Description

Technical Field

[0001] The utility model relates to the technical field of water pipe joints, in particular to a rotatable joint. Background Technique

[0002] A water pipe joint is a device for connecting two or more water pipes. A water pipe joint is a component used to connect water pipes and is extremely common in daily life and in construction work. Water pipe joints can be classified according to their usage methods into: externally threaded end-connected water pipe joints, ferrule-type water pipe joints, and self-fixing water pipe joints. Water pipe joints are usually made of different materials, such as copper, steel, plastic, etc., and have characteristics such as corrosion resistance and high pressure resistance. Common types of water pipe joints include threaded joints, clamp joints, flange joints, etc. These joints can all provide reliable connection and sealing to ensure unobstructed water flow. Currently, in the market, when using a water pipe joint, since the joint cannot rotate, the water pipe is distorted, rotated, deformed, etc. during the installation process, and manual correction of the water pipe is required before it can be used, making the installation process extremely complex, cumbersome, and very inconvenient.

[0003] A water pipe joint disclosed in the Chinese Utility Model Patent Application Publication Specification CN218895109U, although this device makes the applicable range of the water pipe joint of the present application larger by means of a connecting disk that is detachably connected to each other and a connecting pipe including pipe bodies of different diameters, and the pipe bodies of different diameters can be connected to water pipes of different specifications, the existing device does not solve the problem that when using a water pipe joint, since the joint cannot rotate, the water pipe is distorted, rotated, and deformed, etc. during the installation process, and manual correction of the water pipe is required before it can be used, making the installation process extremely complex, cumbersome, and very inconvenient. Therefore, we propose a new device to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a rotatable joint, which solves the problem that the existing water pipe joint is prone to cause the water pipe to be distorted and deformed during installation, and manual correction of the water pipe is required, resulting in a complex and cumbersome installation process.

[0005] To achieve the above object, the utility model is realized through the following technical solutions: A rotatable joint includes a sealing member, a sealing ring is sleeved on the surface of the sealing member, a clamping groove is provided on the outer surface of the sealing member for clamping the sealing ring, a joint is sleeved on the surface of the sealing member, a nut is installed on the surface of the joint, the joint can rotate inside the nut, a sealing groove adapted to the sealing ring is provided inside the joint, and the sealing groove and the sealing ring are in a dynamic sealing state.

[0006] Optionally, a stepped groove is provided inside the nut, one end of the stepped groove is adapted to the joint, and the other end of the stepped groove is adapted to the sealing member.

[0007] Optionally, the number of sealing grooves provided inside the joint is two, and the size of the sealing grooves is slightly larger than that of the sealing rings.

[0008] Optionally, anti-slip patterns are sequentially provided on the surface of the nut from top to bottom. The number of the anti-slip patterns is two, and a groove is provided between the anti-slip patterns.

[0009] Optionally, the number of the sealing rings is two. A circular ring is provided on the surface of the joint, and the joint is a riveted joint.

[0010] Optionally, protruding rings are sequentially provided on the surface of the joint from top to bottom. The number of the protruding rings is two. A connecting ring is provided at the lower part of the joint where the protruding rings are located, and the volume of the connecting ring is larger than that of the protruding rings.

[0011] In summary, the technical effects and advantages of the present utility model are as follows:

[0012] 1. The structure of the present utility model is reasonable. During use, the sealing ring is installed on the surface of the seal, and then the seal is inserted into the inside of the joint, so that the outer wall of the sealing ring contacts the inner wall of the sealing groove of the joint, thereby playing a role in waterproof sealing, solving the problem that water leakage easily occurs when the water pipe joint is connected to the water pipe, achieving the effect of enhancing the waterproof sealing of the water pipe joint through the sealing ring and the seal, greatly reducing the situation of water leakage when the water pipe joint is in use. By inserting the assembled seal, sealing ring and joint into the inside of the nut, the upper part of the stepped groove contacts the joint, and the lower part of the stepped groove contacts the seal. Then, by tightening the external bolt through the threaded hole, the seal, sealing ring and joint can be connected to the nut. The joint can rotate independently in the nut, solving the problem that in the prior art, when the water pipe joint is in use, due to the inability to rotate the joint, the water pipe is distorted, rotated and deformed during the installation process, and manual correction of the water pipe is required to be used, making the installation process extremely complex and cumbersome and very inconvenient. It achieves the effect that by rotating the nut of the rotatable joint, the nut and the seal can rotate freely around the central axis relative to the joint by 360 degrees during the tightening process, so that the riveted water pipe will not be distorted, rotated and deformed, etc., greatly enhancing the installation efficiency of the operator. Through the anti-slip patterns provided on the surface of the nut, the problem that it is easy to be too slippery during the installation of the water pipe joint assembly and the docking of the water pipe joint and the water pipe due to water on the surfaces of the water pipe and the water pipe joint, making it inconvenient to install, is solved. It achieves the effect that the friction between the operator and the water pipe joint can be enhanced through the anti-slip patterns on the surface of the nut, thereby avoiding slipping, and greatly enhancing the friction between the operator and the water pipe joint.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment: Refer to Figures 1-4 A rotatable connector shown, including a seal 1, a sealing ring 2 is sleeved on the surface of the seal 1, a clamping groove is provided on the outer surface of the seal 1 for clamping the sealing ring 2, a connector 3 is sleeved on the surface of the seal 1, a nut 4 is installed on the surface of the connector 3, the connector 3 can rotate inside the nut 4, a sealing groove adapted to the sealing ring 2 is provided inside the connector 3, and the sealing groove and the sealing ring 2 are in a dynamic sealing state.

