As shown in fig. 1 and 2, the male connector 1 and the female connector 2 each include a connecting cylinder 3, and the opposite ends of the connecting cylinders 3 of the male connector 1 and the female connector 2 are tapered sections 4, and the other ends are threaded sections 5 for connection with a hydraulic oil pipe. The cone top of the cone-shaped section 4 is provided with an oil passing hole 6, and the oil passing hole 6 is used as one component part of an oil way after the male connector 1 and the female connector 2 are combined. The inside conical section 4 of the oil passing hole 6 is internally provided with a sealing tip cone 7 matched with the oil passing hole 6, the taper of the sealing tip cone 7 is matched with that of the conical section 4, and the sealing tip cone 7 is tightly pressed at the oil passing hole 6 through an elastic sealing assembly and seals the oil passing hole 6.
That is, in the non-coupled state as shown in fig. 2, the sealing tip cone 7 always abuts against the inner wall of the tapered section 4 under the elastic action of the elastic sealing assembly, so that the oil passing hole 6 is closed by the sealing tip cone 7, and when the male connector 1 and the female connector 2 are coupled, the sealing tip cone 7 can be retracted into the tapered section 4 again, so that the oil passing hole 6 is not blocked any more.
The specific form of the elastomeric seal assembly of the present invention is more numerous, but one of the more common is spring-supported, as shown in fig. 2: the elastic sealing assembly comprises a supporting disc 10 fixedly arranged in the middle section of the connecting cylinder 3, the supporting disc 10 and the connecting cylinder 3 are generally of an integrated structure, and the elastic sealing assembly can also be arranged in the connecting cylinder 3 in an internally-installed mode under partial conditions. An oil through hole 11 is formed in the support disc 10 to form a complete oil path, and a support spring 12 is arranged between the support disc 10 and the sealing tip cone 7. When the male connector 1 and the female connector 2 are in a separated state, the sealing tip cone 7 is pressed at the oil passing hole 6 through the supporting spring 12, and of course, in order to further ensure tightness, the outer surface of the sealing tip cone 7 may be provided with a sealing rubber coating, and correspondingly, the sealing rubber coating may also be provided on the inner wall of the conical section 4.
On this basis, in order to further improve the stability of the installation of the supporting spring 12, as shown in fig. 2 and 5, the disc surface of the supporting disc 10 and the inner surface of the sealing tip cone 7 are both provided with an adaptive positioning boss 13, and two ends of the supporting spring 12 are located at the positioning boss 13. The shape and specific dimensions of the positioning boss 13 are adaptively designed according to the supporting spring 12, and the structure is simple and will not be described in detail in the present invention.
In addition, as shown in fig. 2, the middle section of the connecting cylinder 3 of the female connector 2 extends towards one end where the conical section 4 is located to form a sleeve joint cylinder 8, and the inner diameter of the sleeve joint cylinder 8 is matched with the outer diameter of the connecting cylinder 3 of the male connector 1. That is, the socket 8 on the female connector 2 is matched with the connecting cylinder 3 of the male connector 1, and the connecting cylinder 3 of the male connector 1 can be stably inserted into the socket 8 of the female connector to form stable and reliable plug-in connection. The socket barrel 8 of the female connector 2 and the middle section of the connecting barrel 3 of the male connector 1 are locked by a quick locking mechanism. And after the male connector 1 is inserted into the female connector 2 to form butt joint and locking, as shown in fig. 3, the sealing tip cone 7 of the male connector 1 and the female connector 2 can be retracted into the tapered section 4, so that an oil passing channel 9 is formed between the outer surface of the sealing tip cone 7 and the inner surface of the tapered section 4.
In the use process, when the butt joint is formed, the connecting cylinder 3 of the male connector 1 can be directly inserted into the sleeve joint cylinder 8 of the female connector 2, the sleeve joint cylinder 8 and the connecting cylinder 3 can enable the combination positioning property of the male connector 1 and the female connector 2 to be better, and meanwhile, the quick locking of the male connector and the female connector can be realized by utilizing the quick locking mechanism; in addition, when the male connector 1 and the female connector 2 are not combined, the sealing tip cone 7 in the conical section 4 of the connecting cylinder 3 can tightly press the inner surface of the conical section 4 under the support of the elastic sealing assembly, so that the oil passing hole 6 is effectively sealed by the sealing tip cone 7, the hydraulic oil in the male connector and the female connector is prevented from leaking, and good sealing performance is achieved.
The quick locking mechanism has more specific structures, such as screw thread screwing locking, clamping locking and the like, wherein the quick locking mechanism is most convenient and quick in a clamping locking mode, and comprises two groups of quick locking structures which are symmetrically distributed as shown in fig. 2 and 3. The quick locking mechanism comprises a locking groove 14 arranged on the inner surface of the overhanging end of the sleeve 8 of the female connector 2, wherein the locking groove 14 extends along the length direction of the sleeve 8 and is formed by outwards sinking the side wall of the sleeve 8. As shown in fig. 6, the inner end of the locking groove 14 is provided with a clamping groove 15, the groove wall of the clamping groove 15 is provided with a mounting hole, and an unlocking button 16 is arranged in the mounting hole, and the unlocking button 16 and the mounting hole form a sliding fit.
The quick locking mechanism further comprises an annular first check ring 17 arranged on the outer surface of the middle section of the connecting barrel 3 of the male connector 1, an elastic clamping strip 18 is arranged on one surface of the first check ring 17, which faces the sleeve joint barrel 8, the position of the elastic clamping strip 18 is opposite to the locking groove 14, and a clamping hook 19 is arranged at the end part of the elastic clamping strip 18. When the male connector 1 is combined with the female connector 2, the elastic clamping strip 18 stretches into the locking groove 14, and the clamping hook 19 is clamped at the step of the clamping groove 15. And the catch 19 is positioned opposite the unlocking button 16.
