During this process, the air in the sealing ring will be drawn into the air cavity. When the sealing ring is fully contracted, the first fixing ring and the second fixing ring can be connected. After the connection is completed, the sliding block is slid in the opposite direction to drive the piston to send the air in the air cavity to the sealing ring through the air inlet. When the sealing ring is stuck in the annular groove, the connection between the first fixing ring and the second fixing ring can be sealed. Then the second slider is released, the second spring rebounds and drives the fixing rod to move inward through the second slider. When the fixing rod is inserted into the fixing hole, the sliding block can be fixed in the current position, thereby maintaining the expanded state of the sealing ring. This design can seal the connection between the hoses through the sealing ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The embodiment of the present application solves the problems in the prior art by providing a connecting ring for a PE hose.

[0026] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0027] The specific structure of this embodiment is as follows: Figures 1 to 5 As shown, a connecting ring for a PE hose comprises a hose 1, wherein two ends of the hose 1 are respectively fixedly connected with a first fixing ring 2 and a second fixing ring 3, and a connecting component 4 and a sealing component 5 are provided at the connection between the first fixing ring 2 and the second fixing ring 3.

[0028] In some examples, the connecting component 4 includes a mounting groove 41, a mounting block 42, a mounting hole 43 and a mounting rod 44. The mounting groove 41 is opened on the surface of one side of the second fixing ring 3. The mounting block 42 is fixedly connected to one side of the first fixing ring 2 and is adapted to the size of the mounting groove 41. The mounting hole 43 passes through the mounting block 42. The mounting rod 44 passes through the inner wall of one side of the mounting groove 41 and is adapted to the size of the mounting hole 43. The bottom of the mounting rod 44 is trapezoidal. The mounting block 42 is placed in the mounting groove 41, and then the mounting rod 44 is inserted into the mounting hole 43. At this time, the mounting block 42 can be fixed in the mounting groove 41, thereby completing the connection between the first fixing ring 2 and the second fixing ring 3.

[0029] In some examples, the connecting component 4 also includes a first slide groove 45, a first slider 46, a first spring 47 and a pull block 48. The first slide groove 45 is opened inside the second fixing ring 3 and is on both sides of the mounting rod 44. The first slider 46 is fixedly connected to both sides of the mounting rod 44 and is slidably connected to the first slide groove 45. The first spring 47 is fixedly installed inside the first slide groove 45 and its two ends are respectively fixedly connected to one side of the first slider 46 and the inner wall of one side of the first slide groove 45. The pull block 48 is fixedly connected to the outer end of the mounting rod 44. The pull block 48 is pulled upward to drive the mounting rod 44 to move upward and squeeze the first spring 47 through the first slider 46. The pull block 48 is released, and the first spring 47 rebounds to drive the mounting rod 44 to move downward through the first slider 46.

[0030] In some examples, the sealing assembly 5 includes an annular groove 51 and a sealing ring 52. The annular groove 51 is opened on the surface of the first fixing ring 2. The sealing ring 52 is fixedly installed on the surface of the second fixing ring 3 and is adapted to the size of the annular groove 51. The sealing ring 52 is made of rubber and is hollow inside. After the connection between the first fixing ring 2 and the second fixing ring 3 is completed, the sealing ring 52 is inserted into the annular groove 51. At this time, the sealing ring 52 is inflated to expand it, so as to seal the connection between the first fixing ring 2 and the second fixing ring 3.

[0031] In some examples, the sealing assembly 5 also includes a sliding groove 53, an air cavity 54, an air inlet 55, a piston 56, a connecting rod 57 and a sliding block 58. The sliding groove 53 is opened on the other side surface of the second fixing ring 3, the air cavity 54 is opened inside the second fixing ring 3 and is connected to one end of the sliding groove 53, the air inlet 55 is opened inside the second fixing ring 3 and its two ends are respectively connected to the air cavity 54 and the sealing ring 52, the piston 56 is slidably connected to the air cavity 54 and the size is adapted, one end of the connecting rod 57 is fixedly connected to the piston 56, the sliding block 58 is fixedly connected to the other end of the connecting rod 57 and is slidably connected to the sliding groove 53, and the sliding block 58 can be slid along the sliding groove 53 to drive the piston 56 to slide along the air cavity 54 through the connecting rod 57, thereby sending air to the sealing ring 52 or extracting air from the sealing ring 52 through the air inlet 55.

[0032] In some examples, the sealing assembly 5 also includes a second slide groove 59, a second slider 510, a fixing hole 511, a fixing rod 512 and a second spring 513. The second slide groove 59 is opened at the top of the sliding block 58, the second slider 510 is slidably connected to the second slide groove 59, the fixing hole 511 is opened on the surface of the second fixing ring 3 and is at the top of the sliding groove 53, the fixing rod 512 is fixedly connected to the second slider 510 and is adapted to the size of the fixing hole 511, the second spring 513 is fixedly installed inside the second slide groove 59 and its two ends are respectively fixedly connected to one side of the second slider 510 and the inner wall of one side of the second slide groove 59. The sliding block 58 can be fixed at the current position by inserting the fixing rod 512 into the fixing hole 511, and the position of the sliding block 58 can be adjusted by moving the fixing rod 512 out of the fixing hole 511.

[0033] In a specific application scenario, first pull the second slider 510 outward to drive the fixing rod 512 to move outward and squeeze the second spring 513. When the fixing rod 512 moves out of the fixing hole 511, slide the sliding block 58 to the left along the sliding groove 53 so that it drives the piston 56 to move synchronously through the connecting rod 57. During this process, the air in the sealing ring 52 will be sucked into the air cavity 54. When the sealing ring 52 is completely contracted, the mounting block 42 of the first fixing ring 2 is placed in the mounting groove 41 of the second fixing ring 3, and then the mounting block 42 is pushed inward. When the mounting block 42 contacts the mounting rod 44, since the bottom of the mounting rod 44 is trapezoidal, the mounting rod 44 will be pushed outward and squeeze the first spring 47 through the first slider 46. When the mounting block 42 moves to the mounting hole 43 and is below the mounting rod 44, the first spring 47 rebounds and drives the mounting rod 44 to move downward through the first slider 46. When the mounting rod 44 is inserted into the mounting hole 43, the mounting The block 42 is fixed in the mounting groove 41, thereby completing the connection between the first fixing ring 2 and the second fixing ring 3. At this time, the sliding block 58 is slid in the opposite direction to drive the piston 56 to send the air in the air cavity 54 to the sealing ring 52 through the air inlet 55. When the sealing ring 52 is inserted into the annular groove 51, the connection between the first fixing ring 2 and the second fixing ring 3 can be sealed. Then the second slider 510 is released, the second spring 513 rebounds and drives the fixing rod 512 to move inward through the second slider 510. When the fixing rod 512 is inserted into the fixing hole 511, the sliding block 58 can be fixed in the current position, thereby maintaining the expanded state of the sealing ring 52, and then maintaining the seal between the first fixing ring 2 and the second fixing ring 3. When the first fixing ring 2 and the second fixing ring 3 need to be removed, the pulling block 48 is pulled upward to drive the mounting rod 44 to move upward. When the mounting rod 44 is removed from the mounting hole 43, the first fixing ring 2 and the second fixing ring 3 can be removed by removing the mounting block 42 from the mounting groove 41.

[0034] By adopting the above technical solution, not only can the connection between the two groups of hoses be made more convenient and quick, thus effectively improving the work efficiency, but the connection between the hoses can also be sealed by the sealing ring.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the present invention.
