Description

Watertight Belt {A WATERPROOF BELT}

The present invention relates to a watertight belt, and more particularly, to a flat belt plate surrounding the outer circumferential surface of the tube, a plurality of bands formed in close contact with the outer surface of the belt plate, and to close and close the seam of the tube. Consists of fastening means for interconnecting both ends of the binding band through the belt plate, it can be completely watertight while simply joining two interconnecting pipes, and close the joints with watertight belts even after installation of two neighboring pipes. This is possible to provide a watertight belt which can significantly improve workability.

Various pipes such as double walled polyethylene sewage pipes, triple composite pipes, glass fiber composite pipes, fume pipes, steel pipes, drainage pipes, drainage pipes, agricultural water pipes, intake pipes, etc. These tubes are used to connect the tubes made in a certain length in the longitudinal direction, or have a predetermined angle with respect to the longitudinal direction.

In particular, the most important thing in connecting the pipes is that the connection parts of the pipes should be joined to have perfect watertightness so that fluids inside the pipes do not leak, and more preferably, the pipes may be subjected to a certain crustal change or temperature change. The watertightness is maintained even when shrinking.

However, if the watertightness of the pipes buried underground is not perfect, fluids may leak from the joints and contaminate the geological and groundwater, and thus adversely affect the environment. Therefore, various connection structures have been proposed to maintain the watertightness of these pipes. .

Among them, a general watertight belt, as shown in Figure 1, when the two pipes 30 are connected to each other by a bolt and a nut to the end of the socket 20 to the band 10 installed at the contact portion of each pipe do.

Therefore, the pressure applied to the band is transmitted by tightening the socket 20 so that the outer circumferential surface of the tube is in close contact with the inner circumferential surface of the band, thereby preventing the material passing through the inside of the tube from leaking through the joint of the tube.

However, such a watertight belt is difficult for the socket to bend when the socket presses the band and closely adheres to the tube, and it is difficult to tighten the band with a slight pressure, and the pressure applied to the band by the socket is partially uneven, which causes the socket or the band to become uneven. There arises a problem that the efficiency of watertightness is significantly reduced, such as deformation occurs.

An object of the present invention for improving this is to make the connection work of the pipe very quickly and accurately when connecting the neighboring pipe, and to improve the watertightness by tightly fixing the joint between the pipe and the pipe.

In addition, the present invention is to provide a water-tight belt to close the joint portion of the tube by a ratchet to increase the contact area with the outer peripheral surface of the tube, to increase the resilience of the plate to make a more intimate contact.

In another embodiment, as shown in FIG. 5A or 5B, the coupling part 340 is a gear 312 of the ratchet 311 protruding into the protrusion groove 341 formed in the tightening connection part 330. The detent 360 having a predetermined inclined surface to fix and release) may be connected to the elastic hinge through the ball spring 370.

The detent 360 is in contact with the cog wheels 312 of the ratchet 311 and the fixing piece having a predetermined inclined surface, and the extension is formed on the fixing piece is released to be installed by the carbon spring (370) Pieces 362 are formed at one end and the other end, respectively, and when the release piece 362 is pushed while the gear 312 of the ratchet is fixed by the fixing piece 361, the ball spring is compressed and the fixed piece ( 361 is separated from the ratchet 311 is installed so that the binding band 200, which was wound on the rotary part 310 is released.

Referring to the operation of the present invention made of such a configuration as follows.

First, remove the cloth with a rag to prevent foreign matter or volatile substances such as dirt and dust from interfering with the joint between the pipe and the joint. At this time, it is preferable to heat the center portion of the heat shrink sheet with a torch to prevent bubbles from forming in the heat shrink sheet.

After the heat shrink sheet is cooled, the watertight belt of the present invention is wound. First, the belt plate on which the binding band is fixed is wound on the upper surface on which the heat shrink sheet is wound, and then the rotating part installed to be rotatable by pulling the binding band. Inserted into the fitting groove of, the square groove is inserted into the square groove formed on the upper portion of the rotating portion when the binding band is wound on the rotating portion and the belt plate is tightening the tube.

According to another embodiment, first, the coupling ring of the binding band is fastened as a fixing bolt and a nut through the coupling ring of the coupling part, wherein the outer circumferential surface of the tube on which the heat shrink sheet is wound and the inner circumferential surface of the watertight belt are spaced a predetermined distance from each other. When spaced apart, and tightening the watertight belt fastening means to reduce this separation distance watertight belt is in close contact with the tube to be watertight.

That is, while rotating the rotary part of the coupling portion connected as a bolt and a nut to the connecting ring, and after inserting the square hair into the saga groove formed at the end of the rotating portion and rotates the square hair, as shown in Figure 6 The band is wound to tighten the tube.

Here, the outer diameter of the rotating part is provided with a ratchet that prevents the reverse rotation of the cog wheels, and once rotated, it is stopped in the state rotated by the lever, and the binding band is also rotated by the rotation of the cylindrical rotating part.

As such, when the joint of the pipe is tightened, the belt plate can press the heat shrink sheet wound inside thereof, thereby tightly sealing the joint.

In another embodiment, when the detent portion is pushed to the engaging portion by the elastic spring by elastic hinge, pushing the release piece of the tooth detent fixed to the latch, the compression spring of the detent detent is compressed from the latch The binding band, which was separated and wound around the rotating part, is released, and finally the belt plate that surrounds the joint of the pipe can be released together.

As described above, the present invention can be made tightly by first connecting the two pipes to prevent the seam to be watertight, or even tightly wound watertight belt around the tube even if cracks or microgrooves are generated in the existing pipe. There is an advantage to this.

In addition, the present invention is to tighten the seams between the tubes by the ratchet to prevent the reverse rotation of the teeth and the two pipes are closely connected by the tensile force, so that the fluid or gas leaks into the gap between the parts where the two pipes abut or foreign matter from the outside Inflow can be prevented.

While the invention has been shown and described with respect to specific embodiments thereof, it will be appreciated that the invention can be variously modified and varied without departing from the spirit or scope of the invention as provided by the following claims. do.

Thus, according to the present invention, it is possible to simply connect the pipes of similar or identical diameters and connect them, so that not only can be easily performed in the field, but also the work of connecting the pipes is made very quickly and accurately, thereby significantly improving workability. There is an advantage to this.

The present invention is to seal the joint portion of the tube by the ratchet tightly to increase the contact area with the outer peripheral surface of the connecting tube, and to allow the emergency watertight at the time of cracking or damage of the tube as well as the joint of the tube and the relationship to the installation place There is an advantage without it.
