Description

Pipe support device

[0001] The present disclosure relates to a device for supporting a pipe.

[0002] Piping systems are commonly used for fluid transport across industries, including machinery, electronics, food, chemical, and pharmaceutical industries. Piping systems include support devices that support pipes transporting fluids such as liquids and gases against building ceilings.

[0003] The pipe support device may include two semicircular housings that surround the outer surface of the pipe and bolts that fasten and secure the semicircular housings. A suspension rod extending from a support surface, such as a ceiling of a building, may be further provided to position the pipe support device at a specific location. The pipe support device is connected to the suspension rod so as to support the pipe at a specific location from the support surface. The pipe support device can support the pipe by surrounding the pipe with the two semicircular housings and tightening the bolts.

[0004] A liner may be further provided on the inner surface of the semicircular housing of the pipe support device to prevent damage caused by friction between the liner and the pipe. The liner has a semicircular structure and is installed on the inner surface of the housing, forming the inner surface that contacts the pipe.

[0005] Pipes are laid at an angle to ensure smooth flow and avoid fluid pooling. Pipe supports must accommodate and stably support the inclined pipe. Pipe supports are adjusted to varying heights along the pipe to accommodate the pipe's incline. However, the pipe's incline can cause stress in the pipe, placing pressure on the housing of the pipe support that holds it in place.

[0006] Accordingly, a technology is being developed to minimize stress generation by tilting the pipe support device according to the slope of the pipe.

[0007] Previous U.S. Patent Publication No. 2005-0205722 (Title: Pipe and tube support) discloses a structure having a means for angling a housing relative to a suspension rod so as to accommodate an inclined pipe or tube.

[0008] However, the above-mentioned conventional device has a structure that uses a suspension rod with an end processed into an arc shape and a female screw hole formed on the inside, and thus has a problem in that it is difficult to use a computer bolt that is generally installed on a ceiling, etc.

[0009] Accordingly, separate work is required to install a suspension rod on a supporting surface such as the ceiling or to process the tip of an already installed computer bolt.

[0010] Additionally, mounting the device to a suspension rod requires bolts to be fastened to the suspension rod through the inner surface of the housing. This makes bolting difficult and inconvenient, and the complex internal structure of the housing for bolt fastening makes manufacturing difficult.

[0011] This project is to provide a pipe support device that can be simply installed and used on suspension rods such as conventional, universally used and already installed computer bolts.

[0012] The present invention provides a pipe support device that facilitates fastening work to a suspension rod.

[0013] The present invention provides a pipe support device that enables a simpler housing structure of the device.

[0014] A pipe support device of the present embodiment may include a housing portion that surrounds the pipe, including a first housing having a semicircular structure, and a second housing having a semicircular structure and being rotatably connected to the first housing via a hinge axis; a fastening portion for fastening and fixing the first housing and the second housing; and a connecting portion that connects the housing portion to a suspension rod and allows rotation and tilting of the housing portion with respect to the suspension rod.

[0015] The first housing and the second housing may further include a liner that is detachably installed in each of the first and second housings and forms a cylindrical inner surface that comes into contact with the pipe.

[0016] A fixing member may be further included to increase the fixing force of the liner to the housing member.

[0017] The above-mentioned fastening portion may include an end portion extending from the ends of the first housing and the second housing, a bolt rotatably coupled to the end of the second housing, a slot formed at the end of the end of the first housing into which the bolt is inserted, and a nut fastened to the bolt to tighten the two ends.

[0018] The above liner may include a body portion formed in a semicircular shape with a smooth inner surface in contact with the pipe and a smooth outer surface in contact with the inner surface of the housing portion, and ribs formed to protrude toward the outer surface on each of two sides of the body portion and fitted into the side surfaces of the housing portion.

[0019] The above-mentioned fixed portion may have a structure in which a protrusion is formed laterally on both sides of the housing portion and extends along the side, and a groove formed on the inner surface of the rib of the liner and interlocked with the protrusion, such that the groove is fitted into the protrusion and coupled.

[0020] The above-mentioned fixed portion may be formed to be inclined downward so that the yoke is gradually spaced farther from the side of the housing portion as it goes from the outside to the inside, and the protrusion may be formed to be inclined upward so that it gradually protrudes outward as it goes from the outside to the inside against the yoke.

