The fastening part 6 is provided on the other side of the hinge of the first housing 2a and the second housing 2b to selectively separate or fix the first housing 2a and the second housing 2b. Can be.

The fastening part 6 may be configured as long as the fastening part 6 may be configured as long as it can selectively fix the first housing 2a and the second housing 2b. For example, the fastening part 6 may be configured as follows. .

As shown in FIGS. 1 and 3, the fastening part 6 protrudes perpendicularly to one end of the first housing 2a and the second housing 2b, respectively, and corresponds to the first bracket 8a. ) And the rack gear 10 penetrating the second bracket 8b, the first bracket 8a or the second bracket 8b, and the rack gear 10 and the first bracket 8a. The second bracket 8b may approach or be spaced apart, and may include a gear part 12 through which the rack gear 10 penetrates.

First, the fastening part 6 is provided with a first bracket 8a and a second bracket 8b. The first bracket 8a is formed at the other side of the housing part 1 where the hinge 2c is formed in the first housing 2a. The second bracket 8b is configured to correspond to the first bracket 8a and is formed at the other side of the portion where the hinge 2c is formed in the second housing 2a.

The rack gear 10 is provided in the first bracket 8a and the second bracket 8b. The rack gear 10 is configured to penetrate the first bracket 8a, the second bracket 8b, and the gear unit 12.

The rack gear 10 may be fixed to one side of the first bracket 8a or the second bracket 8b or the housing part 1. This is because the rack gear 10 is engaged with the pinion gear 22 to be described below so that the first bracket 8a and the second bracket 8b are approached or spaced apart from each other.

However, the rack gear 10 is preferably fixed to the second housing 2b or the second bracket 8b when the gear unit 12 to be described below is attached to the first housing 2a. This is to allow the rack gear 10 and the gear unit 12 to be described below to interlock with each other so that the first bracket 8a and the second bracket 8b are approached or spaced apart from each other.

Of course, when the gear part 12 is attached to the second housing 2b, the rack gear 10 is preferably fixed to the first housing 2a or the first bracket 8a.

In addition, a plurality of rack gears 10 may be formed in the first bracket 8a and the second bracket 8b according to the length of the pipe or the length of the bracket.

In addition, the first fastening holes 14a and the second fastening holes 14b are provided in the first bracket 8a and the second bracket 8b so as to correspond to each other. As shown in FIG. 1, when the first bracket 8a and the second bracket 8b are in close contact, the bolt 16 is connected to the first fastening hole 14a and the second fastening hole 14b. Insertion and fixing nut 18 can prevent the bolt 16 from being detached to maintain the close contact of the bracket. A plurality of first fastening holes 14a and second fastening holes 14b may be formed in the first bracket 8a and the second bracket 8b according to the length of the pipe.

In addition, the rack gear 10 is provided with a gear unit 12. The gear part 12 is engaged with the rack gear 10 to control the rack gear 10 to be movable only in one direction, thereby approaching or separating the first bracket 8a and the second bracket 8b. It serves to fix the position.

As shown in FIGS. 4 and 5, the gear part 12 has a space therein, such that the rack gear 10 has a groove 20 and a body 20 through which both sides of the rack gear 10 pass. And a pinion gear meshed with the rack gear 10 and an inner portion of the body portion 20, and the rack gear 10 for guiding the rack gear 10 to move in a predetermined direction. 24 and a cylindrical flange 26 provided on the outside of the body portion 20 and projecting at right angles to the body portion 20.

The gear part 12 is provided with a body part 20. The body portion 20 is provided with a pinion gear 22, a rack gear 10, a ratchet gear 24 therein, the upper portion of the body portion 20 can be opened to be exposed to the outside. . This is for the operator to easily manipulate the pinion gear 22.

The pinion gear 22 is engaged with the rack gear 10 penetrating both sides and the inside of the body portion 20 through the groove of the body portion 20, so that the first bracket 8a and the second bracket. (8b) may be approached or spaced apart.

The rat gear 24 is engaged with the rack gear 10 and is provided to be separated from the pinion gear 22. The ratchet gear 24 serves to prevent the rack gear 10 from being loosened by interlocking the rack gear 10 to move in a predetermined direction.

In addition, the outer side of the body portion 20 may be further configured with a flange 26 for fixing the gear portion 12 to the outer surface of the housing. The flange 26 allows the gear part 12 to be fixed by penetrating a nut or the like to any one side of the outer surface of the housing. Of course, the position of the gear unit 12 in the housing can be adjusted to the desired position by the operator.

In more detail, when the nut or screw of the flange 26 fastened to the fixing part 28 of the housing part 1 is removed and dismantled, the gear part 12 may be detached and installed at another position. It can be reused.

Hereinafter, the operation of the pipe repair apparatus according to the present invention having the configuration as described above in detail.

When damage occurs to a part of the pipe, the pipe repair device of the present invention is fixed to one side of the pipe in a state as shown in FIG. 2, and then the pipe repair device is moved to the position of the damaged pipe.

And, as shown in Figure 4, the operator adjusts the pinion gear 22 with a tool, to move the rack gear 10, so that the first bracket (8a) and the second bracket (8b) in close contact with each other. . At this time, the first bracket 8a and the second bracket 8b that are tightened are not released due to the rat gear 24.

After the first bracket (8a) and the second bracket (8b) as close as possible to each other, the first housing (2a) and the second by fixing a nut or the like through the respective fastening holes (14a, 14b) The housing 2b is completely fixed to the pipe.

At this time, the packing part 4 of the inner surface of the housing 1 is in close contact with the damaged portion of the pipe so that the fluid flowing along the inside of the pipe does not leak to the outside.
