1 TARIFF HOSE WITH IMPROVED NIPPLE STRUCTURE PROVIDING THREE-WAY SEALING. CONNECTION ASSEMBLY Technical Area The invention describes the connection of flexible hoses used for fluid transmission to installation components. It relates to a hose connection assembly that provides a connection. The invention, in particular, allows for three-part reductions in hose and seal areas thanks to modifications made to the nipple structure. A hose that provides improved sealing and connection strength by creating a directional closure. 10 It relates to the connection device. State of the Art Today, there are 15 different types of flexible hoses used for connecting them to each other or to plumbing components. Hose connection fittings are used. These fittings generally include nuts, nipples, and compression bushings. It consists of gaskets and similar sealing elements and mechanically holds the hose in place. and aims to prevent the fluid from leaking into the external environment. In existing systems, the hose Solutions based on placing the nipple over the screw and tightening it with a nut are common. However, in such systems, sealing is usually achieved through single or double-sided contact surfaces. 20 This is ensured through the positioning of the gaskets and the assembly of the clamping elements. It is susceptible to operator errors. Indeed, the tightening operation performed by the user, especially Metal or braided hoses require high force, which can lead to hose deformation. This can lead to leaks due to insufficient tightening or damage to parts due to overtightening. Within this scope, one of the known systems is the hose connection with application number TR2020 05735. the assembly, including the nut, clamping bushing and nipple elements in which the hose is positioned. It offers a structure that includes a gasket to ensure leak-proofness. In the application in question, the hose... The aim is to fit the nut into the gasket without crushing it and to ensure a seal. However, in this structure, sealing is primarily one-way or at limited contact surfaces. 30 This occurs in cases where fasteners are subjected to impact or have tolerance differences. It is assessed that the sealing performance is not maintained at an adequate level. Furthermore, the structure... Due to the lack of a more rigid grip, loosening or leakage may occur during prolonged use. The risk remains. 35 2 Another existing technical example is US6860520B2, titled "Hose coupling assembly". A patent document can be provided. This application describes the fitting of the hose over the nipple and with a socket. A system based on compression is described. The structure includes hoses, nipples, and sockets. sealing is achieved by compressing them between the layers, and also a sealing element (annular sealing) The gasket function is supported by using (member). However, in this system, 5 Sealing depends largely on the compressive force, and the decrease or loss of this force over time... It is stated that leaks may occur if the hose is displaced under high pressure. Therefore, this solution is durable and highly resistant, especially under high pressure and dynamic loads. It cannot provide a directional seal. In addition, patent number EP4279788B1, titled "Push-fitting," describes how a pipe or hose can be fitted with a... A quick-connect system is described that allows the connector to be attached by being pushed into the housing. The system includes toothed grip rings and sealing elements that grip the outer surface of the pipe. They work together. These structures provide ease of assembly, but leak-proofness is essential. This is achieved through contact between ring-type gaskets and the pipe surface. In this case, 15 Sealing occurs in a specific direction, particularly applied in the axial direction. the stability and watertightness of the system against forces or impacts to the fastener can be negatively affected. Also, instead of a multifaceted closure, it involves limited contact areas. This approach can lead to a decline in performance in the long run. Consequently, in hose connection assemblies used in current technology, leak tightness is mostly... where the connection is provided from only one or limited directions, the rigidity of the connection is insufficient, and there are assembly errors. It is observed that open structures are present. Therefore, both sealing performance is improved and A new hose connection assembly is needed that enhances connection security by providing versatile closure. It is heard. 25 Brief Description of the Invention The present invention meets the aforementioned requirements while eliminating all disadvantages.

