Description

Technical Field

[0001] The invention relates to the technical field of pipeline connection, in particular to a water purifier pipeline connector. Background Art

[0002] The water purifier pipe connector is an important part used to connect the water purifier to the household water supply pipe, ensuring that the water can flow smoothly through the water purification system for purification. Choosing the right connector is crucial to ensure the normal operation of the water purifier and avoid problems such as water leakage.

[0003] The existing water purifier pipe connector mainly consists of four parts: an outer shell, a rubber ring installed inside the outer shell, a buckle, and a clamping ring for limiting the buckle. The clamping ring is a semi-ring structure. The water purifier pipe and the connector are sealed by the rubber ring and the buckle, and the clamping ring limits the buckle to prevent the buckle from being accidentally loosened.

[0004] However, the above connector still has the following shortcomings during use: 1. The existing connector is only connected by a snap buckle, and the connection strength between the water purifier pipe and the connector needs to be improved. When the single snap buckle is aged or damaged, the locking ability of the snap buckle on the water purifier pipe will be weakened, and then the water purifier pipe is prone to loosening and leaking.

[0005] 2. The existing connector must be limited by a clamping ring, but the clamping ring is designed to be independently detachable and easily fall off due to external force. Once the clamping ring is lost, the buckle can no longer be limited, and the connection firmness and sealing of the connector and the water purifier pipe will be reduced. Summary of the invention

The inclined surface of the pressure ring close to the center of the shell abuts against the protrusion, and the inclined surface away from the center of the shell abuts against the second sleeve ring.

[0013] In one possible implementation, the end of the elastic internal resistance sheet away from the corresponding ring 2 is inclined toward the center of the shell, and the inner wall of the through hole close to the center of the shell is provided with an inclined surface with the same inclination angle as the elastic internal resistance sheet, and the inner wall away from the center of the shell is fixedly connected with a push block for expanding the elastic internal resistance sheet.

[0014] In one possible implementation, a plurality of elastic outer resistance sheets are evenly installed circumferentially on the outer ring wall of the second sleeve ring near one end of the shell center, and the end of the elastic outer resistance sheet away from the corresponding second sleeve ring is inclined in a direction away from the shell center, and the second sleeve ring is slidably installed in the inside of the second ring groove, and the second ring groove is installed with a rubber ring located on the side of the elastic outer resistance sheet away from the shell center.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] See also Figure 2 , Figure 3 and Figure 5 The primary locking mechanism 2 includes a left-right slidably mounted inside the shell 1 and symmetrically mounted on the left and right sides. A clamping fastening component 22 for sealing and clamping the water purifier pipe 5 is installed on the side of the ring 21 close to the center of the shell 1. A plurality of through holes 23 evenly distributed in the circumferential direction are opened on the ring 21. A blocking component 25 is fixedly connected to the end of the ring 21 away from the center of the shell 1. The inner diameter of the ring 21 is equal to the outer diameter of the water purifier pipe 5.

[0034] See also Figure 2 , Figure 3 and Figure 6 The secondary locking mechanism 3 includes a second ring 31 slidably mounted on the outside of the first ring 21, and a plurality of elastic inner blocking sheets 32 are evenly mounted on the inner ring wall of the second ring 31 at one end close to the center of the shell 1, which penetrate the inner side of the through hole 23 and perform secondary clamping on the water purifier pipe 5. A blocking component 2 34 is installed at one end of the second ring 31 away from the center of the shell 1.

[0035] See also Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 The limiting mechanism 4 includes a rotating ring 41 which is rotatably mounted on the outside of the shell 1 and is symmetrical on both sides. A plurality of L-shaped stoppers 42 for limiting the blocking component 1 25 and the blocking component 2 34 are evenly connected to the side of the rotating ring 41 away from the center of the shell 1. A rotating component 43 is installed inside the rotating ring 41.

[0036] See also Figure 2 , Figure 3 and Figure 4 The shell 1 is provided with an alignment groove 11, an annular groove 12 and an annular groove 2 14 which are coaxial with the shell 1 and distributed along the axial direction. The alignment groove 11, the annular groove 12 and the annular groove 2 14 are symmetrically distributed about the center of the shell 1, and the alignment groove 11 and the annular groove 12 are located between the left and right annular grooves 14. The alignment groove 11 cooperates with the end of the water purifier pipe 5, and the side of the alignment groove 11 away from the center of the shell 1 is connected to the annular groove 12.

