Description

A kind of sash lock reversing arrangement

Technical field

The utility model relates to sash lock, refers to the sash lock of Fang Xin with handles especially.

Background technology

Present sash lock uses wide general, has replaced traditional latch, and sash lock is easy to use, basic security under the general situation.Sash lock is produced the back list marketing by manufacturer, the user then removes to select sash lock according to own window, user's window has plenty of a left side and opens, having plenty of the right side opens, the sash lock of opening on a left side to be produced when forcing manufacturer to produce sash lock like this and also the sash lock that open on the right side will be produced, could satisfy user's needs like this, this must increase the investment of manufacturer, has also just increased the cost of sash lock.Another side will understand fully earlier when the user buys sash lock that a left side is opened or the right side repurchases after opening, and is easy to during purchase get wrong; The house to one that adds the user regularly can be fitted up, or changes the layout in the house, causes the reverse unlatching of original window, original like this sash lock is just of no use, can only be to buy the sash lock that oppositely to open on the market, not only increase user's expenditure burden, also cause waste.

Summary of the invention

The purpose of this utility model provides a kind of sash lock reversing arrangement, and it can go commutation with the direction user that window is opened at any time, has reduced spending, has avoided waste, and has reduced the investment of manufacturer, has reduced the cost of sash lock.

Technical solution of the present utility model is that a box body is arranged, the box body size adapts with lock housing stage casing cavity, box body has one to run through the end, the circular hole of face, the position of circular hole all adapts with the Fang Xin that runs through lockhole with size, a peach of dialling of being inserted in Fang Xin is in advance arranged in the box body, dialling the peach bottom is disc, the disc upper surface is provided with the boss platform with symmetrical two places of center hole, dial the peach top and be provided with hyoplastron, hyoplastron is like the horseshoe shape, horseshoe U-shaped opening two ends is provided with the cylinder tongue, be provided with two juts at the hyoplastron bottom surface, a jut is arranged on described U-shaped bottom one side, and reach offside place, U-shaped bottom, another jut is arranged on offside proximal head place, described U-shaped bottom, is provided with elastic device above hyoplastron, and described cylinder tongue box body one sidewall pointed is provided with the circular hole that adapts with two cylinder tongues.

The above elastic device is an elastic ring.

Operating principle of the present utility model is, when the box body side of being inserted in core and after inserting in the cavity of lock housing stage casing, driving Fang Xin when handle upwards draws clockwise rotates, side's core drives dials peach, the boss platform of dialling peach drives the jut of hyoplastron bottom surface and drives the hyoplastron slip, when handle is handed up, dialling that peach turns clockwise is down hyoplastron is pulled back and to make the cylinder tongue withdraw in the lock housing, if with handle when pressing down, dialling peach is that hyoplastron is pushed ahead under the rotation counterclockwise then, it is interior and sash lock is good that the cylinder tongue promptly stretches out lock housing straight cutting window frame buckle, above-described hyoplastron bottom surface crescent moon projection is last, people's tongue shape projection that is to say the direction that window is opened left at the lock of windowing in following time.

When window is opened to the right, just with box body vertical direction turnback be installed in the lock housing after, also promptly this moment the hyoplastron bottom surface the crescent moon projection down, and people's the state of tongue shape projection when last.

More than this commutation, as long as user oneself is in simple operations once, very convenient.

The utility model has the advantages that can be with the direction of window unlatching, and the user oneself goes commutation at any time, has reduced spending, has avoided waste, and has reduced the investment of manufacturer, has reduced the cost of sash lock.
