Description
Technical Field
[0001] This utility model relates to the field of hydraulic system connection technology, specifically a sealing joint for hydraulic hose assemblies. Background Technology
[0002] In hydraulic systems, the sealing joints of hydraulic hose assemblies are key components for the transmission and sealing of hydraulic media. Their performance directly affects the operational stability and safety of the entire hydraulic system. Currently, most common hydraulic hose assembly sealing joints on the market have a fixed angle structure, meaning that the connection angle between the joint body and the hydraulic hose and external hydraulic device is fixed and cannot be flexibly adjusted according to the actual installation scenario and work requirements.
[0003] Fixed-angle sealing joints have many limitations in practical applications: when the installation space of the hydraulic system is limited, the pipeline layout needs to be adjusted, or the direction of medium transmission needs to be changed during operation, fixed-angle sealing joints are often difficult to adapt. At this time, it is necessary to replace the joints with different angle specifications to meet the requirements. Frequent replacement of joints not only increases the cost of spare parts procurement, but also prolongs the installation and maintenance time of the system and reduces work efficiency.
[0004] In addition, some adjustable angle sealing joints have complex structural designs and cumbersome adjustment processes, requiring special tools to complete the angle adjustment, resulting in poor operation convenience. At the same time, the sealing performance and structural stability of these joints are often affected by unreasonable design of the adjustment mechanism. During long-term use, problems such as hydraulic medium leakage and angle locking failure are prone to occur, which may even lead to hydraulic system failure and safety hazards in severe cases. Utility Model Content
[0005] The purpose of this invention is to provide a sealing connector for hydraulic hose assemblies to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a connector body, a rubber hose fixed at the center of the connector body, a guide ring wrapped around the outer wall of the rubber hose, a fixed outer shell fixed on both sides of the guide ring, an operating inner ring inside the fixed outer shell, an operating component fixed on one side of the operating inner ring, multiple transmission components arrayed on the inner wall of the operating inner ring, a limit component rotatably connected to one end of each transmission component, a fixing rod fixed on both sides of the connector body, a rotating shaft fixed on the side of each fixing rod near the guide ring, and a telescopic snap-fit component fixed to the outer wall of the rotating shaft.
[0007] Preferably, the transmission assembly includes a clamping shaft, the clamping shaft array being distributed on the inner wall of the operating inner ring, and one end of the clamping shaft being rotatably connected to a connecting member.
[0008] Preferably, the limiting component includes a ratchet, which is rotatably connected to the inner wall of the fixed housing. A pin is rotatably connected to the side of the ratchet that contacts the fixed housing, and the ratchet is rotatably connected to the inner wall of the fixed housing through the pin.
[0009] Preferably, the telescopic snap-fit assembly includes a telescopic component, which is fixedly connected to the rotating shaft. An elastic element is sleeved on the outer wall of the telescopic component, and a contact is fixed at the end of the telescopic component away from the rotating shaft.
[0010] Preferably, one end of the connector is rotatably connected to the clamping shaft, and the other end is rotatably connected to the end of the ratchet away from the pin.
[0011] Preferably, the inner wall of the fixed housing is provided with a plurality of sliding grooves, which are matched with ratchet teeth.
[0012] Preferably, the contact is matched with a ratchet.
[0013] Compared with the prior art, the beneficial effects of this utility model are: Flexible angle adjustment and strong adaptability: Through the coordinated operation of the operating component, operating inner ring, transmission component, limiting component and telescopic snap-fit component, the angle of the connector body can be conveniently adjusted. When the angle needs to be adjusted, pressure is applied to both ends of the connector body to drive the contact to pass over the ratchet to complete the angle adjustment. Due to the ratchet shape restriction, the contact can only rotate in the specified direction, ensuring the stability of the adjustment process. When resetting, the ratchet can be released from the contact limit by pulling the operating component, so that the connector body can be quickly reset. This angle adjustment function enables the sealing connector to adapt to different installation scenarios and working requirements without replacing the entire sealing connector when changing the angle, which significantly improves its adaptability in complex hydraulic systems.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-5 This utility model provides a sealing joint technical solution for hydraulic hose assemblies: it includes a joint body 1, which serves as the basic load-bearing component of the entire sealing joint, providing installation reference and structural support for all other parts. It is the core carrier connecting the upstream and downstream of the hydraulic system, ensuring the stability and integrity of the overall structure, and providing a channel for the flow of hydraulic medium. A rubber hose 2 is fixed at the center of the joint body 1. The rubber hose 2 can bend and deform with the folding of the joint body 1, adapting to the position adjustment caused by the angle change. At the same time, thanks to its own sealing performance, it can still effectively prevent the leakage of hydraulic medium during bending, ensuring the continuity of hydraulic transmission.