[0020] As a preferred implementation manner in this embodiment, as shown in Figures 1-3As shown in the figure, it includes a seal 1. A sealing ring 2 is sleeved on the surface of the seal 1. A clamping groove is provided on the outer surface of the seal 1 to clamp the sealing ring 2. A joint 3 is sleeved on the surface of the seal 1. A nut 4 is installed on the surface of the joint 3. The joint 3 can rotate inside the nut 4. A sealing groove adapted to the sealing ring 2 is provided inside the joint 3, and the sealing groove and the sealing ring 2 are in a dynamic sealing state. A stepped groove 6 is formed inside the nut 4. One end of the stepped groove 6 is adapted to the joint 3, and the other end of the stepped groove 6 is adapted to the seal 1. The number of sealing grooves provided inside the joint 3 is two. The size of the sealing groove is slightly larger than that of the sealing ring 2. Two anti-slip lines are sequentially provided on the surface of the nut 4 from top to bottom. A groove is provided between the two anti-slip lines. The number of the sealing rings 2 is two. A circular ring is provided on the surface of the joint 3. The joint 3 is a riveted joint. Protruding rings are sequentially formed on the surface of the joint 3 from top to bottom. The number of the protruding rings is two. A connecting ring is provided below the protruding rings of the joint 3. The volume of the connecting ring is larger than that of the protruding rings, presenting a pagoda shape, which can clamp the butt joint pipeline to prevent it from falling off. During use, by installing the sealing ring 2 on the surface of the seal 1 and then inserting the seal 1 into the joint 3, the outer wall of the sealing ring 2 contacts the inner wall of the sealing groove of the joint 3, thus playing a role in waterproof sealing, solving the problem that water leakage is likely to occur when the water pipe joint is connected to the water pipe and used, achieving the effect of enhancing the waterproof sealing of the water pipe joint through the sealing ring 2 and the seal 1, greatly reducing the situation of water leakage when the water pipe joint is used. By inserting the assembled seal 1, sealing ring 2 and joint 3 into the nut, the upper part of the stepped groove 6 contacts the joint 3, and the lower part of the stepped groove 6 contacts the seal 1. Then, by tightening the external bolt through the threaded hole 5, the seal 1, sealing ring 2 and joint 3 can be connected to the nut 4. The joint 3 can rotate independently in the nut 4, solving the problem that when the existing water pipe joint is used, due to the inability of the joint to rotate, the water pipe is distorted, rotated and deformed during the installation process, and manual correction of the water pipe is required to use it, making the installation process extremely complicated and cumbersome and very inconvenient. During the tightening process, the nut 4 and the seal 1 can rotate freely around the central axis relative to the joint 3, so that the riveted water pipe will not be distorted, rotated and deformed, etc., greatly enhancing the installation efficiency of the operator. Through the anti-slip lines provided on the surface of the nut 4, the problem that it is easy to be too slippery during the installation of the water pipe joint assembly and the docking of the water pipe joint and the water pipe due to water on the surfaces of the water pipe and the water pipe joint, making it inconvenient to install, is solved. The effect of enhancing the friction between the operator and the water pipe joint through the anti-slip lines on the surface of the nut 4 to avoid slipping is achieved, greatly enhancing the friction between the operator and the water pipe joint. It should be noted that the dynamic sealing state between the sealing groove and the sealing ring 2 refers to the sealing between relatively moving parts in a machine (or structure). Dynamic seals are divided into two categories: reciprocating dynamic seals and rotary dynamic seals.Reciprocating dynamic seals include molded packing seals, stuffing box seals, and packing ring seals. Rotary dynamic seals include: contact dynamic seals where the moving part directly contacts the stationary part; non-contact dynamic seals where the two do not directly contact; and semi-fluid dynamic seals that achieve sealing by utilizing the special properties of the fluid added to the sealing gap. Magnetic fluid seals are semi-fluid dynamic seals. Some machines and equipment must be absolutely sealed, while some allow a small amount of leakage. Therefore, the structural type of the seal should be selected or designed according to the operating conditions such as the nature, temperature, pressure, and relative speed of the working medium, as well as the requirements for sealing performance.

[0021] The working principle of this utility model:

[0022] During use, the waterproof sealing effect of the water pipe joint is enhanced through the sealing ring 2 and the seal 1. By inserting the assembled seal 1, sealing ring 2, and joint 3 into the nut, the upper part of the stepped groove 6 contacts the joint 3, and the lower part of the stepped groove 6 contacts the seal 1. Then, by tightening the external bolt through the threaded hole 5, the seal 1, sealing ring 2, and joint 3 can be connected to the nut 4. The joint 3 can rotate independently in the nut 4, and the thread is tightened to connect the joint. During the tightening process, the nut 4 and the seal 1 can rotate freely around the central axis relative to the joint 3 by 360 degrees, so that the riveted water pipe will not have problems such as twisting, rotation, and deformation. Through the anti-slip pattern provided on the surface of the nut 4, it solves the problem that when installing the water pipe joint assembly and when the water pipe joint is docked with the water pipe, it is easy to be too slippery during installation due to the water on the surfaces of the water pipe and the water pipe joint, making it inconvenient to install.

[0023] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
