Description

Technical Field

[0001] This utility model relates to the field of water supply pipe device technology, and in particular to a double-sealed PE water supply pipe. Background Technology

[0002] PE water supply pipes, or polyethylene water supply pipes, are a type of water supply pipe made primarily from polyethylene resin through extrusion molding. PE water supply pipes effectively resist chemical corrosion, ensuring the safety and stability of water quality. Their resistance to most domestic and industrial chemicals allows them to operate stably for extended periods in complex underground environments.

[0003] After installation, existing water supply pipes are usually fixed with multiple sets of bolts to ensure a stable and sealed connection. However, this fixing method requires the use of external tools to remove the bolts when the water supply pipe needs to be disassembled for maintenance, which is quite troublesome. To address the above problems, a double-sealed PE water supply pipe is needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a double-sealed PE water supply pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-sealed PE water supply pipe includes a first water supply pipe, a second water supply pipe inserted into one end of the first water supply pipe, a first trapezoidal sealing ring fixedly connected to the inner wall of the second water supply pipe, a second O-ring fixedly connected to the inside of the first water supply pipe, the surface of the first trapezoidal sealing ring pressing against the surface of the first water supply pipe, the surface of the second O-ring sealing ring pressing against the surface of the second water supply pipe, and a positioning and installation mechanism provided on the surface of the first water supply pipe.

[0007] Preferably, the positioning and installation mechanism includes an installation groove formed on the surface of the first water supply pipe, the inner wall of the installation groove having multiple grooves, and a knob rotatably connected to the inner wall of the installation groove.

[0008] Preferably, the surface of the knob is provided with a relief groove, the inner wall of the relief groove is fixedly connected to a first spring, the bottom end of the first spring is fixedly connected to a rounded corner protrusion, the rounded corner protrusion is slidably connected to the inner wall of the relief groove, and the rounded corner protrusion is adapted to the groove.

[0009] Preferably, the inner wall of the first water supply pipe is slidably connected to a slider, the surface of the second water supply pipe is provided with a slot, the slider is adapted to the slot, the inner wall of the first water supply pipe is provided with a reset groove, the inner wall of the reset groove is slidably connected to a connecting plate, and the surface of the connecting plate is fixedly connected to the surface of the slider.

[0010] Preferably, a second spring is fixedly connected to the inner wall of the reset groove, one end of the second spring is fixedly connected to the surface of the connecting plate, and the surface of the slider is in contact with the surface of the knob.

[0011] Preferably, the surface of the knob near the first water supply pipe is provided with an inclined surface and a horizontal surface.

[0012] The beneficial effects of this utility model are as follows:

[0013] When separating and disassembling the first and second water supply pipes, the torque of the rounded corner cam exceeds the resistance of the inner wall of the groove, causing the rounded corner cam to rise and release the rotation limit of the knob. The slider will rotate from its original contact rotation state with the horizontal surface to its contact state with the inclined surface. Under the action of the second spring, the slider rises and disengages from the slot, releasing the insertion state of the first and second water supply pipes, thus achieving quick disassembly of the first and second water supply pipes.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5 A double-sealed PE water supply pipe includes a first water supply pipe 1, a second water supply pipe 2 inserted into one end of the first water supply pipe 1, a first trapezoidal sealing ring 5 fixedly connected to the inner wall of the second water supply pipe 2, a second O-ring sealing ring 3 fixedly connected inside the first water supply pipe 1, the surface of the first trapezoidal sealing ring 5 pressing against the surface of the first water supply pipe 1, the surface of the second O-ring sealing ring 3 pressing against the surface of the second water supply pipe 2, and a positioning and installation mechanism provided on the surface of the first water supply pipe 1.

[0022] By setting the first trapezoidal sealing ring 5, the connection between the first water supply pipe 1 and the second water supply pipe 2 is sealed for the first time. By setting the second O-ring sealing ring 3, the connection between the first water supply pipe 1 and the second water supply pipe 2 is sealed for the second time. By setting the positioning and installation mechanism, the installation of the first trapezoidal sealing ring 5 and the second water supply pipe 2 is ensured to be stable. When it is necessary to disassemble and maintain the first trapezoidal sealing ring 5 and the second water supply pipe 2, it is quick and convenient.

