[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved eyelet for detachably attaching a cover to a main body without using fastening means such as screws and clips.

[0002]

2. Description of the Related Art In a recent diesel engine for a vehicle, in order to reduce a sound emitted from a fuel injection nozzle N disposed on a cylinder head H as shown in FIG. A synthetic resin nozzle cover Nc is provided between the cylinder head cover Hc and the intake manifold M so as to cover the injection nozzle, and is attached to the head cover and the manifold at a plurality of locations at both ends. In order to maintain the engine without using any tightening means, the following means have been used for attaching and detaching the nozzle cover without using a tool.

[0003] That is, at one end side (cylinder head cover side) of the nozzle cover Nc, a horseshoe-shaped cover end side is opened on the inner surface of the cover end as shown in FIG.
A plurality (shown only one in Fig. 4) is provided, in the bottom wall b ₁ of each bag b collar shape at predetermined intervals bag b of the required height to form a slit b ₂ in ₁ center, an elastic member made of such soft rubber, eyelet member a having a recess a ₂ constricted along the periphery and has an insertion hole a ₁ pin p to the central portion forms a horseshoe shape
The constriction fitted respectively in fitting the recess a _2, and their eyelet member a bound at I pushed from above into the pin p provided on the end of the cylinder head cover Hc.

On the other end side (intake manifold side) of the nozzle cover Nc, as shown in FIG. 5, a plurality of vertical recesses d having a semi-elliptical front surface and open front and lower sides are formed at the edge of the cover. It is formed at a predetermined interval, and a horizontal U-shaped overhanging collar e is provided at the lower end of each vertical recess d, and the eyelet member a is attached to the narrow recess a ₂ is fitted and attached from the front side, and each eye member a is pushed into the pin p provided on the end of the manifold M from above to be connected.

[0005]

The eye member a is made of an elastic material such as a soft rubber or a synthetic resin so as to absorb vibration and sound of the engine, and eliminates rattling of the joint. because it to be mounted on the pin p to the compressed state of the insertion hole a ₁ and slightly smaller than the pin diameter in order, when pushing the grommet member a to the pin p, often under as in FIG. 6 side portion is pushed by the head of the pin p curved deformation, up burr is open side portion as shown in FIG. 7 by the subsequent pushing action, the overhanging flange e or bag of longitudinal recesses exit the slit b ₁ Would. The upper portion of this when escape is where the axes of the insertion hole a ₁ pin p is deviated, frequently occurs, and the grommet member a when detached from the pin p to lift the nozzle cover Nc for engine maintenance Are deformed and come off similarly.

[0006] Therefore, in the present invention, when attaching and detaching the cover,
An object of the present invention is to prevent the eyelet member from easily coming off the mounting place.

[0007]

SUMMARY OF THE INVENTION In view of the above-mentioned object, the present invention provides a pin-shaped hole made of a flexible elastic material at the center and a concavity along the periphery at the center in the height direction. It is characterized in that a perforated reinforcing plate having rigidity is fixed to the upper and lower surfaces of the eyelet.

[0008]

1 and 2 show an embodiment of the present invention. Reference numeral 1 denotes an eyelet mainly made of an elastic material such as a soft rubber or a synthetic resin. Is provided with a pin insertion hole 1a in the height direction, and a concavity 1b is formed in the center in the height direction along the periphery in a U-shape to form a front E-shape. U in place d
The inwardly extending flange e or the bottom wall slit of the bag body is fitted to the upper and lower surfaces of the eyelet main body 1. Metal or a hard synthetic resin such as phenol or nylon A rigid perforated reinforcing plate 2 having rigidity and the like is fixed by baking or fusing.

At the time of use, the constricted recess 1b of the retainer main body 1 is inserted into the protruding collar e in the vertical recess d at the end of the nozzle cover or the bottom wall slit. Then, the eye member is attached to the cover, and the insertion hole 1a of the retainer main body 1 overlapping the central hole of the reinforcing plate 2 is provided with the pin p provided on the intake manifold M or the cylinder head cover Hc. And the nozzle cover Nc is connected to the engine as shown in FIG.

When the engine is maintained, the nozzle cover N
By lifting the end of c upward, the eyelet member is pulled out from the pin p, and the nozzle cover Nc is removed from the engine. When attaching or detaching the nozzle cover Nc, the rigid reinforcing plate 2 is attached to both sides of the flexible eyelet 1, so that the eyelet 1 does not bend and deform as in the past, The escape is prevented.

In the illustrated example, the eyelet member is formed in a horseshoe shape. However, the eyelet member may be circular, and in the illustrated example, it is described as being used for mounting an engine nozzle cover. The present invention is not limited to this, and can be applied to a cover that facilitates attachment and detachment and prevents transmission of vibration and noise from the main body side.

[0012]

As described above, according to the present invention, the eyelet for attaching the cover without using the fastening means is made of a flexible elastic material, has a pin insertion hole at the center, and has a height direction. In the center, a perforated reinforcing plate with rigidity was fixed to the upper and lower surfaces of the eyelet with a constricted recess along the periphery, so when using it, push the eyelet member into the pin, Even if it is pulled out, the eyelet member is prevented from falling off without being curved and deformed as in the past, and the cover can be quickly attached and detached without any trouble. And it can be used for a long time without being damaged.
