Description

Technical Field

[0001] The utility model relates to the technical field of pull rivet nuts, in particular to an anti-slip riveted nut. Background Art

[0002] Rivet nuts are also called pull rivet nuts. Pull rivet nuts are often used in situations where the internal space is small and the nut is installed outside. There is a thread inside the pull rivet nut for threaded connection with the screw. Usually when the screw and the pull rivet nut are connected, the contact between the pull rivet nut and the screw is a direct contact between two metal planes, which will cause a gap between the screw and the pull rivet nut, affecting the sealing.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0019] The utility model provides Figure 1-4 An anti-slip riveted nut shown includes a nut body 1 and a disc 2. The outer wall at the top of the nut body 1 and the bottom end of the disc 2 are respectively provided with a first anti-slip pattern 4 and a second anti-slip pattern 5 for anti-slipping. The interior of the nut body 1 is provided with an inner wall thread 3 for threaded connection with a bolt. A sealing assembly for sealing the disc 2 and the screw is provided on the top of the disc 2. The sealing assembly includes a sealing ring 6. A limiting piece 7 for installing the sealing ring 6 is provided inside the sealing ring 6.

[0020] Specifically, the top of the nut body 1 is fixedly connected to the bottom end of the disc 2, an insertion groove for inserting a bolt is provided at the top of the disc 2, an inner wall thread 3 is provided at the bottom of the inner wall of the nut body 1, and a first anti-slip pattern 4 is provided at the contraction section at the top of the nut body 1. The vertical cross-section of the first anti-slip pattern 4 is shuttle-shaped, and the vertical cross-section of the second anti-slip pattern 5 is triangular.

[0021] Furthermore, the nut body 1, the disc 2 and the inner wall thread 3 constitute the existing rivet bolt, and the nut body 1 is inserted into the hole of the installation object, and the bolt is inserted into the interior of the nut body 1 through the insertion groove. As the installation tool drives the bolt to rotate, the nut body 1 and the inner wall thread 3 are meshed with each other, thereby driving the end of the nut body 1 away from the disc 2 toward the disc 2, thereby extruding and deforming the contraction section of the nut body 1, thereby cooperating with the disc 2 to complete the installation of the nut body 1 and the object. The nut body 1 and the disc 2 are cast in one piece, and the nut body 1 and the disc 2 are made of stainless steel. The stainless steel rivet nut has many advantages, mainly including: strong corrosion resistance: stainless steel rivet nuts have good corrosion resistance in humid and corrosive environments, are not easy to rust, can maintain a smooth surface, and extend service life. At the same time, they have good aesthetics: stainless steel rivet nuts have exquisite appearance, high gloss, are not easy to rust, and can maintain long-term aesthetics, and High strength: Stainless steel rivet nuts have good strength and hardness, are suitable for various engineering occasions, can withstand certain tensile and shear forces, and are easy to process: stainless steel is relatively hard and can be easily processed into rivet nuts of various shapes and specifications, which are suitable for connection requirements of different sizes and shapes. There are multiple first anti-slip patterns 4, and multiple first anti-slip patterns 4 are annularly arranged on the outer wall of the contraction section of the nut body 1, so that when the contraction section shrinks, the first anti-slip patterns 4 form a concave and convex plane, so that when it contacts the surface of the object, the friction with the contact surface can be increased. At the same time, there are multiple second anti-slip patterns 5, and multiple second anti-slip patterns 5 are annularly arranged at the bottom end of the disc 2. When the bolt and the nut body 1 are installed, the disc 2 will be squeezed, so that the bottom end of the disc 2 contacts the surface of the object. The concave and convex surface formed by the second anti-slip patterns 5 can increase the friction with the surface of the object, thereby ensuring that the nut body 1 and the disc 2 are installed. Prevent the riveted nut from slipping.

[0022] Specifically, an annular groove for placing the sealing ring 6 is opened at the top of the inner wall of the insertion groove, and the limiting member 7 includes a fixing plate 71, the bottom end of the fixing plate 71 is fixedly connected to the bottom end of the inner wall of the annular groove, and the fixing plate 71 is fixedly connected to the side facing the sealing ring 6 with an extrusion tooth 72 for limiting the movement of the sealing ring 6, and the height of the fixing plate 71 is 0.5 times the height of the annular groove.

[0023] Furthermore, the sealing ring 6 is placed in the annular groove, and the top of the sealing ring 6 is 2 mm higher than the top of the disc 2. At least three groups of limiting members 7 are arranged, which are respectively and evenly spaced and annularly distributed at the bottom end of the inner wall of the annular groove. The sealing ring 6 is an annular ring made of rubber material. The bottom end of the fixing plate 71 is fixed to the annular groove by welding. The extrusion teeth 72 are arranged on the side of the top of the fixing plate 71 close to the sealing ring 6. The extrusion teeth 72 and the fixing plate 71 are produced by an integrated casting method. When the sealing ring 6 is placed in the annular groove, the fixing plate 71 can support the sealing ring 6 to ensure the annular shape of the sealing ring 6. At the same time, the outer wall of the inner ring of the sealing ring 6 contacts the fixing plate 71, and the fixing plate 71 will squeeze the sealing ring 6. At the same time, the tooth shape of the fixing plate 71 will increase the friction between the sealing ring 6 and the sealing ring 6, thereby ensuring that the sealing ring 6 is stably placed in the annular groove. When the bolt is installed, the sealing ring 6 will not be displaced at will. Therefore, when the bolt is installed, the bottom end of the nut and the top end of the disc 2 fit each other to squeeze the sealing ring 6, thereby forming a seal between the nut and the disc 2.
