Abstract
The utility model provides a kind of longeron car puller hook, comprise and be bent into U-shaped towing hook portion, interconnecting gangway and fixed base by round steel, the right side in the towing hook portion of semicircular arc is fixedly connected with two parallel interconnecting gangways, fixed base is fixedly connected on the right side of interconnecting gangway in obtuse angle, distance between two parallel fixed base is two times of the diameter of fixed base, and the right-hand member of fixed base is provided with the connector be connected with the longeron of automobile.The beneficial effects of the utility model are mounted on the longeron of automobile, and the vehicle frame of automobile can not be pulled distortion, and itself can not be out of shape fracture easily, structure is simple, easy to use firm.
Description
Technical field
The utility model belongs to hitch field, especially relates to a kind of longeron car puller hook.
Background technology
The car puller hook of the front lower portion and rear lower that are arranged on automobile is a kind of draw gear, when vehicle failure for drawing disabled vehicle or being used by during trailer traction; Existing car puller hook is mostly the circular parallel structure being fixedly connected on single fixed base of towing hook, during use, fixed base is fixedly connected with automobile, the towing hook of ring-type is for carrying out the contact point pulled, and now the transversal surface of the towing hook of ring-type is generally circular, when horizontal direction pulls, the stress point of hook portion is uneven, easy generation stress and deformation, and then bending fracture, cause safety misadventure; On the other hand, single fixed base can regard the cantilever beam bearing horizontal drag drag as, the flexure stress that this position is born is maximum, stress can be aggravated further with the structure design of towing hook parallel docking to concentrate, transitional structure and corresponding curved design is helped if do not exist, as easy as rolling off a log generation deformation and fracture, have a strong impact on the safe reliability of trailer operation; Finally, vehicle frame can not be pulled distortion when carrying out trailer operation by the car puller hook be arranged on the longeron of automobile.
Summary of the invention
Problem to be solved in the utility model is to provide and is a kind ofly arranged on the longeron of automobile, and the vehicle frame of automobile can not be pulled distortion, and itself can not be out of shape fracture easily, structure is simple, firm longeron car puller hook easy to use.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of longeron car puller hook, comprise and be bent into U-shaped towing hook portion, interconnecting gangway and fixed base by round steel, the right side in the described towing hook portion of semicircular arc is fixedly connected with two parallel described interconnecting gangways, described fixed base is fixedly connected on the right side of described interconnecting gangway in obtuse angle, distance between two parallel described fixed base is two times of the diameter of described fixed base, and the right-hand member of described fixed base is provided with the connector be connected with the longeron of automobile.
Further, the obtuse angle accompanied between described fixed base and described interconnecting gangway is 150 ° to 170 °.
Further, the length of described fixed base is 2.5 times of the length of described interconnecting gangway.
Further, the internal diameter being bent into the described towing hook portion of semicircular arc is the half of external diameter.
Further, the outside face of described towing hook portion, described interconnecting gangway and described fixed base scribbles one deck zinc rete.
The advantage that the utility model has and good effect are: adopt technique scheme, adopt round steel to be bent into U-shaped the utility model and have the mechanical strength enough meeting trailer job requirements, solid firm; Be designed to semicircular arc with the trailer hook portion of traditional circle unlike towing hook portion of the present utility model, the towing hook portion of semicircular arc effectively can disperse stress point when drawing, and pulling of level is stressed more even, can not occur the problem of being out of shape fracture easily; The interconnecting gangway be provided with between towing hook portion of the present utility model and fixed base, and fixed base is fixedly connected on the design of interconnecting gangway in obtuse angle, the flexure stress acting on fixed base can be effectively reduced when pulling, two parallel fixed base are served as " cantilever beam ", stressed less on each root, removes the hidden danger that application force is too concentrated from; Fixed base of the present utility model is fixed on the longeron of automobile, vehicle frame can not be pulled distortion when carrying out trailer operation; Through experimental study display, when the obtuse angle accompanied between fixed base and interconnecting gangway is 150 ° to 170 °, what fixed base showed is stressed minimum, the angle that this angle is best suited for; The length of fixed base is 2.5 times of the length of interconnecting gangway, and the internal diameter in towing hook portion is the design of the half of external diameter, is all the stressed minimum design of the utility model of experimental study display, can not be out of shape fracture easily during use; The zinc rete that outside face scribbles contributes to the utility model withstanding corrosion more, and service life is more permanent.

Fig. 1 is structural representation of the present utility model.
In figure:
1, towing hook portion; 2, interconnecting gangway; 3, fixed base;
31, connector.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, the utility model provides a kind of longeron car puller hook, comprise and be bent into U-shaped towing hook portion 1, interconnecting gangway 2 and fixed base 3 by round steel, the right side in the described towing hook portion 1 of semicircular arc is fixedly connected with two parallel described interconnecting gangways 2, described fixed base 3 is fixedly connected on the right side of described interconnecting gangway 2 in obtuse angle, distance between two parallel described fixed base 3 is two times of the diameter of described fixed base 3, and the right-hand member of described fixed base 3 is provided with the connector 31 be connected with the longeron of automobile.
The obtuse angle accompanied between described fixed base 3 and described interconnecting gangway 2 is 150 ° to 170 °.
The length of described fixed base 3 is 2.5 times of the length of described interconnecting gangway 2.
The internal diameter being bent into the described towing hook portion 1 of semicircular arc is the half of external diameter.
The outside face of described towing hook portion 1, described interconnecting gangway 2 and described fixed base 3 scribbles one deck zinc rete.
The working process of this example: when installing the utility model, the connector 31 of fixed base 3 of the present utility model is connected with the longeron of automobile; When needs carry out towage to automobile, forceps horizontal pulling towing hook portion 1 both can complete traction.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
