Window curtain lockset

Abstract

The invention discloses a curtain lockset, which comprises a lockset shell with an inner cavity, wherein the lockset shell is provided with two gears capable of being meshed inside; one gear is rotatably arranged in the lockset shell, and the other gear is movably arranged in the lockset shell; the inner surface of the side wall of the lockset shell is provided with a gear surface on which the movable gear can roll up and down; the teeth of the gear surface and the teeth of the movable gear are arranged in a matching way; the movable gear has a clamping state and a loosening state, when the movable gear is in the clamping state, the movable gear is clamped between the rotatable gear and the gear surface; when the movable gear is in the loosening state, the movable gear is separated from the rotatable gear or the gear surface; and the side wall of the lockset shell with the gear surface is provided with a reinforcer. When the movable gear is stably clamped between the gear surface and the rotatable gear, the gear surface is stressed and easy to crack. The side wall with the gear surface is provided with the reinforcer, so that the stress strength of the gear surface is increased to prevent the cracking of the position and prolong the service life of the lockset.

Description

technical field [0001] The invention relates to a curtain lock, in particular to a clamping device for a drawstring on a curtain. Background technique [0002] In the prior art, see figure 1 -4 shows, figure 1 with figure 2 Shows the lock case used on the curtain, image 3 with Figure 4 It is a cross-sectional view of the lock, showing the two states of the curtain pull cord being clamped and released in the lock. The lock shell 1' has an inner cavity 2', and there are two meshable gears inside the lock shell 1', one gear 3' is rotatably set in the lock shell 1' through the rotating shaft 4', and another gear 4' is movably set in the lock shell 1'. There is a tooth surface 5' on the inner wall of the lock shell 1', and the tooth surface 5' The teeth of the movable gear 4' are engaged with the teeth of the movable gear 4', and the pull rope 6' with curtains passes between the rotating gear 3' and the movable gear 4', and the pull rope 6' drives the movable gear 4' up a...

AI Technical Summary

Problems solved by technology

based on Figure 4 In the state of the curtain drawstring 6' as shown, pull the drawstring 6' downward, and the drawstring 6' drives the movable gear 4' to roll upward along the tooth surface 5', depending on the elastic deformation of the side wall with the tooth surface 5', Through the meshing of the teeth, the movable gear 4' is stuck between the rotating gear 3' and the tooth surface 5'. Due to frequent deformation, the tooth surface 5' or the side wall with the tooth surface is relatively fragile and easy to crack , very short service life
