Description

Technical Field

[0001] This utility model relates to the field of home decoration circuit pipe fittings technology, and in particular to a corrugated pipe conversion connector. Background Technology

[0002] In home electrical wiring installation, two types of conduits are used: smooth conduits and corrugated conduits. Smooth conduits have a wide range of matching fittings, but corrugated conduits have relatively fewer. If smooth conduit fittings are used instead, they are prone to detachment during use. An adapter is needed to connect smooth conduits and corrugated conduits, but existing adapters are not secure, and the corrugated conduit can easily detach from the adapter, affecting the wiring installation. Utility Model Content

[0003] To address the aforementioned problems, this utility model aims to provide a corrugated pipe adapter to solve the issue of an unstable connection between the corrugated pipe and the adapter.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution: a corrugated pipe conversion joint, including a conversion joint body and a fixing cover. One end of the conversion joint body is provided with a corrugated pipe socket for connecting a corrugated pipe, and the other end is provided with a socket for connecting a smooth-walled pipe. A first rib is provided on the inner wall of the corrugated pipe socket. One end of the corrugated pipe is inserted into the corrugated pipe socket, and the first rib is snapped into a groove on the corrugated pipe. A U-shaped groove is opened on the wall of the corrugated pipe socket, and the fixing cover is sleeved on the outside of the corrugated pipe socket.

[0005] The corrugated pipe socket is provided with a limiting step inside, and one end of the corrugated pipe abuts against the limiting step.

[0006] The bottom of the U-shaped groove is flush with the surface of the limiting step.

[0007] The first rib is located at the edge of the middle part of the U-shaped groove.

[0008] The inner wall of the fixed cover is provided with multiple second ribs, which are pressed against the outer wall of the corrugated pipe socket.

[0009] Two U-shaped grooves are symmetrically arranged on the wall of the corrugated pipe socket.

[0010] A connecting sleeve is provided between the socket of the adapter body and the smooth wall tube. One end of the smooth wall tube is inserted into the connecting sleeve for connection, and the connecting sleeve is fitted over the outside of the socket. A partition ring is provided inside the connecting sleeve, and retaining ribs are provided on the inner walls on both sides of the partition ring of the connecting sleeve.

[0011] The socket of the adapter body is connected to the socket of the tee box.

[0012] Compared with the prior art, this utility model has the following advantages: the adapter realizes the connection between the corrugated pipe and the smooth pipe. The corrugated pipe is inserted into the corrugated pipe socket, and the rib on the adapter body is snapped into the groove of the corrugated pipe. The deformation of the socket is restricted by the fixing cover, thus realizing a firm connection between the corrugated pipe and the adapter. It is simple to install and easy to use. The corrugated pipe is not easy to fall off during use, which is beneficial to home decoration circuit construction. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0023] Combined with appendix Figures 1 to 7As shown, this embodiment discloses a corrugated pipe adapter, including an adapter body 2 and a fixing cover 3. One end of the adapter body 1 is provided with a corrugated pipe socket 21 for connecting a corrugated pipe 1, and the other end of the adapter body 1 is provided with a socket 22 for connecting a smooth-walled pipe. A first rib 24 is provided on the inner wall of the corrugated pipe socket 21, and the first rib 24 is located at the edge of the middle part of the U-shaped groove 23. When one end of the corrugated pipe 1 is inserted into the corrugated pipe socket 21, the first rib 24 snaps into the groove on the corrugated pipe 1. Two U-shaped grooves 23 are symmetrically opened on the wall of the corrugated pipe socket 21. The U-shaped grooves 23 ensure that the corrugated pipe 1 has a certain space for expansion and deformation when inserted into the corrugated pipe socket 21. The fixing cover 3 is sleeved on the outside of the corrugated pipe socket 21. The fixing cover 3 is used to limit the deformation of the socket of the body at the position of the U-shaped groove 23 and prevent the corrugated pipe from falling off.

[0024] The corrugated pipe socket 21 is provided with a limiting step 25 inside, and one end of the corrugated pipe 1 abuts against the limiting step 25. The bottom of the U-shaped groove 23 is flush with the surface of the limiting step 25, which is beneficial to manufacturing.

[0025] The inner wall of the fixed cover 3 is provided with multiple second ribs 31. The second ribs 31 are pressed against the outer wall of the corrugated pipe socket 21 to ensure that the fixed cover 3 is firmly connected to the conversion connector body 1.

[0026] A connecting sleeve 4 is provided between the socket of the adapter body 2 and the smooth wall tube 5. One end of the smooth wall tube 5 is inserted into the connecting sleeve 4 for connection. The connecting sleeve 4 is fitted over the outside of the socket 22, and one end of the connecting sleeve 4 abuts against the fixing cover 3. A partition ring 41 is provided inside the connecting sleeve 4, and retaining ribs 42 are provided on the inner walls on both sides of the partition ring 41. The inner diameter of the connecting sleeve 4 on both sides of the partition ring 41 is smaller as it gets closer to the partition ring 41, which is beneficial for the connection between the smooth wall tube 5, the socket 22 and the connecting sleeve 4.

[0027] The socket 22 of the adapter body 1 is connected to the socket of the tee box 6. The adapter can be connected to the socket of a smooth-walled pipe, a regular pipe fitting, or a tee box.

[0028] When connecting the corrugated pipe 1, insert the corrugated pipe 1 into the corrugated pipe socket 21. The end of the corrugated pipe 1 rests against the limiting step 25 set inside. The first protruding rib 24 is fastened into the groove on the corrugated pipe 1. Then, the fixing cover 3 is put on the outside of the corrugated pipe socket 21 to limit the deformation of the socket, thus realizing a firm connection between the corrugated pipe 1 and the adapter. The corrugated pipe 1 is not easy to fall off during use. After that, connect the plug of the adapter to the smooth wall pipe 5 or the three-way junction box 6.

[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
