Description

Technical Field

[0001] This invention relates to the field of pipe connection technology, and in particular to a quick-connect structure for water purification equipment pipes. Background Technology

[0002] Water purification equipment refers to equipment that produces purified water. It is mainly used in homes, offices, medical facilities, and industrial settings. With the increasing popularity of vehicle-mounted water purification equipment, its core components are connected by pipes, and the reliability of these pipe connections directly affects the overall performance of the equipment.

[0003] Currently, the pipe connections of vehicle-mounted water purification equipment mostly adopt traditional connection methods, mainly including three types: threaded connection, flange connection, and ordinary snap-fit ​​quick connection. While threaded and flanged connections offer a certain level of strength, installation and disassembly require specialized tools such as wrenches and screwdrivers, making the process cumbersome and inefficient. While ordinary snap-fit ​​quick-connects solve the efficiency problem, they typically rely on a single snap-fit ​​or elastic element for locking and fixing. During vehicle operation, continuous multi-frequency vibrations act on the pipe connection points, and existing quick-connect structures generally lack specific vibration-resistant designs. Over time, the cumulative vibrations can lead to snap-fit ​​loosening, resulting in leaks, pipe misalignment, or even detachment, failing to meet the stable operation requirements of water purification equipment during vehicle travel. Furthermore, existing connection structures typically lock and limit the pipe at both ends individually. Pipes may experience unilateral stress due to vehicle bumps or wiring pulling. Lacking a stress-linking protection design, existing structures only passively limit the pipe on one side when under unilateral stress. Vibrations amplify this stress, causing stress concentration at the other side of the connection, leading to loosening.

[0004] Therefore, there is an urgent need to provide a quick-connect structure for pipe fittings that can improve vibration resistance and avoid unilateral stress concentration. Summary of the Invention

[0005] Therefore, it is necessary to provide a quick-connect structure for water purification equipment pipe fittings, which aims to solve the problem of pipe fittings falling off from the connecting structure or stress concentration on one side due to continuous vibration after the existing pipe fittings are connected.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick connection structure for water purification equipment pipe fittings, comprising: a connector for connecting the opposite ends of two pipe fittings, wherein locking elements are provided inside both ends of the connector.

[0007] The quick-connect structure of the water purification equipment pipe fittings also includes a clamping unit. Two clamping units are provided and symmetrically connected to both ends of the connector. The clamping unit includes a mounting part that can be detachably installed at the end of the connector. Multiple clamping parts for pulling and then clamping the pipe fitting are installed on the mounting part.

[0008] The clamping part includes a rotating component rotatably connected to the mounting part, and a pressure arc plate is installed on the side of the rotating component near the connector.

[0009] The quick-connect structure of the water purification equipment pipe fittings also includes a locking unit. The locking unit is located on the outside of the connector and is used to lock the two clamping units. The locking unit includes locking sleeves located on both sides of the connector and locked together. The end wall of the locking sleeve has a connecting hole. Multiple pushing parts are connected to the inner side of the annular wall of the locking sleeve. During the locking process of the two locking sleeves, the multiple pushing parts on both sides are driven to push the corresponding rotating parts to rotate, so that the two pipe fittings move away from the connector at the same time. The locking part performs a first-level clamping limit on the pipe fittings, and then the pressing arc plate performs a second-level clamping limit on the pipe fittings.

[0010] Preferably, the mounting part includes a mounting ring detachably mounted on the end of the connector. Multiple connecting rods are mounted on the end of the mounting ring away from the connector. The ends of the multiple connecting rods away from the mounting ring are jointly mounted on a hinged ring frame, which is simultaneously hinged to multiple rotating parts.

[0011] Preferably, the rotating component consists of a fan-shaped plate and a lever, and a rubber pad is laid on the arc-shaped surface of the fan-shaped plate.

[0012] Preferably, the clamping part further includes a reinforcing rod that is fixedly connected to both the actuating rod and the outer arc surface of the clamping arc plate.

[0013] Preferably, the locking unit further includes two symmetrically distributed locking parts, which are simultaneously connected to two locking sleeves, and the locking parts lock and limit the two locking sleeves.