[0021] The above-mentioned fixed portion may be formed to be inclined downward so that the yoke is gradually spaced farther from the side surface of the housing portion as it moves inward from the outside, and the protrusion may be formed to be a projection that protrudes laterally from the side surface of the housing portion toward the inner end and is inserted into the spaced-off space of the yoke.

[0022] The above liner may be made of PTFE material.

[0023] The above connecting portion may include a protruding rod portion integrally formed with the second housing and having a female screw hole formed at an outer end thereof, a cylindrical shape, a groove portion having a through hole formed at the center at the end facing the protruding rod portion, a plug at the opposite end that is fastened and fixed to the suspension rod, and a connecting bolt having a dome-shaped head fitted into the through hole of the groove portion and in contact with the groove portion and screwed into the female screw hole of the protruding rod portion to connect the plug and the protruding rod portion, and the dome-shaped head of the connecting bolt may be structured to move with respect to the groove portion to allow the housing to form an angle with respect to the suspension rod.

[0024] An O-ring may further be included that is installed between the facing ends of the protruding rod portion and the groove portion.

[0025] The above protruding rod portion may have a structure in which a step portion for accommodating the O-ring is formed along the outer circumference of the tip.

[0026] The above home portion may be a structure that forms a concave portion along the outer circumference of the tip where the O-ring is seated.

[0027] The above protruding rod portion may have a dome shape that is convexly curved toward the groove portion, the groove portion may have a concave groove shape that is opposite to the protruding rod portion, and the protruding rod portion and the groove portion may have a spaced-apart structure.

[0028] The above plug has a female thread formed on the inner surface of the tip, and can be screwed and connected to a male thread formed on the tip of the suspension rod.

[0029] The inner diameter of the above plug may be structured to be relatively larger than the diameter of the dome-shaped head of the above connecting bolt.

[0030] The above-mentioned home portion may have a dome shape that is convexly curved toward the protruding rod portion, and the protruding rod portion may have a structure that has a concave groove shape facing the home portion.

[0031] The above connecting bolt includes a cylindrical body that extends from a dome-shaped head and fits into a through hole of the groove, a screw portion that extends from the cylindrical body and is fastened to a female screw hole of the protruding rod portion, and the cylindrical body may have a structure that is smaller than the diameter of the through hole of the groove and is capable of moving at a predetermined angle.

[0032] The cylindrical body of the above connecting bolt may be formed with a structure having a length such that, when the tip is completely fastened to the female screw hole so that it contacts the tip of the protruding rod portion, a gap is formed between the tip of the protruding rod portion and the groove portion.

[0033] According to this implementation example, the device can be installed and used on suspension rods, such as conventional, universally used computer bolts. This allows for the use of existing suspension rods, making it practical and reducing the time and effort required to install new suspension rods.

[0034] Installation is completed by simply attaching the device, which has been prepared with bolts installed, to the suspension rod, eliminating the need for bolts to be attached through the inside of the housing, making the work easier.

[0035] In addition, since there is no need to form holes or the like inside the housing for bolt fastening, the structure of the housing can be simplified and manufactured more easily, and durability can be improved by preventing a decrease in rigidity.

[0044] Hereinafter, embodiments of the present invention will be described in detail. However, these are presented as examples and are not intended to limit the present invention. The present invention is defined solely by the scope of the claims set forth below. The embodiments described below may be modified in various ways without departing from the spirit and scope of the present invention. Wherever possible, identical or similar parts are represented by the same reference numerals in the drawings.

[0045] The terminology used below is for the purpose of describing specific embodiments only and is not intended to limit the present invention. As used herein, the singular forms "a," "an," and "the" include plural forms as well, unless the context clearly dictates otherwise. The word "comprising," as used herein, specifies a particular feature, region, integer, step, operation, element, and / or component, but does not exclude the presence or addition of other specific features, regions, integers, steps, operations, elements, components, and / or groups.

[0046] In the description of this embodiment, expressions such as top, bottom, front, back, first, second, one side, other side, etc. indicate relative positions, directions, or orders, and their technical meanings are not bound by dictionary meanings.

