Description

OBJECT OF THE INVENTION

The present invention relates to a modular joint with safety ring for plastic pipes, and more specifically to a quick coupling between two modules provided at the facing ends of the corresponding sections of plastic pipe to be joined, said modules being materialized. quick coupling in aluminum

or similar stainless material.

In the coupling of each module to the respective end of the plastic tube an external clamp participates through which a union between both parts is achieved.

The object of the invention is to achieve optimum sealing, not only in the coupling between the metal modules to the ends of the plastic pipes, but also in the connection between said metal modules and the plastic pipes themselves, in addition to achieving an optimal appearance. external aesthetic in said joining area.

BACKGROUND OF THE INVENTION

Quick coupling systems are known for plastic pipes, which present serious problems when retaining the two coupled sections. Specifically, there is a union of two sections of plastic pipes in which two quick coupling modules are involved, which are metallic and that are coupled to the ends of the plastic pipes to be joined, one of those quick coupling modules being male and another female, incorporating between them a bilabial sealing gasket, as well as retention means between them, with a safety ring that retains and prevents the axial displacement of the male module with respect to the female module.

Furthermore, at the junction between the corresponding metal module and the end of the respective plastic tube, an external clamp participates which by pressure deforms the end section of the plastic tube and is retained by a tooth provided for this purpose on the external surface of the end corresponding to the metal module of the quick coupling.

In this sense, the Utility Model U 200201490 of the same holder can be mentioned, where a configuration and special bonding of a safety ring that participates in the immobilization between the coupled metal modules and to which the ends of the tubes are attached are precisely described. corresponding plastic.

However, in this case the external clamp that participates in the union between each metal module and the end of the plastic tube, is a smooth tubular clamp that does not offer sufficient guarantee in the optimal maintenance of union, nor of course offers the appearance external aesthetic that would be desirable.

DESCRIPTION OF THE INVENTION

The modular union with safety ring for pipe

plastic that is recommended, has been conceived to solve the problem previously exposed and achieve new and notable improvements and performance with respect to the type of joints described above.

More specifically, the union of the invention, while maintaining the retention of each other of the metal modules attached to the ends of the plastic pipes, is based on the fact that the clamp used in the joint between each metal module and the end of the plastic tube , is a clamp that has a pair of deformations or double groove to be placed in correspondence with grooves or annular recesses established for this purpose in the end section of the metal module housed inside the end of the corresponding plastic tube, thus achieving optimal retention and therefore an effective union between the metal module and the plastic tube, in addition to achieving an unbeatable aesthetic appearance of the clamp, since it has two grooves and is of greater length compared to that used conventionally.

In addition, the clamp will preferably be made of aluminum or similar material, that is to say a non-oxidizable material, with a light weight compared to the high weight of the galvanized steel, which is also oxidizable due to the scratches that can occur in the pressing thereof, which will not occur with the clamp used in the present case since the material is not oxidizable.

In summary, by using the new clamp provided at the junction between each metal module and the plastic tube. the following advantages are achieved:

Corrosion of the clamp itself that normally originates as a result of friction is avoided

caused in the pressing process, friction that can

damage the coating leaving small surfaces

scratched and as a consequence unprotected from

corresponding bath, being susceptible to degradation

at those points when it comes to a galvanized clamp,

while using the clamp of the invention, being

of aluminum or stainless material, the

corrosion.

In addition, due to the use of corrosive waters, as use of

fertilizers, mixtures of chemicals, foaming agents,

brackish water, sewage, slurry, etc., can

occur a chemical attack on the metal, accelerating the

corrosion process in the clamp, as is the case with

a conventional steel clamp, which doesn't happen

with the clamp of the invention being aluminum or

similar stainless material.

The aesthetic appearance of the clamp in your

application as an element of union between the

corresponding metallic module and the respective section of the

plastic tube.

A greater guarantee of resistance is achieved in terms of

internal pressure, stretching, traction and shock.

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, the modular joint of the invention is provided to join two plastic tubes (1, 1 ') together, this connection being made by coupling respective metal modules (2, 2'), which they are precisely attached to the ends of those plastic tubes (1, 1 '), as will be discussed later.

The metallic coupling modules (2,2 ') constitute a female and a male, being housed inside one another, partially incorporating the female module (2) a prominence (3) with a lateral opening or cavity (4) for housing a projection (5) provided for this purpose in the male module (2 '), when it is coupled on the female module (2), the coupling being made with the participation of a seal and bilabial joint (6), Y both metal modules (2, 2 ') being retained by means of a ring (7) that is open and their ends are housed in respective holes (8, 9) established for this purpose in prominence

(3) of the female module (2).

The union of each metallic module female (2) and male (2 ') to the respective plastic tubular section (1, 1'), is carried out by means of an external and pressure clamp (10) with a double groove, as it is clearly depicted in figures 1 and 2, whose grooves are facing respective channels or recesses (11) provided for this purpose on the outer face of the tubular section of the metal coupling module (2, 2 '), so that the deformation they produce clamp grooves

(10) causes the thrust towards these grooves or recesses (11) of the plastic pipe (1, 1 '), thus achieving a double retention between plastic pipe (1, 1') and its corresponding metal coupling module (2 , 2 '), as can be clearly seen in Figures 1 and 2, an O-ring (12) having a tightness between the metal module junction section (2, 2') and the respective end section of the tube plastic (1, 1 ').

In accordance with the above, in addition to the advantages corresponding to the impossibility of corrosion of the clamp that participates in the joint, as well as the best aesthetics of the assembly and the greater guarantee of resistance, it can be said that a double tightness is achieved, one corresponding to the one provided by the bilabial joint (6) between the metal modules (2, 2 '), and another one that establishes the joint (12) at each junction between the respective metal module (2, 2') and the corresponding one plastic tube end (1, 1 ').

Also say that the clamp (10) preferably constituted in aluminum, by virtue of its two grooves and the facing grooves 5 (11) of the metal module (2, 2 '), a better behavior is achieved in what would be a possible tearing of the coupling

or joint established by the clamp (10) mentioned, also ensuring greater tensile strength.

10 The union system described is susceptible of application and adaptability to other accessories, being compatible with other covers and assistants, whether made of metallic or plastic materials.

Finally say that the clamp (10) in each case, being

15 constituted in a metallic material, such as aluminum, it is easily deformable and adaptable to the required shape, requiring a minimum energy for its deformation, in addition to offering a minimum weight with respect to metallic materials such as steel and others.
