Description

Manual-automatic integrated door curtain Technical Field The utility model relates to the field of intelligent household roller shutter curtains, in particular to a manual-automatic integrated door curtain. Background The door curtain plays roles of ventilation, heat insulation, wind prevention and mosquito prevention in daily use, and is widely applied to places such as modern families, businesses, workshops and the like. The long in use has the following problems: the light door curtain is easy to blow by wind, the crashed door is snapped, the magnetic door curtain solves the problem that the door curtain is easy to blow by wind and can be automatically sucked after people get in and out, but the door curtain is pushed by hands or bodies, the surface is easy to dirty, viruses are easy to spread, the magnetic stripe part is easy to absorb dirty things, discolor and clean, the appearance is affected, the bottom of the door curtain is provided with a large gap, dust is easy to blow in by wind, a reptile and a snake are easy to get in a house, the risk is high, the existing door curtain is difficult to meet the decoration style of the existing building, the appearance is not attractive after being assembled, the appearance is uneven, especially for a long time, yellowing, dirty and uneven surface are caused, the good house is particularly not in grade, and the house is inconvenient to store when not used, the common rolling screen door pulls out the spring force, pull out the effort, roll back is the power of coil spring and roll back the curtain cloth, every time open and shut the coil spring and receive a round force, for a long time, elasticity decay inefficacy will cause the roll not to roll back, people can not come in and go out, especially meet fire or special circumstances, escape is difficult, it is inconvenient to open the door, it can stop to pull to any position, pull out effort through frictional force solution, the frictional position life-span is short, unstable and unstable, because people need to business turn over convenience, health, science and technology, select the response automatically-controlled door, but it needs double space just to open, original building and door opening just need to change, cause the waste in space, automatically-controlled door's cost is also high, when the curtain is when opening, there is fly, mosquito entering. In patent cn202310867281.X, when the rope winder is winding the wire, the wire can not be guaranteed to be accurately wound on the rope winder, the condition of messy wires can possibly occur, the wire tensioning device and the coil spring can not solve the problem of matching errors between the rope winder and the reel and the problem of change of the curtain cloth and the wire, when the rope is still motionless, the wire is tensioned to enable the curtain cloth to be tensioned, but when moving, an ineffective stroke still exists, the problem of idle stroke is not solved, the wire is neglected to be loosened, and meanwhile, the wire pulling wheel is increased, so that the abrasion of the wire is increased. The rope winder is connected with the reel, the adjustment of the thickness of the reel, the matching error of the rope winder, the expansion and contraction of the curtain fabric and the elongation coefficient of the pull wire are not available, the tension of the curtain fabric is changed, and the rope winder becomes large under the condition that the width of the door curtain is wider, so that the space waste is caused. After the pull wire is broken and the power is cut off (or the motor fails), the curtain cloth cannot be automatically rolled back. The cord fabric is rolled by the reel, the diameter of the cord fabric is variable, the cord fabric needs to run in the upper and lower tracks (the upper and lower tracks ensure the flatness of the cord fabric), the cord fabric is tensioned, and if the reel cannot move, the cord fabric can have oblique tension when entering the guide rail, and the service life of the cord fabric can be influenced. Disclosure of Invention In order to solve the problems, the utility model provides the manual-automatic door curtain which can be manually or electrically controlled to open and close by sensing, can be manually pushed and pulled after power failure, realizes balance of a rewinding force and a pulling force by utilizing the characteristics of a coil spring, saves labor in pushing and pulling, can be randomly stopped, adopts a rope winder (a big-small head design) synchronous with thickness change of a winding shaft, ensures that the coil spring does not have stress change when the door curtain is opened and closed, always keeps certain elastic force, ensures that the tensioning force of the curtain is uniform and can not be negligibly loosened, ensures the service life of the coil spring, ensures that the door curtain can be automatically rolled back after the wire is broken, does not influence access, ensur
