Description

Technical Field

[0001] This application belongs to the field of hydraulic coupling technology, specifically a hydraulic coupling that facilitates quick connection. Background Technology

[0002] Hydraulic quick couplings are essential components in hydraulic systems, enabling rapid and safe connection and disconnection. They are widely used in agriculture, construction, and forestry. Through a rotary joint, they allow operators to quickly connect or disconnect pipelines while providing excellent sealing performance to prevent leaks. Depending on the application requirements, hydraulic quick couplings are available in various types, such as open / closed, flat-head, and ball-type, suitable for different working environments. Choosing the appropriate hydraulic quick coupling can improve work efficiency and ensure system safety and reliability.

[0003] For example, application CN210770904U discloses a hydraulic quick coupling for hydraulic applications, including a male connector and a female connector. The female connector has a dustproof device on its top, and the dustproof device has a locking part on its top. The male connector has a connecting part at its bottom. The dustproof device includes a dustproof device housing, and the top and bottom of the dustproof device housing are respectively provided with two dustproof lower support arms. This utility model relates to the field of quick coupling technology. This hydraulic quick coupling for hydraulic applications, through the docking of the male connector and the female connector, compresses the elastic part, and the dustproof upper support arm is squeezed out of its original position into a pre-reserved groove due to the impact force from the male connector. After docking, the dustproof upper support arm returns to its original position from the pre-reserved groove. This utility model has a simple structure, is easy to operate, has a fast connection speed, and a good sealing effect, effectively isolating dust and other impurities at the connection point, providing convenience for users.

[0004] However, during the implementation of this application, it was discovered that in scenarios requiring interlocking, there was no reference mechanism for interlocking. Utility Model Content

[0005] The purpose of this application is to provide a hydraulic connector that facilitates quick and easy connection, in order to solve the problem mentioned above where there is no reference mechanism for insertion in scenarios requiring insertion.

[0006] The technical solution adopted in this application is as follows: a hydraulic connector that facilitates quick docking includes an insertion tube and a connecting tube. A force-bearing plate is welded to the outer surface of the insertion tube. A reference side plate is welded to the outer surface of the connecting tube on one side corresponding to the insertion tube. A limit strip is rotatably connected to the inner surface of the reference side plate. A limit pin is welded to the outer surface of the connecting tube. A groove is welded to the outer surface of the connecting tube below the limit pin.

[0007] By adopting the above technical solution, when the insertion tube is inserted into the connecting tube, the force plate facilitates the force application by the user, the reference side plate completes the positioning on both sides, the lower part of the limiting strip is supported by the sliding groove, and the upper part is limited by the limiting pin. The whole is easy to adjust when entering the limiting pin. After the limiting strip is inserted into the limiting hole, it is fixed. During the disassembly process, the limiting strip deforms due to the limiting pin corresponding to the limiting strip, which facilitates the release of the limiting hole and completes the disassembly. The overall disassembly is simple and quick.

[0008] As a further description of the above technical solution, a sealing ring is fixedly connected to the outer surface of the insertion tube, and a spring is provided on the outer surface of the reference side plate away from the rotation axis.

[0009] By adopting the above technical solution, after the insertion tube is inserted into the connecting tube, the sealing ring facilitates the sealing of the corresponding contact surface. The spring ensures that the outer hook always faces outward when the limit strip is not under force. When the connecting tube is inserted, the corresponding outer surface squeezes the limit strip and the corresponding spring engages with the limit hole.

[0010] As a further description of the above technical solution, a rotating shaft is provided on the outer surface of the connecting pipe, and a half-bent pipe is welded to the outer surface of the rotating shaft.

[0011] By adopting the above technical solution, the connecting pipe and the half-bend pipe can be rotated by the rotating shaft to facilitate the upward tilting of the outer end of the connecting pipe. Thus, when disassembling and disconnecting, the oil circuit is separated by gravity, avoiding the risk of oil accumulating at the connection and causing spraying.

[0012] As a further description of the above technical solution, a pin is welded to the outer surface of the reference side plate, and a protective frame is welded to the upper surface of the half-side bend.

