The invention relates to a telescopic locking mechanism for connecting pipe fittings, which overcomes the shortcoming that in the prior art, the mode utilizing a pawl to clamp the pipe fittings has inconvenient adjustment. The locking mechanism comprises a splicing sleeve and a connecting buckle which are used for connecting an upper pipe and a lower pipe; and the splicing sleeve and the connecting buckle are mutually hinged, one end of the splicing sleeve is fixed with the end part of the upper pipe or the end part of the lower pipe, a notch is arranged on the side wall on which the other end of the splicing pipe is located, a spring is arranged between the connecting buckle and the splicing sleeve, a buckle tongue is arranged in the connecting buckle and stretches into the notch, and the end surface of the buckle tongue orients to the interior of the connecting tube. The connecting buckle and the splicing sleeve form a clip structure, which facilitates the telescoping of adjusted pipe fits and can conveniently separate the locking mechanism, thereby releasing clamp force.
Description
technical field [0001] The invention relates to a locking structure, in particular to a locking mechanism for telescopic connecting pipes. Background technique [0002] Nowadays, many long pipe fittings are connected to each other, which simplifies processing and facilitates transportation. For example, in pipe fittings that need to be changed in length, it is more necessary to connect multiple pipe fittings to each other, and the diameters of the connected pipe fittings are different and there is a difference in wall thickness. , when these pipe fittings are connected, a locking piece must be installed at the connecting part, and the pipe fittings should be fixed through the locking piece. When fitting or adjusting the length of pipe fittings, it can be done quickly. For example, a folding chair can be folded. In order to be able to adjust the height of the folding chair, the legs of the folding chair can generally be stretched, and at this time a locking member will be us...
