[0027] See also Figures 1 to 4As shown, this embodiment provides a fastener with a sealing function, which includes a screw body 1 and a sealing member 2, wherein the first section of the screw body 1 is provided with a receiving hole 11, and the second section of the screw body 1 is provided with a first threaded hole 12, wherein the first threaded hole 12 is configured to be connected to a connecting member, and at least a portion of the sealing member 2 is arranged in the receiving hole 11, and the sealing member 2 includes a first sealing portion 21 and a second sealing portion 22, wherein the first sealing portion 21 is configured to seal the connecting member, and the second sealing portion 22 is sleeved on the first sealing portion 21, and a storage space 23 is provided inside the second sealing portion 22, and the storage space 23 is provided with a seal 24, and the storage space 23 is configured to store a sealing liquid, and the sealing liquid is used to liquid-seal the abutting portion between the first sealing portion 21 and the connecting member.

[0028] It can be seen that by fixing a part of the first sealing part 21 in the accommodating hole 11, the first sealing part 21 can be prevented from being displaced when abutting the connecting piece, thereby ensuring the sealing stability of the first seal, and the abutting position of the first sealing part 21 and the connecting piece is liquid-sealed by the second sealing part 22, thereby solving the problem of air leakage and odor leakage of the fastener, and having the effect of improving the sealing of the fastener.

[0029] As an embodiment, the first end of the first sealing portion 21 is fixedly installed in the accommodating hole 11, the second sealing portion 22 is sleeved on the first sealing portion 21, and the first end of the second sealing portion 22 is fixedly connected to the screw body 1, and the second end of the first sealing portion 21 is higher than the second end of the second sealing portion 22.

[0030] It can be seen that the second sealing part 22 is set outside the first sealing part 21, so that when the first sealing part 21 is subjected to force and abuts against the connecting piece and deforms, the second sealing part 22 is squeezed, so that the sealing film at the water outlet falls off, and the sealing liquid flows out to seal the first sealing part 21 and the connecting piece. It is simple to use and has the effect of being easy to use.

[0031] As an embodiment, a second threaded hole 25 is formed on the first sealing portion 21 , and the second threaded hole 25 has the same thread shape, nominal diameter, number of threads, pitch and rotation direction as the first threaded hole 12 , and is located on the same axis.

[0032] It can be seen that the second threaded hole 25 is provided on the first sealing part 21, so that the deformation of the first sealing part 21 can be increased when it rotates to abut the connecting piece, so as to promote the sealing film to fall off from the water outlet, which has the advantage of improving work efficiency.

[0033] As an implementation manner, the seal 24 includes a water outlet and a sealing film, wherein the sealing film is disposed on the water outlet, and the sealing film is configured to seal the sealing liquid in the storage space.

[0034] It can be seen that the water outlet is sealed by the sealing film, the sealing method is simple, and when the second sealing part 22 is deformed, the sealing liquid breaks through the sealing film and flows out of the water outlet, thereby liquid-sealing the abutment part of the first sealing part 21 and the connector, thereby improving the sealing efficiency.

[0035] As an implementation manner, the water outlet is arranged on one side of the second end of the second sealing portion 22 .

[0036] Specifically, the water outlet is arranged on one side of the second section, which is convenient for the sealing liquid to flow out, and has the advantage of improving the sealing efficiency.

[0037] As an implementation manner, the bottom of the receiving hole 11 is provided with a chamfer.

[0038] It can be seen that after the first sealing part 21 abuts against the connecting piece, the chamfer can increase the deformation of the bottom of the first sealing part 21, increase the squeezing of the second sealing part 22, and facilitate the sealing liquid to break through the sealing film, which has the advantage of improving the sealing efficiency.

[0039] As an implementation manner, the sealing liquid is any one of water or oil.

[0040] It can be seen that the sealing liquid has a simple composition and a low manufacturing cost.

[0041] The specific working principle of the above-mentioned fastener with sealing function is as follows:

[0042] The first sealing part 21 is connected to the connecting piece through the first threaded hole 12 and the second threaded hole 25. The second end of the first sealing part 21 abuts the connecting piece. During the rotational connection, the first sealing part 21 is deformed by force, and an extrusion force is generated on the second sealing part 22. The sealing liquid breaks through the sealing film by force and flows out from the water outlet, thereby liquid-sealing the abutting part between the first sealing part 21 and the connecting piece.

[0043] In the embodiments disclosed in the present invention, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "connect" can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the embodiments disclosed in the present invention can be understood according to specific circumstances.

[0044] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
