Abstract
The utility model relates to a two-wheel curtain opening device which is composed of pulleys, a pull strap, a hanging ring, a suspension rail and a hanging hook. The pull strap is sheathed on one pulley at one side, and both sides of the pull strap are connected with the other pulley at the other side; one side of the pull strap is overlapped on the pulley, and the other side is wound on the pulley for a circle from bottom to top; a curtain clamp penetrates on the suspension rail; the pull strap is connected with the curtain clamp; the pulley is composed of a pulley body and a pulley cap. The pulley wheel body is provided with an anti-slide slot, and the pulley wheel cap is provided with a convex part. The utility model makes use of the specially designed pulley, which reduces the friction between the rotary pulley and a support object and other adverse influences, and the structure connected with the pull strap adds adhesive force. The utility model has the advantages of labor saving, low cost and high durability, and overcomes the hidden trouble of the falling of the pull strap; the curtain with different use widths can be flexibly selected.
Description
The utility model relates to a kind of device that is used to hang curtain, folding curtain.
In the prior art, curtain open/close device generally has 3 pulleys, is fixed on the supporter both sides, and a side is fixed one, and opposite side is coaxial fixes two; Drawstring is enclosed within on the single pulley, and both sides ride over respectively on two pulleys of opposite side; Two-wheeled switched in opposite during use, reach each other and supporter between friction bigger, use comparatively effort, drawstring also comes off from pulley easily, so product technology is complicated, and simultaneously commercially available curtain open/close device uses width adjusting loaded down with trivial details, inconvenience is installed, and cost is than higher.
The purpose of this utility model is: provide a kind of structure more simple, two-wheel curtain open/close device especially easily is installed, use specially designed pulley, reduced when pulley rotates and frictional force and other adverse effect between the supporter, and the structure that is connected with drawstring has increased drawstring adhesive force, use laborsaving, overcome the drawstring hidden danger that comes off, select the different width that use of curtain flexibly, cost is low, durable, and is easy for consumers to accept.
The utility model is to constitute like this: by pulley (1), drawstring (3), hanging ring (5) and outstanding rail (4), hook (2) constitutes, on the wheel post (8) of pulley (1) anti-skidding muscle is arranged, the side of pulley (1) has a projection (10), drawstring (3) is enclosed within on the pulley of a side (1), drawstring (3) the both sides pulley of opposite side (1) of ining succession, drawstring (3) rides on this pulley (1) on one side, drawstring (3) another side is from the bottom up around this pulley one circle, adjustable ring (6) is enclosed within on one side, and drawstring (3) upward forms kink (11), kink (11) is enclosed within on the hanging ring (5), and drawstring (3) is entangled in anti-knocking over (7), link to each other with the hanging ring (5) on the hook (2).
The utility model with obviously simplified existing curtain open/close mechanism, only with two same install, through specially designed pulley, reduced the friction between pulley and the supporter, and the structure that is connected with drawstring increased drawstring adhesive force, used laborsaving, drawstring can freely exchange position, the left and right sides with being connected of pulley, very convenient user, no matter drawstring whipping or upspring is all stopped by anti-knocking over earlier, make it not break away from pulley, have practical value.The kink structure that adjustable ring and drawstring are connected on the hanging ring makes curtain use the adjusting of width to become very easy, has increased the prevalence that the utility model is used greatly.
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is the schematic diagram of drawstring of the present utility model around pulley,
Accompanying drawing 3 is a pulley structure schematic diagram of the present utility model,
The schematic diagram that accompanying drawing 4 connects for the anti-knocking over of the utility model,
Accompanying drawing 5 is that adjustable ring of the present utility model is enclosed within the kink schematic diagram on the drawstring.
Embodiment of the present utility model: on the wheel post (8) of plastic pulley (1) anti-skidding muscle is arranged, one side of pulley (1) has a projection (10), drawstring (3) is enclosed within on the pulley of a side (1), drawstring (3) the both sides pulley of opposite side (1) of ining succession, drawstring (3) rides on this pulley (1) on one side, drawstring (3) another side is from the bottom up around this pulley one circle, adjustable ring (5) is enclosed within on one side, and drawstring (3) upward forms kink (11), kink (11) is enclosed within on the plastics curtain clip (5), and nylon prevents that knocking over (7) entangles drawstring (3), link to each other with the plastics curtain clip (5) on the metal hanger (2).
During use, the pulling drawstring, under the situation that pulley rotates, curtain can be drawn back slowly or closes, because drawstring canoe cleverly, so can not produce winding between the drawstring in the use.
Claims (4)
1, a kind of two-wheel curtain open/close device is made of pulley (1), drawstring (3), hanging ring (5) and outstanding rail (4), hook (2), it is characterized in that: have a side of anti-skidding muscle, pulley (1) that a projection (10) is arranged on the wheel post (8) of pulley (1).
