Description

Lock for sliding door and window

The utility model relates to sash lock, particularly a kind of lock for sliding door and window.

Chinese patent ZL96242022.8 utility model discloses a kind of lock for sliding door and window, this sash lock is made of lock frame, movable button, torque spring and twisted axis, torque spring is installed in the lock frame around twisted axis with movable button, torque spring one end is being pressed the lock frame, the other end is being pressed movable button, and this structure has overcome traditional " latch " class sash lock and windowed and unblanking or closing window and shut to need two shortcomings that action just can be finished.But weak point is this sash lock with axle installs movable button and deposits in the lock body supporting with torque spring, have complex structure, and torque spring is compared with compression spring, also exist long-term the use to be easy to generate metal fatigue, cause camber of spring, torque spring loses elastic force, shortens product application life.Some product is for solving above-mentioned shortcoming, and the elastic force that strengthens torque spring prolongs life of product, more requires great effort when the result uses.

The purpose of this utility model provides the lock for sliding door and window of a kind of simple in structure, rapid operation, long service life.

The utility model lock for sliding door and window, comprise lock frame, movable button, compression spring, base plate and stay hook, movable button is L-shaped, L shaped leading edge portion is porose to match with stay hook, rear edge part stretches into the lock frame as handle, movable button is installed between base plate and the lock frame and can rotates flexibly, and lock frame and movable button respectively are provided with the compression spring reference column, and compression spring is installed on the compression spring reference column of lock frame and movable button.

Snap close of the present utility model and handle design are one, and adopt compression spring to reset, and in actual applications, drive snap close during pull handle and rotate, and reaching unblanks to window or close window shuts the purpose that single stepping is finished.Compared with prior art, have advantages such as simple in structure, rapid operation, long service life.

Below in conjunction with accompanying drawing the utility model is illustrated:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a rear elevation of the present utility model;

Fig. 3 is a vertical view of the present utility model;

Fig. 4 is the A-A cut-away view of Fig. 1;

Fig. 5 is the B-B cut-away view of Fig. 1;

Shown in Fig. 1～5: lock for sliding door and window, comprise lock frame 1, movable button 2, compression spring 3, base plate 4 and stay hook 5, movable button 2 is L-shaped, L shaped leading edge portion porose 6 matches with stay hook 5, rear edge part stretches into lock frame 1 as handle 7, movable button 2 is installed between base plate 4 and the lock frame 1 and can rotates flexibly, and lock frame 1 and movable button 2 respectively are provided with compression spring reference column 8,8 ', and compression spring 3 is installed on the compression spring reference column 8,8 ' of lock frame 1 and movable button 2.
