Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1: the utility model provides a hundred curtains with adjustable height from top to bottom, as shown in fig. 1 and 2, show, including four installation sign indicating number 1 that are the rectangular distribution, two set up respectively between two installation sign indicating numbers 1 of homonymy and along the bead chain 2 of vertical direction extension, two distribute from top to bottom and both ends are close to two track 3 of bead chain 2 respectively, set up the folding curtain 4 between two track 3, four set up respectively at the both ends of two track 3 and be used for fixing the height-adjusting part 5 at the arbitrary height of the bead chain 2 that is close to mutually.

As shown in fig. 3 and 4, the installation code 1 includes a base 11 in an "L" shape, and an adjusting seat 12 adjustably disposed at one end of the base 11 and forming a clamping area 13 with the base 11. The adjusting base 12 is sleeved on one end of the base 11, and a plurality of buckling grooves 111 extending along the length direction of the base 11 are arranged at one end of the base 11. The adjusting base 12 is made of plastic, the adjusting base 12 is integrally provided with a buckling claw 124 embedded in any one of the buckling grooves 111, and the buckling claw 124 is integrally provided with a lifting plate 125 which enables the buckling claw 124 to be separated from the buckling groove 111 after being deformed in the lifting process.

As shown in fig. 3 and 4, the bead chain 2 includes a string 21 and a plurality of beads 22 arranged on the string 21 at intervals. A cavity 121 for embedding one end of the bead chain 2 is formed on the adjusting seat 12, a clamping groove 122 for embedding the part of the pull rope 21 between the two beads 22 and communicating with the cavity 121 is formed on the end surface of the adjusting seat 12 far away from the base 11, and an end cover 123 for covering the cavity 121 is arranged on the adjusting seat 12.

As shown in fig. 3 and 4, the rails 3 are provided with open-ended limiting grooves 31 extending along the length direction thereof, the open-ended limiting grooves 31 of the two rails 3 are close to each other, and the upper and lower ends of the pleated curtain 4 are respectively provided with limiting strips 41 for being inserted into the open-ended limiting grooves 31 of the two rails 3. The two tracks 3 are made of PVC material, the length of the limiting strip 41 is the same as the width of the folding curtain 4, and the limiting strip 41 is also made of PVC material.

As shown in fig. 3 and 4, the pleated curtain 4 is formed by continuous zigzag folding of the fabric.

As shown in fig. 3 and 4, the height adjusting member 5 is a sealing clip 51 with one end inserted and fixed on the end of the track 3 and used for clamping the bead chain 2. The sealing clip 51 covers the opening limiting groove 31; and the part of the sealing clip 51 used for clipping faces the indoor after the pleated curtain is installed; meanwhile, the part of the sealing clip 51 used for clamping the bead chain 2 is integrally provided with the anti-slip strips 511 which are distributed in an arrangement manner, and the cross section of the recess formed between the adjacent anti-slip strips 511 is arc-shaped so as to improve the contact area with the bead 22.

As shown in fig. 1 and 2, while the pleated curtain 4 is maintained in a state of not interfering with the bead chains 2 in a process as the two rails 3 are gradually approached from the farthest distance.

The implementation effect is as follows: a height adjusting piece 5 for fixing at any height of the bead chain 2 is arranged between the end of the track 3 and the bead chain 2, and a folding curtain 4 is arranged between the two tracks 3, so that the folding curtain can be unfolded along with the tracks 3 when the fixed height of the two tracks 3 is changed; finally, sunlight can enter from the upper side of the window to increase brightness, and the lower side of the window is shielded by the folding curtain 4 to prevent human body irradiation or protect privacy, so that different use requirements are met.

Example 2: a pleated curtain with adjustable up-down height, as shown in fig. 5, which is different from embodiment 1 in that: in the process of gradually separating the two rails 3 (refer to fig. 1) from the closest distance, the pleated curtain 4 is maintained in an interference state with the bead chains 2, and the folded ends protruding from one side of the pleated curtain 4 abut against the beads 22 of the bead chains 2. At this time, when the height of the track 3 is adjusted, although smoothness is affected by interference between the pleated curtain 4 and the bead chain 2, the folded end protruding from one side of the pleated curtain 4 abuts against the bead of the bead chain 2, the height of the folded end protruding from one side of the pleated curtain 4 abutting against the bead 22 of the bead chain 2 can be manually adjusted, the pleated curtain 4 is supported by the bead 22, the situation that the top folded part is loose and the bottom folded part is tight under the action of gravity of the pleated curtain 4 is avoided, and the attractiveness in use is improved. Meanwhile, the folding curtain 4 can be deformed, so that the condition that the bead chain 2 is deformed due to excessive extrusion of the bead chain 2 cannot occur in the lifting process of the two tracks 3.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