[0047] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. However, the following examples are only preferred embodiments of the present invention, and the present invention is not limited to the following examples.

[0048] Figures 1 to 4 illustrate a pipe support device according to the present embodiment.

[0049] For the convenience of the following description, a suspension rod (100) extends upward from the ground as shown in FIG. 2, and a pipe support device (10) is installed at the top of the suspension rod (100) as an example. Of course, unlike FIG. 2, a pipe support device may be installed at the bottom of a suspension rod that is installed on a ceiling or the like and extends downward. The suspension rod (100) is attached to a support surface such as the ground or ceiling and is interconnected with the pipe support device (10). The length of the suspension rod (100) may be changed according to the pipe position.

[0050] In Fig. 3, the x-axis direction, which is the direction in which the pipe (P) passes, is called the axial direction or lateral direction, and the surface facing the x-axis direction is called the side surface. The center of the support device (10), i.e., the center of the pipe (P), is called the inner side or inner surface, and the opposite side is called the outer side or outer surface.

[0051] As illustrated, the pipe support device (10) of the present embodiment may include a housing portion (20) that surrounds the pipe (P), a fastening portion for fastening and fixing the first housing (22) and the second housing (24) that form the housing portion (20), and a connecting portion (40) that connects the housing portion (20) to a suspension rod (100) and allows rotation and tilting of the housing portion with respect to the suspension rod (100).

[0052] The housing portion (20) is composed of a first housing (22) and a second housing, which surround the pipe (P) and are detachably connected. Hereinafter, the housing portion (20) may refer to both the first housing (22) and the second housing.

[0053] The first housing (22) and the second housing (24) are connected so that one end can rotate around the hinge axis (26), and are opened and closed by rotating around the hinge axis (26).

[0054] The first housing (22) and the second housing (24) form a semicircular structure. Accordingly, the first housing (22) and the second housing (24) can be rotated around the hinge axis (26) to close or opened.

[0055] A fastening part is provided on the free end opposite to the tip where the hinge axis (26) of the first housing (22) and the second housing (24) are installed. The fastening part fastens and secures the first housing (22) and the second housing (24).

[0056] The fastening part may include an end portion (28) that extends from the ends of the first housing (22) and the second housing (24), a bolt (30) that is rotatably coupled to the end of the second housing (22), a slot (31) formed at the end of the end portion (28) of the first housing (24) and into which the bolt (30) is inserted, and a nut (32) that is fastened to the bolt (30) and tightens the two ends (28).

[0057] Accordingly, when the bolt (30) is rotated and inserted into the slot (31) of the first housing (24) and the nut (32) is tightened, the end (28) of the first housing (22) and the end (28) of the second housing (24) are fastened and fixed by being tightened by the nut (32).

[0058] The fastening member may be modified in various ways other than the structure described above. For example, the fastening member may have a structure in which a through hole and a screw-fastening hole are formed at each of the two ends, and a bolt is passed through the through hole and screwed into the screw-fastening hole, thereby tightening and fixing the ends together.

[0059] The housing portion (20) may be provided with a connecting portion (40) for connection with the suspension rod (100). In the present embodiment, the connecting portion (40) may have a structure that connects the housing portion (20) to the suspension rod (100) so that it can rotate and tilt. The specific structure of the connecting portion (40) will be described later.

[0060] The housing portion (20) may further include a liner (50) that provides a surface that comes into contact with the pipe (P). The liner (50) of the present embodiment is detachably installed in each of the first housing (22) and the second housing (24) to form a cylindrical inner surface that comes into contact with the pipe (P). The liners (50) form a pair and are installed in each of the first housing (22) and the second housing (24). Since the two liners (50) have the same structure, hereinafter, the term "liner (50)" may refer to both liners (50).

[0061] The liner (50) can be manufactured, for example, by injection molding a plastic material.

[0062] In this embodiment, the liner (50) may be made of polytetrafluoroethylene (PTFE) material.

[0063] The liner (50) of the present embodiment may include a body portion (52) formed in a semicircular shape with a smooth inner surface in contact with the pipe (P) and a smooth outer surface in contact with the inner surface of the housing portion (20), and ribs (54) formed to protrude toward the outer surface on each side of the body portion (52) and fitted into the side surface of the housing portion (20).

