Description

Technical Field

[0001] This utility model belongs to the field of copper connector design technology, and specifically relates to a copper connector that facilitates tube insertion. Background Technology

[0002] Copper fittings are mainly used to connect pipes, equipment, and electrical cables. They are primarily made of copper and often undergo a tin-plating process. Functionally, they can be categorized into reducers, sleeve fittings, and eccentric reducers, and are widely used across various industries.

[0003] Currently, Chinese patent with publication number CN213268248U and publication date of May 25, 2021 discloses an odor-proof and anti-siphon floor drain, including a drain connector and a floor drain cover. The bottom of the floor drain cover is provided with an odor-proof silicone drain pipe. The floor drain cover is connected to the bottom of the drain connector. The side of the drain connector is provided with an upwardly inclined one-way air return pipe, and a one-way air return valve is provided inside the one-way air return pipe.

[0004] The drain cover is equipped with a threaded silicone sealing ring. When the drain cover is installed on the drain pipe, the threaded silicone sealing ring is used to press against the inner wall of the drain pipe, thereby achieving temperature installation of the drain cover at the upper end of the drain pipe. However, different drain pipe specifications have different inner diameters. In this case, it is necessary to replace the threaded silicone sealing ring to adapt to drain pipes with different inner diameters, which will ultimately cause inconvenience in the connection between the joint and the drain pipe. Utility Model Content

[0005] The purpose of this invention is to provide a copper connector that is easy to insert, which is beneficial for connecting drain pipes of different inner diameters.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a copper connector for easy insertion of a pipe, comprising a connector body and an end cap disposed on the connector body for covering the upper end of a drain pipe. An externally threaded insert is disposed at the end of the connector body and below the end cap for insertion into the drain pipe. Sliding grooves are provided on both sides of the externally threaded insert. An adjusting ring is fitted onto the externally threaded insert. A slider embedded in the sliding groove is disposed on the inner wall of the adjusting ring. Multiple arc-shaped elastic retaining plates are disposed around the adjusting ring and their lower ends are fixedly connected to the adjusting ring. A first internally threaded sleeve is threadedly connected to the lower end of the externally threaded insert and abuts against the adjusting ring. A rubber sleeve for abutting against the inner wall of drain pipes with different inner diameters is fitted onto the middle of the elastic retaining plate.

[0007] A further feature of this invention is that the first internal threaded sleeve has a first anti-slip stripe on its circumference.

[0008] A further feature of this invention is that a stepped surface is formed between the connector body and the external threaded tube for the end cap to abut against, an external threaded surface is provided on the peripheral outer wall of the connector body near the end of the external threaded tube, and a second internal threaded sleeve is provided at the center of the end cap, which is threaded onto the external threaded surface.

[0009] A further feature of this invention is that a second anti-slip stripe is provided on the periphery of the end cap.

[0010] A further feature of this invention is that a flexible nylon sleeve is provided on the lower side of the first internal threaded sleeve, and the lower end of the flexible nylon sleeve is open and both sides are provided with magnetic strips for mutual attraction.

[0011] A further feature of this invention is that: the upper end of the connector body is provided with a tube head, the end of the tube head is provided with a tube end with a gradually decreasing diameter, and the periphery of the tube end is provided with a plurality of annular grooves for clamping and locking.

[0012] A further feature of this invention is that multiple annular grooves are formed on the periphery of the insertion head, and rubber sealing rings are embedded in the annular grooves.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. When it is necessary to insert the external threaded tube into the drain pipe, according to the inner diameter of the drain pipe, the first internal threaded sleeve is rotated to push the adjusting ring to move up and down along the slide groove. At this time, the arc-shaped elastic plate will bend to different degrees due to the movement of the adjusting ring. When the elastic plate bends more, it can correspond to the inner diameter of the drain pipe. When the elastic plate bends less, it can correspond to the inner diameter of the drain pipe. After the bending degree of the elastic plate is adjusted, the external threaded tube can be inserted into the drain pipe. At this time, the elastic plate can be pressed against the inner wall of the drain pipe by the rubber sleeve. Since the rubber sleeve itself has a large coefficient of friction, a large frictional force is generated between it and the inner wall of the drain pipe, which can finally achieve the connection of drain pipes with different inner diameters.

[0015] 2. The first anti-slip stripe on the circumference of the first internal threaded sleeve can play an anti-slip role, which is conducive to the stable rotation of the first internal threaded sleeve;

[0016] 3. When it is necessary to disassemble the connector body on the drain pipe, it is difficult to pull out the external threaded tube because the elastic plate is pressed against the inner wall of the drain pipe. At this time, by rotating the end cap, the end cap is moved away from the elastic plate. Then the elastic plate will elastically recover, so that the pressing state between the drain pipe and the elastic plate is released, and finally the external threaded tube in the drain pipe can be easily pulled out.

