Description

Door lock and housing Technical Field The application relates to the technical field of locks, in particular to a door lock and a shell. Background In some plants, automation devices, such as robotic arms, are provided within the housing. The housing has an openable door that can be opened by a person and into the shell of the housing when an automation device within the housing fails. For safety reasons, after a person has entered the housing, the door must be in an open position so that the person can leave the housing at any time. In the prior art, the door lock is usually arranged in the middle of the door, and holes are usually required to be punched in the door for installation. However, in some cases, the door is made of glass, and cannot be perforated, so that the door lock that needs to be perforated in the prior art cannot be installed. Disclosure of utility model The application provides a door lock and a shell, which are used for solving the technical problem that the door lock can be installed only by punching holes on the door in the prior art. In a first aspect, the present application provides a door lock for locking or unlocking a door of a housing, the door lock comprising: The fixing seat is configured to be fixedly arranged at the bottom of the shell and is provided with a longitudinally extending guide part, and a longitudinally extending through hole is formed in the guide part; A foot pedal having a connection groove, the foot pedal being liftably provided on the guide part through the connection groove; A shaft connected to the foot pedal and penetrating in the through hole, and A resilient element connected to the shaft to apply an upward force to the shaft; wherein the door lock has a locked state and an unlocked state, When the door lock is in the locked state, the upper end of the shaft protrudes from the upper end of the through hole under the action of the elastic member and is located at a locked position in which the upper end of the shaft is higher than the lower edge of the door; When the door lock is in the unlocked state, the upper end of the shaft moves downward under the action of the foot pedal, and descends from the locked position to an unlocked position in which the upper end of the shaft is below the edge of the door. In a second aspect, the present application provides a housing comprising: A housing; A door movably provided on the housing, a lower edge of the door being provided with a locking hole, and The door lock according to the first aspect, wherein the door lock is provided at a bottom of the housing, and an upper end of the shaft can be inserted into the locking hole or separated from the locking hole. Compared with the prior art, the application at least comprises the following beneficial effects: The fixing base is arranged at the bottom of the shell, so that the door lock is integrally positioned at the bottom of the shell instead of the door, and therefore holes are not required to be punched in the door. Furthermore, the state of the door lock can be changed by means of a foot pedal, for example from a locked state to an unlocked state, and the resetting of the door lock, i.e. the re-switching from the unlocked state to the locked state, can be achieved by means of an elastic element. When the door is in the open position and after the foot leaves the pedal, the upper end of the shaft is higher than the lower edge of the door, so that the door cannot enter the closed position from the open position, the door is always in the open position, and the safety of personnel is ensured.