[0014] Preferably, the pushing part includes two pushing plates that are symmetrically distributed on the left and right and installed on the inner side of the annular wall of the locking sleeve. The two pushing plates are provided with pushing surfaces on opposite sides of one end near the axis of the locking sleeve, and the two pushing plates are located on both sides of the corresponding actuating rod.

[0015] Preferably, the locking part includes two splicing plates respectively installed at opposite ends of the two locking sleeves, one splicing plate having a snap-fit ​​sleeve installed at the end away from the locking sleeve, the snap-fit ​​sleeve having a limit through hole on the side wall away from the connector, and the other splicing plate having a snap-fit ​​groove.

[0016] Preferably, the locking part further includes a snap-fit ​​block slidably connected in the snap-fit ​​groove, a return spring is installed between the snap-fit ​​block and the snap-fit ​​groove, and an inclined surface one and an inclined surface two are respectively opened on the end of the snap-fit ​​block away from the connector.

[0017] Preferably, the inner arc surface of the pressing arc plate is covered with a rubber pad.

[0018] Preferably, the splicing plate is detachably connected to a limiting component.

[0019] In summary, the present invention has the following beneficial technical effects: 1. The locking unit used in the present invention cooperates with two clamping units to lock and fix two pipe fittings at the same time, effectively improving the efficiency of pipe fitting docking. Moreover, the locking unit has strong force linkage. When any pipe fitting is pulled by an external force, the force will be transmitted to the corresponding locking sleeve, causing it to move relative to the sleeve, thereby increasing the clamping strength of the clamping part on the pipe fitting. This achieves the effect of synchronously increasing the clamping strength on both sides when one side of the pipe fitting is subjected to force, greatly reducing the risk of detachment caused by stress concentration at the connection of the pipe fitting on one side.

[0020] 2. In the process of driving the two clamping units by the locking unit of the present invention, the pipe fitting can be driven to cooperate with the locking part and the connector to realize the first-level clamping and limiting of the pipe fitting by the locking part. After the locking unit drives the two clamping units, the clamping unit performs the second-level clamping and limiting of the pipe fitting. The double clamping and limiting effectively avoids the pipe fitting from falling off due to factors such as long-term vibration and water flow impact, and ensures the stability of the water purification equipment operation.

Detailed Implementation

[0030] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] See Figures 1-3 A quick-connect structure for water purification equipment pipe fittings includes a connector 1 for connecting the opposite ends of two pipe fittings. Locking elements 10 are provided inside both ends of the connector 1. The locking elements 10 have an annular structure, with a triangular protrusion on the outer annular surface at the inner end of the connector 1. A clamping protrusion is provided on the inner annular surface of the locking elements 10. Multiple openings are provided on the locking elements 10 at the inner end of the connector 1. Guide grooves corresponding to the triangular protrusions are provided on the inner annular surface of the connector 1 near both ends (this is prior art).

[0032] See Figure 1 , Figure 3 and Figure 5 The quick-connect structure of the water purification equipment pipe fittings also includes two clamping units 2 that are symmetrically connected to both ends of the connector 1. The clamping unit 2 includes a mounting part 20 that can be detachably installed at the end of the connector 1. The mounting part 20 includes a mounting ring 200 that can be detachably installed at the end of the connector 1. Multiple connecting rods 201 are installed at the end of the mounting ring 200 away from the connector 1. The ends of the multiple connecting rods 201 away from the mounting ring 200 are jointly installed with a hinged ring frame 202.

[0033] In actual operation, before the two pipe fittings are connected, two mounting rings 200 are respectively fitted onto both ends of the connector 1 and fixedly connected to the connector 1 by existing buckles (not shown in the figure). The mounting rings 200 limit the hinge ring frame 202 through multiple connecting rods 201. It should be noted that the distance between the multiple connecting rods 201 is relatively large, allowing the operator to move the locking part 10 with their fingers.

