Abstract

The utility model relates to an automatic lock for aluminium alloy sliding windows. The utility model is provided with a lock face fixed on an edge frame of a sash. An incomplete semi-spherical face with an opening is recessed at the center of the lock face towards the inside of the edge frame of the sash. The top part of the semi-spherical face is provided with a supporting ear which is connected with a lock hook through a latch. The lock hook forms a bending shape. One end of the lock hook parallel to the lock face is a chamfered hook head. One end of the lock hook perpendicular to the lock face is positioned at the opening position of the incomplete semi-spherical face, and is a finger trip for bearing pushing force of fingers. The lock hook can rotate around the latch which is provided with a torsion spring for resetting of the lock hook. The lock hook forms a fit with a lock catch fixed on a window frame. The utility model can realize synchronous accomplishment of unlocking and window opening or window closing and locking, and can be conveniently arranged.

Description

Aluminum alloy push-pull window automatic locking

The utility model relates to sash lock, refers to a kind of aluminum alloy push-pull window automatic locking particularly.

Existing aluminum alloy push-pull sash lock mostly is the elongated strip shaped structure, the slide window lock of this structure exists following deficiency: the one, and need pass through operations such as line, saw, file when it is installed at the scene and leave a narrow oblong aperture, not only waste time and energy, and can not guarantee the quality of assembling; The 2nd, whether it in use unblanks to separate with the action of window (or close window and lock), and locks also and will sound out, and it is very inconvenient to operate; The 3rd, the thin cast aluminium of its many employings is made, and installation and use facts have proved that it is easy to fragmentation, and application life is shorter.

The purpose of this utility model will provide a kind of installation very easy, extremely easy to use and long-lived aluminum alloy push-pull window automatic locking exactly.

For realizing this purpose, the aluminum alloy push-pull window automatic locking that the utility model is designed, have a locking face that is fixed on the sash frame, locking face mediad sash frame inner recess forms the imperfect hemisphere face of a band opening, and this imperfect hemisphere face top is provided with a support pad; Lock hook is made the small lever shape of bending, and its bending part links to each other with support pad by latch, and its end parallel with locking face is the eave tile of cutting sth. askew, and it vertical with locking face one corrects and be positioned at imperfect hemispherical opening part, for the finger that bears finger thrust is stumbled.Lock hook can rotate around latch, and latch is provided with the torque spring of guaranteeing that lock hook resets, and lock hook matches with snap close on being fixed on the window frame banding.

Above-mentioned locking face, lock hook and snap close can adopt all that steel sheet is rolling to form.

Advantage of the present utility model is: one, install very easy, the only with hand electric drill bores corresponding hole and bolt hole on the sash frame corresponding to locking face central authorities imperfect hemisphere face place, lock body is placed on it, get final product with bolt again, removed irritating operations such as line, saw, file from.Its two, extremely easy to use, (or close window and lock) two actions of will unblanking and window of this structure are merged into an action and finished, and settle at one go, unblank when promptly windowing, and lock when closing window, and are simple to operation, laborsaving.Its three, this automatic locking adopts the steel sheet drawing, the intensity height is sturdy and durable, and with low cost.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 is a kind of perspective view of aluminum alloy push-pull window automatic locking;

Fig. 2 is the assembling schematic diagram of automatic locking shown in Figure 1 on sash and window frame;

Fig. 3 is the structural representation of this automatic locking (except that snap close);

Fig. 4 is the left view of Fig. 3;

Fig. 5 is the vertical view of Fig. 3.

Aluminum alloy push-pull window automatic locking shown in the figure, has a locking face 1, locking face 1 is fixed on the sash frame 3 by bolt 2, and these locking face 1 mediad sash frame 3 inner recess form the imperfect hemisphere face 4 of a band opening, and these imperfect hemisphere face 4 welded top have a support pad 5.Lock hook 6 is made the small lever shape of band bending, its bending part links to each other with support pad 5 by latch 7, its end parallel with locking face is the eave tile 8 of cutting sth. askew, and it vertical with locking face 1 one corrects the opening part that is positioned at imperfect hemisphere face 4, for the finger that bears finger thrust stumbles 9.Lock hook 6 can rotate around latch 7, and the torque spring 10 of guaranteeing that lock hook resets is housed on the latch 7.Snap close 11 is fixed on the window frame banding 13 by rivet 12, and snap close 11 has 90 ° of bendings, which is provided with a small square hole, and use matches with lock hook 6.Locking face 1, lock hook 6 and snap close 11 are all selected the thick steel sheet drawing of 1-1.2mm for use, assemble.

When needs close window, promote sash, snap close 11 edges hit eave tile 8 hand-holes can be with on the window locks; And need window the time, finger push refers to stumble 9, and lock hook 6 rotates thereupon, and eave tile 8 is deviate from from the small square hole of snap close 11, and sash also moves thereupon and opens.Be to close window to lock or unblank to window and all only need a lateral force to finish.

Claims

1, a kind of aluminum alloy push-pull window automatic locking, it is characterized in that: it has a locking face that is fixed on the sash frame, and this locking face mediad sash frame inner recess forms the imperfect hemisphere face of a band opening, and this imperfect hemisphere face top is provided with a support pad; Lock hook is made the small lever shape of band bending, and its bending part links to each other with support pad by latch, and its end parallel with locking face is the eave tile of cutting sth. askew, and it vertical with locking face one corrects and be positioned at imperfect hemispherical opening part, stumbles for bearing the finger of pointing thrust; Lock hook can rotate around latch, and latch is provided with the torque spring of guaranteeing that lock hook resets, and lock hook matches with snap close on being fixed on the window frame banding.

2, aluminum alloy push-pull window automatic locking according to claim 1, it is characterized in that: above-mentioned locking face, lock hook and snap close are all made with the 1-1.2mm steel sheet.
