Description

Technical Field

[0001] This utility model belongs to the field of hydraulic technology, and specifically relates to a hydraulic connector. Background Technology

[0002] Existing hydraulic connectors consist of a male and a female connector, with each connector connecting to two independent pipelines. Pipeline connection is achieved by mating the male and female connectors together. However, existing mating methods mostly use direct plugging, lacking effective guiding and positioning structures. This makes them prone to misalignment and displacement during the mating process, resulting in difficult operation, low efficiency, and the risk of seal failure or insufficient connection strength. Consequently, they fail to meet the operational requirements for rapid and reliable connections in complex underwater environments.

[0003] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a liquid connector. Utility Model Content

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0034] Reference Figures 1-4 As shown, the liquid connector in one embodiment of this utility model may include: a female connector 1, a male connector 2, and a guide sleeve 3. One end of the male connector 2 is installed with the female connector 1; the guide sleeve 3 is fitted onto the male connector 2, forming a receiving space 30 between the guide sleeve 3 and the male connector 2. The female connector 1 is at least partially disposed within this receiving space 30. The inner wall of the end of the guide sleeve 3 facing the female connector 1 has a guide surface 31. This guide surface 31 can be any of a conical surface, a spherical surface, or a parabolic surface. Specifically, in this embodiment, the guide surface 31 is an inclined surface or a chamfer, and its diameter gradually increases from the end of the guide sleeve 3 facing the gasket 5 towards the end away from the gasket 5. According to this design, during the installation of the male connector 2 and the female connector 1, the axis of the male connector 2 and the axis of the female connector 1 can be automatically aligned under the guidance of the guide surface 31, making installation more time-saving and convenient.

[0035] This application, through the design of the guide sleeve 3, effectively overcomes the problems of misalignment and displacement that easily occur during underwater docking of male connector 2 and female connector 1, significantly improving the convenience and success rate of docking operations. It not only ensures a fast and labor-saving docking process but also guarantees the sealing reliability and structural stability after docking, meeting the stringent requirements of efficient and reliable connections in complex underwater environments.

[0036] Specifically, in order to facilitate the formation of the receiving space 30, so as to receive the female connector 1, refer to Figures 2-4 As shown, the male connector 2 in this embodiment may include a main body 21, a mounting part 22 that is installed with the female connector 1, and an adjustment part 23 disposed on the end of the main body 21 away from the mounting part 22. The outer diameter of the main body 21 may be larger than the outer diameter of the adjustment part 23. The outer wall of the male connector 2 is provided with an adjustment ring surface 24 connecting the main body 21 and the adjustment part 23. In order to guide the installation of the male connector 2 and the female connector 1, the outer diameter of the main body 21 in this embodiment may be larger than the outer diameter of the mounting part 22. The guide sleeve 3 may be fitted over the main body 21, and a receiving space 30 is formed between the guide sleeve 3 and the mounting part 22. The female connector 1 is at least partially installed in the receiving space 30.

[0037] Preferably, refer to Figure 3 , Figure 4 As shown, in this embodiment, the guide sleeve 3 is fixedly installed to the male connector 2 by a positioning pin 4. Specifically, the positioning pin 4 is arranged radially and inserted into the main body 21 of the male connector 2 and the guide sleeve 3 respectively. The design of the positioning pin 4 prevents relative rotation between the two.

[0038] Reference Figure 5 As shown, the adjusting ring surface 24 in this embodiment can be a convex arc surface protruding outwards; the liquid connector also includes a gasket 5 sleeved on the adjusting part 23. Since the outer diameter of the main body 21 can be larger than the outer diameter of the adjusting part 23, the gasket 5 can be prevented from sliding onto the main body 21, improving the rigidity and stability of the locking between the gasket 5 and the male connector 2. The inner wall of the gasket 5 is provided with a mating surface 51 that cooperates with the adjusting ring surface 24; the gasket 5 has a first state and a second state; in the first state, the mating surface 51 abuts against the adjusting ring surface 24 at a first abutting position, so that the male connector 2 maintains a first angle; in the second state, the mating surface 51 abuts against the adjusting ring surface 24 at a second abutting position different from the first abutting position, so that the male connector 2 maintains a second angle different from the first angle. The gasket 5 is detachably installed on the male connector 2. By changing the relative position between the gasket 5 and the male connector 2, the abutting position between the adjusting ring surface 24 and the mating surface 51 is changed, thereby allowing the gasket 5 to switch between the two states.

[0039] It should be noted that in the first state, the user can adjust the angle by freely swinging the male connector 2 by adjusting the contact position between the adjusting ring surface 24 and the mating surface 51. Because the contact pressure between the gasket 5 and the male connector 2 is small, the frictional resistance is low, making the angle adjustment operation very effortless and smooth. In the second state, after the angle adjustment is completed, the gasket 5 and the male connector 2 can be tightly fitted together. A large clamping force and frictional force are generated between the mating surface 51 of the gasket 5 and the adjusting ring surface 24 of the male connector 2, ensuring that the position and angle of the gasket 5 on the male connector 2 remain unchanged. At this time, the male connector 2 cannot rotate, and its angle is locked. The male connector 2 and the gasket 5 can achieve a very reliable and stable lock after angle adjustment, capable of withstanding huge external torques without loosening. The characteristics of the convex arc surface allow the male connector 2 to maintain uniform contact stress with the gasket 5 at any locking angle, improving the stability of the lock and the service life of the parts.

