Abstract

The utility model relates to a isodiametric hook and an isodiametric ring. The utility model is provided with a isodiametric hook, and the radius of a semicircular ring of the isodiametric hook is equal to the pipe diameter of the isodiametric hook. The utility model is also provided with a isodiametric ring, the radius of the isodiametric ring is equal to the pipe diameter of the isodiametric ring, and the radius of the semicircular ring of the isodiametric hook is equal to the radius of the isodiametric ring. A connecting handle is arranged on the isodiametric ring. When the utility model is applied, the isodiametric hooks are fixedly arranged on the front and the back automobile frames of every vehicle, and the isodiametric rings are put in the vehicles for standby use. When the vehicles needs dragging, the isodiametric rings and the connecting handles are taken out of the vehicles, and the isodiametric rings are respectively sheathed in the isodiametric hooks of the front and the back vehicle frames, and every two connecting handles are connected for realizing the operation that the vehicles are dragged. Through the utility model, the vehicles are stably dragged and are hard crashed. The utility model has the advantages of simple, convenient, and quick connection, good use effect, safety, etc.

Description

Isometrical hook and isometrical ring

The utility model relates to mechanical component, is a kind of instrument that is used for trailer.

Existing automobile is equipped with car puller hook mostly on the vehicle frame of front and back, in order to dilatory mutually assistance when casting anchor, this car puller hook uses wirerope to connect usually.Also have a kind of trailer that is exclusively used in relief, design has a leg-of-mutton towing carriage, is provided with a ring above, and ring set is gone into by the hook of trailer, realizes connecting and trailer, and this hook and ring do not have strict size to cooperate, and it is unstable to drag cycling start, and often bumps.

The purpose of this utility model is a kind of general-duty Trailer tool of design, use this instrument can realize easily with by being connected of trailer, stablize during trailer, do not bump.

The utility model is realized by following approach.

Design a kind of isometrical hook, the semicircular ring radius of this isometrical hook equates with its caliber, design a kind of isometrical ring again, the radius of this isometrical ring equates that with its caliber the semicircular ring radius of isometrical hook equates on the isometrical ring connection handle is arranged with the radius of isometrical ring, during manufacturing, the caliber of isometrical hook is slightly less than the radius of its semicircular ring, and smaller its radius of the caliber of isometrical ring can be inserted in the isometrical hook isometrical ring.

During application, isometrical hook is fixedly mounted on the forward and backward vehicle frame of automobile, isometrical ring is then put standby onboard, when the needs trailer, take out isometrical ring and connection handle from each car, isometrical ring is inserted in respectively in the isometrical hook of forward and backward car, again two connection handles are coupled together, start front truck, realize the trailer operation.

The utility model has used isometrical ring and isometrical hook in the connection of trailer, cooperate precision, drags cycling start to stablize, and is difficult for bumping, and has advantages such as connection is simple and efficient, result of use good, safe and reliable.

Example with accompanying drawing is further described the utility model below:

Accompanying drawing is a structural representation of the present utility model.

This example has isometrical hook 1, the neck of hook 4, isometrical ring 2, connection handle 3 to constitute, isometrical hook 1 is formed by connecting by the semicircular ring and the neck of hook 4, isometrical ring 2 is connecting connection handle 3, the semicircular ring radius r 1 of isometrical hook 1 equates with its caliber t1, the radius r 2 of isometrical ring 2 equates with its caliber t2, the semicircular ring radius r 1 of isometrical hook 1 equates with the radius r 2 of isometrical ring 2, during manufacturing, make the caliber t1 of isometrical hook 1 be slightly less than its semicircular ring radius r 1, smaller its radius r 2 of the caliber t2 of isometrical ring 2 can be inserted in the isometrical hook 1 isometrical ring 2.

During application, the neck of hook 4 of isometrical hook 1 is fixedly mounted on the forward and backward vehicle frame of automobile, 2 on isometrical ring is put standby onboard, when the needs trailer, take out isometrical ring 2 and connection handle 3 from each car, isometrical ring 2 is inserted in respectively in the isometrical hook 1 of forward and backward car, again two connection handles, 3 usefulness connected nails 5 are coupled together, start front truck, realize the trailer operation.
