An easy-to-connect ultra-high voltage quick connector

Abstract

This utility model relates to the field of high-voltage connector technology and discloses an ultra-high-voltage quick connector that facilitates connection. It includes a female connector with a male connector inserted into it. Both the female and male connectors are equipped with a fixing mechanism. The fixing mechanism includes a locking ring, a mounting plate, and a turntable. The locking ring is fixedly sleeved on the outer wall of the male connector, and the mounting plate is fixedly sleeved on the outer wall of the female connector. After the male connector is inserted into the female connector, rotating the turntable causes an arc-shaped sliding hole to move a sliding rod. This causes the sliding rod to move a locking block along a rectangular sliding hole on the mounting plate and lock it onto the locking ring, achieving quick fixing of the female and male connectors. For disassembly, rotating the turntable in the opposite direction disengages the locking block from the locking ring, allowing the male connector to be pulled out. This quick fixing and separation can be achieved without screw tightening, solving the problem of inconvenient disassembly of traditional connectors and improving operational efficiency.

Description

Technical Field

[0001] This utility model relates to the field of high-voltage connector technology, specifically to an ultra-high-voltage quick connector that is easy to connect. Background Technology

[0002] Hydraulic hoses are generally divided into steel wire braided hydraulic hoses and steel wire spiral hydraulic hoses. Hydraulic hoses are mainly composed of a liquid-resistant inner rubber layer, a middle rubber layer, multiple layers of steel wire spiral reinforcement, and an outer rubber layer, and are mainly responsible for the directional transmission of hydraulic oil.

[0003] For example, the ultra-high pressure hydraulic hose quick connector disclosed in CN218294845U can be connected and fixed between the hose body and the connector body by inserting the hose body into the installation groove and using the sliding connection between the limiting post and the limiting groove. Compared with the threaded connection, it is more convenient to operate and reduces the time and effort spent on connecting the connector body and the hose body. The rolling of the balls inside the connector body on the inner wall of the annular groove ensures that the hose body will not rotate synchronously and become loose when the connector body is connected to the equipment, thus making the connection between the hose body and the connector body more secure and improving the performance of the hose body.

[0004] However, the existing technology is inconvenient for quick disassembly of the connector during use, which affects the actual use effect. Therefore, an ultra-high pressure quick connector that is easy to connect is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an ultra-high voltage quick connector that is easy to connect, addressing the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an ultra-high voltage quick connector that is easy to connect, including a female connector, a male connector inserted into the female connector, and a fixing mechanism provided on the female connector and the male connector;

[0007] The fixing mechanism includes a locking ring, a mounting plate, and a turntable. The locking ring is fixedly sleeved on the outer wall of the male connector, and the mounting plate is fixedly sleeved on the outer wall of the female connector. A locking block is slidably connected to the right side of the mounting plate, and the locking block engages with the locking ring. A sliding rod is connected to the left side of the locking block. The turntable is rotatably connected to the outer wall of the female connector via a bearing. An arc-shaped sliding hole is provided on the right side of the turntable, and the outer wall of the sliding rod is slidably connected to the arc-shaped sliding hole. After the male connector is inserted into the female connector, rotating the turntable causes the arc-shaped sliding hole to move the sliding rod, which in turn causes the locking block to slide along the rectangular sliding hole on the mounting plate and engage with the locking ring, thus achieving rapid fixing of the female and male connectors. During disassembly, rotating the turntable in the opposite direction causes the locking block to disengage from the locking ring, allowing the male connector to be pulled out. Rapid fixing and separation can be achieved without tightening the threads, solving the problem of inconvenient disassembly of traditional connectors and improving operational efficiency.

[0008] Preferably, a rectangular sliding hole is provided on the right side of the mounting plate, and the locking block is slidably connected in the rectangular sliding hole. The rectangular sliding hole restricts the movement trajectory of the locking block, so that it slides only in the radial direction, ensuring that the locking block accurately engages or disengages from the locking protrusion ring, and avoiding engagement failure caused by misalignment.

[0009] Preferably, the back of the locking block is provided with a slot, and the outer wall of the locking protrusion is engaged in the slot. The mechanical engagement restricts the axial separation of the male and female connectors, ensuring that the connection does not loosen under ultra-high pressure conditions, adapting to ultra-high pressure fluid impact, and preventing accidental disconnection.

