A decrease in performance may be observed. In addition, in existing connection systems, a problem may arise between the hose and the connection body. Axis misalignments and alignment errors lead to uneven loading of locking elements. This negatively affects both connection security and sealing performance. It can have an impact. Additionally, a significant portion of existing systems have lock and release mechanisms. Since the mechanisms do not operate independently of each other, the connection can be accidentally severed. or it may be unintentionally separated during the move. Especially 15 such as twisting, pulling, or bending the hose in different directions during use The movements create additional loads on the locking elements, damaging the connection. This can reduce its reliability. In addition, a significant portion of the existing connectivity systems have both high connectivity requirements. 20 controlled systems that provide security and can be implemented quickly by the user. It is not possible to combine locking mechanisms within the same structure. Rotary locking action, safety latch and multi-stage sealing structures working together. However, solutions for the integrated mechanical coupling systems it works with are limited. is at that level.

Developed to create a controlled and leak-proof mechanical connection. Rotary bayonet locking, spring-loaded safety latch, and stepped sealing. a hose connection assembly (1) that brings together the fitting within the same mechanical structure It is related to. Within the scope of the invention, the hose connection assembly (1), mainly the main connection body (2), 20 hose connection fitting (3), body connection socket (4), bayonet locking system, safety locking system, sealing system, alignment system and internal flow that provides vacuum flow It consists of a structure. All of these subsystems are mechanically interconnected. It is designed to work seamlessly, ensuring a secure connection. It ensures both locking and long-term watertightness. Bottom 25 Mechanical force transfer between systems occurs along the connection. to prevent the concentration of axial, radial and torsional loads at a single point This arrangement allows the mechanical stresses generated during connection to be distributed across different structural elements. by distributing it to the elements in a controlled manner, both the locking mechanism and The sealing system is designed to operate stably for a long time. 30 The main connection body (2) constitutes the main supporting element of the connection assembly. Manufactured with integrated or fixed connection to hose fitting (3). It can be done. The bayonet locking system is located on the main connection body (2). 6 channels, housings for the safety mechanism, seal placement areas and guidance The elements are formed. The body connection socket (4) is the body of the vacuum cleaner. It is located on extension pipes or similar connecting elements and is the main connection. It is designed to work in conjunction with the main connection body (2). axial tensile forces, torsional moments and 5 that may occur during connection They are constructed with sufficient rigidity to carry impact loads, and the connection of structural loads It contributes to the even transfer of energy throughout the system. Bayonet locking system; bayonet locking channel (5), bayonet locking pin (6), bayonet steering ramp (7), front locking pocket (8), final locking pocket (9), locking It consists of a cam surface (10) and a locking stop surface (11). Hose connection 10 When the fitting (3) is inserted axially into the body connection socket (4), the bayonet Locking pins (6) enter the bayonet locking channels (5) and the user Bayonet steering ramps with short angular rotation movement applied by (7) It moves along the way. The pins (6) rotate after reaching the front locking pockets (8). As the movement continues, it settles into the final locking pockets (9), during which time the locking 15 The cam surface (10) creates axial compression between the connecting elements, thus forming the connection. It ensures a gap-free fit. Rotational movement, locking stop surface. (11) by limiting and obtaining the same locking position in each connection is provided. To prevent the locking mechanism from being unintentionally released, a bayonet system is used with 20 A safety mechanism that works together has been created. This mechanism is spring-assisted. safety claw (12), safety claw spring (13), safety spring bearing (14), safety claw guide (15), lock counter surface (16), release latch (17), latch axis (18), It consists of the latch return spring (19) and the latch housing (20). After the bayonet locking is complete, the safety tab (12), safety tab spring (13) 25 With its effect, the lock automatically sits on the counter surface (16) and the connection reverses. This prevents it from opening due to movement. The user must be able to disconnect the connection. The release latch (17) must be pressed by pressing the latch. This happens around the axis (18), retracting the safety latch (12) and the latch back Thanks to the return spring (19), the system can be automatically locked again when released. 