Description

Technical Field

[0001] This utility model belongs to the field of sealed containers, and in particular relates to a guide sealing and venting plug. Background Technology

[0002] In industrial production and daily life, barrels are commonly used to store liquids. When sealing the barrels, a barrel cap with internal threads is used to connect with the external threads of the barrel opening through a screw-on connection. Conventional barrel caps have poor sealing performance, and the liquid stored in the barrel often leaks through the threaded connection between the barrel cap and the barrel opening during transportation or handling. In addition, when commonly used barrel caps are screwed onto the barrel opening, the internal threads of the barrel cap often become misaligned with the threads of the barrel opening due to the barrel cap being crooked, making installation inconvenient. When the barrel contains chemicals or medicines that produce gas, a vent plug is usually installed on the barrel cap to release the gas and prevent the barrel from deforming and breaking due to excessive internal pressure. However, commonly used barrel caps with vent plugs are not securely installed and are prone to falling off. Utility Model Content

[0003] The purpose of this utility model is to provide a guide sealing and venting plug to solve the problems of poor sealing effect of conventionally used caps, frequent leakage of liquid stored in the container during transportation and handling through the threaded connection between the cap and the container opening, and the inconvenience of installation due to misalignment of the cap threads when screwing it onto the container opening. When the container contains chemical substances or medicines that produce gas, a venting plug is usually installed on the cap to release gas and prevent the container from deforming and breaking due to excessive pressure. However, the venting plugs on commonly used container caps are not securely installed and are prone to falling off.

[0004] To achieve the above objectives, the specific technical solution of this utility model for a guide sealing and venting plug is as follows:

[0005] A guide sealing vent plug includes a plug body; the plug body is a circular structure with a W-shaped cross-section; a raised edge is provided on the upper part of the plug body; a connecting buckle is provided on the outer side of the raised edge; a structural ring is provided on the upper side of the middle part of the plug body; multiple supporting ribs are provided on the inner side of the structural ring; and an installation ring is provided on the bottom of the plug body.

[0006] Furthermore, a sealing ring is provided on the downward-facing convex edge.

[0007] Furthermore, the diameter of the upper edge of the outer wall of the plug is larger than the diameter of the lower edge.

[0008] Furthermore, the outer wall of the plug is composed of a first inclined surface on the upper side and a second inclined surface on the lower side; the angle between the first inclined surface and the vertical direction is 8-12°; the angle between the second inclined surface and the vertical direction is 14-18°.

[0009] Furthermore, a limit strip is provided on the inner wall of the mounting ring.

[0010] Furthermore, the bottom edge of the plug is rounded.

[0011] Furthermore, an exhaust hole is provided at the bottom of the plug body relative to the inside of the mounting ring.

[0012] This utility model of a guide-sealing vent plug has the following advantages: The guide-sealing vent plug is connected to the inside of an internally threaded bucket lid via a connecting buckle on the outer side of the plug body's convex edge. It enhances the sealing effect when the lid of a liquid container is screwed on. The convex edge on the upper outer side of the plug body and the sealing ring below it ensure a tight seal. When the lid is screwed on, the convex edge seals the end face of the bucket opening, working in conjunction with the sealing ring to prevent liquid leakage through the threaded connection between the internally threaded lid and the bucket opening. The bottom edge of the plug body is rounded. During lid installation, the rounded edge on the lower side of the plug body, combined with the fact that the diameter of the upper edge of the outer wall of the plug body is larger than the diameter of the lower edge, guides the lid installation, ensuring the lid is installed at the correct angle and preventing misalignment of the lid screw. To prevent misalignment between the threads of the plug and the barrel opening threads, the upper edge diameter of the plug body is set to be larger than the lower edge diameter. When the barrel lid is screwed on and sealed, the outer wall of the plug body gradually increases in diameter from bottom to top, which gradually squeezes against the inner wall of the barrel opening to form a sealing effect, preventing liquid leakage and further enhancing the sealing effect of the barrel lid. The limiting strip set on the inner wall of the mounting ring can effectively prevent the vent plug from falling off after installation. The vent hole set in the position of the plug body in the mounting ring can promptly discharge the high-pressure gas in the barrel to the upper structural ring position of the plug body, and discharge it through the vent groove set in the corresponding position of the barrel lid. The vent hole will not be blocked during the rotation of the barrel lid, which will affect the venting. Multiple support ribs provide good support for the structural ring, reduce the deformation of the structural ring during use, and ensure that the structural ring corresponds with the vent groove of the connected outer cover to prevent affecting the venting effect.