[0037] When connecting the water purifier pipe 5, the water purifier pipe 5 is inserted into the sleeve ring 21, and the end of the water purifier pipe 5 is inserted into the alignment groove 11 until it can no longer be inserted.

[0038] See also Figure 2 , Figure 3 , Figure 4 and Figure 5The clamping fastening assembly 22 includes a plurality of buckles 221 fixedly connected to one end of the ring 21 close to the center of the shell 1 and evenly distributed circumferentially, a rib 222 is fixedly connected to one side of the buckle 221 close to the axis of the shell 1, a convex block is integrally formed on the outer wall of the buckle 221 close to the center of the shell 1, a rubber ring 223 for sealing the water purifier pipe 5 is installed in the annular groove 12, and the rubber ring 223 is located on the side of the buckle 221 close to the center of the shell 1.

[0039] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 A pressing ring 13 located between the annular groove 12 and the annular groove 2 14 is fixedly connected inside the shell 1. The cross-section of the pressing ring 13 is trapezoidal and is located on the side of the protrusion away from the center of the shell 1. The inclined surface of the pressing ring 13 close to the center of the shell 1 contacts the protrusion, and the inclined surface away from the center of the shell 1 contacts the second ring 31.

[0040] When the end of the water purifier pipe 5 is inserted into the alignment groove 11, the rubber ring 223 is sleeved on the outside of the water purifier pipe 5, and the rubber ring 223 is deformed. The rubber ring 223 is used to seal the gap between the shell 1 and the water purifier pipe 5 to form a sealing area 1, thereby improving the connection sealing performance between the water purifier pipe 5 and the connector; when assembling the connector, first assemble the ring 231 and the installation ring 21, and then insert the ring 231 and the installation ring 21 into the shell 1 as a whole. During this process, the buckle 221 and the protrusion as a whole will be blocked by the pressure ring 13 when entering the pressure ring 13 and tilted toward the axis direction of the ring 21, causing deformation. When installed in place, the protrusion on the buckle 221 will contact with the inclined surface of the pressing ring 13, but the protrusion on the buckle 221 will not contact with the end of the rubber ring 223. Under the action of its own elastic force, the deformation of the buckle 221 and the protrusion as a whole is reduced compared with before, but it is still inclined toward the axis direction of the ring 21. After inserting the water purifier pipe 5, the rib 222 is clamped on the outside of the water purifier pipe 5 to prevent the water purifier pipe 5 from loosening from the inside of the shell 1, thereby improving the firmness of the connection between the shell 1 and the water purifier pipe 5, and further forming a sealing area 2 at the same time, thereby improving the connection sealing between the water purifier pipe 5 and the connector.

[0041] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 The end of the elastic inner resistance sheet 32 ​​away from the corresponding ring 2 31 is inclined toward the center of the shell 1, and the inner wall of the through hole 23 close to the center of the shell 1 is provided with an inclined surface with the same inclination angle as the elastic inner resistance sheet 32, and the inner wall away from the center of the shell 1 is fixedly connected with a push block 24 for expanding the elastic inner resistance sheet 32.

[0042] The inner diameter of the elastic inner resistance piece 32 is smaller than the outer diameter of the water purifier pipe 5. When the end of the water purifier pipe 5 is inserted into the alignment groove 11, the elastic inner resistance piece 32 is deformed due to the outward pushing force given by the water purifier pipe 5. The elastic inner resistance piece 32 is clamped on the outside of the water purifier pipe 5 by utilizing its own resilience, thereby performing secondary locking of the water purifier pipe 5, further improving the firmness of the locking of the elastic inner resistance piece 32, and at the same time forming a third sealing area, further improving the connection sealing of the water purifier pipe 5 and the connector.

[0043] When the water purifier pipe 5 is to be disassembled, the ring 21 is pushed to move toward the center of the shell 1. The ring 21 will drive the buckle 221 to move toward the center of the shell 1, so that the pressure ring 13 is separated from the protrusion. At this time, the buckle 221 will release the clamping lock on the water purifier pipe 5 under the action of its own rebound force. At the same time, the ring 21 will drive the pushing block 24 to move together during the movement. The pushing block 24 is used to support the elastic inner resistance sheet 32 ​​outward, so that the elastic inner resistance sheet 32 ​​releases the clamping of the water purifier pipe 5, so as to quickly and conveniently release the lock on the water purifier pipe 5. Finally, the water purifier pipe 5 is pulled out of the shell 1 to be disassembled.