30 It returns to its position. The latch housing (20) protects against external impacts and the entry of foreign objects. It reduces the negative effects on the mechanism. 7 The spring-supported safety claw (12) ensures the connection mechanism operates normally during its lifespan. safety claw spring (13) in such a way that it is in constant contact with the locking counter surface (16) It is kept under bias by the system. Thus, during use on the connection... the resulting vibrations, sudden tensile forces, torsional loads or impact effects This does not cause the safety tab (12) to retract spontaneously, mechanism 5 It maintains its locked position. The safety spring bearing (14) is in the axial direction of the spring. While ensuring stable operation, the safety claw guide (15) ensures that the safety claw It only allows movement in the defined direction. If force is applied to the release latch (17) by the user, the latch The latch rotates in a controlled manner around the axis (18) and this rotational movement is safe 10 The safety claw (12) moves away from the locking surface (16). The safety claw (12) returns When pulled, the bayonet locking mechanism can be released. connection with reverse rotational movement to be applied by the user. It can be resolved. When the user releases the latch, the latch return spring (19) is released. return the release latch (17) to its starting position and the safety tab (12) 15 It is getting ready to be locked again. The entire safety mechanism shall be protected within the latch housing (20) It is installed. The latch housing (20) protects the mechanical elements from external environmental factors. It helps protect against impacts, dust accumulation, and the entry of foreign objects. It also contributes to protecting the working axes of moving parts. 20 Thus, the operational accuracy of the safety mechanism is ensured during long-term use. Mechanical reliability is maintained. The safety mechanism is a second one that works in sequence with the bayonet locking mechanism. It forms a mechanical safety layer. Bayonet locking pins (6) form the final After reaching the locking pocket (9), the spring-loaded safety claw (12) automatically opens at 25 It intervenes and prevents the bayonet mechanism from rotating in the reverse direction. This Therefore, rotational movement alone is not sufficient to break the connection; First, the release latch (17) must be activated, then the safety tab (12) the separation of the lock from the counter surface (16) and only then the bayonet mechanism It needs to be reversed. This prevents the connection from opening unintentionally. 30 This is largely prevented, and a two-stage mechanical safety structure is created. Sealing is required to maintain high vacuum efficiency at the connection point. This system was created. This system consists of a primary sealing gasket (21), a secondary sealing gasket, and a primary sealing gasket (21). 8 gasket (22), stepped sealing fitting (23), labyrinth sealing channel (24), gasket It consists of a carrier bearing (25) and a gasket pressure ring (26). Main connection Stepwise sealing when the body (2) is fully locked into the body connection socket (4) The gaskets are controlled by means of the fitting (23), gasket pressure ring (26). compressing, the labyrinth seal channel (24) prevents possible air leaks from flowing through. 5 By extending its lifespan, it significantly reduces vacuum losses. Thus, it allows for long-term use. High sealing performance can be maintained even after this period. Primary sealing gasket (21), hose connection fitting (3) and housing connection socket (4) environmentally continuous contact occurs at the first contact line established between them This contact creates a negative pressure of 10 in the vacuum flow channel (37). This prevents leakage from the connection area to the external environment and ensures basic operation under normal working conditions. The sealing function is performed. The primary seal is the first of the fasteners. thanks to its elastic deformation, it can fill microscopic gaps that may form at the junction. It restricts air passage by filling the area. The secondary sealing gasket (22) works in series with the primary sealing gasket (21). It forms a leak-proof barrier. This can occur during the service life. material fatigue, manufacturing tolerances, temperature variations, or loss of elasticity As a result, small leakage paths that may form on the primary seal can lead to secondary sealing. It is closed by a gasket (22). Thus the system is not dependent on a single gasket element. It can provide high sealing reliability without any issues. 20 The stepped sealing fitting (23) forms on the gaskets as the connection is completed. It is designed to gradually increase the clamping force. The fitting geometry Thanks to its stepped structure, the compression force is not concentrated in a single area, the gasket It is distributed evenly along its circumference. Thus, the crushing of the seals is permanent. Deformation or premature wear is significantly reduced. 25 Labyrinth sealing channel (24) to prevent possible leaks in the connection area. It creates a nonlinear, elongated flow path for the air. Leaked air Because it has to change direction within this labyrinthine structure, the pressure loss increases, and The amount of air that can reach the outside environment is significantly reduced. Thus, especially This helps maintain suction performance at high vacuum levels. 