[0010] Preferably, there are two locking blocks, two sliding rods, and two arc-shaped sliding holes, which are arranged in an equally spaced circle. When the turntable is rotated, the locking blocks on both sides are simultaneously engaged with the locking protrusions, applying a fixing force from a symmetrical direction, so that the male connector is subjected to balanced force and the overall connection stability is improved.

[0011] Preferably, the female connector is provided with a limiting mechanism, which includes: a fixed plate connected to the outer wall of the female connector; a spring connected to the left side of the fixed plate; a pull block connected to the left end of the spring; and a plug rod connected to the right side of the pull block. The plug rod is slidably connected to the fixed plate. A slot is provided on the left side of the turntable, and the right end of the plug rod is inserted into the slot. The spring force pushes the right end of the plug rod into the slot on the left side of the turntable, limiting the rotation of the turntable and ensuring that the locking block and the locking protrusion are stably engaged. When the turntable needs to be rotated, the pull block is pulled to stretch the spring and drive the plug rod out of the slot to unlock it, avoiding loosening of the locking block due to vibration or accidental contact and enhancing connection safety.

[0012] Preferably, the female connector and the male connector are provided with a sealing mechanism, the sealing mechanism including: an annular sealing plate, the annular sealing plate is connected to the left end of the male connector, the right end of the female connector has a sealing groove, the annular sealing plate is inserted into the sealing groove, and an annular sealing gasket is connected to the left side of the annular sealing plate. The outer wall of the annular sealing gasket abuts against the inner wall of the sealing groove. When the male connector is inserted into the female connector, the annular sealing plate is inserted into the sealing groove, and at the same time, the annular sealing gasket undergoes elastic deformation due to compression, filling the gap of the sealing groove, preventing fluid leakage, and improving the safety performance of the connector.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. This type of easy-to-connect ultra-high voltage quick connector allows the male connector to be inserted into the female connector. By rotating the turntable, the arc-shaped sliding hole on it drives the sliding rod to move, causing the sliding rod to move the locking block along the rectangular sliding hole on the mounting plate and lock it onto the locking protrusion ring, thus achieving quick fixation of the female connector and the male connector. When disassembling, rotating the turntable in the opposite direction causes the locking block to disengage from the locking protrusion ring, allowing the male connector to be pulled out. Quick fixation and separation can be achieved without tightening the threads, solving the problem of inconvenient disassembly of traditional connectors and improving operational efficiency.

[0015] 2. This easy-to-connect ultra-high pressure quick connector uses spring force to push the right end of the plug rod into the slot on the left side of the turntable, restricting the rotation of the turntable and ensuring a stable engagement between the locking block and the locking protrusion ring. When the turntable needs to be rotated, pulling the pull block stretches the spring and causes the plug rod to disengage from the slot to unlock it, preventing the locking block from loosening due to vibration or accidental contact, thus enhancing connection safety. When the male connector is inserted into the female connector, the annular sealing plate is inserted into the sealing groove, and at the same time, the annular sealing gasket undergoes elastic deformation due to compression, filling the gap in the sealing groove, preventing fluid leakage, and improving the safety performance of the connector.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0026] Please see Figure 1-5One embodiment of this utility model is: an ultra-high voltage quick connector for easy connection, including a female connector 1, a male connector 2 inserted into the female connector 1, and a fixing mechanism 3 provided on the female connector 1 and the male connector 2; the fixing mechanism 3 includes: a locking protrusion ring 31, a mounting plate 32, and a turntable 35. The locking protrusion ring 31 is fixedly sleeved on the outer wall of the male connector 2, and the mounting plate 32 is fixedly sleeved on the outer wall of the female connector 1. A locking block 33 is slidably connected to the right side of the mounting plate 32, and the locking block 33 is engaged with the locking protrusion ring 31. The back of the mounting plate 32 has a slot, and the outer wall of the locking ring 31 is engaged in the slot. This mechanical engagement restricts the axial separation of the male connector 2 and the female connector 1, ensuring a secure connection under ultra-high pressure conditions, adapting to ultra-high pressure fluid impact, and preventing accidental disconnection. The right side of the mounting plate 32 has a rectangular sliding hole, and the locking block 33 is slidably connected within this hole. The rectangular sliding hole restricts the movement trajectory of the locking block 33, ensuring it slides only radially. This guarantees that the locking block 33 accurately engages or disengages from the locking ring 31, preventing misalignment. In case of connection failure, a sliding rod 34 is connected to the left side of the locking block 33. The turntable 35 is rotatably connected to the outer wall of the female connector 1 via a bearing. An arc-shaped sliding hole 36 is provided on the right side of the turntable 35. The outer wall of the sliding rod 34 is slidably connected to the arc-shaped sliding hole 36. There are two locking blocks 33, two sliding rods 34, and two arc-shaped sliding holes 36, which are arranged in an equally spaced circle. When the turntable 35 is rotated, the locking blocks 33 on both sides simultaneously engage with the locking protrusions 31, applying a fixing force from a symmetrical direction, so that the male connector 2 is subjected to balanced force, improving the overall connection stability. After the male connector 2 is inserted into the female connector 1, the rotating turntable 35 causes the arc-shaped sliding hole 36 on it to move the sliding rod 34. The sliding rod 34 then moves the locking block 33 along the rectangular sliding hole on the mounting plate 32 and locks it onto the locking protrusion ring 31, thus quickly fixing the female connector 1 and the male connector 2. When disassembling, the turntable 35 is rotated in the opposite direction to disengage the locking block 33 from the locking protrusion ring 31, allowing the male connector 2 to be pulled out. Quick fixing and separation can be achieved without tightening the threads, solving the problem of inconvenient disassembly of traditional connectors and improving operating efficiency.

