Description

Technical Field

[0001] The utility model relates to the technical field of water heating hardware, in particular to an anti-dropping copper insert for a PPR pipe elbow joint. Background Art

[0002] PPR pipe is a kind of plastic connecting pipe, mainly used in building drainage system or heating and other fields. It has the advantages of hygiene, environmental protection and long service life. It is mainly installed by hot melt and other connection methods. It is easy and reliable to install and is widely used.

[0003] When connecting PPR pipes, it is necessary to install copper inserts inside the PPR pipe elbow joints. The copper inserts mainly connect the PPR pipes to other pipes, which is convenient for the use of the pipes. When in use, the copper inserts are installed inside the connector by hot melting, and the product can be quickly pressed into the hole of the connector. During installation, the staff needs to process the copper inserts and insert them into the inside of the connecting pipe. During installation, the inside of the connecting pipe becomes soft due to heat and is connected to the block on the copper insert. However, during use, due to the influence of vibration and impact, the parts of the connection will fall off from each other after being vibrated, resulting in gaps, which affect the normal use of the copper inserts. For this reason, we provide a kind of anti-falling copper inserts for PPR pipe elbow joints to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 - Figure 5 As shown, the utility model provides a technical solution: an anti-falling copper insert for a PPR pipe elbow joint, comprising a connecting pipe 1, a base 2 is slidably connected inside the connecting pipe 1, a limiting ring 3 is fixedly connected to the outer surface of the base 2, a clamping ring 4 is fixedly connected to the outer surface of the limiting ring 3, the clamping ring 4 is an inward wedge-shaped structure, the outer surface of the clamping ring 4 is slidably connected to the outer surface of the connecting pipe 1, the clamping ring 4 and the limiting ring 3 are both installed at one end of the base 2, the position of the copper insert can be limited by the clamping ring 4 and the limiting ring 3, excessive installation of the copper insert inside the connecting pipe 1 can be avoided during installation, the clamping ring 4 is a wedge-shaped structure, the connection can be stably connected during installation, and the connecting pipe 1 has a sealing effect.

[0025] A fixing ring 1 5 is fixedly connected to the outer surface of the base 2, and a sealing ring 1 6 is installed inside the fixing ring 1 5. A fixing ring 2 7 is fixedly connected to the outer surface of the base 2, and a sealing ring 2 8 is installed inside the fixing ring 2 7. The sealing ring 1 6 and the sealing ring 2 8 are arranged separately. When the copper inlay is installed, the sealing ring 1 6 and the sealing ring 2 8 can seal the connection, and can form a stable seal with the softened parts inside the connecting pipe 1. The sealing ring 1 6 and the sealing ring 2 8 are elastic and can seal the space at the connection. The connection can be sealed by the elastic action of the sealing ring 1 6 and the sealing ring 2 8 to avoid water leakage after the internal gap appears.

[0026] A reinforcing ring 12 is fixedly connected to the outer surface of the base 2, a supporting ring 13 is fixedly connected to the outer surface of the base 2, a clamping plate 14 is fixedly connected to the outer surface of the supporting ring 13, and the clamping plate 14 is annularly arranged on the outside of the supporting ring 13. A supporting ring 2 15 is fixedly connected to the outer surface of the base 2, and a clamping plate 2 16 is fixedly connected to the outer surface of the supporting ring 2 15. The supporting ring 13 and the supporting ring 2 15 are distributed on the front and rear sides of the base 2, and the clamping plate 2 16 is annularly arranged on the outside of the supporting ring 2 15. The clamping plate 14 and the clamping plate 2 16 are arranged in the same direction, and the clamping plate 14 and the clamping plate 2 16 are both arranged horizontally, so that it is convenient for the staff to put the copper inlay into the interior of the connecting pipe 1 when installing the copper inlay. After the interior of the connecting pipe 1 is softened, it can be filled on both sides of the clamping plate 14 and the clamping plate 2 16. The action of the clamping plate 14 and the clamping plate 2 16 can prevent the base 2 from rotating after installation, ensure the stability of the base 2 when in use, and ensure the reliability of the connection of the base 2.

[0027] The interior of the fixed ring 27 is slidably connected with a movable ring 9, and the outer surface of the movable ring 9 is slidably connected with the interior of the sealing ring 28. The movable ring 9 can push the sealing ring 28. Under the pushing and squeezing of the movable ring 9, the sealing ring 28 can be deformed to fill the sealing space, thereby ensuring the tightness of the connection.

[0028] The outer surface of the movable ring 9 is fixedly connected with a fixed block 10, and the fixed block 10 is symmetrically arranged outside the movable ring 9. Under the action of the movable ring 9, the fixed block 10 will move, and the interior of the connecting pipe 1 can be clamped through the fixed block 10. At this time, the fixed block 10 can enter the interior of the connecting pipe 1 to limit the position, which can increase the fixing effect on the base 2.

[0029] The outer surface of the movable ring 9 is fixedly connected with a top plate 11, and the top plate 11 is slidably connected to the inside of the fixed ring 2 7. The top plate 11 is a wedge-shaped structure, and the outer surface of the top plate 11 is slidably connected to the inside of the base 2. When the base 2 is connected to the outside, the top plate 11 will be squeezed. At this time, the top plate 11 can push the movable ring 9 to move, thereby realizing the control of the sealing ring 2 8 and the fixed block 10, and ensuring the sealing and connection stability of the base 2.

[0030] Working principle: When installing the base 2, the position of the base 2 can be limited by the limiting ring 3 and the clamping ring 4, which is convenient for the staff to limit the installation of the base 2. The base 2 can be stably connected with the inside of the connecting pipe 1 under the action of the clamping plate 14 and the clamping plate 2 16. The contact position between the base 2 and the connecting pipe 1 can be stably sealed by the action of the sealing ring 1 6 and the sealing ring 2 8. The movable ring 9 can be controlled to move by the action of the top plate 11. The movable ring 9 controls the fixed block 10 to reinforce the base 2 again. After the movable ring 9 controls the sealing ring 2 8 to move, the sealing ring 2 8 can be squeezed to ensure the sealing of the connection.
