DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] Referring to Figure 1 , Figure 2 and Figure 3 , the utility model provides an embodiment: a kind of high pressure-resistant sealed quick connector, including plug valve 1 and socket valve 3, multiple mounting grooves 4 are equidistantly opened in the outside right side of socket valve 3, multiple mounting grooves 4 are all movably connected with locking ball 5 in the inside, baffle 6 is fixedly connected with the left side of the outside of socket valve 3, locking sleeve 7 is slidably connected with the outside of socket valve 3, tension spring 8 is fixedly connected with the right side of baffle 6, protrusion 9 is fixedly connected in the inside of locking sleeve 7, the right end of tension spring 8 is fixedly connected in the left side of protrusion 9, U-shaped groove 10 is opened in the outside of plug valve 1, multiple locking grooves 11 are equidistantly opened in the inner side of U-shaped groove 10, locking assembly is provided on the outside right side of locking sleeve 7, automatic blocking mechanism 2 is arranged in the inside of plug valve 1 and socket valve 3, and automatic blocking mechanism 2 is used to automatically seal when plug valve 1 and socket valve 3 are disconnected;

[0032] Specifically, when two components need to be connected, the plug valve 1 is inserted into the socket valve 3, the socket valve 3 is movably connected with the locking ball 5 in the multiple mounting grooves 4 equidistantly arranged on the right side of the outer part of the socket valve 3, and the U-shaped groove 10 arranged on the outer part of the plug valve 1 will be in contact with the locking ball 5 during the insertion process of the plug valve 1. The U-shaped groove 10 plays a guiding role, and when the plug valve 1 gradually penetrates, the inclined surface of the U-shaped groove 10 will press the locking ball 5 to move in the mounting groove 4 towards the center of the socket valve 3. Since the baffle 6 is fixedly connected to the left side of the outer part of the socket valve 3 and the locking sleeve 7 is slidably connected to the outer part of the baffle 6, the right end of the tension spring 8 on the right side of the baffle 6 is fixed to the left side of the protrusion 9 in the inner part of the locking sleeve 7. When the plug valve 1 is not completely inserted, the tension spring 8 is in an open state. When the plug valve 1 is inserted to the appropriate position, the locking groove 11 inside the U-shaped groove 10 is aligned with the locking ball 5. At this time, the elastic potential energy of the tension spring 8 is compressed, pushing the locking sleeve 7 to slide to the right along the outer part of the socket valve 3. The sliding of the locking sleeve 7 causes the locking ball 5 to be pressed into the locking groove 11, thereby locking the plug valve 1 and the socket valve 3 together, realizing the quick connection of the two. In order to further enhance the stability of the connection, the locking assembly is arranged on the right side of the outer part of the locking sleeve 7. Multiple threaded holes 12 equidistantly arranged on the right side of the outer part of the locking sleeve 7, and multiple fixed bolts 13 are respectively threadedly connected in the threaded holes 12. After the locking ball 5 preliminarily locks the plug valve 1 and the socket valve 3, the fixed bolts 13 can be tightened, so that the ends of the fixed bolts 13 are in close contact with the outer part of the plug valve 1, preventing the locking ball 5 from accidentally coming off the locking groove 11, and further improving the reliability of the connection. When the plug valve 1 and the socket valve 3 are connected, the annular groove 14 forms a sealed space with the inner wall of the socket valve 3. When high pressure is applied, this sealed space can effectively prevent the medium from leaking, ensuring the high pressure sealing performance of the connector. When the connector needs to be disassembled, first loosen the fixed bolts 13, then pull the locking sleeve 7 to the left, compress the tension spring 8, and make the locking ball 5 exit from the locking groove 11. At this time, the plug valve 1 can be easily pulled out of the socket valve 3, completing the disassembly operation, and realizing the functions of quick connection, reliable locking and high pressure sealing.

[0033] Referring to Figure 4 , the automatic blocking mechanism 2 comprises two fixed frames 201 fixedly connected to the inner parts of the plug valve 1 and the socket valve 3, respectively. The adjacent sides of the two fixed frames 201 are fixedly connected with stainless steel springs 202. The adjacent ends of the two stainless steel springs 202 are fixedly connected with limiting cylinders 203. The outer diameters of the two limiting cylinders 203 are matched with the inner diameters of the plug valve 1 and the socket valve 3, respectively. The adjacent sides of the two limiting cylinders 203 are fixedly connected with tapered flow guide blocks 204. The outer parts of the two tapered flow guide blocks 204 are fixedly connected with T-shaped rubber rings 205. The inner parts of the plug valve 1 and the socket valve 3 are designed in a tapered shape. The shapes of the two tapered flow guide blocks 204 are matched with the inner parts of the plug valve 1 and the socket valve 3, respectively.