[0027] Working principle: After the male connector 2 is inserted into the female connector 1, the rotating turntable 35 moves the sliding rod 34 by rotating the arc-shaped sliding hole 36 on it. The sliding rod 34 moves the locking block 33 along the rectangular sliding hole on the mounting plate 32 and locks it on the locking protrusion ring 31, thus achieving quick fixation of the female connector 1 and the male connector 2. When disassembling, the turntable 35 is rotated in the opposite direction to make the locking block 33 disengage from the locking protrusion ring 31, and the male connector 2 can be pulled out. Quick fixation and separation can be achieved without tightening the threads.

[0028] Please see Figure 1-5Based on the above embodiments, in another embodiment of this utility model, a limiting mechanism 4 is provided on the female connector 1. The limiting mechanism 4 includes: a fixing plate 41, which is connected to the outer wall of the female connector 1. A spring 42 is connected to the left side of the fixing plate 41, a pull block 43 is connected to the left end of the spring 42, and a plug rod 44 is connected to the right side of the pull block 43. The plug rod 44 is slidably connected to the fixing plate 41. A slot is provided on the left side of the turntable 35, and the right end of the plug rod 44 is inserted into the slot. The spring 42 pushes the right end of the plug rod 44 into the slot on the left side of the turntable 35, limiting the rotation of the turntable 35 and ensuring that the locking block 33 and the locking protrusion ring 31 are stably engaged. When the turntable 35 needs to be rotated, the pull block 43 is pulled to stretch the spring 42 and drive the plug rod 44 out of the slot to unlock it, avoiding the locking block 33 from loosening due to vibration or accidental contact, and enhancing the connection safety.

[0029] A sealing mechanism 5 is provided on the female connector 1 and the male connector 2. The sealing mechanism 5 includes an annular sealing plate 51, which is connected to the left end of the male connector 2. A sealing groove is opened at the right end of the female connector 1. The annular sealing plate 51 is inserted into the sealing groove. An annular sealing gasket 52 is connected to the left side of the annular sealing plate 51. The outer wall of the annular sealing gasket 52 abuts against the inner wall of the sealing groove. When the male connector 2 is inserted into the female connector 1, the annular sealing plate 51 is inserted into the sealing groove. At the same time, the annular sealing gasket 52 undergoes elastic deformation due to compression, filling the gap of the sealing groove, preventing fluid leakage, and improving the safety performance of the connector.

[0030] Working principle: The spring 42 pushes the right end of the insertion rod 44 into the slot on the left side of the turntable 35, restricting the rotation of the turntable 35 and ensuring that the locking block 33 and the locking protrusion ring 31 are stably engaged. When the turntable 35 needs to be rotated, the pull block 43 is pulled to stretch the spring 42 and drive the insertion rod 44 out of the slot to unlock. When the male connector 2 is inserted into the female connector 1, the annular sealing plate 51 is inserted into the sealing groove. At the same time, the annular sealing gasket 52 undergoes elastic deformation due to compression, filling the gap of the sealing groove and preventing fluid leakage.

The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
