Abstract

The utility model provides a push window lock, which is characterized in that a door sill 1a is arranged on a sheath 1; a thumbing plate 2a swingingly matching with the door sill 1a is arranged on the lower end part of a thumbing plate 2; a spacer pin 3 is arranged on the sheath 1; a restoring spring 4 adopts a torsion spring; the restoring spring is sheathed with the spacer pin 3; both ends of the spring wire tightly press the back of the thumbing plate 2; a lock hook 5 is fixed on the thumbing plate 2 through screws; the appearance of the plastic thumbing block 6 is arcuate. Compared with prior art, the utility model has the advantages of reasonable structure, less consumable material, easy technique, high working efficiency, dependable performance and beautiful appearance, being suitable for various windows and doors.

Description

Lock for windows

Technical field

The utility model relates to a kind of hasp lock, the lock for windows that particularly a kind of window is used.

Background technology

Existing lock for windows by epitheca, press plate, spacer pin, back-moving spring, latch hook, pin, plastics and press piece and constitute, press and adopt pin to be connected between plate and the epitheca, back-moving spring is a cylindrically coiled spring, and this spring is arranged in away from plastics and presses near the pin of piece, and it is square that plastics are pressed piece.Its defective of existing lock for windows is: back-moving spring is pressed piece away from plastics, makes that to press the block reset reliability relatively poor, influences the window locking effect, lacks aesthetic feeling in appearance simultaneously, and the pin used in the junction of pressing plate and epitheca can't omit.

Summary of the invention

The purpose of this utility model is to provide a kind of lock for windows of novel structure, and the locking that can overcome existing lock for windows is unreliable, and the defective of aesthetic appearance difference reduces required parts, process easy, the raising of locking reliability, its outward appearance create an aesthetic feeling.

A kind of lock for windows, comprise epitheca 1, press plate 2, spacer pin 3, back-moving spring 4, latch hook 5 is embedded with plastics and presses piece 6 pressing plate 2 upper ends, it is characterized in that: epitheca 1 is provided with threshold 1a, the bottom of pressing plate 2 is provided with threshold 1a makes the prong 2a that swing cooperates, and spacer pin 3 is arranged on the epitheca 1, and back-moving spring 4 adopts torque spring, this back-moving spring is sleeved on the spacer pin 3, the two ends of spring wire are pressed on the back of pressing plate 2, and latch hook 5 is being pressed on the plate 2 by screw, and being embedded in the plastics of pressing plate 2 upper ends, to press piece 6 its profiles be arch.

With prior art relatively, the utility model has the advantages that: 1) structure more becomes reasonable, consumptive material is few, technology is easy, originally need compression spring,, changed the torque spring of little moment into owing to changed spring action point position and mode with big moment, save simultaneously the material of big moment spring base installation position fully, also reduced spring material; 2) saved one of pivot pin, one on axle sleeve, also reduced simultaneously operations such as accounting for axis hole, ream counterbore and riveted joint, because pendulum angle is only in 10 ° of scopes when pressing plate work, so can replace pivot structure with the structure of a kind of " riding threshold " form fully, be provided with the prong that straddles shape on the plate pressing, once property extrusion molding on the aluminium extruded sections extrusion shaping machine, so need not other processing, and the threshold on the lock for windows epitheca when the plate window is pressed in punching out in passing punching out form, so work efficiency is higher; The installation of pressing plate as shown in Figure 2, use spacing punch die punching press in the direction of arrows, the prong opening degree of pressing on the plate is diminished, press plate and can on the threshold of epitheca, ride the jail, can in 10 ° of scopes, swing flexibly again and can not break off relations, limit the axle center pin of the spacer pin double as torque spring of pressing the piece pivot angle; 3) plastics of pressing plate upper end are pressed and are pressed plate on piece and the epitheca and cooperate, and are the dome-shaped arc-shaped window according to the shape of finger tip, and finger tip is pressed and touched convenience; 4) good looking appearance.

The specific embodiment

Embodiment:

A kind of lock for windows, adopt structure as shown in Figure 1, the length and width height is 23 * 35 * 120m, pressing plate 2 length is 76mm, pressing the plate pendulum angle is 10 °, and plastics are pressed piece 6 and adopted the punching out of coloured plastics material plate to form, and epitheca adopts die-cut the forming of rectangular segmentation of aluminium alloy extrusions, extrusion molding, press plate and also form, limit the axle center pin of the spacer pin 3 double as torque springs of pressing plate 2 pivot angles by rectangular aluminium alloy extrusions is die-cut.The installation of pressing plate 2 as shown in Figure 2, use spacing punch die punching press in the direction of arrows, the prong 2a opening degree of pressing on the plate is diminished, guarantee that prong 2a and threshold 1a can not break off relations, lock for windows and the hasp that cooperates with it are installed in respectively on window and the window frame, perhaps being installed in two respectively fans on the window of coupling mutually, when closing window, window is in the lock state, and the pressing plastics are pressed piece, then latch hook breaks away from hasp, and window just can be pushed open.

Claims

1. lock for windows, comprise epitheca (1), press plate (2), spacer pin (3), back-moving spring (4), latch hook (5), be embedded with plastics and press piece (6) pressing plate (2) upper end, it is characterized in that: epitheca (1) is provided with threshold (1a), and the bottom of pressing plate (2) is provided with threshold (1a) makes the prong (2a) that swing cooperates, and spacer pin (3) is arranged on the epitheca (1), back-moving spring (4) adopts torque spring, this back-moving spring is sleeved on the spacer pin (3), and the two ends of spring wire are pressed on the back of pressing plate (2), and latch hook (5) is being pressed on the plate (2) by screw.
