- the spacer 30 may be formed as one body. Accordingly, no gap appears along the circumference of the spacer 30 . Accordingly, the device can more tightly seal between the spacer 30 and the riser pipe 100 .
- the spacer may have a structure divided into at least two. In this structure, the spacer can be more easily installed in the upright pipe 100 .
- the fixing device 10 of this embodiment may have a structure in which the upright pipe 100 and the spacer 30 are closely and closely fixed by the O-ring 40 made of an elastic material.
- the spacer 30 forms an inclined surface 34 along the upper periphery on the inner surface.
- the inclined surface 34 may be formed to be inclined downward so that the distance to the rising pipe 100 becomes closer toward the lower part.
- the inclined surface 34 may be formed in a straight line from the upper end of the spacer 30 toward the inner surface.
- the inclination angle of the inclined surface 34 with respect to the inner surface of the spacer 30 may be variously modified.
- the O-ring 40 may be positioned on the inclined surface 34 by being inserted into the upright pipe 100 .
- the O-ring 40 is elastically deformed between the inclined surface 34 and the outer circumferential surface of the upright pipe 100 and closely adheres thereto, and by applying a frictional force between the two members, the upright pipe 100 can be fixed.
- the frictional force by the O-ring 40 is applied over the entire outer circumferential surface of the upright pipe 100, even the O-ring 40 with a small diameter can fix the upright pipe 100 with a large overall force.
- the O-ring 40 has a ring-shaped closed curve structure.
- the O-ring 40 may be formed to have a diameter substantially corresponding to the diameter of the upright pipe 100 , and may be installed by being inserted into the upright pipe 100 .
- the O-ring 40 may be formed of a silicon material. Silicone has excellent heat resistance as well as elasticity and adhesion. Since the O-ring 40 is formed of a silicon material, it is possible to tightly fix the upright pipe 100 even at a high temperature.
- the O-ring 40 may be formed of a rubber material having excellent heat resistance in addition to a silicone material.
- the O-ring 40 may be in close contact between the two members while being pressed between the inclined surface 34 of the spacer 30 and the outer peripheral surface of the upright pipe 100 .
- the upright pipe 100 is arranged vertically so that it sags downward by its own load.
- the O-ring 40 fitted to the outer circumferential surface of the rising pipe 100 is subjected to a downward force by the rising pipe 100 drooping downward.
- the O-ring 40 is pressed between the rising pipe 100 and the gradually narrowing inclined surface 34 while moving downward along the inclined surface 34 by the rising pipe 100 .
- force can be applied to the O-ring by pulling the pipe.
- the O-ring 40 is elastically deformed and strongly adheres to the upright pipe 100 and the inclined surface 34 . Accordingly, the upright pipe 100 may be fixed to the spacer 30 without sagging downward by the frictional force of the O-ring 40 strongly adhered to the outer circumferential surface.
- the upright pipe 100 is completely fixed to the fixing device, and can be securely fixed to the fixing device without flowing in the downward direction as well as in the upward direction.
- the inclined surface 34 is organically coupled to the O-ring 40 to act as a one-way stopper that regulates only the downward deflection of the upright pipe 100 .
- the inclined surface 34 allows the riser pipe 100 to move upward from the spacer 30 and does not sag downward.
- the gap between the slope 34 and the rising pipe 100 becomes narrower. Accordingly, while the O-ring 40 is further compressed between the inclined surface 34 and the rising pipe 100 , the O-ring 40 is more strongly in close contact with the inclined surface 34 and the rising pipe 100 by the elastic force. Due to the strong adhesion of the O-ring 40 , the upright pipe 100 is no longer drooping down and is fixed to the spacer 30 . Since the self-weight of the rising pipe 100 is continuously applied to the O-ring 40 , the rising pipe 100 is in close contact with the O-ring 40 to continuously maintain a state fixed to the spacer 30 .

- the space between the inclined surface 34 and the rising pipe 100 is widened, so that the adhesion of the O-ring 40 to the inclined surface 34 and the rising pipe 100 is reduced.
- the riser pipe 100 may be moved upward past the O-ring 40 . Accordingly, it is possible to easily move the rising pipe 100 upward to install the rising pipe 100 in the fixing device.
- the O-ring 40 is elastically deformed between the spacer 30 and the upright pipe 100 , and may be removed by absorbing the shock applied to the upright pipe 100 . Accordingly, even when an external force such as an earthquake is applied, it is possible to minimize damage to the upright pipe 100 by the external force.
- the O-ring 40 is in close contact with the entire outer circumferential surface of the rising pipe 100 , so that it is possible to tightly seal the rising pipe 100 as a whole.
- the O-ring 40 is elastically deformed, and a state in close contact between the rising pipe 100 and the spacer 30 can be maintained continuously. Accordingly, it is possible to more effectively block leakage of gas or the like by preventing the occurrence of a gap between the rising pipe 100 and the spacer 30 .
- the cover 50 is installed at the top of the space to cover the upper portion of the inclined surface 34 . It is possible to prevent the O-ring 40 from being separated above the spacer by the cover 50 .
- a hole 51 may be formed through the center so that the upright pipe 100 is fitted.
- a protrusion 52 may be further formed on the lower surface of the cover 50 to protrude from the inclined surface 34 along the hole 51 to press the O-ring 40 .
- the protrusion 52 may be moved downward of the inclined surface 34 by pushing the O-ring 40 . Accordingly, when the riser pipe 100 is installed, the O-ring 40 may be in contact with the inclined surface 34 and the riser pipe 100 with sufficient pressure to perform the operation. Therefore, slip does not occur between the rising pipe 100 and the O-ring 40, and it is possible to accurately fix the rising pipe to a set height.
- the cover 50 may be detachably installed on the spacer 30 .
- the spacer 30 may be formed with a seating groove 35 in which the cover 50 is placed.
- the seating groove 35 may be formed with a step difference from the upper end of the spacer 30 .
- At least one hook 56 is formed at the bottom of the cover 50 along the periphery, and a plurality of fastening holes 36 through which the hooks 56 are fitted and caught may be formed in the seating groove 35 .
- the cover 50 may be formed as one body.
- the spacer may have a structure divided into at least two. In this structure, the spacer can be more easily installed in the upright pipe.
- the fixing device 10 may be assembled by sequentially inserting the spacer 30 , the O-ring 40 , and the cover 50 to the upright pipe 100 passing through the sleeve 20 . As the spacer 30, the O-ring 40, and the cover 50 are assembled to the sleeve 20, the standing pipe 100 is fixed to the fixing device.
- the rising pipe 100 can be fixed.
- the upright pipe 100 can be freely moved upward in a state in which it is not pressed between the inclined surfaces 34 by the O-ring 40 . Accordingly, during installation, the upright pipe 100 may be inserted into the O-ring 40 and moved upward while passing through the spacer 30 . In a state in which the upright pipe 100 is moved to an appropriate position, it is fixed to the fixing device without sagging downward by the O-ring. Accordingly, it is possible to more easily fix the rising pipe 100 to the fixing device 10 .