[0013] By adopting the above technical solution, the outer frame is protected to ensure the stability of the connecting pipe tilt, avoiding the impact of external pressure on the pipe connection, while the slot is set to ensure the insertion and fixation of the pin rod.

[0014] As a further description of the above technical solution, the outer surface of the half-bent tube is provided with a limiting hole corresponding to the limiting strip, and the outer surface of the protective frame is provided with a slot corresponding to the outer surface of the pin rod.

[0015] By adopting the above technical solution, the limiting hole facilitates the insertion of the limiting strip after deformation, ensuring the stability of the connection between the insertion tube and the connecting tube, and the pin rod ensures the fixation of the connection between the insertion tube and the connecting tube after being inserted into the slot.

[0016] As a further description of the above technical solution, a support plate is welded to the outer surface of the protective frame, and an outlet pipe is welded to the outer surface of the support plate.

[0017] By adopting the above technical solution, the support plate and the outlet pipe provide space at the output end of the connecting pipe, ensuring the stability of the pipeline.

[0018] As a further description of the above technical solution, a tapered tube is welded to the outer surface of the connecting pipe, and a deformable sealing sheet is fixedly connected to the outer surface of the tapered tube.

[0019] By adopting the above technical solution, the oil output from the connecting pipe is introduced into the outlet pipe through the tapered pipe. The tapered pipe and the support plate are movably connected to ensure that the connecting pipe is tilted relative to the outer frame. The deformable sealing sheet always seals the oil output from the tapered pipe inside the outlet pipe through deformation.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] 1. In this application, when the insertion tube is inserted into the connecting tube, the force plate facilitates the force application by the user, the reference side plate completes the positioning on both sides, the lower part of the limiting strip is supported by the sliding groove, and the upper part is limited by the limiting pin. The whole is easy to adjust when entering the limiting pin. After the limiting strip is inserted into the limiting hole, it is fixed. During the disassembly process, the limiting strip deforms due to the limiting pin corresponding to the limiting strip, which facilitates the release of the limiting hole and completes the disassembly. The overall disassembly is simple and quick.

[0022] 2. In this application, during the disassembly process, by pulling out a small part, after the pin rod and slot contact the limit, the insertion tube is lifted, and the limit strip deforms outward downward under the limit pin, releasing the limit at the limit hole. Then the insertion tube and connecting tube are lifted. After standing for a period of time, the oil is separated by gravity during the standing process. After the insertion tube and connecting tube are pulled out, oil will not spray out and cause external environmental pollution. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0031] Example:

[0032] Reference Figure 1-5 A hydraulic connector for easy and quick connection includes an insertion tube 1, a force-bearing plate 3 welded to the outer surface of the insertion tube 1, a reference side plate 4 welded to the outer surface of the connecting tube 2 on one side corresponding to the insertion tube 1, a limit strip 5 rotatably connected to the inner surface of the reference side plate 4, a limit pin 7 welded to the outer surface of the connecting tube 2, and a groove 8 welded to the outer surface of the connecting tube 2 below the limit pin 7.

[0033] When the insertion tube 1 is inserted into the connecting tube 2, the force plate 3 facilitates the force application by the user, the reference side plate 4 completes the positioning on both sides, the lower part of the limiting strip 5 is supported by the sliding groove 8, and the upper part is limited by the limiting pin 7. The whole is easy to adjust when entering the limiting pin 7. After the limiting strip 5 is inserted into the limiting hole 14, it is fixed. During the disassembly process, the limiting strip 5 deforms due to the limiting pin 7 corresponding to the limiting of the limiting strip 5, which makes it easy to release the limiting of the limiting hole 14 and complete the disassembly. The overall disassembly is simple and quick.

[0034] Reference Figure 1-3 A sealing ring 9 is fixedly connected to the outer surface of the insertion tube 1, and a spring 10 is provided on the outer surface of the reference side plate 4 away from the rotation axis 6.

[0035] After the insertion tube 1 is inserted into the connecting tube 2, the sealing ring 9 facilitates the sealing of the corresponding contact surface. The spring 10 ensures that the outer hook of the limiting strip 5 is always outward when it is not under force. When the connecting tube 2 is inserted, the corresponding outer surface of the limiting strip 5 is pressed and the corresponding spring 10 is engaged in the limiting hole 14.

