Description

The two-sided hook of sea rescue

Technical field

The two-sided hook that the utility model uses when relating to a kind of sea rescue person's lifesaving.

Background technology

At present, owing to be subjected to the influence of objective factor or subjective factor, casualty is unavoidable, in case casualty takes place then rescue with all strength, to reduce personal casualty to greatest extent.With the sea rescue is example, method commonly used is to use air inflation raft and canoe or sampan to carry out sea rescue, also have and adopt autogyro to carry out lifesaving, but air inflation raft and canoe or sampan one are to read use to plunge into the commercial sea in level Four, the 2nd, canoe or sampan also can break down or break off relations in the process of hanging, and gently then canoe or sampan fail to lay down receipts and do not go up, and be heavy then cause man overboard or injures and deaths.If the direct entry of employing lifeguard is sued and laboured then can be overcome the problems referred to above, and can improve lifesaving efficient, save the lifesaving time, the direct entry rescue of lifeguard then must at first guarantee lifeguard's safety, must keep and the getting in touch of lifesaving naval vessels by life line and relevant device thereof after lifeguard's entry, can guarantee lifeguard's flexible motion, can guarantee in time the lifeguard again or be rescued personnel to be promoted on the naval vessels deck by life line.When the lifeguard touches when being rescued personnel, must at first be put life belt to rescuing personnel, and then life belt linked to each other with the life line that the lifeguard brings, existing method of attachment generally adopts the method for knotting that life belt is linked to each other with life line, this method is dangerous on the one hand, because marine stormy waves is bigger, knotting is difficulty relatively on the other hand, influences the effect of suing and labouring.

Summary of the invention

The purpose of this utility model provide a kind of connect life line and life belt the two-sided hook of sea rescue.

The technical solution of the utility model is:

The two-sided hook of a kind of sea rescue, an end that it is characterized in that main cover 1 is provided with mounting hole 12, jam nut 3 is spirally connected with mounting hole 12, and the lower end of hanging bolt 2 is passed jam nut 3 and linked to each other with coupler body 5, and the upper end of hanging bolt 2 is arranged in mounting hole 12 and nut 9 is installed; Bearing 10 is installed between nut 9 and the jam nut 3, and is sleeved on the hanging bolt 2; Be connected with a main hook 13 and at least one auxiliary hook 14 on the coupler body 5.

The other end of main cover of the present utility model also is provided with a life line perforation 15, and life line is set in the life line perforation 15, and links to each other with relevant device on the lifesaving naval vessels.On the outer wall of jam nut 3 and mounting hole 12 locating dowel pin 4 is installed, the effect of locating dowel pin 4 is to prevent the rotation of jam nut and move up and down.At the mouth of hook place of main hook 13 and auxiliary hook 14 main hook deck 7 and auxiliary hook deck 8 are installed respectively; Main hook deck 7 and auxiliary hook deck 8 are installed on wearing in the pin 11 separately respectively, wearing pin 11 is installed on the coupler body 5, torsion spring 6 is installed in wearing pin 11, make main hook deck 7 and auxiliary hook deck 8 produce the torsion of a side direction in the mouth of hook all the time, prevent that main hook deck 7 and auxiliary hook deck 8 from rotating to the mouth of hook outside, so that life belt is clamped in the mouth of hook all the time, guarantee the success of lifesaving.A via hole 16 also can be set on auxiliary hook 14 or main hook 13.

The beneficial effects of the utility model:

1, solves the lifeguard in the process of suing and labouring, rescued and seek and the quick bonded assembly difficult problem of life belt, both improved connection speed, guaranteed the bonded assembly reliability again, shortened the lifesaving time, alleviated lifeguard's labour intensity, improved entry lifesaving seakeeping.

2, simple in structure, in light weight, easy to carry, easy to connect in the process of suing and labouring, quick.

3, two-sided hook two people that can sue and labour have simultaneously improved the efficient of suing and labouring.

4, both can be used for sea rescue, used when also can be used for rivers, lake lifesaving.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1, the two-sided hook of a kind of sea rescue, comprise main cover 1, hanging bolt 2, jam nut 3, bearing 10, coupler body 5, one end of main cover 1 is provided with mounting hole 12, and jam nut 3 is spirally connected with mounting hole 12, and the lower end of hanging bolt 2 is passed jam nut 3 and coupler body 5 and linked to each other by screw thread, should adopt checknut herein, but the person screws the back at screw thread adopts the method for welding to make hanging bolt 2 and coupler body 5 affixed, prevents that coupler body 5 separates with main cover 1 in the use, produces serious safety misadventure.The upper end of hanging bolt 2 is arranged in mounting hole 12 and nut 9 is installed; Bearing 10 is installed between nut 9 and the jam nut 3, and is sleeved on the hanging bolt 2, guarantees that coupler body 5 can be with hanging bolt 2 revolutions; Be welded with a main hook 13 and at least one auxiliary hook 14 on the coupler body 5.In order to prevent that seawater or impurity from entering in the mounting hole 12 bearing 10 is produced corrosion, present embodiment is pressed with seal ring 17 in the bottom of jam nut 3, the inner wall sealing of the outer ring of seal ring 17 and mounting hole 12, and seal mutually with the hanging bolt 2 that passes wherein.

The other end of main cover 1 of the present utility model also is provided with a life line perforation 15, and life line is set in the life line perforation 15, and with the lifesaving naval vessels on relevant device, link to each other as the lifesaving suspension rod.Be coated with locating dowel pin 4 on the outer wall of jam nut 3 and mounting hole 12, the effect of locating dowel pin 4 is to prevent the rotation of jam nut and move up and down, and prevents that jam nut 3 breaks away from main cover 1, thereby makes hanging bolt 2 break away from main cover 1, produces the unhook accident.At the mouth of hook place of main hook 13 and auxiliary hook 14 main hook deck 7 and auxiliary hook deck 8 are installed respectively; Main hook deck 7 and auxiliary hook deck 8 are installed on wearing in the pin 11 separately respectively, wear pin 11 solid shapes on coupler body 5, torsion spring 6 is installed in wearing pin 11, make main hook deck 7 and auxiliary hook deck 8 produce the torsion of a side direction in the mouth of hook all the time, prevent that main hook deck 7 and auxiliary hook deck 8 from rotating to the mouth of hook outside, so that life belt is clamped in the mouth of hook all the time, guarantee the success of lifesaving.A via hole 16 also can be set on auxiliary hook 14 or main hook 13.In via hole 16, can wear an auxiliary lifesaving trailing cable, use for the lifeguard.

Material of the present utility model should adopt the manufacturing of resistant to corrosion stainless steel material.

During lifesaving, by the lifeguard life belt of self is inserted in the main hook of lifesaving of the present utility model with two-sided hook, be with life line and life belt together near being rescued personnel then, when touching when being rescued personnel, at first put on life belt, depress the auxiliary hook deck on the two-sided hook then, life belt is put into auxiliary hook for rescuing personnel, under the drive of life line, return the naval vessels of suing and labouring then together, hang on the deck.If the lifeguard also will continue to succour other persons falling in water, then can before lifting, lifeguard's life belt on one's body be taken out from main hook, the lifeguard links to each other with main life line by the auxiliary life line of via hole, after being rescued personnel and being hung on the deck, life belt and the disengaging of two-sided hook can be put down two-sided hook once more by the operating personal on the deck, after the lifeguard catches two-sided hook, the life belt of self is inserted in main hook once more, and trip is rescued personnel to another, carries out the aforementioned identical work of suing and labouring.
