[0033] Example 1

[0034] Reference Figure 1 、 Figure 2 、 Figure 4-Figure 8 The utility model provides a hidden connector, including a pre-embedded clip 1 and a pre-embedded telescopic tube 2. The pre-embedded clip 1 is hidden and installed in the fixed object, and the pre-embedded telescopic tube 2 is installed in the movable object. One end of the pre-embedded telescopic tube 2 is telescopic and movable, which can be named the telescopic end. When the movable object is combined with the fixed object, the telescopic end of the pre-embedded telescopic tube 2 is clamped in the pre-embedded clip 1.

[0035] Specifically, the embedded clip 1 is sheet-shaped, and the embedded clip 1 includes a accommodating hole 11, a guide portion 12, a connecting hole 13 and a connecting member 14. The guide portion 12 is located in the accommodating hole 11, and the connecting hole 13 is located on both sides of the accommodating hole 11. The connecting member 14 is passed through the connecting hole 13; the accommodating hole 11 is used to place the telescopic end of the embedded telescopic tube 2; the guide portion 12 is used to support the telescopic end when disassembling the movable object, and to make the telescopic end shrink and hide in the movable object; the connecting hole 13 is used to fix the position of the embedded clip, and the connecting member 14 is passed through the connecting hole 13 and nailed into the fixed object. The connecting member 14 can be a screw or a nail.

[0036] Specifically, the guide portion 12 is provided with a sloped surface 121, the slope of which gradually increases as the distance from the receiving hole 11 increases. The principle of this design is that when the movable object needs to be disassembled, the telescopic end of the embedded telescopic tube 2 is pushed toward the guide portion 12. The telescopic end moves out of the receiving hole 11 along the slope of the sloped surface 121 and gradually retracts within the embedded telescopic tube 2, thereby separating the movable object from the fixed object.

[0037] The embedded telescopic tube 2 includes a telescopic member 21 and a tube seat 22. The telescopic member 21 is installed in the tube seat 22. The telescopic member 21 can be telescopically installed in the accommodating hole 11, and the telescopic member 21 resists the guide portion 12; the telescopic member 21 includes a moving rod 211 and a spring 212. A first mounting groove 221 and a second mounting groove 222 are provided in the tube seat 22. The spring 212 is provided in the first mounting groove 221. One end of the moving rod 211 is stuck in the first mounting groove 221, and the other end of the moving rod 211 is movably provided in the second mounting groove 222; when the moving rod 211 is subjected to external force, the spring 212 is deformed, and the moving rod 211 can be retracted in the tube seat 22; when the moving rod 211 is not subjected to external force, the spring 212 is restored, and the moving rod 211 is exposed from the tube seat 22.

[0038] Alternative solution: The telescopic member 21 can also be a hydraulic telescopic tube, which is filled with liquid and the length is adjusted by controlling the flow and pressure of the liquid; or the telescopic member 21 can be a pneumatic telescopic tube, which is filled with gas and the length is adjusted by controlling the flow and pressure of the gas.

[0039] Specifically, the moving rod 211 includes a first section 2111, a second section 2112 and a third section 2113. The diameter of the second section 2112 is larger than the diameter of the first section 2111, and the diameter of the first section 2111 is larger than the diameter of the third section 2113. The second section 2112 clamps the first mounting groove 221, and the third section 2113 is passed through the spring 212. The second section 2112 is just clamped in the notch of the second mounting groove 222, so that the moving rod 211 will not separate from the tube seat 22.

[0040] Preferably, the moving rod 211 may only include the first section 2111 and the second section 2112 , and the third section 2113 may be omitted, and the end surface of the second section 2112 may be used to resist the spring 212 .

[0041] The outer wall of the tube seat 22 is provided with anti-backoff teeth 223, which are used for fixing the pre-buried telescopic tube 2 and the movable object. The anti-backoff teeth 223 increase the friction force and clamp the pre-buried telescopic tube 2 in the movable object.