30 The gasket carrier bearing (25), primary sealing gasket (21) and secondary sealing mechanical support that ensures the gasket (22) is positioned on the correct axis during assembly It forms the element. The gasket pressure ring (26) is completed when the connection is finished. 9 sealing by creating a predetermined compression force on the gaskets the elements remain stable within their housings throughout the operation This ensures that the seals do not rotate, curl, misalign, or develop axial misalignment. They are prevented from coming loose during operation. Mechanical alignment system 5 for reliable operation of the connection mechanism. This system was created as follows: mechanical alignment projection (27), alignment guide groove (28), rotary guide collar (29), torsion balancing ring (30), torque transmission surface (31), shock absorption collar (32), carrier reinforcement rib (33), linkage locking ring (34), locking position indicator (35), service removal opening (36), vacuum flow 10 consists of channel (37), flow guiding channel (38) and guide stop projection (39) It is coming. The mechanical alignment protrusion (27) fits into the body connection socket of the hose fitting (3). (4) during its initial placement it should be directed into the alignment guide groove (28) by ensuring that the connection is mounted only at the correct angular position. Thus, the bayonet locking pins (6) fit into the bayonet locking channels (5) 15 This ensures that the device enters the assembly without errors, and prevents axial misalignments that may occur during assembly. Incorrect positioning is prevented. Rotary guide collar (29), hose connection fitting (3) and main connection body (2) It helps to achieve controlled rotational movement between them, Bayonet locking 20 reduces friction forces generated during connection. It ensures that the mechanism works more smoothly. Torsion balance ring (30) this includes twisting, bending, or pulling the hose in different directions during use. By distributing the resulting torsional stresses over a wide surface, it reduces load concentration. It reduces. Torque transmission surface (31), bayonet 25 of the rotational force applied by the user It is designed to allow the transmission to the interlocking system in a controlled manner. Thus, the force applied during the locking process is only through the bayonet locking pins. (6) does not focus on the main connection body (2) and the hose connection fitting (3) They are distributed evenly among them. This reduces mechanical wear. and also contributes to maintaining locking performance during long-term use. 30 It provides. Sudden impact loads that may occur in the connection area can have a negative effect on the mechanism. In order to prevent the formation of impact, an impact damping ring (32) is used. Damping ring (32) elastically dampes sudden load changes between connecting elements. by absorbing both the locking system and the sealing elements. It protects. The carrier reinforcement ribs formed on the main connection body (2) (33) increases the rigidity of the body, bending that occurs during connection and It ensures that torsional loads are transferred more homogeneously. 5 Connection locking ring (34), main connection body (2) and hose connection fitting (3) By providing additional structural integrity between the connecting elements in the axial direction. This prevents them from separating from each other. The locking position indicator (35) The user is shown visually and / or mechanically the position where the connection is fully locked. It is designed to report this. Thus, 10 from the incomplete locking of the connection. This prevents potential usage errors. The lock position indicator (35) informs the user that the connection is fully completed. can communicate through visual cues, mechanical click sensations, or similar feedback methods. It can be configured in this way. Thus, the user can ensure a secure connection. It can detect that it's locked without performing any additional checks. 15 Service removal opening (36), safety when maintenance or parts replacement is required. It was created to provide controlled access to the mechanism. This opening Thanks to this, the connection mechanism can be disassembled without damaging the mechanical elements, and It can be reassembled. This simplifies maintenance procedures and product servicing. Its lifespan is also being increased. 