Description

Technical Field

[0001] This utility model relates to the field of plumbing fittings technology, specifically a connector for plumbing fittings. Background Technology

[0002] Pipe fittings are a general term for components in a piping system that serve functions such as connection, control, direction change, flow diversion, sealing, and support. Based on different manufacturing processes, they are divided into four main categories: butt-welded pipe fittings, socket-welded and threaded pipe fittings, and flanged pipe fittings. Plumbing fittings are pipes used to transport hot or cold water and are among the most common pipe fittings in daily life. They are typically used in plumbing systems in homes, commercial buildings, and industrial buildings. When laying and using plumbing pipes, connectors are needed to connect the joints between two plumbing fittings.

[0003] Traditional plumbing fittings typically use threaded connections for installation. The main installation steps are: first, thread the fitting onto the pipe end of the plumbing fitting; then, thread the pipe end of another plumbing fitting onto the other end of the fitting. During installation, the second plumbing fitting usually needs to be rotated. However, during plumbing fitting maintenance, most plumbing fittings are laid out in a fixed position, making it difficult to rotate them and inconvenient for workers to connect two fittings together.

[0004] To address the aforementioned problems, we propose a connector for plumbing pipes. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a connector for plumbing pipe fittings. When connecting plumbing pipe fittings, only two connector heads need to be twisted, without rotating the plumbing pipe fittings. This utility model is suitable for maintenance and replacement work when plumbing pipe fittings are in a fixed position. Finally, the connector base and connector cover plate are sealed together to connect and fix the joint of two plumbing pipe fittings, thereby enhancing the convenience of maintenance and replacement of plumbing pipe fitting joints.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A connector for plumbing pipes includes a connecting base cylinder and a connecting cover plate fitted to the upper surface of the connecting base cylinder. Limiting components are provided at both ends of the inner cavities of the connecting base cylinder and the connecting cover plate. Each limiting component includes a first limiting groove and a second limiting groove.

Two sets of connectors are provided, each snapped into the middle of the inner side of one of the two sets of limiting components.

[0008] Preferably, the fixing component includes a first connecting plate and a second connecting plate. The first connecting plate is installed on the outer end of the connecting bottom cylinder, and the second connecting plate is installed on the outer end of the connecting cover plate. When the connecting cover plate and the connecting bottom cylinder are in a spliced ​​state, the first connecting plate and the second connecting plate are fitted together and locked by fixing bolts.

[0009] Preferably, the splicing surface of the connecting bottom cylinder and the connecting cover plate is provided with a sealing component. The sealing component includes a first sealing groove and a second sealing groove. The first sealing groove is opened on both sides of the upper end of the connecting bottom cylinder, and an elastic sealing strip is installed in the first sealing groove. The second sealing groove is opened on both sides of the bottom end of the connecting cover plate.

[0010] Preferably, both the first limiting groove and the second limiting groove are configured as semi-circular structures, and both are provided with sealing gaskets on the splicing surfaces, so that the first limiting groove and the second limiting groove form a sealed annular structure after splicing.

[0011] Preferably, the connecting bottom cylinder and the connecting cover plate are movably connected by two sets of hinges.

[0019] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0020] Example: Refer to Figure 1 - Figure 3 As shown, a plumbing connector of this embodiment includes a connecting base cylinder 1 and a connecting cover plate 2 that is fitted and installed on the upper surface of the connecting base cylinder 1. Limiting components are provided at both ends of the inner cavity of the connecting base cylinder 1 and the connecting cover plate 2. The limiting components include a first limiting groove 11 and a second limiting groove 21. The first limiting groove 11 is fixedly installed on both sides of the inner cavity of the connecting base cylinder 1, and the second limiting groove 21 is fixedly installed on both sides of the inner cavity of the connecting cover plate 2. Connecting head 3 is provided in two sets, which are respectively snapped into the middle of the inner side of the two sets of limiting components.

[0021] During use, the two connectors 3 are threaded to the joints of the two water pipe fittings respectively, and then the connectors 3 are snapped into the first limiting groove 11 for sealing connection. Then, by covering the connecting cover plate 2, the second limiting groove 21 is sealed and spliced ​​with the first limiting groove 11, so that the two connectors 3 are in a connected state.

[0022] The fixing component includes a first connecting plate 13 and a second connecting plate 23. The first connecting plate 13 is installed on the outer end of the connecting bottom cylinder 1, and the second connecting plate 23 is installed on the outer end of the connecting cover plate 2. When the connecting cover plate 2 and the connecting bottom cylinder 1 are in the splicing state, the first connecting plate 13 and the second connecting plate 23 are fitted together and locked by fixing bolts, thereby enhancing the stability of the sealed splicing between the connecting bottom cylinder 1 and the connecting cover plate 2.

[0023] A sealing assembly is provided at the splicing surface of the connecting bottom cylinder 1 and the connecting cover plate 2. The sealing assembly includes a first sealing groove 12 and a second sealing groove 22. The first sealing groove 12 is opened on both sides of the upper end of the connecting bottom cylinder 1, and an elastic sealing strip 4 is installed in the first sealing groove 12. The second sealing groove 22 is opened on both sides of the lower end of the connecting cover plate 2. The elastic sealing strip 4 mainly plays a role in sealing the connection gap between the connecting bottom cylinder 1 and the connecting cover plate 2 to prevent leakage.

[0024] In some examples, both the first limiting groove 11 and the second limiting groove 21 are set as semi-circular structures, and sealing gaskets are provided on the splicing surfaces. After the first limiting groove 11 and the second limiting groove 21 are spliced ​​together, they form a sealing ring structure, which enhances the sealing performance and prevents leakage.

[0025] In some examples, the connecting bottom cylinder 1 and the connecting cover plate 2 are movably connected by two sets of hinges 5, which makes it convenient for workers to open or close the connecting cover plate 2.

[0026] In some examples, the end of connector 3 is provided with an external thread structure to facilitate the connection and fixation of connector 3 with the plumbing fitting.

[0027] The working principle of this utility model is as follows:

[0028] When connecting two plumbing fittings, the worker first needs to install connector 3 on the ends of both fittings. Then, connector 3 is inserted into the first limiting groove 11 on both sides. At this time, the connecting cover plate 2 is placed on top, so that the second limiting groove 21 and the first limiting groove 11 are sealed and spliced ​​to form a sealing ring structure, thereby sealing and locking the connector 3, enhancing the stability of the connector 3 installation, and making the two plumbing fittings connected. Finally, the first connecting plate 13 and the second connecting plate 23 are fixedly connected by fixing bolts, thereby realizing the connection between the two plumbing fittings.

[0029] With the above structure, when connecting water pipe fittings, only the two connectors 3 need to be turned, without rotating the water pipe fittings. This makes it suitable for maintenance and replacement work when the water pipe fittings are in a fixed position. Finally, the connection base cylinder 1 and the connection cover plate 2 are sealed and spliced ​​together to connect and fix the joint of the two water pipe fittings, thereby enhancing the convenience of maintenance and replacement of the water pipe fitting joint.
