[0001] This utility model relates to a PVC composite high-pressure hose, belonging to the field of high-pressure hose technology. Background Technology

[0002] In the connection structure of high-pressure hoses, traditional connection methods often suffer from inadequate locking structure design. In existing technologies, some high-pressure hoses rely solely on a single locking structure to fix the positioning ring during connection. Under long-term conditions of high-pressure fluid impact or vibration, this structure is prone to insecure locking, leading to leakage. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a PVC composite high-pressure hose, which solves the problem that in the prior art, some high-pressure hoses rely solely on a single locking structure to fix the positioning ring during connection. This structure is prone to insecure locking under long-term high-pressure fluid impact or vibration conditions.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution: a PVC composite high-pressure hose, comprising two pipe bodies, each pipe body having a connector fixedly mounted thereon, each connector having a clamp fixedly mounted thereon, a sealing structure for sealing the two pipe bodies being provided between the connectors, a first positioning ring and a second positioning ring being provided on each connector, each first positioning ring and the second positioning ring having a positioning groove, the clamp being able to abut against the positioning groove, each first positioning ring and the second positioning ring having a mounting plate fixedly mounted thereon, the mounting plate having a locking structure for locking the first positioning ring and the second positioning ring.

[0005] By adopting the above technical solution, the two connectors are first brought together, and the connection is sealed by a sealing structure to prevent leakage. Then, the first and second positioning rings are fitted onto the connection of the connectors, causing the positioning grooves of the first and second positioning rings to abut against the clamping plate. The positioning grooves then push the clamping plate closer to each other. When the mounting plates on the first and second positioning rings abut against each other, the connection of the two connectors is completed. Subsequently, the mounting plate is locked by a locking structure, thereby locking the first and second positioning rings. Through the double fixing and sealing of the clamping plate and the first and second positioning rings, the pipe body can maintain a more secure locking state under long-term high-pressure fluid impact or vibration conditions, extending the service life of the device and reducing the risk of leakage.

[0006] The present invention is further configured such that: the sealing structure includes a sealing groove, a sealing ring and a sealing gasket, the sealing groove is opened on the connector, the sealing ring is disposed inside the sealing groove, the sealing gasket is fixedly disposed with the sealing ring, and the sealing gasket is located between the two clamps and can abut against the clamps.

[0007] By adopting the above technical solution, the sealing ring is placed inside the sealing groove, and then the connector drives the clamp to squeeze the sealing gasket, so that the sealing gasket tightly fills the gap between the connectors, further enhancing the sealing effect.

[0008] The present invention is further configured such that: a guide groove is provided on the connector head, and guide blocks are fixedly provided on both the first positioning ring and the second positioning ring, and the guide blocks can abut against the guide groove.

[0009] By adopting the above technical solution, when installing the first positioning ring and the second positioning ring, the guide block is driven to insert into the guide groove, which prevents the first positioning ring and the second positioning ring from rotating during use and ensures the stability of the device.

[0010] The present invention is further configured such that: the locking structure includes a threaded hole, a bolt and a limiting part, the threaded hole passes through the mounting plate, the bolt passes through the threaded hole and is threadedly connected to the threaded hole, and the limiting part is provided on the connector head and is used to limit the mounting plate.

[0011] The present invention is further configured such that: the limiting part includes a fixed block, a sliding groove, a sliding plate, a limiting rod, a limiting groove, and a lever plate; the fixed block is fixedly mounted on the connector head; the sliding groove is horizontally opened on the fixed block; the sliding plate is slidably mounted inside the sliding groove; the limiting rod is fixedly mounted on the sliding plate; the limiting groove is horizontally opened on the mounting plate at one end facing the fixed block; the end of the limiting rod facing the limiting groove can extend to the outside of the fixed block and be inserted into the limiting groove; one end of the sliding plate extends to the outside of the fixed block and is fixedly mounted on the lever plate.

[0012] The present invention is further configured such that a spring is fixedly installed between the side of the sliding plate away from the limiting rod and the inner wall of the sliding groove.

[0013] By adopting the above technical solution, the sliding plate is first driven by the toggle plate to slide inside the sliding groove, causing the sliding plate to move the limiting rod into the sliding groove. At the same time, the sliding plate compresses the spring during movement. When the two mounting plates abut, the limiting groove and the limiting rod are aligned. At this time, the toggle plate is released and the spring returns to its original position, pushing the sliding plate to slide inside the sliding groove. This causes the sliding plate to move the limiting rod towards the limiting groove, allowing the limiting rod to insert into the limiting groove, thus completing the first step of limiting the mounting plate. Then, the mounting plate is further limited by the action of bolts and threaded hole structures, thereby realizing the installation of the first positioning ring and the second positioning ring.

[0014] The beneficial effects of this utility model are as follows: First, the two connectors are brought together and sealed at the connection point through a sealing structure to prevent leakage. Then, the first and second positioning rings are fitted onto the connection point of the connectors, causing the positioning grooves of the first and second positioning rings to abut against the clamping plate. Subsequently, the positioning grooves push the clamping plate closer to each other. When the mounting plates on the first and second positioning rings abut against each other, the connection of the two connectors is completed. Then, the mounting plate is locked by a locking structure, thereby locking the first and second positioning rings. Through the double fixing and sealing of the clamping plate and the first and second positioning rings, the pipe body can maintain a more secure locking state under long-term high-pressure fluid impact or vibration conditions, extending the service life of the device and reducing the risk of leakage.

