Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector used for connecting pipes at a connecting portion of the pipes.

[0002]

2. Description of the Related Art Conventionally, pipes such as PVC pipes are generally bonded and fixed using an adhesive. However, if a problem such as clogging occurs inside the pipe, the clogging is performed. It was necessary to cut the part and clean the inside. Therefore,
A method in which the ends of the pipes are bolted together with flanges (annular flange joints) so as to be detachably connected in a portion where frequent clogging is likely to occur without using an adhesive. Is adopted.

[0003]

However, the above-described connection method using a flange has a problem that a large number of bolts need to be attached and detached, and attaching and detaching the pipes requires a great deal of work. SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a pipe connector that can greatly reduce the labor and time required for pipe connection work and can reliably prevent the pipe from dropping off after connection. It is intended to do so.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a connector for connecting and fixing pipe ends to each other, wherein a pair of straps which are fixedly wound around each pipe to be connected are provided. It is characterized by comprising at least a pair of connecting rods arranged between the straps to connect the straps and extend and contract.

As the connecting rod, it is preferable to use a turnbuckle device having a length adjusting portion that expands and contracts by screwing and unscrewing a long bolt.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing a state in which straight pipes are connected to each other using a pipe connecting device according to the present invention, FIG. 2 is a plan view of FIG. 1, and FIG. Perspective view showing a state where the pipe and the curved pipe are connected,
FIG. 4 is a plan view showing a state where the pipe coupler according to the present invention is attached to the R portion of the pipe.

1 and 2, reference numerals 1 and 2 denote pipes made of vinyl chloride. At one end of one tube 2, an enlarged diameter opening 2 a whose diameter is slightly larger than the diameter of the connection end of the other tube 1 is integrally formed. Then, the connection end of the pipe 1 is fitted into the enlarged-diameter opening 2a to join the pipes 1 and 2 together.

The pipes 1 and 2 are straight pipes, and are usually joined by applying an adhesive to these joints. In this embodiment, the pipes are airtight or watertight without applying an adhesive. Through a packing (not shown) or the like.

In the figure, reference numeral 3 denotes a connecting device according to the present invention, which is provided between a pair of straps 4 wound around the ends of the tubes 1 and 2 and fixed, and between the pair of straps 4. And a turnbuckle device 5 which is a connecting rod configured to extend and contract. The metal band 4 of the connecting member 3 is formed by bending a tongue piece provided from each end of a band portion 4a divided into upper and lower halves so as to have substantially the same inner diameter as the diameter of the tubes 1 and 2 to be attached. 4b are fastened to each other by bolts 6a and nuts 6b.
Is fixed near the end.

Here, the tongue pieces 4b of the metal band 4 are connected to each other via a sliding plate 7 having an elliptical elongated hole 7a formed therein (that is, a sliding plate 7).
The sliding plate 7 is sandwiched between the upper and lower tongue pieces 4b, and the bolt 6a is inserted through the elongated hole 7a. The turnbuckle device 5 has an elongated hole 7 at one end thereof.
a pair of arm rods 5a each having a hook 5b engageable with the arm rod 5a and having a male screw formed over substantially the entire length from the other end, and a long nut 5c to which male threads of the arm rod 5a are screwed at both ends. A length adjusting portion is formed from the above, and by rotating this long nut 5c, the entire length thereof can be expanded and contracted.

At first, a pair of straps 4 are fastened and fixed to predetermined portions of pipes 1 and 2 to be connected, respectively, and then a turnbuckle device is attached to a long hole 7a of each slide plate 7. 5 hook 5b is engaged. In this state, the entire length of the turnbuckle device 5 may be reduced by tightening the long nut 5c of the turnbuckle device 5. This ensures that the tubes 1 and 2 are joined together.

The apparatus according to the present invention is effective not only for joining straight pipes but also for joining with a curved pipe 8 (see FIG. 3). In addition, as shown in FIG.
And the connection with the straight pipe 1 joined to its end (ie,
It is also effective to use it for the R portion of the pipe). In this case, it is preferable to support the straight pipe 1 with the support beam 10. In the above embodiment, a pair of (two) turnbuckle devices 5 as connecting rods are attached to the connecting member 3, but two or more turnbuckle devices 5 may be provided as necessary.

[0013]

Since the present invention is constructed as described above, the labor and time for connecting pipes can be greatly reduced, and the pipes can be securely prevented from falling off after connection. It has an excellent effect.
