Quick Positioning Structure of Safety Roller Shutter Limiter

Abstract

The invention relates to a quick positioning structure of a safety roller blind limiter. The quick positioning structure of the safety roller blind limiter mainly has the effects that a shaft rail limiting group is arranged at one end of a shaft rod of a curtain controller in an assembling mode correspondingly, the shaft rail limiting group comprises a screw member, an elastic member and an innertube with a first tooth part arranged on one end surface of the inner tube are arranged on the inner part of the screw member, the inner tube is limited to the inner part of the screw member by a touch member, then a positioning component, a limiting member and an outer sleeve are arranged on the outer part of the screw member in a threaded mode, a sealing cover is correspondingly arranged at oneend of the outer sleeve, and a second tooth part corresponding to the first tooth part is arranged at the position, corresponding to the first tooth part of the inner tube, of the sealing cover; therefore when a cord fabric pipe fitting is assembled in a sleeving mode, an outer ring gear of the positioning component meshes with a positioning ring to position a cord fabric when the cord fabric is unfolded, when the cord fabric pipe fitting is rotated to a cord fabric folding position, the touch member is released to enable the first tooth part of the inner tube to mesh with the second tooth part to achieve a positioning function, and the assembly function of automatically and quickly positioning without screws is achieved.

Description

technical field [0001] The invention relates to a fast positioning structure of a safety roller shutter limiter, in particular to a safety roller shutter rod structure capable of quickly assembling and positioning the curtain retracting position. Background technique [0002] Generally, when assembling the curtains, the construction personnel must adjust the assembly position of the assembly controller stroke path according to the length of the curtain, such as the improvement of the positioning structure of the curtain rod in Taiwan, China Announcement No. M454156, which includes: a pull cord controller, followed by The end is provided with a positioning screw, and a positioning protrusion is provided at the starting point of the front end of the positioning screw; a first collar, which is a corresponding screw sleeve on the positioning screw, and is provided with a first engaging part and a second engaging part on the periphery The first engaging part corresponds to the po...

Problems solved by technology

[0003] The above-mentioned structure is to use the curtain rod to be placed behind the positioning part, after setting the retracting position of the first collar correspondingly, the curtain rod is disassembled and then the first collar is set corresponding to the screw; after that, the curtain rod is reassembled on the The positioning part, after setting the vertical position of the second collar, disassemble the curtain rod again and set the second collar correspondingly to the screw, and finally, formally assemble the curtain rod, as can be seen from the above assembly process, its Disassembling and assembling is troublesome and wastes man-hours. If it is a large curtain, its assembly requires more than two people, which has the disadvantages of cumbersome assembly, time-consuming and labor-consuming, and a waste of personnel costs.