[0023] In this utility model, the positioning and installation mechanism includes an installation groove 16 formed on the surface of the first water supply pipe 1, and a plurality of grooves 13 formed on the inner wall of the installation groove 16. A knob 9 is rotatably connected to the inner wall of the installation groove 16.

[0024] The mounting slot 16 provides space for the knob 9 to rotate and be installed, and the groove 13 allows it to be positioned in conjunction with the rounded corner convex shaft 11.

[0025] In this utility model, a relief groove 15 is provided on the surface of the knob 9. A first spring 10 is fixedly connected to the inner wall of the relief groove 15. A rounded corner convex shaft 11 is fixedly connected to the bottom end of the first spring 10. The rounded corner convex shaft 11 is slidably connected to the inner wall of the relief groove 15. The rounded corner convex shaft 11 is adapted to the groove 13.

[0026] By setting the relief groove 15, space is provided for the installation of the first spring 10 and the movement of the rounded corner convex shaft 11. The rounded corner convex shaft 11 is positioned by cooperating with the groove 13. When the rotational torque of the rounded corner convex shaft 11 breaks through the obstruction of the groove 13, the limit is released and the angle of the adjustment knob 9 is adjusted.

[0027] In this utility model, a slider 8 is slidably connected to the inner wall of the first water supply pipe 1, and a slot 4 is opened on the surface of the second water supply pipe 2. The slider 8 is adapted to the slot 4. A reset groove 17 is opened on the inner wall of the first water supply pipe 1, and a connecting plate 7 is slidably connected to the inner wall of the reset groove 17. The surface of the connecting plate 7 is fixedly connected to the surface of the slider 8.

[0028] By setting the slot 4, the connection between the first water supply pipe 1 and the second water supply pipe 2 remains stable after the slider 8 is inserted into the slot 4. By setting the reset groove 17, space is provided for the installation of the second spring 6 and the connecting plate 7.

[0029] In this utility model, a second spring 6 is fixedly connected to the inner wall of the reset groove 17, one end of the second spring 6 is fixedly connected to the surface of the connecting plate 7, and the surface of the slider 8 is in contact with the surface of the knob 9.

[0030] By setting a second spring 6, the connecting plate 7 and the slider 8 are driven to reset.

[0031] In this invention, the surface of the knob 9 near the first water supply pipe 1 is provided with an inclined surface 12 and a horizontal surface 14.

[0032] By setting an inclined surface 12, when the slider 8 contacts the inclined surface 12, the second spring 6 drives the slider 8 to rise, releasing the connection limit state between the first water supply pipe 1 and the second water supply pipe 2. By setting a horizontal surface 14, when the slider 8 contacts the horizontal surface 14, the slider 8 is driven to fall and be inserted into the slot 4 for positioning.

[0033] Working principle: Water flows into the first water supply pipe 1 and the second water supply pipe 2. The connection between the first water supply pipe 1 and the second water supply pipe 2 is doubly sealed by the first trapezoidal sealing ring 5 and the second O-ring sealing ring 3. When it is necessary to separate the first water supply pipe 1 and the second water supply pipe 2 for disassembly, the operator rotates the knob 9 in the mounting groove 16. The rotation of the knob 9 causes the rounded corner convex shaft 11 to be subjected to force. The rounded corner surface of the bottom end of the rounded corner convex shaft 11 is in contact with the inner wall of the groove 13. When the torsional force of the rounded corner convex shaft 11 exceeds the force of the groove 13... When the inner wall encounters resistance, the rounded corner convex shaft 11 rises, compressing the first spring 10 and shortening it. At this time, the limit of the knob 9 is released. When the slider 8 rotates from the contact rotation state of the horizontal surface 14 to the contact state of the inclined surface 12, the slider 8 and the connecting plate 7 are driven by the second spring 6 to rise, so that the surface of the slider 8 contacts the surface of the inclined surface 12. At this time, the slider 8 disengages from the slot 4, releasing the insertion state of the first water supply pipe 1 and the second water supply pipe 2. Through the above structure, the quick disassembly of the first water supply pipe 1 and the second water supply pipe 2 is achieved.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
