Abstract

A core replaceable hockey lock includes a housing having a space defined therein. An installation hole is defined in one end thereof and a slit is defined in the inner periphery of the installation hole. An insertion hole is defined in the housing and communicates with the slit. A deadbolt is rotatably installed in the installation hole and has a recess which is located corresponding to the slit. The deadbolt has at least one passive member connected thereto which is located in one end of the housing. A positioning plate is inserted in the slit and the recess to axially position the deadbolt. A positioning pin is inserted into the insertion hole and positions the positioning plate. The hockey lock can use different cores installed therein such as six-bead core, seven-bead core or bead-replaceable core. The user needs only one key to unlock all of the hockey locks.

Claims

1. A hockey lock comprising:

a housing having a space defined therein, an installation hole defined in one end thereof and a slit defined in an inner periphery of the installation hole, an insertion hole defined in the housing and communicating with the slit;

a deadbolt rotatably installed in the installation hole and having a recess which is located corresponding to the slit, the deadbolt having at least one passive member connected thereto which is located in one end of the housing;

a positioning plate inserted in the slit and the recess so as to axially position the deadbolt, and

a positioning pin inserted into the insertion hole and positioning the positioning plate.

2. The hockey lock as claimed in claim 1, wherein a bridge member is fixed in the space and has a positioning portion.

3. The hockey lock as claimed in claim 2, wherein the housing has a fixing hole, the bridge member has a connection hole which is located corresponding to the fixing hole, a positioning member extends through the fixing hole and the connection hole to fix the bridge member in the space.

4. The hockey lock as claimed in claim 1, wherein the positioning plate is a curved plate and has a flat face which is located corresponding to the positioning pin.