The hose connection assembly (100) which enables connection to the plumbing elements is only the subject of more as an example to ensure a better understanding and without creating any limiting effects It is explained. The hose connection device (100), the subject of the invention shown in Figure-1, is intended for fluid transmission. The flexible hoses used (110) are safe, easy to assemble and have high leak tightness. a connector that allows connections to be made to each other or to installation elements in such a way as to provide a connection. It is a structure. Hose connection assembly (100), hose (110), nipple / fitting (120), nipple lower extension (121), By combining nipple chamfer (122), ring (130), gasket (140) and nut (150) elements geometric changes are made, especially in the nipple / fitting (120) structure. 10 thanks to which the hose (110) will be gripped in three directions and the sealing will be improved. It is designed in this way. The hose (110) is the main element through which the fluid passes and is the connection point between the two parts of the system that are to be connected. It provides fluid transmission between the points. The hose (110) is structurally flexible, By pushing the nipple / fitting (120) into the system and tightening it with the help of the nut (150), 15 It is located. The nipple / fitting (120) shown in Figure-2 is the basic connection in the hose connection assembly (100). It is the element that mechanically holds the hose (110) and at the same time ensures the safe flow of fluid. It ensures leak-proof transmission. Nipple / fitting (120) in the part that enters the hose (110) 20 It is positioned and has a structure that supports the hose from the inside and increases its shape stability. The nipple sub-extension (121) formed in an integrated manner on the aforementioned nipple / fitting (120), by contacting the inner surface of the hose (110) from below, the hose is not only circumferential but also This allows for gripping over a wider area over time, thereby increasing the contact surface area. In addition, the nipple bevel (122) is 25 on the nipple / fitting (120) of the hose (110). It creates an inclined surface that allows for a gradual and controlled passage, thus facilitating assembly. While ease of use is ensured, damage to the hose is prevented. Nipple / fitting (120), nipple lower extension When (121) and nipple bevel (122) are considered together, the surfaces in contact with the hose (110) by increasing the contact, ensuring a more homogeneous distribution of contact and three-dimensional wrapping of the hose Sealing performance and connection rigidity are significantly improved. 30 The lower extension of the nipple (121) continues integrally at the bottom of the nipple / fitting (120) element and It is a structure that makes direct contact with the inner surface of the hose (110) and is inside the hose connection assembly (100). Nipple lower extension (121), is a critical element that improves sealing and mechanical adhesion performance. In addition to compressing the hose (110) circumferentially from the top and side areas, the bottom 35 It is positioned in such a way as to provide support from the region and with hose (110) This significantly expands the contact area between the nipple / fitting (120). This expanded contact 6 the area to ensure that the hose (110) sits more evenly and homogeneously on the nipple / fitting (120). It ensures and prevents the formation of local pressure points, thereby preventing hose deformation. It reduces and increases the continuity of the sealing surface. In addition, the nipple lower extension (121), By creating a counter surface at the bottom of the hose (110), the hose is only radial within the system. not only that, but it also allows for a multifaceted embrace, thus providing a three-way grip. 5 and by creating a wrapping effect, it prevents the fluid from leaking to the outside environment, making it more stable and It contributes to achieving a durable sealing structure. The nipple bevel (122) is located at the end of the nipple / fitting (120) element where it connects to the hose (110) and It is a sloping surface designed to facilitate the entry of the hose (110). Nipple bevel (122) 10 During assembly, the hose (110) forms the first contact area with the nipple / fitting (120). and a stepped layout which prevents the hose (110) from coming into contact with sharp edges. This angled structure ensures that the hose (110) does not apply sudden force to the nipple / fitting (120). It can be advanced without being applied or strained, thus making the assembly process more controlled and safer. It is carried out in this way. In addition, nipple bevel (122) can be formed on the inner surface of the hose (110) 15 It helps maintain the shape of the hose by reducing the risk of wear, tear, or deformation. In addition, the nipple bevel (122) is located on the nipple / fitting (120) of the hose (110). By ensuring proper alignment, it minimizes placement errors that may occur during assembly. by creating a suitable starting position for the hose (110) to contact the lower nipple extension (121) This helps to achieve a more homogeneous pressure distribution in the subsequent compression stage. 