Abstract

A numeral lock housing structure including a lock housing composed of two halves mated with each other. Each of the halves is formed with at least one lateral face and a front face forward extending from the lateral face. Two edges of the front faces form two mating edges mated with each other. A corner section between the lateral face and the front face of at least one of the two halves is formed with at least one numeral wheel window. At least one numeral wheel is mounted in the numeral wheel window for controlling a lock bolt to lock/unlock the numeral lock. The numeral wheel window extends into the front face without crossing the mating edge thereof. Therefore, the mating edges of the two halves of the lock housing will not be slotted so that the structure of the front face of the lock housing is kept integrated. The numeral wheel is positioned between the lateral face and front face so that the numeral wheel has larger turning angle each time the numeral wheel is turned.

Claims

1. A numeral lock housing structure comprising a lock housing composed of two halves mated with each other, each of the halves being formed with at least one lateral face and a front face forward extending from the lateral face, two edges of the front faces forming two mating edges mated with each other, a corner section between the lateral face and the front face of each of the two halves being formed with at least one numeral wheel window, at least one numeral wheel being mounted in the numeral wheel window for driving a locking/unlocking unit disposed in the lock housing, the numeral wheel window extending into the front face without crossing the mating edge thereof, wherein the numeral wheel windows are symmetrically respectively formed on the two halves of the lock housing.

2. A numeral lock housing structure comprising a lock housing composed of two halves mated with each other, each of the halves being formed with at least one lateral face and a front face forward extending from the lateral face, two edges of the front faces forming two mating edges mated with each other, a corner section between the lateral face and the front face of each of the two halves being formed with at least one numeral wheel window, at least one numeral wheel being mounted in the numeral wheel window for driving a locking/unlocking unit disposed in the lock housing, the numeral wheel window extending into the front face without crossing the mating edge thereof, wherein the locking/unlocking unit is controlled by a lock bolt drivingly connected with the numeral wheel, wherein the numeral wheel windows are symmetrically respectively formed on the two halves of the lock housing.
