Description

[Technical Field]

[0001] The present invention relates to a waterproof ring that can waterproof a fastening portion of a bolt or screw. [Background technology]

[0002] Fastening using fasteners such as bolts and screws is a widely used method for fastening objects. By inserting a metal washer between the head of the bolt or other fastener and the object to be fastened, the fastening force of the bolt or other fastener can be evenly distributed around the bolt's insertion hole in the object to be fastened. This provides benefits such as protecting the base material and preventing the bolt from loosening. However, because washers do not provide waterproofing around the bolt's insertion hole, it has been necessary to apply caulking such as silicone to the insertion hole and its surrounding area to prevent water from seeping into the object through the insertion hole. Therefore, when there are a large number of fastening points, the time required for the caulking process can be a problem. In this context, Patent Document 1 discloses a waterproof washer in which a rubber bushing is fitted into the washer body, so that when the bolt is tightened, the tightening force of the bolt is applied to the bushing via the bolt head and the washer body, causing the bushing to deform on the surface of the object to be fixed, thereby sealing the bolt insertion hole.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-200345 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the waterproof washer disclosed in Patent Document 1 may not provide an adequate seal and may not perform its waterproof function if, for example, the bolt is not tightened properly, or the bolt insertion hole is tilted relative to the surface of the object to be fixed, causing the waterproof washer to tilt and the bush to deform distorted.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a waterproof ring that can easily and reliably waterproof a fastening point such as a bolt. [Means for solving the problem]

[0006] In order to achieve the above object, the invention described in claim 1 is a waterproof ring comprising a ring body and a lid portion, wherein the ring body has a bottom surface and a cylindrical outer wall formed along the outer edge of the ring body, and is a hollow cylindrical shape that opens upward, a body through-hole having a diameter smaller than that of the ring body is formed in the center of the bottom surface, a cylindrical inner wall having a height lower than that of the outer wall is formed around the periphery of the body through-hole, and a predetermined number of outflow holes extending to the bottom surface are formed in the inner wall, and the lid portion is a member that closes the open upper part of the ring body ... outer wall A waterproof ring having a circular shape when viewed from above, with an outer diameter equal to the inner diameter, a lid through-hole of the same size as the main body through-hole formed in the center of the lid, and an annular rim protruding downward on the underside of the lid so as to contact the outer periphery of the inner wall when the lid is attached to the ring body from above to close the opening of the ring body, and when the opening of the ring body is closed with the lid, the space formed between the ring body and the lid becomes a filling space, which is filled with gel-like caulking material and the volume of this filling space changes as the lid slides up and down. The invention described in claim 2 is characterized in that, in addition to the above configuration, a predetermined number of locking portions are formed on the inside of the outer wall of the ring body, and the same number of lockable portions as the locking portions are formed on the outer periphery of the lid portion, and when the lid portion is attached to the ring body, the lockable portions lock onto the locking portions. [Effects of the Invention]

[0007] According to the invention of claim 1, when fixing an object to be fixed, by inserting a waterproof ring instead of a washer, when a bolt or the like is screwed into the object to be fixed, the head of the bolt or the like presses the lid part, and as the volume of the filled space decreases, the caulking material filled in the filled space flows out from the outflow hole, and the outflowing caulking material can caulk the gap between the bolt or the like and the threaded hole of the bolt or the like provided in the object to be fixed, as well as the gap between the object to be fixed and the waterproof ring, making it easy to provide reliable waterproofing to the fastened parts of the bolt or the like. In addition, the caulking work can be done simultaneously in the time required for the fastening work, thereby shortening the work time. According to the invention of claim 2, in addition to the above-mentioned effects, the lid portion does not easily come off the ring body, making it easier to handle the waterproof ring.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is an explanatory view showing a waterproof ring of the present invention, (a) is a perspective view, (b) is an exploded perspective view, and Fig. 2 is an explanatory view showing a central vertical cross section of the waterproof ring of the present invention. The waterproof ring 1 includes a ring body 2 and a lid portion 3, as shown in FIG.

[0010] As shown in FIG. 1(b), the ring body 2 has a hollow cylindrical shape that is open upward and includes a bottom surface 4 and a cylindrical outer wall 5 formed along the outer edge of the ring body 2. A body through-hole 6 of a predetermined diameter is formed in the center of the bottom surface 4, through which a fixing means such as a bolt can be inserted. A cylindrical inner wall 7 of a lower height than the outer wall 5 is formed along the periphery of the body through-hole 6. A predetermined number of outlet holes 8 are formed in the inner wall 7, each extending to the bottom surface 4. Furthermore, a predetermined number of recesses 9 are formed on the inner surface of the outer wall 5 as locking portions.

[0011] The lid 3 is a member that closes the open top of the ring body 2, and is circular in top view with a diameter equal to the inner diameter of the outer wall 5 of the ring body 2. A lid through-hole 10 having a diameter equal to the body through-hole 6 is formed in the center of the lid 3. On the outer periphery of the lid 3, protrusions 11 are formed as engaging portions at positions corresponding to the recesses 9 formed on the ring body 2, and the same number of protrusions 11 as the recesses 9. On the underside of the lid 3, as shown in FIG. 2, a circular rim 12 that protrudes downward is formed. The rim 12 is formed so as to contact the outer periphery of the inner wall 7 when the ring body 2 and the lid 3 are assembled.

[0012] The waterproof ring 1 is formed by attaching a lid 3 to a ring body 2 from the opening side (above) of the ring body 2 so as to close the open top of the ring body 2. At this time, the space formed between the ring body 2 and the lid 3 becomes a filling space 13, and as shown in Figure 2, a gel-like caulking material 14 is filled into the filling space 13. The lid 3 is also slidable in the up and down direction relative to the ring body 2, and the volume of the filling space 13 changes as the lid 3 slides. Furthermore, when the waterproof ring 1 is assembled, the protrusions 11 are inserted into the recesses 9 and locked together, preventing the lid 3 from easily falling off the ring body 2, making the waterproof ring 1 easy to handle.

