Description

Technical Field

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

[0002] In the processing of some metal sheets, riveted nuts are generally used to achieve the predetermined installation function. However, the existing structure generally uses rivet columns to rivet and then fix them before tapping to form nuts. Therefore, there are more production processes, the production efficiency is slow, and the production cost is also high.

[0003] Of course, there are also structures using hollow nuts, such as Chinese patent CN200910175175.5, which uses rivet curling to achieve mutual fixation, but this structure is not suitable for structures with solid rivets. Utility Model Content

[0004] The main purpose of the utility model is to propose a waterproof rivet nut structure, aiming to design a rivet nut structure to realize the installation of a solid nut, while ensuring the sealing between the rivet nut and the plate.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a waterproof pressure riveting nut structure, comprising:

[0006] A main body, wherein the main body is provided with a central axial hole, the central axial hole is provided with an internal thread, and the bottom of the central axial hole is a solid structure;

[0007] A flange seat, the flange seat is extended outward from the middle of the main body, and a concave limiting groove is provided on the inner side of the flange seat;

[0008] The convex eaves are arranged on the outer peripheral wall of the upper end of the main body, the convex eaves are arranged above the limiting groove and are arranged relatively, and the limiting groove and the convex eaves surround a pressing area.

[0009] In actual installation, the main body is placed into the rivet hole of the plate, and then the plate is squeezed and deformed by a riveting press and pressed into the space between the limit groove and the convex eaves. Through the offset pressing interval, when the rivet nut is fixed to the plate, a stepped offset waterproof structure can be formed, which not only ensures a stable combination, but also ensures the watertightness of the rivet nut after installation on the plate. The structure is simple and stable. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0017] like Figures 1 to 3 As shown, a waterproof pressure riveting nut structure includes:

[0018] A main body 1, wherein the main body 1 is provided with a central shaft hole 11, wherein the central shaft hole 11 is provided with an internal thread 10, and the bottom of the central shaft hole 11 is a solid structure;

[0019] A flange seat 2, the flange seat 2 is extended outward from the middle of the main body 1, and a concave limiting groove 21 is provided on the inner side of the flange seat 2;

[0020] The convex eaves 3 are arranged on the outer peripheral wall of the upper end of the main body 1. The convex eaves 3 are arranged above the limiting groove 21 and are arranged relatively. The limiting groove 21 and the convex eaves 3 form a pressing area.

[0021] In actual installation, the main body 1 is placed into the rivet hole of the plate, and then the plate is squeezed and deformed by a riveting press and pressed into between the limit groove 21 and the convex eaves 3. Through the offset pressing interval, when the rivet nut is fixed to the plate, a stepped offset waterproof structure can be formed, which not only ensures a stable combination, but also ensures the watertightness of the rivet nut after being installed on the plate. The structure is simple and stable.

[0022] Specifically, the bottom end of the central axis hole 11 is in an arc shape 6, and a pressure rod can be inserted therein to play a role of limiting or fixing.

[0023] Furthermore, the upper section of the main body 1 includes a first vertical section 31 (i.e., the position of the convex eaves), a second vertical section, and a sloped section 33 that tapers from the first vertical section 31 toward the second vertical section 32, thereby forming a guiding and limiting structure, thereby facilitating the installation of the flange seat 2.

[0024] In the embodiment of the utility model, the convex eave 3 is integrally stamped outward from the upper end of the main body 1, thereby ensuring the structural stability of the rivet nut.

[0025] Specifically, the outer diameter of the convex eave 3 is larger than the outer diameter of the limiting groove 21. Therefore, after the plate is subjected to the extrusion force, the inclined surface section can be deformed and inserted into the limiting groove 21, and the folded structure is formed to fit with the convex eave 3 and the limiting groove 21 respectively, thereby providing a staggered sealing structure.

[0026] In the embodiment of the utility model, a chamfer 5 is provided at the lower end of the main body 1 .

[0027] In the embodiment of the utility model, an upper wall of the flange seat 2 is provided with an integrated anti-rotation seat 4, and the anti-rotation seat 4 is provided with a limiting groove 21 or a limiting block.

[0028] In the embodiment of the utility model, the anti-rotation seat 4 is a gear-shaped structure. Through the convex tooth structure, multi-point limiting and fixing can be achieved after riveting, which effectively ensures the tensile strength of the rivet nut and improves the bonding degree with the plate.

[0029] Specifically, the main body 1 is made of aluminum alloy material or stainless steel material, thereby achieving a better anti-rust effect.

[0030] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
