Abstract

The invention relates to the technical field of labor protection and safety, and particularly discloses an adjusting buckle for a connective band of a safety helmet, which comprises a bottom shell anda top shell. The bottom shell is detachably connected to the top shell. An adjusting block is rotatably connected to the bottom shell. A gear and an elastic block are fixedly arranged on the adjusting block. Two ends of the connective band can be sleeved on the gear. The gear can be meshed with racks arranged at two ends of the connective band. A connecting seat is arranged on the top shell. Theconnecting seat is provided with inner clamping teeth which are uniformly distributed in a circumferential direction. The elastic block is provided with clamping jaws which are propped against the inner clamping teeth. The solution, through arrangement of the gear, the clamping jaws and the inner clamping teeth, solves the problem of causing discomfort to workers due to that the position of the adjusting buckle moves toward the ears of a human body and a long free section is exposed out of the connective band in the prior art.

Description

technical field [0001] The invention relates to the technical field of labor protection and safety, in particular to an adjustment buckle for a safety helmet connecting belt. Background technique [0002] Existing safety helmet comprises cap body, connecting band and adjusting buckle, cap body is worn on human head by connecting band, and adjusts the size that connecting band is enclosed in human head by adjusting buckle (connecting band enclosing promptly forms cap hoop) so that the safety helmet can be worn by different human bodies; however, the adjustment method in the prior art is: hold the adjustment buckle with one hand, and pull the connecting belt with the other hand, because the adjustment buckle is fixedly connected to the connecting belt One end, so that the connecting belt can only be tightened or loosened to one side. For people with small heads, after the size of the connecting belt is adjusted, the adjustment buckle is no longer on the back of the human head,...