[0034] Specifically, in the plug valve 1 and the socket valve 3, each has a fixed frame 201, which is fixed in the corresponding valve, when the plug valve 1 and the socket valve 3 are in the connected state, the two limiting barrels 203 are close to each other in the plug valve 1 and the socket valve 3 until they are connected, so that the stainless steel spring 202 is in a compressed state, the outer diameter of the limiting barrel 203 is accurately matched with the inner diameter of the plug valve 1 and the socket valve 3, which ensures that it will not swing during movement, the limiting barrel 203 is fixedly connected with the conical flow guide block 204 on the adjacent side, the plug valve 1 and the socket valve 3 are designed in a conical shape, and the conical flow guide block 204 is perfectly matched with the conical shape, so that in the connected state, the fluid can smoothly pass through the gap between the conical flow guide blocks 204, realizing normal transmission, because the conical flow guide block 204 is fixedly connected with the T-shaped rubber ring 205 outside, when connected, the T-shaped rubber ring 205 will completely block the fluid, playing a sealing role to prevent fluid leakage, when the plug valve 1 and the socket valve 3 need to be disconnected, the stainless steel spring 202 begins to release the elastic potential energy, and the spring force pushes the limiting barrel 203 to move towards the port direction of the plug valve 1 and the socket valve 3, the limiting barrel 203 drives the conical flow guide block 204 to move, because the conical flow guide block 204 is matched with the conical design inside the plug valve 1 and the socket valve 3, during movement, it gradually closely adheres to the inner wall of the plug valve 1 and the socket valve 3, at this time, the T-shaped rubber ring 205 also closely adheres to it, completely blocking the fluid passage inside the plug valve 1 and the socket valve 3, realizing automatic sealing and avoiding fluid leakage to the external environment, when reconnecting the plug valve 1 and the socket valve 3, the external force pushes the limiting barrel 203 to move in the opposite direction, compressing the stainless steel spring 202, so that the conical flow guide blocks 204 are separated from each other, the fluid passage is opened again, and the normal fluid transmission is restored, effectively guaranteeing the automatic sealing of the plug valve 1 and the socket valve 3 when disconnected, improving the safety and reliability of the connector in use.

[0035] Referring to Figure 2 , Figure 3 and Figure 5The locking assembly comprises a plurality of fixing bolts 13, a plurality of threaded holes 12 are equidistantly arranged on the outer right side of the locking sleeve 7, the plurality of fixing bolts 13 are respectively threadedly connected in the plurality of threaded holes 12, and an annular groove 14 is arranged on the outer right side of the plug valve 1; the right side of the protruding block 9 is fixedly connected with a buffer ring I 15, and the outer left side of the plug valve 1 is fixedly connected with a buffer ring II 16; the inner right end of the U-shaped groove 10 is fixedly connected with a sealing ring 17, and the size of the sealing ring 17 is matched with the inner size of the locking sleeve 7; the distal ends of the plurality of fixing bolts 13 are all provided with hexagonal guide grooves 18, and the outer sides of the plurality of hexagonal guide grooves 18 are all designed in a chamfered manner; the right end of the plug valve 1 and the left end of the socket valve 3 are both fixedly connected with hexagonal heads 19, and the shapes of the plurality of hexagonal heads 19 are all designed in a regular hexagonal shape; a threaded wall 20 is arranged in the plug valve 1, and the threaded wall 20 is designed in a standard interface;

[0036] Specifically, the locking assembly is composed of a plurality of fixing bolts 13 and a locking sleeve 7, a plurality of threaded holes 12 are equidistantly arranged on the outer right side of the locking sleeve 7, and the fixing bolts 13 are respectively threadedly connected in the threaded holes 12. After the plug valve 1 and the socket valve 3 are preliminarily locked by the locking ball 5, a tool can be inserted into the hexagonal guide groove 18 at the far end of the fixing bolt 13 to tighten the fixing bolt 13. The hexagonal guide groove 18 is designed with a chamfer on the outside, which facilitates the quick and accurate insertion of the tool, reduces the operation difficulty and time, and after the fixing bolt 13 is tightened, the end thereof abuts against the annular groove 14 on the outer right side of the plug valve 1, further preventing the locking sleeve 7 from sliding accidentally, enhancing the stability of the connection between the plug valve 1 and the socket valve 3, and ensuring that the connector will not loosen under such complex working conditions as high pressure vibration. During the connection process, the buffer ring one 15 fixedly connected to the right side of the protruding block 9 and the buffer ring two 16 fixedly connected to the left side of the plug valve 1 outside can be in contact and extruded with each other when the plug valve 1 is inserted into the socket valve 3. Due to the good elasticity, the buffer ring one 15 can buffer the impact force when the plug valve 1 is inserted, avoiding damage to the components caused by hard collision and prolonging the service life of the connector. At the same time, the close fit of the buffer ring one 15 and the buffer ring two 16 plays an auxiliary sealing role, reducing the possibility of fluid leakage from the connection between the plug valve 1 and the socket valve 3. The sealing ring 17 fixedly connected to the right end inside the U-shaped groove 10 has a size matching the inner size of the locking sleeve 7. When the locking sleeve 7 completes the locking action, the sealing ring 17 is in close contact with the inner wall of the locking sleeve 7, forming a sealed barrier and further improving the sealing performance of the connector connection part, preventing fluid leakage from the gap between the locking sleeve 7 and the plug valve 1. The right end of the plug valve 1 and the left end of the socket valve 3 are both fixedly connected with a hexagonal head 19, and the outer shape is designed as a regular hexagon, which can facilitate the operation of the corresponding tool during the installation or disassembly of the connector, increase the force point during the operation, and make it more labor-saving to plug in or pull out the plug valve 1 and the socket valve 3. The threaded wall 20 arranged inside the plug valve 1 is designed with a standard interface, which is convenient for connection with other components with standard threaded interfaces, enhances the universality and adaptability of the connector, and enables it to be better applied in different fluid transmission systems.