20 The vacuum flow channel (37) transmits the suction force created by the vacuum cleaner along the hose. It forms the main flow path that ensures uninterrupted transmission. Vacuum flow Flow guiding channel (38) created depending on channel (37) of air flow sudden It is designed to reduce turbulence caused by changes in cross-section. It contributes to a more regular flow. Thus, both suction 25 performance is maintained and potential flow losses in the connection area are minimized. is being reduced. The guide stop projection (39) controls the rotational movement of the bayonet locking mechanism. It is positioned to keep it within predetermined angular limits. Thus, the bayonet locking pins (6) exceed the final locking pocket (9) or exceed 30 This prevents mechanical elements from being stressed due to rotation. At the same time, each During the assembly process, it is ensured that the connection terminates in the same locking position, thus both 11 a repeatable operating characteristic in terms of both leak tightness and mechanical safety is obtained. The alignment guide groove (28) with the mechanical alignment protrusion (27) ensures that the connection is only It not only ensures that it moves along the correct axis and in the correct angular position, but also The bayonet locking pins (6) move from the same starting point in each assembly operation. This makes it possible to perform the geometric operation of the locking mechanism. The conditions are maintained with each use, preventing uneven wear and tear. It is being passed. The rotary guide collar (29) during the rotational movement of the hose connection fitting (3) By limiting the deviation from the axial direction, controlled rotational movement is achieved. 10 This structure reduces friction forces that may occur during connection. and a lower level of rotational force that needs to be applied by the user. It contributes to its continued existence. Torsion balancing ring (30) prevents torsion from occurring on the hose during use. It distributes torsional moments homogeneously around the connection circumference. Torque transmission 15 The surface (31) ensures that these forces are transferred to the main connecting body (2) in a controlled manner. by ensuring that the loads are concentrated only on the bayonet locking pins (6) This prevents fatigue, thus increasing the fatigue life of the fasteners. Impact damping collar (32) protects the connection from sudden pulling, impact or falling. It elastically absorbs the transmitted dynamic loads. The load-bearing reinforcement ribs are 20. (33) increasing the rigidity of the main connection body (2) bending that occurs along the connection It reduces their stresses. The connection locking ring (34) reduces the axial stress of the connection. It provides additional mechanical support that prevents it from opening in the correct direction. The lock position indicator (35) visually informs the user that the connection is fully locked. It can be configured to provide auditory or tactile feedback. Service 25 The disassembly opening (36) is used to secure the safety mechanism during maintenance and repair operations. Controlled access allows fasteners to be removed without damage. It provides. The bayonet locking system, safety mechanism, and sealing system described above. and the alignment system work together as complementary mechanical subsystems. 30 It is working. Thanks to the coordinated operation of these subsystems, the connection is established. creation, secure preservation and, if necessary, controlled release This is possible. Below is a study illustrating a preferred application example of the invention. 12 The principle is explained in detail. The application example described illustrates the invention. This does not limit its scope, and different applications using the same technical principles are also available. It is considered within the scope of the invention. During use, the user attaches the hose connector (3) to the body connector housing (4) After positioning it axially, it applies a short rotational movement. This is 5 bayonet locking pins (6), bayonet steering ramps (7) during movement It moves along the way until it reaches the final locking pockets (9), the safety tab (12) automatically The lock sits on the counter surface (16) and the connection is securely locked. When the connection needs to be disconnected, the user simply needs to press the release latch (17) by pressing and pulling back the safety tab (12) and then a short turn in the opposite direction 10 By performing the movement, it is able to release the connection in a controlled manner. Thanks to this structure, the invention offers high mechanical strength and is resistant to unintentional detachment. Locking mechanism, low air leakage, long service life, easy assembly and disassembly, high suction. Its efficiency allows it to be adapted to different vacuum cleaning systems thanks to its modular hose connection. It offers a solution. This integrated mechanical structure, bayonet locking mechanism, 15 A safety claw, multi-stage sealing system, and controlled load distribution all in one. by assembling them in a connection system, technically according to existing hose connection systems. and provides a functional advantage. The invention includes the main connection body (2), hose connection fitting (3) and body connection. The housing (4) can be produced as a single piece or by combining multiple pieces; 20 injection molding, metalworking, casting, additive manufacturing or similar production It can also be manufactured using engineering methods. The material to be used; plastic, metal alloy, composite material or hybrid materials using a combination of these. The structures can be selected from among the available options according to the application requirements. Bayonet locking channels (5) and bayonet locking pins (6) allow for different locking angles of 25°. It can be designed to have the slope of bayonet steering ramps (7). angles, depths of the front locking pockets (8), geometries of the final locking pockets (9) with the slope characteristics of the locking cam surfaces (10) according to the application They can be modified, and all of these modifications alter the fundamental working principle of the invention. It can be adapted to different usage needs without modification. 