[0003] Most copper connectors commonly found on the market today are similar in overall structure, consisting of a central tube and connecting nuts at both ends. They are connected to external pipes through these connecting nuts. However, they have some functional shortcomings in actual use and have room for improvement. For example, the current connectors require a special wrench to operate, and it is not easy to tighten them completely by hand. They do not have the function of easy hand-tightening for reinforcement.

[0004] Now, a new type of copper connector is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a copper connector to solve the problem mentioned in the background art that it does not have the function of easy hand-tightening and reinforcement.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a copper connector, comprising a central tube body, a central fixing nut fixedly connected at the middle position of the outer side of the central tube body, anti-detachment rings welded on the left and right sides of the central tube body respectively, connecting nuts sleeved on the outer sides of the central tube body respectively, an internal threaded ring welded on the inner side of the connecting nut, and a rotating component for facilitating the rotation of the nut provided on the outer side of the central tube body.

[0007] The rotating assembly includes two sets of limiting rings, which are respectively sleeved on the outside of the central tube. The limiting rings have a hexagonal groove on the side near the connecting nut and a circular groove on the side near the central fixing nut. The upper and lower ends of the limiting rings are respectively fixedly connected with lugs.

[0008] As a further technical solution of this utility model, the inner diameter of the circular groove is consistent with the outer diameter of the internal threaded ring, and the limiting ring can slide left and right along the outside of the central tube and the internal threaded ring.

[0009] As a further technical solution of this utility model, the shape and size of the inside of the hexagonal groove are adapted to the shape and size of the outside of the connecting nut, and the circular groove and the connecting nut are engaged.

[0010] As a further technical solution of this utility model, the interiors of the hexagonal groove and the circular groove are connected, and the ear pieces are symmetrically distributed about the horizontal center line of the limiting ring.

[0011] As a further technical solution of this utility model, a sealing ring is sleeved on the outside of the anti-detachment ring, a first sealing ring is glued to the outer side of the anti-detachment ring, and a second sealing ring is glued to the inner side of the anti-detachment ring.

[0012] As a further technical solution of this utility model, the first sealing ring, the sealing ring and the second sealing ring are ultrasonically welded, and the sealing ring is elastic.

[0013] As a further technical solution of this utility model, the upper and lower ends of the central fixing nut are respectively fixedly connected with internal threaded tube seats, and the upper and lower ends of the central fixing nut are respectively inserted with external bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the copper connector not only realizes the function of easy hand-tightening and reinforcement, but also realizes the function of increasing sealing performance, and also realizes the function of easy twisting of the tube body;

[0016] (1) By setting a limit ring, hexagonal groove, round groove and lug, when in use, the central pipe body serves as a medium conveying channel, and the connecting nuts at both ends are used to connect with the pipeline. When rotating the connecting nut, the limit ring can be pushed towards the connecting nut, and the connecting nut can be inserted into the hexagonal groove. The installer can use his thumb and forefinger to hold the lug and rotate it. The nut can be tightened without the need for wrenches or other installation tools, making it easier to exert force and realizing the function of easy hand-tightening reinforcement.

[0017] (2) By setting a first sealing ring, a sealing ring and a second sealing ring, when the connecting nut is tightened, the connecting nut and the external pipe will clamp the anti-loosening ring in the middle. The first sealing ring and the second sealing ring are on both sides of the anti-loosening ring, which increases the sealing of the contact surface. The sealing ring fits against the inner wall of the connecting nut. Due to its hollow structure, it will deform towards the central pipe body under internal overpressure, blocking the gap and increasing the sealing, thus realizing the function of increasing the sealing.

[0018] (3) By setting an internal threaded tube seat and external bolts, when it is necessary to rotate the central fixing nut, in the absence of a wrench, the two sets of external bolts are screwed into the internal threaded tube seat and tightened.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figure 1-4 A copper connector includes a central tube body 1, a central fixing nut 2 fixedly connected at the middle position of the outer side of the central tube body 1, anti-detachment rings 9 welded on the left and right sides of the central tube body 1 respectively, connecting nuts 8 sleeved on the outer sides of the central tube body 1 respectively, an internal thread ring 7 welded on the inner side of the connecting nut 8, and a rotating component for facilitating the rotation of the nut provided on the outer side of the central tube body 1.