[0064] The liner (50) is fitted and connected to the housing portion (20) via ribs (54) formed on both lateral sides of the body portion (52). The gap between the ribs (54) on both sides of the liner (50) may be formed to have a size that roughly corresponds to the gap between the both sides of the housing portion (20). The corresponding size may mean that the gap between the ribs (54) is equal to or slightly smaller than the gap between the both sides of the housing portion (20). Accordingly, the ribs (54) of the liner (50) can be forcibly fitted and connected to both sides of the housing portion (20) to be installed in close contact. Accordingly, when the ribs (54) of the liner (50) are fitted and tightly connected to both sides of the housing portion (20), the liner (50) does not easily come off from the housing portion (20) due to frictional force.

[0065] In this way, by simplifying the structure of the liner (50) to a structure in which the liner (50) is fitted and joined to the side of the housing portion (20) by the rib (54), it is possible to manufacture a liner (50) with enhanced fixing strength to the housing portion (20) using PTFE material.

[0066] In the conventional case, in order to increase the fixing force between the housing part (20) and the liner (50), a complex structure of protrusions had to be formed on the outer surface of the liner (50), and in this case, it was difficult to mold the liner (50) with PTFE material. Accordingly, in the case of the liner (50) manufactured with the conventional PTFE material, it was difficult to establish a fixing structure with the housing part (20), and the liner (50) was easily separated from the housing part (20).

[0067] The liner (50) of this embodiment has a simple structure as described above, so that it can be easily manufactured with PTFE material, and the liner (50) can be more firmly fixed to the housing portion (20) by the rib (54).

[0068] The support device (10) of the present embodiment may further include a fixing member to increase the fixing force of the liner (50) to the housing portion (20). The fixing member is provided between the liner (50) and the housing portion (20) to removably fix the liner (50) to the housing portion (20).

[0069] Fig. 5 illustrates a fixing structure between a liner (50) and a housing portion (20) according to the present embodiment. As illustrated in Fig. 5, the fixing portion may include a protrusion (62) that protrudes laterally on both sides of the housing portion (20) and extends along the side, and a recess (60) formed on the inner surface of a rib (54) of the liner (50) to engage with the protrusion (62), such that the recess (60) is fitted into and coupled to the protrusion (62). Accordingly, the protrusion (62) on the side surface of the housing portion (20) and the recess (60) on the inner surface of the rib (54) are engaged with each other to engage with each other, so that the liner (50) can be firmly fixed without being detached from the housing portion (20).

[0070] The protrusion (62) is formed to protrude laterally based on the line (L) formed by the side surface of the housing portion (20). The yoke (60) is formed by being dug into the inner surface of the rib (54) based on the line (L) formed by the side surface of the housing portion (20).

[0071] In this embodiment, the yoke (60) is formed by being slanted downward so that it gradually moves away from the side of the housing portion (20) from the outside to the inside. Conversely, the protrusion (62) is formed by being slanted upward so that it gradually protrudes outward from the outside to the inside, facing the yoke (60).

[0072] That is, based on the line (L) formed by the side surface of the housing portion (20) in FIG. 5, a protrusion (62) having a triangular cross-section shape inclined at a predetermined angle (R) is formed on the side surface of the housing portion (20), and a recess (60) having a triangular cross-section shape inclined at a predetermined angle (R) is formed on the inner surface of the rib (54) of the liner (50).

[0073] Accordingly, when the yoke (60) is engaged with the protrusion (62), the yoke (60) is caught on the protrusion (62) and does not come off. Accordingly, the liner (50) is firmly fixed to the housing (20), and can be prevented from coming off from the housing (20).

[0074] In addition, the liner (50) can be simply installed in the housing part (20) by moving the liner (50) from the front end of the housing part (20) while aligning the yoke (60) and the protrusion (62).

[0075] In addition to the above-described structure, the protrusion may be a structure in which a projection is formed to protrude laterally from a position tilted toward the inner end of the side surface of the housing portion and is inserted into a spaced space of the rib. Accordingly, the protrusion on the side surface of the housing portion and the rib on the inner surface of the rib are interlocked and combined with each other, so that the liner can be firmly fixed without being detached from the housing portion.

