Description

But shutter curtain bottom rail connector link of fast-assembling Technical Field The invention relates to the technical field of curtains, in particular to a quickly-assembled blind bottom rail connecting buckle. Background In the process of folding and laying down the shutter of the existing electric shutter, a motor is operated to enable a transmission shaft to rotate so as to drive a lifting belt and a ladder rope on a transmission box, thereby realizing the lifting and the page turning of the shutter. However, the lifting belt and the ladder rope of the existing electric blind can be fixed on the bottom rail by using the connecting buckle, but the existing connecting buckle needs to be accurately aligned and installed, the adjustment allowance is small, the technical requirements on installation personnel are high, and the disassembly and assembly are inconvenient. Disclosure of Invention The invention aims to solve the problems that the existing connecting buckle needs to be accurately aligned and installed, the adjusting allowance is small, and the mounting and dismounting are inconvenient due to high technical requirements for installers. In order to achieve the aim, the invention provides a quick-assembly blind bottom rail connecting buckle which comprises an upper buckle seat and a lower buckle seat, wherein the upper buckle seat is arranged above the lower buckle seat, the upper buckle seat and the lower buckle seat are cross-shaped under the overlooking angle, a connecting section is arranged between the upper buckle seat and the lower buckle seat, the connecting section, the upper buckle seat and the lower buckle seat are of an integrated structure, ladder rope fixing holes are respectively arranged at two ends of the bottom of the upper buckle seat, through holes are formed in the upper buckle seat, the through holes sequentially penetrate through the upper buckle seat, the connecting section and the lower buckle seat from top to bottom, a pin shaft is arranged on the lower buckle seat, and a lifting belt penetrates through the through holes to be connected to the pin shaft. As a further description of the above technical solution: The two ends of the top of the lower buckling seat are respectively provided with at least one propping part, each propping part comprises a propping rod and a first spring, one end of each first spring is connected with the lower buckling seat, and the other end of each first spring is connected with the corresponding propping rod. As a further description of the above technical solution: The lower buckle seat is provided with a mounting groove, the first spring is positioned in the mounting groove, and the jacking rod is movably connected to the mounting groove. As a further description of the above technical solution: the top of the jacking rod is provided with an inclined plane. As a further description of the above technical solution: The lower buckle seat is provided with a shaft hole, and the pin shaft is positioned in the shaft hole.
