Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compressor, and more particularly to a compressor configured to integrally connect a compressor body and a tank.

2. Description of the Related Art For portable compressors used as power sources for nailing machines, coating devices, etc., for example, at construction sites, painting sites, etc., there is a strong demand for downsizing and weight reduction. Therefore, the conventional compressor employs a structure in which a compressor body that generates compressed air and a tank that stores compressed air are integrally connected.

A conventional compressor of this type is shown in FIG. In FIG. 4, in a conventional compressor, a piston (not shown) in a cylinder 1 is driven to extend upward and downward to a side portion of a compressor body 2 which generates compressed air by reciprocating motion of the piston. The fixture 3 is fixed by welding or the like. A U-shaped bracket 5 is fixed to a side portion of the tank 4 in which the compressed air generated by the compressor body 2 is accumulated.

The fixture 3 and the bracket 5, which are interposed between the compressor body 2 and the tank 4, are integrally coupled by tightening the bolt 6.

The problem to be solved by the invention is that, in the compressor, as shown in FIG. 4, a plurality of connecting members such as the fixture 3 and the bracket 5 are interposed between the compressor body 2 and the tank 4, Therefore, the distance between the two must be increased, which causes a problem that the miniaturization of the compressor is hindered. Furthermore, since the fixture 3 extends in the upward and downward directions, if the distance between the compressor body 2 and the tank 4 is shortened to achieve size reduction, the fixture 3 and the compressor body 2 Since and are close to each other, there is a disadvantage that the tightening work of the bolt 6 becomes difficult.

Another conventional example is a compressor as disclosed in Japanese Utility Model Laid-Open No. 55-177592. For this compressor,
Although the compressor body and the tank are connected by a pair of connecting plates, the compressor body and the tank are connected so that the cylinder protrudes in the direction opposite to the tank side, so it is possible to reduce the size. Can not.

Then, this invention aims at providing the compressor which solved the said subject.

Means for Solving the Problems The present invention is directed to a tank formed in a substantially cylindrical shape and storing compressed air, and a compression member formed in a substantially cylindrical shape and extending in a direction parallel to the tank. The main body of the compressor, a cylinder having a piston that projects compressed air from the outer circumference of the compressor main body in the direction closer to the outer circumference of the tank, and the direction in which the compressor main body and the tank are parallel to each other. And a pair of mounting bases provided on the outer periphery of the compressor body or the outer periphery of the tank and at a predetermined angle so as to be mounted on the pair of mounting bases. It has a pair of mounting parts formed in an open shape at both ends, and has a fixing part fixed to the outer circumference of the tank or the outer circumference of the compressor body, and the pair of mounting bases are mounted on the mounting parts at both ends. Fixed to And a coupling member having a hole for connecting.

Action By fixing the pair of mounting parts formed in a shape opened at a predetermined angle to the pair of mounting bases, it is possible to mount the compressor body and the tank as close to each other as possible. In addition to the shorter width, the cylinder can be positioned so that it is tilted so that it is as close to the tank as possible, and the tank and compressor body can be connected in that state, and the cylinder height protruding from the compressor body can be reduced. The height of the compressor can be reduced, and the size in the height direction can be reduced. As a result, the entire compressor can be made compact.

Embodiment FIG. 1 and FIG. 2 show an embodiment of the compressor according to the present invention.

In both figures, the compressor 11 is a portable air compressor that can be easily moved to the site where it is used, and connects the compressor body 12 having the cylinder 20 and the tank 13 with the connecting member 14, the mounting base 15a, It is configured to be coupled by a coupling mechanism composed of 15b.

The tank 13 is a columnar closed container, and is provided so as to extend in the horizontal direction. Further, inside the compressor body 12, a motor for reciprocating a piston (not shown) in the cylinder 20 and a part of a crank mechanism are housed.
The appearance is formed in a substantially cylindrical shape. The compressor body 12 is provided so as to be parallel to the tank 13.

The cylinder 20 projects in the radial direction from the outer circumference of the compressor body 12, and the projection direction hinders size reduction. Therefore, the cylinder 20 is attached so as to be inclined to the tank 13 side so as to be as close as possible to the tank 13. This also reduces the height dimension of the cylinder 20,
The entire 11 can be made compact.

As shown in FIG. 3, the coupling member 14 is bent at the upper and lower ends of the fixed portion 14a at an angle inclined in a direction away from the tank 13 and extends in a "C" shape so as to open at a predetermined angle. Mounting portions 14b and 14c are provided.

That is, the coupling member 14 includes a fixing portion 14a fixed to the outer periphery of the tank 13 by welding, and a compressor body 12 from the upper end of the fixing portion 14a.
The first mounting portion 14c that extends above the outer periphery of the compressor and is fixed to the upper mounting base 15b, and the lower end of the fixing portion 14a.
A second mounting portion 14b that extends below the outer periphery of the first mounting portion 15a and is fixed to the lower mounting base 15a.

