Technical Field
The invention belongs to the technical field of fasteners, and particularly relates to a waterproof press riveting screw.
Background
Fasteners are a generic term for a class of mechanical parts used to fasten two or more parts (or components) together as a unit. The self-fastening fastener has the advantages of quick, efficient and reliable installation, convenient assembly, high pushing, pulling and twisting performance, wide application range of materials, specification serialization and the like, and is widely applied to connection of sheet metal parts.
Screws are one of the most widely used types of fasteners. With the continuous change and development of the use range and the use environment, more demands are also put on the screw. In particular, in some cases, it is desirable that the screw has a waterproof sealing function. The existing screw sealing and waterproofing methods are roughly of the following types:
1. coating sealant at the fastening connection part of the screw and the part;
2. riveting and sealing through interference fit of the screw and the part;
3. the screw is in threaded connection and sealing through interference fit of the screw and the part;
4. riveting the part by a sealing rubber ring between the screw and the part;
5. the screw connection of a sealing rubber ring is arranged between the screw and the part;
6. riveting by adding pure aluminum/copper sleeves (sheets and pads) between the screws and the parts;
7. the screw connection of pure aluminum/copper sleeve (sheet, pad) is added between the screw and the part;
8. mixing and sealing the above components.
These existing screw-sealing waterproof ways have the following disadvantages:
1. coating a sealant: the process is complicated, the construction is complicated, the labor condition is poor, the efficiency is low, the connection quality is unstable, and the like.
2. Interference fit: the hole and the shaft matched with the hole have the advantages of high processing difficulty, low efficiency and high assembly quality requirement.
3. Sealing a rubber ring: high cost, low efficiency, high assembly quality requirement and limited working temperature.
4. Adding a pure aluminum/copper sleeve: the processing difficulty of parts is big, the efficiency is low, the assembly quality requirement is high.
In the existing modes, certain waterproof grade and waterproof effect cannot be met according to the requirements of GB4208 protection grade (IP code) of shells and IEC60529 standard.

Detailed Description
As shown in fig. 1 to 3, a waterproof clinch screw includes:
the screw head 1 is positioned at the head of the waterproof rivet pressing screw 100;
the screw rod 2 is connected with the screw head 1 and axially extends to the tail part of the waterproof rivet pressing screw 100;
and the screw teeth 3 are arranged on the peripheral ring of the screw rod 2.
The end face of the screw head 1 connected with the screw rod 2 is provided with a plurality of protruding tooth-shaped sealing geometric bodies 4. The plurality of tooth-shaped sealing geometric bodies 4 are sequentially and concentrically arranged outwards from the periphery of the screw rod 2. The tooth-shaped sealing geometric bodies 4 are circular and concentric with the axis of the screw rod 2. In this embodiment, the tooth shape of the tooth-shaped sealing geometry 4 is trapezoidal. Of course, other tooth shapes can be used for the toothed sealing geometry 4 for the sealing and water-proof effect.
The edge of the end face of the screw head 1 connected with the screw rod 2 is also provided with a raised annular closed flange 5 along the circumferential direction, the flange 5 is uniformly distributed with a plurality of locking teeth 51 along the circumferential direction, and the locking teeth 51 extend along the radial direction of the flange 5 and face the direction of the screw rod 2. The flange 5 is concentric with the toothed sealing geometry 4. The height of the flange 5 is higher than the height of the toothed sealing geometry 4.
The waterproof rivet pressing screw can be used for fastening and connecting sheet metal parts. The use method is as follows:
1. and a light hole is formed on the base material which is matched and fastened with the waterproof rivet pressing screw 100 through processes such as stamping and the like.
2. The screw rod 2 of the waterproof rivet pressing screw 100 is inserted into the unthreaded hole, and the screw head abuts against the surface of the substrate.
3. The waterproof rivet pressing screw is fixed on the base material in a pressing mode at the screw head, and the surface of the base material is deformed in a pressing mode to form a surface matched with the toothed sealing geometric body 4 and the flange 5.
4. Another substrate for mating fastening is in mating threaded connection with the screw 2 of the waterproof clinch screw 100, so that the two substrates are fastened together in relation to each other.
After the fastening operation, the tooth-shaped sealing geometric bodies 4 form a structure similar to labyrinth seal on the base material, so that the sealing performance of the waterproof clinch screw 100 is greatly improved, and the requirement of waterproofness can be effectively met.
Due to the arrangement of the locking teeth 51 on the flange 5, the waterproof rivet pressing screw 100 can be prevented from rotating with the base material in the using process, and meanwhile, the self-fastening of the outer diameter of the screw rod 2 and the outer diameter of the screw head 1 of the waterproof rivet pressing screw 100 is achieved. The water seepage caused by looseness of the base material and the outer side of the screw head 1 of the waterproof press-riveting screw 100 due to some reason can be effectively prevented. In this way, waterproof 100 is efficiently and reliably connected to the substrate, and the connected assembly can withstand excellent mechanical loads such as pushing, pulling, twisting, shearing, and the like.
Moreover, since the height of the flange 5 is higher than the height of the tooth-shaped sealing geometry 4, the waterproof performance is further improved
The invention can realize connection without special tools, and has simple and efficient installation process. The connection is realized at a certain pressure and a working stroke, and the high torsion resistance and the high push-out resistance are realized.
The invention is suitable for metal plates of steel, stainless steel, copper, aluminum alloy and the like. Generally, the hardness of the waterproof clinch screw is greater than the hardness of the substrate.
The terms of orientation, such as front, back, left, right, up and down, referred to above are defined in terms of the orientation of the waterproof clinch screw in normal use.
As described above, the present invention has been explained fully in accordance with the gist of the present invention, but the present invention is not limited to the above-described examples and implementation methods. A practitioner of the related art can make various changes and implementations within a range allowed by the technical idea of the present invention.