30 The safety mechanism consists of a spring-supported safety claw (12), safety claw spring. (13), safety spring bearing (14), safety claw guide (15), lock strike plate (16), release latch (17), latch axis (18), latch return spring (19) and latch 13 The housing (20) can be produced in different sizes, forms and spring characteristics. Free The release latch (17) should have different geometries to improve user ergonomics. Or it can be controlled from different regions. The primary seal gasket (21) and secondary seal gasket used within the sealing system sealing gasket (22), elastomer, silicone, thermoplastic elastomer or similar 5 It can be produced from sealing materials. The stepped sealing fitting (23) geometry, length and cross-section of the labyrinth seal channel (24), gasket carrier The arrangement of the bearing (25) and the compression force of the gasket pressure ring (26) are different. It can be adjusted to suit the vacuum levels. The mechanical alignment protrusion (27) and the alignment guide groove (28) allow the connection to be made only one 10 It can be designed to be mounted in an angular position, or in different They can also be created in the form of multiple alignment structures that allow for angular positions. Rotary guide collar (29), torsional balancing ring (30) and torque transmission surface (31) By working together, they can control the mechanical loads transmitted to the hose during use. It distributes and reduces the fatigue effects that may occur on the connecting elements. 15 Impact damping collar (32), carrier reinforcement rib (33) and connection locking ring (34), in order to increase the mechanical strength of the connection area, different geometries It can be created. Locking position indicator (35), visual marking, color change, to provide mechanical indication or tactile mechanical feedback It is applicable. 20 Service removal opening (36) in locations that will facilitate maintenance operations. It can be adjusted without the need to disassemble the entire mechanism. It only allows access to the safety mechanism. Vacuum flow channel (37) and flow guiding channel (38), with different diameters and different flow cross-sections It can be adjusted, thus adapting to vacuum systems with different suction capacities. 25 It can provide. Guide stop projection (39) the final position of the bayonet locking mechanism It acts as a reference element that mechanically determines the connection. By ensuring it stops at the same locking point each time it is used, it provides both mechanical safety. and also stabilizes the sealing performance. 30 The invention is not intended solely for use in household vacuum cleaners; central vacuum systems, industrial vacuum devices, wet-dry vacuum cleaners, professional cleaning equipment and similar flow systems operating on the vacuum principle 14 It offers a mechanical connection solution that can be implemented. Furthermore, the connection... the dimensions, geometries, material structures, spring characteristics, and seals of its components Types, locking angles and mechanical arrangements vary according to the application area. It can be modified, and these modifications may alter the fundamental operating principle of the invention. It can be done without separation. 5 During the operation of the invention, the user can connect the hose connector (3), body connector It brings it closer to its housing (4) in the axial direction. During this time, the mechanical alignment protrusion (27) enters the alignment guide groove (28) so that the connection is only the correct angular. This allows the bayonet locking pins (6) to move in position. It automatically aligns with the starting points of the locking channels (5) and 10 No additional guidance is required from the user. The opposite of the mechanical alignment protrusion (27) and the alignment guide groove (28) contact allows the hose fitting (3) to advance only in the correct angular position. Thus, the bayonet locking pins (6) fit into the bayonet locking channels (5) 15 (This refers to entering at an oblique angle, hitting channel surfaces, or experiencing mechanical stress during installation) This prevents the formation of a barrier. At the same time, the fasteners must be in place during each assembly process. by ensuring that the locking mechanism operates from the same reference position. Repeatability is increased. After the connection fitting (3) is inserted into the body connection socket (4) in the axial direction Then a limited rotational movement is applied by the user. This rotational movement is 20 during bayonet locking pins (6), bayonet routing ramps (7) progressing, thanks to the inclined structure of the ramps, the hose connection fitting (3) and the body The connection sockets (4) approach each other axially. Thus, the connection A controlled compressive force