[0002] Pipe quick connectors are widely used in various industrial, agricultural, medical and scientific research fields. Their main function is to facilitate the quick connection and disconnection of pipes to improve work efficiency and reduce maintenance costs. Most traditional pipe quick connectors, like the quick connector assembly with publication number CN118009125A, are manually operated to achieve connection and separation through rotation, push-pull or other mechanical methods.

[0003] However, this mode of operation may cause inconvenience and low efficiency in certain specific environments, such as when frequent connection and disconnection are required, or in some automated equipment with high sealing requirements. It may even cause loose sealing due to human factors, causing leakage problems. In addition, with the development of intelligent liquid storage equipment (such as the water tank of a mobile intelligent nursing toilet that requires frequent water replenishment), the automation requirements for pipe joints are getting higher and higher. The existing manually operated joints do not have an automatic separation function, cannot adapt to the rapid response of automated equipment and unmanned application scenarios, and are difficult to meet the needs of automated refilling systems. Therefore, it is urgent to design a new type of quick connector that can be linked with the control system to achieve automatic docking and separation. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments described in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The embodiment of the utility model provides a pipeline quick connector, including a female connector and a male connector plugged with the female connector, wherein the female connector is integrated with a locking mechanism and an automatic locking and separation mechanism to achieve quick connection and separation. Specifically:

[0029] like Figures 1 to 4 As shown, the male connector includes a fixed housing 1 and a male body 2 disposed in the fixed housing 1. The fixed housing 1 is evenly provided with fixing holes 101 in the circumferential direction, and the male connector can be installed and fixed on the mobile water supply equipment by bolts. The outer wall of the end (i.e., the plug-in end) of the male body 2 used for plugging with the female body 4 is circumferentially provided with a fixing ring groove 201 and a sealing ring groove 202. The sealing ring groove 202 is located on the outer wall of the plug-in end of the male body 2 in front of the fixed ring groove 201. A sealing ring 203 is installed in the sealing ring groove 202, so that the male body 2 can be in close contact with the plug-in cavity 401 of the female body 4 to prevent leakage of liquid in a static state. The end of the male body 2 opposite to the plug-in end (i.e., the male pipe interface 204 used to fix the water injection pipe 10) is threadedly installed with a male back cover 206 to facilitate the installation and replacement of the water injection pipe 10. In addition, in order to further improve the sealing between the water injection pipe 10 and the pipe quick connector, a male pipe claw 205 is provided between the male back cover 206 and the male pipe connector. The male pipe claw 205 is conical (i.e., the outer diameter gradually decreases toward the water injection pipe 10). By tightening the male back cover 206, the water injection pipe 10 and the male pipe interface 204 are tightly fitted.

[0030] like Figures 1 to 6As shown, in this embodiment, the female connector is installed on the water injection equipment to replenish water for the mobile water equipment, and the female connector includes a fixing frame 3, a female head body 4, a locking mechanism and an automatic locking and separation mechanism. Among them, the fixing frame 3 serves as a mounting base for other components. In order to ensure that the pipeline quick connector maintains good mechanical properties under various environments and facilitate the installation and maintenance of components, the fixing frame 3 includes two fixing plates, which are arranged in parallel by bolts, and the fixing plates are provided with mounting holes. The female head body 4 is fixed between the two fixing plates through the mounting holes. One end of the female head body 4 is provided with a trumpet-shaped plug-in cavity 401 that expands outward, so as to guide the insertion of the male connector, ensure the precise alignment of the male head during docking, and prevent dislocation and damage. The other end of the female seat body is provided with a female pipe interface 402 for fixing the water injection pipe 10. The female pipe interface 402 and the wooden pipe interface are threadedly installed with a female back cover 404. A female pipe claw 403 is provided between the female back cover 404 and the male pipe joint. The outer diameter of the female pipe claw 403 gradually decreases in a conical shape toward the water injection pipe 10, so that the water injection pipe 10 and the female pipe interface 402 are connected more tightly and firmly.

[0031] like Figures 4 to 7 As shown, as a preferred embodiment, the locking mechanism includes a locking hole 405, a locking ball 5 and a sliding lock sleeve 6. There are multiple locking holes 405, which are evenly arranged on the plug-in cavity 401 of the female connector in the circumferential direction and correspond to the position of the fixed ring groove 201. The ball locks are movably installed in the locking holes 405 in a one-to-one correspondence and can float up and down along the locking holes 405. Correspondingly, a transition slope 207 is formed in the fixed ring groove 201 to facilitate the ejection of the ball lock when unlocking. The sliding lock sleeve 6 is coaxially sleeved outside the plug-in cavity 401 and can slide circumferentially along the female connector body 4. The inner wall of the sliding lock sleeve 6 is provided with an annular locking block 601, and the annular locking block 601 includes a guiding inclined surface 6011 inclined at a certain angle and a locking surface 6012 parallel to the pipeline axis. When the male connector and the female connector are plugged in, part of the ball locks will fall into the fixed ring groove 201 of the male head body 2 under the action of gravity. At this time, by sliding the sliding lock sleeve 6, the remaining ball locks can be pushed into the fixed ring groove 201 through the guiding inclined surface 6011. When the locking surface 6012 is located on the outside of the ball lock, the ball lock can be pressed and fixed to prevent it from floating up and down, thereby completing the locking after the male connector and the female connector are plugged in.

[0032] like Figure 4As shown, in this embodiment, the automatic locking and separation mechanism includes a connecting plate 7 and a driving device, the connecting plate 7 is fixedly connected to the sliding lock sleeve 6, and the driving device is used to drive the connecting plate to translate in a direction parallel to the axis of the pipe joint. Specifically in this embodiment, a threaded hole is provided on the connecting plate 7, and the driving device includes a screw rod 8 and a driving motor 9, the screw rod 8 is threadedly matched with the threaded hole, and is coaxially connected to the driving motor 9 through a coupling, and the driving motor 9 can drive the screw rod 8 to rotate when receiving a locking or separation signal remotely, so as to drive the connecting plate 7 to move horizontally, thereby controlling the sliding lock sleeve 6 to automatically lock and separate without manual intervention.

[0033] refer to Figures 4 to 6 The specific working process of the pipeline quick connector provided by the embodiment of the utility model is as follows:

[0034] Docking process: When the water-using equipment needs to be replenished with water, the male body 2 is inserted straightly along the inner wall of the female body 4 under the guidance of the trumpet-shaped insertion cavity 401, so that the flow passages of the male body 2 and the female body 4 are aligned, and the fluid passages are connected. At this time, when the ball lock above the insertion cavity 401 falls into the fixed ring groove 201 of the male body 2 under the action of gravity, the annular locking block 601 on the sliding lock sleeve 6 is pushed by the driving motor 9 to move horizontally in a positive direction, and the ball lock is completely stuck into the fixed ring groove 201 through the guiding inclined surface 6011 and locked through the locking surface 6012, so as to prevent the male connector and the female connector from separating during the water injection process.

[0035] Separation process: When the water-using equipment needs to separate the joint after filling the water, the annular locking block 601 on the sliding lock sleeve 6 is pushed by the driving motor 9 to move horizontally in the opposite direction, so that the annular locking block 601 is away from the fixed ring groove 201, avoiding the floating space of the ball lock, and releasing the lock. At this time, the male joint is withdrawn from the plug-in cavity 401 of the female joint to complete the separation.