Further, since the fixing portion 14a of the coupling member 14 is fixed to the outer periphery of the tank 13 in a state of being in close contact, it is formed in an arc shape corresponding to the outer periphery of the tank 13, and the mounting portions 14b and 14c have a pair of mounting bases. A notch 14d is formed as a hole for fixing to. The notch 14d is provided at the tip of each of the mounting portions 14b and 14c, two U-shaped holes each being provided in total. Notch 1
The 4d is not limited to the U-shaped notch, and may have an oval hole.

When viewed from above (see FIG. 2), the connecting member 14 is fixed to the tank 13 substantially at the center in the longitudinal direction.

Further, the compressor body 12 has a mounting portion 1 so as to abut the mounting portions 14b and 14c of the coupling member 14 on the outer periphery of the center in the longitudinal direction (axial direction).
It has a pair of mounting bases 15a, 15b protruding at an angle corresponding to the inclination angle of 4b, 14c. Then, four stud bolts 16 are screwed onto each of the mounting bases 15a and 15b, two studs 16 each.

Therefore, when integrally connecting the compressor body 12 and the tank 13, the stud 16 is inserted into the notch 14d of the connecting member 14 fixed to the tank 13, and the nut 17 is screwed into each bolt 16. Let Then, by tightening the nut 17 with a tool such as a wrench, the mounting portions 14b, 14c of the coupling member 14 are fixed to the mounting bases 15a, 15b of the compressor body 12, and as a result, the compressor body 12 has a "C" shape. Mounting parts 14b, 14c of the connecting member 14 opened to the
Held in.

In this way, when the compressor body 12 and the tank 13 are coupled by the coupling mechanism having the above configuration, the cylinder 20 and one side surface are positioned in a tilted state so as to approach the outer peripheral surface of the tank 13 as much as possible. Since it will be installed in the state, it has a more compact structure.

Moreover, since the pair of mounting portions 14b, 14c of the coupling member 14 are inclined toward the compressor body 12 side, the mounting portions 14b, 14c and the tank 13 are
Is not so close to each other, and a relatively large space is formed around the nut 17. Therefore, the tightening work when tightening the nut 17 is easy. Further, as described above, the tightening workability of the nut 17 is improved, and the compressor body 12
The distance between the tank 11 and the tank 13 can be reduced so that the tank 13 and the tank 13 can be closer to each other than before, and the compressor 11 can be downsized.

That is, since the tank 13 and the compressor body 12 are connected to each other by the connecting member 14 that is opened in a “C” shape, the compressor body 12 and the tank body are connected.
It becomes possible to attach 13 and 13 as close as possible. As a result, the width dimension of the compressor body 13 is shortened, and the tank 13 and the compressor body 12 are connected in a state where the cylinder 20 is inclined so as to be as close to the tank 13 as possible. The height of the cylinder protruding in the vertical direction can be reduced, and the dimension in the height direction can be reduced. As a result, the entire compressor 11 can be made compact.

Further, in the compressor 11, since the joining member 14 is interposed between the compressor body 12 and the tank 13 to integrally join the two, the number of joining members can be smaller than that of the conventional one, and the corresponding amount is required. Weight reduction can be achieved.

After that, with the rubber leg 19 attached to the bottom of the compressor body 12 and the U-shaped handle 18 fixed to the tank 13 placed down, the silencer for sucking air into the side surface of the cylinder 20. Device 21, an air pipe 22 connecting the cylinder 20 and the tank 13,
Condenser 23 such as pressure gauge, pressure reducing valve, safety valve, etc., compressor body 12
Each member such as a blade 24 for air cooling is attached.

As described above, since the mounting portions 14b and 14c of the rare member 14 are inclined toward the compressor body 12 side, the space between the nut 17 and the tank 13 can be made different from each other as shown in FIG. A container 23 or the like can be provided. As a result, the size of the compressor 11 can be further reduced.

In the above embodiment, the connecting member 14 is fixed to the tank 13 by welding or the like, but the connecting member 14 is fixed to the compressor body 14 so that the mounting portions 14b and 14c are fastened to the tank 13 side with the nut 17 or the like. You can

Further, although the stud bolt 16 and the nut 17 are used in the above embodiment, the present invention is not limited to this. For example, the mounting bases 15a and 15b are provided with female screws, and the coupling member 14 is fixed to the mounting bases 15a and 15b by bolts. You may do it. In that case, the mounting portions 14b and 14c of the coupling member 14 may be provided with holes through which the bolts pass, instead of the U-shaped notches.

Effect of the Invention As described above, in the compressor according to the present invention, the compressor main body and the tank are brought as close as possible to each other in order to fix the pair of mounting portions formed in a shape opened at a predetermined angle to the pair of mounting bases. It can be installed in a state that the width dimension of the compressor is shortened and the cylinder can be positioned in a tilted state so as to be as close to the tank as possible and the tank and the compressor body can be connected in that state. . Therefore, the height of the cylinder protruding from the compressor body can be reduced, and the dimension in the height direction can be reduced. As a result, the entire compressor can be made compact. Further, since the number of parts interposed between the compressor body and the tank can be reduced as compared with the conventional one, the size and weight can be reduced. further,
Since a large space can be taken around the mounting part of the coupling mechanism,
It has features such that bolts or nuts can be easily tightened even if the compressor body and the tank are brought close to each other.