is generated between the elements. Thanks to the inclined geometry of the bayonet steering ramps (7), the user can use 25 a portion of the applied rotational motion is converted into axial progression motion. It is converted. Thus, the hose connection fitting (3) and the body connection socket (4) approaching each other in a controlled manner, mechanical connection between the fasteners The voids are eliminated and the required pre-tightening force of the sealing elements is applied. It is generated automatically. Thanks to this cam effect, a high clamping force of 30 is achieved. No additional fasteners are needed to create it. With the continuation of the rotational movement, the bayonet locking pins (6) pre-lock Passing through the pockets (8), it reaches the final locking pockets (9). Simultaneously locking cam surfaces (10) press the connecting elements towards each other, thus forming the connection. It ensures a gap-free fit. Rotational movement, locking stop surface. It is limited by the guide stop projection (39) which works together with (11) and This ensures the same locking position is achieved in every assembly process. Bayonet locking. The angled contact surfaces used in the mechanism ensure connection 5 as the locking process is complete. The elements are arranged so that they are axially closer to each other. Thus Limited rotational movement applied by the user, as well as automatic connection. It creates a cam effect that causes the skin to tighten. With the bayonet locking pins (6) fully seated in their final locking pockets (9) The rotational movement of the link is mechanically limited. This 10 limiting, locking stop surface (11) and guide stop projection (39) This is achieved through their collaborative work, and potential problems due to excessive rotation may occur. Mechanical stresses are prevented. Thus, both the bayonet mechanism and... The sealing system must operate under the same working conditions during each use. is provided. 15 When the bayonet mechanism reaches its final position, the spring-loaded safety claw (12), The safety claw spring (13) automatically locks the counter surface (16) It is located there. Thus, the user can access a second safety mechanism without performing any additional actions. This also activates the lock. Unless the release latch (17) is pressed The safety tab (12) prevents the bayonet mechanism from rotating in the reverse direction. It prevents the connection from being unintentionally severed. Therefore, only a rotational movement in the opposite direction is applied to break the connection. It is not sufficient to first operate the release latch (17), safety separation of the tab (12) from the locking surface (16) and then the bayonet The mechanism needs to be rotated in the reverse direction in a controlled manner. These two 25 The multi-stage mechanical safety structure prevents unintentional connection issues during use. It significantly reduces their chances of leaving. When the safety claw (12) is automatically engaged, the safety claw spring (13) stores energy compressed inside the safety spring bearing (14) and this Thanks to the energy, the safety claw (12) continuously moves towards the locking counter surface (16) 30 is suppressed. This pre-tension effect prevents the connection from vibrating, impacting, or pulling suddenly. Even when subjected to forces, the safety claw does not involuntarily retract. It increases mechanical safety by preventing it from being pulled. 16 Pulling, pushing, twisting, or moving the hose in different directions during use The mechanical loads resulting from its bending are primarily on the rotary guide collar (29) It is met by. Torsion balancing ring (30), torsion from the hose While distributing the moments circumferentially, the torque transmission surface (31) distributes the rotational forces to the main It transmits homogeneously along the connecting body (2). The carrier reinforcement ribs 5 (33) reduces deformations under high load by increasing the body rigidity. Torsion balancing ring (30) and torque transmission surface (31), connection via hose. It distributes the rotational moments transmitted to the mechanism over a wide contact area. Thus The loads are not concentrated only on the bayonet locking pins (6), the main connection body (2), connection locking ring (34) and carrier reinforcement ribs (33) by 10 They are carried jointly. This structure reduces mechanical fatigue, extending the life of the connection system. This contributes to its reliable operation over time. In case the connection is exposed to external impacts, the shock absorbing ring (32), It elastically dampens the sudden forces that occur and these loads are directly transferred to the bayonet. This prevents the transmission to the locking mechanism or safety system. Thus, both 15 This extends the lifespan of mechanical parts and improves the reliability of the connection. It is protected. The shock absorbing ring (32) absorbs the load increase in case of sudden load application to the connection. By reducing its speed, the safety mechanism, bayonet locking system, and sealing mechanism It reduces peak stresses that may occur on the elements. Thus, mechanical 20 The fatigue life of the components is increased and the repeated