Description

Pincerlike antitheft automatic locking moves sash lock

The utility model relates to a kind of automatic locking and moves sash lock.

At present common aluminium alloys moves sash lock two big classes: 1, limit lock, though its energy automatic locking, very easy opening do not have anti-theft feature outside window, and the both direction at window frame during installation will be slotted, and takes a lot of work and inconvenience is installed; In addition, each window will be installed two sash locks, has increased cost.2, middle lock, present domestic in the middle of lock also have severally, as lock in the middle of the pulling and inserting type, it can not automatic locking and easily open outside window, to slot on the window frame during installation and could install, not only inconvenience but also take a lot of work another kind of moon formula hook lock, install inconvenient, can not automatic locking, and inconvenient operation.

The purpose of this utility model provides six lockings of a kind of energy, and installation, easy to operate pincerlike antitheft automatic locking move sash lock.

The technical scheme that realizes above-mentioned purpose is: the antitheft automatic locking of a kind of pincer moves sash lock, have lock body and dead bolt, lock body is made up of lock housing, a pair of lock pincers and locking spring and rivet, and the lock pincers are hinged on lock housing by rivet, on the lock pincers locking spring is housed, the dead bolt front portion has the guiding arrow.

After adopting technique scheme, owing to have the guiding arrow on the dead bolt, after the lock pincers cooperate, can not only automatic locking, easy to operate, and can realize six lockings in top to bottom, left and right, front and rear of window having strengthened anti-theft feature.Simultaneously,, thereby reduced cost, and not be used on the window frame when installing and slot because the part of lock is few, simple in structure, very convenient.

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

Fig. 5 is the left view of lock body part shown in Figure 4 when the jaw open configuration;

Fig. 6 moves the another kind of example structure schematic diagram of sash lock for the pincerlike antitheft automatic locking of the utility model;

Fig. 7 is the lateral view of lock body part among Fig. 6;

Fig. 8 is the vertical view of lock pincers among Fig. 7;

Fig. 9 is structural representation when moving sash lock locking shown in Figure 6.

Shown in Fig. 1,2,3,4,5, the pincerlike antitheft automatic locking of the utility model moves sash lock and has the lock body 8 that is contained on the interior window frame 1, be contained in the dead bolt 5 on the outer window frame 6, lock body 8 is made up of lock housing 4, a pair of lock pincers 2 and locking spring 7 and rivet 3, lock pincers 2 are hinged on lock housing 4 by rivet 3, on the lock pincers 2 locking spring 7 is housed, the front portion of dead bolt 5 has guiding arrow 5-1.As shown in Figure 1, 2, the jaw 2-1 of lock pincers 2 and caliper 2-2 are at grade.

Shown in Fig. 1,5, a pair of lock pincers 2 are hinged on lock housing 4 by two rivets 3, also can make the middle projection of a pair of lock pincers 4 overlapping up and down, and only use a rivet 3 hinged, and this conversion also drops within the protection domain of the present utility model.

During installation, lock body 8 is installed on interior window frame 1 side, and dead bolt 5 is installed on the plane of outer window frame 6, also is that lock body 8 is mounted on the mutually perpendicular plane of two window frames with dead bolt 5.

It is work like this that the pincerlike antitheft automatic locking of the utility model moves sash lock: a pair of lock pincers 2 are under the effect of locking spring 7, and jaw 2-1 is in normally off.When closing window, the jaw 2-1 of the lock pincers 2 in the guiding arrow 5-1 of the dead bolt 5 on the outer window frame 6 inserts automatically on the window frame 1, lock pincers 2 active forces that overcome locking spring 7 open jaw 2-1, after guiding arrow 5-1 all enters jaw 2-1, lock pincers 2 reset under the effect of locking spring 7, and vise the neck 5-2 of dead bolt 5, about finishing, the action of six lockings in all around.When windowing, pressing lock clamps the flanging 2-3 at 2 rear portions, overcome the active force of locking spring 7, the jaw 2-1 of lock pincers 2 is opened, pulling simultaneously moves window, and dead bolt 5 just can be deviate from from the jaw 2-1 of lock pincers 2, has finished the action of windowing, after hand leaves lock pincers 2, lock pincers 2 auto-closing jaw 2-1 under the effect of locking spring 7.

Among the another kind of embodiment of the present utility model, lock clamps 2 shape conversion to some extent shown in Fig. 6,7,8,9, and also promptly the jaw 2-1 and the caliper 2-2 of lock pincers 2 are perpendicular.During installation, lock body 8 and dead bolt 5 be installed in respectively that two of moving window frame parallel or overlapping plane on.The pincerlike antitheft automatic locking of this structure moves sash lock and is specially adapted to automobile and moves on the window.Operating procedure is the same with aforementioned operating procedure.

The pincerlike antitheft automatic locking of the utility model moves sash lock in use as long as respectively have two installing holes on lock housing 4 and dead bolt 5, open the connecting hole of screw or rivet as long as on window frame, need not slot, only can fix, thereby install easily with four screws or rivet.This lock is applicable to that series alloys such as 90,828,76,73,70 move window, also is applicable to automobile with moving window, is the existing renewal product that moves sash lock.
