[0003] However, the exposed pipe ends of the pre-embedded pipes are easily damaged by various forces during the main construction and the construction of the second-floor structure, which affects the connection and fixation of the external pipes in the later stage.

[0004] Therefore, in order to solve the above problems, a pre-installed connector for electrical conduit without exposed wiring is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-installed connector for electrical conduit that eliminates the need for exposed wiring, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-installed connector for electrical conduit without exposed wiring, applied to floor slabs, comprising:

[0007] An embedded pipe, the top of which is inserted and connected to the bottom of the floor slab;

[0008] An interlocking assembly is used for the enclosure and external connection of a pre-embedded pipe, wherein the bottom of the interlocking assembly is interlocked to the top of the pre-embedded pipe;

[0009] An extension tube is disposed at the bottom of a pre-embedded tube and is used for the extension protection of cables.

[0010] Preferably, the interleaving component includes:

[0011] A sealing cap, the bottom of which is threadedly connected to the top of the pre-embedded pipe, is used to prevent foreign objects from entering the pre-embedded pipe;

[0012] A rotating part is provided on the top of the sealing cap, and the rotating part is used for manually turning the sealing cap.

[0013] Preferably, the rotating part includes:

[0014] A groove is formed at the top of the sealing cap;

[0015] A throttle handle is disposed on the inner wall of a groove and is used for gripping and turning by hand.

[0016] Preferably, a sealing ring is fitted on the outer side of the sealing cap, the sealing ring being used to prevent liquid from entering the pre-embedded pipe.

[0017] Preferably, the interleaving component further includes:

[0018] A connector tube, the bottom end of which is threadedly inserted into the top of the embedded pipe, is used for external extension of the top of the embedded pipe.

[0019] A flipping part is symmetrically arranged on the side of the connector tube, and the flipping part is used for hand-held rotation of the connector tube.

[0020] Preferably, the flipping part includes rotating bars, and a plurality of rotating bars are symmetrically hinged to the side of the connector tube.

[0021] Preferably, the side of the connector tube is provided with a hidden groove, which is used to hide the rotating bar.

[0022] The technical effects and advantages of this utility model are as follows:

[0023] This invention features a connecting component at the top of the embedded pipe, extending the top of the embedded pipe to facilitate connection between the pipe on the floor slab and the embedded pipe. Compared to the embedded pipe protruding directly from the floor slab and connecting to external pipes, this design achieves connection between the embedded pipe and external pipes without the embedded pipe protruding from the floor slab surface, thus avoiding the situation where the embedded pipe protruding from the floor slab surface is easily damaged by external impact.

The insertion component is used for the enclosure and external connection of the embedded pipe 1. The bottom of the insertion component is inserted and connected to the top of the embedded pipe 1. The extension pipe 5 is set at the bottom of the embedded pipe 1. The extension pipe 5 is used for the extension protection of the cable.

[0034] Specifically, the outer side of the extended tube 5 is glued to the inner wall of the embedded tube 1. The extended tube is made of rubber to prevent the cable from rubbing against the inner wall of the port of the embedded tube 1. The inner wall of the embedded tube 1 is threaded. After the concrete of the floor slab 4 is poured, the part of the embedded tube 1 that is above the ground can be cut off to prevent the embedded tube 1 from protruding from the ground and being damaged in subsequent construction. During the cutting process, the threads of the embedded tube 1 are deburred to avoid affecting the thread engagement of the embedded tube 1. Example

[0035] like Figure 1-3 As shown, the insertion assembly in this embodiment is used for sealing the pre-embedded pipe 1;

[0036] Specifically, the interlocking assembly includes a sealing cap 2 and a rotating part;

[0037] It should be noted that the bottom thread of the sealing cap 2 is threaded through and connected to the top of the pre-embedded pipe 1, and the rotating part is located on the top of the sealing cap 2;

[0038] Specifically, the sealing cap 2 is used to prevent foreign objects from entering the pre-embedded pipe 1, and the rotating part is used for the hand-tightening rotation of the sealing cap 2. The rotating part includes: a groove 201 and a handle 202;

[0039] It should be noted that the groove 201 is formed on the top of the sealing cap 2, and the handle 202 is set on the inner wall of the groove 201. The handle 202 is used for hand-tightening. The sealing cap 2 is fitted with a sealing ring 203 on the outer side. The sealing ring 203 is used to prevent liquid from entering the embedded pipe 1. The handle 202 and the sealing cap 2 are integrally injection molded. The sealing ring 203 is made of rubber. The sealing cap 2 can prevent garbage and dust on the surface of the floor slab 4 from entering and blocking the embedded pipe 1, and protect the pipe thread of the embedded pipe 1. The outer side of the sealing cap 2 is provided with the thread corresponding to the embedded pipe 1. The sealing cap 2 is used to protect the embedded pipe 1 when external pipes are installed. Example

[0040] like Figure 4-5 As shown, the insertion component in this embodiment is used for the external extension of the top end of the pre-embedded pipe 1;

[0041] Specifically, the interlocking assembly also includes: connector tube 3 and a flipping part;

[0042] It should be noted that the bottom end of the connector pipe 3 is threadedly connected to the top of the pre-embedded pipe 1, and the flipping part is symmetrically arranged on the side of the connector pipe 3.

[0043] Specifically, the connector tube 3 is used for the external extension of the top of the pre-embedded tube 1; the flipping part is used for the hand-held rotation of the connector tube 3; the bottom outer side of the connector tube 3 is provided with a thread matching the pre-embedded tube 1; the connector tube 3 is used for the pipeline connection at the top of the floor slab 4, so that the external pipe can be directly sleeved on the top of the connector tube 3 for connection.

[0044] It should be noted that the flipping part includes a rotating bar 301, and multiple rotating bars 301 are symmetrically hinged to the side of the connector tube 3;

[0045] Specifically, a hidden groove 302 is provided on the side of the connector pipe 3. The hidden groove 302 is used to hide the rotating bar 301. After the rotating bar 301 is rotated out of the hidden groove 302, the connector pipe 3 is rotated by holding the rotating bar 301 with both hands. The connector pipe 3 is used for external pipe installation. First, the sealing cap 2 in Embodiment 1 is removed, and then the connector pipe 3 is rotated and installed.

[0046] In practical use, by setting a plug-in component on the top of the pre-embedded pipe 1, the top of the pre-embedded pipe 1 is extended by the plug-in component, which facilitates the connection between the pipe on the top of the floor slab 4 and the pre-embedded pipe 1. Compared with the pre-embedded pipe 1 directly protruding from the floor slab 4 and connecting with the external pipe, the plug-in component of this design achieves the connection between the pre-embedded pipe 1 and the external pipe without the pre-embedded pipe 1 protruding from the surface of the floor slab 4, thus avoiding the situation where the pre-embedded pipe 1 protruding from the surface of the floor slab 4 is easily damaged by external force collision.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
