Driver of window lock

Abstract

The invention discloses a driver of a window lock. The driver comprises a main body and a base plate, wherein the main body is provided with a gearing which comprises a driving gear, a first driving rod and a second driving rod; one end surface of the driving gear is provided with a cylinder bulge which is jointed with a through hole arranged on the main body in an embedding mode; the inside surfaces of the rod parts of the first driving rod and the second driving rod are respectively provided with a rack meshed with the tooth part of the driving gear; guiding limit ribs, which are located bybeing matched with guiding limit grooves arranged at two sides of the base plate, are respectively arranged below the rod parts of the first driving rod and the second driving rod; and the end edges of the first driving rod and the second driving rod are respectively provided with a connecting bulge, and the connecting bulges are located by being matched with displacement slots arranged at two ends of the main body. The driver provided by the invention has the advantages that the tooth part and rack of the driving gear are mutually matched, the guiding limit ribs and the guiding limit groovesare mutually matched, and the cylinder bulge is jointed with the through hole in an embedding mode, thereby enabling the bidirection displacement of the first driving rod and the second driving rod to be realized under the action of external force.

Description

technical field [0001] The invention relates to a window lock, in particular to a driver of the window lock. Background technique [0002] There are many kinds of doors and windows used in buildings now. Some of them are driven by gears and racks and the handle has a fixed arc rotation. The one-way door and window swing driver cooperates with the lock pin to lock or open the door and window. This kind of swing driver has a complicated structure. Many parts are required, resulting in higher manufacturing costs, and it is easy to cause the lock pin to shake, thereby affecting the sealing and locking performance of doors and windows. In addition, the reliability of one-way locking can no longer meet the needs of modern life. In view of this, door and window locks with two-way locking function have appeared one after another on the market. [0003] Chinese Utility Model Patent No. 03280006.1 discloses a door and window lock with two-way locking. The driver includes two driving...

Problems solved by technology

However, this kind of transmission only drives one driving bar to move because the driving gear, and the direct force between the driving bar and the driving gear is only one of the driving bars, and the other driving bar is through the transmission gear arranged between the two driving bars. The transmission can only achieve movement; and in the case of a relatively large external force, it may cause slippage between the driving gear teeth and the stressed driving bar teeth, causing the driving gear to deviate from the driving bar, thus affecting the performance of two-way locking or opening
