The first joint 12 includes a body having a generally meandering shape, and has a base portion 121 and a 7" side, 122 extending from both sides of the base portion 121, and one end of the base portion 121 (inside) The end portion is coupled to the connecting end 31 of the gas tube 3 or the pressure gauge 4; in the embodiment, the side 122 is extended from the short side of the outer end surface of the base portion 121, and the side wall There is a __second distance d2 between 122, the second distance d2 is also equal or slightly smaller than the distance dl between the second side 111 11111165 of the first joint 11; the base 121 and the A receiving groove 124 is defined between the two side walls 122. The outer end of each of the side walls 122 extends perpendicularly to the receiving groove 124. A flange 123 is further disposed in the receiving groove 124 of the second joint 12. A column 126 extends from the outer side of the base 121, and a sealing ring 127 is disposed around the outer periphery of the column 126 (see the fourth figure). Referring to Figures 5 and 6, which show that the pressure gauge 4 is to be connected to the exhaust base 10, the corresponding groove 13 of the second joint 12 provided on the pressure gauge 4 is inserted into the corresponding manifold 13 The outer end 132, when nested, the two side walls 122 of the second joint 12 are offset from the first side 111 of the first joint 11 and the surface 41 of the pressure gauge 4 faces one side; The pressure gauge 4 is rotated in the direction of the arrow in the sixth figure; since the first corner 113 is formed in an arc shape, the two side walls 122 of the second joint 12 can pass through the first corner 113 and are opposite to the first joint 11 Rotating in the clock direction; when the two side walls 122 of the second joint 12 are moved to the outside of the first side 111 of the first joint 11 , the second distance d2 between the two side walls 122 is equal or slightly smaller than the second side The first distance d1 between the first side edges 111 of the two joints 11 is such that the inner wall surface and the two flanges 123 of the two side walls 122 are formed and fixed with the two first side edges 111, as shown in the fourth figure. A combination cross-sectional view of the first joint 11 and the second joint 12 is shown; in this combined state, the surface 41 of the pressure gauge 4 is aligned It is easy to observe when facing up. The compressed air output by the manifold 13 can also act on the pressure gauge 4 by the passage 128 of the tubular string 126 provided on the second joint 12 and exhibit a pressure value. Since the second corner 114 does not form a large arc or a chamfered corner, when the two side walls 122 of the second joint 12 are rotated to form a fitting on the outer side of the first side ill of the first joint 11 11 201011165 The second corner 114 can block the second joint 12 from continuing to rotate and form a positioning; when the pressure gauge 4 is reversed in the direction of the arrow in the sixth figure, the two side walls 122 of the second joint 12 can be from the fourth figure. The chucking position is shifted to the release position of the fifth figure such that the first joint 12 can be separated from the first joint 11 to disassemble the waste force meter 4. The assembly of the inflatable tube 3 is similar to the assembly of the pressure gauge 4 described above; the receiving groove 124 of the second joint 12 is inserted into the outer end 132 of the corresponding manifold 13 and then the second joint 12 is rotated to make the two side walls The .122 and the first side edge m of the first joint 11 of the crucible are fitted to each other, which is quite advantageous. Of course, the pressure relief valve 7 is also assembled in the same manner. Referring to the fourth figure again, it is shown that when the inflation tube 3 and the pressure gauge 4 are connected to the outer end 132 of the corresponding manifold 13 of the exhaust manifold device 1, the seal ring 127 is in close contact with the inner wall of the manifold through hole 131. 'To ensure gas delivery within the compression cylinder 22. On the other hand, the structure of the cover 14 of the present invention is completely identical to the structure of the second joint 12 described above, and is further provided with a base portion 141, a side wall 142, a flange 143, and a receiving groove 144, so that the cover 14 can also be coupled to the row. On the other side of the air base 1 as a spare manifold 13, as shown in the fifth figure, in order to facilitate the rotation of the cover 14, a convex rib 140 is provided on the outer end surface of the base portion 141. The air compressor 2 constructed according to the present invention, by means of the design of the exhaust manifold device 1, not only allows the various functional components that may be used, such as the inflation tube 3 for connecting the inflation nozzle, the pressure gauge 4 or the vent The pressure valve and the like can be conveniently assembled on the compression cylinder 22 of the air compressor, and at the same time, the position where the functional fittings such as the inflation tube 3, the pressure gauge 4 or the pressure relief valve 7 are locked on the manifold 13 can be surely located at a predetermined position. The present invention has achieved the intended design and implementation effects of the design 12 201011165. The air compressor as a whole can be accommodated in the upper and lower casings 20, 21, and the upper and lower casings 20, 21 (refer to the first and seventh figures) are respectively provided with positioning bolts (in the figure) Not shown) the fixed screw posts 203, 21 so that the air machine is hidden in the upper and lower casings 20, 21, since the upper casing 20 is additionally provided with ribs 201, 202, After the lower casings 20, 21 are combined, the ribs 201 can also be pressed against the second joint 12 and the cover 14 as shown in the first figure, and the ribs 202 can be pressed against the back of the functional fitting pressure gauge 4. Nothing will cause looseness and detachment. The foregoing is a description of the preferred embodiments of the present invention, and the embodiments of the invention may be modified or modified. Therefore, obvious substitutions and modifications may be made by those skilled in the art, which are still within the scope of the claimed invention. 13 201011165 [Simplified description of the drawings] The first figure is a perspective view of an air compressor constructed in accordance with an embodiment of the present invention, and shows that the air compressor is housed in a casing.
