Description

Technical Field

[0001] The utility model relates to the technical field of nuts, and particularly relates to a waterproof and anti-rotation lantern rivet nut. Background Art

[0002] UTV, the full name is Utility Terrain Vehicle, and its Chinese name is farmer vehicle. It is a vehicle designed to travel on various complex terrains. UTV usually has high off-road capabilities and is suitable for use in environments such as mines, the wild, beaches, and mountains. Lantern rivet nuts are often used when installing interior and exterior plastic decorative parts on farmer vehicles.

[0003] The authorized announcement number is CN201526583U, which discloses a lantern-shaped rivet nut. Combining its specification and drawings, its solution changes the cylindrical structure of the rod part of the product, and designs the rod part into a petal-shaped structure with four parts connecting the head and the tail of the rivet nut. After the rivet nut is riveted and deformed, the four petal-shaped riveting belts of the rod part become a cross-shaped press riveting body. This cross-shaped structure can make the rod part sink into the material of the plastic body under strong riveting force. However, this kind of rivet nut cannot achieve waterproofing when riveted on plastic decoration, and it is particularly easy to damage the riveting layer during the assembly process, and it is prone to slipping and even rotation, so it cannot be used, which brings inconvenience during use. Summary of the Invention

[0006] Preferably, the cross-section of the first washer is circular, and the material of the first washer is vulcanized rubber.

[0007] Preferably, an installation through hole runs through the middle of the rivet nut body and the rivet nut retaining ring, and this setting is to enable an external screw to pass through the rivet nut body and the rivet nut retaining ring.

[0008] Preferably, a plurality of limit convex blocks are arranged at one end of the rivet nut body, and a second washer through hole adapted to the shape of the limit convex blocks is arranged at the edge of the first washer through hole.

[0009] Preferably, the rivet nut body includes a threaded portion and a deformable portion. The surface of the deformable portion is provided with a plurality of first cutting grooves, and the shape of the deformable portion after deformation is cross-shaped.

[0010] Preferably, a threaded inner groove is provided inside the threaded portion, and the threaded inner groove can be adapted to an external screw, so as to enable the screw to be threadedly rotated into the threaded portion.

[0011] Preferably, a limiting groove adapted to the shape of the limiting convex block is provided on the surface of the external plastic part, so as to enable the limiting convex block to play a limiting role when the rivet nut is installed on the plastic part.

[0012] Compared with the prior art, the utility model has the following beneficial effects: 1. When installing the rivet nut, the limiting convex block avoids slipping between the plastic part, thereby realizing the installation, which brings convenience during use; 2. After installing the rivet nut, the first washer made of vulcanized rubber deforms and firmly adheres to the surface of the plastic part, thereby playing a waterproof role, which brings convenience during use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following further describes the utility model with reference to the embodiments shown in the drawings:

[0019] As shown in Figures 1 to 4As shown in the figure, a waterproof and anti-rotation lantern rivet nut includes a rivet nut body 1 and a rivet nut retaining ring 2 provided on one side of the rivet nut body 1. A mounting through-hole 11 runs through the middle of the rivet nut body 1 and the rivet nut retaining ring 2. The diameter of the mounting through-hole 11 allows an external screw to pass through. A first groove 21 is provided on one side of the rivet nut retaining ring 2, and a first washer 3 is provided inside the first groove 21. A number of limiting bumps 4 are provided at one end of the rivet nut body 1. A first washer through-hole 31 adapted to the shape of the rivet nut body 1 is provided in the middle of the first washer 3, and a second washer through-hole 32 adapted to the shape of the limiting bumps 4 is provided at the edge of the first washer through-hole 31. This is set to ensure that the first washer 3 can pass through the rivet nut body 1 and be connected inside the first groove 21. Among them, the first groove 21, the first washer through-hole 31, and the second washer through-hole 32 prevent the first washer 3 from shifting to other positions. It should be noted that after the entire rivet nut is installed on an external plastic part 5, the first washer 3 is in contact with its surface. The cross-section of the first washer 3 is circular, and the material of the first washer 3 is vulcanized rubber. This makes the first washer 3 have characteristics such as non-stickiness and not being easily broken. Most rubber products are made of this kind of rubber. It is also called vulcanized rubber, commonly known as rubber or rubber sheet, and has high elasticity, heat resistance, tensile strength, and insolubility in organic solvents, etc.

[0020] In this embodiment, the rivet nut body 1 includes a threaded portion 14 and a deformable portion 12. In order to enable the deformable portion 12 to deform, a number of first cutting grooves 13 are provided on the surface of the deformable portion 12. During the deformation process, the size of the first cutting grooves 13 gradually becomes larger. Moreover, the shape of the deformable portion 12 after deformation is cross-shaped. A threaded inner groove 15 is provided inside the threaded portion 14, and the threaded inner groove 15 can be adapted to an external screw. A limiting groove 51 adapted to the shape of the limiting bumps 4 is provided on the surface of the external plastic part 5. After such a setting, when the external screw rotates in the threaded inner groove 15, the deformable portion 12 will move towards the direction of the first washer 3 until it deforms into a cross shape and firmly adheres to the surface of the external plastic part 5.

[0021] The working principle and usage method of the present utility model:

[0022] First, insert the rivet nut body 1 into the through-hole on the surface of the external plastic part 5 until the limiting bumps 4 are stuck inside the limiting groove 51. At this time, the first washer 3 is in contact with one side of the plastic part 5 surface. Then, insert the external screw into the threaded inner groove 15 and rotate it. During the rotation process, the deformable portion 12 will move towards the direction of the first washer 3 until it deforms into a cross shape and firmly adheres to the other side of the plastic part 5 surface. During this process, the limiting bumps 4 prevent slipping, thus achieving installation, and the vulcanized first washer 3 plays a waterproof role.

[0023] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
