Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe connection technology, specifically a corrugated pipe open-type snap-fit quick-change tee connector. Background Technology
[0002] In fluid transportation and cable protection, corrugated pipes are widely used due to their excellent flexibility, resistance to deformation, and sealing performance. Corrugated pipe fittings, as key components for connecting corrugated pipes to each other or to other pipe fittings, directly affect the stability and reliability of the entire pipeline system.
[0003] Existing bellows fittings mostly employ threaded or flanged structures for diameter-changing connections. Threaded fittings require thread engagement to achieve the connection, necessitating matching different thread specifications when connecting bellows of different diameters. This not only makes installation cumbersome and inefficient but also makes it difficult to guarantee a seal during diameter-changing connections. While flanged fittings offer a more robust connection, their complex structure and higher cost, coupled with the need for numerous tools during installation and disassembly, are time-consuming and labor-intensive, failing to meet the demands for rapid installation and flexible diameter changes. Therefore, there is an urgent need for a bellows fitting that enables rapid diameter-changing connections, is easy to install and disassemble, and provides a reliable seal. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1
[0028] like Figure 1-5As shown, in this embodiment, a corrugated pipe open-type snap-fit quick-change tee includes a connector pipe A1 and a reducing connector pipe B2. One end of the connector pipe A1 is used for fixed connection with the corrugated pipe, and the other end of the connector pipe A1 has several openings 11 extending through its side wall, with snaps 12 disposed within each opening 11. The reducing connector pipe B2 includes a pipe body 21, with a baffle 22 at one end of the pipe body 21. A connecting pipe 23 is located at the lower end of the baffle 22, and several check rings 231 are arranged longitudinally on the outer wall of the connecting pipe 23. Several second openings 211 extend through the upper side wall of the pipe body 21, with snaps 212 disposed within each second opening 211. In this embodiment, the connector pipe A1 and the corrugated pipe are an integral structure connected by heat fusion.
[0029] Furthermore, a limit stop 13 is provided on the inner wall of the connector tube A1 and below the opening 11. The limit stop 13 can limit the insertion depth of the variable diameter connector tube B2 to ensure the accuracy and stability of the connection.
[0030] Furthermore, the distance between the upper surface of the limiting block 13 and the opening of the connector tube A1 is L, and L is equal to the length of the connecting tube 23. This setting ensures that the connecting tube 23 can be accurately inserted into the appropriate position inside the connector tube A1, thus guaranteeing the connection effect.
[0031] A limit stop 2 14 is provided on the inner wall of the connector tube A1 and below the opening 211 to limit the insertion of the tube body 21.
[0032] A sealing ring 221 is provided on the bottom surface of the baffle 22. A groove 222 is formed between the sealing ring 221 and the connecting pipe 23. A U-shaped sealing gasket 3 is provided in the groove 222. The U-shaped sealing gasket 3 can effectively improve the sealing performance at the joint and prevent fluid leakage or cable from being affected by the external environment.
[0033] The bottom outer side of the buckle 12 is provided with a slot 121, which facilitates the operation of the buckle 12 during disassembly, making disassembly more convenient and quick.
[0034] The working principle of the above technical solution is as follows:
[0035] During actual installation, the connecting pipe 23 of the reducing connector pipe B2 is aligned with the opening of the connector pipe A1 and inserted. During insertion, the locking clip 12 will undergo elastic deformation under the action of the check ring 231. When the connecting pipe 23 is inserted to the limit stop 13, the locking clip 12 will lock onto the check ring 231, thus achieving the initial connection between the connector pipe A1 and the reducing connector pipe B2.
[0036] If it is necessary to connect to a corrugated pipe of another diameter, the other corrugated pipe can be connected to the pipe body 21 of the reducing fitting pipe B2 in the same way, that is, the corrugated pipe is inserted into the pipe body 21 with the pipe opening aligned with the pipe body 21, and the buckle 212 engages with the inner wall of the corrugated pipe to achieve a stable connection. Example 2
[0037] like Figure 6-8 As shown, in this embodiment, a sealing ring 221 is provided on the bottom surface of the baffle 22, and a groove 222 is formed between the sealing ring 221 and the connecting pipe 23. A U-shaped sealing gasket 3 is provided in the groove 222. The U-shaped sealing gasket 3 can effectively improve the sealing performance at the joint and prevent fluid leakage or the cable from being affected by the external environment.
[0038] The bottom outer side of the buckle 12 is provided with a slot 121, which facilitates the operation of the buckle 12 during disassembly, making disassembly more convenient and quick.
[0039] The working principle of the above technical solution is as follows: the U-shaped sealing gasket 3 on the bottom surface of the baffle 22 can be squeezed and deformed during the connection process to fill the connection gap and ensure a good sealing effect.
[0040] When disassembly is required, a tool can be inserted into the slot 121 at the bottom of the outer side of the buckle 12 and the buckle 12 can be pressed inward to separate it from the check ring 231. The reducing connector pipe B2 can then be easily pulled out of the connector pipe A1. Similarly, the disassembly of the pipe body 21 and the corrugated pipe can be completed. The operation is simple and convenient.
[0041] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
