Description

A kind of hook assembly

Technical field

This utility model relates to a kind of hook assembly, belongs to technical field of automobile parts.

Background technology

At present, the hook of automobile mainly has two kinds of settings, and the first is direct one hook of arrangement in the middle part of the front side of frame front cross beam, and the second is directly to be respectively welded a hook in the left and right sides of front section of vehicle frame bottom surface.

Shown in the first hook setting such as Chinese utility model patent " on 07 22nd, Authorization Notice No.: CN204488932U; authorized announcement date: 2015; entitled: an a kind of novel crossbeam ", its hook is to be placed on front beam by being placed on front side of front beam the traction seat at middle part, it is limited to its fault of construction, there is, with the junction of front beam, the situation that stress is concentrated in hook seat, this hook is not high enough with the bonding strength of front beam, it is difficult to bear relatively large traction.

The second way respectively arranges a hook in the both sides of front section of vehicle frame, actually used during, easily there is unbalanced situation in the stress of two hooks, and single hook cannot meet the requirement of rated drawbar pull.Further, the hook that both sides are arranged is limited to headlight, bumper, front lower protection etc., narrow space, and the activity point of view of haulage cable exists can not meet regulation and user uses the situation of demand.

Summary of the invention

The purpose of this utility model is unreasonable with the fixed connection structure of vehicle frame for existing hook, there is bonding strength not high enough, it is difficult to bear relatively large traction, and the activity point of view of haulage cable is limited, it is impossible to meet the defect of regulation and user's request, it is provided that a kind of hook assembly, the modern design of this hook assembly, bonding strength is high, can meet large traction requirement, and the activity point of view solving existing haulage cable is unsatisfactory for the defect of regulation and user's request.

For achieving the above object, technical solution of the present utility model is:

A kind of hook assembly, it includes hook body and hook base, it is correspondingly provided with bolt hole on described hook body and hook base, after both are bolted to together, between described hook body and hook base, split forms a through hole matched with frame front cross beam, this through hole and front beam interference fit.

Further, described hook base is fixed in the middle part of the rear side of front beam.

Further, described front beam is pipe beam or trough girder.

Further, described hook base is platy structure, is provided with the bathtub construction matched with front beam in the middle part of it, and its epipleural face is provided with the installing port about quick release valve, loudspeaker and pipeline.

Further, described hook body is by hook connecting plate and is juxtaposed on two hook posts of hook connecting plate side and forms, and described hook connecting plate is smoothly transitted by arcuate structure with the junction of hook post；The end of described two hook posts is correspondingly provided with the pin-and-hole for disposing traction hook pin, and the traction hook pin through this pin-and-hole is fixed by split pin, and the aperture of this pin-and-hole is provided with reinforcing annular boss.

Further, the opposite side of described hook connecting plate is provided with the trench structure matched with front beam.

Further, the hook connecting plate between described two hook posts offers lightening hole.

Further, the bolt hole aperture on described hook body and hook base is equipped with reinforcing annular boss.

Compared with prior art, the beneficial effects of the utility model are:

Hook assembly the most provided by the utility model is made up of hook body and hook base, both are after bolt is fixed together, tightly encircle on front beam, the hook assembly of this structure not only may be implemented in fixing on multiple crossbeam (pipe beam or trough girder), but also increase the contact area of hook and crossbeam, avoid the situation of the power concentrations acted on crossbeam, there is bonding strength high, the advantage that relatively large traction can be born；

2. hook base is fixed on the rear side of front beam, can effectively prevent hook moving left and right on front beam；

3. the hook base in this utility model is platy structure, is provided with the bathtub construction matched with front beam in the middle part of it, it is simple to be fixed on front beam by hook base；

4. the epipleural face of hook base is provided with the interface about quick release valve, loudspeaker and pipeline, while ensure that hook assembly structure intensity, also provides installation position for multiple elements, has prominent practicality；

5. this utility model is provided with annular reinforcement boss at the aperture of bolt hole and pin-and-hole, is effectively improved the structural strength of hook assembly.

Detailed description of the invention

Illustrate with specific embodiment, this utility model to be described in further detail below in conjunction with accompanying drawing.

See Fig. 1 to Fig. 8, a kind of hook assembly, it includes hook body 4 and hook base 3, it is correspondingly provided with bolt hole on hook body 4 and hook base 3, after both are bolted to together, between hook body 4 and hook base 3, split forms a through hole matched with frame front cross beam 2, this through hole and front beam 2 interference fit.The hook assembly of this structure, can be simultaneously suitable for the fixed installation on pipe beam and trough girder, and it is big to have contact area, the advantage that bonding strength is high.

As preferred technical scheme, hook base 3 is fixed in the middle part of the rear side of front beam 2, prevents hook from horizontally slipping on front beam 2.

As preferred technical scheme, hook base 3 is platy structure, is provided with the bathtub construction 31 matched with front beam 2 in the middle part of it, is conveniently fixed on front beam 2 by hook base 3；The epipleural face of hook base 2 is provided with the installing port about quick release valve, loudspeaker and pipeline, makes the hook assembly of this structure have prominent practicality.