[0044] If the water purifier pipe 5 is pulled outward, with the buckle 221 and the elastic inner resistance sheet 32 ​​clamping the water purifier pipe 5, the ring 1 21 and the buckle 221 will move together with the water purifier pipe 5. At this time, the buckle 221 and the protrusion as a whole will further tilt toward the axial direction of the ring 1 21 under the action of the inclined surface of the pressure ring 13 to further clamp the water purifier pipe 5. At the same time, the elastic inner resistance sheet 32 ​​will also be further clamped on the water purifier pipe 5 under the action of the inner wall of the through hole 23. Therefore, when the water purifier pipe 5 is pulled outward, the water purifier pipe 5 will not loosen.

[0045] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A plurality of elastic outer resistance sheets 33 are evenly installed on the outer ring wall of the second ring 31 near the center of the shell 1. The end of the elastic outer resistance sheet 33 away from the corresponding second ring 31 is inclined in the direction away from the center of the shell 1. The second ring 31 is slidably installed in the second ring groove 14. A rubber ring 35 is installed in the second ring groove 14 on the side of the elastic outer resistance sheet 33 away from the center of the shell 1.

[0046] When assembling the connector, first combine the primary locking mechanism 2 and the secondary locking mechanism 3 together. Take the assembly of the primary locking mechanism 2 and the secondary locking mechanism 3 at the right end of the shell 1 as an example. Specifically: put the ring 231 from left to right on the outside of the buckle 221. At this time, the buckle 221 will deform inwardly under the extrusion of the ring 23. When the buckle 221 conflicts with the elastic internal resistance sheet 32, the elastic internal resistance sheet 32 ​​will deform outwardly under the extrusion force of the buckle 221 until the elastic internal resistance sheet 32 ​​corresponds to the through hole 23. At this time, the elastic internal resistance sheet 32 ​​will recover inwardly under the action of its own elastic force and be inserted into the inner side of the through hole 23, and be located on the left side of the push block 24.

[0047] After the primary locking mechanism 2 and the secondary locking mechanism 3 are assembled, the rubber ring 2 35 is sleeved on the sleeve ring 2 31, and then the rubber ring 1 223 is installed in the ring groove 12 inside the shell 1, and then the assembled primary locking mechanism 2 and the secondary locking mechanism 3 are pushed together into the inside of the shell 1. When pushing, the buckle 221 first enters the shell 1, and then deforms inwardly under the action of the pressure ring 13, and then the elastic outer resistance piece 33 and the rubber ring 2 35 are squeezed and deformed at the port of the shell 1. When the elastic outer resistance piece 33 and the rubber ring 2 35 are completely entered into the ring groove 14, the elastic outer resistance piece 33 and the rubber ring 2 35 are squeezed and deformed. The sheet 33 and the rubber ring 35 will recover under the action of their own elastic force. At this time, the elastic outer resistance sheet 33 and the rubber ring 35 will be limited inside the ring groove 14, thereby preventing the ring 31 from falling off. The blocking component 25 is restricted by the shell 1 and cannot move into the shell 1. At the same time, the protrusion on the buckle 221 will contact the inclined surface of the pressure ring 13, but the protrusion on the buckle 221 does not contact the end of the rubber ring 223. Under the action of their own elastic force, the deformation of the buckle 221 and the protrusion as a whole is reduced compared with before, but it is still inclined toward the axis direction of the ring 21.

[0048] After the ring 2 31 is installed in the shell 1, the elastic outer resistance piece 33 is limited between the rubber ring 2 35 and the inner wall of the ring groove 2 14, which preliminarily prevents the ring 2 31 from moving inside the shell 1 and causing the elastic inner resistance piece 32 to be loosely clamped. At the same time, the rubber ring 2 35 also seals the gap between the shell 1 and the ring 2 31 to form a sealing area 4, further improving the connection sealing of the water purifier pipe 5 and the connector.

[0049] See also Figure 2 , Figure 5 and Fig. 9The blocking assembly 25 includes a baffle 251 fixedly connected to the end of the ring 21 away from the center of the shell 1. The baffle 251 is located outside the shell 1. A plurality of slide grooves 252 are evenly arranged on the side of the baffle 251 close to the center of the shell 1. The baffle 251 is also provided with a rectangular through groove 253 corresponding to the slide groove 252 and connected to the side end of the slide groove 252. The slide groove 252 is slidably matched with one end of the L-shaped stopper 42 parallel to the radial direction of the shell 1.

