Problems solved by technology

Frictional heat is generated between the rotating gear 3' and the rotating shaft 7'. The lock shell 1' is usually made of plastic material. heat, make the lock shell 1' soften or melt, and easily deform, then the service life of the lock will be short
In order to overcome the frictional force between the rotating gear 3' and the rivet of the rotating shaft 7', it is necessary to pull the stay rope 6' with a large force to drive the fast rotation of the rotating gear 3', and the stay rope is laborious to pull.

Embodiment Construction

[0014] The specific structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] see Figure 1-4 Shown, a kind of curtain lock, its lock case 1 has inner cavity 2, and the top of lock case 1 has the connecting base 3 that is used for fixing and installing lock, and lock case 1 has four sidewalls around, and two sides that are arranged opposite The two ends of the rotating member 6 are connected to the side wall of the lock housing through the bearing 15, and the inner surface of one of the side walls is processed into a tooth surface 5 on the other two side walls. The teeth of 5 are arranged continuously along the up and down direction. In this embodiment, as figure 1 or figure 2 As shown, the end of the rotating part 6 is fixed in the inner ring 13 of the bearing, and the outer ring 14 of the bearing is fixed on the side wall of the lockset housing. The frictional force overcome when the rotating part 6 rotates...

Abstract

The invention discloses a curtain lockset which comprises a lockset casing with a cavity. A free gear and a rotating part are arranged in the lockset casing; the central axis direction of the free gear is basically parallel with the rotating axis direction of the rotating part; a tooth surface for causing the free gear to longitudinally roll is arranged on the inner surface of the side wall of the lockset casing; teeth of the tooth surface is matched with the teeth of the free gear; when the free gear is in a clamped condition, the free gear is clamped between the rotating part and the tooth surface; and when the free gear is in a loosened condition, the free gear is separated from the rotating part or the tooth surface, and two ends of the rotating part are respectively connected with the lockset casing through a bearing. The rolling friction force overcome by the rotating part is less when the rotating part is rotated, a guy rope can be conveniently operated with less effort, and the heat quantity released by the friction of the rotating part is less when the rotating part is rotated, the normal service life of the lockset casing can not be affected, and the less friction force during the rotation of the rotating part causes low rotation noise, therefore, the peripheral environment is prevented from being affected.

Description

technical field [0001] The invention relates to a curtain lock, in particular to a curtain lock for positioning a drawstring on a curtain. Background technique [0002] In the prior art, see Figure 5 As shown, the lock case 1' has an inner cavity 2', and two meshable gears are arranged in the lock case 1', one gear 3' is rotatably arranged in the lock case 1' through a rotating shaft 7', and the other gear 4 'Mobilely located in the lock case 1', the inner wall of the lock case 1' has a tooth surface 5', the teeth of the tooth surface 5' mesh with the teeth of the movable gear 4', and the rotating gear 3' and the movable gear 4 The stay rope 6' with curtains passes between ', and the stay rope 6 drives the movable gear 4' to roll up and down on the tooth surface 5'. The movable gear 4' has a clamping state and a loosening state. When the movable gear 4' is in the In the clamping state, the movable gear 4' is stuck between the rotating gear 3' and the tooth surface 5', and ...
