, use heating gun 1 to heat described metallic cable 4, making it return to high-temperature-phase form can easily take off; Heat is isolated in heating road cavity by the described thermal insulation layer being positioned at described heating road 2 periphery wall, increases work efficiency, prevents unexpected scald simultaneously.

Utilize the special construction of memorial alloy, what this metal knotter can be quick and easy firmly binds hawser 5, provides very large help, solve time during emergency situation to new hand, effectively ensures ship and personal safety; This metallic cable 4 is made into standard knotting shape when producing simultaneously, and metal knot when ensureing each use is all firm, improves safety factor further; This memorial alloy can realize ten million time repeating, and has the very long life.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