[0040] To ensure a tight fit between gasket 5 and male connector 2 while maintaining their relative positions, refer to... Figure 4 As shown, the liquid connector in this embodiment may further include a fastening assembly 6 detachably mounted on the male connector 2. A gasket 5 is disposed between the fastening assembly 6 and the adjusting ring surface 24. The fastening assembly 6 is configured to drive the gasket 5 to switch between two states when the fastening assembly 6 is moved. By changing the position of the fastening assembly 6 along the axial direction of the male connector 2, the fastening assembly 6 achieves a tight fit or separation between the gasket 5 and the male connector 2. When the gasket 5 is locked and fixed to the male connector 2 by the fastening assembly 6, the male connector 2 can be locked at a preset angle relative to the fastening assembly 6 by adjusting the engagement between the adjusting ring surface 24 and the mating surface 51.

[0041] Among them, reference Figure 4 , Figure 5 As shown, the fastening assembly 6 in this embodiment may include a fastener 61 and a flange 62. The fastener 61 is screwed onto the threaded section of the male connector 2. The flange 62 is an annular part that is detachably mounted between the fastener 61 and the gasket 5. Specifically, one end face of the flange 62 is in contact with the fastener 61, and the other end face is in contact with the gasket 5. When the fastener 61 is tightened, it moves axially along the male connector 2 and applies axial pressure to the flange 62. This pressure is uniformly transmitted to the gasket 5 through the flange 62, thereby driving the gasket 5 to switch between a first state and a second state. To further optimize the force transmission, the end face of the flange 62 that contacts the gasket 5 can be configured as a first transmission surface, which can be a plane, a conical surface, or a spherical surface. Correspondingly, the end face of the gasket 5 that contacts the flange 62 can be provided with a second transmission surface that matches the first transmission surface. This matching transmission surface design ensures that the force can drive the gasket 5 more effectively and uniformly. Because flange 62 is detachable, it can be removed individually, making maintenance or replacement of gasket 5 extremely convenient. As a pressure-bearing component, flange 62 disperses and buffers the concentrated pressure applied by fasteners 61 (such as nuts), then evenly transmits it to gasket 5. This effectively prevents fasteners 61 from directly squeezing, wearing, or even crushing gasket 5, thereby greatly improving the service life of gasket 5 and the reliability of the entire mechanism. By designing a matching transmission surface, flange 62 can more efficiently convert the axial movement of fasteners 61 into radial force that drives the state switching of gasket 5. This design ensures that the force is evenly distributed across all parts of gasket 5, resulting in a tighter and more reliable fit with the adjusting ring surface 24 of male connector 2, significantly improving the stability and strength of the locking.

[0042] To facilitate better transmission of axial pressure, refer to Figure 4 As shown, in this embodiment, the outer wall of the fastener 61 can be larger than the inner diameter of the flange 62. This design, where the outer diameter of the fastener 61 is larger than the inner diameter of the flange 62, ensures that the rotational thrust of the fastener 61 acts perpendicularly to the end face of the flange 62. This avoids problems such as excessive pressure, component damage (e.g., cracking of the flange 62 orifice) or low pressure transmission efficiency caused by an insufficient contact area.

[0043] Reference Figure 4 As shown, in this embodiment, the outer diameter of the flange 62 can be larger than the inner diameter of the gasket 5, ensuring that the first driving surface of the flange 62 can completely cover the second driving surface of the gasket 5. This allows the applied pressure to be evenly distributed across the entire surface of the gasket 5, thereby driving the gasket 5 to move evenly toward the male connector 2, thus facilitating a better and more secure fit between the gasket 5 and the male connector 2, and improving the rigidity and stability of the locking between the gasket 5 and the male connector 2.

[0044] To prevent axial displacement of fastener 61, which would reduce the stability between washer 5 and male connector 2, refer to... Figure 6 As shown, the liquid connector in this embodiment may further include a retaining ring 7 fixedly installed on the male connector 2, with the fastener 61 abutting against the retaining ring 7. Specifically, the adjusting part 23 of the male connector 2 is provided with a groove, and the retaining ring 7 is embedded in the groove, thereby being fixedly installed on the male connector 2.

[0045] Optional, refer to Figures 1-4 As shown, the liquid connector in this embodiment may also include a tail pipe 8 fixedly installed on the adjusting part 23. The tail pipe 8 is designed to extend the male connector 2, facilitating communication between the male connector 2 and other pipelines.

[0046] Furthermore, in order to improve the reliability of the connection between the adjustment part 23 and the tail tube 8, the tail tube 8 and the adjustment part 23 in this embodiment can be welded together.
