[0001] The utility model relates to a riveted part, in particular to a sealed pressure riveted bushing. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] The self-riveted bushing is a riveted structure connected to the mounting plate, generally set in a ring shape. After riveting, the hollow bushing structure can be tightly combined with the mounting plate to expand the structural function of the mounting plate.

[0004] After existing self-riveted bushings are riveted to mounting plates, they typically remain connected to the mounting plate for a single connection. This process inevitably creates gaps due to uneven forces, which can lead to inadequate sealing between the front and rear mounting plates at the riveted joint. Furthermore, to meet these requirements, existing technologies require specific sealing and anti-permeation design within the riveted structure, which increases costs and provides limited effectiveness.

[0005] It should be noted that the above technical background is merely for the purpose of providing a clear and complete description of the technical solutions of the present invention and to facilitate understanding by those skilled in the art. It should not be assumed that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present invention. Utility Model Content

[0006] The purpose of the utility model is to provide a sealing riveted bushing, which can improve the sealing performance by arranging a melting groove between the riveted part and the body and providing a glue coating process at the melting groove.

[0007] In order to achieve the above-mentioned object, the present invention discloses the following sealing riveted bushing, which is used to be connected to a mounting plate, wherein the mounting plate has a mounting hole; the sealing riveted bushing comprises:

[0008] A body, the body being configured as a ring extending in the axial direction, the body having a first surface and a second surface oppositely disposed in the axial direction;

[0009] a riveting portion connected to the first surface of the body, the outer diameter of the riveting portion being smaller than the outer diameter of the body, so that the riveting portion and the body form an annular step-like structure, and the riveting portion is turned outward from the first surface of the body along the axial direction, and the maximum outer diameter of the riveting portion is smaller than the inner diameter of the mounting hole; the riveting portion is configured to be further turned outward during the riveting process, so that at least a portion of the mounting plate is squeezed and deformed by the riveting portion during the riveting process;

[0010] Wherein, a melting groove is provided at the connection point between the outer wall of the riveted portion and the first surface of the main body and is recessed inwardly along the axial direction. The melting groove is used to accommodate at least a portion of the mounting plate after deformation, and the surface of the melting groove is provided with glue.

[0011] Furthermore, after riveting is completed, the dimension of the riveted portion along the axial direction is the same as the dimension of the mounting plate along the axial direction.

[0012] Furthermore, the main body and the riveted portion are configured as an integrally formed structure, and a smooth transition is provided between the inner annular wall of the main body and the inner annular wall of the riveted portion.

[0013] Furthermore, the glue coating at least covers a portion of the mounting plate that is deformed after riveting is completed, so that the connection between the mounting plate and the sealing riveted bushing is completely sealed.

[0014] Furthermore, the glue is set to be epoxy resin glue or polyurethane glue.

[0015] Also disclosed is a connection structure, which includes the above-mentioned mounting plate and sealing riveted bushing, wherein the mounting plate and the sealing riveted bushing are riveted together, and the connection between the mounting plate and the sealing riveted bushing is sealed by means of the glue.

[0016] Also disclosed is a riveting device for riveting the above-mentioned mounting plate and the sealing riveted bushing, wherein the riveting device includes an upper mold corresponding to one side of the riveted part and a lower mold corresponding to one side of the main body, wherein the upper mold has a raised riveting mechanism facing the side of the riveted part, and the riveting mechanism is used to squeeze the riveted part after the upper mold is pressed down so that the riveted part is further turned outward.

[0018] By means of the above technical solution, the beneficial effects of the present invention are as follows:

[0019] The sealing riveted bushing of the utility model can be achieved by providing a melt groove between the riveted part and the main body, and providing a glue treatment at the melt groove. During the riveting process of the sealing riveted bushing, the riveted part is further turned outward, and at least part of the mounting plate is squeezed into the melt groove. Since there is glue treatment in the melt groove, the glue can occupy the gap between the entire riveted structure to achieve a close combination between the sealing riveted bushing and the mounting plate, and the sealing degree is further improved, thereby achieving the sealing installation requirements of the product.

