Abstract
The invention discloses a lock bar for a household lock. The lock bar comprises a lock body connected with a door and a buckling plate connected with a door frame. A lock cylinder is arranged in the lock body. An upper shifting block is arranged on the lock cylinder. A lower sliding sleeve is fixedly arranged in the lock body through a supporting frame. A lower push rod matched with the lower sliding sleeve is slidably arranged in the lower sliding sleeve. A fixing block is arranged at one end of the lower push rod. A lower shifting block matched with the upper shifting block is arranged on the fixing block. A transverse lock bar body is arranged at the other end of the lower push rod. A lower slot matched with the transverse lock bar body is formed in the lock body and the buckling plate. The portion, between the transverse lock bar body and the lower sliding sleeve, of the lower push rod is sleeved with a reset spring. One end of the reset spring abuts against the transverse lock bar body, and the other end of the reset spring abuts against the lower sliding sleeve. A transverse lock cavity matched with the transverse lock bar body is formed in the buckling plate.
