Innovative structure of waterproof screw washer

This creation is about a waterproof screw washer; more specifically, it refers to an innovative structure of a waterproof screw washer.

In general, the gasket of the waterproof screw is used to protect the screw from the chance of contact with water after locking, thereby reducing the occurrence of rust. So far, there are many waterproof screw gaskets for the gasket. The waterproof function has been improved as described in the following paragraph:

Please refer to FIG. 1 and FIG. 2 . FIG. 1 is a schematic perspective view of a conventional one. FIG. 2 is a schematic view of a conventional locking screw. The conventional waterproof screw 1 includes a nut 11 , a thread 12 connected downwardly from the nut 11 , and a perforation. (not shown) may be inserted through the thread 12 and sleeved on the lower end of the nut 11 of the waterproof gasket 13, the waterproof gasket 13 is usually a waterproof material such as rubber, PP, PE, PU paint, and the shape is usually O The annular shape is sealed by the waterproof gasket 13 to seal the gap between the locked object and the nut 11 to achieve a waterproof effect.

For the literature on screw gaskets with waterproof function, several patents are as follows:

M356027 discloses a screw washer comprising a gear body and a gasket for threading; wherein the gasket has upper and lower sides, and a positioning hole penetrating the upper and lower sides, and the positioning hole is above The aperture of the aperture edge is larger than the aperture of the lower aperture edge to form a tapered wall surface; further, the aperture body is formed with a perforated surrounding wall, and the surrounding wall protrudes from the axis with a plurality of latching portions, each card The end edge of the crotch portion has a top block facing downward in the axial direction, so that when the screw is worn, the orientation of the top block and the structure of the tapered wall surface can be quickly penetrated, and the shape can be limited. The top block and the lower hole edge are stably supported by a plurality of points, so that the tilting phenomenon is not easy to occur, and the screw washer can be tightly coupled to the lock compound when the lock is subsequently engaged, thereby effectively increasing the waterproof effect of the screw washer.

M352597 discloses an improved structure of a screw gasket, comprising a bottom surface of an arched ring-shaped metal sheet combined with a gasket, wherein the outer hole of the annular metal sheet is a socket forming an inclined circumference, and the outer periphery is formed to abut the edge surface of the gasket. The outer peripheral edge of the lower fold, the hole diameter of the hole in the gasket is smaller than the hole diameter of the metal piece socket, and the bottom surface forms two inner and outer loops for pressing the workpiece; when the punch is formed, the outer circumference of the metal sheet can be combined with the socket. The inclined circumference is tightly combined with the gasket to form a strong joint and is not easy to fall off, and the outer peripheral edge of the lower fold can be forced to squeeze the screw gasket structure with the deep socket of the inclined peripheral edge punching, and when the screw is provided, the gasket can be effectively prevented. It expands outward and forms a double impinging effect to achieve a completely sealed penetration effect, that is, the cap can be deeper into the set to avoid scratching multiple effects of better safety.

However, after using the conventional screw gasket for a period of time, it has the following disadvantages: It needs to be improved: 1. So far, most of the conventional methods have been to improve the shape of the waterproof gasket or to reinforce the structure, although at the beginning They can be locked very tightly, but after a period of use, the material of the waterproof gasket may be permanently compressed (oxidized by the material), that is, it will lose its elasticity and lose its waterproof properties, while the nut and the object A gap may be formed between them (see gap A in Fig. 2), which causes rainwater to penetrate into the thread, which may cause the screw to be rusted by rain. 2. According to the above, when using a gap between the nut and the object for a period of time, the general practice is to fill the gap with a silicone resin (commonly known as: silicon) to fill the gap and reinforce the waterproof effect. In other words, if the object is a painted steel plate, the addition of the epoxy resin will combine the potassium with the painted steel plate to achieve the reinforcing waterproof effect. However, the waterproof durability of the epoxy resin is at most 1 to 2 years, so after a while, It needs to be replenished, which is very inconvenient for the user.

In view of this, I have been engaged in R&D experience in related fields for many years, and have conducted in-depth discussions on the above-mentioned shortcomings, and actively sought solutions based on the above-mentioned needs. After a long period of hard work and many tests, I finally completed this creation.

The main advantage of this creation is that by changing the waterproof gasket from the solid state to the adhesive rubber of the adhesive state, when the screw is locked, the rubber can be completely covered between the nut and the locked solid, and the adhesive rubber is A long-lasting substance that has long-term and excellent water resistance.