[0034] See Figure 1 , Figure 3 , Figure 4 and Figure 5 The mounting part 20 is equipped with multiple clamping parts 21 for first pulling and then clamping the pipe fitting. Each clamping part 21 includes a rotating part 210 rotatably connected to the mounting part 20. The rotating part 210 consists of a fan-shaped plate and a lever. The hinge ring frame 202 is simultaneously hinged to multiple levers. A rubber pad is laid on the arc surface of the fan-shaped plate. A pressing arc plate 211 is installed on the side of the rotating part 210 near the connector 1. A rubber pad is laid on the inner arc surface of the pressing arc plate 211. The clamping part 21 also includes a reinforcing rod 212 that is fixedly connected to both the lever and the outer arc surface of the pressing arc plate 211.

[0035] In actual operation, after the mounting ring 200 is installed at the end of the connector 1, the hinge ring frame 202 simultaneously fixes the positions of multiple rotating parts 210. In the initial state, multiple levers are tilted away from the connector 1, and the ends of multiple fan-shaped plates away from the connector 1 are in a vertical state.

[0036] See Figures 1-3 The quick-connect structure of the water purification equipment pipe fittings also includes a locking unit 3 located on the outside of the connector 1 and used to lock the two clamping units 2. The locking unit 3 includes locking sleeves 30 located on both sides of the connector 1 and locked together. The end wall of the locking sleeve 30 has a connecting hole.

[0037] See Figure 2 , Figure 3 and Figure 6 The locking unit 3 further includes two symmetrically distributed locking parts 32, which are connected to two locking sleeves 30 at the same time, and the locking parts 32 lock and limit the two locking sleeves 30. The locking part 32 includes two splicing plates 320 respectively installed at opposite ends of the two locking sleeves 30. One splicing plate 320 is equipped with a snap-fit ​​sleeve 321 at the end away from the locking sleeve 30. The splicing plate 320 is detachably connected to a limiting member 326 by means of thread engagement.

[0038] In actual operation, the splicing plates 320 on the two locking sleeves 30 have the same structure but different lengths. After the two mounting rings 200 are installed at both ends of the connector 1, the two locking sleeves 30 are respectively fitted onto the outside of the two hinge ring frames 202. The splicing plate 320 on one locking sleeve 30 is inserted into the snap sleeve 321 at the end of the other corresponding splicing plate 320. The snap sleeve 321 guides the insertion of the two splicing plates 320. Then, the limiting member 326 is threadedly connected to the splicing plate 320. The limiting member 326 is a threaded rod. The connector 1 blocks the lateral movement of the limiting member 326, thereby preventing the locking sleeve 30 from separating from the connector 1 after being fitted.

[0039] See Figure 1 , Figure 3 , Figure 6 and Figure 7 The inner side of the annular wall of the locking sleeve 30 is connected to a plurality of pushing parts 31. The pushing parts 31 include two pushing plates 310 that are symmetrically distributed on the left and right and installed on the inner side of the annular wall of the locking sleeve 30. The two pushing plates 310 are provided with pushing surfaces 311 on opposite sides of the ends of the two pushing plates 310 that are close to the axis of the locking sleeve 30. The two pushing plates 310 are located on both sides of the corresponding actuating rod. The end of the actuating rod away from the axis of the locking sleeve 30 extends beyond the end of the pushing plate 310 that is close to the axis of the locking sleeve 30.