[0017] 4. The second anti-slip stripe on the periphery of the end cap can play an anti-slip role, which is conducive to the stable rotation of the end cap;

[0018] 5. When water flows out from the external threaded tube, the water flow can open the two magnetic strips. When the water flow stops, the two magnetic strips can be attracted together by magnetic attraction, thereby closing the lower opening of the flexible nylon sleeve, and finally achieving the functions of deodorization and insect prevention.

[0019] 6. When external pipelines are required on the connector body, the insertion end of the insertion head can be fitted with external pipelines of different inner diameters, and the annular groove can be used to easily tighten the clamps on the external pipelines.

[0020] 7. When the connector is directly inserted into the external pipeline, the rubber sealing ring around the connector can be used to press against the inner wall of the external pipeline, thereby improving the sealing performance of the external pipeline when it is inserted into the connector.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] A copper connector for easy tube insertion, see reference. Figure 1 The copper connector for easy pipe insertion includes a connector body 1 and an end cap 2 disposed on the connector body 1 and used to cover the upper end of the drain pipe. The connector body 1 is made of copper material and has good corrosion resistance. At the same time, the upper end of the connector body 1 is integrally provided with a pipe insertion head 12, and the end of the pipe insertion head 12 is integrally provided with a pipe insertion end 121 with a gradually decreasing pipe diameter. The periphery of the pipe insertion end 121 is provided with multiple annular grooves 1211 for clamping and locking, and the periphery of the pipe insertion head 12 is also provided with multiple annular grooves 122, and a rubber sealing ring 123 is embedded in the annular grooves 122.

[0028] Reference Figure 1 , Figure 2 , Figure 3 The end of the connector body 1 and the lower side of the end cap 2 are integrally provided with an external threaded tube 3 for insertion into the drain pipe. A stepped surface is formed between the connector body 1 and the external threaded tube 3 for the end cap 2 to abut against. An external threaded surface 11 is provided on the outer peripheral wall of the connector body 1 near the external threaded tube 3. At the same time, a second internal threaded sleeve 21 is integrally provided at the center of the end cap 2, which is threaded to the external threaded surface 11. A second anti-slip stripe 22 is provided on the periphery of the end cap 2.

[0029] Reference Figure 1 , Figure 2 , Figure 3 The external threaded insertion tube 3 has grooves 31 on both sides, and an adjusting ring 4 is fitted on the external threaded insertion tube 3. The inner wall of the adjusting ring 4 has a slider 41 embedded in the groove 31. Multiple elastic plates 42 are provided around the adjusting ring 4. The multiple elastic plates 42 are evenly spaced along the circumference of the adjusting ring 4. The elastic plates 42 are made of spring steel. The elastic plates 42 are arc-shaped and their lower ends are welded and fixed to the adjusting ring 4. A rubber sleeve 421 for pressing against the inner wall of drain pipes with different inner diameters is fitted and bonded to the middle of the elastic plates 42. At the same time, the lower end of the external threaded insertion tube 3 is threadedly connected to a first internal threaded sleeve 5 that presses against the adjusting ring 4. The circumference of the first internal threaded sleeve 5 has a first anti-slip stripe 51. A flexible nylon sleeve 6 is bonded and fixed to the lower side of the first internal threaded sleeve 5. The lower end of the flexible nylon sleeve 6 is open and both sides are bonded and fixed with magnetic strips 61 for mutual attraction.

[0030] Principle: When the external threaded tube 3 needs to be inserted into the drain pipe, the first internal threaded sleeve 5 is rotated according to the inner diameter of the drain pipe, thereby pushing the adjusting ring 4 to move up and down along the slide groove 31. At this time, the arc-shaped elastic plate 42 can bend to different degrees due to the movement of the adjusting ring 4. When the elastic plate 42 bends more, it can correspond to the inner diameter of the drain pipe with a larger size, and when the elastic plate 42 bends less, it can correspond to the inner diameter of the drain pipe with a smaller size. After the bending degree of the elastic plate 42 is adjusted, the external threaded tube 3 can be inserted into the drain pipe. At this time, the elastic plate 42 can be pressed against the inner wall of the drain pipe by the rubber sleeve 421. Since the rubber sleeve 421 itself has a large coefficient of friction, a large frictional force is generated between it and the inner wall of the drain pipe, and finally, the drain pipes with different inner diameters can be connected.

[0031] When it is necessary to disassemble the connector body 1 on the drain pipe, it is difficult to pull out the external threaded tube 3 because the elastic clamp 42 is pressed against the inner wall of the drain pipe. At this time, by rotating the end cap 2, the end cap 2 is moved away from the elastic clamp 42. Then the elastic clamp 42 can elastically recover, so that the pressing state between the drain pipe and the elastic clamp 42 is released, and finally the external threaded tube 3 in the drain pipe can be easily pulled out.
