Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cylinder connecting device used for connecting intake and exhaust cylinders in a heater, for example.

Conventionally, as shown in FIGS. 1 and 2, a device of this type has been constructed by bending a metal plate or other strip plate a into a substantially annular shape as a whole, and forming outwardly bent tongues b at both ends thereof. A type in which a bolt nut or other tightening member C is applied between both tongue pieces A and B is known, but in this case, both tongue pieces A and B are
is generally bent at lines d and d that are substantially perpendicular to the length direction of the strip a, and in the case of a bending type, for example, as shown in Figure 3, this is bent by a relatively large diameter tube. When applied to the outer periphery of the mutually fitting ends of the body A and the comparatively small diameter cylinder B, the small diameter cylinder B does not come into contact with the band plate a due to the step C between the two cylinders AB. , thus this has the disadvantage of being easy to remove.

Conventionally, in order to prevent this, a method has been proposed in which an inward protrusion e is formed in advance on the band plate a at a position opposite to the step C, as shown in FIG. In this case, it is inevitable that forming the protruding portion e is time-consuming and troublesome.

The purpose of the present invention is to obtain a device free of such inconveniences, and the purpose of the present invention is to provide a device in which a metal plate or other strip plate 1 is bent into a substantially annular shape as a whole, and tongue pieces 2 bent outward at both ends thereof are provided. In the case of a type in which a bolt/nut or other fastening member 3 is applied between both tongue pieces 2. 4
As shown in Fig. 8, this device is designed to surround the ends of a large-diameter cylinder A and a small-diameter cylinder B where they fit together. When the attachment member 3 is tightened, the strip plate 1 is first tightened to the outer periphery of the large-diameter cylinder A, and when it is further tightened, the strip plate 1 is attached to the cylinder A side as a fulcrum as shown by the dashed line. The belt plate 1 is tilted as shown in FIG.

5 to 8 show an example of its implementation. In this embodiment, both tongues 2, 2 are of an inclined type bent along diagonal lines 4, 4, as will be described later. When the difference in level between both cylinders is small, only one of them can be of the inclined type.

As described above, according to the present invention, it is sufficient that at least one of the tongues 2, 2 is of the inclined type, and there is no disadvantage of the conventional type described above, and the effect can be obtained easily and inexpensively.