[0040] In actual operation, during the locking process of the two locking sleeves 30, multiple pushing parts 31 on both sides simultaneously drive the corresponding rotating parts 210 to rotate, causing the two pipe fittings to move simultaneously away from the connector 1. The locking part 10 performs a first-level clamping and limiting of the pipe fittings, and then the pressing arc plate 211 performs a second-level clamping and limiting of the pipe fittings (such as...). Figure 7As shown in the diagram, specifically: the two pipe fittings to be connected are inserted into the two locking members 10 through the connecting holes in the middle of the two locking sleeves 30, and then through the locking members 10 into the connector 1. The rubber ring inside the connector 1 seals the pipe fittings. Then, the two locking sleeves 30 are pushed simultaneously. The two locking sleeves 30 simultaneously drive multiple push plates 310 on both sides of the connector 1 to move towards the connector 1. The moving push plates 310 push the corresponding actuating rods through the pushing surface 311. The multiple actuating rods move towards the connector 1 and drive multiple fan-shaped plates to rotate away from the connector 1. The multiple fan-shaped plates drive the pipe fittings to move away from the connector 1 a certain distance through the rubber pads laid on the arc surface, until the multiple fan-shaped plates drive multiple pressing arc plates. Rubber pad 211 is attached to the pipe fitting. During this process, the moving pipe fitting drives the locking part 10 to move. The triangular protrusion on the locking part 10 cooperates with the guide groove to drive the clamping protrusion on the inner ring surface of the locking part 10 to press and clamp the pipe fitting, thereby achieving the first-level clamping limit of the pipe fitting. Multiple clamping arc plates 211 on the same side form a circle that matches the diameter of the pipe fitting. Then, the locking sleeve 30 is pushed. Multiple clamping arc plates 211 continuously apply pressure to rubber pad 2, thereby increasing the clamping strength of the pipe fitting and achieving the second-level clamping limit of the pipe fitting. This effectively increases the connection strength after the pipe fitting is connected, and prevents the pipe fitting from falling off due to long-term vibration after being connected to the connecting structure. The reinforcing rod 212 increases the bending resistance of the clamping arc plate 211.

[0041] See Figure 6 The snap-fit ​​sleeve 321 has a limiting through hole 322 on its side wall away from the connector 1, and another splicing plate 320 has a snap-fit ​​groove 323.

[0042] See Figure 1 , Figure 3 , Figure 5 and Figure 6 The locking part 32 also includes a locking block 324 that is slidably connected in the locking groove 323. A return spring 325 is installed between the locking block 324 and the locking groove 323. The end of the locking block 324 away from the connector 1 is provided with an inclined surface one and an inclined surface two.

[0043] In actual operation, when the two locking sleeves 30 are spliced ​​together, the two locking sleeves 30 drive the splicing plates 320 on both sides to move closer to each other. The splicing plate 320 with the snap-fit ​​groove 323 drives the snap-fit ​​block 324 to move towards the snap-fit ​​sleeve 321 through the snap-fit ​​groove 323. The inclined surface of the snap-fit ​​block 324 contacts the end of the snap-fit ​​sleeve 321 and is subjected to force, thereby moving into the snap-fit ​​groove 323 and squeezing the return spring 325 until the snap-fit ​​groove 323 moves to the limiting through hole 322. The compressed return spring 325 drives the snap-fit ​​block 324 to return to its original position. The snap-fit ​​block 324 enters the limiting through hole 322, realizing the splicing of the two splicing plates 320, and thus realizing the overall connection of the two locking sleeves 30. At this time, the multiple pressing arc plates 211 apply pressure to the rubber pad 2 to realize the function of clamping the pipe.

[0044] When connecting two pipe fittings, simply insert both fittings into connector 1 and perform a two-stage clamping and limiting process by splicing the two locking sleeves 30. This not only reduces the steps of fixing each fitting separately to connector 1 but also increases the connection strength between the fittings and connector 1. Furthermore, after splicing the two locking sleeves 30, any fitting on either side can apply tension to the two locking sleeves 30, causing them to tend to move. As the force on the fitting increases, the corresponding locking element 10 gradually increases its clamping strength, while the locking sleeve 30 on the other side... Multiple push plates 310 increase the thrust on the lever, causing the sector plate to increase the pressure on the pipe fitting, thereby strengthening the clamping strength of the pipe fitting on the other side. This achieves the function of increasing the clamping strength of both pipe fittings when one side of the pipe fitting is under force, further improving the connection strength between the two pipe fittings and the connector 1, and preventing the pipe fittings from falling off the connector 1. If the pipe fittings need to be replaced, simply press the two snap-fit ​​blocks 324. The inclined surface of the snap-fit ​​block 324 facilitates the snap-fit ​​block 324 to enter the snap-fit ​​sleeve 321 during the separation of the two locking sleeves 30, thus facilitating the separation of the two locking sleeves 30. The operation is simple and convenient, and the practicality is high.
