Detailed ways

The specific embodiment of the present invention will be described in further detail below in conjunction with accompanying drawings 1-9.

The connecting part of the present invention: the curtain rod of the curtain frame is divided into three sections, the two ends are short rods 2, and the middle is a long rod 1, both of which are designed as hollow structures, and the ends of the short rods 2 away from the long rod 1 are closed , while reducing the overall weight, it meets the design of connecting the short rod 2 and the long rod 1 of the curtain with the pin 7. The hollow structure of the long rod 1 is equivalent to that the pins 7 at both ends are inserted into the slots 4 to communicate with each other, while the slots 3 for the pins 7 of the short rod 2 constitute the hollow structure of the short rod 2 . We designed the short rod 2 and the long rod 1 of the curtain frame into a notched shape to ensure that the short rod 2 can be accurately positioned and connected to the long rod 1 when it rises. When the short rod 2 of the curtain frame rises to the designated position The column pin 7 in the short rod 2 enters the long rod 1 to complete the connection and fixation of the short rod 2 and the long rod 1 . As can be seen from the following two figures, when the pin 7 is retracted, it will extend out of the opening of the short rod 2 to be flush with the outermost end of the short rod 2, so that the upper surface of the pin 7 is aligned with the long rod 2 when the short rod 2 rises. The extended part of the rod 1 is in contact with the inner wall of the tube, which enables the short rod 2 and the long rod 1 to accurately complete the positioning before connection. It can be seen that there is a baffle at a certain distance inside the long rod 1, which is used to control the length of the column pin 7 to rise, so as to ensure that the length of the column pin 7 in the short rod 2 and the long rod 1 is equal to achieve the best connection. solid state.

There is a spring 8 at the short rod 2 inner pin 7 afterbody, and a reed 9 is equipped with on the short rod 2 bottom, and two pins are arranged on the reed 9. Wherein the short pin is to fix the reed 9 on the outer wall of the short rod 2, and the long pin 11 is used to fix the retracted column pin 7. There is a through hole 12 on the outer wall of the end cover at the position of the long pin 11. When the pin 7 is in the retracted state, the long pin 11 snaps into the limiting groove 13 at the bottom of the pin 7 to limit the ejection of the pin 7. When the short rod 2 rises to match with the long rod 1, since the end of the reed 9 is connected with a top block 10 protruding upwards from the top of the long rod 1, the top block 10 touches the long rod 1 during the rising of the short rod 2 At the bottom, the top block 10 is moved downward by the bottom of the long rod 1 so that the reed 9 is pushed away by the long rod 1, and the column pin 7 breaks away from the restriction of the long pin 11. Under the action of the tail spring 8, the short rod 2 is ejected and rises into the long rod The connection is done in pole 1. When the curtain needs to be changed and washed, the curtain is retracted on the short rod 2, and the stay rope 15 at the end of the short rod 2 is pulled downward, the column pin 7 retracts, the short rod 2 descends, and the long pin 11 is re-engaged in the column pin 7 to complete the short rod 2 and Separation of the long pole 1. The reed 9 is arranged on the part of the lower side of the short rod 2 close to the long rod 1, and the end of the reed 9 away from the long rod 1 is fixed on the lower side wall of the short rod 2 through an end pin, and the reed 9 faces the long rod 1 One end protrudes from the end of the short rod 2. The stay cord 15 hangs down naturally after the guide pulley 17.

Lifting part of the present invention: the lifting structure is to adopt steel wire rope to be connected on the terminal post of short bar 2, go around fixed pulley 19 and wind on the wire wheel 20, control the lifting of short bar 2 by the rotation of wire wheel 20. And the power that wire wheel 20 rotates is driven by bead sprocket wheel 21 and bead chain 22. The role played by the bead chain 22 is the same as that of the chain drive, but considering that it is used on the curtains in the family, it needs to be more attractive, so the form of the bead chain 22 is adopted. The lower end of the bead chain 22 is connected with the hand wheel, so that the user can easily rotate the sprocket on the ground to realize the rotation of the wire wheel 20 so as to control the lifting of the short rod 2 of the curtain. When the bead chain 22 is connected to the handwheel, a bead chain wheel is also coaxially connected on the hand wheel, and the bead chain is set between the upper and lower two bead chain wheels. Pulley, line wheel 20 and bead sprocket wheel 21 all are to hang on the curtain top cover.

