The utility model discloses a bolt for a safety window, which is a safety bolt for being installed on the window. The bolt for the safety window is composed of a bolt rod controlled by a self-return spring and a sliding hole locking sheet which is on the upper part of the bolt rod. To a certain extent, the bolt for the safety window can prevent the window from the damage caused by forgetting to hook a wind hook or the failure of the wind hook. When no body is at home, a small lock can be additionally mounted on the bolt for the safety window; even if the glass is broken, the window sash can not be opened; the effect of safety protection is reached.

Description

Bolt for safety window

The utility model is to close the safety pin device that window is used.Belong to the architectural hardware class.

Existing latch very easily causes window arbitrarily to be blown by wind in case of forgetting to go up window catch or window catch when malfunctioning, causes glass to damage; In addition, meeting under robber's situation, the criminal only need damage a sheet glass, just can open whole fan window.

It is a kind of improved on the original basis that the purpose of this utility model is to provide, and can prevent the safe window latch of above-mentioned defective.

The technical solution of the utility model is: change the structure of original latch, its safety device is mainly by base plate, wedge bolt rod, return spring, handle, movable lockhole sheet, fixedly lockhole sheet etc. constitutes; When window was got back to fastening position, because the acting in conjunction of wedge bolt rod and return spring, the wedge bolt rod promptly inserted in the matching board automatically, reaches the purpose of closing window under external force.After closing window, owing to be arranged on fixedly lockhole sheet and the movable lockhole sheet of the shape that is arranged on wedge bolt rod top on the base plate on same horizontal plane, can hang a little lock in the isometrical circle of two lockhole sheets, this moment, whole window was then locked, be difficult for easily opening, even damaged the window upper glass, also can only be like this.

Compare with latch with conventional window, the utility model has the advantages that: the first, can the automatic close window family in order to avoid damage window-glass.The second, after closing, window can lock, play certain antitheft effect.

Accompanying drawing 1 is the structural representation of safe window with latch.

Now in conjunction with the accompanying drawings the utility model is described in detail:

Wherein: (2)-wedge bolt rod, (3)-base plate, (5)-pad, (6)-handle, (8)-movable lockhole sheet, (7)-fixedly lockhole sheet, (1)-matching board, (11)-seat hole, (4)-return spring.

Its main feature is to be with a return spring (4) on the wedge bolt rod (2) that is through between (3) two holes of base plate (11), the upper/lower terminal of this return spring (4) respectively has pad to stop, it is fixing by nut (10) that handle (6) is installed in the top of wedge bolt rod (2), wedge bolt rod top is installed with movable lockhole sheet (8), and is fixing by nut (9); Be provided with simultaneously fixedly lockhole sheet (7) on base plate, can insert matching board automatically when window is closed, wedge must be made in the end of wedge bolt rod (2), its α angle should be greater than 45 °.

Its course of work is: when with portable handle (6), the wedge bolt rod moves on (2), return spring (4) compressive deformation, and movable lockhole sheet this moment (8) and fixedly lockhole sheet (7) dislocation, window is in opening.Otherwise, when window under external force, when reaching closed condition, because wedge bolt rod (2) top is to carve angle α for greater than 45 °, stressed back wedge bolt rod (2) moves up, under return spring (4) tension force effect, insert in the matching board (1), window is closed; Movable lockhole sheet this moment (7) is on the same horizontal plane with fixing lockhole sheet (8).For reaching antitheft purpose, can between two lockhole sheet apertures, hang a little lock, cause the purpose that this can reach the present invention.

Bolt for safety window is simple in structure, suitable, has both kept the performance of original latch, has again safety protection function simultaneously.
