Description

Slide window lock

The utility model relates to sash lock, and particularly a kind of sliding sash is with locking.

In the existing slide window lock, some can be finished with an action when close closing, but need finish a plurality of actions when windowing, some is finished by an action when windowing in addition, but its structure adopts torque spring, and spring is tired easily, application life is short, and rely at least one as fulcrum, make product processing complicated, the cost height.

The purpose of this utility model is to provide a kind of open and close window all only to finish with an action, and slide window lock simple in structure, firm.

The utility model is achieved by the following technical solution: referring to accompanying drawing, this slide window lock is by lock body And fixedly snap close 9 forms, and lock body is provided with panel 1, handle 2 and movable snap close 3. Panel 1 is provided with fixing Spring base 5 and spring base chamber 8 also are connected, and spring 4 is enclosed within on the fixing spring seat 5. Movable snap close 3 with 2 approximate vertical of shaking hands also are connected. Respectively there is a movable bullet that is connected as a single entity with it on movable snap close 3 both sides Spring abutment 6. Be fixedly connected with rear fender 7 in 8 ends, spring base chamber, two movable spring seats 6 are limited in spring Seat chamber 8 interior activities. Movable spring seat 6 peripheral size match with spring base chamber 8 inner rim sizes, make activity Spring base 6 can the 8 interior flexible activities in the spring base chamber, do not have again displacement all around. The worker of this sash lock It is as follows to make principle: be contained in lock body on the window in the situation that is not subjected to external force, movable spring seat 6 is by spring 4 Be pressed on the rear board 7. When closing window, staff is as long as push away window on the corresponding window frame that fixing snap close 9 is housed, Need not to contact sash lock, when movable snap close 3 during with fixing snap close 9 bump, the inclined-plane on the movable snap close 3 is with solid Inclined-plane on the lock button 9 interacts, and produces a downward component movable snap close 3 is passed downwards, works as work After moving snap close 3 slipped over the inclined-plane of fixing snap close 9, movable snap close 3 just lost the fixedly pressure of snap close 9, two Reset under the effect of limit spring 4, the gib head of snap close 9 is buckled in the button hole of movable snap close 3 thereby make fixedly, Sash lock is locked. When windowing, only need shake hands 2 to the direction plate of windowing is moving, because handle 2 and movable snap close 3, Movable spring seat 6 is connected, one side this moment two movable spring seats 6 just withstand rear fender, become A fulcrum. When handle 2 was moving to the direction plate of windowing, movable snap close 3 also moved down simultaneously, until live When moving snap close 3 broke away from the gib head of fixing snap close 9, window just can pull open, and this process staff is only used an action Just can finish fenestration procedure.

The utility model has the advantages that: the open and close sash lock is easy to operate, and simple in structure, firm, compares with the sash lock of torque spring with traditional axle that is provided with, and its manufacturing procedure is much simple, the prolongation in application life, and cost is also low than original.