[0026] Please see Figure 1-4 A copper connector also includes a rotating assembly, which includes two sets of limiting rings 3. The two sets of limiting rings 3 are respectively sleeved on the outside of the central tube 1. The limiting ring 3 has a hexagonal groove 4 on the side near the connecting nut 8 and a circular groove 5 on the side near the central fixing nut 2. The upper and lower ends of the limiting ring 3 are respectively fixedly connected with lugs 6.

[0027] The inner diameter of the circular groove 5 is consistent with the outer diameter of the internal thread ring 7. The limiting ring 3 can slide left and right along the outside of the central tube 1 and the internal thread ring 7. The shape and size of the inside of the hexagonal groove 4 are compatible with the shape and size of the outside of the connecting nut 8. The circular groove 5 and the connecting nut 8 are engaged. The inside of the hexagonal groove 4 and the circular groove 5 are connected. The lugs 6 are symmetrically distributed about the horizontal center line of the limiting ring 3, which makes it convenient to tighten the nut.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the limiting ring 3 is pushed toward the connecting nut 8, and the connecting nut 8 is inserted into the hexagonal groove 4. The installer uses his thumb and forefinger to hold the ear piece 6 and rotate it. The nut can be tightened without the need for wrenches or other installation tools, and it is easier to apply force.

[0029] The anti-detachment ring 9 is fitted with a sealing ring 11 on its outer side, and a first sealing ring 10 is glued to the outer side of the anti-detachment ring 9. A second sealing ring 12 is glued to the inner side of the anti-detachment ring 9. The first sealing ring 10, the sealing ring 11, and the second sealing ring 12 are ultrasonically welded. The sealing ring 11 is elastic, which increases the sealing performance.

[0030] Specifically, such as Figure 2 and Figure 4 As shown, the first sealing ring 10 and the second sealing ring 12 are located on both sides of the anti-loosening ring 9 to increase the sealing of the contact surface. The sealing ring 11 fits against the inner wall of the connecting nut 8. Due to its hollow structure, it will deform towards the central tube 1 under internal overpressure to block the gap and increase the sealing.

[0031] The upper and lower ends of the central fixing nut 2 are respectively fixedly connected with internal threaded tube seats 13. The upper and lower ends of the central fixing nut 2 are respectively inserted with external bolts 14. The external threads of the external bolts 14 and the internal threads of the internal threaded tube seats 13 match. The internal threaded tube seats 13 are symmetrically distributed about the horizontal center line of the central tube body 1, which facilitates the rotation of the tube body.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, screw the two sets of external bolts 14 into the internal threaded pipe seat 13 and tighten them. Then, you can rotate the pipe by holding one external bolt 14 in each hand, which makes it easier to apply force.

[0033] Working Principle: In use, the central pipe body 1 serves as the medium conveying channel, with connecting nuts 8 at both ends for connection to the pipeline. When rotating the connecting nuts 8, the limiting ring 3 is pushed towards them, causing the connecting nuts 8 to engage in the hexagonal groove 4. The installer can then use their thumb and forefinger to grip the lugs 6 and rotate the nut, allowing for tightening without a wrench or other tools, making it easier to apply force. As the connecting nuts 8 are tightened, the connecting nuts 8 and the external pipeline clamp the anti-detachment ring 9 in the middle. The first sealing ring 10 and the second sealing ring 12 are located on either side of the anti-detachment ring 9, increasing the sealing of the contact surface. The sealing ring 11 fits against the inner wall of the connecting nuts 8; due to its hollow structure, it deforms towards the central pipe body 1 under internal overpressure, sealing any gaps and increasing the seal. When it is necessary to rotate the central fixing nut 2, in the absence of a wrench, the two sets of external bolts 14 are screwed into and tightened along the internal threaded pipe seat 13. Then, one external bolt 14 is held in each hand for easy rotation, making it easier to apply force.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
