The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Please refer to FIG. 1 and FIG. 2 , the utility model provides a fast and easy push type joint 10 for connecting pipes 20 . The quick and easy push joint 10 includes a joint 11 , a pressure ring 13 , a water stop ring 15 and a screw 17 . The surface of the pipe 20 is provided with an annular fixing groove 200, the pressure ring 13 and the water stop ring 15 are pre-assembled in the joint 11, and the pipe 20 is assembled on the joint 11 and fixed by screws 17.

The joint 11 is tubular and has a through connecting hole 111 along its axial direction. The pipe wall of the joint 11 is provided with a screw hole 113 and an opening 117 along the radial direction of the joint 11. The screw hole 113 and the opening 117 pass through the connecting hole 111. In this embodiment, the screw hole 113 and the opening 117 are opened in the same section perpendicular to the axial direction of the joint 11 , and the opening is in the shape of a bar. It can be understood that the opening can be set in other shapes. A first groove 110 and a second groove 112 are formed on the inner side of the pipe wall of the joint 11 . In this embodiment, the first groove 110 is disposed near the end of the joint 11 , and the second groove 112 is disposed near the middle of the joint 11 . The first groove 110 is provided with a first side wall 115 inclined at a certain angle to the axial direction of the joint 11 and a second side wall 116 perpendicular to the axial direction of the joint. The first side wall 115 is arranged near the end of the joint 11, and the second The side wall 116 is disposed in the middle of the joint 11 relative to the first side wall 115 . It can be understood that the joint 11 can adopt various shapes, and the axial directions of the connecting holes 111 can be perpendicular to each other or at a certain angle, such as 90 degrees, 45 degrees and so on. The joint 11 can also be provided with a plurality of connecting holes 111 to connect a plurality of pipes 20 , such as three-way, four-way and so on. The size of the connection hole 111 of the joint 11 can also be set corresponding to the size of the connected pipe 20 . The inner side of the pipe wall of the joint 11 is also provided with a stop portion 118 protruding radially along the joint 11 , and the stop portion 118 is arranged in the middle of the pipe 11 to prevent the pipe 20 from being inserted too deeply. In this embodiment, the first groove 110 , the second groove 112 and the stop portion 118 of the connector 11 are sequentially arranged along a direction away from the end of the connector 11 .

The pressure ring 13 is annular and has a notch 131 thereon. The water stop ring 15 is annular, and the inner wall of the water stop ring 15 is provided with a water stop portion 151 protruding toward the center of the water stop ring 15 along the radial direction of the water stop ring 15. The water stop portion 151 is used to strengthen the water stop of the water stop ring 15 Effect. In this embodiment, the water stop portion 151 is hemispherical. It can be understood that the number of the water stop portion 151 can be set according to the size of the pipe 20 and the joint 11 , and the shape of the water stop portion 151 can be set as required. The water stop ring 15 is made of elastic material. The inner diameter of the pressure ring 13 is smaller than the diameter of the connection hole 111 of the joint 11 and the outer diameter of the pipe material 20, the inner diameter of the water stop ring 15 is smaller than the diameter of the connection hole 111 of the joint 11 and the outer diameter of the pipe material 20, the pressure ring 13 and the water stop ring 15 The outer diameter is larger than the diameter of the connecting hole 111 of the joint 11 .

When using the quick and easy push joint 10 to connect the pipe 20, the pressure ring 13 is arranged in the first groove 110 of the joint 11, the water stop ring 15 is arranged in the second groove 112 of the joint 11, and the pipe 20 is arranged along the axis of the joint 11. Extending into the connecting hole 111 of the joint 11 , the pressure ring 13 moves axially along the joint 11 under the push of the pipe material 20 and abuts against the second side wall 116 of the first groove 110 . The pipe 20 continues to extend into the joint 11. Since the pressure ring 13 is provided with a gap 131, the pressure ring 13 is sleeved on the pipe 20 under the resistance of the second side wall 116 of the joint 11 and the pipe 20, and is set in the fixing groove of the pipe 20. When 200 passes through the pressure ring 13, the pressure ring 13 will be locked in the fixing groove 200 of the pipe 20 and make a sound. At the same time, the pipe material 20 is passed through the water stop ring 15, and resists the water stop portion 151 provided on the inner diameter of the water stop ring 15. The water stop ring 15 is filled in the second groove 112 of the joint 11, and the water stop ring 15 is elastic. Deform and fill between the joint 11 and the pipe 20 . After the pressure ring 13 is locked in the fixing groove 200 of the pipe 20 , the pipe 20 is pulled back in a direction away from the joint 11 , and the pressure ring 13 is held against the first side wall 115 of the joint 11 . Since the pressure ring 13 is provided with a notch 131 , the pressure ring 13 is further fastened to the fixing groove 200 of the pipe 20 under the action of resisting. The screw 17 passes through and is connected to the screw hole 113 of the joint 11 . The screw 17 resists the pressure ring 13 along the radial direction of the pressure ring 13 to further fix the pressure ring 13 and the pipe 20 relative to the joint 11 . It can be understood that when the quick and easy push joint 10 is actually used, when the fluid pressure in the pipe 20 increases, the pressure of the pressure ring 13 against the first side wall 115 of the joint 11 will also increase, and the pressure ring 13 will Furthermore, it is fastened to the fixing groove 200 of the pipe material 20 , so when the fluid pressure in the pipe material 20 is higher, the quick-and-easy push joint 10 is safer to use.

The quick and easy push joint 10 of the present utility model is also provided with a dismounting part. When disassembling the quick and easy push joint 10, the screw 17 is removed first, and then the pipe 20 and the pressure ring 13 sleeved on the pipe 20 are stretched inward. , until the pressure ring 13 is against the second side wall 116 in the joint 11 ; insert the detachment part 12 into the opening 117 of the joint 11 and insert the detachment part 12 between the pressure ring 13 and the first side wall 115 . During the process of pulling away the pipe material 20, the dismantling part 12 presses against the pressure ring 13. Since the pressure ring 13 cannot be held against the first side wall 115, the pressure ring 13 is lightly buckled in the fixing groove 200 of the pipe material 20, and can be easily moved along. The pipe 20 is pulled away from the joint 11 , thereby separating the pipe 20 from the joint 11 . In this embodiment, the detachment part 12 is in the shape of a sheet, and it can be understood that the detachment part 12 can be set in other shapes corresponding to the opening 117 and usage needs.

The utility model seals the pipe material 20 through the water stop ring 15 to prevent leakage. And the pipe 20 is fixed relative to the joint 11 through the screw 17 and the pressure ring 13 to ensure the connection reliability of the fast and easy push joint 10 . In addition, the fast and easy push-in joint 10 does not need to be threaded on the pipe material 20 in advance, which saves the production cost of installation time and is fast and effective in use.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions. For a person of ordinary skill in the technical field to which the utility model belongs, without departing from the concept of the utility model, some simple deduction or substitutions can also be made, which should be regarded as belonging to the protection scope of the utility model.
