Description
The utility model relates to the building doors and windows accessory, particularly a kind of push-pull switch window automatic locking.
Existing sliding sash switch lock comprises pedestal, lock panel, quiet hook seat, moveable lock hook etc., and the profile of the lock panel of this lock is a groove shaped, has switch to dial plate in groove, and the compression spring in the control latch hook adjustable shelf is windowed or locked window.This lock need lean on when locking manually to advance with gravity because the compression spring in the latch hook is harder, and the adjustable shelf stroke is shorter, makes movable latch hook under the effect of impact force, makes window locking with quiet latch hook collision, is easy to cause quiet lock to break; And lock panel and seat surface out-of-flatness, the practicality aesthetics is relatively poor, sliding sash inconvenience.
The purpose of this utility model is a kind of novel sliding sash switch automatic locking of design, simplify the lock body internal construction, change the mode that latch hook is locked by the impact force that manually advances with gravity, making locks changes the mode that automatically locks of not having impact, no frictional resistance into, and lock panel is equal with pedestal, and lock panel can design various pattern decoratives, and is both artistic and practical, rational in infrastructure, long service life.
Sliding sash switch automatic locking of the present utility model is made up of pedestal, locking face touch panel, moveable lock hook, quiet hook seat, and it is characterized in that: pedestal is the rectangle framework, is provided with spring base, extension spring seat and torsion spring seat at the back side of pedestal; Being cast into tabular locking face touch panel back has a conical contact tip, the locking face touch panel on top, the middle part is fixed on the pedestal by spring, extension spring respectively; The moveable lock hook bottom that has the circular arc gib head is fixed on the torsion spring seat, the relative rank of conical contact tip at top and locking face touch panel back; Torsion spring one end is fixed on the torsion spring seat, and the other end is fixed on the moveable lock hook; Quiet hook seat is a rectangular plate shape, and the front portion is provided with the gib head that is connected mutually with moveable lock hook.
The manner of execution of sliding sash switch automatic locking is, moveable lock hook is installed in locking face touch panel back, and being tried hard to keep to hold by torsion spring often is in 0 degree angle locking state; The locking face touch panel keeps panel mutually smooth with seat surface by spring and extension spring, and the conical contact tip that the locking face touch panel is provided with later is relative with moveable lock hook to be held in the mouth.When the locking face touch panel press...withes one's finger when moving, the extruding force of conical contact tip makes moveable lock hook turn to 20-25 degree angle to break away from quiet lock by 0 degree angle circular arc, is in unlocking condition; When finger left the locking face touch panel, torsion spring power was returned to 0 degree angle locking state with moveable lock hook, and it is smooth that locking face keeps.The gib head of moveable lock hook is a circular arc, and it moves also for circular arc turns to, moveable lock hook and quiet lock zerofriction force, thus can very clever draw together window to be opened, lock is survivable, durable; When closing window, the inertia force of window makes the quiet lock of the very light automatic very naturally insertion again of moveable lock hook live sash lock.After locking, face can prevent sled outside window.
The utility model has the advantages that locking face is smooth attractive in appearance, can adopt the pattern decorative lock panel, the lock body internal construction is simple, closes the window light sensitivity that automatically locks, and windows and finishes by drawing simultaneously, it is convenient that the matter heavily fortified point is durable, installation is cleaned, and cost is low, is applicable to various push pull type window uses.
