The present invention relates to a push button type-door lock comprising: a housing (10); a latch (20); an installation bracket (30); and a push button (40). The housing (10) has an opening part (101) formed on one side. The latch (20) is elastically installed inside housing by means of a first coil spring (206) to protrude through the opening part (101). The installation bracket (30) is coupled to an opening part formed on the front surface of the housing (10). The push button (40) comprises; a leg part (403) and a roller (405). The leg part (403) protrudes from the interior of the push button (40) to be inserted into a guide groove (301) of the installation bracket (30). The roller (405) is installed on an end of the leg part (403) to be in contact with the slope groove (201) of the latch (20) to allow the latch (20) to protrude. The push button type-door lock can be conveniently installed and provides an accurate and precise operation performance, thereby achieving high operation reliability. |
