Description

Trap formula automatic window catch

The utility model relates to the aluminium alloys sash lock, particularly a kind of trap formula automatic window catch.

General on the market common sash lock is broadly divided into two big classes at present, and a class is a bolt-type; Another kind of is the tapered end formula, has the people again both to be combined as a whole afterwards and makes with lock single face sash lock.In actual applications, these a few class sash locks all have its characteristics separately, but there is a common weak point to be: to window or close window and must finish by two actions that independently separate respectively, and locked groove is narrow, can only hold two fingers operates, spend than great strength and window could be closed or drawn back, and damage is pointed easily, therefore be with inconvenience to the user.

The purpose of this utility model provides a kind of simple in structure, and is easy to operate, can make to window, unblank or close window, shut the trap formula automatic window catch finished of step.

Technical solution of the present utility model is: the upper surface of lock housing is a plane, mid portion has a drop front, the two bottom sides forward lower comer of lock housing is gone up the supporting base that the place, angle is provided with the tape spool hole respectively with the back, and drop front is passed on the supporting base that spring is arranged on lock housing forward lower comer both sides by axostylus axostyle.The two ends that are positioned at axostylus axostyle are provided with torque spring, and spring one end is fixed on the axostylus axostyle, and the other end is arranged on the supporting base.

The utility model compared with the prior art, have simple in structure, compact, characteristics such as easy to operate, safe, laborsaving, in addition, because sash lock and handle design are one, the drop front on lock housing surface is the part of handle in actual applications, unblanks or close window to shut the purpose that single stepping is finished thereby reached to window.

Below in conjunction with accompanying drawing the utility model is illustrated:

Fig. 1 is Facad structure figure of the present utility model;

Fig. 2 is the structural representation of snap close;

Fig. 3 is the upward view of Fig. 1;

Fig. 4 is the rear elevation of Fig. 1;

Fig. 5 is the vertical view of Fig. 1;

Fig. 6, Fig. 7 are fundamental diagram of the present utility model.

Shown in Fig. 1-5: this automatic window catch is made of jointly lock housing 1, drop front 2, movable dead bolt 3, movable block 4, axostylus axostyle 5, supporting base 6, axis hole 7, screw 8, spring 9, snap close 10.Lock housing wherein shown in Figure 11 upper surface is a plane, mid portion is provided with drop front 2, the two bottom sides forward lower comer is gone up the supporting base 6 that the place, angle is provided with tape spool hole 7 respectively with the back, movable dead bolt 3 is arranged on the lock housing forward lower comer, wear lock housing both sides axis hole and spring 9 by axostylus axostyle 5 and be fixed on the supporting base 6, utilize acting force of the spring to swing up and down.Said drop front 2 is arranged in the lock housing back and goes up the angle, and on the axis hole of lock housing both sides and fix, it can swing up and down, the rebound reset execution by an axostylus axostyle and two spring cross-under.Lower through-hole on the middle part of lock housing, four limits are cavity walls, and respectively there are two supporting bases 6 that have axis hole 7 both sides, and movable dead bolt 3 is to be that the lever principle of fulcrum is worked with the centre.

Operating principle of the present utility model is shown in Fig. 6,7: when closing window, window is pushed to fixedly snap close 10, and when movable dead bolt 3 contacts with fixing snap close 10 when answering back to, dead bolt 3 is locked by snap close 10 roof pressures.This moment is because fixedly snap close is interior porose, and movable dead bolt utilizes the active force of spring to stick into downwards and hooks snap close 10 in the hole, thereby window is by automatic blocking.When unblanking (as shown in Figure 7), finger is put in drop front 2 enter in the lock chamber, drop front 2 presses the dead bolt tail end, and front end is raised, and window is also drawn back when in the other direction spurring sash lock is opened simultaneously, has reached and has unblanked to window one step completed purpose.
