Blind Stopper

Abstract

To provide a blind stopper having a simple structure and reducing the probability of breakage. The blind stopper has limit beads 90 on the blind transmission strip 50, limit protrusions 91 on the limit beads, and a limit plate 101 that engages with the limit protrusions in the stopper fixing seat 100, which controls the reversal limit of the transmission strip when the speed control knob 80 is operated to rotate the transmission strip. In other words, the reversal limit of the blind sheet is controlled simultaneously, effectively preventing over-rotation of the transmission strip and the blind sheet.

Description

[Technical Field]

[0001] The present invention relates to the field of blind technology, and more particularly to a blind stopper. [Background technology]

[0002] The rotating rod of commercially available PVC blinds can rotate infinitely, but once the blades reach their limit, they will not move and the rotating rod will still be able to rotate, which is likely to cause damage to the blades or the rotating rod will rotate too far and not be able to reset, shortening the service life of the product and creating a poor user experience. Therefore, further improvements to the blind structure are needed. Summary of the Invention [Problem to be solved by the invention]

[0003] In view of this, the present invention provides a blind stopper and solves the conventional technical problems by designing limit beads. [Means for solving the problem]

[0004] The object of the present invention is achieved by the following technical means:

[0005] A blind stopper, comprising: an upper frame, two rotating ladder rope holders, a transmission strip, a rotation adjuster, and a limit bead; The head frame is used to mount the lifting and rotating members of the blinds, The two rotating ladder rope holders are rotatably mounted on both ends of the upper frame by holder mounting seats, and both are connected to the sides of all blind sheets via connecting wires. By rotating and pulling the connecting wires, the blind sheets are pulled and rotated. The transmission strip passes through the center of the two rotating ladder rope holders and is fixedly connected to the two rotating ladder rope holders; The rotation adjuster is fixed to one end of the upper frame and is located outside the rotating ladder rope holder, the transmission strip passes through the rotation adjuster movably, and a gear is fixed to the rotation adjuster, a speed control knob is rotatably mounted in a hole on the side of the rotation adjuster, and a screw thread is provided at the top end of the speed control knob to engage with the gear and transmit power, and when the speed control knob rotates, it rotates the gear, thereby rotating the transmission strip, The limit bead is provided at one end of the upper frame by a stopper fixing seat and is located inside the rotating ladder rope holder, the transmission strip passes through the center of the limit bead and is fixedly connected to the limit bead, the limit bead is provided with a limit protrusion, and a limit plate is provided in the stopper fixing seat to correspondingly lock the limit protrusion.

[0006] Furthermore, an operating ring is provided at the bottom of the speed control knob, and the speed control knob can be rotated by inserting a rotating rod into the operating ring. [Effects of the Invention]

[0007] The beneficial effects of the present invention are as follows: The present invention designs a limit bead on the blind transmission strip, provides a limit protrusion on the limit bead, and provides a limit plate in the stopper fixing seat to correspondingly lock the limit protrusion. When the speed control knob is operated to rotate the transmission strip, the reversal limit of the transmission strip is controlled, that is, the reversal limit of the blind sheet is controlled at the same time, which can effectively prevent the transmission strip and the blind sheet from over-rotating. The structure is simple, the probability of damage is reduced, the user experience is better, and it is more favorable for the popularization and use of the product.

Furthermore, the following examples and features in the examples can be combined with each other if there is no conflict. All other embodiments obtained by those skilled in the art based on the examples in the present disclosure without the need for creative work fall within the scope of protection of the present disclosure.

[0011] In order to prevent the over-rotation of the transmission strip and blind sheet, the specific contents of the present invention are as follows:

[0012] As shown in Fig. 1 and Fig. 2 in combination, the embodiment of the present invention is a blind stopper, and the important points are as follows: It comprises an upper frame 10, two rotating ladder rope holders 30, a transmission strip 50, a rotation adjuster 60, and a limit bead 90. The head frame 10 is used to mount the lifting and rotating members of the blinds. The two rotating ladder rope holders 30 are rotatably mounted on both ends of the upper frame 10 by holder mounting seats 40, and both are connected to the sides of all the blind sheets via connecting wires. The rotating ladder rope holders 30 rotate to wind up the blind sheets, then release the connecting wires, and rotate and pull the connecting wires to pull and rotate the blind sheets. The transmission strip 50 passes through the center of the two rotating ladder rope holders 30 and is fixedly connected to the two rotating ladder rope holders 30, and the rotation of the transmission strip 50 rotates the two rotating ladder rope holders 30; The rotation adjuster 60 is fixed to one end of the upper frame 10 and is located outside the rotating ladder rope holder 30. The transmission strip 50 can movably pass through the rotation adjuster 60. A gear 70 is fixedly mounted on the rotation adjuster 60. A speed control knob 80 is rotatably mounted in a hole on the side of the rotation adjuster 60. The upper end of the speed control knob 80 is provided with a screw thread that engages with the gear 70 to transmit power. When the speed control knob 80 rotates, the gear 70 is rotated, which in turn rotates the transmission strip 50. The limit bead 90 is mounted on one end of the upper frame 10 by a stopper fixing seat 100 and is located inside the rotating ladder rope holder 30. The transmission strip 50 passes through the center of the limit bead 90 and is fixedly connected to the limit bead 90. The limit bead 90 is provided with a limit protrusion 91, and a limit plate 101 is provided in the stopper fixing seat 100 to correspondingly lock the limit protrusion 91.

[0013] The main features of this invention are as follows: a limit bead 90 is designed on the blind transmission strip 50, the limit bead 90 is provided with a limit protrusion 91, and a limit plate 101 is provided in the stopper fixing seat 100 to correspondingly lock the limit protrusion 91, so that when the speed control knob 80 is operated to rotate the transmission strip 50, the reversal limit of the transmission strip 50 is controlled, that is, the reversal limit of the blind sheet is controlled at the same time, which can effectively prevent the transmission strip 50 and the blind sheet from over-rotating, has a simple structure, reduces the probability of damage, improves the user experience, and is more conducive to the popularization and use of the product.

[0014] Furthermore, in some embodiments, as shown in FIG. 2, an operating ring 81 is provided at the bottom of the speed adjuster knob 80 to make it easier for the user to operate the speed adjuster knob 80, and the speed adjuster knob 80 can be rotated by inserting a rotating rod 110 into the operating ring 81.

[0015] The above is intended to describe the embodiments of the present invention, but is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made by those skilled in the art without creative work should fall within the scope of protection of the present invention, as long as they do not deviate from the spirit and principles of the present invention.