[0076] Figures 6 and 7 illustrate the structure of a connecting portion according to the present embodiment.

[0077] As shown, the connecting portion (40) connects the housing portion (20) and the suspension rod (100), and is structured to allow rotation and tilting of the housing portion (20) with respect to the suspension rod (100).

[0078] To this end, the connecting portion (40) of the present embodiment may include a protruding rod portion (70) integrally formed with the second housing (24) and having a female screw hole (72) formed at the outer end (71), a cylindrical shape, a groove portion (82) having a through hole (84) formed at the center at the end facing the protruding rod portion (70), and a plug (80) whose opposite end is fastened and fixed to a suspension rod (100), and a connecting bolt (90) having a dome-shaped head (92) fitted into the through hole (84) of the groove portion (82) and in contact with the groove portion (82), and screwed into the female screw hole (72) of the protruding rod portion (70) to connect the plug (80) and the protruding rod portion (70).

[0079] Accordingly, as the dome-shaped head (92) of the connecting bolt (90) moves relative to the groove (82) of the plug (80), the housing in which the connecting bolt (90) is installed can be tilted at a predetermined angle relative to the suspension rod (100) in which the plug (80) is installed.

[0080] In addition, the support device (10) of the present embodiment can be easily installed on a suspension rod (100) via a plug (80), thereby reducing the effort required to mount a dome-shaped connecting bolt (90) on the suspension rod (100), and improving workability.

[0081] An O-ring (75) may be further installed between the facing ends of the protruding rod portion (70) and the groove portion (82). The O-ring (75) may be made of an elastic material such as rubber or silicone. The O-ring (75) allows relative movement of the protruding rod portion (70) with respect to the plug (80), and is installed so as to be elastically pressed between the protruding rod portion (70) and the groove portion (82) to prevent the housing portion (20) from rattling with respect to the plug (80).

[0082] The protruding rod portion (70) can form a step portion (76) that accommodates an O-ring (75) along the outer periphery of the tip (71). The groove portion (82) can also form a recess (86) along the outer periphery of the tip where the O-ring (75) is seated.

[0083] Accordingly, the O-ring (75) can be precisely seated between the protruding rod portion (70)'s protruding portion (76) and the groove portion (86) of the groove portion (82) to tightly seal the two members. In addition, even if the gap between the protruding rod portion (70) and the groove portion (82) changes due to tilting of the support device (10), the position of the O-ring (75) can be stably maintained.

[0084] The protruding rod portion (70) can be formed integrally with the second housing (24). A female screw hole (72) for fastening a connecting bolt (90) is formed at the center of the tip (71) of the protruding rod portion (70). Since the female screw hole (72) is formed on the outside of the protruding rod portion (70), the connecting bolt (90) can be mounted on the outside of the housing portion (20) regardless of the inside of the housing portion (20).

[0085] The plug (80) may be formed in a cylindrical shape with an outer diameter that corresponds approximately to the outer diameter of the protruding rod portion (70) or the outer diameter of the suspension rod (100).

[0086] One end of the plug (80) facing the protruding rod portion (70) forms a groove portion (82). A through hole (84) is formed in the center of the groove portion (82) so that a connecting bolt (90) can pass through it. Accordingly, the connecting bolt (90) can be inserted into the inside of the plug (80) and screwed into the female screw hole (72) of the protruding rod portion (70) through the through hole (84). As the dome-shaped head (92) of the connecting bolt (90) is caught in the through hole (84), the plug (80) can be connected to the end of the protruding rod portion (70) via the connecting bolt (90).

[0087] A gap is formed between the groove (82) and the tip (71) of the protruding rod portion (70). Accordingly, the tip (71) of the protruding rod portion (70) of the housing portion (20) can move and float by the gap distance formed with respect to the groove (82) of the plug (80). Accordingly, the housing portion (20) in which the protruding rod portion (70) is formed can move and tilt with respect to the plug (80) installed on the suspension rod (100).