[0013] Fig. 3(a) is an explanatory diagram showing an example of use of the waterproof ring of the present invention, and Fig. 3(b) is an enlarged view showing the area within the circle A in Fig. 3(a). Fig. 4 is a central vertical cross-sectional view of the fastening part when the waterproof ring of the present invention is in use, Fig. 4(a) is before the caulking material flows out, and Fig. 4(b) is after the caulking material flows out. As shown in Figures 3(a) and (B), the waterproof ring 1 is inserted between the object to be fixed W and the bolt 15 at the fastening portion when fixing the object to be fixed W. Here, an example is shown in which the object to be fixed W is attached to a wall surface perpendicular to the ground. At this time, the thread portion 16 of the bolt 15 is inserted through the body through-hole 6 and the lid through-hole 10. When using the waterproof ring 1 to fix the object to be fixed W, it is necessary to select a bolt 15 whose head 17 is larger than the diameters of the body through-hole 6 and the lid through-hole 10, but smaller than the diameter of the lid 3. The object to be fixed W is fixed by screwing the threaded portion 16 of the bolt 15 into a screw hole 18 provided in an anchor 19 installed on the object to be fixed W as shown in Figures 4(a) and (b). Note that if the screw hole 18 can be drilled directly in the installation location of the object to be fixed W, the anchor 19 does not need to be used.

[0014] At this time, as shown in Figure 4(b), as the bolt 15 is tightened, an external force is applied to the lid portion 3 via the head 17 of the bolt 15, and the lid portion 3 is pressed into the ring body 2. As the lid portion 3 is pressed in, the volume of the filled space 13 decreases, and the caulking material 14 filled in the filled space 13 flows out of the filled space 13 through each outflow hole 8. As a result, the caulking material 14 that flows out from the outflow holes 8 flows into the gap between the bolt 15 and the screw hole 18 and the gap between the fixed object W and the waterproof ring 1, thereby caulking these gaps. Therefore, reliable waterproofing can be easily performed on the fastening parts such as the bolt 15.

[0015] The waterproof ring 1 of the above embodiment comprises a ring body 2 and a lid portion 3, the ring body 2 has a bottom surface 4 and a cylindrical outer wall 5 formed along the outer edge of the ring body 2, and is a hollow cylindrical shape that opens upward, a body through-hole 6 having a diameter smaller than that of the ring body 2 is formed in the center of the bottom surface 4, a cylindrical inner wall 7 having a height lower than that of the outer wall 5 is formed around the periphery of the body through-hole 6, and a predetermined number of outflow holes 8 extending to the bottom surface 4 are formed in the inner wall 7, and the lid portion 3 is a member that closes the open upper part of the ring body 2, and has a diameter equal to the inner diameter of the outer wall 5. It has a circular shape when viewed from above and has an outer diameter, and a lid portion through-hole 10 of the same size as the main body through-hole 6 is formed in the center of the lid portion 3, and a circular rim 12 is formed on the underside of the lid portion 3 that protrudes downward so as to contact the outer periphery of the inner wall 7 when the lid portion 3 is attached to the ring main body 2 from above so as to close the opening of the ring main body 2, and when the opening of the ring main body 2 is closed with the lid portion 3, the space formed between the ring main body 2 and the lid portion 3 becomes a filling space 13, and a gel-like caulking material 14 is filled into the filling space 13, and the volume of the filling space 13 changes as the lid portion 3 slides up and down. With the waterproof ring 1 configured in this way, when fixing an object W, the waterproof ring 1 is inserted instead of a washer, and when the bolt 15 is screwed into the object W, the head 17 of the bolt 15 pushes the lid 3, and as the volume of the filling space 13 decreases, the caulking material 14 filled in the filling space 13 flows out from the outflow hole 8, and the outflowing caulking material 14 can caulk the gap between the bolt 15 and the threaded hole 18 provided in the object W, and the gap between the object W and the waterproof ring 1, making it easy to provide reliable waterproofing to the fastened part of the bolt 15. In addition, the caulking work can be done simultaneously in the time required for the fastening work, thereby shortening the work time.

[0016] In addition, a predetermined number of recesses 9 are formed on the inside of the outer wall 5 of the ring body 2, and the same number of protrusions 11 as the recesses 9 are formed on the outer periphery of the lid portion 3 at positions corresponding to the recesses 9, and when the lid portion 3 is attached to the ring body 2, the protrusions 11 are inserted into the recesses 9 and engage with each other. Therefore, the cover portion 3 does not come off the ring body 2, and the waterproof ring 1 becomes easy to handle.

[0017] The present invention has been described above based on the illustrated examples, and the technical scope of the present invention is not limited to these. For example, the material that constitutes the waterproof ring may be metal or resin. Furthermore, the design of the height of the outer and inner walls of the ring body, the diameter of the lid portion, the thickness and shape of the rim, etc. is not limited as long as the filling space can be filled with an amount of caulking material that enables reliable waterproofing of the fastening portion. Furthermore, the shape, number and size of the outflow holes can be set arbitrarily as long as they allow the desired outflow of the caulking material and retain the caulking material within the filling space before the bolts are screwed in. Any caulking material can be selected as long as it is a gel-like material that can be used as a caulking material. Furthermore, the number and shape of the locking portions and locked portions can be set arbitrarily as long as the ring body and the lid portion are not easily separated, and it is also possible to form a convex portion on the ring body and a concave portion on the lid portion, for example.