When the quick locking mechanism is adopted, the male connector 1 is inserted into the female connector 2, the elastic clamping strip 18 on the male connector 1 stretches into the locking groove 14, and when the right end of the sleeve joint cylinder 8 moves to be in contact with the first check ring 17 as shown in fig. 2, the clamping hook 19 on the elastic clamping strip 18 just moves into the clamping groove 15, and under the elastic action of the elastic clamping strip 18, the clamping hook 19 just clamps on the step of the joint part of the right end of the clamping groove 15 and the locking groove 14, so that the male connector 1 is prevented from withdrawing, and locking is realized. When the male connector 1 is required to be withdrawn, the unlocking buttons 16 of the two groups of quick locking mechanisms are pressed simultaneously, the unlocking buttons 16 can drive the hooks 19 to separate from the steps, and the male connector 1 is withdrawn outwards.
Of course, on the basis of this, in order to prevent the unlocking button 16 from being touched by mistake, the present invention may also be provided with a protective sleeve 20 on the outside. As shown in fig. 3, the male connector further comprises a protection sleeve 20, wherein the protection sleeve 20 is arranged outside the connecting cylinder 3 of the male connector 1, and the inner side wall of the protection sleeve 20 is provided with a guiding edge 21 extending along the length direction of the protection sleeve 20. The edge of the first retainer ring 17 is provided with a bayonet matched with the guide edge 21, and the guide edge 21 of the protection sleeve 20 is clamped in the bayonet of the first retainer ring 17 and forms sliding fit with the connecting cylinder 3 of the male connector 1. An annular second check ring 22 is arranged outside the middle section of the connecting barrel 3 of the female connector 2, and a magnetic adsorption connection is formed between the end part of the protection sleeve 20 and the second check ring 22. That is, the present invention can cover the position of the quick locking mechanism by sliding the protection sleeve 20, thereby realizing the protection of misoperation, and greatly reducing the risks caused by misoperation and environmental interference.
Regarding how the retraction driving of the sealing tip cone 7 is achieved when the male connector 1 and the female connector 2 are combined, one of the simplest ways of the invention is that, as shown in fig. 3, the outer surface of the tip of the sealing tip cone 7 is correspondingly provided with a push rod 23, and when the male connector 1 and the female connector 2 are combined, the sealing tip cone 7 on the male connector 1 and the female connector 2 is retracted into the conical section 4 by the mutual pushing of the push rod 23.
However, in the use process of the invention, when the male connector 1 and the female connector 2 are combined, the opening of the oil way is realized through the backspacing of the sealing tip cone 7, so the backspacing stability of the sealing tip cone 7 has great influence on the invention, and the invention relates to whether the oil way can be stably opened in the combination process. While the supporting spring 12 acts as an elastic supporting member of the sealing tip cone 7, which always applies a supporting elastic force to the sealing tip cone 7.
As shown in fig. 3, in the case that hydraulic oil passes through the inside of the system, assuming that the direction of the oil path in fig. 3 is from left to right, the sealing tip cone 7 in the female joint 2 is subjected to hydraulic oil thrust toward the right in addition to the elastic force of the supporting spring 12, and when the pressure in the system is high, it may happen that the hydraulic oil thrust directly pushes the sealing tip cone 7 to a position where it is combined with the tapered section 4, and at this time, the oil passage 9 of the female joint 2 is actually closed; this is shown to be unsuitable for use in high pressure systems or requires a great adjustment of the parameters of the support spring 12 to be achieved with a large support spring force, which in turn affects the ease of incorporation.
Therefore, the invention can realize effective driving of the sealing tip cone 7 inside the male and female connectors when the male and female connectors are combined through the following design: as shown in fig. 4 and 5, when the male connector 1 and the female connector 2 are combined, two annular sealing support rings 24 are arranged between the sealing tip cones 7 of the male connector 1 and the female connector 2, the cross section of each sealing support ring 24 is triangular, and the included angle between each sealing support ring 24 and the sleeve 8 and the conical section 4 is matched. A compression spring 25 is arranged between the opposite surfaces of the two sealing support rings 24, and two ends of the compression spring 25 are connected with the sealing support rings 24. In order to ensure the support stability of the compression spring 25 on the surface of the seal support ring 24, positioning grooves 28 are formed in the opposite surfaces of the two seal support rings 24, and two ends of the compression spring 25 are located in the positioning grooves 28.
As shown in fig. 5 and 8, the side wall of the conical section 4 of the connecting cylinder 3 is uniformly provided with a plurality of supporting holes 26 in a ring shape, and as shown in fig. 5 and 7, the surface of the sealing supporting ring 24 opposite to the conical section 4 is provided with a plurality of supporting blocks 27 matched with the supporting holes 26. When the male connector 1 and the female connector 2 are combined, the supporting block 27 on the sealing supporting ring 24 passes through the supporting hole 26 and abuts against the sealing tip cone 7. The sealing tip cone 7 on the male connector 1 and the female connector 2 is retracted into the conical section 4 by the abutment of the support blocks 27.
That is, when the above design is adopted, the supporting block 27 on the sealing supporting ring 24 can extend into the tapered section 4 through the supporting hole 26 when the butt joint of the male connector 1 and the female connector 2 is completed, so that the opening of the oil passing channel 9 is always kept between the sealing tip cone 7 and the tapered section 4 by the supporting of the supporting block 27, and the condition that the oil passing channel 9 is closed is not caused even in a larger system pressure. Meanwhile, through the design, the sealing performance between the sleeve section 8 of the female connector 2 and the connecting cylinder 3 of the male connector 1 is further effectively improved, so that the overall performance and the universality of the invention are greatly improved.
