[0034] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] See also Figure 1-14The invention discloses an embedded wire tube which is convenient for docking, comprising a plurality of plugs 1 which are connected in sequence and are hollow inside. A connecting column 11 is integrally formed at one end of the plug 1. A ring-shaped block 111 with an arc-shaped longitudinal cross section is integrally formed at the outer wall of the end of the connecting column 11 which is far from the plug 1. A chamfer 12 which is inclined inward is provided at the end of the plug 1 which is far from the connecting column 11. A slot 13 whose inner diameter matches the outer diameter of the connecting column 11 is provided near the chamfer 12 inside the plug 1. A slot 13 which is used to accommodate another plug is provided at the side of the slot 13 which is far from the chamfer 12. A card block 111 of a cannula 1 is inserted into a card slot 14, and the cannula 1 at the end is connected to a universal adapter 2 through a connecting column 11. The universal adapter 2 includes a connecting block 21 with an H-shaped cross-section, and two universal connecting blocks 22 are symmetrically rotatably connected at both ends of the connecting block 21. The two universal connecting blocks 22 are respectively rotatably connected to an adapter block 23 and an output block 24. The output block 24 is coaxially slidably connected to a connector 3. The connector 3 includes a limit connector 31 with an external thread on the surface, and the limit connector 31 is threadedly connected to an adapter 4 on the outer side.

[0037] In this embodiment, the connection block 21 is symmetrically provided with four limit rods 211 that are collinear on the same side and opposite to each other on the opposite sides. The limit rods 211 are provided with adapter holes 212 for rotationally connecting with the universal connection block 22. The edges of the connection block 21 are all rounded. The limit rods 211 ensure the relative position with the universal connection block 22 and determine the movement law of the universal connection block 22. The rounded corner treatment reduces the damage of the components caused by stress concentration.

[0038] In this embodiment, the longitudinal cross-section of the universal connecting block 22 is a cross-shaped structure, and four connecting rods 221 are symmetrically distributed around the center of the universal connecting block 22. The universal connecting block 22 is provided with an end hole 222 coaxial with the through hole 213. The setting of the connecting rod 221 on the universal connecting block 22 enables the connecting block 21, the adapter block 23, and the output block 24 to be connected, thereby ensuring the relative rotation of the adapter block 23 and the output block 24 on the connecting block 21.

[0039] In this embodiment, two mutually opposed clamping rods 230 are provided at one horizontal end of the adapter block 23, and both clamping rods 230 are provided with slots 231 for rotationally connecting with two mutually opposed connecting rods 221 on the universal connecting block 22. The setting of the clamping rods 230 limits the position of the universal connecting block 22, and the rotational connection between the slots 231 and the universal connecting block 22 realizes the rotation of the adapter block 23.

[0040] In this embodiment, a limiting column 241 is integrally formed at one end of the output block 24 away from the connecting block 21, and a ring block 242 that is slidably engaged with the connector 3 is provided at one end of the limiting column 241 away from the connecting block 21. The connecting block 21, the universal connecting block 22, the adapter block 23, and the output block 24 are all centrally connected and the inner diameters of the through holes are equal. The setting of the limiting column 241 on the output block 24 ensures the connection between the output block 24 and the cannula 1, and the setting of the integrally formed mechanism reduces the cost and has good practicality. The centrally connected and inner diameters of the through holes are equal, so this setting avoids the difficulty of threading due to different hole sizes.

[0041] In this embodiment, the connector 3 is provided with an annular groove 33 for sliding engagement with the output block 24, and a trumpet-shaped lead groove 32 is symmetrically provided inside the connector 3 near the limit connector 31. The setting of the annular groove 33 improves the firmness of the sliding engagement, and the lead groove 32 facilitates the lead wire to be led out from the inside of the connector 3.

[0042] In this embodiment, a limiting groove 41 for threaded connection with the connector 3 is provided at one end inside the adapter 4, and a fixing groove 42 for slidingly engaging with another insert tube 1 is provided on the side inside the adapter 4 away from the limiting groove 41. The limiting groove 41 ensures the stability of the threaded connection with the limiting connector 31, and the setting of the fixing groove 42 ensures the firmness of the connection with other wire tubes with different apertures.

[0043] Working principle: The embedded wire tube of the utility model is easy to connect. The user can select several insert tubes 1 for sliding connection according to actual conditions when using it. Several insert tubes 1 can form a wire tube of a certain length. The length of the wire tube can be selected according to actual conditions. The insert tube 1 is slidably connected with the universal adapter 2. The universal adapter 2 can change the direction of the output block 24 according to actual needs. The output block 24 is slidably connected with the connector 3, and the connector 3 is threadedly connected with the adapter 4. The model of the adapter 4 can also be replaced to complete the connection of wire tubes of different sizes. This design realizes the connection and installation of wire tubes of any length, any angle and different sizes.
