Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a pressure riveted nut with a waterproof limiting structure. Background Art

[0002] With the development of technology, new types of self-clinching nuts continue to appear on the market. These new nuts usually include structures such as nut seats, embossed teeth, guide columns and nut outer seats. Height adjustment is achieved through internal threads and mounting plug-ins. In addition, the production process of self-clinching nuts has also been optimized, including wire drawing, annealing, surface phosphating, cold heading, tapping, heat treatment and electroplating to improve product quality and production efficiency. There is currently a type of self-clinching nut on the market that has sealing properties. It uses a labyrinth-shaped convex edge on the end face of the self-clinching nut to prevent water from easily penetrating from the connection between the self-clinching nut and the substrate. This type of self-clinching nut has applied for a utility model patent, and the patent name is a waterproof self-clinching nut (application number: 201710238256.X). However, the labyrinth-shaped convex edge of this waterproof self-clinching nut is concentric with the nut body, and teeth need to be set later to prevent the nut from rotating. The structure is complex, the waterproof effect is poor, and the production cost is high. Utility Model Content

[0019] The present invention is a mixing station construction safety punching device embodiment as shown in the figure, in order to achieve the above purpose, the present invention provides a To achieve the above purpose, the present invention provides the following technical solutions: including a nut body 1 and an annular boss 2 concentrically arranged with the nut body 1, at least one pressure riveted ring rib 3 is arranged between the upper end face of the nut body 1 and the annular boss 2, at least one of the pressure riveted ring rib 3 and the annular boss 2 is eccentrically arranged, the upper end face of the pressure riveted ring rib 3 is provided with a deformation end for cooperating with the sealing groove 4 of the pressure riveting part of the substrate for sealing, and at least one pressure riveted ring rib 3 is provided, and at least one pressure riveted ring rib 3 is provided. The rib 3 and the annular boss 2 are eccentrically arranged, which can make the self-riveted nut not easy to rotate after assembly is completed. The eccentrically arranged self-riveted ring rib 3 can produce different distances between the self-riveted ring rib 3 and the annular boss 2, so that the shape between the self-riveted ring rib 3 and the annular boss 2 is non-annular and not easy to rotate. Such a structural arrangement can eliminate the need for the structure of the limiting teeth 6, which is more convenient to manufacture, saves materials, and has a simple structure. A deformable end is provided on the upper section of the self-riveted ring rib 3, and the deformable end can contact the sealing groove 4 at the self-riveting part of the substrate and can deform and fill the sealing groove 4 at the self-riveting part after self-riveting, thereby improving the sealing effect; the nut The upper end surface of the body 1 is provided with two riveting ring ribs 3, one of which is concentric with the annular boss 2, and the other is eccentric with the annular boss 2. The two riveting ring ribs 3 do not intersect with each other. The two riveting ring ribs 3 are provided so that the upper end surface of the riveting nut and the base material can be riveted to form a maze-like waterproof structure, and one of the riveting ring ribs 3 is concentric with the annular boss 2 to avoid the nut from rotating after riveting, which has a limiting effect, a simple structure and better waterproof effect; the riveting ring rib 3 is a trapezoidal riveting ring rib 3 with an inclined side, and a trapezoidal riveting ring rib 3 with an inclined side is adopted. The riveting ring rib 3 can make pressure riveting more convenient and reduce production costs; the deformation end is a waterproof putty 5 for inserting into the sealing groove 4 of the pressure riveting part of the substrate and capable of pressure riveting and deformation. The waterproof putty 5 is set as the deformation end of the pressure riveting part. The waterproof putty 5 is soft and more easily deformed after being pressed. The waterproof putty 5 has a better waterproof effect and is often used in engineering construction; a limiting portion is set on one side wall of the pressure riveting ring rib 3. The limiting portion is evenly distributed along the circumference of one side wall of the pressure riveting ring rib 3. The setting of the limiting portion on one side wall of the pressure riveting ring rib 3 can further improve the limiting effect on the basis of setting an eccentric pressure riveting ring rib 3;The limiting portion is a limiting tooth 6 evenly distributed on the side wall of the riveting ring rib 3. The limiting teeth 6 are set as the limiting portion, and the limiting teeth 6 are evenly distributed to improve the connection strength and stability of the connection. When implementing this scheme, those skilled in the art can use traditional riveting methods for riveting, but the riveting ring rib 3 and the deformed end on the riveting ring rib 3 set in this embodiment can have the effect of waterproof sealing and preventing the riveting nut from rotating after riveting. When riveting the riveting nut, those skilled in the art place the deformed end corresponding to the sealing groove 4 on the substrate, and then place the riveting ring rib 3 corresponding to the sealing groove 4. After that, those skilled in the art can perform riveting. At this time, the deformed end can contact the inner wall of the sealing groove 4 after riveting and be deformed under pressure and can fill the sealing groove 4 on the substrate. At this time, the riveting ring rib 3 can also pass through Pressure riveting causes the connection between the substrate and the pressure riveting ring rib 3 to be deformed under pressure to achieve the pressure riveting effect and improve the sealing performance. Since at least one pressure riveting ring rib 3 is eccentrically arranged with the annular boss 2, after pressure riveting, the distance between the outer periphery of the pressure riveting ring rib 3 and the axis of the annular boss 2 is different. The shape after pressure riveting is also a non-annular structure, which can prevent the connection between the pressure riveting nut and the substrate from rotating, has a limiting effect, and improves stability. In this solution, in order to avoid insufficient connection strength between part of the substrate and the pressure riveting ring rib 3, a limiting tooth 6 is provided on the pressure riveting ring rib 3 for circumferential limiting, further strengthening the limiting effect. The substrate used in conjunction with the pressure riveting nut in this solution is a substrate with a sealing groove 4. Those skilled in the art can set the required adaptive sealing groove 4 on the substrate in advance to improve the sealing effect and connection strength.
