Abstract
The invention relates to a manual winding structure for a curtain, which comprises a fixed bracket, a bead chain rope, a main sprocket, a main sprocket drive and a pipe column for winding the curtain. The manual winding structure for a curtain is characterized in that a bead chain disc connected with the main sprocket is movably and detachably clamped at the lower part of the fixed bracket; the bead chain rope is wound on the main sprocket of the bead chain disc; the bead chain disc is connected with the pipe column for winding the curtain through a drive mechanism; when the bead chain rope is pulled normally or the bead chain rope is strongly pulled, the bead chain rope cannot fall off; only when the integrated stress of the bead chain disc is downward and reaches a certain value, the bead chain rope falls off; therefore, the manual winding structure for a curtain is stable for use and reasonable in structure, and the ferrule at the free end of the bead chain rope can be prevented from damaging the infant.
Description
Technical field
The present invention relates to a kind of curtain manual coiling device.
Background technology
Manual curtain coiling apparatus, majority are to rely on pelletron, pull with hand bead cord, and the drive curtain is done and rolled or put down action; This kind bead cord stretch out a sagging bead cord, in family uses, can occur twining baby's event, cause and cause injury, disable, even deadly event; Increase a pulley in the free end bottom, this pulley is fixed on the body of wall for this reason, but also because the user does not pack into pulley to bead cord, causes above-mentioned event to still have the possibility of generation, and institute is still dangerous in this way; For this reason through constantly studying with improving, the patent No. is that 200420071930.8 Chinese patent discloses a kind of safety pearl necklace for driving the curtain body folding and unfolding, this pelletron is comprised of several beads and the line that is connected between bead, the two ends of pelletron is incorporated on a connecting seat, form a chain link, form the holding tank that is complementary with bead in the Connection Block, and be extended with splitting groove by holding tank towards the Connection Block end, the width of splitting groove is less than the holding tank internal diameter; Bead on the described pelletron termination is embedded in the holding tank; Adopt such structure, when chain link is subject to certain External Force Acting, but it is embedded at the termination bead trip-free in the Connection Block, namely utilize connectivity structure design and the splitting groove automatic tensioning receipts principle of holding tank and splitting groove to realize, thereby the oneself who reaches chain link unties, avoid its cover to be buckled in the people and to cause unnecessary accident, but the defective of this structure is possible at normal pulling chain rope or stressedly just may cause automatically untiing of chain link when a little bigger, use unstable, come off frequently and cause certain puzzlement to the user, and unreasonable structure, need further to improve.
Summary of the invention
Technical problem to be solved by this invention is the present situation for prior art, providing a kind of bead cord can not occur and come off when normal pulling bead cord, just can cause bead cord to come off and firmly spur bead cord when meeting accident event, thereby avoid occuring the curtain manual coiling structure of injury accident.
The present invention solves the problems of the technologies described above and the technical scheme that adopts is: a kind of curtain manual coiling structure, comprise fixed support, bead cord, head sprocket and head sprocket drive, be used for the reeling tubing string of curtain, it is characterized in that: the pelletron dish that is connected with head sprocket, the pelletron dish is movably, also releasably to be buckled in support bracket fastened bottom, bead cord is wrapped on the head sprocket on the pelletron dish, and the pelletron dish is connected by the tubing string of transmission mechanism with the coiling curtain.
Preferably, described transmission mechanism includes gear wheel, be installed in the support bracket fastened upper cavity, setting is fixed on central gear in the base and a plurality of pinions on the tooth rest, pinion on the tooth rest both with base in central gear be connected with a joggle, internal gear with gear wheel is connected with a joggle again, and the external gear of gear wheel and pelletron dish are connected with a joggle.
Can certainly adopt other transmission mechanism such as gear train to come transmission, the design of these gear trains is conventional art means very.
As improvement, described pelletron dish comprises left pelletron dish, right pelletron dish, and left pelletron dish and head sprocket are one-body molded, and head sprocket is arranged between left pelletron dish and the right pelletron dish, and the bead on the bead cord and the teeth groove on the head sprocket match.
Improve, the lateral surface of described head sprocket is provided with positioning convex column again, and the positioning through hole on this positioning convex column and the right pelletron dish matches.
Preferably, described left pelletron dish and right pelletron dish equal and opposite in direction, shape is identical, and left pelletron dish and right pelletron dish mesh with the gear wheel bottom simultaneously.
At last, the lateral surface of described left pelletron dish and right pelletron dish is provided with axis, and the fixed support bottom is provided with the elasticity card base accordingly, and elasticity card base opposite face forms involutory axis hole, makes axis can be 360 ° and is flexibly connected and is buckled between the elasticity card base.
Compared with prior art, the invention has the advantages that: pelletron is buckled in support bracket fastened bottom with vitalizing dynamic formula, bead cord is wrapped on the head sprocket on the pelletron dish, when the pulling bead cord, can drive the pelletron dish rotates, normal stressed or exert oneself also can not cause bead cord to come off when large, it is stressed downwards and when reaching certain value only to check and regulate body at pelletron, just can cause bead cord to come off, it is stable that it is used, rational in infrastructure, and avoid free end lasso because of bead cord to cause injury to baby or pet, pelletron dish to be arranged on support bracket fastened bottom also can not affecting whole attractive in appearance; Bead cord is arranged on the head sprocket, be between left pelletron dish and the right pelletron dish, make its more stably with head sprocket on teeth groove carry out cooperating, the moving gear wheel of pelletron dribbling rotates, and the internal gear on the gear wheel drives pinion rotation, and pinion drives central gear and rotates, and then the rotation of drive tubing string makes it carry out the folding and unfolding action, when the user carried out the folding and unfolding curtain in the pulling bead cord, easy and flexible was also laborsaving more, and reasonable integral structure is practical.
