Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to a liquid-cooled quick-connect connector with a one-handed unlocking mechanism. Background Technology

[0002] With the widespread application of liquid cooling technology in data centers, new energy equipment and other fields, liquid-cooled quick-connect fittings, as core components of pipeline connections, have become a key requirement for ease of operation, connection stability and sealing reliability.

[0003] Existing liquid-cooled quick-connect connectors mostly employ a two-hand unlocking mechanism or require additional tools for assembly and disassembly. In densely installed equipment scenarios, limited operating space leads to low maintenance efficiency. Furthermore, some connectors have simple locking structures, resulting in unstable connections, the risk of accidental detachment, and insufficient sealing performance, which can cause coolant leakage and affect the normal operation of the liquid cooling system. Therefore, a liquid-cooled quick-connect connector with a one-hand unlocking mechanism is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the above problems by proposing a liquid-cooled quick-connect connector that is compact, can be operated with one hand, has a secure lock, and is reliably sealed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liquid-cooled quick-connect connector with a one-handed unlocking mechanism, comprising a connector body, a plug body, and a limiting lock sleeve; the plug body is pluggable and detachable inside the connector body, and its front end outer side is provided with multiple sealing rings to achieve a sealing fit; the rear end of the plug body is integrally formed with a No. 1 threaded pipe connector, and an annular groove is formed on the outer circumference of the rear end; the front end of the connector body is integrally formed with a No. 2 threaded pipe connector; the limiting lock sleeve rotates around the axis of the plug body by means of an annular protrusion on its inner rear end rotating with the annular groove of the plug body; the front end of the limiting lock sleeve is sleeved outside the rear end of the connector body, and through a combination of rotation and axial movement, the connector body and the plug body can be locked or unlocked with one hand.

[0006] Preferably, the connector body includes a connector main body, telescopic springs, and limiting blocks; four rectangular grooves are evenly distributed circumferentially in the middle of the outer side of the connector main body; eight telescopic springs are provided in total, with two springs in each group corresponding to the two ends of a rectangular groove, and the telescopic direction of the springs is set radially along the connector main body; four limiting blocks are provided in total, and the upper ends of the two sets of telescopic springs in each rectangular groove are welded and fixed to a limiting block. The telescopic springs are used to provide radial elastic restoring force for the limiting blocks, so that the limiting blocks can automatically return to the protruding state after being radially pressed into the rectangular grooves.

[0007] Preferably, the top surface of the limiting block has a segmented structure, with curved inclined surfaces at both ends and a curved horizontal surface in the middle. A groove opening is provided on the curved horizontal surface in the middle, and the groove opening is used to form a snap-fit ​​engagement with the limiting lock sleeve.

[0008] Preferably, the inner rear end of the limiting lock sleeve is provided with an integrally formed annular protrusion, and the front end is provided with four through holes that correspond one-to-one with the limiting blocks; one end of each through hole is provided with a locking head that fits into the groove opening on the top surface of the limiting block; multiple rings are integrally formed in the middle of the outer side of the limiting lock sleeve, and multiple transverse anti-slip grooves are evenly formed on the outer circumference of each ring to improve the grip friction when operating with one hand.

[0009] Preferably, the outer side of the portion of the plug body inserted into the connector body has multiple sealing rings evenly distributed along the axial direction, and the sealing rings are used to achieve a seal between the plug body and the connector body.

[0010] Preferably, the locking process between the connector body and the plug body is divided into two steps: the first step of locking: the limiting block protrudes from the rectangular groove of the connector body under the action of the telescopic spring, and the protruding part is inserted into the through hole of the limiting lock sleeve to achieve initial positioning; the second step of locking: the limiting lock sleeve is rotated so that the locking head in its through hole is inserted into the groove opening on the top surface of the limiting block to form axial limiting and complete locking.

[0011] Preferably, the unlocking process is completed by one-handed operation. The specific steps are as follows: Pinch the outer ring of the limiting lock sleeve with one hand and rotate it to disengage the locking head in the through hole from the groove opening on the top surface of the limiting block, thus releasing the second step of locking; While holding the ring, pull the limiting lock sleeve axially backward. The inner wall of the through hole of the limiting lock sleeve presses against the curved inclined surfaces at both ends of the limiting block, causing the limiting block to overcome the elastic force of the telescopic spring and radially press into the rectangular groove of the connector body, thereby disengaging from the through hole of the limiting lock sleeve and releasing the first step of locking; At this time, the plug body can be pulled out of the connector body to complete the overall unlocking.