[0030] See Figure 1-3 , is a sealing riveted bushing of this embodiment, used to connect with the mounting plate 100, wherein the mounting plate 100 has a mounting hole; wherein the sealing riveted bushing includes:

[0031] The body 1 is arranged in a ring shape extending in the axial direction, and has a first surface and a second surface arranged opposite to each other in the axial direction;

[0032] The flip riveting portion 2 is connected to the first surface of the main body 1. The outer diameter of the flip riveting portion 2 is smaller than the outer diameter of the main body 1, so that the flip riveting portion 2 and the main body 1 form an annular step-like structure. The flip riveting portion 2 is axially turned outward from the first surface of the main body 1. The maximum outer diameter of the flip riveting portion 2 is smaller than the inner diameter of the mounting hole. The flip riveting portion 2 is configured to further turn outward during the riveting process, so that at least a portion of the mounting plate 100 is squeezed and deformed by the flip riveting portion 2 during the riveting process.

[0033] The outer wall of the riveted portion 2 is connected to the first surface of the main body 1 with a melting groove 3 that is axially recessed inward. The melting groove 3 is used to accommodate at least part of the mounting plate 100 after deformation. The surface of the melting groove 3 is provided with glue 4.

[0034] Regarding the above-mentioned sealing riveted bushing structure, it is mainly composed of two parts: the main body 1 and the riveted part 2. During the processing stage, the overall shape of the main body 1 and the riveted part 2 can be produced by machining, and the melt groove 3 between the main body 1 and the riveted part 2 can be repaired. After forming, the sealing riveted bushing is electroplated so that the outer surface of the sealing riveted bushing meets the basic use requirements. Then, the melt groove 3 between the main body 1 and the riveted part 2 is coated with glue so that the outer surface of the melt groove 3 is covered with glue for sealing, ready for subsequent use. Finally, the sealing riveted bushings with glue coating are selected and quality inspected, and the sealing riveted bushings that meet the preset quality are selected for subsequent riveting.

[0035] With the above structure, see Figure 3 When in use, the operator only needs to install the sealing riveting bushing to one side of the mounting plate 100. Specifically, the mounting hole of the mounting plate 100 is sleeved on the outside of the riveting part 2. Then, the second side of the body 1 is placed on the lower mold 6, and the upper mold 5 of the corresponding size is selected, so that the riveting mechanism 51 of the upper mold 5 is pressed downward in the direction of the riveting part 2. The axis of the riveting mechanism 51 coincides with the axis of the riveting part 2. During the pressing process, at least part of the inner wall of the riveting part 2 first contacts the pressing riveting mechanism 51, and the pressing mechanism 51 continues to press downward, so that the riveting mechanism 51 applies a force mainly in the radial direction to the riveting part 2. Under the action of the above force, the riveting part 2 is pressed forward. It is turned outward in one step, and a force mainly w is applied to the inner wall of the mounting hole of the mounting plate 100 outside the riveted part 2. The metal material of the mounting plate 100 at the inner wall of the mounting hole is squeezed and deformed under the action of the radial force and overflows to the periphery. At the same time, due to the limitation of the upper mold 5 on the outer periphery of the riveting mechanism 51 and the limitation of the first surface of the main body 1, the metal material of the mounting plate 100 flows to the concave melt groove 3 area between the riveted part 2 and the main body 1 until the upper mold 5 is completely pressed down, so that the riveted part 2 is in the maximum turned outward state under the extrusion of the riveting mechanism 51 of the upper mold 5, and the concave melt groove 3 between the riveted part 2 and the main body 1 is filled with the deformed mounting plate 100.

[0036] It is worth noting that, in the above process, as the metal material of the mounting plate 100 flows toward the concave melt groove 3 between the riveted portion 2 and the main body 1, the deformed mounting plate 100 comes into contact with the glue 4 on the surface of the melt groove 3, and the deformed mounting plate 100 continuously presses the melt groove 3, so that the glue 4 on the surface of the melt groove 3 is completely adhered to the deformed mounting plate 100, so that the mounting plate 100 and the melt groove 3 are in a state of complete sealing and isolation by the glue 4. In other words, because the mounting plate 100 and the melt groove 3 are completely blocked by the glue 4, after the mounting plate 100 and the sealing pressure riveting bushing are completely riveted, the connection between the mounting plate 100 and the sealing pressure riveting bushing is in a completely sealed state, thereby avoiding the problem of insufficient sealing between the mounting plate 100 and the sealing pressure riveting bushing due to unstable riveting and other reasons in the existing embodiment when there is no glue 4 at the melt groove 3, resulting in air and liquid leakage. Therefore, this embodiment achieves efficient and stable riveting by accommodating the deformed mounting plate 100 with the help of the melt groove 3 structure, and at the same time, the sealed riveted bushing after riveting has excellent sealing performance with the help of the glue 4 on the surface of the melt groove 3.

