The specific embodiment

Snap-lock mechanism shown in Figure 1 comprises a snap-lock mechanism, and as shown in Figure 1, snap-lock mechanism is installed on the sash 1, and sash 1 is by means of a packing bar/weather strip 2 and window frame 3 sealings.Latch mechanism also comprises a locking seat 4, and this locking seat 4 is installed on the window frame 3 and with latch mechanism and engages.

Latch mechanism comprises a latch 5 that has a roller 6, and this roller is installed rotating around the axle vertical with the figure paper plane.Latch 5 links to each other with a Connection Element 8 by one first link pin 7, and Connection Element 8 links to each other with a seat element 10 by one second link pin 9 conversely.Latch 5 also links to each other with an executive component 12 of latch mechanism by one the 3rd link pin 11.Yet executive component 12 links to each other with seat element 10 by one the 4th link pin 13, thereby can pivot round the axle vertical with the diagram plane.

Executive component 12 has a handlebar 16, and handlebar 16 extends along the direction vertical with the diagram plane, this point as can be seen from Figure 2, handlebar 16 can be by people's grasped, thereby comes latch mechanism and window.The radius of curvature of a first side 28 of handlebar 16 is approximately 20mm, and we can find that the handlebar work efficiency of such radius of curvature learns well.Radius of curvature is very poor less than the ergonomics of the handlebar of 6mm, and scratch user's danger is arranged.A preferably moulding of handlebar 16, the rod of hollow, cost is moderate and save material.Preferably handlebar 16 is moulding, engage with the corresponding propulsion plant of executive component 12, and slip joint preferably, this point can be as seen from Figure 1.

Seat element 10 can be fixed on the sash 1 by the leg in the hole that reaches sash 1 15 as seen from the figure.Reliable connection between sash 1 and the seat element 10 can be screwed in the screw of hollow leg 15 by the opposite side from sash 1 and realize.Executive component 12 has 17, the three link pins 11 of a slit to be positioned at it.As can be seen from Figure 1, by a helical spring 18, link pin 11 deflections also contact with the end of slit 17.Executive component 12 passes through a disc spring 19 to the counter clockwise direction deflection.

When lock is used as a common latch lock, that is, when sash 1 is closed, sash 1 will pass locking seat 4.Therefore, when link pin 11 pressed from slit 17 with slit 17 terminal contacts, the pressure that latch 5 overcomes spring 18 is forced in the locking 4.As shown in Figure 1, when the roller 6 of latch 5 passes front end 21, latch 5 will turn back to locked position, and at this moment, roller 6 engages and locking sash 1 with a locking plane 22 of locking seat 4.

Open the window and realize by following operation, at clockwise direction press operation element 12 shown in Figure 1, therefore, the latch 5 that has roller 6 is from returning with the joint of catch surface 22 around the 4th link pin 13 for the power that overcomes disc spring 19.Joint by the elasticity tongue 24 on cam on the Connection Element 25 and the base assembly 10, latch lock will rest on open position as shown in Figure 3, even but break away from an easy rate by on the locking direction executive component 12 being applied small pressure maintaining body.

Executive component 12 can be equipped with a lid (only showing cross section), and this is stamped and is used for covering executive component 12 Hes, for example with the flat side that is connected of latch 5.

Handlebar 16 and executive component are designed to when direction A from Fig. 1 locks, handlebar has hidden the major part of executive component 12, for example, and when the surface 30 of executive component 12 and handlebar 16 are concordant, the overall profile of lock seems very graceful and neat, and promptly design is fine.

Fig. 4 shows the snap-lock mechanism of a prior art.The prior art snap-lock mechanism is similar structure, but as can be seen handlebar 116 first side have a projection 116 ', this is shortcomings for handlebar 16 on ergonomics, because projection 116 ' and when operating by the grasping handlebar, the user may abrade user's finger.Also have, as can be seen from Figure 1, the handlebar of the lock of prior art and the clearance C between the sash ' little with respect to the clearance C of lock of the present utility model, another kind of form is, the size in gap remains unchanged, this means to provide a kind of executive component 12 that has a handlebar 16, and the whole height of executive component 12 is littler, makes latch mechanism seem more neat and graceful.This embodies in another embodiment of the utility model shown in Figure 7.In Fig. 7, the distance C of the existing latch mechanism among distance C and Fig. 4 ' equate, and for whole height, H among Fig. 7 _{Always, new}Than H among Fig. 4 _{Always, existing}Little.

Fig. 5 shows the stereogram of locking seat 4.The design of locking seat 4 is practical and grace as can be seen, because antetheca 31 and sidewall 32 have hidden the groove of locking seat 4, and on the locked position of window or door, the roller 6 of latch 5 also is hidden in the groove at least in part.Preferably, locking seat 4 has a slit, and this slit and screw join and incompatiblely will lock the window frame part that seat 4 is installed to window or door, can transfer so lock a position of 4.Preferably the width of the groove of locking seat 4 is bigger than the length of the roller 6 that engages, and allows the inaccurate installation of latch mechanism like this.

From Fig. 6 a and Fig. 6 b, as can be seen, can there be one to be suitable for being installed on the window frame independently an assembled tube latch sleeve pipe and a sash stopping element 33.Element comprises that the axle bush 34 of a barrel bolt on the sash (not shown) with respect to window frame locking sash, for example, can polish window glass.Element also comprises a stop surfaces 35 that is used for the pivoting action of stop sash, therefore, can avoid the possible damage to locking mechanism.