[0088] The gap between the home portion (82) and the protruding rod portion (70) can be maintained by a connecting bolt (90).

[0089] In this embodiment, the protruding rod portion (70) may have a structure in which the protruding rod portion (70) has a dome shape that is convex outward toward the groove portion (82), and the groove portion (82) has a structure in which the groove portion (82) has a concave groove shape that is concave inward so as to face the protruding rod portion (70). Accordingly, when the protruding rod portion (70) moves with respect to the plug (80), the tilting angle can be increased while the interference between the groove portion (82) and the tip (71) is minimized.

[0090] The inner diameter of the plug (80) is larger than the diameter of the dome-shaped head (92) of the connecting bolt (90), so that the dome-shaped head (92) of the connecting bolt (90) can move smoothly inside the plug (80) when the housing part (20) is tilted.

[0091] The plug (80) can be installed by being screwed onto the suspension rod (100). In this embodiment, the plug (80) has a structure in which a female screw (88) is formed on the inner surface of the tip, and can be screwed onto and connected to a male screw (102) formed on the tip of the suspension rod (100).

[0092] Accordingly, the support device (10) of the present embodiment can be easily installed by connecting it to a universal suspension rod (100) having a screw (102) formed thereon through a plug (80).

[0093] A flat fitting groove (81) may be further formed on the outer surface of the plug (80) so that a tool such as a wrench can be engaged for screw connection with the suspension rod (100). Thus, by using the flat fitting groove (81), the plug (80) can be more easily rotated to be connected to and disconnected from the suspension rod (100).

[0094] The connecting bolt (90) may include a cylindrical body (94) that extends from the dome-shaped head (92) and fits into the through hole (84) of the groove (82), and a screw portion (96) that extends from the cylindrical body (94) and is fastened to the female screw hole (72) of the protruding rod portion (70).

[0095] The dome-shaped head (92) may have a structure in which the portion that comes into contact with the inner surface of the groove (82) of the plug (80) is curved in an arc shape. Accordingly, when the support device (10) is tilted, the dome-shaped head (92) of the connecting bolt (90) and the inner surface of the through hole (84) of the groove (82) of the plug (80) can move relatively smoothly with each other.

[0096] In this embodiment, the cylindrical body (94) is structured to be smaller than the diameter of the through hole (84) of the groove (82). Accordingly, the cylindrical body (94) of the connecting bolt (90) can flow smoothly inside the groove (82) of the plug (80).

[0097] The cylindrical body (94) forms a step with the screw portion (96), and when the screw portion (96) is fastened to the female screw hole (72), the tip (95) of the cylindrical body (94) comes into contact with the protruding rod portion (70), thereby limiting the distance between the protruding rod portion (70) and the groove portion (82). The tilting angle of the support device (10) can be varied depending on the length of the cylindrical body (94).

[0098] The cylindrical body (94) of the above connecting bolt (90) is formed with a length that sufficiently separates the tip (71) of the protruding rod portion (70) and the groove portion (82) when the tip (95) is completely fastened to the female screw hole (72) so that the tip (71) of the protruding rod portion (70) is in contact with the tip (71).

[0099] The length of the cylindrical body (94) of the connecting bolt (90) can be varied along the axial direction according to the set tilting angle of the support device (10).

[0100] Accordingly, as shown in Fig. 7, when the plug (80) is fastened and fixed to the suspension rod (100), the housing portion (20) can tilt according to the slope of the pipe (P) installed in the housing portion (20) as the dome-shaped head (92) of the connecting bolt (90) screwed to the protruding rod portion (70) and the tip groove (82) of the plug (80) move.

[0101] At this time, the dome-shaped head (92) of the connecting bolt (90) is fixed by being screwed to the protruding rod portion (70) of the housing portion (20) and moves together with the housing portion (20). Accordingly, the inner surface of the groove portion (82) of the plug (80) moves relatively along the arc-shaped dome-shaped head (92), and the housing portion (20) tilts with respect to the suspension rod (100) on which the plug (80) is installed.

[0102] In this way, the support device of this embodiment is provided with a plug (80), so that a tilting action is performed between the connecting bolt (90) and the plug (80). Therefore, the suspension rod (100) is substantially unrelated to the tilting action of the support device (10), so that the device can be simply installed on a suspension rod (100) that is conventionally used for general purposes and used as a tilting structure.

