Problems solved by technology

[0003] However, the door locks currently on the market are fixed on the front panel of electrical equipment (such as a washing machine) by screws. There are certain defects in this method: the door lock of the washing machine is installed with screws, and the screws are easy to rust, and holes appear on the panel of the washing machine. Corrosion, door locks are not firm, etc. Second, it is time-consuming and labor-intensive to reinforce the door lock with screws, which is not conducive to improving production efficiency

Abstract

The invention provides a door lock base (114) and a door lock. The door lock base comprises a door hook hole (102), a first bottom plate (115), a second bottom plate (116), a first upward-protruding suspension support arm (108), a second upward-protruding suspension support arm (109), a first boss (111) and a second boss (112) which are arranged on the upper surfaces of the first suspension support arm and the second suspension support arm correspondingly, and a first resilient anti- disengagement elastic piece (151) and a second resilient anti-disengagement elastic piece (152) arranged under the first suspension support arm and the second suspension support arm. The two upward-protruding suspension support arms (108, 109) are adopted and the bosses on the support arms are clamped in holes of a front panel of an electrical device by means of the elastic deformation of the support arms, so that the door lock can be fixedly secured to the inner side of the front panel of the electrical device. The resilient anti-disengagement elastic pieces (251 / 252) are arranged under the bosses, so that the installation is facilitated and the bosses are prevented from moving downward after installation and are prevented from being disengaged from the holes because of vibration.

Description

technical field [0001] The invention relates to a door lock for electrical equipment, in particular to a mechanism for fixing the door lock on the inner side of the closing door of electrical equipment such as washing machines. Background technique [0002] At present, all electrical equipment needs to install a door lock mechanism with higher safety. Taking the large drum type washing machine as an example, the locking of the top plate (top plate) needs to be installed with a fixed door lock mechanism to prevent the large drum type washing machine from rotating at high speed when it is running (or still running due to inertia after it stops running). High-speed rotation), may cause harm to the human body. [0003] However, the door locks currently on the market are fixed on the front panel of electrical equipment (such as a washing machine) by screws. There are certain defects in this method: the door lock of the washing machine is installed with screws, and the screws are...
