It is an expanded sectional view of a split connection part. The parts corresponding to those in FIG. 1 are denoted by the same reference numerals.

In these figures, swivel elbow 2
0 (21) is an elbow main body 41 and this elbow main body 41
Adapter part 42 that connects one side of
And the other side of the elbow main body 41 to the oil supply hose 13 (15).
And a second adapter 43 connected to the end of
A cover 51 is provided on the front side of the pillar 17 (18) through a hole 17a (18a) formed slightly larger than the outer shape of the first adapter portion 42, and around the swivel elbow 20 (21). ing.

The first adapter part 42 is made of a metal or the like and is formed in a short tubular shape. One end of the first adapter part 42 is in contact with a flange part 34 a formed at the end of the oil supply pipe 34, and is bolted by a bolt 44. A flange portion 42a to be tightened is formed, and the outer end portion on the other end side is formed to have a small diameter and a large diameter, and O for preventing oil leakage is formed in a groove formed around the small diameter portion.
A ring 45 is provided, and a groove 42b is formed around a large diameter portion thereof.
Are formed.

The second adapter portion 43 is made of a metal or the like, and is formed in a short tubular shape. The second adapter portion 43 is formed with an inclined portion 43a having a smaller outer diameter at one end toward the end. The inner diameter side is connected to the end of the oil supply hose 13 (15) by a fastening structure or the like, and the other end side is formed with a screw portion 43b connected to the elbow main body 41.

The elbow main body 41 is made of a metal casting or the like, and is formed in a substantially L-shaped tubular shape, and the small-diameter and large-diameter outer portions of the first adapter portion 42 are wound around one end. A small-diameter and a large-diameter hole movably fitted is formed, and the groove 42b of the first adapter portion 42 is inserted into the large-diameter hole from the outside.
A screw hole is formed through the screw hole so as to prevent the screw from slipping into the groove portion 42b, and a guide groove 41a is formed around the outer portion close to the screw hole. Formed on the other end side,
A screw portion 41b into which the screw portion 43b of the second adapter portion 43 is screwed is formed, a packing 47 is provided at an end of the second adapter portion 43, and a groove formed in an outer peripheral portion around the screw portion 41b. An O-ring 48 is provided for abutting an inner surface of a cover 51 described later to prevent vibration.

That is, the swivel elbow 20 (21)
The elbow body 41 is connected to the first adapter part 42 with the screw 4
At 6, oil is prevented from leaking by the O-ring 45, and oil is prevented by the packing 47 at the second adapter 43 side.

The cover 51 is made of plastic or the like, and is formed in a substantially L-shape to cover the periphery of the elbow main body 41 and is divided into two parts. In the cover 51, an outer diameter portion 51a having a slightly larger diameter is formed on an outer portion covering the elbow main body 41 on the first adapter 42 side, and several grooves 51b for giving a three-dimensional effect are formed around the outer diameter portion. And
On the inner surface side, protrusions 51c which are in contact with the end surface and the outer surface of the elbow main body 41 to prevent vibration and also serve as reinforcement are formed at four places away from the separation line of the cover 51, and the screws 46
A screw hole 51d for removing the screw 46 when the oil supply hose 13 (15) is replaced is formed in a portion facing the guide groove 41a, and the guide groove 41a is formed in an inner surface portion facing the guide groove 41a.
Are formed at four places apart from the separation line in the same manner as the protrusions 51c.
The connection part 51f formed in the same shape is provided on the side, the second adapter part 43 side, and the split part of the L-shaped part. The connecting portion 51f has a projection 51g on one side and a groove 51h into which the projection 51g is engaged on the other side, of a portion where the two portions overlap each other.
For example, the groove 51h of the connecting portion 51f in the enlarged diameter portion 51a.
By applying a force in the direction of arrow A from the outside on the side where is formed to deform inward against the elastic force of the plastic, the connection can be released and the halves can be separated. At this time,
Since the projections 51c and 51e are formed at positions away from the separation line, they are not obstructed by the elbow main body 41,
The connecting portion 51f can be deformed.

The cover 51 is attached to the swivel elbow 20 (2
At the time of mounting in 1), the two parts are separated and fitted from both sides of the elbow main body 41, the enlarged diameter portion 51a side is slightly inserted into the hole 17a (18a), and the projection 51c is inserted into the end face of the elbow main body 41 and The projection 51e is engaged with the guide groove 41a, and the projection 51g of the connecting portion 51f is engaged with the groove 51h. The periphery of the second adapter part 43 is covered with a soft cover 52 made of vinyl chloride or the like.

In the lubricating apparatus 11 having the above structure, the left and right columns 1
One end side of the refueling hoses 13 and 15 is connected to the refueling pipe 34 via the swivel elbows 20 and 21 on the upper portions of the refueling hoses 7 and 18, and covers around the swivel elbows 20 and 21.
Since dust and rainwater do not enter the rotating portion between the elbow main body 41 and the first adapter portion 42, rust and the like are prevented and smooth rotation is maintained.
15 operability could be improved. Also, cover 5
1 is formed in two, so that it can be easily attached and detached, and the projections 51c and 51e are locked around the elbow main body 41, and the O-ring 48 is also in contact with the inner surface of the cover 51. The mechanical vibration (play) was eliminated. Further, when replacing the refueling hoses 13 and 15,
By removing the screw 46 from the screw hole 51d formed in the enlarged diameter portion 51a without removing the cover 51, the swivel elbows 20 and 21 can be removed from the first adapter portion 42. It can be located inside the pillar 17 and can further prevent intrusion of dust and rainwater.

In the above embodiment, the shape of the cover 51 is not limited to the shape of the embodiment, as long as it covers at least the periphery of the swivel elbows 20 and 21 and can be easily attached and detached. Also, the example in which the refueling device 11 includes the three refueling hoses 13, 14, and 15 having one ends connected to the left and right pillars 17, 18 and the upper case 19 has been described. The attachment position and rotation direction of the elbow can be arbitrarily set, and are not limited to the embodiments.

[0021]

As described above, according to the present invention, the lubricating pipe is connected to the lubricating hose via the swivel elbow and led out of the lubricating apparatus main body, and the swivel elbow is covered with a cover. There is an effect that dust and rainwater can be prevented from entering the rotating portion of the elbow, and smooth rotation can be maintained. Also, if the cover is formed in two parts and the connection part is formed in two parts, the attachment and detachment of the cover becomes easy, and if the screw holes are formed, the replacement of the oil supply hose becomes easy.
