The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.

A kind of window described in the utility model comprises altogether with the preferred three kinds of embodiment of ventilation lockset: lock 1, tapered end 2, key 3, location-plate 4, installing hole 5, pick-proof lid 6, inserted slot 7, stealthy installing hole 8, dead bolt 9, counter-base 10, lock tongue 11, pick-proof wing 12, flute profile locating hole 13.

Most preferred embodiment one of the present utility model as shown in Figure 1, present embodiment is mainly by lock 1, tapered end 2, key 3, location-plate 4 is formed, but described tapered end 2 axial stretching in the hole of lock 1 moves (seeing the arrow indication among Fig. 1), dead bolt 9 is straight-bar shape and is connected on the tapered end 2, the lock tongue 11 T-shaped (see figure 2)s of dead bolt 9 or special-shaped (see figure 3) or with straight-bar similar shape (see figure 10), lock tongue 11 can rotate (seeing the arrow indication among Fig. 1) under the drive of key 3, have several flute profile locating holes 13 that snap in for lock tongue 11 on the location-plate 4, installing hole 5 places on the lock 1 have inserted slot 7, can insert pick-proof in the groove and cover 6 (see figure 4)s, perhaps installing hole 5 places on the lock 1 have groove, in groove, can embed pick-proof and cover 6 (see figure 5)s, thereby pick-proof lid 6 can prevent that the thief from unloading screw with instrument opens the window, when window very big (or laterally very long), when the thief stretches into manual tool and reaches lockset, can not install the pick-proof lid additional, location-plate 4 (is seen Fig. 6 for straight-bar type or radial type, Fig. 7), straight-plate-type uses more convenient, because the locating hole of back can not move, radial type can put down in the direction of arrows, from attractive in appearance more quite a lot of than straight-plate-type, for preventing that the thief from stretching into knockout screw in the window with hand, at the installing hole place of location-plate pick-proof wing 12 can be set and (see Fig. 1, Fig. 7), to increase the dismounting difficulty; Insert key 3 and rotation during use, make the profile of lock tongue 11 consistent with the flute profile locating hole 13 on the location-plate 4, and tapered end 2 outwards pulled out, fan windows (or a fan window) when shifting the position of the satisfied ventilation needs that will stay onto with two, the flute profile locating hole 13 that the lock tongue 11 of tapered end 2 back is aimed on the location-plate 4 (also can be the locating hole 13 of other special-shaped shapes, down together), promoting tapered end 2 makes tapered end 2 do axial advancement in the hole of lock 1 lock tongue 11 is snapped onto in the flute profile locating hole 13 on the location-plate 4, cycle key 3 makes lock tongue 11 revolutions then, T shape on it is just in time blocked the flute profile locating hole 13 on the location-plate 4, lock tongue just can't withdraw from for 11 this moments, make axially movable tapered end 2 and can adopt Fig. 2, two kinds of forms of Fig. 3, a kind of is rib (see figure 2) separated in installing additional, another kind is the (see figure 3) of vertically slotting on cylindrical, after being fixed on these two kinds of tapered end activities on the lock 1 by pin tapered end 2 is moved in lock 1 as axial stretching, thereby satisfy requirement of the present utility model.

Only need insert key 3 rotation (about 90 °) when windowing, it is consistent with the flute profile locating hole 13 on the location-plate 4 that the T shape head of lock tongue 11 is forwarded to, spurs key 3 then tapered end 2 is retreated along the hole on the lock 1, makes lock tongue 11 withdraw from flute profile 13 fully and just can.Only need window is closed when window need close, this moment, lock tongue 11 was just aimed at first flute profile locating hole 13 on the location-plate 4, and same operation gets final product.

It is very convenient that the utility model is installed, as long as the Yi Dui Yue tooth lock that the owner will move on the window is originally pulled down, this sash lock is screwed on the position of original dress lock gets final product, and need not widen the view burrows, and owner oneself just can finish, and is very convenient.

Most preferred embodiment two of the present utility model as shown in Figure 8, present embodiment and embodiment one are different, the lock 1 of present embodiment is fixed on the counter-base 10, counter-base 10 is fixed on (or on window) on the window frame, as long as the size up and down of lock 1 is greater than the maximum size between two stealthy installing holes 8 on the counter-base 10, its lock body just can cover the mounting screw that exposes to lock 1 when closing locking, the stranger just can't unload lockset this moment, owing to link to each other with hinge between lock 1 and the counter-base 10, so what present embodiment adopted is the method for closing and promptly locking, when window is shifted onto (ventilation state or closed condition), only need lock 1 is closed, the lock tongue 11 of its tapered end 2 afterbodys just can be inserted into (see figure 9) (also can be the locating hole of other special-shaped shapes) in the flute profile locating hole 13 on the location-plate 4, this structure can be saved tapered end 2 moving axially in lock 1, this just makes the tapered end that present embodiment can use any rotation to lock, when lock tongue 11 is inserted in the slotted hole 13, only need screw key 3 just location-plate 4 can be blocked, lock tongue 11 must be that T shape is special-shaped or L shaped etc. in the present embodiment, after stretching into locating hole, rotate to an angle along arrow and just can block location-plate 4 and can not withdraw from and (see Fig. 8, Fig. 9), location-plate 4 can be straight plate in the present embodiment, also can make radial type, for other aspects, basic identical with embodiment one.

Most preferred embodiment three of the present utility model is as shown in figure 10: lock 1 adopts in the present embodiment is the technology identical with embodiment one, and other aspects and the first two embodiment are different, what at first be that the shape of the lock tongue 11 of tapered end 2 back adopts is that to be the rod cross section of straight-bar identical with dead bolt 9, promptly there is not the part that to block, next is that locating hole on the location-plate 4 also adopts the flute profile locating hole being convenient to insert or circular locating hole 13 etc., be straight-bar shape owing to dead bolt 9 in the present embodiment, so require tapered end 2 in lock 1, must move axially and be to have self-locking device, as plum blossom tapered end and skewed slot tapered end etc., by pushing or screw key 3 linearly moves axially dead bolt 9 to reach in the locating hole that snaps on the back location-plate 4, because dead bolt 9 is straight-bar shapes, so present embodiment also has certain requirement to location-plate 4, for preventing that dead bolt 9 from being withdrawed from from location-plate 4 by the thief, location-plate 4 must have certain thickness, just can make dead bolt 9 insert certain degree of depth, so a kind of is that location-plate 4 is made U-shaped (seeing Figure 11), just be to use barred body gain in strength (seeing Figure 12) in addition, because the location-plate 4 that certain thickness arranged is in the back under the setting off of glass, the thief is difficult to lockset be moved big distance and dead bolt 9 is done out from the locating hole of location-plate 4, but present embodiment wants more inferior than the first two embodiment safety.

Tapered end 2 among all embodiment of the present utility model can replace with coded lock, its function is the same, and the installation of this sash lock is very convenient, only needs Yuan Yue tooth lock is pulled down, again with screw this lock is loaded onto at the old place and to be got final product, owner oneself just can finish.

The utility model is rational in infrastructure, safe and reliable, convenient and practical, can satisfy the needs that multinomial function such as window is weighed down in ventilation, antitheft and anti-children.
