The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.

The utility model provides a rivet nut sealed lid, includes lid 1, lid 1 includes first lid 11 and second lid 12, the one end of first lid 11 is provided with top cap 111, the inner wall of the other end of first lid 11 outwards extends and forms second lid 12, and second lid 12 is provided with opening 121.

The scheme provides a rivet nut sealing cover, as shown in fig. 1-2, the rivet nut sealing cover passes through the opening 121 cover of the cover body 1 is arranged on the rivet nut 2, the inside of the rivet nut 2 is provided with a through hole 21, the through hole 21 is communicated with the top end and the bottom end of the rivet nut 2, the top cover 111 of the cover body 1 supports against the top end of the rivet nut 2, the sealing performance of the rivet nut 2 and the inside of the outer container 3 of a product is ensured, and the situation that the cyclopentane foaming material inside the outer container 3 of the product flows into the rivet nut 2 is prevented, so that the thread inside the rivet nut 2 cannot be used. Specifically, as shown in fig. 4, the cover body 1 is sleeved on the top end of the rivet nut 2, and in the process that the bolt 4 is screwed into the rivet nut 2, the rivet nut sealing cover is jacked upwards along with the screwing of the bolt 4, so that the rivet nut sealing cover can be suitable for bolts with different lengths. Since the inner wall of the other end of the first cover 11 extends outward to form the second cover 12, and the second cover 12 is provided with the opening 121, the rivet nut sealing cover has a bell-mouthed structure, which facilitates the quick installation of the rivet nut sealing cover.

Preferably, the cross-sectional area of the second cover 12 is greater than or equal to the cross-sectional area of the first cover 11. Specifically, as shown in fig. 2, the largest cross-sectional area of the second cover 12 is the area of the opening 121, and the smallest cross-sectional area of the second cover 12 is the cross-sectional area of the plane where the connection portion between the second cover 12 and the first cover 11 is located, because the inner wall of the other end of the first cover 11 extends outwards to form the second cover 12, in fact, the second cover 12 is in a horn shape, the cross-sectional area of the second cover 12 is greater than or equal to the cross-sectional area of the first cover 11, the first cover 11 covers the rivet nut 2, and the second cover 12 has a guiding function, so that the rivet nut sealing cover can be conveniently mounted on the rivet nut 2.

Preferably, the cover body 1 is made of PVC. Specifically, because lid 1 is the lid of PVC material, the dampproofing and waterproofing performance of PVC material is good, can effectively prevent that the cyclopentane foaming material from being right the soaking of lid 1, life is longer. In addition, the cover body made of the PVC material is low in production cost.

Another aspect of the present application provides a sealing structure, which includes the cover body 1, the rivet nut 2, and the reinforcing block 5; the cover body 1 is sleeved on the top end of the rivet nut 2, and the reinforcing block 5 is fixed on the outer surface of the rivet nut 2.

According to the scheme, the sealing structure using the rivet nut sealing cover is provided, as shown in fig. 1-2, the rivet nut 2 is installed inside the product outer box 3, and when the cover body 1 is sleeved on the rivet nut 2, the top cover 111 abuts against the top end of the rivet nut 2, so that cyclopentane foaming materials inside the product outer box 3 can be prevented from flowing into the rivet nut 2 through the through hole 21; because the reinforcing block 5 is fixed on the outer surface of the rivet nut 2, the rivet nut 2 is more firmly installed in the product outer box 3 by the reinforcing block, and the rivet nut 2 is not easy to fall off.

Preferably, an included angle α is formed between the inner wall of the second cover body 12 and the outer wall of the rivet nut 2, and the included angle α is 8-20 °.

Specifically, as shown in fig. 2, since the inner wall of the second cover 12 forms an included angle α with the outer wall of the rivet nut 2, the included angle α in one embodiment is 20 °, which is more beneficial to enable the rivet nut sealing cover to be quickly mounted on the rivet nut 2.

Preferably, the cover body length L of the cover body 1 is less than or equal to the height H of the rivet nut 2. Specifically, as shown in fig. 1-2, since the length L of the cover body 1 is less than or equal to the height H of the rivet nut 2, the rivet nut sealing cover can be smoothly sleeved on the rivet nut 2.

Preferably, the outer surface of the bottom end of the rivet nut 2 is provided with a first step 22, the first step 22 is annular, and the top end of the first step 22 is inclined outwards to the bottom end thereof. Specifically, as shown in fig. 3, since the top end of the first step 22 is inclined outward from the bottom end thereof, the rivet nut 2 can be effectively clamped on the outer wall of the product outer box 3, so that the rivet nut 2 can be stably fixed in the product outer box 3.

Preferably, the outer surface of the bottom end of the rivet nut 2 is further provided with a second step 23, the second step 23 is annular, and the second step 23 is located above the first step 22. Specifically, as shown in fig. 3, since the second step 23 is located above the first step 22, a gap is created between the second step 23 and the second step 42, so that the reinforcing block 5 is fixed inside the gap.

Preferably, the cross section of the reinforcing block 5 is L-shaped, the reinforcing block 5 includes a first reinforcing portion 51 and a second reinforcing portion 52, one end of the first reinforcing portion 51 is fixed to the outer surface of the bottom end of the rivet nut 2, one end of the first reinforcing portion 51 is disposed between the first step 22 and the second step 23, and the other end of the first reinforcing portion 51 is connected to one end of the second reinforcing portion 52.

Specifically, as shown in fig. 1 and 3, since the cross section of the reinforcing block 5 is L-shaped, the stability of the L-shaped structure is strong, which is beneficial to reinforcing the rivet nut 2. Because the one end of first reinforcing part 51 is fixed in rivet nut 2's bottom surface, just the one end of first reinforcing part 51 is equipped with first step 22 with between the second step 23, make first step 22 with the second step 23 can block the outer wall of boss 5 and product outer container 3, further fixed rivet nut 2.

The technical principle of the present invention has been described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention.