[0020] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] like Figures 1 to 3As shown, a PVC composite high-pressure hose includes two pipe bodies 1, each with a connector 2 fixedly mounted on it. Each connector 2 has a clamping plate 3 fixedly mounted on it, the clamping plate 3 being inclined. A sealing structure for sealing the two pipe bodies 1 is provided between the connectors 2. A first positioning ring 5 and a second positioning ring 6 are provided on each connector 2. The first positioning ring 5 and the second positioning ring 6 have identical structures. Positioning grooves 7 are provided on both the first positioning ring 5 and the second positioning ring 6, and the clamping plate 3 can abut against the positioning grooves 7. Mounting plates 8 are fixedly mounted on both the first positioning ring 5 and the second positioning ring 6, and the two mounting plates 8 can abut against each other. A locking structure for locking the first positioning ring 5 and the second positioning ring 6 is provided on the mounting plates 8.

[0022] like Figure 2 As shown, the sealing structure includes a sealing groove 1011, a sealing ring 1012, and a sealing gasket 1013. The sealing groove 1011 is horizontally opened on the connector 2. The sealing ring 1012 is disposed inside the sealing groove 1011. The sealing gasket 1013 is fixedly disposed with the sealing ring 1012. The sealing gasket 1013 is sleeved on the sealing ring 1012. The sealing gasket 1013 is located between the two clamping plates 3 and can abut against the clamping plates 3.

[0023] like Figure 1 and Figure 3 As shown, a guide groove 1021 is provided on the connector 2, and guide blocks 1022 are fixedly provided on the first positioning ring 5 and the second positioning ring 6. The guide blocks 1022 can abut against the guide groove 1021.

[0024] like Figure 3 As shown, the locking structure includes a threaded hole 1031, a bolt 1032, and a limiting part. The threaded hole 1031 passes through the mounting plate 8, the bolt 1032 passes through the threaded hole 1031 and is threadedly connected to the threaded hole 1031, and the limiting part is provided on the connector 2.

[0025] like Figure 4As shown, the limiting part includes a fixing block 1041, a sliding groove 1042, a sliding plate 1043, a limiting rod 1044, a limiting groove 1045, and a lever 1046. The fixing block 1041 is fixedly mounted on the connector 2. The sliding groove 1042 is horizontally opened on the fixing block 1041. The sliding plate 1043 is slidably mounted inside the sliding groove 1042. The limiting rod 1044 is fixedly mounted on the sliding plate 1043. The limiting groove 1045 is horizontally opened on the mounting plate 8 at one end facing the fixing block 1041. The end of the limiting rod 1044 facing the limiting groove 1045 can extend to the outside of the fixing block 1041 and be inserted into the limiting groove 1045. One end of the sliding plate 1043 extends to the outside of the fixing block 1041 and is fixedly mounted on the lever 1046. A spring 1051 is fixedly mounted between the side of the sliding plate 1043 away from the limiting rod 1044 and the inner wall of the sliding groove 1042. Spring 1051 is in a tensioned state when no force is applied.

[0026] First, the two connectors 2 are brought together to seal the connection point using a sealing structure to prevent leakage. Then, the first positioning ring 5 and the second positioning ring 6 are fitted onto the connection point of the connectors 2, causing the positioning rings 5 ​​and 6 to drive the positioning groove 7 to abut against the clamping plate 3. The positioning groove 7 then pushes the clamping plate 3 closer together. When the mounting plate 8 on the first positioning ring 5 and the second positioning ring 6 abuts, the connection of the two connectors 2 is completed. Subsequently, the mounting plate 8 is locked using a locking structure, thereby locking the first positioning ring 5 and the second positioning ring 6. Through the double fixing and sealing of the clamping plate 3 and the first positioning ring 5 and the second positioning ring 6, the pipe body 1 can maintain a more secure locking state under long-term high-pressure fluid impact or vibration conditions, extending the service life of the device and reducing the risk of leakage.

[0027] The sealing ring 1012 is placed inside the sealing groove 1011, and then the connector 2 drives the clamp 3 to squeeze the sealing gasket 1013, so that the sealing gasket 1013 tightly fills the gap between the connectors 2, further enhancing the sealing effect.

[0028] When installing the first positioning ring 5 and the second positioning ring 6, the guide block 1022 is inserted into the guide groove 1021 to prevent the first positioning ring 5 and the second positioning ring 6 from rotating during use, thus ensuring the stability of the device.

[0029] First, the sliding plate 1043 is driven to slide inside the sliding groove 1042 by the lever 1046, causing the sliding plate 1043 to move the limiting rod 1044 into the sliding groove 1042. At the same time, the sliding plate 1043 compresses the spring 1051 during its movement. When the two mounting plates 8 abut, the limiting groove 1045 is aligned with the limiting rod 1044. At this time, the lever 1046 is released and the spring 1051 is reset to push the sliding plate 1043 to slide inside the sliding groove 1042, causing the sliding plate 1043 to move the limiting rod 1044 towards the limiting groove 1045, so that the limiting rod 1044 is inserted into the limiting groove 1045, completing the first step of limiting the mounting plate 8. Then, the mounting plate 8 is further limited by the bolt 1032 and the threaded hole 1031, thereby realizing the installation of the first positioning ring 5 and the second positioning ring 6.
