Description

Push button automatic safe lock

(1) technical field

The utility model relates to a kind of lockset, especially a kind of push button automatic safe lock that is mainly used in alumium alloy door and window.

(2) background technology

Conventional aluminum alloy sash lock adopts push-pull structure, generally is located at window left and right side frame and sash left and right side frame place, and when pushing buckling parts open, window is opened; When window was closed, the push-and-pull buckling parts promptly pinned.

(3) summary of the invention

The purpose of this utility model is to provide a kind of incorporate push button automatic safe lock of shutting of alumium alloy door and window that is mainly used in.

The utility model is set latch, following plug housing, following latch spring, pull bar, stator, activity template, fixed screw spare, button, push-button socket and button connecting rod, and following latch is located at down on the plug housing, and following latch spring is placed in down in the bolt rod of latch.The upper end of bolt rod under the following termination of pull bar, the upper end of the pull bar moving plate of taking over a job, the last termination fixed screw spare of activity template, the lower end of activity template contacts mutually with the end of button spindle, and the top and the button of button spindle join, and button and button spindle are fixed on the knob seat.

In the practicality, fixed screw spare can be fixed on the hinge upright of window.When pressing the button, the lower end of the end of button spindle pushing activity template by carrying on the stator drive pull bar, makes down on the latch thus and carries, and can open window, and because the elastic force of following latch spring resets latch pull bar, activity template, stator, button spindle etc.When need close window, only need the pulling sash, immediate locking when closing.

Sealing, fastness in order to realize closing window add latch, go up plug housing and last latch spring, and last latch is fixed on the plug housing, and last latch spring is placed in the bolt rod.

Because utilization lever principle design, therefore than existing casement bolt more flexibly, freely, durable, one by promptly opening, immediate locking when closing, security reliability is higher, realizes shutting integrated.
