Abstract

The utility model discloses a lock for a pushing door window of a building. A main shaft (2) which is sheathed with a spring (3) is arranged in a lock shell (1); one end of a positioning pin (4) is inserted on the lock shell (1), and the other end is inserted into an annular groove which is positioned at the middle part of an upper plain surface of the main shaft (2) and is provided with an inclination angle; a end cap (5) is sheathed on the main shaft (2) and is fixed with the lock shell (1) by screws. So only by pushing the main shaft (2), through the positioning pin (4) which moves and is fastened in the annular groove, the main shaft (2) is extended from the lock shell (1) or retracted to complete the locking or the opening of the pushing door window.

Description

Lock for sliding door and window
The utility model relates to construction and installation safety to be decorated, and anti-a kind of device of usurping especially is installed on the building push-pull door and window.
Use elongated latch lock and semi arch kayser on the common in the market push-pull door and window, they must be installed on the frame of the window that pushes, and fan the window frame that pushes one lock body is installed on one side, on the window frame that pushes that another fan cooperates with it lock or lockhole are installed, the window that pushes like this could can pin or block when closing.Will cut out bigger installing hole at door window frame during installation, workload is bigger; Damage easily during use or be difficult to pin and maybe can't block, the window safe that pushes can't be ensured.
The purpose of this utility model provides a kind of lockset that can use on the various windows that push, it is easy for installation, use is not fragile, the window that pushes that can adapt to different materials is installed and used, under equal conditions reduce, and the material cost of every lock reduces by more than 50 than original latch lock usage quantity.
In order to achieve the above object, the utility model Lock for sliding door and window is made up of lock housing, main shaft, spring, pilot pin, end cap etc., and main shaft places the tubular lock housing, and spring is housed between main shaft and lock housing; Movable pilot pin of installing, the one end is in lock housing, the other end inserts in the annular groove at main shaft middle part, end cap passes the main shaft end and fixes with screw and lock housing, press main shaft, move, block by the circulation of pilot pin in the annular groove at inclination angle is arranged, main shaft is stretched out from lock housing or bounce back, finish the locking or the unlatching of the window that pushes.
The utility model has the advantages that: (1) is simple in structure, and is easy for installation; (2) a pair of window that pushes only need use a lock, reduces the amount of installing and using; (3) reduce over half than common Lock for sliding door and window cost of production.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the right view of lock housing;
Fig. 4 is the vertical view of main shaft.
Lock for sliding door and window illustrated in figures 1 and 2 is made up of lock housing 1, main shaft 2, spring 3, pilot pin 4 and end cap 5, main shaft 2 places tubular lock housing 1, between main shaft 2 heads and lock housing 1 middle part ring-type tabula layer, spring 3 is housed, when main shaft 2 heads and lock housing 1 head were a plane, spring 3 was uncompressed state; Be shaped on a rectangular platform on ring-type tabula layer top, lock housing 1 middle part, in the slotting hole thereon of an end of one piece of inverted U-shaped pilot pin 4, pilot pin 4 can be swung flexibly; Cut a part at main shaft 2 axis bodies along the axle center, form an elongated square planar, or be cut into two elongated square planars of step-like formation, on this plane,, leave an annular groove with pilot pin 4 other end correspondence positions; The hole of end cap 5 is made with main shaft 2 axis body cross sections identical shaped, makes end cap 5 movable sleeves on main shaft 2, and is fixed up with two pieces of screws 6 and lock housing 1, prevents that main shaft 2 from rotating, and play the guiding role.Screw 7 is installed is used for taking the screw and the window frame that pushes to fix.
As shown in Figure 1 and Figure 4, the annular groove on the main shaft 2, upper groove 8 are that a left side is high right low, and the inclination angle is 5~30 °, and low groove 10 is that a left side is low right high, and the inclination angle is 5~30 °; When using hand propelled main shaft 2, spring 3 is compressed, pilot pin 4 moves to left relatively along upper groove 8, drop into than in the low transition flat grooves 12 of upper groove 8 left ends, unclamp hand this moment, then pilot pin 4 will be blocked by central island 9 in the position of the seat groove 11 lower than transition flat grooves 12 under the effect of spring 3, and main shaft 2 protracts and inserts another fan and push in the hole of window frame, and this a pair of window that pushes is promptly locked.When promoting main shaft 2 once more, pilot pin 4 drops into than in the also low low groove 10 of seat groove 11, loose one's grip this moment, main shaft 2 is return under spring 3 tension force effects, pilot pin 4 moves to right relatively along low groove 10, and finally rests on upper groove 8 right-hand members, and main shaft 2 bounces back from the hole of another fan doorframe and window frame, at this moment, the window that pushes is in the state of being unlocked.