[0018] The outer wall of the rubber hose 2 is wrapped with a guide ring 3, which serves to position and guide the rubber hose 2, constraining its position and preventing it from shifting or excessively rubbing during operation. A fixed housing 4 is fixed to both sides of the guide ring 3, providing a closed space for the internal components. The grooves on its inner wall are adapted to the ratchet 9, providing space for the ratchet 9's movement and ensuring its stability. An operating inner ring 5 is installed inside the fixed housing 4, linked to the operating component 6. When the operating component 6 is driven, the operating inner ring 5 rotates accordingly, transmitting the motion to subsequent components through the transmission assembly on the inner wall.
[0019] An operating component 6 is fixed to one side of the inner operating ring 5. When the operator applies a pulling force to itself, the operating component 6 can drive the inner operating ring 5 to rotate. Multiple transmission components are arrayed on the inner wall of the inner operating ring 5. The transmission components include clamping shafts 7, which are arrayed on the inner wall of the inner operating ring 5. The clamping shafts 7 can rotate with the inner operating ring 5, thereby driving the connecting component 8 to move, and thus converting the rotation of the inner operating ring 5 into a driving force for the ratchet 9.
[0020] One end of the clamping shaft 7 is rotatably connected to a connector 8. When the clamping shaft 7 moves, the connector 8 can pull the ratchet 9 to rotate, thereby manipulating the ratchet 9 to engage the contact 11. The other end of the connector 8 is rotatably connected to a limiting component, which includes the ratchet 9. The ratchet 9 is connected to the inner wall of the fixed housing 4 through a pin 10. The pin 10 provides a pivot point for the ratchet 9. Driven by the connector 8, the ratchet 9 can rotate around the pin 10, realizing the action of protruding or retracting from the inside of the fixed housing 4, thereby completing the limiting or unlocking of the contact 11.
[0021] A pin 10 is rotatably connected to the side of the ratchet 9 that contacts the fixed housing 4. The pin 10 allows the ratchet 9 to rotate around its own axis. Fixed rods 15 are fixed on both sides of the connector body 1. The fixed rods 15 can drive the telescopic snap-fit assembly to rotate. Through the cooperation of the contact 11 and the ratchet 9, the connector body 1 can be folded at a certain angle, thereby avoiding the need to replace the sealing connector when the connector angle needs to be changed. A rotating shaft 14 is fixed on the side of the fixed rod 15 near the guide ring 3. The rotating shaft 14 provides a rotation fulcrum for the telescopic component 12, ensuring that the telescopic component 12 can rotate flexibly to cooperate with the movement of the ratchet 9 and ensure the normal operation of the telescopic snap-fit assembly.
[0022] A telescopic snap-fit assembly is fixed to the outer wall of the rotating shaft 14. The telescopic snap-fit assembly includes a telescopic member 12, which is fixedly connected to the rotating shaft 14. The telescopic member 12 can adjust its own length. When the contact 11 contacts the ratchet 9 and is subjected to pressure, the telescopic member 12 can shorten its own length, thereby driving the contact 11 to pass over the ratchet 9, and thus causing the connector body 1 to adjust its own angle. An elastic element 13 is sleeved on the outer wall of the telescopic member 12. The elastic element 13 can help the telescopic member 12 to quickly return to its original position, thereby cooperating with the contact and the ratchet 9 to achieve the function of adjusting the angle of the connector body 1. The end of the telescopic member 12 away from the rotating shaft 14 is fixed with a contact 11, which matches the ratchet 9. When the ratchet 9 moves to the designated position, the contact and the ratchet 9 snap together to achieve the limit.
[0023] Working principle: When using a sealing connector for a hydraulic hose assembly, the operator first needs to fix one side of the connector body 1 to the hydraulic device, and then connect the other end of the connector body 1 to the hydraulic hose. When it is necessary to adjust the angle of the connector body 1, the operator needs to hold both ends of the connector body 1 and apply pressure to both ends of the connector body 1. At this time, the rotating shaft 14 rotates due to the pressure. When the rotating shaft 14 rotates, it drives the telescopic member 12 and the contact 11 to rotate. When the contact 11 rotates, it will contact the ratchet 9. When the contact 11 contacts the ratchet 9, the telescopic member 12 will shorten its own length due to the pressure, and at the same time drive the contact 11 to retract. At the same time, the elastic element 13 will retract and accumulate elastic potential energy. At this time, because the telescopic member 12 drives the contact 11 to retract, the contact 11 can pass the limit of multiple ratchet 9. At this time, the angle of the connector body 1 can be adjusted. At the same time, due to the shape of the ratchet 9 itself, the contact 11 can only rotate in the specified direction.
[0024] When the connector body 1 needs to be reset, the operator needs to pull the operating part 6. When the operating part 6 is rotated under pressure, it drives the inner operating ring 5 to rotate. When the inner operating ring 5 rotates, it drives the clamping shaft 7 and the connecting part 8 to rotate. When the connecting part 8 rotates, it pulls the ratchet 9, causing the ratchet 9 to rotate around the pin 10. At this time, the ratchet 9 will retract due to rotation. At this time, the contact 11 can perform the reset movement because it loses the limit of the ratchet 9.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