20 is happening. The ring (130) supports the sealing inside the hose connection assembly (100) and the connection It is an auxiliary element that increases mechanical stability. Ring (130) around nipple / fitting (120) and By positioning it between the hose (110) and other fittings, the 25 within the system It acts as an intermediate support, maintaining the relative position of the parts. This structure... Thanks to the ring (130), the contact between the hose (110) and the nipple / fitting (120) is more balanced. This contributes to the maintenance of the system and, in particular, to the forces generated after the squeezing process. It helps to distribute homogeneously. Also, the ring (130) comes into contact with the hose (110). By minimizing micro-movements that may occur on the surfaces, it prevents the connection from loosening and 30 This helps maintain the system's sealing performance during long-term use. However, the ring (130) shown in figure-3 works together with the gasket (140) to provide sealing. It helps the elements remain fixed in place and protects them from external factors, vibration or pressure. It helps maintain the integrity of the connection in the face of changes. 35 The gasket (140) prevents the fluid from leaking out of the hose connection assembly (100). and is the essential sealing element that ensures the safe operation of the system, being the most critical part of the connection. 7 It is one of the elements. The gasket (140) is in the contact area between the nipple / fitting (120) and the hose (110). positioned and tightened axially and radially during the tightening operation performed with the nut (5). elastic material that deforms and fills the gaps due to forces applied in one direction. It forms a barrier. Thanks to this elastic structure, the gasket (140) is connected to the hose (110) and nipple / fitting. (120) tolerates surface irregularities and voids that may occur at the micro level. By closing it, it increases the seal. In addition, the gasket (140) works together with the ring (130) to improve the system. It remains stable and undisturbed under internal pressure changes, vibrations, and external influences. This helps maintain the sealing performance during long-term use. With the gasket (140), the contact force between the hose (110) and the nipple / fitting (120) is more balanced. By helping to distribute it, it both reduces the risk of deformation of the hose (110) and 10 It increases the overall strength and reliability of the connection. The nut (150) performs the assembly process inside the hose connection assembly (100), tightening which creates its force and securely fastens the hose (110) to another connecting element. It is the main mechanical component that provides. The nut (150) has a threaded structure compatible with the nipple / fitting (120). having and being placed around the nipple / fitting (120) inside the hose connection assembly (100) It is positioned in such a way as to form a screw connection with it. During assembly, the nut (150) As it is tightened by turning, the hose (110) is advanced axially over the nipple / fitting (120). and as a result of this movement the hose (110), nipple / fitting (120), nipple lower extension (121) and nipple bevel (122) establishes a tighter contact. This compression effect is not only a mechanical grip 20 not only does it not provide, but it also applies pressure on the gasket (140) and the gasket (140) It increases its deformation and contributes to raising the level of sealing. Furthermore... The nut (150) transmits the applied tightening force to the system elements in a controlled manner, thus connecting them. It creates a homogeneous pressure distribution in the region and the hose (110) uncontrollably This prevents crushing while ensuring a sufficiently tight connection. This 25 In this way, the nut (150) ensures both easy and repeatable assembly and This helps the connection remain stable and free from loosening during prolonged use. When assembling the hose connection assembly (100), first place the hose (110) onto the nipple / fitting (120). It is inserted by pushing. At this stage, thanks to the nipple bevel (122), the hose (110) is inserted without strain and damage. 30 It is passed over the nipple / fitting (120) without seeing it. As the hose (110) advances, the lower extension of the nipple (121) It makes contact with the inner surface of the hose and begins to grip the bottom of the hose. Hose (110) When the nipple / fitting (120) is fully seated, the end of the hose is fully connected to the nipple / fitting (120). They are positioned so that they will make contact. 35 Then the gasket (140) is placed in its appropriate slot and the sealing elements together with the ring (130) are installed. It is prepared. The nut (150) is placed over the nipple / fitting (120) and the tightening process is started. The nut 8 (150) As it is tightened, the hose (110) is pressed onto the nipple / fitting (120) and with this pressure A versatile connection between the hose (110), nipple / fitting (120), nipple lower extension (121) and nipple chamfer (122) Contact is made. Thanks to this contact, the hose (110) is connected from three different angles: from the top, from the side and from the bottom. It wraps around from all directions, thus achieving a strong mechanical grip. When the tightening process is complete, the ring (130) and gasket (140) shown in figure-5 come into play. It prevents the fluid from leaking into the external environment. Thanks to the nipple lower extension (121), the hose (110) bottom Because it is also supported from this side, the connection becomes more rigid and its resistance to external influences increases. Thanks to this design, the hose connection assembly (100) is both easy to assemble and long-lasting. It operates in a way that provides high sealing and mechanical strength during use. 10
