1. A latch assembly with automatic returning bolt, comprising:
a chassis having a planar base board formed with a first punching slot and a second punching slot, a pair of supporting boards and a guiding board integrally protruded from the base board, wherein the guiding board is laterally arranged between the pair of supporting boards, wherein a bolt-mounting seat is defined by the pair of supporting boards and the guiding board cooperatively, wherein the pair of supporting boards consist of a first supporting board and a second supporting board, wherein each of the supporting boards is respectively formed with a receiving hole correspondingly positioned to cooperatively define a bolt-shifting space there-between that has a bolt-travel axis, wherein the guiding board is slotted with a guiding slot extending substantially aligningly with the bolt-travel axis; a bolt having a main shaft, a lateral-guiding post, and a restricting portion laterally arranged on a periphery surface of the main shaft, wherein the main shaft is installed in the bolt-shifting space slidably through the receiving holes of the supporting boards along the bolt-travel axis, wherein as the main shaft slides in the bolt-shifting space, the restricting portion is slidably arranged in the guiding slot, thereby limiting a travel range of the bolt; and wherein the first supporting board is located at a turning place between the first punching slot and the second punching slot, wherein the second supporting board is located above the first punching slot; and an elastic element sleevingly disposed over the main shaft of the bolt, concurrently installed between and in contact with the restricting portion of the bolt and the first supporting board of the chassis, for providing a biasing force on the bolt, so as to keep the main shaft thereof protruding from the second supporting board in a default configuration. |
