Description

The push button lock for sliding door and window

The utility model is a kind of door and window lock, particularly a kind of push button lock for sliding door and window.

Along with the progress of society, people's housing condition is constantly improved, and house and other various buildings are installed or reequiped the more and more of sliding door and window, and the level of finishing is also higher.Yet the lock for sliding door and window of supplying on the market still mainly be type of push and pull up down and laterally pinch pull-type.These lock for sliding door and window have following deficiency:

1, volume is bigger, and consumptive material is more, and cost is higher; 2, profile is attractive in appearance inadequately, and the surface of lock is left with the finger push-and-pull or pinched the groove that draws, and is installed on the door and window, and an end of screw cover also is exposed to the appearance at the door and window side bar back side; 3, firm inadequately, latch hook, lock are disconnected bad easily in the bump of closing the doors and windows.

The purpose of this utility model is to propose that a kind of volume is less, and consumptive material is less, and cost is lower, good looking appearance, and the surface is concordant, firmly solid push button lock for sliding door and window.

Can realize the purpose of this utility model by following technical proposals: be circular or the square lock tube seat that is recess between it is characterized in that merely hitting by one, mix a "T"-shaped button sheet-pile, and put a spring at the inner segment of "T"-shaped button sheet-pile, section is loaded onto one "  " shape male tongue hook outside it, fixes with nut; Mix an inverse-T-shaped female tongue hook again and constitute.It also is a fritter square plate, the recess that the centre position is rounded or square, its bottom is the plane, that the center on plane is provided with is parallel about in the of one, both sides are the elliptical aperture of arc, thereby form a lock tube seat, two parts respectively have a pod with the surface is parallel about it, and respectively are drilled with a countersunk head screw; One than lock tube seat on the slightly little circle of recess area or square plate center extend one section up and down parallel, both sides be the cylindroid of arc, thereby become a "T"-shaped button sheet-pile; Section cover one spring within it, after cylindroid is inserted the elliptical aperture of lock tube seat bottom, and run through and stretch out its outer section, overlap "  " shape male tongue hook thereon, refill top nut and fix; At this moment, the button Face of button sheet-pile and lock tube seating face coincide, and are on the plane; In order to stablize this state, the diameter of the cylindroid outer section of button sheet-pile is slightly littler than its inner segment part, in order to avoid the position of male tongue hook on the button sheet-pile is difficult to fix, the button panel surface can not be kept at grade with the lock tube seating face; Open a square opening on the positive moderate position of slide door or window side bar, matching with the lock tube seat up and down respectively is drilled with a hole, then the lock tube seat is embedded, and load onto screw, but screw head need not touched the slide door or window side bar back side; Open a circular hole in appropriate location, door and window side bar side again, an inverse-T-shaped female tongue hook is loaded onto in the back in appropriate location, jamb side.So far, can normally use.When closing, only need move with the hand door and window, its inertia can be closed and be locked; During unlatching, only need male tongue hook to be separated with female tongue hook, can draw back door and window with a finger Push button plate.

Effect of the present utility model is:

1. saving material.The lock for sliding door and window of existing minimum also wants little by about 1/3rd on its volume ratio market; 2. technology is simple.Because deft design, processing are also simpler and easy than existing door and window lock; 3. cost is lower.Because of above-mentioned advantage, so cost is obviously lower; 4. good looking appearance.Because button panel of the present utility model surface is fit on the plane with the lock tube seating face, be installed in and seem more smooth on the slide door or window, and two screws on the lock tube seat all need not touch the back side of door and window side bar, so the other end of screw can be as existing lock for sliding door and window, screw one end is exposed to the appearance at the back side, therefore just more attractive in appearance; 5. firm and durable.Because impact site such as dead bolt of the present utility model designs more closely, and is capable of expansion and contraction, so anticollision more; 6. easy for installation.The utility model volume is little, and the hole that need open is also little, so installation work-hour is also less relatively.

Below in conjunction with accompanying drawing the utility model is further set forth:

Accompanying drawing 1 is a front schematic view of the present utility model.

Accompanying drawing 2 is located the horizontal section vertical view for accompanying drawing 1A-A '.

Accompanying drawing 3 is located the longitudinal profile left view for accompanying drawing 1B-B '.

Referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, on lock tube seat 1, assemble a "T"-shaped button sheet-pile 2, section puts a spring 4 within it, its outer section puts "  " shape male tongue hook 5, load onto nut 6, with lock tube seat 1 from lower to upper or from top to bottom, insert the top or the bottom of the square opening of holding successfully in advance in slide door or window side bar 9 fronts, whole lock tube seat is all embedded in the hole in door and window side bar 9 fronts, down or upward move again, make it up and down just in time insert pod 7 on the lock tube seat 1 in both sides, after screw is contained on countersunk head screw 3 and the screw 8, the lock tube seat is fixed on the door and window side bar 9, the back open a circular hole in door and window side bar 9 sides, again in relevant position, sliding jamb 12 side, by screw 11, load onto an inverse-T-shaped female tongue hook 10, can come into operation.
