Description

Technical Field

[0001] The utility model relates to the technical field of curtains, in particular to a novel screen curtain. Background Art

[0002] Curtains are widely used in people's lives. With the improvement of people's living standards, the requirements for curtains are not only that they must have simple shading and concealing properties, but also that they must have a certain aesthetic value.

[0003] Currently, existing screen curtains all have tracks with more than four slots, and each slot can only hold one curtain piece. The wider the window, the more slots the curtain track has. The more slots the track has, the wider the curtain track will be. This leads to the following limitations:

[0004] 1. The large number of track slots makes track production difficult;

[0005] 2. The more slots there are, the more difficult it is to process, which limits the width of this type of screen curtain and makes it impossible to produce ultra-long specifications;

[0006] 3. The more track slots there are, the wider the track will be, resulting in a huge installation area during on-site installation, thus affecting the aesthetics.

[0007] For this reason, a novel screen curtain is proposed to solve the above-mentioned problems. Utility Model Content

[0008] The utility model provides a novel screen curtain to solve the above-mentioned problems.

[0012] A driving unit connected to the guide rail body and providing a power source for traction of the curtain panel group;

[0013] Among them, the ball channel includes a first channel and a second channel adjacent to the first channel. There are several balls on the top of the curtain plate group. The balls constitute a movable ball part 1 adapted to the first channel and a movable ball part 2 adapted to the second channel. The driving unit drives the movable ball part 1 or the movable ball part 2 on the curtain plate group, and then the curtain plates pull the balls across the adjacent channels, and cooperate with the flexible parts to make the curtain plate group open and close on the guide rail body.

[0014] Furthermore, the flexible member in the curtain plate group is a flexible wire, which is respectively connected in series with the beads in the first channel or the second channel.

[0032] according to Figure 1-8 As shown:

[0033] A novel screen curtain, comprising:

[0034] The guide rail body 100 is provided with a ball bearing channel;

[0035] The curtain blade group 200 moves in the ball bearing channel through the ball bearing 3, and the curtain blade group 200 has a connected flexible member 4 built in;

[0036] The driving unit 300 is connected to the guide rail body 100 and provides a power source for traction of the curtain panel group 200;

[0037] Among them, the ball channel includes a first channel 1 and a second channel 2 adjacent to the first channel 1. A plurality of balls 3 are provided on the top of the curtain plate group 200. The balls 3 constitute a movable ball portion S1 adapted to the first channel 1 and a movable ball portion S2 adapted to the second channel 2. The driving unit 300 drives the movable ball portion S1 or the movable ball portion S2 on the curtain plate group 200, and then the balls 3 across the adjacent channels are pulled by the curtain plate 201, and cooperate with the flexible member 4 to open and close the curtain plate group 200 on the guide rail body 100.

[0038] Specifically, the flexible member 4 is a flexible wire, so that the curtain pieces 201 in this structure are evenly spaced on the guide rail body 100. The flexible members 4 are respectively located in the first channel 1 and the second channel 2, and are connected in series with the beads 3 in the ball channel. The curtain piece group 200 is composed of a starting curtain piece 5 and a matching curtain piece 6 arranged after the starting curtain piece 5, wherein the starting curtain piece 5 is connected to the ball channel through a pulley assembly 7. As shown in the figure, in this structure, the pulley assembly 7 is mostly installed in the outer ball channel, and the outer ball channel is the first channel 1. The pulley assembly 7 is located in the first channel 1 in this structure.

[0039] Specifically, the first channel 1 and the second channel 2 are respectively located in independent guide rails 102 and 103. In this structure, the guide rail body 100 is composed of two groups of guide rails 102 and 103. The two groups of guide rails 102 and 103 are fixed and assembled by mounting codes 101, so that the second channel 2 is adjacent to the first channel 1, and the two side ends of the guide rails 102 and 103 are respectively provided with a drive unit 300 or a head 400. The drive unit 300 is paired with the pulley assembly 7. In this structure, the guide rail 102 with the first channel 1 built in is connected to the drive unit 300.

[0040] Specifically, the driving unit 300 can be electric or manual, and the force-applying end drives the pulley assembly 7 through the control head 500 or the transmission box 600, driving the movable bead part S1 in the first channel 1 to open and close the curtain piece. The force-applying end can be a motor or a hand rope, wherein the transmission box 600 drives the traction member 8 and the pulley assembly 7.

[0041] Specifically, the guide rail body 100 is designed to be straight or curved. As shown in the figure, this structure can not only be opened and closed in two styles: electric or manual, but can also be changed into a straight guide rail body 100 or a curved guide rail body 100 according to scene requirements.

[0042] Specifically, when the guide rail body 100 is arc-shaped, a connecting piece 104 is provided between the guide rails 102 and 103 . As shown in the figure, the connecting piece 104 fastens the two sets of guide rails 102 and 103 to ensure the stability of the arc-shaped structure.

[0043] It should be noted that in this structure, the proposed drive unit 300 and its matching brake head 500 or transmission box 600 are existing traction drive methods. The traction style of the hand rope and the drive motor is not described in this article. The traction member 8 is a transmission belt, and the hand rope is a one-way rope that is controlled by the fixed-axis brake head 500.

[0044] principle:

[0045] The electric screen curtain system is controlled by the control system to drive the motor to rotate forward or reverse. The motor transmits power to the pulley assembly 7 through the transmission belt from the transmission box 600, and drives the pulley assembly 7 to slide. The pulley assembly 7 drives the first curtain piece 5 associated with the pulley to slide, and the curtain piece associated with the pulley assembly 7 drives other curtain pieces to slide through the flexible line (ball 3 line), thereby realizing the opening and closing action of the screen curtain;

[0046] The manual pull-cord screen curtain system is a system in which the pull cord is pulled forward or backward to drive the pulley assembly 7 to slide, thereby the pulley assembly 7 drives the starting curtain piece 5 associated with the pulley to slide, and the starting curtain piece 5 associated with the pulley drives other curtain pieces to slide through the flexible line (ball 3 line), thereby realizing the opening and closing action of the screen curtain.

[0047] The guide rails 102 and 103 are provided with two slots, and all the curtain pieces on the guide rails 102 and 103 can share the same slots to realize free opening and closing. The guide rails 102 and 103 with two slots greatly reduce the production difficulty of the guide rail body 100 and improve the production efficiency. Compared with the old multi-track screen curtain, the specifications of this mechanism are more flexible and the installation area is reduced.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
