Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of window curtains, in particular to a Shangri-La window curtain and a light adjusting method thereof. BACKGROUND

[0002] The Shangri-La window curtain is widely favored by consumers due to its unique design and light adjusting function. It can be rolled up like a roller blind and adjusted like a shutter. Generally, the Shangri-La window curtain has a pair of parallel sheets with multiple blades. When the window curtain is closed, the blades are substantially parallel to the pair of sheets, facilitating rolling up. When the window curtain is opened, the blades are substantially perpendicular to the pair of sheets, facilitating light transmission. However, the Shangri-La window curtain needs to be rotated for half a circle after the sheets are completely rolled out, i.e., after the sheets are rolled out to the limit position, to adjust the blades to the position perpendicular to the sheets to achieve light adjustment. At this time, the sheets are completely unfolded and block the entire window area. Therefore, the Shangri-La window curtain cannot be adjusted when the sheets are not completely rolled out. When the sheets are not completely rolled out, the two parallel sheets are in contact with each other, and the blades in the middle are in a vertical state, which is in a light-blocking state. Therefore, people cannot adjust the light when the Shangri-La window curtain is partially unfolded. This is a problem that needs to be solved to facilitate people to adjust the light at any position of the Shangri-La window curtain without completely blocking the window. In addition, the Shangri-La window curtain needs to be customized according to the height of the window area. For example, if the height of the window area is 1.3 meters, a Shangri-La window curtain with an unfolding length of 1.3 meters needs to be customized. If a Shangri-La window curtain with an unfolding length of 1.5 meters is received, the Shangri-La window curtain must be completely unfolded to 1.5 meters to achieve light adjustment. At this time, the extra 0.2 meters of length is redundant. Since the measurement is not accurate under normal circumstances, this problem needs to be solved by returning or cutting. Consumers may also cut roughly, which increases the poor experience of consumers. Moreover, customization makes it difficult for the Shangri-La window curtain to be mass-produced and sold, making it difficult to be put into large-scale stores and supermarkets. Therefore, this is also a problem that needs to be solved to facilitate installation and use and facilitate mass production and sales in stores and supermarkets. SUMMARY

The first and second features can be in direct contact, or the first and second features can be indirectly contacted through an intermediate medium. Moreover, the first feature "above", "above" and "above" the second feature can be the first feature directly above or obliquely above the second feature, or it can only mean that the horizontal height of the first feature is higher than that of the second feature.

[0039] As Figures 1-4As shown, the present application provides a Shangri-La curtain, comprising a winding drum 1, a lower beam 2, and a curtain body 3 connected with the winding drum 1 at the upper end and connected with the lower beam 2 at the lower end, the curtain body 3 comprising a front piece 3.1, a back piece 3.2, and a plurality of connecting pieces 3.3 connected at equal intervals between the front piece 3.1 and the back piece 3.2, a rotatable winding shaft 4 is arranged in the lower beam 2, the lower end of the curtain body 3 is connected with the winding shaft 4, the winding shaft 4 rotates to wind or unwind the lower end of the curtain body 3 to adjust the length of the curtain body 3 unfolded, the upper end of the front piece 3.1 is connected with the winding drum 1, the lower end of the front piece 3.1 is connected with the winding shaft 4, the upper end of the back piece 3.2 is connected with the winding drum 1, the lower end of the back piece 3.2 is connected with the winding shaft 4, the connection positions of the upper end of the front piece 3.1 and the upper end of the back piece 3.2 with the winding drum 1 do not overlap, after the winding drum 1 is rotated to completely unwind the curtain body 3, a certain angle is further rotated to separate the front piece 3.1 and the back piece 3.2, the connecting pieces 3.3 are vertically connected between the front piece 3.1 and the back piece 3.2 to realize light transmission, wherein, the curtain body 3 is always in a light shielding state before being completely unfolded to the light transmission state, that is, the front piece 3.1 and the back piece 3.2 are attached, the connecting pieces 3.3 are vertically clamped between the front piece 3.1 and the back piece 3.2, and the light shielding rate of the connecting pieces 3.3 is greater than that of the front piece 3.1 and the back piece 3.2.

[0040] The traditional Shangri-La curtain is always completely unfolded to adjust the light shielding and light transmission, because the winding drum needs to completely wind or unwind the curtain body to adjust the separation of the front piece and the back piece, and the connecting piece is adjusted from the vertical state to the horizontal state, which leads to the fact that the Shangri-La curtain is completely unfolded when adjusting the light, and the unfolded length is uniquely determined and cannot be changed. For example, if the unfolded length of the curtain body is 1.5 meters, it cannot be changed, and if it needs to be adjusted to 1.3 meters, the winding drum needs to wind the curtain body, and the unfolded part of the curtain body is always in a light shielding state and cannot transmit light, so it is very inconvenient. The present application adds a winding shaft 4 in the lower beam 2 to wind or unwind the lower end of the curtain body 3, the winding shaft 4 can wind or unwind the curtain body 3 from the lower end of the curtain body 3 by rotating, and the unfolded length of the curtain body 3 can be adjusted. When the Shangri-La curtain is completely unfolded to the light transmission state, the lower end of the curtain body 3 can be adjusted to any position within the length range of the curtain body 3 by rotating the winding shaft 4, for example, the unfolded length of the curtain body 3 is 1.5 meters, the winding shaft 4 can be adjusted to make the unfolded length of the curtain body 3 be 1.3 meters, and it will not affect the light transmission, so that the Shangri-La curtain can realize light adjustment at any position without completely shielding the window, and the length of the curtain can be adjusted arbitrarily, which is suitable for windows of various heights and can realize batch production and sales.
