Abstract

A locking apparatus combined with a fastener to control locking/unlocking thereof. The locking apparatus includes a housing and a female fastener. The housing defines a cavity in which a numeral wheel locking unit is mounted. The female fastener defines a cavity in which a controlling unit is disposed. In a locked state, the locking unit and the controlling unit respectively detain a first end and a second end of a male fastener. The locking unit includes a valve block which can be horizontally and vertically displace to release the first end of the male fastener. The controlling unit includes a rotary section, a reactor and a driven unit which are disposed on the rotary section. A key can be inserted into the rotary section to drive and rotate the rotary section, making the reactor and the driven unit rotated into an unlocked state to release the second end of the male fastener.

Claims

1. A locking apparatus combined with a fastener to control locking-unlocking thereof, the locking apparatus comprising a housing and a female fastener, the housing defining a cavity in which a locking unit is mounted, the female fastener defining a cavity in which a controlling unit is disposed, the locking unit including a numeral wheel for operating the locking unit into a locked state or an unlocked state to release a male fastener, the controlling unit including a rotary section, a reactor and a driven unit which are disposed on the rotary section, whereby a key is inserted into the rotary section to drive and rotate the rotary section, making the reactor and the driven unit rotated into an unlocked state to release one end of the male fastener, wherein the locking unit includes a valve block having a fixed end connected with a lock core of the numeral wheel, when the numeral wheel locking unit is in an unlocked state, the valve block being permitted to horizontally displace, whereby a free end of the valve block is disengaged from a wall of the housing, a resilient member being disposed on lower side of the fixed end to always support the valve block and permit the valve block to be perpendicularly disposed to lever a restricting section.

2. The locking apparatus combined with a fastener to control locking/unlocking thereof as claimed in claim 1, wherein the restricting section is pivotally connected with the housing and includes an arm for detaining the male fastener.

3. The locking apparatus combined with a fastener to control locking/unlocking thereof as claimed in claim 1, wherein the male fastener includes a first end, a shoulder section formed on the first end and a second end having legs which are detained by the female fastener, whereby the first end is inserted into an opening of the housing with the arm of the restricting section grasping the shoulder section of the first end.
