Description

The austral window latch

The utility model relates to a kind of latch that is used for door and window.Existing aluminium alloys, plug-type two fan structures of the general employing of plastic-steel window, window colludes the both sides of being located at window frame.A kind of aluminum alloy push-pull door and window lock of CN 2213216Y patent disclosure, being equipped with on the side of window sash frame up and down can axially movable dead bolt, one end of dead bolt is provided with spring, dead bolt also joins with shifting block, be fixed with the snap close axle on the window frame, the snap close axle is provided with the hole that is complementary with the dead bolt other end, and corresponding termination is processed with the slope respectively.The CN2191259Y patent provides a kind of slide door or window safety lock, establish knob in the round hole on lock body, offer chute on the knob, this chute leads to arc groove by elongated slot in the termination and forms, establish pilot pin on the lock core, the corresponding coupling with chute of pilot pin is in the termination up and down of closing, be in when opening straight trough, and the rotation knob makes leads the lock action, reaches the purpose of lock core location.Existing two window latches, its window colludes thiner, damages easily, and firmly rocks to take off often and collude phenomenon, also forgets easily sometimes to shut two latches, and reliability, safety are relatively poor.

The purpose of this utility model aims to provide a kind of coincidence place that is installed in two-light frame, replaces two angle catchs, the austral window latch that security reliability is good with an angle catch.

The utility model is provided with plug housing, surface push-rod, stage clip, press spring base, bearing pin, spring, spring base.Plug housing is provided with the push rod groove, and the perforation fixing hole is established at two ends, and the lower end of surface push-rod is a bending hook part, and push-and-pull up and down in the push rod groove of embedding plug housing, and inclined plane part is established at the middle part, the back side of surface push-rod, and the stage clip fixing hole is established on the top of surface push-rod.Press spring base is arranged at the last fixing hole of plug housing and the stage clip fixing hole of surface push-rod, and stage clip is fixed on the press spring base.Plug housing, surface push-rod and stage clip and press spring base are formed an assembly.Spring base is the cap shape, and an end of bearing pin inserts in the through hole at spring base top, and spring is inserted in bearing pin and between the shaft shoulder of bearing pin is bottom spring base.Bearing pin and spring and spring base are formed another assembly.

During use, the inboard of window frame in plug housing is installed on, the inboard of window frame in spring base is fixed in, and the top of bearing pin contacts the inclined plane part of surface push-rod.Corresponding pin shaft hole is established corresponding to bearing pin afterbody place in inboard at outer window frame.When closing window, the bending hook part of surface push-rod lower end is upwards boosted, the inclined plane part of surface push-rod upwards slides, and pushing tow bearing pin and insert the pin shaft hole of outer window frame is finished the action of locking window simultaneously.Both reliable, safety have been saved material and set-up time again, and window two fan windows only need an angle catch.
