Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific embodiment:

[0022] refer to figure 1 with figure 2 A sliding window safety lock based on a ratchet and rack and pinion structure shown includes: a lock frame 1 , an inner rack 15 , an outer rack 3 and a wedge-shaped slider 2 .

[0023] The lock frame 1 includes a base 101 and a chute 102 disposed under the base 101 , the chute 102 is integrally formed with the base 101 .

[0024] The top of the base 101 is fixed with an inner support plate 103 , a middle support plate 104 and an outer support plate 105 in sequence.

[0025] The inner support plate 103 is equipped with the inner gear set 4, specifically the inner first gear 5, the inner central gear 6 and the inner second gear 7, and the inner central gear 6 meshes with the inner first gear 5 and the inner second gear 7 respectively. .

[0026] The outer support plate 105 is equipped with an outer gear set 14, specifically an outer ...

Abstract

The invention relates to a safety lock for sliding windows based on a ratchet and rack and pinion structure. It mainly upgrades the safety locking function of the sliding window. The lock frame is connected with the chute at the bottom of the window frame as a whole, and the bottom of the inner and outer sash is installed Rack, the rack meshes with the gear set on the lock, and the ratchet pawl does not affect the free opening and closing of the window under normal conditions. When locking is required, push the wedge-shaped slider at the bottom of the lock to lift up the corresponding top block, and the top block overcomes the spring tension of the ratchet pawl , release the ratchet claw, block the ratchet coaxial with the corresponding gear, fix the corresponding gear set, and realize the locking of the window; the invention has the function of realizing the locking of the sliding window and the synchronous or asynchronous locking of the inner and outer windows when the sliding window is opened, and the triggering method is simple. The overall structure is tight and reliable, which improves the user experience.

Description

technical field [0001] The invention relates to the field of architectural window locks, in particular to a safety lockset for sliding windows based on a ratchet and rack and pinion structure. Background technique [0002] Most modern windows are composed of three parts: window frame, transparent part and movable components (hinges, handles, pulleys, etc.); the window frame is responsible for supporting the main structure of the window, the transparent part is attached to the window frame, and the movable components are mainly made of metal The material is the main material, and it may also be wrapped with plastic and other heat-insulating materials where it is touched by human hands; and the window lock is also one of the important components. The traditional sliding window lock has the defect that it can only be locked when the window is closed. Safety and ventilation You can't have it both ways. Contents of the invention [0003] The object of the present invention is ...
