Description

Technical Field

[0001] The utility model relates to the technical field related to plugs, in particular to a waterproof plug with a new structure. Background Art

[0002] The plug is also called a pipe cap, a cover, a pipe cover, etc. It is used to connect to the end of the pipe to block the unnecessary openings and play a sealing role.

[0003] A conventional plug can only meet the needs of sealing the pipe orifices of one specification of pipes, and cannot meet the needs of sealing the pipe orifices of pipes of multiple specifications. It is not very practical. Therefore, how to design a plug that can meet the needs of sealing the pipe orifices of two or more pipes and improve the practicality of the plug has become a technical problem that needs to be solved urgently.

[0007] By adopting the above technical scheme, a pipe with an external thread can be threadedly connected through the first thread set on the inner wall of the first annular body, and another pipe with an external thread can be threadedly connected through the second thread set on the inner wall of the second annular body. By setting a first annular sealing ring at the bottom of the first annular groove and a circular sealing gasket in the second annular body, when the pipes are connected, they can abut against the first annular sealing ring or the circular sealing gasket to achieve a sealed connection. Compared with the existing plugs that generally only meet the requirements of sealing the pipe orifices of one specification of pipes, the waterproof plug with this new structure can achieve the sealing of two specifications of pipes, thereby improving the practicability of the plug.

[0008] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0009] In some embodiments, the outer wall of the second annular body is provided with a third thread. The third thread provided on the outer wall of the second annular body can be threadedly connected to a pipe with an internal thread, thereby increasing the need for plugging a pipe of a different specification and further improving the practicality of the plug.

[0010] In some embodiments, the screwing head is a hexagonal screw head structure.

[0011] In some embodiments, the screwing head is a cylindrical structure with a hexagonal groove on the right side.

[0012] In some embodiments, a third annular body is provided on the right side of the screwing head, the inner diameter of the third annular body is smaller than the inner diameter of the first annular body and larger than the outer diameter of the second annular body, and the inner side wall of the third annular body is provided with a fourth thread. The fourth thread provided on the inner side wall of the third annular body can be threadedly connected to a pipe with an external thread, thereby increasing the need for plugging a pipe of one more specification, further improving the practicality of the plug.

[0013] In some embodiments, a cylinder located in the third annular body is provided on the right side of the screwing head, the diameter of the cylinder is smaller than the inner diameter of the second annular body, a gap is maintained between the cylinder and the third annular body to form a second annular groove, a fifth thread is provided on the outer side of the cylinder, and a second annular sealing ring is provided at the bottom of the second annular groove. The fifth thread on the cylinder can be threadedly connected to a pipe with an internal thread, thereby increasing the need for plugging a pipe of one more specification, further improving the practicality of the plug.

[0014] In some embodiments, a centerline of the first annular body is collinear with a centerline of the second annular body.

[0015] In some embodiments, a centerline of the cylindrical body is colinear with a centerline of the third annular body. BRIEF DESCRIPTION OF THE DRAWINGS
