Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
As shown in Figure 1 to Figure 3, expansion bolt of the present utility model, including connector 10, sleeve pipe 20 and swollen bolt 30.This connector 10 includes barrel 11 and threaded shank 12, this threaded shank 12 is fixed on one end of barrel 11, and this threaded shank 12 extends along the central axis direction of barrel 11, and the inner side of this barrel 11 is provided with the first female thread 111, and this barrel 11 is provided with the first opening away from one end of threaded shank 12；Sleeve pipe 20 is used for being sleeved on threaded shank 12, and this sleeve pipe 20 is provided with multiple fin 21 away from one end of barrel 11, and multiple fins 21 are along the central shaft circumference array of sleeve pipe 20, and form expansion clearance 22 between adjacent fins 21；Being internally formed of swollen bolt 30 connects chamber 31, the inner side in this connection chamber 31 is provided with the second female thread 312, one end of this is swollen bolt 30 is provided with tapered portion 32, this tapered portion 32 is relatively big away from one end external diameter of swollen bolt 30, less near one end external diameter of swollen bolt 30, and connection chamber 31 is provided with the second opening 311 for inserting threaded shank 12 away from one end of tapered portion 32；Swollen bolt 30 is used for being plugged in inside sleeve pipe 20 and threadeds with threaded shank 12, and this tapered portion 32 is for outwards strutting multiple fin 21 when swollen bolt 30 is tightened with threaded shank 12.