[0103] In addition, since the connecting bolt (90) is fastened and prepared in advance on the outside of the housing portion (20), the support device (10) of the present embodiment can be easily installed on the suspension rod (100) using the plug (80).

[0104] Meanwhile, Fig. 8 illustrates another embodiment of a connecting portion.

[0105] The connecting portion (40) of the present embodiment below has the same structure as that described in the above embodiment except for the structure of the tip (73) and the groove (83) of the protruding rod portion (70). Accordingly, the same drawing numbers are given to the same configurations as those of the above embodiment, and a detailed description thereof is omitted.

[0106] As shown in Fig. 8, the connecting portion (40) of the present embodiment may have a structure in which the groove portion (83) is in a dome shape that is convexly bent toward the protruding rod portion (70), and the tip (73) of the protruding rod portion (70) is in a concave groove shape so as to face the groove portion (83).

[0107] The O-ring (75) can be installed by being seated in the step portion (76) formed in the outer periphery of the tip (73) of the protruding rod portion (70) and in contact with the groove portion (83) of the plug (80). In the case of this structure, a recess for O-ring seating is not necessarily formed in the outer periphery of the tip of the groove portion (83). The O-ring (75) seals between the plug (80) and the protruding rod portion (70) and can be elastically pressed between the two members to maintain the housing portion (20) in a tilted state with respect to the plug (80).

[0108] The diameter of the through hole (84) formed in the groove (83) of the plug (80) is formed to be larger than the cylindrical body (94) of the connecting bolt (90), so that the connecting bolt (90) can move relative to the plug (80).

[0109] The inner surface of the groove (83) of the plug (80) is formed to be curved in an arc shape to face the curved dome shape of the dome-shaped head (92) of the connecting bolt (90). That is, the groove (83) of the plug (80) is inserted between the dome-shaped head (92) curved in an arc shape and the tip (73) of the protruding rod portion (70) formed in a concave groove shape opposite thereto, so that the dome-shaped head (92) can move in an arc shape along the groove (83) of the plug (80). Accordingly, the housing portion (20) in which the connecting bolt (90) is installed can be tilted in an incline with respect to the plug (80).

[0110] Accordingly, as shown in Fig. 8, when the plug (80) is fastened and fixed to the suspension rod (100), the dome-shaped head (92) of the connecting bolt (90) screwed to the protruding rod portion (70) and the tip groove (83) of the plug (80) move according to the inclination of the pipe installed in the housing portion (20), and the housing portion (20) tilts according to the inclination of the pipe.

[0111] At this time, the dome-shaped head (92) of the connecting bolt (90) is fixed by being screwed to the protruding rod portion (70) of the housing portion (20) and moves together with the housing portion (20). Accordingly, the inner surface of the groove portion (83) of the plug (80) moves relatively along the arc-shaped dome-shaped head (92), and the housing portion (20) tilts with respect to the suspension rod (100) on which the plug (80) is installed.

[0112] In this embodiment, the groove (83) of the plug (80) can be smoothly moved along between the dome-shaped head (92) of the connecting bolt (90) which is also formed in the same dome shape and the concave groove-shaped tip (73) of the protruding rod portion (70).

[0113] In this way, in the case of the present embodiment, since the tip of the protruding rod portion (70) forms a concave groove shape facing the dome-shaped head (92) of the connecting bolt (90), the groove portion (83) of the plug (80) can move more smoothly between the dome-shaped head (92) and the tip (73) of the protruding rod portion (70), thereby enabling tilting.

[0114] In addition, the connecting portion (40) according to the embodiment of Fig. 8 also has a structure in which a plug (80) is connected to a protruding rod portion (70) via a connecting bolt (90), so that the supporting device can be simply installed and used on a conventional suspension rod (100).

[0115] While exemplary embodiments of the present invention have been illustrated and described above, various modifications and alternative embodiments will be apparent to those skilled in the art. All such modifications and alternative embodiments are contemplated and encompassed by the appended claims, and are intended to remain within the true spirit and scope of the present invention.