[0012] The beneficial effects of this utility model are as follows: With the design of this liquid-cooled quick-connect connector, a one-handed operation unlocking mechanism of "rotation + axial movement" is adopted, and the anti-slip groove design on the outside of the limit lock sleeve makes the operation convenient and efficient, and adapts to the rapid maintenance needs in dense installation environments. Through a two-step locking structure (the through hole of the limit block and the limit lock sleeve for initial positioning, and the axial positioning of the card head and the groove opening), combined with the elastic reset effect of the telescopic spring, the connection is highly stable and prevents the connector from accidentally falling off when the liquid cooling system is working. The front end of the plug body is equipped with multiple sealing rings, which, together with the threaded pipe fitting, provide a double seal to effectively prevent coolant leakage and improve the sealing performance and reliability of the liquid cooling system. Each component has a compact structure and a clear assembly logic. No additional tools are required for disassembly and assembly, reducing the difficulty of operation. At the same time, the components are highly versatile, making it easy to maintain and replace them later. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only a part of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] See Figure 1-2 As shown, the connector body 1, as the core receiving component of the connector, provides a reference channel for the insertion and assembly of the plug body 2. Its integrally formed No. 2 threaded pipe connector 5 is used to fix the connection with the external liquid cooling pipeline to realize the input or output passage of coolant. At the same time, the connector body 1 cooperates with the limit block 103 through the internal telescopic spring 102 to provide a locking support point for the limit lock sleeve 3, ensuring a stable connection between the connector body 1 and the plug body 2.

[0017] The connector body 101 is the core structural component of the connector body 1. The four rectangular grooves on its outer side are used to accommodate the telescopic spring 102 and the limiting block 103, providing installation space and motion guidance for both. At the same time, the internal tubular channel is adapted to the insertion and assembly of the plug body 2, forming the core flow channel for coolant transmission.

[0018] Eight telescopic springs 102 are provided in total, with each pair forming a group. They are mounted radially at both ends of the rectangular groove along the joint body 101. Their core function is to provide radial elastic restoring force for the limiting block 103: when the limiting block 103 is not subjected to external force, the telescopic spring 102 extends and pushes the limiting block 103 out of the rectangular groove to achieve engagement with the limiting lock sleeve 3; when unlocking, after the limiting block 103 is squeezed, the telescopic spring 102 contracts and stores elastic force. After the external force is released, it can push the limiting block 103 back to its original position to prepare for the next locking.

[0019] Four limit blocks 103 are provided, which are welded and fixed to each set of telescopic springs 102. The segmented structure of the top surface (with curved inclined surfaces at both ends, a curved horizontal surface in the middle, and a groove opening) is adapted to the locking action of the limit lock sleeve 3: the part protruding into the rectangular groove can be inserted into the through hole of the limit lock sleeve 3 to achieve initial positioning, and the groove opening in the middle cooperates with the locking head of the limit lock sleeve 3 to form axial limiting and complete locking; when unlocking, its curved inclined surface is convenient for the inner wall of the through hole of the limit lock sleeve 3 to be squeezed, so that the limit block 103 can be smoothly retracted into the rectangular groove and the lock is released.

[0020] See appendix Figure 1-4 As shown, the plug body 2 serves as the insertion and connection component of the connector. Its front end can be plugged into the connector body 101. The multiple sealing rings on its outer side achieve a sealing fit with the connector body 101 to prevent coolant leakage. The integrated No. 1 threaded pipe connector 4 at the rear end is used to connect with external liquid cooling pipes to form a complete coolant transmission circuit. At the same time, the annular groove at the rear end of the plug body 2 provides a rotation assembly reference for the limit lock sleeve 3, so that the limit lock sleeve 3 can rotate stably around its axis, ensuring the smooth realization of locking or unlocking actions.

[0021] The sealing ring is located on the outer front end of the plug body 2 and is evenly distributed in multiple rings along the axial direction. Its core function is to fill the assembly gap between the plug body 2 and the connector body 101, and achieve a tight fit between the two through elastic sealing, preventing the coolant from leaking from the assembly gap during transmission and ensuring the sealing reliability of the liquid cooling system.