[0050] See also Figure 2 , Figure 5 , Figure 6 and Fig. 9 The blocking component 34 includes a baffle 341 fixedly connected to the side of the ring 31 away from the center of the shell 1, the baffle 341 is located outside the shell 1, and an arcuate through groove 342 corresponding to the slide groove 252 is opened on the baffle 341. The L-shaped block 42 passes through the arcuate through groove 342 and cooperates with the slide groove 252. The baffle 341 is also provided with a rectangular through groove 343 corresponding to the arcuate through groove 342 and connected to the side end of the arcuate through groove 342. The arcuate through groove 342 and the corresponding rectangular through groove 343 form an L-shaped structure. One end of the L-shaped block 42 parallel to the radial direction of the shell 1 is limited between the baffle 341 and the baffle 251, and the rectangular through groove 343 and the corresponding rectangular through groove 253 are arranged opposite to each other.

[0051] See also Figure 1 , Figure 7 and Figure 8 The rotating assembly 43 includes a plurality of fixed blocks 431 fixedly connected to the inside of the rotating ring 41 and evenly distributed circumferentially, a plurality of fixed blocks 433 are evenly installed circumferentially on the outer ring wall of the shell 1, the fixed blocks 433 are slidably installed inside the rotating ring 41, and a spring sheet 432 is fixedly connected between the fixed blocks 431 and the corresponding fixed blocks 433.

[0052] In the initial state, one end of the L-shaped stopper 42 parallel to the radial direction of the shell 1 is located on the side of the slide groove 252 away from the rectangular through groove 253. At this time, the spring sheet 432 is in a compressed state, and the spring sheet 432 gives the rotating ring 41 an elastic force to rotate counterclockwise, so that the L-shaped stopper 42 presses against the inner wall of the slide groove 252.

[0053] See also Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9When assembling the assembled primary locking mechanism 2 and secondary locking mechanism 3 with the housing 1, first manually rotate the rotating ring 41 counterclockwise to make the fixed block 1 431 compress the spring sheet 432, and then align the L-shaped stopper 42 with the rectangular through groove 2 343 and the rectangular through groove 1 253 in advance, and manually limit the rotating ring 41 so that it does not rotate temporarily, and then move the collar 1 21 and the collar 2 31 toward the center of the housing 1 and insert them into the interior of the housing 1, and the baffle 2 341 and the baffle 1 251 move toward the L-shaped stopper 42. After the assembly is completed, the L-shaped stopper 42 passes through the rectangular through groove 2 343 and the end portion enters the rectangular through groove 1 253, but the end surface of the end portion of the L-shaped stopper 42 entering the rectangular through groove 1 253 is aligned with the end portion of the L-shaped stopper 42 entering the rectangular through groove 1 253. The slide groove 252 is flush, and then the rotating ring 41 is loosened. Under the action of the rebound force of the spring sheet 432, the rotating ring 41 drives the L-shaped stopper 42 to rotate clockwise, so that the end of the L-shaped stopper 42 parallel to the radial direction of the shell 1 slides into the slide groove 252. Finally, the L-shaped stopper 42 is located in the end of the arc groove 342 away from the rectangular groove 2 343 and is tightly pressed against the inner wall of the arc groove 342 at this end. At this time, the end of the L-shaped stopper 42 parallel to the radial direction of the shell 1 is stuck between the baffle 2 341 and the baffle 1 251. The L-shaped stopper 42 is used to block and limit the baffle 1 251 to prevent the baffle 1 251 from being accidentally touched, causing the ring 1 21 to move toward the center of the shell 1, so that the clamping and fastening assembly 22 releases the lock on the water purifier pipe 5.

[0054] When it is necessary to release the limit of the L-shaped stopper 42 on the baffle 251, the rotating ring 41 is rotated counterclockwise to make the end of the L-shaped stopper 42 parallel to the radial direction of the shell 1 slide from the slide groove 252 to be aligned with the rectangular through groove 253. The L-shaped stopper 42 no longer blocks the baffle 251. Then, the baffle 251 can be pushed toward the center of the shell 1, and the L-shaped stopper 42 will pass through the rectangular through groove 253, thereby facilitating the unlocking of the clamping fastening assembly 22 and the elastic inner resistance sheet 32.
