Abstract

A door and window lock is composed of a lock pin component and a lock catch. The lock pin component comprises a tubular lock sleeve, a pressure spring, a G shape lock pin and an unlocking button. The hook head of the G shape lock pin is corresponding to the position of the lock catch, and contact with each other to shape an inclined mechanism. The component force which produced by the impact force when the lateral arc face of the lock catch works on the inclined lateral face of the hook head drives the G shape lock pin axis overcoming the elastic axis of the pressure spring and moving in axis direction when close door and window, when the lock across the hook head of the G shape lock pin, the G shape lock pin resets by effect of the pressure spring, the hook head of the G shape lock pin tightens the lock catch, and the door and window lock automatically, manually push the unlocking button to overcome the elastic force of the pressure spring, release the hook head of the G shape lock pin from the lock catch, then the door and window are opened. A convex pin is arranged on the lateral wall of the unlocking button. A Z shape and a C shape convex pin guard gib are arranged on the wall of the tubular locking sleeve. Two guard gibs which are parallel with the axis fix the unlocking button on the two limited position, which make the utility model has the functions of locking protecting and unlocking maintaining.

Description

The Plastic steel door sash lock

Affiliated technical field

The utility model relates to a kind of door and window lock, especially plug-type Plastic steel door sash lock.

Background technology

At present, all kinds of push-pull door and window snap closes that use on the market comprise the Plastic steel door sash lock mostly for the rotating handles formula, and as crescent lock, this is locked in out and when closing door and window, all needs manpower earlier door and window to be slippaged and put in place, then rotating handles lock snap close; During door window, just can open after needing manpower elder generation rotating handles to separate snap close, operation inconvenience and volume are bigger, in addition its handle that protrudes from door and window usually hook scrape object nor be attractive in appearance.

Summary of the invention

Existing door and window is latched in operation inconvenience, volume is bigger and inaesthetic problem in order to overcome, and the utility model provides a kind of volume little, attractive in appearance and easy to operate Plastic steel door sash lock.

The utility model Plastic steel door sash lock, constitute by latch members and snap close, described latch members comprises a tubular lock tube and order and is movably placed in stage clip in this lock tube, lock pin, the unlock button that band is handled knob, unlock button is positioned at the uncovered end of tubular lock tube, handle knob and expose outside the tubular lock tube, described lock pin is the cylinder that a cross section and tubular lock tube cavity shape coincide, the cylinder stage casing has short slot, spring side short slot downside is provided with the eave tile that protrudes from this side near cartridge outer surface makes its longitudinal cross-section be G shape, corresponding eave tile place has C shape short slot on the tubular lock tube, snap close is corresponding with the eave tile position, be in contact with one another the formation oblique mechanism, distance that G shape lock pin moves and amount of spring compression are slightly larger than the distance of eave tile and snap close axial overlap, the position of the corresponding snap close of eave tile is provided with and holds groove cave or the slotted eye of inserting eave tile, the unlock button sidewall is provided with protruding pin, on the tubular sleeve wall during homographic solution latching operation protruding pin move axially track and have the wide axially directed groove that is slightly larger than the protruding pin diameter, when unlock button normality and release two limit positions, also have on the pairing tubular sleeve wall of protruding pin two that be parallel to each other and with the gathering sill of axis normal, above-mentioned gathering sill and gathering sill are formed the continuous steerable groove that is Z-shaped or C shape.

The beneficial effects of the utility model are: the plastic-steel door and window that has adopted said structure, in the process that push-and-pull is closed the doors and windows, be installed on distolateral latch members G shape lock pin eave tile of plastic-steel door and window and the snap close collision that is installed on the doorframe and window frame, oblique mechanism makes lateral impact power produce the vertical component along tubular lock tube axis, lock pin is moved axially to the direction of compression press spring, after snap close strides across G shape lock pin eave tile, door and window is closed and is put in place, the active force that collision produces is eliminated, G shape lock pin resets under the effect of stage clip, G shape lock pin eave tile embeds in lock buckling groove cave or the slotted eye, and door and window is sealed automatically; In the time will opening door and window, press unlock button down, make G shape lock pin eave tile break away from snap close, can draw back door and window; In addition, the unlock button sidewall is provided with protruding pin, when to should on the tubular sleeve wall of protruding pin gathering sill being set, limiting the location status and the running orbit of unlock button, in the gathering sill that parallels to the axis when the rotation unlock button makes protruding pin fall into corresponding unlock button normality, limit protruding pin and move axially, reach locking unlock button position purpose, the door and window locking states is protected, and the door and window opposite side then can not be opened door and window, plays the security protection effect; And the following unlock button of pressing, in the gathering sill that parallels to the axis when the rotation unlock button makes protruding pin fall into this state of correspondence behind the G shape lock pin eave tile disengaging snap close, the qualification protruding pin moves axially, make unlock button keep the unlocking condition position, do not need hand to continue to open or close door and window by pushing away unlock button push-and-pull easily, the setting of this structure makes operation more flexible, and is simple in structure and elegant in appearance.
