The invention relates to a window covering.

Background technique

The existing two curtains used on the same window door are driven by two independent transmission mechanisms. During work, two curtains are controlled separately by two independent transmission mechanisms. Such curtains, because two sets of transmission mechanisms are required to drive the two curtains to work, the structure is bloated, and installation and use are inconvenient.

Summary of the invention

SUMMARY OF THE INVENTION An object of the present invention is to provide a curtain omnidirectional transmission mechanism which is simple in structure, compact, and easy to install and use.

The present invention is achieved by the present invention, comprising: a curtain bracket, a curtain reel disposed on the curtain bracket, a power transmission mechanism for driving the curtain reel at one end of the curtain reel, and an elastic slewing mechanism disposed in the curtain reel, a rotary release device, the fixed end of the elastic swing mechanism connected to the fixed end of the spring is connected to the bracket, and the movable end of the elastic swing mechanism connected with the movable end of the magazine is connected with the reel, and the activity of the swing release device Partly connected to the reel, the fixing part is connected with the bracket, and the special part is that there are two sets of the curtain reel, and the power transmission mechanism is driven by the gear box, the bead chain and the bead chain which are connected with the bracket and a main gear disposed in the gear box, a one-way rotating mechanism driven by the main gear, a transmission gear disposed in the gear box that meshes with the main gear, and a driven gear that is coupled to the transmission gear and disposed in the gear box The one-way transmission mechanism driven by the driven gear is configured, and the transmission shafts of the two one-way rotating mechanisms are respectively connected to the two curtain reels, two single The unidirectional rotation direction of the rotating mechanism is opposite. The elastic slewing mechanism is provided with a transmission head connected with the one-way rotation mechanism. The transmission head is composed of a rotating shaft, a sleeve sleeved on the rotating shaft, and is disposed on the rotating shaft and the shaft. The elastic mechanism of the sleeve is formed, and the rotating shaft is connected with the one-way rotating mechanism. Together, the sleeve is connected to the reel. During operation, the bead chain drives the main gear to rotate, the main gear drives the one-way rotating mechanism to rotate, and at the same time, the other one-way rotating mechanism is driven by the transmission gear and the driven gear, and the rotation direction of the bead chain and the driving gear directly drive the single When the rotation direction of the rotating mechanism is the same, the one-way rotating mechanism drives the rotating shaft on the driving head to rotate. At this time, under the action of the rotating shaft, the elastic mechanism is tightened, so that the sleeve sleeved on the rotating shaft also follows Rotating, driving the reel to rotate, the direction of rotation of the driven gear is inconsistent with the direction of rotation of the corresponding one-way rotating mechanism, so that the one-way rotating mechanism can not drive the corresponding reel rotation, and so on, when the bead chain is driven in one direction When the driving gear rotates, only one one-way rotating mechanism drives the corresponding reel to rotate, and the other one-way rotating mechanism cannot drive the corresponding reel to rotate. Thus, by pulling the bead chain in two directions, two The curtains on the reel are fully open. When the curtains need to be rolled up, just pull them through the bead chain in the direction in which the curtains are opened and then release them immediately. The rotary release device will be released, so that the fixed part and the movable part can rotate with each other, and the reel will rotate in the elastic slewing mechanism. Under the action of the elastic force, the rotation of the sleeve on the transmission head is also driven by the rotation of the reel. Under the action of the rotation of the sleeve, the elastic mechanism is loosened, and the sleeve is rotated independently from the rotation shaft, so that the curtain is not unidirectional.

During operation, when the one-way rotating mechanism drives the rotating shaft on the driving head to rotate, the curved dial on the rotating shaft drives the transmission spring to rotate by the pulling bar, because the winding direction of the driving spring ring is the same as the rotating direction of the rotating shaft , and the direction of the winding of the coil and the axis of rotation The rotation direction is opposite, therefore, the transmission spring 圏 is tightened on the transmission sleeve, the positioning spring 圏 is loosened on the resilience adjustment shaft, the positioning spring 圏, the positioning curved dial rotates with the rotation shaft, so that the transmission spring 圏, the transmission sleeve , the sleeve, the rotating shaft drives the reel to open the curtain; when the reel is wound by the elastic slewing mechanism, the reel drives the sleeve to reverse rotation, and the sleeve drives the transmission spring 圏 through the transmission sleeve The other spring of the transmission spring 靠 rests on the positioning curved dial, because the rotation direction of the transmission spring 此时 is the same as the 圏 winding direction of the positioning spring, so that the positioning spring 圏 is tightened on the elastic adjustment shaft , the positioning curved dial can not be rotated, and the positioning curved block blocks the direction opposite to the winding direction of the transmission spring, so that the transmission spring ring is loosened on the transmission sleeve and does not rotate with the transmission sleeve, so that the rotating shaft does not follow The sleeve rotates, so that the reel automatically unwinds the curtain without being restricted by the one-way rotation mechanism.

Here, the one-way rotation mechanism is composed of a fixed shaft fixed to the gear box cover, a transmission shaft that is rotatably coupled to the fixed shaft, a spring ring with a shifting bar, and a ring with a stopper on the inner wall, the ring and the driving gear. Or the driven gears are fixed together, the drive shaft passes through the ring, the drive shaft is connected with the rotating shaft on the transmission head of the elastic slewing mechanism, the spring 圏 is sleeved on the transmission shaft, and the spring 圏 on the main gear and the driven gear is wound.

When the direction of rotation of the gear coincides with the direction of the coil of the coil, the ring passes through the stopper and the spring cymbal. The rotation of the spring 圏 causes the spring 圏 to be tightened on the transmission shaft, and drives the transmission shaft to rotate, so that the rotation shaft on the transmission head of the elastic slewing mechanism connected with the reel drives the reel to rotate, so that the winding The curtains on the reel are open.
