Abstract

The utility model discloses a scalable detachable novel coupling, including hook body (1), hook neck (2), be equipped with on the hook body (1) trompil (11), realize the coupling through it with round pin (5) cooperation and be connected with outside drag hook, hook neck (2) leaves there are two hook lock pinholes, and one is work position hole (21), and one is shrink position hole (22), and equal accessible hook lock round pin (6) is connected with the coupler seat cooperation, shrink hole site (22) is close to hook body (1), sells (6) when its and hook lock and coordinates when being connected, and the coupling shrinks into inside the automobile body, hook body (1) is kept away from in work hole position (21), and when it was connected with hook lock round pin (6) cooperation, the coupling stretched out the automobile body. The utility model discloses a two hook lock pinholes of on -hook neck design are connected with the cooperation of hook lock round pin respectively, and design trompil of on -hook body portion and round pin cooperation realize that the coupling is flexible, exchange, can dismantle the function.

Description

A kind of scalable detachable novel hitch

Technical field

The utility model belongs to automobile mechanical field, particularly relates to a kind of scalable detachable novel hitch.

Background technology

Automobile tow hook be when automobile cannot automatic moving, connecting the device of automobile and external force equipment, is requisite accessory on automobile.In trailer process, hitch, coupler seat all bear larger tensile stress, so traditional hitch is in order to meet for the purpose of intensity, be all take coupler seat to be welded on undercarriage bea, and hitch are fixedly connected with coupler seat.Welding belongs to non-dismountable formula connection mode, although intensity is large, Shortcomings on the interchangeability in later stage, so be necessary a kind of scalable detachable hitch of design.

Summary of the invention

Goal of the invention: a kind of scalable detachable novel hitch of design, is convenient to flexible dismounting, increases flexible, interchangeability.

Technical scheme: a kind of scalable detachable novel hitch, comprise hook body 1, hook neck 2, described hook body 1 is provided with perforate 11, is coordinated realize hitch and be connected with outside drag hook by itself and pin 5; Described hook neck 2 has two hook lock pin-and-holes, and one is 21, one, working position hole is punctured bit hole 22, is all connected by coupler lock lift 6 and coupler seat; Described shrink hole position 22 near hook body 1, when it and coupler lock lift 6 is connected time, hitch will shrink into vehicle body; Described working hole position 21 away from hook body 1, when it and coupler lock lift 6 is connected time, hitch stretches out car body, realize hitch flexible, exchange function;

After coupler lock lift 6 is extracted completely, being separated of hitch and coupler seat can be realized, realize detachable function;

Described coupler lock lift 6 is gone back available open pin 7 and is fixed, and prevents coupler lock lift in vehicle operation from jumping out.

Whole structure of couplers adopts detachable pin to connect, and the shear strength of described coupler lock lift 6 is very high, intensity required when can ensure trailer.

The beneficial effects of the utility model: the utility model, by being connected with coupler lock lift respectively at hook neck portion design two hook lock pin-and-holes, coordinates with pin in the design perforate of hook body portion, realize that hitch is flexible, exchange, detachably function.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Embodiment: as Fig. 1 ~ 3, a kind of scalable detachable novel hitch, comprise hook body 1, hook neck 2, described hook body 1 is provided with perforate 11, is coordinated realize hitch and be connected with outside drag hook by itself and pin 5; Described hook neck 2 has two hook lock pin-and-holes, and one is 21, one, working position hole is punctured bit hole 22, is all connected by coupler lock lift 6 and coupler seat; Described shrink hole position 22 near hook body 1, when it and coupler lock lift 6 is connected time, hitch will shrink into vehicle body; Described working hole position 21 away from hook body 1, when it and coupler lock lift 6 is connected time, hitch stretches out car body, realize hitch flexible, exchange function;

As Fig. 4, described coupler lock lift 6 is gone back available open pin 7 and is fixed, and prevents coupler lock lift in vehicle operation from jumping out.

The foregoing is only preferred embodiments of the present utility model, not in order to limit the present invention, any amendment done within the spirit and principle of invention, equivalent replacement, improvement etc., all should be included within system architecture of the present utility model.