In order to achieve the above object, the present invention provides an innovative structure of a waterproof screw washer, which comprises a nut, a thread connected to the lower end of the nut and used for locking the object; and characterized in that: the screw and the nut are connected at the joint Adhesive rubber; wherein the adhesive rubber can be butyl rubber, and the butyl rubber is in a thick state, and can maintain its viscosity and elasticity within -30 ° C ~ 130 ° C, so it can last for a long time The waterproof effect of time.

In the foregoing, when the user uses the original locking object, the object may be painted steel plate, galvanized steel (C-shaped steel), wood, etc., and in the process of locking, when the adhesive rubber is in contact with the object, It is a thick state and has viscous and elastic properties, so the adhesive rubber will expand with the locking action, and extend the coverage area, and completely fit the nut to the object according to the shape of the surface of the object. The gap, so an excellent waterproof effect is achieved.

For a more detailed understanding of the purpose, function, features and structure of the present invention, the preferred embodiments and the accompanying drawings are set forth below.

Please refer to FIG. 3 to FIG. 4 at the same time. FIG. 3 is a perspective view of a preferred embodiment of the present invention, and FIG. 4 is a schematic diagram of the locking of the preferred embodiment of the present invention.

As shown, the innovative structure 2 of the waterproof screw washer of the preferred embodiment of the present invention comprises a nut 21, a threaded end 22 connected to the lower end of the nut 21 for locking the object 3; characterized in that: the thread 22 An adhesive rubber 23 is provided at a joint with the nut 21.

In the foregoing, when the user uses the present invention to lock the object 3, the object 3 may be a painted steel plate, a galvanized steel (C-shaped steel), wood, etc., and in the present locking process, when the adhesive rubber 23 and the object 3 are adhered When it is in contact, because it is in a thick state and has the characteristics of adhesion and elasticity, the adhesive rubber 23 can be extended with the locking action, and the coverage area thereof is extended even when the original thread 22 is penetrated. In the case of the object 3, the adhesive rubber 23 can be filled with the thread 22 to automatically fill the gap between the thread 22 and the object 3, so that the gap between the object 3 and the thread 22 can be filled except for the surface of the object 3. In order to achieve a completely close-fitting appearance, in addition to strengthening the fixing effect, it also forms an excellent waterproof effect.

In addition, in the process of locking, the inclination between the screw 22 and the object 3 is inadvertently 1 degree to 9 degrees, or the inclination angle between the screw 22 and the nut 21 is generated during the manufacturing process, and the inclination angle can be generated. When locked, the adhesive rubber 23 can automatically fill the gap between the inclination angle and the object 3 through the thick characteristic of the adhesive rubber 23, thereby enhancing the fixing effect of the locking and enhancing the waterproof effect.

Among them, it is worth mentioning that the adhesive rubber 23 can be butyl rubber as the main component, and the butyl rubber is in a thick state, and can maintain its viscosity within -30 ° C ~ 130 ° C. And elasticity, as described in detail, butyl rubber can remain uncured at -30 ° C, and maintains a non-melting state at 130 ° C; if the creation and the lacquered steel plate are locked, it can prevent rainwater from penetrating and avoid the lacquered steel plate. Subject to oxidation.

Following the foregoing, in the production of the present invention, the adhesive rubber 23 (illustrated by the example of butyl rubber in this embodiment) can be adjusted according to the flatness or smoothness of the surface of the object to be locked, or It can also be adjusted according to user needs, so the degree of viscosity (viscosity and elasticity) can be customized.

In summary, the innovative structure of the waterproof screw washer described in the present case is incapable of the prior art technology of the same type of technology, that is, the present case has the following advantages: 1. The creation system can replace the general rubber by adhesive rubber. The shape of the adhesive rubber is thick and thus has a property of elastic change, so that the gap between the nut and the object can be completely filled to achieve a completely waterproof effect. 2. At the same time, the creation of the adhesive can also be used to strengthen the locking between the screw and the object when the screw is locked into the object due to its thick shape. The effect can also have better waterproof effect. 3. When butyl rubber is used as the main component of the adhesive rubber, its characteristics will not affect its adhesion and elasticity between -30 ° C and 130 ° C. It can be waterproof for a long time and does not need to replenish the waterproof material in the future. 4. The adhesive rubber of this creation is made of waterproof material, which can adjust the proportion of the adhesive component according to the locked object or the user's demand, so it can have multiple or customized effects.

Therefore, this creation has excellent progress and practicality in similar products. At the same time, after checking the technical literature on such structures at home and abroad, it has not been found that the same or similar structure exists before the application of this case, so this case It should meet the patent requirements of "creative", "combined with industrial use" and "progressive", and apply in accordance with the law.

It is to be understood that the above-mentioned preferred embodiments of the present invention are intended to be included in the scope of the present invention.
