Description

Technical Field

[0001] The utility model relates to the technical field of curtain accessories, and more specifically to a safety pull rod for a manual curtain. Background Art

[0002] Existing curtains generally include manual curtains and electric curtains. Many of the manual curtains are operated by beaded ropes, referred to as beaded curtains. Common beaded curtains include beaded roller curtains, beaded venetian blinds, beaded cloth curtains, and the like. When operating the curtain mechanism, the beaded rope is pulled to drive the beaded wheel in the control head to rotate, so that the roller curtain fabric moves up and down. However, the beaded rope is usually not fixed, which makes it easy to swing and make noise, and the beaded rope is easy to get tangled, affecting its use. At the same time, when children use or play, there are certain safety hazards, which can easily entangle the children's hands or other parts, causing unnecessary dangers. Therefore, a safety device needs to be set to solve the above problems. At the same time, how to ensure the smooth sliding of the beaded rope after setting the safety device is also a problem that needs to be considered. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] This embodiment discloses a safety pull rod for a manual curtain, such as Figure 1-7 As shown, the invention comprises a rod body 1, on which a bead groove A2 and a bead groove B3 for accommodating a bead rope of a curtain are arranged, a bead steering member 4 and a bead guide member 5 are arranged at both ends of the rod body 1, a steering channel 401 is arranged in the bead steering member 4, the steering channel 401 connects the bead groove A2 and the bead groove B3, and a guide hole 501 for the bead rope to pass through is arranged on the bead guide member 5; a slidable rod sleeve 6 is arranged on the rod body 1, and buttons A601 and B602 corresponding to the bead groove A and the bead groove B are arranged on the rod sleeve 6, and claws 7 are arranged in the buttons A601 and B602, and the claws 7 are engaged with the bead rope. Through the above structure, the left and right sections of the bead rope are constrained in the bead groove A and the bead groove B, so that the bead rope can be prevented from shaking at will and being entangled with each other, and the danger of entanglement when children use or play can be avoided, thereby improving the convenience and safety of use.

[0023] Furthermore, the guide hole 501 of the bead guide 5 includes a first channel 5011, a second channel 5012, and a partition protrusion 5013 between the first channel 5011 and the second channel 5012, and a chamfered structure 5014 is provided on the first channel 5011 and the second channel 5012. Through the above structure, when the bead on the bead rope enters the guide hole 501, it will first pass through the guidance of the chamfered structure 5014 and the partition protrusion 5013, and then enter the first channel 5011 and the second channel 5012, thereby avoiding the bead rope from getting stuck when entering the pull rod body 1, ensuring smooth sliding and better user experience.

[0024] Further, see Figure 7A limit stopper 8 is provided on both the bead steering member 4 and the bead guide member 5, and a limit convex block 9 is provided on the rod sleeve 6, which protrudes toward one side of the bead groove A and the bead groove B, and the limit convex block 9 abuts against the limit stopper 8. Through the cooperation of the limit stopper 8 and the limit convex block 9, the rod sleeve 6 is constrained between the bead steering member 4 and the bead guide member 5 when sliding, so as to prevent the rod sleeve 6 from slipping out of the rod body 1 when sliding.

[0025] Further, see Figure 5-6 , a mounting plate 10 is arranged inside the rod sleeve 6, buttons A 601 and B 602 are both mounted on the mounting plate 10, and a reset spring 13 is abutted between buttons A and B and the mounting plate 10, and at the same time, a through hole 11 is arranged on the mounting plate 10 for the claw 7 to pass through, and the claw 7 includes three groups of clamping plates 701 arranged side by side, and the clamping plates 701 are provided with concave openings 7011, and the concave openings 7011 are used to accommodate the pull rope of the bead rope, and the three groups of clamping plates 701 are used to accommodate the beads of the bead rope. Through the above arrangement, when in use, the operator selectively presses button A or button B, and the corresponding clamping claw 7 clamps the bead rope, and then slides the rod sleeve, which can drive the bead rope in the bead groove A or the bead groove B to move, thereby playing the function of controlling the bead rope, and when both buttons are not pressed, the rod sleeve slides freely. Specifically, when in use, slide the pull rod sleeve 6 to a position close to one end of the bead guide 5 without pressing the button, then press button A or button B to pull the pull rod sleeve 6, and then release the button, and slide the pull rod sleeve 6 to a position close to one end of the bead guide 5 again, and repeat this process to continuously pull the bead rope.

[0026] Furthermore, it also includes a curtain head 12, which is arranged at one end of the bead guide 5 of the pull rod body 1. A bead wheel is provided in the curtain head 12, and the bead wheel is adapted to the bead rope of the curtain. At the same time, the bead wheel also cooperates with the curtain tube (not shown in the figure). In this way, when the bead wheel is driven by the bead rope, the curtain tube is also driven, thereby realizing the lifting and lowering of the curtain.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
