Abstract

The utility model relates to a bush structure of a novel trunk cover goose neck type hinge, comprising a columnar bush body and a flange which is arranged on the columnar bush body, an axial gap is existed on a side wall of the columnar bush body. The section of the columnar bush body is C shape, and the position of the flange which is corresponded with the gap has a V shaped open. In the utilitymodel, because the gap is added on the closed ring bush, the size of the bush can be adjusted in small amount according to the size of the assembly aperture, thereby the installation is more convenient, the better fitting effect can be achieved, and the utility model has the advantages of low friction damping, low noise, low vibration and the like.

Description

A kind of bush structure of new suitcase lid gooseneck type hinge

Technical field

The utility model relates to a kind of bush structure, particularly relates to a kind of bush structure of new suitcase lid gooseneck type hinge.

Background technology

Lining usually is used to need the pivot pin of rotation relation and the position between the connected piece, it can reduce between pivot pin and connector because of rotating the frictional resistance that produces, reduce the noise and the abnormal sound that produce owing to friction, in addition, the lining of handling through special surface also has wear-resisting and antiseptic and rustproof effect.The bush structure that uses on the luggage compartment lid gooseneck type hinge of existing automobile is the enclosed type annulus lining 10 shown in Figure 1A, Figure 1B and Fig. 2 A, 2B.

Yet the closed circle bush structure requires than higher part precision, has only when accessory size and morpheme can be good at satisfying to cooperate when requiring, and can reach initial purpose of design.But, when the size of part and morpheme occur will causing a series of assembling or function problem when overproof.

Shown in Fig. 3 A, 3B, because dimension overproof, lining 10 produces with other part interferes, and frictional resistance was excessive when this situation can cause rotating, and was easy to generate noise, perhaps even can't assemble;

Shown in Fig. 4 A, 4B, because there is big gap in dimension overproof between lining 10 and other part, this situation will cause connecting loosening, produce vibration and abnormal sound during motion, thereby influence the normal function of built-up member.

In actual production and since the existence of various errors make part size and morpheme is difficult reaches than higher precision, also or in order to reach higher precision need introduce special equipment, method or technology, this has often all caused the increase of cost of parts.

The utility model content

The purpose of this utility model is, luggage compartment lid gooseneck type hinge bush structure commonly used is improved, make and used and to have carried out the small lining of adjustment voluntarily according to concrete mated condition, thereby overcome the deficiency of traditional luggage compartment lid gooseneck type hinge arrangement through the luggage compartment lid gooseneck type hinge after improving.The utility model provides a kind of bush structure of new suitcase lid gooseneck type hinge for this reason.

For achieving the above object, the utility model is taked following design scheme:

The bush structure of a kind of new suitcase lid gooseneck type hinge comprises the cylindrical spacers body and is arranged on flange on the described cylindrical spacers body, has axial slit on the sidewall of described cylindrical spacers body.

Preferably, described this body section of cylindrical spacers is the C type, and the opening that has V-type corresponding to the described flange in the position in described slit at described flange.

Preferably, described slit is two or more.Further, described two or more slit is that the center is symmetrical arranged with the axial of cylindrical spacers body.

The utility model has the advantages that: because the slit that the utility model increases on the closed circle lining, can make this lining self size be carried out trace adjusting according to the size in assembling aperture, thereby be convenient to install, can reach better fiting effect, and has a low frictional damping, low noise, advantages such as low vibration.

The specific embodiment

Referring to Fig. 5 A～Fig. 7 B, the preferred embodiment of the bush structure of a kind of new suitcase lid of the utility model shown in it gooseneck type hinge, comprise cylindrical spacers body 1 and be arranged on flange 2 on the described cylindrical spacers body 1, have axial slit 3 on the sidewall of described cylindrical spacers body 1.Whole cylindrical spacers body 1 is preferably run through in described slit 3.In the present embodiment, the cross section of described cylindrical spacers body 1 is the C type, shown in Fig. 6 A, 6B, 7A and 7B, and the opening 4 that has V-type corresponding to the described flange 2 in the position in described slit 3 at described flange 2, shown in Fig. 5 A and 5B.

Shown in Fig. 6 A and 6B, when the size of cylindrical spacers body 1 during greater than the assembling aperture, cylindrical spacers body 1 will be squeezed according to direction shown in the arrow among Fig. 6 A when mounted, under the effect of extruding force, trend adjustment self size that cylindrical spacers body 1 will reduce to diameter, at this moment, the annulus aperture slots 3 in " C " type cross section will diminish, and Fig. 6 B is the schematic diagram after slit 3 diminishes.

Shown in Fig. 7 A and 7B, when the size of cylindrical spacers body 1 during less than the assembling aperture, cylindrical spacers body 1 will be strutted according to direction shown in the arrow among Fig. 7 A when mounted, at this moment, cylindrical spacers body 1 will be to trend adjustment self size of diameter increase, the annulus aperture slots 3 in " C " type cross section will become greatly, and Fig. 7 B is the schematic diagram after slit 3 becomes greatly.

In addition, described slit 3 of the present utility model can also be two or more, and is not shown.Described two or more slit 3 is that the center is symmetrical arranged axially with cylindrical spacers body 1.This structure can be so that diminishing or becoming more even greatly of slit 3 makes that simultaneously tension force or pressure that cylindrical spacers body 1 is subjected to are also more even.

Obviously, those of ordinary skill in the art can constitute various types of bush structures with the bush structure of a kind of new suitcase lid gooseneck type hinge of the present utility model.

The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the utility model scope; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
