Background technology

Traditional a part of suspension hook has only an arc shaped hook, and structure is too simple, and in the process of weight of slinging, safety performance is not so good, all has the danger that comes off at any time; Some suspension hook has self-locking mechanism, although solved safe problem, this suspension hook complex structure, manufacturing cost height, uses also very inconveniently, when hanging the spy or unloading thing, needs by manually opening it, and it is very inconvenient to operate.

Summary of the invention

The purpose of this utility model provides a kind of jaw type electromagnetism hook esy to use, safe and reliable, robust.

For achieving the above object, the technical scheme that the utility model adopted is:

A kind of jaw type electromagnetism hook, it is characterized in that: it is by carrier base, hook A, hook B, rocking arm A; rocking arm B, magnetic core pull bar and magnet coil constitute; described magnet coil is located on the carrier base; an end of magnetic core pull bar is located in the magnet coil; the other end is simultaneously hinged with the end of rocking arm A and rocking arm B by round pin, and the other end of rocking arm A and rocking arm B is hinged with hook A and hook B respectively, and hook A and hook B are hinged on the carrier base by hinge; Described magnetic core pull bar is provided with retracing spring.

Described carrier base is to be made of suspension ring, support body and adapter plate, and suspension ring are located at the top of support body, and adapter plate is located at the both sides of support body bottom, is respectively equipped with hinge hole on two adapter plates, and the two ends of hinge are located in the hinge hole.

Be respectively equipped with corresponding pilot hole on described two adapter plates, the two ends of described round pin are located in the pilot hole.

Described magnet coil is fixed on the bottom panel of support body by screw.

The central part of the bottom panel of described support body is provided with through hole, and described magnetic core pull bar passes from through hole.

The bottom of described magnetic core pull bar is provided with the annular cover, and an end roof pressure of retracing spring puts in annular, and other end roof pressure is on the bottom surface of support body.

The utility model beneficial effect: owing to adopt the form of jaw type electromagnetism hook, make the loop wheel machine of boats and ships dispensing device in the ocean drive the rapid releasing arrangement of electromagnetism hook by instruction, equipment is promptly and accurately thrown in, reduce the accident generation that influences the easy clashing and breaking of forming device because of stormy waves greatly, reduced because of the artificial operation of slowly breaking off relations and missed best input opportunity, equipment can not have been satisfied throw in the negative effect that requires and cause.The more important thing is: adopt mechanical dispensing device to avoid the security risk of artificial input.Jaw type electromagnetism hook has overcome the not enough of common loop wheel machine hitcher existence and has researched and developed according to the operating needs specific aim.The utility model also has simple in structure, sturdy and durable, safe and reliable characteristics.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is the utility model structural representation;

Fig. 2 is an assembly drowing shown in Figure 1.

Among the figure: 1, carrier base; 2, hook A; 3, hook B; 4, rocking arm A; 5, rocking arm B; 6, magnetic core pull bar; 7, magnet coil; 8, round pin; 9, hinge; 10, retracing spring; 11, suspension ring; 12, support body; 13, adapter plate; 14, hinge hole; 15, pilot hole; 16, screw; 17, the bottom panel of support body; 18, through hole; 19, annular cover.

The specific embodiment

As Fig. 1, shown in 2, a kind of jaw type electromagnetism hook, it is by carrier base 1, hook A2, hook B3; rocking arm A4; rocking arm B5; magnetic core pull bar 6 and magnet coil 7 constitute; described carrier base 1 is by suspension ring 11; support body 12 and adapter plate 13 constitute; suspension ring 11 are located at the top of support body 12; adapter plate 13 is located at the both sides of support body 12 bottoms; be respectively equipped with hinge hole 14 on two adapter plates 13; two ends of hinge 9 are located in the hinge hole 14, are respectively equipped with corresponding pilot hole 15 on described two adapter plates 13, and the two ends of described round pin 8 are located in the pilot hole 15; central part of the bottom panel 17 of described support body is provided with through hole 18, and described magnetic core pull bar 6 passes from through hole 18; Described magnet coil 7 is fixed on the bottom panel 17 of support body by screw 16, one end of magnetic core pull bar 6 is located in the magnet coil 7, the other end is simultaneously hinged with the end of rocking arm A4 and rocking arm B5 by round pin 8; other end of rocking arm A4 and rocking arm B5 is hinged with hook A2 and hook B3 respectively, and hook A2 and hook B3 are hinged on the carrier base 1 by hinge 9; The bottom of described magnetic core pull bar 6 is provided with annular cover 19, and an end roof pressure of retracing spring 10 is on annular cover 19, and other end roof pressure is on the bottom panel 17 of support body.

Principle of work: hook A, hook B, rocking arm A, rocking arm B forms a jaw type hook, and under the cold situation of magnet coil, two hooks in the jaw type hook are in the state of closed self-locking under the effect of retracing spring; When magnet coil was switched on, the magnetic that magnet coil produced was inhaled mutually with the magnetic of magnetic core pull bar, under the effect of magnetic force, moved on the magnetic core pull bar, thereby drove rocking arm A and rocking arm B, and two hooks are opened, and this moment, retracing spring was in compressive state.
