Abstract

The utility model relates to a window lock. Only one action need to process unlocking and windowing which are finished simultaneously. With revocation of the acting force, a movable hook and a sliding block respectively restore position under the actions of elastic forces of a torsion spring and a pressure spring. To close the window, the window is pushed in the direction of a fastening piece by a force, and the collision of a bevel (13) of a movable hook with a bevel (14) of the fastening piece (3) produces an acting force of the bevels to make a winding shaft of the movable hook clockwise into a square opening (15) of movable hook. As the acting force of the bevels is disappeared, the movable hook resets under the action of torsion spring force and is tightly buckled in the square opening of the fastening piece. Then six DOF of the movable hook all are limited to lock the window reliably. The window closing also is finished by processing an action. The utility model has the advantages of simple structure, reliability, safety and easy use.

Description

Sash lock

Sash lock is a kind of window lockset, and it is made up of lock body and fasteners.

Sash lock has the sash lock two big classes of " latch " formula and head with lock, and with lock sash lock (as the sash lock of the patent No. 8803201.1) improves on its " latch " sash lock that is original, and tapered end promptly is housed.And " latch " formula sash lock specification is a lot, but structure is the same substantially, is moved up and down by latch and enters snap close, reaches lock or closes window.Window or close window and finish, when windowing, dial " latch " earlier, push hard then and open a window, used two actions by two actions that independently separate.When closing window, push hard the window closure, two actions have also been used in just fastening " latch " then.Action is many makes troubles to use, in addition, " latch " lock and unreliable, because of latch enters by moving both vertically up and down or breaks away from snap close, because the restriction of position, it is very shallow that " latch " enters the degree of depth of snap close, so not compact in the window installation; When above-below direction has big gap, when window lock, up carry as long as handle is equipped with " mortise lock " window, then latch just can break away from snap close, just can promote window, and window is opened.So this " sash lock " uses and is dangerous.

The utility model sash lock is a kind of new construction of switch of design, makes window locking solid and reliable, reduces the action of " opening " and " pass " window, reaches simple in structure, purpose of safety easy to use.

The utility model sash lock adopts the scheme that lever, slide block, spring open-and-close mechanism are arranged.

Sash lock is characterised in that push rod (2), slide block (7), activity collude the opening-closing structure of (4), stage clip (6), torsion spring (5).

The utility model sash lock is simple in structure, locks solid and reliablely, and spring is used as power, and is both laborsaving, reduces action frequency again.

Now illustrate the scheme of sash lock with an embodiment.

Fig. 2 is a sash lock lock body vertical view

Fig. 3 is a sash lock lock body upward view

Fig. 4 is a sash lock fasteners front view

Fig. 5 is a sash lock fasteners left view

Fig. 6 is that front view is colluded in the sash lock activity

Fig. 8 is a sash lock slide block front view

The utility model sash lock is made up of lock body (Fig. 1, Fig. 2, Fig. 3) fasteners (Fig. 4, Fig. 5), and among Fig. 2: (1) is holder (Fig. 1, Fig. 2, Fig. 3), and (2) are push rod (Fig. 7), (3) be supporting base, (4) be that (Fig. 6) colluded in activity, (5) are torsion springs, and (7) are slide block (Fig. 6).(10) be fasteners.

Push rod (2) is installed on the axle (8) of holder (1), and can sway, garden post (9) (Fig. 8, Fig. 2) slide block that the open slot (11) of push rod (2) one ends (Fig. 7) sticks on the slide block (7) leans on an end on inclined-plane to connect stage clip (6), slide block is limited in the groove (12) interior (Fig. 2) of holder (1) and can slides, activity collude (4) be contained in holder (1) upper branching holder (3) the axle on, and can rotate around this axle, torsion spring (5) one end fastening activities are colluded (4), other end connection fixed seat.Activity is colluded on the inclined-plane that is pressed on slide block (7) under the effect of torsion spring power (Fig. 8).

User mode is, lock body is installed on the window of sliding sash, and fasteners is installed on another face-port, colludes with activity to cooperate.Course of action is like this, when windowing, the power inhour acts on push rod (2) handle (Fig. 2), push rod is rotated around axle (8) inhour, and garden post (9) turned right push away, make slide block along (Fig. 2) the compression spring (6) that moves to right of groove (12), simultaneously the slide block inclined-plane up pushes away activity and colludes (4) and break away from fasteners (10).At this moment the state that is in out of sash lock.The direction of power is the direction of mobile window on the push rod owing to act on, so under this power effect, the action that window is unblanked and windowed is carried out simultaneously, only needs an action.After cancelling active force, activity is colluded with slide block and is resetted under the elastic force effect of torsion spring and stage clip respectively.When closing window, power makes window push away toward the fasteners direction, when activity is colluded inclined-plane (14) that inclined-plane (13) (Fig. 6) collides fasteners (8) (Fig. 5) time, the active force on inclined-plane colludes around axle clockwise then in the square opening (15) that the activity of entering is colluded, the ramp effect power that loses is colluded in activity, so reset activity under the effect of torsion spring power, activity is colluded by fastening in the square opening of fasteners, at this moment, activity is colluded six months degree of freedom and all is limited, so the window reliable lock.Close the window also is to finish once a utilization action.

Simple in structure, reliable, the safety of present embodiment, easy to use.