Top cover part among the present invention: Considering that the curtain frame and the curtain buckle 25 are exposed outside and affect the appearance, and some mechanisms of the curtain frame can be affected by the entry of foreign objects and affect normal use, so a curtain cover 23 is added on the curtain frame. Simultaneously curtain frame also provides pulley, bead sprocket wheel 21 and line wheel 20 suspension positions. At the same time, the two ends of the curtain cover 23 are designed with both side baffles, which can prevent the short rod 2 from being bounced off the correct matching position by the reverse force when the column pin 7 is ejected into the long rod 1. The guide pulley 17 at the end of the short rod 2 cooperates with the curtain cover 23 when the curtain rises to the position about to cooperate with the long rod 1 and can also play a guiding role in the cooperation of the long and short rod 2 in the horizontal direction.

The curtain buckle 25 part among the present invention, in order to realize simultaneously the hoisting and lifting of the short rod 2 of the curtain and the free pulling of the curtain on the long and short rod 2, we have also carried out a unique design to the curtain buckle 25. The design of the C-shaped curtain buckle 25 is adopted, and the C-shaped opening faces the wall. Such a design not only enables the curtain to smoothly pass through the connection between the long rod 1 and the wall, but also smoothly pulls between the long rod 1 and the short rod 2 . Moreover, such a structural design can make the loading and unloading of the curtain easier, and is suitable for almost all curtains on the market today. In the case of some narrow windows, such as in the bathroom. We can change the design of two short rods 2 plus one long rod 1 of the curtain frame to the structure of one short rod 2 plus one long rod 1. Thanks to the design of the C-shaped curtain buckle 25, the curtain can be placed on the curtain rod Unobstructed, which further enhances the usability of this curtain rack. The curtain 25 button is C-shaped, and the opening of the curtain button is towards the rear side wall of the curtain cover. Both the hook part 25-1 and the pull hook part 25-2 are arc-shaped, and can be connected through the connecting arm 25-3.

The bead sprocket 21 in this invention includes a wheel body, and the outer surface of the wheel is uniformly distributed with a set of teeth along the circumference, and the set of teeth is composed of two active teeth radially spaced on the outer surface of the wheel. , the outer sides of the opposite surfaces of the two active teeth of the tooth group are in a circular arc transition. The sprocket fits within the interval between the two active teeth of the tooth set. The bead wheel has a shell, and a passage hole passing through the bead is opened at the lower part of the shell. The front end portion of the cancellation in this invention is in the shape of a circular platform with a small front and a large rear, which is convenient to extend into the pin 7 and snap into the slot 4 .

When the present invention is in use, when the curtain needs to be pulled down, the curtain buckle 25 of the curtain is slid onto the short rods 2 on both sides. The opening can cross the connecting plate 24 connected between the long rod 1 and the wall or the rear side wall of the curtain cover 23, and for the two connecting columns 16 of the short rod 2, one is an outer connecting column 16, and the other is an inner connecting column 16, Fix connecting rod on short rod 2 facing body of wall side, inner connecting column 16 is fixed on this connecting rod, and outer connecting column 16 is directly fixed on short rod 2 upper ends and gets final product. Make the opening of curtain buckle 25 also can cross connecting rod and can not cross outer connecting post 16 like this, make curtain buckle 25 promptly can slide on the short bar 2, have avoided again curtain buckle 25 outwards slipping out short bar 2. After sliding the curtain buckle 25 onto the short rods 2 on both sides, pull the stay cord 15, so that the column pin 7 overcomes the elastic force of the spring 8 and retracts toward the short rod 2, and then controls the lifting device. When the short rod 2 descends, the top After the block 10 is separated from the long rod 1, the long pin 11 is snapped into the limit groove 13 in the column pin 7, and the column pin 7 is locked in the short rod 2. At this time, the stay cord 15 can be released to control the short rod. 2 After descending, take off the curtain buckle 25 and get final product. When curtains need to be installed, the curtains are installed on the curtain buckle 25 first, then the curtain buckles 25 of the curtains on the left and right sides are respectively installed on the short rods 2 on the left and right sides corresponding to it, and then the short rods 2 are raised through the lifting device. During the rising process of the short rod 2, first the first notch 5 and the second notch 6 move relatively toward the buckling direction, and when the top block 10 pushes against the long rod 1, the long rod 1 deflects one end of the reed 9 downward. Move, make long pin 11 break away from limit groove 13 downwards, under the effect of spring 8, release column pin 7, column pin 7 stretches in the long bar 1 so that upper short bar 2 is connected as a whole to form curtain rod.
