Abstract

A kind of dual-purpose lock of casement window offers axis hole in the upper end of jam plate, is provided with positioning pin in the rear plate face of jam plate, and the annular enclosure wall of protrusion is provided on the front face of jam plate, offered slot on the left side wall side of jam plate enclosure wall.Two through-holes up and down are offered respectively in the upper and lower ends of fulcrum bearing, offer limiting slot on the front face of fulcrum bearing.Fulcrum bearing is connected on window frame by the lower end through-hole that screw passes through fulcrum bearing, and the top of fulcrum bearing is arranged in jam plate, and in the limiting slot in positioning pin insertion fulcrum bearing on jam plate, the through-hole that screw shaft passes through axis hole and fulcrum bearing upper end on jam plate is connect with window frame.Tapered end when closing sash on sash may pass through slot and enter in the enclosure wall of jam plate, and when tapered end is moved upward to the upper end position of jam plate, tapered end can cooperate jam plate to lock sash.When tapered end is moved downward to the lower end position of jam plate and opens sash, tapered end can be driven jam plate and rotate around screw shaft, and the sash that therefore locking low-angle is opened.

Description

The dual-purpose lock of casement window

Technical field

The utility model relates to a kind of window lock, it can especially close locking and being opened flat for sash is opened in low-angle positioning The dual-purpose lock of window.

Background technique

Currently, the well known window lock buckle that is opened flat is stationary structure, therefore the sash that can only be locked and closed, and cannot be to small angle The sash that degree is opened is positioned.

Summary of the invention

In order to overcome the shortcomings of that existing casement window latching function is single, the utility model provides a kind of casement window dual-purpose lock Button, the dual-purpose lock of the casement window can close locking sash but also sash is opened in low-angle positioning.

The technical scheme adopted by the utility model to solve the technical problem is as follows: the utility model include jam plate, positioning pin, Cross slot, fulcrum bearing, limiting slot, screw shaft, screw and tapered end.

Jam plate is longitudinally disposed Rectangular Plate Structure, offers the axis hole vertically through jam plate in the upper end of jam plate, is locking The center of plate face is provided with positioning pin after plate, and the positioning pin is the column structure perpendicular to jam plate.In jam plate foreboard The peripheral position in face is provided with the annular enclosure wall of protrusion, offers on the left side wall side of jam plate enclosure wall and the axis hole phase on jam plate It is corresponding to cross slot.Fulcrum bearing is longitudinally disposed Rectangular Plate Structure, is offered respectively in the upper and lower ends of fulcrum bearing through bearing Two through-holes up and down of seat, offer limiting slot corresponding with the positioning pin on jam plate on the front face of fulcrum bearing, described Limiting slot be the groove type structure for opening fulcrum bearing front face to the left.Fulcrum bearing is arranged on window frame, and screw passes through fulcrum bearing Lower end through-hole connect with window frame, the top of fulcrum bearing is arranged in jam plate, the limit in positioning pin on jam plate insertion fulcrum bearing In slot, the through-hole that screw shaft passes through axis hole and fulcrum bearing upper end on jam plate is connect with window frame, crosses slot and window on jam plate enclosure wall The tapered end fanned on lockset is corresponding.

Tapered end when closing sash on sash may pass through the slot of crossing on jam plate and enter in the enclosure wall of jam plate, when tapered end is upward When being moved to the upper end position of jam plate, the enclosure wall on jam plate can cooperate tapered end to lock sash.When tapered end is moved downward to jam plate Lower end position and when opening sash, tapered end can drive jam plate rotate around screw shaft and make the positioning pin on jam plate by enclosure wall It is exited from the limiting slot in fulcrum bearing.When jam plate stops operating, tapered end can cooperate the enclosure wall on jam plate to lock low-angle The sash of unlatching.

The utility model has the beneficial effects that locking sash but also low-angle positioning unlatching sash can be closed.

Specific embodiment

In Fig. 1, Fig. 2, Fig. 3, jam plate 1 is longitudinally disposed Rectangular Plate Structure, offers in the upper end of jam plate 1 and vertically passes through The axis hole of logical jam plate 1, the center of plate face is provided with positioning pin 3 after jam plate 1, and the positioning pin 3 is perpendicular to jam plate 1 Column structure.The peripheral position of 1 front face of jam plate is provided with the annular enclosure wall of protrusion, on the left side wall side of 1 enclosure wall of jam plate On offer it is corresponding with the axis hole on jam plate 1 cross slot 4.Fulcrum bearing 7 is longitudinally disposed Rectangular Plate Structure, in fulcrum bearing 7 Upper and lower ends offer two through-holes up and down through fulcrum bearing 7 respectively, offered on the front face of fulcrum bearing 7 and jam plate The corresponding limiting slot 6 of positioning pin 3 on 1, the limiting slot 6 are the groove type structure for opening 7 front face of fulcrum bearing to the left. Fulcrum bearing 7 is arranged on window frame, and the lower end through-hole that screw 5 passes through fulcrum bearing 7 is connect with window frame, and fulcrum bearing 7 is arranged in jam plate 1 Top, the positioning pin 3 on jam plate 1 are inserted into the limiting slot 6 in fulcrum bearing 7, and screw shaft 2 passes through axis hole and bearing on jam plate 1 The through-hole of 7 upper ends of seat is connect with window frame, and the slot 4 excessively on 1 enclosure wall of jam plate is corresponding with the tapered end 8 on sash lockset.

In Fig. 1, Fig. 4, Fig. 5, the tapered end 8 when closing sash on sash may pass through the slot 4 of crossing on jam plate 1 and enter jam plate In 1 enclosure wall, when tapered end 8 is moved upward to the upper end position of jam plate 1, the enclosure wall on jam plate 1 can cooperate 8 locking window of tapered end Fan.When tapered end 8 is moved downward to the lower end position of jam plate 1 and opens sash, tapered end 8 can by enclosure wall drive jam plate 1 around Screw shaft 2 rotates and exits the positioning pin 3 on jam plate 1 from the limiting slot 6 in fulcrum bearing 7.When jam plate 1 stops operating, The sash that tapered end 8 can cooperate the locking low-angle of the enclosure wall on jam plate 1 to open.