[0036] Reference Figure 1-5 A rotating shaft 6 is provided on the outer surface of the connecting pipe 2, and a half-bent pipe 11 is welded to the outer surface of the rotating shaft 6.

[0037] The connecting pipe 2 and the half-bend pipe 11 are rotated by the rotating shaft 6 to make the outer end of the connecting pipe 2 tilt upward. Thus, when disassembling and disconnecting, the oil circuit is separated by gravity, avoiding the risk of oil accumulating at the connection and causing spraying.

[0038] Reference Figure 1-3 A pin rod 15 is welded to the outer surface of the reference side plate 4, and a protective frame 12 is welded to the upper surface of the half-side bend 11.

[0039] The outer frame 12 ensures the stability of the inclined connecting pipe 2 and avoids the influence of external pressure on the pipe connection. At the same time, the slot 17 is provided to ensure the insertion and fixation of the pin 15.

[0040] Reference Figure 1-4 The half-bend tube 11 has a limit hole 14 on the outer surface of the limit strip 5, and the protective frame 12 has a slot 17 on the outer surface of the pin rod 15.

[0041] The limiting hole 14 facilitates the insertion of the limiting strip 5 after deformation, ensuring the stability of the connection between the insertion tube 1 and the connecting tube 2. The pin rod 15 is inserted into the slot 17 to ensure the fixation of the connection between the insertion tube 1 and the connecting tube 2.

[0042] Reference Figure 1-5 A support plate 13 is welded to the outer surface of the protective frame 12, and an outlet pipe 16 is welded to the outer surface of the support plate 13.

[0043] The support plate 13 and the outlet pipe 16 provide space for the output end of the connecting pipe 2 to ensure the stability of the pipeline.

[0044] Reference Figure 1-5 A tapered tube 18 is welded to the outer surface of the connecting pipe 2, and a deformable sealing sheet 19 is fixedly connected to the outer surface of the tapered tube 18.

[0045] The oil output from the connecting pipe 2 is introduced into the outlet pipe 16 through the tapered pipe 18. The tapered pipe 18 and the support plate 13 are movably connected to ensure that the connecting pipe 2 is tilted relative to the protective outer frame 12. The deformable sealing sheet 19 always seals the oil output from the tapered pipe 18 inside the outlet pipe 16 through deformation.

[0046] The implementation principle of the hydraulic connector embodiment of this application that facilitates quick connection is as follows:

[0047] In use, the connector is fixedly connected to the pipeline via the outlet pipe 16 or the outer surface of the support plate 13. The half-bend pipe 11, the protective frame 12, and the support plate 13 form an integral unit. The connecting pipe 2 and the half-bend pipe 11 are rotated by the rotating shaft 6 to facilitate the upward tilting of the outer end of the connecting pipe 2. Thus, when disassembling, the oil circuit is separated by gravity, avoiding the risk of oil accumulation at the connection point and spraying. The other end is fixed to the pipeline by the force plate 3. After the insertion pipe 1 is inserted into the connecting pipe 2, the sealing ring 9 facilitates the sealing of the corresponding contact surface. The reference side plate 4 is on both sides. The lower part of the limit strip 5 is supported by the sliding groove 8, and the upper part is supported by the sliding groove 8. The limiting pin 7 is fixed by inserting the pin 15 into the slot 17 and the limiting strip 5 being locked in the groove of the limiting hole 14. During disassembly, by pulling it out slightly, the pin 15 and slot 17 contact the limiting point, and the insertion tube 1 is lifted. The limiting strip 5 deforms downward under the limitation of the limiting pin 7, releasing the limiting point at the limiting hole 14. Then the insertion tube 1 and the connecting tube 2 are lifted. After standing for a period of time, they are pulled out at an angle to ensure that the oil on the side of the connecting tube 2 is sprayed out during disassembly. At one end of the insertion tube 1, a right-angle bend is connected to solve the problem of spraying at the joint connection when disassembling and lifting.

[0048] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