[0022] The limiting lock sleeve 3, as the core actuator of the one-handed unlocking mechanism, has an annular protrusion at its inner rear end that rotates in conjunction with the annular groove of the plug body 2, enabling rotational freedom around the axis of the plug body 2. The four through holes at the front end correspond one-to-one with the limiting block 103, and the locking heads within the through holes fit into the groove openings of the limiting block 103, forming a locking structure. The outer middle ring and transverse anti-slip groove enhance grip friction during one-handed operation, facilitating the operator to lock or unlock the connector body 1 and plug body 2 through a combination of rotation and axial movement, thus meeting the rapid maintenance needs in densely installed environments. See appendix Figure 1As shown, the No. 1 threaded pipe fitting 4 is integrally formed with the plug body 2 and is used for the fixed connection between the plug body 2 and the external liquid cooling pipe. The threaded sealing fit ensures the sealing of the pipe connection and prevents coolant leakage. At the same time, it provides an interface for coolant to flow into or out of the plug body 2.

[0023] No. 2 threaded pipe fitting 5: The fitting body 1 is integrally formed and is used for the fixed connection between the fitting body 1 and the external liquid cooling pipe. The threaded sealing fit ensures the sealing of the pipe connection and avoids coolant leakage. At the same time, it provides an interface for coolant to flow into or out of the fitting body 1. Together with No. 1 threaded pipe fitting 4, it forms a complete liquid cooling transmission path.

[0024] The operation process of this utility model is as follows: Connection and locking operation: Hold the No. 1 threaded pipe connector 4 at the rear end of the plug body 2, align the front end of the plug body 2 with the tubular channel inside the connector body 101 of the connector body 1, and insert it smoothly along the axial direction until the multi-ring sealing ring at the front end of the plug body 2 is tightly fitted with the inner wall of the connector body 101.

[0025] During insertion, the limiting block 103 in the rectangular groove of the connector body 101 is squeezed by the outer wall of the plug body 2, overcomes the radial elastic restoring force of the telescopic spring 102, and radially retracts into the rectangular groove; when the plug body 2 is inserted into place, the limiting block 103 automatically protrudes from the rectangular groove under the elastic force of the telescopic spring 102, and its protruding part is locked into the corresponding through hole at the front end of the limiting lock sleeve 3, completing the first step of preliminary positioning.

[0026] Hold the ring in the middle of the outer side of the limiting lock sleeve 3 with one hand (using the horizontal anti-slip groove to increase grip friction), and rotate the limiting lock sleeve 3 clockwise until the clip in the through hole of the limiting lock sleeve 3 is engaged in the groove opening on the top surface of the limiting block 103, forming an axial limit, completing the second step of complete locking. At this time, the connector body 1 and the plug body 2 are firmly connected, and liquid cooling pipe docking can be performed.

[0027] The external liquid cooling pipes are fixed to threaded pipe joints 4 and 5 respectively through threaded sealing to form a complete liquid cooling transmission path.

[0028] Unlocking and separating operation: Pinch the ring in the middle of the outer side of the limit lock sleeve 3 with one hand, and rotate the limit lock sleeve 3 counterclockwise to make the latch in the through hole disengage from the groove opening on the top surface of the limit block 103, thus releasing the second step of locking.

[0029] While holding the limiting lock sleeve 3, pull the limiting lock sleeve 3 backward along the axis. The inner wall of the through hole of the limiting lock sleeve 3 presses against the curved inclined surfaces at both ends of the limiting block 103, so that the limiting block 103 overcomes the elastic force of the telescopic spring 102 and radially retracts into the rectangular groove of the connector body 101, thereby disengaging from the through hole of the limiting lock sleeve 3 and releasing the first step of locking.

[0030] Pull the limiting lock sleeve 3 backward continuously, causing the plug body 2 to be pulled out axially from the inside of the connector body 101, completing the complete separation of the connector body 1 and the plug body 2; after releasing the limiting lock sleeve 3, the limiting block 103 returns to the initial state of the protruding rectangular groove under the elastic force of the telescopic spring 102, preparing for the next connection lock.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art should understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of protection of the present invention is defined by the appended claims and their equivalents.
