[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figure 1 - Figure 2 As an embodiment provided by the present utility model: A riveting structure of an iron shell with a sealing structure includes a first shell plate 1, which is a partial plate surface at the riveting part of the iron shell plate. A second shell plate 2 is arranged below the first shell plate 1, which is a partial plate surface riveted to the iron shell. A riveting mechanism is commonly arranged between the first shell plate 1 and the second shell plate 2 for riveting the iron shell. The riveting mechanism includes a rivet 3 and a sealing member 4. The sealing member 4 is fixedly connected to the outside of the rivet 3. The sealing member 4 is made of rubber as a whole. Both the rivet 3 and the sealing member 4 are of an integral structure. The rivet 3 is made of metal.
[0031] As Figure 3 - Figure 4As shown, the seal 4 includes two sealing rings 42. After being squeezed, they can deform to improve the sealing performance at the riveting joint, making the riveting joint not easily corroded. The upper sealing ring 42 is located below the limiting ring 31. A connecting ring 41 is fixedly connected between the two sealing rings 42 for connecting the two sealing rings 42. The bottom of the lower sealing ring 42 is fixedly connected with a sealing sleeve 43, which is used to protect the sealing performance of the connection between the blind rivet 3, the first shell plate 1, and the second shell plate 2. The seal 4 also includes a squeezing sleeve 44, which is slightly larger than the first connection port 11 and the second connection port 21. It is in a hollow ring shape and can deform when being squeezed. The squeezing sleeve 44 is fixedly connected with the sealing sleeve 43. The bottom of the squeezing sleeve 44 is fixedly connected with a fixing ring 45, which is used to tighten the lower part of the squeezing sleeve 44 to improve the connection sealing performance between the seal 4 and the blind rivet 3.
[0032] Further, the blind rivet 3 includes a limiting ring 31, which is used for limiting the riveting mechanism. The bottom of the limiting ring 31 is fixedly connected with a first deformation ring 32, which will deform when being squeezed. The lower part of the first deformation ring 32 is fixedly connected with a first threaded sleeve 33, which can be threadedly connected with the riveting head of the riveting equipment. The bottom of the first threaded sleeve 33 is fixedly connected with a second deformation ring 34, which can deform when an upward pulling force is applied to the second threaded sleeve 35, so as to cooperate with the limiting ring 31 to completely fix the riveting mechanism, the first shell plate 1, and the second shell plate 2. The bottom of the second deformation ring 34 is fixedly connected with a second threaded sleeve 35, which can be threadedly fixed with the riveting head of the riveting equipment. The inner walls of the first threaded sleeve 33 and the second threaded sleeve 35 are both provided with threads and the thread directions are the same, which is convenient for the connection of the riveting head of the riveting equipment.
[0033] Furthermore, a sealing groove 12 is opened at the top of the first shell plate 1, which is used to cooperate with the connection and sealing of the connecting ring 41 and the two sealing rings 42. A first connection port 11 is opened at the bottom of the sealing groove 12, and its size is adapted to the sealing sleeve 43. A second connection port 21 is opened in the middle of the second shell plate 2, which is communicated with the first connection port 11 and its size is adapted to the sealing sleeve 43.
[0034] Working principle: When in use, the riveting mechanism is passed through the No. 1 connection port 11 and the No. 2 connection port 21 on the No. 1 shell plate 1 and the No. 2 shell plate 2. When the extrusion sleeve 44 at the bottom of the seal 4 passes through the No. 1 connection port 11 and the No. 2 connection port 21, it will be squeezed and deformed to assist it to pass through the No. 1 connection port 11 and the No. 2 connection port 21. After the opening 21 reaches the bottom of the No. 2 shell plate 2, it will be restored and stuck in the lower part of the No. 2 connecting opening 21. At this time, the sealing ring 42 at the bottom will contact the bottom of the sealing groove 12, and then the limiting ring 31 will be pressed by the riveting equipment. When the limiting ring 31 is subjected to pressure, the first deforming ring 32 at its lower part will be deformed due to the pressure. At the same time, the limiting ring 31 will be pressed against the top of the No. 1 shell plate 1. At this time, the connecting ring 41 will be stretched open by the deformed first deforming ring 32, and the upper and lower sealing rings will be tightened. The sealing ring 42 will be squeezed by the first deforming ring 32 and the limiting ring 31, and deformed, thereby sealing the upper and lower parts of the sealing groove 12 to improve the sealing between the rivet 3 and the No. 1 shell plate 1. Then, the rivet head on the riveting device is fixed with the first threaded sleeve 33 and the second threaded sleeve 35, and then pulled upward. At this time, since the limiting ring 31 of the rivet 3 and the first deforming ring 32 have been fixed with the No. 1 shell plate 1, when pulled upward, the position of the second threaded sleeve 35 is It will change and generate an upward squeezing force on the second deforming ring 34. At this time, the second deforming ring 34 will be deformed and generate an upward squeezing force on the extrusion sleeve 44. At this time, the extrusion sleeve 44 will be deformed to seal the connection between the rivet 3 and the second shell plate 2. At the same time, the deformed second deforming ring 34 will press and fix the extrusion sleeve 44. At this time, the riveting between the riveting mechanism and the No. 1 shell plate 1 and the No. 2 shell plate 2 can be completed, and the rivet head can be taken out from the rivet 3.