[0018] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed description of a guide sealing and venting plug according to this utility model.

[0019] like Figure 1-3 As shown, this utility model discloses a guide sealing and venting plug, including a plug body 1; the plug body 1 is a circular structure with a W-shaped cross-section; a raised edge 2 is provided on the upper part of the plug body 1 outward; a sealing ring 8 is provided on the raised edge 2 downward, and a connecting buckle 3 is provided on the outer side of the raised edge 2; a structural ring 4 is provided on the upper side of the middle part of the plug body 1; multiple supporting ribs 5 are provided on the inner side of the structural ring 4; and an installation ring 6 is provided on the bottom of the plug body 1.

[0020] Combination Figure 1-3 As shown, in use, the guide sealing vent plug is connected to the inside of the internal threaded bucket lid via the connecting buckle 3 set on the outside of the protrusion 2 of the plug body 1. The bucket lid is aligned with the bucket opening and screwed on. As the bucket lid is rotated downwards, the entire plug body 1, except for the position of the protrusion 2, enters the inside of the bucket opening. After the bucket lid is screwed on and sealed, the protrusion 2 abuts against the end face of the bucket opening to form a seal. Together with the sealing ring 8 set on the lower side of the protrusion 2, a good sealing effect is formed at the bucket opening, preventing the liquid in the bucket from leaking out through the threaded connection between the internal threaded bucket lid and the bucket opening. It is used to increase the sealing effect after the bucket opening of the liquid container is screwed on and sealed, and to prevent the liquid in the bucket from leaking out.

[0021] The bottom edge of the stopper 1 is rounded, and the diameter of the upper edge of the outer wall of the stopper 1 is larger than the diameter of the lower edge. The rounded edge of the bottom edge of the stopper 1, combined with the fact that the diameter of the upper edge of the outer wall of the stopper 1 is larger than the diameter of the lower edge, can guide the installation of the lid, ensuring that the lid is installed at the correct angle and will not be crooked, thus avoiding misalignment of the lid threads and the barrel opening threads due to lid crookedness.

[0022] The outer wall of the stopper 1 is composed of a first inclined surface 10 on the upper side and a second inclined surface 11 on the lower side. The first inclined surface 10 has an angle of 8-12° with the vertical direction; the second inclined surface 11 has an angle of 14-18° with the vertical direction. During the process of installing the bucket lid onto the bucket opening, the second inclined surface 11 with a larger angle with the vertical direction works with the bucket lid to form a guiding effect, making it easier for the bucket opening to slide into the gap between the stopper 1 and the bucket lid. The first inclined surface 10 with a smaller angle with the vertical direction works with the inner wall of the bucket opening to form a tight seal and prevent leakage.

[0023] By setting the upper edge diameter of the outer wall of the plug body 1 to be larger than the lower edge diameter, when the bucket lid is screwed on and sealed, the outer wall of the plug body 1, which gradually increases in diameter from bottom to top, will gradually press against the inner wall of the bucket opening to form a sealing effect, preventing the liquid inside the bucket from leaking out and further increasing the sealing effect of the bucket lid. When this sealing and venting plug is installed at the bucket opening along with the internal thread bucket lid, the outer wall of the plug body 1 fits against the inner wall of the bucket opening to form a seal. When the bucket opening is deformed by force, the outer wall of the plug body 1 will deform accordingly with the bucket opening, ensuring that there is still an effective sealing effect when the bucket opening is deformed by force, and preventing leakage caused by gaps between the plug body 1 and the bucket opening due to bucket opening bumps or squeezing.

[0024] A vent hole 7 is provided at the bottom of the plug body 1 relative to the inside of the mounting ring 6. A limit strip 9 is provided on the inner wall of the mounting ring 6. The limit strip 9 on the inner wall of the mounting ring 6 can effectively prevent the installed vent plug from falling off. Together with the vent hole 7 provided in the mounting ring 6, the high-pressure gas in the barrel can be discharged to the upper structural ring 4 of the plug body 1 in a timely manner. The gas is discharged through the vent groove provided in the corresponding position of the barrel lid. The vent hole 7 will not be blocked during the rotation of the barrel lid, which would affect the venting. Multiple support ribs 5 provide a good support effect for the structural ring 4, reduce the deformation of the structural ring 4 during use, and ensure that the structural ring 4 corresponds to the vent groove of the connected outer cover, so as to prevent affecting the venting effect.