[0037] Furthermore, in this embodiment, the coating glue 4 is set to epoxy resin glue or polyurethane glue, which is relatively cheap, easy to obtain, easy to apply, and has stable chemical properties. In the above-mentioned riveting effect, in addition to being able to achieve the preset sealing effect, the high viscosity of epoxy resin glue or polyurethane glue can also further improve the mechanical connection strength between the mounting plate 100 and the sealing pressure riveted bushing, thereby avoiding the separation between the mounting plate 100 and the sealing pressure riveted bushing caused by the fracture or deformation of the metal structure in some cases. The specific material of the coating glue 4 can be selected according to actual cost control, and the use of other types of glue does not deviate from the usage scenarios of this embodiment.

[0038] Furthermore, after riveting is completed, the axial dimension of the riveted portion 2 is the same as the axial dimension of the mounting plate 100. That is, when the riveted portion 2 is not completely deformed, the axial dimension of the riveted portion 2 is slightly larger than the axial dimension of the mounting plate 100. During the gradual riveting process, the riveted portion 2 is subjected to the extrusion force of the riveting mechanism 51, causing the riveted portion 2 to turn outward and squeeze the mounting plate 100. In the process of the riveting mechanism 51 squeezing the riveted portion 2 downward, the degree of the outward turning of the riveted portion 2 gradually increases until the riveted portion 2 is completely turned outward. When the riveted portion 2 is completely turned outward, the amount of pressure exerted by the riveted portion 2 on the mounting plate 100 is just enough to fill the melt groove 3. The upper mold 5 can fully contact the first surface of the body 1 to limit the mounting plate 100, thereby preventing the mounting plate 100 from warping after being squeezed, which does not meet the quality requirements.

[0039] Further, see Figure 1The main body 1 and the riveted portion 2 are configured as an integrally formed structure, with a smooth transition between the inner ring wall of the main body 1 and the inner ring wall of the riveted portion 2. In other words, in this embodiment, the main body 1 and the riveted portion 2 form a single inner ring, facilitating the use of the connection function of the sealed press riveted bushing.

[0040] Of course, in another embodiment, there are the following differences: the inner ring of the main body 1 and the riveted portion 2 can be provided with a stepped structure to facilitate the connection of the corresponding size of the clip, which can be set according to the actual needs of the clip.

[0041] Furthermore, the adhesive coating 4 at least partially covers the mounting plate 100 that has deformed after riveting, thereby completely sealing the connection between the mounting plate 100 and the sealing press-riveted bushing. Specifically, in this embodiment, the adhesive coating 4 completely covers the outer surface of the melt groove 3, thereby maximally adhering to the mounting plate 100 that has flowed therein after deformation, thereby achieving a seal.

[0042] In the riveting device used in the aforementioned riveting process, the diameter of the riveting mechanism 51 of the upper die 5 is between the maximum and minimum diameters of the flap 2. That is, as the riveting mechanism 51 presses downward, the head of the riveting mechanism 51 can first pass through the largest opening of the flap 2 without obstruction. Furthermore, the riveting mechanism 51 has a preset axial thickness, and during its downward movement, the head of the riveting mechanism 51 can contact the inner wall of the flap 2 in an area adjacent to the thickness of the mounting plate 100 along the axial direction. After the riveting mechanism 51 is fully pressed downward, it can cause the flap 2 to be turned outward to a sufficient degree, allowing a preset amount of the mounting plate 100 to be squeezed into the melt groove 3.

[0043] In the final state of the above-mentioned riveting, the area of ​​the upper mold 5 except the riveting mechanism 51 can be completely fitted with the top surface of the mounting plate 100, and can also contact the top of the riveted part 2. At the same time, the riveted part 2 is turned outward to a preset state, and the mounting plate 100 is deformed to completely fill the melt groove 3.

[0044] like Figure 4 The figure shows an embodiment of a usage scenario of a sealed riveted bushing. After riveting is completed, the top of the mounting plate 100 is still a complete plane. Therefore, another connecting plate 200 can be set on the top of the mounting plate 100 and connected to other components at the bottom through the holes of the sealed riveted bushing.

Therefore, all equivalent technical changes made using the contents of the description and drawings of the present invention are included in the scope of the patent application of the present invention.

[0047] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and variations to the present application without departing from the spirit of the present application. It is intended that the appended embodiments include these modifications and variations without departing from the present application.