use performance of the connection is improved. It is protected. When a vacuum is created, the airflow moves along the vacuum flow channel (37), flow The flow direction is regulated thanks to the routing channel (38). During this time, the primary sealing gasket (21) and secondary sealing gasket (22), staged sealing 25 The fitting (23) is compressed in a controlled manner by the gasket carrier bearing (25) and the gasket The pressure ring (26) keeps the working position of the seals fixed. Labyrinth sealing channel (24) creates an extended flow path for possible leakage air, thus reducing vacuum losses. It reduces it significantly. As the vacuum level increases, the hose connection fitting (3) and the body connection socket (4) 30 The contact force between them also increases, and this situation is with the primary sealing gasket (21) more effective contact of the secondary sealing gasket (22) with the connection surface 17 Thus, the system utilizes the vacuum force generated during operation. It transforms the sealing performance into a self-supporting structure. Flow direction channel (38) prevents sudden changes in the direction of the airflow at the connection area. by limiting turbulence formation and more vacuum flow channel (37) It creates a stable flow profile. Thus, the suction performance improves by 5. System efficiency is increased by reducing fluctuations. When the connection is fully locked, the bayonet locking mechanism... The axial compression force generated is transmitted through the stepped sealing fitting (23). The transfer is transmitted to the sealing elements. Simultaneously, the safety mechanism is engaged. Thanks to this, the fasteners are prevented from loosening during operation and 10 The clamping force generated is maintained throughout the service life. Thus, the locking mechanism... The system and the sealing system are an integrated structure that mechanically supports each other. It constitutes. Through the locking position indicator (35) that the connection is completed correctly This is understandable by the user. Thus, missing locking or faulty assembly 15 The possibility is reduced. If necessary, safety is ensured by using the service removal opening (36). The mechanism is accessible and the connecting elements are controlled. It can be disassembled. When the connection needs to be disconnected, the user must first press the release latch (17) By pressing, it separates the spring-assisted safety claw (12) from the locking strike surface (16). 20 Then a short reverse rotation is applied to the hose fitting (3), bayonet locking pins (6) from the final locking pocket (9) respectively, from the front locking pocket (8) and passing through the bayonet guiding ramp (7) into the bayonet locking channel (5) entrance It reaches the part. In the final stage, the hose connection fitting (3) is in the axial direction. It is pulled away from the body connection socket (4). 25 The force applied to the release latch (17) during the disconnection of the link When the latch return spring (19) disappears, the release latch starts. It returns to its position. At the same time, the spring is activated by the safety claw spring (13). The supported safety claw (12) moves towards the locking counter surface (16) again. It returns to its starting position. Thus, the connecting elements come together again. 30 When brought in, safety requires no additional adjustment or installation procedures. The mechanism automatically becomes ready to restart. 18 During normal use, the hose connection assembly (1) is connected to the hose by the user. mechanical under applied axial tensile, compressive, torsional and bending forces It operates in a way that maintains its integrity. These loads are supported by the bayonet locking mechanism. The load is shared in a controlled manner between the safety system and load distribution elements. Excessive stress on any single mechanical element is prevented. 5 Moving the vacuum cleaner across the floor during use can damage the hose. can occur if it gets caught on furniture or is subjected to sudden pulling forces. Dynamic loads are primarily absorbed by the shock absorbing ring (32), then torsion balancing ring (30), torque transmission surface (31) and carrier reinforcement It is distributed along the connecting body through its ribs (33). Thus, the connection 10 This prevents sudden stress concentrations from occurring at that point. Natural wear and tear that may occur during prolonged use, the connection It is provided in a way that does not disrupt the working principle of the mechanism. Bayonet The locking system, safety mechanism, and sealing system are independent of each other. Since it continues to perform its functions, limited wear on a single element is possible. Connection 15 This does not lead to a complete loss of security. Repeated loading and unloading cycles occurring within the coupling system. During mechanical loads, bayonet locking system, safety mechanism, torsion balancing ring (30), torque transmission surface (31) and carrier reinforcement ribs (33) It is shared between them. Thus, the continuous stress on a given mechanical element is 20 This prevents the accumulation of deposits and increases the fatigue life of the connection system.