[0037] Working principle: the external right side of the socket valve 3 is equidistantly provided with a plurality of mounting grooves 4, and the locking balls 5 are movably connected in the mounting grooves 4. In the process of inserting the plug valve 1, the U-shaped groove 10 provided on the outer part of the plug valve 1 will be in contact with the locking balls 5, and the U-shaped groove 10 plays a guiding role. When the plug valve 1 gradually penetrates, the inclined surface of the U-shaped groove 10 will extrude the locking balls 5, so that the locking balls 5 move in the mounting groove 4 towards the center of the socket valve 3. Since the external left side of the socket valve 3 is fixedly connected with the baffle 6 and slidably connected with the locking sleeve 7, the right end of the tension spring 8 fixed on the left side of the protruding block 9 in the locking sleeve 7 is on the right side of the baffle 6. When the plug valve 1 is not completely inserted, the tension spring 8 is in an open state. When the plug valve 1 is inserted to the appropriate position, the locking groove 11 inside the U-shaped groove 10 is aligned with the locking ball 5. At this time, the elastic potential energy of the tension spring 8 is compressed, which pushes the locking sleeve 7 to slide to the right along the outer part of the socket valve 3. The sliding of the locking sleeve 7 causes the locking balls 5 to be extruded into the locking groove 11, thereby locking the plug valve 1 and the socket valve 3 together, realizing the quick connection of the two. In order to further enhance the stability of the connection, the external right side of the locking sleeve 7 is equidistantly provided with a plurality of threaded holes 12, and a plurality of fixed bolts 13 are respectively threadedly connected in the threaded holes 12. After the locking balls 5 preliminarily lock the plug valve 1 and the socket valve 3, the fixed bolts 13 can be tightened, so that the ends of the fixed bolts 13 are in close contact with the outer part of the plug valve 1, preventing the locking balls 5 from accidentally coming off the locking groove 11, and further improving the reliability of the connection. When the plug valve 1 and the socket valve 3 are connected, the annular groove 14 forms a sealed space with the inner wall of the socket valve 3. When high pressure is borne, this sealed space can effectively prevent medium leakage, ensuring the high pressure sealing performance of the connector. When the connector needs to be disassembled, the fixed bolts 13 are first loosened, and then the locking sleeve 7 is pulled to the left, compressing the tension spring 8 and making the locking balls 5 exit from the locking groove 11. At this time, the plug valve 1 can be easily pulled out of the socket valve 3, completing the disassembly operation.

[0038] And, the fixed frame 201 is fixed in the plug valve 1 and the socket valve 3 respectively, when the plug valve 1 and the socket valve 3 are in the connected state, the two limiting barrels 203 are close to each other in the plug valve 1 and the socket valve 3 until the joint, the stainless steel spring 202 is in the compressed state, the limiting barrel 203 outer diameter and the plug valve 1 and the socket valve 3 inner diameter size precision match, ensure that it does not swing in the moving process, the limiting barrel 203 adjacent side fixedly connected with the conical flow guide block 204, the plug valve 1 and the socket valve 3 inside adopt conical design, and the conical flow guide block 204 shape and it perfectly adapt, make it in the connected state, fluid can smoothly pass through the gap between the conical flow guide block 204, realize normal transmission, because the conical flow guide block 204 outside fixedly connected with the T-shaped rubber ring 205, when connecting, the T-shaped rubber ring 205 will completely block the fluid, play a sealing role, prevent fluid leakage, when the plug valve 1 and the socket valve 3 need to be disconnected, the stainless steel spring 202 begins to release elastic potential energy, the spring force pushes the limiting barrel 203 to move towards the port direction of the plug valve 1 and the socket valve 3, the limiting barrel 203 drives the conical flow guide block 204 to move, because the conical flow guide block 204 and the conical design inside the plug valve 1 and the socket valve 3 match, in the moving process, gradually close to the inner wall of the plug valve 1 and the socket valve 3, at this time, the T-shaped rubber ring 205 also closely adheres, completely block the fluid passage inside the plug valve 1 and the socket valve 3, realize automatic sealing, avoid fluid leakage to the external environment, when reconnecting the plug valve 1 and the socket valve 3, the external force pushes the limiting barrel 203 to move reversely, compresses the stainless steel spring 202, makes the conical flow guide block 204 separate from each other, the fluid passage is opened again, restores normal fluid transmission.

[0039] Finally, it should be noted that: the above only for preferred embodiments of the utility model have described, and not for limiting the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or make equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be contained in the protection scope of the utility model.
