Description

Technical Field

[0001] The utility model relates to the technical field of sealing riveting, in particular to a pressure riveting rivet and a sealing riveting structure. Background Art

[0002] Pull riveting, press riveting and sealed riveting structures are methods used to connect and reinforce parts. Pull riveting forms a connection by pulling the tail of the rivet, which is suitable for situations where a larger pulling force is required. Press riveting forms a connection by squeezing the tail of the rivet, which is suitable for situations where a smaller squeezing force is required. The sealed riveting structure forms a seal during riveting to prevent liquid or gas leakage.

[0003] After searching, the Chinese patent announcement number is: CN219975070U, which discloses a self-clinching rivet and a sealed riveting structure, including a pin, a flange is provided at one end of the pin, a stop step and a sealing groove are provided on the inner side of the flange, the blind hole in the pin includes a through hole and a threaded hole, one end of the through hole opens to the outer side of the flange, and the other end of the through hole extends to the inner side of the flange to form a deformable area on the pin close to the flange, the self-clinching rivet includes a pin and a screw matched with the threaded hole, the sealed riveting structure includes a sheet metal, a sealing member is provided between the sealing groove and the sheet metal, and the pin passes through the rivet hole and is provided with a deformable area For the convex part formed by deformation, a rivet gun can be used to rivet with rivet rivets, or a compression riveting device can be used to perform compression riveting on multiple compression rivets at one time. A stop step is used to prevent the convex part from squeezing the sheet metal and deforming it, resulting in excessive flatness. The stop step and the convex part are riveted on both sides of the sheet metal respectively, and the seal provides effective sealing. During compression riveting, screws are used to prevent the threaded hole from deforming, meeting the requirements of thread go / no-go gauge detection. However, in actual use, the device is difficult to remove after riveting. When the rivet needs to be removed, the steps are relatively cumbersome, and the rivet will still remain on the surface and cannot be completely removed, thereby reducing the reliability of the device.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Specifically, when fixing the required object, first insert the first nail head 1 into the object, then pull the first threaded rod 4 to deform the first deformation portion 3, so that the first nail head 1 is firmly fixed, and at the same time, rotate the first positioning ring 5 along the first threaded rod 4 so that it and the object clamped by the first nail head 1 are squeezed against each other to fix the rivet.

[0033] Reference Figure 3 and Figure 4 A cross groove 17 is provided on the outer side of the first nail head 1; a plurality of mounting holes 2 are provided on the outer side of the first positioning ring 5, an injection port 18 is provided on the right side of the outer wall of the barrel cover 6, and a plurality of reserved holes 16 are provided on the outer side of the first threaded rod 4; a threaded ring 13 is threadedly connected to the inner side of the second positioning ring 9, and a sealing plate 14 is fixedly connected to the right side of the threaded ring 13;

[0034] Specifically, glue is injected into the barrel cover 6 through the injection port 18, and the glue flows into the first threaded rod 4 through the reserved hole 16. After the glue solidifies, the pull rivet can be sealed. At the same time, the second threaded rod 10 is taken out, the threaded ring 13, the second positioning ring 9 and the second nail head 7 are fixed together, and the self-riveted rivet is sealed with the help of the sealing plate 14. The pull rivet and the self-riveted rivet can be sealed. Specifically, the cross groove 17 allows the first nail head 1 to be operated by tools such as a screwdriver. At the same time, the fixing effect of the rivet can be further improved by installing a threaded part inside the mounting hole 2.

[0035] Reference Figure 2 , Figure 3 and Figure 4 The right side of the second nail head 7 is fixedly connected with the second deformation portion 8, the inner side of the second nail head 7 is threadedly connected with the second threaded rod 10, and the outer side of the second threaded rod 10 is threadedly connected with the second positioning ring 9;

[0036] Specifically, when fixing the required object, first insert the second threaded rod 10 therein so that the second positioning ring 9 on its outer side abuts against the object, and then, by pressing the second nail head 7, the second deformation portion 8 is deformed to tightly connect it to the object to be fixed. When disassembly is required, the rivet can be removed by simply removing the second threaded rod 10 from the inner side of the second nail head 7, and during the entire disassembly process, the rivet will not remain or cause additional damage to the object.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A handle 12 is fixedly connected to the outer side of the second nail head 7; an expansion portion 15 is fixedly connected to the outer side of the second deformation portion 8; a positioning column 11 is provided on the inner side of the second nail head 7, and the positioning column 11 is engaged with the second threaded rod 10;

[0038] Specifically, the handle 12 can facilitate the recovery and storage of the pull rivets, the engagement of the positioning column 11 with the second threaded rod 10 can improve the stability of the second threaded rod 10 during connection, and the expansion portion 15 can improve the deformation effect of the second deformation portion 8, so that the fixation of the second nail head 7 is more secure.

[0039] Working principle: Before using the device, first, after fixing the required object, insert the first nail head 1 and pull the first threaded rod 4 to deform the first deformation part 3, thereby ensuring that the first nail head 1 is firmly fixed. At the same time, rotate the first positioning ring 5 along the first threaded rod 4 to squeeze it and the object clamped by the first nail head 1 against each other to fix the rivet. This step can not only improve the firmness of the riveting, but also reduce the time and force required for the riveting operation, thereby improving the convenience. In addition, insert the second threaded rod 10 into the object to be fixed so that the second positioning ring 9 on its outer side is against the object. Then, press the second nail head 7 to deform the second deformation part 8, thereby tightly fixing it to the required object. When disassembly is required, the rivet can be removed smoothly by simply taking out the second threaded rod 10 from the inner side of the second nail head 7. In the entire disassembly process, the rivet will not remain or cause additional damage to the object, thereby improving the reliability of the device. By injecting glue into the injection port 18 in the barrel cover 6 and allowing the glue to flow into the first threaded rod 4 through the reserved hole 16, the pull-riveted rivet can be sealed after the glue solidifies. At the same time, by taking out the second threaded rod 10, the threaded ring 13, the second positioning ring 9 and the second nail head 7 are fixed together, and the compression-riveted rivet is sealed by the sealing plate 14, which effectively prevents the rivet from being corroded by moisture, air, chemicals, etc., thereby improving the service life of the device.
